A method for the implementation of a connection handover initiated by a cordless terminal equipment in Detect systems with modified standard: After the signaling of the call setup request signal 'Connection Hand Over Request', the mobile part also immediately transmits the user data in the newly captured channel. After reception of the 'Connection HO Request' forwarded by the newly selected base station, reception in the switching node can therefore be immediately switched thereto (without a gap in the user data transmission). In the transmission direction, the switching equipment can transmit in parallel via both base stations until, for example, an acknowledgment is received from the new base station with respect to the error-free signal output of 'Bearer Confirm', or until the mobile part clears down the previous connection.
