TD-LTE多模终端系统间小区重选研究与实现

Research and Implementation of Inter-System Cell Reselection between TD-LTE Multimode Terminal Systems

LTE全球已经进入全球部署阶段,今后很长的一段时间内,网络运营以及相应终端产品演进的方向是:让用户能够体验TD-LTE高速业务的同时,合理利用现有的GSM/CDMA网络。网络的发展必然要以终端的适应为前提,因此研究TD-LTE多模终端使其满足多网融合的需求势在必行。该文正是产生于这样的背景下,从协议栈软件开发的角度系统地阐述了TD-LTE多模终端系统间互操作重点过程小区重选过程,从协议分析到实现,再到测试验证的完整开发过程。

LTE has entered the stage of global deployment.For a long time in the future,the direction of network operation and corresponding terminal product evolution is to enable users to experience TD-LTE high-speed business and make rational use of existing GSM/CDMA network.The development of network must be based on the adaptation of terminals,so it is imperative to study TD-LTE multi-mode terminals to meet the needs of multi-network convergence.This paper is based on this background.From the perspective of protocol stack software development,it systematically describes the key process of interoperability between TD-LTE multimode terminal systems:cell re-selection process,from protocol analysis to implementation,and then to the complete development process of test and verification.
