METHOD AND SYSTEM FOR ACCESSING LOCAL NETWORK BY MOBILE TERMINAL VIA HOME BASE STATION SYSTEM

Description

Technical Field

[0001] The present invention relates to wireless communication network, and more particularly, to a method and system for accessing a local network by a mobile terminal via a home base station system.

Background of the Related Art

[0002] A home base station, as a small scale base station installed at home or in office area, is called a home NodeB (HNB) in the 3rd generation (3G) mobile communication system and a home eNodeB (HeNB) in a long term evolution (LTE) system, and can be simplified as H(e)NB for both. In order to reduce the effect to a core network (CN), a home base station gate way is introduced in the home base station system, which is called HNB GW in the 3G system and H(e)NB GW in the LTE system.

[0003] As shown in FIG. 1, the HNB and the HNB GW in the 3G system are network elements in a access network, while serving GPRS (general packet radio service) supporting node (SGSN) and gateway GPRS supporting node (GGSN) are network elements in the CN. The interface between the wireless access network and the core network inherits from the interface between a macro base station and the core network and is also an Iu interface whose physical connection exists in the home base station gate way. From a logical point of view, an application layer protocol of the Iu interface is that a radio access network application part (RANAP) might be distributed in the home base station or the home base station gate way or both, and control messages between the SGSN and the GGSN that are the network elements in the core network use a GPRS tunneling protocol-control (GTP-C) signaling.

[0004] As shown in FIG. 2, the HeNB and the HeNB GW in the LTE system are network elements in the access network, while a mobility management entity (MME), a serving GW and a packet data network gateway (PDN-GW) are network elements in the core network. The interface between the wireless access network and the core network inherits from the interface between the macro base station and the core network and is also a S1 interface whose physical connection exists in the home base station gate way. From a logical point of view, the S1 interface application layer protocol is S1-AP (S1 application part) that might be distributed in the home base station or the home base station gate way or both, and control messages between the MME and the Serving GW, as well as between the Serving GW and the PDN-GW that are the network elements in the core network use the GTP-C signaling.

[0005] For normal mobile services, a mobile terminal (user equipment, UE) initiates a service process via the home base station, and this process has a little distinction from a service process via the macro base station. As shown in FIG. 1, in the 3G system, the procedure for the mobile terminal initiating a data service comprises: after the UE accesses the SGSN, the UE sends a packet data protocol (PDP) context activation request to the SGSN, and the request carries an access point name (APN) of the mobile terminal, that is because for different access points the SGSN might select different GGSN to access. The SGSN acquires address information of the corresponding GGSN node from a database or a server according to the acquired APN of the mobile terminal, and sends a context setup request to the corresponding GGSN; and the GGSN returns a context setup response, then the SGSN returns a PDP context activation acknowledgement to the UE to set up a route between the MS and the GGSN, so as to transmit packet data.

[0006] The home base station is a part of a public land mobile network (PLMN), and it can provide general mobile services for the mobile terminal user; meanwhile, the home base station is a part of the home internal network, so it also should provide the service of accessing the home network for the mobile terminal. Since the home base station already connects to the Internet, for pure surfing service, there is no need to access the Internet via the PLMN core network, and the mobile terminal can directly access the Internet via the home base station completely. Based on the above demands, the 3rd Generation Partnership Project (3GPP) proposed local IP access to provide a method for accessing the home network and directly accessing the services in the Internet via the home base station for the mobile terminal user.
Document D1, MITSUBISHI ELECTRIC: "Addressing Options for S1 inter-HeNB Handovers",3GPP DRAFT; R3-090767, 3RD GENERATION PARTNERSHIP PROJECT (3GPP), MOBILE COMPETENCE CENTRE ; 650, ROUTE DES LUCIOLES ; F-06921 SOPHIA-ANTIPOLIS CEDEX ; FRANCE, no. Seoul, Korea; 20090318, 18 March 2009 (2009-03-18), XP050341153, describes a home base station subsystem and a home NB gateway, whereby communication with the home subsystem takes place via the HeNB gateway.

