Description

确定策略和计费规则功能实体的方法、 装置和*** 技术领域
本发明实施例涉及通信技术领域,尤其涉及一种确定策略和计费规则功 能实体的方法、 装置和***。 背景技术
Diameter协议是 3G网络的 PCC ( Policy and Charging Control, 策略和 计费控制 ) 架构以及 LTE ( Long Term Evolution, 长期演进) 、 IMS ( IP Multimedia Subsystem , IP 多媒体子***) 网络中广泛应用的协议。 DRA ( Diameter Routing Agent, Diameter消息路由代理)用于提供 Diameter信令 的消息路由功能, 通过部署 DRA组成下一代的信令网络。 DRA可以实现多 网络架构中 Diameter信令的集中转发,其中包括 GPRS( General Packet Radio Service, 通用分组无线业务)或 EPC ( Evolution Packet Core, 演进的包交换 核心网) 、 PCC网络中用户的移动性管理、 计费策略和计费信息等。
在 PCC***内, PCEF ( Policy and Charging Enforcement Function, 策略 和计费执行功能实体)通过 DRA路由到 PCRF ( Policy and Charging Rule Function, 策略和计费规则功能实体) , AF ( Application Function, 应用功 能实体 )也通过 DRA路由到 PCRF。 具体的, 对于 PCEF到 PCRF的路由, DRA采用用户的 IMSI ( International Mobile Subscriber Identification Number, 国际移动用户识别码)进行路由分析; 对于 AF到 PCRF的路由, 由于 AF 发送的路由请求中没有用户的 IMSI, 所以 DRA采用用户的 IP地址进行路 由分析。 为了保证同一个用户从 AF和 PCEF能路由到相同的 PCRF , DRA 中就需要记录同一个用户的 IP地址和 IMSI的对应关系。
为了提高信令网组网的可靠性, 可以进行双平面组网, 也就是使用两个 以上 DRA,其中一个或多个 DRA作为另一个 DRA的备份或者多个 DRA负 荷分担, 使得当其中一个 DRA发生故障时, 信令业务可以不受影响。 然而 现有技术只给出了单平面组网时 DRA确定 PCRF的方法, 由此双平面组网 场景下的 DRA确定 PCRF的方案是急需解决的技术问题。 发明内容
本发明实施例提供一种确定 PCRF的方法、 装置和***, 用以在双平面 组网场景下, 将同一用户的会话路由到相同的 PCRF。

为了更清楚地说明本发明实施例的技术方案, 下面将对实施例或现有技 术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面描述中的附图 仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造 性劳动的前提下, 还可以根据这些附图获得其他的附图。

图 2为本发明确定 PCRF的方法实施例二的流程图;
图 3为本发明确定 PCRF的方法实施例三的流程图;
图 4为本发明确定 PCRF的装置实施例的示意图;
图 5为本发明确定 PCRF的***实施例一的示意图; 图 6为本发明确定 PCRF的***实施例二的示意图;
图 7为本发明确定 PCRF的***实施例三的示意图。 具体实施方式
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。
图 1为本发明确定 PCRF的方法实施例一的流程图, 如图 1所示, 该方 法包括:
5101 ,第一 PCRF接收第一路由代理设备发送的携带用户的 IP ( Internet Protocol )地址的第一请求消息。
GPRS、 LTE等网络。 以下本发明各实施例中, 路由代理设备以 DRA为例进 行。
5102, 第一 PCRF根据所述用户的 IP地址来查询预先存储的用户 IP地 址和当前为用户服务的 PCRF标识的对应关系, 确定当前为所述用户服务的 第二 PCRF的标识。
