摘要： Methods and apparatus are disclosed herein for providing reporting of Secondary Node (SN) change and Secondary Cell Group (SCG) failure. In one embodiment, a method performed by a UE comprises receiving an indication associated with an SN change or a Primary Serving Cell (PSCell) change and indicating a node that initiated the SN change/PSCell change; declaring an SCG failure; and transmitting, to a network node, an indication of the node that initiated the SN change/PSCell change. In another embodiment, a method performed by a first network node comprises transmitting, to a UE, an RRCReconfiguration message associated with an SN change or PSCell change and comprising an indication indicating a node that initiated the SN change/PSCell change; receiving, from the UE, information regarding an SCG failure; determining a second network node based on the information; and transmitting the information to the second network node.

摘要： A method in a network node including a gNB-Distributed Unit (DU) logical node and a gNB-Central Unit (CU) logical node for determining admission of a user equipment (UE) includes the steps: the gNB-DU receiving a connection request from a UE; in response to a determination that the gNB-DU is not able to serve the UE, sending an initial uplink radio resource control (UL RRC) message that does not include a configuration for signaling radio bearer 1 (SRB1) from the gNB-DU to the gNB-CU; in response to receiving, at the gNB-CU, the UL RRC message that does not include the configuration for SRB1, responding to the gNB-DU with a radio resource control (RRC) ConnectionReject message; and transmitting the RRC ConnectionReject message from the gNB-DU to the UE to reject the UE.

摘要： Methods and systems are described for indicating mobility history information (MHI) capability of a user equipment (UE) in a communication system. During a handover procedure, a target cell or node may not be aware of the MHI capability of the UE. In certain embodiments, a source network node can indicate the UE's MHI capability in a handover message. In certain embodiments the UE can indicate its MHI capability to the target node when it realizes the source node has not fetched the MHI.

摘要： According to an embodiment, a method is performed by a control unit (CU) of a network node. The control unit receives a request message indicating that a wireless device has requested a connection with the network node. The request message is received by the 5 CU via a distribution unit (DU) of the network node. The control unit determines whether to admit or reject the requested connection. In response to determining to reject the requested connection, the control unit transmits a rejection message to the wireless device via the DU. The rejection message indicates that the requested connection has been rejected. The DU may determine that the requested connection has been rejected based on the rejection message or 0 another rejection indication sent by the CU. The DU deallocates resources associated with the rejected wireless device and reallocates the resources.

摘要： The invention relates to methods and devices of distributing data content in an Information Centric Networking (ICN) network where access of a wireless communication device publishing the data content is transferred from a source access point serving wireless communication device to a target access point. In an aspect of the invention, a method performed by a source access point (102) is provided for distributing data content in an ICN network (112) where access of a wireless communication device (103) publishing the data content is transferred from the source access point (102) serving the wireless communication device (103) to a target access point (104). The method comprises notifying (S101) the target access point (104) of an ICN routing identifier associated with the wireless communication device (103) providing the requested data content, notifying (S103) the target access point (104) of any pending ICN requests directed to the wireless communication device (103) such that that any data content provided by the wireless communication device (103) to the target access point (104) is forwarded to the original requester, and updating (S105) an ICN Forwarding Information Base, FIB, at the source access point (102) such that any ICN request directed to the wireless communication device (103) is forwarded to the target access point (104).

摘要： 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.
