Description

支持非 3GPP接入的演进分组核心网计费方法及*** 技术领域
本发明涉及计费技术， 尤其涉及一种支持非第三代合作伙伴计划 ( 3GPP, 3rd Generation Partnership Project )接入的演进分组核心网计费方 法及***。 背景技术
长期演进（LTE， Long Term Evolution )预期不久以后将主要通过固定 技术迎合宽带市场的需求， 为适应无线侧的速度增长， 对核心网构架进行 进一步的演进就成为 3GPP组织研究的一个重点课题，这也是***构架演进 ( SAE, System Architecture Evolution )项目的重要内容， 也称为演进的分 组核心网（ EPC， Evolved Packet Core )即 EPC。演进分组***（ EPS， Evolved Packet System )是未来移动网络演进的方向， 主要特征包括： 全面分组化， 提供真正意义上的纯分组接入； 支持多接入技术， 除支持现有 3GPP***接 入外， 同时支持非 3GPP网络（如码分多址（ CDMA， Code Division Multiple Access ), 无线局或网络 ( WLAN, Wireless Local Area Network ) ) 的接入， 并支持在 3GPP网络和非 3GPP网络之间的漫游和切换；支持端到端的服务 质量（QoS， Quality of Service )保证， 增加了对实时业务的支持， 通过简 化网络架构和信令流程， 降低业务连接的时延； 网络层次扁平化， 在用户 面进行节点压缩，取消了无线网络控制器（ RNC, Radio Network Controller )， 核心网用户面节点在非漫游时可合并为一个。
EPC网络实现了核心网的融合， 支持各种 3GPP接入方式和 non-3GPP 网络的共接入， 并支持多模终端用户的无缝移动性。 运营商全业务运营的 发展趋势， 使得运营商开始面对运营多种制式网络。 支持多种网络共接入 的 EPC网络， 实现核心网的融合， 使得网络结构更加简单， 降低了网络运 营成本。 同时 EPC网络支持各种接入方式之间的无缝移动性， 提高了 LTE 用户在 LTE部署初期局部覆盖时的使用感受。
由于 EPC***同时支持 3GPP接入（如 LTE )、 信任的非 3GPP网络接 入（如 CDMA )和非信任非 3GPP IP网络接入（如 WLAN等）， 3GPP也定 义了支持非 3GPP接入的 EPC架构图， 其中分组数据网（ PDN， Packet Data Network ) 网关（GW， Gateway )作为接入的核心设备， 不同接入网络的接 入网关（ LTE无线网对应 S-GW， CDMA无线网对应 HSGW， WLAN无线 网对应 ePDG )分别接入 P-GW ( PDN GW ) 实现异质网络的接入。 归属用 户服务器（ HSS， Home Subscriber Server )作为 EPC网络鉴权认证的核心， 除支持 LTE网络认证外，对于 CDMA和 WLAN的网络认证，则先通过 3GPP AAA服务器统一处理后， 也在 HSS实现最终的接入认证和鉴权。
图 1为支持非 3GPP接入方式的 EPC漫游架构 a的示意图， 图 2为支 持非 3GPP接入方式的 EPC漫游架构 b的示意图， 图 3为支持非 3GPP接 入方式的 EPC漫游架构 c的示意图，图 1、图 2和图 3分别表示支持非 3GPP 网络接入 EPC的三种可能漫游架构 （P-GW位于家乡网络的 Home-Routed 的漫游情况）。 三者的区别在于， 图 1使用 P-GW作为非 3GPP接入的锚定 点及 S8、 S2a和 S2b接口， 信任的非 3GPP (如 CDMA等）接入通过 3GPP AAA进行接入认证和鉴权；非信任的非 3GPP(如 WLAN等展入通过 3GPP AAA进行接入认证和鉴权， 用户面信息经由 ePDG接入 P-GW。 图 2使用 S-GW作为非 3GPP接入的锚定点及 S8、 S2a-PMIP和 S2b接口； 图 3使用 S8和 UE与 P-GW之间的 S2c接口。 