Abstract

A method and terminal for use in a telecommunications infrastructure which allows a call directed to a particular subscriber to be taken selectively at one of at least two separate terminals, has the subscriber identify himself to at least one of the terminals through a subscriber identity card, or the like, which can be detected within a limited space associated with the environment of one of the terminals. The subscriber 10 registers all his terminals 11, 12 (home, office, car, hand-held) with a service operator 3. Each terminal which detects the subscriber'"'"'s proximity in the associated space or environment signals this to the service operator 3. Calls directed to the subscriber are routed to the service operator and from the latter to the terminal which has signaled last, or which is selected according to an algorithm, depending on the sensed signal. In this way, an automatic changeover is accomplished without restricting the subscriber'"'"'s freedom.

Claims

1. A method of selecting one of at least two telephone terminals (11, 12) assigned or assignable to a same subscriber,

comprising the steps of

generating, in at least a stationary one of said two telephone terminals, a field which causes a unit carried by said subscriber to transmit subscriber identification signals,

detecting, in at least one (11) of said telephone terminals, said subscriber identification signals from said carried unit, and upon detection of such subscriber identification, routing any incoming telephone call intended for said subscriber to that telephone terminal where such detection most recently occurred.

2. A method as claimed in claim 1, wherein

the at least one telephone terminal (11) reports a detection of a subscriber identification signal to a center (3),

calls directed to the same subscriber (10) are reported to the center (3), and

based on reports received, the center (3) selects one of said at least two telephone terminals (11, 12) and causes the calls to be routed to said telephone terminal.

8. The method according to claim 1, wherein at least one (12) of said telephone terminals (11, 12) is a hand-held telephone, and wherein, if a predetermined period of time has elapsed without detection of such subscriber identification, any incoming telephone call is routed by default to said hand-held telephone (12).

9. The method of claim 1, wherein said detecting step comprises

detecting electromagnetic signals emanating from a unit (18) carried on the person of the subscriber.

10. The method of claim 9, wherein said detecting step comprises

detecting inductive signals emanating from a unit (18) carried on the person of the subscriber.

11. The method of claim 1, wherein said detecting step comprises

detecting sonic signals emanating from a unit (18) carried on the person of the subscriber.

12. The method of claim 1, wherein said detecting step comprises detecting an identifying personal characteristic of the subscriber.

3. A telecommunications terminal (11), having

a sensor (16) for receiving and detecting subscriber identification signals from a device carried on the person of a subscriber to personally identify the subscriber and detect presence of the subscriber in the vicinity of said terminal (11), and

a switching device (20), coupled to an output of said sensor, for initiating an assignment of the telecommunications terminal (11) to said subscriber, for routing of calls to said terminal, upon receipt of a subscriber identification signal.

4. A telecommunications terminal (11) as claimed in claim 3, characterized in that

it has a transmitter (XMTR) for generating a field, due to which a unit (18) carried by a subscriber (10) is caused to transmit subscriber identification signals.

5. A telecommunications terminal (11) as claimed in claim 3, characterized in that

the switching device includes a means for transmitting a message via a communications network (2) to a center (3).

6. Method of selecting one of at least two communications terminals (11, 12) assignable to a same subscriber, comprising the steps of:

(a) sensing (34) for a subscriber identification (ID) signal in an environment of a first one (11) of said communications terminals and determining (36);

(i) said ID signal is sensed and executing a step (b);

or

(ii) said ID signal is not sensed and executing a step (c);

(b) assigning (38) said first one of the communications terminals to said same subscriber and re-executing step (a); and

(c) assigning (40) a second one (12) of said communications terminals to said same subscriber and re-executing step (a).

7. Method of selecting one of at least two communications terminals (11, 12) assignable to a same subscriber, comprising the steps of:

(a) sensing (10a) for a subscriber identification (ID) signal in an environment of a first one of said communications terminals and determining (12a);

(i) said ID signal is sensed and executing a step (b);

or

(ii) said ID signal is not sensed and executing a step (d);

(b) assigning (26) said first one of the communications terminals to said same subscriber;

(c) sensing (28) for said subscriber ID signal in said environment of said first one of said communications terminals and determining (29);

(i) said ID signal is sensed and re-executing step (c);

or

(ii) said ID signal is not sensed and executing said step (d);

(d) assigning (14) a second one of said communications terminals to said same subscriber; and

(e) sensing (15a) for said subscriber ID signal in said environment of said first one of said communications terminals and determining (15b);

(i) said ID signal is sensed and executing step (b);

or

(ii) said ID signal is not sensed and re-executing said step (e).

13. A method of selecting one of at least two telephone terminals (11, 12) assigned or assignable to a particular subscriber,

comprising the steps of

detecting, in at least one (11) of said telephone terminals, the voice of the subscriber as an identifying personal characteristic, and

upon such identification of the subscriber, routing any incoming telephone call intended for said subscriber to that telephone terminal where such detection most recently occurred.

14. A method of selecting one of at least two telephone terminals (11, 12) assigned or assignable to a particular subscriber,

comprising the steps of

detecting, in at least one (11) of said telephone terminals, the appearance of the subscriber as an identifying personal characteristic, and

upon such identification of the subscriber, routing any incoming telephone call intended for said subscriber to that telephone terminal where such detection most recently occurred.
