本发明涉及通讯领域, 尤其涉及一种计费管理方法、 系统和网元以及认证、 鉴权、 计费服务器。 发明背景
随着 3G数据业务的日益丰富, 基于内容计费的需求日益迫切。 内容计费使运营商除 收取接入费以外, 还可以对各种内容和应用进行收费, 从而获得额外的利润。 内容计费 网关(Content Charging GateWay, CCG) 是实现内容计费的一个网关网元, 主要解决 目前移动通讯网络承载的数据业务的接入、 业务控制、 计费支持等功能, CCG能支持各 种典型的数据业务如: 超文本传输协议(Hypertext Transfer Protocol , HTTP)业务、 无线应用协议(Wireless Application Protocol , WAP)浏览类业务、 网络管理子系统 (Network Management Subsystem, NMS)业务、 流媒体业务、 邮件类业务、 FTP业务等。
内容计费的功能可以在归属代理 (Home Agent, HA) 上实现, 也可以在外部代理 (Foreign Agent, FA)上实现, 以码分多址接入 ( code division multiple access , CDMA) 2000网络为例, 包括:
1、 在 FA上实现计费功能, 其中 FA的功能是在分组数据服务节点 (Packet Data Serving Node, PDSN)上实现的, PDSN也能实现内容计费网关 CCG的功能, 包括:
终端的数据流量都经过 PDSN再到数据业务网络, PDSN与在线计费系统 (Online Charging System, 0CS)通过在线计费协议 (Online Charging Protocol , OCP)接口 协议完成在线计费功能。 PDSN能够产生离线内容计费话单, 话单通过认证、 鉴权、 计费 AAA服务器传送到计费中心, 完成离线计费功能。
2、 在 HA上实现计费功能, 其中 CCG的功能也可以在 HA上实现, 包括:
终端在入网的过程中, PDSN实现终端点到点协议的终结, 终端数据通过反向隧道送 到 HA,数据流量经过 HA再到数据业务网络。 HA与 0CS通过 0CP接口协议完成在线计费功能。 HA能够产生离线内容计费话单, 话单通过认证、 授权和计费 (Authentication, Authorization and Accounting, AAA)服务器传送到计费中心, 完成离线计费功能。
如上所述,在现有 CDMA2000、宽带码分多址接入(Wideband Code Division Multiple Access , WCDMA)、 全球微波互联接入 ( Worldwide Interoperability for Microwave Access, Wimax) 等 3G网络中, 在 FA和 HA上都能实现内容计费的功能, 但是为了防止重 复计费, 对于一个移动 IP (Mobile IP, MIP)终端应选择在 FA或者在 HA上进行内容计费。

实施本发明的方式
下面将参考附图详细说明本发明实施例。
参照附图 1本发明实施例提供了一种计费管理方法, 包括:
101、接收终端发送的认证请求, 按照所述认证请求中包含的终端标识和 AAA服务器 上设置的计费网元信息, 确定所述终端的计费网元信息;
102、 将所述确定的终端的计费网元信息发送给计费网元。
应用本发明实施例所提供的方法, 在 AAA服务器上设置终端的计费网元信息, 实现 了终端选择计费网元。
在本发明实施例中,所述计费网元信息包括终端在 FA上进行计费或者在 HA上进行计 费, 所述计费网元可以是 HA、 FA, 其中在部分网络中 FA的功能可以在其他网元上实现, 如在 CDMA2000网络中 FA的功能在 PDSN上实现、 在 Wimax网络中, FA的功能在接入服务网 络网关上实现, FA的功能还可以在通用分组无线业务网关支持节点 (Gateway GPRS Supporting Node, GGSN)上实现。 终端在不同的网络架构里可以有不同的表述方式, 如在 CDMA2000网络中, 终端可以表述为移动节点, 在 Wimax里面, 终端可以表述为移动 台等等。
