Description

Technical Field



[0001] The present disclosure relates to the field of communication technology.

Background



[0002] With the rapid development and construction of 5th Generation Mobile Networks (5G) technologies, terminals supporting the 5G technologies rapidly increase in recent years. Access Point Name (APN) refers to a network access technology, which is a parameter that needs to be configured when a terminal accesses a network, and determines an access manner used by the terminal to access the network. A terminal can access a wireless data network operated by a telecommunication operator (referred to as operator hereinafter) only after an APN parameter is correctly configured on the terminal, and the APN configuration information corresponding to different operators is different. In a 4th Generation Mobile Communication Technology (4G) network, an APN of an Internet type is unique, and there are few terminals currently supporting the 5G technologies, therefore operators configure an APN dedicated for a 5G network for terminals supporting the 5G technologies, so that terminals, supporting the 5G technologies, of a specific machine type or a specific batch can use the APN dedicated for the 5G network for network access to the 5G network. However, at present, the 5G network is in the early stage of construction, and it is difficult for operators to take full consideration of the influence of the formulation of the new APN dedicated for the 5G network on the existing terminals not supporting the 5G technologies in the process of using the mobile data network, thus resulting in the problem that the mobile terminals not supporting the 5G technologies have an abnormal network access in the case that both the APN used in a 5G network and the APN used in a non-5G network exist.

[0003] The above contents are only used for assisting in understanding the technical solutions of the present disclosure, and do not represent an admission that the above contents are prior art.

[0009] Fig. 1 is a schematic structural diagram of a hardware running environment of an APN configuration method according to at least one embodiment of the present disclosure.

The processor 1001 may be configured to invoke the network operation control program stored in the memory 1005, and execute the following operations: determining an APN category of an candidate APN, wherein the APN category of the candidate APN includes an APN used in a 5G network or an APN used in a non-5G network; determining, according to a configuration parameter of the terminal, a network mode of the terminal, wherein the network mode includes a network mode supporting the 5G network or a network mode not supporting the 5G network; and determining whether to execute network access based on the candidate APN according to whether the APN category matches the network mode.

[0017] According to the embodiments provided in the present disclosure, before determining the APN category of the candidate APN, the processor 1001 may invoke the network operation control program stored in the memory 1005 to further perform the following operations: determining, based on parameter information of the candidate APN, that an APN type of the candidate APN is a network type. The parameter information of the candidate APN includes operator identifier information, a Mobile Country Code (MCC), a Mobile Network Code (MNC) and/or the APN type. The APN type includes the network type or a multimedia message type.

[0018] According to the embodiments provided in the present disclosure, before determining that the APN type of the candidate APN is the network type, the processor 1001 may invoke the network operation control program stored in the memory 1005 to further perform the following operations: sending the parameter information of the candidate APN to a network side so that the network side determines that the candidate APN is valid; and determining that the candidate APN is valid based on information fed back by the network side and indicating that the candidate APN is valid.

[0019] According to the embodiments provided in the present disclosure, before determining the APN category of the candidate APN, the processor 1001 may invoke the network operation control program stored in the memory 1005 to further perform the following operations: reading a subscriber identity card to obtain the operator identifier information, the MCC and the MNC; and looking up, according to the operator identifier information, the MCC and the MNC, in an APN database to obtain a corresponding APN list. The APN list at least includes the candidate APN, and correspondingly stores the candidate APN and the parameter information of the candidate APN.

[0020] According to the embodiments provided in the present disclosure, after obtaining the APN list and before determining the APN category of the candidate APN, the processor 1001 may invoke the network operation control program stored in the memory 1005 to further perform the following operations: determining that the number of APNs, that are valid and whose APN type is the network type, in the APN list is greater than 1.

[0021] According to the embodiments provided in the present disclosure, the processor 1001 may invoke the network operation control program stored in the memory 1005 to further perform the following operations: in response to determining that the APN category of the candidate APN is the APN used in the 5G network and the network mode is a network mode not supporting the 5G network, not executing the network access based on the candidate APN.

