Title:
ＲＡＴ間モビリティ中にロケーションベースサービスセッション継続性を維持すること
Document Type and Number:
Japanese Patent JP5781695
Kind Code:
B2
Abstract:
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.
