1. A method of receiving a point-to-multipoint service by a mobile terminal belonging to a mobile terminal group corresponding to the point-to-multipoint service, the method comprising:
- receiving on a broadcast channel, in a specific System Information Block (SIB), configuration information relating to a control channel only for the point-to-multipoint service;
receiving on the control channel a Radio Resource Control (RRC) radio bearer (RB) message that corresponds to the mobile terminal group, the RRC RB message including channel information and layer information for configuring a packet data convergence protocol (PDCP) layer and a Radio Link Control (RLC) layer;
processing the RRC RB message; and
based on the channel information and layer information in the RRC RB message, receiving the point-to-multipoint service, only at a mobile terminal belonging to the mobile terminal group, on a traffic channel that is a data channel only for the point-to-multipoint service, wherein the broadcast, control and traffic channels are logical channels between the RLC layer and a Medium Access Control (MAC) layer.
