Abstract: A method of automatically assigning a signaling terminal in a mobile communication system comprising the steps of: receiving an alarm from an SSFA and determining whether the SSFA is connected or removed according to information data of the received alarm; when the SSFA is removed, obtaining an SLP value of a signaling link to which a signaling terminal in the removed SSFA is assigned and determining whether or not there exists an alternative signaling terminal which is not assigned to any signaling link and in a normal state in connected SSFAs; when the alternative signaling terminal is found, updating the value of the SLP of the signaling link to which the signaling terminal of the removed SSFA has been assigned with the alternative signaling terminal in a database and activating the signaling link to which the alternative signaling terminal is newly assigned; when the SSFA is connected, testing loop of a signaling terminal to determine whether or not the signaling terminal is in the normal state; and when

Abstract: An improved common-channel message conversion method for a communication network interface between exchange systems which is capable of directly interfacing a DCN network and AMPS network by converting different message formats of a common-channel signalling method of a DCN network and AMPS network in one exchange system and coinciding different parameter values and operation between hierarchical structures.
