Description

一种动态策略控制下计费实现方法和系统
技术领域 本发明涉及通信领域， 具体而言， 涉及一种动态策略控制下计费实现方 法和系统。
背景技术 码分多址接入 2000 ( Code Division Multiple Access 2000 , 简称为 CDMA2000 ) 网络可以使用简单因特网协议（ Simple Internet Protocol , 简称 为简单 IP ) 、 移动因特网协议（ Mobile Internet Protocol , 简称为 MIP )或代 理移动因特网协议（ Proxy Mobile Internet Protocol , 简称为 ΡΜΙΡ )作为其网 络通信协议。 图 1是釆用 ΜΙΡ协议的 CDMA2000参考模型，其中，无线接入网络（ Radio Access Network, 简称为 RAN ) 包括分组控制功能 ( Packet Control Function, 简称为 PCF )和无线资源控制 （Radio Resource Control, 简称为 RRC ) ； 核 心网络的电路交换部分负责用户话音呼叫的实现， 其包括移动交换中心 ( Mobile Switching Center, 简称为 MSC )和归属位置寄存器（ Home Location Register, 简称为 HLR ) ； 支持分组数据业务的核心网络分组交换部分负责 用户数据业务的实现， 其包含分组数据服务网络 （Packet Date Service Network, 简称为 PDSN )和认证授权计费（ Authentication Authorization and Accounting, 简称为 AAA )。 此外外地代理 ( Foreign Agent, 简称为 FA )位 于本地网络， 可以为终端分配转交地址（Care of Address, 简称为 CoA ) , 为终端提供本地接入， 同时完成终端和归属代理（Home Agent, 简称为 HA ) 之间的 MIP注册， 在 FA和 HA之间 , 或者终端和 HA之间建立 MIP隧道。 在 CMDA2000网络中， FA的功能可以集成于 PDSN。 HA位于归属网络， 用于维护终端的位置信息， 为终端分配归属 IP地址， 并且响应终端的 MIP 注册请求， 维护 CoA和归属地址（Home Address, 简称为 HoA ) 的映射。 釆用 MIP技术的网络可以支持网络主动发起的业务，并且可以保证终端在发 生接入切换过程中（即发生跨 PDSN切换），正在开展的业务不会发生中断， 保证业务的连续性。 釆用 PMIP协议的 CDMA2000网络的网络参考模型与图 1类似。 其中 FA和 HA分别被移动接入网关 （ Mobile Access Gateway, 简称为 MAG )和 本地移动锚点（ Local Mobility Anchor, 简称为 LMA )功能网元所取代。 LMA 网元的位置相当于 HA, 也是负责为终端分配归属 IP地址， 同时在终端的 PMIP注册过程中， 负责维护 CoA和 HoA的绑定关系。 MAG功能主要为终 端提供本地接入， 在 PMIP网络中， MAG功能可以集成于 PDSN。 PMIP网 络和 MIP网络的区别在于， MIP网络中的 CoA可以分配给终端也可以分配 给 PDSN, 而 PMIP网络中的 CoA只能分配给 PDSN, 而终端只需要 HoA就 可以开展业务， 即 PMIP网络下， 终端不需要感知自己是否发生了跨 PDSN 的切换。 对于 CDMA2000网络， 如果终端开展业务， 首先需要和 PDSN之间建 立点对点协议（Point to Point Protocol, 简称为 PPP )会话。 如果 PPP会话建 立成功， 则在终端和 PDSN之间建立了主服务连接。 该主服务连接主要用于 传输信令控制流， 也可用于传输需要尽力而为 （best effort )方式的业务数据 流。 另外， 为了满足对开展的业务实施区分服务质量（Quality of Service, 简 称为 QoS )保证的需要，还可以在终端和 PDSN之间建立多个辅助服务连接， 用以承载具有不同 QoS需求的业务数据流。 