The home base station serving the users in this closed subscriber group has the same CSG ID. When a closed subscriber group has only one home base station service, the closed subscriber group can also directly identify the home base station identity (e.g., BS ID).

Description

资源管理方法、 系统及家用基站策略功能
技术领域
本发明涉及通信领域, 具体而言, 涉及一种资源管理方法、 系统及家用 基站策略功能。 背景技术
第三代合作伙伴计划 ( 3rd Generation Partnership Project, 简称为 3GPP ) 的演进的分组系统( Evolved Packet System, 简称为 EPS ) 由演进的通用地面 无线接入网 ( Evolved Universal Terrestrial Radio Access Network , 简称为 E-UTRAN ) 、 移动管理单元 ( Mobility Management Entity, 简称为 MME ) 、 服务网关( Serving Gateway, 简称为 S-GW )、分组数据网络网关( Packet Data Network Gateway,简称为 P-GW )、归属用户服务器( Home Subscriber Server, 简称为 HSS )组成。 图 1是根据相关技术的非漫游场景下的家用基站(Home evolved NodeB,简称为 HeNB )接入 EPS的架构示意图。下面结合图 1对 EPS 的架构进行说明。
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有一个家 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 ( Broadband Access, 简 称 BBF ) )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通过 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。
在家用基站通过签约固网线路接入的情况下,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(包括 H(e)NB GW和 SeGW )接口, 并对家用基站接入进行策略控制。 图 4是 HeNB接入 时, 不存在 HeNB GW的架构, 此时 H(e)NB Policy Function分别与 SeGW和 MME接口。
图 5 为现有技术中 H(e)NB 上电后, H(e)NB 子系统与 H(e)NB Policy Function的交互流程图。
步骤 S501 : H(e)NB 上电后, 获得 BBF接入网分配的用户终端设备 ( Customer Premises Equipment, 简称 CPE ) IP地址, H(e)NB用 CPE IP地址 与 SeGW进行 IKEv2信令交互, 建立 IPSec隧道。 在这个过程中, SeGW为 H(e)NB分配 H(e)NB IP地址 , 用于 H(e)NB与其他 3GPP网元交互;
步骤 S502: SeGW向 H(e)NB Policy Function通知 CEP IP地址和 H(e)NB IP地址的关联关系; 步骤 S503: H(e)NB Policy Function保存关联关系后, 返回接受消息; 步骤 S504: H(e)NB与 H(e)NB GW或 MME建立 S1或 Iuh连接; 步骤 S505: H(e)NB GW或 MME与 H(e)NB Policy Function建立 T2会话, 其中携带 CSG ID以及 H(e)NB IP地址;
步骤 S506: H(e)NB Policy Function根据 H(e)NB IP地址将 T2会话与步骤
S502进行关联, 从而获得该 H(e)NB的 CPE IP地址, H(e)NB Policy Function 根据 CPE IP地址确定 H(e)NB接入的 BBF接入网的 BPCF ( Broadband Policy Control Framework, 宽带策略控制架构) 。 H(e)NB Policy Function向 BPCF 建立 S9*会话, 携带 CPE IP地址;
步骤 S507: BPCF返回应答消息;
步骤 S508: H(e)NB Policy Function向 H(e)NB GW或 MME返回应答消 息。
