ABSTRACT:
A handover technique in a cellular radio communication system (100) for handing over a radio (102) from a first channel in a first cell to a second channel in a second cell, the technique comprising generating a fill-in message extrapolated from a message of the radio on the first channel and communicating the fill-in message when the radio has ceased communicating on the first channel; and terminating the fill-in message when the radio begins communicating on the second channel, thereby reducing handover disruption. The messages may be digitized audio messages. A timer (110, 118) may be employed to allow the fill-in message to terminate at substantially the same time as the radio begins communicating on the second channel. Alternatively, the fill-in message may be directly terminated (FIG. 2) in response to the radio beginning to communicate on the second channel. If the messages are data messages, no fill-in message is generated and the handover is completed directly (FIG. 2) in response to the radio beginning to communicate on the second channel.
