Description

策略控制方法及装置技术领域本发明涉及通信领域，具体而言，涉及一种策略控制方法及装置。背景技术第三代合作伙伴计划（3rd Generation Partnership Project, 简称为 3GPP)的策略和计费控制（Policy and Charging Control, 简称为 PCC) 架构是一个能够应用于多种接入技术的功能框架。例如，应用于通用移动通信*** （ Universal Mobile Telecommunications System,简称为 UMTS)的陆上无线接入网（UMTS Terrestrial Radio Access Network, 简称为 UTRAN)、全球移动通信*** （Global system for Mobile Communication, 简称为 GSM) /GSM数据增强演进（Enhanced Data rates for Global Evolution, 简称为 EDGE)无线接入网、互通无线局域网（I-WLAN) 以及演进的分组 *** （Evolved Packet System, 简称为 EPS) 等。图 1是根据相关技术的 Rel-8 PCC非漫游架构的示意图，如图 1所示，对该 PCC 架构中的各个逻辑功能实体及其接口功能进行描述。应用功能实体（Application Function, 简称为 AF)，提供业务应用的接入点，这些业务应用所使用的网络资源需要进行动态的策略控制。在业务面进行参数协商时， AF 将相关业务信息传递给策略与计费规则功能实体（Policy and Charging Rules Function, 简称为 PCRF)，如果这些业务信息与 PCRF的策略相一致，则 PCRF接受该协商；否贝 U， PCRF拒绝该协商，并在反馈中同时给出 PCRF可接受的业务参数。随后， AF可将这些参数返回给用户设备（User Equipment, 简称为 UE)。其中， AF和 PCRF之间的接口是 Rx接口。 TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a policy control method and apparatus. BACKGROUND The Policy and Charging Control (PCC) architecture of the 3rd Generation Partnership Project (3GPP) is a functional framework that can be applied to multiple access technologies. For example, a Universal Mobile Telecommunications System (UMTS) UMTS Terrestrial Radio Access Network (UTRAN), and a Global System for Mobile Communication (Global System for Mobile Communication) GSM)/Enhanced Data Rates for Global Evolution (EDGE) radio access network, interworking wireless local area network (I-WLAN), and Evolved Packet System (EPS). FIG. 1 is a schematic diagram of a Rel-8 PCC non-roaming architecture according to the related art. As shown in FIG. 1, each logical functional entity and its interface functions in the PCC architecture are described. Application Function Entity (AF) provides access points for service applications. The network resources used by these service applications require dynamic policy control. When the parameter negotiation is performed on the service plane, the AF sends the related service information to the Policy and Charging Rules Function (PCRF). If the service information is consistent with the PCRF policy, the PCRF accepts the negotiation. No, the PCRF rejects the negotiation and gives the business parameters acceptable to the PCRF in the feedback. The AF can then return these parameters to the User Equipment (UE). The interface between AF and PCRF is the Rx interface.

PCRF是 PCC的核心，负责策略决策和计费规则的制定。 PCRF提供了基于业务数据流的网络控制规则，这些网络控制包括业务数据流的监测、门控（Gating Control )、服务质量（Quality of Service, 简称为 QoS)控制以及基于数据流的计费规则等。 PCRF 将其制定的策略和计费规则发送给策略与计费执行功能实体（Policy and Charging Enforcement Function, 简称为 PCEF)执行，同时， PCRF还需要保证这些规则和用户的签约信息一致。 PCRF制定策略和计费规则的依据包括：从 AF获取与业务相关的信息；从用户签约数据库（Subscription Profile Repository, 简称为 SPR) 获取用户策略计费控制签约信息；从 PCEF获取与承载相关网络的信息。 PCEF, 用于在承载面执行 PCRF所制定的策略和计费规则。 PCEF按照 PCRF所发送的规则中的业务数据流过滤器对业务数据流进行监测，进而对这些业务数据流执行 PCRF所制定的策略和计费规则。在承载建立时， PCEF按照 PCRF发送的规则进行 QoS授权，并根据 AF的执行进行门控控制。根据 PCRF发送的计费规则， PCEF执行相应的业务数据流计费操作，计费既可以是在线计费，也可以是离线计费。如果是在线计费，则 PCEF需要和在线计费*** （Online Charging System, 简称为 OCS) —起进行信用管理。离线计费时， PCEF和离线计费*** （Offline Charging System, 简称为 OFCS) 之间交换相关计费信息。 PCEF与 PCRF之间的接口是 Gx接口，与 OCS 之间的接口是 Gy接口，与 OFCS之间的接口是 Gz接口。 PCEF通常位于网络的网关 (Gate-Way,简称为 GW)内，如 GPRS中的 GPRS网关支持节点（GGSN)以及 I-WLAN 中的分组数据网关（Packet Data Gateway, 简称为 PDG)。承载绑定和事件报告功能实体（Bearer Binding and Event Reporting Function, 简称为 BBERF), 其功能包括承载绑定、上行承载绑定的验证、以及事件报告。