Description

一种资源管理方法、 系统和资源管理网元
技术领域
本发明涉及通信领域, 具体涉及一种资源管理方法、 系统和资源管理网 元。 背景技术
第三代合作伙伴计划( 3rd Generation Partnership Project, 3 GPP )演进的 分组系统(Evolved Packet System, EPS ) , 如图 1所示的非漫游场景的 EPS 网络架构图, 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 ) 、 月良务网关 ( 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 ) 、 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。 策略与计费 规则功能实体(PCRF )是 PCC的核心, 负责策略决策和计费规则的制定。 PCRF提供了基于业务数据流的网络控制规则, 这些网络控制包括业务数据 流的检测、 门控( Gating Control ) 、 服务质量( Quality of Service , QoS )控 制以及基于数据流的计费规则等。 PCRF 将其制定的策略和计费规则发送给 PCEF执行, 同时, PCRF还需要保证这些规则和用户的签约信息一致。 PCRF 制定策略和计费规则的依据包括: 从 AF ( Application Function, 应用功能) 获取与业务相关的信息;从用户签约数据库( Subscription Profile Repository, SPR )获取与用户策略计费控制签约信息; 从 PCEF获取与承载相关网络的 信息。
EPS支持与非 3GPP系统的互通。 与非 3GPP系统的互通通过 S2a/b/c接 口实现, P-GW作为 3GPP与非 3GPP系统间的锚点。 EPS的系统架构如图 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接口与 P-GW连接, 该接口釆 用 PMIPv6 ( Proxy Mobile IP version 6, 代理移动 IP版本 6 )协议或者 GTP ( General Packet Radio Service tunnel Protocol, 通用分组无线月良务隧道协议 ) 协议;不可信任非 3GPP IP接入需经过 ePDG( Evolved Packet Data Gateway, 演进的分组数据网关) 与 P-GW相连, ePDG与 P-GW间的接口为 S2b, 釆 用 PMIPv6或者 GTP协议, 并且 UE ( User Equipment, 用户设备 )和 ePDG 之间釆用 IPSec ( Internet Protocol security, Internet协议安全性)对信令和数 据进行加密保护。 S2c提供了 UE与 P-GW之间的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 DSMIPv6 ( Mobile IPv6 Support for Dual Stack Hosts and Routers, 支持双栈的移动 IPv6 ) 。
当前课题 FMC ( Fixed Mobile Convergence, 固网移动融合 ) ,针对 3 GPP 和 BBF ( Broadband Forum, 宽带论坛)接入网策略统一管理进行研究。 所述 接入网一般称作固网, 特指无线局域网 (WLAN )接入。 FMC技术四种主要 的场景:
H(e)NB场景。 UE通过家庭基站( H(e)NB )接入核心网 EPC ( Evolved Packet Core, 演进的分组核心网) , 属于 3GPP/H(e)NB接入 EPC的技术的 场景,其中 H(e)NB占用了固网线路。业务数据流如图 2中的虚线(a )所示。
