Cell switching method, information transmitting method, and related equipment

Abstract

The invention discloses a cell switching method, an information transmitting method, and related equipment. Cell switching efficiency is improved in a specific scene of high speed train operation, and therefore communication performance of terminal equipment is improved. The cell switching method comprises steps that the terminal equipment is used to acquire a cell switching list transmitted by a base station corresponding to a current service cell; the terminal equipment is used to determine whether a current moving state is in a high speed moving state; when the current moving state is a high speed moving state, the cell comprising a first identification selected from the cell switching list is identified as a first target cell, and the first identification is used to identify the first target cell as the high speed service cell; the high speed service cell is the cell in a high speed rail preset distance range; the terminal equipment is used to identify a second target cell from the first target cell according to signal intensity; and the terminal equipment is switched from the current service cell to the second target cell.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell switching method, an information sending method and related equipment. Background technique [0002] High-speed rail is a very fast-moving railway. In order to adapt to the operating environment of high-speed rail and ensure the communication quality of high-speed rail users, the signal strength in the high-speed rail communication network is relatively high, usually stronger than that of public communication networks. [0003] The high-speed rail travels at a high speed, which often leads to unstable mobile phone signals, calls are easy to drop, and GPRS data is also very slow. For example, if a mobile phone user in a high-speed train on a high-speed train initiates a call access request when at the edge of a cell, because the high-speed rail is too fast, the mobile phone user has already moved to another cell before completing the access process. , the mobile phone has...

Problems solved by technology

[0003] The speed of the high-speed rail is fast, which often leads to unstable mobile phone signals, calls are easy to drop, and GPRS data is also very slow.

For example, if a mobile phone user in a high-speed train on a high-speed train initiates a call access request when at the edge of a cell, because the high-speed rail is too fast, the mobile phone user has already moved to another cell before completing the access process. , the mobile phone has not completed the cell measurement and it is too late to initiate a cell handover, resulting in the call access failure