[0007] According to the requirements of 3GPP, for all the mobile terminal users that are allowed to access the home base station, the local IP function can be used (on the premise that an operator agrees), that is because the implementation scheme has to not change functions of the mobile terminal users. In one implementation, i.e., when the home base station integrates a part of GGSN functions to work as a local GGSN, for a special APN, the mobile terminal indicates to use a local network access function by selecting the APN. According to the existing method, when the SGSN receives the APN including indicating the local access, the SGSN needs to acquire the address of the local GGSN according to the APN and initiate a bearer setup procedure to the local GGSN. Since the home base station is a user equipment, its address information is not included in a network planning range by the operator or its maintenance cost is extremely high. In this condition, the network elements in the core network cannot directly acquire the IP address of the home base station just according to the APN so as to initiate the bearer setup procedure to the local GGSN bond to the home base station, which is also the problem existing in the LTE home base station system so that the mobile terminal cannot access the local network via the home base station.

The first embodiment

[0026] As shown in FIG. 4, in the 3G system, the home base station subsystem comprises a home base station, the local gateway module is a local GGSN bond to the home base station, and the core network management network element is a SGSN. The GTP-C channel is terminated at the home base station, thus it requires the home base station supports the GTP-C protocol while the home base station gateway may not support the GTP-C protocol. The local GGSN module contained in the home base station is used to implement all or a part of the GGSN network element functions, such as saving a PDP context, assigning an IP address to the UE and working as a gateway of a mobile network and an external data network.

[0027] As shown in FIG. 5, the method for accessing the local network by the mobile terminal via the home base station comprises the following steps:

Step 502, the home base station sends an initial UE message to the SGSN, where the message contains the identification of the local GGSN bond to the HNB.

[0028] The identification of the local GGSN might be the IP address, or other identification, such as a fully qualified domain name (FQDN), in which the IP address can be extracted.

[0029] Where there is a home base station gateway, in a practical process, the message sent by the home base station to the SGSN is forwarded to the SGSN via the home base station gateway, which is already known in the prior art.

[0030] In this step, the address of the local GGSN is added by the home base station to the initial UE message, and in another condition, the address can also be added by the home base station gateway to the initial UE message; specifically: the home base station locally configures the address of the local GGSN, and the mobile terminal performs network address conversion when accessing the mobile network, and the home base station gateway takes the converted address as the local GGSN address and adds to the initial UE message.

[0031] Step 503, the UE initiates a PDP context activation request to the SGSN, where the request carries the APN representing the local access.

[0032] Step 504, the SGSN receives the PDP context activation request and determines that the UE needs to access the local network according to the APN, and then the SGSN initiates a bearer setup procedure to the HNB.

[0033] The above-mentioned "initiating the bearer setup procedure to the HNB" is practically initiating a bearer setup procedure (sending a context setup request) to the local GGSN bond to the HNB, and the target IP address is the address acquired in step 502 and this process uses the GTP-C protocol.

[0034] Step 505, the local GGSN bond to the HNB performs admission control to the mobile terminal user according to identification of the mobile terminal user, such as an international mobile subscriber identity (IMSI) or a mobile station international ISDN number (MSISDN); and if the access is allowed, a successful response is returned to the SGSN, otherwise, a failure response is returned.

[0037] Step 507, the SGSN sends a PDP context activation accept message to the UE, the PDP context activation procedure ends, and the UE can access the local data network.

[0038] In step 502 of the above first embodiment, besides of the initial UE message, other Iu interface message or connection-oriented message, such as a uplink direct transmission message, a relocation request acknowledgement or a relocation fulfillment message, can be used.

[0040] In this embodiment, the GTP-C channel is terminated at the home base station, and the method requires that the home base station supports the GTP-C protocol while the home base station gateway does not.

[0041] As shown in FIG. 7, the method for accessing a local network by the mobile terminal via the home base station comprises the following steps.

[0042] Step 701, the UE initiates a RRC connection setup request to the home base station.

[0043] Step 702, the home base station sends an initial UE message to the MME, and the message includes the identification of the local PDN-GW bond to the HeNB.

[0044] The identification of the PDN-GW might be an IP address or other identification, such as a FQDN, that can extract the IP address.

[0045] Where there is a home base station gateway, in practical process, sending the message by the home base station to the MME is forwarded via the home base station gateway, which is already known in the prior art.

[0046] In this step, the address of the local PDN-GW is added by the home base station to the initial UE message, and in another condition, the address can be added by the home base station gateway to the initial UE message; specifically: the home base station locally configures the address of the local PDN-GW, the mobile terminal performs network address conversion when accessing the mobile network, and the home base station gateway takes the converted address as the local PDN-GW address and adds the address to the initial UE message.

