Description

一种消费限制业务的签约和执行方法及*** Method and system for signing and executing consumption restriction business

技术领域 Technical field

本发明涉及通讯技术领域，尤其涉及一种消费限制业务的签约和执行方法及***。 The present invention relates to the field of communication technologies, and in particular, to a contracting and executing method and system for a consumption restriction service.

背景技术 Background technique

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。 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), a Global System for Mobile Communication (Global System for Mobile Communication, referred to as GSM) / GSM Data Enhanced for Evolution ( EDGE ) radio access network, interworking wireless local area network (I-WLAN), and Evolved Packet System (EPS).

图 1 ( a )为相关技术的 Rel-8 PCC非漫游架构（架构 1 ) 的示意图，以下参照图 1( a )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；否则， 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。 FIG. 1( a ) is a schematic diagram of a related art Rel-8 PCC non-roaming architecture (Architecture 1 ). The following describes the logical function entities and their interface functions in the PCC architecture with reference to FIG. 1( a ): Application functional entity (Application Function, abbreviated as AF), provides access points for service applications. The network resources used by these service applications need 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. Otherwise, the PCRF rejects the negotiation and also 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。 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 monitoring of service data flows, Gating Control, Quality of Service (QoS) control, and Data flow based charging rules, etc. The PCRF sends its policy 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 user policy charging control subscription information from the subscription profile repository (SPR); obtaining the bearer-related network from the PCEF information.

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 ) 。 PCEF, used to enforce 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 performs 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 be credit managed with the Online Charging System (OCS). When offline accounting, the PCEF exchanges relevant charging information with the Offline Charging System (OFCS). The interface between PCEF and PCRF is Gx interface, the interface between OCE and OCS is Gy interface, and the interface between OFCS and OFCS is Gz interface. The PCEF is usually located in the gateway (Gate-Way, GW for short), such as the GPRS Gateway Support Node (GGSN) in GPRS and the Packet Data Gateway (PDG) in I-WLAN.

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之间釆用 ΡΜΙΡνό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。 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 ΡΜΙΡνό protocol is used 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 The non-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.

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。 The User Contracting 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.

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。如图 1 ( b )所示，为图 1 ( a ) 架构下部署 Sy接口的架构图（架构 2 ) 。 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. As shown in Figure 1 (b), the architecture diagram (architecture 2) of the Sy interface is deployed under the architecture of Figure 1 (a).

OCS和 PCRF之间的接口是 Sy接口，该接口上的计费策略会话用于传送计费相关信息。 PCRF从 OCS获取计费相关信息，作为制定 PCC/QoS规则的依据信息之一。 OCS检测到授权配额（例如用量阔值）到达后，可向 PCRF发起计费策略报告，触发 PCRF发起会话修改流程，更新相关规则。 The interface between the OCS and the PCRF is the Sy interface, and the charging policy session on the interface is used to transmit the charging related information. The PCRF obtains charging related information from the OCS as one of the basis information for formulating PCC/QoS rules. After the OCS detects that the authorization quota (for example, the usage threshold) has arrived, it can initiate a charging policy report to the PCRF, trigger the PCRF to initiate a session modification process, and update the related rules.

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。 The above PCC architecture implements a policy plan for the IP Connectivity Access Network (IP-CAN) session established by the UE to access a Packet Data Network (PDN) through various functional entities. Fee control.

目前， PCC架构支持消费限制业务（spending limits )的 QoS控制。所谓消费限制业务的 QoS控制是指用户签约了某个业务（例如视频点播），用户可以在特定时间内（例如每天）累计消费一定限额（例如 10元），该段消费内享受较高的 QoS保障，当累计消费金额超过该限额，只能获得较低的 QoS 保障。这类业务的特点是运营商需要根据消费的情况改变相应的 QoS策略，而消费信息是在 OCS中保存。当用户开展这类业务，策略决策实体（PCRF ) 制定策略时，需要感知用户的消费情况从而制定策略；或是扩展现有计费机制，对这类业务的计费釆用特殊的处理。 Currently, the PCC architecture supports QoS control for spending limits. The QoS control of the so-called consumption restriction service means that the user subscribes to a certain service (such as video on demand), and the user can accumulate a certain limit (for example, 10 yuan) within a certain time (for example, every day), and enjoy high QoS in the consumption. Guarantee, when the accumulated consumption amount exceeds the limit, only low QoS guarantee can be obtained. The characteristic of this type of service is that the operator needs to change the corresponding QoS policy according to the consumption situation, and the consumption information is saved in the OCS. When a user conducts such a service, the Policy Decision Entity (PCRF) needs to perceive the user's consumption to formulate a policy when developing a policy; or extend the existing accounting mechanism to charge a special treatment for the charging of such services.

