    Description

    TECHNICAL FIELD



    [0001] The present invention relates to the field of communications technologies, and in particular, to a network access point, a network controller, a network device, and a load control method thereof.

    BACKGROUND



    [0002] At present, wireless local area networks (Wireless Local Area Networks, WLANs) such as WiFi (Wireless Fidelity, wireless fidelity) networks, which are seen as a simple and inexpensive wireless access technology, have been widely deployed as a supplement to cellular networks to alleviate data service load on the cellular networks, and have become popular among users. However, a limited capability of access control by WiFi networks introduces a high likelihood of non-guaranteed communication quality between the WiFi networks and access terminals.

    [0003] In the prior art, a maximum load of a network access point on WiFi networks is introduced to address the challenge in guaranteeing communication quality between WiFi networks and access terminals. Specifically, a terminal is allowed to access a WiFi network through a network access point only when a current load of the network access point is less than the maximum load and an access request signal carrying a first signal of the terminal can be correctly demodulated. When the current load is less than the maximum load, an access request signal sent by a terminal distant from the network access point can also be correctly demodulated. In this case, a communication rate of the terminal is very low, which introduces a high probability of a reduction in spectral efficiency of the whole network access point.

    [0004] CN101959282 discloses a WLAN access control method and a WLAN access control device. The method comprises the steps that: when WLAN access equipment is in an access judgment state, an indicating terminal reports terminal information; a receiving terminal of the WLAN access equipment receives the terminal information reported according to indication, wherein the terminal information carries the current sending power information of the terminal; the WLAN access equipment determines the wireless link route loss of the terminal according to signal intensity when the terminal information is received and the sending power information in the terminal information; and the WLAN access equipment judges the access of the terminal according to the wireless link route loss and an access judgment threshold, and enters control treatment according to a judgment result.

    [0005] WO 2004/004278 A1 discloses a wireless local area network (LAN), and a method of operating the same, that prevents unauthorized users from accessing the wireless LAN. A signal strength of a station attempting to access the wireless LAN is measured. If the signal strength is less than a predetermined threshold value, the system concludes that the station is outside of an authorized geographical area. Such a station attempting to establish a connection is characterized as an unauthorized station, and access to the wireless LAN is denied. The system may also periodically verify that authorized stations remain within the authorized geographical area. A station that has moved outside of the authorized geographical area can be notified or denied further access to the wireless LAN.

    [0006] WO 2006/075937 A1 discloses that, in a multi-access system, an access selection principle is achieved by selecting a signal strength threshold level based on a determined load level (ULOCAL) in a first access network. A new user in an area commonly covered by more than one access network attempts to allocate to the first access network if an experienced signal strength exceeds the signal strength threshold level. Communication utility can preferably be maximised or at least be taken into account by using suitable load level dependencies. By increasing the threshold when the load level approaches the capacity limit, a completely filled first access network is avoided.

    SUMMARY



    [0007] The present invention provides a network device of claim 7, and a load control method of claim 1, so as to improve spectral efficiency of a first network. Preferred embodiments of the present invention are further described in the dependent claims.

    [0008] By using the foregoing solutions, a beneficial effect of the present invention is that: in the present invention, a first signal sent by a to-be-connected terminal is received, and a corresponding measurement parameter is obtained according to the first signal, so as to compare the measurement parameter with an access condition, and when the measurement parameter satisfies the access condition, a second signal is sent, so as to allow access of the terminal, thereby improving spectral efficiency of a first network.

    DESCRIPTION OF EMBODIMENTS



    [0010] The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

    [0011] The present invention provides a network device. As shown in FIG. 1, the network device 120 disclosed in this embodiment includes a receiving unit 121, a processing unit 122, and a sending unit 123. The network device 120 of this embodiment is configured to establish a network connection to a terminal 330. The network includes a first network, and the terminal 330 includes a terminal receiving unit 331 and a terminal sending unit 332.

    [0012] The terminal sending unit 332 sends a first signal for requesting access; the receiving unit 121 obtains the first signal and obtains a load of the first network; the processing unit 122 sets an access condition according to the load, obtains a measurement parameter of the terminal 330 according to the first signal, and compares the measurement parameter with the access condition. If the measurement parameter satisfies the access condition, the sending unit 123 sends a second signal to the terminal 330; the terminal receiving unit 331 receives the second signal, and the terminal 330 accesses the first network according to the second signal, thereby establishing a network connection. The first network is a wireless local area network, and is preferably a WiFi network in this embodiment.

    [0013] In this embodiment, the measurement parameter obtained by the terminal 330 may be a signal strength (RSSI, Received Signal Strength Indicator) obtained by parsing the first signal of the terminal 330, or may be a distance, namely, a terminal device, which is obtained by using a positioning method such as GPRS positioning, between the terminal 330 and the network device 120, or may include both, and apparently may be any other terminal information which can achieve the objective of the present invention. For example, the measurement parameter may be set as an SNR (Signal-to-Noise, signal-to-noise ratio), an SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio), RSRP (Reference Signal Receiving Power, reference signal receiving power), or RSRQ (Reference Signal Receiving Quality, reference signal receiving quality).

