Abstract: Systems and methods to utilize user device network slicing and cell support to manage handover of communications for user device. A request to handover management of a user device from a first cell to a second cell is received. One or more possible cells for the handover are then identified. If the user device is utilizing network slicing, then the second cell is selected from the one or more possible cells based on that cell also supporting network slicing. If the cell supports the same network slice as being utilized by the user device, then the handover of the user device to the second cell is initiated.

Abstract: An SMF sends, to an AMF, a first message comprising a PDU session identifier of a PDU session for a wireless device, wherein the PDU session is associated with a network slice. The SMF receives, from the AMF, a second message comprising an indication that the network slice is not available at a location of the wireless device. After receiving the second message, the SMF does not send, to the AMF, an indication of data arrival of the PDU session.

Abstract: A cell reselection method performed by a user equipment in a mobile communication system includes: receiving, from a network, slice frequency information indicating a correspondence relationship between network slice groups, frequencies, and frequency priorities; determining, for a selected network slice group selected by a user equipment in accordance with a slice group priority, priority orders of corresponding frequencies based on the frequency priorities indicated by the slice frequency information; and reselecting a candidate cell satisfying a predetermined quality standard within a selected frequency selected by the user equipment in accordance with the determined priority orders. The determining of the priority orders includes determining, for each of the frequencies, the priority orders of the corresponding frequencies, based on a maximum value of the frequency priorities for each of a plurality of network slice groups when the plurality of network slice groups have a same slice group priority.

Abstract: Systems, apparatuses, methods, and computer programs that communicate with a User Equipment (UE) device that is simultaneously using a first wireless communication protocol and a second wireless communication protocol; determine the UE device is proximate to a neighbor cell; determine the neighbor cell is absent from a neighbor relations table; cause the UE device to cease simultaneously using the first wireless communication protocol and the second wireless communication protocol; cause the UE device to only use the first wireless communication protocol; receive information while the UE device is only using the first wireless communication protocol; and use the information to add the neighbor cell to the neighbor relations table.

Abstract: A handover processing method, a terminal, and a storage medium are provided. The method includes the following. The terminal acquires at least one handover command, the at least one handover command including at least one of a first handover command, a second handover command, and a conditional handover command, where the first handover command is indicated through layer 1 or layer 2 signaling and the second handover command being indicated through layer 3 signaling. The terminal determines, according to the at least one handover command, a handover command to be preferentially executed. The terminal performs cell handover according to the handover command to be preferentially executed.

Abstract: An apparatus for transmitting and receiving signals, the apparatus being applicable to a process of migrating an IAB-node under control of a first donor central unit (donor-CU) from a first distribution unit (DU) to a second DU, and being arranged in the first donor-CU, wherein the apparatus includes a memory, and a processor coupled to the memory and configured to transmit one or more first path migration configurations for an integrated access and backhaul node (IAB-node), and transmit one or more second path migration configurations for a child node, wherein the first path migration configurations correspond to a parent node to which a first candidate cell of the IAB-node belongs, and the second path migration configurations correspond to a parent node to which the second candidate cell of the IAB-node belongs.