P-GW产生计费标识（ Charging ID ) 用于从计费角度指示同一个 IP-CAN承载， ePDG可以通过 GTP ( GPRS Tunnel Protocol ) 隧道直接获知或者以代理移动互联网协议（PMIP， Proxy Mobile Internet Protocol ) 方式通过策略控制和计费 （PCC， Policy and Charging Control )架构间接获知这一信息。 ePDG产生 PDN链接标识 PDN Connection ID用于指示同一个 IP-CAN会话； P-GW也可以通过 GTP隧道 直接获知或者以 PMIP方式通过 PCC架构间接获知这一信息。
目前对于以上描述的图 1、图 2及图 3这种支持非 3GPP网络接入 EPC 的增强架构， 已知 P-GW通过特定的计费接口会产生计费信息， 但是对于 访问网络和归属网络属于不同运营商的情况，当 P-GW位于归属网络， ePDG 位于访问网络时， 仅依靠 P-GW的计费是无法完成不同运营商网络的清分 和对账的。 发明内容

图 11为本发明在线计费机制下的计费流程图。 具体实施方式 本发明的基本思想是：计费逻辑功能实体 CTF接收到 EPC中用于负责 非 3GPP接入网络接入的网元发送的、通过非 3GPP接入网络接入网的演进 分组数据用量后， 产生计费信息并发送给离线计费网关和 /或在线计费*** 用于计费； 计费***基于所述演进分组数据的计费信息进行计费。
上述 CTF， 具体设置于 ePDG中， 和 /或设置于所述 ePDG之外。 上述 CTF设置于所述 ePDG之外， 为： CTF设置于 3GPP AAA中或其他网元中。
上述离线计费网关中设置有 CDF和 CGF。 上述 CDF和 CGF可设置于 ePDG中； CDF和 CGF设置于 ePDG中时， ePDG和离线计费网关合设。
或者， CDF设置于所述 ePDG中， CGF设置于所述 ePDG之外； 或者， CDF和 CGF设置于 3GPP AAA中； CDF和 CGF设置于 3GPP AAA 中时， 3GPP AAA和离线计费网关合设。
或者， CDF设置于 3GPPAAA中， CGF设置于所述 3GPP AAA之夕卜。
CTF设置于 3GPP AAA中时， 3GPP AAA从 ePDG和 /或 HSGW获取 非 3GPP接入网的演进分组数据用量。
CTF设置于其他网元中时， 所述 3GPP AAA从所述其他网元获取所述 非 3GPP接入网的计费相关的信息。
以下结合附图，对本发明的支持非 3GPP接入的演进分组核心网计费系 统作进一步详细阐述。
具体的，本发明的支持非 3GPP接入的演进分组核心网计费***包括用 户设备、信任的和 /或非信任的非 3GPP接入网络、 EPC核心网网元、 ePDG、 用于生成演进分组数据计费信息的计费逻辑功能实体、 以及、 离线和 /或在 线计费***； 其中， EPC核心网网元包括 S-GW、 P-GW、 HSS、 策略控制 和计费 PCC相关网元等；演进分组数据网关和计费信息的逻辑实体及离线 / 在线计费***相连。
其中， 演进分组数据计费逻辑功能实体为 CTF、 CDF和 CGF的一种或 多种组合， 可以内嵌于 ePDG或 3GPPAAA, 也可以部分或全部独立部署。
图 4为本发明支持非 3GPP接入方式的离线计费结构示意图， 如图 4 所示， 计费方式为离线计费时， CTF、 CDF和 CGF可以都内嵌于 ePDG， 此时， ePDG通过 Bsw接口发送 CDR文件到离线计费*** Billing Domain; 当 CGF独立于 ePDG部署时， CTF、 CDF内嵌于 ePDG中， ePDG通过 SWz 接口发送用户的计费信息到 CGF， CGF在采集这些计费信息进行后续处理 后封装为 CDR文件， 通过 Bsw接口发送到离线计费*** Billing Domain。 当 CDF独立于 ePDG部署时， 而 CTF内嵌于 ePDG， ePDG产生 SWf接口 发送计费请求消息 ACR到 CDF。图 4中说明了本发明中可能的计费逻辑功 能实体的可能部署方式， 实际***中选取一种部署方式即可。 对于其他可 能的计费信息的逻辑实体的部署方式， 不再一一列举。
