呈现业务在IMS终端的研究与应用

Research and Application of Presentation Service in IMS Terminal

随着智能终端广泛应用,传统语音业务对于用户来说已经不是最为关注的业务,人们希望在移动互联网中能随时感知网络中用户的通信能力、位置、状态等信息,用户可以根据对方的状态信息选择合适的通信方式,而目前市场上很多支持呈现业务的软件都采用了私有协议,相互之间不能兼容,很难作为规范来学习;在参考IETF工作组提出的SIMPLE框架关于状态订阅和发布机制后,并实现一种基于资源列表的呈现业务模型,经过测试,性能良好,能完成状态的发布和状态订阅功能。

With the widespread application of smart terminals,traditional voice services are not the most concerned services for users.People want to be able to sense the communication ability,location,status and other information of users in the mobile Internet at any time,and users can choose the appropriate communication mode according to the status information of each other.Nowadays,many types of software that support the presentation business in the market adopt private protocols,which are incompatible with each other and difficult to learn as a specification.After referring to the SIMPLE framework proposed by the IETF working group on the state subscription and publishing mechanism,a resource list-based presentation business model is implemented.Experimental test indicates that the model performs well and can complete the status release and status subscription functions.
