Mobile station, base station, communications system, and communication method
A mobile station comprises a reception unit configured to receive a signal transmitted from a base station; a selection unit configured to select a communication area to perform communication from a plurality of communication areas based on traffic load in the plurality of communication areas where the reception unit can receive the signal; and a notification unit configured to notify the base station of the communication area selected. Another mobile station comprises a reception unit configured to receive a signal transmitted from a base station; a calculation unit configured to calculate a ratio of an average reception quality value over a short period to an average reception quality value over a long period; and a selection unit configured to select a communication area to perform communication from a plurality of communication areas where the reception unit can receive the signal, based on the ratio.
1. A mobile station comprising:
a reception unit configured to receive a signal transmitted from a base station;
a calculation unit configured to calculate a ratio of an average reception quality value of a reception quality of the received signal over a first period of time to an average reception quality value of the reception quality of the received signal over a second period of time longer than the first period as a calculated reception quality of the received signal received by the reception unit; and
a selection unit configured to select a communication area to perform communication from a plurality of communication areas where the reception unit can receive the signal, based on the ratio calculated by the calculation unit.
2. A base station comprising:
a calculation unit configured to calculate a ratio of an average reception quality value of a signal received at a mobile station over a first period of time to an average reception quality value of a signal received at the mobile station over a second period of time longer than the first period as a reception quality of a received signal when a signal transmitted from the base station is received by the mobile station; and
a selection unit configured to select a communication area where the mobile station performs communication, from a plurality of communication areas where the mobile station can receive the signal, based on the ratio calculated by the calculation unit.
3. A communication method, comprising:
calculating a ratio of an average reception quality value of a signal received at a mobile station over a first period of time to an average reception quality value of a signal received at the mobile station over a second period of time longer than the first period as a reception quality of a received signal when a signal transmitted from a base station is received by mobile station; and
selecting a communication area where the mobile station performs communication, from a plurality of communication areas where the mobile station can receive the signal, based on the calculated ratio.
