Description

策略和计费控制方法及设备技术领域 Strategy and charging control method and device

本发明实施例涉及通信技术领域，并且更具体地，涉及策略和计费控制方法及设备。背景技术 Embodiments of the present invention relate to the field of communication technologies, and, more particularly, to a policy and charging control method and apparatus. Background technique

3GPP ( 3rd Generation Partnership Project, 第三代伙伴计划）的 PCC ( Policy and Charging Control, 策略和计费控制）架构提供了基于业务数据流的策略控制和计费控制功能。 PCC***的逻辑架构包括 PCRF ( Policy and Charging Rules Function,策略和计费规则功能）和 PCEF( Policy and Charging Enforcement Function, 策略和计费执行功能）等。 The 3GPP (3rd Generation Partnership Project) PCC (Policy and Charging Control) architecture provides policy control and charging control based on traffic data flow. The logical architecture of the PCC system includes the PCRF (Policy and Charging Rules Function) and the PCEF (Policy and Charging Enforcement Function).

PCRF的主要功能是向网关下发 PCC规则（ PCC Rule ), PCC Rule包括策略和计费信息。网关包括 GGSN ( (Gateway General Packet Radio Service Support Node,网关通用分组无线服务支持节点）、 PGW( Packet Data Network Gateway, 分组数据网络网关）、 SGW ( Serving Gateway, 服务网关）等。 The main function of the PCRF is to deliver a PCC Rule (PCC Rule) to the gateway. The PCC Rule includes policy and charging information. The gateway includes a GGSN (Gateway General Packet Radio Service Support Node), a PGW (Packet Data Network Gateway), an SGW (Serving Gateway), and the like.

PCEF位于移动分组网络中移动网关的功能实体，如对应 SAE ( System Architecture Evolution, ***架构演进）网络中的网关 PGW或 2G/3G网络中的网关 GGSN, 也可以独立部署。 The PCEF is a functional entity of the mobile gateway in the mobile packet network. For example, the gateway PGW in the network architecture of the SAE (System Architecture Evolution) network or the gateway GGSN in the 2G/3G network can also be deployed independently.

PCEF功能可以实现业务级的 QoS ( Quality of Service , 服务质量）控制和计费，并可以动态调整策略。 The PCEF function implements service-level QoS (Quality of Service) control and accounting, and can dynamically adjust policies.

PCEF与 PCRF之间通过 Gx接***互。 PCEF收到建立 IP-CAN( Internet Protocol-Connectivity Access Network ，因特网协议连接性接入网络）会话建立或者修改请求之后，向 PCRF发送 CCR ( Credit-Control-Request, 信用控制请求）消息，请求 PCC策略。 The PCEF interacts with the PCRF through the Gx interface. After receiving the IP-CAN (Internet Protocol-Connectivity Access Network) session establishment or modification request, the PCEF sends a CCR (Cash-Control-Request) message to the PCRF to request a PCC policy. .

PCRF根据用户请求信息，以及从 SPR ( Subscription Profile Repository, 用户属性存储器）获取的用户签约信息，或者从 AF ( Application Function, 应用功能 )获取的更新的业务流信息，确定 PCC Rule。 The PCRF determines the PCC Rule based on the user request information, the user subscription information acquired from the SPR (Subscription Profile Repository), or the updated service flow information obtained from the AF (Application Function).

PCRF # PCC Rule通过 Diameter CCA( Diameter Credit-Control- Answer , 直径信用控制响应）消息或者 Diameter RAR(Re-Auth-Reuqest, 重鉴权请求）消息发送给 PCEF, 使用 Gx接口中的下列 AVP ( Attribute Value Pair, 属性值对）。 The PCRF #PCC Rule is sent to the PCEF through the Diameter CCA (Dimeter Credit-Control- Answer) message or the Diameter RAR (Re-Auth-Reuqest) message. The following AVPs in the Gx interface are used. Value Pair, attribute Value pair).

一个 PCC Rule包含一个规则名称（ Rule Name )以及用户面检测的业务数据流过滤器（Service data flow filter ), 记费 (Charging)和策略控制 (Policy control)三个部分。 A PCC Rule contains a rule name (Routine Name) and a user data detection filter (Service data flow filter), Charging and Policy control.

PCEF安装、修改或者删除 PCRF提供的 PCC Rule, 并根据 PCC Rule 执行授权的计费、策略控制。 The PCEF installs, modifies or deletes the PCC Rule provided by the PCRF and performs authorized charging and policy control according to the PCC Rule.

现有 3GPP规范只定义了与三 /四层（也可称为 TCP/IP层或 L3/4 )信息对应的 PCC规则。对于七层（也可称为应用层或 L7 ) 的 PCC规则， 3GPP 规范没有给出具体的定义，只说明 PCRF可以下发 PCEF上自定义的预定义规则来实现 L7的 PCC规则。 The existing 3GPP specifications only define PCC rules corresponding to Layer 3/4 (also known as TCP/IP layer or L3/4) information. For the PCC rules of the seven-layer (also called application layer or L7), the 3GPP specification does not give a specific definition. It only shows that the PCRF can deliver custom pre-defined rules on PCEF to implement the PCC rules of L7.

一种实现方式是， PCEF上自定义 L7预定义规则（Rule ), 每个规则由 One way to achieve this is to customize the L7 predefined rules (Rule) on the PCEF, each rule by

L3/4过滤器和 L7过滤器（如 URL )组成，每个规则 L3/4和 L7都有唯一的一个计费和 /或策略控制。 L3/4 filter and L7 filter (such as URL), each rule L3/4 and L7 have unique A billing and / or policy control.

当 PCEF收到用户数据报文时，要按照规则优先级从高到底依次进行匹配。如果高优先级规则的 L3/4或 L7匹配失败，则 PCEF继续匹配低优先级的规则，直到匹配成功，从匹配成功的规则获取相应的计费和 /或控制策略。 When the PCEF receives the user data packet, it matches the rule priority from high to low. If the L3/4 or L7 match of the high priority rule fails, the PCEF continues to match the low priority rule until the match is successful, and the corresponding charging and/or control policy is obtained from the successfully matched rule.

