A network control node configured to connect a wireless transmit/receive unit, WTRU, to a network slice in a network, the network node comprising: a processor configured to: receive service information associated with a service being requested by the WTRU; determine, based on the received service information and subscription information for the WTRU, slice information associated with a network slice to serve the WTRU, wherein the slice information comprises one or more of an identifier of the network slice, priority of the network slice, a service class served by the network slice, a target device class, a quality of service, QoS, target, mobility support, security service, charging information, or performance information; and determine whether the network control node or another network control node should service the WTRU for accessing the network slice, wherein: on condition that the network control node determines that the network control node should service the WTRU for accessing the network slice, the network control node provides at least one network service associated with the network slice to the WTRU, or on condition that the network control node determines that another network control node should service the WTRU for accessing the network slice, the network control node sends a request to the another network control node that indicates that the another network control node should service the WTRU for accessing the network slice. receive service information associated with a service being requested by the WTRU; determine, based on the received service information and subscription information for the WTRU, slice information associated with a network slice to serve the WTRU, wherein the slice information comprises one or more of an identifier of the network slice, priority of the network slice, a service class served by the network slice, a target device class, a quality of service, QoS, target, mobility support, security service, charging information, or performance information; and determine whether the network control node or another network control node should service the WTRU for accessing the network slice, wherein: on condition that the network control node determines that the network control node should service the WTRU for accessing the network slice, the network control node provides at least one network service associated with the network slice to the WTRU, or on condition that the network control node determines that another network control node should service the WTRU for accessing the network slice, the network control node sends a request to the another network control node that indicates that the another network control node should service the WTRU for accessing the network slice. on condition that the network control node determines that the network control node should service the WTRU for accessing the network slice, the network control node provides at least one network service associated with the network slice to the WTRU, or on condition that the network control node determines that another network control node should service the WTRU for accessing the network slice, the network control node sends a request to the another network control node that indicates that the another network control node should service the WTRU for accessing the network slice.