    [0014] In this embodiment, because the measurement parameter is a signal strength of the terminal 330 and/or a terminal distance of the terminal 330, correspondingly, that the measurement parameter of the terminal 330 satisfies the access condition includes that the measurement parameter is greater than or equal to a preset measurement parameter threshold, a fluctuation of the measurement parameter is less than or equal to a preset fluctuation threshold of the measurement parameter, or a frequency of fluctuation in the measurement parameter is less than or equal to a preset frequency of fluctuation in the measurement parameter. That the measurement parameter of the terminal 330 does not satisfy the access condition includes that the measurement parameter is less than the preset measurement parameter threshold, the fluctuation of the measurement parameter is greater than the preset fluctuation threshold of the measurement parameter, or the frequency of fluctuation in the measurement parameter is greater than the preset frequency of fluctuation in the measurement parameter.

    [0015] The fluctuation of the measurement parameter indicates an average value of differences among a plurality of sampled measurement parameters of the terminal 330; for example, among three samples, differences between every two adjacent samples are 10 and 8, and then the average value is 9. The preset measurement parameter threshold indicates a preset threshold for accessing the first network by the terminal 330, and the preset threshold is either a fixed value or fixed value range; if the preset fluctuation threshold of the measurement parameter is 7 and the fluctuation of the measurement parameter is 9, the fluctuation of the measurement parameter of the terminal 330 is greater than the preset fluctuation threshold of the measurement parameter, that is, the access condition is not satisfied.

    [0016] The frequency of fluctuation in the measurement parameter indicates an averaged frequency of change in a plurality of sampled measurement parameters of the terminal 330. The preset frequency of fluctuation in the measurement parameter indicates a preset fixed value or a fixed value range for the maximum frequency of change which must not be exceeded if the terminal 330 needs to access the first network; if the value range is 1 to 3 and the frequency of fluctuation in the measurement parameter is 2, the frequency of fluctuation in the measurement parameter falls within the preset value range, that is, the access condition is satisfied.

    [0017] It should be noted that the fluctuation of the measurement parameter and the frequency of fluctuation in the measurement parameter which are included in the access condition of the present invention are only used as examples in the foregoing descriptions, and the present invention is not limited thereto.

    [0018] In this embodiment, the second signal is preferably a frame signal similar to a probe response (Probe Response) frame in the prior art, and in other examples, the first signal sent by the terminal 330 may further include other management frames, control frames, or data frames, such as a GAS Request and an Association Request. In addition, it can be understood that the second signal in this embodiment is reply and/or acknowledgement information of the first signal which is sent by the terminal 330 to the network device 120, and consequently, the second signal correspondingly includes various frames, such as an ACK (Acknowledgement, acknowledgment), a Probe Response, a GAS Response, or an Association Response.

    [0019] After the terminal receiving unit 331 obtains the second signal, the terminal 330 may establish a network connection to the first network, and for a specific connection mode, reference may be made to the prior art, and details are not described herein again. In addition, the terminal 330 mentioned throughout this specification of the present invention is, for example, a mobile phone, but is apparently not limited to a mobile phone, and may be any terminal having a WiFi network access function, including a tablet computer (PAD), and so on.

    [0020] Based on the foregoing, in this embodiment, the network device 120 compares the measurement parameter of the to-be-connected terminal 330 with the access condition which is set according to the first network, and allows access of the terminal 330 when the measurement parameter satisfies the access condition. In this way, communication quality of the terminal 330 accessing the first network can be ensured, and spectral efficiency of the first network is improved.

    [0021] For ease of description, the following embodiments in the whole specification of the present invention are described by using a signal strength to represent a measurement parameter, an access threshold to represent an access condition, and a WiFi network to represent a first network.

    [0022] The present invention further provides a network device of a second embodiment, which is described in detail based on the network device 120 disclosed in the first embodiment. In this embodiment, a load includes a first load, a second load, and a third load, and the first load>the second load>the third load.

    [0023] If the processing unit 122 determines that the load of the first network is greater than or equal to the first load, the processing unit 122 sets the access condition to a first threshold. If the load of the first network is greater than or equal to the second load and less than the first load, the processing unit 122 sets the access condition to a second threshold. If the load of the first network is greater than or equal to the third load and less than the second load, the processing unit 122 sets the access condition to a third threshold. The first threshold>the second threshold>the third threshold.

    [0024] The present invention further provides a network device of a third embodiment, which is described in detail based on the network device 120 disclosed in the first embodiment. In this embodiment, as shown in FIG. 2, the network device 120 further includes a first network controller 130 and a network access point 125 of the first network, and apparently, the first network controller 130 may be disposed in the first network.

In this embodiment, the second receiving unit 126 receives a first signal from the terminal 330, and the second processing unit 127 obtains a signal strength of the terminal 330 according to the first signal, so that the second processing unit 127 compares the signal strength with the access threshold.