当 UE通过 E-UTRAN接入，并且 S-GW与 P-GW之间采用 PMIPv6协议时， BBERF就位于 S-GW, 当 UE通过可信任非 3GPP接入***接入时， BBERF位于可信任非 3GPP接入网关，当 UE通过不可信任非 3GPP接入***接入时、 BBERF位于演进的分组数据网关（Evolved Packet Data Gateway, 简称为 ePDG)。此时， PCEF不再执行承载绑定功能。用户签约数据库（SPR) 存储了和策略控制与计费相关的用户策略计费控制签约信息。 SPR和 PCRF之间的接口是 Sp接口。在线计费***（OCS)，与 PCEF—起进行在线计费方式下用户信用的控制和管理。离线计费*** （OFCS), 与 PCEF—起完成离线计费方式下的计费操作。以上 PCC架构通过各功能实体实现了对 UE为访问一个分组数据网络 ( Packet Data Network, 简称为 PDN) 所建立的 IP连接接入网（IP Connectivity Access Network, 简称为 IP-CAN) 会话的策略计费控制。目前， PCC架构支持称为被赞助数据连接（Sponsored data connectivity )。图 2是根据相关技术的部署赞助数据连接业务的架构的示意图，如图 2所示，所谓被赞助数据连接是指用户所访问业务产生的用量消耗，并不是由用户自己承担，而是由赞助商（Sponsor)承担，访问内容为应用业务提供商（Application Service Provider, 简称为 ASP)提供。此时，当用户发起该类业务访问时， AF在向 PCRF提供业务信息时，还会向 PCRF提供业务提供方赞助访问该类业务的用量阈值（即用户可以免费访问该类业务的用量），在本发明中，被赞助数据连接等同于被赞助数据连接业务。此时， PCRF根据 AF下发的用量阈值设置 PCEF监测的用量阈值，当到达阈值时， PCEF通知 PCRF。为了实现对被赞助数据连接业务的策略计费控制，在 SPR中将会保存赞助数据连接文档，其中包括赞助商标识（Sponsor Identity)和每个应用业务提供商（Application Service Provider) 的应用列表。 AF向 PCRF提供的业务信息时也会携带赞助商标识、应用业务提供商标识以及应用标识等信息， PCRF将根据从 SPR中获取的签约文档对 AF提供的业务信息进行授权，是否允许进行被赞助数据连接，以及对应的 QoS等。但是，如果被赞助数据连接业务的流量过大或用户数过多，则会导致网络负荷过大，而影响其它用户或业务（例如非签约赞助数据连接业务的用户，或者签约该类业务的用户的运营商自有业务）的使用，进而影响网络性能。发明内容本发明提供了一种策略控制方法及装置，以至少解决相关技术中被赞助数据连接业务的流量过大或用户数过多会导致网络负荷过大的问题。为了实现上述目的，根据本发明的一个方面，提供了一种策略控制方法。根据本发明的策略控制方法包括： PCRF获取被赞助数据的 QoS信息，其中 QoS 信息为被赞助数据的赞助商预先签约的信息； PCRF根据被赞助数据的 QoS信息，制定或更新 PCC/QoS策略。 PCRF获取被赞助数据的 QoS信息包括: PCRF从 SPR或者 UDC接收被赞助数据的 QoS信息。 The PCRF is the core of the PCC and is responsible for policy decision making and billing rules. The PCRF provides network control rules based on service data flows, including traffic data flow monitoring, Gating Control, Quality of Service (QoS) control, and data flow based charging rules. . The PCRF sends the policies and charging rules to the Policy and Charging Enforcement Function (PCEF). The PCRF also needs to ensure that these rules are consistent with the user's subscription information. The basis for formulating the policy and charging rules by the PCRF includes: obtaining information related to the service from the AF; obtaining the subscription information of the user policy charging control from the Subscription Profile Repository (SPR); and obtaining the network related to the bearer from the PCEF information. PCEF, used to perform the policy and charging rules established by the PCRF on the bearer plane. The PCEF monitors the service data flow according to the service data flow filter in the rule sent by the PCRF, and then executes the policy and charging rules formulated by the PCRF for these service data flows. When the bearer is established, the PCEF performs QoS authorization according to the rules sent by the PCRF, and performs gate control according to the execution of the AF. According to the charging rule sent by the PCRF, the PCEF performs a corresponding service data flow charging operation, and the charging can be either online charging or offline charging. In the case of online charging, the PCEF needs to perform credit management with the Online Charging System (OCS). When offline charging, the PCEF exchanges relevant charging information with the Offline Charging System (OFCS). The interface between the PCEF and the PCRF is a Gx interface, the interface with the OCS is a Gy interface, and the interface between the OFCS and the OFCS is a Gz interface. The PCEF is usually located in a Gateway (Gate-Way, GW for short), such as a GPRS Gateway Support Node (GGSN) in GPRS and a Packet Data Gateway (PDG) in