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 method for use in a subscriber unit, the method comprising:

receiving first information from a wireless communications base station, wherein the first information indicates a first set of time periods for the subscriber unit to wait to monitor a downlink channel to receive resource allocations from the wireless communications base station;

receiving second information from the wireless communications base station, wherein the second information indicates a second set of time periods for the subscriber unit to wait to monitor the downlink channel to receive resource allocations from the wireless communications base station;

monitoring the downlink channel to receive a resource allocation from the wireless communications base station after expiration of each time period of the first set of time periods; and

on a condition that a resource allocation is not received after expiration of each time period of the first set of time periods, monitoring the downlink channel to receive a resource allocation from the wireless communications base station after expiration of each time period of the second set of time periods.

2. The method of claim 1, wherein the wireless communications base station is a cellular base station.

3. The method of claim 1, wherein the resource allocation is for reception of internet protocol (IP) data.

4. A subscriber unit, the subscriber unit comprising:

a receiver;

an integrated circuit;

the receiver and integrated circuit configured to receive and process first information from a wireless communications base station, wherein the first information indicates a first set of time periods for the subscriber unit to wait to monitor a downlink channel to receive resource allocations from the wireless communications base station;

the receiver and integrated circuit further configured to receive and process second information from the wireless communications base station, wherein the second information indicates a second set of time periods for the subscriber unit to wait to monitor the downlink channel to receive resource allocations from the wireless communications base station;

the receiver further configured to monitor the downlink channel to receive a resource allocation from the wireless communications base station after expiration of each time period of the first set time periods; and

on a condition that a resource allocation is not received after expiration of each time period of the first set of time periods, the receiver further configured to monitor the downlink channel to receive a resource allocation from the wireless communications base station after expiration of each time period of the second set of time periods.

5. The subscriber unit of claim 4, wherein the wireless communications base station is a cellular base station.

6. The subscriber unit of claim 4, wherein the resource allocation is for reception of internet protocol (IP) data.