从以上描述来看， PCEF将用户数据报文与 PCEF上自定义的 PCC规则进行匹配时，最坏的情况下如果是匹配到最低优先级的 PCC规则，则 PCEF 要先遍历匹配所有其他高优先级的 PCC规则，这对 PCEF的性能有极大的影响。 From the above description, when the PCEF matches the user data packet with the customized PCC rule on the PCEF, in the worst case, if it matches the lowest priority PCC rule, the PCEF must traverse all other high priority first. Level PCC rules, which have a great impact on the performance of PCEF.

另外，因为每个 PCC规则都有唯一的计费和 /或控制策略，相同的业务数据流需要为不同的用户定义不同的计费和 /或控制策略，即必须定义不同的规则。这样会导致规则的个数显著增加，增加了维护成本，性能消耗也会增加，不能灵活地满足不同业务场景的需求。发明内容 In addition, because each PCC rule has a unique charging and/or control policy, the same traffic data flow needs to define different charging and/or control policies for different users, ie different rules must be defined. This will result in a significant increase in the number of rules, increased maintenance costs, and increased performance consumption. It is not flexible enough to meet the needs of different business scenarios. Summary of the invention

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without making creative labor are within the scope of the present invention.

图 1是本发明一个实施例的策略和计费控制方法的流程图。图 1的方法由 PCEF设备执行。 PCEF设备是用于实现 PCEF功能的实体，如 PGW、 GGSN 或独立部署的 PCEF设备。本发明实施例对 PCEF设备的具体形式不作限制。 1 is a flow chart of a policy and charging control method in accordance with an embodiment of the present invention. The method of Figure 1 is performed by a PCEF device. A PCEF device is an entity used to implement PCEF functions, such as a PGW, a GGSN, or a separately deployed PCEF device. The specific form of the PCEF device is not limited in the embodiment of the present invention.

101，在接收到业务数据流时，将业务数据流与预定义 PCC规则进行匹配，其中预定义 PCC规则包括至少一个业务策略，每个业务策略具有相应的业务策略名称和业务策略参数。 101. When receiving the service data flow, the service data flow is matched with the predefined PCC rule, where the predefined PCC rule includes at least one service policy, and each service policy has a corresponding service policy name and a service policy parameter.

业务数据流与预定义 PCC规则的匹配过程，是指将业务数据流与预定义 PCC规则的业务数据流过滤器进行对比，以得到匹配的预定义 PCC规则。 The matching process between the service data flow and the predefined PCC rule refers to comparing the service data flow with the service data flow filter of the predefined PCC rule to obtain a matched predefined PCC rule.

102, 从与业务数据流相匹配的预定义 PCC规则所包括的至少一个业务策略中确定第一业务策略。 102. Determine a first service policy from at least one service policy included in a predefined PCC rule that matches a service data flow.

103 , 根据第一业务策略对应的业务策略参数对业务数据流进行策略或计费控制。 103. Perform policy or charging control on the service data flow according to the service policy parameter corresponding to the first service policy.

本发明实施例中，与业务数据流进行匹配的预定义 PCC规则包括至少一个业务策略，通过业务策略名称标识每个业务策略，而无需 PCC规则和业务策略——对应，这样能够减少 PCC规则的数目。 In the embodiment of the present invention, the predefined PCC rule that matches the service data flow includes at least one service policy, and each service policy is identified by the service policy name, without the PCC rule and the service policy-corresponding, which can reduce the PCC rule. number.

另外，从该至少一个业务策略中确定用于对业务数据流进行策略或计费控制的业务策略，这样，相同业务的业务数据流可以使用不同的业务策略，能够灵活地满足不同业务场景的需求。 In addition, a service policy for performing policy or charging control on the service data flow is determined from the at least one service policy, so that the service data flow of the same service may use different service policies. Ability to flexibly meet the needs of different business scenarios.

预定义 PCC规则是 PCEF设备上预先定义并存储的 PCC规则，可选地，作为一个实施例，预定义 PCC规则可包括至少一个业务策略列表，每个业务策略列表用于指示一个或多个业务策略。预定义 PCC规则可以由以下几项组成：规则名称（ Rule Name ), 用于业务数据流检测的过滤器（ Filter )、优先级和业务策略列表（Policy List )等。例如，可以对 L3/4过滤器和 L7 过滤器分别定义一个业务策略列表。 The predefined PCC rules are pre-defined and stored PCC rules on the PCEF device. Optionally, as an embodiment, the predefined PCC rules may include at least one service policy list, where each service policy list is used to indicate one or more services. Strategy. Predefined PCC rules can be composed of the following: Rule Name, Filter for Business Data Flow Detection, Priority, and Policy List. For example, you can define a separate list of business policies for L3/4 filters and L7 filters.

图 2是本发明一个实施例的预定义 PCC规则的数据结构的示意图。应注意，图 2的预定义 PCC规则只是一个非限制性的例子，而非限制本发明实施例的范围。 2 is a schematic diagram of a data structure of a predefined PCC rule in accordance with an embodiment of the present invention. It should be noted that the predefined PCC rules of Figure 2 are only a non-limiting example and are not intended to limit the scope of the embodiments of the present invention.

如图 2所示的预定义 PCC规则 200的规则名称 201为 Rulel ,包括 L3/4 过滤器 202a和 L7过滤器 202b。本发明实施例对过滤器的类型和数目不作限制。例如，本发明实施例的 PCC规则也可以仅包括 L3/4过滤器 202a或者仅包括 L7过滤器 202b。 The rule name 201 of the predefined PCC rule 200 shown in Fig. 2 is Rulel and includes an L3/4 filter 202a and an L7 filter 202b. The embodiment of the present invention does not limit the type and number of filters. For example, the PCC rules of the embodiments of the present invention may also include only the L3/4 filter 202a or only the L7 filter 202b.