Or, the first receiving unit 131 receives a first signal from the terminal, the first processing unit 132 obtains a signal strength of the terminal 330 according to the first signal, and the first processing unit 132 compares the signal strength with the access threshold.

    [0029] The present invention further provides a network device of a fifth embodiment, which is described in detail based on the network device 120 disclosed in the third embodiment. In this embodiment, as shown in FIG. 3, the network access point 125 includes a first network access point 141 and a second network access point 142, the first network access point 141 includes a third processing unit 152 and a third sending unit 153, and the second network access point 142 includes a fourth processing unit 162 and a fourth sending unit 163.

As shown in FIG 4, the network device 120 further includes a second network controller 210, and the second network controller 210 includes a fifth receiving unit 211 and a fifth processing unit 212.

    [0034] Alternatively, the first processing unit 132 updates the access threshold according to the topological relationship between the second network and the first network, the load of the second network, and the load of the network access point 125.

    [0035] In this embodiment, the topological relationship between the first network and the second network may be manually established or automatically established by the network device. The topological relationship refers to that the second network covers the first network. The second network is preferably a cellular network, and types of the cellular network include a GSM (Global System for Mobile Communications) network, a CDMA (Code Division Multiple Access, Code Division Multiple Access) network, a 2G (2nd-generation, second-generation mobile communications technology) network, a 3G (3rd-generation, third-generation mobile communications technology) network, a 4G (4th-generation, fourth-generation mobile communications technology) network, and the like.

In this embodiment, the processing unit 122 further determines whether the first signal sent by the to-be-connected terminal 330 carries a user class, and if the first signal carries the user class, the processing unit 122 sets the access condition according to the load of the network access point 125 and the user class. If the first signal does not carry the user class, the processing unit 122 queries for the user class of the terminal 330 from the first processing unit 132, and sets the access threshold according to the load of the network access point 125 and the user class.

    [0037] Alternatively, the first processing unit 132 determines whether the first signal carries a user class, and if the first signal carries the user class, the first processing unit 132 sets the access threshold according to the load of the network access point 125 and the user class.

    [0039] Alternatively, the second processing unit 127 performs a disconnecting operation according to a terminal whose signal strength is less than or equal to a preset disconnection threshold.

    [0040] In this embodiment, the disconnection threshold is preferably a difference between the set access threshold and a preset fixed value, where the fixed value is 10 and the unit is dbm.

    [0041] In the foregoing embodiments of the present invention, it should be understood that the described embodiments of the network device 120 and the terminal 330 are only exemplary; the described module division is merely division of logical functions, and other divisions may be used in an actual implementation. For example, a plurality of modules may be combined or integrated into another system, or some features may be ignored or not performed. In addition, the coupling or communication connection between the modules may be implemented by using some interfaces, or may be electrical or in other forms.

    [0042] The present invention further provides a load control method of a network device. Referring to FIG. 5, FIG 5 is a flowchart of a load control method according to a first embodiment of the present invention. As shown in FIG. 5, the load control method disclosed in this embodiment is based on the network device 120 shown in FIG. 1. The method includes:

    Step S11: The network device 120 sets an access condition of a first network.
    Specifically, the network device 120 sets the access condition which must be satisfied before a terminal 330 can access the first network.

    Step S12: The network device 120 receives a first signal from the terminal 330, and obtains a measurement parameter of the terminal 330 according to the first signal.

    Step S13: The network device 120 determines whether the measurement parameter satisfies the access condition.

    Step S14: If the measurement parameter satisfies the access condition, the network device 120 sends a second signal to the terminal 330, and the terminal 330 accesses the first network according to the second signal.

    Step S15: If the measurement parameter does not satisfy the access condition, the network device 120 does not send the second signal to the terminal 330, so as to deny access of the terminal 330 to the first network.



    [0043] In step S12 of this embodiment, the first signal may be obtained by the network access point 125 shown in FIG. 2 or may be obtained by the first network controller 130. In the case of obtaining the first signal by the first network controller 130, the network access point 125 transparently transmits the first signal to the first network controller 130.

    [0044] All the following embodiments of the present invention are described by using a signal strength to represent a measurement parameter, an access threshold to represent an access condition, and a WiFi network to represent a first network. Further, the signal strength may be obtained by the network access point 125 by parsing the first signal received by the network access point 125, so that the network access point 125 subsequently compares the signal strength with the access threshold.

    [0045] Or, after obtaining the signal strength, the network access point 125 performs determination on the signal strength according to a preset condition, and sends the signal strength which satisfies the preset condition to the first network controller 130, so that the first network controller 130 compares the signal strength with the access threshold, where the preset condition may the access condition set in step S11, or may be another condition set according to an actual requirement.

    [0046] Further, or, after obtaining the signal strength, the network access point 125 directly sends the signal strength to the first network controller 130, so that the first network controller 130 compares the signal strength with the access threshold.

