  • Patent number: 10805856
    Abstract: A central unit (300A) and a first distributed unit (300B) of a first network node (300) and methods therein, for handling a communication with a wireless device (302) in a wireless network. The central unit (300A) sends an indication to the first distributed unit (300B) to indicate whether a current procedure for the wireless device is an inter-central unit procedure or an intra-central unit procedure. The first distributed unit (300B) is thereby able to decide whether to send information about the communication to the central unit via a user plane or via a control plane, based on a reduced amount of signalling including the indication.

  • Patent number: 10798677
    Abstract: In case of an UE in an inactive state (RRC disconnected but Core Network connected), the Core Network cannot page the UE because this one is formally connected. The UE is therefore paged at RAN-level. In detail, the first Base Station that receives downlink data or control signalling for the UE, pages the UE. If the UE does not reply, the first Base Station requests second Base Stations to page the UE. If not found the request is enlarged from the second BS to further Base stations and so on until either the UE is found or a maximum number of hops is reached. The Base Stations trace then backwards the information that the UE has been paged until the first BS.

  • Publication number: 20200314782
    Abstract: In one aspect, a network access node requests, via a service request, a synchronization service from a network node, receives synchronization source information corresponding to the synchronization service and uses the synchronization source information to detect and measure signals from a synchronization source node. The network access node stores signal identifiers corresponding to one or more of the measured signals as neighbor information and subsequently performs signal measurements on signals from the synchronization source node, based on the stored signal identifiers, and uses the signal measurements to perform a mobility operation.

  • Publication number: 20200305235
    Abstract: Embodiments include methods, performed by a first radio network node (RNN) in a wireless network, to establish a communications interface with a second RNN in the wireless network. Such methods include receiving, from a third RNN in the wireless network, a Transport Network Layer (TNL) address associated with the second RNN. The first and third RNNs are configured for wireless communication with wireless devices via an E-UTRA radio access technology (RAT), and the second RNN is configured for wireless communication via an NR RAT. The third RNN can be a proxy node for discovery of TNL addresses associated with a plurality RNNs configured for wireless communication via the NR RAT. Such methods include establishing the communications interface with the second RNN based on the TNL address received from the third RNN. Other embodiments include complementary methods performed by a second RNN, and RNNs configured to perform such methods.

  • 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.

  • Publication number: 20200163146
    Abstract: Systems, methods, and apparatus for operating RAN and CN nodes are disclosed. An example method of operating a RAN node includes receiving, from a CN node, a PDU for a wireless device that is in an inactive state. The RAN node pages the wireless device in response to receiving the PDU from the CN node. The RAN node sends a non-delivery message to the CN node in response to failure of the paging for the wireless device, where the non-delivery message includes an indication that the wireless device is in the inactive state. An example method of operating a CN node includes the CN node sending a PDU for a wireless device to a RAN node. The CN node then receives a non-delivery message from the RAN node, where the non-delivery message includes an indication that the wireless device is in an inactive state.
