摘要
针对TD57 版本3(TAP3)基于ASN.1 的二进制数据结构,定义的电讯业务中漫游数据文件交换的格式标准,不能直接被编码和 解码程序使用。通过分析 TD57 的词法关键字及其关系,给出了将TD57 转换为编码和解码程序使用的向导数据结构算法, 通过电讯业 务实践验证新算法使编码和解码程序与标准TD57 互相独立;基于此开发了 TAP3 的编码和解码程序,由于编码和解码程序直接以此结构 为向导,它更易于应用和维护。
TD57 Version 3 (TAP3) defines the standard format of roaming file exchange applied in telecommunication business. It possesses of an ASN.l based binary data structure and hence cannot be used directly by both the encoder and the decoder programs. This article lays emphasis on the analysis of the TD57 syntax by using its keywords and their relationship. A new algorithm for guiding data structure syntax translation is given, and the encoding and decoding programs are independent of the standard TD57 by using it in telecommunication business. It can be used by both the encoding and the decoding processes. Based on this work, the ASN.1(TAP3) application of encoding and decoding has been developed. Because the encoding and decoding program is directly uses the data structures, they are easy-maintained.
