Problems solved by technology

[0004] However, as users' demand for the Internet increases, the gateway moves down closer to the user, which leads to a sharp increase in the number of gateways, for example, from one PGW per province to one PGW per county. The configuration, update, and maintenance of the library will generate a large amount of homogeneous maintenance work, increasing the operation and maintenance cost of the network

Embodiment 1

[0091] Embodiments of the present invention provide a method for processing data packets, such as image 3 shown, including:

[0092] 101. The gateway control device receives the packet characteristic information of the first packet sent by the gateway forwarding device, where the packet characteristic information is obtained after the gateway forwarding device parses the first packet.

[0093] 102. The gateway control device searches a pre-stored policy library for a first processing policy corresponding to the packet feature information according to the packet feature information of the first packet.

[0094] 103. The gateway control device sends the first processing policy to the gateway forwarding device, so that the gateway forwarding device executes a packet processing action in the first processing policy.

[0095] In step 101, after the gateway forwarding device receives the first message, it analyzes the first message to obtain the message characteristic information ...

Embodiment 2

[0126] based on Figure 4 As shown in the forwarding model of the gateway forwarding device and the gateway control device, the embodiment of the present invention provides a method for processing data packets, such as Figure 7 As shown, wherein, the message characteristic information of the first message includes the characteristic information of the third layer and the fourth layer of the first message in the OSI model, and the method specifically includes:

[0127] 301. The gateway forwarding device acquires quintuple information of the first packet.

[0128] 302. If the processing policy corresponding to the quintuple information is not stored in the gateway forwarding device, the gateway forwarding device analyzes the third layer and fourth layer messages in the OSI model to obtain the first The characteristic information of the third layer and the fourth layer of the packet in the OSI model.

[0129] 303. The gateway forwarding device sends the characteristic informat...

Embodiment 3

[0160] based on Figure 5 For the forwarding model of the gateway forwarding device and the gateway control device shown, before step 303 in the above-mentioned embodiment 2 is executed, as Figure 8 As shown, the message exchange method between the gateways may also include the following steps 401-405, wherein:

[0161] 401. The gateway control device sends at least one third processing policy in the policy library and an execution condition of the third processing policy to the gateway forwarding device.

[0162] 402. The gateway forwarding device saves the at least one third processing policy and an execution condition of the third processing policy.

[0163] 403. After the gateway forwarding device obtains the quintuple information of the first message, if the gateway forwarding device does not store a processing policy corresponding to the quintuple information, the gateway forwarding device performs OSI model processing on the first message. The layer 3 and layer 4 pac...

Abstract

Embodiments of the present invention provide a method, device, and system for processing data packets, which relate to the field of communication. The policy library is deployed on the gateway control device uniformly, and the message identification and policy execution are deployed on each gateway forwarding device, so as to effectively Control the cost of network operation and maintenance. The solution includes: the gateway control device receives the message feature information of the first message sent by the gateway forwarding device, and the message feature information is obtained after the gateway forwarding device parses the first message; the gateway control According to the message feature information of the first message, the device searches the pre-stored policy library for the first processing policy corresponding to the message feature information; the gateway control device sends the first processing policy to the gateway forwarding device , so that the gateway forwarding device executes the packet processing action in the first processing policy.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for processing data messages. Background technique [0002] LTE (Long Term Evolution, Long Term Evolution), as the evolution direction of 3G technology, has become the mobile network evolution goal of the mainstream mobile operators in the world. The international standard organization 3GPP has proposed a complete next-generation network evolution architecture, that is, an EPC (Evolved Packet Core, evolved packet core network) architecture. [0003] Among them, the EPC architecture mainly includes MME (Mobility Management Entity, mobile management entity), HSS (Home Subscriber Server, home subscriber server), PCRF (Policy and Charging RulesFunction, policy and charging rule functional unit) and many gateways, such as , TGW (Trusted access gateway, trusted access gateway), SGW (Serving Gateway, serving gateway), PGW (Packet Data Network Gateway, packe...