    [0047] Further, or, the first network controller 130 directly obtains the signal strength by parsing the first signal received by the first network controller 130, and compares the signal strength with the access threshold. It should be noted that for a specific process of obtaining a signal strength according to the received first signal, reference may be made to the prior art, for example, directly measuring the signal strength of the first signal, performing a preset algorithm operation (for example, weighted averaging) on the signal strength of the first signal, or parsing a data packet of the first signal and directly reading a corresponding field.

    [0048] The network device 120 obtains a load of the WiFi network through a WiFi network system or a hardware control program run by the network device 120, and then sets the access threshold according to a preset mapping relationship between loads and access thresholds, where a load may be an air interface load of a network access point AP in the WiFi network, for example, a duty cycle or the number of connected terminals, or may be a load of an AP device, for example, traffic or CPU memory usage, or may be a load of an access point controller AC in the WiFi network, for example, traffic or CPU memory usage. In addition, an access threshold may be a single threshold, for example, -80 dbm, and a network connection is allowed to be established between the terminal 330 and the WiFi network provided that the measurement parameter of the to-be-connected terminal 330 is greater than or equal to -80dbm.

    [0049] In step S12, the network device 120 obtains the first signal from the terminal 330, and there are two manners of obtaining a surrounding WiFi network signal by the terminal 330:

    [0050] One manner is passive scanning, which means finding a surrounding WiFi network by listening for a beacon (Beacon) frame periodically sent by the network device 120. The network device 120 providing a WiFi network service sends a beacon frame periodically, and therefore the terminal 330 may be able to periodically listen for the beacon frame on a list of supported channels, so as to obtain a surrounding WiFi network signal. It should be noted that for power saving purposes, the passive scanning manner may be used preferably.

    [0051] The other manner is active scanning. In a process of enabling and running a WiFi network search function, the terminal 330 periodically searches for a surrounding WiFi network signal. The terminal 330 periodically and proactively sends a probe request (Probe Request) frame containing an SSID (Service Set Identifier, service set identifier) on a list of supported channels, and obtains a WiFi network signal by receiving a probe response frame returned by the network device 120.

    [0052] It should be noted that step S11 and step S12 of this embodiment do not have any connection. Step S11 maybe executed prior to step S12, or S12 is executed prior to step S11, which is not limited in this embodiment of the present invention.

    [0053] Attention is now directed towards step 15. In another embodiment, if the measurement parameter does not satisfy the access condition, the network device 120 may also be configured to send the second signal to the terminal 330, so as to inform the terminal 330 that access to the first network by the terminal 330 is denied. The second signal may be sent by the first network controller 130 shown in FIG. 2, or may be sent by the network access point 125 after the first network controller 130 sends an instruction to the network access point 125.

    [0054] In this embodiment, the network device 120 compares the measurement parameter of the to-be-connected terminal 330 with the access condition which is set according to the load of the network access point 125, and allows access of the terminal 330 when the measurement parameter satisfies the access condition. In this way, communication quality of the terminal 330 accessing the first network can be ensured, and spectral efficiency of the first network is improved.

    [0055] The present invention further provides a load control method of a second embodiment, which is described in detail based on the load control method disclosed in the first embodiment. In step S11, the set access threshold may be in a fixed list which is manually set, and cannot be changed once set. That is, the access threshold is set according to a predefined mapping relationship between loads and access thresholds. The loads in the mapping relationship include a first load, a second load, and a third load, and the first load>the second load>the third load. The access thresholds set by the network device 120 include a first threshold corresponding to the first load, a second threshold corresponding to the second load, and a third threshold corresponding to the third load, and the first threshold>the second threshold>the third threshold. For details, reference to may be made to Table 1 below.
    Table 1
    Load (unit: %)Access threshold (unit: dbm)
    60 -60
    30 -70
    0 -80


    [0056] When setting the access threshold, if the load of the network access point 125 is greater than or equal to the first load 60%, the network device 120 sets the access threshold to the first threshold -60dbm. If the load of the network access point 125 is greater than or equal to the second load 30% and less than the first load 60%, the network device 120 sets the access threshold to the second threshold -70dbm. If the load of the network access point 125 is greater than or equal to the third load 0% and less than the second load 30%, the network device 120 sets the access threshold to the third threshold -80dbm. The first threshold -60dbm>the second threshold -70dbm>the third threshold -80dbm, indicating that when the load of the network access point 125 increases, the access threshold set by the network device 120 increases, the measurement parameter of the terminal 330 that is allowed to access increases, and an access range of the terminal 330 becomes smaller.

    [0057] It should be noted that the three loads, the three corresponding access thresholds, and the corresponding specific values in the foregoing Table 1 disclosed in this embodiment are only used as examples for description; in other embodiments, a person skilled in the art may perform another setting according to an actual requirement, where the another setting is only required to satisfy the requirements that there is a one-to-one mapping relationship between a plurality of loads and a plurality of access thresholds and when the load increases, the access threshold set by the network device 120 increases, and the measurement parameter of the terminal 330 that is allowed to access increases.

    [0058] The present invention further provides a load control method of a third embodiment, which is described in detail based on the load control method disclosed in the first embodiment. This embodiment is based on the network device 120 of the embodiment shown in FIG. 2. As shown in FIG 6, the disclosed load control method includes:

    Step S31: The network access point 125 obtains a load of a first network.