其中, 这里的 PCRF标识可以是 PCRF的主机标识; 也可以是 PCRF的 IP地址和端口号; 也可以是 PCRF 的编号, 这里的编号可以是在网络中的 PCRF之间 (包括第一 PCRF和第二 PCRF )预先配置好的, 比如编号 1代 表 PCRF1, 编号 2代表 PCRF2, 各个 PCRF (包括第一 PCRF和第二 PCRF ) 一看到编号, 就知道代表编号所指示的 PCRF。 当然, PCRF 的标识也不限 于上述列举的几种情况。
S103 , 第一 PCRF将携带第二 PCRF的标识的消息发送给第一路由代理 设备, 以使第一路由代理设备根据所述第二 PCRF的标识将第一请求消息发 送到第二 PCRF。
其中, 这里第二 PCRF的标识可以是第二 PCRF的主机标识(也可以说 是主机名称), 也可以是第二 PCRF的 IP地址和端口号, 当然也不限于此。
可选的, 如果用户 IP地址和当前为用户服务的 PCRF标识的对应关系 是预先存储在 PCRF中, 那么 S102中, 第一 PCRF就查询自身预先存储的 用户 IP地址和当前为用户服务的 PCRF标识的对应关系。 本发明实施例中 用第一 PCRF代表不同于第二 PCRF的其他 PCRF。
如果用户 IP地址和当前为用户服务的 PCRF标识的对应关系是预先存 储在 SPR ( Subscription Profile Repository, 签约数据库 ) 中, 那么 S102中, 第一 PCRF就查询 SPR中预先存储的用户 IP地址和当前为用户服务的 PCRF 标识的对应关系。 其中, SPR是网络中多个 PCRF (包括第一 PCRF、 第二 PCRF )共享的数据库。 可选的, 第一 PCRF或 SPR还接收第二 PCRF发送 的所述用户的 IP地址和第二 PCRF的标识的对应关系;所述第一 PCRF或所 述 SPR将所述用户的 IP地址和所述第二 PCRF的标识的对应关系更新到所 述用户 IP地址和当前为用户服务的 PCRF标识的对应关系中。
对于用户 IP地址和当前为用户服务的 PCRF标识的对应关系预先存储 在 PCRF 中的方案, 如果网络中除了第二 PCRF外, 还有两个以上的其他 PCRF, 那么第二 PCRF将用户的 IP地址和第二 PCRF的标识的对应关系发 给其他 PCRF, 发送方式可以采用广播方式, 也可以采用依次发送, 具体的 发送方式这里不做限制。第二 PCRF和其他 PCRF将所述用户的 IP地址和所 述第二 PCRF的标识的对应关系更新到自身存储的用户 IP地址和当前为用 户服务的 PCRF标识的对应关系中。 。
本发明实施例通过将对应关系存储在 SPR或 PCRF 中, 可以充分利用 SPR或 PCRF的已有数据库, 对现有网络的设备不需要做大的投资, 保护现 有设备投资和降低网络维护成本。
可选的, 在第一 PCRF或 SPR接收第二 PCRF发送的所述用户的 IP地 址和第二 PCRF的标识的对应关系之前, 还包括: 所述第二路由代理设备接 收 PCEF发送的携带所述用户的用户标识和所述用户的 IP地址的第二请求消 息。 其中, 用户标识用于标识用户, 例如该用户标识可以为用户的 IMSI。
其中, 所述第二路由代理设备可以根据 PCEF发送的第二请求消息中携 带的用户的用户标识来确定第二 PCRF; 也可以根据算法来确定第二 PCRF。 然后,所述第二 PCRF将所述用户的 IP地址和所述第二 PCRF的标识的对应 关系发送给所述第一 PCRF或者所述 SPR。 这里所说的算法可以是第二路由 代理设备采用轮选的方法来确定第二 PCRF, 也可以是第二路由代理设备根 据每个 PCRF上分担的负荷比例来确定第二 PCRF。 其中, 第二路由代理设 备根据算法来确定为用户服务的 PCRF的方法, 相对于根据用户的 IMSI进 行静态配置来确定 PCRF的方法来说,可以达到对 PCRF上的负荷进行动态 负荷分担的效果。
