The multi-functional terminal selects a second back-off delay time (S350). The multi-functional terminal operates as the base station mode when the second back-off delay time finishes, unless the multi-functional terminal receives the preamble from another multi-functional terminal or a base station before the second back-off delay time finishes (S380). [Reference numerals] (AA,CC) Yes; (BB,DD) No; (S310) Select a first back-off delay time when entering a station mode and start a first back-off time; (S320) Whether or not a preamble is received from a different multi-functional terminal or the station?; (S330) Operate by a lower terminal; (S340) Transmit the preamble when the first back-off delay time finishes; (S350) Select the first back-off delay time and start a second back-off time; (S360) Whether of nor the preamble is received from the different multi-functional terminal or the station?; (S370) Operate by a lower terminal; (S380) Operate by the station mode when the second back-off time finishes

Abstract: PURPOSE: A terminal and a communication method thereof are provided to offer a wireless communication service even if a base station has damage. CONSTITUTION: A processor(132) of a terminal is connected to an RF(Radio Frequency) module(136). When the terminal applies electronic wave interference to a lower terminal, the processor controls the maximum transmission power of an uplink relay area and a maximum transmission power of a downlink access area. The size of the maximum transmission power in the downlink access area is smaller than the size of the maximum transmission power in the uplink relay area. The size of the maximum transmission power in the downlink access area is reduced before radio wave interference is generated. [Reference numerals] (132) Processor; (134) Memory; (136) RF module;

Abstract: PURPOSE: A method for controlling a power saving mode of a mobile communication system is provided to lengthen a paging cycle according to a battery remaining amount or by a user, thereby lengthening a local update cycle. CONSTITUTION: A location managing server generates a new current paging cycle value based on received power saving mode information(S40).
