摘要

PURPOSE: A method for searching information of a different subscriber by an RAU(Radio Access Unit) in a mobile communication system is provided to allow an MST(Mobile Subscriber Terminal) to recognize a cause of incapability of call processing by checking information on different subscribers. CONSTITUTION: An MST requests subscriber information from an RAU of an area where the MST itself belongs(1001). The RAU receives a subscriber information request signal from the MST(1002). The RAU analyzes the subscriber information request signal and then transmits information on different MSTs that have subscribed for the communication area of the RAU(1003). The MST receives information on the subscribers and stores it in a memory(1004). The MST checks whether a desired subscriber exists from the information on the subscribers stored in the memory(1005).
