Method and device for switching in wireless telecommunication system

Abstract

In the invention, by saving the complete information in measurement report of mobile station, when the base station system receives the incomplete measurement report of mobile station, it can uses its saved complete information in measurement report of the mobile station to make switch process so as to avoid the issue that is incapable of initiating the switch because the measurement report doesn't comprises the information of neighboring cells.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a switching method and switching device in a wireless communication system. Background technique [0002] The service area of ​​the wireless communication system is composed of continuous cells. In order to enable the mobile station to obtain continuous services from the coverage area during the mobile call, and to improve the network performance, the wireless communication system adopts handover technology. . Through the handover technology, on the one hand, the call can be kept continuous during the moving process, and on the other hand, the call drop rate and congestion rate can be reduced, so as to achieve the purpose of improving the quality of network service. [0003] GSM (Global System for Mobile communications, Global System for Mobile Communications) judges the handover based on: the measurement report regularly reported by the mobile station and the base...

Problems solved by technology

[0006] If the downlink measurement report reported by the mobile station cannot be accurately received by the base station due to poor uplink wireless environment and other reasons, so that the uplink measurement report and downlink measurement report received by the base station system are incomplete, such as the measurement report lacks neighbor cell information, etc., then The base station system does not use the measurement report as the input of the handover algorithm. In this way, the base station system does not make a handover decision. At this time, the base station system does not initiate a handover, resulting in poor call quality of the mobile station, or even call drop.

Even if the base station system uses the incomplete uplink measurement report and downlink measurement report it receives as the input of the handover algorithm, and the handover decision is passed, at this time, there is no target cell due to the lack of neighbor cell information in the measurement report. Therefore, The base station system still cannot initiate handover, so there are still phenomena such as poor call quality of the mobile station, and even call drop.