可选的, 如果对于不同的用户, 网络有可能分配了相同的 IP地址, 那 么相应的 PCRF或 SPR中存储的为用户 IP地址、 网络标识和当前为用户服 务的 PCRF标识三者之间的对应关系。 其中, 网络标识是第一 PCRF从所述 第一请求消息中获取的。 相应的, 第一请求消息中还携带网络标识, 比如 APN ( Access Point Name,接入点名称)。 第一 PCRF接收到携带网络标识和 用户的 IP地址的第一请求消息, 然后根据所述网络标识和用户的 IP地址来 查询存储的用户 IP地址、 网络标识和当前为用户服务的 PCRF标识三者之 间的对应关系,确定当前为用户服务的第二 PCRF的标识。相应的,第二 PCRF 从第二路由代理设备发送的第二请求消息中获取用户的 IP地址和网络标识。 PCRF和路由代理设备之间具体的交互方法与对应关系为用户 IP地址和当前 述。
通过本发明实施例提供的确定 PCRF的方法, 可以将同一用户的会话路 由到相同的 PCRF,从而解决了双平面 DRA在多 PCRF组网情况下, 同一用 户的会话能路由到相同 PCRF的问题, 进一步提供了可靠的 DRA信令网组 网。
下面结合具体例子, 更加详细地描述本发明的实施例。 应注意, 图 2和 图 3的实施例只是为了帮助本领域技术人员更好地理解本发明, 而非要限制 本发明的范围。
图 2和图 3的实施例中, 以采用两个 DRA组网的 PCC网络为例来说明 本发明实施例的确定 PCRF方法。 本发明实施例对此不作限制, 本发明实施 例提供的方法还可以用在采用两个或多个 DRA组网的其他网络中, 例如 IMS、 GPRS或 LTE网络。 相应的 , 第一请求消息以 AF和 DRA接口之间的 Rx请求消息为例 ,第二请求消息以 PCEF和 DRA接口之间的 Gx请求消息 , 第一 PCRF和第二 PCRF分别以 PCRF2和 PCRF1 , 第一路由代理设备和第 二路由代理设备分别以 DRA2和 DRA1为例。
图 2是本发明确定 PCRF的方法实施例二的流程图。 S201-S205是存储 用户 IP地址和当前为用户服务的 PCRF标识对应关系的过程, S206-S211是 利用存储的对应关系来确定 PCRF的过程。
5201 , 端设备 PCEF在接收到用户发送的请求消息后, 向 DRA1发起 Gx Request消息, 用于建立 PCEF与 PCRF之间的 IP CAN ( IP Connectivity Access Network, IP连通接入网)会话。
其中, 该 Gx Request消息中携带用户的用户标识(比如: 用户的 IMSI ) 和用户的 IP地址, 该 IP地址为 PCEF在用户接入时为该用户动态分配的 IP 地址, 以使得该用户进行后续业务, 例如: 该用户通过 AF确定 PCRF时, 也使用该 IP地址。
5202 , DRA1接收到 PCEF发送的 Gx Request消息后, 确定为用户服务 的 PCRF为 PCRF1 , 然后将 Gx Request消息路由至 PCRF1。
其中,该 Gx Request消息中携带有用户的用户标识(比如:用户的 IMSI ) 和用户的 IP地址。 当然, 也可以如现有技术来携带 PCEF的信息, 这里不再 赘述。
具体的, DRA1 可以通过下面两种方法中的一种来确定为用户服务的 PCRF为 PCRF1 :
第一种, DRA1根据 Gx Request消息中携带的用户标识确定 PCRF 1。 第二种, 也可以根据算法来确定 PCRF1。 这里所说的算法可以是 DRA1 采用轮选 PCRF的方法来确定 PCRFl ,也可以是根据每个 PCRF上分担的负 荷比例来确定 PCRF1。 DRA1根据算法来确定 PCRF的方法, 相对于根据用 户的 IMSI进行静态配置来确定为用户服务的 PCRF来说,可以达到对 PCRF 上的负荷进行动态负荷分担的效果。
S203 , PCRF1接收 DRA1发送的 Gx Request消息后, 存储用户的 IP地 址和当前为用户服务的 PCRF1 标识的对应关系, 并将该对应关系发送给 PCRF2 , 以使 PCRF2存储该对应关系。
其中, PCRF1存储对应关系, 和将对应关系发送给 PCRF2这两个动作 无先后顺序之分。
