Description

基于多接入技术的策略计费控制方法、 装置和系统 技术领域 本发明涉及通信领域， 具体而言， 涉及一种基于多接入技术的策略计费 控制方法、 装置和系统。 背景技术 第三代合作伙伴计划（ 3rd Generation Partnership Project, 筒称为 3GPP ) 演进的分组系统 （Evolved Packet System , 筒称为 EPS ) 包括如下网元： 演 进的通用移动通信系统陆地无线接入网 （Evolved Universal Terrestrial Radio Access Network, 筒称为 E-UTRAN )、 移动管理单元 （ Mobility Management Entity, 筒称为 MME )、 月 务网关 （ Serving Gateway , 筒称为 S-GW )、 分组 数据网络网关（ Packet Data Network Gateway, 筒称为 P-GW或者 PDN GW)、 归属用户月 务器 （ Home Subscriber Server, 筒称为 HSS )、 3GPP的认证 4受权 计费 ( Authentication、 Authorization and Accounting , 筒称为 AAA )月^务器， 策略和计费规则功能 ( Policy and Charging Rules Function, 筒称为 PCRF ) 实 体及其他支撑节点。 图 1是根据相关技术 EPS的系统架构示意图， 如图 1所示， MME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, 筒称为 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； PCRF是策略和计费规则功能实 体， 它通过接收接口 Rx和运营商网络十办议 ( Internet Protocol, 筒称为 IP ) 业务网络相连， 获取业务信息， 此外， 它通过 Gx/Gxa/Gxc接口与网络中的 网关设备相连， 负责发起 IP承载的建立 , 保证业务数据的服务质量（ Quality of Service, 筒称为 QoS ), 并进行计费控制。
EPS 支持与非 3GPP 系统的互通， 其中， 与非 3GPP 系统的互通通过 S2a/b/c接口实现， P-GW作为 3GPP与非 3GPP系统间的锚点。 在 EPS的系 统架构图中，非 3GPP系统被分为可信任非 3GPP IP接入和不可信任非 3GPP IP接入。 可信任非 3GPP IP接入可直接通过 S2a接口与 P-GW连接； 不可信 任非 3GPP IP接入需经过演进的分组数据网关（ Evolved Packet Data Gateway, 筒称为 ePDG ) 与 P-GW相连， ePDG与 P-GW间的接口为 S2b, S2c提供了 用户设备 ( User Equipment , 筒称为 UE )与 P-GW之间的用户面 目关的控制 和移动性支持， 其支持的移动性管理 ¼、议为支持双栈的移动 IPv6 ( Moblie Internet Protocol Version 6 Support for Dual Stack Hosts and Routers , 筒称为 DSMIPv6 )。 在 EPS 系统之中， 策略和计费执行功能 ( Policy and Charging Enforcement Function, 筒称为 PCEF ) 实体存在于 P-GW中， PCRF与 P-GW 之间 Gx接口 （见图 1 ) 交换信息。 当 P-GW与 S-GW间的接口基于 PMIPv6 时 , S-GW也具有|c载绑定和事件 4艮告功能（ Bearer Binding and Event Report Function, 筒称为 BBERF )实体对业务数据流进行 QoS控制 , S-GW与 PCRF 之间通过 Gxc接口 （见图 1 ) 交换信息。 当通过可信任非 3GPP接入系统接 入时， 可信任非 3GPP接入网关中也驻留 BBERF。 可信任非 3GPP接入网关 与 PCRF之间通过 Gxa接口 （见图 1 ) 交换信息。 当 UE漫游时， S9接口作 为归属地 PCRF和拜访地 PCRF的接口 , 同时， 为 UE提供业务的应用功能 ( Application Function, 筒称为 AF ), 通过 Rx接口向 PCRF发送用于制定策 略和计费控制 （Policy and Charging Control, 筒称为 PCC )策略的业务信息。 在 3GPP中， 通过接入点名称 （ Access Point Name, 筒称为 APN ) 可以找到 对应的 PDN网络。通常^ 1 UE到 PDN网络的一个连接称为一个 IP连接接入 网 （IP Connectivity Access Network, 筒称为 IP-CAN )会话。 在建立 IP-CAN 会话的过程中， BBERF和 PCEF分别与 PCRF之间建立 Diameter会话， 通 过这些 Diameter会话来传送对这个 IP-CAN会话进行控制的策略计费信息和 用于制定策略的信息等。
