Abstract:
A signal route control method for a No. 7 signaling network, comprising:transmitting a Message Transfer Part (MTP) Hop Test (MHT) message over each of a plurality of available signal routes after detecting available signal routes to a test ending signaling point; transferring each MHT message to a test ending signaling point over the available signal routes when the signaling point receiving the MHT message is not the test ending signaling point; generating and transmitting to a test starting signaling point a MTP Hop Acknowledgment (MHA) message as an answer message corresponding to each MHT message sent over the available signal routes when the signaling point receiving the MHT message is the test ending signaling point; and controlling a priority order of the plurality of available signal routes using message information provided in each MHA message detected after the test starting signaling point receives each MHA message, wherein the MHT Message comprises a Hop Count as a major parameter; wherein the Hop Count increases by a prescribed value each time the MHT message passes through a transit signaling point, until the MHT message reaches the test ending signaling point; and wherein the MHA message information comprises a value of the Hop Count at the test ending signaling point.
