ABSTRACT:
The system for frame selector migration in 3G cellular networks enables the frame selector function to be migrated to the presently active Radio Network Controller without disruption of the call. This migration strategy functions to reduce the number of handoff legs required to serve an existing call connection, therefore more efficiently utilizing the network resources. The system for frame selector migration in 3G cellular networks also optionally uses a hierarchy of frame selectors, which makes use of multiple levels of frame selectors in the cellular network to simplify the migration of the frame selector function.
