Fig. 2 is a flowchart illustrating a PPLMN list adjustment method according to an embodiment of the present invention, where the method is applied to the mobile terminal and executed by the mobile terminal, and as shown in fig. 2, the method includes the following steps:
at step 202, a roaming destination planned by the user is determined.
Since the action of planning the roaming destination by the user usually occurs before the user reaches the roaming destination, in this embodiment, the mobile terminal does not reach the roaming destination when determining the roaming destination planned by the user.
The method comprises the steps that when the mobile terminal determines to obtain a roaming destination planned by a user, the mobile terminal can be located in a home place or a first roaming place, if the mobile terminal is located in the home place, the roaming destination planned by the user is determined, then the position of the mobile terminal is changed from the home place to the roaming destination according to the plan of the user, if the mobile terminal is located in the first roaming place, the position of the mobile terminal is determined to be changed from the first roaming place to the roaming destination according to the plan of the user, and if the mobile terminal is located in the first roaming place, the position of the mobile terminal is changed from the first roaming place to the roaming destination according to the plan of the user, wherein the first roaming place and the roaming destination are different roaming places of the mobile terminal.
After the roaming destination planned by the user is determined, before the mobile terminal reaches the roaming destination, the mobile terminal adjusts the PPLMN list according to the roaming destination, specifically, the currently used PPLMN list can be adjusted, and the adjusted PPLMN list contains the identifications of all PLMNs signed by the mobile terminal and the roaming destination.
In the PPLMN list adjusting method in the embodiment of the invention, the mobile terminal determines the roaming destination planned by the user, the PPLMN list of the mobile terminal is adjusted according to the roaming destination, and the adjusted PPLMN list comprises the identifications of all PLMNs signed by the mobile terminal and the roaming destination. By the PPLMN list adjusting method in the embodiment of the invention, the mobile terminal can dynamically adjust the PPLMN list of the mobile terminal according to the roaming destination planned by the user, so that the mobile terminal searches for the network through the identifiers of all PLMNs signed with the roaming destination, the network searching time of the mobile terminal at the roaming destination is reduced, the network searching efficiency and the network access efficiency are improved, and the technical problems of long network searching time consumption and low network searching efficiency when the mobile terminal searches for the network through the conventional PPLMN list are solved.
In the step 202, the roaming destination planned by the user may be determined in any one of the following manners (1) and (2):
the method comprises the steps that (1) a schedule plan of which the starting time is not reached is obtained from a mobile terminal, and if the destination of the schedule plan is a roaming place, the destination of the schedule plan is determined as a roaming destination planned by a user;
in the method (2), a roaming package that has not reached the use time is determined from the mobile terminal, and a roaming destination corresponding to the roaming package is determined as a roaming destination planned by the user.
In the method (1), the mobile terminal reads the content stored in the mobile terminal, and acquires a schedule plan which does not reach the starting time, wherein the schedule plan comprises one or more items of a travel plan, a train ticket purchase record, an airplane ticket purchase record and a hotel reservation record, the mobile terminal reads a destination of the schedule plan, and if the destination is a region outside a home region of the mobile terminal, namely a roaming region of the mobile terminal, the destination is determined as a roaming destination planned by the user. Since the mobile terminal acquires the schedule that has not reached the start time, the user should not reach the destination in the schedule, thereby ensuring that the mobile terminal determines the roaming destination planned by the user before the user reaches the planned roaming destination.
In the method (2), the mobile terminal reads the content stored in the mobile terminal, determines a roaming package that has not reached the use time, where the roaming package includes a roaming traffic packet and/or a roaming call packet, and determines a roaming place corresponding to the roaming package, and determines the roaming place corresponding to the roaming package as a roaming destination planned by the user. Since the mobile terminal determines that the roaming package has not reached the use time, the user should not reach the roaming place corresponding to the roaming package, so as to ensure that the mobile terminal determines the roaming destination planned by the user before the user reaches the planned roaming destination.
In this embodiment, by means of the above-mentioned manner (1) and manner (2), the roaming destination planned by the user can be determined before the user reaches the planned roaming destination, so that the mobile terminal can immediately use the PPLMN list matched with the roaming destination to perform network entry registration after the user reaches the roaming destination.
In this embodiment, by means of the above-mentioned manner (1) and manner (2), the roaming destination planned by the user can be determined without the user knowing, so that the user experience of the mobile terminal is not affected.
In other embodiments of the present invention, the mobile terminal may provide a roaming information input interface to the user, where the user enters the planned roaming destination, and the mobile terminal receives the roaming destination entered by the user. In the embodiment, the roaming destination is determined by adopting a mode of active input of the user, so that the accuracy of determining the roaming destination can be ensured.
