A central controller (101) in the TDM wireless communication system (100) transmits a data channel update message (600), including an allocation profile (603) and an update interval (605) to a second group of communication units (107-109). The allocation profile indicates time slots used to form a data channel and the update interval indicates a period of time until transmission of the next data channel update message. The data channel update message, transmitted via the data channel, is sent in response to a request from a first group of communication units (104-106) or upon expiration of a period of time based on a previous update interval. Repetition of this process allows time slots to be dynamically allocated in response to changing system requirements, while minimizing use of the data channel for data channel update messages.

In a TDM wireless communication system comprising a plurality of communication units and a central controller that allocates a plurality of time slots among the plurality of communication units, wherein the plurality of communication units are logically divided into a first group and a second group, and wherein a data channel allocated to the second group comprises a portion of the plurality of time slots, a method for the central controller to dynamically control the portion of the plurality of time slots, the method comprising steps of: a) receiving from a communication unit of the first group a request for at least one time slot of the plurality of time slots; b) transmitting, via the data channel, responsive to the request, a data channel update message to the second group, wherein the data channel update message comprises an allocation profile that indicates the portion of the plurality of time slots; and c) allocating the at least one time slot to the communication unit of the first group once the data channel update message has been transmitted.
