摘要:

TD-LTE是移动通信重要的演进方向,搜网功能是终端的重要功能之一。终端在搜网的过程中如何保证监视网络寻呼、测量和读系统消息等任务的正常进行是实现的难点,本文提出的GAP搜网方法可以很好地解决这一问题。从TD-LTE终端协议栈整体架构入手,首先对搜网功能进行了概述,设计了处理搜网功能的模块和接口,然后重点阐述了GAP搜网的原理和实现。最后对典型的场景进行了流程设计,并用SDL和TTCN仿真功能测试和验证了GAP搜网方法的可行性和有效性。

Abstract:

This paper starts with the holistic frame of the TD-LTE terminal's protocol stack. Firstly, the feature of PLMN search is summarized, and the modules and interfaces are designed to deal with the feature of PLMN search. Then, it focuses on the principle and realization of GAP PLMN search. Finally, processes of typical PLMN search scenes are designed, and SDL and TTCN co-simulation software is used to test and verify the feasibility and effectiveness of GAP PLMN search.

Key words: TD-LTE, PLMN, GAP search, SDL, TTCN
