摘要

To transfer the handling of an active connection being handled by a first switching exchange connected to the exchange equipped for fixed telecommunication to a base station associated with another switching exchange, a connection is made between the first and the other switching exchange and a connection is made between said other switching exchange and the base station associated therewith, which base station reserves a radio channel for the mobile terminal, after which the communication with the mobile terminal is taken over by said base station; a connection is also made between the exchange equipped for fixed telecommunication and the other switching exchange and, after the connection to the mobile terminal has been taken over by the base station, the entire handling of the connection is taken over by the other switching exchange and the connection between the two switching exchanges, and between the first switching exchange, and the exchange equipped for fixed telecommunication, is disconnected.