EPS支持 UE同时通过多个接入网接入一个 PDN, 即 ,多接入 ( Multiple Access )。 图 2是根据相关技术的多接入场景的示意图， 如图 2所示， UE同 时在非 3GPP和 3GPP接入的覆盖下，通过非 3GPP IP接入网和 3GPP接入网 通过同一个 P-GW接入到 PDN。 在这种场景下 , P-GW为 UE分配一个 IP地 址， 即， UE和 PDN之间只有一个 IP-CAN会话。 这样， UE请求的不同业 务的数据流可以在适合它传输的接入网中传输。 例如， 非 3GPP接入网是无 线保真 （Wireless Fidelity, 筒称为 WiFi ) 时， 超文本传输协议 ( Hypertext Transfer Protocol, 筒称为 HTTP ) 和文件传输十办议 ( File Transfer Protocol, 筒称为 FTP ) 的业务数据流就可以通过 WiFi接入网， 与此同时， 网络电话
(Voice over Internet Protocol, 筒称为 VoIP ) 的业务数据流就可以通过 3GPP 发送给 UE。 这样 , 对于 HTTP和 FTP这种实时性要求较低的业务可以发挥 WiFi 资费较低的优势， 而对于 VoIP 这种实时性要求较高的业务可以发挥 3GPP的 QoS控制 , 移动性管理较好的优势。 在网络传输业务数据流的过程中， 需要才艮据业务相应的 QoS属性为其 预留相应的资源。 在相关技术中， 可以有两种预留资源的方法，一种是由 UE 发起的预留资源请求， 另一种是由网络发起的预留资源请求。 其中， 在多接 入的场景下， 对于 UE发起的预留资源请求， 由 UE决定在哪个接入网络传 送业务数据流并请求网络预留资源； 但是， 对于由网络发起的资源预留， 如 何在合适的接入网进行资源预留 , 目前尚未提出有效的解决方案。 发明内容 针对目前当 UE同时通过多个接入网接入时， 网络无法根据业务在合适 的接入网连接中发起资源预留过程的问题而提出本发明， 为此， 本发明的主 要目的在于提供一种改进的策略计费控制方案， 以解决上述问题至少之一。 为了实现上述目的 , 根据本发明的一个方面， 提供了一种基于多接入技 术的策略计费控制方法。 才艮据本发明的基于多接入技术的策略计费控制方法包括：策略计费执行 功能实体确定业务数据流传输的接入网连接， 并将确定的接入网连接通知给 策略和计费规则功能实体。 优选地，在策略计费执行功能实体将确定的接入网连接通知给策略和计 费规则功能实体之后， 上述方法还包括： 策略和计费规则功能实体将相应的 服务质量规则发送给接入网连接中的承载绑定和事件报告功能实体， 以使承 载绑定和事件报告功能实体根据服务质量规则发起资源预留或资源释放过 程。 优选地，策略计费执行功能实体根据配置信息或网络策略确定业务数据 流传输的接入网连接。 优选地 ,策略计费执行功能实体将确定的接入网连接通知给策略和计费 规则功能实体包括： 策略计费执行功能实体将绑定指示发送给策略和计费规 则功能实体， 其中， 绑定指示中携带有唯一区分接入网连接的信息。 优选地， 在建立网络协议连接接入网会话时， 策略计费执行功能实体通 过网络协议连接接入网会话建立指示消息将绑定指示发送给策略和计费规则 功能实体。 优选地， 在建立网络协议连接接入网会话后， 策略计费执行功能实体通 过网络协议连接接入网会话修改指示消息、 策略计费规则确认消息或策略计 费规则请求消息将绑定指示发送给策略和计费规则功能实体。 优选地，接入网连接通过以下信息之一来唯一标识： 网络协议连接接入 网类型和 /或无线接入技术类型、 用于指示接入网连接的网络协议地址。 为了实现上述目的， 根据本发明的另一个方面， 提供了一种策略计费执 行功能实体。 根据本发明的策略计费执行功能实体包括： 确定模块， 用于根据配置信 息确定业务数据流传输的接入网连接； 通知模块， 用于将确定模块确定的接 入网连接信息通知给策略和计费规则功能实体。 