Abstract:
1. A method for detecting a circular routing in a No. 7 signaling network which is connected to any of a number of destination points and a number of signaling transfer points at a close or long distance, comprising: determining an unavailable state of a link directly connected to a destination point at any of the signaling transfer points; selecting available signal routes having the destination point as a destination, if the link directly connected to the destination point is unavailable, as a result of said determination; transmitting a message transfer part routing verification test (MRVT) message via a specific signal route among the available signal routes according to an order of priority; and detecting a corresponding signal route as in a normal state or in a circular routing state according to a response message, after receiving the response message from the signaling transfer point that received the MRVT message.