I-WLAN. Bearer Binding and Event Reporting Function (BBERF), whose functions include bearer binding, verification of uplink bearer binding, and event reporting. When the UE accesses through the E-UTRAN, and the PM-IPv6 protocol is adopted between the S-GW and the P-GW, the BBERF is located at the S-GW, and when the UE accesses through the trusted non-3GPP access system, the BBERF is located in the trusted non- The 3GPP access gateway, when the UE accesses through the untrusted non-3GPP access system, the BBERF is located in the Evolved Packet Data Gateway (ePDG). At this time, the PCEF no longer performs the bearer binding function. The User Contracted Database (SPR) stores user policy charging control subscription information related to policy control and charging. The interface between SPR and PCRF is the Sp interface. The Online Billing System (OCS), in conjunction with PCEF, controls and manages user credits in an online charging mode. The offline charging system (OFCS), together with the PCEF, completes the charging operation in the offline charging mode. The above PCC architecture implements a policy plan for an IP Connectivity Access Network (IP-CAN) session established by the UE to access a Packet Data Network (PDN) through various functional entities. Fee control. Currently, PCC architecture support is called Sponsored Data Connectivity. 2 is a schematic diagram of an architecture for deploying a sponsored data connection service according to the related art. As shown in FIG. 2, a so-called sponsored data connection refers to consumption consumption generated by a user's accessed service, which is not borne by the user but is sponsored. Sponsor (Sponsor) assumes that the content of the access is provided by the Application Service Provider (ASP). At this time, when the user initiates this type of service access, the AF provides service information to the PCRF. At the same time, the PCRF is also provided with a usage threshold for the service provider to sponsor access to such services (i.e., the user can access the usage of such services for free). In the present invention, the sponsored data connection is equivalent to the sponsored data connection service. At this time, the PCRF sets the usage threshold of the PCEF monitoring according to the usage threshold issued by the AF. When the threshold is reached, the PCEF notifies the PCRF. In order to implement policy charging control for the sponsored data connection service, the sponsored data connection document will be saved in the SPR, including the sponsor identity and the application list of each application service provider. The service information provided by the AF to the PCRF also carries information such as the sponsor identification, the application service provider identifier, and the application identifier. The PCRF will authorize the service information provided by the AF according to the contract document obtained from the SPR, and whether or not to be sponsored. Data connection, and corresponding QoS, etc. However, if the traffic of the sponsored data connection service is too large or the number of users is too large, the network load will be too large, which will affect other users or services (such as users who are not contracted to sponsor data connection services, or users who sign up for such services). The use of the carrier's own business), which in turn affects network performance.

