Description
在全业务融合网络中控制资源的方法和系统
技术领域
本发明涉及通信领域, 尤其涉及一种在全业务融合网络中控制资源的方 法和系统。
背景技术
如图 1所示, 3GPP提出的演进的分组系统( Evolved Packet System , 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, E-UTRAN ) 、 移动管理单元 ( Mobility Management Entity, MME ) 、 服务网关 ( Serving Gateway, S-GW ) 、 分组数据网络网关 ( Packet Data Network Gateway, P-GW或者 PDN GW)、 归属用户服务器 ( Home Subscriber Server, HSS ) 、 3 GPP的认证授权计费 (Authentication, Authorization and Accounting , AAA )服务器、策略和计费规则功能( Policy and Charging Rules Function, PCRF ) 实体及其他支撑节点组成。
在 EPS的系统中, 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是 EPS与分组数据网络( Packet Data Network, PDN )的边界网关, 负责 PDN的接入及在 EPS与 PDN间转发数据等; S-GW 和 P-GW都属于核心网网关; PCRF是策略和计费规则功能实体, 通过接口 Rx和运营商网络协议( Internet Protocol , IP )业务网络相连, 获取业务信息, 此外, 还通过 Gx/Gxa/Gxc接口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系统支持与非 3GPP系统的互通, 通过 S2a/S2b/S2c接口实现, 其中
EPS系统中的 P-GW作为 3GPP与非 3GPP系统间的锚点。 在 EPS的系统中, 非 3GPP接入被分为可信任非 3GPP IP接入和不可信任非 3GPP IP接入。
下面对非 3GPP系统接入 P-GW的方式进行说明:
可信任非 3GPP IP接入可直接通过 S2a接口与 P-GW连接; 不可信任非 3GPP IP接入需经过演进的分组数据网关 (Evolved Packet Data Gateway, ePDG )与 P-GW相连, 其中 ePDG与 P-GW间的接口为 S2b; 用户设备 ( User Equipment, UE )通过接口 S2c与 P-GW连接, 其中 S2c 可实现用户面相关的控制和移动性支持, 其支持的移动性管理协议为支持双 栈的移动 IPv6 ( Mobile IPv6 Support for Dual Stack Hosts and Routers , DSMIPv6)。
在 EPS系统中, PCRF通过如下接口与其他网元进行通信:
当策略和计费执行功能( Policy and Charging Enforcement Function, PCEF ) 实体驻留在 P-GW中, PCRF与 P-GW之间通过 Gx接口交换信息;
当 P-GW与 S-GW间的接口 ^^于 PMIPv6时, S-GW具有承载绑定和事 件才艮告功能( Bearer Binding and Event Report Function, BBERF ) 实体对业务 数据流进行 QoS控制的功能, PCRF通过 Gxc接口与 S-GW交换信息;
当用户通过驻留有 BBERF的可信任非 3GPP接入系统接入 EPS系统时, PCRF间通过 Gxa接口与可信任非 3GPP接入网关交换信息;
当 UE漫游时, 拜访地 PCRF和归属地 PCRF通过 S9接口进行通信, 同 时 PCRF通过 Rx接口从提供业务的应用功能( Application Function, AF )获 取用于制定 PCC策略的业务信息。
