Disclosed are a radio communication base station device and a radio
communication method which can reduce the interruption time of a service
being received by UE while suppressing a resource consumption amount in
an SFN area when the UE performs a handover from the SFN area to a
non-SNF area. An MBMS reception request identification unit (127) judges
an RRC message inputted from the UE (100). If an MBMS reception request
is contained, an MBMS reception request is transmitted to an MBMS
reception request storage unit (124). Moreover, when the RRC message from
the UE (100) contains an adjacent cell reception quality measurement
result, a handover decision unit (126) judges whether to perform a
handover to the adjacent cell. The MBMS reception request storage unit
(124) stores the MBMS reception request outputted from the MBMS reception
request identification unit (127). When the handover decision unit (126)
which has decided the handover requests for transmission of an MBMS
reception request, the MBMS reception request storage unit (124)
transmits the MBMS reception request to an MME (140).
