Abstract: Various example embodiments relate to a solution for modifying mobility events by making them depend on information which captures a moving cell direction. A network node may obtain coverage information associated with a serving network and a target network. The network node may obtain synchronization signal timing data associated with the target network. The network node may determine time drift rate data for at least one user node based at least partly on location data and satellite ephemeris data. The network node may cause transmission of the time drift rate data associated with the time drift to the at least one user node to enable the user node to perform a measurement of a target cell of the target network using the time drift rate data. Nodes, methods, and computer programs are disclosed.

Abstract: The present invention discloses an apparatus, for use by a cell in a non-terrestrial network, comprising means for performing transmitting, to a user equipment, information indicating ephemeris corresponding to the cell and information indicating ephemeris corresponding to at least one neighboring cell, wherein the neighboring cell is detectable at the user equipment when the user equipment is in coverage of said cell.

Abstract: An apparatus, method and computer program is described comprising: determining, at a user device of a mobile communication system, one or more parameters of a serving cell and one or more target cells at a first time instance; and estimating one or more time delay metrics for each of the one or more target cells based on said parameters, such that an optimal time point for performing a handover can be determined. The time delay metrics comprise one or more of: a first time delay corresponding to a time period between the first time instance and a time instance at which a signal strength of the serving cell is predicted to match a signal strength of the respective target cell; and a second time delay corresponding to a time period between the first time instance and a time instance at which the signal strength of the respective target cell is predicted to be higher than the signal strength of the serving cell by an offset value.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for proactive triggering of handovers in wireless communication networks.

Abstract: Where a UE moves between primary and/or secondary cells, the repeated reconfiguration of a UE at the network requires repeated signalling. Where non terrestrial networks nodes provide cells it may be possible to predict which cells a UE is likely to visit and when, based on the satellite movement. Embodiments make use of this ability to predict multiple future cells by transferring configuration information for a series of target cells in a single message, in some cases along with condition information indicating when the cell is likely to be providing radio coverage for that UE. Furthermore, to reduce signalling overhead some of the information is provided as a delta information, that is as an indication of how a previous configuration will change to provide the new configuration. A UE can apply the configuration information as the conditions become fulfilled.

Abstract: A method for admission control including transmitting a first admission request to a distributed unit of the IAB donor, wherein the first admission request includes information about a resource set to be established for a terminal device; receiving a first admission response from the distributed unit indicating whether one or more resources in the resource set are to be accepted; transmitting a second admission request to each of at least one IAB node including information about the resource set; receiving a second admission response from each of the at least one IAB node indicating whether one or more resources in the resource set are to be accepted; and in response to determining that at least one resource in the resource set is to be accepted, transmitting to an IAB node serving the terminal device a request for establishing a context of the terminal device including information about the resource.

Abstract: A shortage of at least one resource is determined in a first radio network control entity that has joined a pool of radio network control resources. The first radio network control entity signals to at least one second radio network control entity of the pool a request for at least one resource. The at least one second radio network control entity receives the request for at least one resource and offers for the first radio network control entity.

Abstract: A method of accomplishing switchover from an inservice local to a remote NP (Network Processor) is described. The remote NP is periodically updated with configuration data obtained from the inservice local NP. Switchover from the local inservice NP to the remote NP is initiated. Communications between the remote NP and a plurality of NEs (Network Elements) is established nonsynchronously. The local NP is notified that the remote NP is established as an inservice NP.