WLAN-EPC-routed场景。 UE通过 WLAN接入网(固网)接入移动核心 网 EPC, 该场景属于非 3GPP ( WLAN接入网 /固网 )接入 EPC的技术。 其 接入的基本准则需要符合上述 EPS支持与非 3GPP系统的互通的要求, 具体 又分为 S2a、 S2b和 S2c接入。 业务数据流如图 2中的虚线 (b)所示。
WLAN-NSWO(Non-seamless WLAN offload,非无缝的 WLAN分流)场景。
UE接入 WLAN接入网 (固网) , 通过 WLAN接入网 (固网) 的网关 BNG/BRAS(Broadband network Gateway/Broadband Remote Access Server, 宽带网络网关 /宽带远程接入服务器)直接拜访外部分组数据网络(PDN, Packet data network ) 。 业务数据流如图 2中的虚线 (c)所示。
固定设备 ( Fixed/BBF device )场景。 固定设备 (例如, 家庭电视, WLAN 的固定终端, 路由型的 RG(Residential Gateway , 家庭网关)等)接入 WLAN 接入网 (固网) , 通过 WLAN接入网 (固网) 的网关 BNG/BRAS直接拜访 外部分组数据网络。 业务数据流如图 2中的虚线 (d)所示。
下面分别说明以上场景的主要特征以及在这两种场景下运行业务时存在 的问题。
一. H(e)NB场景介绍
EPS支持家庭基站 ( HeNB , Home eNodeB )的接入, HeNB是一种小型、 低功率的基站, 部署在家庭、 办公室及企业大楼等室内场所。 HeNB通常通 过租用的固网线路接入 EPS的核心网, 如图 2所示。 为了保障接入的安全, 核心网中引入安全网关( Security Gateway, SeGW )进行屏蔽, HeNB与 SeGW 之间的数据将釆用 IPSec ( IP Security, 因特网协议安全性 )进行封装。 HeNB 可以通过与 SeGW建立的 IPSec隧道直接连接到核心网的 MME和 S-GW, 也可以再通过 HeNB GW连接到 MME和 S-GW, 即 HeNB GW是个可选网 元。同时,为了实现对 HeNB进行管理,引入了网元家庭基站管理系统(Home eNodeB Management System, HeMS ) , 因为与本发明关系不大, 故架构图 中未示出。
此夕卜 ,通用移动通信系统( Universal Mobile Telecommunications System, UMTS )支持家庭基站 HNB ( Home NodeB )的接入。 类似于图 2及其描述。 不同的是, 使用服务通用分组无线业务支撑节点 (Serving General Packet Radio Service Support Node, SGSN )代替了 S-GW, 使用网关通用分组无线 业务支持节点 ( Gateway General Packet Radio Service Supporting Node, GGSN ) 代替了 P-GW。
由于 H(e)NB接入的固网线路的 QoS通常是受到 HeNB/HNB的拥有者与 固网运营商的签约限制的。 因此, 当 3GPP UE通过 HeNB/HNB接入 3GPP 核心网访问业务时,所需的 QoS不能超过固网运营商所能提供的固网线路的 签约的 QoS。 否则, UE访问业务的 QoS将得不到保障, 特别是保障比特率 ( Guaranteed Bitrate, GBR )的业务更是如此。 因此, 对于 3GPP网络和固网 来说, 需要一套统一的管控机制来实现用户 /连接 /业务的接纳控制。 举例来 说: 当有新的业务发起时, 只有在固网保证有足够的资源 /带宽的情况下, 兼 顾考虑移动网资源也充足的条件下, 才能接纳该业务; 否则, 就应该拒绝该 业务。
