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 组内用户月艮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。 居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, 享受月艮务质量和业务 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月艮务器中。 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。 同时, 为了实现对 HeNB进行管理, 引入了网元家用基站管理*** ( Home eNodeB Management System , 简称为 HeMS )„ 由于 HeNB接入的固网线路的 QoS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。 jt匕夕卜, 通用移动通信*** ( Universal Mobile Telecommunications System, 简称为 UMTS ) 也支持家用基站 HNB ( Home NodeB ) 的接入。 图 4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 5是根据相 关技术的家乡路由漫游场景下的 HNB接入 UMTS的架构示意图, 图 6是根 据相关技术的本地疏导漫游场景下的 HNB接入 UMTS的架构示意图。 图 4、 图 5和图 6中的架构与图 1、 图 2和图 3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The EPS supports the access of the HeNB, which is a small, low-power base station deployed in indoor places such as homes and offices. Closed Subscriber Group (CSG) is a new concept introduced after the introduction of home base stations. Usually a family or a user inside an enterprise forms a closed user group, which is identified by a CSG ID. The home base station for the user's monthly service in this closed subscriber group has the same CSG ID. When a closed subscriber group is served by only one home base station, the closed subscriber group can also directly identify the home base station identity (e.g., BS ID). At the will of the home base station manager, the CSG user and/or the non-CSG user can distinguish different levels, and the priority of the service is different, and the quality of the service and the service category can be different. By signing with the operator, the user can access the home base station corresponding to multiple closed user groups, for example, the user's office, home, and the like. The concept of allowing a closed user group list to be introduced is therefore introduced. This list is stored in the user's terminal and the user data server on the network side. There are three usage modes for home base stations: closed mode, mixed mode, and open mode. When the home base station is in the closed mode, only the CSG subscription user to which the home base station belongs can access the base station and enjoy the services provided by the base station. When the home base station is in the open mode, any operator subscription subscriber can access the base station, and the home base station at this time is equivalent to the macro base station. When the home base station is in the hybrid mode, any operator subscription or roaming user is also allowed to access, but different levels are classified according to whether the user subscribes to the CSG, that is, the user who signs the CSG is using the hybrid home. Base stations have higher service priorities and enjoy better quality of service and service categories. When the user performs initial access, the user data server on the network side sends the closed user group that the user subscribes to allow access to the mobility management entity of the core network. The core network mobility management entity will use this information to perform access control on the UE. If the UE accesses the core network from an unlicensed closed mode home base station, the core network will deny access to such users. The HeNB usually accesses the core network of the EPS through a leased fixed line. To ensure the security of the access, a security gateway (SeGW) is shielded in the core network. The data between the HeNB and the SeGW is encapsulated by IPSec. The HeNB can directly connect to the MME and the S-GW of the core network through the IPSec tunnel established by the HeNB and the SeGW, and can also connect to the MME and the S-GW through the HeNB GW. At the same time, in order to implement management of the HeNB, a Home eNodeB Management System (HeMS) is introduced. „ The QoS of the fixed line that is accessed by the HeNB is usually the owner of the HeNB and the fixed network operator. Therefore, when the 3GPP UE usually accesses the 3GPP core network access service, the required QoS cannot exceed the subscription QoS of the fixed network line that the fixed network operator can provide. Otherwise, the QoS of the UE access service There is no guarantee, especially Guaranteed Bitrate (GBR). Therefore, for 3GPP networks, the total QoS requirement for service access of all UEs accessed through the HeNB must not exceed that of the HeNB. QoS guarantee for fixed line subscription. jt匕, Universal Mobile Telecommunications System (UMTS) also supports access to home base station HNB (Home NodeB). Figure 4 is a non-roaming scenario according to the related art. Schematic diagram of the architecture of the HNB accessing the UMTS, and FIG. 5 is an architecture of the HNB accessing the UMTS in the home routing roaming scenario according to the related art. 6 is a schematic diagram of an architecture of an HNB accessing UMTS in a local grooming roaming scenario according to the related art. The architectures in FIG. 4, FIG. 5, and FIG. 6 are similar to the architectures of FIG. 1, FIG. 2, and FIG. 3, except that , using the Serving General packet radio service support node (SGSN) instead of the S-GW, using the gateway general packet radio service support node
( Gateway General Packet Radio Service Supporting Node, 简称为 GGSN ) 代 替了 P-GW。 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(Gateway General Packet Radio Service Supporting Node, GGSN for short) replaced P-GW. In the case where the home base station accesses through the contracted fixed line, it is necessary to consider a scenario in which multiple home base stations (for example, HeNB, HNB) access the 3GPP core network through a contracted fixed line. At this time, for the 3GPP network, all user equipments accessed through the multiple home base stations must be controlled.
( 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。 而在相关技术中, 共享同一个签约固网线路的不同用户设备通过一个或 多个家用基站接入时, 网络侧可能为各个用户设备选择不同的 PCRF, 这样, 就导致了在相关技术中, 无法控制共享同一签约固网线路但是选择了不同
PCRF的用户设备的总的业务访问 QoS需求不超过该签约固网线路的签约The total QoS requirement for service access (User Equipment, UE for short) does not exceed the subscription QoS guarantee of the same fixed line that the multiple home base stations access. In the related art, when different user equipments sharing the same fixed-line line are accessed by one or more home base stations, the network side may select different PCRFs for each user equipment, thus causing related technologies in the related art. Unable to control sharing the same contracted fixed line but chose different The total service access QoS requirement of the user equipment of the PCRF does not exceed the signing of the contracted fixed network line.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. In the following embodiments, the Interwork-Policy and Charing Rule Function (I-PCRF) is introduced. The PCRF will control the broadband policy in the fixed network through I-PCRF.
4匡架 BPCF ( Broadband Policy Control Framework ) 实现交互。 I-PCRF可以 独立部署在家用基站 (HeNB、 HNB )拥有者所归属的移动运营商网络中, 也可以作为 BPCF的功能增强, 部署在家用基站拥有者所租用固网线路所归
属的固网运营商的网络中。 对于同一个运营商网络, 可以部署多个 I-PCRF。 通过同一个家用基站或多个家用基站且该多个家用基站通过同一个签约固网 线路接入核心网的 3GPP UE 所建立的所有 IP-CAN会话的 QoS ·ί受权统一由 一个 I-PCRF向 BPCF请求。 (对于 I-PCRF为 BPCF功能增强的部署, 可以 理解为 PCRF向一个 BPCF请求 QoS授权)。 图 7是根据本发明实施例的授权请求方法的流程图, 如图 7所示, 该流 程包括如下步骤: 步骤 S702, UE通过家用基站 (例如, HeNB, HNB )请求建立 IP-CAN 会话, 其中, 该家用基站通过签约固网线路连接到 3GPP核心网; 步骤 S704, PCRF为 IP连接接入网会话( IP Connectivity Access Network, 简称为 IP-CAN )会话选择 I-PCRF , 其中, 为通过同一签约固网线路建立的 IP-CAN会话选择同一 I-PCRF; 步骤 S706, 该 PCRF请求选择出的 I-PCRF为该 IP-CAN会话进行 QoS 授权。 由于对于同一个 UE建立的 IP-CAN会话所选择的 PCRF可以是不一样 的, 而对于不同的 UE建立的 IP-CAN会话所选择的 PCRF也可以是不一样 的。 但是, 通过上述步骤 S702至步骤 S704, 由于在 IP-CAN会话建立过程 中, 向 PCRF上报的其所属的签约固网线路是相同的, 因此各个 PCRF将为 所有这些 IP-CAN选择同一个 I-PCRF。 其中, PCRF可以向 I-PCRF发送该签约固网线路的宽带连接信息。 PCRF 可以通过以下方式获得宽带连接信息: 4 truss BPCF (Broadband Policy Control Framework) implements interaction. The I-PCRF can be deployed independently in the mobile operator network to which the home base station (HeNB, HNB) owner belongs, or can be used as a function enhancement of the BPCF, and deployed in the fixed network line leased by the home base station owner. It belongs to the network of fixed network operators. Multiple I-PCRFs can be deployed for the same carrier network. QoS of all IP-CAN sessions established by 3GPP UEs accessing the core network through the same home base station or multiple home base stations and the multiple home base stations are connected by an I-PCRF BPCF request. (For the deployment of ICMPF for BPCF function enhancement, it can be understood that the PCRF requests QoS authorization from a BPCF). FIG. 7 is a flowchart of an authorization request method according to an embodiment of the present invention. As shown in FIG. 7, the process includes the following steps: Step S702: A UE requests to establish an IP-CAN session through a home base station (eg, HeNB, HNB), where The home base station is connected to the 3GPP core network through the contracted fixed network line; in step S704, the PCRF selects an I-PCRF for the IP Connectivity Access Network (IP-Access) network session (IP-CAN), wherein the same contract is adopted. The IP-CAN session established by the fixed line selects the same I-PCRF; step S706, the PCRF requests the selected I-PCRF to perform QoS authorization for the IP-CAN session. Since the PCRF selected for the IP-CAN session established by the same UE may be different, the PCRF selected for the IP-CAN session established by different UEs may also be different. However, through the above steps S702 to S704, since the affiliated fixed network lines to which the PCRF is reported are the same during the IP-CAN session establishment process, each PCRF will select the same I- for all of these IP-CANs. PCRF. The PCRF may send the broadband connection information of the subscription fixed network line to the I-PCRF. The PCRF can obtain broadband connection information in the following ways:
