一种确定策略规则的方法、 系统及装置 技术领域
本发明涉及无线通信技术领域,特别涉及一种确定策略规则的方法、 系统及装置。 发明背景
在不同的网络中, 如何确定并下发策略规则给执行实体执行, 如策 略控制与计费规则 (PCC, Policy Control and Charging ), 或服务质量 ( QoS , Quality of Service )策略或 /和计费规则, 成为了一个亟待解决 的问题。
敖波接入全球互通 ( WiMAX , Worldwide Interoperability for
Microwave Access ) 网络工作组 ( NWG, Network Work Group )标准最 新的 QoS框架如图 1所示, 移动终端 (MS, Mobile Station )是用户的 移动终端, 用户通过 MS 与网络进行交互; 业务流管理实体(SFM , Service Flow Manager )用于建立用户业务流并为建立的业务流分配无线 资源等,该功能实体存在于 ASN中;业务流授权实体( SFA , Service Flow Authorization )用于为业务流的授权, 该功能实体存在于 ASN中; 策略 功能实体(PF , Policy Function, PF )用于为用户的业务流提供策略, 该功能实体由网络服务提供商 ( NSP, Network Service Provider )提供, 用户漫游时, 将存在拜访 PF ( V-PF , Visited PF )和家乡 PF ( H-PF , Home PF ); 应用功能实体 ( AF , Application Function )是提供应用服 务的功能实体, 用户的 MS直接通过应用层协议连接访问 AF, AF将会 通知 PF主动为用户创建业务流, 该功能实体由网络服务提供商 (NSP, Network Service Provider )提供。 网际协议多媒体子系统( IMS , IP Multiedia Subsystem ), 作为下一 代网络融合的核心, 实现了网际协议 ( IP, Internet Protocol ) 多媒体业 务的建立、 维护及管理等功能的核心网络体系结构。 可以在异构网络间 实现基于 IMS的互通。
IMS 架构的功能体主要有: 代理呼叫控制功能 ( P-CSCF ,
Proxy-CSCF ), 是用户在 IMS系统中的第一个接触点。 同一个运营商的 网络可有一个或多个 P-CSCF。其主要功能为:基于请求中 UE提供的归 属 i或名( home network domain name ),转发 UE的会话初始十办议注册( SIP REGISTER )请求给查询 CSCF ( I-CSCF ); 用户注册成功后, 可转发用 户的 SIP请求和响应消息给服务 CSCF ( S-CSCF ); 把计费信息发送给 计费收集功能(CCF, Charging Collection Function ); 执行媒体修正; 检 查 SIP会话中的媒体类型、 编码格式等是否符合要求, QoS的要求能否 被满足等; 通过 Gq 参考点与策略决策功能 (PDF, Policy Decision Function ) 交互, 传输策略配置信息, 以实现媒体授权。
PDF负责根据从 P-CSCF处获得的会话和媒体相关信息来制定策略, 它作为基于局域网服务规则( SBLP, Service Based Local Policy )控制的 一个策略决策点。 其功能为: 存储会话和媒体相关信息; 生成授权令牌 用于标识 PDF和会话; 在收到来自 IP-CAN的承载授权请求时, 根据存 储的会话和媒体相关信息来提供授权决策; 在会话变更过程修改了会话 和媒体相关信息时, 更新相应的授权决策; 启用已授权的承载的能力; 禁用已授权的承载, 但维持授权的能力; 传送一个 IMS计费标识符给网 关通用分组无线业务支持节点(GGSN ), 并且传送一个通用分组无线业 务(GPRS )计费标识符给 P-CSCF。
WiMAX标准在 Rl P介段对于与 IMS融合只是作了初步的描述: 在 Rl P介段的 WiMAX-IMS融合方案中, WiMAX网络只是作为 IMS客户 端与 IMS网络之间的一个 IP传输网络, WiMAX网络原有架构、接口不 用作改变就能支持此种方式的融合。
