Abstract
A radio communication system in which a mobile relay station includes a notification unit configured to notify the mobile station of mobility state information of the mobile relay station determined based on a number of base stations selected within a specified time, and the mobile station includes a base station selection processing unit to select the base station based on the mobility state information when the mobile station switches a device to be communicated with from the mobile relay station to the base station.
Claims8
A radio communication system comprising:
- a plurality of base stations;
- a mobile relay station configured to
- select a base station from among the plurality of base stations,
- relay radio communication between the selected base station and a mobile station, and
- notify the mobile station of mobility state information of the mobile relay station determined based on a number of base stations selected within a specified time;
- and
- the mobile station configured to select a base station based on the mobility state information when the mobile station switches a device to be communicated with from the mobile relay station.
A mobile relay station to relay radio communication between a base station and a mobile station, the mobile relay station comprising:
- a processor configured to
- select a base station from among a plurality of base stations, and
- determine mobility state information of the mobile relay station based on a number of base stations selected by the processer within a specified time;
- and
- a transmitter to notify the mobile station of the mobility state information of the mobile relay station.
A mobile station that performs radio communication with a base station, which is relayed by a mobile relay station, the mobile station comprising:
- a receiver configured to receive mobility state information determined based on a number of base stations selected by the mobile relay station within a specified time, the mobility state information indicating the mobility state of the mobile relay station;
- and
- a selector to select a base station based on mobility state information when a device to be communicated with the mobile station is switched from the mobile relay station.
A radio communication method of a mobile station that performs radio communication with a base station, which is relayed by a mobile relay station, the method comprising:
- receiving mobility state information determined based on a number of base stations selected by the mobile relay station within a specified time, the mobility state information indicating the mobility state of the mobile relay station;
- and
- selecting a base station based on the mobility state information when a device to be communicated with the mobile station is switched from the mobile relay station.