    Step S32: The network access point 125 sets an access threshold according to the load.
    When the network access point 125 is powered on, preferably, a mapping relationship between loads and access thresholds may be manually preset on the network access point 125, and then the network access point 125 performs setting according to the mapping relationship. The mapping relationship may be the mapping relationship, which is disclosed in the first embodiment, between a plurality of loads and a single access threshold, or may be the mapping relationship, which is disclosed in the second embodiment, between a plurality of loads and a plurality of access thresholds.

    Step S33: The network access point 125 obtains a first signal from the terminal 330, and obtains a signal strength of the terminal 330 according to the first signal.

    Step S34: The network access point 125 compares the signal strength with the access threshold.

    Step S35: If the signal strength is greater than or equal to the access threshold, the network access point 125 sends a second signal to the terminal 330, so as to allow access of the terminal 330.



    [0059] The present invention further provides a load control method of a fourth embodiment, which is described in detail based on the load control method disclosed in the third embodiment. A network device of this embodiment is based on the network device 120 of the embodiment shown in FIG. 2, and a difference between the load control method of this embodiment and that of the third embodiment shown in FIG. 6 lies in that:

    [0060] In step S31, the first network controller 130 obtains a load of the network access point 125 of a first network, and in step S32, the first network controller 130 sets an access threshold according to the load of the network access point 125; specifically, when the first network controller 130 is powered on, the first network controller 130 may perform setting according to a preset mapping relationship between loads and access thresholds. After the access threshold is set, the first network controller 130 sends the access threshold to the network access point 125, and then the network access point 125 compares a signal strength of the to-be-connected terminal 330 with the access threshold.

    [0061] The present invention further provides a load control method of a fifth embodiment, which is described in detail based on the load control method disclosed in the fourth embodiment. A difference between the load control method of this embodiment and that of the fourth embodiment lies in that:

    [0062] After the access threshold is set, the first network controller 130 sends the access threshold to the network access point 125, and then the first network controller 130 compares a signal strength of the to-be-connected terminal 330 with the access threshold.

    [0063] The present invention further provides a load control method of a sixth embodiment, which is described in detail based on the load control method disclosed in the fourth embodiment. In step S35 of this embodiment, if the signal strength is greater than or equal to the access threshold, the network access point 125 sends the load of the first network to the first network controller 130, and the first network controller 130 sends a second signal to the terminal 330 according to load balancing of the first network and through the network access point 125, so as to allow the terminal 330 to access the network access point 125 of the first network.

    [0064] The load balancing means that the first network controller 130 allows the terminal 330 to access the first network through a network access point which has a minimum load among a plurality of network access points of the first network. Specifically, when a plurality of network access points 125 is disposed in the first network, if the signal strength is greater than or equal to the access threshold, each network access point 125 sends a load thereof to the first network controller 130, and the first network controller 130 selects a network access point 125 which has a minimum load, and sends the second signal to the terminal 330 through the selected network access point, so as to allow the terminal 330 to access the network access point 125 which has the minimum load.

    [0065] It should be noted that in other embodiments, a rated load may also be set, and if the load of the network access point 125 which has the minimum load and is selected by the first network controller 130 is still greater than or equal to the rated load, access to the first network by the terminal 330 is denied.

    [0066] The present invention further provides a load control method of a seventh embodiment, which is described in detail based on the load control method disclosed in the sixth embodiment. A difference between the load control method of this embodiment and that of the fourth embodiment lies in that:

    [0067] In step S35 of this embodiment, the network access point 125 sends the load of the first network to the first network controller 130, and the first network controller 130 sends a second signal to the terminal 330 after performing load balancing according to the load of the first network, so as to allow the terminal 330 to access the network access point 125 of the first network.

    [0068] The present invention further provides a load control method of an eighth embodiment, which is described in detail based on the load control method disclosed in the first embodiment. In this embodiment, a network device is based on the network device 120 of the embodiment shown in FIG. 3. As shown in FIG. 7, the disclosed load control method includes:

    Step S51: The first network access point 141 obtains a load of the first network access point 141, and the second network access point 142 obtains a load of the second network access point 142.

    Step S52: The first network access point 141 sets a first access threshold according to the load of the first network access point 141, and sends the first access threshold to the first network controller 130.

    Step S53: The second network access point 142 sets a second access threshold according to the load of the second network access point 142, and sends the second access threshold to the first network controller 130.

    Step S54: The first network controller 130 updates the first access threshold and the second access threshold according to the load of the first network access point 141 and the load of the second network access point 142.

    Step S55: The first network controller 130 obtains a first signal from the terminal 330, and obtains a signal strength of the terminal 330 according to the first signal.

    Step S56: The first network controller 130 compares the signal strength with the updated access thresholds.

    Step S57: If the signal strength is greater than or equal to the updated first access threshold, the first network controller 130 sends a second signal to the terminal 330, so as to allow the terminal 330 to access the first network access point 141.