通过上述流程, H(e)NB Policy Function与 BPCF建立了的 S9*会话, 该 BPCF用于对 H(e)NB接入的固网 Backhaul (回程线路 )进行策略控制。
图 6为现有技术中, UE通过 H(e)NB初始附着或业务请求时, H(e)NB Policy Function与 BPCF交互的流程图。
步骤 S601 : UE执行初始附着或业务请求 (空闲态到连接态转换); 步骤 S602: MME或 SGSN经 H(e)NB GW向 H(e)NB发送承载建立请求 或无线接入承载指派请求;
步骤 S603: H(e)NB GW收到上述消息后, 向 H(e)NB Policy Function发 送请求承载授权的消息, 消息中携带 H(e)NB IP地址, 以及 QoS信息。 若该 H(e)NB为混合模式, 还会携带该 UE的 CSG成员指示;
步骤 S604: H(e)NB Policy Function根据 H(e)NB IP地址确定 CPE IP地址, 釆用图 5中建立的 S9*会话向 BPCF请求 QoS授权, 携带 QoS信息;
步骤 S605: BPCF根据 QoS信息, 以及 H(e)NB接入的固网 Backhaul当 前的资源情况进行接纳控制, 向 H(e)NB Policy Function返回应答消息。 BPCF 可以接受或拒绝 QoS授权;
步骤 S606: H(e)NB Policy Function向 H(e)NB GW返回应答消息, 接受 或拒绝授权;
步骤 S607: H(e)NB向 MME或 SGSN返回承载建立或无线接入承载指派 应答。
步骤 S603 -步骤 S606与步骤 S607是同时进行的。
若在步骤 S606中, H(e)NB GW接收到拒绝授权的指示,那么 H(e)NB GW 将发起承载删除请求或请求释放无线接入资源的无线接入承载指派请求。
图 7是现有技术中, 在承载(PDN上下文)激活 /修改 /去激活过程中, H(e)NB Policy Function与 BPCF的交互流程。
步骤 S701 : MME或 SGSN收到激活 /修改 /去激活承载请求消息; 步骤 S702: MME或 SGSN经 H(e)NB GW向 H(e)NB发送相应的请求消 息;
步骤 S703: H(e)NB GW收到上述消息后, 向 H(e)NB Policy Function发 送请求承载授权的消息, 消息中携带 H(e)NB IP地址, 以及 QoS信息。 若该 H(e)NB为混合模式, 还会携带该 UE的 CSG成员指示;
步骤 S704: H(e)NB Policy Function根据 H(e)NB IP地址确定 CPE IP地址, 釆用图 5中建立的 S9*会话向 BPCF请求 QoS授权, 携带 QoS信息;
步骤 S705: BPCF根据 QoS信息, 以及 H(e)NB接入的固网 Backhaul当 前的资源情况进行接纳控制, 向 H(e)NB Policy Function返回应答消息。 BPCF 可以接受或拒绝 QoS授权;
步骤 S706: H(e)NB Policy Function向 H(e)NB GW返回应答消息, 接受 或拒绝授权;
步骤 S707: H(e)NB向 MME或 SGSN返回承载建立或无线接入承载指派 应答。
步骤 S703 -步骤 S706与步骤 S707是同时进行的。
若在步骤 S706中, H(e)NB GW接收到拒绝授权的指示,那么 H(e)NB GW 将发起承载删除请求或请求释放无线接入资源的无线接入承载指派请求, 以 便拒绝该 UE的承载 /修改请求。
通过以上 3个流程,现有技术能够实现所有接入该 H(e)NB的 UE请求分 配的资源不会超过该 H(e)NB连接的 backhual当前可用资源的总和, 从而保 证了每个 UE的每个业务的顺利进行。
以上流程中, 当 BPCF根据当前资源情况拒绝授权请求后, 无论当前承 载或用户的当前用户状况如何, 相应承载的建立或修改请求都将被拒绝, 对 于承载或用户级别较高的情形, 这显然不够合理。 发明内容

本发明的较佳实施方式
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。
根据现有流程, 在 H(e)NB为混合模式的情况下, 若已有非 CSG的成员 用户接入 H(e)NB访问业务, 当前 backhaul资源已用尽或即将用尽, 当 CSG 成员用户发起接入或承载建立 /修改时, BPCF 将根据当前资源情况拒绝该 CSG成员用户的接入或承载建立 /修改, 这显然很不合理。 同样的, 如果优先 级较低的承载接入后, 拒绝高优先级的承载接入; 或非紧急业务承载接入后, 拒绝紧急业务的承载接入, 都会出现不合理的资源利用。
