Method for controlling signaling message flow quantity

Abstract

The present invention provides a method for controlling signaling message flux in repeat circuit service process, including that: a signaling transfer point transmits admission transfer message to a signaling terminal; the signaling terminal transmits unavailable message of user parts to all reachable terminal signaling points; the message transfer part of all reachable terminal signaling points transmit a first indication primitive to user parts for notifying the unavailability of user parts, the user parts close all repeat circuits with the signaling terminals. The message transfer part of signaling terminal transmits a second indication primitive to user part of signaling terminal, and the user part can transmit signaling message to reachable terminal signaling points; and user parts store the coding of reachable terminal signaling points, and select reachable terminal signaling point one by one in a certain time for performing repeat circuit recovery operation, and review process after starting repeat circuit, thereby controlling effectively interaction of congestion message between signaling points.

Description

technical field [0001] The invention relates to the field of fixed network communication, more specifically, to a method for controlling signaling message flow during the activation process of a relay circuit. Background technique [0002] The traditional signaling network is mainly composed of signaling points and signaling links. The signaling point is generally divided into a signaling end point (Signaling End Point, SEP) and a signaling transfer point (Signaling TransferPoint, STP). SEP is a node that processes control messages, where the signaling point that generates the message is the originating point of the message, and the signaling point where the message arrives is the destination node of the message. STP has a signaling forwarding function, and forwards signaling messages from one signaling link to the signaling node of another signaling link. A signaling transfer point serving as a message to a destination will use the transfer-enable procedure to inform one ...

AI Technical Summary

Problems solved by technology

[0014] The problem caused by the above method is: when the signaling endpoint SEP is connected to many adjacent signaling points through one STP, once the signaling link between SEP and STP is normal, SEP will be reachable by many signaling points in a short time

Congestion control is useful for call initiation, but not ideal for circuit monitoring message flow control
