Abstract: Enabling granular control of application flows with Differentiated Services Code Point (DSCP) identifiers with User Equipment Route Selection Policy (URSP) traffic classification in a wireless communications system. A UE or a Fixed Wireless Consumer Premises Equipment (FW CPE) can receive URSP rules from a core network node, where the URSP rules also include DSCP values as URSP traffic descriptors. Then, application flows that include DSCP values from the UE or from devices connected to the FW CPE can then be mapped to Protocol Data Unit (PDU) sessions established with a Communication Service Provider (CSP). The data can then be transmitted by the UE or FW CPE to the CSP via the PDU session selected based on the DSCP value.

Abstract: Enabling granular control of application flows of an Enterprise application while providing User Equipment Route Selection Policy (URSP) traffic category mapping. Application flows of the Enterprise application can then be mapped to enterprise connectivity services that can be mapped to respective Protocol Data Unit (PDU) sessions established with a Communication Service Provider (CSP). By providing Enterprise application identifiers and URSP traffic category information in the work profiles administered by the Enterprise Information Technology (IT) Administration, application flows can thus be prioritized or handled based on the determined Quality of Service (QOS) level of each application flow, and not on a per application-basis.

Abstract: Multiple Virtual Private Network (VPN) solution, wherein each VPN can be associated with a specific Quality of Service (QoS) level in the Communication Service Provider (CSP) network which is achieved by a 2 step User Equipment Route Selection Policy (URSP) traffic category mapping where first, application flows are mapped to the VPNs based on a URSP traffic category, and then second, each VPN is mapped to the CSP Protocol Data Unit (PDU) Sessions based on the URSP traffic category. Application flows can thus be prioritized or handled based on the determined QoS level, but the application flows can be encrypted between the UE and an application server.

Abstract: A method for marking a Quality of Service (QOS) for packet traffic on a connection between a User Equipment (UE) and a destination device. The method provides for receiving, from the UE, an Uplink (UL) carrier traffic destined for the destination device, the UL carrier traffic including a QoS parameter to indicate a class of QoS applied to the UL carrier traffic, associating the QoS parameter with routing information carried in the UL carrier traffic and storing the QoS parameter linked to the routing information in a data structure. The method further provides for receiving Downlink (DL) carrier traffic from the destination device, wherein the DL carrier traffic includes the routing information, and associating the routing information carried in the DL carrier traffic with the routing information stored in the data structure to retrieve the QoS parameter to mark QoS for the DL carrier traffic.

Abstract: This disclosure presents a method for provisioning a User Equipment (UE) policy to a UE in the Extended Protocol Configuration Options (ePCO). The method involves provisioning the UE policy to a user terminal via an ePCO, where the UE policy is included in a UE policy container. The UE policy is transmitted from a first network node to the user terminal, where it is received and included in the UE policy container and the ePCO. The method also involves transmitting the UE policy from the first network node to a second network node, where it is included in a UE policy container and the ePCO, before being transmitted to the user terminal.

The method comprises receiving a triggering message, and based at least on receiving the triggering message, transmitting towards a user equipment, UE, a message related to a Protocol Data Unit, PDU, session. The message related to the PDU session indicates any one or more of the followings: i) that a particular functionality is applied to a part of traffic or all traffic in the PDU session; ii) that 3rd Generation Partnership Project, 3GPP, access is needed for using a particular application or all applications mapped into the PDU session; iii) that a reconnection to 5G System, 5GS, is needed for using a particular application or all applications mapped into the PDU session; or iv) that non-3GPP access is allowed for using a particular application or all applications mapped into the PDU session only if one or more conditions are satisfied.

Abstract: A Session Management Function, SMF, (650) determines that a first data path for a Packet Data Unit, PDU, session between an application client (611) and a first edge application server, EAS, (681) should be relocated from a first local PDU session anchor, PSA, (631) and a first uplink classifier and branching point, ULCL/BP, (621) to a second PSA (632) and a second ULCL/BP (622).
