Abstract
There is disclosed a mobile station performing packet communications with a base station, including: a reservation control signal generating unit configured to generate a reservation control signal, based on control information transmitted in advance of a data packet; and a reservation control signal transmission control unit configured to transmit the reservation control signal at a predetermined timing.
Claims15
A mobile station performing packet communications with a base station, comprising:
- a reservation control signal generating unit configured to generate a reservation control signal, based on control information transmitted in advance of a data packet;
- and
- a reservation control signal transmission control unit configured to transmit the reservation control signal at a predetermined timing.
A base station performing packet communications with a mobile station, comprising:
- a traffic measurement unit configured to measure traffic on an uplink channel from the mobile station to the base station;
- a traffic determination unit configured to determine whether the base station can accept a reservation control signal from the mobile station, based on a condition of the measured traffic on the uplink channel;
- and
- a control signal generating/transmission unit configured to generate and transmit a control signal for preventing the mobile station from transmitting the reservation control signal, based on the result of the determination.
A mobile communication system including a mobile station and a base station performing packet communications with the mobile station, wherein:
- the base station comprises
- a traffic measurement unit configured to measure traffic on an uplink channel;
- a traffic determination unit configured to determine whether the base-station can accept a reservation control signal from the mobile station, based on a condition of the measured traffic on the uplink channel;
- and
- a control signal generating/transmission unit configured to generate and transmit a control signal for preventing the mobile station from transmitting the reservation control signal, based on the result of the determination;
- and
- the mobile station comprises
- a reservation control signal generating unit configured to generate the reservation control signal, based on control information transmitted in advance of a data packet;
- and
- a reservation control signal transmission control unit configured to transmit the reservation control signal at a predetermined timing, when a transmission grant for the reservation control signal to the base station is accepted.
A communication control method in a mobile communication system including a mobile station and a base station performing packet communications with the mobile station, comprising the steps of:
- detecting a request for data transmission;
- generating a reservation control signal,
- based on control information transmitted in advance of a data packet;
- and
- transmitting the reservation control signal at a predetermined timing.
