Abstract

Telecommunications terminals, and a method for controlling call diversion between such telecommunications terminals, wherein it is guaranteed that a call diversion between the terminals takes place only if it is required, without a user having to spend time on it. Specifically, a stationary telecommunications terminal initiates call forwarding from itself to a mobile terminal if the presence of a recognition signal of the mobile terminal is not detected, and cancels the call forwarding if the presence of the recognition signal following an interruption is again detected.

Claims

1. A stationary telecommunications terminal (1) for connection to a switching node point (5) of a fixed telecommunications network, whereby it comprises a detector (2, 3) to detect the presence of an allocated mobile telecommunications terminal (4) in its vicinity, and whereby the detector comprises a radio receiver (3), an infrared or ultrasonic receiver, with which a characteristic recognition signal emitted by the mobile telecommunications terminal (4) can be detected, characterized in that the stationary telecommunications terminal (1) is set up in such a way that it initiates call forwarding from itself to the mobile terminal (4) if the detector (2, 3) does not detect the presence of the recognition signal of the mobile telecommunications terminal (4), and in that it cancels the call forwarding if the detector (2, 3) again detects the presence of the recognition signal of the allocated mobile telecommunications terminal (4) following an interruption.

2. The stationary telecommunications terminal as claimed in claim 1, characterized in that the detector (2, 3) is set up to identify the recognition signal of the allocated terminal (4) from a plurality of recognition signals emitted by different mobile terminals.

3. The stationary telecommunications terminal as claimed in one of the preceding claims, characterized in that the detector (2, 3) is set up to process signals according to the Bluetooth standard.

4. The stationary telecommunications terminal as claimed in one of the preceding claims, characterized in that it comprises a fixed-network telephone (1) or DECT telephone.

5. The stationary telecommunications terminal as claimed in one of the preceding claims, characterized in that the telecommunications terminal (4) has a first range to receive and transmit voice or data signals and in that it is set up to emit a recognition signal characteristic of the terminal with a second range which is shorter than the first range.

6. The stationary telecommunications terminal as claimed in claim 5, characterized in that the second range is not more than 30 m.

7. The stationary telecommunications terminal as claimed in claim 5 or 6, characterized in that the mobile telecommunications terminal (4) has a radio, infrared or ultrasonic transmitter to emit the recognition signal.

8. The stationary telecommunications terminal as claimed in one of claims 5 to 7, characterized in that the mobile telecommunications terminal (4) emits the recognition signal at a transmit interval of several seconds to several minutes.

9. The stationary telecommunications terminal as claimed in one of claims 5 to 8, characterized in that the mobile telecommunications terminal (4) emits the recognition signal in each case in response to the reception of a prompt signal.

10. The stationary telecommunications terminal as claimed in one of claims 5 to 9, characterized in that the recognition signal is a signal according to the Bluetooth standard.

11. A method for controlling call diversion from a stationary (1, 2, 3) to a mobile telecommunications terminal (4), whereby the presence of the mobile terminal (4) in the vicinity of the stationary terminal (1, 2, 3) is checked with the aid of a detector (2, 3), and whereby the detector (2, 3) comprises a radio receiver (3), an infrared or ultrasonic receiver, with which a characteristic recognition signal emitted by the mobile telecommunications terminal (4) is detected, characterized in that a call diversion is set up from the stationary to the mobile terminal if the check reveals that the mobile terminal (4) has left the vicinity of the stationary terminal (1, 2, 3), and in that the call forwarding is cancelled if a further check reveals that the mobile terminal (4) is again located in the vicinity of the stationary terminal (1, 2, 3).

12. The method as claimed in claim 11, characterized in that the stationary terminal (1, 2, 3) decides during the check whether or not the mobile terminal (4) is located in the vicinity, according to whether or not it receives a recognition signal emitted by the mobile terminal (4).

13. The method as claimed in claim 11 or 12, characterized in that the mobile terminal (4) periodically emits the recognition signal.

14. The method as claimed in claim 12 or 13, characterized in that the mobile terminal (4) emits the recognition signal on receiving a prompt signal from the mobile terminal.