业务的信用管理功能由 PCEF和 OCS协商完成， OCS根据 PCEF发送的 CCR消息中的计费策略（如费率组 RG )等信息，以及结合本地的计费机制和运营商策略对 PCEF所申请的业务实行信用管控，给 PCEF返回 CCA消息，在消息中携带授权的业务信用配额给 PCEF。现有的在线计费机制，当 PCEF 为该业务向 OCS请求信用额度时，如果该 RG对应的业务受限， OCS会返回 "out of credit" , PCEF将继续向 PCRF上报 "out of credit" , 此时 PCRF会认为请求信用额度失败，业务被中止。 The credit management function of the service is negotiated by the PCEF and the OCS. The OCS applies the information such as the charging policy (such as the rate group RG) in the CCR message sent by the PCEF, and the PCEF application in combination with the local charging mechanism and the operator policy. The business implements credit control, returns a CCA message to the PCEF, and carries the authorized service credit quota to the PCEF. The existing online charging mechanism, when the PCEF requests the credit line for the service to the OCS, if the service corresponding to the RG is limited, the OCS will return "out of credit", and the PCEF will continue to report "out of credit" to the PCRF. At this point, the PCRF will consider that the requested credit limit failed and the service is aborted.

针对消费限制业务，一个改进方案是通过扩展信用管理功能和改进流程来实现。即当 OCS感知到业务受限时，不是返回 "out of credit" , 而是通过携带指示（例如：新的参数标识）给 PCEF, PCEF根据该指示发起 IP-CAN 会话修改流程请求 PCRF为该业务重新授权。 PCRF将为该受限业务重新制定或修改 PCC规则，并下发给 PCEF。 PCEF执行新的规则，并向 OCS申请信用配额。 OCS根据新的计费策略为消费限制业务下发相应的信用配额，来实现信用管控。发明内容 For the consumer-restricted business, an improvement is achieved by extending credit management functions and improving processes. That is, when the OCS perceives the service restriction, instead of returning "out of credit", the OCE sends an indication (for example, a new parameter identifier) to the PCEF, and the PCEF initiates an IP-CAN session modification procedure according to the indication to request the PCRF as the service. Reauthorize. The PCRF will redefine or modify the PCC rules for the restricted service and deliver it to the PCEF. PCEF enforces new rules and requests a letter from OCS Use quotas. Based on the new charging policy, OCS issues corresponding credit quotas for consumption-restricted services to implement credit management and control. Summary of the invention

现有技术及改进方案无法解决如下消费限制业务的场景。因为用户签约的高 QoS消费限制配额是针对某一类或是全部业务（Service A和 Service B 属于消费限制签约业务， Service C不属于），且这些业务具有相同或不同的计费费率 RG ( Service A, RGl ; Service B, RG2; Service C, RGl ) , OCS 的信用管控机制是针对 RG来下发信用配额。则当用户有多个业务同时使用 ( Service A, B, C ) ,且有些业务属于消费限制签约的业务（ Service A和 B ) , 有些不是（ Service C ) , 则 OCS收到 RGl的 CCR信用额度请求，则无法确定是否为消费限制签约业务 Service A或非消费限制签约业务 Service C, 从而无法做出正确的信用配额的决策和授权。 The prior art and the improvement solution cannot solve the scenario of the following consumption restriction service. Because the high QoS consumption limit quota subscribed by the user is for a certain type or all services (Service A and Service B belong to the consumption restriction contract service, Service C does not belong), and these services have the same or different billing rates RG ( Service A, RGl; Service B, RG2; Service C, RGl), OCS's credit management mechanism is to issue credit quotas for RG. Then, when the user has multiple services (Service A, B, C), and some services belong to the consumption restriction contract service (Service A and B), and some are not (Service C), the OCS receives the CCR credit quota of RGl. If the request is made, it is impossible to determine whether it is the consumption restriction contract service Service A or the non-consumption restriction contract service Service C, so that the correct credit quota decision and authorization cannot be made.

本发明解决的技术问题是提供一种消费限制业务的签约和执行方法及系统，使得 OCS能够准确区分签约消费限制业务，执行信用管控功能。 The technical problem solved by the present invention is to provide a contracting and executing method and system for a consumption restriction service, so that the OCS can accurately distinguish the contracted consumption restriction service and perform the credit management and control function.

