Wireless communication system, neighbor cell list optimizing system, base station, neighbor cell list updating method, and program

摘要

A first mobile terminal group has a first measurement information transmitting means which measures radio quality of a second cell, and transmits measurement information to a first base station, a second mobile terminal group has a second measurement information transmitting means which measures radio quality of a first cell, and transmits measurement information to a second base station, and a neighbor cell list optimizing system has: a measurement information collecting means which collects the measurement information of the first and second cells; a reliability evaluating means which performs processing of evaluating reliability of the measurement information of the second cell; a priority calculating means which, when the reliability is a predetermined threshold or less, calculates a priority for registering the second cell in the neighbor cell list of the first cell based on the measurement information of the first cell; and a neighbor cell list updating means which performs control of determining a neighbor cell to be registered based on the priority, and updating the neighbor cell list.

主权项

1. A wireless communication system comprising:
a first mobile terminal group; a first base station which manages a first cell in which the first mobile terminal group exists; a second mobile terminal group which exists in a second cell which is neighboring to the first cell; a second base station which manages the second cell; and a neighbor cell list optimizing system which manages a neighbor cell list in which a specific neighbor cell which is a handover destination candidate of the first mobile terminal group is registered, wherein: the first mobile terminal group comprises a first measurement information transmitting unit which measures radio quality of the second cell, and transmits measurement information of the second cell to the first base station; the second mobile terminal group comprises a second measurement information transmitting unit which measures radio quality of the first cell, and transmits measurement information of the first cell to the second base station; and the neighbor cell list optimizing system comprises: a measurement information collecting unit which collects the measurement information of the second cell from the first base station, and collects the measurement information of the first cell from the second base station; a reliability evaluating unit which performs processing of evaluating reliability of the measurement information of the second cell; a priority calculating unit which, when the reliability is a predetermined threshold or less, calculates a priority for registering the second cell in the neighbor cell list of the first cell based on the measurement information of the first cell; and a neighbor cell list updating unit which performs control of determining a neighbor cell to register in the neighbor cell list, based on the priority calculated by the priority calculating unit, and updating the neighbor cell list.
