Abstract: A method includes transmitting an indication to create a notification publish space to a data storage function, the notification publish space including an identifier of a central entity of an access network node being monitored for failure; receiving an acknowledgement of the indication to create the notification publish space from the data storage function; and transmitting the identifier of the central entity and associated publish space information to at least one logical entity of the access network node or of another access network node being monitored for failure; wherein the identifier of the central entity is configured to be used with the at least one logical entity to subscribe to the notification publish space to receive information concerning a failure of the at least one logical entity of the access network node or of the another access network node.

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 computer program is described comprising: receiving a first register request from a first node of a mobile communication system at a network repository function of a mobile communication system, wherein the first register request registers parameters or capabilities of the first node in the network repository function to enable the network repository function to provide information relating to said parameters or capabilities to a second node of the mobile communications system, wherein at least one of the first and the second node is an access node of the mobile communication system.

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.

Abstract: An apparatus for retrieving at least one of an access network or core network assigned user equipment identifier (NGAP ID) from outside of the access or core network using IP addressing information. The apparatus configured to receive IP addressing information of the user equipment; determine a subscriber permanent user identity for the user equipment from the IP addressing information; generate and transmit a request for the at least one of the access network or core network assigned user equipment identifier, the request including the subscriber permanent identity; and receive the at least one of the access network or core network assigned user equipment identifier.
