Abstract: Aspects of the present 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: There are provided measures for cell relations optimization. Such measures exemplarily comprise maintaining a table including a plurality of entries, each of said plurality of entries being assigned to a respective one of a plurality of neighboring cells, and each of said plurality of entries comprises overlapping amount information in relation to a source cell and said respective one of said plurality of neighboring cells and overlapping location information in relation to said source cell and said respective one of said plurality of neighboring cells, and utilizing said table for assessment of a suitability of each of said plurality of said neighboring cells for an inter-cell capability.
