Title: Terminating extension groups controlled by wireless terminals

Abstract: A wireless terminal dynamically positions itself into a terminating ring group based on the location of the wireless terminal. Similarly, a wireless terminal dynamically removes itself from a terminating ring group on the basis of the location of the wireless terminal. A wireless terminal can be excluded from joining a terminating ring group in a specific location. The wireless terminal positions itself into the terminating ring group by communicating information with other wireless terminals already in the terminating ring group. This communication is controlled by a controlling wireless terminal with which the wireless terminal first communicates upon entering the location. The wireless terminal determines its position by communication with a fixed unit assigned to the location of terminating ring group. Upon determining that it is leaving the location, the wireless terminal transmits a message to controlling wireless terminal to inform it of this fact. In turn, the controlling wireless terminal transmits messages to the other wireless terminals to inform them of the departure of the wireless terminal.