架构一 Architecture one

如图 2和 3所示，该流程具体描述如下： As shown in Figures 2 and 3, the process is described as follows:

步骤 201 , IP-CAN会话创建完成， GW( PCEF )收到 hPCRF (家乡 PCRF ) 下发的 PCC规则并安装执行。当存在 BBERF时，此处同时完成网关控制会话的创建， BBERF收到 QoS规则并执行； Step 201: After the IP-CAN session is created, the GW (PCEF) receives the PCC rules issued by the hPCRF (hometown PCRF) and installs and executes them. When there is a BBERF, the gateway control session is created at the same time, and the BBERF receives the QoS rule and executes it;

步骤 202, GW ( PCEF )向 OCS发送信用控制请求消息，带上用户标识，业务信息（如业务标识 ServicelD ) , 计费信息（如费率组 Rating Group, 计费关键字 Charging key ) ； Step 202: The GW (PCEF) sends a credit control request message to the OCS, with a user identifier, service information (such as service identifier ServicelD), and charging information (such as a rate group Rating Group, a Charging key);

步骤 203 , OCS根据 OCS接收到的信息和本地签约存储的信息进行信用管控。当 OCS检测到该用户或该用户的该业务签约了消费限制，则给 GW ( PCEF )返回信用控制应答消息，消息中携带用户标识、业务信息（如业务标识 ServicelD ) , 以及模拟阔值到达指示。该模拟阔值到达指示用来指示 GW ( PCEF )该用户或该用户的该业务签约了消费限制，需要 GW ( PCEF ) 向 hPCRF发起会话修改流程，请求新的 QoS规则，并按新的 QoS规则进行信用申请和配额下发等处理； Step 203: The OCS performs credit control according to the information received by the OCS and the information stored locally. When the OCS detects that the user or the user subscribes to the consumption restriction, the GW (PCEF) returns a credit control response message, where the message carries the user identifier, the service information (such as the service identifier ServicelD), and the simulated threshold arrival indication. . The analog threshold arrival indication is used to indicate that the GW (PCEF) of the user or the user subscribes to the consumption restriction, and the GW (PCEF) is required to initiate a session modification procedure to the hPCRF, request a new QoS rule, and press the new QoS rule. Handling credit applications and quotas;

步骤 204, GW ( PCEF )收到 OCS的信用控制应答消息后，根据消息中的模拟阔值，触发 IP-CAN会话修改流程。向 PCRF发送 CCR消息申请规则更新，消息中带上用户标识、业务信息（如业务标识 Service lD ) 以及模拟阔值到达指示（即 OCS发送给 GW (PCEF )。根据需要，消息中可能会带上其它计费信息（如费率组 Rating Group ) ； Step 204: After receiving the credit control response message of the OCS, the GW (PCEF) triggers the IP-CAN session modification process according to the simulated threshold in the message. Sending a CCR message request rule update to the PCRF, the message carries the user identifier, the service information (such as the service identifier Service lD), and the analog threshold arrival indication (that is, the OCS is sent to the GW (PCEF). The message may be carried as needed. Other billing information (such as rate group);

步骤 205, hPCRF收到 PCEF发送的会话修改请求消息后，根据消息中的阔值到达指示，以及相关的业务信息，以及可能同时携带的其它计费信息，制定新的或修改 PCC/QoS规则。例如，当判断当前为消费限制业务的使用时，根据签约提升或降低 QoS; Step 205: After receiving the session modification request message sent by the PCEF, the hPCRF according to the message The threshold value arrival indication, along with related business information, and other billing information that may be carried at the same time, to formulate new or modified PCC/QoS rules. For example, when it is judged that the current use is a consumption restriction service, the QoS is upgraded or lowered according to the contract;

步骤 206, PCRF下发 IP-CAN会话修改确认消息给 GW ( PCEF ) , 消息中带上更新后的 PCC/QoS规则；若存在 GW ( BBERF )则 PCRF将触发网关控制会话修改，下发新的 QoS规则给 GW (BBERF) ； Step 206: The PCRF sends an IP-CAN session modification confirmation message to the GW (PCEF), and the message carries the updated PCC/QoS rule. If the GW (BBERF) exists, the PCRF triggers the gateway control session modification and sends a new one. QoS rules to GW (BBERF);

步骤 207, GW (PCEF)收到响应消息后安装并执行策略。如规则更新，事件触发器等； Step 207: The GW (PCEF) installs and executes the policy after receiving the response message. Such as rule updates, event triggers, etc.

步骤 208, GW (PCEF) 向 OCS重新发起信用控制请求消息。消息中带上用户标识，业务信息（如业务标识 Service ID),计费信息（如费率组 Rating Grou ) ； Step 208, the GW (PCEF) re-initiates a credit control request message to the OCS. The message carries the user identifier, service information (such as service identifier Service ID), and billing information (such as rate group rating Grou);

步骤 209, OCS根据接收到的信息和本地签约存储的信息进行信用管控。当 OCS检测到该用户或该用户的该业务签约了消费限制，且该计费策略符合消费限制签约（例如，费率组为消费限制签约时的特定值），则根据签约信息下发信用配额给 GW (PCEF) (例如，流量配额和 /或时间配额）； Step 209: The OCS performs credit management according to the received information and the information stored locally. When the OCS detects that the user or the user's service has contracted the consumption limit, and the charging policy meets the consumption restriction contract (for example, the rate group is a specific value when the consumption restriction is contracted), the credit quota is issued according to the contract information. Give GW (PCEF) (for example, traffic quotas and/or time quotas);

步骤 210, PCEF收到 OCS下发的配额，执行相关业务的用量统计，业务正常进行，按现有流程执行后续处理。 Step 210: The PCEF receives the quota issued by the OCS, performs usage statistics of related services, and performs normal operations, and performs subsequent processing according to the existing process.

