MME与 EUTRAN、 S-GW和家用基站网关 ( HeNB GW )相连接, 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。
EPS支持 HeNB的接入, HeNB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。 闭合用户组(Closed Subscriber Group, 简称为 CSG ) 是引入家用基站后提出的新概念。 通常一个家庭或者一个企业内部的用户组 成一个闭合用户组, 这个闭合用户组用 CSG ID进行标识。 为这个闭合用户 组内用户服务的家用基站具有相同的 CSG ID。当一个闭合用户组只由一个家 用基站服务时, 该闭合用户组也可以直接釆用家用基站标识(例如, BS ID ) 来进行标识。 根据家用基站管理者的意愿, CSG用户和 /或非 CSG用户可以 区分不同的等级, 优先级不同则其享受的业务优先级, 享受服务质量和业务 类别都可以不同。
用户通过与运营商签约可以接入到多个闭合用户组所对应的家用基站, 例如, 用户的办公场所、 家庭等。 因此引入了允许闭合用户组列表的概念。 这个列表保存在用户的终端和网络侧的用户数据服务器中。
家用基站的使用模式分为三种: 闭合模式、 混合模式和开放模式。 当家 用基站是闭合模式的时候,只有该家用基站所属 CSG签约用户可以接入该基 站并享受基站提供的业务。 当家用基站是开放模式的时候, 任何运营商签约 用户都可以接入该基站, 此时的家用基站等同于宏基站使用。 当家用基站是 混合模式的时候, 同样允许任何运营商签约用户或者漫游用户接入使用, 但 是要根据用户是否签约 CSG的信息区分不同的级别, 也就是说签约该 CSG 的用户在使用混合型家用基站的时候具有更高的业务优先级, 享受更好的服 务质量和业务类别。 当用户进行初始化接入的时候, 网络侧的用户数据服务器会把用户签约 的允许接入的闭合用户组发送到核心网的移动性管理实体。 核心网移动性管 理实体会利用这个信息对 UE进行接入控制。如果 UE从未授权的闭合模式家 用基站访问核心网, 那么核心网会拒绝该类用户的接入。
HeNB通常通过租用的固网线路(也称宽带接入 BBF( Broadband Access ) ) 接入 EPS的核心网。 为了保障接入的安全, 核心网中引入安全网关( Security Gateway, 简称为 SeGW )进行屏蔽, HeNB与 SeGW之间的数据将釆用 IPSec 进行封装。 HeNB可以通过 HeNB与 SeGW之间建立的 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在 EPS中是可选的) 。 同时, 为了实现对 HeNB进行管理, 引入了网元: 家用基站管理系统( Home eNodeB Management System, 简称为 HeMS ) 。
由于 HeNB接入的固网线路的 QoS (服务质量)通常是受到 HeNB的拥 有者与固网运营商的签约限制的。 因此, 当 3GPP UE通常 HeNB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, 特别是保障带宽 ( Guaranteed Bitrate, 简称为 GBR )。 因此, 对于 3GPP网络来说, 必须控制 通过 HeNB接入的所有 UE的业务访问的 QoS总需求不超过该 HeNB接入的 固网线路签约的 QoS保障。
此外, UE也可以通过 HNB接入 EPS。 此时, HNB与 HNB GW接口, 而 HNB GW与 SGSN接口, SGSN再与 S-GW接口。
此夕卜 , 通用移动通信系统 ( Universal Mobile Telecommunications System, 简称为 UMTS )也支持家用基站 HNB ( Home NodeB ) 的接入。 图 2是根据 相关技术的非漫游场景下的 HNB接入 UMTS的架构示意图。 图 2与图 1的 架构类似, 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, 简称为 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, 简称为 GGSN )代替了 P-GW。 在 UMTS中, HNB GW是必选的。 此 夕卜, UMTS系统中还支持电路交换(Circuit Switch, CS )业务, HNB GW与 移动交换中心 ( Mobile Switching Center, MSC ) 。