为了实现资源的统一控制管理, 当前的解决方案是通过在 BNG/BRAS 与 PCRF之间引入的 Gxd接口来管理固网线路的资源, 具体的做法是, 终端 UE从 H(e)NB接入, H(e)NB把所在固网线路的信息(一般是 H(e)NB本地地 址、端口号, 以及固网的 FQDN等)通过 EPC核心网发送给 PCRF, 由 PCRF 找到 BNG并建立 Gxd接口上的策略会话,并通过 Gxd接口来协商策略信息, 管理固网线路资源, 对业务进行接纳控制。
二、 WLAN-EPC-routed场景介绍
对于 WLAN-EPC-routed场景, 类似于 H(e)NB场景, 也存在资源管理的 机制, 同样也存在资源不足导致业务操作失败的情况。 当前实现资源的统一 控制管理的具体做法是, 终端 UE从 WLAN接入 EPC, 接入过程中, 把终端 UE所在的固网线路信息 (一般是 UE本地地址、 IPsec端口号等)通过 EPC 核心网发送给 PCRF , 由 PCRF找到 BNG并建立 Gxd接口上的策略会话,并 通过 Gxd接口来协商策略信息, 管理固网线路资源, 对业务进行接纳控制。
三、 WLAN-NSWO场景介绍
对于 WLAN-NSWO场景, 终端 UE的接入也分为两种子场景: UE通过 固网接入认证的和 UE没有通过固网认证的。 无论哪种子场景也都存在资源 管理的机制, 同样也存在资源不足导致业务操作失败的情况。 当前对 UE通 过固网认证子场景下的资源的统一控制管理的具体做法是, 终端 UE 从 WLAN接入 , 因为 UE从固网中执行了认证 , 固网的 BNG/BRAS会感知 UE 的接入, BNG/BRAS会发起 Gxd接口上的策略会话的建立,通过该策略会话 来协商策略信息, 管理固网线路资源, 对业务进行接纳控制。 对于 UE没有 通过固网认证子场景下的资源的统一控制管理参见四。
四、 固定设备 ( Fixed/BBF device )场景
对于固定设备接入场景, 也分为几种子场景: 固定设备通过固网接入认 证, 固定设备没有通过固网认证的, RG场景。 无论哪种子场景也都存在资 源管理的机制, 同样也存在资源不足导致业务操作失败的情况。
首先对 RG场景, 当 RG工作在路由模式下时, RG上电是会执行接入认 证, 固网的 BNG/BRAS会感知 RG的接入, BNG/BRAS会发起 Gxd接口上 的策略会话的建立, 通过该策略会话来协商策略信息, 管理固网线路资源, 对接入该 RG下的没有经过固网认证移动 UE和固定设备的业务进行接纳控 制。 对于通过固网接入认证的固定设备, 其资源的接纳控制类同于
WLAN-NSWO场景。
对于没有通过固网接入认证的固定设备, 该设备是接在 RG下的, 其资 源管理和业务接纳控制是通过 RG的资源管理和业务接纳控制机制完成的。
综上所述, 固网线路下,可以有多种设备接入,接入的模式又可能不同。 不同场景可能并行存在。固网的资源需要合理的分配。根据当前的协议规定, BNG不能执行资源的统一控制和管理, 而制定策略的 PCRF, 因为存在不同 的接入设备和接入场景, PCRF可能同时存在多个(比如 HeNB场景的 PCRF, WLAN-EPC-routed的 PCRF可能不是同一个), 多个 PCRF控制该线路的资 源, 会出现重复计算(就是同一份资源可能同时分给不同的设备) 的问题从 而导致出错。 发明内容

下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
本发明实施例提供一种资源管理方法, 包括:
BNG/BRAS将 PCRF制定的策略发送给资源管理网元请求授权; 所述资源管理网元执行策略授权,将授权的策略发送给所述 BNG/BRAS 或者发送拒绝策略的消息给所述 BNG/BRAS。
其中,所述 BNG/BRAS收到所述授权的策略后,执行所述授权的策略或 者转发给所述 PCRF。
方案一
所述 PCRF制定的策略是为如下业务之一或其组合制定的策略: 移动终端通过家庭基站接入开展的业务;