L3/4过滤、器 202a对应多条业务策略 204a, 204b和 204c, 这些业务策略可以由业务策略列表 203a指定。 L7过滤器 202b对应多条业务策略 204d、 The L3/4 filter 202a corresponds to a plurality of service policies 204a, 204b and 204c, which can be specified by the service policy list 203a. The L7 filter 202b corresponds to a plurality of service policies 204d,

204e和 204f，这些业务策略可以由业务策略列表 203b指定。业务策略列表是一个或多个业务策略的集合。业务策略列表 203a和业务策略列表 203b可以是单独的对应于过滤器的列表的形式；也可以合并为一个表，在表项中增加业务策略所对应的过滤器的信息。或者，可以从预定义 PCC规则 200 中取消业务策略列表 203a和 203b, 建立过滤器和业务策略的直接对应关系。下文中将业务策略 204a-f统称为业务策略 204。 204e and 204f, these business policies can be specified by the business policy list 203b. A business policy list is a collection of one or more business policies. The business policy list 203a and the business policy list 203b may be in the form of a separate list corresponding to the filter; or may be combined into one table in which the information of the filter corresponding to the business policy is added. Alternatively, the business policy lists 203a and 203b may be canceled from the predefined PCC rules 200 to establish a direct correspondence between the filters and the business policies. The business policies 204a-f are collectively referred to below as business policies 204.

如图 2所示，业务策略 204a、 204b和 204c的名称分别为 Policyl、 Policy2 和 Policy3, 业务策略 204d、 204e和 204f的名称分别为 Policy4、 Policy5和 Policy3。也就是说，业务策略列表 203a和业务策略列表 203b可能均包含名称为 Policy3的业务策略，分别为业务策略 204c和 204f, 即业务策略 204c 和 204f是相同的业务策略。 As shown in Figure 2, the business policies 204a, 204b, and 204c are named Policyl, Policy2, and Policy3, respectively, and the business policies 204d, 204e, and 204f are named Policy4, Policy5, and Policy3, respectively. That is, the service policy list 203a and the service policy list 203b may each contain a service policy named Policy3, which is a service policy 204c and 204f, that is, the service policies 204c and 204f are the same service policy.

业务策略 204定义业务策略参数，即计费和控制策略相关参数，如优先级、门控（Gating )、计费相关的参数、 QoS相关的参数、测量相关的参数等。每个业务策略唯一的由业务策略名称（Policy Name )标识。因此，每个业务策略可以由以下几项组成：业务策略名称、优先级、门控、计费相关的参数、 QoS相关的参数、测量相关的参数等。 The business policy 204 defines the business policy parameters, that is, the charging and control policy related parameters, such as priority, Gating, charging related parameters, QoS related parameters, measurement related parameters, and the like. Each business policy is uniquely identified by a business policy name (Policy Name). Therefore, each business policy can be composed of the following items: business policy name, priority, gating, billing related parameters, QoS related parameters, measurement related parameters, etc.

本发明实施例的业务策略通过业务策略名称来标识，而不需要与 PCC 规则——对应，并且通过业务策略列表来指示同一条预定义 PCC规则内包括的一个或多个业务策略。这样，即使对于同一业务流，也可以使用不同的业务策略，例如对不同的用户可使用不同的业务策略，增强了策略控制的灵活性。 The service policy of the embodiment of the present invention is identified by the service policy name, and does not need to correspond to the PCC rule, and indicates one or more service policies included in the same predefined PCC rule through the service policy list. In this way, even for the same service flow, different service policies can be used, for example, different business policies can be used for different users, and the flexibility of policy control is enhanced.

另外，本发明实施例也便于配置和维护 PCC规则。例如，如果需要为某一 PCC规则增加业务策略，则可以修改图 2所示的数据结构，增加业务策略并修改相应的业务策略列表。同样地，如果需要删除业务策略，则可以修改图 2所示的数据结构，删除某一业务策略并修改相应的业务策略列表。这样，本发明实施例无需增加新的 PCC规则，筒化了预定义 PCC规则的配置，实现了预定义 PCC规则中业务数据流的检测过滤器和计费控制策略的分离。 In addition, embodiments of the present invention also facilitate configuration and maintenance of PCC rules. For example, if you need to add a service policy to a PCC rule, you can modify the data structure shown in Figure 2, add a service policy, and modify the corresponding service policy list. Similarly, if you need to delete a service policy, you can modify the data structure shown in Figure 2, delete a service policy, and modify the corresponding service policy list. In this way, the embodiment of the present invention does not need to add a new PCC rule, and the configuration of the predefined PCC rule is implemented, and the separation of the detection filter and the charging control policy of the service data flow in the predefined PCC rule is realized.

预定义 PCC规则可以由管理员在 PCEF和 PCRF上同时进行配置。或者，也可以通过网管中心对 PCEF和 PCRF上的预定义 PCC规则的配置信息进行同步。或者，也可以由 PCEF和 PCRF互相同步预定义 PCC规则的配置信息。例如， PCEF可以将预定义 PCC规则的配置信息通知给 PCRF。该通知过程可以在预定义 PCC规则的初始设置之后执行，也可以在预定义 PCC规则的每次更新操作之后执行，或者可以周期性地执行。 Predefined PCC rules can be configured simultaneously by the administrator on both PCEF and PCRF. Alternatively, the configuration information of the predefined PCC rules on the PCEF and PCRF can be synchronized through the network management center. Alternatively, the configuration information of the PCC rule may be predefined by the mutual synchronization of the PCEF and the PCRF. For example, the PCEF can notify the PCRF of the configuration information of the predefined PCC rules. The notification process may be performed after the initial setting of the predefined PCC rules, or after each update operation of the predefined PCC rules, or may be performed periodically.

