Abstract
Abstract A multi-mode radio telephone 22 operative in at least two radio systems, such as cordless and cellular, has sensing means 29 so that when the user enters the area 24 of operation of the cordless system the handset 22 automatically transmits a signal to the cellular system to initiate a call forwarding facility 11, according to which calls for the radio telephone 22 on the cellular system are automatically forwarded to the cordless system. Hence, the invention prevents loss of calls on the cellular system sent to the handset whilst in the cordless system.