移动终端通过无线局域网接入核心网开展的业务;
移动终端非无缝的无线局域网分流 NSWO业务;
接入 BBF网络的固网设备的业务;
工作于路由模式的家庭网关下的业务。
其中, 所述资源管理网元执行策略授权包括:
所述资源管理网元根据固网线路资源授权或者拒绝所述策略。
方案二
业务分为指定的第一类业务和第二类业务, 其中, BNG/BRAS将 PCRF 为第一类业务制定的策略发送给资源管理网元请求授权;
对第二类业务, 由资源管理网元制定策略, 包括: 所述资源管理网元接 收到 AF/TDF ( Traffic Detection Function , 业务检测功能 )发送的指定的第二 类业务的业务信息或者所述 BNG/BRAS发送的为所述第二类业务请求策略 的消息后, 为所述第二类业务制定策略后发送给所述 BNG/BRAS。

其中, 所述资源管理网元为所述第二类业务制定策略包括:
所述资源管理网元根据固网线路资源为所述第二类业务制定策略。
其中, BNG/BRAS和资源管理网元之间的交互基于状态会话方式,或者, 无^ 态会话方式。
下面通过实施例进一步说明本发明。 下述实施例中, 资源管理网元使用 PCRF+表示, 但本发明不限于此。
本架构实例用于诠释新网元 PCRF+和新接口 Xy, 如图 4-6分别阐述了 非漫游架构, 漫游家乡路由架构, 漫游-本地疏导架构。 PCRF+位于移动网络 域, 如果是漫游架构, 则位于拜访地的移动网络域, 通过 Xy 接口与 BNG/BRAS互通策略。
其中根据网元的功能不同还可以分为两种子方案选项:
方案一:
该方案中, 无论对于 UE从 H(e)NB或者 WLAN接入并建立 EPC-routed PDN连接建立场景, 还是 WLAN-NSWO UE接入、 固定设备接入, RG上电 场景, 都会有各自的 PCRF, 因此当多种不同的接入同时存在时, PCRF会存 在多个。 所有业务的策略均是由选定的 PCRF 为其制定。 制定的策略通过 BNG/BRAS 转发给 PCRF+请求授权, PCRF+根据固网线路资源等信息决定 是否授权该策略,并把授权的策略发给 BNG/BRAS, BNG/BRAS根据授权的 策略执行。也就是说, BNG/BRAS可以与多个 PCRF建立 Gxd接口上的策略 会话, PCRF的功能与现有技术相同, PCRF制定策略不考虑固网线路资源。 PCRF+不执行制定策略的功能, 仅仅只是策略授权功能。
网元 PCRF+, 具备以下功能和属性:
PCRF+位于拜访地移动网路域; 支持与 BNG /BRAS的策略接口 Xy;
PCRF+接受 BNG/BRAS发送来的策略授权请求, 并根据固网线路资源 执行策略授权, 并将授权结果反馈给 BNG/BRAS。
BNG/BRAS具备以下功能:
BNG/BRAS支持策略接口 Xy;
BNG/BRAS根据来自 PCRF的策略, 向给 PCRF+请求策略授权,执行授 权策略或者将策略授权结果转发给 PCRF。
方案二:
该方案中,对于 UE从 H(e)NB或者 WLAN接入并建立 EPC-routed PDN 连接建立场景, 由 EPC网络网关 ( S-GW或者 eDPG或者 P-GW ) 为其选择 PCRF ,因此在同一时间内可能存在多个 PCRF ,其策略都是由其对应的 PCRF 制定, PCRF制定策略不考虑固网线路资源情况; 对于 WLAN-NSWO UE接 入、 固定设备接入, RG上电场景, BNG/BRAS保证为其统一固网线路上的 业务选择统一的 PCRF+。
PCRF+具有双重功能: 制定策略(同现有的 PCRF )和授权策略。
第一重功能: PCRF+为第一类业务授权由 PCRF制定的策略。 具体操作 是 PCRF将制定的策略发送给 BNG/BRAS, 再由 BNG/BRAS转发给 PCRF+ 请求授权, PCRF+根据固网线路资源执行策略授权并反馈授权结果, BNG/BRAS执行授权结果或者将授权结果发送给 PCRF。
