FIG. 9 is a schematic structural diagram of another service type-based gateway control plane entity and a gateway user plane entity according to Embodiment 2 of the present invention. The function of the gateway before and after the cancellation of the IP service function is as shown in Figure 9.

The cancellation identifier may be represented as DEL, and the packet processing action to be canceled may be a URL filtering message processing action, and the message processing action to be canceled may be represented as a URL Filter. Alternatively, the action cancellation indication information of the one action set may further include: indication information and sequence indication information of each message processing action after the message processing action is canceled. The sequence indication information is used to indicate the execution order of the message processing actions of the action set after the service function is cancelled. For example, the order indication information may be ReceivePacket->Decapsulate->Shaping->Charge.

若业务功能类型为IP业务功能增加，如增加流量订购功能，该变化后的网关功能可为增加流量订购功能后的网关功能。图10为本发明实施例二提供的又一种基于业务功能类型的网关控制面实体与网关用户面实体的结构示意图。执行IP业务功能增加前和增加后的网关功能如图10所示，执行IP业务功能增加后，动作集的报文处理动作可包括增加IP业务功能对应的报文处理动作后的各报文处理动作，如ReceivePacket的报文处理动作、Decapsulate的报文处理动作、Shaping的报文处理动作、Charge的报文处理动作、ICAP的报文处理动作。由于业务类型为IP业务功能增加，则在该控制信息中，动作集指示信息包括动作集的动作增加指示信息。该动作***指示信息可包括：增加标识、需增加的报文处理动作和该需增加的报文处理动作在增加前动作集中多个报文处理动作中的位置，其中，该增加标识可表示为Insert，该需增加的报文处理动作可表示为ICAP->AC，该需增加的报文处理动作的位置可表示为charge后。可替代地，动作增加指示信息还可包括：增加报文处理动作后的各报文处理动作的指示信息、顺序指示信息。该顺序指示信息用于指示业务功能增加后该动作集的报文处理动作的执行顺序。例如，该顺序指示信息可以为ReceivePacket->Decapsulate->Shaping->Charge->ICAP->AC。If the service function type is increased for the IP service function, such as the traffic subscription function, the changed gateway function may be a gateway function after the traffic subscription function is added. FIG. 10 is a schematic structural diagram of another gateway control plane entity and a gateway user plane entity based on a service function type according to Embodiment 2 of the present invention. The function of the gateway before and after the IP service function is added is as shown in Figure 10. After the IP service function is added, the packet processing action of the action set may include adding the packet processing after the packet processing action corresponding to the IP service function. Actions, such as ReceivePacket's message processing action, Decapsulate's message processing action, Shaping's message processing action, Charge's message processing action, and ICAP message processing action. Since the service type is an IP service function, in the control information, the action set indication information includes action increase indication information of the action set. The action insertion indication information may include: adding an identifier, a message processing action to be added, and a position of the message processing action to be added in a plurality of message processing actions in the pre-action set, wherein the added identifier may be represented as Insert, the message processing action to be added can be expressed as ICAP->AC, and the position of the message processing action to be added can be expressed as charge. Alternatively, the action increase indication information may further include: indication information and sequence indication information of each message processing action after the message processing action is increased. The sequence indication information is used to indicate the execution order of the message processing actions of the action set after the service function is added. For example, the sequence indication information may be ReceivePacket->Decapsulate->Shaping->Charge->ICAP->AC.

可选的，该网关用户面实体根据该动作集对应的报文处理动作，和该报文处理动作的动作参数对该报文进行处理。Optionally, the gateway user plane entity processes the packet according to the packet processing action corresponding to the action set and the action parameter of the packet processing action.

本发明实施例二提供的报文处理方法中，由于网关控制面实体发送的控制信息中包括动作集指示信息，因而网关用户面实体可根据该动作集指示信息确定动作集，实现该动作集对应的多个网关功能，实现网关功能的融合，提高网关用户面实体的网关功能的兼容性和扩展性，且大大超越了传统网关的网关功能的兼容性和扩展性。 In the packet processing method provided by the second embodiment of the present invention, the control information sent by the gateway control plane entity includes the action set indication information, so the gateway user plane entity may determine the action set according to the action set indication information, and implement the action set correspondingly. Multiple gateway functions enable the convergence of gateway functions, improve the compatibility and scalability of the gateway function of the gateway user plane entity, and greatly exceed the compatibility and scalability of the gateway function of the traditional gateway.

同时，由于该动作集的指示信息还包括该顺序指示信息，因而可使得该网关用户面实体根据该动作集对应的报文处理动作的执行顺序，对该报文进行多种不同的动作处理，可在简化EPS网络架构的基础上，保证网关用户面设备对该报文处理的准确度。At the same time, the indication information of the action set further includes the sequence indication information, so that the gateway user plane entity can perform a plurality of different action processing on the message according to the execution order of the message processing action corresponding to the action set. On the basis of simplifying the EPS network architecture, the accuracy of processing the packet by the gateway user plane device can be ensured.

