Abstract: In one illustrative example, a user plane function (UPF) configured for use in a private 5G network of an enterprise may receive, from a user device, a domain name system (DNS) query associated with an application; send, to a DNS server, one or more corresponding DNS queries based on the DNS query; receive, from the DNS server, one or more DNS query responses which include an IP address and metadata including an application identifier for the application; and send, to a control plane function, a message for reporting which includes the application identifier. In response, a dedicated Quality of Service (QoS) Flow may be created for traffic for the application according to a selected QoS policy associated with the application identifier. For obtaining the metadata, the UPF may interact with a DNS server configured with Extension mechanisms for DNS (EDNS) or a DNS as Authoritative Source (DNS-AS) mechanism.

Abstract: Presented herein are techniques to provide data session continuity for parallel data sessions involving a multiple Universal Subscriber Identity Module (MUSIM) user equipment (UE). In one example, a method may include obtaining an indication that session continuity for a first session associated with a first data network and a first USIM of a UE is allowed with respect to a second USIM in which the UE communicates first traffic for the first session via the first USIM. The method may further include determining that second traffic for a second session is to be communicated via the second USIM of the UE and, based on the indication that session continuity for the first session is allowed with respect to the second USIM, providing service information to the UE for the first session to enable the UE to communicate both the first traffic and the second traffic via the second USIM.

Abstract: A control plane function node may be used in a Fifth Generation (5G) Non-Standalone (NSA) architecture having Radio Access Network (RAN) level interworking between a Long-Term Evolution (LTE) RAN and a 5G New Radio (NR). The node obtains usage report data which are based on traffic of a user equipment (UE) via primary and secondary Radio Access Technologies (RATs). The node also obtains secondary RAT usage report data which are based on traffic of the UE via the secondary RAT. The node constructs a message which indicates a request for charging based on the usage report data and the secondary RAT usage report data. In constructing the message, the node populates, in association with a corresponding rating group and usage data of the UE, an identifier of a flow or bearer associated with secondary RAT usage, together with the secondary RAT usage report data.

Abstract: A Network Exposure Function (NEF) relays a trigger from a remote application function to a user device and causes the user device to switch between mutually exclusive network slices. The NEF stores a mapping associating device modes with network slices. The NEF also determines that a user device is operating in a first device mode using a first network slice. The NEF obtains a trigger from the remote application function identifying the user device and a second device mode. The NEF determines that the second device mode is associated with a second network slice that is mutually exclusive to the first network slice. The NEF provides a notification to the user device, causing the user device to end a first data session on the first network slice and to initiate a second data session on the second network slice.

Abstract: In one illustrative example, a user plane (UP) entity for use in a mobile network may receive a data packet from a user equipment (UE) operative to communicate in one or more sessions via a serving base station (BS) (e.g. eNB or gNB) of the mobile network. The UP entity may detect, in a header (e.g. SRH) of the data packet, an identifier indicating a new serving BS or session of the UE. The identifier may be UE- or BS-added data (e.g. iOAM data) that is inserted in the header by the UE or BS. In response, the UP entity may cause a message to be sent to an analytics function (e.g. a NWDAF) to perform analytics for session or flow migration for the UE.

Abstract: In one example, an Access Point (AP) configures a first mapping of a first cellular network connection to a first local access network group, and further configures a second mapping of a second cellular network connection to a second local access network group. The AP determines whether a user device is authorized to use the first cellular network connection or the second cellular network connection. If the user device is authorized to use the first cellular network connection, the AP associates, for the user device, a first user device identifier with the first local access network group. If the user device is authorized to use the second cellular network connection, the AP associates, for the user device, a second user device identifier with the second local access network group.