另外， PCRF上配置的预定义 PCC规则可以是完整的，即与 PCEF上配置的预定义 PCC规则相同；也可以仅仅包括预定义 PCC规则的关键信息，例如预定义 PCC规则的规则名称、含义以及所包括的业务策略等。 In addition, the predefined PCC rules configured on the PCRF may be complete, that is, the same as the predefined PCC rules configured on the PCEF; or may include only key information of the predefined PCC rules, such as the rule name, meaning, and meaning of the predefined PCC rules. Business strategies included, etc.

可选地，作为一个实施例，在步骤 102中， PCEF设备可在收到用户的业务报文后，自己确定第一业务策略，例如将至少一个业务策略中的缺省业务策略确定为第一业务策略。或者， PCEF设备可以在收到用户的业务报文后，获知用户信息，如用户的 APN ( Access Point Name, 接入点名称）、用户的 ULI ( User Location Information, 用户位置信息）、用户的漫游状态以及用户的 QoS等；然后 PCEF根据 PCEF上的相关配置，基于用户信息决策使用匹配的预定义 PCC规则所包括的某一个业务策略作为第一业务策略。 Optionally, as an embodiment, in step 102, the PCEF device may determine the first service policy by itself after receiving the service packet of the user, for example, determining the default service policy in the at least one service policy as the first Business strategy. Alternatively, the PCEF device can obtain the user information after receiving the service packet of the user, such as the user's APN (Access Point Name), the user's ULI (User Location Information), and the user's roaming. The status and the QoS of the user, etc.; then, based on the relevant configuration on the PCEF, the PCEF uses one of the service policies included in the matched predefined PCC rules as the first service policy based on the user information decision.

可选地，作为另一实施例，在 PCEF设备能够通过本地配置等方法实现部分 PCRF功能的场景下，也可以在 PCEF设备本地指定 PCC规则的对应业务策略。例如，在接收到 PCRF的 PCC规则安装信息并根据 PCC规则安装信息安装预定义 PCC规则之后， PCEF可获知用户信息（如上述 APN、 ULI、漫游状态或 QoS等 ),并根据用户信息确定所安装的预定义 PCC规则的对应业务策略。这样， PCEF可以在根据 PCRF的指示安装预定义 PCC规则时确定所安装的预定义 PCC规则的对应业务策略。然后在步骤 102中，将步骤 101中得到的匹配业务数据流的预定义 PCC规则的对应业务策略作为第一业务策略。 Optionally, as another embodiment, in a scenario where the PCEF device can implement a partial PCRF function by using a local configuration or the like, the corresponding industry of the PCC rule may also be specified locally in the PCEF device. Business strategy. For example, after receiving the PCC rule installation information of the PCRF and installing the predefined PCC rule according to the PCC rule installation information, the PCEF can learn the user information (such as the above APN, ULI, roaming status or QoS, etc.), and determine the installed according to the user information. The corresponding business strategy for the predefined PCC rules. In this way, the PCEF can determine the corresponding service policy of the installed predefined PCC rule when installing the predefined PCC rule according to the indication of the PCRF. Then, in step 102, the corresponding service policy of the predefined PCC rule of the matching service data flow obtained in step 101 is used as the first service policy.

可选地，作为一个实施例， PCEF设备可根据 PCRF设备的指定，确定需安装的预定义 PCC规则的对应业务策略。具体地，在步骤 101之前， PCEF 设备可以接收 PCRF设备发送的 PCC规则安装信息和策略指定信息， PCC 规则安装信息用于指示安装预定义 PCC规则，策略指定信息用于指定至少一个业务策略名称。 Optionally, as an embodiment, the PCEF device may determine, according to the designation of the PCRF device, a corresponding service policy of a predefined PCC rule to be installed. Specifically, before step 101, the PCEF device may receive PCC rule installation information and policy designation information sent by the PCRF device, the PCC rule installation information is used to indicate installation of a predefined PCC rule, and the policy designation information is used to specify at least one service policy name.

PCRF设备可以在接收到 PCEF设备发送的用户 IP-CAN会话建立请求或更新请求时或者 PCRF主动触发通知 PCEF重鉴权时，发送 PCC规则安装信息和策略指定信息。但本发明实施例对 PCRF激活预定义 PCC规则的触发消息不作限制，例如该触发消息也可以是新增的专用消息。 The PCRF device may send PCC rule installation information and policy designation information when receiving the user IP-CAN session establishment request or update request sent by the PCEF device or when the PCRF actively triggers the PCEF re-authentication. However, the embodiment of the present invention does not limit the triggering message of the PCRF to activate the predefined PCC rule. For example, the trigger message may also be a new dedicated message.

PCC规则安装信息一般由 Charging-Rule-Install (计费规则安装 ) AVP 携带。该 Charging-Rule-Install AVP可以通过 Diameter CCA消息或 Diameter RAR ( Re-Auth-Request, 重新鉴权请求）消息发送。但本发明实施例对携带 PCC规则安装信息的 AVP或消息的具体形式不作限制。 The PCC rule installation information is generally carried by the Charging-Rule-Install AVP. The Charging-Rule-Install AVP can be sent through a Diameter CCA message or a Diameter RAR (Re-Auth-Request) message. However, the embodiment of the present invention does not limit the specific form of the AVP or message carrying the PCC rule installation information.

具体地，本发明实施例可以扩展 Gx接口信元，新增业务策略列表和 / 或业务策略名称，由 PCRF指定预定义 PCC规则的对应业务策略。例如， PCRF激活 PCEF上预定义的 PCC规则，同时还要指定 PCEF上预定义的业务策略。针对相同业务数据流， PCRF可激活相同的预定义 PCC规则名称，但是指定不同的业务策略名称，即可以实现针对相同业务数据流提供不同的计费与控制。 Specifically, the embodiment of the present invention can extend the Gx interface cell, add a service policy list and/or a service policy name, and the PCRF specifies a corresponding service policy of the predefined PCC rule. For example, the PCRF activates predefined PCC rules on the PCEF and also specifies predefined business policies on the PCEF. For the same service data flow, the PCRF can activate the same predefined PCC rule name, but specify different service policy names, which can provide different charging and control for the same service data flow.

