Embodiment 1

[0045] refer to figure 1 , showing a flow chart of a cell access method in an embodiment of the present invention, specifically including:

[0046] Step 101, if it is detected that the mobile terminal is in a high-speed rail scenario, then search whether there is at least one accessible cell.

[0047] 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 the mobile terminal to detect the moving speed can be realized by the prior art, and the present invention will not repeat it here.

[0048] In the embodiment of the present invention, if the mobile terminal detects that the mobile terminal is currently in a high-speed rail scene, it searches whether there is one or more accessible cells in the vicinity. In the embodiment of the present invention, when the mobile terminal is in a high-speed ...

Embodiment 2

[0064] refer to figure 2 , showing a flow chart of a cell access method in an embodiment of the present invention, specifically including:

[0065] Step 201, obtaining a list of preset high-speed rail private networks.

[0066] 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 side, which can be obtained in the following ways:

[0067] Obtain the preset high-speed rail private network list from the server according to the received user instruction; or, periodically obtain the preset high-speed rail private network list from the server according to a predetermined cycle.

[0068] In an embodiment of the present invention, cell location information, cell frequency point information, and cell identification information are recorded in the preset high-speed rail private network list. Among them, all or part of the information recorded in the preset high-speed rail private...

Embodiment 3

[0097] refer to image 3 , shows a block diagram of a mobile terminal 300 in an embodiment of the present invention. Specifically include:

[0098]The search module 301 is configured to search whether there is at least one accessible cell if it is detected that the mobile terminal is in a high-speed rail scenario.

[0099] 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 the mobile terminal to detect the moving speed can be realized by the prior art, and the present invention will not repeat it here.

[0100] In the embodiment of the present invention, if the mobile terminal detects that the mobile terminal is currently in a high-speed rail scenario, the search module 301 searches whether there is one or more accessible cells in the vicinity. In the embodiment of the present invention,...

Abstract

An embodiment of the present invention provides a cell access method and a mobile terminal. The method includes: if it is detected that the mobile terminal is in a high-speed rail scenario, then searching whether there is at least one accessible cell; if so, obtaining at least one accessible cell The cell feature information of each accessible cell in the cell; match the cell feature information of each accessible cell with the cell feature information in the preset high-speed rail private network list, wherein the mobile terminal stores the preset high-speed rail Private network list; according to the matching result, select the target cell from at least one accessible cell; access the target cell; obtain the cell type information of the target cell; determine whether to update the cell in the preset high-speed rail private network list according to the cell type information characteristic information. This effectively improves the probability of the mobile terminal staying in the private network of the high-speed rail in the high-speed rail scenario, improves the communication quality of the mobile terminal in the high-speed rail scenario, avoids the phenomenon of disconnection, and improves the user experience.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a cell access method and a mobile terminal. Background technique [0002] With the development of the urban economy, the railway transportation system undertakes more and more passenger transport tasks. According to the development trend of high-speed rail in the future, the high-speed rail coverage plan needs to meet the high-speed driving requirements of 350km / h and above, and the fastest 450km / h. High-speed mobile communication faces new challenges: [0003] Large penetration loss: new trains on high-speed railways adopt a fully enclosed carriage structure, the carriage body is made of metal materials such as stainless steel or aluminum alloy, and the window glass is made of thicker glass material, which leads to the penetration loss of wireless signals outside the high-speed train It is relatively large, which brings great difficulties to the wireless...