PCEF或 BBERF接收到请求建立 IP-CAN会话的消息, 其中, 该消息中 携带 IP-CAN会话建立所通过的签约固网线路的宽带连接信息; PCEF或 BBERF向 PCRF发送宽带连接信息。 优选地, PCRF还可以将 UE的 CSG信息上 4艮给 I-PCRF。 这样 I-PCRF 就可以获知该 UE接入的 HeNB的接入模式,以及该 UE与家用基站所属 CSG 的成员关系。当 BPCF根据签约固网线路当前的资源情况拒绝 I-PCRF的 QoS 请求后, I-PCRF将根据发起 QoS请求的 IP-CAN会话的 CSG信息和 /或用户
优先级等进行进一步的决策。 决定释放非 CSG用户或较低优先级用户的资 源, 以便分配给 CSG用户或较高优先级用户使用。 图 8、 图 9、 图 10分别为根据本发明实施例的 3GPP UE在非漫游场景、 家乡路由漫游场景和本地疏导漫游场景下的通过 HeNB接入的架构示意图。 图 11、 图 12、 图 13分别为根据本发明实施例的 3GPP UE在非漫游场景、 家 乡路由漫游场景和本地疏导漫游场景下的通过 HNB接入的架构示意图。 由于引入了 I-PCRF的功能网元, PCRF将通过 I-PCRF与 BPCF实现交 互。 该功能网元部署在家用基站 (HeNB、 HNB )拥有者所归属的运营商网 络中。 因此, 对于图 9、 图 10、 图 12和图 13的漫游场景, I-PCRF部署在拜 访网络。 对于同一个运营商网络中, 可以部署多个 I-PCRF。 由于接入同一个 家用基站、 或者接入多个家用基站但该多个家用基站共享固网签约线路的所 有 UE建立的 IP-CAN所选择的 PCRF (包括家乡 PCRF简称为 H-PCRF、 拜 访地 PCRF简称为 V-PCRF )有可能是不同的, 因此所有这些 PCRF将必须 通过同一个 I-PCRF与 BPCRF, 以便 I-PCRF才艮据签约固网线路当前的 QoS 状况, 对当前接入的所有 UE的业务访问进行 QoS控制。 对于图 9的架构中, 当 S-GW与 P-GW之间釆用通用隧道协议( General Tunnel Protocol, 简称为 GTP )协议时, H-PCRF直接与 I-PCRF交互, I-PCRF 进一步与 BPCF进行交互。 当 S-GW与 P-GW之间釆用 PMIPv6协议时, H-PCRF与 V-PCRF交互、而 V-PCRF与 I-PCRF交互, I-PCRF进一步与 BPCF 交互。 下面对在图 8至图 13的架构下的实施例进行分别说明。 实施例一 图 14是才艮据本发明实施例一的流程图, 图 14示出了基于图 8和图 11 的非漫游架构, UE建立 IP-CAN会话时, PCRF与 I-PCRF, I-PCRF与 BPCF 建立分别建立会话, 进行 QoS授权的过程。 其中, UE建立的 IP-CAN会话 没有 BBERF存在, 包括如下步骤: 步骤 S 1401: 在 UE请求建立 IP-CAN会话的过程中, PCEF收到请求建 立 IP-CAN会话消息, 该请求建立 IP-CAN会话消息中携带用户的用户标识、 请求接入的 PDN网络的 PDN标识, 宽带连接信息以及可选的 CSG信息等。 其中, 宽带连接信息可以是 HeNB连接的家庭网关 ( Residential GateWay ,
简称为 RGW )的公共 IP地址, 也可以是 RGW的线路标识, 也可以是 HeNB 拥有者与固网签约的用户名; 对于 UE通过 HeNB接入的过程, 该步骤中 PCEF获得的宽带连接信息 以及可选的 CSG信息的过程如下: 在 UE的附着流程中,UE向 HeNB发送附着请求消息, HeNB再向 MME 发送附着请求消息,并在该附着请求消息中携带宽带连接信息。如果该 HeNB 为闭合模式或混合模式, 在 HeNB还可以在消息中携带 CSG信息, CSG信 息中包括 CSG的接入模式和 CSG标识。 MME将与 HSS交互获得用户的签 约数据, 并根据其中的 CSG签约数据允许 UE接入; 随后 MME向 S-GW发 送创建会话请求消息,该创建会话请求消息中携带宽带连接信息以及 CSG信 息。如果该 HeNB和混合模式, 那么 MME还在 CSG信息中增加成员关系指 示, 该指示分为 CSG用户和非 CSG用户; S-GW再向 P-GW发送创建会话 请求消息, 该创建会话请求消息中携带宽带连接信息以及 CSG信息, 这样位 于 P-GW的 PCEF就获得了 UE当前接入的宽带连接信息以及可选的 CSG信 息。 或者, 在 UE建立另外的 PDN连接流程中 (即 UE在附着以后, 还建立 另外一个 PDN连接, 这时选择的 P-GW和附着时选择的 P-GW可能不同), UE向 MME发送 PDN连接请求, 之后 MME向 S-GW发送创建会话请求消 息, 该创建会话请求消息中携带宽带连接信息以及 CSG信息 ( CSG信息包 含的内容与附着流程中的一致)。 S-GW再向 P-GW发送创建会话请求消息, 该创建会话请求消息中携带宽带连接信息以及 CSG信息,这样位于 P-GW的 PCEF就获得了 UE当前接入的宽带连接信息以及可选的 CSG信息。 如果 HeNB是通过 HeNB GW接入核心网的, 那么上述流程中, HeNB 的宽带连接信息以及可选的 CSG信息将通过 HeNB GW转发给 MME, 其中 步骤相同。 对于 UE通过 HNB接入的过程,该步骤中 PCEF获得宽带连接信息以及 可选的 CSG信息具体过程与 HeNB类似: 宽带连接信息以及可选的 CSG信 息由 NodeB发送给 HNB GW, HNB GW再发送给 SGSN, 再由 SGSN发送 给 GGSN, 这样, 位于 GGSN的 PCEF就可获得宽带连接信息以及可选的 CSG信息。
步骤 S 1402: PCEF向 PCRF发送 IP-CAN会话建立指示消息,该 IP-CAN 会话建立指示消息中携带用户标识, PDN标识、为 UE分配的地址 IP Address 以及 PCEF所收到的宽带连接信息以及可选的 CSG信息等; 步骤 S 1403: 如果 PCRF没有相关的签约信息, 则 PCRF向 SPR发送签 约文档请求消息, 携带用户标识、 PDN标识; 步骤 S 1404: SPR返回签约信息; 步骤 S 1405: PCRF并根据签约数据、 网络策略、 接入信息等制定策略 PCC策略。该 PCC策略中包括以下至少之一:默认 PCC规则以及 APN-AMBR 等信息, 默认 PCC规则的 QoS信息中包括服务质量类型标识 QCI和分配保 持优先级 ARP参数。 其中 ARP参数可以标识用户的优先级; 步骤 S 1406: PCRF向 I-PCRF发送互通会话建立消息, 消息中携带宽带 连接信息、 可选的 CSG信息以及默认 PCC规则、 APN-AMBR; The PCEF or BBERF receives a message requesting to establish an IP-CAN session, where the message carries the broadband connection information of the subscribed fixed network line through which the IP-CAN session is established; the PCEF or BBERF sends the broadband connection information to the PCRF. Preferably, the PCRF may also send the CSG information of the UE to the I-PCRF. In this way, the I-PCRF can learn the access mode of the HeNB accessed by the UE, and the membership relationship between the UE and the CSG to which the home base station belongs. After the BPCF rejects the I-PCRF QoS request according to the current resource condition of the contracted fixed line, the I-PCRF will according to the CSG information and/or the user of the IP-CAN session that initiated the QoS request. Priority, etc. make further decisions. It is decided to release resources of non-CSG users or lower priority users for distribution to CSG users or higher priority users. FIG. 8, FIG. 9, and FIG. 10 are schematic diagrams showing the architecture of a 3GPP UE accessing through a HeNB in a non-roaming scenario, a home routing roaming scenario, and a local grooming roaming scenario, respectively, according to an embodiment of the present invention. FIG. 11 , FIG. 12 , and FIG. 13 are schematic diagrams showing the architecture of a 3GPP UE accessing through an HNB in a non-roaming scenario, a home routing roaming scenario, and a local grooming roaming scenario, respectively, according to an embodiment of the present invention. Due to the introduction of the functional network element of the I-PCRF, the PCRF will interact with the BPCF through the I-PCRF. The function network element is deployed in an operator network to which the owner of the home base station (HeNB, HNB) belongs. Thus, for the roaming scenarios of Figures 9, 10, 12, and 13, the I-PCRF is deployed on the visited network. Multiple I-PCRFs can be deployed in the same carrier network. The PCRF selected by the IP-CAN established by all the UEs that access the same home base station or access multiple home base stations but the multiple home base stations share the fixed network subscription line (including the home PCRF for short, H-PCRF, visited place) The PCRF is abbreviated as V-PCRF. It may be different, so all these PCRFs will have to pass the same I-PCRF and BPCRF, so that the I-PCRF will be based on the current QoS status of the contracted fixed line, for all currently accessed. The UE's service access performs QoS control. For the architecture of Figure 9, when the General Tunnel Protocol (GTP) protocol is used between the S-GW and the P-GW, the H-PCRF directly interacts with the I-PCRF, and the I-PCRF further interacts with the BPCF. Interact. When the PMIPv6 protocol is used between the S-GW and the P-GW, the H-PCRF interacts with the V-PCRF, and the V-PCRF interacts with the I-PCRF, and the I-PCRF further interacts with the BPCF. The embodiments under the architectures of Figs. 8 to 13 will be separately described below. Embodiment 1 FIG. 14 is a flowchart according to Embodiment 1 of the present invention, and FIG. 14 shows a non-roaming architecture based on FIG. 8 and FIG. 11, when a UE establishes an IP-CAN session, PCRF and I-PCRF, I- The PCRF establishes a session with the BPCF to establish a session and perform QoS authorization. The IP-CAN session established by the UE does not have a BBERF, and the method includes the following steps: Step S1401: During the UE requesting to establish an IP-CAN session, the PCEF receives a request to establish an IP-CAN session message, and the request establishes an IP-CAN. The session message carries the user ID of the user, the PDN identifier of the PDN network requesting access, the broadband connection information, and optional CSG information. The broadband connection information may be a home gateway connected by the HeNB (Residential GateWay, The public IP address of the RGW can also be the line identifier of the RGW, or the user name of the HeNB owner and the fixed network. For the process of the UE accessing through the HeNB, the broadband connection information obtained by the PCEF in this step and The process of the optional CSG information is as follows: In the attach procedure of the UE, the UE sends an attach request message to the HeNB, and the HeNB sends an attach request message to the MME, and carries the broadband connection information in the attach request message. If the HeNB is in the closed mode or the hybrid mode, the HeNB may also carry the CSG information in the message, where the CSG information includes the access mode and the CSG identifier of the CSG. The MME will interact with the HSS to obtain the subscription data of the user, and allow the UE to access according to the CSG subscription data. The MME then sends a Create Session Request message to the S-GW, where the Create Session Request message carries the broadband connection information and the CSG information. If the HeNB and the hybrid mode, the MME further adds a membership indication to the CSG information, the indication is divided into a CSG user and a non-CSG user; and the S-GW sends a create session request message to the P-GW, where the session request message is sent. The broadband connection information and the CSG information are carried, so that the PCEF located at the P-GW obtains the broadband connection information currently accessed by the UE and the optional CSG information. Or, in the process of establishing another PDN connection by the UE (that is, after the UE is attached, another PDN connection is also established, where the selected P-GW and the selected P-GW may be different), and the UE sends a PDN connection to the MME. After the request, the MME sends a Create Session Request message to the S-GW, where the Create Session Request message carries the broadband