A resource allocation method of a relay line for call processing and a system and device thereof are provided to enable an MSC(Mobile Switching Center) to re-demand resource reservation to an MGW(Media Gateway) if a response for failure of the resource reservation is received from the MGW, thereby solving call processing malfunction caused by a trouble of a particular SSP(Switching Service Processor). The first mobile communication terminal(110) sends a communication call. The second mobile communication terminal(112) receives the communication call. MSCs(140,142) allocate resources to a specific one of relay lines(180,182) to relay the communication call to the second terminal, and reallocate the resources to the other of the relay lines if allocation of the resources to the particular relay line fails. |
