摘要

从时分同步的码分多址（TD-SCDMA）长期演进（TD-LTE）随机接入过程的应用场景入手

详细介绍基于竞争的随机接入过程的基本原理

并以网络端为例

设计了相应的随机接入过程媒体接入控制（MAC）子层的流程。通过说明和描述语言（SDL）以及树表结合表示法（TTCN）协仿真

生成随机接入过程的消息顺序图（MSC）

验证了信号流程设计及数据的正确性。该流程设计已应用于TD-LTE无线综合测试仪表的开发中。

Abstract

On the basis of the application scenarios of the TD-LTE random access process

this paper introduces in detail the fundamental principle of the competition-based random access process

taking network end as an example

designs an appropriate flow of the random access process Media Access Control（MAC） sub-layer.It generates its Message Sequence Chart（MSC） by SDL and TTCN co-simulation

verifying the correctness of the signal flow design and data.This design flow has been applied to the development of TD-LTE wireless integrated test instrument.
