Abstract
A method includes a first step of receiving a message from a wired network (1) with at least one header station (12). The message is a message type that authorizes a header station or header stations to transmit on a wireless network. A second step of the method is accomplished in response to the received first message, and initiates wireless communications with any mobile communication units (10) that are located within a communication cell served by the at least one header station. In one embodiment the message circulates around a token ring and activates header stations in turn. In another embodiment disjoint groups of header stations are predetermined by graphical techniques, including graph coloring methods. The predetermined group information is maintained by a network controller that thereafter selectively activates the header stations within the different groups.
