Abstract: A method, apparatus and computer program product are provided herein to provide service continuity between a Stand-alone Non-Public Network (SNPN) and a Public Land Mobile Network (PLMN). For example, a method is provided that comprises after determining that the user equipment (UE) with the first protocol data unit (PDU) session established in the first SNPN is or will be leaving the coverage area of the first SNPN, causing a request message to be transmitted to the UE, wherein the request message comprises a request to initiate a second PDU session establishment procedure towards a PLMN. The method also includes causing the UE to establish the second PDU session with an internet protocol anchor function of a user plane function in the PLMN via the first SNPN radio access network (RAN) or via the PLMN RAN, wherein the second PDU session is established prior to release of the first PDU session.

Abstract: Systems, methods, apparatuses, and computer program products for defining service area(s) for time synchronization. A method may include receiving, at a user equipment, time synchronization service area information from a network node in a network. The method may also include selecting a cell for connection based on the time synchronization service area information. The selected cell may maintain a time domain required by the user equipment to remain synchronized with the network.
