一种隐藏拜访地网络拓朴结构的策略计费控制的方法
技术领域
本发明涉及无线网络中的一种隐藏拜访地网络拓朴结构的策略计费控制 的方法。
背景技术
3GPP演进的分组系统( EPS , Evolved Packet System ) 由演进的 UTRAN ( E-UTRAN, Evolved Universal Terrestrial Radio Access Network ) 、 MME (移 动管理单元, Mobility Management Entity ) 、 S-GW (服务网关, Serving Gateway ) 、 PDN GW(P-GW, Packet Data Network Gate Way, 数据网络网关)、 HSS (归属用户服务器, Home Subscriber Server ) 、 3GPP AAA服务器( 3GPP 认证授权计费服务器) , PCRF ( Policy and Charging Rules Function, 策略和 计费规则功能) , 及其他支撑节点组成。 其中 ΜΜΕ 负责移动性管理、 非接 入层信令的处理、 用户的移动管理上下文的管理等控制面相关工作; S-GW 是与 E-UTRAN相连的接入网关设备, 在 E-UTRAN和 PDN 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 3GPP演进的分组系统 ( EPS, Evolved Packet System )与 PDN ( Packet Data Network ) 网络的边界 网关, 负责 PDN的接入、 在 EPS与 PDN间转发数据等功能。 PCRF是策略 和计费规则功能实体, 它通过 Rx接口与运营商 IP业务网络接口, 获取业务 信息, 另一边它通过 Gx/Gxa/Gxc与网络中的网关设备相连, 负责发起 IP承 载的建立, 保证业务数据的 QoS, 并进行计费控制。
EPS支持与非 3GPP网络的互通。 与非 3GPP网络的互通通过 S2a/b/c接 口实现, P-GW作为 3GPP与非 3GPP网络间的锚点。 EPS的系统架构图如图 1所示。其中非 3GPP系统被分为可信任非 3GPP IP接入和不可信任非 3GPP IP 接入。可信任非 3GPP IP接入可直接通过 S2a与 P-GW接口;不可信任非 3GPP IP接入需经过 ePDG( Evolved Packet Data Gateway,演进的数据网关)与 P-GW 相连, ePDG与 P-GW间的接口为 S2b。
在 EPS之前的 3GPP网络中, 策略和计费执行功能(PCEF, Policy and
1 180800477 charging enforcement function )仅存在于 P-GW中, PCRF只要与 P-GW接口 即可完成策略计费控制, PCRF与 P-GW间通过 Gx接口(见图 1 )交换信息。 但是,在 EPS系统中,当 P-GW与 S-GW间的接口基于 PMIPv6时,由于 PMIPv6 协议的局限性, 不能传输策略计费控制信息, PCEF的部分功能, 例如承载绑 定和事件报告等功能, 迁移到了 S-GW 中, 称为承载绑定和事件报告功能
( BBERF , Bearer Binding and Event Reporting Function ) , S-GW与 PCRF之 间通过 Gxc接口 (见图 1 ) 交换信息。 当可信任非 3GPP接入系统通过 S2a 与 3GPP系统间互通接入时, 可信任非 3GPP接入网关中也驻留 BBERF (如 图 1 ) , 其通过 Gxa接口与 PCRF交换信息。 当 UE漫游时, S9接口作为家 乡网络 PCRF 和拜访地网络 PCRF 的接口。 同时为 UE 提供业务的 AF(Application Function, 应用功能)通过 Rx接口向 PCRF发送用于制定 PCC
( Policy and Charging Control, 策略和计费控制)策略的业务信息。 Gx, Gxa, Gxc以及 Rx接口都釆用 Diameter协议。