需要说明的是，上述的计费逻辑功能实体也可以设置于 3GPPAAA中， 部署方式与设置于 ePDG中时的部署方式基本相同， 这里不再赘述。 如图 4 所示， 信任的和 /或非信任的非 3GPP接入网发送计费相关的信息给 3GPP AAA，然后 3GPP AAA发送计费数据给离线计费***。在这种方式中， 3GPP AAA可以接收来自信任的和 /或非信任的非 3GPP接入网的计费相关的信 息， 在下文的实施例中用 HSGW和 ePDG来分别表示信任的和非信任的非 3GPP接入网接入 3GPPAAA的网关， 实际上信任的和 /或非信任的非 3GPP 接入网有多种可能的网关， 不局限于此。 如： 某些固网接入的情况或者有 些 WLAN接入被认为是非信任的非 3GPP接入，而有些 WLAN接入则被认 为是信任的非 3GPP接入（比如***的 WLAN接入***的网络）。
实际上， 不论计费逻辑功能实体以何种部署方式进行部署， 其与 ePDG 或 3GPP AAA交互的方式基本是确定的， 即对于离线计费结构， ePDG或 3GPP AAA (内设置有 CTF ) 向 CDF发送 ACR消息， ACR消息中携带有 用户的演进分组数据用量； CDF接收到 ACR消息后， 向 CGF发送计费数 据请求 CDR消息， CDR消息中携带有用户的演进分组数据用量； CGF基 于用户的演进分组数据用量生成 CDR文件， 并发送给离线计费***； 离线 计费***基于 CDR文件进行计费。
图 5为本发明支持非 3GPP接入方式的在线计费结构示意图， 如图 5 所示， 计费方式为在线计费时， CTF内嵌于 ePDG， ePDG通过 SWy接口 与在线计费***（OCS， Online Charging System ) 交互信用控制请求 /信用 控制响应消息进行实时在线计费。 也可以由信任的和 /或非信任的非 3GPP 接入网发送计费相关的信息给 3GPP AAA, 然后由 3GPP AAA发送在线计 费数据给在线计费***。 如： 通过 HSGW/ePDG (信任的和 /或非信任 3GPP 网络通过 HSGW/ePDG接入）将计费相关信息传递到 3GPPAAA, 由 3GPP AAA(内设置有 CTF )通过 SWo接口与在线计费***（OCS，Online Charging System ) 交互信用控制请求 /信用控制响应消息进行实时在线计费。
本发明中， 根据不同的漫游架构的特点及运营商部署的需要， ePDG可 以和 P-GW统一部署，如图 1所示的架构中， ePDG即可以与 P-GW统一部 署， 本发明中， 所谓统一部署即是 ePDG与 P-GW—体设置。 图 6为本发 明 ePDG与 P-GW统一部署的计费接口示意图，如图 6所示， P-GW功能子 设备通过离线计费接口 Ga/SWz与离线计费网关 CGF连接， 通过在线计费 接口 Gy/SWy与在线计费***连接。 在这样的离线计费接口和在线计费接 口上， 原本 ePDG单独部署产生的计费信息要进行到 P-GW产生的计费信 息的映射， 生成统一的由 P-GW产生的新的计费信息。
本发明中， 根据不同的漫游架构的特点及运营商部署的需要， ePDG可 以和 S-GW统一部署，如图 2所示的架构中， ePDG即可以与 S-GW统一部 署， 本发明中， 所谓统一部署即是 ePDG与 S-GW—体设置。 图 7为本发 明 ePDG与 S-GW统一部署的计费接口示意图，如图 7所示， S-GW功能子 设备通过离线计费接口 Ga/SWz与离线计费网关 CGF连接； 原本 ePDG单 独部署产生的计费信息要进行到 S-GW产生的计费信息的映射， 生成统一 的由 S-GW产生的新的计费信息。 同时统一部署的 S-GW依然通过 S5/S8 接口和 P-GW相连。
以下， 结合本发明的支持非 3GPP接入的演进分组核心网计费***，对 本发明的支持非 3GPP接入的演进分组核心网计费方法作详细阐述。