为了实现上述目的， 才艮据本发明的再一个方面， 提供了一种基于多接入 技术的策略计费控制系统。 才艮据本发明的基于多接入技术的策略计费控制系统包括策略计费执行 功能实体和策略和计费规则功能实体， 其中， 策略计费执行功能实体包括： 确定模块， 用于确定业务数据流传输的接入网连接； 通知模块， 用于将确定 模块确定的接入网连接通知给策略和计费规则功能实体； 策略和计费规则功 能实体包括： 接收模块， 用于接收来自策略计费执行功能实体的接入网连接 的信息； 发送模块， 用于根据接收模块接收的接入网连接的信息将相应的服 务质量规则发送给接入网连接中的承载绑定和事件报告功能实体， 以使承载 绑定和事件报告功能实体根据服务质量规则发起资源预留或资源释放过程。 通过本发明， 采用 PCEF 决定业务数据流传输的接入网连接并通知 PCRF 的方法， 解决了目前当 UE 同时通过多个接入网接入时， 网络无法才艮 据业务在合适的接入网中发起资源预留过程的问题， 进而实现了当 UE同时 通过多个接入网接入时， 网络可以根据业务在合适的接入网中发起资源预留 过程。 附图说明 此处所说明的附图用来提供对本发明的进一步理解 ,构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中： 图 1是根据相关技术的 EPS的系统架构的示意图； 图 2是根据相关技术的多接入场景的示意图； 图 3是根据相关技术的多接入过程的流程图； 图 4 是根据本发明实施例一的基于多接入技术的接入处理方法的流程 图； 图 5 是根据本发明实施例二的基于多接入技术的接入处理方法的流程 图； 图 6 是根据本发明实施例三的基于多接入技术的接入处理方法的流程 图； 图 7是才艮据本发明实施例的策略计费执行功能实体的结构框图； 图 8 是根据本发明实施例的基于多接入技术的策略计费控制系统的结 构框图。 具体实施方式 功能相克述 考虑到目前当 UE同时通过多个接入网接入时， 网关无法根据业务在合 适的接入网中发起资源预留过程的问题， 本发明实施例提供了一种多接入场 景下网络发起资源预留的方案， PCEF 决定业务数据流传输的接入网连接并 通知 PCRF , PCRF ^)夺相应的 QoS规则发送至该接入网连接中的 BBERF , 该 BBERF安装 QoS规则， 并根据 QoS规则在接入网中发起资源预留过程。 为了便于对本发明实施例的理解，下面对本发明实施例涉及的相关技术 的多接入过程进行描述。 图 3是根据相关技术的多接入过程的流程图， 如图 3所示，描述的是当 UE处于 3GPP接入网和可信任非 3GPP接入网的双覆盖 范围内后， UE 同时通过 3GPP接入网和可信任非 3GPP接入网建立到默认 PDN的连接的流程。 其中， 通过 3GPP接入时， S-GW和 P-GW之间采用 ΡΜΙΡνό协议 ,通过可信任非 3GPP接入时 ,可信任非 3GPP接入网管与 P-GW 之间采用 ΡΜΙΡν6协议。 该多接入过程具体包括以下的步骤 301至步骤 323: 步骤 301 , UE发送附着请求消息给 MME。 步骤 302 , MME发起对 UE的认证流程， 才艮据需要在 MME与 HSS之 间交换认证相关信息； 在认证成功之后， MME发起位置更新流程， HSS UE的签约数据发送给 MME。 在认证过程中， HSS将 P-GW的选择信息发送 给 MME, 其中， 选择信息包括默认 APN。 MME才艮据 APN选择 P-GW, 同 时， MME选择 S-GW。 步骤 303 , MME向 S-GW发送默认承载建立请求消息， 其中， 该默认 承载建立请求消息携带有 APN及选择的 P-GW的 IP地址。 步骤 304, 驻留有 BBERF的 S-GW在向 PCRFF发送的 "网关控制会话 建立指示" 消息中携带 UE的标识 NAI、 APN。 步骤 305 , PCRF根据用户的签约数据、网络策略、承载属性等制定 PCC 规则和 QoS规则， 同时， 也可能制定相应的事件触发器， PCRF通过 "网关 控制会话建立确认" 消息将 QoS规则和事件触发器发送给 S-GW, S-GW安 装 QoS规则和事件触发器。 步骤 306, S-GW向 P-GW发送 "代理绑定更新" 请求消息， 其中， 该 "代理绑定更新" 请求消息中携带有 NAI、 APN。 需要说明的是， 步骤 306可以在接收到步骤 303的消息后执行， 而不必 等待步骤 305的响应。 