Abstract: Disclosed are methods and systems for prioritizing cell selection for availing LADN services. A UE prioritizes cells for selection based on availability of LADN services in the cells. For handover, a base station of a cell, providing LADN services to the UE, prioritizes target cells that provide LADN services that are being currently availed by the UE for ensuring LADN service continuity. The base station initiates addition of secondary cells that provide additional LADN services that are intended by the UE. The UE can predict if a paging message is relevant to a LADN service and send serving requests to the serving cell or other cells to avail the LADN service. The UE detects relay UEs providing LADN services and prioritizes the relay UEs for selection based on availability of LADN services. The UE buffers data if the UE is located at an edge of a LADN service area.
