The embodiment relates to a terminal supporting mobile data service, and provides a terminal for APN adaptive selection operation when the terminal roams, and the system organization of the terminal can comprise: terminal, subscriber identity card (SIM card), APN list.
The network supported by the terminal may include, but is not limited to: 2G (2Generation, 2 nd Generation mobile communication technology), 3G, 4G, and the like.

The subscriber identity module card of the present patent includes but is not limited to the current mainstream subscriber identity modules cards such as: SIM card, USIM (Universal Subscriber Identity Module) card, UIM (User Identity Module) card, and the like.
A terminal for supporting mobile data network related service presets one or more groups of APNs, each group of APN corresponds to a network parameter of an operator, and an APN database is prestored in a terminal storage unit.
The roaming APN database stores APN data information corresponding to a roaming network, and the terminal reads and searches the database when roaming so as to find whether APN configuration data information corresponding to a roaming area network exists. The roaming APN database can be stored on the SIM card or in a terminal storage space, and corresponding configuration or operation can be carried out according to specific use conditions, wherein the specific configuration or operation comprises copying, deleting, moving and the like of APN entry data.
When the terminal judges that no roaming APN database exists in the inserted SIM card or no matched APN entry is found in the roaming APN database, the terminal can further search from the terminal storage space and perform corresponding configuration or operation according to the search result, wherein the specific configuration or operation comprises copying, deleting, moving and the like of APN entry data.
When the terminal judges that the terminal enters a roaming Network environment in the normal use process, the terminal extracts registered Network parameter information of a roaming place, wherein the registered Network parameter information comprises MCC (Mobile Country Code), MNC (Mobile Network Code) and other information of a Network of the roaming place, then the terminal reads a roaming APN database in a SIM card storage area, if the SIM card is read to have the roaming APN database, the terminal searches in the roaming APN database of the SIM card according to the MCC, MNC and other information of the roaming Network, if a matched APN entry is found, the APN entry parameter is used for trying to connect the Mobile Network, and if the connection is successful, the terminal uses a new APN entry as an internet access default parameter.
If the SIM card has no roaming APN database or has but does not search related APN entries, the terminal searches in the APN database of the terminal according to the information of MCC, MNC and the like of a roaming network, if the matched APN entries are found, the APN entry parameters are used for trying to connect the mobile network, and if the connection is successful, the terminal uses a new APN entry as an internet access default parameter. Meanwhile, the terminal can write the APN item into a roaming APN database on the SIM card.
Further, when the terminal finds a new matching APN in the roaming network and configures the APN as a default internet access APN of the terminal, the terminal can modify the network mode of the SIM card corresponding to the APN to achieve the purpose of internet access with optimal speed.
Further, the claims of this patent are directed to terminals, and the scope of protection includes, but is not limited to, terminals that support dual cards, and may also include multi-card terminals. When the terminal judges that the roaming APN databases exist in the multiple SIM cards of the terminal at the same time, the terminal can synchronize the roaming APN databases in the multiple SIM cards.
All the embodiments described below provide a method for supporting APN adaptive configuration operation when an intelligent terminal roams based on a terminal supporting high-speed mobile data network technology, and for increasingly perfect mobile 4G network technology, a method for storing and extracting a roaming APN database in an SIM card is implemented, and a method for automatically synchronizing and updating APN parameters is implemented, so as to improve the mobile internet user experience during roaming.
The fourth embodiment:
as shown in fig. 3, a schematic diagram of a system framework of the intelligent terminal supporting the dual 4G SIM card technology provided in this embodiment is shown in fig. 3, and it can be seen from fig. 3 that in this embodiment, a roaming APN database is established on the SIM card, and the roaming APN database can be synchronously updated with an APN entry in the terminal APN database according to a switching operation of a terminal roaming state.
Specifically, the roaming APN database stores APN data information corresponding to a roaming network, and the terminal reads and searches the database during roaming to find whether APN configuration data information corresponding to a roaming area network exists. The roaming APN database can be stored on the SIM card or in a terminal storage space, and corresponding configuration or operation can be carried out according to specific use conditions, wherein the specific configuration or operation comprises copying, deleting, moving and the like of APN entry data.
