摘要
富通信套件(RCS)是GSMA制定的具有互操作性的IMS通信服务标准,状态发布与订阅授权是RCS业务的重要组成部分,根据RCS业务中状态发布以及订阅授权的要求,参考IETF、OMA、GSMA标准,提出了RCS的隐私策略的解决方案,包括隐私策略的框架图以及SIP信令流程。并在该解决方案的基础上详细讨论了实现隐私策略的关键技术:呈现(presence)信息的处理、订阅授权流程以及授权规则文档的处理。经实验测试,该解决方案已经实现了RCS隐私策略中在线状态发布、订阅授权以及权限设置功能。
RCS is an interoperable standard for IMS communication services, which was developed by GSMA.Presence and authorization are important parts of the RCS program.According to the requirement of presence and authorization, as well as referring to IETF, OMA, GSMA standards, this paper proposes an implementation project for RCS privacy, which includes a framework and a SIP signaling sequences.This paper mainly discusses the key technologies used in the implementation process of RCS privacy, which includes the processing strategy of presence, signaling sequences of subscription, and the processing strategy of authorization documents.The experimental result shows that this project has implemented functions, which are required by RCS privacy.