    [0069] In step S54 of this embodiment, the first network controller 130 compares the load of the first network access point 141 and the load of the second network access point 142. If the load of the first network access point 141 is greater than the load of the second network access point 142, the first network controller 130 updates the first access threshold and the second access threshold, so that an updated access threshold of the first network access point 141 is greater than the first access threshold, and an updated access threshold of the second network access point 142 is less than the second access threshold. If the load of the first network access point 141 is less than the load of the second network access point 142, the first network controller 130 updates the first access threshold and the second access threshold, so that an updated access threshold of the first network access point 141 is less than the first access threshold, and an updated access threshold of the second network access point 142 is greater than the second access threshold. If the load of the first network access point 141 is equal to the load of the second network access point 142, which indicates that the to-be-connected terminal 330 may access either of the first network and the second network, the first network controller 130 does not update the first access threshold or the second access threshold.

    [0070] Specifically, in the foregoing updating, the first network controller 130 generates an update value, and performs an operation on the first access threshold and the second access threshold according to the update value. When the update value is an absolute value, the first network controller 130 may directly replace the first access threshold or the second access threshold with the absolute value, so as to obtain an updated access threshold. When the update value is a relative value, the first network controller 130 may add the relative value to the first access threshold or the second access threshold, so as to obtain an updated access threshold. It should be understood that in other embodiments, the first network controller 130 may further generate a first update value and a second update value, and perform an operation on the first access threshold and the first update value and an operation on the second access threshold and the second update value, so as to obtained updated access thresholds.

    [0071] The present invention further provides a load control method of a ninth embodiment, which is described in detail based on the load control method disclosed in the eighth embodiment. A difference between this embodiment and the eighth embodiment shown in FIG. 7 lies in that:
    In step S51, the first network controller 130 obtains a load of the first network access point 141 and a load of the second network access point 142. In step S52 and step S53, the first network controller 130 updates a first access threshold and a second access threshold.

    [0072] In addition, it should be understood that in the examples of this embodiment and the foregoing eighth embodiment, there are two network access points, namely, the first network access point 141 and the second network access point 142 of the first network; in other embodiments, the first network may be configured to include a plurality of network access points.

    [0073] In the foregoing eighth embodiment and ninth embodiment, when a plurality of adjacent networks is networked, access thresholds of a plurality of network access points can be updated correspondingly. In this way, an access threshold of a network access point with a high load can be decreased, and an access threshold of a network access point with a low load can be increased, so that a terminal 330 preferably accesses a network access point with a relatively low load, thereby implementing optimized allocation of network resources, ensuring quality of communication between the terminal 330 and an accessed network, and further improving spectral efficiency of a network access point.

    [0074] The present invention further provides a load control method of a tenth embodiment, which is described in detail based on the load control method disclosed in the first embodiment. In this embodiment, a network device is based on the network device 120 of the embodiment shown in FIG 4. As shown in FIG. 8, the load control method disclosed in this embodiment includes:

    Step S71: The first network controller 130 obtains a load of the network access point 125 of a first network, and the second network controller 210 obtains a load of a second network.

    Step S72: The second network controller 210 updates an access threshold according to a topological relationship between the second network and the first network, the load of the second network, and the load of the network access point 125 of the first network.

    Step S73: The network access point 125 obtains a first signal from the terminal 330, and obtains a signal strength of the terminal 330 according to the first signal.

    Step S74: The network access point 125 compares the signal strength with the access threshold.

    Step S75: If the signal strength is greater than or equal to the access threshold, the network access point 125 sends a second signal to the terminal 330, so as to allow the terminal 330 to access the network access point 125.



    [0075] In this embodiment, the topological relationship refers to that the second network covers the first network, and the two overlap each other to implement networking. The second network is preferably a cellular network covering the first network (WiFi network), and the second network controller 210 is preferably any one of a radio network controller RNC, an evolved NodeB, eNB, a base station controller BSC, and a signaling gateway SGW. In addition, in step S72, the second network controller 210 may update the access condition of the network access point 125 according to Table 2 below.



    [0076] Referring to Table 2, in step S72, when the load of the network access point 125 of the first network is light and the load of the second network is light, the second network controller 210 increases the access threshold, so that an updated access threshold is greater than the access threshold prior to being updated. When the load of the network access point 125 of the first network is light and the load of the second network is heavy, the second network controller 210 decreases the access threshold, so that an updated access threshold is less than the access threshold prior to being updated. When the load of the network access point 125 of the first network is heavy and the load of the second network is light, the second network controller 210 increases the access threshold, so that an updated access threshold is greater than the access threshold prior to being updated. When the load of the network access point 125 of the first network is heavy and the load of the second network is heavy, the second network controller 210 does not adjust the access threshold, so that an updated access threshold is equal to the access threshold prior to being updated.

