Claim of US Patent No. 9,432,203

1. A method in which a mobile terminal configures a broadcast zone to provide a broadcast service, the method comprising:
calculating quality values of signals received from a plurality of base stations by a channel information collector; and
selecting by a Multicast Broadcast Service (MBS) zone configuration unit one or more base stations that are to configure a
multicast and broadcast service (MBS) zone, from among the plurality of base stations, based on the quality values of the
received signals,

receiving information about member base stations that participate in a MBS zone, MBS program information and MBS channel information
from a MBS server and a gateway;

configuring a MBS information table including the information about the member base stations and the MBS program information
by a terminal MBS information table configuration unit,

comparing information about the member base stations belonging to a newly configured MBS zone to information about the member
base stations belonging to a previously configured MBS zone by the MBS zone configuration unit, and

transmitting, if the newly configured MBS zone includes at least one member base station that is identical to none of the
member base stations of the previously configured MBS zone, a MBS zone configuration request message to the serving base station.