PCC构架是 3GPP的版本 7 ( R7 ) 中主要解决的一个问题, 其目的 是解决 QoS与计费的集成。 PCC 当前架构是根据 3GPP中 R5定义的 SBLP框架和 R6定义的基于流量计费 ( FBC, Flow Based Charging )框 架融合而成的一个方案。 如图 2所示: 其中, 将 SBLP中的 PDF和 FBC 中的 CRF融合成一个策略控制和计费规则功能实体(PCRF, Policy and Charging Rules Function ) , PDF与 CRF都是规则制定的功能实体。 将 SBLP中的 PEP和 FBC中的传输面功能( TPF, Traffic Plane Function ) 融合成策略控制和计费执行功能实体 ( PCEF , Policy and Charging Enforce Function ), 即网关( GW ), PEP与 TPF都是执行规则的功能实 体。 应用功能 ( AF, Application Function )还是继承以前原有的功能, 即提供业务信息。
另外, 将 Go和 Gx接口合并为 Gx+, 分别向 PEP/TPF提供计费规 则和策略控制规则, Gx接口支持策略控制功能, 称之为基于流的策略 控制 (FBP ), PCC面向会话层和应用层的接口 Gq和 Rx合并为 Rx+, Gq和 Rx接口在功能上很相似,把会话控制层有关 IMS会话和媒体参数 的信息传递给 PCC。 在 PCC 中增加了一个存储预定策略 (SPR , Subscription Profile Repository )功能实体, 主要是用来保存实时的用户 签约策略的实体。
PCRF包含了 SBLP中的 PDF以及 FBC中的 CRF的功能, 向 GW 提供 QoS授权信息以及计费规则。 在收到 AF的业务信息后, PCRF可 能需要检查一下是否允许 AF向 PCRF传递这些信息。 PCRF负责控制 GW收到 SDF后的行为。 与此同时, PCRF还必须确保在 GW的用户面 流量映射、 处理与用户的签约情况相一致, 这可以通过向 SPR获取相关 信息来实现。 对于 GPRS, PCRF必须能够支持基于 PDP上下文的策略 控制。
PDF提供授权 QoS给 GW, 随后 GW将该 QoS与 UE的 QoS请求 进行对比, 然后决定后续操作。 也就是说, 原有 GW的部分功能上移到 PCRF中去执行了。 在 PCC中, PCRF才是控制实体, 而 GW只是执行 实体。
PCC体系中, GW包含了 SBLP的 PEP和 FBC的 TPF功能, 提供 了用户面流量的策略执行和计费规则实施。 此外, PCEF还有一个反馈 功能, 也即其需要向 PCRF反馈用户面发生的事件消息。
可以看出, 无论是策略控制, 还是计费控制, 都是通过执行 PCRF 所下发的 PCC规则来实现的。 这种实施方式有利于 SBLP\FBC向 PCC 的平滑演进, 也有利于 PCC具备更广泛的适用性。
更进一步地, WiMAX 网络 R1.5版本制定的 WiMAX网络与 IMS 融合架构符合 PCC架构要求。
在 WiMAX网络中, 分为 ASN和与 CSN, ASN中物理网元有 BS、 ASN-GW, CSN中有 AAA服务器以及 PCRF功能体等。 一个 ASN-GW 与多个 BS相连, 并对这些 BS进行管理。从 QoS来说, SFM可以在 BS 上实现, 而 SFA或者 PCEF可以在 ASN-GW上实现。
在 WiMAX网络中, GW又分为锚 GW和服务 GW概念, 下面进行 解释:
当一个 MS在两个 ASN-GW之间切换时 (原来的 ASN-GW称为服 务 ASN-GW, 新的 ASN-GW称为目标 ASN-GW ), 用户会话的传输从 目标 ASN-GW到 CSN将会存在两个可能的场景, 分别如图 3的场景一 和场景二所示。
场景一: 目标 ASN-GW到锚 ASN-GW之间建立一条 R4数据通道, 用户数据由目标 ASN-GW先到锚 ASN-GW, 然后由锚 ASN-GW再到 CSN。
场景二: 目标 ASN-GW重新锚定用户会话作为新的锚 ASN-GW, 直接连接到 CSN。
这两种场景在 ASN-GW切换时都会发生。
为了明确表示 ASN内同一用户经过多个 GW的情况, 以下将提供 R3数据通道与核心网相连的 ASN-GW称为 R3 GW, 将直接与 BS相连 的 GW称为 R6 GW, R3 GW与 R6 GW可以是同一个 GW或不同的 GW。
