Selective call device and method for monitoring at least two communication systems

摘要

A selective call device (106) for monitoring at least two communication systems. The selective call device (106) has a receiver (204) for receiving information from a first communication system (110), a processor (206) for referencing a time slot assignment on the first communication system (110) to a common time base. The processor (206) calculates timing information relating a common time base and a transmitter (222) transmits the timing information to the second communication system (120) informing the second communication system (120) when to transmit information to the selective call device (106) with reference to the common time base.