目前, 艮多运营商关注固网移动融合( FMC , Fixed Mobile Convergence ) , 并针对 3GPP和宽带论坛(BBF, Broadband Forum )互连互通进行研究。 对 于用户通过固定宽带接入网 (Fixed Broadband Access Network )接入移动核 心网的场景, 需要对数据的整个传输路径(数据会经过固网和移动网传输) 上的 QoS进行保证。 当前技术中, 通过 PCRF与固定宽带接入网中的宽带策 略控制架构 (BPCF, Broadband Policy Control Framework )进行交互, 实现 QoS保障。 BPCF为固定宽带接入网中的策略控制架构,对 PCRF的资源请求 消息, BPCF根据固定宽带接入网的网络策略、签约信息等进行资源接纳控制 或者将资源请求消息转发给其他 BBF接入网的网元(如 BNG ) , 再由其他网 元执行资源接纳控制 (即委托其他网元执行资源接纳控制) 。
在家用基站通过签约固定宽带接入网的线路接入的情况下, 必须考虑多 个家用基站(例如, HeNB、 HNB )通过一个签约固网线路接入 3GPP核心网 的场景。 这时, 对于 3GPP 网络来说, 必须控制通过这多个家用基站接入的 所有用户设备 ( User Equipment , 简称为 UE ) 的业务访问的 QoS总需求不超 过这多个家用基站接入的同一个固网线路的签约 QoS保障。
目前, 已经提出了一种用于家用基站接入策略控制的架构, 如图 3所示。
H(e)HB Policy Function (家用基站策略功能 )与 H(e)NB子系统接口, 并对家 用基站接入进行策略控制。 其中, H(e)NB Policy Funciton可以独立部署也可 以集成在 PCRF中。 然而, 现有技术只提供了一个粗略的架构, 如何进行策 略控制还是一个待解决的问题。 发明内容

图 4为本发明的架构图 1。 UE通过 HeNB接入 EPS的架构中存在 HeNB
GW。 H(e)NB Policy Function通过 Tl接口与 H(e)NB GW进行信息交互。
H(e)NB和 SeGW可以合设, 也可以分设。 图 5为本发明的架构图 2。 UE通过 HeNB接入 EPS的架构中存在 HeNB GW。 H(e)NB Policy Function通过 Tl接口与 H(e)NB GW进行信息交互, 通 过 T2接口与 SeGW交互。 H(e)NB和 SeGW分设。
图 6为基于图 4的架构, 根据本发明实施例的 Η(»ΝΒ Policy Function获 取 H(e)NB位置信息的流程, 该流程包括如下步骤:
步骤 601 , H(e)NB上电后, 与宽带接入进行交互。 该过程中, 宽带接入 可能对 H(e)NB进行接入认证。 宽带接入为 H(e)NB分配 IP地址, 表示为 IP Address 1 ;
步骤 602, H(e)NB根据配置信息找到 SeGW, 并与 SeGW进行 IKEv2信 令交互以建立 IPSec SA。 H(e)NB发送 IKEv2信令的源地址为 IP Address 1 , 源端口号为 Portl (通常取值为 500 ) 。 由于 H(e)NB与 SeGW之间可能存在 网络地址转换( Network Address Translation, 简称 NAT ) , 因此 SeGW收到 的 IKEv2信令的源地址和源端口号可能已经发生了转换。 SeGW收到的 IKEv2 信息的源地址为 IP Address2,源端口号为 Port2。若不存在 NAT,则 IP Address2 等于 IP Addressl , Port2 = Portl , 若存在 NAT, 则不相等。 SeGW保存 IP Address2和 Port2作为 IPSec外部隧道信息。其中源端口号 Port2也是可选的, 即当 H(e)NB与 SeGW之间存在 NAT时, IPSec外部隧道信息需要包括源端 口号 Port2。 在这个过程中 , H(e)NB还会向 SeGW请求分配远端 IP地址用于 与 H(e)NB GW进行交互。该 IP地址表示为 IP Address3。 IPSec外部隧道信息 可能还包括其他信息, 如 IKV2信令的目的地址和目的端口号等。 为了便于 描述, SeGW获得的 H(e)NB的源地址(包括 H(e)NB与 SeGW之间存在 NAT 和不存在 NAT两种情况),称为 H(e)NB本地 IP地址。对于 H(e)NB与 SeGW 之间不存在 NAT , H(e)NB 本地 IP 地址就可以用于固定宽带接入网定位 H(e)NB, 若存在 NAT, 则 H(e)NB本地地址和源端口号可以用于固定宽带接 入网定位 H(e)NB;