[0022] According to the embodiments provided in the present disclosure, the configuration parameter of the terminal may include at least one of: a network mode setting parameter, a model type parameter, and an International Mobile Equipment Identity (IMEI).

[0023] The embodiments of the present disclosure also provide an APN configuration method. As shown in Fig. 2, which is a schematic flowchart of the APN configuration method provided in at least one embodiment of the present disclosure, the method may include operation S21 to operation S23.

[0024] In operation S21, a terminal determines an APN category of a candidate APN, wherein the APN category of the candidate APN includes an APN used in a 5G network or an APN used in a non-5G network.

[0025] According to the embodiments provided in the present disclosure, the operation that the terminal determines the APN category of the candidate APN may include: the terminal tests, based on the candidate APN, an average network speed of a network corresponding to the candidate APN; and in response to determining that the average network speed is not less than a set network speed threshold, the terminal determines that the candidate APN is the APN used in the 5G network, and in response to determining that the average network speed is less than the set network speed threshold, the terminal determines that the candidate APN is the APN used in the non-5G network.

[0026] According to the embodiments provided in the present disclosure, before the terminal determines the APN category of the candidate APN, the method may further include: the terminal determines, based on parameter information of the candidate APN, that an APN type of the candidate APN is a network type. The parameter information of the candidate APN may include operator identifier information, MCC, MNC, and/or the APN type. The APN type includes a network type or a multimedia message type.

[0027] According to the embodiments provided in the present disclosure, before the terminal determines that the APN type of the candidate APN is the network type, the method may further include: the terminal sends the parameter information of the candidate APN to a network side so that the network side determines that the candidate APN is valid; and the terminal determines that the candidate APN is valid based on information fed back by the network side and indicating that the candidate APN is valid.

[0028] In operation S22, the terminal determines a network mode of the terminal according to a configuration parameter of the terminal, wherein the network mode includes a network mode supporting the 5G network or a network mode not supporting the 5G network.

[0029] According to the embodiments provided by the present disclosure, the configuration parameter of the terminal may include at least one of: a network mode setting parameter, a model type parameter, and an IMEI.

[0030] In operation S23, the terminal determines, according to whether the APN category matches the network mode, whether to execute network access based on the candidate APN.

[0031] According to the embodiments provided in the present disclosure, the operation that the terminal determines, according to whether the APN category matches the network mode, whether to perform the network access based on the candidate APN may include: in response to determining that the APN category of the candidate APN is the APN used in the 5G network and the network mode is a network mode not supporting the 5G network, the terminal does not execute the network access based on the candidate APN; in response to determining that the APN category of the candidate APN is the APN used in the 5G network and the network mode is a network mode supporting the 5G network, the terminal may execute the network access based on the candidate APN, or the terminal may not execute the network access based on the candidate APN; in response to determining that the APN category of the candidate APN is the APN used in the non-5G network, the terminal may execute the network access based on the candidate APN, or the terminal may not execute the network access based on the candidate APN.

[0032] According to the embodiments provided by the present disclosure, before operation S21, the method may further include: the terminal reads a preset identification parameter in a subscriber identity card, and looks up, according to a preset mapping relation, in an APN database to obtain an APN list corresponding to the preset identification parameter.

[0033] According to at least one embodiment of the present disclosure, the preset identification parameter in the subscriber identity card may include at least one of: operator identifier information, an MCC and an MNC.

[0034] According to the embodiments provided in the present disclosure, the APN list at least includes the candidate APN, and correspondingly stores the candidate APN and the parameter information of the candidate APN.

[0035] According to the embodiments provided in the present disclosure, after the terminal obtains the APN list and before the terminal determines the APN category of the candidate APN, the method may further include: the terminal determines that the number of APNs, that are valid and whose APN type is the network type, in the APN list is greater than 1.

[0036] At present, the 5G network is in the early stage of construction, and it is difficult for operators to take full consideration of the influence of the formulation of the new APN dedicated for the 5G network on the existing terminals not supporting the 5G technologies in the process of using the mobile data network, thus resulting in the problem that the mobile terminals not supporting the 5G technologies use the APN dedicated for the 5G network in the case that both the APN used in a 5G network and the APN used in a non-5G network exist.

