    Abstract: An apparatus including at least one processor and at least one memory including computer program code. The at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to receive, from a serving access node, a downlink radio resource control message including reference time information for a clock provided by the serving access node and traceability information for enabling traceability of the clock to a reference time standard. The traceability information includes at least information on a clock class indicative of a current status of the clock provided by the serving access node.

    Abstract: Various example embodiments provide efficient jitter control by means of a hybrid automatic repeat request (HARQ) process. Abase station may transmit to a UE a forwarding time parameter for data packet(s) associated with a HARQ process. The UE 110 may store the data packet(s) in a HARQ buffer and determine to hold the data packet(s) in the HARQ buffer until a delivery time determined based on the forwarding time parameter. Once the delivery time has been reached, the UE may forward the data packets to higher protocol layers. This enables efficient jitter control of a data packet flow. Apparatuses, methods, and computer programs are disclosed.

    Abstract: An apparatus which is able to communicate based on at least two communication methods, wherein each communication method is configured to communicate with access networks by using at least one subflow, acquires (S41) information from at least one of the communication methods for at least one of the subflows and provides (S42) the information to a subflow control entity at a higher layer of the apparatus. Based on the information, the subflow control entity evaluates (S43) whether a change will occur in the at least one of the subflows. In case the change is evaluated to occur in the at least one of the subflows, the subflow control entity evaluates (S44) when the change will occur, and evaluates (S45) whether the change evaluated to occur impacts a specific requirement of delivering packets by using the at least one of the subflows. In case the change is evaluated to impact the specific requirement, the subflow control entity changes (S46) usage of the subflows for delivering packets.

    Abstract: Systems, methods, and software of directly connecting a SIM-less device with a cellular network. In one embodiment, User Equipment (UE) includes a Subscriber Identity Module (SIM) provisioned with a plurality of subscription profiles for subscriptions to the cellular network. The UE establishes a direct communication with a SIM-less device that does not have a subscription with the cellular network. The UE selects one of the subscriptions provisioned in the SIM as a temporary subscription assigned to the SIM-less device to allow the SIM-less device to establish a direct connection with the cellular network using the temporary subscription, and transmits a message to the SIM-less device via the direct communication containing subscription credentials for the temporary subscription. The SIM-less device may therefore register with the cellular network using the subscription credentials provided by the UE, and establish a direct connection with the cellular network using the temporary subscription.

    Abstract: Disclosed is a method comprising estimating a time synchronization accuracy associated with a plurality of base stations comprising at least a first base station and a second base station based at least partly on one or more uncertainty factors determined by the terminal device, selecting the second base station from the plurality of base stations by comparing the estimated time synchronization accuracy associated with the plurality of base stations, and synchronizing a clock based on the selected second base station.
