发明名称 Trunking system access method
摘要 In a communication system, the following describes a method for the communication system to more efficiently process control information when the control channel is temporarily used as a voice channel. When a communication unit has control information to transmit to the communication resource allocator, it determines whether the monitored voice channel is busy. When the monitored voice channel is not busy, the communication unit transmits the control information to the communication resource allocator on the monitored voice channel. Regardless of whether the monitored voice channel is busy or not, the communication resource allocator transmits recommended channel parameters on the monitored channel wherein the recommended channel parameters comprises at least one recommended channel. When the monitored voice channel is busy, the communication unit decodes the recommended channel parameters to ascertain the at least one recommended channel. Having done this, the communication unit determines whether the at least one recommended channel is usable, and when the recommended channel is usable, the communication unit transmits its control information on that channel to the communication resource allocator.
