MOBILE COMMUNICATION HAND-OVER METHOD, MOBILE STATION DEVICE, AND BASE STATION DEVICE

摘要

PURPOSE:To suppress hand-over unstableness and reduce a load on the control by disconnecting an old connection cell line on detecting the difference between a level in simultaneous reception and a maximum level exceeding a specific level difference. CONSTITUTION:A control part 15 connected to a receiving circuit part 14 compares the reception levels of perch channels of respective cells with one another. Such as cell in which at the difference D' between a reception level R exceeding a 1st specific reception level R1 among measured reception levels R and the maximum reception level is less than the 1st specific level difference D1 is newly connected and a simultaneous communication mode is entered. Further, when the level difference D'' between the reception level R of plural cells in a simultaneous communication and the maximum reception level exceeds a 2nd specific level difference D2 larger than the 1st specific level difference D1, the old connection line which decreases in level is disconnected.
