但是目前这些功能实体只根据用户终端的接入位置信息进行业务处理,当 用户终端从非 3GPP接入网络接入 3GPP核心网时, 这些功能实体并不感知用户 当前所在 3GPP接入网络的位置, 使得在进行业务处理的过程中, 业务处理不 精确。 发明内容

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。基于本发明中的实施例, 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
方法实施例一
一种业务处理方法, 本发明实施例的方法适用于当用户终端通过非 3GPP 接入网络接入 3GPP核心网的过程中, 由网络中的一些功能实体执行的方法, 可以为计费话单生成方法, 也可以为合法监听方法, 还可以为策略控制、 策略 下发等业务处理的方法, 流程图如图 1所示, 包括:
步骤 101、 获取用户终端当前所在第三代伙伴计划 (以下简称 3GPP ) 网 络小区的小区标识;
当用户终端从非 3GPP接入网络接入 3GPP核心网的过程中, 由非 3GPP 接入网络,或 ANDSF获得用户终端当前所在 3GPP网络小区的小区标识( cell ID )如小区位置号、 小区地址信息等等。
这里用户终端当前所在 3GPP网络小区是指用户终端当前所在位置所属的 3GPP网络小区。 该小区标识可以是用户终端在接入非 3GPP接入网络的过程 中上报给非 3GPP接入网络, 或在位置报告消息中上报给 ANDSF的, 也可以 是配置在非 3GPP接入网络中的。
步骤 102、 获取该用户终端接入非第三代伙伴计划 3GPP接入网络时的接 入网络标识;
用户终端接入非 3GPP接入网络时的接入网络标识是指用户终端实际接入 3GPP核心网时采用的非 3GPP接入网络的标识。 该接入网络标识可以是配置 在非 3GPP接入网络中的, 也可以是在用户终端选择非 3GPP网络接入点后, 由用户终端主动向 ANDSF上报的。 因此在获取该接入网絡标识时, 可以是从 本地获取, 也可以从用户终端上报的位置报告中解析获取到, 对于 ANDSF还 可以接收非 3GPP接入网络系统上报的位置报告消息, 并解析该位置报告消息 获得用户终端接入网络时的非 3GPP接入网络标识,还可以通过其他的获取方 法获取, 其具体的实现方法并不造成对本发明的限制。
可以理解, 步骤 102和 101并没有绝对的顺序关系, 可以同时执行, 也可 以顺序执行。 在执行完步骤 101和 102后可以执行步骤 103a, 也可以执行步 骤 103b。
步骤 103a、 将步骤 101 中获得的 3GPP 网络小区的小区标识与步骤 102 中获得的非 3GPP接入网络的接入网络标识的映射关系信息发送给第三代伙伴 计划 3GPP核心网的鉴权、授权和计费服务器(以下简称 AAA服务器), 以便 鉴权、授权和计费服务器将映射关系信息发送给数据网关, 并和数据网关分别 根据映射关系信息进行相应的业务处理流程, 比如, 根据映射关系信息, 和相 应的计费策略生成计费话单; 根据映射关系信息进行合法监听等业务处理。
将 3GPP网络小区的小区标识和非 3GPP接入网絡的标识进行绑定得到映 射关系信息后, 可以在用户终端的鉴权过程中, 由非 3GPP接入网絡将该映射 关系信息发送给 AAA服务器; 也可以是由 ANDSF在位置报告过程中发送给 AAA服务器; 还可以在用户终端在建立会话后, 由非 3GPP接入网络携带在 计费数据请求消息中发送给 AAA服务器。 而 AAA服务器会将该映射关系信息发送给数据网关, 这样 AAA服务器 和数据网关会根据该映射关系信息, 进行后续相应的业务处理流程, 比如, 根 据映射关系信息和相应的计费策略生成计费话单。
