Abstract: PURPOSE: A dynamic allocation method of a user terminal and a dynamic allocation system thereof are provided to select a base station in order for a user terminal to make optimal performance and to increase the performance of the entire system. CONSTITUTION: A plurality of user terminals includes a base station and calculates performance variation of the entire network based on the number of user terminals (S306). In case the calculated performance variation is greater than a critical value (S308), the user terminal requests handover to the base station (S310). The base station processes whether to perform handover (S316). [Reference numerals] (300) UE (user terminal); (400) Current base station which receives a service; (500) Target base station which requires a handover; (AA) Yes; (BB) No; (CC) Request the handover to the corresponding base station; (DD) Transfer the handover request to the target base station; (EE) Handover acceptance screen; (FF) Handover acceptance reply; (GG) End; (S302) Transmit information on the number of users who use the service; (S304) Receiving; (S306) Calculate performance variation of the adjacent base stations; (S308) The performance variation > a critical value?; (S312) Select a user terminal for providing maximum perfomance variation; (S316) Perform the handover