参照附图 2, 本发明实施例提供了一种计费管理方法, 以 CDMA2000网络为例, 其中 FA的功能在 PDSN上实现, 所述计费管理方法包括:
200、 在 AAA服务器上设置终端的计费网元信息, 包括:
在 AAA服务器上设置终端在 FA上进行计费或者在 HA上进行计费,可以基于终端的 标识, 如名称、 账号等进行设置。 例如可以设置手机号为 13502100001的终端在 HA上 进行计费, 手机号为 13502150002的终端在 FA上进行计费; 或者基于终端的账号进行 设置, 如设置帐户为 zhangsan@sohu. com 的终端在 HA 上进行计费, 账号为 wangwu@sina. com的终端在 FA上进行计费; 也可以设置某一组终端在 HA上进行计费、 另外的一组终端在 FA上进行计费等等。
步骤一、 终端建立与 PDSN之间的链路连接, 包括步骤 20广步骤 204。
201、 终端发送 All注册请求 All Registration Request消息, 请求建立与 PDSN之间 的物理层链路连接;
202、 PDSN接收到上述 All Registration Request消息后, 返回 All注册响应消息 All Registration Reply给终端, 创建 A10承载链路, 即完成和上述终端之间建立物理层的 链路连接;
203、 终端和 PDSN之间完成链路控制协议(Link Control Protocol , LCP)协商, 完成对终端的认证方式的协商;
204、 终端与 PDSN之间的完成 LCP协商后进行网络层协议 (IP Control Protocol , IPCP) 协商, 包括:
a、 终端发送 IP地址分配请求消息 IPCP Configure Request给 PDSN, 该消息中可以 包括终端的 IP地址, 也可以不包括终端的 IP地址, 如果不包括终端的 IP地址则所述终端 为移动 IP MIP终端, 如果包括终端的 IP地址, 则所述终端为简单 IP终端。
所谓的 MIP是一种在 IP网络上提供移动功能的方案, 它使终端在切换链路时仍能保 持现有的通信, 并使用一个永久 IP 地址连接到任何链路上; 简单 IP只能支持终端主动 发起的分组数据业务, 当 PDSN发生了切换时, 则会中断现有的数据业务并需重新分配或 协商 IP地址;
b、 PDSN回 IP地址分配响应 IPCP Configure Reply消息给终端, 完成 IPCP协商, 终 端和 PDSN之间完成 LCP协商和 IPCP协商后, 即完成 PPP协商, PPP链路建立完成;
步骤二、 终端接收到代理广播消息后向 PDSN发送 MIP注册请求, 包括步骤 205〜步骤
208。
205、 PDSN和终端建立起 PPP链路后, 如果 PDSN判断该终端是 MIP终端, 则向终端发 送 MIP代理广播消息, 所述代理广播消息包含代理转交地址(Care-of-Address, CoA) ; 如果该终端是简单 IP终端, 则由 PDSN分配 IP地址, 直接与其要访问的业务的服务器建立 连接, 访问所述业务。
206、 可选地, 终端在收到代理广播消息之前, 也可能向 PDSN发送了 MIP代理请求 消息 MIP Agent Solicitation;
207、 可选地, PDSN 收到代理请求消息后, 向终端回复 MIP 代理广播 MIP Agent Advert isment消息, 同样也包含有代理转交地址 CoA;
208、 终端收到代理广播消息后, 并根据该代理广播消息所包含的代理转交地址, 向 PDSN发送 MIP注册请求 MIP RRQ消息;
步骤三、 PDSN向 AAA服务器发送认证请求, AAA服务器根据认证请求中的终端标识 和在 AAA服务器上设置的计费网元信息, 确定所述终端的计费网元; AAA服务器返回的 认证响应到 PDSN, 所述认证响应中包含所述终端的计费网元信息, 包括步骤 209〜步骤 2010。