在生成计费话单的过程中, 对于 AAA服务器是用来生成用户终端从非 3GPP接入网络接入时的所有业务的计费话单; 而数据网关是用来生成经过 3GPP核心网业务的计费话单。 它们的计费策略可以由 3GPP小区信息统一, 即依据 3GPP小区信息和非 3GPP接入网络标识的映射关系, 在这两者间实现 统一的计费策略。
例如: 映射关系信息为: 非 3GPP接入网络标识为家庭 WLAN网络标识 A,而 3GPP网络小区的小区标识为此家庭 WLAN网络所在的 3GPP宏网络小 区 B , 则 AAA服务器和数据网关都可以根据运营商为 3GPP宏网絡小区 B统 一制定的计费策略生成该用户终端的计费话单。
其中的数据网关可以为 PDG, 也可以为分组数据网网关 ( Packet Data Network Gateway, PGW ), 还可以为通用分组无线业务网关支持点 (Gateway GPRS Support Node GPRS, GGSN )„ 数据网关具体是哪个设备取决于用户终 端接入什么样架构的 3GPP核心网,例如:用户终端通过 WLAN系统接入 PDG 架构的核心网, 则数据网关为 PDG等。
可以理解, 非 3GPP接入网络或 A DSF可以储存绑定的 3GPP网络小区 的小区标识与非 3GPP接入网络标识的映射关系信息, 对用户终端当前所在 3GPP网络小区和非 3GPP接入网络位置进行对应地综合管理; 当用户终端位 置发生切换时, 可以根据切换后的网络进行更新该映射关系信息。
步骤 103b、 根据步骤 101 中获得 3GPP网络小区的小区标识与步骤 102 中获得的非 3GPP接入网络标识的映射关系信息进行相应的业务处理如下发接 入策略等。
可以理解, 当 A DSF在得到映射关系信息后, 可以将其中 3GPP网络小 区的小区标识对应的接入策略,及非 3GPP接入网络标识对应的接入策略下发 给用户终端, 这样用户终端可以根据这两种接入策略进行后续的接入网络选 择。 这时用户终端接入非 3GPP接入网络时的接入网络标识可能会发生变化, 用户终端可以将变化后的映射关系信息上报。 例如: 映射关系信息为: 非 3GPP接入网络标识为家庭 WLAN接入网络 标识 A, 而 3GPP网络小区的小区标识为此家庭 WLAN网络所在的 3GPP宏 网絡小区 B, 则 A DSF可以为用户终端下发对应的接入策略, 用户终端可以 根据运营商为 3GPP宏网络小区 B统一制定的接入策略进行后续的接入网络选 择。
可见, 本发明实施例的业务处理方法包括: 获取用户终端当前所在 3GPP 网络小区的小区标识; 并获取该用户终端接入非 3GPP接入网络时的接入网络 标识; 根据 3GPP网络小区的小区标识与非 3GPP接入网络标识的映射关系信 息进行业务处理,或将该映射关系信息发送给 3GPP核心网中的 AAA服务器, 这样 AAA服务器再将映射关系信息发送给数据网关, 则 AAA服务器和数据 网关会根据映射关系信息进行后续相应的业务处理流程, 比如, 根据映射关系 信息, 及各自的计费策略生成计費话单等,使得在业务处理时考虑用户终端当 前非 3GPP接入网络位置和当前所在 3GPP网络小区的映射关系, 进行统一处 理, 提高了用户终端从非 3GPP接入网络过程中的业务处理准确度, 实现运营 商对 3GPP和非 3GPP系统的统一管理。
在一个具体的实施例中, 具体地, 在执行上述步骤 101的获取 3GPP网絡 小区的小区标识时, 可以接收用户终端上报的位置报告或扩展的鉴权协议消 息, 并解析该用户终端上报的位置报告或扩展的鉴权协议消息获得当前所在 3GPP 网絡小区的小区标识; 也可以提取本地储存的用户终端当前所在 3GPP 网络小区的小区标识; 还可以通过有其它主动获取方式获取; 或,
