Abstract
Abstract AIN services include multiple SCP pairs, which can be expanded to meet increased demand. The expansion can occur without cessation in services by migrating records between SCP pairs while maintaining redundancy between the pairs. A centralized GTT maintains the GTTs distributed between multiple subsystems in the AIN system. Synchronization between mate SCPs within a pair occurs at high speed as the subscriber database is split into multiple files, each file having a separate synchronization process.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
93 words
A communications system, comprising: a plurality of telephonic devices coupled to a switching network; and a service network for providing information responsive to requests for subscriber information from said switching network, comprising: database circuitry for maintaining a database of subscriber information, said database circuitry comprising a plurality of service control points, each service control point responsible for maintaining a portion of the database; and circuitry for dynamically migrating data from a first service control point to a second service control point while continuing to provide responses to said requests from said switching network.
Claim 2
Dependent Claim
93 words
A communications system, comprising: a plurality of telephonic devices coupled to a switching network; and a service network for providing information responsive to requests for subscriber information from said switching network, comprising: database circuitry for maintaining a database of subscriber information, said database circuitry comprising a plurality of service control points, each service control point responsible for maintaining a portion of the database; and circuitry for dynamically migrating data from a first service control point to a second service control point while continuing to provide responses to said requests from said switching network.
Claim 3
Dependent Claim
13 words
The communications system of claim 1 wherein said telephonic devices include mobile telephones.
Claim 4
Dependent Claim
29 words
The communications system of claim 2 wherein said telephonic devices further include base stations for receiving signals from said mobile telephones and communicating said signals to said switching network.
Claim 5
Dependent Claim
80 words
The communications system of claim 1 wherein said circuitry for dynamically migrating data performs the steps of: copying information for a predefined range of records from said first service control point to said second service control point, while said first service control point continues to respond to requests; setting flags in records in said first service control point which have changed; and updating records in said second service control point responsive to flagged records in said first service control point.
Claim 6
Dependent Claim
72 words
The communications system of claim 4 wherein said circuitry for dynamically migrating data further performs the steps of: after said copying said predefined range of records, forwarding requests for said predefined range of records to said second service control point; setting flags in records in said second service control point which have changed; and updating records in said first service control point responsive to said flagged records in said second control point.
Claim 7
Dependent Claim
30 words
The communications system of claim 5 wherein said circuitry for dynamically migrating data further performs the step of deleting said predefined range of records from said first service control point.
Claim 8
Dependent Claim
52 words
The communications system of claim 6 wherein said first and second service control points each comprise first and second subsystems, each subsystem having a copy of the portion of the database associated with the service control point and being primarily responsible for a subset of records in said portion of the database.
Claim 9
Dependent Claim
29 words
The communications system of claim 7 wherein said circuitry for dynamically migrating data further performs the step of synchronizing data between said subsystems of said first service control point.
Claim 10
Dependent Claim
40 words
The communications system of claim 8 wherein said circuitry for dynamically migrating data performs the synchronizing step by copying the portion of the database stored in its first subsystem to the first and second subsystems of said second control point.
Claim 11
Independent Claim
69 words
A method providing information responsive to requests for subscriber information from a switching network, comprising the steps of: maintaining a database of subscriber information in a plurality of service control points, each service control point responsible for maintaining a portion of the database; dynamically migrating data from a first service control point to a second service control point while continuing to provide responses to requests from the switching network.
Claim 12
Independent Claim
69 words
A method providing information responsive to requests for subscriber information from a switching network, comprising the steps of: maintaining a database of subscriber information in a plurality of service control points, each service control point responsible for maintaining a portion of the database; dynamically migrating data from a first service control point to a second service control point while continuing to provide responses to requests from the switching network.
Claim 13
Dependent Claim
78 words
The method of claim 10 wherein step of dynamically migrating data comprises the steps of: copying information for a predefined range of records from said first service control point to said second service control point, while said first service control point continues to respond to requests; setting flags in records in said first service control point which have changed; and updating records in said second service control point responsive to flagged records in said first service control point.
Claim 14
Dependent Claim
71 words
The method of claim 11 wherein said step of dynamically migrating data further comprises the steps of: after said copying said predefined range of records, forwarding requests for said predefined range of records to said second service control point; setting flags in records in said second service control point which have changed; and updating records in said first service control point responsive to said flagged records in said second control point.
Claim 15
Dependent Claim
29 words
The method of claim 12 wherein said step of dynamically migrating data further comprises the step of deleting said predefined range of records from the first service control point.
Claim 16
Dependent Claim
51 words
The method of claim 13 wherein said first and second service control points each comprise first and second subsystems, each subsystem having a copy of the portion of the database associated with the service control point and being primarily responsible for a subset of records in said portion of the database.
Claim 17
Dependent Claim
28 words
The method of claim 14 wherein said step of dynamically migrating data further comprises the step of synchronizing data between said subsystems of said first service control point.
Claim 18
Dependent Claim
41 words
The method of claim 15 wherein said synchronizing step comprises the step of copying the portion of the database stored in the first subsystem of the first service control point to the first and second subsystems of the second control point.
