摘要
基于ASN.1及其UPER编码规则的理论,提出了LTE-Uu接口协议栈中ASN.1编解码模块的设计与应用方案。设计过程首先包含完整编译码所需信息的数据结构,并通过调用独立的编解码函数库,从数据结构中提取相应的参数完成解析。通过检验ASN.1编解码模块在协议一致性测试中的应用,该模块能够达到3GPP协议实际测试的要求。
A practical project on the design of the ASN. 1 encoder and decoder in the LTE-Uu interface protocol stack is put forward and realized in this paper on the theory of the ASN.1 and its UPER coding rule. The design contains the complete coding and decoding information data structure, and by calling a separate codec library, the corresponding parameters is extracted from data structure to complete the analysis. By examining the ASN.1 encoding and decoding modules in protocol conformance testing application, it is demonstrated that the function of ASN.1 encoder and decoder modules meet the 3GPP protocol actual testing requirements.