第二重功能: PCRF+为第二类业务制定策略并授权, 也可以称作制定授 权的策略, 具体操作是 PCRF直接根据固网线路资源制定授权的策略并发送 给 BNG/BRAS用于执行。
网元 PCRF+, 具备以下功能和属性:
PCRF+位于拜访地移动网路域;
支持与 BNG/BRAS的策略接口 Xy;
接收 BNG/BRAS发送的策略授权请求, 并根据固网线路资源授权策略, 并将授权结果反馈给 BNG/BRAS;
接收 AF/TDF发送来的业务信息或者 BNG/BRAS发送的策略请求,根据 固网线路资源制定授权策略并推送给 BNG/BRAS。
BNG/BRAS具备以下功能:
BNG/BRAS支持策略接口 Xy;
BNG/BRAS为第一类业务,根据来自 PCRF的策略, 向给 PCRF+请求策 略授权;
对于第二类业务, BNG/BRAS向 PCRF+请求授权策略, 根据 PCRF+授 权的策略执行。
其中, "PCRF+" 和 "Xy" 都是为新网元和新接口取的临时名称, 在标 准化或者制造产品时改用使用任何其他的名称均在本发明范围内。 Gxd接口 名称在后续标准工作或者产品实现时也可能更换名称,本发明对此不作限定。
漫游架构
参见图 3和图 4,分别对应漫游-家乡路由和漫游-本地疏导场景。 漫游场 景中, PCRF+在拜访网络域。 对应于上述的方案一, 因为 PCRF+只执行策略 授权功能,所以 PCRF+不支持漫游接口 S9;对应于方案二, PCRF+具有 PCRF 的制定策略的功能, 因此 PCRF+支持与家乡 hPCRF的漫游接口 S9, 并且从 hPCRF的角度来看, PCRF+扮演的就是拜访地 PCRF的功能。
方案一流程实例一
本实施例基于的是架构方案一, 场景是移动终端从 H(e)NB 系统接入, 或者从 WLAN系统接入, 为 EPC-routed业务建立 PDN连接的场景, 参见图
6。
步骤 601 -603. 3GPP UE从 H(e)NB系统接入,或者从 WLAN系统接入, 为 EPC-routed业务建立 PDN连接。
根据现有技术, S-GW和 PCRF之间建立了网关控制会话(在 S5/S8接 口釆用 PMIP协议时); P-GW和 PCRF之间建立了 Gx会话。 用于定位固网 网元和线路的隧道信息(即, HeNB本地地址及端口号(若端口号存在 ) , BBF 网络的 FQDN等)都已经通过网关控制会话或者 Gx会话发送到了 PCRF。
步骤 604. 受到步骤 602或者 603的触发, PCRF与 BNG/BRAS执行在 Gxd接口上的信令交互, 并把该移动终端的相关信息 (例如签约 QoS信息, 隧道信息等)发送给 BNG/BRAS; 其中, PCRF根据步骤 602和步骤 603所 获取的隧道信息找到 BNG/BRAS。
步骤 605. 受到步骤 604的触发, BNG/BRAS发起与 PCRF+的 Xy接口 上信令交互, 并把该移动终端的相关信息(例如签约 QoS信息, 隧道信息或 者隧道信息所对应的固网线路的 ID等)发送给 PCRF+。
其中, 步骤 604和步骤 605可以有两种实现方式:
方式一: 有状态会话方式。 也就是, Gxd接口上和 Xy接口上存在有状 态的会话。 执行 604和 605是建立 /修改该会话, 通过建立 /修改该会话, 传 递特定移动终端的相关信息。 而且该会话可以是为单个移动终端服务的, 也 可以是为多个移动终端服务的。举例来说, Gxd接口上在步骤 604执行的 "网 关控制会话建立 /修改"操作, 在步骤 605, BNG/BRAS作为 proxy (代理 ) , 把 Gxd接口上的 "网关控制会话建立 /修改"转发给 PCRF+。
方式二: 无状态会话方式。 也就是说, Gxd和 Xy接口上只有信令交互 而没有状态会话。 每次信令交互必须携带足够的终端相关的信息, 用于区分 该消息传递的信息是为该特定终端的。
当然, 对于 Gxd接口和 Xy接口, 其中一个接口釆用状态会话方式另外 一个接口釆用无状态会话方式, 也是可以的。
