    Abstract: Systems, methods, apparatuses, and computer program products for a recovery mechanism for single active protocol stack handover. A method may include performing a random access procedure with a target base station. The method may also include receiving, during the random access procedure, a random access response from the target base station. A timer may be started for a predefined duration upon receiving the random access response. The method may further include, when a random access complete message is not sent to a source base station, or a radio resource control connection reconfiguration message is not received from the source base station within the predefined duration, informing the target base station about the failure to send the random access complete message to the source base station, or the failure to receive the radio resource control connection reconfiguration message from the source base station. Handover may be completed to the target base station upon expiration of the timer.

    Abstract: A method includes determining, with a user equipment, at least one filter measurement of a signal received from a source radio node, and/or at least one filter measurement of a signal received from at least one target radio node; in response to a radio link failure with the source radio node, initiating a re-establishment procedure to become connected to the at least one target radio node, to receive access to a target cell of the at least one target radio node; and transmitting a radio link failure report to the at least one target radio node, the radio link failure report comprising: the at least one filter measurement of the signal received from the source radio node, and/or the at least one filter measurement of the signal received from the at least one target radio node; wherein the at least one filter measurement of the signal received from the source radio node, and/or the at least one filter measurement of the signal received from the at least one target radio node is configured to be used for a root-cause analysis related to at least one unfixable too-late handover or other type of problematic handover.

    Abstract: When an apparatus, which has a direct connection to a serving cell in a wireless network and a sidelink connection to a relaying apparatus at least via which data is relayed between the apparatus and the serving cell, detects a mobility event relating to the direct connection, the apparatus determines for the mobility event a target cell in the wireless network; and causes transmitting over the sidelink connection to the relaying apparatus a control signal message to be relayed to the serving cell, the control signal message indicating at least the mobility event, the target cell and an identifier of the apparatus.

    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 system, apparatus, method, and non-transitory computer readable medium for providing location management function (LMF) assisted mobility robustness optimization (MRO) may include a radio access network (RAN) node which is caused to, collect network handover information associated with at least one first user equipment (UE) device, determine whether to update a mobility policy associated with the RAN node based on the collected network handover information and a desired threshold condition, perform a first mobility policy update procedure for the RAN node based on results of the determination, receive current location information corresponding to at least one second UE device traveling between the at least one cell pair from a location management function (LMF) network device, and assign updated mobility configuration parameters to the at least one second UE device.

    Abstract: A method may include detecting, by the user device, a cell identity of a neighbor cell, determining, by the user device, whether either a first measurement by the user device of a signal from the neighbor cell after the detecting or a measurement by the user device of a signal from the neighbor cell within a threshold period of time after the detecting, at least fulfills an entry condition of a measurement reporting event for the neighbor cell, transmitting, by the user device, a measurement report based on the second time-to-trigger value if either the first measurement of a signal from the neighbor cell after the detecting or a measurement of a signal from the neighbor cell within a threshold period of time after the detecting fulfills the entry condition of the measurement reporting event, otherwise, transmitting, by the user device, a measurement report based on the first time-to-trigger value.
