In a TDM wireless communication system (100), a central controller (104) monitors the transfer of a message (108) in order to determine a system grade of service. Based on the system grade of service, the central controller dynamically allocates a lesser or greater number of wireless communication resources (105). Alternatively, a communication unit (101) can directly request additional wireless communication resources. |

DETAILED DESCRIPTION We claim: 1.
In a TDM wireless communication system that includes a plurality of communication units, a plurality of wireless communication resources, and a central controller that allocates the plurality of wireless communication resources among the plurality of communication units, a method for dynamically allocating the plurality of wireless communication resources, the method comprising the steps of: a) requesting, by a communication unit of the plurality of communication units, a first number of wireless communication resources of the plurality of wireless communication resources for transmission of a message; b) when the first number of wireless communication resources are available, allocating, by the central controller, the first number of wireless communication resources to the communication unit; c) responsive to allocation of the first number of wireless communication resources, transmitting, by the communication unit, portions of the message via the first number of wireless communication resources; d) monitoring, by the central controller, transmission of the portions of the message to determine a system grade of service; and e) allocating, by the central controller, a second number of wireless communication resources to the communication unit based on the system grade of service.
2.
The method of claim 1, step (b) further comprising the step of allocating the first number of wireless communication resources, wherein the first number of wireless communication resources comprise a first number of time slots on a radio frequency carrier.
3.
The method of claim 2, step (e) further comprising the step of allocating the second number of wireless communication resources, wherein the second number of wireless communication resources comprise a second number of time slots on the radio frequency carrier.
4.
The method of claim 1, step (d) further comprising the step of monitoring transmission of the portions of the message to determine the system grade of service, wherein the system grade of service is based, at least in part, on a predicted completion time for the message
