Description

IP分流计费信息的获取方法和系统 技术领域
本发明涉及移动通信领域， 尤其涉及一种 IP分流计费信息的获取方法和 系统。
背景技术
第三代合作伙伴计划 （ 3rd Generation Partnership Project, 简称为 3GPP ) 演进的分组系统（ Evolved Packet System , 简称为 EPS ) 由演进的通用移动 通信系统陆地无线接入网 （ Evolved Universal Terrestrial Radio Access Network, 简称为 E-UTRAN ) 、 移动管理单元（ Mobility Management Entity, 简称为 MME ) 、 服务网关 （ Serving Gateway, S-GW ) 、 分组数据网络网关 ( Packet Data Network Gateway, 简称为 P-GW或者 PDN GW)、 归属用户服 务器 （Home Subscriber Server , 简称为 HSS ) 、 3GPP 的认证授权计费 ( Authentication、 Authorization and Accounting , 简称为 AAA )月良务器， 策略 和计费规则功能（ Policy and Charging Rules Function, 简称为 PCRF ) 实体及 其他支撑节点组成。 图 la是根据相关技术的 EPS系统架构的示意图，移动性 管理实体负责移动性管理、 非接入层信令的处理和用户移动管理上下文的管 理等控制面的相关工作； S-GW是与 E-UTRAN相连的接入网关设备， 在 E-UTRAN和 P-GW之间转发数据，并且负责对寻呼等待数据进行緩存； P-GW 则是 EPS与分组数据网络（ Packet Data Network, 简称为 PDN ) 网络的边界 网关， 负责 PDN的接入及在 EPS与 PDN间转发数据等功能； S-GW和 P-GW 都属于核心网网关。
家用基站是一种小型、低功率的基站， 部署在家庭及办公室等室内场所， 主要作用是为了给用户提供更高的业务速率并降低使用高速率服务所需要的 费用， 同时弥补已有分布式蜂窝无线通信系统覆盖的不足。 家用基站的优点 是实惠、 便捷、 低功率输出、 即插即用等。 在家用基站系统中， 家用基站为 无线侧网元。 家用基站可以直接连接到核心网络， 如图 la所示， 也可以通过 家用基站网关这个逻辑网元接入到核心网络， 如图 lb所示， 其中， 家用基站 网关主要功能为： 验证家用基站的安全性， 处理家用基站的注册， 对家用基 站进行运行维护管理， 根据运营商要求配置和控制家用基站， 负责交换核心 网和家用基站的数据。
除了支持移动核心网络的接入以外， 移动通信系统（包括家用基站系统） 还可支持互联网协议（IP )分流功能， 在无线侧网元具备 IP分流能力以及用 户签约允许 IP分流的条件下， 可实现终端对家用网络其他 IP设备或者互联 网络的本地接入。
IP分流的实现可以通过增设本地网关的方式来提供对数据分流技术的有 力支持， 本地网关作为本地接入到外部网络（例如 Internet )的网关， 提供地 址分配、 计费、 分组包过滤、 策略控制、 数据分流功能、 NAS/S1-AP/RANAP ( Radios Access Network Application Part,无线接入网应用 分 )/GTP( General Tunneling Protocol, 通用隧道协议） /PMIP ( Proxy Mobile IP, 代理移动 IP协 议） /MIP ( Mobile IP, 移动 IP协议） 消息解析、 NAT ( Network Address Translation, 网络地址转换）、 IP分流策略路由和执行等功能。 本地网关可与 无线侧网元进行合设（如图 la、 图 lb和 2a所示） 。 当存在家用基站网关的 情况下， 本地网关不仅可与家用基站进行合设， 也可与家用基站网关进行合 设（如图 2b所示） 。 本地网关可以是 L-SGW (本地 SGW, Local SGW )和 L-PGW (本地 PGW, Local PGW ) , 可以是单独的 L-PGW, 可以是数据分 流功能实体， 也可以是 NAT网关。 此外， 家用基站网关可以与家用基站进行 合设。 对于 UTRAN ( Universal Terrestrial Radio Access Network, 通用陆地无 线接入网络） 系统， 核心网网关可以是 SGSN (服务通用分组无线业务支持 节点， Serving GPRS Support Node ) 、 GGSN (网关通用分组无线业务支持节 点， Gateway GPRS Support Node )。 本地网关可以是 L-GGSN (本地 GGSN, Local GGSN )和 L-SGSN(本地 SGSN, Local SGSN ) ,可以是单独的 L-GGSN, 可以是数据分流功能实体， 也可以是 NAT网关。
