摘要： According to certain embodiments, a target network node for communicating with a user equipment (UE) that was previously in communication with a source network node, comprises an interface operably coupled to processing circuitry. The interface is configured to receive a connection resume request from the user equipment, wherein the connection resume request comprises a resume identification associated with the source network node. The processing circuitry is configured to determine that the UE was previously in communication with the source network node. The interface is further configured to transmit the connection resume request to the source network node, receive a radio resource control (RRC) response from the source network node, and forward the RRC response to the UE.

摘要： A method by a first network node in an Integrated Access and Wireless Access Backhaul (IAB) network is provided. The method includes, in the absence of an New Radio (NR) link between the first network node and a second network in the IAB network, sending, to the second network node over Long Term Evolution, LTE, radio, one or more Stream Control Transmission Protocol/Internet Protocol (SCTP/IP) packets. The one or more SCTP/IP packets includes F1-Application Protocol (F1-AP) signaling.

摘要： According to some embodiments, a method for use in a wireless device of acquiring system information associated with a core network comprises receiving system information from a network node. The network node is connected to one or more core networks. The system information includes an indication of a network type (e.g., enhanced packet system (EPS), fifth generation system (5GS), etc.) for each core network. The method further comprises determining a capability of the wireless device for connecting to the plurality of network types, and determining whether to connect to a core network based on the network type and the capability of the wireless device. In particular embodiments, the indication of the network type comprises a list of public land mobile networks (PLMNs) connected to the network node and an indication of network types supported by each PLMN.

摘要： A method for establishing a BH RLC channel between a node and a DU. The method includes a CU detecting (s402) a need to establish the BH RLC channel between the node and the DU; and in response to detecting the need to establish the BH RLC channel, the CU sending (s404) to the DU an AP message requesting the DU to setup the BH RLC channel. The AP message comprises: i) a list identifying one or more BH RLC channels to be setup, wherein the list comprises at least one item containing a BH RLC Channel identifier, ID, information element, IE, containing a BH RLC Channel ID identifying the BH RLC channel, or ii) a DRB ID IE containing the BH RLC Channel ID identifying the BH RLC channel.

摘要： Methods and devices of enabling paging of a wireless communication device. In an aspect, a method of a node configured to provide core network user plane functionality in a communications network is provided to enable paging of a wireless communication device being in an idle state. The method includes receiving an indication that data is to be transmitted in downlink to the wireless communication device, identifying a radio access network control plane function, and sending a downlink data notification comprising an identifier of the wireless communication device and of a core network control plane function configured to provide mobility management where the wireless communication device currently is registered, thereby enabling for the identified radio access network control plane function to forward the download data notification to the identified core network control plane function configured to provide mobility management to enable the identified core network control plane function configured to provide mobility management to page the wireless communication device.

摘要： A method by an integrated access backhaul (IAB) node in a radio network includes generating a delivery status that indicates a status of a data connection, the data connection has a logical interface connection to a central unit (CU) node, the logical interface connection of the data connection is not terminated at the IAB node, and transmitting the delivery status to the CU node. The data connection may be a radio bearer.

摘要： A method performed by a user equipment, UE, for handling communication in a wireless communication network, providing dual connectivity, DC, communication through a master node using a master cell group, MCG, over a first radio interface between the UE and the master node and through a secondary node using a secondary cell group, SCG, over a second radio interface between the UE and the secondary node. The UE detects a failure associated with the SCG and suspends actions associated with the SCG. The UE further performs a reconfiguration of the SCG in case the UE has received a MCG radio resource control, RRC, message comprising SCG configuration, wherein performing the reconfiguration of SCG comprises applying the reconfiguration; and resuming or not resuming the actions associated with the suspended SCG.

摘要： According to an exemplary embodiment a method may be provided to operate a central unit, CU, node that is coupled with first and second distributed unit, DU, nodes. Communication is provided between the CU node and a mobile communication device through the first DU node over a first radio link between the first DU node and the mobile communication device. A message is received from the first DU node informing the CU node that the radio link is temporarily unavailable. Responsive to receiving the message, communication through the first DU node is suspended, wherein configuration of the first DU node to serve the mobile communication device using the first radio link is maintained. While suspending communication through the first DU node, communication may be provided through the second DU node over a second radio link between the second DU node and the mobile communication device.
