摘要

介绍了TD-LTE（时分-长期演进）系统所规范的小区切换过程

并重点研究了切换执行过程中的随机接入过程。结合TD-LTE协议一致性测试的特点和实际开发经验

通过执行无线资源管理异频切换测试例

对测试仿真图进行了分析

最后从仿真数据可以看到终端按源小区的前导配置向目标小区发起随机接入

有效验证了切换中的随机接入过程的协议一致性。

Abstract

This paper introduces the cell handover procedure specified in the TD-LTE（TD-SCDMA Long Term Evolution）system

and focuses on the random access procedure in handover execution.In line with the features of the TD-LTE protocol conformance test and the practical development experience

this paper analyzes the handover test simulation diagrams by performing the Radio Resource Management（RRM）different frequency handover test cases and can see from the simulation data the random access initiated by the terminal to the target cell according to the preamble configuration of the source cell

effectively verifying the protocol conformance of the random access procedure in the handover.
