SIGNAL MESSAGE PING-PONG ERROR PREVENTING DEVICE OF THE NO.7 SIGNAL NETWORK SYSTEM AND CONTROLLING METHOD THEREFORE

摘要

The invention NO.7 in a network system having a subsystem for transmitting and receiving data in a signal network, to the NO.7 signaling message with reference to the MTP routing tables using the signaling network to process and analyze the received signal message transmission checking whether the sub-system, signals that when an error correction request signal for a particular sub-system is input from the MTP block and the MTP block to perform error correction notification of the abnormal signal message updates the routing table information of all the sub-system message signal of the number seven network signaling system comprising a network management unit ping-pong error protection to provide an apparatus and a control method thereof.; The present invention as described above is written because analyzes the content of the signaling messages which are sent and received between subsystems operating in a No.7 signaling network, and update the routing tables of all subsystems out to quickly detect a failure of the MTP routing tables, certain sub- to rapidly prevent the error in the ping-pong occurs in the form of system prevents unnecessary consumption of resources, so there can be used efficiently than the finite resources of the system accordingly NO.7.