UE通过步骤 201-步骤 210实现了消费限制用户业务的签约和执行。业务过程中，当 GW (PCEF)的用量统计（时长和或流量 )达到 OCS下发的配额时， GW (PCEF)会再次向 OCS发起信用控制请求，重复 208 210步骤，提供业务的后续执行与统计。直到签约的消费限制阔值到达，将执行如下步骤：步骤 301, 业务过程中， GW (PCEF) 阔值到达，发起信用控制请求消息给 OCS, 并上报用量； The UE implements the signing and execution of the consumer restricted user service through steps 201-210. During the service process, when the GW (PCEF) usage statistics (time length and or traffic) reaches the quota issued by the OCS, the GW (PCEF) will initiate a credit control request to the OCS again, repeating step 208 210 to provide subsequent execution of the service. statistics. Until the contracted consumption limit reaches, the following steps are performed: Step 301: During the business process, the GW (PCEF) threshold arrives, initiates a credit control request message to the OCS, and reports the usage;

步骤 302当 OCS检测到消费限制阔值到达（如 GW (PCEF)上报通知或是自身定时器超时等），则会发起重授权请求，进一步触发会话修改流程，更新 PCC/QoS规则，执行相应的信用控制和用量统计； Step 302: When the OCS detects the arrival of the consumption limit threshold (such as a GW (PCEF) report notification or a self-timer timeout, etc.), a re-authorization request is initiated, the session modification process is further triggered, the PCC/QoS rule is updated, and the corresponding Credit control and usage statistics;

步骤 303, OCS给 GW (PCEF)发送信用控制应答消息，消息中带上用户标识，业务信息（例如业务标识 Service ID) , 以及阔值到达指示（即消费限制业务的阔值到达标识）。根据需要，消息中可能会带上其它计费信息（如费率组 Rating Group ) ； Step 303: The OCS sends a credit control response message to the GW (PCEF), where the message carries the user identifier, the service information (such as the service identifier Service ID), and the threshold arrival indication (ie, consumption). Limit the threshold of the business to reach the logo). Other billing information (such as Rate Group) may be included in the message as needed;

步骤 304, GW ( PCEF )收到 OCS的信用控制应答消息后，根据消息中的阔值，触发 IP-CAN会话修改流程。向 hPCRF发送 CCR消息申请规则更新，消息中带上用户标识、业务信息（如业务标识 Service ID )以及阔值到达指示。根据需要，消息中可能会带上其它计费信息（如费率组 Rating Group ) ；步骤 305, hPCRF收到 GW ( PCEF )发送的会话修改请求消息后，根据消息中的阔值到达指示，以及相关的业务信息，以及可能同时携带的其它计费信息，制定新的或修改 PCC/QoS规则。例如，当判断当前为消费限制业务的停用时，根据签约降低或提升 QoS; Step 304: After receiving the credit control response message of the OCS, the GW (PCEF) triggers the IP-CAN session modification process according to the threshold in the message. The CCR message request rule is sent to the hPCRF, and the message carries the user identifier, the service information (such as the service identifier Service ID), and the threshold arrival indication. According to requirements, other charging information (such as rate group) may be carried in the message; step 305, after the hPCRF receives the session modification request message sent by the GW (PCEF), according to the threshold arrival indication in the message, and Relevant business information, as well as other billing information that may be carried at the same time, to develop new or modified PCC/QoS rules. For example, when it is determined that the current consumption restriction service is deactivated, the QoS is reduced or increased according to the contract;

步骤 306, PCRF下发 IP-CAN会话修改确认消息给 GW ( PCEF ) , 消息中带上更新后的 PCC/QoS规则；若存在 GW ( BBERF )则 PCRF将触发网关控制会话修改，提供更新后的 QoS规则给 GW ( BBERF ) ； Step 306, the PCRF sends an IP-CAN session modification confirmation message to the GW (PCEF), and the message carries the updated PCC/QoS rule; if the GW (BBERF) exists, the PCRF triggers the gateway control session modification, and provides the updated QoS rules to GW ( BBERF );

