Embodiment Construction

[0028] On the basis of the three business flow sharing methods provided in the SIGTRAN standard protocol document, the active / standby method, the load sharing method and the broadcast method, the present invention proposes a service flow sharing method, that is, setting the priority of the link and According to the method of load sharing.

[0029] In the embodiment of the present invention, a signaling gateway (SG: Signaling Gateway) and a media gateway controller (MGC: Media Gateway Controller) are used as SIGTRAN physical entities at both ends of the connection, and there are multiple links between the SG and the MGC. Among them, the SG includes multiple SGPs, and the SGP is the logic implementation form of the SG; and the ASP is the logic implementation form of the MGC.

[0030] The most important feature of the embodiment of the present invention is that link priority is introduced, that is, if multiple links serve the same service processing process (serve the same AS), t...

Abstract

The present invention provides a method for realizing load sharing. The method includes the following steps: defining the priorities of several links between the two entities, and storing the information in the first entity; The link with the highest required priority is selected from the links connected to the process of the second entity, and the signaling is carried on the link; the signaling is transmitted to the second entity via the link, and the second entity is sent by the second entity. Process output after processing. On the basis of the three service flow sharing methods of the active / standby method, the load sharing method and the broadcasting method provided in the SIGTRAN standard protocol, the present invention also proposes a method for realizing the service flow sharing by using the link priority, which is more convenient for users. A method for selecting a service bearer is provided, so that the service switching is faster, and the flexibility of the system application is also improved.

Description

technical field [0001] The invention belongs to the technical field of signaling transmission, and in particular relates to a method for realizing load sharing by using link priority. Background technique [0002] The signaling transfer (SIGTRAN: Signaling Transfer) protocol consists of multiple adaptation layer protocol stacks, mainly including protocols such as M3UA / M2UA / V5UA / IUA. Various primitives and management messages in the signaling transmitted between the connected SIGTRAN entities are carried on the Stream Control Transport Protocol (SCTP: Stream Control Transport Protocol), which is used to control the flow of signaling between entities transmission. The data in the signaling transmitted between SIGTRAN entities can be carried on the SCTP protocol, and can also be carried on the Transmission Control Protocol (TCP: Transport Control Protocol). Data transmission is based on "connection", and "connection" can be regarded as a "channel" for data stream transmission...