步骤 307, 驻留有 PCEF的 P-GW向 PCRF发送 "IP-CAN会话建立指 示，， 消息， 其中， 该 "IP-CAN会话建立指示" 消息中携带有 NAI、 APN, 还携带有 P-GW为 UE分配的 IP地址； PCRF通过 NAI和 APN "IP-CAN 会话建立指示" 消息和步骤 305中的 "网关控制会话建立指示" 消息进行关 联， 从而^ 1夺两消息在 PCRF建立的信息关联到同一个 IP-CAN会话。 步骤 308 , PCRF向 P-GW返回 "IP-CAN会话建立确认" 消息， 其中， 该 "IP-CAN会话建立确认"消息携带有相应的 PCC规则和事件触发器 , PCEF 安装 PCC规则和事件触发器; 需要说明的是，如果步骤 307中 IP-CAN会话建立指示消息中携带的信 息导致 QoS规则发生了变化， PCRF将通过网关控制和 QoS规则提供消息将 新的 QoS规则发送给可信任非 3GPP接入网关，若事件触发器也发生了改变， 则提供新的事件触发器， 该消息可以和步骤 308同时执行。 BBERF接收到消 息后返回确认消息。 步骤 309, P-GW向 S-GW返回 "代理绑定确认" 消息， 其中， 该 "代 理绑定确认" 消息中携带有 P-GW为 UE分配的 IP地址。 步骤 310 , S-GW向 MME返回默认 载建立确认消息， 其中， 该默认 载建立确认消息携带有 UE的 IP地址。 步骤 311 , MME、 eNodeB、 UE之间交互， 建立无线 载。 步骤 312 , 在无线承载建立之后， MME向 S-GW发送更新承载请求， 通知 eNodeB的地址信息等， S-GW返回应答消息。 步骤 313 , UE执行特定的非 3GPP接入过程，接入可信任非 3GPP接入 网。 步骤 314, 在 UE接入到可信任非 3GPP接入网之后， 向 HSS/AAA请 求进行 EPS接入认证； 在 HSS/AAA接收到 EPS接入认证请求之后， 对发出 请求的 UE进行认证；在 HSS/AAA完成对 UE的认证之后 ,向可信任非 3GPP 接入网关发送返回在 3GPP接入中选择的 P-GW和 UE签约的 APN, 这里的 APN包括默认 APN。 步骤 315 , 在认证成功之后， 层 3的附着流程被触发， UE向可信任接 入网关发送的消息携带 Multiple Access指示。 步骤 316 , 驻留有 BBERF的可信任非 3GPP接入网关在向 PCRF发送 "网关控制会话建立指示" 消息， 其中， "网关控制会话建立指示" 消息中携 带有 UE的标识 NAI、 APN、 Multiple Access指示。 步骤 317, PCRF才艮据 Multiple Access指示 , 判断 UE为多接入 , 并且 根据 NAI、 APN将该消息与步骤 304和步骤 307的消息进行关联， 从而将三 条消息在 PCRF 建立的信息关联到同一个 IP-CAN会话。 进一步地， PCRF 根据用户的签约数据、 网络策略、 承载属性等对将要迁移到通过非 3GPP接 入的 IP-CAN会话的业务制定 PCC规则和 QoS规则 , 同时， 也可能制定相 应的事件触发器； PCRF 通过 "网关控制会话建立确认" 消息将这些新制定 的 QoS规则和事件触发器发送给 BBERF, BBERF安装 QoS规则和事件触发 器。 步骤 318 , 可信任非 3GPP接入网关向 P-GW发送 "代理绑定更新" 请 求消息， 其中， 该 "代理绑定更新，，请求消息中携带有 NAI、 APN和 Multiple Access指示， 步骤 318可以在接收到步骤 315的消息后就执行， 不必等待步 骤 317的响应。 步骤 319 ,驻留有 PCEF的 P-GW采用步骤 307中建立的 Diameter会话 , 向 PCRF发送 "IP-CAN会话 4爹改指示" 消息， 其中， 该 "IP-CAN会话 4爹改 才旨示" 消息中携带有 NAI、 APN、 IP地址。 步骤 320, PCRF向 P-GW返回 "IP-CAN会话爹改确认" 消息， 其中， "IP-CAN会话修改确认" 消息中携带步骤 317中制定的 PCC规则和事件触 发器， P-GW更新 PCC规则和事件触发器。 PCRF有可能根据步骤 319携带 的信息 , 再次更新 PCC规则。 需要说明的是，如果步骤 319中 IP-CAN会话修改指示消息中携带的信 息导致步骤 317中制定的 QoS规则发生了变化， PCRF将通过网关控制和 QoS 规则提供消息将新的 QoS规则发送给可信任非 3GPP接入网关， 若事件触发 器也发生了改变， 提供新的事件触发器， 该消息可以和步骤 320同时发送。 