    Abstract: The embodiments of the present disclosure provide methods and apparatuses for control of Quality of Service (QoS). A method applied in a base station for control of QoS includes: receiving a Core Network (CN) flow identifier and information on a corresponding QoS parameter of a Packet Data Network (PDN) connection as transmitted from a CN control network element and creating a mapping relation between the CN flow identifier and the corresponding QoS parameter; and utilizing, after determining based on the received information on the QoS parameter of the PDN connection that a radio bearer satisfying a requirement of the QoS parameter exists between a user terminal and the base station, the existing radio bearer satisfying the requirement of the QoS parameter, creating a mapping relation between the existing radio bearer and the CN flow identifier of the PDN connection and transmitting information on the mapping relation to the user terminal.

    Abstract: Method, systems and devices for a master node which is accessed by a user equipment, UE, the UE accessed a source secondary node are provided. The method comprises transmitting, to the target secondary node, an addition request message, receiving, from the target secondary node, an addition request acknowledge message with identification information of a target primary secondary cell in response to the addition request message, determining at least one mobility triggering condition of the target primary secondary cell, and transmitting, to the UE, a secondary node change type message having the at least one mobility triggering condition of the target primary secondary cell, to make the UE perform a handover from the source secondary node to the target secondary node when determining the target primary secondary cell meets at least one of the at least one mobility condition.

    Abstract: Methods and systems for mobility management in non-terrestrial networks are disclosed. In one embodiment, a method performed by a first communication node, includes: during a first time period, communicating with a non-terrestrial communication node utilizing a first communication link, wherein the non-terrestrial communication node provides at least one geographic cell in which a user equipment device (UE) is present during the first time period; during a second time period, communicating with a second communication node utilizing a second communication link, wherein a third communication link is established between the non-terrestrial communication node and the second communication node and the first communication link is no longer utilized during the second time period; and determining to maintain the first communication node as an anchor node for communications between a core network and the UE during both the first and second time periods.
