Radio telephone system with one-to-many dispatch system |
摘要 |
A one-to-many dispatch method for use in a TDMA or other wireless telephone system. The one-to-many dispatch call is placed by sending a Request message 204 from a Personal Station PS 112 to a Control Center Station (CS) 120 which assigns a channel with an Assignment message 208. The PS 112 sends a call setup message over the control channel resulting in a channel assign message 242 being broadcast repeatedly. Call connect messages over the Assigned Channel AC 244 are also repeated from the CS 120 to indicate the open connection. A hang timer is started when the PS 112 ceases transmission of voice and the connection is torn down upon expiry of the hang timer unless another PS transmits a call setup message 234 on the Assigned Channel AC before the expiry of the hang timer.