为了合理利用资源, 本发明实施方式在当前资源不足的情况下, 家用基 站策略功能( H(e)NB Policy Function )根据预先制定的策略执行接纳控制, 通 过释放其他承载占用资源的方式为当前承载获取足够的资源, 实现资源的重 分配及合理利用。 例如, 对于混合模式, 当建立或修改 CSG成员的承载资源不足时, 中断 或删除那些非 CSG成员的接入或承载。 此外, 每个承载也是有优先级的, 因 此对于相同 CSG成员关系的用户承载, 当 backhual资源用尽, BPCF返回拒 绝授权时, 应该按照承载的优先级来进行资源的重分配。
如图 12所示, 本发明资源管理方法, 该方法包括:
步骤 101 : 家用基站策略功能(H(e)NB Policy Function )接收宽带策略控 制架构 (BPCF )发送的请求 QoS授权的应答消息;
步骤 102: 所述请求 QoS授权的应答消息指示拒绝时, 所述家用基站策 略功能根据预置的策略执行接纳控制。
所述家用基站策略功能根据预置的策略执行接纳控制包括:
所述家用基站策略功能根据预置的策略判断所述请求 QoS授权的承载是 否抢占其他承载资源;
判断抢占时,所述家用基站策略功能触发所述被抢占承载的去激活流程。 判断抢占时, 所述家用基站策略功能还向承载授权的请求端发送指示同 意承载授权的应答消息, 判断不抢占时, 则向所述请求端发送指示拒绝承载 授权的应答消息。
根据保证不同的承载或用户的业务体验, 可以制定不同的策略, 策略可 以包括被抢占承载的选择范围策略、 被抢占承载的选择顺序策略或资源抢占 的条件等内容。
所述策略为:家用基站模式为混合模式的情况下,根据闭合用户组( CSG ) 成员关系执行接纳控制; 或, 根据分配保持优先级(ARP )执行接纳控制; 或,
家用基站为开放模式或闭合模式时, 根据 ARP执行接纳控制; 家用基站 模式为混合模式情况下, 根据闭合用户组( CSG )成员关系和 /或 ARP执行接 纳控制。
不同的家用基站模式可以制定不同的策略内容:
家用基站为开放模式或闭合模式时, 根据分配保持优先级( ARP ) , 所 述承载抢占其他用户承载的资源; 例如: 从低于当前承载分配保留优先级 ( ARP ) 的承载中选择满足资源抢占条件的被抢占承载;
家用基站模式为混合模式情况下, 所述承载对应的用户为闭合用户组
( CSG )成员时, 所述承载抢占非 CSG成员用户承载的资源和 /或根据 ARP 抢占其他 CSG成员用户承载的资源; 所述承载对应的用户为非 CSG成员时, 根据分配保持优先级( ARP ) , 所述承载抢占其他非 CSG成员用户承载的资 源。
家用基站为混合模式且所述承载对应的用户为 CSG成员时,被抢占承载 的选择顺序为先从非 CSG成员的承载中选择, 再从 CSG成员的承载中选择。
所述被抢占的承载为一个或多个并且所述一个或多个被抢占承载的资源 大于或等于所述承载请求授权资源。
所述请求 QoS授权的应答消息指示拒绝授权时, 同时携带当前可用资源
所述家用基站策略功能判断抢占资源, 若被抢占资源大于当前承载请求 分配资源, 则向所述 BPCF请求释放差额资源; 若被抢占资源小于当前承载 请求分配资源, 则向所述 BPCF请求分配差额资源。
所述请求承载授权的消息中携带当前承载标识, 所述家用基站策略功能 发起承载去激活流程时, 触发被抢占承载的去激活的消息中携带被抢占承载 的承载标识。
下文中将参考附图并结合实施例来详细说明本发明。 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组合。

图 11是根据本发明实施例在承载(PDN上下文)激活 /修改 /去激活过程 中, H(e)NB Policy Function与 BPCF的又一交互流程。 该流程包括如下步骤: 步骤 S1101 : MME或 SGSN收到来自核心网的激活 /修改 /去激活承载
( PDP上下文)请求消息;
步骤 S1102: MME或 SGSN向 H(e)NB GW向发送激活 /修改 /去激活承载 请求或无线接入承载指派请求携带激活 /修改 /去激活指示;
步骤 S1103: H(e)NB GW收到上述消息后, H(e)NB GW向 H(e)NB发送 激活 /修改 /去激活承载请求或无线接入承载指派请求携带激活 /修改 /去激活指 示;
步骤 S1104: H(e)NB执行相应操作后, 返回应答消息; H(e)NB GW向 MME或 SGSN返回发送激活 /修改 /去激活承载请求或无线接入承载指派请求 携带,携带接受指示。此时, UE请求建立的无线承载建立完成。即 H(e)NB GW 先默认允许承载激活 /修改 /去激活。
步骤 S1105: 该步骤与步骤 S1103的同时执行。 H(e)NB GW收到上述消 息后, 向 H(e)NB Policy Function发送请求承载授权的消息,