本发明实施例三还提供一种报文处理方法。可选的，该控制信息还可包括：对象集指示信息；该对象集包括：至少一个对象(Object)；其中，每个对象与报文处理动作对应。该对象集指示信息，可包括对象集中每个对象的标识。该网关用户面实体可根据该对象集中每个对象对应的报文处理动作，对该报文进行处理。每个对象与所述报文处理动作中的至少一个报文处理动作相关联。 Embodiment 3 of the present invention further provides a packet processing method. Optionally, the control information may further include: object set indication information; the object set includes: at least one object (Object); wherein each object corresponds to a message processing action. The object set indication information may include an identification of each object in the object set. The gateway user plane entity can process the packet according to the packet processing action corresponding to each object in the object set. Each object is associated with at least one message processing action in the message processing action.

每个对象可以对应至少一个报文处理动作，每个对象对应的至少一个报文处理还具有对应的执行顺序，因而该对象集指示信息可包括：顺序指示信息。该网关用户面实体可按照每个对象内报文处理动作的执行顺序，对该报文依次进行处理。Each object may correspond to at least one message processing action, and at least one message processing corresponding to each object further has a corresponding execution order, and thus the object set indication information may include: sequence indication information. The gateway user plane entity may process the message in sequence according to the execution order of the message processing actions in each object.

该对象集包括：至少一个对象，根据不同的维度，每个对象对应一个业务功能对象，或者每个对象对应一个报文操作对象。The object set includes: at least one object, each object corresponding to one business function object according to different dimensions, or each object corresponding to one message operation object.

当每个对象对应一个业务功能对象时，该业务功能对象包括报文处理动作；该控制信息还包括：对象顺序的指示信息；该对象顺序为该至少一个对象对应的报文处理顺序。When each object corresponds to a service function object, the service function object includes a message processing action; the control information further includes: indication information of the object sequence; the object sequence is a message processing sequence corresponding to the at least one object.

该网关用户面设备可根据该对象顺序的指示信息确定该至少一个对象对应的报文处理顺序。The gateway user plane device may determine, according to the indication information of the object sequence, a message processing sequence corresponding to the at least one object.

该网关用户面实体可根据对应的报文处理顺序，先采用对象集中的第一个对象对应的各报文处理动作依次对该报文进行处理，然后采用该对象集中下一对象的各报文处理动作对该报文进行处理，直至根据该对象集中的所有对象的报文处理动作对该报文均已处理完毕，则该网关用户面实体完成对该报文的处理。 The user plane entity of the gateway may process the packet in turn according to the processing sequence of the corresponding packet, and then adopt the packet processing action corresponding to the first object in the object set, and then adopt the packet of the next object in the object set. The processing action processes the packet until the packet processing has been processed according to the packet processing action of all objects in the object set, and the gateway user plane entity completes processing the packet.

例如，业务功能对象包括：隧道(Tunnel)对象、计费(CHarGe，简称CHG)对象、服务质量(Quality of Service，简称QoS)对象或统一资源定位符(Uniform Resource Locator，简称URL)过滤对象等业务功能对象中的任一项。For example, the service function object includes: a tunnel object, a charging (CHarGe, abbreviated as CHG) object, a quality of service (QoS) object, or a Uniform Resource Locator (URL) filtering object. Any of the business function objects.

举例来说，若一个对象集包括四个业务功能对象，如Tunnel对象、QoS对象、CHG对象和URL过滤对象。该对象集指示信息包括每个对象的名称，如Tunnel、QoS、CHG和URL。该对象集指示信息还包括：对象顺序的指示信息，如Tunnel->QoS->CHG->URL。图11为本发明实施例三提供的一种网关控制面实体与网关用户面实体的结构示意图。该网关用户面实体可根据该对象集的指示信息确定该对象集的每个对象，及该对象集中各对象对应的报文处理顺序。该网关用户面实体还根据该对象集中各对象，及预设的对象与报文处理动作的对应关系，得到如图11所示的该网关用户面实体的对象集。图11中，该Tunnel对象可包括：Encapsulate的报文处理动作、Decapsulate的报文处理动作和标识(Remark)的报文处理动作；该CHG对象可包括：Charge的报文处理动作；该QoS对象可包括：Car的报文处理动作和Shaping的报文处理动作；该URL过滤对象可包括因特网内容适配协议(Internet Content Adaptation Protocol，简称ICAP)的报文处理动作。For example, if an object set includes four business function objects, such as a Tunnel object, a QoS object, a CHG object, and a URL filtering object. The object set indication information includes the name of each object, such as Tunnel, QoS, CHG, and URL. The object set indication information further includes: indication information of the object order, such as Tunnel->QoS->CHG->URL. FIG. 11 is a schematic structural diagram of a gateway control plane entity and a gateway user plane entity according to Embodiment 3 of the present invention. The gateway user plane entity may determine, according to the indication information of the object set, each object of the object set, and a message processing order corresponding to each object in the object set. The gateway user plane entity further obtains an object set of the gateway user plane entity as shown in FIG. 11 according to each object in the object set and a corresponding relationship between the preset object and the packet processing action. In FIG. 11 , the tunnel object may include: a packet processing action of the Encapsulate, a packet processing action of the Decapsulate, and a message processing action of the identifier (Remark); the CHG object may include: a packet processing action of the tag; the QoS object The message processing action of the Car and the packet processing action of the Shaping may be included; the URL filtering object may include a message processing action of the Internet Content Adaptation Protocol (ICAP).