    [0077] Specifically, in the updating step, the first network controller 130 sends the obtained load of the network access point 125 of the first network to the second network controller 210, and the second network controller 210 generates an update value according to this load and the load of the second network which is obtained by the second network controller 210, and delivers the update value, where the update value is an absolute value or a relative value; the first network controller 130 receives the update value and updates the access threshold of the network access point 125 of the first network. A specific updating process is similar to the updating process of the foregoing eighth embodiment, and therefore details are not described herein again.

    [0078] In other embodiments, after generating an update value, the second network controller 210 does not deliver the update value to the first network controller 130. Instead, the second network controller 210 updates the access threshold of the network access point 125 of the first network, and then delivers an updated access threshold to the first network controller 130. In addition, when the update value is an absolute value, the second network controller 210 may directly replace the access threshold prior to being updated with the absolute value, so as to obtain an updated access threshold. When the update value is a relative value, an updated access threshold may be obtained according to the following formula:

    where
    the reference load is a preset rated load of the second network, and a value range of the adjustment step is (0, 20], where in this embodiment, a default value is preferably 5, and the unit is db.

    [0079] In addition, in step S72 of other embodiments, the first network controller 130 may update the access condition according to the topological relationship, the load of the second network, and the load of the network access point 125.

    [0080] In this embodiment, when a plurality of networks having a topological relationship is networked, an access threshold of a network covered by another network can be updated. An access threshold of a network access point with a high load is decreased, and an access threshold of a network access point with a low load is increased, so that a terminal 330 accesses a network access point with an optimal load, thereby implementing optimized allocation of network resources, ensuring quality of communication between the terminal 330 and an accessed network, and further improving spectral efficiency of network access points of a plurality of networks.

    [0081] The present invention further provides a load control method of an eleventh embodiment, which is described in detail based on the load control method disclosed in the first embodiment. In this embodiment, a network device is based on the network device 120 of the embodiment shown in FIG. 2. As shown in FIG. 9, the load control method disclosed in this embodiment includes:

    Step S81: The network access point 125 obtains a load of the network access point 125.

    Step S82: The network access point 125 obtains a first signal from the terminal 330, and obtains a signal strength of the terminal 330 according to the first signal.

    Step S83: The network access point 125 determines whether the first signal carries a user class, and sets an access threshold according to the load of the network access point 125 and the user class.

    Step S84: The network access point 125 compares the signal strength with the access threshold.

    Step S85: If the signal strength is greater than or equal to the access threshold, the network access point 125 sends a second signal to the terminal 330, so as to allow access of the terminal 330.



    [0082] In step S83 of this embodiment, if it is determined by demodulating that the first signal carries the user class, the network access point 125 sets an access threshold according to the load of the network access point 125 and the user class. If it is determined that the first signal does not carry the user class, the network access point 125 queries, from the first network controller 130, for the user class of the terminal 330 sending the first signal, and sets an access threshold according to the load of the network access point 125 and the user class. For a mapping relationship among user classes, loads of the network access point 125, and access thresholds, reference may be made to Table 3 below.
    Table 3
    Load (unit: %)Access threshold (unit: dbm)
    60% User class is high -80
    User class is low -60
    30% User class is high -90
    User class is low -70
    0% User class is high -∞
    User class is low -80


    [0083] That is, if the load of the network access point 125 obtained by the network access point 125 is 60%, and it is determined that the user class carried in the first signal is high, the access threshold is set to -80dbm. If the load of the network access point 125 obtained by the network access point 125 is 60%, and it is determined that the user class carried in the first signal is low, the access threshold is set to -60dbm. If the load of the network access point 125 obtained by the network access point 125 is 30%, and it is determined that the user class carried in the first signal is high, the access threshold is set to -90dbm. If the load of the network access point 125 obtained by the network access point 125 is 30%, and it is determined that the user class carried in the first signal is low, the access threshold is set to -70dbm. If the load of the network access point 125 obtained by the network access point 125 is 0%, and it is determined that the user class carried in the first signal is high, the access threshold is set to -∞dbm, that is, no access threshold is set. If the load of the network access point 125 obtained by the network access point 125 is 0%, and it is determined that the user class carried in the first signal is low, the access threshold is set to -80dbm.

    [0084] It should be noted that in the example of this embodiment, three loads are set, only two user classes are classified, and the specific values of the access thresholds in the foregoing Table 3 are only used as examples for description; in other embodiments, a person skilled in the art may classify user classes otherwise according to an actual requirement, provided that at a same load level, the higher a user class is, the lower an access threshold is.

    [0085] It should be understood that in other embodiments, when all user classes are high, the network access point 125 may set no access threshold, that is, the access threshold is -∞, and set an access threshold of the network access point 125 only when a user class is low.

    [0086] The present invention further provides a load control method of a twelfth embodiment, which is described in detail based on the load control method disclosed in the eleventh embodiment. A difference between this embodiment and the foregoing eleventh embodiment lies in that:

    [0087] In step S81, the first network controller 130 obtains a load of the network access point 125 of a first network. In step S83, the first network controller 130 determines whether the first signal carries a user class, and sets an access threshold according to the load of the network access point 125 and the user class. That is, if it is determined by demodulating that the first signal carries the user class, the first network controller 130 sets an access threshold according to the load of the network access point 125 and the user class. If it is determined that the first signal does not carry the user class, the first network controller 130 queries for the user class of the terminal 330 sending the first signal, and sets an access threshold according to the load of the network access point 125 and the user class.