可选的, 如果 PCRF (包括 PCRFl , PCRF2 ) 中已经存储了多个用户 IP 地址和为用户服务的 PCRF标识的对应关系, 那么 S203中, PCRF存储用户 的 IP地址和当前为用户服务的 PCRF1标识的对应关系, 也可以认为是将用 户的 IP地址和当前为该用户服务的 PCRF1标识的对应关系更新到已经存储 的用户 IP地址和为用户月良务的 PCRF标识的对应关系中。
可选的, 如果对于不同的用户分配了相同的 IP地址, 那么 Gx Request 消息中还携带网络标识, 比如 APN。 相应的, 存储的为用户 IP地址、 网络 标识和当前为用户月良务的 PCRF标识三者之间的对应关系。
如果网络中有多个 PCRF, 例如除了 PCRFl、 PCRF2之外, 还有其他的 PCRF,那么 PCRF1也会将该对应关系发送给其他的 PCRF,以使其他的 PCRF 也存储该对应关系。 这样, 如果后续该用户的会话被 DRA路由到其他的 PCRF上时, 其他的 PCRF可以根据存储的该对应关系来为确定为用户服务 的 PCRF。
5204 , PCRF 1发送 Answer消息给 DRA1。
5205 , DRA1发送 Answer消息给 PCEF。
5206, 该用户通过端设备 AF发起会话时, AF发送携带该用户的 IP地 址的 Rx Request消息给 DRA2 , 用于建立 AF与 PCRF之间的 IP CAN会话。
5207, DRA2确定将 Rx Request消息待路由到的 PCRF为 PCRF2, 然后 将 Rx Request消息路由至 PCRF2。
其中, Rx Request消息中携带用户的 IP地址, 当然也可以如现有技术来 携带 AF的信息, 这里不再赘述。
可选的, DRA2 可以根据算法来确定 PCRF2。 这里所说的算法可以是
DRA2采用轮选 PCRF的方法来确定 PCRF2, 也可以是根据每个 PCRF上分 担的负荷比例来确定 PCRF2。
5208 , PCRF2根据 Rx Request消息中携带的用户的 IP地址来查询用户 IP地址和当前为用户月良务的 PCRF标识的对应关系,来确定当前为该用户月良 务的 PCRF1的标识。
可选的, 如果 PCRF中存储的为用户 IP地址、 网络标识和当前为用户 服务的 PCRF标识三者之间的对应关系, 那么 PCRF2接收到携带网络标识 和用户 IP地址的 Rx Request消息 , 然后根据网络标识和用户 IP地址来查询 存储的用户 IP地址、 网络标识和当前为用户服务的 PCRF标识三者之间的 对应关系, 来确定 PCRF 1。
5209 , PCRF2发送 Answer消息到 DRA2 , 该 Answer消息中携带将 Rx Request消息重定向到 PCRF1的指示,用以指示 DRA2将 Rx Request消息重 定向到 PCRF1。
具 体 的 , Answer 消 息 中 可 以 携 带 Result-Code= DIAMETER— REDIRECT— INDICATION , Redirect-Host=PCRFl 。 DIAMETER REDIRECT INDICATION是重定向指示, Redirect-Host=PCRFl 是用来指示重定向到的目标 PCRF为 PCRF1。
5210, DRA2将携带该用户的 IP地址的 Rx Request消息发送给 PCRF1。
5211 , PCRF 1发送 Answer消息给 DRA2。
5212, DRA2发送 Answer消息给 PCEF。
可选的, 在上述实施例之后, 还可以包括: 该用户发起会话结束消息来 触发删除各个 PCRF中存储的用户 IP地址和当前为用户服务的 PCRF1的标 识的对应关系的过程。具体为:当该用户发起会话结束消息时, PCEF向 DRA1 发送用于去激活 PCEF与 PCRF1之间的 IP CAN连接的会话结束消息; DRA1 向 PCRF1发送所述会话结束消息; PCRF1删除自身存储的用户的 IP地址和 当前为用户服务的 PCRF1的标识的对应关系, 并向其他的 PCRF发送消息, 以使其他 PCRF 也删除已经存储的的用户 IP 地址和当前为用户服务的 PCRF1的标识的对应关系。 从而可以同步各个 PCRF之间存储的对应关系。
