Abstract
A wireless communication system is provided including a first base station, and a second base station having a coverage area at least one part of which overlaps a coverage area of the first base station. The communication system includes a measurer that measures a utilization degree of at least one mobile station connected to the second base station, and an adjuster that adjusts a wireless resource allocation of the at least one mobile station connected to the second base station based upon the utilization degree.
Claims17
A wireless communication system comprising:
- a macro base station;
- and
- a femto base station having a coverage area at least one part of which overlaps a coverage area of said macro base station,
- wherein the wireless communication system comprises:
- a measurer that measures an amount of data communicated between each of a plurality of mobile stations and said femto base station, and calculates a utilization degree of each of said plurality of mobile stations based on the amount of data measured for each of the plurality of mobile stations, respectively;
- and
- an adjuster that adjusts a wireless resource allocation of at least one mobile station of said plurality of mobile stations so as not to perform a handover to a macro base station when said utilization degree of said at least one mobile station exceeds a predetermined threshold.
A femto base station having a coverage area at least one part of which overlaps a coverage area of a macro base station, comprising:
- a measurer that measures an amount of data communicated between each of a plurality of mobile stations and the base station, and calculates a utilization degree of each of the plurality of mobile stations based on the amount of data measured for each of the plurality of mobile stations, respectively;
- and
- an adjuster that adjusts a wireless resource allocation of at least one mobile station of said plurality of mobile stations so as not to perform a handover to a macro base station when said utilization degree of said at least one mobile station exceeds a predetermined threshold.
A management server in a wireless communication system that comprises a macro base station and a femto base station having at least one part of which overlaps a coverage area of said macro base station, said management server connected to said femto base station via a network, said management server comprising:
- a measurer that measures an amount of data communicated between each of a plurality of mobile stations and said femto base station, and calculates a utilization degree of each of said plurality of mobile stations based on the amount of data measured for each of said plurality of mobile stations, respectively;
- and
- an adjuster that instructs said femto base station to adjust a wireless resource allocation of at least one mobile station of said plurality of mobile stations so as not to perform a handover to a macro base station when said utilization degree of said at least one mobile station exceeds a predetermined threshold.
A wireless communication method in a wireless communication system comprising:
- a macro base station;
- and
- a femto base station having a coverage area at least one part of which overlaps a coverage area of said macro base station
- wherein said wireless communication method comprises
- measuring an amount of data communicated between each of a plurality of mobile stations and said femto base station;
- calculating a utilization degree of each of said plurality of mobile stations based on the amount of data measured for each of the plurality of mobile stations, respectively;
- and
- adjusting a wireless resource allocation of at least one mobile station of said plurality of mobile stations so as not to perform a handover to a macro base station when said utilization degree of said at least one mobile station exceeds a predetermined threshold.
A computer-implemented wireless communication method of a femto base station having a coverage area which at least partially overlaps a coverage area of a macro base station, said wireless communication method comprising executing on a processor:
- measuring an amount of data communicated between each of a plurality of mobile stations and said femto base station;
- calculating a utilization degree of each of said plurality of mobile stations based on the amount of data measured for each of the plurality of mobile stations, respectively;
- and
- adjusting a wireless resource allocation of at least one mobile station of said plurality of mobile stations so as not to perform a handover to a macro base station when said utilization degree of said at least one mobile station exceeds a predetermined threshold.