    [0088] In addition, in a specific step of setting the access condition in this embodiment, the first network controller 130 generates an update value, and when the update value is an absolute value, the first network controller 130 may directly replace the access threshold prior to being updated with the absolute value, so as to obtain an updated access threshold. When the update value is a relative value, an updated access threshold may be obtained according to the following formula:

    where
    a value range of the adjustment step is (0, 20], where in this embodiment, a default value is preferably 10, and the unit is db, the user class is a user class corresponding to the terminal sending the first signal, and the lowest user class is a preset lowest user class at which the terminal 330 is allowed to access the first network.

    [0089] In this embodiment and the eleventh embodiment, because user classes of to-be-connected terminals 330 are classified, access of a terminal 330 with a low user class is restricted. In this way, class-based allocation of network resources of the first network can be implemented, thereby ensuring quality of communication between the terminal 330 and the first network, and improving spectral efficiency of a network access point 125.

    [0090] The present invention further provides a load control method of a thirteenth embodiment, which is described in detail based on the load control method disclosed in the first embodiment. In this embodiment, a network device is based on the network device 120 of the embodiment shown in FIG. 2. As shown in FIG. 10, the load control method disclosed in this embodiment includes:

    Step S101: The first network controller 130 forms a to-be-disconnected terminal list according to a connected terminal 330 whose signal strength is less than or equal to a preset disconnection threshold, and sends the to-be-disconnected terminal list to the network access point 125.

    Step S102: The network access point 125 performs a disconnecting operation according to the to-be-disconnected terminal list.

    Step S103: The first network controller 130 obtains a load of the network access point 125 of a first network.

    Step S104: The first network controller 130 sets an access condition according to the load of the network access point 125.

    Step S105: The network access point 125 obtains a first signal from a to-be-connected terminal 330, and obtains a signal strength of the to-be-connected terminal 330 according to the first signal.

    Step S106: The network access point 125 compares the signal strength with the access threshold.

    Step S107: If the signal strength is greater than or equal to the access threshold, the network access point 125 sends a second signal to the to-be-connected terminal 330, so as to allow access of the terminal 330.



    [0091] In step S101 of this embodiment, the disconnection threshold is preferably a difference between the set access threshold and a preset fixed value, where the fixed value is 10 and the unit is dbm.

    [0092] The present invention further provides a load control method of a fourteenth embodiment, which is described in detail based on the load control method disclosed in the thirteenth embodiment. A difference between this embodiment and the foregoing twelfth embodiment lies in that:

    [0093] In steps S101 and S102, the network access point 125 directly compares a signal strength of a connected terminal 330 with a disconnection threshold, and the network access point 125 performs a disconnecting operation.

    [0094] In this embodiment and the thirteenth embodiment, before a to-be-connected terminal 330 sends a first signal, a connected terminal 330 whose signal strength is less than or equal to a disconnection threshold is disconnected from the first network, which reduces a load of the first network, thereby ensuring quality of communication between the newly connected terminal 330 and the first network, and further improving spectral efficiency of the network access point 125 of the first network.

    [0095] The present invention further provides a network device, which is described in detail based on the network device 120 disclosed in the first embodiment. As shown in FIG. 11, the network device 120 disclosed in this embodiment includes a receiver 421, a processor 422, and a transmitter 423. The network device 120 of this embodiment is configured to establish a network connection to a terminal 330, where the terminal 330 includes a terminal receiver 531 and a terminal transmitter 532.

    [0096] The terminal transmitter 532 sends a first signal for requesting access; the receiver 521 obtains the first signal and obtains a load of a first network; the processor 522 sets an access condition according to the load, obtains a measurement parameter of the terminal 330 according to the first signal, and compares the measurement parameter with the access condition; if the measurement parameter is greater than or equal to the access condition, the transmitter 523 sends a second signal to the terminal 330; the terminal receiver 531 receives the second signal, and the terminal 330 accesses the first network according to the second signal, thereby establishing a network connection.

    [0097] The present invention further provides a network device, which is described in detail based on the network device 120 shown in FIG. 11. In this embodiment, as shown in FIG. 12, a network device 120 includes a network access point 125 and a first network controller 130 of a first network, the first network controller 130 includes a first receiver 631, a first processor 632, and a first transmitter 633, and the network access point 125 includes a second receiver 626, a second processor 627, and a second transmitter 628.

    [0098] The second processor 627 sets an access threshold according to a load of the network access point 125, and compares a signal strength of a terminal 330 with the access threshold.

    [0099] Or, the first receiver 631 obtains a load of the network access point 125; the first processor 632 sets an access threshold according to the load of the network access point 125; the first transmitter 633 sends the access threshold to the second receiver 626; and the second processor 627 compares a signal strength of a terminal 330 with the access threshold.
