Systems and Methods for Subscriber Profile Management
First Claim
1. A subscriber profile management system that generates and manages a time to live (TTL) limit for a subscriber of a home network, comprising:
- a time to live (TTL) generator that generates a TTL limit for a subscriber based on usage characteristics of the subscriber;
wherein the TTL limit specifies a time limit for which a subscriber profile is to remain active within a visited network when the subscriber accesses the visited network, andan administration module that administers the TTL limits.

Abstract
Systems and methods subscriber profile management to facilitate seamless roaming of mobile devices from one network to another. A subscriber profile management system is provided that includes a time to live (“TTL”) generator that generates a TTL limit for a subscriber based on usage characteristics of the subscriber. The subscriber profile management system further includes an administration module that administers TTL limits, TTL limit database that store TTL limits, a subscriber profile database that stores subscriber profiles, a usage measurement database that stores usage measurements, and a TTL limit reference module that administers TTLs when a subscriber profile and TTL limit are transmitted. The invention further includes a series of methods that support seamless roaming capabilities of a subscriber throughout visited networks without the need to continually make proxy calls to re-authenticate a subscriber.

10. A subscriber profile management system that manages time to live (TTL) limits for a visiting subscriber having a home network when the visiting subscriber visits a visited network, comprising:
-
a TTL limit database that stores TTL limits for visiting subscribers when visiting subscribers have been granted network access to a visited network, wherein the TTL limit specifies a time limit for which a subscriber profile is to remain active within the visited network when the visiting subscriber accesses the visited network; a subscriber profile database that stores visiting subscriber profiles when visiting subscribers have been granted network access to a visited network; and an administration module that administers subscriber profiles and TTL limits, wherein subscribers are from a home network that differs from the network in which the subscriber profile management system resides. - View Dependent Claims (11, 12, 13)

14. A method for a visited network to provide a service to a visiting subscriber having a home network, comprising:
-
(a) receiving a service request from the visiting subscriber in a visited network service area; (b) requesting a subscriber profile and time to live (TTL) limit, wherein the TTL limit specifies a time limit for which the visiting subscriber profile is to remain active within a visited network when the visiting subscriber accesses a visited network; (d) receiving the visited subscriber profile and TTL limit; (e) caching the visiting subscriber profile and TTL limit; and (f) providing the service to the visiting subscriber. - View Dependent Claims (15, 16, 17)
