Abstract:
1. A method to promote connectivity between a user agent (UA) and a packet data network (PDN), comprising: determining a quality of service class identifier (QCI) associated with a service data flow, the QCI having a scalar value indicative of a current set of defined values for a set of respective QoS characteristics for the service data flow; determining a change from the current set of defined values for the set of respective QoS characteristics for the service data flow; determining a QCI extension that includes a plurality of bits, wherein a combination of values of the plurality of bits is indicative of the change; and sending a request to apply a service data flow treatment for the service data flow, the request comprising the QCI indicative of the current set of defined values and the QCI extension indicative of the change, wherein the QCI comprises four bits or more, the QCI extension comprises four bits or more, and wherein the change indicated by the QCI extension is an increase or decrease of at least one defined value of the current set for at least one respective QoS characteristic, the at least one respective QoS characteristic comprising a resource type, a priority, a packet delay budget, and a packet error loss rate, and wherein, when the QCI extension comprises ‘1111’ binary, the defined value of the priority in the current set is increased by a first default value, the defined value of the packet error loss rate in the current set is increased by a second default value, and the defined value of the packet delay budget in the current set is increased by a third default value, all relative to the corresponding QoS characteristics defined by the scalar QCI.
