Handover method for mobile radio system

A method of communication in a cellular mobile radio system having a plurality of base station transmitters and mobile stations comprising the steps of:

• transmitting, from a first base station transmitter for a first cell, radio signals digitally modulated with message information to a mobile station;
• while transmitting the radio signals from the first base station transmitter to the mobile station, beginning to transmit, from a second base station transmitter for a second cell to the mobile station, radio signals digitally modulated with substantially the same message information;
• and
• terminating the transmission from the first base station transmitter to the mobile station while continuing to transmit from the second base station transmitter.

• transmitting, from a second base station transmitter to the mobile station, radio signals digitally modulated with substantially the same message information to the mobile station;
• and
• before terminating the transmission from the first or second base station transmitter of the digitally modulated radio signals to the mobile station, beginning to transmit from a third base station transmitter radio signals digitally modulated with substantially the same message information as the signals from the first and second base station transmitters.
