Description

一种获取用户标识的方法和系统 技术领域
本发明涉及微波接入全球互通( WiMAX, Worldwide Interoperability for Microwave Access )技术领域, 尤其涉及一种在 WiMAX网络中的策 略与计费控制 (PCC, Policy and Charging Control )框架下获取用户标 识的方法和系统。 背景技术
现有的微波接入全球互通 (WiMAX , Worldwide Interoperability for Microwave Access ) 网络通常由三部分组成: WiMAX终端 (筒称为终端、 或移动台 /固定台)、 接入业务网络(ASN, Access Service Network )和连接 业务网络(CSN, Connect Service Network ), 如图 1所示。
其中, ASN主要完成以下功能: 完成终端的二层(L2 )连接、 传递认 证授权计费 ( AAA, Authentication Authorization Accounting ) 消息到归属 CSN ( H-CSN , Home-CSN )、 网络业务提供商 (NSP , Network Service Provider ) 的网络选择与发现、 为终端的三层( L3 )连接提供中继、 无线资 源管理、 ASN与 CSN之间的隧道维护。 移动场景下, ASN还需要支持如 下功能: ASN锚定的移动性管理(ASN Anchored MM )、 CSN锚定的移动 性管理(CSN Anchored MM )、 寻呼(Paging )和空闲 (Idle )模式的操作。
CSN是一套网络功能的组合, CSN可以由移动 IP的家乡代理(HA, Home Agent )、 AAA代理( AAA Proxy )或 AAA月良务器( AAA Server )、 计 费服务器、 互连网关设备等组成。 CSN由 NSP管理, CSN主要完成如下功 能: 终端用户的会话连接、 终端的 IP地址分配、 互联网 (Internet )接入、 AAA代理或 AAA服务器、终端用户的策略及许可控制、 ASN与 CSN之间 的隧道维护、 终端用户的计费和结算、 CSN间的漫游、 CSN间的移动性管 理和 WiMAX业务。
为了更为灵活的动态服务质量(QoS, Quality of Service ) 的控制、 计 费策略控制等, WiMAX 网络引入了策略与计费控制 (PCC, Policy and Charging Control )框架, 如图 2所示。 在 WiMAX PPC框架中, 主要包含 以下几个重要的功能实体:
A-PCEF/C-PCEF:策略及计费执行功能实体( PCEF, Policy and Charging Enforcement Function ), 属于策略执行点, 通过 PCC消息交互, 与策略及计 费规则功能实体( PCRF, Policy and Charging Rules Function )一起维护 IP 连接访问网络(IP-CAN, IP-Connectivity Access Network )会话 ( IP-CAN Session, IP-CAN会话是终端与 IP网络之间的联合, 这种联合通过用户 IP 地址标识; 一个 WiMAX的 IP-CAN会话在终端获取到 IP地址建立, 在终 端释放 IP地址后释放此会话)。其中, 前缀 "A-"是指 ASN网络中的 PCEF, "C-"是指 CSN网络中的 PCEF。 PCRF下发的策略包括计费策略由 PCEF 执行;
策略分发实体(PDF, Policy Distribution Function ): 主要负责策略的分 发到 A-PCEF和 C-PCEF;
PCRF: 是服务数据流和 IP承载资源的策略及计费控制策略决策点, 为 PCEF选择及提供可用的策略和计费控制决策;
签约用户资料库(SPR, Subscription Profile Repository ): 存放签约用 户的策略及 IP-CAN承载相关的 PCC规则等;
PCRF与 SPR之间通过 Sp参考点连接, 通过 Sp参考点可以基于用户 标识查询 SPR中签约用户相关 PCC规则信息。
现有技术中, 一次 IP-CAN会话建立的过程, 如图 3所示, 主要包括以 下步骤: 步骤 301 , 用户接入 WiMAX网络并分配到 IP地址后, 触发 A-PCEF 发起 IP-CAN会话的建立。
步骤 302, A-PCEF向 PCRF发送 IP-CAN会话建立指示, 该指示消息 中包含用户的 IP地址、 用户标识等。
