Research of Rapid Baton Handover Based on GIS

摘要: 针对目前TD-SCDMA系统中接力切换技术在高速环境下存在着掉话率高，切换效率较低的情况，本论文对接力切换算法做了改进，提出了基于基站的地理位置信息的快速接力切换算法，这种算法可以解决接力切换在高速环境下移动终端来不及切换而发生掉话的情况，提高了系统的性能。

Abstract: For the current baton handover technology of TD-SCDMA system, there are high rate of dropped calls and low switching efficiency in the high-speed environment. The thesis has made improve-ments for the relay switch algorithm. It advanced the rapid relay switching algorithm based on the location of base station, which could solve the situation of the mobile terminal dropped calls in the baton handover system; when the mobile terminal occurs to relay switching in the high-speed en-vironment, this algorithm improves the performance of the system.