PCEF设备可将策略指定信息所指定的至少一个业务策略名称与 PCC规则安装信息指示安装的预定义 PCC规则所包括的至少一个业务策略的业务策略名称进行匹配，以得到 PCC规则安装信息指示安装的预定义 PCC规则的对应业务策略。 The PCEF device may match the at least one service policy name specified by the policy designation information with the service policy name of the at least one service policy included in the pre-defined PCC rule that the PCC rule installation information indicates, to obtain the PCC rule installation information indicating installation. Predefine the corresponding business policy of the PCC rule.

具体地， PCEF设备可以比较策略指定信息所指定的至少一个业务策略名称组成的第一集合，以及 PCC规则安装信息指示安装的预定义 PCC规则所包括的至少一个业务策略的业务策略名称组成的第二集合（例如该匹配的预定义 PCC规则中的业务策略列表），得到的交集即为匹配结果。 Specifically, the PCEF device can compare at least one service policy specified by the policy designation information. a first set of name components, and a PCC rule installation information indicating a second set of business policy names of at least one business policy included in the installed predefined PCC rules (eg, a list of business policies in the matched predefined PCC rules) , the resulting intersection is the matching result.

例如，如果匹配得到一个业务策略（上述第一集合和第二集合的交集仅有一个元素），则将所述一个业务策略确定为对应业务策略。 For example, if the matching obtains a business policy (the intersection of the first set and the second set has only one element), the one business policy is determined as the corresponding business policy.

或者，如果匹配得到多个业务策略（上述第一集合和第二集合的交集有多个元素），则选择多个业务策略之一作为对应业务策略。例如可按照多个业务策略的优先级，选择多个业务策略之一作为对应业务策略，如选择优先级最高的业务策略。 Alternatively, if the matching obtains multiple service policies (the intersection of the first set and the second set has multiple elements), one of the multiple business policies is selected as the corresponding business policy. For example, one of the multiple service policies may be selected as the corresponding service policy according to the priority of multiple service policies, for example, the service policy with the highest priority is selected.

或者，如杲没有匹配到业务策略（上述第一集合和第二集合没有交集），则将至少一个业务策略中的缺省业务策略确定为对应业务策略，或者可以确定匹配失败。 Or, if the service policy is not matched (the first set and the second set have no intersection), the default service policy in the at least one service policy is determined as the corresponding service policy, or the matching failure may be determined.

可选地，作为另一实施例， PCRF 发送的策略指定信息可以在 Charging-Rule-Install AVP 中携带。或者，可以在 Diameter CCA 消息或 Diameter RAR消息中新增 AVP携带策略指定信息。本发明实施例对携带策略指定信息的消息或 AVP的具体形式不作限制。 Optionally, as another embodiment, the policy specifying information sent by the PCRF may be carried in the Charging-Rule-Install AVP. Alternatively, AVP carrying policy designation information may be added to the Diameter CCA message or the Diameter RAR message. The embodiment of the present invention does not limit the specific form of the message or the AVP carrying the policy designation information.

图 3是本发明另一实施例的策略和计费控制方法的流程图。图 3的方法由 PCRF设备执行。 PCRF设备可以是独立部署的设备，也可以由 PGW或 GGSN等网元来实现部分 PCRF功能。本发明实施例对 PCRF设备的具体形式不作限制。 3 is a flow chart of a policy and charging control method according to another embodiment of the present invention. The method of Figure 3 is performed by a PCRF device. The PCRF device can be an independently deployed device, or a partial PCRF function can be implemented by a network element such as a PGW or a GGSN. The specific form of the PCRF device is not limited in the embodiment of the present invention.

301 ,确定用户的预定义 PCC规则和对应于该预定义 PCC规则的第一业务策略。 301. Determine a predefined PCC rule of the user and a first service policy corresponding to the predefined PCC rule.

本发明实施例对步骤 301的触发消息不作限制，例如该触发消息可以是用户 IP-CAN会话建立请求或更新请求，或者是新增的专用消息。 The embodiment of the present invention does not limit the trigger message of step 301. For example, the trigger message may be a user IP-CAN session establishment request or an update request, or a new dedicated message.

可选地，作为一个实施例， PCRF可根据用户信息（如上述 APN、 ULI、漫游状态或 QoS等），确定用户的预定义 PCC规则和对应的第一业务策略。 Optionally, as an embodiment, the PCRF may determine a predefined PCC rule of the user and a corresponding first service policy according to user information (such as the foregoing APN, ULI, roaming status, or QoS, etc.).

302, 向 PCEF设备发送 PCC规则安装信息和策略指定信息。 PCC规则安装信息用于指示在 PCEF上安装预定义 PCC规则。预定义 PCC规则可包括业务策略列表，业务策略列表用于指示预定义 PCC规则所包括的至少一个业务策略。策略指定信息用于指定第一业务策略的业务策略名称。 302. Send PCC rule installation information and policy designation information to the PCEF device. PCC Rules Installation information is used to indicate the installation of predefined PCC rules on the PCEF. The predefined PCC rules may include a list of business policies, and the business policy list is used to indicate at least one business policy included in the predefined PCC rules. The policy specification information is used to specify the business policy name of the first business policy.

本发明实施例中，与业务数据流进行匹配的预定义 PCC规则包括至少一个业务策略，通过业务策略名称标识每个业务策略，而无需 PCC规则和业务策略——对应，这样能够减少 PCC规则的数目。 In the embodiment of the present invention, the predefined PCC rules matching the service data flow include at least A business policy identifies each business policy by its business policy name without the need for PCC rules and business policies—corresponding to reduce the number of PCC rules.

另外，从该至少一个业务策略中确定用于对业务数据流进行策略或计费控制的业务策略，这样，相同业务的业务数据流可以使用不同的业务策略，能够灵活地满足不同业务场景的需求。 In addition, a service policy for performing policy or charging control on the service data flow is determined from the at least one service policy, so that the service data flow of the same service can use different service policies, and can flexibly meet the requirements of different service scenarios. .

