Switching method for mobile communication system

Abstract

This invention discloses a switching method in mobile communication system, which is suitable for a synchronous system, including: A, calculating a timing advance of a target base station when the terminal receives the switching command information from a source base station; B, the terminal sends a channel quality indication and resource request to the target base station and the target base station returns a resource authorization to terminal; C, the terminal sends the switching confirmation information to the target base station, then the switching is finished. The method adopting this invention is capable of reducing the time from the source base station to the target base station in the switching process so as to enable the terminal to quickly finish the synchronization with the target base station and without reducing the success rates of the other random access process.

[0013] To sum up, in a network that schedules synchronous uplink and downlink wireless resources according to the shared channel method, in the handover process of the prior art, the following two situations may introduce time delay: 1. During the random access process between the terminal and the target base station , after the terminal receives the handover command, it may not be a
