Abstract: Various communication systems can benefit from signaling optimization. For example, communication systems including fourth generation (4G) and fifth generation (5G) networks may benefit from network signaling optimization for light connected mode. A method can include identifying, by a device, that a user equipment has left an area. The method can also include starting, by the device, a suspend procedure for the user equipment based on identifying that the user equipment has left the area.

Abstract: An apparatus in a source radio access node comprises means for receiving first information for determining a last packet to be forwarded to a target radio access node to which a communications device is being handed over from the source radio access node, said source radio access node providing a multicast or broadcasting service to the communications device. The means may be for causing the last packet to be forwarded from the source radio access node to the target radio access node with end information indicating that there no further packets are being forwarded.

Abstract: There is provided a method for a second network node, the method comprising: receiving a message from a first network node configured to provide a multicast-broadcast service, MBS, for a user equipment, UE, the message comprising an MBS identifier identifying the MB S and at least one data flow identifier corresponding to at least one data flow, for providing the MBS, to be offloaded from the first network node to the second network node; determining whether or not a tunnel, between the second network node and a user plane entity, associated with the MBS identifier exists; on the basis of the determining, transmitting, to the first network node, a response message indicating whether or not a new tunnel for the MBS is requested to be established; and utilizing the existing tunnel or said new tunnel requested to be established for providing the MBS.

Abstract: A first radio access network (RAN) accesses information indicating an availability status of an interface between an access and mobility management function (AMF) in a first wireless communication system and a mobility management entity (MME) in a second wireless communication system. The first RAN receives a trigger for a handover of a user equipment between the first RAN and a second RAN. The handover is selectively performed via the interface or a redirect via a network element shared by the first and second wireless communication systems based on the availability status. In some cases, the first RAN receive the information indicating the availability status prior to providing the request for the handover and stores the information in a database associated with the first RAN, which access the information from the database.

Abstract: Example embodiments generally relate to devices and methods for remapping of paging subgroups. A user equipment (UE) device may be configured to receive from a base station an explicit or implicit indication of remapping between one or more first scheme paging subgroups and one or more L1 paging subgroups, remap a first scheme paging subgroup of the UE device to a L1 paging subgroup based on the received indication of remapping, monitor for a paging early indication (PEI) from the base station including an indication of the remapped L1 paging subgroup, and receive a paging message from the base station based on the PEI.

Abstract: There is provided an apparatus, said apparatus comprising, at a multicast/broadcast session management function of a core network, means for receiving information related to a shared centralised unit user plane, CU UP for a multicast/broadcast session, from a radio access network, RAN, node or an access management function of the core network, means for determining, based on the information, whether to configure a user plane function of the core network to deliver data or to terminate delivery of data for the multicast/broadcast session towards the shared CU UP and means for, if so, configuring the user plane function to deliver data or to terminate delivery of data for the multicast/broadcast session towards the shared CU UP
