APPARATUS AND METHOD FOR CONTROLLING RELAY MODE OF BASE STATION IN COMMUNICATION SYSTEM

摘要

PURPOSE: A method and an apparatus for controlling a relay mode of a base station in a communication system are provided to supply a relay service through switching a base station into a relay mode in case of disconnecting communication with a backhaul. CONSTITUTION: A base station transmits communication disconnection information to one or more terminals located in a service area in case of disconnecting communication with backhaul(201,203). The base station selects one base station as a target BS(Base Station)(205). The base station supplies a relay service through connection of the target base station(219).
