Abstract: PURPOSE: A method for automatically adjusting signal route priority in No.7 signaling network is provided to improve utilization and efficiency by optimizing a priority by defining an MHT and an MHA message and their parameter and performing a testing for the whole available signal route from a call origination signaling point to a destination signaling point according to a state change of a signaling network without an intervention. CONSTITUTION: Assuming that every signal route from a signaling point 'A' to a signaling point 'F' is available, a message transmitting unit of the signaling point 'A' detects signal route available to a destination signaling point 'F'(S101) and performs an available processing procedure for the detected signal route(S102). The message transmitting unit determines whether more than two signal routes available to the destination signaling point 'F'(S103). If more than two signal routes exist, the message transmitting unit of the signaling point 'A' transmits an MHT message for the signal route available to the detected destination signaling point 'F'(S104). The message transmitting unit of the signaling point 'A' transmits the MHT message and at the same time generates a timer of a predetermined time set for defining time waiting for receiving an MHA message, a response message for the MHT message from the destination signaling point 'F', to thereby perform counting of a pre-set time(S105). When the MHA message is received through an arbitrary available signal route from the destination signaling point 'F'(S106), the MHA information containing information on the corresponding signal rout is stored in a memory unit(S107). It is determined whether the whole MHA message is completely received for the MHT transmitted for the signal route available at the signaling point 'A'(S108). If it is determined that the MHA message is completely received from the whole available signal route, the operation of the timer is cleared(S109). The message transmitting unit of the signaling point 'A' analyzes the information of the MHA stored in the memory unit to determine priority of the received signal routes, and re-adjusts the priority of the signal routes for message transmission from the signaling point 'A' to the destination signaling point 'F'.
