Abstract: An apparatus comprising means for sending a response to the first target master node based on the received first request in response to receiving a first secondary node addition request for the user equipment from a first target master node, means for sending a response to the second target master node based on the received second request in response to receiving a second secondary node addition request from a second target master node for the same user equipment; and means for enabling, in response to receiving a physical uplink shared channel message from the user equipment, decoding of the physical uplink shared channel message received from the user equipment based on a first target master node key associated with the first target master node in case no information is available whether user equipment accessed first or second target master node, and, if decoding with the first key not successful, decoding based on a second target master node key associated with the second target master node.

Abstract: The present invention is about conditional handover (CHO) in telecommunications networks, and a main point is to pass the responsibility to a target Master Node for triggering the UE to rapid access to Primary Secondary Cell after applying target Primary Cell configuration during a CHO-NR-DC handover. The target MN decides whether to wait further to execute CPC. If measurements are hopeful, completion of execution of the primary secondary cell for dual connectivity is postponed, and L3 measurement results are inspected from the UE. There are three variants, when the target MN requests the UE to access the target Secondary Node; namely RRC-based access target SN trigger, PDCCH-order-based variant and DL MCE-based variant.

Abstract: Example embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage medium for distributed non-access stratum (NAS). The method comprises: providing, to a second apparatus, a NAS message transport configuration indicating at least one of a mapping between NAS services and radio bearers or a mapping between NAS services and NAS service type identifiers; and routing an NAS message between the second apparatus and a third apparatus based at least on the NAS message transport configuration, wherein the third apparatus is determined from a plurality of apparatuses based on the NAS message transport configuration.

Abstract: In accordance with an example embodiment of the present disclosure an apparatus that is caused to receive, at a central unit, CU, a first indication of a random access, RA, attempt associated with a first user equipment, the first indication comprising a RA preamble ID, RAPID; a RA radio network temporary identifier, RA-RNTI; and an identifier of a target cell; to start a collision detection timer responsive to receiving the first indication; and to determine a preamble collision related to timing advance, TA, acquisition in a Layer1/Layer2 triggered mobility procedure, responsive to receiving, at the CU, during the collision detection timer is running, a second indication of an RA attempt associated with a second user equipment, the second indication comprising the same RAPID, RA-RNTI and identifier of the target cell as the first indication.
