一种触发计费的方法、 接入网和通信系统 技术领域
本发明涉及通信技术, 尤其涉及一种触发计费的方法、 接入网和通信系统。 背景技术
WiMAX(Worldwide Interoperability for Microwave Access), 中文全称是全球接入微波互 操作性, 是一种基于 IEEE 802.16标准的无线城域网技术。 WiMAX网络主要由三个部分组 成即终端 (MS/SS: Mobile Station/Subscriber Station ) 接入业务网 (ASN: Access Service Network) 包括基站 (BS: Base Station ) 和接入业务网网关 (ASN GW: Access Service Network-GateWay) 和连接业务网 (CSN: Connectivity Service Network) 包括预付费服务器 (PPS: Prepay Server) 认证、 授权和计费服务器 (AAA Server: Authentication Authorization Accounting Server)等逻辑实体。如图 1中所示, WiMAX整个网络主要由如下三部分组成: (1) 终端 (SS/MS): 用户使用该设备接入 WiMA 网络。
(2)接入业务网 (ASN): ASN定义为终端提供无线接入服务的网络功能集合。 ASN包含 了 BS和 ASN-GW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): CSN定义为终端提供 IP连接服务。 CSN所提供的主要功能为: 终端 MS的 IP地址分配、 Internet接入、 AAA proxy或者 server、 基于用户的授权控制等。
上述各逻辑实体间通过从 R1到 R6的接口来进行通信,各网元及接口关系如图 1所示。 ASN的作用主要包括以下几个方面: 确保 WiMA 终端与 WiMAX基站之间二层连接 的建立; 无线资源管理; 网络发现以及 WiMAX用户网络业务供应商的最优选择; 在代理 移动 IP模式下,充当代理服务器控制 WiMAX用户的认证、授权以及计费消息; 为 WiMAX 终端三层应用连接的建立提供中继。
CSN的作用主要包括以下几个方面: 为 WiMAX用户会话分配 IP地址; 提供互联网接 入; 充当认证授权计费代理服务器或者认证授权计费服务器; 基于用户签约数据进行策略 和访问控制; 支持 ASN与 CSN之间隧道的建立; 支持 WiMA 用户话单的生成以及跨运 营商之间的 WiMAX业务结算; 支持 CSN之间漫游隧道的建立; 支持 ASN之间的移动性; 支持多种 WiMAX业务, 例如基于位置的业务、 端到端业务、 多媒体广播与多播业务等等。 现有技术中的计费模型是针对一个用户有不同粒度的计费层次: 一个用户 (subscriber) 可以根据不同的网络接入指示(NAI: Network Access Identifier)有多个签约 (subscription); 一个签约对应到一个设备会话 (device-session); 每一个设备会话可以根据 IP地址对应到一 个或多个计费粒度 IP会话 (IP Session); 每一个计费粒度 IP会话又可以根据 PDF ID对应到一 个或多个计费粒度分组数据流 (PD-flow)。 计费信息采集是在 IP会话 (IP Session) 和分组 数据流(PD-flow)这两个粒度模型上的。 每一个设备会话还可以根据 MAC地址对应到一个 计费粒度 MAC会话(MAC Session); 每一个计费粒度 MAC会话又可以根据 PDF ID对应到一 个或多个计费粒度分组数据流(PD-flow),这里的 PD-flow是面向以太网汇聚子层 Ethernet-CS 业务的数据流。 计费信息采集是在 MAC会话 (MAC Session) 和分组数据流 (PD-flow) 这 两个粒度模型上的。

方式 1、所述融合实体 IWF可以通过解析所述终端的 PPP数据来判断所述 DSL网络对 所述终端的鉴权是否成功, 所述融合实体 IWF解析 PPP数据, 若检测其中包含鉴权成功或 PPP建立成功的信息则判断判断鉴权成功, 若检测其中包含强制释放 PPP通道的指示则判 断鉴权失败;
方式 2、 所述融合实体 IWF可以通过监视承载 PPP的通道, 如监视 PPPoE或 L2TP的 信令来判断所述 DSL网络对所述终端的鉴权是否成功,如果 PPP鉴权失败,则 DSL网络中 的 BRAS或 LNS会主动发起 PPPoE或 L2TP隧道 /会话的释放流程,若没有触发释放流程而 直接出现后继的数据传输, 则可认为是鉴权成功;
方式 3、 所述融合实体 IWF可以通过检测所述终端和所述 DSL网络是否有数据交互来 判断所述 DSL网络对所述终端的鉴权是否成功。

这里, 可以是终端发起退出 DSL网络, 也可以是由 WiMAX网络发起退出 DSL网络, 或由 DSL网络发起终端退出 DSL网络。 终端通过所述融合实体 IWF同所述 DSL网络交互 退出所述 DSL网络。
步骤 606-607、 所述融合实体 IWF检测到终端退出 DSL网络, 触发计费客户端终止对 终端进行基于以太网汇聚子层 Ethemet-CS的计费。
本发明实施例中,所述融合实体 IWF检测到终端退出 DSL网络具体可以为以下几种方 式:
方式 1、 所述融合实体 IWF可以通过解析所述终端的 PPP数据来判断所述终端是否退 出 DSL网络,如若解析到所述 PPP数据中包含有 PPP释放的相关信令则判断终端退出 DSL 网络;
方式 2、 所述融合实体 IWF可以通过监视承载 PPP的通道, 如 PPPoE或 L2TP的信令 来判断所述终端是否退出 DSL网络, 如可以通过检测 PPPoE或 L2TP等承载 PPP信令的承 载通道的释放来确定其所承载的 PPP的释放, 从而判断所述终端是否退出 DSL网络; 方式 3、 所述融合实体 IWF可以通过检测所述终端和所述 DSL网络是否正常通信来判 断所述终端是否退出 DSL网络。

步骤 703〜步骤 706、 IWF获知所述终端在 WiMA 入网完成后 (例如 IWF可以位于 Anchor DPF或 HA, 可凭借已有 WIMAX流程获知所述终端 WiMAX入网成功), 代替终端 建立 PPP连接到 DSL网络中,本发明实施例以 A10接口融合场景为例, IWF建立 L2TP 隧 道 /会话到 LNS ; 如果是 V接口融合场景, 则 IWF建立 PPPoE会话到 BRAS。 IWF代替终 端完成 DSL网络的鉴权以及参数的协商配置操作,包括获取 DSL网络为所述终端分配的 IP 地址。
步骤 707、 IWF检测到所述终端在 DSL鉴权成功, 触发计费客户端对终端进行基于以 太网汇聚子层 Ethernet-CS的计费。

进一步的, 若终端退出 WiMAX网络, 则触发终止计费。 如图 7所示, 具体如下: 步骤 709、 所述终端退出 WiMAX网络, 释放终端到所述数据面实体之间的传输通道, 如果所述融合实体 IWF与所述数据面实体位于不同的物理实体, 则可以进一步的通过歩骤 709a和 709b分别释放终端到数据面实体、 以及数据面实体到 IWF间的传输通道。
步骤 710、 IWF获知所述终端在 WiMAX退网, 触发 IWF释放所述终端与 DSL网络的
PPP连接, 包括释放 PPP连接以及所述 PPP连接使用的承载, 若为 A10接口融合的场景, 则此承载为 L2TP隧道或会话, 若为 V接口融合场景, 则此承载为 PPPoE会话。