网关用户面实体可以根据该对象集各对象对应的报文操作顺序，依次采用该Tunnel对象的各报文处理动作、该CHG对象的报文处理动作；该QoS对象的报文处理动作、该URL过滤对象的报文处理动作对该报文进行处理。The gateway user plane entity can sequentially adopt the packet processing action of the tunnel object and the packet processing action of the CHG object according to the packet operation sequence corresponding to each object of the object set; the message processing action of the QoS object, the URL The packet processing action of the filtering object processes the packet.

可替代的，若对象为报文操作对象，该报文操作对象可包括至少一个对应多个实例的报文操作对象；每个实例与该报文处理动作中的至少一个报文处理动作相关联；该控制信息还包括：对象实例顺序的指示信息；该对象实例顺序为该报文操作对象的实例对应的报文处理顺序。Alternatively, if the object is a message operation object, the message operation object may include at least one message operation object corresponding to multiple instances; each instance is associated with at least one message processing action in the message processing action The control information further includes: indication information of the order of the object instance; the order of the object instance is a processing sequence of the message corresponding to the instance of the operation object of the message.

具体地，若该报文操作对象中包括至少一个可对应多个实例的报文操作读对象，则该网关用户面实体可以是对象实例对应的报文处理顺序，依次根据该对象集中的各对象实例对该报文进行处理。该网关用户面实体可以是根据该对象实例对应的报文处理顺序，先采用对象集中的第一个对象实例对应的各报文处理动作依次对该报文进行处理，然后采用该对象集中下一对象实例的各报文处理动作对该报文进行处理，直至根据该对象集中的所有的对象实例的报文处理动作对该报文均已处理完毕，则该网关用户面实体完成对该报文的处理。Specifically, if the packet operation object includes at least one packet operation read object that can correspond to multiple instances, the gateway user plane entity may be a packet processing sequence corresponding to the object instance, and sequentially according to each object in the object set. The instance processes the message. The user plane entity of the gateway may be processed according to the processing sequence of the packet corresponding to the object instance, and the packet processing action of each object instance corresponding to the first object instance in the object set is processed in turn, and then the next object is used in the object set. Each message processing action of the object instance processes the message until all objects in the object set are After the packet processing action of the instance has been processed, the gateway user plane entity completes processing the packet.

在如上所述的方法中该每个对象对应一个业务功能对象，该又一种方法中该每个对象对应一个对象实例，该一个对象实例为一个报文操作对象的一个实例。因此，由于对象不同，不同对象关联的报文处理动作也不同。举例来说，若一个对象对应一个业务功能对象，如Tunnel对象，则该一个对象关联的报文处理动作可包括：Encapsulate的报文处理动作、Decapsulate的报文处理动作和标识(Remark)的报文处理动作。若该一个对象对应一个报文操作对象的一个实例，如Bearer对象第一实例，则该一个对象关联的报文处理动作可包括：Remark的报文处理动作。In the method as described above, each object corresponds to a business function object, and in the further method, each object corresponds to an object instance, and the object instance is an instance of a message operation object. Therefore, due to different objects, the message processing actions associated with different objects are also different. For example, if an object corresponds to a service function object, such as a tunnel object, the packet processing action associated with the object may include: Encapsulate packet processing action, Decapsulate packet processing action, and Remark report. Text processing action. If the object corresponds to an instance of a message operation object, such as the first instance of the Bearer object, the message processing action associated with the object may include: Remark message processing action.

