Description

一种多播广播业务的计费方法及装置 本申请要求于 2008年 11月 5日提交中国专利局、 申请号为 200810217255. 8、发明 名称为 "一种多播广播业务的计费方法及装置"的中国专利申请的优先权， 其全部内容 通过引用结合在本申请中。 技术领域 本发明属于通信技术领域， 尤其涉及一种多播广播业务的计费方法及装置。 背景技术
WiMAX ( Worldwide Interoperability for Microwave Access,全球接入微波互操作性） 是一种基于 IEEE802.16 标准的无线城域网技术。 WiMA 网络无线侧是基于 IEEE802.16d/e标准的无线城域网接入技术，采用 OFDM (Orthogonal Frequency Division Multiplexing, 正交频分复用技术）禾 B OFDMA (OFDM Access, OFDM接入） 的物理层 技术， 能有效的抗多径衰落。 最佳信道衰落情况下， 传输速率可以逼近 75Mbps。
WiMA 网络逻辑架构如图 1所示， WiMA 整个网络主要由以下三部分组成： ( 1 )终端： 包括 SS ( Subscriber Station, 用户台）或 MS (Mobile Station, 移动台）， 终端使用该设备接入 WiMA 网络。
(2) 接入业务网： ASN (Access Service Network, 接入业务网） 定义为 WiMAX 终端提供无线接入服务的网络功能集合。 ASN包含了 BS(Base Station,基站）和 ASN-GW (ASN Gateway, ASN网关） 网元。 其中 BS网元的主要功能为： 提供 BS和 MS的 L2 连接、 无线资源管理等等； ASN-GW网元的主要功能为： 为 MS认证、 授权和计费功能 提供客户端功能， 为 MS提供 L3信息的 Relay功能（如 IP地址分配）、 ASN内切换等。
( 3 )连接业务网： CSN ( Connectivity Service Network,连接业务网）定义为 WiMAX 终端提供 IP连接服务。 CSN主要包括包括预付费服务器以及认证、 授权和计费服务器 等逻辑实体， 所提供的主要功能为： MS的 IP地址分配、 Internet接入、 AAA proxy或 者 serve 基于终端的授权控制等。
人们通常所说的通信是在一个节点和另外一个节点之间的通信，但是随着用户需求 的增加， 以及多种媒体的引入， 用户需要进行一对多或多对多的通信， 从而产生了点到 多点 （Point to Multipoint, 简称 " PTM") 的传输模式。 为了在移动网上支持这些模式， 实现一对多的多播广播业务， 同时为了有效地利用移动网络资源， 现有技术在 WiMAX 的基础上定义了 MBS (Multicast Broadcast service 多播广播业务） 业务。 MBS 业务 是在移动网络中提供一个数据源向多个用户发送数据的点到多点业务， 实现网络资源共 享， 提高网络资源的利用率， 尤其是空口接口资源。 WiMA 定义的 MBS不仅能实现 纯文本低速率的消息类多播和广播， 而且还能实现高速多媒体业务的多播和广播， 这无 疑顺应了未来移动数据发展的趋势。
基于 WiMAX网络的 MBS业务支持两种接入模式： 单基站接入和多基站接入。 在 多基站接入模式下， 定义了 MBS域（即 MBS Zone, 用 MBS_zone ID来标识） 的概念， 所谓一个 MBS 域就是多个基站组成的集合， 一个 MBS 域内的所有基站用相同的 Multicast CID和 MBS组安全联盟（MBS Group Security Association,简称" MBS GSA")， 发送同一 MBS业务流的内容， 注册了 MBS服务的终端可以在该 MBS域内通过多个基 站接收 MBS业务数据，并且处于空闲态的终端在 MBS域内跨基站移动时，不需重建连 接， 可以不受影响的接收 MBS业务， 实现 MBS业务的无缝切换。 单基站接入 MBS是 多基站接入 MBS的一种特例， MBS域范围限定为一个基站覆盖范围内， 一个 MBS域 内接收该 MBS的所有用户使用同一个多播连接标识。