接收非 3GPP接入网络发送的位置报告消息, 并解析该位置报告消息获得 用户终端当前所在第三代伙伴计划 3GPP网络小区的小区标识。
而在另一个具体的实施例中,在执行上述步骤 101的获取 3GPP网络小区 的小区标识时,可以接收用户终端上报的当前所在 3GPP网络小区的小区标识; 并在预置时间对上报的小区标识进行统计,根据统计结果选择上报的其中一个 小区标识作为用户终端当前所在 3GPP网络小区的小区标识, 比如选择上报次 数最多的 3GPP网络小区的小区标识, 作为该用户终端当前所在 3GPP网络小 区的小区标识。
在一段时间内上报某一小区标识的次数最多, 说明该小区标识对应的 3GPP网络小区信号比较稳定, 将该小区标识作为当前用户终端所在 3GPP网 络小区的小区标识是比较可信的。
方法实施例二
一种业务处理方法, 本发明实施例的方法适用于当用户终端通过非 3GPP 接入网络接入 3GPP核心网的过程中, 流程图如图 2所示, 包括:
步骤 201、 接收携带映射关系信息的消息, 映射关系信息包括: 用户终端 当前所在第三代伙伴计划 3GPP网络小区的小区标识, 与用户终端接入非第三 代伙伴计划 3GPP接入网络时的接入网络标识;
可以理解, 当用户终端从非 3GPP接入网络接入 3GPP核心网的过程中, 一些功能实体会根据映射关系信息进行相应的业务处理,如 3GPP核心网中的 数据网关和 AAA服务器都会生成各自的计费话单, 也可能会进行合法监听, 本实施例的方法就是这些业务功能实体如数据网关、 AAA服务器所执行的方 法。
而接收携带映射关系信息的消息可以是在用户终端接入非 3GPP接入网络 的鉴权过程中, 由 AAA服务器接收非 3GPP接入网络发送的携带映射关系信 息的鉴权与授权请求消息, 或接收 ANDSF发送的携带映射关系信息的位置报 告消息, 或接收非 3GPP接入网络发送的携带映射关系的计费数据请求消息; 也可以是由数据网关接收 AAA服务器发送的携带映射关系信息的鉴权与 授权应答消息或计费数据请求消息;
还可以是由 PCRF接收数据网关发送的携带映射关系信息的网络协议连 接接入网络会话建立请求消息。
步骤 202、 根据小区标识与接入网络标识的映射关系信息进行相应的业务 处理。 在步骤 201 接收到携带映射关系信息的消息后, 可以不马上进行步驟 202, 可以将映射关系信息进行储存, 在后续的业务处理中用到映射关系信息, 比如, 通过鉴权过程中接收到的消息中的映射关系信息, 先进行储存, 在之后 的计费过程中可以用到; 而对于通过计费数据请求消息接收的映射关系信息, 则需要在接收到消息就根据映射关系信息进行计费处理。
对于数据网关, 可以是在用户终端接入 3GPP核心网的鉴权过程中, 或在 用户终端在建立非 3GPP会话后的计费请求过程中, 接收由 AAA服务器发送 的映射关系信息, 并根据映射关系信息, 及与经过 3GPP核心网业务相关的计 费策略, 生成该用户终端经过 3GPP核心网业务的计费话单; 也可以根据映射 关系信息进行合法监听等业务。
对于 AAA服务器, 可以是在用户终端接入 3GPP核心网的鉴权过程中, 或在用户终端在建立非 3GPP会话后的计费请求过程中, 接收由非 3GPP接入 网络或 ANDSF发送的映射关系信息, 并根据映射关系信息, 及与用户终端从 非 3GPP接入网络的业务相关的计費策略, 生成该用户终端从非 3GPP接入网 络的业务的计费话单; 也可以根据映射关系信息进行合法监听等业务。
可以理解, 对于 AAA服务器, 需要将接收的小区标识与接入网络标识的 映射关系信息携带在鉴权与授权应答消息中发送给数据网关 ,这样数据网关可 以根据映射关系信息, 及本地相应的计费策略生成计费话单, 或者进行其他的 业务处理。
