Abstract

A system and method are provided for allocating wireless channels in a base station processor to messages sent between a subscriber and the base station processor in a wireless network. A latency period is determined corresponding to a return message to be received from a responsive node in response to an outgoing message sent from a sender via the base station processor. A latency manager in the base station processor computes the latency period and stores the latency period in an allocation table. A scheduler schedules a channel to be available at the end of the latency period indicated in the allocation table. At the end of the latency period, the return message is received and the scheduler allocates a channel as defined in the allocation table. The scheduled channel is used to transmit the message to or from the corresponding subscriber.

Claims

1. A wireless base station comprising:

circuitry configured to communicate internet protocol (IP) data with a subscriber unit, wherein

the circuitry is further configured to transmit information to the subscriber unit that indicates a first time period from a set of time periods for the subscriber unit to wait to receive a downlink communication from the wireless base station, wherein the circuitry is further configured to transmit downlink IP data to the subscriber unit in response to the expiration of the first time period; and

the circuitry is further configured to transmit information to the subscriber unit that indicates a second time period from the set of time periods for the subscriber unit to wait to receive a downlink communication from the wireless base station, wherein the circuitry is further configured to transmit downlink IP data to the subscriber unit in response to the expiration of the second time period.

2. The wireless base station of claim 1 wherein the set of time periods is stored in a table.

3. The wireless base station of claim 1 wherein the first time period is selected in response to a type of the IP data.

4. The wireless base station of claim 1 wherein the circuitry includes a scheduler configured to schedule communications with the subscriber unit.

5. The wireless base station of claim 1 wherein the first time period is selected to anticipate arrival of IP data at the wireless base station.

6. The wireless base station of claim 1 wherein the wireless base station is a cellular base station.

7. The wireless base station of claim 1 wherein the IP data includes TCP/IP and UDP/IP data.

8. A wireless subscriber unit comprising:

circuitry configured to communicate internet protocol (IP) data with a base station, wherein the circuitry is further configured to receive information from the base station that indicates a first time period from a set of time periods for the wireless subscriber unit to wait to receive a downlink communication from the base station, wherein the circuitry is further configured to receive downlink IP data from the base station in response to the expiration of the first time period; and

the circuitry is further configured to receive information from the base station that indicates a second time period from the set of time periods for the wireless subscriber unit to wait to receive a downlink communication from the base station, wherein the circuitry is further configured to receive downlink IP data from the base station in response to the expiration of the second time period.

9. The wireless subscriber unit of claim 8 wherein the wireless subscriber unit is a cellular subscriber unit.

10. The wireless subscriber unit of claim 8 wherein the IP data includes TCP/IP and UDP/IP data.