若是激活请求, 则消息中携带 H(e)NB IP地址, QoS请求承载标识, 以 及 QoS信息。 若该 H(e)NB为混合模式, 还会携带该 UE的 CSG成员指示。 QoS请求承载标识用于 H(e)NB GW与 H(e)NB Policy Function交互时唯一标 识该承载。 QoS请求承载标识, 可以是 H(e)NB GW分配, 也可以釆用用户标 识和 EPS承载标识( EPS系统)组合或者用户标识和 NSAPI ( UMTS系统) 组合的体现;
若是修改请求, 则消息中携带 QoS请求承载标识, 以及 QoS信息; 若是去激活请求, 则消息中携带 QoS请求承载标识。
对于 UMTS系统,对于 Non-GBR的 PDP上下文, QoS信息至少包括 Trafic class, Allocation/Retention Priority, MBR; 对于 GBR的 PDP上下文, QoS信 息至少包括 Trafic class, Allocation/Retention Priority, GBR, MBR。 对于 EPS系统, 对于 Non-GBR承载, QoS信息包括 QCI、 ARP、 MBR; 对于 GBR承载, QoS信息包括 QCI、 ARP、 GBR、 MBR。
步骤 SI 106: 对于激活请求, H(e)NB Policy Function根据 H(e)NB IP地址 确定 CPE IP地址, 釆用图 5中建立的 S9*会话向 BPCF请求 QoS授权, 携带 请求分配的带宽 BR-Allocation和请求分配资源指示;
其中,若从 H(e)NB GW获得的 QoS信息中包含 GBR,那么 BR-Allocation 可以设置为 QoS信息中的 GBR;
若从 H(e)NB GW获得 QoS信息中不包含 GBR, 那么 H(e)NB Policy Function可以执行两种策略:
(1)根据 MBR或 UE-AMBR以及本地策略设置 BR-Allocatio
(2)H(e)NB Policy Function本地处理, 不向 BPCF请求 QoS授权。
对于修改请求, H(e)NB Policy Function根据 QoS请求承载标识,确定 S9* 会话, 向 BPCF请求 QoS授权通过 S9。
若从 H(e)NB GW获得的 QoS信息中包含 GBR,那么 BR-Allocation可以 设置为更新前后 QoS信息中的 GBR的差值,若更新后增加了带宽,则 H(e)NB Policy Function向 BPCF的消息中携带请求分配的带宽 BR-Allocation和请求分 配资源指示; 若更新后减少了带宽, 则 H(e)NB Policy Function向 BPCF的消 息中携带请求释放的带宽 BR-Release和请求释放资源指示
若从 H(e)NB GW获得 QoS信息中不包含 GBR, 那么 H(e)NB Policy Function可以执行两种策略:
(1)根据 MBR或 UE-AMBR以及本地策略设置新的带宽, 并且根据更新 前后的差值设置 BR-Allocation或 BR-Release。
(2) H(e)NB Policy Function本地处理, 不向 BPCF请求 QoS授权。
步骤 SI 107:若是请求分配带宽, BPCF根据 BR-Allocation, 以及 H(e)NB 接入的固网 Backhaul 当前的资源情况进行接纳控制, 向 H(e)NB Policy Function返回应答消息。 若当前可用带宽大于或等于 BR-Allocation, 则 BPCF 返回接受指示, 若当前可用带宽消息 BR-Allocation, 则 BPCF拒绝指示, 同 时可以携带可以接受的带宽 BR-Accept。若是请求释放带宽, 则 BPCF返回接 受指示。
步骤 SI 108: H(e)NB Policy Function根据 BPCF的返回消息,执行如下策 略决策。
( a )如果 H(e)NB Policy Function接收到的是接受指示, 则执行步骤 S1111 ;
( b )如果 H(e)NB Policy Function接收到的是拒绝指示,则 H(e)NB Policy Function执行接纳控制:
( bl )如果 H(e)NB接入的模式为开放模式, H(e)NB Policy Function根据 ARP(Allocation/Retention Priority)将该承载 (PDP上下文)与该用户自己建立的 经 BPCF授权的其他承载 (上下文)以及通过同一个 H(e)NB接入的其他用户建 立的经 BPCF授权其他承载 (PDP上下文)进行比较:
如果该承载 (PDP上下文)无法抢占其他的承载 (PDP上下文)资源(该承载 的 ARP(Allocation/Retention Priority) ) , 则执行步骤 S 1112;
如果该承载 (PDP上下文)可以抢占其他承载的资源, 并且可抢占其他承 载 (PDP上下文)的带宽 BR-Allocation,与 BPCF返回的当前可用带宽 BR-Accept 之和大于或等于 BR-Allocation,则执行步骤 SI 109;否则,则执行步骤 S1112;
( i )如果 HeNB接入的模式是混合模式, 并且该承载 (PDP上下文)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经 BPCF授权的其他承载 (PDP上 下文)或通过同一 H(e)NB接入的其他非 CSG用户建立的经 BPCF授权的其他 承载 (PDP上下文),那么 H(e)NB Policy Function根据 ARP(Allocation/Retention Priority)将承载 (PDP上下文)与其他承载 (PDP上下文)进行比较, 如果该承载 (PDP上下文)无法抢占其他承载 (PDP上下文)的资源, 则执行步骤 S1112; 如 果该承载 (PDP上下文)可以抢占其他承载 (PDP上下文)的资源,并且可抢占其 他承载 (PDP 上下文)的带宽 BR-Allocation,与 BPCF 返回的当前可用带宽 BR-Accept之和大于或等于 BR-Allocation, 则执行步骤 SI 1109; 否则, 则执 行步骤 S1112; ( b22 )如果不存在有该用户自己建立的经 BPCF授权的其他承载 (PDP 上下文)或通过同一个 H(e)NB接入的其他非 CSG用户建立的经 BPCF授权的 其他承载 (PDP上下文), 则执行步骤 S1012。
( b3 )如果 HeNB的接入模式是混合模式, 并且该承载(PDP上下文) 对应的 UE的成员关系为 CSG用户, 则:
( b31 )如果存在有通过 H(e)NB接入的其他非 CSG用户建立的经 BPCF 授权的其他承载 (PDP上下文),并且该承载( PDP上下文 )可抢占其他非 CSG 用户建立的经 BPCF授权的承载 ( PDP上下文) 带宽 BR-Allocation,与 BPCF 返回的当前可用带宽 BR-Accept之和大于或等于 BR-Allocation, 则执行步骤 S1109; 否则, 那么 H(e)NB Policy Function根据 ARP(Allocation/Retention Priority)将该承载( PDP上下文 )与该用户自己建立的经 BPCF授权的其他承 载( PDP上下文)或通过同一个 H(e)NB接入的其他 CSG用户建立的经 BPCF 授权的其他承载(PDP上下文)进行比较, 若该承载(PDP上下文)无法抢 占其他承载(PDP上下文) 的资源, 则执行步骤 S1112; 如果该承载(PDP 上下文)可以抢占 CSG用户建立的的经 BPCF授权其他承载(PDP上下文) 的资源, 并且可抢占其他承载(PDP上下文) 的带宽 BR-Allocation,(包括非 CSG用户建立的承载和 CSG用户建立的承载)与 BPCF返回的当前可用带宽 BR-Accept之和大于或等于 BR-Allocation, 则执行步骤 SI 109; 否则, 执行步 骤 S1112;
( b32 )如果不存在有通过同一个 H(e)NB接入的非 CSG用户建立的经
BPCF授权的其他承载(PDP上下文) , 那么 H(e)NB Policy Function根据 ARP(Allocation/Retention Priority)将承载 (PDP上下文)与该用户自己建立的经 BPCF授权的其他承载( PDP上下文)或通过同一个 H(e)NB接入的其他 CSG 用户建立的经 BPCF授权的其他承载 (PDP上下文)进行比较,如果该承载( PDP 上下文)无法抢占其他承载(PDP上下文) 的资源, 则执行步骤 S1112。 如 果该承载可以抢占其他承载( PDP上下文)的资源,并且可抢占其他承载( PDP 上下文)的带宽 BR-Allocation,与 BPCF返回的当前可用带宽 BR-Accept之和 大于或等于 BR-Allocaton, 则执行步骤 S1109; 否则, 执行步骤 S1012;
