Abstract

Systems, methods, devices, and instrumentalities described herein may be used to process and/or provide supplemental QoS rules. A first message may be received from a first network node. The first message may comprises a first Quality of Service (QOS) rule Information Element (IE) and a second QoS rule IE. The first QoS rule IE may be associated with a first QoS rule. The second QoS rule IE may be associated with a second QoS rule. A data packet to be sent to a second network node may be determined. An uplink QoS flow identification (ID) associated with the data packet may be determined based on at least one of the first QoS rule or the second QoS rule. A second message may be sent to a second network node. The second message may comprise the data packet and may indicate the uplink QoS flow ID.

Claims20

Dependent claims

A wireless transmit/receive unit (WTRU), the WTRU comprising:

a processor, wherein the processor is configured to:
receive a first message from a first network node, wherein the first message is a Protocol Data unit (PDU) session modification message that comprises a first Quality of Service (QOS) rule Information Element (IE) and a second QoS rule IE, wherein the first QoS rule IE is associated with a first QoS rule and indicates a first QoS flow ID and a first packet filter, and wherein the second QoS rule IE is associated with a second QoS rule and indicates a second QoS flow ID and a second packet filter;
determine a data packet to be sent to a second network node, wherein the data packet is associated with an application;
determine an uplink (UL) QoS flow identification (ID) associated with the data packet based on at least one of the first QoS rule or the second QoS rule wherein:
on condition that the data packet matches the first packet filter and does not match the second packet filter, the UL QoS flow ID is determined to be the first QoS flow ID, and
on condition that data packet matches the first and second packet filters, the UL QoS flow ID is determined to be the second QoS flow ID;
and
send a second message to a second network node, wherein the second message comprises the data packet and indicates the uplink QoS flow ID.

A first network node, wherein the first network node comprises:

a processor, wherein the processor is configured to:
receive a first message from a second network node, wherein the first message indicates a first policy and charging control (PCC) rule, a second PCC rule, and an indication that the first PCC rule is associated with the second PCC rule;
determine that the second PCC rule is to be applied to a wireless transmit/receive unit (WTRU) that supports a supplemental Quality of Service (QOS) rule feature;
determine a first QoS rule using the first PCC rule;
determine a second QoS rule using the second PCC rule, wherein the second QoS rule is a supplemental QoS rule;
send a second message to the WTRU, wherein the second message comprises a first Quality of Service (QOS) rule Information Element (IE) and a second QoS rule IE, wherein the first QoS rule IE is associated with a first QoS rule and indicates a first QoS flow ID and a first packet filter, and wherein the second QoS rule IE is associated with a second QoS rule and indicates a second QoS flow ID and a second packet filter;
and
send a third message to a third network node, wherein the third message indicates that the WTRU supports the supplemental QoS rule feature.

A method, performed by a wireless transmit/receive unit (WTRU), the method comprising:

receiving a first message from a first network node, wherein the first message is a Protocol Data unit (PDU) session modification message that comprises a first Quality of Service (QOS) rule Information Element (IE) and a second QoS rule IE, wherein the first QoS rule IE is associated with a first QoS rule and indicates a first QoS flow ID and a first packet filter, and wherein the second QoS rule IE is associated with a second QoS rule and indicates a second QoS flow ID and a second packet filter;
determining a data packet to be sent to a second network node, wherein the data packet is associated with an application;
determining an uplink (UL) QoS flow identification (ID) associated with the data packet based on at least one of the first QoS rule or the second QoS rule wherein:
on condition that the data packet matches the first packet filter and does not match the second packet filter, the UL QoS flow ID is determined to be the first QoS flow ID, and
on condition that data packet matches the first and second packet filters, the UL QoS flow ID is determined to be the second QoS flow ID;
and
sending a second message to a second network node, wherein the second message comprises the data packet and indicates the uplink QoS flow ID.
