Abstract

The 3 GPP IP multimedia subsystem (IMS) is currently expected to provide the basic architecture framework for the next generation network which will bridge the traditional divide between circuit-switched and packet-switched networks and consolidate both sides into one single network for all services. Therefore, the imminent commercial roll-out of IMS will have immense impact on the whole way future mobile business applications are designed, developed and deployed. This paper presents a survey about the application-oriented research project CAMPARI (configuration, architecture, migration, performance analysis and requirements of 3G IMS) which aims at inves-tigating a "minimal-optimal" IMS configuration with respect to architecture and quality-of-service aspects. After a brief survey of the IMS core components, we introduce our OpenSER-based IMS prototype implementation and present the "IMS in a bottle " approach. Based on our practical experiences with this testbed system, we finally discuss important current and future challenges including migration, interworking, charging, identity management, security, and regulatory aspects.

“瓶中的IMS”:基于openser的3GPP IP多媒体子系统原型实现的初步经验

3gpp IP多媒体子系统(IMS)目前有望为下一代网络提供基本架构框架，该网络将弥合电路交换网络和分组交换网络之间的传统鸿沟，并将两者合并为一个单一的网络，用于所有业务。因此，IMS即将出现的商业部署将对未来移动业务应用程序的设计、开发和部署产生巨大的影响。本文介绍了面向应用的研究项目CAMPARI (3G IMS的配置、体系结构、迁移、性能分析和需求)的调查，该项目旨在研究体系结构和服务质量方面的“最小-最优”IMS配置。在简要介绍了IMS核心组件之后，我们介绍了基于openser的IMS原型实现，并提出了“瓶中IMS”方法。根据我们对该测试平台系统的实践经验，我们最后讨论了当前和未来的重要挑战，包括迁移、互连、收费、身份管理、安全性和监管方面。