[0037] For example, an operator formulates an APN parameter dedicated for a 5G network, and an IMEI number segment is allocated to a small amount of 5G terminals to support a 5G function. If a terminal not supporting the 5G function uses the APN dedicated for the 5G network to perform network registration, the network access function will be abnormal.

[0038] In order to solve the problem, the APN configuration method provided in the embodiments of the present disclosure can obtain an APN list according to a preset identification parameter, and can determine an APN category of each candidate APN in the APN list, i.e., determine whether each candidate APN is an APN used in a 5G network or an APN used in a non-5G network. Further, the terminal can determine a network mode of the terminal according to a configuration parameter of the terminal, i.e., determine whether the terminal supports a 5G network or does not support the 5G network. In this way, the terminal can additionally refer to the above pre-judgment information when determining which APN, i.e., an APN used in a 5G network or an APN used in a non-5G network, to use for network connection, thereby reducing the possibility that the terminal which does not support 5G mistakenly uses the APN dedicated for the 5G network.

[0039] According to the embodiments provided in the present disclosure, the APN used in the 5G network may be set as a non-configurable APN, so that the terminal can exclude the APN used in the 5G network, thereby enabling the configuration method to be suitable for the terminal not supporting the 5G to perform an effective network connection operation in various networking scenarios, and improving the user experience.

[0040] According to the embodiments provided in the present disclosure, the APN configuration method may be applied to an APN configuration system. The APN configuration system may include a terminal, an APN database and a subscriber identity card. When a user triggers a network access instruction, the terminal receives the network access instruction, confirms a subscriber identity card for performing a network connection operation in the terminal, and reads a preset identification parameter in the subscriber identity card. The subscriber identity card may be a Subscriber Identity Module (SIM) card, a Universal Subscriber Identity Module (UISM) card, or a User Identity Model (UIM) card. The preset identification parameter may include at least an MCC and an MNC. The terminal looks up, according to a preset mapping relationship, in the APN database in the terminal to obtain an APN list corresponding to the preset identification parameter in the subscriber identity card. The preset mapping relationship may be name information and type information of one or more APNs corresponding to a combination of one MCC and one MNC. The APN list may contain information including name information, type information, an operator name, and the like of the APN which are associatively stored.

[0041] For example, in one exemplary implementation, the terminal reads the SIM card to obtain that the MCC is 825 (i.e., the MCC of China), and that the MNC is 02 (i.e., the MNC for the operator China Mobile). According to the preset mapping relationship, three APNs corresponding to the MCC of 02 and the MNC of 825 are found in an APN database stored in the terminal, the names of the three APNs are omiga_5G, omiga and omiga_mms respectively, and the APN types respectively corresponding to the three APNs are default (i.e., a mobile network type which supports network connection by default, that is, the APN type is a network type), default supl (i.e., a mobile network type which supports network connection by default and supports A-GPS customization, that is, the APN type is a network type), and mms (i.e., the APN type is a multimedia message type).

[0042] According to the embodiments provided by the present disclosure, the terminal may obtain a configuration parameter of the terminal, so as to determine whether the network mode of the terminal is a network mode supporting 5G. The configuration parameter of the terminal may be an IMEI number segment of the terminal, network mode configuration information of the terminal, a chip type, model information, or the like. For example, the terminal may find out, by obtaining the model information of the terminal, the network type that is supported by the model, so as to determine whether the terminal supports the 5G network mode.

[0043] According to the embodiments provided by the present disclosure, if the network mode of the terminal is a network mode not supporting the 5G network, then the terminal determines, through a preset rule, an APN whose APN category is the APN used in the 5G network among all the candidate APNs.

[0044] According to the embodiments provided by the present disclosure, the preset rule may be determining that the APN category of the candidate APN is the APN used in the 5G network when a 5G keyword exists in name information of the candidate APN. Alternatively, a mobile network capability reference value of a candidate APN may be obtained, and whether the APN category of the candidate APN is an APN used in the 5G network is determined based on an average network speed reference value in the mobile network capability reference value. For example, if the average network speed reference value falls within the speed range of a 5G network, it is determined that the APN category of the candidate APN is the APN used in the 5G network; and if the average network speed reference value does not fall within the speed range of the 5G network, it is determined that the APN category of the candidate APN is the APN used in a non-5G network.