以 LTE ( Long Term Evolution, 长期演进）移动通信网络架构为例， 图 3a和图 3b分别显示了在图 la和图 2a的无线通信系统中 IP分流和核心网连 接的示意数据流。
基于图 la的系统架构、 本地接入网关为 L-SGW和 L-PGW的场景， 图 4 显示了现有技术中核心网连接计费信息获取过程的流程图。 具体步骤描述如 下：
步骤 401 , 终端接入无线通信系统后具有核心网连接。
步骤 402, S-GW对核心网连接的信息（如流量、 时长）进行收集， 并生 成计费数据记录。
步骤 403 , S-GW将计费数据记录发送给计费系统。
步骤 404, 计费系统接收并处理核心网连接的计费数据记录， 便于执行 账单管理和信息统计操作。
由上述流程可见以及图 3a可见， 存在 IP分流连接的情况下， 终端 IP分 流数据流由无线侧网元或家用基站网关直接发往互联网， 而不会经过核心网 网关， 如 S-GW、 P-GW, 此时， 核心网网关无法对 IP分流连接的进行计费 信息统计， 同时无线侧网元或家用基站网关与移动性管理实体之间不存在计 费信息传递等问题， 导致无法对终端的 IP分流连接进行计费处理。

其中， 核心网网元为移动性管理实体和 /或核心网网关； 核心网网关为核 心网月良务网关和 /或核心网接入网关。
下面结合附图及具体实施例对本发明进行详细说明。 以下实施例中， 图 5a、 图 5b和图 6描述了基于 E-UTRAN系统的应用场 景。
图 5a在图 la系统架构的基础上， 提供的对终端 IP分流连接获取计费信 息过程的流程图。 该实施例中 IP分流点位于无线侧网元、 由无线侧网元生成 计费数据记录， 具体步骤描述如下：
步骤 5a01 , 终端接入无线通信系统后具有核心网连接， 该连接允许进行 IP分流。
步骤 5a02,无线侧网元对 IP分流连接的信息（如流量、时长）进行收集， 并生成 IP分流的计费数据记录。
步骤 5a03 , 无线侧网元将计费数据记录发送给移动性管理实体， 可以携 带 S-GW的标识信息。
步骤 5a04, 移动性管理实体将该 IP分流的计费数据记录发送给 S-GW。 如果步骤 5a03未携带 S-GW的标识信息，则移动性管理实体将选择核心 网连接对应的核心网 S-GW或者根据本地策略选择某个核心网 S-GW, 或根 据接收的信息类型进行选择。
其中， 根据接收的信息类型进行选择具体是指， 当移动性管理实体判断 接收到信息的类型为发送 IP分流计费信息的消息后， 则将该信息发送给指定 的某个核心网 S-GW。
步骤 5a05, S-GW向计费系统传送计费数据记录。
步骤 5a06,计费系统接收并处理 IP分流连接的计费数据记录，便于执行 账单管理和信息统计操作。
图 5b在图 la系统架构的基础上， 提供的对终端 IP分流连接获取计费信 息过程的流程图。 该实施例中 IP分流点位于无线侧网元、 由 S-GW生成计费 数据记录， 具体步骤描述如下：
步骤 5b01 , 终端接入无线通信系统后具有核心网连接， 该连接允许进行 IP分流。
步骤 5b02,无线侧网元对 IP分流连接的信息（如流量、时长）进行收集。 步骤 5b03 ,无线侧网元将已收集的 IP分流统计信息发送给移动性管理实 体， 可以携带 S-GW的标识信息。
步骤 5b04, 移动性管理实体将该收集的 IP分流统计信息发送给 S-GW。 如果步骤 5b03未携带 S-GW的标识信息，则移动性管理实体将选择核心 网连接对应的核心网 S-GW或者根据本地策略选择某个核心网 S-GW, 或根 据接收的信息类型进行选择。
步骤 5b05, S-GW才艮据收集的 IP分流统计信息生成计费数据记录， 向计 费系统传送计费数据记录。
其中， 根据 IP分流统计信息生成计费数据记录的过程为现有技术， 此处 不再详述。
步骤 5b06,计费系统接收并处理 IP分流连接的计费数据记录，便于执行 账单管理和信息统计操作。
为了简化描述， 以上所有实施例仅以 E-UTRAN系统图 la的情况为例来 说明对 IP分流信息的计费获取方式。 在图 2a的场景下， IP分流信息的计费 获取可以由无线侧网元或本地网关对 IP分流信息进行统计， 计费信息由无线 侧网元或本地网关发送给移动性管理实体， 传送途径以及计费记录的生成网 元与上述实施例极为相似， 不会对阐述本发明造成影响， 故在此不再重复描 述。
为了简化描述， 以上所有实施例仅以 E-UTRAN系统不存在家用基站网 关的情况为例来说明对 IP分流信息的计费获取方式。存在家用基站网关的情 况下， IP分流计费信息获取方式以及计费记录的生成网元与上述实施例极为 相似， 不会对阐述本发明造成影响， 故在此不再重复描述。