从上述筒单叙述可以看出, 3GPP标准组织首先提出 PCC架构, 由 于 PCC架构符合基于业务流的 QoS控制与计费的网络发展趋势, 所以 越来越多的标准制定组织引进 PCC 标准作为其标准的一部分, 相应的 PCC架构原来是 3GPP制定的, 很多特性只符合 3GPP的规范, 所以这 些引进 PCC架构的各种标准组织都会对 PCC架构进行一些改进, 以使 其适应本身网络的情况。
但是, 在融合 PCC架构的网络中, 目前还没有根据 MS接入信息定 制不同的 PCC规则的方法。 更进一步地, 目前也没有根据 MS接入信息 确定策略规则的方法。 发明内容

本发明实施例还提供一种确定策略规则的系统, 该系统能够根据 MS接入信息确定不同的策略规则。

为使本发明的目的、 技术方案和优点更加清楚明白, 以下根据具体 的实施例, 并参照附图, 对本发明进一步详细说明。
当用户接入网络时, MS 的接入信息可以包括接入网络信息、 接入 区域信息或 /和基站信息。
其中, 接入网络信息可以为 NAP、 接入网标识码 ( Access Network Code )或其他能标识当前接入网络的信息。
接入区域信息在不同的网络中可以对应不同的信息, 对于 WiMAX 网络, 接入区域信息可以是接入月良务网络网关 IP ( ASN-GW IP )地址、 业务流授权者 IP ( SFA IP )地址、 外地代理 IP ( FA IP )地址、 数据通道 功能体 IP ( DP Function IP )地址等; 对于 GSM或码分多址( CDMA ) 网络, 接入区域信息可以是局部区域面积标识 (LAI, Location Area Identity )或者路由区域面积标识 ( RAI, Routing Area Identity ), 对于一 般的 IP网络而言, 接入区域信息可以是接入服务器标识(NAS ID )或 者接入服务器 IP地址( NAS IP地址)。
基站信息可以为基站标识码( BS ID )、 小区标识码( Cell ID )、 全球 小区识别码(CGI, Cell Global Identity ), BS IP地址、 或者业务流管理 者 IP ( SFM IP )地址。 其中, 在无线网络中, BS与 Cell是两个基本概 念, 下面分别介绍: BS是无线基站; Cell是基站下面的一个小区(或者 叫扇区), 一个基站 BS里可能配置成多个载频而形成的多个小区(或者 叫扇区), 也就是 BS的覆盖区域可以划分成多个小区 (或者叫扇区), 当然一个基站也可以只有一个小区。 当 MS移动的时候, 可以引发同一 个 BS不同小区 Cell之间的切换, 也就是说存在 BS不变, 但 Cell改变 的切换。
本发明实施例在融合 PCC架构的网络中, 由 PCEF上报 MS的接入 信息给 PCRE, PCRF可以根据 MS的接入信息确定不同的 PCC规则后, 下发给 PCEF执行。这样,就可以实现根据 MS接入信息确定不同地 PCC 规则。
用来实现本发明实施例的消息可以采用直径 (Diameter ) 协议, Diameter的引入是作为支持基于 IP技术的 AAA框架的 AAA协议。 Diameter协议主要功能为: 认证 ( Authentication )用户在使用网络系统 中的资源时对用户身份的确认; 授权( Authorization ) 网络系统授权用 户以特定的方式使用其资源; 计费 (Accounting) ) 网络系统收集、 记录 用户对网络资源的使用, 以便向用户收取资源使用费用, 或者用于审计 等目的。 以互联网接入业务供应商 ISP为例, 用户的网络接入使用情况 可以按流量或者时间被准确记录下来。
Diameter消息由消息头和消息体组成, 消息体部分以 AVP为单位, 每个 AVP携带了一个具体的消息参数值,每个 AVP包含 AVP头和 Data 部分。 其中, Event-Trigger AVP是一个枚举类型, 当此 AVP从 PCRF发 送到 PCEF时, 用来指示哪些事件发生后, PCEF需要重新申请 PCC规 则, 当此 AVP从 PCEF发送到 PCRF时, 其指示相应的某些事件发生。
Diameter消息包括信用控制请求(CCR ) 消息和信用控制响应消息 ( CCA ), 其中, CCR消息为客户端与信用控制服务器之间为一个业务 请求信用授权; CCA用于信用控制服务器和客户端之间确认接收到 CCR 消息。