connection information and the CSG information (the content included in the CSG information is consistent with the attachment flow). The S-GW sends a Create Session Request message to the P-GW, where the Create Session Request message carries the broadband connection information and the CSG information, so that the PCEF located in the P-GW obtains the broadband connection information currently accessed by the UE and optionally CSG information. If the HeNB accesses the core network through the HeNB GW, the broadband connection information of the HeNB and the optional CSG information will be forwarded to the MME through the HeNB GW, where the steps are the same. For the process of the UE accessing through the HNB, the specific process of the PCEF obtaining the broadband connection information and the optional CSG information in this step is similar to that of the HeNB: the broadband connection information and the optional CSG information are sent by the NodeB to the HNB GW, and the HNB GW sends the information to the HNB GW. The SGSN is then sent by the SGSN to the GGSN, so that the PCEF located in the GGSN can obtain broadband connection information and optional CSG information. Step S1402: The PCEF sends an IP-CAN session establishment indication message to the PCRF, where the IP-CAN session establishment indication message carries the user identifier, the PDN identifier, the IP address assigned to the UE, and the broadband connection information received by the PCEF, and The selected CSG information and the like; Step S1403: If the PCRF has no related subscription information, the PCRF sends a subscription document request message to the SPR, carrying the user identifier and the PDN identifier; Step S1404: SPR returns the subscription information; Step S1405: PCRF Develop a policy PCC policy based on contract data, network policies, and access information. The PCC policy includes at least one of the following: a default PCC rule and an APN-AMBR. The QoS information of the default PCC rule includes a quality of service type identifier QCI and an allocation hold priority ARP parameter. The ARP parameter may identify the priority of the user; Step S 1406: The PCRF sends an interworking session setup message to the I-PCRF, where the message carries the broadband connection information, the optional CSG information, and the default PCC rule, APN-AMBR;
PCRF选择 I-PCRF可以釆用如下方法: 3GPP网络配置 I-PCRF以及与 固网运营商的对应关系在 PCRF上, 这样当 PCRF获取宽带连接信息后, 根 据配置信息选择正确地 I-PCRF。 步骤 S 1407: I-PCRF根据宽带连接信息判断需要交互的固网运营商, 并 且是否为相同的宽带连接信息已经为建立了与 BPCF的互通会话, 如果还没 有为该宽带连接信息建立宽带接入会话, 则 I-PCRF向该运营商的 BPCF发 送宽带会话建立消息, 并向 BPCF提供宽带连接信息; 否则执行步骤 S 1409; 步骤 S 1408: BPCF向 I-PCRF返回确认消息; 步骤 S 1409: I-PCRF向 PCRF返回确认消息; 步骤 S 1410: PCRF向 PCEF返回确认消息, 消息中携带默认的 PCC规 则、 APN-AMBR等信息; 步骤 S 1411 : PCEF所在网关返回应答建立 IP-CAN会话。 实施例二 图 15是根据本发明实施例二的流程图, 图 15示出了基于图 8的非漫游 架构, UE建立 IP-CAN ( IP-Connectivity Access Network, IP连接访问网络 )
会话时, PCRF与 I-PCRF, I-PCRF与 BPCF建立分别建立会话, 进行 QoS 授权的过程。 其中, UE建立的 IP-CAN会话有 BBERF存在, 包括如下步骤: 步骤 S 1501: 在 UE请求建立 IP-CAN会话的过程中, BBERF收到请求 建立 IP-CAN会话消息, 该请求建立 IP-CAN会话消息中携带用户的用户标 识、请求接入的 PDN网络的 PDN标识, 宽带连接信息以及可选的 CSG信息 等。 其中宽带连接信息可以是 HeNB连接的 RGW的公共 IP地址, 也可以是 RGW的线路标识, 也可以是 HeNB拥有者与固网签约的用户名; 对于 UE通过 HeNB接入的过程, 该步骤中 BBERF获得的宽带连接信 息以及可选的 CSG信息过程如下: 在 UE的附着流程中,UE向 HeNB发送附着请求消息, HeNB再向 MME 发送附着请求消息,并在该附着请求消息中携带宽带连接信息。如果该 HeNB 为闭合模式或混合模式, 在 HeNB还在消息中携带 CSG信息, CSG信息中 包括 CSG的接入模式和 CSG标识。 MME将与 HSS交互获得用户的签约数 据, 并根据其中的 CSG签约数据允许 UE接入; 随后 MME向 S-GW发送创 建会话请求消息, 该创建会话请求消息中携带宽带连接信息以及 CSG信息。 如果该 HeNB和混合模式, 那么 MME还在 CSG信息中增加成员关系指示, 该指示分为 CSG用户和非 CSG用户; 这样位于 S-GW的 BBERF就获得了 UE当前接入的宽带连接信息以及可选的 CSG信息。 或者, 在 UE建立另外的 PDN连接流程中 (即 UE在附着以后, 还建立 另外一个 PDN连接, 这时选择的 P-GW和附着时选择的 P-GW可能不同), UE向 MME发送 PDN连接请求, 之后 MME向 S-GW发送创建会话请求消 息, 该创建会话请求消息中携带宽带连接信息以及 CSG信息 ( CSG信息包 含的内容与附着流程中的一致)。 这样位于 S-GW的 BBERF就获得了 UE当 前接入的宽带连接信息以及可选的 CSG信息。 如果 HeNB是通过 HeNB GW接入核心网的, 那么上述流程中, HeNB 的宽带连接信息以及可选的 CSG信息将通过 HeNB GW转发给 MME, 其余 步骤相同。 步骤 S 1502: BBERF向 PCRF发送网关控制会话建立消息, 该 IP-CAN 会话建立指示消息中携带用户标识, PDN标识以及 BBERF所收到的宽带连 接信息以及可选的 CSG信息等;
步骤 S 1503: 如果 PCRF没有相关的签约信息, 则 PCRF向 SPR发送签 约文档请求消息, 携带用户标识、 PDN标识; 步骤 S 1504: SPR返回签约信息; 步骤 S 1505: PCRF并根据签约数据、 网络策略、 接入信息等制定策略 PCC策略。 策略中包括默认 PCC规则、 QoS规则以及 APN-AMBR等信息, 默认 PCC规则、 OoS规则的 QoS信息中包括 QCI和 ARP参数。 其中 ARP 参数可以标识用户的优先级; 步骤 S 1506: PCRF向 I-PCRF发送互通会话建立消息, 消息中携带宽带 连接信息、 可选的 CSG信息以及默认 PCC规则、 APN-AMBR; The PCRF selects the I-PCRF to use the following method: The 3GPP network configures the I-PCRF and the correspondence with the fixed network operator on the PCRF, so that when the PCRF obtains the broadband connection information, the correct I-PCRF is selected according to the configuration information. Step S1407: The I-PCRF determines, according to the broadband connection information, the fixed network operator that needs to interact, and whether the same broadband connection information has established an interworking session with the BPCF, if the broadband connection information has not been established for the broadband connection information. In the session, the I-PCRF sends a broadband session setup message to the BPCF of the operator, and provides broadband connection information to the BPCF; otherwise, step S1409 is performed; Step S1408: BPCF returns an acknowledgement message to the I-PCRF; Step S1409: I - The PCRF returns an acknowledgment message to the PCRF; Step S 1410: The PCRF returns an acknowledgment message to the PCEF, where the message carries the default PCC rule, APN-AMBR, etc.; Step S 1411: The gateway where the PCEF is located returns a response to establish an IP-CAN session. Embodiment 2 FIG. 15 is a flowchart according to Embodiment 2 of the present invention, and FIG. 15 shows a non-roaming architecture based on FIG. 8 , where an UE establishes an IP-CAN (IP-Connectivity Access Network). During the session, the PCRF and the I-PCRF, the I-PCRF and the BPCF establish a session to establish a session and perform QoS authorization. The IP-CAN session established by the UE has a BBERF, and the method includes the following steps: Step S1501: During the UE requesting to establish an IP-CAN session, the BBERF receives a request to establish an IP-CAN session message, and the request establishes an IP-CAN. The session message carries the user ID of the user, the PDN identifier of the PDN network requesting access, the broadband connection information, and optional CSG information. The broadband connection information may be a public IP address of the RGW to which the HeNB is connected, or may be a line identifier of the RGW, or may be a user name that the HeNB owner subscribes to the fixed network. For the process of the UE accessing through the HeNB, the BBERF in this step The obtained broadband connection information and the optional CSG information process are as follows: In the attach procedure of the UE, the UE sends an attach request message to the HeNB, and the HeNB sends an attach request message to the MME, and carries the broadband connection information in the attach request message. If the HeNB is in the closed mode or the hybrid mode, the HeNB also carries the CSG information in the message, where the CSG information includes the CSG access mode and the CSG identifier. The MME will interact with the HSS to obtain the subscription data of the user, and allow the UE to access according to the CSG subscription data. The MME then sends a Create Session Request message to the S-GW, where the Create Session Request message carries the broadband connection information and the CSG information. If the HeNB and the hybrid mode, the MME further adds a membership indication to the CSG information, and the indication is divided into a CSG user and a non-CSG user; thus, the BBERF located in the S-GW obtains the broadband connection information currently accessed by the UE and Selected CSG information. Or, in the process of establishing another PDN connection by the UE (that is, after the UE is attached, another PDN connection is also established, where the selected P-GW and the selected P-GW may be different), and the UE sends a PDN connection to the MME. After the request, the MME sends a Create Session Request message to the S-GW, where the Create Session Request message carries the broadband connection information and the CSG information (the content included in the CSG information is consistent with the attachment flow). The BBERF located in the S-GW thus obtains the broadband connection information currently accessed by the UE and the optional CSG information. If the HeNB accesses the core network through the HeNB GW, the broadband connection information of the HeNB and the optional CSG information will be forwarded to the MME through the HeNB GW, and the remaining steps are the same. Step S1502: The BBERF sends a gateway control session establishment message to the PCRF, where the IP-CAN session establishment indication message carries the user identifier, the PDN identifier, the broadband connection information received by the BBERF, and optional CSG information. Step S1503: If the PCRF has no related subscription information, the PCRF sends a subscription document request message to the SPR, carrying the user identifier and the PDN identifier. Step S1504: SPR returns the subscription information; Step S1505: PCRF and according to the subscription data and the network policy , access information, etc. to develop a policy PCC strategy.