( b4 )如果 HeNB的接入模式是闭合模式, 那么 H(e)NB Policy Function 根据 ARP(Allocation/Retention Priority)将该承载 (PDP上下文)与该用户自己建 立的经 BPCF授权的其他承载 (PDP上下文)或通过同一个 H(e)NB接入的其他 用户建立的经 BPCF授权的承载 (PDP上下文)进行比较, 如果该承载 (PDP上 下文)无法抢占其他承载 (PDP上下文)的资源, 则执行步骤 S1012。 如果该承 载 (PDP上下文)可以抢占其他承载 (PDP上下文)的资源,并且可抢占其他承载 (PDP上下文)的带宽 BR-Allocation,与 BPCF返回的当前可用带宽 BR-Accept 之和大于或等于 BR-Allocation, 则执行步骤 SI 109; 否则, 执行步骤 S1112; 在其他实施例中 , H(e)NB Policy Function在进行决策时,只根据承载 (PDP 上下文)对应的用户 CSG成员关系进行,即对于混合模式的 H(e)NB,判断 CSG 成员用户的承载 (PDP上下文)能否抢占非 CSG成员用户的经 BPCF授权的承 载 (PDP上下文)的资源。 对于其他模式的 H(e)NB, 不做决策;
在其他实施例中 , H(e)NB Policy Function在进行决策时,只根据承载 (PDP 上下文)对应的 ARP系进行, 判断承载 (PDP上下文)能否抢占其他经 BPCF授 权的承载 (PDP上下文)的资源;
步骤 S1109: H(e)NB Policy Function向 H(e)NB GW发送承载 (PDP上下 文)去激活指示, 携带被抢占的 QoS请求承载标识;
步骤 S1110: H(e)NB GW根据 QoS请求承载标识, 发起释放被抢占的承 载 (PDP上下文)的资源。对于 EPS, 若释放的是默认承载, 则将导致网络拒绝 UE的接入或断开 PDN连接。 流程结束。
若承载 (PDP上下文)的带宽 BR-Allocation'和 BR-Allocation不相等, 则
H(e)NB Policy Function 还 需 与 BPCF 进 行 交 互 , 若 BR-Allocation' >BR- Allocation,则 H(e)NB Policy Function会请求 BPCF释放差 额带宽 BR- Allocation' - BR-Allocation; 否则 H(e)NB Policy Function会请求 BPCF分配差额带宽 BR-Allocation - BR-Allocation'„
步骤 SI 111 : H(e)NB Policy Function向 H(e)NB GW返回承载授权应答消 息,携带接受指示。该消息为步骤 S1105的应答消息。流程结束。 H(e)NB GW 认可在步骤 S1104中完成建立的无线承载;
步骤 SI 112: H(e)NB Policy Function向 H(e)NB GW返回承载授权应答消 息, 携带拒绝指示。 该消息为步骤 S1105的应答消息;
步骤 S1113: H(e)NB GW发起 PDP上下文去激活流程 /承载去激活流程, 释放在步骤 S1104中 UE请求建立的承载。 对于 EPS, 若拒绝的是默认承载, 则将导致网络拒绝 UE的接入或断开 PDN连接。 流程结束。
在以上实施例 1-4中, H(e)NB Policy Function根据家用基站的模式釆用 不同的策略确定被抢占的承载, 系统制定的策略可以灵活制定和改变, 如: 在其他实施例中, H(e)NB Policy Function在进行接纳控制决策时, 只根 据承载 (PDP 上下文)对应的用户 CSG 成员关系进行, 即对于混合模式的 H(e)NB, 判断 CSG成员用户的承载 (PDP上下文)能否抢占非 CSG成员用户 的经 BPCF授权的承载 (PDP上下文)的资源。 对于其他模式的 H(e)NB, 不做 决策;
或, H(e)NB Policy Function在进行接纳控制决策时, 只根据承载 (PDP上 下文)对应的 ARP进行, 判断承载 (PDP上下文)能否抢占其他经 BPCF授权的 承载 (PDP上下文)的资源。
另夕卜, 在实施例 2和 4中, H(e)NB GW向 H(e)NB Policy Function发送请 求承载授权的消息时, 同时向 H(e)NB发送请求承载相关操作的消息, 即由 H(e)NB GW先默认允许承载激活 /修改 /去激活等, 进而, 当 BPCF对相应承 载的 QoS授权请求指示授权或指示拒绝但资源抢占成功时, 可以加快承载的 建立 /激活 /修改 /去激活流程。 可理解地, 在承载授权应答指示拒绝授权时, H(e)NB GW需要发起未经授权的承载的去激活流程。
对于 HeNB接入,并且不存在 H(e)NB GW的场景,由移动性管理网元(如 EPS系统中的 MME )代替 H(e)NB GW实现承载授权的请求端的功能, 相应 的修改不涉及本发明实质, 本发明同样适用。 即, 当 MME收到来自 UE的初 始附着或业务请求,或是 MME收到来自核心网的承载激活 /修改 /去激活请求, 由 MME发起与 H(e)NB Policy Function的交互 , 其他步骤也做相应的修改。