[0045] According to the embodiments provided by the present disclosure, name information of a plurality of APNs found in the APN list according to the preset mapping relationship may be referred to as an APN name information group. The mobile network capability reference value is a network connection capability reference value or an average network speed reference value obtained by the terminal by performing a polling operation on a plurality of APNs in the APN list. Before determining the APN used in the 5G network, the terminal may firstly determine whether an APN used in the 5G network exists in the APN list. For example, the terminal may determine whether an APN used in the 5G network exists in the APN list based on the 5G keyword in the APN name information group or the APN category of each APN.

[0046] According to the embodiments provided by the present disclosure, after determining that the APN category of the candidate APN is the APN used in the 5G network and the network mode of the terminal is a network mode not supporting the 5G network, the terminal may further set the candidate APN as a non-configurable APN. When selecting an APN to connect to the network, the terminal will not select this candidate APN. The terminal may add a non-configurable name identifier character into a name field of the candidate APN, and list the APN having the non-configurable name identifier character into a non-configurable APN list; or after receiving APN error information, the APN is added into the non-configurable APN list and the APN error information is sent to the terminal when determining that an APN used in a 5G network exists in the candidate APNs.

[0047] According to the APN configuration method provided in the embodiments of the present disclosure, a preset identification parameter in a subscriber identity card may be read, and an APN list corresponding to the preset identification parameter can be found in an APN database according to a preset mapping relationship; a configuration parameter of a terminal may be obtained, and whether the network mode of the terminal is a network mode supporting 5G may be determined, based on the configuration parameter; if the network mode of the terminal is a network mode not supporting the 5G network, the terminal does not use the APN whose APN category is the APN used in the 5G network to execute network access, and the APN used in the 5G network may be set as a non-configurable APN. By means of the method, the possibility that a terminal not supporting 5G mistakenly uses an APN used in the 5G network is reduced. In addition, an APN used in the 5G network is set to be a non-configurable APN, based on which the terminal excludes the APN used in the 5G network, so that the configuration method is applicable for a terminal not supporting the 5G to perform an effective network connection operation in various networking scenarios, thereby improving the user experience, and solving the problem that a terminal not supporting the 5G has an abnormal network access in the case where the APN used in 5G and other APNs simultaneously exist.

[0048] As shown in Fig. 3, which is another schematic flowchart of an APN configuration method provided in the embodiments of the present disclosure. The operation S23 may include operation S31-operation S33.

[0049] In operation S31, if the network mode of the terminal is a network mode not supporting the 5G network, then name information corresponding to each APN in the APN list is obtained.

[0050] In operation S32, it is determined whether a 5G keyword exists in the plurality of pieces of name information.

[0051] According to the embodiments provided in the present disclosure, if it is judged, based on parameters such as terminal type information and chip type, that the terminal does not support the 5G network mode, then the terminal obtains a group of name information of multiple APNs from the obtained APN list, and checks whether there is a 5G keyword in the name information group.

[0052] In operation S33, if there is a 5G keyword in the plurality of pieces of name information, an APN whose APN category is an APN used in the 5G network is determined from the APN list according to the 5G keyword.

[0053] According to the embodiments provided by the present disclosure, if the terminal finds the 5G keyword in the obtained name information group, the terminal may directly determine that the candidate APN corresponding to this 5G keyword is the APN used in the 5G network according to the 5G keyword. For example, if the terminal obtains a name information group including three pieces of APN name information, i.e., omiga_5G, omiga, and omiga_mms, and finds that the omiga_5G in the three pieces of name information has a 5G keyword, the terminal directly determines the candidate APN named omiga_5G as the APN used in the 5G network.

[0054] According to the embodiments provided by the present disclosure, as shown in Fig. 3, after operation S33, the method may further include operation S50 and operation S60.

