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.

Abstract: Example embodiments enable controlling consumption of additional resources required for performing data collection in a radio access network by estimating costs associated with various data collection tasks. The costs may be exposed to data consumers such that is possible to keep the additional resource consumption within cost budget(s) allocated for particular data consumers, network nodes, and/or network interfaces. Example embodiments enable preventing excessive data collection load, which may be for example caused by various machine learning tasks performed at the radio access network. Apparatuses, methods, and computer programs are disclosed.

Abstract: Systems, methods, apparatuses, and computer program products for distinguishing minimization of drive tests (MDT) logging through different radio resource controller (RRC) states. One method may include receiving, from a network element, a logged measurement configuration comprising specific content for a user equipment depending on a connection state of the user equipment. The method may also include validating the logged measurement configuration, wherein the validating is embodied by the network element prior to transitioning to a different user equipment state, or by a user equipment after entering a logging state, for which the logged measurement configuration was designated. The method may further include performing logging of a measurement according to the content of the logged measurement configuration. In addition, the method may include tagging the logged measurement. The method may also include transmitting the tagged logged measurement to the network element.

Abstract: Communication includes transmitting first and second traffic flow packets via a first radio bearer to a second device; detecting that further second traffic flow packets will be transmitted via a second radio bearer to the second device; and transmitting a packet data unit via the first radio bearer to the second device to indicate a switch of the second traffic flow while first traffic flow packets are transmitted via the first radio bearer. Communication may also include receiving first and second traffic flow packets from a first device via a first radio bearer; receiving from the first device a packet data unit indicating that further second traffic flow packets will be received via a second radio bearer while the first traffic flow is received via the first radio bearer; and establishing the second radio bearer between the first and second devices.

Abstract: Improved techniques of intra and inter distributed unit mobility include determining, by a user equipment served by a source cell, whether a target cell belongs to the same distributed unit as the source cell based on information sent by the central unit (control plane) after a connection with the network node has been established. The information sent by the network node includes, for each cell, a group identifier identifying the distributed unit with which that cell is associated. When measurement data provided by the user equipment indicates readiness for a serving cell change to a target cell, the user equipment uses the group identifier to determine whether the target cell belongs to the same distributed unit as the source cell (intra-distributed unit mobility scenario) or a different distributed unit as the source cell (inter-distributed unit mobility scenario).

Abstract: A method includes transmitting packets of first and second traffic subflows via a first radio bearer to a second device; detecting that further packets of the second traffic subflow are to be transmitted via a second radio bearer to the second device; and transmitting a packet data unit via the first radio bearer to the second device, wherein the packet data unit includes an indication of a switch of the second traffic flow. Another method includes receiving from a first device packets of first and second traffic subflows via a first radio bearer; receiving from the first device a packet data unit including an indication that further packets of the second traffic subflow are to be received via a second radio bearer; establishing the second radio bearer between a second device and the first device; and receiving the further packets of the second traffic flow via the second radio bearer.

Abstract: It is provided a method comprising: checking if an indication indicates that a target cell is configured to store concurrently first and second configurations of a terminal, wherein the first configuration is based on a first conditional handover request, and the second configuration data set is based on a second conditional handover request; monitoring if the source cell intends performing a radio reconfiguration of the terminal after the source cell configured the terminal for the first conditional handover; canceling the first conditional handover if the source cell intends performing the radio reconfiguration and the indication does not indicate the concurrently storing; instructing the source cell to request the second conditional handover from the target cell if the source cell intends performing the radio reconfiguration and the indication indicates the concurrently storing.

Abstract: A method includes receiving at an apparatus of a communications device, from a source base station, first configuration information for a conditional handover of the communications device from the source base station to the target base station and subsequently receiving at the apparatus, before the conditional handover has occurred, second configuration information for the conditional handover of the communications device from the source base station to the target base station.

Abstract: Systems, methods, apparatuses, and computer program products of signalling support for protocol data unit (PDU) handling for new radio (NR) to LTE handover are provided. One method includes, when handover from a new radio (NR) network to a long tem evolution (LTE) network is triggered, if a required sequence number (SN) space for the handover is not sufficient in LTE, then storing or queueing the protocol data units (PDUs) from the packet data convergence protocol (PDCP) packet data unit (PDU) transmission buffer of new radio (NR) in the PDCP service data unit (SDU) transmission buffer of LTE.