The search operation of the roaming APN database comprises the following steps: the terminal can search in the roaming APN database according to a certain rule, and if the configuration is successful after the search is successful, the terminal can be connected with and use the corresponding roaming network at the roaming location.
The roaming APN database is a database that stores parameters of a plurality of APNs, and the database can add, delete, copy or move APN entries therein, and the database can be stored in a storage space of the terminal or a SIM card or the terminal.
Fifth embodiment:
as shown in fig. 4, the roaming APN configuration operation method provided in this embodiment includes:
s401: when the terminal detects the registration to the roaming network, the MCC/MNC and other parameters of the roaming network are extracted.
S402: the terminal uses the MCC/MNC and other parameters of the roaming network as key parameters to search in the APN database in the terminal, and the searching sequence can be that firstly the SIM card storage space is used and then the terminal storage space is used.
S403: and if the terminal finds the effective APN parameter which can be accessed to the Internet, the terminal automatically configures the parameter as the default access APN parameter of the terminal.
S404: the terminal stores the APN parameter in a roaming APN database in the SIM card. And then when the user enters the roaming place again, after the terminal extracts the roaming APN stored by the SIM card, the effect of rapidly configuring the APN during roaming is realized.
In addition, another effect of storing the roaming APN on the SIM card is that after a user changes a mobile phone, the roaming APN database is not influenced, and the quick configuration is still effective.
Sixth embodiment:
as shown in fig. 5, the APN adaptive configuration operation method provided in this embodiment includes:
S501-S505: when the terminal judges that the terminal enters a roaming network environment in the normal use process, the terminal extracts registered network parameter information of a roaming place, including MCC, MNC and other information of the network of the roaming place, then reads a roaming APN database in a storage area of an SIM card, if the terminal reads that the SIM card has the roaming APN database, the terminal searches in the roaming APN database of the SIM card according to the MCC, MNC and other information of the roaming network, if a matched APN item is found, the APN item parameter is used for trying to connect the mobile network, and if the connection is successful, the terminal uses a new APN item as an internet access default parameter.
S506-S508: if the SIM card has no roaming APN database or has APN entries related to retrieval, the terminal further searches in the APN database of the terminal, if the matched APN entries are found, the APN entry parameters are used for trying to connect the mobile network, and if the connection is successful, the terminal uses the new APN entries as the default parameters for surfing the Internet. Meanwhile, the terminal can write the APN item into a roaming APN database on the SIM card.
Seventh embodiment:
this embodiment further illustrates the present invention by way of an example.
Figure 6 is a roaming APN database in an application. The intelligent terminal can be provided with an application program APP, and the application program can help a user to set APN or network mode switching rules when the mobile phone is roaming.
As shown in fig. 6, APN entry data information is preset in the database of the APP, and the information includes MCC, MNC, Networkmode, and the like. The specific parameters can be set or modified by the user, updated by the terminal in use, and acquired and updated from the network.
Fig. 7 is a flowchart illustrating an operation of configuring an APN by an application when the terminal roams in this embodiment. As can be seen from fig. 7, the APN implementing method provided in this embodiment includes:
s701: an application program is installed in the mobile phone, so that the APN parameters and the network mode of the mobile phone for surfing the Internet can be automatically switched when the mobile phone is in roaming.
S702-S705: let us assume that the user has already performed parameter setting of the relevant roaming place, and when the mobile phone detects that a roaming network is registered, the mobile phone extracts MCC and MNC of the registered roaming place network, and the application program uses the parameter to look up the corresponding APN entry in the database. If the data is not found, the operation is ended; and if the matched APN item is found, the application program of the mobile phone configures the found APN item as a default configuration parameter of the mobile phone for surfing the Internet. And simultaneously switching the network mode to the mode corresponding to the APN entry. The operation is ended. And then when the mobile phone detects that the mobile phone enters a new roaming network or returns to a non-roaming local network, the mobile phone selects to search the APN again or restore the APN to a previous non-roaming configuration state according to specific conditions.
The embodiment provides a method for configuring an APN during terminal roaming based on a 4G mobile network, and aims at the increasingly sophisticated 4G mobile terminal technology, so that synchronous operation of a roaming APN database between an SIM card and a terminal can be performed in a terminal system, thereby facilitating sharing of the APN in different storage areas in the terminal and achieving the purpose of fast internet access of the terminal.
