Abstract

A telecommunication network includes a first telecommunication switch that supports subscribers coupled to the first switch and recognizes a request for call origination by a calling party on an associated communication line. The request for call origination services seeks services from a second switch. A first record in a database coupled to the second switch is located based on the identification of the calling party'"'"'s line. The second switch is disposed at a hierarchical level above the first switch. A first set of predetermined features is determined based on information contained in the first record. A personal identification number of the calling party is received at the second switch. A second record in a database is located based upon the PIN; the second record is independent from the first record. A second set of predetermined features is determined based upon information contained in the second record. The set of features made available to the calling party from the second switch is determined based on a consideration of the total set of call features in the first and second sets of features.

Claims

1. In a telecommunication network having a first telecommunication switch that supports subscribers coupled to the first switch, a method for controlling features made available to a subscriber comprising the steps of:

recognizing, at the first switch, a request for call origination by a calling party on an associated communication line, the request being for call origination services to be provided by a second switch;

conveying the call origination request from the first switch to the second switch disposed at a hierarchical level above the first switch;

locating a first record in a database coupled to the second switch based on the identification of the calling party'"'"'s line;

determining a first set of predetermined call features based on information contained in the first record;

receiving at the second switch a personal identification number (PIN) entered by the calling party via said associated communication line;

locating a second record based on the PIN in the database coupled to the second switch, said second record independent of said first record;

determining a second set of predetermined call features based on information contained in the second record;

determining a third set of call features that is made available to the calling party based on call features contained in said first and second sets of features, whereby call features associated with a particular line can be supplemented by other call features associated with the PIN of a particular subscriber.

2. The method according to claim 1 wherein said determining of the third set of call features comprises selecting all call features found in any of the first and second sets of features.

3. The method according to claim 1 wherein said determining of the third set of call features comprises selecting only the call features contained in the second set of call features.

4. The method according to claim 1 further comprising the steps of receiving a predetermined authorization code at the second switch from the calling party and validating said authorization code prior to making any call features contained in the second set of call features available to the calling party.

5. In a telecommunication network having a first telecommunication switch that supports subscribers coupled to the first switch, the improvement comprising:

means for recognizing, at the first switch, a request for call origination by a calling party on an associated communication line, the recognizing means recognizing the request being for call origination services to be provided by a second switch;

means for conveying the call origination request from the first switch to the second switch disposed at a hierarchical level above the first switch;

means for locating a first record in a database coupled to the second switch based on the identification of the calling party'"'"'s line;

means for determining a first set of predetermined call features based on information contained in the first record;

means for receiving at the second switch a personal identification number (PIN) entered by the calling party via said associated communication line;

means for locating a second record based on the PIN in the database coupled to the second switch, said second record independent of said first record;

means for determining a second set of predetermined call features based on information contained in the second record;

means for determining a third set of call features that is made available to the calling party based on call features contained in said first and second sets of features, whereby call features associated with a particular line can be supplemented by other call features associated with the PIN of a particular subscriber.

6. The network according to claim 5 wherein said means for determining the third set of call features comprises means for selecting all call features found in any of the first and second sets of features.

7. The network according to claim 5 wherein said means for determining the third set of call features comprises means for selecting only the call features contained in the second set of call features.

8. The network according to claim 5 further comprising means for receiving a predetermined authorization code at the second switch from the calling party and means for validating said authorization code prior to making any call features contained in the second set of call features available to the calling party.
