Radio communication terminal, base station, handoff control method and base station control method capable of achieving handoff while continuing service such as broadcast service and/or multicast service

摘要

A radio communication terminal (AT) includes a communication section for performing a radio communication with a base station, and a controller. Before performing a handoff from a first base station to another peripheral base station while receiving service information delivered by the first base station, the controller checks a progress of sequence of the service information being received. Then, the controller performs a handoff control depending on the check result. When it is determined that reception of a packet having the sequence number being received is to be completed within a certain time as a result of checking the progress, the controller suspends the handoff until the reception of the packet is completed.