步骤 603 , H(e)NB通过其与 SeGW建立的 IPSec SA与 H(e)MS交互, 进 行注册。 Η(»ΝΒ向 H e)MS提供 Η(»ΝΒ的设备标识以及可选的位置信息; H(e)MS向 H(e)NB提供 S1接口的选择地址, 即本实施例中的 H(e)NB GW的 IP地址; 步骤 604, H(e)NB通过其与 SeGW建立的 IPSec SA与 H(e)NB GW交互, 进行注册, 即 H(e)NB发起 SI Setup流程。 H(e)NB向 H(e)NB GW上报小区 标识( Cell ID )。 若 H(e)NB支持 CSG, 那么 H(e)NB还会上报其支持的 CSG ID。 若 H(e)NB GW与 SeGW不是合设的, 那么 SeGW将步骤 602中获得的 IPSec外部隧道信息发送给 H(e)NB GW;
SeGW将 IPSec外部隧道信息发送给 H(e)NB GW可以釆用两种方法: ( 1 )先通过 603步将 IPSec外部隧道信息发送给 H(e)NB, 然后再由 H(e)NB 将 IPSec外部隧道信息发送给 H(e)NB GW。 ( 2 ) SeGW在 H(e)NB发起的 SI setu 流程中直接加入 IPSec外部隧道信息发送给 H(e)NB GW。 ( 3 ) SeGW 与 H(e)NB接口, SeGW通过新定义消息将 IPSec外部隧道信息发送给 H(e)NB GW。
步骤 605 , H(e)NB GW向 H(e)NB Policy Function发送 Tl会话建立消息, 消息中携带步骤 602中获得的 IPSec外部隧道信息;
步骤 606, H(e)NB Policy Function保存 IPSec外部隧道信息后, 返回 T1 会话建立应答消息给 H(e)NB GW;
步骤 607 , H(e)NB Policy Function根据 IPSec外部隧道信息中的 H(e)NB 本地 IP地址, 根据本地配置或 DNS查找获取宽带策略控制框架(BPCF ) 的 地址或 BPCF位于的固定宽带接入网的入口点。 H(e)NB Policy Function向所 述 BPCF发送 S9*会话建立消息, 消息中携带 IPSec外部隧道信息;
步骤 608 , BPCF返回 S9*会话建立应答消息给 H(e)NB Policy Function。 图 7为基于图 5的架构, 根据本发明实施例的 H ( e)NB Policy Function获 取 H(e)NB位置信息的流程, 该流程包括如下步骤:
步骤 701 , H(e)NB上电后, 与宽带接入进行交互。 该过程中, 宽带接入 可能对 H(e)NB进行接入认证。 宽带接入为 H(e)NB分配本地 IP地址, 表示 为 IP Address 1 ;
步骤 702, H(e)NB根据配置信息找到 SeGW, 并与 SeGW进行 IKEv2信 令交互以建立 IPSec SA。 H(e)NB发送 IKEv2信令的源地址为 IP Addressl , 源端口号为 Portl (通常取值为 500 ) 。 由于 H(e)NB与 SeGW之间可能存在 NAT, 因此 SeGW收到的 IKEv2信令的源地址和源端口号可能已经发生了转 换。 SeGW收到的 IKEv2信息的源地址为 IP Address2, 源端口号为 Port2。 若 不存在 NAT, 则 IP Address2等于 IP Address 1 , Port2 = Portl , 若存在 NAT, 则不相等。 SeGW保存 IP Address2和 Port2作为 IPSec外部隧道信息。 其中 源端口号 Port2也是可选的, 即当 H(e)NB与 SeGW之间存在 NAT时, IPSec 外部隧道信息需要包括源端口号 Port2。