其中的数据网关可以为 PDG, 也可以为 PGW, 还可以为 GGSN。 数据网 关具体是哪个设备取决于用户终端通过非 3GPP接入网络接入什么样构架的 3GPP核心网的 ,例如:用户终端通过 WLAN接入网络接入 PDG构架的 3GPP 核心网 , 则数据网关为 PDG等。
可见, 本实施例的业务处理方法包括: 根据接收的用户终端当前所在的 3GPP网络小区的小区标识和非 3GPP接入网络标识的映射关系信息, 进行相 应的业务处理, 这样在业务处理时会考虑用户终端当前非 3GPP接入网络位置 和当前所在 3GPP 网络小区这两个因素进行统一处理, 提高了用户终端从非 3GPP接入网络过程中的业务处理准确度, 实现运营商对 3GPP和非 3GPP系 统的统一管理。
方法实施例三
一种业务处理方法, 本实施例中适用于用户终端通过 WLAN接入网络接 入演进的分组数据网关 (Evolved Packet Data Gateway, ePDG )构架的 3GPP 核心网的过程中的计费话单生成方法,及策略计费控制策略( PCC )下发方法, 该实施例中数据网关为 PGW, 且通过隧道建立的方式上报映射关系信息给 AAA服务器:
参考图 3 的结构示意图, 在 3GPP 网络中包括: 策略计费规则功能实体 ( Policy Charging Rule Function, PCRF )、分组数据网网关( Packet Data Network Gateway, PGW ), AAA服务器、 HSS、 网络业务服务器、 服务网关和 3GPP 接入。 其中 PGW、 网络业务服务器和服务网关可以通过与 PCRF的连接, 获 得相应的计费策略规则; AAA服务器与 HSS的交互实现对用户终端的鉴权、 授权操作, 并生成计费信息等。
当用户终端在非 3GPP网络中通过 WLAN接入网络接入到 3GPP核心网 后, 通过 ePDG与数据网关 PGW连接。
本实施例的业务处理方法流程图如图 4所示, 包括:
301、 用户终端通过 WLAN接入网络接入, 通过与 AAA服务器和 HSS的 交互执行鉴权过程。 在这个过程中, WLAN接入网络获得该用户终端当前所 在 3GPP网絡小区的小区标识, 并绑定该用户终端在非 3GPP接入网络标识, 将小区标识和接入网络标识的映射关系信息一起注册到 AAA服务器。具体地, WLAN接入网络是将映射关系信息通过与 AAA服务器的交互消息发送给 AAA服务器, 具体地, 可以添加到鉴权与授权请求消息的头域, 或值域中发 送给 AAA服务器, 由 AAA服务器进行储存, 并可以根据储存的映射关系信 息进行后续的业务处理。
WLAN接入网络在获得用户终端当前所在 3GPP网络小区的小区标识时, 可以接收用户终端发送的扩展的鉴权协议( Extensible Authentication Protocol, EAP )消息,并解析该 EAP消息的头域或值域得到 3GPP网络小区的小区标识。
302、 用户终端通过与 ePDG、 AAA服务器和 HSS的交互进行第二版因特 网密钥交换( Internet Key Exchange version 2, IKEv2 ) 鉴权及隧道建立过程。 在此过程中, AAA服务器将接收到的映射关系信息通过与 ePDG的交互消息 发送给 ePDG, 具体地, 可以携带在鉴权与授权应答消息中发送给 ePDG。
303、 核心网隧道建立过程。 ePDG发送代理绑定建立请求消息 ( Proxy Binding Update )给 PGW, 其中, 可以用该消息的头域或值域携带获取的映射 关系信息。
304、 PGW可以从 PCRF获得需要执行的策略计费控制策略, 并执行连接 接入网络会话的计费过程。
