Abstract

A method and apparatus for dynamically maintaining a subscriber database of a cellular telecommunications system. The method and apparatus allows creation of a personalized location pointer structure, personalized subscriber database and personalized outgoing call search list for an individual mobile subscriber. The personalized pointer structure, personalized subscriber database and personalized search list are determined based on mobile subscriber movement history and behavior within the system. Each of the location pointer structure, subscriber database and search list may be reconfigured as the system operator desires to account for changes in mobile subscriber behavior.

Claims

1. In a telecommunications system comprising a plurality of mobile stations and a plurality of data nodes, each of said data nodes including at least one base station having a coverage area, and wherein each of said plurality of mobile stations is capable of making calls to and receiving calls from one of a plurality of subscribers, each of said subscribers being associated with a directory number and having a subscriber profile, a method of directing a call from an originating subscriber to a called subscriber, said method comprising the steps of:

maintaining a record for at least one directory number called by the originating subscriber, said record comprising data associated with calls to said at least one directory number and being updated at each call made by the originating subscriber to said at least one directory number;

determining if said data indicates that calls to said at least one directory number meet a selected criterion; and

in response to an affirmative determination in said step of determining;

placing said at least one directory number in a database of stored directory numbers within the subscriber profile of the originating subscriber, said database being located at at least one of said plurality of data nodes.

2. The method of claim 1 in which each stored directory number in said database is associated with a data node and, in which said method further comprises the steps of:

determining that the originating subscriber has made a call to a selected directory number of the stored directory numbers within said database; and

directing signaling for setup of said call directly to the data node associated with said selected directory number.

3. The method of claim 1 in which a data node associated with said at least one directory number is a home data node of said at least one directory number.

4. The method of claim 1 in which said step of determining comprises calculating a value dependent on the number of calls made to said at least one directory number from the originating subscriber.

5. The method of claim 4 in which said value calculated in said step of determining further depends on the time of said call.

6. In a telecommunications system comprising a plurality of mobile stations and a plurality of data nodes, each of said data nodes including at least one base station having a coverage area, and wherein each of said plurality of mobile stations is capable of making calls to and receiving calls from one of a plurality of subscribers, each of said subscribers being associated with a directory number and having a subscriber profile, an apparatus for directing a call from an originating subscriber to a called subscriber, said apparatus comprising:

means for maintaining a record for at least one directory number called by the originating subscriber, said record comprising data associated with calls to said at least one directory number and being updated at each call made by the originating subscriber to said at least one directory number;

means for determining if said data indicates that calls to said at least one directory number meet a selected criterion and generating a signal in response to an affirmative determination; and

means for placing said at least one directory number in a database for stored directory numbers within the subscriber profile of the originating subscriber in response to said signal generated in said means for determining, said database being located at at least one of said plurality of data nodes.

7. The apparatus of claim 6 in which each stored directory number in said database is associated with a data node and, in which said apparatus further comprises:

means for determining that the originating subscriber has made a call to a selected directory number of the stored directory numbers within said database; and

means for directing signaling for setup of said call directly to the data node associated with said selected directory number.

8. The apparatus of claim 6 in which a data node associated with said at least one directory number is a home data node of said at least one directory number.

9. The apparatus of claim 7 in which said means for determining comprises means for calculating a value dependent on the number of calls made to said at least one directory number from the originating subscriber.

10. The apparatus of claim 9 in which said value calculated by said means for determining further depends on the time of said call.

11. In a telecommunications system comprising a plurality of mobile stations and a plurality of data nodes, each of said data nodes including at least one base station having a coverage area, and wherein each of said plurality of mobile stations is capable of making calls to and receiving calls from one of a plurality of subscribers, each of said subscribers being associated with a directory number and having a subscriber profile, an apparatus for directing a call from an originating subscriber to a called subscriber, said apparatus comprising:

a record maintainer for maintaining a record for at least one directory number called by the originating subscriber, said record comprising data associated with calls to said at least one directory number and being updated at each call made by the originating subscriber to said at least one directory number;

a determiner for determining if said data indicates that calls to said at least one directory number meet a selected criterion and generating a signal in response to an affirmative determination; and

a database of stored directory numbers within the subscriber profile of the originating subscriber, wherein said at least one directory number is stored in said database in response to said signal generated in said means for determining, said database being located at at least one of said plurality of data nodes.