图 4为本发明实施例确定 PCC规则的方法流程图,该方法涉及 PCC 构架中的 PCEF和 PCRF, 其具体步骤为:
步骤 401、 PCEF向 PCRF发送 PCC规则请求消息, 该消息携带 MS 接入信息。
在本发明实施例中, PCC规则请求消息可以为 CCR消息或其他消 息, MS 的接入信息为接入区域信息、 接入网络信息和基站信息中的一 种或多种组合。
步骤 402、 PCRF接收到该请求消息后, 根据携带的 MS接入信息, 结合现有机制的其他信息, 确定 PCC规则。
现有机制的其他信息为来自 AF的业务信息, 来自 SPR的用户签约 信息。
确定 PCC规则的策略可以预先设定。 例如, 预先在 PCRF设置 MS 的接入信息、 现有机制的一些信息和各个 PCC规则三者直接的对应关 系, 根据对应关系生成 PCC规则, 在 PCC规则中, 有如何进行计费、 如何对计费进行标识、 和如何控制计费等信息。
步骤 403、 PCRF向 PCEF发送 PCC规则响应消息,携带确定的 PCC 规则。 该响应消息可以为 CCA消息或其他消息。
步骤 404、 PCEF接收到该响应消息后, 执行所携带的 PCC规则。 在本发明实施例中,如果 WiMAX网络引入 PCC构架,其确定 PCC 规则的方法如图 4所述, 如果 WiMAX网络遵循的是自己标准的规划, 则如图 5所示, 涉及的网络实体包括 SFA和 PF, 可以参见的网络框架 如图 1所示, 其具体步骤为:
步骤 501、 SFA向 PF发送请求消息, 该消息携带 MS的接入信息。 该请求消息可以是策略决定 (Policy-Decision ) 消息、 资源预留 ( Resource-Reservation )消息、 位置更新 ( Location-Update )消息、 QoS 策略请求消息、 计费规则请求消息或 CCR消息等。
步骤 502、 PF根据接收到请求消息携带 MS的接入信息, 结合现有 机制的其他信息, 确定 QoS策略或 /和计费规则。
确定 QoS策略或 /和计费规则的策略可以预先设定。
现有机制的其他信息可以为来自 AF的业务信息等。
步骤 503、 PF向 SFA发送响应消息, 携带确定的 QoS策略或 /和计 费规则。
步骤 504、 SFA接收到该响应消息后, 执行所携带的 QoS策略或 / 和计费规则。
以下举具体实施例说明本发明实施例提供的方法。
实施例一到实施例三说明是如何根据 MS接入网络信息确定 PCC规 则的实施例
实施例一

在 3GPP2中, PCEF与 PCRF之间的接口为 Ty接口,所以之间的会 话称为 Ty会话, PCEF在 Ty会话建立请求消息中增加携带 MS接入网 络信息, PCRF根据接收到该消息携带的 MS接入网络信息结合现有信 息生成 PCC规则。
图 6为本发明较佳实施例一确定 PCC规则的方法流程图,其具体步 骤为:
步骤 601 ~ 602、 MS接入网络注册、 IP-CAN会话建立或者 PCEF变 化情况下, PCEF要建立与 PCRF之间的应用层会话, PCEF发送 CCR 消息给 PCRF, 请求建立应用层会话 ( Gx Session或 Ty Session ), CCR 消息中携带 MS 的接入网络信息, 该接入网络信息为 NAP或 Access Network Code。
步骤 603、 PCRF接收到该 CCR消息后, 根据现有机制的一些信息 结合携带的 MS的接入网络信息, 生成 PCC规则。
如何生成 PCC规则可以根据设置的策略决定。 例如: 预先在 PCRF 设置 MS的接入网络信息、现有机制的一些信息和各个 PCC规则三者之 间的对应关系, 根据对应关系生成 PCC规则, 在 PCC规则中, 有如何 进行计费、 如何对计费进行标识、 和如何控制计费等信息。
步骤 604、 PCRF返回 CCA消息给 PCEF , 消息中携带 PCC规则。 步骤 605、 PCEF执行接收到 CCA消息携带的 PCC规则。
实施例二
