  • Patent number: 6263203
    Abstract: 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.