[0055] In operation S50, one APN is determined as a first target APN in the APN list excluding non-configurable APN (i.e., the APN whose APN category is the APN used in the 5G network).

[0056] In operation S60, an APN parameter configuration is performed on the terminal according to the first target APN, so that the terminal accesses a first target network based on the first target APN.

[0057] According to the embodiments provided by the present disclosure, after excluding the APN used in the 5G network from the APN list, the terminal with the network mode not supporting the 5G network determines one APN from the remaining APNs of the network type, and uses this APN as the first target APN. The terminal connects to a corresponding first target network based on the first target APN. The first target APN refers to one APN selected from an APN list excluding the APN used in the 5G network in a case where the terminal does not support the 5G network mode, and the first target APN is the mobile data network corresponding to the first target APN. For example, if the determined first target network is a 4G network with an APN of omiga, then the terminal connects to the corresponding 4G network based on this APN.

[0058] According to the APN configuration method provided in the embodiments of the present disclosure, if the network mode of the terminal is a network mode not supporting the 5G network, name information corresponding to each APN in an APN list is obtained, and it is determined whether a 5G keyword exists in the obtained name information. If the obtained name information includes a 5G keyword, an APN whose APN category is an APN used in the 5G network is determined in the APN list according to the 5G keyword. One APN is determined in the APN list excluding non-configurable APN as a first target APN. APN parameter configuration is performed on the terminal according to the first target APN, so that the terminal accesses a first target network based on the first target APN. By judging whether a 5G keyword exists in name information of an APN of a network type, a terminal can directly judge whether the corresponding APN is an APN used in the 5G network according to the 5G keyword, thereby omitting intermediate judgment operations and improving the network connection efficiency. By selecting one APN from the APNs of the network type excluding the APN used in a 5G network to perform a mobile network connection, abnormal situations caused by a terminal not supporting the 5G mistakenly using the APN used in the 5G network to perform network connection are avoided, and the user experience is improved.

[0059] Fig. 4 is still another schematic flowchart of an APN configuration method according to at least one embodiment of the present disclosure. After operation S32, the method may further include operation S34 and operation S35.

[0060] In operation S34, if there is no 5G keyword in the plurality of pieces of name information, the number of APNs, of which the APN type is the network type and which contain a default network connection keyword, in the APN list is obtained, and it is determined whether the number of APNs of the network type is equal to 1 or greater than 1.

[0061] In operation S35, if the number of APNs of the network type is greater than 1, a polling operation is performed on the APNs of the network type in the APN list, mobile network capability reference values of the APNs of the network type are obtained, and APN categories of the APNs of the network type are determined according to the mobile network capability reference values of the APNs of the network type.

[0062] According to the embodiments provided by the present disclosure, if the terminal does not find the 5G keyword in the above plurality of pieces of name information, then the terminal obtains an APN type information group corresponding to the above plurality of pieces of name information from the obtained APN list. The terminal searches for a default network connection keyword in the APN type information group, and takes a candidate APN corresponding to the type information containing the default network connection keyword as an APN of a network type. The default network connection keyword being default represents an APN of a default network connection type, which is used for accessing a mobile network of the Internet type. That is, the APN type being a network type refers to that the APN can access the mobile network of the Internet type. The terminal judges whether the corresponding number of the APNs of the network type is equal to 1 according to the number of pieces of type information containing the keyword 'default'. If the APN containing the keyword 'default' is not unique, that is, if the number of APNs of the network-type is greater than 1, the terminal performs a polling operation on the APNs of the network type, so as to obtain a mobile network capability reference value of each APN of the network type. The mobile network capability reference value includes a network access capability reference value, an average Network speed, and the like. The terminal determines the APN category of each APN of the network type after obtaining the mobile network capability reference value of each APN of the network type. It should be noted that, among the APN types except the APN used in the 5G network, only the APN type corresponding to the APN used in the 4G network includes the keyword 'default'. After the type of the APN used in the 5G network is also set to include the keyword 'default', if two pieces of type information including the keyword 'default' appear in the corresponding APN type information in the APNs of the same operator in the same country, it can be determined that the APN must be an APN used in the 5G network.