目前， 现有技术中没有定义如何对 WIMA 网络中的 MBS业务进行计费， 如果采 用现有的单播业务的计费方法对多播业务进行计费， 会形成大量的数据传输， 对 ASN 网络造成很大的冲击， 影响整个网络性能。 发明内容 本发明实施例提供一种多播广播业务的计费方法及装置， 以实现对 MBS业务的计 费。

本发明实施例在现有的 WIMAX网络中， ASN内设置一个 MBS网关， 该 MBS网 关包括 MBS Proxy MBS DPF( MBS Datapath Function)、MBS计费代理（MBS Accounting Agent) , 目前 WIMAX网络有两者网络结构， 如果按照 Profile A或 C部署， 如图 2所 示， ASN包括 BS和 ASN GW, ASN GW中包括 Anchor SFA (锚定服务流授权）、 Accounting Client (计费客户端） 禾 B Authenticator (鉴权器）， MBS网关与 ASN GW之 间通过 R4接口连接； 如果按照 Profile B部署， 如图 3所示， ASN内不区分 BS和 ASN GW, ASN中包括 Anchor SFA、 Accounting Client和 Authenticator, MBS网关与 ASN 之间通过 R4接口连接。
MBS DPF为 MBS数据通路功能，它是 CSN向 ASN提供 MBS业务时的 ASN数据 入口；
MBS Proxy为 MBS代理服务器， 它提供 MBS业务信令面功能， 负责处理 MBS服 务器与 MS、 ASN的 MBS业务信令处理和转发， 与 MBS DPF位于同一网元上；
MBS Accounting Agent为 MBS计费代理， 它负责收集 MBS业务的计费信息， 与
MBS DPF位于同一网元上。
CSN内的计费服务器可能是单独的一个网元， 也可能位于 AAA (Authentication, Authorization, Accounting, 鉴权授权计费） 服务器上， 计费服务器与 ASN或 ASN GW 之间通过 R3接口连接。
本发明实施例所述多播广播业务的计费方法， 采取的技术方案为：
ASN接收 MBS计费代理发送的 MBS业务计费信息，所述计费信息包括 MBS业务 标识和 MBS业务粒度计费信息；
根据本地维护的终端 MS的上下文信息， 以及接收到的所述 MBS业务标识和 MBS 业务粒度计费信息， 生成基于用户业务粒度的计费信息， 并将生成的计费信息发送给计 费系统。
参考图 4， 本发明实施例一所述 MBS业务的计费方法包括：
401、 MBS计费代理的以业务粒度收集 MBS业务计费信息， 并向 MBS业务的计费 客户端所在的 ASN发送所述计费信息；
计费信息中包括 MBS业务标识和 MBS业务粒度的计费信息， 所述 MBS业务标识 可以是业务 ID、 业务名称、 业务类型、 多播 IP (Multicast IP)地址、 MBS Zone ID (多 播广播业务域标识）、 MCID (Multicast Connection ID, 多播连接标识） 中的至少一种， 用于标识具体 Zone内的业务，所述业务粒度的计费信息可以为所发送的 MBS业务流量 或 MBS业务时间等。
所述 MBS业务的计费客户端所在 ASN指的是当前 MBS Zone内的所有 ASN，或者 该 MBS Zone内所有具有计费客户端功能的 ASN，或者该 MBS Zone内所有接受该 MBS 业务的 MS的计费客户端所在的 ASN。