可信任非 3GPP接入网关接收到消息后返回网关控制和 QoS规则提供确认消 息。 步骤 321 , P-GW将自己的 IP地址等信息保存到 HSS, 在 HSS中注册 多接入。 步骤 322, P-GW向可信任非 3GPP接入网关返回 "代理绑定确认" 消 息， 其中， 该 "代理绑定确认" 消息中携带有 P-GW为 UE分配的 IP地址。 步骤 323 , 可信任非 3GPP接入网关向 UE返回应答消息， 其中， 该应 答消息携带有 UE的 IP地址。 通过以上流程， PCRF可以针对同时通过 3GPP接入和非 3GPP接入的 IP-CAN会话进行策略计费控制。 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。 下面将参考附图并结合实施例来详细说明本发明。 方法实施例 根据本发明的实施例， 提供了一种基于多接入技术的接入处理方法， 该 方法应用于多接入场景下， 由网络侧发起的资源预留过程中， 该方法包括： PCEF 确定业务数据流传输的接入网连接 , 并将确定的接入网连接通知给 PCRF， 其中， PCEF可以根据配置信息或网络策略进行确定业务数据流传输 的接入网连接。 此后， PCRF 将相应的 QoS 规则发送给接入网连接中的 BBERF, 以使该 BBERF安装 QoS规则， 并才艮据 QoS规则发起资源预留过程 或资源释放过程。 其中， 接入网连接通过以下信息之一来唯一标识： IP-CAN 类型和 /或无线接入接入类型、 用于指示接入网连接的网络协议地址， 上述的 配置信息可以由系统预先设置。 在具体的实现过程中， PCEF可以将绑定指示发送给 PCRF, 其中， 该 绑定指示中携带有接入网连接的信息。 其中， PCEF可以通过以下消息之一将绑定指示发送给 PCRF： IP-CAN 会话建立指示消息、 IP-CAN 会话修改指示消息、 策略计费规则确认消息、 策略计费规则请求消息。 具体地 , 对于该绑定指示的发送可以才艮据以下情况进行处理： ( 1 )在建立 IP-CAN会话时 , PCEF可以通过 IP-CAN会话建立指示消 息将绑定指示发送给 PCRF。
( 2 )在建立 IP-CAN会话之后， PCEF可以通过 IP-CAN会话 4爹改指示 消息、 策略计费规则确认消息或策略计费规则请求消息将绑定指示发送给 PCRF。 下面将结合实例对本发明实施例的实现过程进行详细描述。 实施例一 本实施例描述的是基于如图 3所示的流程附着。图 4是才艮据本发明实施 例一的流程图， 如图 4所示， 描述的是 UE通过 E-UTRAN和可信任非 3GPP 接入网多接入， 建立 IP-CAN会话后， 访问新的业务， 由网络侧发起资源预 留的过程包括如下的步骤 401至步骤 409： 步骤 401 , UE请求访问新的业务， 向提供业务信息的 AF 1发送请求消 息， AF1接收到该请求消息后， 建立新的 AF会话并提供业务信息， 对应的 业务数据流（Service Data Function, 筒称为 SDF ) 为 SDF1。 进一步地， 该 请求消息中还可以携带 UE选择传输 SDF 1的目标接入网连接的指示。 步骤 402 , AF 1向 PCRF发送业务应用消息， 该业务应用消息中携带有 访问业务的 UE的 IP地址， 进一步地， 该业务应用消息还可以携带 UE的标 识及 UE选择传输 SDF1的目标接入网连接的指示。 步骤 403 , PCRF接收业务应用消息， 并保存业务信息。 步骤 404 , PCRF向 AF 1返回确认消息。 步骤 405 , PCRF才艮据 UE的 IP地址和 UE的标识， 识别出图 3中流程 所建立的 IP-CAN会话。 PCRF根据用户的签约信息、 网络策略和业务信息 等业务特性制定 PCC规则 （ Rulesl )。 步骤 406, PCRF向 P-GW中的 PCEF通过策略计费规则提供消息发送 PCC Rulesl , PCEF安装 PCC Rulesl并才艮据配置信息或网络策略决定该业务 的数据流通过 E-UTRAN传送，将 PCC规则与 E-UTRAN接入连接进行关联。 当 PCEF检测到应用 PCC Rulesl的业务数据流时，这些业务数据流要发送给 通过 E-UTRAN接入网的连接。 步骤 407, PCEF返回确认消息， 并在确认消息中携带绑定指示， 绑定 指示表示 PCEF决定的业务数据流与传输业务数据流的接入网连接的绑定关 系。 