Abstract
A method for operating a cellular communications system of a type that includes a first type of terminal having real-time transmission needs and a second type of terminal having nonreal-time transmission needs. The method includes the steps of (a) determining at periodic intervals a total amount of capacity required to service the first type of terminals; (b) subtracting the determined amount from a current maximum capacity; and (c) allocating all or some of the remaining capacity, if any, to one or more of the second type of terminals.
Claims23
A method for operating a wireless communications system of a type that comprises a plurality of wireless terminals capable of transmitting packet data and a base station for receiving the packet data, comprising the steps of:
- establishing a bidirectional control channel between the base station and individual ones of the wireless terminals such that each wireless terminal has its own bidirectional control channel;
- for a wireless terminal that has data to transmit to the base station, subsequently establishing a data channel between the base station and the wireless terminal having data to transmit;
- and
- transmitting packets of data from the wireless terminal to the base station over the established data channel under the direction of messages exchanged over the control channel that was established for that wireless terminal, wherein
- the step of transmitting is initiated upon an occurrence of at least one of a predetermined number of packets being stored in a memory of the wireless terminal or a packet being stored in the memory for a predetermined period of time.

- for a wireless terminal that has data to transmit to the base station, subsequently establishing a data channel between the base station and the wireless terminal having data to transmit;
- and
- transmitting packets of data from the wireless terminal to the base station over the established data channel under the direction of messages exchanged over the control channel that was established for that wireless terminal, wherein
- the step of establishing the bidirectional control channel between the base station and one of the wireless terminals occurs before the wireless terminal has a packet of data to transmit.
A method for operating a wireless communications system of a type that comprises a plurality of wireless terminals capable of transmitting packet data and a base station for receiving the packet data, comprising the steps of:
- establishing a bidirectional control channel between the base station and individual ones of the wireless terminals such that each wireless terminal has its own bidirectional control channel;
- for a wireless terminal having no packet data to transmit to the base station, operating in a control channel hold state wherein the control channel remains established;
- for a wireless terminal that has data to transmit to the base station, transitioning from the control channel hold state to a state wherein a data channel is established between the base station and the wireless terminal;
- and
- transmitting at least one packet of data from the wireless terminal to the base station over the established data channel under the direction of messages exchanged over the control channel that was established for that wireless terminal, wherein
- the step of transitioning from the control channel hold state is initiated upon an occurrence of at least one of a predetermined number of packets being stored in a memory of the wireless terminal or a packet being stored in the memory for a predetermined period of time.

A wireless communications system of a type that comprises a plurality of wireless terminals capable of transmitting packet data and a base station for receiving the packet data, comprising:
- means for establishing a bidirectional control channel between the base station and individual ones of the wireless terminals such that each wireless terminal has its own bidirectional control channel;
- for a wireless terminal having no packet data to transmit to the base station, a control means for operating the wireless terminal in a control channel hold state wherein the control channel remains established;
- for a wireless terminal that has data to transmit to the base station, said control means operating to transition the wireless terminal from the control channel hold state to a state wherein a data channel is established between the base station and the wireless terminal;
- and
- means for transmitting at least one packet of data from the wireless terminal to the base station over the established data channel under the direction of messages exchanged over the control channel that was established for that wireless terminal, wherein
- the means for transmitting operates in response to an occurrence of at least one of a predetermined number of packets being stored in a memory of the wireless terminal or a packet being stored in the memory for a predetermined period of time.