Step S1814: The gateway where the PCEF is located returns a response to establish an IP-CAN session. Embodiment 6 FIG. 19 is a flowchart according to Embodiment 6 of the present invention, and FIG. 19 shows a local grooming roaming architecture based on FIG. 10, when a UE establishes an IP-CAN session, V-PCRF and I-PCRF, I-PCRF and BPCF establishes a process of establishing a session and performing QoS authorization. The IP-CAN session established by the UE does not exist as a BBERF. The specific steps of Figure 19 are similar to the steps of Figure 18. The main difference is that the PCEF is located in the visited network, and the P-GW where the PCEF is located allocates an IP address to the UE, and then passes the IP address to the H-PCRF through the V-PCRF. Establishing an IP-CAN session for other UEs accessing the same home base station (HeNB or HNB) or accessing other home base stations, but these home base stations access the same contracted fixed line as the home base station in the above embodiment. The establishment of the IP-CAN session of the UE can be implemented according to different network scenarios using the corresponding processes of FIG. 14 to FIG. In the prior art, only when the HeNB is in the mixed mode and the closed mode, the CSG information is reported to the P-GW and further reported to the PCRF, and in the open mode, not reported to the P-GW and the PCRF. In the embodiment of the present invention, when the PCRF only receives the broadband connection information and does not receive the CSG information, the PCRF may consider that the HeNB accessed by the UE is in an open mode. Similarly, the I-PCRF can also consider that the HeNB accessed by the UE is in an open mode. In the following embodiments, among the CSG information mentioned, the modes accessed by the HeNB include an open mode, a mixed mode, and a closed mode. In the flow of the first embodiment to the sixth embodiment, the broadband connection information is given to the PCRF via PCEF or BBERF. Since the home base station can register the broadband connection information when registering with the home base station management system (referred to as the home base station H(e)MS). Therefore, for a non-roaming scenario, the PCRF can obtain the broadband connection information by querying the H(e)MS. For the roaming scenario, the V-PCRF can obtain the broadband connection information by querying the H(e)MS. In another embodiment of the present invention, the I-PCRF receives the request identifier of the QoS information and/or QoS information of the PCRF; the I-PCRF requests the broadband policy control framework BPCF according to the request identifier of the QoS information and/or the QoS information. QoS authorization, where the QoS authorization request for the IP-CAN session established through the same contracted fixed line is from the same I-PCRF. Preferably, the PCRF may formulate or update the QoS information before the I-PCRF receives the QoS information of the PCRF and the request identifier of the /QoS information; the PCRF sends the QoS information and the indication information to the I-PCRF, where the indication information is used for Instructing the I-PCRF to process the bandwidth resource by at least one of the following: allocation, update, and QoS information includes: ARP and GBR. For resource release, the PCRF determines the bandwidth resource for releasing the authorized QoS information; the PCRF sends an identifier and indication information for determining the QoS of the released bandwidth resource to the I-PCRF, where the indication information is used to indicate the I-PCRF release bandwidth. Resources. If the BCPF sends a message rejecting the allocation or updating of the bandwidth resource, the I-PCRF determines whether the QoS information can preempt the resources allocated by the fixed-line line for other QoS information at least one of the following: The closed user group CSG information obtained by the PCRF, ARP in QoS information.
I-PCRF指示 BPCF释放被抢占的其他 QoS信息的带宽资源; 在 BPCF 释放资源之后, I-PCRF再次指示 BCPF分配或增加与第一次请求分配或增加 的带宽资源大小相同的带宽资源; BPCF分配或增加带宽资源, 并返回接受 消息。 优选地, I-PCRF向 PCRF发送消息, 其中, 消息中携带被抢占的其他 QoS信息的请求标识; PCRF向 BBERF和 /或 PCEF发送消息, 请求删除或 去激活 QoS信息的请求标识对应的策略规则; 或者, PCRF更新 QoS信息的 请求标识对应的策略规则, 并将更新后的策略规则发送给 BBERF和 /或 PCEF。 下面实施例是上述实施例的变型实施例, 下面对此分别进行说明。 实施例七 本实施例描述的是按照图 14或图 15的流程建立 IP-CAN会话的某个 UE 因访问业务而需要请求、 修改或释放 QoS资源的过程中, PCRF、 I-PCRF和 BPCF交互的¾¾程。 图 20是才艮据本发明实施例七的流程图, 该流程包括如下步骤: 步骤 S2001 : PCRF收到 AF提供的业务信息或是 UE发起的资源修改请 求消息后进行策略决策。 决策包括以下 3种:
( a )如果 AF提供新的业务信息或 UE发起新的资源分配请求,则 PCRF 进行 QoS授权为制定 PCC规则,以及 QoS规则(釆用图 15流程建立的 IP-CAN 会话)。该 PCC规则或 QoS规则的 QoS信息中包含 QCI、 ARP、 GBR和 MBR。 The I-PCRF instructs the BPCF to release the bandwidth resources of the preempted other QoS information; after the BPCF releases the resource, the I-PCRF again instructs the BCPF to allocate or increase the bandwidth resource of the same size as the first request allocated or increased bandwidth resource; BPCF allocation Or increase the bandwidth resource and return an accept message. Preferably, the I-PCRF sends a message to the PCRF, where the message carries the request identifier of the preempted other QoS information; the PCRF sends a message to the BBERF and/or the PCEF, requesting to delete or deactivate the policy rule corresponding to the request identifier of the QoS information. Alternatively, the PCRF updates the QoS information request identifier corresponding to the policy rule, and sends the updated policy rule to the BBERF and/or PCEF. The following embodiment is a modified embodiment of the above embodiment, which will be separately described below. Embodiment 7 This embodiment describes a process in which a UE that establishes an IP-CAN session according to the flow of FIG. 14 or FIG. 15 needs to request, modify, or release QoS resources due to accessing a service, and the PCRF, the I-PCRF, and the BPCF interact. 3⁄43⁄4 steps. FIG. 20 is a flowchart of Embodiment 7 of the present invention. The process includes the following steps: Step S2001: The PCRF performs policy decision after receiving the service information provided by the AF or the resource modification request message initiated by the UE. The decision includes the following three types: (a) If the AF provides new service information or the UE initiates a new resource allocation request, the PCRF performs QoS authorization for the development of PCC rules, as well as QoS rules (IP-CAN sessions established using the process of Figure 15). The QoS information of the PCC rule or the QoS rule includes QCI, ARP, GBR, and MBR.
( b )如果 AF通知业务终止或 UE发起资源释放请求, 则 PCRF进行的 QoS授权为删除或去激活对应的 PCC规则, 以及 QoS规则 (釆用图 15流程 建立的 IP-CAN会话)。该要删除或去激活 PCC规则或 QoS规则的 QoS信息 中包含 QCI、 ARP, GBR和 MBR。 (b) If the AF notification service terminates or the UE initiates a resource release request, the QoS authorization by the PCRF is to delete or deactivate the corresponding PCC rule, and the QoS rule (the IP-CAN session established by the process of Figure 15). The QoS information of the PCC rule or QoS rule to be deleted or deactivated includes QCI, ARP, GBR and MBR.
( c )如果 AF修改已提供的业务信息或 UE请求修改已分配的资源, 那 么 PCRF的 QoS授权为更新已制定的 PCC规则, 以及 QoS规则 (釆用图 15 流程建立的 IP-CAN会话)。该 PCC规则或 QoS规则的 QoS信息中包含 QCI、 ARP, GBR和 MBR。 步骤 S2002: PCRF向 I-PCRF发送互通会话 QoS请求消息,请求 I-PCRF(c) If the AF modifies the provided service information or the UE requests to modify the allocated resources, then the PCRF's QoS authorization is to update the established PCC rules, as well as the QoS rules (using the IP-CAN session established by the process of Figure 15). The QoS information of the PCC rule or QoS rule includes QCI, ARP, GBR and MBR. Step S2002: The PCRF sends an interworking session QoS request message to the I-PCRF, requesting the I-PCRF
QoS授权。 如果 PCRF决策为 ( a ), 则 PCRF向 I-PCRF请求分配新的资源, PCRF 在消息中携带请求分配新的资源的指示, 新制定 PCC规则中的 QoS信息, 以及给该 QoS信息分配的一个 QoS请求标识。其中 QoS信息中至少包括 ARP 和 GBR。 ARP表示该 QoS信息的优先级, GBR表示请求 I-PCRF分配的带 宽资源 GBR, QoS请求标识用于标识该请求的 QoS信息; 如果 PCRF决策为 ( b ), 则 PCRF向 I-PCRF请求释放已分配的资源。 PCRF在消息中携带请求释放资源的指示, 以及要删除或去激活 PCC规则对 应的 QoS信息的标识 (即在该 PCC规则新制定时, PCRF向 I-PCRF请求分 配资源时, 为该 QoS信息分配的 QoS请求标识) 以通知 I-PCRF需要释放 QoS请求标识标识的 QoS信息的资源; 如果 PCRF决策为 ( c ), 则 PCRF向 I-PCRF请求更新已分配的资源。 PCRF在消息中携带请求更新资源指示,更新后 PCC规则中的 QoS信息和已 分配的 QoS请求标识 (即在该 PCC规则新制定时, PCRF向 I-PCRF请求分 配资源时, 为该 QoS信息分配的 QoS请求标识;), 以通知 I-PCRF需要更新 QoS请求标识标识的 QoS信息的资源;; 步骤 S2003: I-PCRF向 BPCF发送宽带会话 QoS请求消息,请求 BPCF QoS授权。
如果 I-PCRF收到的消息为请求分配资源,, 那么 I-PCRF在消息中携带 请求分配新的资源的指示以及 QoS信息中的 GBR, 以请求 BPCF分配带宽 资源 GBR; 如果 I-PCRF收到的消息为请求释放资源,, 则 I-PCRF在消息中携带请 求释放资源的指示以及 QoS信息中的 GBR, 以请求 BPCF释放带宽资源 GBR; 如果 I-PCRF收到的消息为请求更新资源,, 那么 I-PCRF将才艮据更新的 QoS信息中的 GBR与已分配 GBR的增量来向 BPCF请求, 如果更新后的 GBR减小了,则 I-PCRF在消息中携带的 GBR为 GBR的增量,并请求 BPCF 释放带宽资源 GBR增量; 如果更新后的 GBR增加了, 则 I-PCRF在消息中 携带 GBR为 GBR增量, 并请求 BPCF分配带宽资源 GBR增量; 步骤 S2004: BPCF才艮据 I-PCRF的请求消息, 执行相应的策略。 如果 BPCF接收到请求分配带宽资源 GBR, BPCF根据签约固网线路当 前可用带宽情况进行资源接纳。如果剩余的可用带宽大于等于 GBR,则 BPCF 接收 I-PCRF的请求, 并向 I-PCRF返回接收确认消息, 同时 BPCF将从签约 固网线路当前可用带宽中扣除 GBR;如果剩余的可用带宽小于 GBR,则 BPCF 拒绝 I-PCRF的请求, 并向 I-PCRF返回拒绝消息, 并在中携带 BPCF能够接 受的带宽; 如果 BPCF接收到请求释放带宽资源 GBR, 则 BPCF直接返回接收确认 消息, 同时 BPCF将在签约固网线路当前可用带宽中增加 GBR。 步骤 S2005: I-PCRF才艮据 BPCF返回消息进行策略决策。 