方案一流程实例二
本实施例基于架构方案一, 场景是 WLAN-NSWO UE接入、 固定设备接 入, RG上电场景下的 Xy接口信令交互, 参见图 7。
本实施例包含了三种场景, 分别对应以下的三种终端设备和业务:
A. 移动终端 NSWO业务 B. 接入 BBF网络的固网设备的业务
C. 工作于路由模式的家庭网关下的业务
步骤 701a. 对应于场景 A。 3 GPP UE从 WLAN接入建立 NSWO业务的 IP连接;
步骤 701b. 对应于场景 B。 固网设备从 WLAN接入建立本地 IP连接; 步骤 701c. 对应于场景 C。 路由模式的 RG上电, 建立本地 IP连接 步骤 702. BNG/BRAS检测到以上任一设备的接入, 与其选择的 PCRF 执行 Gxd接口上的信令交互, 并获取或者传递该对应设备的相关信息(例如 签约 QoS信息, 设备的本地地址信息或者固网线路 ID等) 。 Gxd接口上的 信令交互也有两种实现方式: 有状态会话方式和无状态会话方式, 机制同步 骤 604的描述。举例来说,对于有状态会话方式时, Gxd接口上建立 IP-CAN 会话。
步骤 703. BNG/BRAS发起与 PCRF+的 Xy接口上信令交互,并把该移动 终端的相关信息(例如签约 QoS信息,设备的本地地址信息或者固网线路 ID 等)发送给 PCRF+。 其中, Xy接口上的信令交互也可以釆用有状态会话或 者无状态会话两种方式。 举例来说, 如果 Xy接口上釆用有状态的会话模式 时, 当 BNG/BRAS检测到有设备接入时, 则发起 Xy接口上的会话建立。
方案一流程实例三
本实施例基于架构方案一,用于诠释策略授权的。分为三种场景 ΑΙ, ΒΙ ,
C1 , 参见图 8。
场景 A1 : 适用于以下业务
移动终端通过 H(e)NB接入开展的业务;
移动终端通过 WLAN接入 EPC开展的业务;
流程描述:
步骤 801a: 移动终端在 EPC网络发起承载操作 (比如承载建立 /修改 /删 除),或者网络侧针对某一移动终端的业务信息(比如, TDF/AF下发到 PCRF 的业务信息)到达 PCRF, PCRF制定策略。
步骤 802a: PCRF通过 Gxd接口向 BNG/BRAS发送策略授权请求。 举 例来说, PCRF发送 "网关控制和策略提供" 消息给 BNG/BRAS, 用于请求 策略授权。
步骤 803a: BNG/BRAS与 PCRF+执行策略交互, BNG/BRAS发送策略 授权请求给 PCRF+, PCRF+根据固网线路资源执行策略授权, 并将授权策略 反馈给 BNG/BRAS。举例来说, BNG/BRAS转发来自 PCRF的 "网关控制和 策略提供" 消息给 PCRF+, 用于请求策略授权。 PCRF+制定授权策略发送过 "网关控制和策略提供应答" 消息给 BNG/BRAS。
所述的策略授权, 也称为对业务的接纳控制。 举例来说, 如果固网线路 资源足够, PCRF+对某个业务的策略进行了成功授权, 那么表示批准了该策 略, 即允许该业务创建, 也就是接纳了该业务。 反之, 如果固网线路资源不 足, PCRF+对某个业务的策略执行了拒绝, 也就是没有接纳该业务。 后面提 到的策略授权和接纳控制均是这个含义。
策略授权过程可以按照如下方式执行:
根据步骤 605、 702携带的信息 (Xy接口釆用有状态会话模式时) , 或 者步骤 803a携带的信息 (Xy接口釆用无状态会话模式时) , PCRF+根据固 网线路 ID, 或者隧道信息, 或者是设备的本地地址信息判断当前有多少设备 的业务运行在当前的固网线路上, 并能计算当前固网线路上还有多少空余资 源 ,是否能满足步骤 803a请求授权的资源 ,根据计算结果,做最后授权决策, 并反馈给 BNG/BRAS。
当然, 复杂的策略授权可能不仅如此, PCRF+还可以根据用户级别、 业 务级别等特性对请求授权的资源做抢占、 或者根据优先级排队等处理。
