一种基于IMS域的移动增值新业务:PoC

文章介绍了一种基于IMS域的移动增值新业务:无线一键通(PoC)业务,讨论了其实现方案,并对典型PoC业务的SIP信令交互流程进行了描述.在对PoC技术的优缺点进行分析的基础之上,文章探讨了未来PoC业务的用户定位问题,得出结论:企业级用户群、社团用户群以及主要由白领和青少年组成的个人用户群将是PoC业务的市场主体.文章认为PoC系统完全可以充当彩信、即时消息、状态呈现、图片收发等众多新业务的工具,将像短信业务那样,最终形成终端厂商、设备厂商、服务提供商、运营商合作共赢的PoC产业价值链.

A New Wireless Value-added Service Based on IMS: PoC

This article introduces the PoC (Push-to-talk over Cellular) service, a new value-added mobile service based on the 3GPP IP Multimedia Subsystem (IMS). Its implementation scheme is discussed and its SIP (Session Initiation Protocol) signal exchange flow is described. Based on the analysis on the advantages and disadvantages of PoC services, target user groups are predicted. It is concluded that the main body will be the enterprise user group, corporation user group and white-collar and teenager user group. The PoC system, undoubtedly, can be used as a platform for new services such as coloring message, instant message, presence-personal alert, and picture receiving and sending, and just like the short message service, the PoC service will help vendors, content providers and operators setup a win-for-all value chain.
