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.

Claims

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, wherein

the 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.

2. The mobile terminal device of claim 1, wherein the reservation signal generation unit is configured to generate the reservation signal that contains a quality of service (QoS) request of an application recognized at the mobile terminal device.

3. The mobile terminal device of claim 1, further comprising a unit for determining a number of packets to be transmitted per unit time according to a transmission rate of a traffic type notified from the base station.

4. The mobile terminal device of claim 1, wherein the transmission timing determination unit is configured to calculate an actual transmission timing according to an average transmission interval of a traffic type notified from the base station and a predetermined distribution.

5. The mobile terminal device of claim 4, wherein the transmission timing determination unit is also configured to update the actual transmission timing for not yet transmitted packets of a non-realtime type traffic, according to the average transmission interval that is periodically notified and received from the base station.

6. The mobile terminal device of claim 1, wherein the transmission unit is configured to transmit packets of the high priority level type traffic or the realtime type traffic using a resource amount allocated by the base station in accordance with the reservation signal when the priority level judging unit judges that the type of the traffic is a non-high priority level or a non-realtime type.

7. The mobile terminal device of claim 1, wherein the transmission unit is configured to transmit packets of the high priority level type traffic or the realtime type traffic using a transmission timing according to an average transmission interval or a transmission rate determined by the base station based on a remaining resource amount when the priority level judging unit judges that the type of the traffic is the non-high priority level or the non-realtime type, the remaining resource amount corresponding to an amount of resources remaining after resources are reserved for the traffic of the high priority level or the real time type.