步骤 804a: BNG/BRAS转发授权的策略给 PCRF。举例来说, BNG/BRAS 通过 Gxd接口向 PCRF发送 "网关控制和策略提供应答" 消息, 用于反馈策 略授权结果, 后续 PCRF在 EPC网络根据授权结果展开相关的操作。
说明, 以上 Gxd接口上的交互和 Xy接口上的交互, 如果在方案一流程 实例一和二中, 釆用的是有状态的会话模式, 即: Gxd接口上和 Xy接口上 是有策略会话的, 步骤 802a和 803a所述的信令交互可以通过 "修改 /更新" 会话携带要请求授权的策略实现, 因此在会话建 605和 702建立会话 /修改会 话的时候就已经判定了哪些会话是在同一个固网线路上的, 所以步骤 803a 只需要做策略授权就可以。 如果在方案一流程实例一和二中釆用的是无状态 的会话模式, 步骤 802a和 803a除了需要携带请求授权的策略外, 还要携带 能够标识固网线路的标识(比如隧道信息和固网线路 ID等) , PCRF+首先 判定请求的资源是否是在同一个固网线路上的, 然后再做策略授权。
场景 B1 : 适用于以下业务:
接入 BBF网络的固网设备的业务;
移动终端 NSWO业务;
工作于路由模式的家庭网关下的业务。
流程描述:
步骤 801b: 服务于以上业务的 PCRF受到触发, 比如 AF或者 TDF有相 关的业务信息下发至 PCRF, PCRF制定策略。
步骤 802b: PCRF通过 Gxd接口向 BNG/BRAS发送策略。 举例来说,
PCRF 发送 "IP-CAN 会话修改" 消息给 BNG/BRAS , 用于推送策略。 BNG/BRAS向 PCRF回应响应消息。
步骤 803b: BNG/BRAS与 PCRF+执行策略交互, BNG/BRAS发送策 略授权请求给 PCRF+, PCRF+根据固网线路资源执行策略授权, 并将授权的 策略反馈给 BNG/BRAS。 PCRF+执行策略授权过程可以按照参见步骤 803a 的描述。
场景 C1 : 适用于以下业务
接入 BBF网络的固网设备的业务;
移动终端 NSWO业务;
工作于路由模式的家庭网关下的业务。
流程描述:
步骤 801c: 设备从 BBF网络发起资源请求或者 BBF网络资源调整等。 步骤 802c: BNG/BRAS与 PCRF执行策略交互, BNG/BRAS向 PCRF 请求策略, PCRF为业务制定策略,并将策略发送给 BNG/BRAS。举例来说, BNG/BRAS发起 Gxd接口上的 IPCAN会话修改操作, 从 PCRF获取策略。
步骤 803c: BNG/BRAS将从 PCRF获取的策略发送给 PCRF+请求授权, PCRF+根据
参见 803a 描述的授权机制为策略执行授权, 并将授权结果反馈给 BNG/BRAS用于执行。
方案二流程实例一
本实施例基于的是架构方案二, 场景是移动终端从 H(e)NB 系统接入, 或者从 WLAN系统接入, 为 EPC-routed业务建立 PDN连接的场景, 参见图

接入 BBF网络的固网设备的业务;
工作于路由模式的家庭网关下的业务。
步骤 1001a-步骤 1001c. 同步骤 701a-步骤 701c
步骤 1002. 对于架构方案二的描述, 该 PCRF+有两种功能: 策略制定和 策略授权。也就是说该步骤的 PCRF+集成了图 7中的 PCRF+和 PCRF的双重 功能。因此该步骤中 Xy接口上的信令交互也集结成了图 7中 Gxd接口和 Xy 接口上信令的双重功能。
Xy接口上的信 举例来说, 如果 Xy接口上釆用有状态的会话模式时, 当 BNG/BRAS检测到 有设备接入时, 则发起 Xy接口上的会话建立。
方案二流程实例三

场景 A2: 适用于以下业务:

步骤 1102b: PCRF+通过 Xy接口向 BNG/BRAS推送授权的策略。 举例 来说, PCRF+发送 "IP-CAN会话修改" 消息给 BNG/BRAS, 用于推送已经 授权的策略。 BNG/BRAS向 PCRF+回应响应消息。
