    Abstract: A method detecting at least one of a mobility failure and a respective successful handover; determining a type of the mobility failure, wherein the type of the mobility failure is determined in response to the detected mobility failure; generating mobility failure information indicative of one or more parameters associated with the type of mobility failure, wherein the mobility failure information is generated, at least in part, based on the determined type of the mobility failure; and providing the mobility failure information and/or successful handover information including, at least in part, one or more parameters associated with the respective successful handover, wherein mobility failure information and/or successful handover information enable a network to determine whether a root cause associated with at least one of a respective mobility failure information and a respective successful handover information is a misconfiguration of one or more parameters controlling L3 handover procedures or L1/2 inter-cell mobility.

    IPC: H04W36/00

    Abstract: A method including receiving, from a second cell, a paging message associated with a network slice supported by a first cell, wherein the paging message includes at least an indication indicating to wait for a command indicative of performing a re-direction or a handover from the second cell to the first cell before transmitting a service request to a network associated with the first cell and the second cell; performing, by the terminal device, the re-direction or the handover from the second cell to the first cell upon receiving the command; and transmitting, through the first cell, the service request upon completing the re-direction or the handover from the second cell to the first cell, wherein the service request indicates a request for establishing a protocol data unit session associated with the network slice.

    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: 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.