[0047] Step 703, the UE sends a PDN connection activation request to the MME, and the request carries the APN representing the local access.

[0048] Step 704, the MME receives the PDN connection activation request and determines that the UE needs to access the local network according to the APN, and the MME initiates a bearer setup procedure to the HeNB.

[0050] Step 705, the local PDN-GW bond to the HeNB performs admission control to the mobile terminal user according to the identification of the mobile terminal user, such as an IMSI or an MSISDN; if the access is allowed, a successful response is returned to the MME, otherwise, a failure response is returned.

[0051] This step is optional.

[0052] Step 706, the local PDN-GW bond to the HeNB assigns an IP address to the UE and sends the IP address to the MME.

[0053] Step 707, the MME sends a PDN connection activation accept message to the UE, the PDN connection activation process ends, and the UE can access the local data network.

[0054] In step 702 of the above-mentioned second embodiment, besides of the initial UE message, other S1 interface messages or UE related messages, such as an uplink non-access stratum (NAS) transmission message, switch request acknowledgement or switch notification, and so on, can be used.

The third embodiment

[0055] In this application, the IP address of the home base station might be a private IP address, and the core network does not need to identify the routing of this address.

[0056] In this embodiment, in the LTE system, the home base station subsystem comprises a home base station and a home base station gateway, the local gateway module is the home base station gateway connecting to the home base station, and the core network management network element is a MME. The GTP-C channel is terminated at the home base station gateway, and the method requires that both the home base station and the home base station gateway support the GTP-C protocol. A stream control transmission protocol (SCTP) is used between the home base station and the home base station gateway for communication. This embodiment is typically applied in the case that the IP address used to set up a GTP channel by the home base station gateway is different from the SCTP connection address.

[0057] As shown in FIG. 8, the method for accessing the local network by the mobile terminal via the home base station comprises the following steps.

[0059] In the LTE home base station system, the registration procedure multiplexes the S1 setup procedure.

[0060] Step 802, the UE initiates a RRC connection setup request to the home base station.

[0061] Step 803, the home base station sends an initial UE message to the home base station gateway to trigger the Iu connection setup procedure.

[0062] Step 804, the home base station gateway receives the initial UE message, and the home base station gateway includes the IP address used to set up the GTP channel into the initial UE message and sends it to the MME.

[0063] Step 805, the UE initiates a PDN connection activation request to the MME, and the request carries the APN representing the local access.

[0064] Step 806, the MME receives the PDN connection activation request and determines that the UE needs to access the local network according to the APN.

[0065] Step 807, the MME sends a bearer setup request message to the home base station gateway; the message type is GTP-C, and the target address is the IP address used to set up the GTP channel by the home base station gateway, that is, the IP address received from the registration message of the home base station in step 801.

[0066] Step 808, the home base station gateway sends a bearer setup request to the home base station.

[0067] Step 809, the local GGSN bond to the home base station performs admission control to the mobile terminal user according to the identification of the mobile terminal user, such as an IMSI or an MSISDN; if the access is allowed, it performs the bearer setup proced, otherwise, a failure response is returned.

[0068] This step is optional.

[0069] Step 810, the HeNB performs the bearer setup procedure, such as functions that PDN-GW needs to perform, such as storing necessary information, allocating resource, assigning the IP address to the UE; and sends the GTP-C bearer setup response message to the MME.

[0070] Step 811, the HeNB GW receives the bearer setup response message, and forwards the message to the MME.

[0071] In the subsequent procedure, all GTP-C messages between the MME and the home base station are transmitted via two sections of GTP signaling which are the MME-HeNB GW and the HeNB GW-HeNB, and the procedure is not re-described here.

[0072] Step 812, the SGSN sends a PDP context activation accept message to the UE, the PDP context activation procedure ends, and the UE can access the local data network.

[0073] In the application scenarios of the above-mentioned third embodiment, if the IP address used to set up the GTP channel by the home base station gateway is the same as the address of the SCTP, there is no need to notify the IP address used to set up the GTP channel by the home base station gateway to the MME.

[0074] In the three above-mentioned embodiments, besides of the described method that the mobile terminal makes the core network management network element acquire that the mobile terminal needs to access the local network, by notifying the core network management network element of "access point representing the local access", other methods can be used to make the core network management network element know that the mobile terminal needs to access the local network, thus initiating and setting up a GPRS tunneling control bearer to the local gateway module, which are not re-described here.
