Abstract

A communication system including PSTN and a mobil communication network (1) where the mobile communication network is connected to a fixed cellular terminal (3) and a cable from said terminal is arranged to a fixed standard telephone (5) which forms a first user interface to a subscriber wishing to make a call or take a call. The fixed cellular terminal (3) includes means for radio communication (2) with at least one hands free headsets (6) which forms a second user interface to said subscriber, which give said subscriber the opportunity to make a call and take a call according to first or second of said interface.

Claims

1. A communication system including PSTN and a mobil communication network (1) where the mobile communication network is connected to a fixed cellular terminal (3) and a cable from said terminal is arranged to a fixed standard telephone (5) which forms a first user interface to a subscriber wishing to make a call or take a call, characterized in that the fixed cellular terminal (3) includes means for radio communication (2) with at least one hands free headsets (6) which forms a second user interface to said subscriber, which give said subscriber the opportunity to make a call and take a call according to first or second of said interface.

2. A communications system according to patent claim 1, characterized in that means for radio communications (2) includes a Bluetooth module which communicate according to the Bluetooth Specification.

3. A communications system according to patent claim 1, characterized in that the headset (6) includes Bluetooth chip which communicate according to the Bluetooth specification.

4. A communications system according to patent claim 2, characterized in that the Bluetooth module includes radio frequency (RF) and baseband circuits, FLASH memory, and a associated software stack.

5. A communications system according to patent claim 3, characterized in that the headset includes a transceiver, microphone and loudspeaker.

6. A communications system according to patent claim 1, characterized in that a fixed subscriber who is connected to a telephone socket (4) have a second user interface which give the subscriber mobility.

8. A communications system according to patent claim 7, characterized in that when he uses the headset for dialling he just say a “

magic word” and

then the enhanced voice recognition in the fixed cellular terminal or in the mobile network makes it possible to “

wake up”

the headset from a standby mode, making it receptive to voice commands.

9. A communications system according to patent claim 1, characterized in that the subscriber can be reached under one number to his two interface.

10.