In step 204, the mobile terminal adjusts the PPLMN list of the mobile terminal according to the roaming destination, which specifically includes: acquiring a PLMN list signed by the mobile terminal and the roaming destination, wherein the PLMN list comprises identifications of all PLMNs signed by the mobile terminal and the roaming destination, and replacing the PLMN list with a currently used PPLMN list. The identity of the PLMN may be an ID (identity) of the PLMN.
Wherein the mobile terminal may obtain the PLMN list subscribed to the roaming destination from the home or the server. The method for acquiring the PLMN list signed with the roaming destination by the mobile terminal from the server specifically includes: the mobile terminal sends a PLMN acquisition request to the server, the PLMN acquisition request is used for requesting to acquire a PLMN list which is signed with a roaming destination by the mobile terminal, the mobile terminal receives the PLMN list which is returned by the server in response to the PLMN acquisition request, and the PLMN list which is returned by the server is used as the PLMN list which is signed with the roaming destination by the mobile terminal. The server may be a server of a manufacturer of the mobile terminal, a server of an operator of the mobile terminal, a third-party server that has entered into a cooperative agreement with the mobile terminal and the operator thereof, or the like.
Specifically, the method for acquiring, by the mobile terminal, the PLMN list corresponding to the roaming destination from the home includes: the mobile terminal searches the identifiers of all PLMNs signed with the roaming destination by the mobile terminal in a PLMN list stored locally, and generates the PLMN list signed with the roaming destination by the mobile terminal according to the identifiers of all PLMNs signed with the roaming destination by the mobile terminal. In this method, the mobile terminal locally stores a PLMN list, which may be sent to the mobile terminal in advance by the server, and the mobile terminal stores in a memory, where the list may include all PLMN identifiers subscribed by the mobile terminal with all countries and regions around the world, and after determining the roaming destination, the mobile terminal searches for all PLMN identifiers subscribed by the mobile terminal with the roaming destination from the prestored PLMN list, and generates a PLMN list subscribed by the mobile terminal with the roaming destination according to all PLMN identifiers subscribed by the mobile terminal with the roaming destination.
In this embodiment, when the storage space of the mobile terminal is small, the mobile terminal may communicate with the server to obtain the PLMN list signed by the mobile terminal and the roaming destination, and when the mobile terminal has a large storage space, the mobile terminal may pre-store the PLMN list including all PLMN identifiers signed by the mobile terminal and all countries and regions around the world, so that the mobile terminal can rapidly obtain the PLMN list signed by the mobile terminal and the roaming destination without communicating with the server.
In the embodiment of the invention, the mobile terminal can acquire the PLMN list signed by the mobile terminal and the roaming destination from the server or the local, thereby providing a plurality of modes for acquiring the PLMN list for the mobile terminal, and the mobile terminal can acquire the PLMN list signed by the mobile terminal and the roaming destination in a proper mode under different scenes.
In the embodiment of the present invention, for the case of acquiring the PLMN list signed by the local device and the roaming destination according to the locally stored PLMN list, the locally stored PLMN list may also be updated periodically, for example, the server periodically issues the latest PLMN list signed by the mobile terminal and all countries and regions around the world to the mobile terminal, and the list includes all signed identifiers, so that the mobile terminal stores all PLMN identifiers signed by the local device and all countries and regions around the world, and the mobile terminal is convenient to acquire the PLMN list signed by the local device and the roaming destination.
In the embodiment of the present invention, the PLMN list subscribed by the mobile terminal and the roaming destination is replaced with the currently used PPLMN list, which may be deleting the PPLMN list stored in the operating memory of the mobile terminal, and writing the PLMN list subscribed by the mobile terminal and the roaming destination into the operating memory of the mobile terminal. The operating memory may be an operating memory of a communication processor of the mobile terminal.
It can be understood that the PPLMN list currently used by the mobile terminal should be stored in the operating memory, so that the mobile terminal can search for the PLMN using the currently used PPLMN list, based on which, in this embodiment, the PPLMN list stored in the operating memory of the mobile terminal is deleted, and the PLMN list subscribed by the mobile terminal and the roaming destination is written into the operating memory of the mobile terminal, so that the PLMN list subscribed by the mobile terminal and the roaming destination is replaced by the currently used PPLMN list, so that the mobile terminal can search for the network at the roaming destination using the PLMN list subscribed by the roaming destination.
For example, the information of the currently used PPLMN list in the operating memory of the mobile terminal includes PPLMNs of multiple countries such as china, the united states, japan, france, and the like, and according to the method in this embodiment, the mobile terminal determines that the roaming destination planned by the user is the hong kong region of china, deletes the PPLMN list stored in the operating memory of the mobile terminal, and writes the PLMN list signed with the hong kong region of china into the operating memory of the mobile terminal, so that the PLMN list signed with the hong kong region of china is replaced with the currently used PPLMN list, which is convenient for the mobile terminal to search for a network when roaming in the hong kong region of china.