如果 I-PCRF接收到是接收确认消息 (包括接收资源分配和资源释放), 则执行步 4聚 S2009; 如果 I-PCRF接收到是拒绝消息, 那么 I-PCRF将才艮据 QoS信息中的优 先级 ARP以及发起该 QoS请求的 UE的 CSG信息执行以下逻辑判断: QoS authorization. If the PCRF decision is (a), the PCRF requests the I-PCRF to allocate a new resource, and the PCRF carries an indication in the message requesting allocation of a new resource, newly formulated QoS information in the PCC rule, and a one assigned to the QoS information. QoS request identifier. The QoS information includes at least ARP and GBR. ARP indicates the priority of the QoS information, GBR indicates the bandwidth resource GBR requested by the I-PCRF, and the QoS request identifier is used to identify the QoS information of the request. If the PCRF decision is (b), the PCRF requests the release from the I-PCRF. Allocated resources. The PCRF carries an indication of requesting release of the resource, and an identifier of the QoS information corresponding to the PCC rule to be deleted or deactivated (that is, when the PCRF requests the resource allocation to the I-PCRF when the PCC rule is newly formulated, the QoS information is allocated. QoS request identifier) to inform the I-PCRF that the resource of the QoS information identified by the QoS request identifier needs to be released; if the PCRF decision is (c), the PCRF requests the I-PCRF to update the allocated resource. The PCRF carries the request update resource indication in the message, the QoS information in the updated PCC rule, and the allocated QoS request identifier (that is, when the PCRF requests the resource allocation to the I-PCRF when the PCC rule is newly formulated, the QoS information is allocated. QoS request identifier;), to inform the I-PCRF that the resource of the QoS information identified by the QoS request identifier needs to be updated; Step S2003: The I-PCRF sends a broadband session QoS request message to the BPCF requesting the BPCF QoS authorization. If the message received by the I-PCRF allocates a resource for the request, the I-PCRF carries an indication of requesting allocation of a new resource and a GBR in the QoS information in the message to request the BPCF to allocate the bandwidth resource GBR; if the I-PCRF receives The message is a request to release the resource, and the I-PCRF carries an indication of requesting release of the resource and a GBR in the QoS information in the message to request the BPCF to release the bandwidth resource GBR; if the message received by the I-PCRF is to request to update the resource, Then, the I-PCRF will request the BPCF according to the GBR in the updated QoS information and the increment of the allocated GBR. If the updated GBR is reduced, the GBR carried by the I-PCRF in the message is an increase of the GBR. And request the BPCF to release the bandwidth resource GBR increment; if the updated GBR is increased, the I-PCRF carries the GBR as the GBR increment in the message, and requests the BPCF to allocate the bandwidth resource GBR increment; Step S2004: BPCF According to the request message of the I-PCRF, the corresponding policy is executed. If the BPCF receives the request to allocate the bandwidth resource GBR, the BPCF performs resource admission according to the currently available bandwidth of the contracted fixed line. If the remaining available bandwidth is greater than or equal to GBR, the BPCF receives the I-PCRF request and returns a reception confirmation message to the I-PCRF, and the BPCF will deduct the GBR from the currently available bandwidth of the subscription fixed line; if the remaining available bandwidth is less than the GBR The BPCF rejects the I-PCRF request and returns a reject message to the I-PCRF, and carries the bandwidth that the BPCF can accept; if the BPCF receives the request to release the bandwidth resource GBR, the BPCF directly returns a receive acknowledgement message, and the BPCF will Add GBR to the currently available bandwidth of the contracted fixed line. Step S2005: The I-PCRF performs policy decision according to the BPCF return message. If the I-PCRF receives the reception confirmation message (including the reception resource allocation and the resource release), step 4 is performed; if the I-PCRF receives the rejection message, the I-PCRF will prioritize the priority in the QoS information. The level ARP and the CSG information of the UE that initiated the QoS request perform the following logical decisions:
( a )如果 CSG信息中的接入模式是混合模式, 并且发起该 QoS请求的 UE的成员关系为非 CSG用户,
( al )如果存在有该用户自己已经授权的其他 QoS信息或通过同一个签 约固网线路接入的其他非 CSG用户的已经授权的其他 QoS信息,那么 I-PCRF 根据 QoS信息中的 ARP将该 QoS与其他 QoS信息进行比较, 如果该 QoS 信息无法抢占其他的 QoS信息, 则执行步骤 S2014。 如果该 QoS信息可以抢 占其他 QoS信息的资源, 则执行步骤 S2006; (a) if the access mode in the CSG information is a hybrid mode, and the membership of the UE that initiated the QoS request is a non-CSG user, (al) If there are other QoS information that the user has authorized himself or other authorized QoS information of other non-CSG users accessing through the same contracted fixed line, the I-PCRF will refer to the ARP according to the ARP in the QoS information. The QoS is compared with other QoS information. If the QoS information cannot preempt other QoS information, step S2014 is performed. If the QoS information can preempt resources of other QoS information, step S2006 is performed;
( a2 )如果不存在有该用户自己已经 ·ί受权的其他 QoS信息或通过同一个 签约固网线路接入的其他非 CSG用户的已经 ·ί受权的 QoS信息, 则执行步骤 S2014。 (a2) If there is no other QoS information that the user himself/herself has authorized or the QoS information of other non-CSG users accessing through the same contracted fixed line, step S2014 is performed.

( bl )如果存在有通过同一个签约固网线路接入的其他非 CSG用户的已 经 QoS授权的其他 QoS信息, 则该 QoS信息将抢占其他已经 QoS授权的 QoS信息; ( bl ) if there are other QoS information that has been QoS-authorized by other non-CSG users accessing through the same contracted fixed line, the QoS information will preempt other QoS information already authorized by QoS;
( b2 ) 如果不存在其他非 CSG用户的已经 QoS授权的 QoS信息, 那么 I-PCRF根据 ARP将该 QoS信息与该用户自己已经 QoS ·ί受权的其他 QoS信 息以及通过同一个签约固网线路接入的所有其他 CSG用户的已经 ·ί受权的 QoS信息进行比较, 如果该 QoS信息无法抢占其他的 QoS信息, 则执行步 骤 S2014。 如果该 QoS信息可以抢占其他 CSG用户已经授权的 QoS信息资 源, 则执行步骤 S2006; (b2) If there is no QoS information already QoS-authorized by other non-CSG users, then the I-PCRF associates the QoS information with other QoS information that the user has already QoS-accepted according to the ARP and through the same contracted fixed line. If the QoS information of all other CSG users that have entered is compared, if the QoS information cannot preempt other QoS information, step S2014 is performed. If the QoS information can preempt the QoS information resources that have been authorized by other CSG users, step S2006 is performed;
( c )如果 CSG信息中的接入的模式为开放模式或闭合模式,那么 I-PCRF 根据 ARP将该 QoS信息与该用户自己已经 QoS授权的其他 QoS信息以及通 过同一个签约固网线路接入的所有其他用户的已经 ·ί受权的 QoS信息进行比 较, 如果该 QoS信息无法抢占其他的 QoS信息, 则执行步骤 S2014。 如果该 QoS信息可以抢占其他用户已经授权的 QoS信息的资源,则执行步骤 S2006。 步骤 S2006: 执行图 23、 图 24或图 25的流程。 执行该步骤后, 签约固 网线路的剩余可用带宽将大于等于该 QoS信息中的 GBR。 步骤 S2007: I-PCRF再次向 BPCF发送宽带会话 QoS请求消息, 携带步 骤 S2002中的请求分配的带宽 GBR。 步骤 S2008: BPCF分配资源, 向 I-PCRF返回接受确认消息。
步骤 S2009: I-PCRF向 PCRF返回确认消息, 携带接受指示。 步骤 S2010:如果釆用图 14流程建立的 IP-CAN会话,则 PCRF向 BBERF 发送网关控制和 QoS规则提供消息。 如果 PCRF决策为 ( a ), 则 PCRF在消息中携带新制定 QoS规则信息; 如果 PCRF决策为 ( b ), 则 PCRF在消息中携带要删除或去激活 QoS规 则信息; 如果 PCRF决策为 ( c ), 则 PCRF在消息中携带更新后 QoS规则信息。 步骤 S2011 : 如果釆用图 15流程建立的 IP-CAN会话, 则 BBERF执行 QoS规则, 并向 PCRF返回确认消息。 步骤 S2012: PCRF向 PCEF发送策略计费规则提供消息。 如果 PCRF决策为 ( a ) , 则 PCRF在消息中携带新制定 PCC规则信息; 如果 PCRF决策为( b ), 则 PCRF在消息中携带要删除或去激活 PCC规 则信息; 如果 PCRF决策为 ( c ) , 则 PCRF在消息中携带更新后 PCC规则信息。 步骤 S2013: PCEF向 PCRF返回确认消息, 流程结束。 步骤 S2014: I-PCRF向 PCRF返回确认消息, 携带拒绝指示。 PCRF才艮 据拒绝指示, 向 AF或者 UE返回 QoS ·ί受权拒绝消息, 流程结束。 对于按照图 16的流程建立 IP-CAN会话的某个 UE因访问业务而需要请 求、 4爹改、 或释放 QoS资源的过程中, H-PCRF、 I-PCRF和 BPCF交互的流 程与图 20的流程一致。 实施例八 本实施例描述的是按照图 17的流程建立 IP-CAN会话的某个 UE因访问 业务而需要请求、 修改、 或释放 QoS资源的过程中, PCRF (包括 H-PCRF、 V-PCRF ), I-PCRF和 BPCF交互的流程。 图 21是才艮据本发明实施例八的流程图, 该流程包括如下步骤:
步骤 S2101 : H-PCRF收到 AF提供的业务信息或是 UE发起的资源修改 请求消息后进行策略决策。 决策包括以下 3种: (c) If the mode of access in the CSG information is open mode or closed mode, the I-PCRF accesses the QoS information according to the ARP with other QoS information authorized by the user himself and through the same contracted fixed line. If all the other users' QoS information is compared, if the QoS information cannot preempt other QoS information, step S2014 is performed. If the QoS information can preempt the resources of the QoS information that the other user has authorized, step S2006 is performed. Step S2006: The flow of FIG. 23, FIG. 24 or FIG. 25 is performed. After performing this step, the remaining available bandwidth of the contracted fixed line will be greater than or equal to the GBR in the QoS information. Step S2007: The I-PCRF sends a broadband session QoS request message to the BPCF again, carrying the bandwidth GBR of the request allocation in step S2002. Step S2008: The BPCF allocates a resource and returns an acceptance confirmation message to the I-PCRF. Step S2009: The I-PCRF returns an acknowledgement message to the PCRF, carrying an acceptance indication. Step S2010: If the IP-CAN session established by the flow of FIG. 14 is used, the PCRF sends a gateway control and QoS rule providing message to the BBERF. If the PCRF decision is (a), the PCRF carries the newly formulated QoS rule information in the message; if the PCRF decision is (b), the PCRF carries the QoS rule information to be deleted or deactivated in the message; if the PCRF decision is (c) Then, the PCRF carries the updated QoS rule information in the message. Step S2011: If the IP-CAN session established by the flow of FIG. 15 is used, the BBERF executes the QoS rule and returns an acknowledgement message to the PCRF. Step S2012: The PCRF sends a policy charging rule providing message to the PCEF. If the PCRF decision is (a), the PCRF carries the newly formulated PCC rule information in the message; if the PCRF decision is (b), the PCRF carries the PCC rule information to be deleted or deactivated in the message; if the PCRF decision is (c) Then, the PCRF carries the updated PCC rule information in the message. Step S2013: The PCEF returns an acknowledgement message to the PCRF, and the flow ends. Step S2014: The I-PCRF returns an acknowledgement message to the PCRF, carrying a rejection indication. The PCRF returns the QoS ί 受 受 受 ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί The process of interaction between H-PCRF, I-PCRF and BPCF in the process of requesting, tampering, or releasing QoS resources for a UE that establishes an IP-CAN session according to the flow of FIG. 16 and FIG. 20 The process is consistent. Embodiment 8 This embodiment describes a PCRF (including H-PCRF, V-PCRF) in a process in which a certain UE that establishes an IP-CAN session according to the procedure of FIG. 17 needs to request, modify, or release QoS resources due to accessing a service. ), the process of interaction between I-PCRF and BPCF. Figure 21 is a flow chart according to Embodiment 8 of the present invention, the flow comprising the following steps: Step S2101: The H-PCRF performs policy decision after receiving the service information provided by the AF or the resource modification request message initiated by the UE. The decision includes the following three types:
( a ) 如果 AF提供新的业务信息或 UE发起新的资源分配请求, 则 H-PCRF进行 QoS授权为制定 PCC规则, 以及 QoS规则。 该 PCC规则或 QoS规则的 QoS信息中包含 QCI、 ARP、 GBR和 MBR。 (a) If the AF provides new service information or the UE initiates a new resource allocation request, the H-PCRF performs QoS authorization for the development of PCC rules, as well as QoS rules. The QoS information of the PCC rule or QoS rule includes QCI, ARP, GBR, and MBR.