如果步骤 303中没有在信用控制应答消息中将阔值指示到达指示发送给 PCEF,则 OCS会发起一个重授权请求消息，发送相应的指示给 GW( PCEF )。则此处， GW ( PCEF )发送重授权应答消息给 OCS, 消息中携带有内部用户标识，及操作指示（例如结果码中指示业务继续并将会有新的信用控制请求发送）。如果签约消费限制业务阔值到达后终结业务，则签约操作指示为业务结束则无后续信用请求消息。则后续 307-310不再执行，相关网元按现有技术作会话终结处理，流程结束。否则继续步骤 307流程； If the wide value indication arrival indication is not sent to the PCEF in the credit control response message in step 303, the OCS will initiate a re-authorization request message and send a corresponding indication to the GW (PCEF). Here, the GW (PCEF) sends a re-authorization response message to the OCS, the message carries an internal user identity, and an operation indication (for example, the result code indicates that the service continues and a new credit control request is sent). If the contracted consumption limit service expires and the service is terminated, the contract operation instruction indicates that there is no follow-up credit request message when the service ends. Then, the subsequent 307-310 is no longer executed, and the related network element is terminated by the existing technology, and the process ends. Otherwise proceed to step 307 process;

步骤 307, GW ( PCEF )安装并执行 hPCRF下发的策略。如规则更新，事件触发器等； Step 307: The GW (PCEF) installs and executes the policy delivered by the hPCRF. Such as rule updates, event triggers, etc.

步骤 308, GW ( PCEF ) 向 OCS重新发起信用控制请求消息。消息中带上用户标识，业务信息（如业务标识 Service ID ) ,计费信息（如费率组 Rating Grou ) ； Step 308, GW (PCEF) re-initiates a credit control request message to the OCS. The message carries the user identifier, service information (such as service ID), and billing information (such as rate group rating Grou);

步骤 309, OCS根据接收到的信息和本地签约存储的信息进行信用管控。当 OCS检测到该用户或该用户的该业务签约了消费限制，但消费限制业务阔值已经到达（例如规定时间的用量使用完毕），且计费策略符合非消费限制业务签约（例如，费率组不同于消费限制策略的值），则根据签约信息下发信用配额给 GW ( PCERF ) (例如 , 流量配额和 /或时间配额 ) ； Step 309, the OCS performs credit management according to the received information and the information stored locally. When the OCS detects that the user or the user's service has contracted the consumption limit, but the consumption limit service threshold has arrived (for example, the usage of the specified time is completed), and the charging policy meets the non-consumption limit. The service contract (for example, the rate group is different from the value of the consumption restriction policy), and the credit quota is issued to the GW (PCERF) according to the contract information (for example, the traffic quota and/or the time quota);

步骤 310, PCEF收到 OCS下发的配额，执行相关业务的用量统计，业务正常进行，按现有流程执行后续处理。 In step 310, the PCEF receives the quota issued by the OCS, performs the usage statistics of the related services, and performs the normal operation, and performs subsequent processing according to the existing process.

以上步骤 201 310, 为架构 1完整的消费限制业务的签约、授权和执行，以及阔值到达后的取消并更新的流程。 The above step 201 310 is a process of signing, authorizing and executing the complete consumption restriction service of the architecture 1 and canceling and updating the process after the arrival of the threshold value.

步骤 402, GW ( PCEF )收到 IP-CAN承载建立请求，该 IP-CAN会话建立请求消息中携带用户标识和请求接入的 PDN网络的 PDN标识； Step 402: The GW (PCEF) receives an IP-CAN bearer setup request, where the IP-CAN session setup request message carries the user identifier and the PDN identifier of the PDN network requesting access;

步骤 403 , GW ( PCEF ) 向 hPCRF发起 IP-CAN会话创建指示，并在该 IP-CAN会话建立指示消息中携带用户标识、 PDN标识以及为 UE分配的 IP 地址（IP Address ) ； Step 403: The GW (PCEF) initiates an IP-CAN session creation indication to the hPCRF, 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;

步骤 404, hPCRF根据用户标识判断还没有该用户的签约数据，则向 SPR 发送签约文档请求，并在该签约文档请求中携带用户标识和 PDN标识； Step 404: The hPCRF sends a subscription document request to the SPR according to the user identifier, and the user identifier and the PDN identifier are carried in the subscription document request.

步骤 405 , SPR根据用户标识和 PDN标识返回用户签约信息（即，签约文档应答）； Step 405: The SPR returns the user subscription information according to the user identifier and the PDN identifier (ie, the contract document response);

步骤 406, 当 SPR返回的签约表明， PCRF的策略决策需要依赖于计费相关信息，且 PCRF尚未获取相关信息（例如该 IP-CAN会话为该用户和 PDN 的第一个 IP-CAN会话），则需要发起计费策略会话。 PCRF将向 OCS发送计费策略会话创建消息，消息中带上用户标识， IP地址，以及业务信息（如业务标识）； Step 406: When the subscription returned by the SPR indicates that the policy decision of the PCRF needs to depend on the charging related information, and the PCRF has not obtained the related information (for example, the IP-CAN session is the first IP-CAN session of the user and the PDN), Then you need to initiate a charging policy session. The PCRF will send an accounting policy session creation message to the OCS, with the user ID, IP address, and service information (such as service identifier) in the message;

