COMMUNICATION CONTROL SYSTEM, COMMUNICATION CONTROL METHOD, BASE STATION DEVICE AND MOBILE TERMINAL DEVICE
First Claim
1. A mobile terminal device for carrying out packet communications with a base station, comprising:
- a priority level judging unit configured to judge a priority level of a traffic and to judge a type of the traffic;
a reservation signal generation unit configured to generate a reservation signal for a transmission request to the base station only when the priority level judging unit judges that the type of the traffic is a high priority level or a realtime type;
a transmission unit configured to transmit the reservation signal generated by the reservation signal generation unit to the base station when the reservation signal generation unit generates the reservation signal; and
a transmission timing determining unit configured to determine transmission timing for packet transmission according to the average transmission interval or the transmission rate notified by the base station when the priority level judging unit judges that the type of the traffic is a non-high priority level or a non-realtime type, whereinthe transmission unit is configured to transmit packets of non-high priority level type traffic or non-realtime type traffic using the transmission timing determined by the transmission timing determining unit without transmitting the reservation signal, in a case where the priority level judging unit judges that the type of the traffic is the non-high priority level or the non-realtime type.

Abstract
In packet communications between a mobile terminal and a base station, the mobile terminal checks a priority level of a traffic and judges a type of the traffic, and transmits a reservation signal for a transmission request to the base station when the type of the traffic is a high priority level or realtime type, and does not transmits it when the type of the traffic is a low priority level or non-realtime type, while the base station determines a resource amount to be reserved for packet transmission according to a resource utilization state and the reservation signal for the traffic of the high priority level or realtime type, or an average transmission interval or transmission rate for the traffic of the low priority level or non-realtime type according to margins in remaining resources, and notifies the resource amount or the average transmission interval or transmission rate to the mobile terminal.
