Systems, methods, and instrumentalities are disclosed for determining corresponding quality of service (QoS) information that are utilized in a first network for different data associated with a second network. The data may include control plane data and user plane data. A wireless transmit/receive unit (WTRU) may send a request to the first network to establish a first session with the first network for transmission of the data associated with a second network. The WTRU may receive one or more QoS mapping rules. The one or more QoS mapping rules may include information for mapping a first QoS indication to a packet comprising control plane data associated with the second network and information for mapping a second QoS indication to a packet comprising user plane data associated with the second network. The WTRU may use the one or more QoS mapping rules to determine a QoS indication for a packet.

A method for data transmission, performed by a first device, such as a User Equipment (UE) or a User Plane Function (UPF) network element, is provided. The method includes: obtaining transmission data; determining, according to network type information included in an extended Ethernet packet filter set, that the transmission data is Time Sensitive Communication (TSC) data; determining a transmission characteristic of the TSC data according to the extended Ethernet packet filter set; and mapping, according to the transmission characteristic, the TSC data to a Quality of Service (QoS) flow corresponding to the transmission characteristic for transmission; and transmitting the TSC data based on the QoS flow.

A Virtual Endpoint and a method therein for enabling end-to-end connectivity between a wireless communication network and a wired communication network are disclosed. A Virtual Endpoint is implemented in the wireless communication network and certain user and control plane features used in the wired communication network are implemented in the VEP. The VEP maps data traffic between a device in the wireless communication network and a device in the wired communication network based on Quality-of-Service (QoS) and performs required actions defined by the features used in the wired communication network.

There is provided mechanisms for transmission of packets over a TSN aware network. A method is performed by a network node. The method includes obtaining a traffic flow of packets from a non-TSN aware network interface. The method includes extracting, from the packets and at above OSI protocol layer 2, information indicative of which traffic class the traffic flow belongs to. The method includes mapping the traffic class to a TSN traffic class or priority. The method includes associating the packets with an indicator of the TSN traffic class or priority. The method includes providing the traffic flow of packets, including the indicator, to a TSN aware network interface for transmission of the packets over the TSN aware network.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network controller of a wireless communication system may receive a time-sensitive network (TSN) traffic configuration that indicates a duration of a gate open state for a TSN traffic flow and a periodicity with which the gate open state occurs; configure one or more quality of service (QoS) parameters, associated with the wireless communication system, for a QoS flow that is to carry the TSN traffic flow, wherein the one or more QoS parameters are configured based at least in part on one or more TSN capability parameters associated with the network controller and at least one of the duration of the gate open state or the periodicity; and transmit the one or more QoS parameters to a base station of the wireless communication system. Numerous other aspects are provided.

A method for optimizing group communication services, the method including determining a current location and an assigned home server for one or more devices associated with each of a plurality of group members, determining whether the one or more devices of the plurality of group members has moved to a visiting location, wherein the visiting location is a location outside of locations associated with the assigned home server based on the current location and assigned home server for the one or more devices, and assigning a group control application server associated with the visiting location to the to the one or more devices to serve as the assigned home server.

There is provided mechanisms for quality of service differentiation between network slices. A method is performed by a prioritization entity. The method comprises obtaining relative priority values for the network slices from a network entity. The method comprises providing an access network entity with a relative priority value for a protocol data unit (PDU) flow as given by the relative priority value for the network slice used by that PDU flow, thereby causing differentiation of the quality of service for the network slices.
