ABSTRACT:
A method and arrangement for transfer between a cordless telecommunication system, preferably DECT, and a cellular mobile telecommunication system, preferably GSM. The cordless telecommunication system includes of a number of cells within a relatively small area, while the mobile telecommunication system includes of a number of cells within a relatively larger area which completely or partly overlaps the area of the cordless system. The system comprises at least one portable terminal capable of communicating with both the cordless and cellular communication systems. Accordingly a transfer zone is fixed by the cordless system and the terminal is monitored with regard to it identity and position so that transfer parameters can be transmitted to the terminal when it is located in the transfer zone. The transfer is prepared by setting up a three-party connection between the terminal and the telecommunication system and between the terminal and the mobile telecommunication system. The terminal disconnects the connection to the cordless telecommunication system and a transfer to the mobile system takes place. The method and arrangement reduce the transfer time between the different systems by transmitting transfer parameters to the portable terminal and setting up the preparatory three-party connection.