以上 PCEF、 BEERF、 vPCRF、 hPCRF等可视为功能模块或功能实体。 当用户漫游到拜访地时, 可以使用家乡路由(Home Routed )或是本地疏 导(LBO, Local BreakOut ) 两种方式接入 PDN 网络。 釆用 Home Routed的 方式, 用户使用家乡网络的 P-GW接入 PDN网络(如图 2所示); 釆用 LBO 方式, 用户使用拜访地的 P-GW接入 PDN网络(如图 3所示) 。 当 UE釆用 Home Routed方式漫游时,位于拜访地网络的 BBERF通过 vPCRF( visit PCRF ) 与 hPCRF ( home PCRF )进行交互。 当 UE釆用 LBO方式漫游时, 拜访地网 络的运营商希望能够隐藏自己的网络拓朴结构, 即对于 hPCRF来说拜访地网 络的 BBERF是不可见的。 vPCRF会终结 BBERF与 hPCRF的交互, 而只转 发拜访地网络 PCEF 与 hPCRF 的交互。 在 LBO 的漫游场景下, UE通过 E-UTRAN接入, S-GW与 P-GW釆用 PMIPv6协议或 UE通过可信任非 3GPP 接入网关, 釆用 PMIPv6协议接入时, 具体如何实现策略计费控制时隐藏拜 访地网络拓朴结构是个尚未解决的问题。

本发明的较佳实施方式
本发明为了解决传统技术方案存在的弊端, 通过以下具体实施例进一步 阐述本发明所述的一种隐藏拜访地网络拓朴结构的策略计费控制的方法, 以 下对具体实施方式进行详细描述, 但不作为对本发明的限定。 本实施例描述的是当 UE处于本地疏导漫游场景下, UE通过 E-UTRAN 接入并且 S-GW与 P-GW之间釆用 PMIPv6协议或 UE通过可信任非 3GPP接 入网釆用 PMIPv6协议接入时 IP-CAN会话建立流程图。本实施例如图 4所示, 各步骤描述如下:
401、 驻留有 BBERF的 S-GW或可信任非 3GPP接入网关接收到建立网
10 180800477 关控制会话请求消息。 当通过 E-UTRAN接入时 , 该消息为 MME发送的默 认承载建立请求消息, 当通过可信任非 3GPP接入网关接入时, 该消息为可 信任非 3GPP接入网中的层 3附着消息。消息中携带用户标识,如 NAI( Network Access Identifier, 网络接入标识) )和用户要接入的 PDN的标识, 如 APN ( Access Point Name, 接入点名 ) ;
本实施例及其他实施例中涉及的 S-GW或可信任非 3GPP接入网关均驻 留有 BBERF,用于完成策略计费控制相关的处理。 因此也可以写成是 BBERF 进行策略计费控制相关的消息收发及处理。对于其它驻留有 BBERF的设备也 可以应用本发明的方法完成策略计费控制。
402、 驻留有 BBERF的 S-GW或可信任非 3GPP接入网关选择拜访地网 络的 P-GW接入 PDN网络, 即用户釆用本地疏导的漫游方式。 向拜访地网络 vPCRF发送网关控制会话请求消息, 消息中携带用户标识和用户要接入的 PDN的标识以及 LBO指示;
在具体实现时, LBO指示可以是 P-GW所在网络的 ID, vPCRF可以将 自己所在网络的 ID与 LBO指示所带的 P-GW所在网络的 ID进行比较。若相 同, 用户釆用了 LBO的漫游方式, 若不相同, 用户釆用了 Home Routed的漫 游方式。 此处也可不经过 LBO中 ID比对来判断漫游方式, 也可以由其他方 式完成, 对于此处判断漫游方式的选择, 不影响本发明方案的执行。
403、vPCRF根据 LBO指示判断用户釆用了 LBO的漫游方式,并且 vPCRF 和 hPCRF之间不存在 IP-CAN会话, 因此 vPCRF根据本地策略和 /或漫游协 议制定 QoS规则和 /或事件触发器,并通过网关控制会话建立确认消息发送给 BBERF; S-GW或可信任非 3GPP接入网关安装 QoS规则和 /或事件触发器; 在另一实施例中, vPCRF也可不制定 QoS规则和事件触发器, 直接向 BBERF返回网关控制会话建立确认消息。 这取决于拜访地网络的本地策略; 404、 S-GW或可信任非 3GPP接入网关收到步骤 401中的建立网关控制 会话请求消息后, 向选择的拜访地网络驻留有 PCEF的 P-GW发送建立 IP- CAN会话请求消息, 消息中携带用户标识和用户要接入的 PDN的标识; 该步骤及后续相关步骤与步骤 402及 403可以并行, 没有固定的先后顺
11 180800477 序。
405、 P-GW (或者说是驻留于 P-GW的 PCEF ) 向 vPCRF发送 IP-CAN 会话建立指示消息, 消息中携带用户标识和用户要接入的 PDN的标识;