在 3GPP中, 通过接入点名称( Access Point Name, APN )可以找到对应 的 PDN网络。通常将 UE到 PDN网络的一个连接称为一个 IP连接接入网( IP Connectivity Access Network, IP-CAN )会话。 在建立 IP-CAN会话的过程中, BBERF和 PCEF分别与 PCRF之间建立 Diameter会话,通过这些 Diameter会 话来传送对 IP-CAN会话进行控制的策略计费信息和用于制定策略的业务信 息等。
在 EPS系统中, 以 PCRF为核心的策略和计费控制与执行等网元和功能 通常成为 PCC系统。在 PCC系统中, PCRF可以动态地下发 PCC策略给 PCEF , 该 PCC策略中包含 QoS和计费的信息。其中所述 PCC策略是 PCRF根据 AF 提供的业务相关信息、 PCEF上报的承载相关信息以及 SPR中用户签约的业
务信息制定的。 其中 PCC系统如图 2所示:
PCRF负责策略和计费规则的制定, 通过 Gx接口将制定的 PCC策略和 计费规则下发给 PCEF, PCEF安装、 执行 PCC策略, 并上报相关事件, 与计 费系统交互计费信息;
BBERF通过 Gxx接口从 PCRF接收业务的 QoS规则 , 不和计费系统交 互计费信息, 只负责承载绑定和相关事件的上报;
AF通过 Rx接口向 PCRF提供业务信息;
SPR保存用户签约的业务信息, PCRF可以通过 Sp接口向 SPR查询用户 签约的业务信息; PCEF通过 Gy接口将在线计费信息发送给在线计费系统( Online Charging
System , OSC ) , 以进行在线计费的统计, 通过 Gz接口将离线计费信息发 送给离线计费系统( Offline Charging System, OFCS ) 。
在 3GPP移动网络中, UE和 GW之间可以建立多条不同 QoS优先级的 承载。 通过将不同 QoS的业务流在对应 Qos优先级的承载上传输, 保证业务 的 QoS。 当 AF根据业务层协商的 QoS向 PCRF发起策略控制请求时, PCRF 会根据用户签约信息(从 SPR中获取 ) 以及运营商策略进行授权, 生成 PCC 策略, 下发给 GW中的 PCEF功能。 其中所述 PCC策略包括如下信息: 业务 流五元组、 QoS信息(如 QCI、 上下行带宽等)、 计费信息(如 Charging Key 等) 。 UE和 GW之间会根据业务的 QoS建立承载或者修改已有承载的 QoS 属性, 并在 UE侧执行上行业务流量的承载绑定, 即记录该业务流应该从哪 个承载传输; 在 GW侧执行下行业务流量的承载绑定, 并且对于上行流量打 相应的 QoS优先级标签(如 DSCP ) , 以保证上行流量在骨干网中的 QoS优 先级, 同时根据 PCC策略中的计费信息对业务流进行计费控制。
在 R8中, S-GW和 P-GW之间可以釆用 GTP或者 PMIP两种协议进行通 信。 当釆用 GTP协议时, 承载是建立在 UE和 P-GW之间, 因此, 只需要在 P-GW上通过 PCEF进行策略和计费控制; 当釆用 PMIP协议时, 承载是建立 在 UE和 S-GW之间, 因此需要在 S-GW上通过 BBERF功能进行承载绑定, 保证业务流在 S-GW到 UE之间的 QoS, 同时在 P-GW上通过 PCEF功能进
行 QoS和计费控制。
当前, 随着电信产业的并购和重组, 大部分运营商成为了既有固定网络 也有移动网络的全网络运营商。 固定网络和移动网络的融合以及全业务运营 成为各大运营商的重要发展方向。 全业务融合网络将以 IP承载为主, 能够提 供丰富的话音、 视频和数据等多媒体综合业务, 同时釆用开放、 标准的体系 结构, 为用户提供个性化、 移动化、 宽带化、 多媒体化服务, 因此实现对用 户资源及服务质量(Quality of Service, QoS )策略的统一部署和管理, 同时 保证单个用户 /业务的精细化控制和 QoS将是全业务运营发展的方向。
策略和计费控制 (Policy and Charging Control, PCC ) 系统处于网络的业 务控制层和承载层之间, 可以为业务层提供 QoS支持和计费控制, 是运营商 实现对业务精细化控制和 QoS保证的重要的运营支撑系统。
PCC 系统是针对第三代合作伙伴计划 ( 3rd Generation Partnership Project , 3GPP )的无线接入方式建立的。 对于全网络运营商来说, 用户的接 入方式还包括固网接入, 现有技术中没有一种基于 QoS策略统一对固定网络 和移动网络进行计费控制的方法, 从而不能基于业务的 QoS进行计费控制。