可选地，作为一个实施例， PCRF设备在向 PCEF设备发送策略指定信息时，可向 PCEF设备发送 Charging-Rule-Install AVP，其中携带策略指定信息；或者，向 PCEF设备发送 Diameter CCA消息，其中携带策略指定信息；或者，向 PCEF设备发送 Diameter RAR消息，其中携带策略指定信息。 Optionally, as an embodiment, the PCRF device may send a Charging-Rule-Install AVP to the PCEF device, where the policy information is carried, or send a Diameter CCA message to the PCEF device, where the PCRF device sends the policy designation information to the PCEF device, where Carrying the policy designation information; or sending a Diameter RAR message to the PCEF device, where the policy designation information is carried.

下面结合具体例子，更加详细地描述本发明的实施例。 Embodiments of the present invention are described in more detail below with reference to specific examples.

图 4是本发明另一实施例的策略和计费控制过程的流程图。图 4的实施例中，扩展 Charging-Rule-Install AVP携带策略指定信息。 4 is a flow chart of a policy and charging control process in accordance with another embodiment of the present invention. In the embodiment of Figure 4, the extended Charging-Rule-Install AVP carries policy designation information.

401 , 进行业务规划， PCEF和 PCRF配置预定义 PCC规则。例如，建立如图 2所示的预定义 PCC规则。 401. Perform business planning, PCEF and PCRF to configure predefined PCC rules. For example, create a predefined PCC rule as shown in Figure 2.

应注意， PCRF上配置的预定义 PCC规则可以是完整的，也可以仅包括预定义 PCC规则的关键信息。 It should be noted that the predefined PCC rules configured on the PCRF may be complete or may only include key information of predefined PCC rules.

402, 在 IP-CAN会话建立或修改过程中， PCEF向 PCRF分别发送针对特定用户 Userl 和 User2 的请求，请求相应的 PCC 策略。该请求可以由 Diameter CCR消息携带。 402. During the establishment or modification of the IP-CAN session, the PCEF sends a request for the specific users Userl and User2 to the PCRF to request the corresponding PCC policy. The request can be carried by a Diameter CCR message.

本发明实施例对用户的数目不作限制。对于每个用户，均单独执行步骤 The embodiment of the present invention does not limit the number of users. Steps are performed separately for each user

402和 403。 402 and 403.

403， PCRF向 PCEF发送 Diameter CCA消息。 403. The PCRF sends a Diameter CCA message to the PCEF.

该 Diameter CCA消息中携带扩展的 Charging-Rule-Install AVP, 指示安装 PCC规则并按照策略指定信息指定的业务策略名称定义计费和 /或控制策略执行相应的处理。 The Diameter CCA message carries an extended Charging-Rule-Install AVP, which indicates that the PCC rule is installed and the charging and/or control policy is defined according to the business policy name specified by the policy specifying information to perform corresponding processing.

可选地，如果 Charging-Rule-Install下发 PCC预定义规则时没有包括新增的 AVP, 则预定义 PCC规则按照缺省的计费和 /控制策略名进行处理。 Optionally, if the Charging-Rule-Install sends a PCC predefined rule without including the newly added AVP, the predefined PCC rule is processed according to the default charging and/or control policy name.

以下是扩展 Charging-Rule-Install AVP 的一个具体实现，新增字段 Policy-Name指示预定义 PCC规则对应的策略名称。具体实现中，携带策略指定信息的 AVP 的名称、数据类型都可以具体定义，只要表示相同含义即可，本发明实施例对此不作限制。 Charging-Rule-Install：: = < AVP Header: 1001 > The following is a specific implementation of the extended Charging-Rule-Install AVP. The new field Policy-Name indicates the policy name corresponding to the predefined PCC rule. In a specific implementation, the name and the data type of the AVP carrying the policy designation information may be specifically defined, as long as the same meaning is indicated, which is not limited by the embodiment of the present invention. Charging-Rule-Install:: = < AVP Header: 1001 >

*[ Charging-Rule-Definition ] *[ Charging-Rule-Definition ]

*[ Charging-Rule-Name ] *[ Charging-Rule-Name ]

*[ Charging-Rule-Base-Name ] *[ Charging-Rule-Base-Name ]

...... ......

*[ Policy-Name] *[ Policy-Name]

*[ AVP ] *[ AVP ]

上述例子中，符号 *表示相应的 AVP可以有多个。由 Charging-Rule-Name 指定 PCEF需要安装的规则名称，由 Policy-Name指定相应的业务策略名称。这种情况下，一个 Charging-Rule-Name可以仅对应于一个 Policy-Name。 In the above example, the symbol * indicates that there may be more than one corresponding AVP. The name of the rule to be installed by PCEF is specified by Charging-Rule-Name, and the corresponding business policy name is specified by Policy-Name. In this case, a Charging-Rule-Name can correspond to only one Policy-Name.

另夕卜，作为另一实施例， Charging-Rule-Install 中也可以由 Charging-Rule-Base-Name指定规则组的名称。一个规则组可以包括一个或多个 PCC规则。这种情况下，一个 Charging-Rule-Base-Name可以对应于一个或多个 Policy- Name In addition, as another embodiment, Charging-Rule-Install may also specify the name of the rule group by Charging-Rule-Base-Name. A rule group can include one or more PCC rules. In this case, a Charging-Rule-Base-Name can correspond to one or more Policy- Names.

这样， PCEF确定了特定用户适用的 PCC规则，并且确定了每个 PCC 规则相应的业务策略名称。 Thus, the PCEF determines the PCC rules applicable to a particular user and determines the corresponding business policy name for each PCC rule.