因此，如上的方法与该又一种方案的区别在于，各对象不同，各对象相关联的报文处理动作不同，因此，网关用户面实体根据该不同对象相关联的报文处理动作对该报文进行处理，所实现的网关功能不同。Therefore, the difference between the above method and the other solution is that each object is different, and the packet processing actions associated with each object are different. Therefore, the gateway user plane entity processes the message according to the packet processing action associated with the different object. The text is processed, and the implemented gateway functions are different.

需要说明的是，同一个报文操作对象的不同实例相关联的报文处理动作。举例来说，若该一个报文操作对象为Bearer对象，该Bearer对象第一实例关联的报文处理动作可包括：Remark的报文处理动作，该Bearer对象第二实例关联的报文处理动作可包括：Charge的报文处理动作。It should be noted that the message processing actions associated with different instances of the same message operation object. For example, if the message operation object is a Bearer object, the message processing action associated with the first instance of the Bearer object may include: a Remark message processing action, and the message processing action associated with the second instance of the Bearer object may be Including: Charge's message processing action.

举例来说，若一个对象集包括：三个对象，如Link对象、Bearer对象、Flow对象。其中，Link对象具有一个实例，Bearer对象具有两个实例，即Bearer对象第一实例和Bearer对象第二实例，Flow对象具有一个实例。该对象集的指示信息包括该每个对象的实例相关联的报文处理动作的指示信息。该每个对象的实例相关联的报文处理动作的指示信息可包括：该每个对象的名称和该每个对象的实例相关联的报文处理动作的名称，如Link.Decapsulate、Bearer0.Remark、Bearer1.Charge、Flow.Car和Flow.Shaping。该对象集的指示信息还包括：对象实例顺序的指示信息，如Link.Decapsulate->Bearer0.Remark->Flow.Car->Flow.Shaping->Bearer1.Charge。图12为本发明实施例三提供的另一种网关控制面实体与网关用户面实体的结构示意图。该网关用户面实体可根据该对象集的指示信息确定该对象集的每个对象的实例相关联的报文处理动作，及该对象集中各对象的实例对应的报文处理顺序，得到如图12所示的该网关用户面实体的对象集。图12中，该Link对象实例包括：Decapsulate的报文处理动作；Bearer对象第一实例包括Remark的报文处理动作；Flow对象实例可包括Car的报文处理动作、Shaping的报文处理动作；Bearer对象第二实例可包括：Charge的报文处理动作。For example, if an object set includes: three objects, such as a Link object, a Bearer object, and a Flow object. The Link object has one instance, and the Bearer object has two instances, that is, the first instance of the Bearer object and the second instance of the Bearer object, and the Flow object has one instance. The indication information of the object set includes indication information of a message processing action associated with the instance of each object. The indication information of the message processing action associated with the instance of each object may include: a name of the object and a name of a message processing action associated with the instance of each object, such as Link.Decapsulate, Bearer0.Remark , Bearer1.Charge, Flow.Car, and Flow.Shaping. The indication information of the object set further includes: indication information of the order of the object instance, such as Link.Decapsulate->Bearer0.Remark->Flow.Car->Flow.Shaping->Bearer1.Charge. FIG. 12 is a schematic structural diagram of another gateway control plane entity and a gateway user plane entity according to Embodiment 3 of the present invention. The gateway user plane entity may determine the object set according to the indication information of the object set The message processing action associated with the instance of each object, and the message processing order corresponding to the instance of each object in the object set, results in a set of objects of the gateway user plane entity as shown in FIG. In Figure 12, the Link object instance includes: a packet processing action of the Decapsulate; the first instance of the Bearer object includes a Remark packet processing action; and the Flow object instance may include a Car packet processing action and a Shaping packet processing action; Bearer The second instance of the object may include: a message processing action of the Charge.

网关用户面实体可以根据该对象集各对象实例对应的报文操作顺序，依次采用该Link对象的实例相关联的报文处理动作、该Bearer对象第一实例相关联的报文处理动作；该Flow对象的实例的各报文处理动作、Bearer对象第二实例相关联的报文处理动作对该报文进行处理。The gateway user plane entity may sequentially adopt the packet processing action associated with the instance of the Link object and the packet processing action associated with the first instance of the Bearer object according to the packet operation sequence corresponding to each object instance of the object set; Each message processing action of the instance of the object and the message processing action associated with the second instance of the Bearer object process the message.

本发明实施例三提供的报文处理方法，分别通过对象集中各对象对应的不同对象实例的方案对上述实施例所述的方法进行进一步的说明，可使得该网关用户面实体对报文处理的精度更好，从而更好地实现多种网关功能在该网关用户面实体的融合，使得新业务的部署更灵活更迅速。The method for processing a packet according to the third embodiment of the present invention further describes the method in the foregoing embodiment by using a solution of a different object instance corresponding to each object in the object set, so that the gateway user plane entity can process the packet. The accuracy is better, so that the integration of multiple gateway functions in the gateway user plane entity is better realized, and the deployment of new services is more flexible and faster.