发明内容
本发明提供的在全业务融合网络中控制资源的方法和系统, 实现对固定 网络和移动网络统一的 QoS策略控制。
为达到上述发明目的, 本发明提供了如下技术方案:
一种在全业务融合网络中控制资源的方法, 包括:
资源控制功能(RCF )从策略和计费规则功能(PCRF )接收业务流的资 源请求消息; 以及,
所述 RCF根据所述资源请求消息进行资源分配。
上述方法中, RCF根据资源请求消息进行资源分配的步骤可包括: 判断 是否有足够可用的资源; 以及, 在确定可用资源充足时, 接纳业务流的资源 请求; 在确定可用资源不充足时, 拒绝业务流的资源请求。 该方法还可包括: PCRF在如下任一条件下发送业务流的资源请求消息: 授权应用功能(AF )
的策略请求之后; 服务质量策略发生变化时。 其中, 服务质量策略可以是在
PCRF受到内部或外部触发时发生变化,服务质量策略发生变化可以是指: 用 户的签约信息发生变化, 和 /或, 运营商配置发生变化。

图 2为现有技术中 PCC系统的结构示意图;
图 3为现有技术中固定网络的结构示意图;
图 4为本发明提供的 PCC系统的结构示意图;

本发明的较佳实施方式
下面结合附图对本发明实施例提供的技术方案作进一步介绍。
如图 3所示, 在固定网络中宽带接入网络(如 DSL ) 包括用户终端 UE (如 PC等)、接入节点 AN (如 DSLAM )和接入服务器 AS (如 BRAS、 BNG 等)。 AN通过多个起汇聚作用的以太交换机接入到 AS, AS上行接入城域网, 城域网上行会接入骨干网。 其中 AS是运营商开展业务的关键节点, AS与认 证服务器(AAA或 NASS )相连, 当 UE接入时, 将 UE的用户名密码发往 认证服务器进行认证, 并为 UE分配 IP地址。
与移动网络不同的是, UE和接入服务器之间并不会通过建立不同的承载 来区分不同的优先级业务流。 因此在固网实现基于业务的动态 QoS控制, 需 要一个网元能够维护网络拓朴以及资源状况, 为业务提供基于网络资源状况 的接纳控制, 并且确定策略执行点, 将 QoS策略分发给所确定的执行点, 为
便于描述,我们将该网元称为资源控制功能( Resource Control Function, RCF ) 实体。
如图 4所示,本发明提供一种固定移动融合的资源控制系统,在原有 PCC 系统的基础上增加 RCF实体, 用于维护固定网络的网络拓朴和网络的资源状 况。
在本发明提供的 PCC系统中, RCF通过如下方式与其他实体进行通信, 包括:
通过 R1接口从 PCRF实体获取策略以及资源请求;
通过 e4接口与认证服务器进行信息交互;
通过 R2接口将策略下发给策略执行功能 ( Policy Enforcement Function,
PEF ) 实体, 其中 PEF实体驻留在固网传输层网元上, 用于执行从 RCF接 收下发的策略。
下面结合具体组网图对本发明的方案进一步说明, 如附图 5所示: 固定网络用户终端通过家庭网关 ( Customer Network Gateway, CNG )接 入运营商网络, 连接到 AN实体(如 DSLAM等); AN实体通过接入网汇聚 层接入到宽带网络网关 ( Broadband Network Gateway, BNG ) 实体; BNG上 行接入到城域骨干网,其中城域骨干网中部署有运营商提供的 IP业务服务器。 需要说明的是, 如果运营商规模较小, BNG实体会接入到骨干网。
在本发明中, RCF与 PCRF相连, 既维护固网拓朴和资源状况, 为业务 的策略请求提供接纳控制, 同时根据业务的情况和传输层网元的实际能力, 向相应的传输层网元下发策略, 其中所述传输层网元包括如下网元的一种或 多种: CNG、 AN和 BNG。
下面结合附图对本发明提供的技术方案进行说明:
实施例一
本实施例以用户设备请求传输业务流的应用场景为例进行说明, 具体过 程如图 7所示:
步骤 601、 UE与 AF之间进行业务协商, 包括确定业务流的 QoS参数;
步骤 602、 AF根据协商好的 QoS参数向 PCRF发起策略控制;
