Abstract: There is herein disclosed a method for receiving, from a radio access network node, a conditional handover configuration for a plurality of target cells and a radio condition for conditional handover of the UE for a plurality of target cells. The method further comprises receiving, from the radio access network node, an indication that the UE is allowed to select and connect to a preferred target cell from the plurality of target cells. The method further comprises selecting the preferred target cell from the plurality of target cells based on network slice area of service availability information for each target cell configured at the UE and the radio condition and transmitting, a request to connect to the preferred target cell.

Abstract: The present invention relates to survival time aware mobility and presents handover procedures when considering survival time (ST) requirements. It proposes a mechanism and embodiments to allow a target cell to have the information relating to a joining UE's Survival Time requirements as well as the ST status during the handover procedure. In particular, the invention is aimed at being introduced into the mobility procedures: Baseline Handover (BHO), Conditional HO (CHO), and Dual Active Protocol Stack (DAPS) HO. In addition to the aggregated RAN architecture, the mobility procedures can be applicable to disaggregated RAN architecture, e.g., CU-DU split.

Abstract: Aspects of the invention pertain to a method, comprising receiving a preparatory handover request pertaining to at least one or more physical resources, respectively associated to a particular communication service, preliminarily deciding on the feasibility of such preparatory handover request for each of said at least one or more physical resources associated to the particular communication service dependent on at least one feasibility criterion, and validating the preliminary decision on the feasibility of the preparatory handover request dependent on at least one validation criterion. Likewise, corresponding apparatus and computer program products are addressed, both from network entity perspective such as a gNB, as well as from a terminal's perspective, e.g. from a UE perspective.

Abstract: Systems, methods, apparatuses, and computer program products for source cell to provide a service/slice indication to the target cell in the handover preparation. The source cell provides to a target cell a list of one or more service/slice specific indications for individual ones of one or more network slices in a request for enhanced handover from the source cell to the target cell in a handover preparation phase. The source cell receives from the target cell, indications in a handover request acknowledgement of one or more selected network slices to be handed over from the source cell to the target cell using enhanced handovers. Performs make-before-break handovers to hand over these selected network slices from the source cell to the target cell and performs normal handovers for the one or more other network slices.

Abstract: A UE may determine that at least one execution condition for performing handover from a source cell to a target cell is met and the target cell does not support at least one of a network slice or a service the UE requires; based on the determination, store information related to a radio environment associated with the UE; perform handover to the target cell; and transmit the stored information to the target cell after the handover. A target network node may receive the transmitted information; and provide the information to a source network node. The source network node may receive the information; and perform a root cause analysis for the handover execution of the user equipment based, at least partially, on the received information.

Abstract: There are provided measures for feedback on network-assisted fallback to contention-based random access. Such measures exemplarily comprise, at a terminal connected to at least one network slice and being subject to a handover from a source access point to a target access point, receiving a handover command message including handover assistance information indicative of a first pool of random access channel resources to be used by said terminal upon fallback to contention-based random access during a handover processing, selecting first random access channel resources as attempt random access channel resources from said first pool of random access channel resources, attempting random access to said target access point utilizing said attempt random access channel resources, storing, if said attempting random access to said target access point utilizing said attempt random access channel resources is unsuccessful, attempt related information to an attempt failure list, and transmitting, if said attempting random access to said target access point utilizing said attempt random access channel resources is successful, said attempt failure list to said target access point.