步骤 303, PCRF向 SPR发送用户规则策略请求消息, 请求获取相关 PCC规则 /策略。
步骤 304, SPR基于用户标识查询签约用户信息, 向 PCRF返回用户规 则策略响应消息, 其中包含用户相关策略信息。
步骤 305 , PCRF基于 SPR的响应消息进行策略决策。
步骤 306, PCRF向 A-PCEF发送 IP-CAN会话建立响应消息。
步骤 307, A-PCEF通知用户 IP-CAN会话建立完成。
在上述步骤 302~304 中, 涉及到基于用户标识查询用户的 PCC规贝' J/ 策略( PCC Profile )信息, 在 WiMAX网络中, 用户标识为网络接入标识符 ( NAI, Network Access Identifier ), 用户签约的真实标识一般称之为真实 NAI ( inner- NAI ), 如: usemame@wimaxfomm.org; 而在用户接入 WiMAX 网络时, 为了用户信息安全, 终端会构造一个伪 NAI用于网络中其他网元 标识用户,一般称之为伪 NAK outer-NAI ),如: 11223344@wimaxfomm.org, 如图 4所示。 用户的真实 NAI和伪 NAI之间的对应关系只有终端和 AAA 服务器了解, PCEF只能获取到用户的伪 NAI, 相应的, PCRF也只知道用 户的伪 NAI; SPR在签约用户 PCC相关策略信息时是不会基于一个临时的 伪 NAI来标识, 这个用户标识应该是个真实的用户标识。
在上述步骤 303中 PCRF向 SPR请求策略信息时是使用的伪标识, 而 SPR中签约用户 PCC信息时是基于真实标识的, 这样就无法找到对应用户 的策略信息。 针对上述问题, 现有技术还没有提出有效的解决方案。 发明内容

步骤 604, SPR向 AAA服务器发送接入请求, 请求获取用户的真实标 识( inner NAI ), 而该接入请求中包含的是用户的伪标识( outer NAI )。
步骤 605 , AAA服务器向 SPR发送接入响应, 其中包含用户的真实标 识。
AAA服务器根据接入请求中的伪标识, 查询自身保存的用户伪标识和 真实标识的映射关系, 并将查询到的与接入请求中的伪标识相对应的真实 标识通过接入响应发送给 SPR。
步骤 606 , SPR基于用户真实标识查询用户签约的策略信息,并向 PCRF 返回用户规则策略响应消息, 其中包含查询所得用户签约的策略信息。
步骤 607, PCRF基于 SPR的响应消息中包含的策略信息进行策略决策。 步骤 608 , PCRF向 A-PCEF发送 IP-CAN会话建立响应消息。
步骤 609 , A-PCEF通知 IP-CAN会话建立完成。
对应上述获取用户标识的方法, 本发明还提供了一种获取用户标识的 系统, 包括: PCRF、 SPR和 AAA服务器。 其中, PCRF用于在 IP-CAN会 话建立的过程中, 向 AAA服务器请求用户的真实标识; 或者, SPR用于在 IP-CAN会话建立的过程中, 向 AAA服务器请求用户的真实标识。 AAA服 务器, 用于根据来自 PCRF的请求, 向 PCRF返回用户的真实标识; 或者, 根据来自 SPR的请求, 向 SPR返回用户的真实标识。
较佳的, PCRF进一步用于, 向 AAA服务器发送接入请求, 该请求中 包含用户的伪标识; 相应的, AAA服务器进一步用于, 根据接入请求中的 伪标识, 查询自身保存的用户伪标识和真实标识的映射关系, 并将查询到 的与接入请求中的伪标识相对应的真实标识通过接入响应发送给 PCRF。在 AAA服务器向 PCRF返回用户的真实标识后, PCRF向 SPR发送用户规则 策略请求消息, 该请求消息中包含用户的真实标识; 相应的, SPR服务器 根据用户的真实标识查询用户相关的策略信息, 并将查询到的策略信息通 过用户规则策略响应消息发送给 PCRF。
较佳的, SPR进一步用于, 在接收到来自 PCRF的用户规则策略请求 消息后, 向 AAA服务器发送接入请求, 该接入请求中包含用户的伪标识; 其中, 策略请求中也包含用户的伪标识; 相应的, AAA服务器进一步用于, 根据接入请求中的伪标识, 查询自身保存的用户伪标识和真实标识的映射 关系, 并将查询到的与接入请求中的伪标识相对应的真实标识通过接入响 应发送给 SPR。 在 AAA服务器向 SPR返回用户的真实标识后, SPR根据 用户的真实标识查询用户相关的策略信息, 并将查询到的策略信息通过用 户规则策略响应消息发送给 PCRF。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
