| 摘 要： | 越区切换是蜂窝移动通信系统中的关键技术之一,第三代移动通信系统TD-SCDMA中采用了一种新型的越区切换技术—接力切换。文章在完整阐述其基本概念、切换过程和切换算法的基础上,对比硬切换方式,建立切换仿真模型并进行了仿真,得到上行传输功率和FTP业务上传响应时间的性能参数曲线。仿真结果证明,接力切换在降低上行干扰、缩短切换时延、降低掉话率方面性能更加优良。

| Abstract: | Handover is one of the critical techniques of cellular mobile communication system. A new kind of handover technique baton handover is adapted in TD-SCDMA system. After giving its general concepts,handover procedure and handover algorithm,a handover simulation model was formed. Compared with hard handover in uplink transmission power and FTP upload response time,the results confirmed that baton handover performed better in reducing uplink interference and shortening handover delay. |
