Problems solved by technology

To sum up, when the network elements on the control plane are congested, signaling messages are randomly discarded to alleviate the congestion problem. This will lead to the problem of discarding important signaling messages. The importance of each signaling message to deal with the countermeasures of each signaling message

Embodiment 1

[0059] like figure 1 As shown, the embodiment of the present invention provides a method for processing signaling messages, the method is as follows:

[0060] 101. The base station, MME, S-GW, P-GW, and SGSN acquire control plane management (Priority of Signaling, PoS) parameters, and the PoS parameters include the type of procedure (Type of Procedure, ToP) parameter, message level (Level of Message, LoM) Parameters and process control (Control of Procedure, CoP) parameters, where the ToP parameter is used to indicate the type of procedure, the LoM parameter is used to indicate the priority of messages of different procedures, and the CoP parameter is used to indicate the type of procedure that MME needs to control.

[0061] Wherein, the ToP parameter in the PoS parameter specifically indicates the type of the process, and the types of the process include a bearer establishment process, a bearer modification process, and a bearer deletion process. For example, when ToP=001, i...

Embodiment 2

[0187] Such as Figure 8 As shown, the embodiment of the present invention provides a system 80 for processing signaling messages, and the system 80 includes: a base station 801 , an MME 802 , an S-GW 803 , and a P-GW 804 .

[0188] The base station 801 is used to obtain PoS parameters; when the base station is congested, refer to the content indication of the PoS parameters, and send various signaling information; the PoS parameters include ToP parameters, LoM parameters and CoP parameters, where the ToP parameters are used to indicate the type of process , the LoM parameter is used to indicate the priority of messages of different processes, and the CoP parameter is used to indicate the type of process that the MME needs to control; when the base station 801 is congested, refer to the content indication of the PoS parameter to send various signaling information.

[0189] The MME802 is used to obtain the PoS parameters; when the MME802 is congested, it refers to the content i...

Abstract

The invention discloses a method and a system for processing signalling message, and relates to the field of a communication network technology. The method and the system are used for confirming the sent signalling message according to the importance of the signalling message when all network elements are in a congestion state in a control plane. The embodiment of the invention concretely comprises that a base station, a mobility management entity (MME), a service gateway (S-GW) and a packet data network gateway (P-GW) acquire PoS parameters, wherein the PoS parameters comprise a ToP parameter, an LoM parameter and a CoP parameter; the ToP parameter is used for indicating the types of the processes; the LoM parameter is used for indicating the priority of message in the different processes; the CoP parameter is used for indicating the types of the processes needed to be controlled by the MME; when any network element in the base station, the MME, the S-GW or the P-GW is in a congestion state, the network element having congestion refers to the indication of the content of the PoS parameters, and all the signalling message in the network element having congestion can be transmitted. The scheme provided by the embodiment of the invention is suitable for processing the signalling message when the network element of the control plane is in a congestion state.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method and system for processing signaling messages. Background technique [0002] As more and more users use mobile terminals to access the Internet, it is necessary for the operator's network to establish an end-to-end bearer for the services of its users. Usually, the bearer of the service is established on the user plane, which is used to transmit the data of the service, and the process of establishing, modifying and deleting the bearer of the service is completed through the interaction of signaling messages between network elements on the control plane . [0003] In the prior art, multiple mobility management entities (Mobility Management Entity, MME) / serving general packet radio support nodes (Serving GPRS Support Node, SGSN) are usually combined into a pool POOL. In a POOL, multiple MMEs (multiple SGSNs) are interconnected. When any network ele...
