基于模型驱动的CMCE协议栈的设计与实现

Design and Implementation of CMCE Protocol Stack Based on Model Driven

在数字集群通信网络广泛应用的背景下,采用基于模型驱动的开发模式,对数字集群电路模式控制实体进行设计、开发和测试。首先简要地分析数字集群空中接口协议栈的总体结构,概述CMCE(电路模式控制实体)的结构框架,然后详细说明呼叫控制部分的设计,重点介绍呼叫控制部分的业务流程、原语和PDU(协议数据单元)的设计以及状态机的设计。最后采用Rhapsody作为开发软件对协议栈进行实现和一致性测试,各项测试结果符合协议标准。

It＇s in context that the digital trunking communications network is widely used,the development model based on model-driven is used to design,develop and test on the digital trunking circuit mode control entity.First,an overall structure of digital trunked air interface protocol stack is briefly analyzed and a framework of CMCE is summarized.Then,the design of call control is described in detail,and the designs of call control business processes,primitives,PDU and status machine are emphasized.Finally,Rhapsody is used as the development software to implement the protocol stack and its conformance testing,the test results comply with protocol standards.
