Abstract

Systems, methods, devices, and instrumentalities are described herein related to using an application identifier to identify an application instance running on a WTRU and providing special QoS treatment per application instance. A device (e.g., an enabler server) may include a processor configured to perform one or more actions. The device may receive a first message. The first message may include an application instance identifier and state information. The device may send, to a first network node, a second message. The second message may include the application instance identifier and the state information. The device may receive, from a second network node, a third message. The third message may include the application instance identifier and a change of state request notification. The device may receive a change of state notification. The device may send, to the second network node, a fourth message.

Description

BACKGROUND Mobile communications using wireless communication continue to evolve. A fifth generation may be referred to as 5G. A previous (legacy) generation of mobile communication for example, may be fourth generation (4G) long term evolution (LTE). SUMMARY Systems, methods, devices, and instrumentalities are described herein related to using an application identifier to identify an application instance running on a WTRU and providing special quality of service (QoS) treatment per application instance. A device (e.g., an enabler server) may include a processor configured to perform one or more actions. The device may receive a first message. The first message may include an application instance identifier and state information. The device may send, to a first network node, a second message. The second message may include the application instance identifier and the state information. The device may receive, from a second network node, a third message. The third message may include the application instance identifier and a change of state request notification. The device may receive a change of state notification. The device may send, to the second network node, a fourth message. In examples, the second message may be a Non Access Stratum (NAS) mobility management (NAS-MM) or an NAS session management (NAS-SM) message. The state information may indicate whether the application is active or inactive. The third message may be a packet data unit (PDU) session modification message. The third message may indicate that the application instance identifier is authorized to be associated with the WTRU. The third message may include QoS rules for a flow associated with the traffic of the application. The fourth message may be a NAS-SM message. The WTRU may be a mobile termination (MT) part of the WTRU, and the change of state notification may be received from a terminal equipment (TE) part of the WTRU. The first message may be received from a hosted application in the TE part of the WTRU. A device (e.g., an enabler server) may include a processor configured to perform one or more actions. The device may receive a first message. The first message may include an application instance identifier, an indication associated with a state of an application, and a notification that the application instance identifier is associated with a PDU session. The device may send, to a second network node, a second message. The second message may include a request to associate the application instance identifier with the PDU session. The second message may include the indication associated with the state of the application. The device may receive, from a third network node, an indication of whether the application instance identifier is authorized to be associated with the PDU session. The device may receive, from the third network node, updated policy and charging control (PCC) rules. The updated PCC rules may be based on the application instance identifier. The device may send, to a wireless transmit/receive unit (WTRU), a third message. The third message may include the application instance identifier and a change of state request notification. The device may receive, from the WTRU, a fourth message. The fourth message may notify the first network node of a change of state of the application. The fourth message may include traffic associated with the application. In examples, the second message may include an identity of the third network node that services the PDU session. The third message may be a PDU session modification message. The third message may indicate that the application instance identifier is authorized to be associated with the WTRU. The third message may include QoS rules for a flow associated with the traffic of the application. The fourth message may be a NAS-SM message. The device may update a QoS configuration of the PDU session based on the fourth message.