In the embodiment of the invention, the PLMN list signed with the roaming destination is replaced by the currently used PPLMN list, so that the mobile terminal can adjust the currently used PPLMN list by using less read-write actions, and the mobile terminal can conveniently and quickly adjust the currently used PPLMN list.
The data size of the PLMN list subscribed by the mobile terminal and the roaming destination only includes the PLMN identifier subscribed to one geographic area, and therefore, the data size limit of the PPLMN list by the mobile terminal is not exceeded in general, and therefore, the PPLMN list adjusted by the method in this embodiment still satisfies the data size limit of the PPLMN list by the mobile terminal.
In order to prevent the PLMN list subscribed to the roaming destination from being lost in power down, in this embodiment, the PLMN list subscribed to the roaming destination is written into the operating memory of the mobile terminal, and meanwhile, the PLMN list subscribed to the roaming destination is also written into a file system of the mobile terminal, which may be a file system of a communication processor of the mobile terminal, so that the PLMN list subscribed to the roaming destination is not lost in power down.
In another embodiment, in step 204, the adjusting, by the mobile terminal, the PPLMN list of the mobile terminal according to the roaming destination may further include: acquiring a PLMN list signed by the mobile terminal and the roaming destination, wherein the PLMN list comprises identifiers of all PLMNs signed by the mobile terminal and the roaming destination; and determining the currently missing PLMN identifications signed with the roaming destination of the mobile terminal according to the PLMN list, and writing the currently missing PLMN identifications signed with the roaming destination into the currently used PPLMN list, so that the mobile terminal stores all the PLMN identifications signed with the roaming destination.
The method for acquiring the PLMN list signed by the mobile terminal and the roaming destination may be as described above, after the mobile terminal acquires the PLMN list signed by the roaming destination, that is, after acquiring all the identifiers of the PLMNs signed by the roaming destination, the mobile terminal compares the PLMN identifiers in the acquired PLMN list with the currently stored PLMN identifiers signed by the roaming destination one by one, thereby determining the currently missing PLMN identifiers signed by the roaming destination, and the mobile terminal writes the currently missing PLMN identifiers signed by the roaming destination in the currently used PPLMN list, thereby storing all the PLMN identifiers signed by the roaming destination.
By the method, the PPLMN list of the mobile terminal can be accurately adjusted, and the mobile terminal is ensured to store all PLMN identifications signed with the roaming destination.
Fig. 3 is a flowchart illustrating a PPLMN list adjustment method according to another embodiment of the present invention, as shown in fig. 3, the method further includes step 206, after step 204 based on fig. 2, after reaching the roaming destination, searching for a PLMN of the roaming destination according to the adjusted PPLMN list.
Specifically, after the mobile terminal detects that the mobile terminal reaches the roaming destination, the mobile terminal can search the PLMN of the roaming destination according to the adjusted PPLMN list, and since the adjusted PPLMN list contains the identifiers of all PLMNs subscribed with the roaming destination, the mobile terminal can quickly search and register the network of the roaming destination, thereby improving the network searching and registering efficiency of the mobile terminal.
In view of the fact that a user may purchase a roaming package through a virtual SIM card application in a mobile terminal, so as to utilize the mobile terminal to talk or surf the internet in a roaming area, in this embodiment, a PPLMN list adjustment method is further provided, and fig. 4 is a flowchart of the PPLMN list adjustment method according to another embodiment of the present invention, as shown in fig. 4, the method includes the following steps:
The roaming package may be a roaming traffic packet and/or a roaming call packet.
In the PLMN list contracted with global PLMN of all countries and regions, the identities of all PLMNs contracted with global PLMN of all countries and regions are recorded.
The currently used PPLMN list is replaced with the PLMN list subscribed to the roaming site, step 410.
In step 412, after detecting that the local device arrives at the roaming place, searching for the PLMN by using the currently used PPLMN list.
Through the method in fig. 4, after detecting that the user purchases the roaming package, the mobile terminal may adjust the currently used PPLMN list according to the roaming destination in the roaming package, so that the mobile terminal may quickly search for a network and register after arriving at the roaming destination.
In summary, with the PPLMN list adjustment method in this embodiment, the currently used PPLMN list can be adjusted to the PLMN list corresponding to the roaming destination planned by the user under the condition that the storage space occupied by the PPLMN list by the mobile terminal is limited, so that the time consumed by the mobile terminal in network search at the roaming destination is reduced, and the network search efficiency and the network access efficiency are improved.
