Abstract

A method providing automatic control of call diversion from a first terminal (TEG), which is coupled to a switching device (V), to any desired second terminal (MEG). The call diversion process is controlled as a function of the position of a mobile terminal (MEG) relative to a base station (BS1) which is coupled to the switching device (V). A measure for the relative position of the mobile terminal (MEG) is in this case determined on the basis of radio signals which are transmitted between the base station (BS1) and the mobile terminal (MEG).

Claims

1. A method for controlling call diversion, which comprises:

coupling a first terminal, for which call diversion is to be activated, to a switching device;

determining a measure indicating a position of a mobile terminal relative to at least one base station using radio signals that are transmitted between the mobile terminal and the at least one base station; and

using a switching device to control the call diversion as a function of the determined measure.

2. The method according to

claim 1

, wherein the measure indicating the position of the mobile terminal is determined as a distance measure indicating a distance between the mobile terminal and the at least one base station.

3. The method according to

claim 1

, which comprises using a received field strength of the radio signals to determine the measure indicating the position of the mobile terminal.

4. The method according to

claim 1

, which comprises evaluating radio signals which are transmitted between the mobile terminal and a plurality of base stations to determine the measure indicating the position of the mobile terminal.

5. The method according to

claim 4

, which comprises:

determining a distance measure indicating a distance between the mobile terminal and the first terminal; and

using the distance measure as the measure indicating the position of the mobile terminal.

6. The method according to

claim 1

, which comprises determining, in the at least one base station, the measure indicating the position of the mobile terminal.

7. The method according to

claim 1

, which comprises:

determining, with the mobile terminal, the measure indicating the position of the mobile terminal; and

transmitting the measure from the mobile terminal to a base station.

8. The method according to

claim 1

which comprises:

determining, in the at least one base station, the measure indicating the position of the mobile terminal;

if the measure indicating the position of the mobile terminal goes outside a predetermined value frame, transmitting, with the at least one base station, a message to the switching device; and

subsequently

in a predetermined manner, performing the step of controlling the call diversion using the switching device.

9. The method according to

claim 1

, which comprises:

determining, in the at least one base station, the measure indicating the position of the mobile terminal;

transmitting, from a base station to the switching device, the measure indicating the position of the mobile terminal; and

if the transmitted measure goes outside a predetermined value frame, then in a predetermined manner performing the step of controlling the call diversion using the switching device.

10. The method according to

claim 1

, which comprises:

determining, with the mobile terminal, the measure indicating the position of the mobile terminal;

if the measure goes outside a predetermined value frame, transmitting a message to a base station; and

initiating, with the base station, the control of the call diversion.

11. The method according to

claim 10

wherein:

the transmitted message includes control information that identifies the first terminal and a second terminal;

the control information is for controlling the call diversion; and

the call diversion involves the first terminal and the second terminal.

12. The method according to

claim 10

, wherein the predetermined value frame is governed by a range of a wire-free link between the mobile terminal and the at least one base station.

13. The method according to

claim 10

, which comprises predetermining various value frames such that a value-frame-specific call diversion process is initiated when the measure indicating the position of the mobile terminal goes outside each respective one of the value frames.

14. The method according to

claim 10

which comprises predetermining a terminal-specific value frame for a plurality of mobile terminals.

15. A method for controlling call diversion, which comprises:

coupling a first terminal, for which call diversion is to be activated, to a switching device;

registering, with a base station that is coupled to the switching device, whether a mobile terminal other than the first terminal can be accessed for connection requests; and

controlling the call diversion process, with the switching device, as a function of the registration.

16. The method according to

claim 15

, wherein if there are a plurality of base stations within radio range of the mobile terminal, the mobile terminal uses a predetermined prioritization list to determine which one of the plurality of base stations is preferable for the mobile terminal to register with, in order to control the call diversion process.

17. The method according to

claim 15

which comprises controlling a terminal-specific call diversion process for each of a plurality of mobile terminals.