本发明实施例四还提供一种报文处理方法。可选的，该每个对象可对应一个报文操作对象的一个实例；该一个报文操作对象的一个实例包括报文处理动作。图13为本发明实施例四提供的网关控制面实体和网关用户面实体的结构示意图。 Embodiment 4 of the present invention further provides a packet processing method. Optionally, each object may correspond to an instance of a message operation object; an instance of the one message operation object includes a message processing action. FIG. 13 is a schematic structural diagram of a gateway control plane entity and a gateway user plane entity according to Embodiment 4 of the present invention.

如图13所示，对象集包括：Link对象、Bearer对象、Flow对象这三个报文操作对象。其中，每个对象对应一个实例，即该对象集可对应Link对象实例、Bearer对象实例、Flow对象实例。其中，Link对象实例包括：Decapsulate的报文处理动作；Bearer对象实例包括Remark的报文处理动作、Charge的报文处理动作。Flow对象实例可包括Car的报文处理动作、Shaping的报文处理动作。在图13的例子中，由于需要在不同步骤中执行Bearer对象实例中的不同报文处理动作，Bearer对象实例还包括动作匹配(OperationMatch)的报文处理动作。网关用户面实体可通过执行该OperationMatch的报文处理动作，确定该Bearer对象实例中需执行的报文处理动作是Remark的报文处理动作还是Charge的报文处理动作。As shown in FIG. 13, the object set includes three message operation objects: a Link object, a Bearer object, and a Flow object. Each object corresponds to an instance, that is, the object set can correspond to a Link object instance, a Bearer object instance, and a Flow object instance. The Link object instance includes: Decapsulate packet processing action; the Bearer object instance includes Remark packet processing action and Charge message processing action. The Flow object instance may include a message processing action of the Car and a message processing action of the Shaping. In the example of FIG. 13, since the different message processing actions in the Bearer object instance need to be performed in different steps, the Bearer object instance further includes a message matching action of the action matching (OperationMatch). The gateway user plane entity can perform the message processing action of the OperationMatch to determine whether the packet processing action to be performed in the Bearer object instance is a Remark packet processing action or a Charge packet processing action.

图14为本发明实施例四提供的一种报文处理方法的流程图。图14将结合图13进行描述。如图14所示，网关用户面实体根据该对象集中该每个对象对应的报文处理动作，对该报文进行处理，可以包括：FIG. 14 is a flowchart of a packet processing method according to Embodiment 4 of the present invention. Figure 14 will be described in conjunction with Figure 13. As shown in FIG. 14, the gateway user plane entity concentrates each pair according to the object set. The processing of the packet, such as the corresponding packet processing action, may include:

S1401、该网关用户面实体根据该报文中的计数标签(ProIndex)值确定该对象集中的一个对象的实例相关联的报文处理动作。S1401: The gateway user plane entity determines, according to a count label (ProIndex) value in the packet, a packet processing action associated with an instance of an object in the object set.

该计数标签值可以为预设的整数值，则该一个对象为该对象集中的第一个对象。举例来说，该第一个对象可以为图13中的Link对象，该预设整数值可以为整数0。该预设的整数值可以称为初始计数标签值。The count tag value can be a preset integer value, and the one object is the first object in the object set. For example, the first object may be the Link object in FIG. 13, and the preset integer value may be an integer 0. The preset integer value may be referred to as an initial count tag value.

对象集中不同的对象分别对应具有不同的计数标签值。进一步地，同一对象中的不同报文处理动作可对应不同的计数标签值。若该预设的整数值为0，该计数标签值为1，则包含当前要对报文执行的报文处理动作的对象为Bearer对象，当前要对报文执行的报文处理动作可以为Bearer对象实例的该动作匹配的报文处理动作，该网关用户面实体可通过执行该OperationMatch的报文处理动作确定Remark报文处理动作。若该预设的整数值为0，则该计数标签值为2，则包含当前要对报文执行的报文处理动作的对象可以为Flow对象，当前要对报文执行的报文处理动作可以为Flow对象实例的Car报文处理动作和Shaping报文处理动作。Different objects in the object set respectively have different count tag values. Further, different message processing actions in the same object may correspond to different count tag values. If the preset integer value is 0, and the count label value is 1, the object that contains the current packet processing action to be performed on the packet is a Bearer object, and the current packet processing action to be performed on the packet may be Bearer. The message processing action matched by the action of the object instance, the gateway user plane entity may determine the Remark message processing action by executing the message processing action of the OperationMatch. If the preset integer value is 0, the value of the count label is 2, and the object that includes the current packet processing action to be performed on the packet may be a Flow object, and the current packet processing action to be performed on the packet may be The Car packet processing action and the Shaping packet processing action of the Flow object instance.