MBS计费代理可周期性的收集 MBS业务计费信息， 并周期性的向 MBS业务的计 费客户端所在的 ASN发送所述计费信息，如果是 Profile B，则 MBS计费代理向 ASN GW 发送所收集的计费信息，本申请中， MBS计费代理向 ASN或 ASN GW发送计费信息统 一称为向 ASN发送计费信息。 所述业务粒度的计费信息可以为当前周期所发送的 MBS 业务流量或 MBS业务时间等。 402、 ASN根据所述 MBS业务标识确定使用 MBS业务的终端 MS， 生成所述 MS 的基于用户业务粒度的计费信息， 并将生成的计费信息发送给计费系统。
ASN可根据本地维护的 MS的上下文信息， 查找当前使用该 MBS业务的 MS， 并 将收到的计费信息加入该 MS的标识， 生成该 MS的基于用户业务粒度的计费信息， 并 发送给计费系统；
ASN中（或 ASN GW)的鉴权器根据 MBS业务标识，检索本地维护的 MS上下文， 若某个上下文表明有 MS正在使用这个 MBS业务， 则触发该 MS的计费客户端进行计 费处理， 具体为： MS 的计费客户端将来自 MBS计费代理的业务粒度计费信息将计费 信息中加入 MS标识信息， 该 MS的标识信息可以为 MS的 NAI、 MS的 MAC地址、 MS的 IP地址或业务订阅用户标识中至少一项， 生成基于用户业务粒度的计费信息， 将 根据计费策略生成的计费信息发送给计费系统；
上述步骤中，可以找到使用 MBS业务的各个 MS，则 MS的计费客户端将所述 MBS 业务粒度计费信息中分别加入各个 MS的标识信息， 生成各个 MS的用户业务粒度的计 费信息， 并将生成的计费信息发送给计费系统。
计费系统可根据收到的基于用户业务粒度的计费信息对使用该 MBS业务的用户进 行计费， 计费过程为现有技术， 不再赘述。
403、 ASN向 MBS计费代理返回确认消息， 通知 MBS计费代理之前所发送的计费 信息已被接收；
步骤 403为可选步骤， 可在收到计费信息后立即执行， 即步骤 403与步骤 402可并 发进行， 没有严格的执行顺序。
本发明实施例二中 MBS业务的计费方法与实施例一不同之处在于， MBS计费代理 不主动向 ASN发送计费信息， 而是在接收到 ASN发送的计费请求后， 再将收集到的计 费信息上报到 ASN， 参考图 5， 包括：
501、 ASN向 MBS计费代理发送计费请求消息；
所述计费请求消息可以中携带有 MBS的业务标识，所述 MBS业务标识可以是业务
ID、 业务名称、 业务类型、 多播 IP (Multicast IP) 地址、 MBS Zone ID (多播广播业务 域标识）、 MCID (Multicast Connection ID, 多播连接标识） 中的至少一种， 用于标识具 体 Zone内的业务； ASN可周期性的向 MBS计费代理发送计费请求消息。 502、 MBS计费代理的以业务粒度收集 MBS业务计费信息， 并向 MBS业务的计费 客户端所在的 ASN发送所述计费信息；
计费信息中包括 MBS业务标识和 MBS业务粒度计费信息，所述业务粒度的计费信 息可以为所发送的 MBS业务流量或 MBS业务时间等。
503、 ASN根据本地维护的 MS的上下文信息， 查找当前使用该 MBS业务的 MS， 生成该 MS的基于用户业务粒度的计费信息， 并发送给计费系统；
该步骤同 402类似， 不再赘述， 并且， 进一步的， ASN可以向 MBS计费代理返回 确认消息。
实施例三， MBS 计费代理在周期性上报计费信息的过程中， 即， 在实施例一或实 施例三方法过程中， 如果有新的 MS加入 MBS业务， MBS计费代理需要向 MS的计费 客户端上报该 MS的计费信息； 参考图 6， 该方法包括：
601、 MS的 Anchor SFA检测到为 MS提供 MBS业务的触发事件发生，例如： AAA 服务器根据用户的签约信息触发 Anchor SFA为用户提供 MBS业务，或者用户主动发起 IGMP JoinClGMP加入）过程， Anchor DPF检测到此消息后再通知到 Anchor SFA, Anchor SFA在业务完成授权后， 为用户提供对应的 MBS业务等；
