Abstract

A service request is received and associated with a subscriber id. Profile information is accessed for the source of the service request. A copy of the profile information is stored in a network element employed by the source of the service request to access the network.

Claims

1. A method comprising:

associating a subscriber id with a service request;

accessing from a database profile information for a source of a service request;

communicating a copy of the profile information from the database to a network element employed by the source of the service request to access the network, the network element producing updates to the copy of the profile information; and

an HLR communicating a copy of the profile information to an MSC employed by the source of the service request to access the network.

2. The method of claim 1 further comprising:

referring to the copy of the profile information in response to a query.

3. The method of claim 1 further comprising:

the network element updating the copy of the profile information; and

the network element causing the updates to the copy of the profile information to be stored in a permanent record of the profile information.

4. The method of claim 1 further comprising:

an HLR storing the permanent record of the profile information.

5. The method of claim 1 further comprising:

the network element providing the copy of the profile information in response to a query for the profile information from another network element.

6. A network element comprising:

profile information for a plurality of subscribers to a network;

logic to receive service requests from the plurality of subscribers and to communicate copies of the profile information for the plurality of subscribers to those network elements by which the subscribers access the network; and

logic to provide the appearance that the copies of the profile information are stored in a central location;

wherein an HLR communicates a copy of the profile information to an MSC employed by a source of the service request to access the network.

7. The network element of claim 6 wherein the profile information further comprises:

identification of the services each of the subscribers is authorized to access; and

terminal profile information for each of the subscribers.

8. The network element of claim 7 wherein the profile information further comprises at least one of:

service provision information and service delivery information for each subscriber.

9. A network comprising:

a plurality of MSCs, each MSC comprising profile information for at least one of those subscribers, users, and terminals accessing the network via the MSC; and

at least one of an HLR and HSS comprising logic to include the profile information of each MSC of the plurality of MSCs when forming responses to queries for profile information.

10. The network of claim 9 wherein the at least one of an HLR and HSS further comprises:

master copies of profile information for subscribers of the network; and

logic to communicate a copy of at least some of the master copies of the profile information to the MSCs.

11. The network of claim 9 wherein each MSC of the plurality of MSCs comprises:

logic to update the copies of the at least some of the master copies of the profile information according to usage by the subscribers and to record the updates to the copies in the at least one of the HRL and HSS.

12. A method comprising:

receiving profile information for a roaming subscriber from a home network of the roaming subscriber, the profile information received by a network element by which the subscriber accesses the roaming network;

updating the profile information using the network element and with usage information for the subscriber, using an MSC; and

communicating the updated profile information to the home network.

13. A method comprising:

a first MSC receiving a copy of master profile information from an HLR;

the first MSC updating the copy of master profile information with usage statistics for a network subscriber; and

the first MSC communicating the updated copy of the profile information to a second MSC when the subscriber begins using the second MSC to access the network.

14. The method of claim 13 further comprising:

the second MSC updating the updated copy of master profile information with usage statistics for the network subscriber.

15. The method of claim 13 further comprising:

the second MSC causing updates to the profile information to be stored in the master copy of the profile information.

16. A network element comprising:

profile information for a plurality of subscribers to a network;

logic to receive service requests from the plurality of subscribers and to communicate copies of the profile information for the plurality of subscribers to those network elements by which the subscribers access the network;

logic to provide the appearance that the copies of the profile information are stored in a central location; and

the profile information and the copies of the profile information comprising XML-style data fields and XML-style relationships between data fields;

wherein an HLR communicates a copy of the profile information to an MSC employed by a source of the service request to access the network.