可以理解, 在此过程中, PGW可以发起网络协议连接接入网络( IP-CAN ) 会话建立过程, 在 IP-CA 会话建立请求消息中, 携带映射关系信息, 并将 IP-CAN会话建立请求消息发送给 PCRF, 则 PCRF可根据此映射关系信息, 将映射关系信息中的 3GPP网络小区对应的 PCC规则通过 IP-CAN会话建立应 答消息, 发送给 PGW。
这样 PGW在执行接入网络会话的计费过程中, 进行统一的对 3GPP网络 小区及非 3GPP接入网络的用户终端的计费, 提高了用户终端从非 3GPP接入 网络过程中的 PCC 计费的准确度, 满足运营商根据位置区分计費和非 3GPP 系统和 3GPP系统统一计费的需求。
305、PGW通过 AAA服务器将自己的信息注册到 HSS。如果上述步骤 303 中 ePDG没有将映射关系信息发送给 PGW,或步骤 302中 AAA服务器并没有 将映射关系信息发送给 ePDG,在本步骤中 AAA服务器通过与 PGW交互的消 息将映射关系信息发送给 PGW进行储存, 具体地, 可以将映射关系信息携带 在鉴权或授权应答消息进行发送。 PGW将在后续的业务处理中使用接收到的 位置映射关系。
可以理解, PGW会发送代理绑定请求消息( Proxy Binding Ack )给 ePDG, 在代理绑定建立成功之后 , 用户终端对 ePDG进行鉴权; 且 ePDG发送最终的 IKEv2消息, 携带 IP地址, 这样用户终端到 PGW之间的 IP连接已经建立。
306、 在生成话单的过程中, AAA服务器和 PGW根据该映射关系信息, 及各自相应的计费策略生成计费话单。
需要说明的是, 在本实施例的过程中, 在步骤 301 中, 当用户终端通过
WLAN接入网络接入 3GPP核心网中时, 可以不用通过 WLAN接入网络将映 射关系信息发送给 AAA服务器, 而是由用户终端通过 A DSF将映射关系信 息发送给 AAA服务器。 参考图 5所示, 具体可以通过如下步骤实现:
307、用户终端发送位置报告到 ANDSF,在位置报告中包括用户终端当前 所在 3GPP网絡小区的小区标识, 及该用户终端接入非 3GPP接入网络时的接 入网络标识的映射关系信息。
308、 可选地, A DSF发送位置艮告确认消息给用户终端。
309、 A DSF根据位置报告, 获得映射关系信息, 并可以进行储存。
310、 ANDSF 发送位置报告给 AAA服务器, 将此映射关系信息注册到 AAA服务器。
311、 AAA服务器返回位置报告确认给 A DSF。
这样, 通过另外一个设备 ANDSF来上报映射关系信息, 使得可以减轻非 3GPP接入网络即 WLAN接入网络的负担, 使得 WLAN接入网络中的其它功 能不受影响。
本实施例中, 3GPP核心网中的数据网关和 AAA服务器在隧道建立过程 中接收到映射关系信息, 根据映射关系信息及相应的计费策略生成计费话单, 这样在计费话单生成时会考虑用户终端当前非 3GPP接入网络位置和当前所在 3GPP网络小区这两个因素进行统一处理, 提高了用户终端从非 3GPP接入网 络过程中的计费话单生成准确度。 在本实施例中, 3GPP核心网中的数据网关 还会根据映射关系信息与 PCRF交互, 获得准确的 PCC规则, 同时也实现运 营商对 3GPP系统和非 3GPP系统统一控制的需求。
方法实施例四
一种业务处理方法, 本实施例中适用于用户终端通过 WLAN接入网络接 入隧道边界网关 (Tunnel Termination Gateway, TTG ) —GGSN构架的 3GPP 核心网的过程中的计费话单生成方法, 该实施例中数据网关为 GGSN, 且通过 隧道建立的方式上报映射关系信息给 AAA服务器:
参考图 6 的结构示意图, 在 3GPP 网络中包括: PCRF、 TTG, GGSN, AAA服务器、 HSS、 网络业务服务器、 服务网关和 3GPP接入。 其中 TTG和 GGSN共同实现图 3中 PGW的功能, 二者之间通过 GPRS隧道协议( GPRS Tunneling protocol, GTP )联系; TTG、 网络业务服务器和服务网关可以通过 与 PCRF的连接, 获得相应的计费策略规则; AAA服务器与 HSS的交互实现 对用户终端的健全授权操作, 并生成计费信息等。
当用户终端在非 3GPP接入网络中通过 WLAN接入网络接入到 3GPP核 心网后, 通过 TTG与数据网关 GGSN连接。
本实施例的业务处理方法流程图如图 7所示, 包括:
401、 用户终端通过 WLAN接入网络接入, 并通过与 AAA服务器和 HSS 的交互执行鉴权授权过程。 在这个过程中 WLAN 获得该用户终端当前所在 3GPP网路小区的小区标识, 并绑定该用户终端的非 3GPP接入网络标识, 将 小区标识和接入网络标识的映射关系信息通过鉴权与授权请求消息发送给 AAA服务器进行储存。
402、 用户终端通过 TTG、 AAA服务器和 HSS的交互进行 IKEv2鉴权及 隧道建立过程。 在此过程中, AAA服务器将接收到的映射关系信息携带在鉴 权与授权应答消息中发送给 TTG。
403、 核心网隧道建立过程。 在这个过程, TTG发送分组数据协议上下文 激活请求消息( activate PDP context request )给 GGSN, 其中携带 TTG获得的 映射关系信息。
404、 GGSN回复分组数据协议上下文激活响应消息给 TTG。
405、 在生成话单的过程中, AAA服务器和 GGSN根据该映射关系信息, 及各自相应的计费策略生成计费话单。
需要说明的是, 在本实施例的过程中, 在步骤 401 中, 当用户终端通过 WLAN接入网络接入 3GPP核心网中时, 可以不用通过 WLAN接入网络将映 射关系信息发送给 AAA服务器, 而是由用户终端通过 A DSF将映射关系信 息发送给 AAA服务器。 具体的过程可以如图 5所示, 在此不再赘述。
方法实施例五
一种业务处理方法, 本实施例中适用于用户终端通过 WLAN接入网络接 入 PDG构架的 3GPP核心网的过程中的计费话单生成方法, 该实施例中数据 网关为 PDG, 且通过隧道建立的方式上报映射关系信息给 AAA服务器:
参考图 8的结构示意图, 在 3GPP网络中包括, PCRF、 PDG, AAA服务 器、 HSS、 网絡业务服务器、 服务网关和 3GPP接入。 其中 PGW、 网络业务 服务器和服务网关可以通过与 PCRF的连接,获得相应的计费策略规则; AAA 服务器与 HSS的交互实现对用户终端的健全授权操作, 并生成计费信息等。
当用户终端在非 3GPP网络中通过 WLAN接入网絡接入到 3GPP核心网 后, 直接与数据网关 PDG连接。
本实施例的业务处理方法流程图如图 9所示, 包括:
501、 用户终端通过 WLAN接入网络接入, 通过与 AAA服务器和 HSS的 交互执行鉴权授权过程。 在这个过程中, WLAN接入网络获得该用户终端当 前所在 3GPP网路小区的小区标识, 并绑定该用户终端的非 3GPP接入网络标 识,将小区标识和接入网络标识的映射关系信息通过鉴权与授权请求消息发送 给 AAA服务器进行储存。
502、 用户终端通过与 PDG、 AAA服务器和 HSS的交互进行 IKEv2鉴权 及隧道建立过程。 在此过程中, AAA服务器将接收到的映射关系信息携带在 鉴权与授权应答消息中发送给 PDG。
503、 在生成话单的过程中, AAA服务器和 PGW根据该映射关系信息, 及各自相应的计费策略生成计费话单。
需要说明的是, 在本实施例的过程中, 在步骤 501 中, 当用户终端通过 WLAN接入网络接入 3GPP核心网中时, 可以不用通过 WLAN接入网络将映 射关系信息发送给 AAA服务器, 而是由用户终端通过 A DSF将映射关系信 息发送给 AAA服务器。 具体的过程可以如图 5所示, 在此不再赘述。