在本发明实施例四中，该网关用户面实体可以是根据报文中的计数标签，确定对该报文进行处理所需的对象实例相关联的报文处理动作，继而对该报文进行处理。In the fourth embodiment of the present invention, the gateway user plane entity may determine, according to the counting label in the packet, a packet processing action associated with the object instance required for processing the packet, and then process the packet. .

S1402、该网关用户面实体根据该确定的报文处理动作对报文进行处理，得到处理后的报文；该处理后的报文中的计数标签值为更新后的计数标签值；更新后的计数标签值为更新前的计数标签值加一所得到的值。S1402: The gateway user plane entity processes the packet according to the determined packet processing action, and obtains the processed packet; the counted label value in the processed packet is the updated count label value; and the updated The count tag value is a value obtained by adding one value to the count tag value before the update.

以处理前的计数标签值为预设的整数值0，步骤S1401中确定的对象为该对象集中的第一个对象为例进行说明。该网关用户面实体可以根据该第一对象的实例相关联的报文处理动作，即Link对象的实例的DeCap报文处理动作对该报文进行处理，得到处理后的报文，该处理后的报文中的计数标签的值为更新后的计数标签值。该更新后的计数标签值为预设的整数值0加1，即，该更新后计数标签值等于1。The pre-processing count tag value is a preset integer value 0, and the object determined in step S1401 is the first object in the object set as an example. The gateway user plane entity can process the packet according to the packet processing action associated with the instance of the first object, that is, the DeCap packet processing action of the instance of the Link object, and obtain the processed packet, and the processed packet is processed. The value of the count tag in the message is the updated count tag value. The updated count tag value is a preset integer value of 0 plus 1, that is, the updated count tag value is equal to 1.

S1403、该网关用户面实体确定该更新后的计数标签值是否具有对应的对象实例。S1403. The gateway user plane entity determines whether the updated count label value has a corresponding object instance.

S1404、若该更新后的计数标签值具有对应的对象实例，该用户面实体根据该更新后的计数标签值对应的对象实例相关联的报文处理动作对报文进行处理。S1404. If the updated count label value has a corresponding object instance, the user plane entity root The message is processed according to the packet processing action associated with the object instance corresponding to the updated count tag value.

若该更新后的计数标签值为1，则该网关用户面实体可以确定该更新后的计数标签值对应的对象实例相关联的报文处理动作，为Bearer对象实例的该OperationMatch的报文处理动作，通过执行该OperationMatch的报文处理动作可确定Remark报文处理动作，继而根据该Bearer对象实例的Remark报文处理动作对报文进行处理。If the updated counter tag value is 1, the gateway user plane entity may determine a message processing action associated with the object instance corresponding to the updated count tag value, and the message processing action of the OperationMatch of the Bearer object instance. The Remark message processing action can be determined by executing the message processing action of the OperationMatch, and then the message is processed according to the Remark message processing action of the Bearer object instance.

同理，该网关用户面实体可以根据Bearer对象实例的Remark报文处理动作对报文进行处理，处理后报文中计数标签值更新为2。Similarly, the gateway user plane entity can process the packet according to the Remark packet processing action of the Bearer object instance, and the count label value in the packet is updated to 2.

若计数标签值更新为2，则该网关用户面实体可根据更新后的计数标签值2确定对象实例相关联的报文处理动作为Flow对象实例的Car和Shaping报文处理动作，依次根据该Flow对象实例的Car和Shaping报文处理动作对报文进行处理，将计数标签值更新为3。若计数标签值更新为3，则该网关用户面实体可确定对象实例相关联的报文处理动作为Bearer对象实例的该OperationMatch的报文处理动作，通过执行该OperationMatch的报文处理动作确定Charge报文处理动作，并根据该Bearer对象实例的Charge报文处理动作对该报文进行处理，将计数标签值更新为4。若计数标签值更新为4，该网关用户面实体可确定该对象集中不具有该计数标签值4对应的对象实例相关联的报文处理动作，则该网关用户面实体将包括该计数标签值4的报文进行转发，即发送至该网关用户面实体的下游设备。If the value of the counter tag is updated to 2, the gateway user plane entity may determine, according to the updated count tag value 2, that the packet processing action associated with the object instance is a Car and Shaping packet processing action of the Flow object instance, and sequentially according to the flow. The Car and Shaping message processing actions of the object instance process the message and update the count tag value to 3. If the value of the counter tag is updated to 3, the gateway user plane entity may determine that the message processing action associated with the object instance is the message processing action of the OperationMatch of the Bearer object instance, and determine the Charge message by executing the message processing action of the OperationMatch. The message processing action is performed, and the message is processed according to the Charge message processing action of the Bearer object instance, and the count tag value is updated to 4. If the counter tag value is updated to 4, the gateway user plane entity may determine that the object set does not have the packet processing action associated with the object instance corresponding to the count tag value 4, and the gateway user plane entity includes the count tag value 4 The packet is forwarded, that is, sent to the downstream device of the gateway user plane entity.