406、 vPCRF根据用户标识和用户要接入的 PDN的标识将 IP-CAN会话 和网关控制会话进行关联, 并向 hPCRF发送 IP-CAN会话建立指示消息;
407、 hPCRF根据用户的签约信息、 网络策略等进行决策, 制定 PCC规 则和事件触发器;
408、 hPCRF通过 IP-CAN会话建立确认消息向 vPCRF发送 PCC规则和 事件触发器;
409、 vPCRF向 P-GW发送 IP-CAN会话建立确认消息, 携带 PCC规则 和事件触发器。 vPCRF可能会根据本地策略对 hPCRF下发的 PCC规则和事 件触发器进行修改;
410、P-GW安装 PCC规则和事件触发器,然后向 S-GW或可信任非 3GPP 接入网关返回建立 IP-CAN会话应答消息;
411、 vPCRF根据 hPCRF下发的 PCC规则和事件触发器重新制定 QoS 规则和事件触发器, 若与之前下发给 BBERF的 QoS规则或事件触发器不同, 则 vPCRF通过网关控制和 QoS规则提供消息将新的 QoS规则和事件触发器 下发给 BBERF, 执行步骤 412; 若相同则无需下发, 直接执行步骤 413;
在另一实施例中, 在步骤 403中没有制定过 QoS规则和事件触发器, 则 此处 vPCRF根据 hPCRF下发的 PCC规则和事件触发器制定 QoS规则和事件 触发器, 通过网关控制和 QoS规则提供消息下发给 BBERF。
412、 S-GW或可信任非 3GPP接入网关安装新的 QoS规则和事件触发器, 然后向 vPCRF返回网关控制和 QoS规则提供确认消息;
413、 S-GW或可信任非 3GPP接入网关返回建立网关控制会话应答消息。
如上一实施例建立 IP-CAN会话后,由于 BBERF发生切换而发起 IP-CAN 会话修改, 如图 5所示, 各步骤描述如下:
12 180800477 501、 驻留有 BBERF的目的 S-GW或可信任非 3GPP接入网关收到建立 网关控制会话请求消息。 当通过 E-UTRAN接入时, 该消息为 MME发送的 默认承载建立请求消息, 当通过可信任非 3GPP接入网关接入时, 该消息为 可信任非 3GPP接入网中的层 3附着消息。 消息中携带用户标识和用户要接 入的 PDN的标识;
502、 驻留有 BBERF的目的 S-GW或可信任非 3GPP接入网关向 vPCRF 发送网关控制会话建立指示消息 (即 BBERF向 vPCRF发送网关控制会话消 息) , 消息中携带用户标识、 用户要接入的 PDN的标识以及 LBO指示, 。 vPCRF自身的网络 ID与上述消息中的 P-GW的网络 ID是相同的。 vPCRF根 据用户标识和用户要接入的 PDN 标识将该网关控制会话和之前建立的 IP-CAN会话进行关联;
503、 若之前 hPCRF下发的事件触发器中描述的事件发生 (如 UE的位 置发生了改变,接入技术类型发生了改变等), vPCRF向 hPCRF发送 IP-CAN 会话修改指示消息, 消息中携带指示事件变化的事件报告以及受影响的 PCC 规则;
vPCRF也可以不判断事件触发器中描述的事件是否发生, 只是将网关控 制会话消息中所携带的信息通过 IP-CAN会话修改指示消息发送给 hPCRF, 消息中除携带用户标识和用户要接入的 PDN的标识外, 还包含 UE的最新接 入信息如 UE的新的位置信息或接入技术类型等等。
504、 hPCRF根据事件报告的信息或者 UE的最新接入信息重新制定 PCC 规则, 并通过 IP-CAN会话修改确认消息发送给 vPCRF。 hPCRF也有可能更 新事件触发器, 并下发给 vPCRF;
若 hPCRF没有收到事件报告, 它根据 IP-CAN会话修改指示消息中携带 的信息, 如用户标识和用户要接入的 PDN的标识, 以及新的位置信息或接入 技术类型等重新制定 PCC规则, 并通过 IP-CAN会话修改确认消息发送给 vPCRF;
505、 vPCRF根据 PCC规则重新制定 QoS规则, 并通过网关控制会话建 立确认消息将 QoS规则发送给目的 S-GW或可信任非 3GPP接入网关。 目的 S-GW或可信任非 3GPP接入网关安装 QoS规则;
