Mobility management apparatus and methods
First Claim
1. A wireless mobility management system, comprising:
- 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;
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 and configured to control the WMG to allocate resources and establish connections as required by the user session; and
a performance-based mobility manager configured to receive user-session performance data from at least one of the WMG and the WMG controller, and thereafter make a handoff decision based on the received performance data.

Abstract
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.

8. A mobility management system, comprising:
-
a location management module configured to update a location and profile of a wireless subscriber and determine a serving visitor location register (VLR) and location of a called party; and
a handoff management module configured to initiate handoff based on performance data of a subscriber-session, establish a new connection for the subscriber-session, and transfer the subscriber-session from an existing connection to the new connection. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method for performance-triggered handoff of a wireless call, comprising:
-
monitoring performance data, including at least one of;
packet media performance data of the wireless call at a wireless media gateway;
signaling level performance data of the wireless call at a wireless media gateway controller;
sending a notification message to a mobility manager module when the monitored performance data indicates performance deterioration beyond a predetermined threshold;
initiating handoff of the wireless call based on the monitored performance data and receipt of the notification message by the mobility manager module;
sending a first handoff message to an MSC/VLR module configured to operate as both a mobile switching center and a visitor location register; and
sending a second handoff message to a mobile terminal of the wireless call. - View Dependent Claims (19, 20)