方法实施例六
一种业务处理方法, 本实施例中适用于用户终端通过 WLAN接入网络接 入 3GPP核心网的过程中, 该实施例中是在计费请求过程中上报映射关系信息 给 3GPP核心网中的 AAA服务器, 方法流程图如图 10所示, 包括:
601、 用户终端与 AAA服务器建立 WLAN会话的过程。
602、 WLAN接入网络发送计费数据请求消息 ( Charging Data request )开 始消息给 AAA服务器。 WLAN接入网络获得该用户终端当前所在 3GPP网路 小区的小区标识, 并绑定该用户终端的非 3GPP接入网络标识, 得到小区标识 和接入网络标识的映射关系信息,并将映射关系信息携带在计费数据请求消息 开始消息中一起发送给 AAA服务器。
603、 3GPP核心网中的 AAA服务器将接收到的计费数据请求开始消息转 化为计费数据请求消息,并发送给计费数据功能实体( Charging Data Function, CDF )。 在计费数据请求消息中携带映射关系信息。
604、 CDF打开一个 WLAN的计费数据记录( Charging Data Record, CDR ), 即生成计费话单, 并将接收到的计费数据请求消息中的信息携带在 CDR中, 该信息包括映射关系信息。
可以理解, CDF 可以确认接收到计费数据请求消息, 发送计费数据响应 消息给 AAA服务器; AAA服务器将计费数据响应消息转化为计费数据应答消 息, 发送给 WLAN接入网络。
605、 AAA良务器可以将获得的映射关系信息添加到计费数据请求消息中 发送给数据网关, 则数据网关根据该映射关系信息, 及各计费策略生成计费话 单。
这里的数据网关为哪个设备取决于用户终端从 WLAN接入网络接入什么 构架的 3GPP核心网中。
本实施例中, 3GPP核心网中的 AAA服务器在计费请求过程中接收到映 射关系信息, 并将此映射关系信息在后续流程中发送给数据网关, AAA服务 器和数据网关根据映射关系信息及相应的计费策略生成计费话单,这样在计费 话单生成时会考虑用户终端当前非 3GPP接入网络位置和当前所在 3GPP网络 小区这两个因素进行统一处理,提高了用户终端从非 3GPP接入网络过程中的 计费话单生成准确度, 也实现了运营商才艮据位置计费及统一计费的需求。数据 网关还会根据映射关系信息进行后续业务处理,比如其他实施例中所提到的与 PCRF交互, 获得 PCC规则, 合法监听等, 过程在这里不再赘述。
方法实施例七
一种业务处理方法,本实施例适用于用户终端通过非 3GPP接入网络接入 3GPP核心网的过程中的合法监听方法, 具体方法流程图如图 11所示, 包括: 701、 监听系统中管理功能实体 ( Administration Function, AMNF )接收 到客户端发送的合法监听激活的请求。
702、 AMNF 发送监听的地点给 3GPP核心网中的数据网关如 PGW/PDG, 和 AAA服务器, 此地点可以为需要监听的 3GPP网络小区的小区标识。
703、 数据网关和 AAA服务器, 可以获取到本地储存的用户终端所在 3GPP网络小区的小区标识, 与用户终端接入非 3GPP接入网络的接入网络标 识的映射关系信息;并将接收的监听地点与本地储存的映射关系信息进行比较 匹配, 获得监听地点对应的非 3GPP接入网络标识。
可以理解,本地储存的映射关系信息的获得方法如前述实施例中获得映射 关系信息的方法, 比如在隧道建立的过程中, 接收由非 3GPP接入网络发送的 映射关系信息等等, 在此不再赘述。
704、 数据网关和 AAA服务器根据获得的映射关系信息, 对该映射关系 信息中的该用户终端当前所在 3GPP网络小区和非 3GPP接入网络中的业务进 行合法监听, 并将监听结果发送给 AMNF。
