Abstract
Abstract A telephone subscriber who wishes to forward calls placed to that subscriber from a selected set of calling parties identifies the current destination number to a service adjunct. The service adjunct, in turn, transmits the destination number to the intelligent terminals of preselected parties while those intelligent terminals are in an inactive (i.e. on-hook) mode, for storage in a local memory contained in those terminals. Thereafter, when the usual number of the telephone subscriber is "dialed" (e.g., entered on the keypad) at any one of the intelligent terminals, the stored destination number is retrieved and output to the telecommunications network in place of the usual number. The actual destination number is also displayed to the calling party who then has the option to let the call complete or disconnect to stop the call.

Claim 2
Independent Claim
98 words
A method for transferring information to intelligent terminals, for use in forwarding calls, comprising the steps of: storing information identifying (a) a personal number of a subscriber, (b) a forwarding number associated with said personal number, and (c) said intelligent terminals of selected calling parties, in a central processor, transmitting said personal number and said forwarding number to said intelligent terminals of said selected calling parties while said intelligent terminals of said selected calling parties are in an on-hook mode, and recording said personal number and said forwarding number in said intelligent terminals of said selected calling parties.
Claim 3
Dependent Claim
48 words
The method of claim 1, further comprising the step of: when said personal number of said subscriber is dialed at a given one of said intelligent terminals, retrieving said forwarding number recorded thereat, and outputting said forwarding number to a telecommunications network in place of said personal number.
Claim 4
Dependent Claim
30 words
The method of claim 1 wherein said transmitting step includes transmitting said personal number and said forwarding number to said intelligent terminals via ISDN connections using X.25 packet data communications.
Claim 5
Dependent Claim
33 words
The method of claim 1 wherein said transmitting step includes transmitting said personal number and said forwarding number to said intelligent terminals via network SS7 facilities, which are mapped into Q.931 signaling messages.
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein said transmitting step includes transmitting said personal number and said forwarding number to said intelligent terminals using analog signaling.
Claim 7
Dependent Claim
15 words
The method of claim 1 wherein said central processor is located in a telecommunications network.
Claim 8
Dependent Claim
20 words
The method of claim 1 wherein said central processor is connected to a telecommunications network via an ISDN BRI connection.
Claim 9
Dependent Claim
50 words
The method in claim 1 wherein said intelligent terminals are wireless terminals and wherein said personal number and said forwarding number are transmitted to said wireless terminals of said selected calling parties via a control channel while said wireless terminals of said selected calling parties are in an on-hook mode.
Claim 10
Independent Claim
109 words
A method for processing calls in an intelligent station so that calls to preselected personal numbers are forwarded to associated forwarding numbers, said method comprising the steps of: receiving, while said intelligent station is in an on-hook condition, information from a services adjunct identifying (a) a dialed personal number, and (b) an associated forwarding number to be used in place of the dialed personal number; storing said information in a memory in said intelligent station; determining if the dialed personal number has a stored associated forwarding number; if a stored associated forwarding number exists, completing a call using said associated forwarding number in place of said dialed personal number.
Claim 11
Independent Claim
109 words
A method for processing calls in an intelligent station so that calls to preselected personal numbers are forwarded to associated forwarding numbers, said method comprising the steps of: receiving, while said intelligent station is in an on-hook condition, information from a services adjunct identifying (a) a dialed personal number, and (b) an associated forwarding number to be used in place of the dialed personal number; storing said information in a memory in said intelligent station; determining if the dialed personal number has a stored associated forwarding number; if a stored associated forwarding number exists, completing a call using said associated forwarding number in place of said dialed personal number.
Claim 12
Dependent Claim
20 words
The method defined in claim 9 further including the step of displaying said forwarding number prior to completing said call.
Claim 13
Dependent Claim
89 words
Apparatus for transferring information to intelligent terminals, comprising: a database for storing information identifying (a) a personal number of a subscriber, (b) a forwarding number associated with said personal number, and (c) said intelligent terminals of selected calling parties, and means for transmitting said personal number and said associated forwarding number to said intelligent terminals of said selected calling parties while said intelligent terminals are in an on-hook mode; and means for recording said personal number and said forwarding number at said intelligent terminals of said selected calling parties.