13 180800477 该步骤中, 如果 vPCRF还收到 hPCRF下发的更新后的事件触发器, 则 也要通过网关控制会话建立确认消息下发给目的 S-GW或可信任非 3GPP接 入网关, 目的 S-GW或可信任非 3GPP接入网关收到后需要安装该更新后的 事件触发器。
506、 目的 S-GW或可信任非 3GPP接入网关在接收到 501步中的建立网 关控制会话请求消息后向 P-GW发送建立 IP-CAN会话请求消息, 消息中携 带用户标识和用户要接入的 PDN的标识;
该步骤及后续相关步骤与步骤 502及后续相关步骤可以并行, 没有固定 的先后顺序。
507、 驻留有 PCEF的 P-GW向 vPCRF发送 IP-CAN会话修改指示消息;
P-GW根据收到的建立 IP-CAN会话请求消息中的用户标识和用户要接 入的 PDN的标识判断该 IP-CAN会话已存在时 ,向 vPCRF发送 IP-CAN会话 修改指示, 消息中携带用户标识和用户要接入的 PDN的标识。
508、 vPCRF 若判断有 hPCRF 下发的事件触发器中描述的事件发生, vPCRF向 hPCRF发送 IP-CAN会话修改指示消息, 消息中携带指示事件变化 的事件报告以及受影响的 PCC规则;
vPCRF也可以不判断事件触发器中描述的事件是否发生, 只是将 P-GW 发送的 IP-CAN会话修改消息中所携带的信息发送给 hPCRF, 其中包含 UE 的最新接入信息。
509、 hPCRF收到 IP-CAN会话修改指示消息后, 根据事件报告的信息或 者 UE的最新接入信息重新制定 PCC规则, 并通过 IP-CAN会话修改确认消 息发送给 vPCRF。 hPCRF也有可能更新事件触发器, 并下发给 vPCRF;
510、 vPCRF通过 IP-CAN会话修改确认消息向 P-GW发送 PCC规则, vPCRF规则可能会根据本地策略对 hPCRF下发的 PCC规则进行修改;
511、 P-GW安装 PCC规则, 并向目的 S-GW或可信任非 3GPP接入网关 发送建立 IP-CAN会话应答消息;
在步骤 510中, 如果 vPCRF还收到 hPCRF下发的更新后的事件触发器, 则也要通过上述 IP-CAN会话修改确认消息下发给 P-GW。 此时, 步骤 511
14 180800477 中 P-GW需要安装该更新后的事件触发器。
512、 vPCRF如判断步骤 509中下发的 PCC规则与步骤 504中下发的 PCC 规则相比发生了改变,则根据最新的 PCC规则重新制定 QoS规则,通过网关 控制和 QoS规则提供消息将更新后的 QoS规则下发给 S-GW或可信任非 3GPP接入网关;
该步骤中, 如果 vPCRF收到 hPCRF下发的更新后的事件触发器且与步 骤 505中下发的事件触发器不同, vPCRF还将该步骤收到的事件触发器下发 给 S-GW或可信任非 3GPP接入网关。
PCC规则的修改是可以多次的, 假设在 IP-CAN会话建立的时候下发了 PCC规则, 后来通过 IP-CAN会话修改下发新的 PCC规则, 因此 vPCRF需 要比较新下发的 PCC规则和上一次下发的 PCC规则, 在两者不同时保存新 下发的 PCC规则。
步骤 512是可选的。
513、 S-GW或可信任非 3GPP接入网关重新安装 QoS规则和事件触发器 (如果更新的话) , 并向 vPCRF返回网关控制和 QoS规则提供确认消息。
514、 目的 S-GW或可信任非 3GPP接入网关接收到步骤 511 中的建立 IP-CAN会话应答消息后, 向 P-GW返回建立网关控制会话应答消息;
515、 源 S-GW或可信任非 3GPP接入网关接收到删除网关控制会话请求 消息, 消息中携带用户标识和用户要接入的 PDN的标识;
516、 源 S-GW或可信任非 3GPP接入网关向 vPCRF发送网关控制会话 终结指示消息, 消息中携带用户标识和用户要接入的 PDN的标识;
517、 vPCRF根据用户标识和用户要接入的 PDN的标识将旧的网关控制 会话删除;
518、 源 S-GW或可信任非 3GPP接入网关将网关控制会话相关的 QoS 规则和事件触发器删除, 然后返回删除网关控制会话应答。
如第一个实施例建立 IP-CAN会话后, 由于用户请求新的资源或释放资 源发起 IP-CAN会话修改, 如图 6所示, 各步骤描述如下:
15 180800477 601、 驻留有 BBERF的 S-GW或可信任非 3GPP接入网关接收到网关控 制会话修改请求消息。 当通过 E-UTRAN接入时, 该消息为 MME发送的请 求承载资源分配或释放消息, 当通过可信任非 3GPP接入网关接入时, 该消 息为可信任非 3GPP接入网中特定的资源请求或释放消息;
