Example two
Referring to fig. 2, a flowchart of a cell access method in the embodiment of the present invention is shown, which specifically includes:
step 201, acquiring a preset high-speed rail private network list.
Specifically, in the embodiment of the present invention, the mobile terminal needs to obtain the preset high-speed rail private network list from the server, and the preset high-speed rail private network list can be obtained through the following manners:
acquiring a preset high-speed rail private network list from a server side according to a received user instruction; or, according to a preset period, a preset high-speed rail private network list is periodically acquired from the server side.
In the embodiment of the invention, the preset high-speed rail private network list records cell position information, cell frequency point information and cell identification information. All or part of information recorded in the preset high-speed rail private network list is preset by an operator according to the network distribution condition, part of information can be updated by the mobile terminal in the actual connection process, and the specific updating process refers to the following embodiments.
Step 202, if it is detected that the mobile terminal is in a high-speed rail scene, searching whether at least one accessible cell exists.
Specifically, in the embodiment of the present invention, the mobile terminal detects the current moving speed of the mobile terminal in real time, so as to determine whether the mobile terminal is in a high-speed rail scene. The method for detecting the moving speed of the mobile terminal can be realized by the prior art, and the invention is not repeated herein.
In the embodiment of the invention, if the mobile terminal detects that the mobile terminal is in a high-speed rail scene at present, whether one or more accessible cells exist nearby is searched. In the embodiment of the invention, the mobile terminal is divided into an idle state and a connected state when the mobile terminal is in a high-speed rail scene.
Step 203, cell characteristic information of each accessible cell in the at least one accessible cell is obtained.
Specifically, in the embodiment of the present invention, if the mobile terminal detects that one or more accessible cells currently exist in a high-speed railway scene, the cell feature information of each accessible cell is acquired. In the embodiment of the present invention, the cell characteristic information includes cell location information, cell frequency point information, and cell identification information.
And 204, matching the cell characteristic information of each accessible cell with the cell characteristic information in a preset high-speed rail private network list.
Specifically, in the embodiment of the present invention, step 204 specifically includes:
substep 2041, obtaining the current location information of the mobile terminal.
Specifically, in the embodiment of the present invention, the mobile terminal obtains the current location information of the mobile terminal, where the location information is latitude and longitude information.
Step 2042, determine the cell location matching range according to the current location information.
Specifically, in the embodiment of the present invention, the mobile terminal determines the cell location matching range according to the current location information of the mobile terminal. For example, the following steps are carried out: if the longitude and latitude of the current position of the mobile terminal are X, Y respectively, the longitude and latitude corresponding to all coordinate points within the range with the diameter of 2km by using X, Y as the center of a circle is the cell position matching range. The specific range may be set by an operator, and the present invention is not limited thereto.
Step 2043, search for whether there is a cell falling within the cell location matching range in the preset high-speed rail private network list.
Specifically, in the embodiment of the present invention, the mobile terminal retrieves location information of all cells in the preset high-speed rail private network list, and determines whether a cell falling within a cell location matching range exists.
Step 2044, match the cell characteristic information of each access cell with the cell characteristic information corresponding to the cell falling into the cell location matching range.
If the mobile terminal retrieves one or more cell location information falling within the cell location matching range, the cell feature information of each cell acquired in step 203 is matched with the cell feature information corresponding to the retrieved one or more cell location information.
Step 205, selecting a target cell from at least one accessible cell according to the matching result.
Specifically, in the embodiment of the present invention, if there is successfully matched cell feature information, the mobile terminal selects an accessible cell corresponding to the successfully matched cell feature information as a target cell.
In a preferred embodiment of the present invention, if there are multiple successfully matched accessible cells, the cell to be accessed is selected according to the cell signal strength of each successfully matched cell. In one embodiment, if the mobile terminal is currently in an idle state, the selected cell is the cell to be accessed. In another embodiment, if the mobile terminal is currently in a connected state, that is, the mobile terminal has currently accessed any private network cell, the selected cell is a handover cell, that is, the mobile terminal may disconnect from the current private network cell and access the selected cell at the next handover.
In addition, in another alternative embodiment of the present invention, if the cell characteristic information of each accessible cell fails to match the cell characteristic information in the preset high-speed rail transit list, the mobile terminal detects the signal strength of each accessible cell. The method for detecting the signal strength of each accessible cell can be implemented by the prior art, and the detailed description of the present invention is omitted here.
The mobile terminal then selects the cell with the strongest signal strength as the target cell.
Step 206, accessing the target cell.
Step 207, cell type information of the target cell is obtained.
Specifically, in the embodiment of the present invention, after accessing the target cell, the mobile terminal may obtain the cell type information of the target cell. In an embodiment of the invention, the cell type comprises a high-speed rail private network or a public network. The mobile terminal can judge whether the target cell is a high-speed rail private network or not according to the cell type information.
And step 208, judging whether to update the cell characteristic information in the preset high-speed rail private network list or not according to the cell type information.
Specifically, in an embodiment of the present invention, if the mobile terminal selects the target cell from the accessible cells that have failed to be matched in step 205, after the mobile terminal acquires that the cell type information of the target cell is a private network, the cell characteristic information of the target cell is added to the preset high-speed rail private network list to update the preset high-speed rail private network list. If the cell type of the target cell is public network, searching nearby accessible cells again, and disconnecting the target cell after connecting to any private network cell.
In another embodiment of the present invention, there may also be cells that originally belong to the private high-speed rail network and have been recorded in the preset private high-speed rail network list, but are later configured as a public network due to modification of configuration parameters. For the cell of the type, after the mobile terminal detects the cell of the type, since the cell characteristic information of the cell is recorded in the preset high-speed rail private network list, when the mobile terminal accesses or switches the cell, the mobile terminal still considers that the cell of the type belongs to the high-speed rail private network. Therefore, at step 205, the mobile terminal may select the cell of this type as the target cell. However, after the connection, the mobile terminal acquires the cell type information of the cell, and determines that the cell is currently configured as a public network cell, the mobile terminal searches nearby cells again, and in the case of connecting to any private network cell, disconnects the connection with the cell, and updates the preset high-speed rail private network list, that is, deletes the cell feature information related to the cell in the preset high-speed rail private network list.
In summary, according to the technical solution in the embodiment of the present invention, if it is detected that the mobile terminal is in a high-speed rail scene, whether at least one accessible cell exists is searched; if so, acquiring cell feature information of each accessible cell in at least one accessible cell; matching the cell characteristic information of each accessible cell with the cell characteristic information in a preset high-speed rail private network list, wherein the preset high-speed rail private network list is stored in the mobile terminal; selecting a target cell from at least one accessible cell according to the matching result; accessing a target cell; acquiring cell type information of a target cell; and judging whether to update the cell characteristic information in the preset high-speed rail private network list or not according to the cell type information. Therefore, the probability that the mobile terminal resides in the high-speed rail private network in the high-speed rail scene is effectively improved, the communication quality of the mobile terminal in the high-speed rail scene is improved, the phenomenon of network disconnection is avoided, and the user experience is further improved.
