<P>PROBLEM TO BE SOLVED: To reduce, by a method other than adding an FNG or improving a processing capability, a multicast packet processing load occurring at a core network device FNG at the time of BCMCS distribution in a femtocell system. <P>SOLUTION: A femtocell base station does not receive BCMCS data from an FNG but receives the BCMCS data notified through a radio wave by a macrocell base station located at the periphery of a femtocell base station installation site, at the same time stores the data once in the femtocell base station, and re-distributes the data to a mobile station waiting in the femtocell base station through a radio wave of the femtocell base station. <P>COPYRIGHT: (C)2013,JPO&INPIT |
