Abstract:
PURPOSE: To provide a communication system with which transfer to an optimum substitutive first-order station can be speedily achieved without exchanging communication when degrading the quality of signal to be received by a second- order station to move in a mobile radio system. CONSTITUTION: In the mobile radio system for carrying one group call at least, the respective 1st-order stations accompanied with calls transmit the identity of another base station fitted in the calls themselves and accompanied with these calls. In a TDMA signal, this identity is transmitted during the term of ramp slot R or associated control slot AC in a control slot C of frame F dedicated to a multiframe M. Similarly, it is appliable to an FDMA system.