假设在步驟 403中确定对于特定用户 Userl , 指示安装 PCC规则 Rulel (对应于业务策略 Policyl )、 Rule2 (对应于业务策略 Policy2 )和 Rule3 (对应于业务策略 Policy3 )。另外，假设在步骤 403中确定对于特定用户 User2, 指示安装 PCC规则 Rulel (对应于业务策略 Policyl ), Rule2 (对应于业务策略 Policy4 )和 Rule4 (对应于业务策略 Policy5 )。每个 PCC规则可以对应特定的业务数据流。但本发明实施例对步驟 403确定的 PCC规则的数目不作限制。 Assume in step 403 that it is determined for the specific user User1 that the PCC rules Rulel (corresponding to the business policy Policy1), Rule2 (corresponding to the business policy Policy2), and Rule3 (corresponding to the business policy Policy3) are instructed. In addition, it is assumed in step 403 that for the specific user User2, the PCC rule Rulel (corresponding to the business policy Policy1), Rule2 (corresponding to the business policy Policy4) and Rule4 (corresponding to the business policy Policy5) are instructed to be installed. Each PCC rule can correspond to a specific business data stream. However, the embodiment of the present invention does not limit the number of PCC rules determined in step 403.

这样，对于不同的用户 Userl和 User2, 可以配置不同的 PCC规则和业务策略，如 Userl配置 Rule3的 Policy3 , User2配置 Rule4的 Policy5; 即使配置相同的 PCC规则，也可以配置相同的业务策略（如 Userl和 User2均配置的 Rulel的 Policyl )或不同的业务策略 (如 Userl配置的 Rule2的 Policy2 以及 User2配置的 Rule2的 Policy4 )。按照现有技术的方法，实现上述配置至少需要 5条 PCC规则，但本发明实施例只需要 4条 PCC规则，这样可以灵活地执行 PCC控制，并且可以减少 PCC规则的总数。 In this way, different PCC rules and service policies can be configured for different users, such as Userl and User2. For example, User1 configures Policy3 of Rule3 and User2 configures Policy5 of Rule4. Even if the same PCC rules are configured, you can configure the same service policy (such as Userl). Both Ruel's Policyl and User2 are configured with different business policies (such as Policy2 of Rule1 configured by Userl and Policy4 of Rule2 configured by User2). According to the prior art method, at least five PCC rules are required to implement the above configuration, but the embodiment of the present invention requires only four PCC rules, so that PCC control can be flexibly performed, and the total number of PCC rules can be reduced.

404, PCEF分别接收到特定用户 Userl和 User2的上下行用户报文。 Userl和 User2的用户文可以属于访问同一业务的业务数据流，也可以属于不同业务的业务数据流。这里假设 Userl和 User2的用户报文属于同一业务的业务数据流。 404. The PCEF receives the uplink and downlink user messages of the specific users User1 and User2, respectively. User1 and User2 can belong to the service data flow of the same service or the service data flow of different services. It is assumed here that the user packets of User1 and User2 belong to the service data stream of the same service.

405, PCEF检测业务数据流，按照步骤 403确定的 PCC规则的优先级匹配 PCC规则。 405. The PCEF detects the service data flow, and the PCC rule according to the priority determined by the step 403 matches the PCC rule.

406,当匹配到预定义 PCC规则时， PCEF根据步骤 503中的 Policy-Name 指示的业务策略名称，确定该匹配的预定义 PCC规则对应的业务策略（即图 1中的 "第一业务策略" 的例子），从而获取对应的计费和 /或控制策略。 406: When matching the predefined PCC rule, the PCEF determines, according to the service policy name indicated by the Policy-Name in step 503, the service policy corresponding to the matched predefined PCC rule (ie, the “first service policy” in FIG. 1). An example) to obtain a corresponding billing and/or control strategy.

假设 Userl和 User2的业务数据流均匹配 Rule2,则 Userl的业务策略应使用 Policy2, 而 User2的业务策略应使用 Policy4。 Assuming that the service data flows of Userl and User2 both match Rule2, Userl's business policy should use Policy2, and User2's business policy should use Policy4.

407, PCEF根据步骤 406得到的业务策略，分别控制特定用户的业务数据流。 407. The PCEF controls the service data flow of the specific user according to the service policy obtained in step 406.

按照本发明实施例，即使对于相同业务的业务数据流，仅使用少量 PCC 规则，就可以配置不同用户使用不同的业务策略，能够支持运营商灵活部署多样化的业务，而不需要多个 PCC规则，降低了配置和维护的复杂度。而且，本发明实施例避免匹配多个 PCC规则带来的性能消耗，而不影响*** 性能。 According to the embodiment of the present invention, even if a small number of PCC rules are used for the service data flow of the same service, different users can be configured to use different service policies, which can support the operator to flexibly deploy diverse services without multiple PCC rules. , reducing the complexity of configuration and maintenance. Moreover, embodiments of the present invention avoid matching performance consumption caused by multiple PCC rules without affecting system performance.

图 5是本发明另一实施例的策略和计费控制过程的流程图。图 5的实施例中，扩展 Diameter CCA消息新增一个独立于 Charging-Rule-Install的 AVP, 携带策略指定信息。另外，类似于图 5 的方式，本发明实施例也可以扩展 Diameter RAR消息新增一个独立于 Charging-Rule-Install的 AVP, 携带策略指定信息，为避免重复，这里不再详细描述。 FIG. 5 is a flowchart of a policy and charging control process according to another embodiment of the present invention. In the embodiment of FIG. 5, the extended Diameter CCA message adds an AVP independent of Charging-Rule-Install, carrying policy designation information. In addition, similar to the manner of FIG. 5, the embodiment of the present invention may also extend a Diameter RAR message to add an AVP that is independent of Charging-Rule-Install, and carry policy designation information. To avoid repetition, details are not described herein.

501，进行业务规划， PCEF和 PCRF配置预定义 PCC规则。例如，建立如图 2所示的预定义 PCC规则。 501, Perform business planning, PCEF and PCRF to configure predefined PCC rules. For example, create a predefined PCC rule as shown in Figure 2.

