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

Embodiment Construction

[0054] The invention provides a realization method for improving the efficiency of creating M2PA links. The core of the present invention is:

[0055] During the establishment of the M2PA link, if the endpoint of the M2PA link receives a Processor Outage (processor failure) message from the peer endpoint, the verification process of the endpoint ends and it receives the Ready ( After the link is ready) message, report the In Service (enter service state) primitive and the RPO (remote processor failure) primitive to the upper layer protocol MTP3 of this endpoint.

[0056] After receiving the Processor Recover (processor failure recovery) message from the opposite end point and completing the processor failure recovery, the link enters the service state, and the upper-layer users MTP3 at both ends can use the link to transmit services.

[0057] The specific processing flow of the method of the present invention is as image 3 shown, including the following steps:

[0058] Ste...

Abstract

The invention discloses an efficiency improving realizing method of M2PA (two layer information transmission part second image adapting layer) chain, which comprises the following steps: when the end of M2PA chain occurs disposal accident in the chain-building course, it sends accident information and chain preparing information to chain end-to-end end after the end is detected; two-end points of M2PA chain finishes recovery for processor, which uses chain transmission business directly. The invention doesn't influence chain-building result, which improves utility efficiency of M2PA chain.

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 ...