需要说明的是，该计数标签值的初始值还可以为其他预设的整数值，上述实施例中的预设整数值0仅为举例说明，并不对本发明作限制。若该计数标签值的初始值为其他预设的整数值，具体的实现过程与上述实施例类似，在此不再赘述。It should be noted that the initial value of the counter tag value may also be other preset integer values. The preset integer value 0 in the foregoing embodiment is merely an example and is not intended to limit the present invention. If the initial value of the counter tag value is another preset integer value, the specific implementation process is similar to the foregoing embodiment, and details are not described herein again.

需要说明得是，若该第一对象为该对象集中的第一个对象，且，该第一对象实例的报文处理次数为1，该处理后的报文包括：该第一对象实例的ID。其中，对象实例的报文处理次数可以为该网关用户面实体需根据该对象实例对报文进行处理的次数。It should be noted that, if the first object is the first object in the object set, and the number of times of processing the first object instance is 1, the processed message includes: the ID of the first object instance. . The number of times the packet processing of the object instance is processed may be the number of times the gateway user plane entity needs to process the packet according to the object instance.

若该第一对象为该对象集中的第一个对象，且，该第一对象实例的报文处理次数大于1，该处理后的报文包括：该第一对象实例的ID和计数标签值；该计数标签值可以为预设的整数值。If the first object is the first object in the object set, and the number of packet processing times of the first object instance is greater than 1, the processed message includes: an ID of the first object instance and a count label value; The count tag value can be a preset integer value.

若该第一对象不是该对象集中的第一个对象、该第一对象以及该第一对象之前至少一个对象的实例的报文处理次数为1，该处理后的报文包括：该第一对象实例的ID。If the first object is not the first object in the object set, the first object, and the instance of the at least one object before the first object has a message processing count of 1, the processed message includes: the first object The ID of the instance.

若该第一对象不是该对象集中的第一个对象、该第一对象之前对象的实例的报文处理次数大于1，且，该第一对象实例的报文处理次数为1，该处理后的报文包括：该第一对象实例的ID和计数标签值，该计数标签值为处理前报文中的计数标签值。If the first object is not the first object in the object set, the number of packet processing times of the object before the first object is greater than 1, and the number of times of processing the first object instance is 1, the processed object The message includes: an ID of the first object instance and a count label value, and the count label value is a count label value in the pre-process message.

若该第一对象不是该对象集中的第一个对象、该第一对象之前对象的实例的报文处理次数为1，且，该第一对象实例的报文处理次数大于1，该处理后的报文包括：该第一对象实例的ID和计数标签值；该计数标签值可以为预设的整数值。If the first object is not the first object in the object set, the number of times of processing the object of the object before the first object is 1, and the number of times of processing the first object instance is greater than 1, the process is The subsequent message includes: an ID of the first object instance and a count tag value; the count tag value may be a preset integer value.

若该第一对象不是该对象集中的第一个对象、该第一对象之前对象的实例的报文处理次数大于1，且，该第一对象实例的报文处理次数大于1，该处理后的报文包括：该第一对象实例的ID和计数标签值；该计数标签值可以根据处理前报文中的计数标签更新获得。If the first object is not the first object in the object set, the number of times of processing the object of the object before the first object is greater than 1, and the number of times of processing the first object instance is greater than 1, the processed The message includes: an ID of the first object instance and a count label value; the count label value can be obtained according to the count label update in the pre-process message.

举例来说，若该第一对象为图16所示的对象集中的第一个对象，如Link对象，则该处理后的报文可以为该网关用户面实体通过执行S1501，根据该Link对象实例的DeCap的报文处理动作处理后的报文。若该网关用户面实体通过执行S1502确定该第一对象为该对象集中的第一个对象，该Link对象实例的报文处理次数为1，则该网关用户实体可通过执行S1501获得处理后的报文包括：第一对象实例的ID，即该Link对象实例的ID。For example, if the first object is the first object in the object set shown in FIG. 16, such as a Link object, the processed message may be S1501 for the gateway user plane entity, according to the Link object instance. The message of DeCap's message processing action is processed. If the gateway user plane entity determines that the first object is the first object in the object set by executing S1502, and the number of packet processing times of the Link object instance is 1, the gateway user entity may obtain the processed report by executing S1501. The text includes: the ID of the first object instance, that is, the ID of the Link object instance.

