Abstract
Abstract The number of times that a subscriber is forced to add an area code to his or her dialing sequence is substantially reduced by allowing calling parties to dial without including the area code, by analyzing the called party number relative to the calling party, and by resolving ambiguities in the called number based on that analysis. The analysis includes, but is not limited to, taking account of the calling pattern of the calling subscriber, and taking account of the distance between the calling and the called parties.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
124 words
A method for connecting a calling party to a called party via a telecommunication network, comprising the steps of: receiving a sequence of digits; determining whether the sequence of digits contains area code digits; only when the sequence of digits does not include area code digits, analyzing the received digits relative to the calling party to form therefrom a telephone number specification, wherein said analyzing identifies uncertainty stemming from the analysis of the received digits relative to the calling party and resolves said uncertainty, when it occurs, by appending an area code, or refraining from appending an area code; and initiating a process, responsive to said step of analyzing, for connecting the calling party to the called party based on said telephone number specification.
Claim 2
Independent Claim
124 words
A method for connecting a calling party to a called party via a telecommunication network, comprising the steps of: receiving a sequence of digits; determining whether the sequence of digits contains area code digits; only when the sequence of digits does not include area code digits, analyzing the received digits relative to the calling party to form therefrom a telephone number specification, wherein said analyzing identifies uncertainty stemming from the analysis of the received digits relative to the calling party and resolves said uncertainty, when it occurs, by appending an area code, or refraining from appending an area code; and initiating a process, responsive to said step of analyzing, for connecting the calling party to the called party based on said telephone number specification.
Claim 3
Dependent Claim
13 words
The method of claim 1 further comprising a step of generating billing information.
Claim 4
Dependent Claim
29 words
The method of claim 1 wherein said analysis determines a telephone number specification that has the highest likelihood of being a telephone number that corresponds to the called party.
Claim 5
Dependent Claim
29 words
The method of claim 3 wherein said telephone number specification is derived by considering a database that associates the calling party with a plurality of potential different called parties.
Claim 6
Dependent Claim
18 words
The method of claim 4 wherein said database comprises information about previous calls made by the calling party.
Claim 7
Dependent Claim
17 words
The method of claim 4 wherein said database comprises information inserted on behalf of the calling party.
Claim 8
Dependent Claim
26 words
The method of claim 4 wherein said database comprises information regarding parties called often by the calling party and parties called recently by the calling party.
Claim 9
Dependent Claim
45 words
The method of claim 7 further comprising a step of generating billing information that is sensitive to whether the called party is found among the information regarding parties called often by the calling party or among information regarding parties called recently by the calling party.
Claim 10
Dependent Claim
35 words
The method of claim 3 wherein said telephone specification is derived by considering a geographical distance between the calling party and parties that are assigned said sequence of digits, but belong to different area codes.
Claim 11
Dependent Claim
48 words
The method of claim 3 wherein said telephone number specification is derived by considering a database that associates the calling party with potential different parties, and a geographical distance between the calling party and parties that are assigned said sequence of digits, but belong to different area codes.
Claim 12
Dependent Claim
25 words
The method of claim 10 where the database is located in a switch controlled by a service provider to which the calling party is connected.
Claim 13
Dependent Claim
15 words
The method of claim 10 where the database is located in a central network database.
Claim 14
Dependent Claim
13 words
The method of claim 10 where the database is located in a PBX.
Claim 15
Dependent Claim
41 words
The method of claim 1 further including a step of announcing to the calling party said telephone number specification that will be employed in establishing a connection of the calling party to the party with whom the connection will be established.
Claim 16
Dependent Claim
27 words
The method of claim 1 further comprising a step of announcing the name of the party with whom a connection with the calling party will be established.
Claim 17
Independent Claim
38 words
The method of claims 14 or 15 wherein the step of announcing includes an invitation to the calling party to direct that a connection not be established to the telephone number specification identified by the step of analyzing.
Claim 18
Dependent Claim
51 words
The method of claim 1 wherein the received sequence of digits includes the starting digits of a number that is normally required in the telecommunication network for requesting connection to a called party within the calling party's area code, but less than all of the digits that are normally so required.
Claim 19
Dependent Claim
19 words
The method of claim 17 wherein said step of analyzing is responsive to sequences of digits of varying lengths.
Claim 20
Dependent Claim
71 words
The method of claim 1 further including a step of announcing to the calling party the telephone number specification that will be employed in establishing a connecting for the calling party when the step of analyzing evaluates a confidence measure and determines that the confidence measure is below a preselected threshold, and establishes said connection without performing said step of announcing when the confidence measure is not below the preselected threshold.
