Patent ID: 7409215

Claim:
A mobile communication terminal for use in a cellular mobile communication system, comprising: a circuit configured to acquire a first neighbor list from a first base station serving the mobile communication terminal in a standby mode, the first neighbor list storing data indicating a first plurality of peripheral base stations existing near the first base station; a memory configured to store the acquired first neighbor list; a circuit configured to acquire, if the serving base station is handed off in a standby mode from the first base station to a second base station, a second neighbor list from the second base station that is the serving base station after the handing-off, the second neighbor list storing data indicating a second plurality of peripheral base stations existing near the second base station; a circuit configured to additionally store the acquired second neighbor list in the memory; a setting circuit configured to set priority levels for the peripheral base stations listed in the first and second neighbor lists stored in the memory; a measurement circuit configured to measure, when the mobile communication terminal and the second base station are synchronized with each other, communication quality between the mobile communication terminal and each of the peripheral base stations listed in the first and second neighbor lists, in a decreasing order of priority level set by the setting circuit; and a circuit configured to select, as a hand-off destination candidate, one station from the first plurality of peripheral base stations indicated in the first neighbor list and the second plurality of peripheral base stations indicated in the second neighbor list, which satisfies a preset condition, based on the measured communication quality, wherein the first neighbor list and the second neighbor list are combined without determining characteristics of the serving base station and corresponding cell, and the memory stores the first neighbor list until a total number of occasions in which selection for selecting the hand-off destination candidate is performed reaches a preset value, and the first neighbor list is erased from the memory after the total number of occasions reaches the preset value.
