摘要： A method and system for group handover is provided. In an embodiment, a method in a network component for group handover in a wireless network includes receiving, at the network component, a mobility command from a target base station. The method also includes processing, with the network component, the mobility command in a packet data convergence protocol (PDCP) layer of a context for a remote user equipment (UE) to generate a PDCP Protocol Data Unit (PDU). The method also includes encapsulating the PDCP PDU as a field in a radio resource control (RRC) message to the relay UE.

摘要： A network device configured for operating as a target node in a network comprising one or more user devices and one or more further network devices. The network device is configured to transmit a radio resource control, RRC, downlink message, to a user device of the one or more user devices when the user device is connected to the network device. The RRC downlink message comprises configuration data for the user device applicable for executing a small data transmission SDT, when the user device is in an inactive mode. Corresponding further devices and a method are also provided.

摘要： A user device having a Non-Access-Stratum NAS layer and a radio resource control RRC layer, where the user device is configured to send an indication message from the NAS layer to the RRC layer. The indication message indicates that one or more NAS messages are to be passed to the RRC layer for transmission to a core network node and further specifies how the one or more NAS message are to be transmitted. In response to receiving the indication at the RRC layer, the RRC layer adopts a connection state according to the indication.