在 PCC架构中, 当 MS接入网络、 IP-CAN会话建立或者 PCEF变 换情况下, PCEF与 PCRF之间要建立 Gx Session或 Ty Session, 在建立 Gx Session或 Ty Session过程中, PCRF在会话建立响应消息里指出 PCEF 要上报 MS接入网络信息改变事件, 当 MS移动切换时引起 MS的接入 网络信息变化时, PCEF就会上报 MS接入网络信息改变事件同时上报 MS的接入网络信息, PCRF根据上报的 MS接入网络信息确定 PCC规 则后, 在响应消息中下发该 PCC规则, PCEF执行下发的 PCC规则, 图 7为本发明较佳实施例二下发上报 MS接入网络信息改变事件的方法流 程图, 其具体步骤为:
步骤 701、 当 MS接入网络、 IP-CAN会话建立或者 PCEF变换情况 下, PCEF要建立与 PCRF之间的 Gx Session或 Ty Session, PCEF发送 CCR消息给 PCRF, 请求建立 Gx Session或 Ty Session, CCR消息中携 带 MS 的接入网络信息, 该接入网络信息为 NAP或 Access Network Code。
步骤 702、 PCRF接收到该 CCR消息后, 根据现有机制的一些信息 结合携带的 MS的接入网络信息,生成 PCC规则, PCRF在 PCC规则中 指明了 PCEF需要上报 MS接入网络信息改变事件, PCRF返回 CCA 消息给 PCEF , 消息中携带 PCC规则。

即 CCR消息携带 MS信息改变事件标识以及 MS接入网络信息的更 改值。
步骤 802、 PCRF接收到该 CCR消息后, 根据现有机制的一些信息 结合携带的 MS接入网络信息的更改值, 重新生成 PCC规则。
在本发明实施例中, 重新生成的 PCC规则与 PCEF已经为 MS执行 的 PCC规则可以不同, 也可以相同, 在相同情况下, 表明 MS接入网络 信息的更改值并不影响 PCC规则,此时 PCRF收到 MS接入网络信息改 变事件标识后, 并不一定会将重新生成的 PCC规则下发。
步骤 803、 PCRF返回 CCA消息给 PCEF , 消息中携带 PCC规则。 步骤 804、 PCEF接收到 CCA消息后, 执行携带的 PCC规则。
实施例三
在本发明实施例中, WiMAX网络在与 IMS网络融合时采用 PCC架 构, 如图 9所示, 图 9为本发明实施例 WiMAX网络在与 IMS网络融合 时采用 PCC架构的示意图。
如图 9所示: 该网络包括 SFM、 SFA、 代理( Agent )、 PCRF以及 AF依次连接。 在这种架构中, WiMAX网络引入了 Agent功能体, 此功 能体的引入主要是为了不改变原有 PCC架构的 Gx接口, PCEF与 PCRF 之间的 Gx接口是不支持移动性的,即在一次 IP-CAN会话过程中, PCEF 与 PCRF都是不会移动的, 两者之间 Gx会话一直保持。 当 WiMAX网 络引入 PCC构架时, 将 PCEF放到 ASN-GW (在图中为 SFA ) 实体实 现, 而对于同一 MS而言, 随着 MS的移动, ASN-GW是会改变的, 为 了不改动现有 PCC构架而又适应 WiMAX网络特点, 所以提出了 Agent 这个功能体, 此功能体的主要作用是转发 Gx接口消息, 屏蔽 SFA的变 化, 即屏蔽 ASN-GW的变换, Agent与 SFA之间有一个接口称之为 R3 或者 R3-PCC接口, 与 PCC构架的 Gx接口不同的是 R3或者 R3-PCC 接口允许在一次 IP-CAN Session 过程中 PCEF 可以发生变化。 通过 Agent, 可以实现: Agent与 PCRF之间使用现有的 Gx接口, 在 PCRF 看来, Agent就是一个不会移动的 PCEF, 同时 Agent与 SFA之间使用 R3或者 R3-PCC接口, SFA是实质上执行 PCC规则的实体, SFA可以 移动变化。 从高层次的角度来看, 可以将 SFA与 Agent共同看作是一个 PCEF, 这样就完全符合原 PCC架构的规定。

步骤 1001、 SFA发送 CCR消息到 Agent, 指示 R3 Session或者 R3-PCC Session建立, CCR消息携带 MS的接入网络信息。
在本发明实施例中, SFA也可以发送携带 MS的接入网络信息的其 他消 息, 用 于替代 CCR 消 息, 如 Policy-Decision 消 息、 Resource-Reservation消息、 Location-Update消息、 QoS策略请求消息、 或计费规则请求消息等, 只要是 SFA与 Agent之间的承载消息即可。
