未来移动通信业务模型及架构

B3G时代的未来移动通信系统将是一个以用户为中心，提供个性化业务体验的开放融合的信息基础设施，因此面向B3G的业务模型及业务架构的研究对未来移动通信网络建设具有基础性指导作用。基于B3G演进趋势及业务特征，业务参考模型及业务架构可分解为业务支撑范围、业务能力定义和适配特征元素维度的三维业务参考模型，从而形成B3G分层业务架构；相应地，业务提供支撑技术包括虚拟归属环境（VHE）、业务支撑环境、业务能力开放、分布式计算、智能技术、轮廓（Profile）等。VHE体系在结合功能分布、能力开放粒度、智能元素支持、体系结构等方面的研究进行扩展后，将成为B3G时代业务提供的主流架构。

Service Model and Architecture for Future Mobile Communication Systems

The future Beyond 3G(B3G) mobile communication system is envisioned as a user-centric, open and convergent information infrastructure capable of providing individualized services. Therefore, it is extremely important to develop relevant service models and architectures for B3G services. Based on the evolution trend and service features of B3G, a three-dimension service model is proposed, including dimensions of service supporting scope, service capability definition and adaptive feature element. Accordingly, a hierarchical service architecture for B3G is introduced. The enabling technologies for B3G service provision based on the architecture are discussed, such as Virtual Home Environment (VHE), service support environment, service openness, distributed computing, intelligent technology and profile. The enhanced VHE architecture, based on the research in respects of function distribution, service capability granularity, intelligent elements and architecture, is believed to be the dominant architecture in B3G.