该绑定指示通过携带唯一区分各接入网连接的信息来标识 PCEF确定的 接入网连接， 例如， 该绑定指示携带 IP-CAN 类型和 /或无线接入技术类型 ( RAT Type ),在这里由于 PCEF决定业务数据流通过 E-UTRAN接入网连接 传输， 所以 IP-CAN类型取值为 3GPP-EPS , RAT Type取值为 E-URTAN。 还 可以携带 S-GW/BBERF的 IP地址来标识接入网连接。 当然其他唯一区分各 接入网连接的信息同样适用。 步骤 408 , PCRF 根据绑定指示， 获知 PCEF 决定该业务数据流通过 E-UTRAN传输， 所示根据 E-UTRAN的接入特性、 用户签约信息、 网络策 略制定 PCC Rulesl对应的的 QoS Rules 1。 PCRF向 S-GW中的 BBERF通过 网关控制和 QoS规则提供消息发送 QoS Rules 1。 如果 PCRF需要修改步骤 405中制定的 PCC Rules 1 , 贝 ^ PCRF将通过策略计费规则提供消息向 PCEF 更新之前下发的 PCC规则。 步骤 409, BBERF安装 QoS Rules 1 , E-UTRAN执行相应的策略， 并发 起资源预留过程。 BBERF向 PCRF返回确认消息。 需要说明的是， 在其它实施例中， 如果 PCEF决定该业务将通过可信任 非 3GPP接入网连接传输， 贝' j PCEF在向 PCRF返回的确认消息中携带绑定 指示， 表明当 PCEF检测到应用 PCC Rulesl的业务数据流时， 这些业务数据 流要发送给通过可信任非 3GPP接入网接入连接。 绑定指示的实现可以通过 携带该可信任非 3GPP接入网的 IP-CAN Type和 /或 RAT Type, 如果可信任 非 3GPP接入网为 WiMAX, 贝' J IP-CAN Type 为 WiMAX。 绑定才旨示的实现 还可以通过携带可信任非 3GPP接入网关 /BBERF的 IP地址。 当然其他唯一 区分各接入网连接的信息同样适用。 PCRF根据绑定指示， 制定对应的 QoS Rules 1 ,并向可信任非 3GPP接入网关中的 BBERF发送 QoS Rules 1。 BBERF 安装 QoS Rules 1 , 在可信任非 3GPP接入网中发起资源预留过程。 在其他实施例中， 如果 UE同时通过 E-UTRAN和不可信任非 3GPP接 入的多接入， 则此时的处理方法和流程与上述描述的过程类似， 不同之处在 于当 PCEF决定业务数据流通过不可信任非 3GPP接入网连接， 该绑定指示 还可以携带 ePDG/BBERF的 IP地址， PCRF向 ePDG中的 BBERF发送 QoS Rules 1。 实施例二 该实施例包括以下两个部分：
( 1 )与图 3的流程类似， UE建立多接入的 IP-CAN会话， 不同之处在 于： 在步骤 319的 "IP-CAN会话修改指示，， 消息中除了携带有 NAI、 APN、 IP地址之外， 还携带有绑定指示。 当 PCEF根据配置信息或网络策略决定该 UE的所有需要由网络发起资源预留的业务， 其业务数据流都通过 E-URTAN 接入网连接传输。该绑定指示通过携带 IP-CAN类型和 /或无线接入类型 RAT Type, 取值分别是 3GPP-EPS和 E-UTRAN来表示。 该绑定指示还可以通过 携带 S-GW/BBERF的 IP地址， PCRF保存该绑定指示。 当然其他唯一区分 各接入网连接的信息同样适用。 此外， 绑定指示还可以通过步骤 307 的 "IP-CAN会话建立指示" 消息发送给 PCRF, PCRF进行保存。
( 2 ) UE发起业务请求 , 由网络发起资源预留。 图 5是才艮据本发明实施 例二的流程图， 如图 5所示， 包括如下的步骤 501至步骤 509: 步骤 501 , UE请求访问新的业务， 向提供业务信息的 AF 1发送请求消 息， AF1接收到该请求消息后， 建立新的 AF会话并提供业务信息， 对应的 业务数据流为 SDF1。进一步地，该请求消息中还可以携带 UE选择传输 SDF1 的目标接入网连接的指示。 步骤 502 , AF 1向 PCRF发送业务应用消息， 其中， 该业务应用消息携 带有访问业务的 UE的 IP地址 , 进一步地 , 该业务应用消息还可以携带 UE 的标识及 UE选择传输 SDF 1的目标接入网连接的指示。 步骤 503 , PCRF接收该业务应用消息， 并保存业务信息。 步骤 504, PCRF向 AF1返回确认消息。 步骤 505 , PCRF才艮据 UE的 IP地址和 UE的标识 ,识别出建立的 IP-CAN 会话。 