Abstract

The present invention provides high speed mobile terminal cell switchover control method. Said method includes when terminal moves away current service base station at higher set traveling speed and approaches predicted target cell, network side judges target cell signal whether satisfying pre-switching condition, if satisfying then starting up pre-switching and establishing channel in target cell. Said invention realizes high speed mobile terminal switching through predetermining mobile terminal travel direction, pre-applying channel resource in target cell and establishing channel.

Description

technical field

[0001] The invention relates to a cell switching control method in wireless communication technology, in particular to a cell switching control method suitable for users moving at high speed. Background technique

[0002] In a global system for mobile communication (Global System for Mobile Communication, GSM), as the terminal moves, the network side often needs to perform a handover operation to change the serving cell of the terminal. Cell handover is usually initiated by the network. Generally, the signal strength and signal quality of the current serving cell and neighboring cells are obtained according to the measurement report reported by the terminal, and then the handover operation is triggered by a certain handover decision algorithm.

[0003] In transportation operations such as railways, highways, and rivers, trains, cars, and ships usually move quickly in one direction. Therefore, when wireless mobile communication is implemented, it can be handle...