602、 由于之前下发的事件触发器中定义的事件发生, 驻留有 BBERF的
S-GW或可信任非 3GPP接入网关向 vPCRF发送网关控制和 QoS规则请求消 息, 消息中携带指示事件变化的事件报告(如用户请求新的资源或释放资源) 以及受影响的 QoS规则;
603、 vPCRF向 hPCRF发送 IP-CAN会话修改指示, 消息中携带指示事 件变化的事件报告以及受影响的 PCC规则;
604、 hPCRF根据事件报告的信息, 重新制定 PCC规则, 并通过 IP-CAN 会话修改确认消息发送给 vPCRF。 hPCRF也有可能更新事件触发器, 并下发 给 vPCRF;
605、 vPCRF根据下发的 PCC规则重新制定 QoS规则, 并通过网关控制 和 QoS规则应答消息发送给 S-GW或可信任非 3GPP接入网关, 如果收到 hPCRF下发的更新后的事件触发器, vPCRF将更新后的事件触发器也一起下 发;
606、 S-GW或可信任非 3GPP接入网关安装新的 Qos规则, 如果收到更 新后的事件触发器则还需安装该事件触发器, 并向 vPCRF返回网关控制和 QoS规则应答确认消息;
607、 S-GW或可信任非 3GPP接入网关返回网关控制会话修改应答消息;
608、 vPCRF将步骤 604中下发的 PCC规则通过策略和计费规则提供消 息下发给 P-GW, 如果 hPCRF更新事件触发器的话, vPCRF将更新后的事件 触发器也一起下发给 P-GW;
609、 P-GW安装 vPCRF下发的 PCC规则, 如果收到更新后的事件触发 器则还需安装该事件触发器, 并向 vPCRF发送策略和计费规则提供确认。
如第一个实施例建立 IP-CAN会话后, 由于业务信息发生变化或用户签
16 180800477 约信息发生变化或网络策略发生变化等触发 PCRF发起 IP-CAN会话修改, 如图 7所示, 各步骤描述如下:
701、 可选地, AF将新的业务信息提供给 hPCRF;
这里, hPCRF也可以从其它网元获得新的用户签约信息或网络策略信息。 702、 hPCRF保存业务信息, 向 AF返回确认消息;
703、 hPCRF进行策略决策和授权, 重新制定 PCC规则。 hPCRF也有可 能会更新事件触发器;
704、 hPCRF将 PCC规则通过策略和计费规则提供消息发送给 vPCRF , 如果事件触发器更新, 将更新后的事件触发器同时下发 vPCRF;
705、 vPCRF根据下发的 PCC规则重新制定 QoS规则, 并通过网关控制 和 QoS规则提供消息将 QoS规则发送给 S-GW或可信任非 3GPP接入网关, 如果收到 hPCRF下发的更新后的事件触发器, vPCRF将更新后的事件触发器 也一起下发;
706、 S-GW或可信任非 3GPP接入网关安装新的 QoS规则, 如果收到更 新后的事件触发器则还需安装该事件触发器, 并返回网关控制和 QoS规则提 供确认消息;
707、 vPCRF将步骤 704中 hPCRF下发的 PCC规则通过策略和计费规则 提供消息发送给 P-GW,如果收到 hPCRF下发的更新后的事件触发器, vPCRF 将更新后的事件触发器也一起下发;
708、 P-GW安装 vPCRF下发的 PCC规则, 如果收到更新后的事件触发 器则还需安装该事件触发器, 并返回策略和计费规则提供确认消息;
709、 vPCRF向 hPCRF返回策略和计费规则提供确认消息。
需注意的是, 上述 vPCRF向 S-GW或可信任非 3GPP接入网关, 与向 P-GW下发 QoS规则的操作的先后顺序可以有不同设定, 本发明不局限于上 述实施例的顺序。
如第一个实施例建立 IP-CAN会话后,由于用户去附着而发起 IP-CAN会
17 180800477 话终结, 如图 8所示, 各步骤描述如下:
801、 驻留有 BBERF 的 S-GW或可信任非 3GPP接入网关接收到删除 IP-CAN会话的请求消息。 当通过 E-UTRAN接入时, 该消息为 MME发送的 删除承载请求消息, 当通过可信任非 3GPP接入网关接入时, 该消息为可信 任非 3GPP接入网中特定的去附着消息。 消息中携带用户标识和用户要接入 的 PDN的标识;