步骤 603、 PCRF根据用户的业务签约信息以及运营商的策略, 和 AF发 来的请求消息中的业务信息制定策略, 其中所述业务签约信息是从 SPR获取 的, 其中所述策略包括 QoS策略和 /或计费策略;
步骤 604、 如果用户是从固网接入, PCRF将策略发送给 RCF;
步骤 605、 RCF收到策略后进行资源可用性检查, 即判断业务流经过的 路径上是否还有足够的可用资源, 如果有, 则接纳用户发起的资源请求, 并 执行步骤 606; 如果没有, 则拒绝所述资源请求, 流程结束;
步骤 606、 RCF向传输层网元下发策略;
步骤 607、 传输层网元执行所述策略, 根据策略内容对业务流进行管理, 包括标记 QoS优先级、 限制带宽等。
实施例二
本发明实施例以 Qos策略发生变化的常见应用为例进行说明, 具体过程 如图 7所示:
步骤 701、 在会话过程中, PCRF受到内部或外部的触发(例如: 用户的 签约信息发生变化; 运营商配置发生变化) , 对用户的 QoS策略进行修改; 步骤 702、 如果该用户是从固网接入的, PCRF通知 RCF更新后的 QoS 策略;
步骤 703、 RCF对资源更新进行资源可用性检查, 判断该用户的业务流 经过的路径上是否有足够的资源保证更新的执行, 如果有, 接纳更新请求, 并执行步骤 704; 若没有, 则拒绝所述资源更新请求, 流程结束。
步骤 704、 RCF向相应的传输层网元下发更新的策略, 其中所述策略包 括 QoS策略和 /或计费策略。
步骤 705、 传输层网元执行更新策略, 根据策略内容对业务流进行管理, 包括标记 QoS优先级, 限制带宽等。
下面以图 3所示固定网络为例进行说明:
RCF维护记录有网络拓朴与资源状况列表, 其中路径 al、 a2、 a3、 a4的
带宽上下行均为 10M, 路径 bl、 b2的上下行带宽为 15M。
固定网络中 UE1向城域网中某服务器发起一个需要 QoS保证的业务,需 要 10M上下行带宽; RCF进行资源可用性检查, 接纳了该资源请求, 为 UE1 分配路径 al ; 此时, RCF 中维护的拓朴与资源状况需要进行更新, 路径 al 剩余的上下行为 0M, 路径 bl剩余的上下行带宽为 5M。
进一步地, 为保证该业务的流量在经过的设备中能够优先被转发, 不会 受到其他流量的冲击。 RCF需要向其他网元下发 QoS策略, 其中在向 AN点 下发的 QoS策略中,对该业务流的上行流量打上高优先级 QoS标记; 在向城 域网中该服务器的出口路由器下发的 QoS策略中, 对该业务流的下行流量打 上高优先级 QoS标记。
进一步地, RCF还可以向 AN/AS点发送 UE1的计费策略, 由 AN/AS点 根据测量对该业务流进行计费信息统计。
如果该固定网络中 UE2再发起一个上下行带宽为 10M的需要 QoS保证 的业务, 此时, RCF根据本地维护的网络拓朴与资源状况列表, 确定路径 a2 上的可用带宽为 10M, 但是路径 bl上的剩余可用带宽只有 5M, 没有足够的 资源用于 UE2业务流的传输, 则 RCF拒绝 UE2的资源请求, 保证已接纳业 务流(即 UE1的业务流) 的传输不会受到冲击。
当检测到 UE1释放占用的带宽后, RCF更新本地维护的网络拓朴与资源 状况列表, 此次更新后路径 bl的可用带宽为 15M, 则 RCF接纳 UE2的资源 请求。

其中所述 PCF包括判断模块和处理模块。 所述判断模块判断所述业务流 经过的路径上可用资源是否充足; 在确定可用资源充足时, 所述处理模块接 纳所述业务流的资源请求, , 若可用资源不足, 则所述处理模块拒绝所述业 务流的资源请求。
本发明中所述业务流的资源请求是在授权 AF的策略请求后和 /或服务质 量策略发生变化后所述 PCRF发送的。 而所述服务质量策略发生变化是所述 PCRF在受到内部或外部触发时发生的, 包括以下变化的一种或多种: 用户的 签约信息发生变化, 运营商配置发生变化。
本发明的所述系统还包括认证服务器, 所述 RCF设置成通过如下方式中 的一种或多种与所述系统中除该 RCF之外的其他网元进行通信: 通过 R1接 口与所述 PCRF进行通信;
通过 R2接口与所述 PEF进行通信;
通过 e4接口与认证服务器进行通信。
