Method for seeking a communication system

摘要

In a network of communication systems that comprises a plurality of communication systems, the following discloses a method that allows a communication unit that is seeking a communication system to monitor to verify the integrity of both the transmit communication path and the receive communication path. The first step is for the communication unit to acquire synchronization with the communication system. Having acquired synchronization with the communication system, the communication unit receives transmission parameters of the communication system. Based on the transmission parameters, the communication unit calculates a talk-out gain of the transmit communication path and a talk-in gain of the receive communication path and then calculates a transmit communication path loss and a receive communication path loss. The communication unit will access the communication system when the talk-out gain of the transmit communication path is above the transmit communication path loss and when the talk-in gain of the receive communication path is above the receive communication path loss.
