异构网络的资源控制体系

Resource Control Architecture in Heterogeneous Networks

TISPAN从固定接入角度出发,提出了资源接纳控制子系统来解决NGN承载网的QoS问题;3GPP则从移动接入角度出发,在最新的3GPPR7草案中,把R6版中的策略控制功能和基于流的计费功能合并,提出了策略控制和计费。随着固定移动的融合,资源接纳控制体系在架构和接口上的不一致性对NGN相关设备制造和网络实施将产生重大的影响。目前,3GPP和TISPAN都开展了Gq'/Rx参考点融合的研究课题。下一代移动网络论坛提出了和谐PCC的概念和需求,即异构网络的协同资源控制体系架构,代表了异构网络的资源控制技术和体系的演进方向。

TISPAN from a fixed access perspective proposes Resource Admission Control Subsystem （RACS） as a solution to Quality of Service （QoS） for NGN bearing network. In contrast, 3GPP has an approach to this via mobile access. In the latest 3GPP R7 draft, integration of Policy Control Function （PCF） with traffic based billing function of the R6 version brought forward policy control and billing. With the development of fixed mobile convergence, the inconsistence between architecture and interface of resource admission control Will have a huge impact on manufacture and network implementation of NGN related equipment. To solve this problem, both 3GPP and TISPAN have been working on convergence of Gq＇/RX reference points. Harmonized Policy Control and Charging （PCC） proposed by Next Generation Mobile Network （NGMN） forum, i.e. cooperative resource control architecture for heterogeneous networks represents an evolutional sign post for resource control technology for heterogeneous networks architecture.
