Abstract: Techniques of mobility events include generating, by a gNB-CU-CP, preconfigured target cell configurations for some or all intra-frequency cells of a gNB-DU which reduces the need for subsequent F1:UE Context Modification and RRC Re-configuration procedures to configure cells of the same DU for L1/L2 mobility. Advantageously, the above-described technique for intra and inter gNB-DU mobility provides for more efficient signaling between cells belonging to the same gNB-DU.

Abstract: There are provided measures for robust mobile terminal handover. Such measures exemplarily comprise, at a distributed unit of an access network node, receiving, from a centralized unit of said access network node, a handover message including an indication indicative of that a handover of a terminal is to be reserved, the handover message including at least one handover related radio resource control reconfiguration corresponding to at least one handover target cell and at least one resume condition corresponding to said at least one handover target cell, inhibiting, based on said indication, forwarding of said at least one handover related radio resource control reconfiguration towards said terminal, storing each of said at least one handover related radio resource control reconfiguration, evaluating fulfillment of each of said at least one resume condition, and if, as a result of said evaluating, a first resume condition of said at least one resume condition corresponding to a first handover target cell of said at least one handover target cell is fulfilled, deciding to transmit, despite said indication indicative of that said handover of said terminal is to be reserved, a first handover related radio resource control reconfiguration of said at least one handover related radio resource control reconfiguration towards said terminal, wherein said first handover related radio resource control reconfiguration corresponds to said first handover target cell.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for NG based context release and data forwarding for multi-hop mobility. In an example implementation, the method may include a core network entity receiving a first message from a first network node, the first message including at least one of a user equipment context release request and a data forwarding request and detecting the at least one of the user equipment context release request and the data forwarding request from the first message. The method may further include sending a second message including at least one of a user equipment context release command and data forwarding information to a second network node based at least on the detected at least one of the user equipment context release request and the data forwarding request.
