Embodiment Construction

[0017] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0018] For the convenience of description, the embodiments of the present invention are described by taking its application in GSM as an example. However, other communication systems in wireless communication, such as Wide Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (Code Division Multiple Access, CDMA2000), Time Division Synchronous Code Division Multiple Access (Time Division- Synchronous Code Division Multiple Access, TD-SCDMA) can support the wireless communication system synchronization method and device thereof of the present invention.

[0019] Such as figure 1 Shown is a flow chart of a method for synchronizing a wireless communication system according to an embodiment of the present invention. In this embodiment, the method includes the MS receiving BTS synchronization information, the synchronization informa...

Abstract

An embodiment of the invention discloses a wireless communication system synchronization method. The method comprises steps of: a mobile terminal receiving synchronization information from a base station, the synchronization information comprising time information of the base station; extracting the time information of the base station in the synchronization information; and adjusting time of themobile terminal based on the time information of the base station. The invention simultaneously discloses a wireless communication mobile terminal, a base station and a wireless communication system.Embodiments of the invention may reduce dependence of the mobile terminal on time synchronization to a GPS satellite reception system, which may prolong start period of the GPS satellite reception system, reduce start frequency, to solve problem of excessive power consumption caused by starting the GPS satellite reception system with high frequency.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless communication system, a synchronization method and a device. Background technique [0002] In a time synchronization system, such as the Global System For Mobile Communication (GSM) system, the mobile terminal (Mobile Station, MS), the base transceiver station (Base Transceiver Station, BTS) and the base station controller (Base StationController, BSC ) need to be synchronized in time, that is, the terminal equipment and the base station equipment in the system need to keep the same time, so as to ensure the normal progress of services such as MS handover and data transmission. [0003] In the communication system, many MSs are equipped with a global positioning system (Global Position System, GPS) satellite receiving subsystem. In the working state, the MS starts the receiving subsystem regularly, receives and captures GPS satellite information and proce...
