<p>A wireless mobility management system including a visitor location register configured to store a visiting user profile and communicate with a mobile switching center to route a wireless call supporting a user-session, a home location register configured to store a home user profile and update a user location associated with the home user profile, and a wireless media gateway (WMG) configured to create a user-session interconnection between a first wireless network and at least one of a second wireless network, a wireline packet network and a public-switched telephone network, including providing physical resources for the user-session. A WMG controller integrated with a wireless softswitch is configured to control the WMG to allocate resources and establish connections as required by the user session. A performance-based mobility manager is configured to receive user-session performance data from the WMG and make a handoff decision based on the performance data.</p> |
