Signal message ping-pong error preventing device of the No.7 signal network system and controlling method therefore

摘要

The invention having the sub-system for sending and receiving data in a network system NO.7 signaling network, the NO.7 signaling network using the signaling message handling with reference to the MTP routing tables and check if the originating subsystem analyzes the received signal message and the MTP block to perform error correction of the abnormality notification signal message, The MTP block error correction request signal from the fail-safe device of the ping-pong message number seven signaling network system comprising a signaling network management unit to update the routing table information for all of the sub-system when the signal is input and the control method for a particular subsystem provides. ; The present invention as described above is No.7 analyze the content of signaling messages transmitted and received between subsystems operating in a signaling network, and taking it quickly and easily detect an error of the MTP routing tables every subsystem sikimeuro update the routing table in the writing, to prevent ping-pong quickly that a particular sub-system in the form of an error is generated to prevent the unnecessary consumption of resources can be used more efficiently, because the finite resources of NO.7 system accordingly.