502, 在 IP-CAN会话建立或修改过程中， PCEF向 PCRF发送针对特定用户 Userl的请求，请求相应的 PCC策略。该请求可以由 Diameter CCR消息携带。本发明实施例对用户的数目不作限制。 502. During the IP-CAN session establishment or modification process, the PCEF sends a request for the specific user User1 to the PCRF to request a corresponding PCC policy. This request can be carried by the Diameter CCR message. The embodiment of the present invention does not limit the number of users.

503， PCRF向 PCEF发送 Diameter CCA消息。 503. The PCRF sends a Diameter CCA message to the PCEF.

该 Diameter CCA 消息中携带与现有技术相同的 Charging-Rule-Install AVP, 指示安装 PCC 规则。另外，该 Diameter CCA 消息中携带新增的 Policy-Name AVP, 携带策略指定信息。可选地，如果 Diameter CCA消息中没有携带新增的 Policy-Name AVP , 则预定义 PCC规则按照缺省的计费和 /控制策略名进行处理。 The Diameter CCA message carries the same Charging-Rule-Install AVP as the prior art, indicating that the PCC rules are installed. In addition, the Diameter CCA message carries a new Policy-Name AVP, which carries policy designation information. Optionally, if the newly-added Policy-Name AVP is not carried in the Diameter CCA message, the predefined PCC rule is processed according to the default charging and/or control policy name.

以下是扩展 Diameter CCA 消息新增 AVP 的一个具体实现，新增 Policy-Name AVP指示该用户所支持的所有计费和 /或者控制策略名称。具体实现中， AVP的名称、数据类型都可以具体定义，只要表示相同含义即可，本发明实施例对此不作限制。 The following is a specific implementation of adding an AVP to the extended Diameter CCA message. The new Policy-Name AVP indicates all the accounting and/or control policy names supported by the user. In a specific implementation, the name and the data type of the AVP can be specifically defined, and the embodiment of the present invention is not limited thereto.

< CC-Answer>：: = < Diameter Header: 272, PXY > < CC-Answer>:: = < Diameter Header: 272, PXY >

<Session-Id > <Session-Id >

{ Auth- Application-Id } { Auth- Application-Id }

[Charging-Rule-Install ] [Charging-Rule-Install ]

*[ Policy-Name] *[ Policy-Name]

*[ AVP ] *[ AVP ]

这样， PCEF确定了特定用户适用的 PCC规则。假设 Diameter CCA消息中的 Policy-Name为多个，分别是 Policyl、 Policy2和 Policy7。 Thus, the PCEF determines the PCC rules that are applicable to a particular user. Assume that there are multiple Policy-Names in the Diameter CCA message, namely Policyl, Policy2, and Policy7.

假设在步驟 503中确定对于特定用户 Userl ,指示安装 PCC规则 Rulel。每个 PCC规则可以对应特定的业务数据流。本发明实施例对步骤 503确定的 PCC规则的数目不作限制。 It is assumed that it is determined in step 503 that the PCC rule Rulel is installed for the specific user User1. Each PCC rule can correspond to a particular business data stream. The embodiment of the present invention does not limit the number of PCC rules determined in step 503.

如图 2所示，假设 Rulel中包括 Policyl和 Policy2, 但不包括 Policy7, 因此 PCEF会匹配得到两个业务策略 Policyl和 Policy2。在此情况下， PCEF 可选择优先级高的业务策略（假设为 Policyl )作为 Userl在 Rulel下的业务策略。 As shown in Figure 2, it is assumed that Rulel includes Policyl and Policy2, but does not include Policy7. Therefore, PCEF will match two business policies Policyl and Policy2. In this case, PCEF can choose a high priority business policy (assumed to be Policyl) as Userl's business policy under Rulel.

504, PCEF接收到特定用户 Userl的上下行用户报文。 504. The PCEF receives the uplink and downlink user message of the specific user User1.

505, PCEF检测业务数据流，按照步骤 503确定的 PCC规则的优先级匹配 PCC规则。 505. The PCEF detects the service data flow, and the PCC rule according to the priority determined by the step 503 matches the PCC rule.

506, 当匹配到预定义 PCC规则 Rulel时， PCEF根据步骤 503中的确定的业务策略 Policyl (即图 1 中的 "第一业务策略" 的例子），获取对应的计费和 /或控制策略。 506. When matching the predefined PCC rule Rule1, the PCEF obtains the corresponding charging and/or control policy according to the determined service policy Policy1 in step 503 (ie, the example of the "first service policy" in FIG. 1).

507, PCEF根据步骤 506得到的业务策略，控制特定用户的业务数据流。按照本发明实施例，即使对于相同业务的业务数据流，仅使用少量 PCC 规则，就可以配置不同用户使用不同的业务策略，能够支持运营商灵活部署多样化的业务，而不需要多个 PCC规则，降低了配置和维护的复杂度。而且，本发明实施例避免匹配多个 PCC规则带来的性能消耗，而不影响*** 性能。 507. The PCEF controls the service data flow of the specific user according to the service policy obtained in step 506. According to an embodiment of the present invention, even for a service data flow of the same service, only a small amount of PCC is used. The rules can be used to configure different users to use different service policies. This allows operators to flexibly deploy diverse services without requiring multiple PCC rules, reducing the complexity of configuration and maintenance. Moreover, embodiments of the present invention avoid matching performance consumption caused by multiple PCC rules without affecting system performance.

另夕卜，图 4和图 5的实施例中， [Policy-Name]也可以用 [Policy-List]代替。 In addition, in the embodiments of Figs. 4 and 5, [Policy-Name] can also be replaced with [Policy-List].

[Policy-List]以集合的形式指示一个或多个业务策略名称。 PCEF 将该 Policy-List (上述第一集合的一个变型）和本地的预定义 PCC规则下的业务策略列表（上述第二集合）进行比较，以得到匹配的业务策略。这样的修改也落入本发明实施例的范围内。 [Policy-List] indicates one or more business policy names in the form of a collection. The PCEF compares the Policy-List (a variant of the first set above) with the list of service policies (the second set above) under the local predefined PCC rules to obtain a matching business policy. Such modifications are also within the scope of embodiments of the invention.