在没有引入动态策略控制机制情况下， CDMA2000网络定义了由 PDSN 收集计费信息， 并和 AAA交互的基于用户的计费实现方式。 其计费控制过 程如下： 对于主服务连接上的 IP流实现基于服务连接的计费，在主服务连接 建立成功之后， PDSN将收集的基于服务连接的计费信息发送给 AAA, 启动 计费过程， 同样在主服务连接释放的时候， PDSN需要和 AAA交互， 终止计 费过程。 而对于辅助服务连接上的 IP流可以实现基于服务连接或者基于 IP 流的计费， 在辅助服务连接建立成功之后或者在业务数据流激活时候， 由 PDSN收集计费信息， 并发送给 AAA, 启动和业务相关的计费过程。 在业务 数据流终止后或者在辅助服务连接释放后， 终止计费过程。 其控制方式取决 于运营商在 PDSN上配置的策略。 随着入网用户的增加， 以及网络上开展的业务越来越丰富， 用于为业务 传输提供 QoS保证的网络资源正变得日趋紧张。传统的通过预配置等粗放型 的资源管理方式已不能满足运营需求。 为了提高资源管理效率， 需要在网络 中引入动态策略控制机制。 动态策略控制机制可以根据网络上的业务开展情 况， 实时的分配或者释放网络资源， 并实现灵活的计费。 第三代合作伙伴计 划（ 3rd Generation Partnership Project, 简称为 3GPP )定义了针对移动网络的 策略和计费控制 （Policy and Charging Control, 简称为 PCC ) 架构， 包括： 策略和计费规则功能 (Policy and Charging Rules Function, 简称为 PCRF ) 、 策略和计费执行功能 ( Policy and Charging Enforcement Function, 简称为 PCEF )、承载绑定和事件上报功能（ Bearer Binding and Event Report Function, 简称为 BBERF )和用户签约数据库（ Subscription Profile Repository, 简称为 SPR ) 。 其中， PCRF 可以根据动态业务信息、 用户签约信息 （例如从 SPR 获取)和运营商策略等信息对业务使用网络资源制订实时的控制和计费策略。
PCEF和 BBERF用于实时的执行 PCRF下发的 QoS控制策略， 对业务数据 流使用网络资源进行实时的分配和释放， 此外 PCEF还要根据 PCRF下发的 计费策略实时的对业务数据流进行计费控制， 完成和在线计费系统（Online Charging System, 简称为 OCS )或者离线计费系统（ Offline Charging System, 简称为 OFCS ) 关于计费信息的交互。 动态策略控制机制定义了动态的 QoS 资源管理方式， 以及由 PCEF和 OCS或者 OFCS交互的基于流的动态计费方式。运营商一方面希望网络引入 动态策略控制机制， 借助其提高网络资源管理效率， 另一方面考虑到节约投 资成本， 运营商还希望利用原有的计费系统和计费方式。

616, 当建立了与业务数据流传输所需 QoS保证相一致的辅助服务连接， 并启动门控之后， MS就可以开展业务。 AAA根据计费启动消息， 对业务实 施相应的计费。 上述实施例描述的是釆用 MIP协议的 CDMA2000引入 PCC之后， 计费 实施过程。 其中由 HA收集计费信息， 并在门控启动后， 通过扩展 MIP消息 将计费信息和门控启动事件发送 AAA, 和 AAA进行计费交互， 启动针对业 务实现基于用户的计费过程。
实施例 5 实施例 5描述了釆用 PMIP协议的 CDMA2000网络引入动态策略控制机 制之后的传统和 AAA交互方式的计费实现过程。 其计费信息由 LMA收集， 并和 AAA交互， 如图 7所示， 包括：
701 , MS附着到网络， 和 PDSN之间进行 LCP协商， 包括协商鉴权所 使用的协议等。
702, MS、 PDSN和 AAA之间完成鉴权过程。
703 , 鉴权成功之后， AAA将用户签约信息下发给 PDSN, PDSN将部 分用户签约信息下发给 RAN。
704 , MS向 PDSN发起 IPCP配置请求。
705 , PDSN向 h-PCRF发起请求， 建立网关控制会话。
706, PDSN向 LMA发送 PMIP注册请求。
