To this end, the following technical solutions of the embodiments of the present application are proposed.

Fig. 2 is a first schematic flow chart of a data updating method according to an embodiment of the present application, and as shown in fig. 2, the data updating method includes the following steps:

step 201: the terminal obtains EPLMN information from a server, wherein the EPLMN information comprises at least one PLMN information, and the EPLMN information can be updated on the server side.

In the embodiment of the application, the terminal can be any equipment capable of communicating with a network, such as a mobile phone, a tablet computer, a vehicle-mounted terminal and the like. The terminal may be an RUS-based system.

Referring to fig. 3, regardless of whether the terminal is in a roaming state, the embodiment of the present application maintains an EPLMN information on the server side, where the EPLMN information includes at least one PLMN information, and in an example, the EPLMN information maintained on the server side is stored in an EPLMN. The operator or other administrative personnel may dynamically configure server-side EPLMN information, such as: deleting a certain PLMN in the EPLMN information, adding a new PLMN in the EPLMN information, replacing a certain PLMN in the EPLMN information, and the like. Therefore, the EPLMN information can be updated on the server side, and an operator can flexibly and dynamically configure the EPLMN information.

In the embodiment of the application, when the EPLMN information is updated on the server side, the terminal acquires the updated EPLMN information from the server. For example: the terminal can automatically connect with the server under the WIFI/data network condition, current latest EPLMN information is obtained from the server, further, the terminal can monitor the broadcast message of the server, whether the EPLMN information is updated on the server side is determined based on the broadcast message, and if the EPLMN information is determined to be updated on the server side, the terminal automatically obtains the updated EPLMN information.

Referring to fig. 3, the terminal APP acquires updated EPLMN information from the server through the update module and stores the updated EPLMN information in the database update.db, the update.db periodically detects whether the updated EPLMN information is stored, and if the updated EPLMN information is not stored, the terminal APP returns to the server to acquire the updated EPLMN information. If the update EPLMN information is stored in the ROMUP DATE.DB, the terminal generates an EPLMN list corresponding to the terminal based on the EPLMN information and a PLMN corresponding to a subscriber identity card (such as a SIM or a USIM) of the terminal, wherein the EPLMN list comprises at least one PLMN information.

Step 202: and the terminal loads the EPLMN information, and the loaded EPLMN information is used for matching the target PLMN obtained by searching the network by using the PLMN information in the EPLMN information in the process of registering the terminal to the network.

In the embodiment of the present application, the terminal loads an EPLMN list corresponding to the terminal into a MODEM (MODEM).

Referring to fig. 3, the terminal writes the EPLMN list corresponding to the terminal into an EPLMN NV file, so that, in the process of registering the terminal with a network, the modem is used to search the network to obtain the target PLMN, and the target PLMN is matched with PLMN information in the EPLMN list.

According to the technical scheme, when the user roams abroad, the terminal can be automatically connected with the server under the WIFI/data network condition to obtain an updated EPLMN list, the EPLMN list is loaded to the MODEM network searching module and is effective immediately, and when the network is searched, the PLMNs in the EPLMN list are loaded to be the EPLMN, so that the problem of network searching abnormality of the mobile phone of the user is solved quickly, the user experience is improved, and the withdrawal probability and the complaint rate caused by abnormal registration are reduced.

Fig. 4 is a schematic flowchart of a second method for updating data according to an embodiment of the present application, and as shown in fig. 4, the method for updating data includes the following steps:

step 401: the roupdate module obtains updated EPLMN information from the server.

Step 402: the update module stores the updated EPLMN information in a database update.

Step 403: the carousel module determines whether the current carousel-db includes updated EPLMN information, if yes, step 404 is performed, and if no, step 401 is performed.

Step 404: and analyzing the EPLMN information to acquire all PLMN information.

Step 405: converting the PLMN information to a format of MCC + MNC.

Step 406: and storing the formats of the MCC + MNC corresponding to the PLMN information in an array.

Step 407: the array is loaded into the MODEM and the relevant information is recorded in the EPLMN NV.

Step 408: and prompting the updating to be completed.