( b )如果 AF通知业务终止或 UE发起资源释放请求, 则 H-PCRF进行 QoS授权为, 决定删除或去激活对应的 PCC规则, 以及 QoS规则。 该要删 除或去激活 PCC规则或 QoS规则的 QoS信息中包含 QCI、 ARP、 GBR和 MBR。 (b) If the AF notification service is terminated or the UE initiates a resource release request, the H-PCRF performs QoS authorization to decide to delete or deactivate the corresponding PCC rule, and the QoS rule. The QoS information to be deleted or deactivated for PCC rules or QoS rules includes QCI, ARP, GBR, and MBR.
( c )如果 AF修改已提供的业务信息或 UE请求修改已分配的资源, 那 么 H-PCRF进行 QoS授权为,更新已制定的 PCC规则, 以及 QoS规则。 该 PCC规则或 QoS规则的 QoS信息中包含 QCI、 ARP、 GBR和 MBR。 步骤 S2102: H-PCRF向 V-PCRF发送 S9会话规则提供消息,根据 H-PCRF 决策的不同, 携带新制定 QoS规则, 或删除或去激活的 QoS规则或更新后 的 QoS规则。 步骤 S2103 : V-PCRF向 I-PCRF发送互通会话 QoS请求消息,请求 I-PCRF 的 QoS授权。 如果 H-PCRF决策为 ( a ), 则 V-PCRF向 I-PCRF请求分配新的资源, V-PCRF在消息中携带请求分配新的资源的指示, 新制定 QoS规则中的 QoS 信息, 以及给该 QoS信息分配的一个 QoS请求标识。 其中 QoS信息中至少 包括 ARP和 GBR。 ARP表示该 QoS信息的优先级, GBR表示请求 I-PCRF 分配的带宽资源 GBR, QoS请求标识用于标识该请求的 QoS信息; 如果 H-PCRF决策为 ( b ), 则 V-PCRF向 I-PCRF请求释放已分配的资 源。 V-PCRF在消息中携带请求释放资源的指示, 以及要删除或去激活 QoS 规则对应的 QoS信息的标识(即在该 QoS规则新制定时, V-PCRF向 I-PCRF 请求分配资源时, 为该 QoS信息分配的 QoS请求标识)以通知 I-PCRF需要 释放 QoS请求标识标识的 QoS信息的资源; 如果 H-PCRF决策为 ( c ), 则 V-PCRF向 I-PCRF请求更新已分配的资 源。 V-PCRF在消息中携带请求更新资源指示, 更新后 QoS规则中的 QoS信
息和已分配的 QoS请求标识(即在该 QoS规则新制定时, V-PCRF向 I-PCRF 请求分配资源时, 为该 QoS信息分配的 QoS请求标识;), 以通知 I-PCRF需 要更新 QoS请求标识标识的 QoS信息的资源; 步骤 S2104: I-PCRF向 BPCF发送宽带会话 QoS请求消息, 请求 BPCF 的 QoS授权。 如果 I-PCRF收到的消息为请求分配资源, 那么 I-PCRF在消息中携带请 求分配资源的指示以及 QoS信息中的 GBR, 以请求 BPCF分配带宽资源 GBR; 如果 I-PCRF收到的消息为请求释放资源, 则 I-PCRF在消息中携带请求 释放资源的指示以及 QoS信息中的 GBR,以请求 BPCF释放带宽资源 GBR; 如果 I-PCRF收到的消息为请求更新资源, 那么 I-PCRF将才艮据更新的 QoS信息中的 GBR与已分配 GBR的增量来向 BPCF请求, 如果更新后的 GBR减小了, 则 I-PCRF在消息中携带的 GBR为 GBR的增量, 并携带请求 释放资源的指示; 如果更新后的 GBR增加了, 则 I-PCRF在消息中携带 GBR 为 GBR增量, 并携带请求分配资源的指示; 步骤 S2105: BPCF才艮据 I-PCRF的请求消息, 执行相应的策略。 如果 BPCF接收到请求分配带宽资源 GBR, BPCF根据签约固网线路当 前可用带宽情况进行资源接纳。如果剩余的可用带宽大于等于 GBR,则 BPCF 接收 I-PCRF的请求, 并向 I-PCRF返回接收确认消息, 同时 BPCF将从签约 固网线路当前可用带宽中扣除 GBR;如果剩余的可用带宽小于 GBR,则 BPCF 拒绝 I-PCRF的请求, 并向 I-PCRF返回拒绝消息, 并在消息中携带 BPCF能 够接受的带宽; 如果 BPCF接受到请求释放带宽资源 GBR, 则 BPCF直接返回接收确认 消息, 同时 BPCF将在签约固网线路当前可用带宽中增加 GBR。 步骤 S2106: I-PCRF才艮据 BPCF返回消息进行策略决策。 如果 I-PCRF接收到是接收确认消息 (包括接收资源分配和资源释放), 则执行步 4聚 S2110;
如果 I-PCRF接收到是拒绝消息, 那么 I-PCRF将才艮据 QoS信息的优先 级 ARP和发起该 QoS请求的 UE的 CSG信息执行以下逻辑判断: (c) If the AF modifies the provided service information or the UE requests to modify the allocated resources, the H-PCRF performs QoS authorization to update the established PCC rules, and QoS rules. The QoS information of the PCC rule or the QoS rule includes QCI, ARP, GBR, and MBR. Step S2102: The H-PCRF sends an S9 session rule providing message to the V-PCRF, and carries a newly formulated QoS rule, or a deleted or deactivated QoS rule or an updated QoS rule according to different H-PCRF decisions. Step S2103: The V-PCRF sends an interworking session QoS request message to the I-PCRF, requesting QoS authorization of the I-PCRF. If the H-PCRF decision is (a), the V-PCRF requests the I-PCRF to allocate a new resource, and the V-PCRF carries an indication requesting to allocate a new resource in the message, newly formulates the QoS information in the QoS rule, and gives A QoS request identifier assigned by the QoS information. The QoS information includes at least ARP and GBR. ARP indicates the priority of the QoS information, GBR indicates the bandwidth resource GBR requested by the I-PCRF, and the QoS request identifier is used to identify the QoS information of the request. If the H-PCRF decision is (b), the V-PCRF is directed to I- The PCRF requests to release the allocated resources. The V-PCRF carries an indication of requesting release of the resource, and an identifier of the QoS information corresponding to the QoS rule to be deleted or deactivated (ie, when the V-PCRF requests the allocation of resources to the I-PCRF when the QoS rule is newly formulated, The QoS request identifier of the QoS information is allocated to notify the I-PCRF that the resource of the QoS information identified by the QoS request identifier needs to be released; if the H-PCRF decision is (c), the V-PCRF requests the I-PCRF to update the allocated resource. . The V-PCRF carries the request update resource indication in the message, and the QoS information in the updated QoS rule Information and the assigned QoS request identifier (that is, the QoS request identifier assigned to the QoS information when the V-PCRF requests the I-PCRF to allocate resources when the QoS rule is newly formulated); to notify the I-PCRF that the QoS needs to be updated. Requesting resources identifying the identified QoS information; Step S2104: The I-PCRF sends a Broadband Session QoS Request message to the BPCF requesting QoS authorization of the BPCF. If the message received by the I-PCRF allocates a resource for the request, the I-PCRF carries an indication of the resource allocation request and the GBR in the QoS information to request the BPCF to allocate the bandwidth resource GBR; if the message received by the I-PCRF is Requesting to release the resource, the I-PCRF carries an indication of requesting release of the resource and GBR in the QoS information in the message to request the BPCF to release the bandwidth resource GBR; if the message received by the I-PCRF is to request to update the resource, then the I-PCRF will According to the GBR in the updated QoS information and the increment of the allocated GBR, the request is made to the BPCF. If the updated GBR is reduced, the GBR carried in the message by the I-PCRF is the GBR increment and carries the request. If the updated GBR is increased, the I-PCRF carries the GBR as a GBR increment in the message, and carries an indication requesting to allocate the resource; Step S2105: The BPCF performs the request message according to the I-PCRF, and executes The corresponding strategy. If the BPCF receives the request to allocate the bandwidth resource GBR, the BPCF performs resource admission according to the currently available bandwidth of the contracted fixed line. If the remaining available bandwidth is greater than or equal to GBR, the BPCF receives the I-PCRF request and returns a reception confirmation message to the I-PCRF, and the BPCF will deduct the GBR from the currently available bandwidth of the subscription fixed line; if the remaining available bandwidth is less than the GBR The BPCF rejects the I-PCRF request and returns a reject message to the I-PCRF, and carries the bandwidth that the BPCF can accept in the message; if the BPCF accepts the request to release the bandwidth resource GBR, the BPCF directly returns a receive acknowledgement message, and the BPCF GBR will be added to the currently available bandwidth of the contracted fixed line. Step S2106: The I-PCRF performs policy decision according to the BPCF return message. If the I-PCRF receives a reception confirmation message (including receiving resource allocation and resource release), step 4 is performed S2110; If the I-PCRF receives the reject message, the I-PCRF will perform the following logical decision based on the priority ARP of the QoS information and the CSG information of the UE that initiated the QoS request:
( a )如果 CSG信息中的接入模式是混合模式, 并且发起该 QoS请求的 UE的成员关系为非 CSG用户: (a) If the access mode in the CSG information is in a hybrid mode, and the membership of the UE initiating the QoS request is a non-CSG user:
( al ) 如果存在有该用户自己已经 QoS ·ί受权的其他 QoS信息或通过同 一个签约固网线路接入的其他非 CSG用户的已经 QoS授权的 QoS信息, 那 么 I-PCRF根据 ARP将该 QoS信息与其他已经授权的 QoS信息进行比较, 如果该 QoS信息无法抢占其他的 QoS信息, 则执行步骤 S2116。 如果该 QoS 信息可以抢占其他 QoS信息的资源, 则执行步骤 S2107; ( al ) If there is other QoS information that the user has QoS ί 受 or other QoS-authorized QoS information of other non-CSG users accessing through the same contracted fixed line, then the I-PCRF QoS according to ARP The information is compared with other authorized QoS information. If the QoS information cannot preempt other QoS information, step S2116 is performed. If the QoS information can preempt the resources of other QoS information, step S2107 is performed;
( a2 ) 如果不存在有该用户自己已经 QoS ·ί受权的其他 QoS信息或其他 非 CSG用户的已经 QoS ·ί受权的其他 QoS信息, 则执行步骤 S2116。 ( a2 ) If there is no other QoS information that the user has already QoS ί or other QoS information that is not QoS ί authorized by the user, step S2116 is performed.