602、 Anchor SFA向 MBS Proxy发送 MBS请求， 现有技术中该请求用于获取 MBS 的接入网参数， 例如 MCID (Multicast CID, 多播 CID)、 LCID (Logical CID,逻辑 CID) 等； 本实施例中， 可以在该请求消息中增加计费指示， 用于要求提供计费信息； 在另一 实施例中， MBS请求可以不携带计费指示， 但计费代理收到该 MBS请求后也同样上报 计费信息。
603、与 MBS Proxy位于同一网元的 MBS计费代理以业务粒度收集当前的 MBS业 务计费信息， 并提供给 MS的计费客户端， 计费信息为 MBS业务粒度的计费信息， 还 可包括 MBS业务标识，所述当前 MBS业务粒度计费信息可以为本周期内已发送的 MBS 业务流量或时间等信息， 所述计费客户端与 MS的 Anchor SFA位于同一网元 （ASN或 者 ASN GW)。 MBS Proxy与 MBS计费代理位于同一网元，它们之间的调用属于现有技 术， 这里不再赘述。
604、 MS的计费客户端将收到的计费信息转化为该 MS的用户业务粒度的计费信息， 具体为： MS的计费客户端将所述 MBS业务粒度计费信息加入 MS的标识， 生成基于该 MS的用户业务粒度的计费信息， 发送给计费系统。
在后续的下一个周期性计费过程中，计费系统还将收到按照实施例一或实施例二得 到的该新加入 MS在这个计费周期内所使用的 MBS业务流量或时间， 则计费系统将这 个周期内的 MBS业务流量或时长，减去 MS新加入时获得的该周期内已发送的 MBS业 务流量或时间， 即可得到该周期内新加入 MS实际接收到的 MBS业务流量或时间。
实施例四， MBS 计费代理在周期性上报计费信息的过程中， 即， 在实施例一或实 施例三方法过程中， 如果有 MS退出 MBS业务， MBS计费代理需要向 MS的计费客户 端上报该 MS的计费信息； 参考图 7， 该方法包括：
701、 MS的 Anchor SFA检测到终止某 MS的 MBS业务的触发事件发生， 例如： AAA服务器根据用户的签约信息通知 Anchor SFA不再为该 MS提供 MBS业务； 或者 用户主动发起 IGMP leave (IGMP退出） 过程， Anchor DPF检测到此消息后再通知到 Anchor SFA, Anchor SFA完成授权后， 为用户撤销对应的 MBS业务； 或者终端发起的 DSD (Dynamic Service Deleting, 动态服务流删除） 过程， Anchor SFA完成授权后， 为 用户撤销对应的 MBS业务。
702、 MS的 Anchor SFA向 MBS Proxy发送终止 MBS业务请求消息， 用于请求终 止 MBS业务；本发明实施例可以在该请求中增加计费指示，用于请求 MBS业务的计费 信息， 同步骤 602类似。
703 与 MBS Proxy位于同一网元的 MBS计费代理以业务粒度收集当前的 MBS业 务计费信息， 并提供给 MS的计费客户端， 计费信息中包括 MBS业务粒度的计费信息， 还可包括 MBS业务标识， 所述当前 MBS业务粒度计费信息可以为本周期内已发送的 MBS业务流量或时间等信息，所述计费客户端与 MS的 Anchor SFA位于同一网元（ ASN 或者 ASN GW) o
704、 MS的计费客户端将计费信息转化为该 MS的用户业务粒度的计费信息， 具体 为： MS的计费客户端将所述 MBS业务粒度计费信息加入 MS的标识， 生成基于该 MS 的用户业务粒度的计费信息， 发送给计费系统， 以使得计费系统对该退出 MBS业务的 用户进行计费。
实施例五，本实施例 MBS计费代理不周期性上报，仅在终端加入和退出 MBS业务 时， MBS计费代理向 ASN (ASN GW)上报当前已发送的流量数， MS的计费客户端或 计费系统根据加入和退出时流量之差获得 MS实际使用的流量数， 参考图 8， 该方法包 括-
