一种Diameter消息自动编解码的实现方法

摘要

During the process of the Diameter message encoding and decoding, in order to solve the problem of high symbol error rate, complicated process and post-maintenance difficult, provides an automatic codec of Diameter message, which defines the Diameter massage according to the logical relationships between all information elements, and automati-cally generates the interfaces of encoding and decoding that can be called directly by the telecommunication systems. This method can better meet the requirements of Diameter message codec in practical applications, which makes the codec process far easier, reduces the error rate, and improves the codec process efficiency and maintainability.%目前通信系统中Diameter消息的编解码基本通过手工编写代码，当消息发生变化时需要重新手工修改编解码代码。针对此过程中编解码效率低、误码率高、代码难维护的问题，将Diameter消息的所有信息元素按照其属性及之间的逻辑关系使用一种数据结构进行消息的结构化定义，并依据该结构化定义自动生成编解码接口，从而使编解码过程简捷，提高了编解码效率，降低了误码率；而且当Diameter消息改变时，只需修改消息定义表格，再重新生成消息的数据结构和编解码接口，从而提高了编解码过程的可维护性。该方法更好地满足了Diameter消息编解码在实际应用的要求。