jt匕时， PCRF确定 UE通过可信任非 3GPP接入网 （例如， WLAN )和 E-UTRAN多接入。并且，才艮据从 PCEF中获取的绑定指示 ,确定在 E-UTRAN 的接入网连接中进行资源预留。 PCRF 根据接入网特性、 用户的签约信息、 网络策略和业务信息等业务特性制定 PCC Rules 1、 QoS Rulesl。 步骤 506 ,由于在 E-UTRAN的接入网连接中进行资源预留，因此， PCRF 向 S-GW中的 BBERF通过网关控制和 QoS规则提供消息发送 QoS Rules 1。 步骤 507, BBERF安装 QoS Rules 1 , E-UTRAN执行相应的策略， 进行 资源预留。 BBERF向 PCRF返回确认消息。 步骤 508 , PCRF向 P-GW中的 PCEF通过策略计费规则提供消息发送 PCC Rules 1 , 其中， 该策略计费规则提供消息中可以进一步携带绑定指示， 向 PCEF进行确认。 步骤 509 , PCEF安装 PCC Rules 1 , 将 PCC规则与 E-UTRAN接入连接 进行关联，并向 PCRF返回确认消息。当 PCEF检测到该业务数据流时， PCEF 将向 E-UTRAN接入网连接发送业务数据流。 如果步骤 508 中， PCEF接收到绑定指示后对绑定进行修改， PCEF将 在步骤 509中返回新的绑定指示给 PCRF。 PCRF再进行相应的 4爹改。 需要说明的是， 在其它实施例中 , 如果 PCEF决定该业务将通过可信任 非 3GPP接入传输， 则在图 3的步骤 307或步骤 319的消息中， 绑定指示实 现时可以携带该可信任非 3GPP接入网连接的 IP-CAN Type和 /或 RAT Type, 如果可信任非 3GPP接入网为 WiMAX, 贝' J IP-CAN Type 为 WiMAX, 绑定 指示实现时还可以携带可信任非 3GPP接入网关 /BBERF的 IP地址。 PCRF 根据绑定指示， 获知网络发起的资源预留要在通过可信任非 3GPP接入网的 连接中进行， 即， 业务数据流通过可信任非 3GPP接入的连接传输。 在其他实施例中， 如果 UE同时通过 E-UTRAN和不可信任非 3GPP接 入的多接入， 则此时的处理方法和流程与上述描述的过程类似， 不同之处在 于： 当 PCEF决定业务数据流通过不可信任非 3GPP接入网连接， 该绑定指 示还可以携带 ePDG/BBERF的 IP地址， PCRF向 ePDG中的 BBERF发送 QoS Rules 1。 可以看出， 上述实施例一和实施例二的不同之处在于： 在实施例一中，
PCEF针对 UE请求的每一个业务的进行决策， 决定业务数据流传输的接入 网， 然后通知 PCRF; 在实施例二中， PCEF决定 UE的所有需要由网络发起 资源预留业务的数据流都通过一个接入网传输通知 PCRF。 实施例三 本实施例描述的是由于 P-GW决定断开 UE通过 E-UTRAN接入的连接 或者决定改变绑定关系时，将 SDF业务数据流迁移到 UE通过可信任非 3GPP 接入建立的连接上， 从而导致改变数据流传送路径的流程图。 图 6是根据本 发明实施例三的流程图， 如图 6所示， 具体包括如下的步骤 601至步骤 607: 步骤 601 , P-GW中 PCEF接收到内部触发或外部触发， 请求将 SDF1 迁移到可信任非 3GPP接入。 当 PCEF检测到应用 PCC Rules Γ的业务数据流 时， 这些业务数据流要发送给通过可信任非 3GPP接入网接入的连接。 步骤 602, PCEF向 PCRF发送策略计费规则请求消息， 该策略计费规 则请求消息中携带有将 SDF1迁移到可信任非 3GPP接入网的绑定指示，， 该 绑定指示，表明， 绑定指示，实现可以通过携带该可信任非 3GPP 接入网的 IP-CAN Type和 /或 RAT Type, 如果可信任非 3GPP接入网为 WiMAX, 则 IP-CAN Type 为 WiMAX。 绑定指示，实现还可以是可信任非 3GPP接入网关 /BBERF的 IP地址。 当然其他唯一区分各接入网连接的信息同样适用。 进一 步地， 该消息中还可以携带迁移的原因。 步骤 603 , PCRF接收到策略计费规则请求消息后， 根据绑定指示， 获 知 PCEF决定该 SDF1通过可信任非 3GPP接入网传输， 根据可信任非 3GPP 接入网的接入特性重新制定 PCC Rules 1，和对应的 QoS Rules 1， , 并通过策略 计费规则确认消息将 PCC Rulesl '发送给 PCEF , 然后， PCEF 安装 PCC Rules 1 '„ 步骤 604, PCRF向 S-GW中的 BBERF发送网关控制和 QoS规则提供 确认消息， 该确认消息中携带有指示 BBERF删除 QoS Rulesl的信息。 