步骤 802: ePDG发送携带用户当前数据流量、计费标识（ Charging ID ) 和 PDN Connection ID等计费相关信息发送给离线计费网关； 本步骤中， 根 据计费逻辑功能实体的不同部署情况， ePDG可以发送 ACR ( CDF独立于 ePDG部署）消息到 CDF， 也可以发送 CDR ( CDF和 CTF都内嵌于 ePDG ) 消息到 CGF， 也可以发送 CDR文件到 Billing Domain ( CTF、 CDF和 CGF 都内嵌于 ePDG ); 具体方式可参见前文的相关描述。 接口离线计费网关采 集计费信息生成 CDR文件，离线计费*** Billing Domain根据 CDR文件产 生账单。
步骤 803:离线计费网关响应计费数据请求返回计费数据响应到 ePDG。 图 9为本发明在线计费机制下的计费流程图， 如图 9所示， 本示例在 线计费机制下的计费方法包括以下步骤：
步骤 901: 经 3GPPAAA的接入认证和鉴权， 非信任的非 3GPP接入网 如 WLAN被允许接入 EPC核心网；

步骤 903: OCS返回信用控制响应到 ePDG， 信用控制响应中携带保证 的业务单元 GSU;
步骤 904: 当在线计费和离线计费都被支持的情况下， 计费域（ Billing Domain )接收 ePDG发送来的计费数据， 进一步生成账单。
图 10为本发明离线计费机制下的计费流程图， 如图 10所示， 本示例 离线计费机制下的计费方法包括以下步骤：
步骤 1001: 经 3GPP AAA的接入认证和鉴权， 信任的非 3GPP接入网 如 CDMA和 /或非信任的非 3GPP接入网如 WLAN等均被允许接入 EPC核 心网， 其中 HSGW (家乡服务网关）是一种信任的非 3GPP接入网关； 步骤 1002: 信任的非 3GPP接入网关和 /或非信任的非 3GPP接入网关 如 HSGW/ePDG 上报当前用户流量信息到 3GPP AAA , 携带计费标识 ( Charging ID )和 PDN Connection ID等相关计费信息。
步骤 1003: 3GPP AAA发送含有当前用户流量信息、计费标识（ Charging ID )和 PDN Connection ID等相关计费信息到离线计费网关 /离线计费***； 其中计费逻辑功能实体在 3GPP AAA的部署也如同实施例一的情况存在多 种可能， 这里不再——赘述。
步骤 1004:离线计费网关响应计费数据请求返回计费数据响应到 3GPP AAA。
图 11为本发明在线计费机制下的计费流程图， 如图 11所示， 本示例 在线计费机制下的计费方法包括以下步骤：
步骤 1101: 经 3GPP AAA的接入认证和鉴权， 信任的非 3GPP接入网 如 CDMA和 /或非信任的非 3GPP接入网如 WLAN等均被允许接入 EPC核 心网， 其中 HSGW是一种信任的非 3GPP接入网关；

步骤 1103: 内嵌 CTF的 3GPP AAA发送携带用户当前数据流量的信用 控制信息给在线计费*** OCS， OCS根据计费策略和当前数据流量的份额 请求及对应的业务类型做相应的信用控制。 步骤 1104: OCS返回信用控制响应到 3GPP AAA， 其中信用控制响应 中携带有保证的业务单元 GSU;
步骤 1105: 当在线计费和离线计费都被支持的情况下， 计费域接收 3GPPAAA发送来的计费数据， 进一步生成账单。
本发明中， 当根据支持非 3GPP接入 EPC的不同的漫游架构及运营商 的部署需求， 决定统一部署 P-GW和 ePDG时， 原本由 ePDG与离线 /在线 计费接口连接， 此时由 P-GW与离线 /在线计费接口连接， 如图 8所示， 此 时 P-GW上的离线 /在线计费接口将在该 P-GW的接口上映射属于 ePDG的 计费接口的内容。
当根据支持非 3GPP接入 EPC的不同的漫游架构及运营商的部署需求， 决定统一部署 S-GW和 ePDG时， 原本由 ePDG与离线计费接口连接， 此 时由 S-GW与离线计费接口连接， 如图 9所示， 此时 S-GW上的离线计费 接口将在该 S-GW的接口上映射的属于 ePDG的计费接口的内容。而 P-GW 与 OCS之间通过 S-GW和 P-GW之间的 S5/S8接口进行在线计费信息的交 互交。
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。
