MAINTAINING LOCATION BASED SERVICE SESSION CONTINUITY DURING INTER RAT MOBILITY

摘要

When a user equipment engaged in mobile communications transfers from a network with one radio access technology (RAT) to another network with a different radio access technology maintaining continuity of location based services can improve system performance. A user equipment may perform a series of checks when undergoing inter RAT transfer to determine if a location based services protocol used with the source network is operable on the target network. The UE also determines if location based services sessions are at a point where they can be continued following inter RAT transfer. Where possible protocols and sessions are maintained to preserve location based services continuity.
