Technical field

本发明实施例涉及通信技术领域，特别涉及一种群组策略与计费规则处理方法、装置以及通信***。背景技术 The embodiments of the present invention relate to the field of communications technologies, and in particular, to a group policy and charging rule processing method, apparatus, and communication system. Background technique

现有技术的策略与计费控制（Pol icy Charg ing Cont rol，以下简称： PCC ) 机制制定了用户在开展业务时，需要为所有用户的每一业务服务数据流建立独立的策略控制机制，在 IP CAN会话建立流程中包括如下的步骤，首先网关在接收到用户设备发起的 IP-CAN会话建立请求消息（分配一个网络 PDN网络可见的 IP地址）后，向 PCRF发送包括 UE标识、 IP地址和 APN信息的 IP CAN 会话建立消息，通知 PCRF IP CAN会话建立， PCRF如果需要用户签约相关信息，则向 SPR发送用户签约信息请求消息（Prof i le Reques t ) 消息， SPR返回用户签约信息响应消息，包括用户当前签约的业务、计费模式等信息； PCRF 生成新的计费规则，并通过 IP CAN会话建立确认消息将 PCC规则返回给网关 ( GW ) ,网关安装规则，并根据规则打开或者关闭对应的业务数据流，执行相应的 QoS及计费规则，随后 GW向 UE发送 IP CAN会话建立响应消息。 The prior art Policy and Charging Control (PCC) mechanism establishes that when a user conducts a service, it needs to establish an independent policy control mechanism for each service data flow of all users. The IP CAN session establishment process includes the following steps. First, after receiving the IP-CAN session establishment request message initiated by the user equipment (assigning an IP address visible to the network PDN network), the gateway sends the UEF, including the UE identifier, the IP address, and the PCRF. The IP CAN session establishment message of the APN information notifies the PCRF that the IP CAN session is established. If the user needs to sign the related information, the PCRF sends a user subscription information request message (Prof i le Reques t ) message to the SPR, and the SPR returns the user subscription information response message. The information including the current subscription service and charging mode of the user is generated; the PCRF generates a new charging rule, and returns the PCC rule to the gateway (GW) through the IP CAN session establishment confirmation message, and the gateway installs the rule, and opens or closes the corresponding according to the rule. Business data flow, implementing the corresponding QoS and charging rules, The GW then sends an IP CAN Session Setup Response message to the UE.

发明人在实现本发明的过程中发现：对于机器类型通信（Machine Type Commun i ca t i on,以下筒称： MTC )应用，即一个或多个网元或设备之间不需要认为参与的情况下进行的网络通信，也可称为机器对机器（Machine to Machine , 以下筒称： M2M )应用，例如在交通控制和管理、工厂控制和远程抄表的应用，运营商根据上述的 M2M应用的特点将 MTC设备组成群组。例如对于远程抄表的应用，运营商会将某个区域的电表设备组成一个群组，而上述群组中的 MTC设备都具有相同的 M2M设备属性信息，如低移动、时延不敏感等特点，当上述 MTC设备接入网络后，如果按照现在的 PCC的处理机制，网络侧对每个 MTC设备发起的每一个业务建立都需要执行并下发相应的 PCC 规则，但是由于 MTC设备数量众多，所以如果按照现有的 PCC的处理机制，必将会对网络的性能造成大量的开销。另外，某些 M2M设备应用简单，且对于属于同一个群组的 MTC设备来讲，具有相同的 M2M设备属性信息，即其业务类型是一致的，如上述的远程抄表业务，对于上述的群组的 MTC设备可以共享相同的 PCC控制策略，如果按照现有的 PCC的处理机制，存在策略控制效率低下、策略维护复杂的缺点。发明内容 The inventor found in the process of implementing the present invention: For the Machine Type Communication (MTC) application, that is, one or more network elements or devices do not need to be considered to participate in the case Network communication, also known as Machine to Machine (M2M) applications, such as traffic control and management, factory control and remote meter reading applications, operators based on the characteristics of the above M2M applications Group MTC devices into groups. For example, for remote meter reading applications, the operator will group the meter devices in a certain area into a group. The MTC devices in the group all have the same M2M device attribute information, such as low mobility and delay insensitivity. After the MTC device accesses the network, if the current PCC processing mechanism is followed, the network side pairs each. Each service establishment initiated by the MTC device needs to execute and deliver the corresponding PCC rules. However, due to the large number of MTC devices, if the existing PCC processing mechanism is used, a large amount of overhead will be incurred on the performance of the network. In addition, some M2M devices are simple to apply, and have the same M2M device attribute information for the MTC devices belonging to the same group, that is, their service types are consistent, such as the above-mentioned remote meter reading service, for the above group The group of MTC devices can share the same PCC control strategy. If the existing PCC processing mechanism is used, there are disadvantages such as inefficient policy control and complicated policy maintenance. Summary of the invention