705、 AMNF回复合法监听激活的请求。
本实施例中, 3GPP核心网中的数据网关和 AAA服务器获得映射关系信 息,根据映射关系信息和监听地点确定需要监听的位置, 并对用户终端的业务 进行合法监听, 这样在合法监听时会考虑用户终端当前非 3GPP接入网络位置 和当前所在 3GPP 网络小区这两个因素进行统一处理, 提高了用户终端从非 3GPP接入网络过程中的合法监听准确度。
方法实施例八
一种业务处理方法, 本实施例适用于用户终端通过与 A DSF的交互获得 网絡接入策略的过程, 具体方法流程图如图 12所示, 包括:
801、 用户终端从非 3GPP接入网络如 WLAN系统接入 3GPP核心网中。 在 这个过程中非 3GPP接入网络获得用户终端当前所在 3GPP网络小区的小区标 识, 可以通过非 3GPP接入网络主动向用户终端请求获取的, 也可以是用户终 端携带在 EAP消息中主动上报的。
非 3GPP接入网络可以提取本地的非 3GPP接入网絡标识。
802、 非 3GPP接入网络将用户终端当前所在 3GPP网络小区的小区标识, 和用户终端接入非 3GPP接入网络时的接入网络标识的映射关系信息携带在位 置报告消息中, 上报给 ANDSF进行储存。
803、 ANDSF才艮据映射关系信息,将与映射关系信息中 3GPP网络小区的小 区标识相关的第一接入策略, 和与非 3GPP接入网络标识相关的第二接入策略 一起通过非 3GPP接入网络下发给用户终端。 或者, ANDSF只根据 3GPP网络小 区的小区标识, 下发与之相关的第一接入策略给用户终端。
804、 用户终端综合第一接入策略和第二接入策略, 进行网络选择。 终端 可能会根据第一接入策略和第二接入策略重新选择接入 3GPP 核心网的非
3GPP接入网络例如第一接入策略为 3GPP网络小区 A中的用户终端接入网络 时的策略, 而第二策略为非 3GPP接入网络 B中用户终端接入网络时的策略, 则用户终端可以根据第一策略和 /或第二策略重新选择非 3GPP接入网络。
805、 如果用户重新选择了非 3GPP接入网络, 且与该用户终端之前接入 的非 3GPP接入网络不一致,则将更新的位置映射关系携带在位置 4艮告消息中, 上报给 ANDSF进行更新储存。
本实施例中, 在用户终端接入网络时, 在用户终端和 A DSF的交互过程 中, ANDSF接收到映射关系信息, 根据映射关系信息下发接入策略给用户终 端, 这样用户终端在选择非 3GPP接入网络时会考虑用户终端当前非 3GPP接 入网络位置和当前所在 3GPP网络小区这两个因素进行统一处理,提高了用户 终端从非 3GPP接入网络过程中的接入网络的准确度。 也可以实现运营商对 3GPP系统和非 3GPP系统的统一管理, 同时节约了策略维护成本。

且网络设备还可以包括映射储存单元 13, 用于储存和 /或更新小区获取单 元 10的选择单元 120获取的小区标识与接入获取单元 11获取的接入网络标识 的映射关系信息。
本实施例中当上报接收单元 110接收到用户终端上报的小区标识后,选择 单元 120在上报的小区标识中选择一个小区标识作为用户终端当前所在 3GPP 网络小区的小区标识,这样小区获取单元 10获取得到的小区标识对应的 3GPP 网络小区信号比较稳定, 比较可信。
设备实施例二
一种业务处理设备, 本实施例中的装置可以是数据网关, 也可以是 ANDSF, 还可以是其它的一些功能实体, 结构示意图如图 15所示, 包括: 映射接收单元 20, 用于接收携带映射关系信息的消息, 映射关系信息包 括: 用户终端当前所在第三代伙伴计划 3GPP网络小区的小区标识, 与用户终 端接入非第三代伙伴计划 3GPP接入网络时的接入网络标识;
