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.