步骤 407 , OCS根据计费策略会话创建和本地签约存储的信息进行本地查询和决策，并发送计费策略会话应答给 hPCRF。消息中带上计费相关信息。例如，当 OCS检测到该用户或该用户的该业务签约了消费限制，则消息中除了携带用户标识、业务信息（如业务标识 Service ID )夕卜，还会带上相应的签约指示 (例如消费限制业务标识或模拟阔值等）。该签约指示用来指示 PCRF 该用户或该用户的该业务签约了消费限制，需要制定相应的 PCC/QoS规则以保证该类用户或该类业务的 QoS; Step 407: The OCS performs local query and decision according to the information about the charging policy session creation and the local subscription, and sends a charging policy session response to the hPCRF. The billing information is included in the message. For example, when the OCS detects that the user or the user's service has contracted the consumption limit, the message is excluded. Carrying the user ID and service information (such as the service ID), the corresponding contract indication (such as the consumption restriction service identifier or the simulation threshold). The subscription indication is used to indicate that the user of the PCRF or the user subscribes to the consumption restriction, and the corresponding PCC/QoS rule needs to be formulated to ensure the QoS of the user or the service.

步骤 406和步骤 407, 根据实现机制需要触发，至少可包括如下几种执行方式：可在某个 UE该 PDN下的第一个 IP-CAN会话创建时执行（此时 OCS 会将该 UE所有业务的相关计费信息发送给 hPCRF ) ；可在某个 UE的每个 IP-CAN会话创建时执行（此时， PCRF可根据该业务的策略决策是否需要获取 OCS的计费信息而触发 )；可在 hPCRF和该 OCS的首次会话时执行（此类场景例如当某类计费信息为全部 UE和业务 List签约，则可以一次下发给 hPCRF作本地存储和后续本地访问。 OCS的该类计费信息更新后通知 hPCRF 更新。 )；可在某 UE的 IP-CAN会话修改过程中，策略决策需要获取该机费信息，而触发执行和 OCS的计费策略会话； The 406 and the step 407 are triggered according to the implementation mechanism, and may include at least the following implementation manners: when the first IP-CAN session under the PDN of a certain UE is created, the OCS will perform all services of the UE. The relevant charging information is sent to the hPCRF); it can be executed when each IP-CAN session of a certain UE is created (in this case, the PCRF can trigger according to whether the policy decision of the service needs to acquire the charging information of the OCS); The hPCRF and the first session of the OCS are executed. (such a scenario, for example, when a certain type of charging information is signed for all UEs and a service list, it can be sent to the hPCRF for local storage and subsequent local access at one time. After the information is updated, the hPCRF update is notified. ); In the IP-CAN session modification process of a certain UE, the policy decision needs to acquire the machine fee information, and triggers the execution of the charging policy session with the OCS;

步骤 408 , hPCRF收到 OCS的计费策略会话应答消息后，根据消息中的签约指示（例如消费限制业务标识或模拟阔值等），以及返回的其它签约信息、网络策略、 UE的接入信息等制定策略（包括 PCC规则、事件触发器等）。当判断当前为消费限制业务的使用，则会制定特殊的 PCC/QoS规则（如可提供特殊 QoS保证，授权特殊 Charging key或 Rating Grou 等）； Step 408: After receiving the charging policy session response message of the OCS, the hPCRF, according to the subscription indication in the message (for example, the consumption restriction service identifier or the simulation threshold, etc.), and the returned other subscription information, the network policy, and the access information of the UE. Etc. Develop strategies (including PCC rules, event triggers, etc.). When judging the current use of constrained services, special PCC/QoS rules are established (such as special QoS guarantees, special Charging keys or Rating Grous, etc.);

步骤 409, hPCRF向 GW ( PCEF )返回 IP-CAN会话建立确认消息，下发制定的策略； Step 409, the hPCRF returns an IP-CAN session establishment confirmation message to the GW (PCEF), and issues the formulated policy;

步骤 410, GW ( PCEF )收到响应消息后安装并执行策略，如 PCC规则、事件触发器等。并根据授权规则向 OCS发起信用控制请求消息。消息中带上用户标识，业务信息（如业务标识 Service ID ) , 计费信息（如费率组 Rating Grou ) ； In step 410, the GW (PCEF) installs and executes a policy, such as a PCC rule, an event trigger, etc., after receiving the response message. And initiating a credit control request message to the OCS according to the authorization rule. The message carries the user identifier, service information (such as service identifier Service ID), and billing information (such as rate group rating Grou);