707, LMA收到 PMIP注册请求消息后 , 和 h-PCRF之间建立 IP-CAN会
708, LMA向 PDSN返回 PMIP注册响应。
709 , PDSN向 MS返回 IPCP配置响应消息。
710, LMA向 AAA发送针对主服务连接的计费启动消息， 开始计费。
711 , MS启动网络注册过程， 例如 MS注册到 IMS网络。
712, MS开始业务， 完成和网络之间的应用层业务协商， 包括开展的业 务包含的业务数据流、 所需的带宽、 所使用的编解码等。 713 , 根据应用层协商的结果， MS发起和网络之间用于承载业务数据流 的辅助服务连接的建立过程。 包括在 MS和 RAN之间建立辅助无线连接， 在 RAN和 PDSN之间建立对应的辅助 A10连接。
714 , MS 通过 RSVP 消息， 将业务数据流对应的请求 QoS (以 FlowProfilelD表示 )和用于匹配业务数据流的 TFT发送给 PDSN。 715, PDSN接收请求消息之后， 完成 QoS的映射， 向 h-PCRF请求对业 务数据流的请求 QoS进行授权。
716, h-PCRF从 AF获取业务协商信息。
717, h-PCRF根据业务协商信息和用户签约信息等， 为请求 QoS进行授 权决策。 718, h-PCRF将授权 QoS以 QoS规则的形式下发给 PDSN执行。
719, PDSN完成授权 QoS的映射， 并通过 ResvConf消息将授权 QoS以 授权 FlowProfilelD的形式下发给 MS。
720, h-PCRF根据步骤 517的授权结果向 LMA发起 IP-CAN会话修改 的请求， 将授权策略下发给 LMA。 721 , LMA执行策略， 向 h-PCRF返回 IP-CAN修改的响应。
722, 如果授权 FlowProfilelD描述的授权 QoS与第 713步辅助服务连接 建立过程中使用的授权 QoS不一致， 则 MS使用授权 FlowProfilelD发起对 已经建立的辅助服务连接的 QoS进行修改， 并开启门控。
723 , PDSN启动门控之后 , 通过向 LMA发送扩展的 PMIP消息 , 消息 中包含门控启动信息和计费， 触发 LMA启动门控， 并实施计费。 例如所述 门控启动事件可以通过流状态设置开启 （ flow status = open )表示。
724, LMA收到门控启动信息和计费信息之后，向 PDSN返回扩展 PMIP 响应消息。
725, LMA将计费信息， 通过计费启动请求消息发送给 AAA, 启动针对 业务的计费过程。
726, 当建立了与业务数据流传输所需 QoS保证相一致的辅助服务连接， 并启动门控之后， MS就可以开展业务。 H-AAA根据计费启动消息， 对业务 实施相应的计费。 上述实施例描述的是釆用 PMIP协议的 CDMA2000引入 PCC之后， 计 费实施过程。 其中由 LMA通过扩展的 PMIP消息从 PDSN收集计费信息， 并在收到门控事件之后和 AAA进行计费交互， 启动针对业务的计费过程。 釆用 PMIP协议的 CDMA2000的其他计费场景与实施例 1 - 4相似， 这里不 再描述。 本发明还提供一种动态策略控制下计费实现系统，其包括归属代理（ HA ) 或本地移动锚定（LMA ) ， 其设置为： 收集计费信息， 将所述计费信息发送 给 AAA, 从而实现计费控制交互过程。 其中， 所述 HA或 LMA是设置为通过 PCRF从 PDSN获取计费信息， 或者 HA通过扩展 MIP协议， LMA通过扩展 PMIP协议从 PDSN获取计费 信息。 其中， 所述 HA或 LMA是设置为在收到 PCRF下发的控制策略信息后， 将计费信息发送给 AAA, 实现计费控制交互过程； 或者在收到门控事件后， 将计费信息发送给 AAA, 实现计费控制交互过程。 其中， 所述 HA或 LMA是设置为通过 PCRF从 PDSN接收所述门控事 件， 或者， HA通过扩展 MIP协议， LMA通过扩展 PMIP协议从 PDSN接收 所述门控事件， 所述门控事件是门控打开或者门控关闭。
以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
工业实用性 本发明将 PDSN的计费功能转移到 HA或 LMA上， 实现了 PCC与传统 计费方式的结合。