The maximum number of users pre-signed by the sponsor, and the QoS information indication indicating that the QoS resources allowed by the sponsor are insufficient. Preferably, the QoS information of the sponsored data may be sent to the PCRF by the SPR, or may be acquired by the PCRF. The implementation process of the embodiment of the present invention will be described in detail below with reference to examples. Preferred Embodiment 1 FIG. 4 is an interaction flowchart according to a preferred embodiment of the present invention. As shown in FIG. 4, the following steps S401 to S411 are included. Step S401: In the process of the UE requesting to establish an IP-CAN session, the gateway where the PCEF is located receives the IP-CAN session establishment request message, and carries the user identifier and the PDN network requested to be accessed in the IP-CAN session establishment request message. PDN logo. Step S402: The PCEF sends an IP-CAN session establishment indication message to the PCRF, and carries the user identifier, the PDN identifier, and an IP address (IP Address) allocated for the UE in the IP-CAN session establishment indication message. At this time, if the PCRF has not interacted with the SPR and obtains the sponsored data connection document, then the PCRF needs to interact with the SPR; or, the PCRF interacts with the SPR after the device is started to obtain the sponsored data connection document. Step S403: The PCRF determines that there is no subscription data of the user according to the user identifier, and the PCRF sends a subscription document request to the SPR, and carries the user identifier and the PDN identifier in the subscription document request. Step S404, the SPR returns the user subscription information (ie, the contracted document response) according to the user identifier and the PDN identifier. At this time, if the SPR has not provided the PCRF with the sponsored data connection document and the sponsor's allowed QoS information (such as sponsor MBR, GBR, maximum number of users, etc.), then the SPR will be provided to the PCRF; or, the PCRF is After the device is booted, it interacts with the SPR to obtain the sponsored data connection document and the sponsor's allowed QoS information. Step S405: The PCRF formulates a policy according to the returned user subscription information, the network policy, and the access information of the UE. The policy includes a PCC rule, an event trigger, and the like, and the PCRF returns the formulated policy to the PCEF. In step S406, the PCEF installs and executes the policy. Such as PCC rules, event triggers, etc. The gateway where the PCEF is located establishes an IP-CAN session to the return response, carrying the assigned IP address. Step S407, the UE connects to the server of the application service provider (ASP) of the third party through the IP-CAN session established in step S401-step S406, and requests the service, and the ASP server decides to provide the sponsored data for the user. connection. The ASP server provides dynamic sponsored data connection information to the AF, including the sponsor identifier, the ASP identifier, the application identifier, and the sponsored user information (such as IP Address), the IP flow information of the sponsored service, and the allowable usage threshold. Usage Threshold (AUT), where the AF is located in the visited network or has a contractual relationship with the visited network. Step S408: The AF provides the sponsored data connection information to the PCRF, where the information includes a sponsor identifier, an ASP identifier, an application identifier, and the sponsored user information (such as IP Address), and the IP stream information of the sponsored service. If the user plane data does not pass the AF, the AF also provides an Allowed Usage Threshold (AUT). Step S409, the PCRF authorizes the sponsored data connection provided by the AF according to the sponsored data connection subscription document and the sponsor's permitted QoS information locally pre-configured or obtained from the SPR (if the sponsor's allowed QoS information resource is insufficient at present) The authorization request is rejected. If the authorization request is rejected, the PCRF returns a rejection message to the AF, and the process ends; if the sponsor's allowed QoS information satisfies the requested QoS, the authorization is allowed, and the PCRF returns a response message to the AF and continues the subsequent process. ). PCC rules are formulated based on business information, user subscriptions, and network policies. If the AF provides an AUT, the PCRF will provide a usage monitoring strategy to monitor the amount of user-sponsored data connections. Step S410, the PCRF provides a PCC rule to the PCEF. It is also possible to provide a usage monitoring strategy. Step S411, after the PCEF installs and executes the policy, it returns an acknowledgement message to the PCRF. Preferred Embodiment 2 This preferred embodiment describes the change in the subscription information when the SPR senses the business process, such as: sponsorship If the QoS information of the quotient (for example, the sponsor MBR, GBR, and the maximum number of users) changes, the corresponding update needs to be notified to the PCRF, and the PCRF checks and judges, and updates the PCC/QoS policy as needed. FIG. 5 is an interaction flowchart according to a preferred embodiment of the present invention. As shown in FIG. 5, the following steps S501 to S506 are included. In step S501, the SPR detects the subscription information change of an ongoing service (for example, the contracted sponsor allows the QoS information to change, and the sponsored data connection service associated with the sponsor is currently in progress). Step S502: The SPR sends a subscription information update request to the PCRF, and sends the QoS information of the sponsor of the corresponding service (for example, the sponsor MBR, GBR, and the maximum number of users) to the PCRF. Step S503, the PCRF sends an update response message to the SPR. Step S504, the PCRF stores the received updated information, and determines whether a corresponding policy update is required according to the sponsored QoS information of the updated service (for example, the MBR/GBR change of the contract sponsor and affects the existing authorization) Allow MBR/GBR), update the existing policy when needed, and initiate the IP-CAN session modification process to issue the updated policy to the PCEF. In step S505, if it is determined in step S504 that the policy needs to be updated, the PCRF sends the updated policy to the PCEF. Step S506, the related function entity performs a subsequent IP-CAN session modification process according to the prior art. The update of the subscription information may be multi-user or single user granularity, or multiple or one IP-CAN session granularity of the same APN of the user. If the user data is predefined on the PCRF, the policy update and IP-CAN session modification procedure is initiated by the PCRF after the PCRF detects that the sponsor's allowed QoS information is changed. The invention is applicable to the QoS scenario of GBR. It should be noted that the steps shown in the flowchart of the accompanying drawings may be performed in a computer system such as a set of computer executable instructions, and, although the logical order is shown in the flowchart, in some cases, The steps shown or described may be performed in an order different than that herein.