步骤 411 , OCS根据接收到的信息和本地签约存储的信息进行信用管控。当 OCS检测到该用户或该用户的该业务签约了消费限制，且该计费策略符合消费限制签约（例如，费率组为消费限制签约时的特定值），则根据签约信息下发信用配额给 GW ( PCERF ) (例如，流量配额和 /或时间配额 ) ； Step 411: The OCS performs credit management according to the received information and the information stored locally. When the OCS detects that the user or the user's service has contracted the consumption limit, and the charging policy meets the consumption restriction contract (for example, the rate group is a specific value when the consumption restriction is contracted), the credit quota is issued according to the contract information. Give GW (PCERF) (for example, traffic quotas and/or time quotas);

步骤 412-15, 按现有结束流程执行后续处理。 GW ( PCEF )所在网关返回承载建立应答（412 ) , 携带分配的 IP地址。如果需要则可能会发起相应的承载创建处理（ 413和 414 )建立 IP-CAN会话应答。根据 OCS下发的配额执行相关业务的用量统计，业务正常进行。 In step 412-15, the subsequent processing is performed according to the existing ending process. GW (PCEF) where the gateway is located The bearer setup response (412) carries the assigned IP address. If necessary, a corresponding bearer creation process (413 and 414) may be initiated to establish an IP-CAN session response. According to the quota issued by the OCS, the usage statistics of related services are performed, and the service is normal.

UE通过步骤 401-步骤 415实现了消费限制用户业务的签约和执行。业务过程中，当 GW (PCEF)的用量统计（时长和或流量 )达到 OCS下发的配额时， GW ( PCEF )会再次向 OCS发起信用控制请求，重复 410 411 步骤，提供新的信用配额继续业务的后续执行。直到签约的消费限制阔值到达，触发会话修改流程。 The UE implements the signing and execution of the consumer restricted user service through steps 401 to 415. During the business process, when the usage statistics (time and or traffic) of the GW (PCEF) reaches the quota issued by the OCS, the GW (PCEF) will initiate a credit control request to the OCS again, repeating step 410 411 to provide a new credit quota to continue. Subsequent execution of the business. Until the contracted consumption limit reaches, the session modification process is triggered.

如图 1 ( b )架构所示， OCS可通过 Sy接口和 PCRF直接交互（如图 5 ) , 触发重授权，发起会话修改和规则更新。或者可通过 Gy接口和 GW ( PCEF ) 交互，发起重授权和会话修改流程。以下则对这两类实施作分别描述。 As shown in Figure 1 (b), the OCS can directly interact with the PCRF through the Sy interface (Figure 5), trigger re-authorization, initiate session modification, and update rules. Alternatively, the Gy interface and GW (PCEF) can interact to initiate the reauthorization and session modification process. The following two types of implementation are described separately.

如图 5, OCS通过 Sy接口和 PCRF直接交互，其执行步骤为： As shown in Figure 5, the OCS directly interacts with the PCRF through the Sy interface. The execution steps are as follows:

步骤 501 , 业务过程中，当 OCS检测到消费限制阔值到达（例如 GW ( PCEF )上报通知或是自身定时器超时等），则会发起重授权请求，进一步触发会话修改流程，更新 PCC/QoS规则，执行相应的信用控制和用量统计；步骤 502, OCS给 PCRF发送计费策略报告。消息中带上用户标识，业务信息（例如业务标识 Service ID ) , 以及阔值到达指示（即消费限制业务的阔值到达标识 )。根据需要，消息中可能会带上其它计费信息（如费率组 Rating Grou ) ； Step 501: During the service process, when the OCS detects that the consumption limit threshold arrives (for example, the GW (PCEF) report notification or the self timer expires, etc.), the re-authorization request is initiated, and the session modification process is further triggered to update the PCC/QoS. Rules, performing corresponding credit control and usage statistics; Step 502, the OCS sends a charging policy report to the PCRF. The message carries the user ID, the service information (such as the service identifier Service ID), and the threshold arrival indication (that is, the threshold arrival indication of the consumption restriction service). Other billing information (such as the rate group Rating Grou) may be included in the message as needed;

步骤 503 , PCRF收到计费策略报告后，给 OCS返回计费策略报告应答。消息中携带用户标识，及操作指示（例如结果码中指示业务继续并将会有新的信用控制请求发送）。如果签约消费限制业务阔值到达后终结业务，则签约操作指示为业务结束则无后续信用请求消息。则后续流程将不再执行，相关网元按现有技术作会话终结处理，流程结束。否则继续 S504流程； Step 503: After receiving the charging policy report, the PCRF returns a charging policy report response to the OCS. The message carries the user ID and an operation indication (for example, the result code indicates that the service continues and a new credit control request is sent). If the contracted consumption limit service expires and the service is terminated, the signing operation indication is that the service ends without a follow-up credit request message. The subsequent process will not be executed again, and the related network element is terminated by the existing technology, and the process ends. Otherwise continue the S504 process;