在这个过程中, H(e)NB还会向 SeGW 请求分配远端 IP地址用于与 H(e)NB GW进行交互。 该 IP地址表示为 IP Address3。 IPSec外部隧道信息可能还包括其他信息, 如 IKV2信令的目的地 址和目的端口号等。 为了便于描述, SeGW获得的 H(e)NB 的源地址(包括 H(e)NB与 SeGW之间存在 NAT和不存在 NAT两种情况 ) , 称为 H(e)NB本 地 IP地址。 对于 H(e)NB与 SeGW之间不存在 NAT, H(e)NB本地 IP地址就 可以用于固定宽带接入网定位 H(e)NB , 若存在 NAT , 则 H(e)NB本地地址和 源端口号可以用于固定宽带接入网定位 H(e)NB; ;
步骤 703 , SeGW向 H(e)NB Policy Function发送 T2会话建立消息, 消息 中携带 IPSec外部隧道信息以及 IP Address3;
步骤 704 , H(e)NB Policy Function保存 IPSec 外部隧道信息以及 IP Address3后, 返回 Τ2会话建立应答消息给 SeGW;
步骤 705, H(e)NB通过其与 SeGW建立的 IPSec SA与 H(e)MS交互, 进 行注册。 Η(»ΝΒ向 H e)MS提供 Η(»ΝΒ的设备标识以及可选的位置信息; H(e) MS向 H(e)NB提供 SI接口的选择地址,即本实施例中的 H(e)NB GW的 IP地址;
步骤 706, H(e)NB通过其与 SeGW建立的 IPSec SA与 H(e)NB GW交互, 进行注册, 即 H(e)NB发起 SI Setup流程。 H(e)NB向 H(e)NB GW上报小区 标识 Cell ID。若 H(e)NB支持 CSG,那么 H(e)NB还会上报其支持的 CSG ID。 H(e)NB GW获取 H(e)NB的远端地址 IP Address3;
步骤 707 , H(e)NB GW向 H(e)NB Policy Function发送 Tl会话建立消息, 消息中携带 IP Address3;
步骤 708, H(e)NB Policy Function保存信息, 即 IP Address3 , 并根据 IP Address3将 Tl会话和 T2会话进行关联,从而获取 T2会话对应的 IPSec外部 隧道信息。 H(e)NB Policy Function返回 Tl会话建立应答消息; 步骤 709, H(e)NB Policy Function根据 IPSec外部隧道信息中的 H(e)NB 本地 IP地址,根据本地配置或 DNS查找获取 BPCF的地址或 BPCF位于的固 定宽带接入网的入口点。 H(e)NB Policy Function向 BPCF发送 S9*会话建立消 息, 消息中携带 IPSec外部隧道信息;
步骤 710, BPCF返回 S9*会话建立应答消息。
当按照图 6或图 7的流程, BPCF获得 IPSec外部隧道信息, BPCF可以 根据 IPSec外部隧道信息定位到 H(e)NB宽带接入的位置,如具体的线路标识 等。 这个过程中, BPCF可能会和宽带接入中的其他网元进行交互 (如 BNG、 NAT等), 从而可以获得 H(e)NB接入的宽带线路的资源可用情况。
当按照图 6或图 7的流程, H(e)NB完成注册后, UE便可接入到该 H(e)NB。 基于现有技术, UE可以通过附着流程、切换流程以及跟踪区或路由区更新流 程等接入到该 H(e)NB。在这些流程的过程中, H(e)NB GW可以获得用户 CSG 信息。 若 H(e)NB为闭合模式, 那么接入该 H(e)NB的 UE均是 CSG用户, H(e)NB GW获得 UE所属的 CSG标识。如果 H(e)NB为混合模式,那么 H(e)NB GW还可获得成员指示关系, 该指示分为 CSG用户和非 CSG用户。
下面结合图 8、 图 9和图 10分别对 EPS承载建立、 删除和修改流程来说 明本发明中对家用基站接入进行策略控制的具体方法。
图 8是根据本发明实施例在 EPS创建承载流程中基于宽带接入线路的可 用情况进行策略控制的流程图,该图描述了通过 HeNB接入 EPS建立的 PDN 连接, UE因访问业务而需要请求新的 QoS资源, 网络决定发起建立专有承 载的流程。 该流程包括如下步骤:
步骤 801: P-GW向 S-GW发送创建承载请求消息, 该消息中携带承载的 QoS参数, 其中包括 QoS类别标识( Quality Class Identifier, QCI ) 、 分配保 持优先级( Allocation and Retention Priority, ARP ) 、 GBR和 MBR (最大速 率 )。 P-GW的触发来自于 PCRF的 PCC规则提供、 P-GW的本地配置或 UE 的 QoS请求;
步骤 802: S-GW向 MME发送创建承载请求消息, 该消息中携带承载的 QoS参数, 包括 QCI、 ARP、 GBR和 MBR;
步骤 803: MME向 HeNB GW发送承载建立请求消息, 该消息中携带承 载的 QoS参数, 包括 QCI、 ARP、 GBR和 MBR;
步骤 804: HeNB GW向 H(e)NB Policy Function发送 Tl会话修改请求消 息,消息中携带请求分配的带宽 BR-Allocation,取值为 GBR,表示 HeNB GW 请求 H(e)NB Policy Function分配的带宽为 GBR;
步骤 805: H(e)NB Policy Function向 BPCF发送 S9*会话修改消息, 消息 中携带带宽资源分配指示信息, 以及请求分配的带宽 BR-Allocation, 取值为 GBR, 表示 H(e)NB Policy Function请求 BPCF分配的带宽为 GBR;
步骤 806: BPCF根据 H(e)NB Policy Function的请求执行策略。 BPCF或 委托其他网元根据 HeNB接入的宽带线路当前可用带宽情况进行资源接纳控 制 (即固定宽带接入网执行资源接纳控制) 。 如果剩余的可用带宽大于等于 BR-Allocation,则 BPCF接受 HeNB Policy Function的请求,并在向 HeNB Policy Function返回的应答消息中携带接受指示,同时 BPCF将从宽带线路当前可用 带宽中扣除 BR-Allocation;如果剩余的可用带宽小于 BR-Allocation,则 BPCF 拒绝 HeNB Policy Function的请求, 并在向 HeNB Policy Function返回的应答 消息中携带拒绝指示, 同时携带 BPCF能够接受的带宽 BR;
步骤 807: H(e)NB Policy Function将 BPCF返回的应答消息中携带的接受 或拒绝指示以及 BPCF返回的能够接受的带宽 BR发送给 HeNB GW;
步骤 808: HeNB GW将进行如下策略决策, 即执行接纳控制:
( a )如果 HeNB GW接收到的是接受指示, 则执行步骤 818;
( b )如果 HeNB GW接收到的是拒绝指示, 则 HeNB GW进一步执行如 下逻辑判断:
( bl )如果 HeNB接入的模式为开放模式, HeNB GW根据 ARP将该承 载与该用户自己建立的其他 GBR承载以及通过同一个宽带线路接入的其他 用户建立的其他 GBR承载进行比较:
如果该承载无法抢占其他的承载资源, 则执行步骤 809;
如果该承载可以抢占其他承载的资源, 并且可抢占其他承载的带宽 BR, 与 BPCF返回的能够接受的带宽 BR之和大于等于 GBR (即 BR'+BR> = GBR), 则执行步骤 812; 若 BR'+BR<GBR, 则执行步骤 809;
( i )如果 HeNB接入的模式是混合模式, 并且该承载对应的 UE的成 员关系为非 CSG用户, 则:
( b21 )如果存在有该用户自己建立的其他 GBR承载或通过同一个宽带 线路接入的其他非 CSG用户建立的其他 GBR承载,那么 HeNB GW根据 ARP 将承载与其他承载进行比较, 如果该承载无法抢占其他承载的资源, 则执行 步骤 809; 如果该承载可以抢占其他承载的资源, 并且可抢占其他承载的带 宽 BR'与 BPCF返回的能够接受的带宽 BR之和大于等于 GBR (即 BR'+BR> = GBR), 则执行步骤 812; 若 BR,+BR<GBR, 则执行步骤 809;
( b22 )如果不存在有该用户自己建立的其他 GBR承载或通过同一个宽 带线路接入的其他非 CSG用户建立的其他 GBR承载, 则执行步骤 809。
( b3 )如果 HeNB的接入模式是混合模式, 并且该承载对应的 UE的成 员关系为 CSG用户, 则:
( b31 )如果存在有通过同一个宽带线路接入的其他非 CSG用户建立的 其他 GBR承载, 并且该承载可抢占其他非 CSG用户建立的承载带宽 BR'与 BPCF返回的能够接受的带宽 BR之和大于等于 GBR (即 BR,+BR> = GBR), 则执行步骤 812; 若可抢占其他非 CSG用户建立的承载带宽 BR'与 BPCF返 回的能够接受的带宽 BR之和小于 GBR (即 BR,+BR<GBR), 那么 HeNB GW 进一步根据 ARP将该承载与该用户自己建立的其他 GBR承载或通过同一个 宽带线路接入的其他 CSG用户建立的其他承载进行比较,若该承载无法抢占 其他承载的资源, 则执行步骤 809; 如果该承载可以抢占 CSG用户建立的其 他承载的资源,并且可抢占其他承载的带宽 BR' (包括非 CSG用户建立的承载 和 CSG用户建立的承载)与 BPCF返回的能够接受的带宽 BR之和大于等于 GBR (即 BR'+BR> = GBR), 则执行步骤 812; 若 BR'+BR<GBR, 则执行步骤 809;
( b32 )如果不存在有通过同一个签约固网线路接入的非 CSG用户建立 的其他 GBR承载, 那么 HeNB GW根据 ARP将承载与该用户自己建立的其 他 GBR承载或通过同一个宽带线路接入的其他 CSG用户建立的其他承载进 行比较, 如果该承载无法抢占其他承载的资源, 则执行步骤 809。 如果该承 载可以抢占其他承载的资源, 并且可抢占其他承载的带宽 BR,与 BPCF返回 的能够接受的带宽 BR之和大于等于 GBR (即 BR,+BR> = GBR), 则执行步骤 812; 若 BR'+BR<GBR, 则执行步骤 809;
( b4 )如果 HeNB的接入模式是闭合模式, 那么 HeNB GW根据 ARP将 该承载与该用户自己建立的其他 GBR承载或通过同一个宽带线路接入的其 他用户建立的 GBR承载进行比较, 如果该承载无法抢占其他承载的资源, 则 执行步骤 809。 如果该承载可以抢占其他承载的资源, 并且可抢占其他承载 的带宽 BR'与 BPCF 返回的能够接受的带宽 BR之和大于等于 GBR (即 BR,+BR> = GBR), 则执行步骤 812; 若 BR,+BR<GBR, 则执行步骤 809;
在其他实施例中 , HeNB GW在进行决策时, 只根据承载的 ARP进行, 即根据 ARP将该承载与该用户自己建立的其他 GBR承载或通过同一个宽带 线路接入的其他用户建立的 GBR承载进行比较,如果该承载无法抢占其他承 载的资源, 则执行步骤 809。 如果该承载可以抢占其他承载的资源, 并且可 抢占其他承载的带宽 BR'与 BPCF返回的能够接受的带宽 BR之和大于等于 GBR (即 BR'+BR> = GBR), 则执行步骤 812; 若 BR'+BR<GBR, 则执行步骤 809;
步骤 809: HeNB GW向 MME返回承载建立应答, 拒绝承载建立; 步骤 810: MME向 S-GW返回创建承载应答, 拒绝承载建立;
步骤 811 : S-GW向 P-GW返回创建承载应答,拒绝承载建立,流程结束; 步骤 812: HeNB GW向 MME发送承载释放指示, 指示释放 HeNB GW 在步骤 808中决定要抢占的承载带宽资源;
步骤 813: MME发起专有承载去激活流程, 释放被抢占的其他承载的资 源。 该步骤可利用现有的技术实现, 在此不再赘述;
步骤 814: 若在步骤 808 中, BR'+BR = GBR, 则直接执行 818; 若
BR'+BR>GBR, 那么 HeNB GW向 H(e)NB Policy Function发送 Tl会话修改 消息, 消息中携带带宽资源分配指示信息, 以及请求分配的带宽 BR- Allocation, 取值为 GBR-BR'; 步骤 815: H(e)NB Policy Function向 BPCF发送 S9*会话修改消息, 消息 中携带资源分配指示信息, 以及请求分配的带宽 BR-Allocation, 取值为 GBR-BR';
步骤 816: BPCF接受 H(e)NB Policy Function的请求,并在向 H(e)NB Policy Function返回的 S9*会话修改应答消息中携带接受指示, 同时 BPCF将从宽带 线路当前可用带宽中扣除 GBR-BR';