用户设备的群组标识对于用户组或者群组用户来说，是用户组标识（也可以描述为用户组用户标识）或者群组标识（也可以描述为群组用户标识），或者其他指示用户设备所属群组或者用户组的标识，例如，通过 APN ( Acces s Point Name )标识用户设备所属群组或者用户组，则 APN就是用户设备所属群组或者用户组的标识，本实施例中对群组标识不做限制。所述群组或者用户组可以是用户设备组或者 M2M行业用户（MTC User )或者 M2M应用签约用户（MTC Subscr iber )或者其他由多个设备组成的群组，本实施例中不作限制。 The group identifier of the user equipment is a user group identifier (which may also be described as a user group user identifier) or a group identifier (which may also be described as a group user identifier) for the user group or the group user. Or the identifier of the group or the user group to which the user equipment belongs, for example, the group or the user group to which the user equipment belongs is identified by the APN (Aces s Point Name), and the APN is the identifier of the group or user group to which the user equipment belongs. In the example, there is no restriction on the group identifier. The group or the user group may be a user equipment group or an M2M industry user (MTC User) or an M2M application subscription user (MTC Subscr iber) or other group of multiple devices, which is not limited in this embodiment.

其中，设备属性信息为具有相同特性的用户设备所共有的属性信息，是根据不同的行业用户（MTC User )或者 M2M应用签约用户（MTC Subscr iber ) 不同的应用而获得的不同的设备特征信息，也可以称为是设备特征（Machine Fea ture )或者设备类型（Machine Type )或者服务类别（Servi ce Cla s s )。例如对于远程抄表***中的用户设备具有低移动、时延不敏感等特点，则其设备属性信息是低移动、时延不敏感等；本实施例不对设备属性信息所包含的内容和设备属性信息的名称做限制。 The device attribute information is attribute information shared by the user equipments having the same characteristics, and is different device feature information obtained according to different applications of different industry users (MTC User) or M2M application subscription users (MTC Subscr iber).

The PGW, the SGW, or the GGSN sends an IP CAN session establishment indication message to the PCRF, where the message may carry the group identifier of the user equipment or device attribute information of the user equipment. After obtaining the group identifier of the user equipment, the PCRF may carry the group identifier of the user equipment in a configuration information request message (Prof ile Reques t ) sent to the SPR. In addition, the PCRF may also obtain the foregoing group identifier or device attribute information by receiving a configuration information response message (Profed Response) returned by the SPR, that is, the configuration information response message carries the group identifier of the user equipment or Device attribute information. The PCRF formulates a PCC rule or a trigger event according to at least one of a group identifier or device attribute information to which the user equipment belongs or service subscription data of the user equipment.

The application scope is a PCC policy of a group or a user equipment group, so that the service data flow template is not provided in the PCC rule. Or the PCRF formulates a PCC policy whose application scope is a group or a user equipment group according to at least one of a group identifier or a device attribute information of the user equipment, but the PCRF further provides a service data flow template in the PCC rule. When the dynamic PCC rule is applied, the method for the service data flow template generated by the PCRF in the PCC rule includes: a), when the user equipment initiates a P匪 connection establishment process (for example, an At tach process or a PDN connection establishment process), and the PGW is the above user. The device assignment or the PGW requests the DHCP device to allocate an IPv4 address or an IPv6 address to the user equipment. The PGW learns the group identifier of the user equipment, and the PGW allocates an IP address to the user equipment according to the group identifier of the user equipment or allocates a group or user group granularity to the user equipment according to the DHCP request, and the specific method includes: The PGW allocates an IPv6 address prefix of a group or a user group granularity according to the group identity of the user equipment or the DHCP request to the user equipment of the group or the user group to which the user equipment belongs (a complete IPv6 address is The two components are the IPv6 address prefix and the IPv6 interface identifier. The IPv6 address prefix is a group or user group granularity, that is, when the second user equipment that belongs to the same group as the user equipment (the first user equipment) initiates a PDN connection establishment procedure for the same APN, the PGW is the second. The user equipment allocates an IPv6 address prefix to be the same as the IPv6 address prefix allocated by the PGW for the user equipment (the first user equipment) (ie, the PGW allocates the IPv6 address prefix allocated for the first user equipment as the PGW to the second user equipment. IPv6 address prefix). Or the PGW allocates a public IPv4 address to the user equipment in the group or the user group to which the user equipment belongs according to the group identifier of the user equipment.