[0063] According to the embodiments of the present disclosure, in order to obtain the network access capability reference value of each APN of the network type, the terminal sets a timer and performs a polling operation on the APNs of the network type. The terminal reports parameter information corresponding to the APN of the network type which enters the polling state to the mobile network in each polling period, and determines the network access capability reference value corresponding to each APN of the network type according to the return value from the network.

[0064] According to the embodiments provided in the present disclosure, in order to obtain an average network speed reference value of the APNs of the network type, in a designated or conditionally determined idle period, the terminal performs operations, such as network connection and network data packet transmission, based on the APNs of the network type, and calculates a maximum average transmission data network speed value corresponding to each APN of the network type, including but not limited to an uploading and downloading network speed value. An exemplary calculation method is provided herein. For example, a terminal downloads or uploads data packets from/to a fixed network address link, and calculates the size of the data packet transmitted within a unit time; or the terminal reads a dynamic change or historical value of the size of the data packet in the fixed network address link. The terminal determines a standard category determination interval for determining the APN category according to conditions such as a transmission rate protocol requirement specified in 5G or 4G related protocols for mobile data packets. For example, since the APN named omiga_5g of the network type corresponds to a network speed of 1000M, and this network speed falls in the standard category determination interval of the 5G network mode according to the protocol, the APN category of the APN can be determined as the APN used in the 5G network.

[0065] According to the APN configuration method provided in the embodiments of the present disclosure, if there is no 5G keyword in a plurality of pieces of name information, the number of APNs, which contain the default network connection keyword and of which the APN type is the network type, in an APN list is obtained, and it is determined whether the number of the APNs of the network type is equal to 1 or greater than 1; if the number of the APNs of the network type is greater than 1, a polling operation is performed on the APNs of the network type in the APN list, a mobile network capability reference value of each APN of the network type is obtained, and the APN used in the 5G network is determined from the APNs of the network type according to their respective mobile network capability reference values. By means of judging the APN type information of a candidate APN whose name information does not contain a 5G keyword, and when there are APNs of the 4G network and the 5G network, a polling operation is performed on the APNs of the 4G network and the 5G network to obtain APN category information of each APN, so that when there is no 5G keyword, a terminal can also determine and exclude the APN used in a 5G network, thereby reducing the possibility of using the APN used in a 5G network by mistake for a terminal which does not support 5G. In addition, by selecting one APN from the APNs of the network type excluding the APN used in the 5G network to perform a mobile network connection, abnormal situations caused by a terminal not supporting the 5G mistakenly using the APN used in the 5G network to perform network connection are avoided, and user experience is improved.

[0066] According to the embodiments of the present disclosure, after the terminal determines the network mode of the terminal according to the configuration parameter of the terminal in operation S22, the method may further include operations a-f.

[0067] In operation a, if the network mode of the terminal is a network mode supporting a 5G network, the number of APNs, which contain a default network connection keyword and of which the APN type is the network type, in the APN list is obtained, and it is determined whether the number of APNs of the network type is equal to 1 or greater than 1.

[0068] In operation b, if the number of APNs of the network type is equal to 1, proceeding to operation c; otherwise, proceeding to operation d.

[0069] In operation c, the only APN which contains a default network connection keyword is determined as a second target APN, and APN parameter configuration is performed on the terminal according to the second target APN, so that the terminal connects to a second target network based on the second target APN.

[0070] According to the embodiments provided by the present disclosure, if it is judged, based on information such as the model information, that the network mode of the terminal is a network mode supporting the 5G network, the terminal obtains a type information group of respective APNs in the APN list, and looks up in the type information group for the type information containing a default network connection keyword 'default'. The terminal determines the APN corresponding to the type information containing the default network connection keyword 'default' as the APN of the network type, and determines whether the number of the APNs of the network type is equal to 1 or greater than 1. If the number of the APNs of the network type is equal to 1, then the terminal takes this unique APN of the network type as the second target APN, and connects to the corresponding second target network based on the configuration parameter of the second target APN. In the embodiments, the second target APN refers to the only APN in the case where the terminal supports the 5G network mode and there is only one APN that can be used for network connection, and the second target network is the mobile data network corresponding to this APN.