该网关用户面实体可通过执行S1502，根据该Link对象实例的ID确定该Link对象的下一对象，即Bearer对象，为该第二对象，并依次通过执行S1503、S1501确定该第二对象的实例相关联的报文处理动作为该Bearer对象实例相关联的报文处理动作，即OperationMatch的报文处理动作，并根据该OperationMatch的报文处理动作对报文进行动作匹配，确定Remark报文处理动作，继而根据Remark报文处理动作对报文进行处理，得到处理后的报文。若该Bearer对象不是该对象集中的第一个对象，该Bearer对象实例的报文处理次数大于1，同时，由于该Link对象的实例的报文处理次数为1，则该网关用户面实体可获得处理后的报文可包括：该Bearer对象实例的ID和计数标签值；该计数标签值可为1。需要说明的是，其中，网关用户面实体根据Bearer对象中的OperationMatch的报文处理动作对报文进行动作匹配，可以是根据该报文和预设的报文处理动作快进行匹配中，从而确定需对报文进行处理的报文处理动作。The gateway user plane entity may determine, according to the ID of the Link object instance, the next object of the Link object, that is, the Bearer object, as the second object, and sequentially determine an instance of the second object by executing S1503, S1501. The associated packet processing action is a packet processing action associated with the Bearer object instance, that is, a message processing action of the OperationMatch, and the action is matched according to the message processing action of the OperationMatch, and the Remark message processing action is determined. Then, according to the Remark message processing action, the message is processed to obtain the processed message. If the Bearer object is not the first object in the object set, the number of packets processed by the Bearer object instance is greater than 1, and the number of packets processed by the instance of the Link object is 1, the gateway user plane entity is available. The processed message may include: an ID of the Bearer object instance and a count tag value; the count tag value may be 1. It should be noted that the gateway user plane entity performs an action matching on the packet according to the message processing action of the OperationMatch in the Bearer object, and may perform matching according to the packet and the preset packet processing action, thereby determining The message processing action that needs to process the message.

网关用户面实体继续通过执行S1502，根据该Bearer对象实例的ID确定该Bearer对象的下一对象，即Flow对象，并依次通过执行S1503和S1501根据该Flow对象实例相关联的报文处理动作对报文进行处理，获得处理后的报文。若该Flow对象不是该对象集中的第一个对象，该Flow对象实例的报文处理次数为1。由于该Flow对象之前的对象，如该Bearer对象实例的报文处理次数大于1，则网关用户面实体可获得处理的报文可包括该Flow对象实例的ID，和计数标签值1。The gateway user plane entity continues to execute the S1502, and determines the next object of the Bearer object, that is, the Flow object, according to the ID of the Bearer object instance, and sequentially performs the message processing action report according to the Flow object instance by executing S1503 and S1501. The text is processed to obtain the processed message. If the Flow object is not the first object in the object set, the number of packets processed by the Flow object instance is 1. Due to the object before the Flow object, such as the message of the Bearer object instance If the number of processing times is greater than 1, the packet that can be processed by the gateway user plane entity may include the ID of the Flow object instance and the count label value 1.

网关用户面实体继续通过执行S1502，根据Flow对象实例的ID确定该该Flow对象的下一对象，即Bearer对象，并依次通过执行S1503和S1501确定Bearer对象实例相关联的报文处理动作为OperationMatch的报文处理动作，并根据OperationMatch的报文处理动作对报文进行动作匹配，确定Charge报文处理动作，继而根据Charge报文处理动作对报文进行处理，得到处理后的报文。若该Bearer对象不是该对象集中的第一个对象，该Bearer对象实例对应的报文处理次数大于1，则该网关用户面实体可获得处理后的报文包括：Bearer对象实例的ID和计数标签值2。The gateway user plane entity continues to perform the S1502, determines the next object of the Flow object according to the ID of the Flow object instance, that is, the Bearer object, and sequentially determines, by executing S1503 and S1501, that the packet processing action associated with the Bearer object instance is OperationMatch. The message processing action is performed, and the action of the message is matched according to the message processing action of OperationMatch, and the action of the tag message is determined, and then the message is processed according to the action of the tag message, and the processed message is obtained. If the Bearer object is not the first object in the object set, and the number of packets processed by the Bearer object instance is greater than 1, the processed message of the gateway user plane entity may include: the ID of the Bearer object instance and the count label. The value is 2.

当网关用户面实体在此执行S1502，根据Bearer对象实例的ID确定该Bearer对象不具有下一对象，则网关用户面实体退出执行该报文处理方法。When the gateway user plane entity executes S1502 here, according to the ID of the Bearer object instance, it is determined that the Bearer object does not have the next object, and the gateway user plane entity exits to execute the packet processing method.