( b )如果 CSG信息中的接入模式时混合模式, 并且发起该 QoS请求的 UE的成员关系为 CSG用户: (b) If the access mode in the CSG information is mixed mode, and the membership of the UE that initiated the QoS request is a CSG user:
( bl )如果存在有通过同一个签约固网线路接入的其他非 CSG用户的已 经 QoS授权的 QoS信息,在该 QoS信息将抢占其他非 CSG用户的已经 QoS 授权的 QoS信息, ( bl ) if there is QoS-authorized QoS information of other non-CSG users accessing through the same contracted fixed line, the QoS information will preempt QoS information of other non-CSG users with QoS authorization,
( b2 )如果不存在有通过同一个签约固网线路接入的其他非 CSG用户的 已经 QoS授权的 QoS信息, 那么 I-PCRF根据 ARP将该 QoS规则与该用户 自己已经 QoS ·ί受权的其他 QoS信息或所有其他 CSG用户的已经 ·ί受权的 QoS 信息进行比较, 如果该 QoS规则无法抢占其他的 QoS规则, 则执行步骤 S2116。 如果该 QoS信息可以抢占其他 CS G用户已经授权的 QoS信息的资 源, 则执行步骤 S2107; (b2) If there is no QoS information already QoS-authorized by other non-CSG users accessing through the same contracted fixed line, then the I-PCRF modifies the QoS rule according to the ARP with the user's own QoS. The QoS information is compared with the already-authorized QoS information of all other CSG users. If the QoS rule cannot preempt other QoS rules, step S2116 is performed. If the QoS information can preempt the resources of the QoS information that the other CS G user has authorized, step S2107 is performed;

实施例九 本实施例描述的是按照图 18或图 19的流程建立 IP-CAN会话的某个 UE 因访问业务而需要请求、 修改、 或释放 QoS资源的过程中, PCRF (包括 H-PCRF, V-PCRF ), I-PCRF和 BPCF交互的流程。 图 22是才艮据本发明实施例九的流程图, 该流程包括如下步骤: 步骤 S2201 : H-PCRF收到 AF提供的业务信息或是 UE发起的资源修改 请求消息后进行策略决策。 决策包括以下 3种: (c) If the mode of access in the CSG information is open mode or closed mode, the I-PCRF accesses the QoS information according to the ARP with other QoS information authorized by the user himself and through the same contracted fixed line. The QoS information of all other users is compared, and if the QoS information cannot preempt other QoS information, step S2116 is performed. If the QoS information can preempt the resources of the QoS information that the other user has authorized, step S2107 is performed. Step S2107: The flow of FIG. 23, FIG. 24 or FIG. 25 is executed. After performing this step, the remaining available bandwidth of the contracted fixed line will be greater than or equal to the GBR in the QoS information. Step S2108: The I-PCRF sends a broadband session QoS request message to the BPCF again, carrying the bandwidth GBR of the request allocation in step S2103. Step S2109: The BPCF allocates a resource and returns an acceptance confirmation message to the I-PCRF. Step S2110: The I-PCRF returns an acknowledgement message to the V-PCRF, carrying an acceptance indication. Step S2111: The V-PCRF returns an S9 session rule providing confirmation message to the H-PCRF, and notifies the H-PCRF to request acceptance. Step S2112: The V-PCRF sends a gateway control and QoS rule providing message to the BBERF. If the H-PCRF decision is (a), the PCRF carries the newly formulated QoS rule information in the message; if the H-PCRF decision is (b), the PCRF carries the QoS rule information to be deleted or deactivated in the message; The PCRF decision is (c), and the PCRF carries the updated QoS rule information in the message. Step S2113: Then the BBERF executes the QoS rule and returns an acknowledgement message to the PCRF. Step S2114: The H-PCRF sends a policy charging rule providing message to the PCEF. If the H-PCRF decision is (a), the H-PCRF carries the newly formulated PCC rule information in the message; if the H-PCRF decision is (b), the H-PCRF carries the information to delete or deactivate the PCC rule in the message. If the H-PCRF decision is (c), the H-PCRF carries the updated PCC rule information in the message. Step S2115: The PCEF returns an acknowledgement message to the H-PCRF, and the process ends. Step S2116: The I-PCRF returns an acknowledgement message to the V-PCRF, carrying a rejection indication. Step S2117: The V-PCRF returns an acknowledgement message to the H-PCRF, notifying that the H-PCRF request is rejected. The H-PCRF returns the QoS to the AF or the UE according to the rejection indication, and the process ends. Embodiment 9 This embodiment describes a process in which a UE that establishes an IP-CAN session according to the process of FIG. 18 or FIG. 19 needs to request, modify, or release QoS resources due to accessing a service, and the PCRF (including H-PCRF, V-PCRF), the flow of interaction between I-PCRF and BPCF. FIG. 22 is a flowchart of Embodiment 9 of the present invention. The process includes the following steps: Step S2201: The H-PCRF performs policy decision after receiving the service information provided by the AF or the resource modification request message initiated by the UE. The decision includes the following three types:
( a ) 如果 AF提供新的业务信息或 UE发起新的资源分配请求, 则 H-PCRF进行的 QoS授权, 制定 PCC规则。 该 PCC规则的 QoS信息中包含 QCK ARP、 GBR和 MBR。 (a) If the AF provides new service information or the UE initiates a new resource allocation request, the QoS authorization by the H-PCRF establishes a PCC rule. The QoS information of the PCC rule includes QCK ARP, GBR, and MBR.
( b )如果 AF通知业务终止或 UE发起资源释放请求, 则 H-PCRF进行 QoS ·ί受权, 决定删除或去激活对应的 PCC规则。 该要删除或去激活 PCC规 则的 QoS信息中包含 QCI、 ARP、 GBR和 MBR。 (b) If the AF notification service is terminated or the UE initiates a resource release request, the H-PCRF performs QoS ί authorization to delete or deactivate the corresponding PCC rule. The QoS information to delete or deactivate the PCC rules includes QCI, ARP, GBR, and MBR.
