摘要： 开发长期演进(LTE)协议必须实现针对无线资源控制(RRC)消息的ASN.1编解码模块，但传统的ASN.1编解码方案函数调用频繁，编码效率较低。为此，分析LTE协议栈的软件需求，提出一种ASN.1编解码模块设计与实现方案。该方案采用模块化设计，从而简化函数调用、提高编码效率。在TD-LTE无线综合测试仪的协议栈软件中实现并进行测试，结果表明，该方案可实现对RRC消息的编解码。

Abstract: It is necessary to realize the Abstract Syntax Notation One(ASN.1) for Radio Resource Control(RRC) in development of Long Term Evolution(LTE) protocol, but the efficiency of traditional method is low. Aiming at this problem, this paper proposes a novel design method of ASN.1 encode/decode module to meet the requirement of LTE protocol stack. The method adopts modular design, simplifies function call and improves code efficiency. It realizes and tests ASN.1 encode/decode module in TD-LTE wireless comprehensive measurement instrument. Testing the functions of this module, it proves the effect of module to encode and decode in RRC information of LTE protocol stack. It is practically useful and owns promotional value.