209、 PDSN接收到 MIP RRQ消息后, 根据 MIP RRQ消息中包含的认证信息发送认证 请求 Access Request消息到 AAA服务器, 所述认证信息可以包括认证方式、 终端的标 识、终端所对应的 AAA服务器的地址等, 所述认证请求中包含终端的标识, 所述 Access Request消息可以封装成 RADIUS的报文到 AAA服务器进行认证,也可以封装成 Diameter 报文到 AAA服务器进行认证;
2010、 AAA服务器根据认证请求中的终端标识和在 AAA服务器上设置的计费网元信 息, 确定所述终端的计费网元信息; 并返回认证响应 Access-Accept消息给 PDSN, 所述 Access-Accept消息包含终端的计费网元信息, 标识该终端是在 PDSN还是 HA上进行计 费;
AAA服务器接收到封装成 RADIUS的 Access Request消息后, 解析出该消息中包含 的终端标识, 如该终端的帐号为 wangwei@huawi. com, 根据在 AAA服务器上的设置, 可 知该终端在 HA上进行计费, 则返回认证结果, 包含的计费网元信息为该终端在 HA上进 行计费, 可以将认证响应 Access-Accept消息封装成 RADIUS报文发送给 PDSN, 也可以 将 Access-Accept消息封装成 Diameter报文发送给 PDSN。
步骤四、 PDSN发起注册请求到 HA进行 MIP注册, 包括步骤 2011。
2011、 PDSN接收到认证响应消息后,发送 MIP注册请求消息 MIP RRQ到 HA进行 MIP 注册;
步骤五、 HA发送认证请求到 AAA服务器, AAA服务器根据认证请求中包含的终端标 识和在 AAA服务器上设置的计费网元信息, 确定所述终端的计费网元, AAA服务器返回 认证响应到 HA, 所述认证响应中包含所述终端的计费网元信息, 包括步骤 2012〜步骤 2013。
2012、 HA接收到 MIP注册请求消息后,发送认证请求到 AAA服务器进行认证, 所述 注册请求消息中包含终端的标识和终端所对应的 AAA服务器的地址等,所述认证请求中 包含终端的标识; 可以将认证请求 Access Request消息封装成 RADIUS报文发送给 AAA 服务器, 也可以将 Access Request消息封装成 Diameter报文发送给 AAA服务器;
2013、 AAA服务器收到认证请求消息后, 对终端进行鉴权、 授权, 根据所述认证请 求中包含的终端标识和在 AAA服务器上设置的计费网元信息,确定所述终端的计费网元; AAA服务器完成对终端的授权后返回认证响应消息给 HA,将认证响应消息 Access Accept 封装成 RADIUS报文发送给 HA, 所述认证响应消息包含终端的计费网元信息;
AAA服务器根据接收到的认证请求消息中包含的终端标识与在 AAA服务器上的设置 的计费网元信息进行对比, 确定该终端是在 HA上还是在 PDSN上进行计费, 如果在 AAA服 务器上设置手机号为 15002100002的终端在 PDSN上进行计费, 而该终端的手机号码为 15002100002, AAA服务器确定所述终端在 PDSN上进行计费, 将所述终端在 PDSN上计费的 计费网元信息发送给 HA, 也可以将 Access-Accept消息封装成 Diameter报文发送给 HA; 步骤六、 HA发送 MIP注册成功响应给 PDSN, 如果终端的计费网元信息中包含所述终 端在 HA上进行计费, 则 HA开始对终端进行计费, 包括步骤 2014, 其中步骤 2014a和 2014b 可以不分先后顺序。
2014a、 HA收到认证响应消息后, 发送 MIP注册成功 MIP RRP的消息给 PDSN;
2014b, HA收到认证响应消息后, 根据所述消息中包含的计费网元信息, 此步骤中 因为所述终端的计费网元在 HA上, 则 HA对终端进行计费, 如果所述终端的计费网元在 FA上, 则不对终端进行计费;