( c )如果 AF修改已提供的业务信息或 UE请求修改已分配的资源, 那 么 H-PCRF进行 QoS授权, 更新已制定的 PCC规则。 该 PCC规则的 QoS信 息中包含 QCI、 ARP、 GBR和 MBR。 步骤 S2202: H-PCRF向 V-PCRF发送 S9会话规则提供消息。 如果 H-PCRF决策为( a ), 则 H-PCRF在消息中携带新制定 PCC规则信 息; 如果 H-PCRF决策为( b ),则 H-PCRF在消息中携带要删除或去激活 PCC 规则信息; 如果 H-PCRF决策为( c ), 则 H-PCRF在消息中携带更新后 PCC规则信 息。 步骤 S2203: V-PCRF向 I-PCRF发送互通会话 QoS请求消息,请求 I-PCRF 的 QoS授权。 如果 H-PCRF决策为 ( a ), 则 V-PCRF向 I-PCRF请求分配新的资源, V-PCRF在消息中携带请求分配新的资源的指示, 新制定 PCC规则中的 QoS
信息, 以及给该 QoS信息分配的一个 QoS请求标识。 其中 QoS信息中至少 包括 ARP和 GBR。 ARP表示该 QoS信息的优先级, GBR表示请求 I-PCRF 分配的带宽资源 GBR, QoS请求标识用于标识该请求的 QoS信息; 如果 H-PCRF决策为 ( b ), 则 V-PCRF向 I-PCRF请求释放已分配的资 源。 V-PCRF在消息中携带请求释放资源的指示, 以及要删除或去激活 PCC 规则对应的 QoS信息的标识(即在该 PCC规则新制定时, V-PCRF向 I-PCRF 请求分配资源时, 为该 QoS信息分配的 QoS请求标识)以通知 I-PCRF需要 释放 QoS请求标识标识的 QoS信息的资源; 如果 H-PCRF决策为 ( c ), 则 V-PCRF向 I-PCRF请求更新已分配的资 源。 V-PCRF在消息中携带请求更新资源指示, 更新后 PCC规则中的 QoS信 息和已分配的 QoS请求标识(即在该 PCC规则新制定时, V-PCRF向 I-PCRF 请求分配资源时, 为该 QoS信息分配的 QoS请求标识;), 以通知 I-PCRF需 要更新 QoS请求标识标识的 QoS信息的资源;。 步骤 S2204: I-PCRF向 BPCF发送宽带会话 QoS请求消息, 请求 BPCF 的 QoS授权。 如果 I-PCRF收到的消息为请求分配资源, 那么 I-PCRF在消息中携带请 求分配资源的指示以及 QoS信息中的 GBR, 以请求 BPCF分配带宽资源 GBR; 如果 I-PCRF收到的消息为请求释放资源, 则 I-PCRF在消息中携带请求 释放资源的指示以及 QoS信息中的 GBR,以请求 BPCF释放带宽资源 GBR; 如果 I-PCRF收到的消息为请求更新资源,, 那么 I-PCRF将才艮据更新的 QoS信息中的 GBR与已分配 GBR的增量来向 BPCF请求, 如果更新后的 GBR减小了, 则 I-PCRF在消息中携带的 GBR为 GBR的增量, 并携带请求 释放资源的指示; 如果更新后的 GBR增加了, 则 I-PCRF在消息中携带 GBR 为 GBR增量, 并携带请求分配资源的指示; 步骤 S2205: BPCF才艮据 I-PCRF的请求消息, 执行相应的策略。 如果 BPCF接受到请求分配带宽资源 GBR, BPCF根据签约固网线路当 前可用带宽情况进行资源接纳。如果剩余的可用带宽大于等于 GBR,则 BPCF 接收 I-PCRF的请求, 并向 I-PCRF返回接收确认消息, 同时 BPCF将从签约
固网线路当前可用带宽中扣除 GBR;如果剩余的可用带宽小于 GBR,则 BPCF 拒绝 I-PCRF的请求, 并向 I-PCRF返回拒绝消息, 并消息中携带 BPCF能够 接受的带宽; 如果 BPCF接受到请求释放带宽资源 GBR, 则 BPCF直接返回接收确认 消息, 同时 BPCF将在签约固网线路当前可用带宽中增加 GBR。 步骤 S2206: I-PCRF才艮据 BPCF返回消息进行策略决策。 如果 I-PCRF接收到是接收确认消息 (包括接收资源分配和资源释放), 则执行步 4聚 S2210; 如果 I-PCRF接收到是拒绝消息, 那么 I-PCRF将才艮据 QoS信息的 ARP 和发起该 QoS请求的 UE的 CSG信息执行以下逻辑判断: (c) If the AF modifies the provided service information or the UE requests to modify the allocated resources, the H-PCRF performs QoS authorization and updates the established PCC rules. The QoS information of the PCC rule includes QCI, ARP, GBR, and MBR. Step S2202: The H-PCRF sends an S9 session rule providing message to the V-PCRF. If the H-PCRF decision is (a), the H-PCRF carries the newly formulated PCC rule information in the message; if the H-PCRF decision is (b), the H-PCRF carries the information to delete or deactivate the PCC rule in the message. If the H-PCRF decision is (c), the H-PCRF carries the updated PCC rule information in the message. Step S2203: The V-PCRF sends an interworking session QoS request message to the I-PCRF, requesting QoS authorization of the I-PCRF. If the H-PCRF decision is (a), the V-PCRF requests the I-PCRF to allocate a new resource, and the V-PCRF carries an indication requesting to allocate a new resource in the message, and newly establishes the QoS in the PCC rule. Information, and a QoS request identifier assigned to the QoS information. The QoS information includes at least ARP and GBR. ARP indicates the priority of the QoS information, GBR indicates the bandwidth resource GBR requested by the I-PCRF, and the QoS request identifier is used to identify the QoS information of the request. If the H-PCRF decision is (b), the V-PCRF is directed to I- The PCRF requests to release the allocated resources. The V-PCRF carries an indication of requesting release of the resource, and an identifier of the QoS information corresponding to the PCC rule to be deleted or deactivated (ie, when the V-PCRF requests the allocation of resources to the I-PCRF when the PCC rule is newly formulated, The QoS request identifier of the QoS information is allocated to notify the I-PCRF that the resource of the QoS information identified by the QoS request identifier needs to be released; if the H-PCRF decision is (c), the V-PCRF requests the I-PCRF to update the allocated resource. . The V-PCRF carries the request update resource indication, the QoS information in the updated PCC rule, and the allocated QoS request identifier in the message (that is, when the V-PCRF requests the I-PCRF to allocate resources when the PCC rule is newly formulated, The QoS request identifier of the QoS information is allocated;) to notify the I-PCRF that the resource of the QoS information identified by the QoS request identifier needs to be updated; Step S2204: The I-PCRF sends a broadband session QoS request message to the BPCF, requesting QoS authorization of the BPCF. If the message received by the I-PCRF allocates a resource for the request, the I-PCRF carries an indication of the resource allocation request and the GBR in the QoS information to request the BPCF to allocate the bandwidth resource GBR; if the message received by the I-PCRF is If the request is to release the resource, the I-PCRF carries an indication of requesting release of the resource and a GBR in the QoS information to request the BPCF to release the bandwidth resource GBR. If the message received by the I-PCRF is to request to update the resource, then the I-PCRF The request to the BPCF is based on the GBR in the updated QoS information and the increment of the allocated GBR. If the updated GBR is reduced, the GBR carried in the message by the I-PCRF is the GBR increment and carries The request to release the resource; if the updated GBR is increased, the I-PCRF carries the GBR as a GBR increment in the message, and carries an indication requesting to allocate the resource; Step S2205: The BPCF responds to the request message of the I-PCRF, Implement the appropriate strategy. If the BPCF accepts the request to allocate the bandwidth resource GBR, the BPCF performs resource admission according to the current available bandwidth of the contracted fixed line. If the remaining available bandwidth is greater than or equal to GBR, the BPCF receives the I-PCRF request and returns a reception confirmation message to the I-PCRF, and the BPCF will sign the contract. The GBR is deducted from the currently available bandwidth of the fixed line; if the remaining available bandwidth is less than the GBR, the BPCF rejects the I-PCRF request and returns a reject message to the I-PCRF, and the message carries the bandwidth that the BPCF can accept; if the BPCF accepts If the bandwidth resource GBR is requested to be released, the BPCF directly returns a reception confirmation message, and the BPCF will add GBR to the currently available bandwidth of the subscription fixed line. Step S2206: The I-PCRF performs policy decision according to the BPCF return message. If the I-PCRF receives the reception confirmation message (including the reception resource allocation and the resource release), step S4210 is performed; if the I-PCRF receives the rejection message, the I-PCRF will calculate the ARP and the QoS information. The CSG information of the UE that initiated the QoS request performs the following logical judgment:
( a )如果 CSG信息中的接入模式是混合模式, 并且发起该 QoS请求的 UE的成员关系为非 CSG用户: (a) If the access mode in the CSG information is in a hybrid mode, and the membership of the UE initiating the QoS request is a non-CSG user:
( al ) 如果存在有该用户自己已经 QoS ·ί受权的其他 QoS信息或通过同 一个签约固网线路接入的其他非 CSG用户的已经 QoS授权的 QoS信息, 那 么 I-PCRF根据 ARP将该 QoS信息与所有非 CSG用户的已经 ·ί受权的 QoS信 息进行比较,如果该 QoS信息无法抢占其他的 PCC规则,则执行步骤 S2216。 如果该 PCC规则可以抢占其他 QoS信息的资源, 则执行步骤 S2207; ( al ) If there is other QoS information that the user has QoS ί 受 or other QoS-authorized QoS information of other non-CSG users accessing through the same contracted fixed line, then the I-PCRF QoS according to ARP The information is compared with the already-authorized QoS information of all non-CSG users. If the QoS information cannot preempt other PCC rules, step S2216 is performed. If the PCC rule can preempt the resources of other QoS information, step S2207 is performed;
( a2 ) 如果不存在有该用户自己已经 QoS ·ί受权的其他 QoS信息或通过 同一个签约固网线路接入的其他非 CSG用户的已经 QoS授权的 QoS信息, 则执行步 4聚 S2216。 (a2) If there is no other QoS information that the user has already QoS ί or QoS information that has been QoS-authorized by other non-CSG users accessing the same fixed-line line, then step S2216 is performed.
( b )如果 CSG信息中的接入模式时混合模式, 并且发起该 QoS请求的 UE的成员关系为 CSG用户: (b) If the access mode in the CSG information is mixed mode, and the membership of the UE that initiated the QoS request is a CSG user:
( bl )如果存在有通过同一个签约固网线路接入的其他非 CSG用户的已 经 QoS授权的 QoS信息,在该 PCC规则将抢占其他非 CSG用户的已经 QoS 授权的 QoS信息的资源, ( bl ) if there is QoS-authorized QoS information of other non-CSG users accessing through the same contracted fixed line, the PCC rules will preempt the resources of the QoS-authorized QoS information of other non-CSG users.
( b2 ) 如果不存在其他非 CSG用户的已经 QoS授权的 QoS信息, 那么 I-PCRF根据 ARP将该 QoS信息与该用户自己已经 QoS ·ί受权的其他 QoS信 息以及通过同一个签约固网线路接入的所有 CSG用户的已经 ·ί受权的 QoS信
息进行比较, 如果该 QoS信息无法抢占其他的 QoS信息的资源, 则执行步 骤 S2216。 如果该 QoS信息可以抢占其他 CSG用户已经授权的 QoS信息的 资源, 则执行步骤 S2207; (b2) If there is no QoS information already QoS-authorized by other non-CSG users, then the I-PCRF associates the QoS information with other QoS information that the user has already QoS-accepted according to the ARP and through the same contracted fixed line. Authenticated QoS letter of all CSG users If the QoS information cannot preempt other resources of the QoS information, step S2216 is performed. If the QoS information can preempt the resources of the QoS information that the other CSG users have authorized, step S2207 is performed;
( c )如果 CSG信息中的接入的模式为开放模式或闭合模式,那么 I-PCRF 根据 ARP将该 QoS信息与该用户自己已经 QoS授权的其他 QoS信息以及通 过同一个签约固网线路接入的所有其他用户的已经 ·ί受权的 QoS信息进行比 较, 如果该 QoS信息无法抢占其他的 QoS信息的资源, 则执行步骤 S2216。 如果该 QoS信息可以抢占其他用户已经 ·ί受权的 QoS信息的资源, 则执行步 骤 S2207; 步骤 S2207: 执行图 23、 图 24或图 25的流程。 执行该步骤后, 签约固 网线路的剩余可用带宽将大于等于该 QoS信息中的 GBR。 步骤 S2208: I-PCRF再次向 BPCF发送宽带会话 QoS请求消息, 携带步 骤 S2203中的请求分配的带宽 GBR。 步骤 S2209: BPCF分配资源, 向 I-PCRF返回接受确认消息。 步骤 S2210: I-PCRF向 V-PCRF返回确认消息, 携带接受指示。 步骤 S2211 : V-PCRF向 H-PCRF返回 S9会话规则提供确认消息, 通知 H-PCRF请求接受。 步骤 S2212:如果釆用图 18流程建立的 IP-CAN会话,V-PCRF向 BBERF 发送网关控制和 QoS规则提供消息, 如果 H-PCRF决策为 ( a ), 则 V-PCRF根据 PCC规则制定 QoS规则, 并在消息中携带新制定 QoS规则信息; 如果 H-PCRF决策为( b ),则 V-PCRF在消息中携带要删除或去激活 PCC 规则对应的 QoS规则信息; 如果 H-PCRF决策为 ( c ), 则 V-PCRF根据更新的 PCC规则制定更新 QoS规则, 并在消息中携带更新后 QoS规则信息。 步骤 S2213: 如果釆用图 18流程建立的 IP-CAN会话, 则 BBERF执行 QoS规则, 并向 PCRF返回确认消息。
