摘要/Abstract

摘要： 为解决数字集群通信系统中图像、视频等大数据业务的传输问题，深入分析数字集群空中接口协议栈的结构，重点研究分组数据业务提供者子网相关汇聚协议的结构和原理。基于模型设计方法设计该协议的相关功能模块，并进行编码实现。开发中使用IBM Rational Rhapsody这一基于UML建模的开发工具，使整个开发过程简洁而清晰。最后，通过对协议进行一致性测试，证明协议参数及流程符合数字集群通信系统协议标准。

关键词: 数字集群, 模型设计, 协议栈, 分组数据, 子网相关汇聚协议

Abstract: To solve the problem that transfer multi-data like images, videos in digital trunked communication system, the air interface protocol stack of digital trunked is analyzed deeply, and the sub-network dependent convergence protocol (SNDCP), which is the provider of packet data service, is researched. Then, the dependent function model of the protocol is designed and coded based on model design. In developing, IBM Rational Rhapsody which is a develop tool based on UML is used to make the develop program easy and clear. At last, parameters and sequence of the protocol are proved to be compliance with the protocol standard of digital trunked communication system by making conformance tests to the protocol.

Key words: digital trunked, model design, protocol stack, packet data, sub-network dependent convergence protocol
