Abstract: A method includes receiving, by a first network node that is configured as a master node from a second network node that is configured as a source secondary node for dual connectivity for a user device, control information indicating whether or not the first network node may receive from the second network node an updated measurement configuration based on a list of accepted target Primary Secondary Cells (PSCells) that are accepted by the target secondary node among a list of candidate target PSCells; sending to the user device, a conditional reconfiguration message including the initial measurement configuration that is based on the list of candidate target PSCells if the control information indicated that the first network node will not receive from the second network node an updated measurement configuration; and otherwise, sending a conditional reconfiguration message including the updated measurement configuration that is based on the list of accepted target PSCells.

Abstract: Aspects and embodiments relate to apparatus configured to delay execution of an action based on an execution delay and methods to delay execution of an action. In particular, the example embodiments provide apparatus and methods to delay execution of mobility related events, for example, handover. One aspect provides an apparatus, comprising: at least one processor; and at least one memory storing instructions that when executed by the at least one processor cause the apparatus at least to: obtain an indication of an execution delay to be applied by the apparatus in relation to an action to be executed by the apparatus, the execution delay being based upon one or more operational characteristic of the apparatus; determine that the action is to be executed by the apparatus; and delay execution of the action based on the execution delay. Arrangements and implementations provide a mechanism to mitigate RACH load congestion. Arrangements provide mechanisms to distribute a handover execution load (in the form, for example, of RACH attempts initiated by UE) across a restricted or limited time period.

Abstract: Techniques for coordination between nodes for measurement configuration in a Primary Secondary Cell Group (SCG) Cell (PSCell) change procedure in cellular wireless communication networks are provided. For example, a method for a Primary Secondary Cell Group (SCG) Cell (PSCell) change procedure is provided. The method comprises: sending, from a master node (MN) to a target secondary node (T-SN), a first message (e.g., an SN Addition Request message) including configuration information based on which the T-SN determines whether to provide a full configuration or a delta configuration for measurement-related information for one or more candidate target PSCells acknowledged by the T-SN; and receiving, at the MN from the T-SN in accordance with the configuration information, a second message (e.g., an SN Addition Request Acknowledge message) including the full configuration or the delta configuration for measurement-related information for the one or more candidate target PSCells acknowledged by the T-SN.

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: 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: There are provided measures for enabling/realizing an early evaluation for conditional reconfiguration in a mobile/wireless communication system. Such measures exemplarily include that a communication entity obtains an evaluation measurement configuration and an evaluation candidate cell set, performs an evaluation measurement in accordance with the evaluation measurement configuration on the evaluation candidate cell set, and performs or starts evaluating an execution condition for conditional reconfiguration for the evaluation candidate cell set on the basis of a result of the evaluation measurement, in the absence of and/or prior to availability of an actual configuration for conditional reconfiguration.

Abstract: A base station, in communication with a UE using a first serving cell, determines a need to perform a security update for the UE and sends a command including information to perform the security update and indication of a time to execute the security update to change to a new security configuration. In response to the time occurring, a security update is performed to a new security configuration for use for communication with the UE using a second serving cell. The UE receives the information and the indication and performs, without performing a random-access procedure, the security update to the new security configuration to use for communication with the second serving 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: 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: An apparatus performs evaluating, with a user equipment of a communication network, before detaching from a source cell a conditional handover execution condition fulfillment for a conditional handover with the user equipment from the source cell to at least one target cell of the communication network; and based on the evaluating, detaching from the source cell for performing the conditional handover to a target cell of the at least one target cell. Further, an apparatus performs sending toward user equipment information comprising a configuration of a conditional handover, wherein the information causes the user equipment to evaluate a conditional handover execution condition fulfillment before detaching from the source cell for at least one target cell based on an indication of the conditional handover execution condition fulfillment to a first target cell of the at least one target cell that does not support a dual active protocol stack configuration.
