For the seamless handover of a connection that is established from a switching station to a terminal equipment via a first base station, to a path via a second base station, a performance feature of the switching station which is also provided for hardwired communication, such as a three-way conferencing circuit, is activated by one base station, this feature prompting a parallel transmission, to both base stations, of the data to be transmitted in the framework of the connection of the mobile terminal equipment. As soon as the data are present in both base stations, the mobile terminal equipment can relocate the data exchange with the switching station from the first base station to the second base station without interruption. The data transmission from the switching station to the first base station is subsequently terminated.

[ I claim as my invention:] [1.]1. A method for seamlessly handing over a connection from mobile terminal equipment, having a radio range, in a communication system having a plurality of base stations and a switching station, comprising the steps of:establishing a transmission connection from said mobile terminal equipment to said switching station via a first base station;monitoring said transmission connection with respect to a predetermined quality criterion;if and when said transmission connection fails to satisfy said predetermined quality criterion, determining whether a second base station exists in said radio range of said mobile terminal equipment to which a different transmission connection can be made which satisfies said predetermined quality criterion, and if so, transmitting a first control signal from one of said first and second base stations to said switching station;upon receipt of said first control signal at said switching station, activating a transmission mode at said switching station selected from the group consisting of transmission modes usable for hardwired transmission, for simultaneously transmitting data from said switching station to a plurality of base stations;using said transmission mode, transmitting data from said switching station to each of said first and second base stations;after both of said first and second base stations are receiving data from said switching station, said mobile terminal equipment terminating transmission to said switching station via said first base station and continuing to transmit to said switching station via said second base station without any interruption in transmission between said mobile telephone equipment and said switching station; andone of said first and second base stations transmitting a second control signal to said switching station and said switching station, upon receipt of said second control signal, terminating data transmission to said first base station.
