技术领域 FIELD

本发明涉及通信技术领域,尤其涉及一种策略授权方法、系统及设备。 The present invention relates to communication technologies, and in particular, to a policy authorization method, system and device. 背景技术WiMAX ( Worldwide Interoperability for Microwave Access,樣b皮才妄入的全球互操作性)网络的结构如图la所示,主要包括MS (Mobile Station,移动终端)、ASN( Access Service Network,业务4妻入网纟各)和CSN( Connectivity Service Network,连接业务网络)三部分。 BACKGROUND structure WiMAX (Worldwide Interoperability for Microwave Access, sample b of the sheath before the jump Worldwide Interoperability) network shown in FIG. La, including the MS (Mobile Station, a mobile terminal), ASN (Access Service Network, 4 service wife each network Si) and CSN (Connectivity service network, a network connection service) in three parts. 其中,ASN主要包括BS (Base Station,基站)和ASN-GW ( Access Service Network Gateway,接入业务网络网关)等; CSN主要包括PPS (Prepaid Server,预付费服务器)和AAA (Authentication Authorization Accounting,认证、授权和计费)服务器等逻辑实体。 Wherein, ASN including BS (Base Station, base station), and ASN-GW (Access Service Network Gateway, Access Service Network Gateway) or the like; the CSN mainly include PPS (Prepaid Server, prepaid server) and AAA (Authentication Authorization Accounting, authentication , authorization and accounting) server logical entity. MS与ASN 之间通过R1接口相连,MS与CSN之间通过R2接口相连,ASN与CSN之间通过R3接口相连,ASN之间通过R4接口相连,CSN之间通过R5接口相连,ASN中的BS与ASN-GW之间通过R6接口相连。 Between the MS and the ASN via an interface R1 is connected between the MS and the CSN are connected through R2 interface between the ASN and the CSN are connected via an R3 interface, an interface between ASN connected through R4, R5 are connected through an interface between the CSN, the ASN BS between the ASN-GW connected via R6 interface.

PCC (Policy Control and Charging,策略控制和计费)框架是一个适用于各种IP (Internet Protocol,网际协议)连接接入网络的策略控制和计费控制功能框架,PCC用于完成资源接纳控制,主要针对移动接入网络的特性实现一定的服务质量控制和计费策略控制,提供的主要功能包括:基于用户的定制信息实现策略控制及基于服务数据流的计费控制。 PCC (Policy Control and Charging, policy control and charging) is a framework for a variety of IP (Internet Protocol, Internet Protocol) connection to access the network policy control and charging control framework, the PCC for performing resource admission control, the main achieve certain quality of service control and charging policy control for the characteristics of mobile access networks, providing the main functions include: to achieve policy control and service data flow based charging control based on the user's customized information. PCC位于业务控制层与接入或承载层之间,向业务控制层屏蔽接入或承载层的具体技术和拓朴信息。 PCC is located between the service control layer and the bearer layer, or access specific access technology and topology information or shielding layer to the service bearer control layer. 其中,策略控制主要是指门控(Gating Control)和QoS控制(QoS Control ), 计费控制是指基于FBC ( Flow Based Charging,流的计费)。 Wherein the control strategy mainly refers gated (Gating Control) control and QoS (QoS Control), charging control means based on the FBC (Flow Based Charging, Charging flow).

为了解决业务的动态策略控制和授权,在WiMAX引入PCC架构,如图lb 所示。 In order to address the dynamic policy control and licensing business, the introduction of WiMAX PCC architecture, as shown in Figure lb.

为支持WiMAX接入网中A-PCEF的迁移,WiMAXPCC架构还引入了PDF To support the migration of the A-PCEF WiMAX access network, WiMAXPCC architecture also introduces a PDF

逻辑实体,用于向PCRF屏蔽WiMAX网络中PCC策略执行点PCEF的移动性和向A画PCEF (接入网PCEF )和C-PCEF (核心网PCEF )分发PCC Rules。 Logical entity, for shielding the WiMAX network mobility PCC policy enforcement point to the PCEF to the PCRF and PCEF Videos A (access network PCEF), and C-PCEF (core network PCEF) distributed PCC Rules. WiMAX 网络存在接入网PCEF和可选的核心网PCEF,接入网A-PCEF的功能在Anchor SFA(锚定SFA ) 、 Accounting Client/Agent(计费客户端/代理)、Anchor DPF(锚地通路实体)实现。 WiMAX PCEF network access network and the optional presence of PCEF core network, access network A-PCEF function in Anchor SFA (anchor SFA), Accounting Client / Agent (accounting client / agent), Anchor DPF (anchorage passage entity) to achieve.

在实现上述方案的过程中,发明人发现现有:f支术中存在以下缺点: 随着上层业务的发展和QoS/计费策略的精细授权,需要按终端所在的位置信息进行QoS和计费策略的授权,如根据不同的区域或路由域配置不同的QoS策略和计费费率。 During the implementation of the above-described embodiment, the inventors have found that conventional: the following disadvantages f branched surgery: With the development of the upper layer service and fine authorized QoS / accounting policy, billing and QoS required by the location information of the terminal is located authorization policy, such as the configuration of QoS policy and charging different rates depending on the area or domain. 然而,现有技术中的策略授权实体不能根据不同位置域或路由域的策略授权不同的QoS策略(如带宽,比特率)和计费策略(计费费率)等。 However, the prior art policy authorization entity not authorized according to different policies in different locations or domains QoS policy routing domain (e.g., bandwidth and bit rate) policy and charging (charging rate) and the like.