通过本实施例提供的确定 PCRF的方法, 可以将同一用户的会话路由到 相同的 PCRF。从而解决了双平面 DRA在多 PCRF组网情况下, 同一用户的 会话能路由到相同 PCRF的问题, 进一步提供了可靠的 DRA信令网组网。
进一步的, 将用户 IP地址和当前为该用户服务的 PCRF标识的对应关 系存储在 PCRF中, 可以充分利用 PCRF的已有数据库, 对现有网络的设备 不需要做大的投资, 保护现有设备投资和降低网络维护成本。
进一步的, DRA在收到端设备发送的请求消息后, 根据轮选或每个 PCRF上分担的负荷比例来确定为用户服务的 PCRF, 并将请求消息路由到 进一步的, 当用户结束会话后,通过发起会话结束消息,从而使各 PCRF 删除已经存储的用户 IP地址与当前为该用户服务的 PCRF标识的对应关系, 即同步了各个 PCRF之间存储的对应关系, 又及时清除了 PCRF中的无用信 息。
图 3是本发明的确定 PCRF的方法实施例三的流程图。 S301-S305是存 储用户 IP地址和当前为用户服务的 PCRF标识对应关系的过程, S306-S314 是利用存储的对应关系来确定当前为用户服务的 PCRF的过程。 与图 2不同 的是, 在图 2中, 用户 IP地址和当前为用户服务的 PCRF标识的对应关系 是存储在网络中的 PCRF中的, 而在图 3中, 用户 IP地址和当前为用户服 务的 PCRF标识的对应关系是存储在 SPR中的。
S301-S302, 与 S201-S202相同, 这里不再赘述。
S303 , PCRF1接收 DRA1发送的 Gx Request消息后, 将用户 IP地址和 当前为用户服务的 PCRF1的标识的对应关系发送给 SPR。
由于 SPR是网络中多个 PCRF可以共享的数据库,因此将对应关系存储 在 SPR中, 网络中的 PCRF都可以去查询并获取该对应关系。
S304-S307, 与 S204-S207相同, 这里不再赘述。
5308, PCRF2向 SPR发送携带用户 IP地址的查询请求消息。
5309, SPR根据所述用户的 IP地址来查询存储的用户 IP地址和当前为 用户服务的 PCRF标识的对应关系, 来确定当前为该用户服务的 PCRF1的 标识。
5310, SPR确定 PCRF1后, 向 PCRF2发送将携带有 PCRF1标识的查 询响应消息。
S311-S314, 与 S209-S212相同, 这里不再赘述。
可选的, 如果 SPR中存储的为用户 IP地址、 网络标识和当前为用户服 务的 PCRF标识三者之间的对应关系, 那么 PCRF2接收到携带网络标识和 用户 IP地址的 Rx Request消息 ,然后才 据网络标识和用户 IP地址去 SPR查 询存储的用户 IP地址、 网络标识和当前为用户服务的 PCRF标识三者之间 的对应关系, 来确定 PCRF 1。
可选的, 在上述实施例之后, 还可以包括: 该用户发起会话结束消息来 触发删除 SPR中存储的对应关系的过程。具体为: 当该用户发起会话结束消 息时, PCEF向 DRA1发送用于去激活 PCEF与 PCRF1之间的 IP CAN连接 的会话结束消息; DRA1向 PCRF1发送所述会话结束消息; PCRF1向 SPR 发送消息, 以使 SPR删除自身存储的用户的 IP 地址和当前为用户服务的 PCRF 1的标识的对应关系。
通过本实施例提供的确定 PCRF的方法, 可以将同一用户的会话路由到 相同的 PCRF。从而解决了双平面 DRA在多 PCRF组网情况下, 同一用户的 会话信息能确定到相同 PCRF的问题, 进一步提供了可靠的 DRA信令网组 网。
进一步的, 将用户 IP地址和当前为用户服务的 PCRF标识的对应关系 存储在 SPR中, 可以充分利用 SPR的已有数据库, 对现有网络的设备不需 要做大的投资, 保护现有设备投资和降低网络维护成本。
进一步的, DRA1 在收到端设备发送的请求消息后, 根据轮选或每个 PCRF上分担的负荷比例来确定为用户服务的 PCRF, 并将请求消息路由到 为用户服务的 PCRF, 从而实现了对 PCRF上的负荷进行动态负荷分担的效 果。
进一步的, 当用户结束会话后, 通过发起会话结束消息, 从而使 SPR 删除已经存储的对应关系, 及时清除了 SPR中的无用信息。
