Abstract: When zone allocation information of sub-bands is changed, a terminal receives a new MBS configuration message after a lifetime of an MBS configuration message at a time when the changed zone allocation information is received is expired. The terminal applies the changed zone allocation information at the beginning of the first MSI of the new MBS configuration message.

Abstract: PURPOSE: A management device of a base station, a method and a terminal thereof are provided to scan the around base station according to the previously agreed LDM pattern in the terminal while the base station is operated in LDM. CONSTITUTION: If a terminal MS(Mobile Station) in an active state does not exist in femto cell, a femto BS(Base Station) performs a LDM(Low Duty operation Mode)(S601, S602). The femto base station transmits the LDM initiation and LDM information to an adjacent base station through backhaul(S610). The adjacent base station broadcasts or unicasts the LDM information to a terminal(S620). The terminal scans the femto base station operated in the LDM through the LDM information(S630).
