Title: Radio communication system using frequency hopping system radio communication equipment and its control method
Inventor: NAGO HIDETADA
IPC: H04B1/713
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To avoid interference on communication between radio communication equipments by making communication through timewise deviated hopping patterns with each other based on received information. SOLUTION: A master set 1 monitors a communication status of all terminal equipments 3A-3F in a system. Then the monitor results such as whether or not communication is made, a hopping pattern in use during the communication, which correction circuit channel in a frame is to be designated are stored. In this case, since a hopping pattern used for the communication between the terminal equipments and a hopping pattern used for the communication between the terminal equipments 3A-3F and the master set 1 do not use the same frequency channel simultaneously, when an extension connection request comes from the terminal equipments 3A-3F, the master set 1 informs it how much the hopping pattern used for the communication between the terminal equipments is deviated timewise from the hopping pattern used for the communication between the terminal equipments 3A-3F and the master set 1.
