    摘要: A method for organizing a communication system with automatic handoff. The method includes steps of: (i) sending a message from a first remote unit to a monitoring site during a specific time slot within a frame of time slots, wherein the first remote unit has a unique identification code and the message includes the unique identification code from the first remote unit; (ii) relaying the message including the identification code from the monitoring site to a central authority during a reserved time slot within the frame, the reserved time slot reserved for the relaying step; (iii) transmitting an acknowledgment message from the central authority to the monitoring site, wherein the monitoring site is determined from an updated lookup table of communications links between monitoring sites and remote units, during a time slot reserved for the acknowledgment message; and (iv) retransmitting the acknowledgment message from the monitoring site to the remote unit.
