ABSTRACT:
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.