[0071] In operation d, the APNs of the network type are polled, and the mobile network capability reference values of the APNs of the network type are obtained.

[0072] In operation e, an APN of the network type with the fastest network speed is determined as a third target APN according to a network access capability reference value or an average network speed in the mobile network capability reference value of each APN of the network type.

[0073] In operation f, APN parameter configuration is performed on the terminal according to the third target APN, so that the terminal connects to the third target network based on the third target APN.

[0074] According to the embodiments provided in the present disclosure, if the number of APNs of the network type is greater than 1, that is, there are a plurality of APNs that can be used for network connection, the terminal performs a polling operation on the plurality of APNs of the network type, obtains a mobile network capability reference value, such as a network access capability reference value and an average network speed reference value, of each APN of the network type, and determines, according to the mobile network capability reference value of each APN of the network type, the APN with the fastest network speed in a current networking environment. The terminal takes this APN as a third target APN, performs parameter configuration based on the third target APN, and connects to a third target network corresponding to the third target parameter. The third target APN refers to an APN which has the fastest network speed in the current networking environment in the case that the terminal supports the 5G network mode and the APN that can be used for network connection is not unique, and the third target APN is the mobile data network corresponding to this APN.

[0075] According to the embodiments of the present disclosure, the APN configuration method may further include operation g and operation h.

[0076] In operation g, in response to determining that the network mode of the terminal is a network mode not supporting the 5G network, an APN whose APN category is the APN used in the 5G network is determined in the APN list.

[0077] In operation h, a non-configurable indication field is added in the name information corresponding to the APN whose APN category is the APN used in the 5G network , so as to set this APN used in the 5G network as a non-configurable APN.

[0078] According to the embodiments provided in the present disclosure, a terminal determines, in the APN list, an APN used in the 5G network according to obtained APN category information of each APN. In the case where a terminal does not support a 5G network, the terminal adds, in the APN list, an indication field indicating that the APN is an APN of the 5G network in name information corresponding to the APN used in the 5G network, so that the terminal directly determines and excludes the APN used in the 5G network according to the name information.

[0079] According to the APN configuration method provided in the embodiments of the present disclosure, if the network mode of the terminal is a network mode supporting 5G, the number of APNs, which contain a default network connection keyword and of which the APN type is the network type, in an APN list is obtained, and it is determined whether the number of APNs of the network type is equal to 1 or greater than 1; if the number of the APNs of the network type is equal to 1, this APN containing the default network connection keyword is determined as a second target APN, and APN parameter configuration is performed on the terminal according to the second target APN, so that the terminal connects to the second target network based on the second target APN. If the number of the APNs of the network type is greater than 1, a polling operation is performed on the APNs of the network type, and a mobile network capability reference value of each APN of the network type is obtained; according to a network access capability reference value or an average network speed in the mobile network capability reference value of each APN of the network type, an APN of the network type with the fastest network speed is determined as a third target APN, and APN parameter configuration is performed on the terminal according to the third target APN, so that the terminal connects to the third target network based on the third target APN. In the case where it is determined that the network mode of the terminal is a network mode not supporting the 5G network, an APN used in the 5G network is determined in an APN list, and a non-configurable indication field is added in name information of the APN used in the 5G network so as to set the APN used in the 5G network as a non-configurable APN. By means of the method, in the case where a terminal can support a 5G network mode, it is determined whether the APN of the network type is unique, and when the APN of the network type is unique, the terminal directly uses this APN as a target APN, thereby simplifying the operation of determining the target APN by the terminal, and improving the user experience at the same time. When the APN of the network type is not unique, a polling operation is performed to select an APN with the fastest network speed from the APNs of the network type to perform network connection, thereby improving the network connection quality and improving the user experience at the same time. In the case where a terminal does not support a 5G network mode, a non-configurable indication field is added to name information corresponding to an APN which has been determined as an APN used in the 5G network, so that it is not necessary for the terminal to judge this APN in a subsequent network connection process, thereby improving the network connection efficiency.
