Abstract

An enhanced call waiting (ECW) feature is provided by a switch serving a called subscriber who, while still on a first telephone call, receives a subsequent telephone call. According to ECW, the switch provides service so that the called party may select from processing treatments for the second call which, in addition to the conventional processing of a) placing the first telephone call on hold and answering the second telephone call request, or b) simply declining the subsequent telephone call request, include treatments such as: 1) declining acceptance of the subsequent telephone call request but signaling the subsequent telephone call originator, via a message, to call again at a predetermined time or at the end of a specified period of time; 2) declining acceptance of the subsequent telephone call request and signaling the subsequent telephone call originator, via a message, that the called subscriber will return the call at a predetermined time or at the end of a specified period of time; 3) bridging the subsequent telephone call originator with the first telephone call to establish a conference; 4) directing, via a message, that the telephone call be transferred to another telephone number, e.g., a secretary or voice messaging system, that is specified as part of the message; or 5) disabling call waiting while the called subscriber remains on the first call, (i) for this particular caller, (ii) for all callers except those listed on a so-called "exception" list, or (iii) for all callers.

Claims

1. Apparatus for processing telephone calls to a called tip and ring telephone during a first telephone call, the apparatus comprising:

means for detecting a second telephone call destined to said called tip and ring telephone while said tip and ring telephone remains on said first telephone call; and

means for receiving a message from said called tip and ring telephone while said tip and ring telephone remains on said first telephone call, said message indicating that said second telephone call is to be transferred;

wherein said message is received prior to said second telephone call being answered.

2. The invention as defined in claim 1 further including means for supplying information associated with origination of said first telephone call to said tip and ring telephone.

3. The invention as defined in claim 1 wherein said message indicates that said second telephone call is to be transferred to a predefined default destination.

4. The invention as defined in claim 1 wherein said message explicitly specifies a destination to which said second telephone call is to be transferred.

5. The invention as defined in claim 1 wherein a destination to which said second telephone call is to be transferred is derived by translation of information received in said message.

6. The invention as defined in claim 1 further comprising means for translating information received in said message to develop a destination to which said second telephone call is to be transferred.

7. The invention as defined in claim 1 wherein said first telephone call originates from a first calling telephone, and wherein said message is received without disconnecting said first calling telephone and said called tip and ring telephone.

8. The invention as defined in claim 1 wherein said first telephone call originates from a first calling telephone line, and wherein said message is received without disconnecting said first calling telephone and said called tip and ring telephone.

9. The invention as defined in claim 1 further comprising means for rerouting said second telephone call to a destination other than said called telephone.

10. The invention as defined in claim 1 further comprising means for announcing to an originator of said second telephone call that said second telephone call is being rerouted prior to said second telephone call being rerouted, and wherein said announcement includes an indication of a destination to which said second telephone call is being transferred.

11. The invention as defined in claim 1 further comprising means for announcing to an originator of said second telephone call that said second telephone call is being rerouted prior to said second telephone call being rerouted, and wherein said announcement includes an indication of a destination to which said second telephone call is being rerouted to.

12. Apparatus for processing telephone calls to a called tip and ring telephone during a first telephone call, the apparatus comprising:

means for detecting a second telephone call destined to said called tip and ring telephone during continued existence of said first telephone call to said called tip and ring telephone; and

means for receiving a message from said called tip and ring telephone while said tip and ring telephone remains on said first telephone call, said message indicating that said second telephone call is to be transferred;

wherein said message is received without said second telephone call being routed to said called telephone.

13. The invention as defined in claim 12 further comprising means for rerouting said second telephone call to a destination other than said called telephone.

14. The invention as defined in claim 12 further comprising means for announcing to an originator of said second telephone call that said second telephone call is being transferred.

15. The invention as defined in claim 12 further comprising means for announcing to an originator of said second telephone call that said second telephone call is being transferred, and wherein said announcement includes an indication of a destination to which said second telephone call is being transferred.

16. Apparatus for processing telephone calls to a called tip and ring telephone during a first telephone call, the apparatus comprising:

means for detecting a second telephone call destined to said called tip and ring telephone during continued existence of said first telephone call at said tip and ring telephone;

means for receiving a message from said called tip and ring telephone while said tip and ring telephone remains on said first telephone call, said message indicating that said second telephone call is to be transferred; and

means for transferring said second telephone call to a destination other than said called telephone without said second telephone call being answered prior to its being transferred.

17. A method for use in a switch for processing telephone calls to a called tip and ring telephone during a first telephone call, the apparatus comprising:

detecting a second telephone call destined to said called tip and ring telephone during continued existence of said first telephone call at said called tip and ring telephone;

receiving a message from said called tip and ring telephone during continued existence of said first telephone call at said called tip and ring telephone, said message indicating that said second telephone call is to be transferred; and

transferring said second telephone call to a destination other than said called telephone without said second telephone call being answered prior to its being transferred.

18. The invention as defined in claim 17 wherein said message indicates that said second telephone call is to be transferred to a predefined default destination.

19. The invention as defined in claim 17 wherein said message explicitly specifies a destination to which said second telephone call is to be transferred.

20. The invention as defined in claim 17 further including the step of translating information received in said message to a destination to which said second telephone call is to be transferred.

21. The invention as defined in claim 17 further including the step of announcing to an originator of said second telephone call that said second telephone call is being transferred.

22. The invention as defined in claim 17 further including the step of announcing to an originator of said second telephone call that said second telephone call is being transferred, and wherein said announcement includes an indication of a destination to which said second telephone call is being transferred.

23. A method for use in a switch for processing telephone calls to a called tip and ring telephone during a first telephone call, the apparatus comprising:

detecting a second telephone call destined to said called tip and ring telephone during continued existence of said first telephone call; and

receiving a message from said called tip and ring telephone indicating that said second telephone call is to be transferred while said telephone remains on said first call;

wherein said message is received prior to said second telephone call being answered.