步骤七、 PDSN发送 MIP注册成功消息给所述终端,如果所述终端的计费网元信息中 包含所述终端在 PDSN上进行计费, 则 PDSN开始对终端进行计费, 包括步骤 2015, 其中 步骤 2015a和 2015b可以不分先后顺序。 2015a, PDSN收到 MIP RRP消息后, 发送 MIP注册成功消息 MIP RRP给终端;
2015b, PDSN收到 MIP RRP消息后, 根据该消息中包含的计费网元信息, 如果所述 终端的计费网元是 HA,则不对所述终端进行计费,此步骤中因为所述终端的计费网元是 PDSN, 则 PDSN对所述终端进行计费。
在本发明实施例所提供的方法中, 终端的计费网元信息设置在 AAA服务器上, 当终 端进行鉴权认证时, AAA服务器将终端的计费网元信息发送 HA和 PDSN, HA和 PDSN按照 所述计费网元信息确定是否对所述终端进行计费, 实现了基于终端选择计费网元, 进一 步也能实现对终端的灵活计费。
本发明实施例中,在终端入网鉴权阶段可以将认证鉴权请求消息和认证鉴权响应消 息封装成 RADUS报文或者 Diameter报文发送给 AAA服务器, AAA服务器返回的认证响应消 息也可以封装成 RADUS报文或者 Diameter报文, 所述认证响应消息中包含有终端的计费 网元信息。 RADIUS和 Diameter协议参数的 AVP数据格式是相同的, 因此 RADIUS或者 Diameter报文中包含一个名称为 Charging-Point的 AVP, 如表 1所示:
Figure imgf000008_0001
表 1
其中, 该 AVP表示 RADIUS或者 Diameter协议中的一个属性, AVP的名称是 Charge-Point, 表示这是一个计费网元信息, AVP码为 20516, AVP类型为 Unsigned32, 该计费网元中包含有 "0"和 " 1 "两个标识, 其中 "0 "表示在 PDSN上进行计费, " 1 " 表示在 HA上进行计费, 其他参数为无效值。 表 1中只是一种具体的设置方式, 在符合规 则的情况下, 也可以有其他的设置。
在本发明实施例中, AM服务器如果确定该终端是在 HA上进行计费, 可以只将终端 的计费网元信息发送给 HA, HA接收到终端的计费网元信息后, 开始对该终端进行计费, PDSN没有收到该终端的计费网元信息, 默认对该终端不进行计费, 其实现流程和本发明 实施例类似, 区别点在于: 在步骤 2010中, AAA服务器返回的认证响应消息中不包括终 端的计费网元信息, 步骤 2015b中, PDSN默认不对终端进行计费。
同理 AAA服务器如果确定该终端是在 FA上进行计费, 可以只将终端的计费网元信息 发送给 PDSN, PDSN接收到终端的计费网元信息后, 开始对该终端进行计费, HA没有收到 该终端的计费网元信息, 默认对该终端不进行计费, 其实现流程和本发明实施例类似, 区别点在于: 在步骤 2013中, AAA服务器返回的认证响应消息中不包含终端的计费网元 信息, 步骤 2014b中, HA默认不对终端进行计费。 在本发明实施例中, 如果终端处于漫游状态下, 当终端入网时, 存在拜访认证、 鉴 权、 计费 VAAA服务器和家乡认证、 鉴权、 计费 HAAA服务器, 其实现流程和本发明实施例 类似, 区别点在于:
终端的认证请求通过 VAAA服务器发送给 HAAA服务器, HAAA服务器按照认证请求中终 端的标识和在 HAAA服务器上设置的计费网元信息, 确定所述终端的计费网元信息, 将所 述终端的计费网元信息通过 VAAA服务器发送给计费网元。
应用本发明实施例所提供的方法, 当终端发生漫游时, 计费网元也能获取终端的计 费网元, 实现对终端的准确计费。 在 Wimax网络中, FA的功能在为 ASN-GW上实现的, 简称 ASN, 如果终端正在访问业务 的过程中 ASN发生了切换, 切换后的 ASN不能获取该终端的计费网元信息, 会造成计费不 准确。
