Realization method for improving establishing M2PA link efficiency

Abstract

The invention relates to a realization method for improving the efficiency of establishing M2PA (second-level peer-to-peer adaptation layer of the second layer message passing part) link. The method includes: a processor fault occurs at an end point of an M2PA link during the link building process, and after the verification process of the end point is completed, a processor fault message and a link ready message are sent to the opposite end point of the link; After the processor failure recovery occurs at the endpoint of the faulty M2PA link, the endpoints at both ends of the M2PA link can directly use the link to transmit services after completing the processor failure recovery process. Using the method of the present invention, when a processor failure occurs during the M2PA link building process, the link building result will not be affected, and the link will not be rebuilt. After the processor recovers, it can directly use the link to transmit services, which improves the use efficiency of the M2PA link.

Description

technical field [0001] The present invention relates to a signaling system in the modern communication field, and in particular to a method for improving the efficiency of establishing an M2PA (second-level peer-to-peer adaptation layer for message passing part of the second layer) link. Background technique [0002] Signaling system is the key technology of modern communication network and the nervous system of PSTN (Public Switched Telephone Network). The reliable transmission of signaling messages by telecommunication equipment is the key to ensure high availability of telecommunication network. In the traditional telecommunication network, there are already a series of mature specifications and technologies to ensure the reliability of the signaling system, such as the No.7 (No. 7 signaling system) signaling system, and the No.7 signaling network is the three major supports of modern communication Network (Digital Synchronization Network, NO.7 Signaling Network, Telecom ...

Problems solved by technology

[0027] The disadvantage of the processing method when a processor failure occurs during the M2PA link building process in the above prior art is: if an M2PA link is in the chain building process, and a processor failure occurs at the endpoint, the endpoints at both ends of the link After the locating process is completed, even if the endpoint recovers from a processor failure, this M2PA link cannot be used for a period of time, at least until the next link is successfully established before using this link to transmit services, resulting in Reduces the delay of M2PA link transmission services, the loss of processing performance, and reduces the use efficiency of M2PA links