另夕卜， 上述实施例为优选实施例， 实际应用时， 无线侧网元可以将 IP分 流计费信息经移动性管理实体、 核心网 S-GW、 核心网 P-GW再发送给计费 系统， 也可以将 IP分流计费信息经移动性管理实体直接发送给计费系统， 等 等。 即 IP分流信息的计费获取可以由无线侧网元或本地网关对 IP分流信息 由移动性管理实体经核心网服务网元传送给核心网接入网关， 再由核心网接 入网关将计费数据记录发送给计费系统， 其中计费数据记录的生成网元可以 为无线侧网元或本地网关， 也可以为核心网服务网关或核心网接入网关。 若 存在家用基站网关的情况下， 无线侧网元先将 IP分流计费信息发送给家用基 站网关， 再由家用基站网关转发给核心网网元。
图 6在图 lb系统架构的基础上， 提供的对终端 IP分流连接获取计费信 息过程的流程图。 该实施例中 IP分流点位于家用基站网关， 具体步骤描述如 下：
步骤 601 , 终端接入无线通信系统后具有核心网连接， 该连接允许进行 IP分流。
步骤 602, 家用基站网关对 IP分流连接的信息 （如流量、 时长）进行收 集， 并生成计费数据记录。
步骤 603 , 家用基站网关将计费数据记录发送给移动性管理实体， 可以 携带 S-GW的标识信息。
步骤 604 , 移动性管理实体将该 IP 分流连接的计费数据记录发送给
S-GW。
如果步骤 603未携带 S-GW的标识信息， 则移动性管理实体将选择核心 网连接对应的核心网 S-GW或者根据本地策略选择某个核心网 S-GW, 或根 据接收的信息类型进行选择。
步骤 605, S-GW向计费系统传送计费数据记录。
步骤 606, 计费系统接收并处理 IP分流连接的计费数据记录， 便于执行 账单管理和信息统计操作。
为了简化描述， 以上实施例仅以 E-UTRAN系统图 lb由家用基站网关生 成计费数据记录的情况为例来说明对 IP分流信息的计费获取方式。 该系统中 也可以由家用基站网关收集 IP分流连接的信息且由 S-GW生成计费数据记录 来实现对 IP分流信息的计费获取方式， 与图 5b实施例计费记录生成网元极 为相似， 不会对阐述本发明造成影响， 故在此不再重复描述。
为了简化描述， 以上实施例仅以 E-UTRAN系统图 lb的情况为例来说明 对 IP分流信息的计费获取方式。 在图 2b的场景下， IP分流信息的计费获取 可以由家用基站网关或本地网关对 IP分流信息进行统计，计费信息由家用基 站网关或本地网关发送给移动性管理实体， 传送途径以及计费记录的生成网 元与上述实施例极为相似， 不会对阐述本发明造成影响， 故在此不再重复描 述。
另一实施例为， IP分流信息的计费获取可以由无线侧网元或本地网关对 IP分流信息进行统计， 计费信息由无线侧网元或本地网关发送给移动性管理 实体， 然后由移动性管理实体经核心网服务网元传送给核心网接入网关， 再 由核心网接入网关将计费数据记录发送给计费系统， 其中计费数据记录的生 成网元可以为无线侧网元或本地网关， 也可以为核心网月良务网关或核心网接 入网关。
以下实施例中， 图 7描述了基于 UTRAN系统的应用场景。
图 7在图 la系统架构的基础上， 提供的对终端 IP分流连接获取计费信 息过程的流程图。该实施例中 IP分流点位于无线侧网元，具体步骤描述如下： 步骤 701 , 终端接入无线通信系统后具有核心网连接， 该连接允许进行 IP分流。
步骤 702, 无线侧网元对 IP分流连接的信息（如流量、 时长）进行收集， 并生成计费数据记录。
步骤 703 , 无线侧网元将计费数据记录发送给移动性管理实体， 可以携 带计费系统的标识信息。
步骤 704, 移动性管理实体将该 IP分流连接的计费数据记录发送给计费 系统。
如果步骤 703未携带计费系统的标识信息， 则移动性管理实体将根据本 地策略选择计费系统， 或根据接收的信息类型进行选择。
步骤 705, 计费系统接收并处理 IP分流连接的计费数据记录， 便于执行 账单管理和信息统计操作。
以上实施例以 UTRAN系统图 la由无线侧网元生成计费数据记录的情况 为例来说明对 IP分流信息的计费获取方式。 此外， 该系统中也可以由无线侧 网元收集 IP分流连接的信息且由移动性管理实体 SGSN生成计费数据记录来 实现对 IP分流信息的计费获取方式： 无线侧网元将收集 IP分流连接的信息 发送给移动性管理实体 SGSN, 移动性管理实体 SGSN生成计费数据记录后 将该记录发送给计费系统。
为了简化描述， 以上实施例仅以 UTRAN系统图 la的情况为例来说明对 IP分流信息的计费获取方式。 在图 lb、 2a、 2b的场景下、 或 E-UTRAN系统 下、 或存在家用基站网关的情况下， IP分流信息的计费获取可以由无线侧网 元、 或家用基站网关、 或本地网关对 IP分流信息进行统计， 计费信息由其发 送给移动性管理实体， 传送途径以及计费记录的生成网元与上述实施例极为 相似， 不会对阐述本发明造成影响， 故在此不再重复描述。
另外， 本实施例为优选实施例， 无线侧网元、 或家用基站网关、 或本地 网关可以将 IP分流计费信息经移动性管理实体和核心网网关再发送给计费系 统， 以及， 可以由移动性管理实体或核心网网关根据 IP分流统计信息生成计 费数据记录， 等等。 此处不再赘述。
