<p>PROBLEM TO BE SOLVED: To allow a mobile station device to appropriately receive data concerning communication even in circumstances where handover is performed.SOLUTION: In a communication method: a mobile station device 10-1 regularly receives an annunciation signal from a peripheral base station device and reports a reception level of the received annunciation signal to the base station device 20-1; the base station device 20-1 determines to cause the mobile station device to perform handover to a base station device 20-2 based on the report from the mobile station device and transmits a handover request to a PDSN 30; the PDSN 30 transfers the handover request to the base station device 20-2; the base station device 20-1 transmits a handover instruction to the mobile station device 10-1; the mobile station device 10-1 that receives the handover instruction establishes a communication channel with the base station device 20-2; the base station device 20-1 holds mobile station device information for a predetermined time and transmits data to the mobile station device 10-1 from the PDSN until the predetermined time has elapsed.</p> |