步骤 504 , hPCRF根据计费策略报告中的阔值到达指示，以及相关的业务信息，以及可能同时携带的其它计费信息，调整并更新 PCC/QoS规则。例如，当判断当前为消费限制业务的停用时，根据签约降低或提升 QoS; Step 504: The hPCRF adjusts and updates the PCC/QoS rule according to the threshold arrival indication in the charging policy report, and related service information, and other charging information that may be carried simultaneously. For example, when it is determined that the current consumption restriction service is deactivated, the QoS is reduced or increased according to the contract;

步骤 505, PCRF下发 PCC/QoS规则提供消息给 GW ( PCEF ) 消息中带上更新后的 PCC/QoS规则；若存在 GW ( BBERF )则 PCRF将触发网关控制会话修改，提供更新后的 QoS规则给 GW ( BBERF ) ； Step 505, the PCRF sends a PCC/QoS rule providing message to the GW (PCEF) message. The updated PCC/QoS rule; if there is GW (BBERF), the PCRF will trigger the gateway control session modification, and provide the updated QoS rule to GW (BBERF);

步骤 506, GW ( PCEF ) 收到规则提供消息后安装并执行策略更新，如 PCC规则、事件触发器等。 Step 506, the GW (PCEF) installs and executes a policy update after receiving the rule providing message, such as a PCC rule, an event trigger, and the like.

步骤 507, GW ( PCEF ) 向 OCS重新发起信用控制请求消息。消息中带上用户标识，业务信息（如业务标识 Service ID ) , 计费信息（如费率组 Rating Grou ) ； Step 507, GW (PCEF) re-initiates a credit control request message to the OCS. The message carries the user ID, service information (such as service ID), and billing information (such as rate group rating Grou);

步骤 508, OCS根据接收到的信息和本地签约存储的信息进行信用管控。当 OCS检测到该用户或该用户的该业务签约了消费限制，但消费限制业务阔值已经到达（例如规定时间的用量使用完毕），且计费策略符合非消费限制业务签约（例如，费率组不同于消费限制策略的值），则根据签约信息下发信用配额给 GW ( PCERF ) (例如 , 流量配额和 /或时间配额 ) ； Step 508: The OCS performs credit management according to the received information and the locally stored information. When the OCS detects that the user or the user's service has contracted the consumption limit, but the consumption limit service threshold has arrived (for example, the usage of the specified time is completed), and the charging policy meets the non-consumption restriction service contract (for example, the rate) The group is different from the value of the consumption restriction policy), and the credit quota is issued to the GW (PCERF) according to the contract information (for example, the traffic quota and/or the time quota);

步骤 509 , GW ( PCEF )给 hPCRF返回规则提供应答消息； Step 509: GW (PCEF) provides a response message to the hPCRF return rule.

步骤 510, GW ( PCEF )收到 OCS下发的配额，执行相关业务的用量统计，业务正常进行，按现有流程执行后续处理。 Step 510: The GW (PCEF) receives the quota issued by the OCS, performs the usage statistics of the related services, and the service is normally performed, and performs subsequent processing according to the existing process.

以上步骤 401 415和 501 510组成架构 2完整的消费限制业务的签约、授权和执行，以及阔值到达后的取消并更新的流程。 The above steps 401 415 and 501 510 form the contract, authorization and execution of the complete consumption restriction service, and the cancellation and update process after the arrival of the threshold.

如图 3 , 架构 2中， OCS通过 Gy接口和 GW ( PCEF ) 交互，更新阔值发起会话修改的处理流程和步骤，与架构 1中的相同，参见步骤 S301~S310。则步骤 401 415和 301 310组成架构 2的消费限制业务的签约、授权和执行，以及阔值到达后的取消并更新的另一完成流程。 As shown in Figure 3, in the architecture 2, the OCS interacts with the GW (PCEF) through the Gy interface to update the threshold. The process and steps for initiating the session modification are the same as those in the architecture 1. See steps S301 to S310. Then steps 401 415 and 301 310 constitute the signing, authorization and execution of the consumption restriction service of the architecture 2, and another completion process of canceling and updating the threshold after arrival.

现有技术的改进方案中 OCS给 PCEF返回的新的参数标识是模拟阔值到达情形，并触发会话修改更新相关规则，重用了现有实现架构的流程。存在重鉴权交互及会话修改流程等冗余消息和处理。本发明实施例二克服了上述缺陷。 In the prior art improvement scheme, the new parameter identifier returned by the OCS to the PCEF is an analog threshold arrival situation, and triggers the session modification update related rule, and reuses the process of the existing implementation architecture. There are redundant messages and processing such as re-authentication interaction and session modification process. Embodiment 2 of the present invention overcomes the above drawbacks.