参照附图 3, 本发明实施例提供了一种计费管理方法, 当 ASN发生了切换时, 包括: 终端发生网关 GW切换, 如果导致 ASN也发生了切换, 切换到目标 ASN后, 目标 ASN根 据终端的标识查找到对应的终端切换前的源 ASN, 目标 ASN向源 ASN发起切换触发消息, 其中所述目标 ASN是发生切换后的 ASN, 源 ASN是发生切换前的 ASN, 源 ASN上保存有 AAA服 务器发送的终端计费网元信息;
301、 目标 ASN向源 ASN发送切换触发 Anchor DPF HO Trigger消息, 触发源 ASN切换;
302、 源 ASN发送切换请求 Anchor DPF HO Req消息到目标 ASN, 所述切换请求消息中 包含该终端的计费网元信息, 标识该终端是在 ASN上还是在 HA上进行内容计费;
303、 目标 ASN接收到源 ASN发送的切换请求消息后, 目标 ASN向终端发送 MIP Advertisements代理广播消息, 消息中包含目标 ASN的代理转交地址 CoA;
304、 终端收到目标 ASN的代理转交地址后发起 MIP注册请求 MIP RRQ消息给目标 ASN, 请求进行 MIP注册;
305、 目标 ASN收到 MIP注册请求消息后, 把 MIP注册请求消息发送给 HA;
306、 HA接收 MIP注册请求消息, 对上述终端进行注册, 注册成功后, HA回应 MIP注 册响应 MIP RRP消息, 指示 MIP注册成功;
307、 目标 ASN接收到 HA返回的 MIP注册响应消息后, 获知所述终端在 HA上注册成功, 目标 ASN将 MIP注册响应消息转发给终端, 指示 MIP注册成功;
308、 目标 ASN返回源 ASN切换成功响应 Anchor DPF HO Rsp消息, 表示目标 ASN取代 源 ASN成为所述终端的外部代理。
步骤 307和步骤 308也可以不分先后顺序, 同时进行。
目标 ASN取代源 ASN成为所述终端的外部代理后, 目标 ASN根据源 ASN发送的切换请求 中包含的计费网元信息确定对所述终端是否进行计费, 如果该终端的计费网元为 ASN, 则目标 ASN对终端进行计费, 如果该终端的计费网元为 HA, 则目标 ASN不对该终端进行计 费。 在 ASN切换过程中, 源 ASN向目标 ASN发送的切换请求 Anchor DPF HO Req消息中包含 Charging Point参数, 所述 Charging Point参数表示终端的计费网元信息, 参数的值为 一个字节, 定义如表 2所示:
Figure imgf000010_0001
表 2
表中参数的名称是 chargeing Point, 表示的是终端的计费网元信息; 参数中标识 "0"表示在 ASN上计费, 标识 " 1 "表示在 HA上计费, 其他符号均表示无效值。
在本发明实施例中, 目标 ASN从源 ASN中获取终端的计费网元信息, 按照所述计费 网元信息中所确定的计费网元, 确定 ASN是否对所述终端进行计费, 在终端访问业务的 过程中发生 FA切换时, 保证了计费的准确性和连贯性。
当 ASN发生切换时,目标 ASN也能从 AAA服务器中获取终端的计费网元信息,包括: 目标 ASN与 HA建立连接之前, 目标 ASN重新到 AAA服务器进行认证, 目标 ASN发送认 证请求到 AAA服务器, AAA服务器返回的认证结果中包含所述终端的计费网元信息。
当 ASN发生切换时, 目标 ASN也能从 HA上获取终端的计费网元信息, 包括: 在步 骤 306中, HA返回 MIP注册响应 MIP RRP消息给 ASN, 指示 MIP注册成功, MIP RRP消 息中包含所述终端的计费网元信息, 指示该终端是在 ASN上还是在 HA上进行计费。
其中, HA返回的 MIP注册响应 MIP RRP消息中包含 Charging Point参数, 所述参 数表示计费网元信息,字长为 lbyte,参数中标识" 0"表示在 FA上进行计费,标识" 1 " 表示在 HA上进行计费, 其他值表示无效值, 如表 3所示:
Figure imgf000010_0002
