多模双通道终端综测仪中TD-LTE CS Fallback至TD-SCDMA协议栈的设计与实现
首发时间:2013-09-06
摘要:随着4G TD-LTE网络在中国的推广,TD-LTE/TD-SCDMA多模终端一致性测试对于终端的研发和生产具有重要意义,而多模双通道终端综测仪起着重要的作用。CS Fallback是3GPP为LTE引入初期定义的一种标准的话音业务过渡方案,本文提出一种基于单射频的硬件结构实现TD-LTE到TD-SCDMA的CS Fallback重定向方案,可以大大降低综测仪的生产成本,在提高TD-LTE/TD-SCDMA多模终端的生产效率,降低多模终端生产成本,完善TD-LTE 和TD-SCDMA终端测试设备方面具有重要的意义。

Design and Realization of Protocol Stack of CS Fallback from TD-LTE to TD-SCDMA in Multi-mode Dual Channel Terminal Conformance Test Set
Abstract:As the spread of the 4G TD-LTE network in China, TD-LTE/TD-SCDMA multi-mode Terminal Conformance Test Set plays an important role in research and production of multi-mode mobile phone.CS Fallback is defined as a standard voice service transition program for the early introduction of the LTE network by the 3GPP.This paper proposes a CS Fallback program in redirection mode based on the hardware structure of one RF module. This solution can help to reduce cost of Multi-mode Dual Channel Terminal Conformance Test Set, increase multi-mode mobile phone production efficiency and improve the terminal test equipments.
