  • Handling Application Protocol Identity for a UE-Associated Logical Connection
    Publication number: 20210007175
    Abstract: A network node (300a) receives, over an interface between the network node (300a) and a further network node (300b), a message comprising paired user equipment (UE) identifiers for UE identification over the interface to the network node (300a) and further network node (300b), respectively. Responsive to determining that the identifier for UE identification to the network node (300a) uniquely identifies a UE (150) to the network node (300a), the network node (300a) validates the message irrespective of whether the identifier for UE identification to the further network node (300b) uniquely identifies the UE (150) to the further network node(300b).

  • HANDLING QoS MOBILITY AND DUAL CONNECTIVITY IN NR
    Publication number: 20200404732
    Abstract: Systems and methods are provided herein for handling Quality of Service (QoS) mobility and dual connectivity. In some embodiments, a method of operation of a network node in a cellular communications network includes deciding to split an existing Protocol Data Unit (PDU) session that includes a current uplink tunnel information; and setting up resources for the split PDU session. In this way, it may be possible to support QoS mobility in the different tunnel during dual connectivity. In some embodiments, the network node is a Master Next Generation—Radio Access Network (NG-RAN) node, and setting up resources for the split PDU session includes sending an S-Node Addition/Modification Request including the current uplink tunnel information for the split PDU session to a Secondary NG-RAN node in the cellular communications network; and receiving a newly added additional downlink tunnel information from the Secondary NG-RAN node.

  • Notification Control Over RAN Interfaces
    Publication number: 20200280872
    Abstract: According to a first exemplary embodiment a method is performed by a first network node for monitoring the QoS of a flow. A session setup message comprising a QoS configuration for the flow and an indication that the flow is subject to QoS notification control is received (1710) from a core network node. Based on the QoS configuration, radio resources to be used for the flow are determined (1720) and a resource setup message comprising an identification of the radio resources and an indication that the flow and/or the radio resources are subject to QoS notification control is sent (1730) to a second network node. A first notification control indication that the QoS configuration the flow and/or the radio resources cannot be fulfilled is received (1740) from the second network node and a resource notification message indicating that the QoS configuration for the flow cannot be fulfilled is sent (1750) to the core network node.

  • METHOD FOR FEEDBACK OF STREAMING SESSION
    Publication number: 20200280498
    Abstract: A method of operating a UE to provide feedback on a streaming session. The method includes determining when a streaming session used by an application layer of the UE is being started and/or ended. Responsive to the determination, the method transmits an indication to a RAN that the streaming session is being started and/or ended. A corresponding method of operating a network node is provided to control reporting relating to streaming sessions of UEs. The method by the network node receives an indication from an UE that a streaming session is being started and/or ended, and controls whether a Quality of Experience (QoE) configuration file is sent to the UE responsive to the indication.

    Publication number: 20200259896
    Abstract: Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

  • Methods, Network Node and Wireless Device for Discontinuous Transmission
    Publication number: 20200120744
    Abstract: A network node (200), a wireless device (202) and methods therein, for handling discontinuous transmission, DTX, in a communication using multiple uplink carriers. The communication involves a primary uplink carrier using a first Transmission Time Interval, TTI and a secondary uplink carrier using a second TTI which is different than the first TTI. Values of DTX parameters defined for only one of the first and second TTIs are selected (2:4) for the communication, and the wireless device (202) is instructed (2:7) to use the selected values of DTX parameters for transmission on both the primary uplink carrier and the secondary uplink carrier. Thereby, misalignment of DTX cycles employed on the two uplink carriers can be avoided or reduced.

  • Method and Network Nodes to Manage QoE Measurement Collection During Relocation or Handover
    Publication number: 20200092762
    Abstract: Quality of Experience (QoE) Measurement collection is continued from a source network node (200) servicing a terminal (210) to a target network node (200) following a relocation or handover of the terminal (210). When the source network node (200) is preparing for the relocation, e.g., SRNS Relocation, Intra-RAT handover (e.g., X2 handover), or Inter-RAT handover, for a terminal (210) which has QoE Measurement configured, the trace session information, which has been received by the source network node from a Measurement Initiating node (200), is sent (12) from the source network node (200) to the target network node (200). The target network node (200) provides (14, 26) information about the handling of the ongoing Qo E measurement to the source network node (200), e.g., whether the QoE measurement is to be continued or terminated. The source network node (200) updates to the Measurement Initiating node (200) that the trace session is transferred to the target network node (200).
