As an optional implementation manner, before performing step 101 or during the process of performing the embodiment of the present invention, the mobile terminal may further perform the following steps:
recording the historical data of successful network searching of the mobile terminal, wherein the historical data comprises the frequency points, the cells, the signals of the cells and the position information of the mobile terminal; according to the collected position information of the mobile terminal, carrying out segmentation processing on the signal coverage position to obtain a plurality of signal coverage ranges; and according to the historical data, making a preset corresponding relation between the search strategy and the signal coverage range.
In the above optional embodiment, in the use process of the mobile terminal, the frequency point, the cell corresponding to the frequency point, the signal and the signal strength of the cell, the location information of the mobile terminal, and the like that are successfully searched before the mobile terminal accesses the network again each time are recorded, and the recorded information is used as the primary historical data of the mobile terminal that successfully searches the network, and a fast and effective network search strategy is made by combining a large amount of historical data.
Specifically, a geographical location area formed by the location information is reasonably segmented according to the recorded location information of the mobile terminal, or a signal coverage location formed based on the location information is segmented to obtain a plurality of signal coverage areas, for example, the recorded location information of the mobile terminal indicates xx school, xx market, etc., and then the location information is combined with xx school, xx market, etc., so that the location information is divided into two signal coverage areas, namely xx school and xx market.
Further optionally, the mobile terminal, according to the historical data, formulating the preset corresponding relationship between the search strategy and the signal coverage area may specifically include: selecting weak signal intensity cells with signal intensity smaller than a signal intensity threshold value and cells except the weak signal intensity cells in the signal coverage range as target cells in the signal coverage range according to the signal intensity of the corresponding cells in each signal coverage range, carrying out network searching priority ordering on the target cells in the signal coverage range to obtain preset priority of network searching of the target cells in the signal coverage range, obtaining a searching strategy of the signal coverage range according to the preset priority, and establishing a preset corresponding relation between the signal coverage range and the corresponding searching strategy.

Finally, a search strategy corresponding to the signal coverage is generated according to the preset priority of the target cell network search and the filtered weak signal strength cell, and it can be understood that the search strategy indicates to search the network according to the preset priority of the target cell and also indicates to filter the weak signal strength cell (specifically, the cell ID of the weak signal strength cell) except the target cell in the signal coverage.
Further optionally, each cell may correspond to one or more frequency points, when a certain cell is searched, sequential searching may be specifically performed according to the frequency point sequence under the cell, and after network searching fails for all the frequency points of the cell, a cell corresponding to the next priority is searched. Correspondingly, in the embodiment of the present invention, the search strategy may be specifically configured to indicate that network search is performed according to a preset priority order of the target cells and according to a preset frequency point priority for each target cell.

Example two
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a network searching method of a mobile terminal according to another embodiment of the present invention; as shown in fig. 2, the network searching method of the mobile terminal may include:
201. the mobile terminal acquires current position information.

Through the implementation mode, a user can set a certain character string for unlocking the touch screen, and the unlocking is convenient and quick. It should be noted that, the unlocking characters of the target unlocking key are sequentially acquired to form a character string representation: and acquiring unlocking characters of the target unlocking key according to the operation sequence of the target unlocking key to form a character string.

205. The mobile terminal searches the network by the frequency point which is recorded and corresponding to the current position information and is successful in network searching; if the network searching is successful, the process is ended, and if the network searching is failed, the process goes to step 206.
206. The mobile terminal searches for a network by using a Registered Public Land Mobile Network (RPLMN); if the network searching is successful, the process is ended, and if the network searching is failed, the process goes to step 207.
It should be noted that, in the embodiment of the present invention, the RPLMN may be used to perform network search first, and if the RPLMN fails to search for a network, the RPLMN may then use the frequency point corresponding to the current location information where network search is successful to perform network search, so that the execution sequence of steps 205 and 206 is not limited.
207. The mobile terminal carries out network search by adopting a conventional network searching mode; if the network searching is successful, the process is ended, and if the network searching is failed, the process goes to step 208.
It should be noted that the normal search mode refers to sequentially traversing each network mode in the SIM and frequency points in each network mode, which is not described herein again.
208. The mobile terminal judges whether the failure times of network searching failure in the conventional network searching mode are not less than preset times or not; if the number of times is less than the preset number, turning to step 207; if not less than (equal to or greater than) the preset number of times, the process goes to step 209.
209. The mobile terminal prompts the network searching failure and ends the process.
It can be seen that, by implementing the above embodiment, a search strategy for network search is set in advance for each signal coverage, and the search can be performed according to the priority of the cell based on the search strategy, so as to improve the search efficiency and reduce the number of interactions with the access network, and the search strategy is not for a part of mobile terminals, but is applicable to all mobile terminals and various scenes requiring network re-access, so as to improve the market share of the mobile terminals; after the network search fails by adopting the established search strategy, the network search can be further carried out by adopting the recorded frequency points with successful search, if the network search fails, the RPLMN can be continuously adopted for network search, and if the network search still fails, the network search is finally carried out by adopting a conventional network search mode.