步骤 817: H(e)NB Policy Function向 HeNB GW返回 Tl会话修改应答消 息, 消息中携带接受指示;
步骤 818: HeNB GW进一步与 HeNB交互, 建立无线承载;
步骤 819: HeNB GW向 MME返回承载建立应答消息, 接受承载建立; 步骤 820: MME向 S-GW返回创建承载应答消息, 接受承载建立; 步骤 821 : S-GW向 P-GW返回创建承载应答消息, 接受承载建立。
在其他实施例中, 在步骤 804中, HeNB GW向 H(e)NB Policy Function 发送消息中携带带宽信息外,还会携带 QCI、 ARP以请求 QoS授权;相应地, 步骤 805中, 除携带带宽信息外, 还携带 QCI、 ARP以向 BPCF请求 QoS授 权; 步骤 806中, BPCF在执行资源接纳控制后(执行资源接纳控制时, 除了 考虑目前可用的剩余带宽是否能够满足请求的带宽外, 还会综合考虑 QCI和 /或 ARP, 以决定是否接受或拒绝 QoS授权请求), 向 H(e)NB Policy Function 返回 QoS授权信息,携带接受或拒绝指示,拒绝指示时还携带可接受的带宽; 步骤 807中, H(e)NB Policy Function向 HeNB GW返回 QoS授权信息, 携带 接受或拒绝指示, 拒绝指示时还携带可接受的带宽; 步骤 808中, HeNB GW 根据 QoS授权的信息执行接纳控制 (执行的逻辑判断与上述实施例中的一 致) 。
UE通过 HNB接入 EPS建立的 PDN连接, UE因访问业务而需要请求新 的 QoS 资源, 网络决定发起建立专有承载的流程与此类似。 不同之处在于 S-GW收到 P-GW发送的创建承载请求消息后, 向 SGSN发送创建承载请求 消息, SGSN收到消息后向 HNB GW发送无线接入承载指派请求消息新建无 线承载, HNB GW与 BPCF交互请求固定宽带接入网的接纳控制。 HNB GW 根据接纳控制结果执行进一步的操作, 如接受时, 进一步与 HNB交互, 建立 无线承载, 拒绝时, 进一步执行接纳控制或拒绝无线承载的建立。
图 9是根据本发明实施例在 EPS删除承载流程中基于宽带接入线路的可 用情况进行策略控制的流程图。 该流程包括如下步骤:
步骤 901 : P-GW向 S-GW发送删除承载请求消息。 P-GW触发来自于
PCRF的请求、 P-GW的本地配置或 UE的请求。 其中所删除的承载为 GBR 承载;
步骤 902: S-GW向 MME发送删除承载请求消息;
步骤 903: MME向 HeNB GW发送承载删除请求消息;
步骤 904: HeNB GW向 H(e)NB Policy Function发送请求 T1会话修改消 息, 消息中携带请求带宽资源释放指示信息, 以及请求释放的带宽 BR-Release , 取值为请求删除的承载的 GBR;
步骤 905: H(e)NB Policy Function向 BPCF发送 S9*会话修改消息, 消息 中携带请求带宽资源释放指示信息, 以及请求释放的带宽 BR-Release, 取值 为请求删除的承载的 GBR;
步骤 906: BPCF接受 H(e)NB Policy Function的请求,并在向 H(e)NB Policy Function返回的 S9*会话修改应答消息中携带接受指示, 同时 BPCF将在宽带 线路当前可用带宽中增加 GBR;
步骤 907: H(e)NB Policy Function向 HeNB GW返回 Tl会话修改应答消 息;
步骤 908: HeNB GW根据接受指示, 允许释放承载(即执行接纳控制 )。 HeNB GW与 HeNB 交互, 释放无线承载;
步骤 909: HeNB GW向 MME返回承载删除应答;
步骤 910: MME向 S-GW返回删除承载应答;

步骤 1312: SGSN发起 PDP上下文去激活流程, 释放被抢占的其他 PDP 上下文的资源。 该步骤可利用现有的技术实现, 在此不再赘述;
步骤 1313: 若在步骤 1307中, BR'+BR = GBR增量, 则直接执行 1317; 若 BR,+BR>GBR增量, 那么 HNB GW向 H(e)NB Policy Function发送 Tl会 话修改消息, 消息中携带带宽资源分配指示信息, 以及请求分配的带宽 BR-Allocation, 取值为 GBR增量 -BR,;
