Method for improving service processing performance in M2PA protocol

Abstract

The invention relates to a method for improving the service treatment ability in M2PA protocol, which comprises: in the connection process of M2PA (two layer information transmission part second stage adaptive layer) chain circuit terminals, before checking said chain circuit is available, MTP3 (three layer information transmission part) sends MSU (message instruction unit) message, and the M2PA protocol stores said message; in the process that said connection, and after checking said chain circuit is available, M2PA protocol sends the stored message instruction unit MSU out. The invention can realize the connection process of M2PA protocol, reduce the loss possibility of M2PA chain circuit, strengthen the network and improve the service treating property of M2PA protocol.

Description

technical field [0001] The invention relates to a signaling system in the modern communication field, in particular to a method for improving the service processing performance in the M2PA protocol. 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 Management Network), SS7 signaling protocol stack includes MTP1, MTP2, MTP3, SCCP, TCAP, I...

Problems solved by technology

[0017] The disadvantage of the above docking process is: after receiving the "RPR" message, after the time point T1, the MTP3 at the B side considers that the M2PA link has returned to normal and can begin to transmit user data messages normally, but the entire M2PA link The user data message can only be transmitted normally after the B terminal receives the "Link StatusReady" message responded by the A terminal, that is, after the time point T2

Therefore, if MTP3 sends an MSU (Message Signaling Unit) message to request the M2PA link to start transmitting user data messages during the time point T1 to time point T2, the M2PA link will discard the MSU message sent by MTP3, As a result, user data messages are lost and the performance of M2PA link service processing is degraded.