801、 MS的 Anchor SFA检测到为新加入的 MS提供 MBS业务的触发事件发生，例 如： AAA服务器根据用户的签约信息触发 Anchor SFA为用户提供 MBS业务， 或者用 户主动发起 IGMP Join C lGMP加入）过程， Anchor DPF检测到此消息后再通知到 Anchor SFA, Anchor SFA在业务完成授权后， 为用户提供对应的 MBS业务。
802、 Anchor SFA向 MBS Proxy发送 MBS请求， 现有技术中该请求用于获取 MBS 的接入网参数，例如 MCID ( Multicast CID, 多播 CID)、 LCID ( Logical CID, 逻辑 CID ) 等； 本实施例中可在该请求消息中增加计费指示， 用于要求提供计费信息。
803、与 MBS Proxy位于同一网元的 MBS计费代理收集当前的 MBS业务粒度计费 信息， 例如： 该 MBS业务当前已发送的流量或时间等信息， 当前已发送的流量或时长 等信息可以为从 MBS业务开始到目前为止已经发送的 MBS流量或时间； 提供给与 MS 的 Anchor SFA位于同一网元 （ASN或者 ASN GW) 的计费客户端。 MS的计费客户端 对收到的计费信息转化为该 MS用户业务粒度的计费信息， 具体为： MS的计费客户端 将所述 MBS业务粒度计费信息加上 MS的标识， 生成该 MS用户业务粒度的计费信息， 发送给计费系统。
804、 Anchor SFA为 MS发起 MBS业务的承载建立过程， 该步骤为现有技术不在 赘述。
805、 所述新加入的 MS接收 MBS业务数据。
806、 MS的 Anchor SFA检测到终止 MBS业务的触发事件发生， 例如： AAA服务 器根据用户的签约信息通知 Anchor SFA不再为用户提供 MBS业务；或者用户主动发起
IGMP leave ( IGMP退出） 过程， Anchor DPF检测到此消息后再通知到 Anchor SFA, Anchor SFA完成授权后，为用户撤销对应的 MBS业务；或者终端发起的 DSD ( Dynamic Service Deleting, 动态服务流删除） 过程， Anchor SFA完成授权后， 为用户撤销对应的 MBS业务。
807、 MS的 Anchor SFA向 MBS Proxy发送终止 MBS业务请求消息， 用于请求终 止 MBS业务。 本发明可在该请求中增加计费指示， 用于请求 MBS业务的计费信息。
808、 与 MBS Proxy在一起的 MBS计费代理将收集到的业务粒度计费信息上报给 与 MS的 Anchor SFA在一起的 MS的计费客户端， 所述计费信息为： 该 MBS业务当前 已发送的 MBS业务流量或时间等信息， 当前已发送的流量或时间等信息可以为从 MBS 业务开始到目前为止已经发送的 MBS流量或时间。 MS 的计费客户端对收到的计费信 息进行计费处理， 具体为： MS的计费客户端对所述业务粒度计费信息加上 MS标识， 生成基于该 MS的用户业务粒度的计费信息， 发送给计费系统。
计费系统接收后， 根据 MS加入时所收到的 MS用户业务粒度计费信息， 以及 MS 退出时所收到的 MS用户业务粒度的计费信息， 两者的业务流量或时间相减， 可得到该 MS实际使用的业务流量或时间， 计费系统根据所述业务流量或时间， 便可对该 MS进 行计费。
809， 承载删除过程， 现有技术， 不再赘述。
在另一个实施例中， 步骤 803中， 并不发送给计费系统。 步骤 808中， 计费客户端 将当前得到的业务流量减去步骤 803 中得到的业务流量， 即可得到终端所使用的 MBS 业务流量数； 或者根据当前的时间减去步骤 803中得到的时间， 即可得到 MS所使用的 MBS业务时间，然后根据得到的 MS实际使用的业务流量或时间， 生成该 MS的业务粒 度计费信息上报给计费系统， 以使得计费系统进行计费。