步骤 605 , BBERF向 PCRF返回确认消息。 步骤 606, PCRF通过网关控制和 QoS规则提供消息将 QoS Rulesl '发 送给可信任非 3GPP接入网关中的 BBERF。 步骤 607, BBERF安装 QoS Rulesl ' , 并向 PCRF返回确认消息。 需要说明的是， 对于 UE同时通过 E-UTRAN和不可信任非 3GPP接入 网多接入建立 IP-CAN会话的场景， PCRF将业务的 IP数据流与接入绑定的 方法与上述实施例类似， 在 不再赘述。 需要说明的是， 对于 UE同时通过 E-UTRAN (其中， S-GW和 P-GW 之间采用 GTP协议）和非 3GPP接入网多接入建立 IP-CAN会话的场景， 处 理方法与上述实施例类似， 在此不再赘述。 不同点在于 PCRF不需要将相应 的 QoS Rules发送给 S-GW中的 BBERF。 对于 UE同时通过 E-UTRAN和非 3GPP接入网多接入的场景，并且 UE 通过非 3GPP接入网接入时采用 DSMIPv6协议。 PCRF将业务的 IP数据流 与接入绑定的方法与上述实施例类似， 在 不再赘述。 装置实施例 居本发明的实施例， 提供了一种 PCEF , 应用于多接入场景下， 由网 络侧发起的资源预留过程中， 可以用于实现上述方法。 图 7是根据本发明实 施例的 PCEF的结构框图， 如图 7所示， 该 PCEF包括： 确定模块 72和通知 模块 74 , 下面对上述结构进行描述。 确定模块 72 , 用于根据配置信息或网络策略确定业务数据流传输的接 入网连接， 其中， 上述的配置信息可以由系统预先设置； 通知模块 74 , 连接 至确定模块 72 , 用于将确定模块 72确定的接入网连接通知给 PCRF , 其中， 接入网连接可以通过以下信息之一表示： IP-CAN类型和 /或无线接入类型、 用于指示接入网连接的网络协议地址。 通过该实施例， 提供了可以确定业务数据流传输的接入网的 PCEF, 该 PCEF将确定的接入网连接通知给 PCRF , 以便 PCRF将相应的 QoS规则发 送给接入网连接中的 BBERF , 该 BBERF安装 QoS规则 , 并才艮据 QoS规则 发起资源预留过程或资源释放过程。 系统实施例 根据本发明的实施例， 提供了一种基于多接入技术的策略计费控制系 统。 图 8是才艮据本发明实施例的基于多接入技术的策略计费控制系统的结构 才匡图， 如图 8所示， 该系统包括 PCEF 2和 PCRF 4 , 下面对其中的结构进行 详细描述。
PCEF 2包括： 确定模块 22 , 用于才艮据配置信息确定业务数据流传输的 接入网连接； 通知模块 24 , 连接至确定模块 22 , 用于夺确定模块 22确定的 接入网连接通知给 PCRF。 该 PCEF 2可以用图 7的 PCEF来实现。
PCRF 4连接至 PCEF 2 , 其包括： 接收模块 42 , 用于接收来自 PCEF 的接入网连接的信息； 发送模块 44 , 连接至接收模块 42 , 用于根据模块 42 接收的接入网连接的信息， 将相应的服务质量规则发送给接入网连接中的 BBERF , 以使 BBERF才艮据 QoS规则发起资源预留或资源释放过程。 综上所述， 通过本发明的上述实施例， 采用 PCEF决定业务数据流传输 的接入网连接并通知 PCRF的方法， 解决了目前当 UE同时通过多个接入网 接入时，网络无法根据业务在合适的接入网连接中发起资源预留过程的问题， 进而实现了当 UE同时通过多个接入网接入时， 网络可以才艮据业务在合适的 接入网连接中发起资源预留过程。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布 在多个计算装置所组成的网络上， 可选地， 它们可以用计算装置可执行的程 序代码来实现， 从而， 可以将它们存储在存储装置中由计算装置来执行， 或 者将它们分别制作成各个集成电路模块， 或者将它们中的多个模块或步骤制 作成单个集成电路模块来实现。 这样， 本发明不限制于任何特定的硬件和软 件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的^^申和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
