Abstract: Presented herein are efficient techniques in which an application function (AF) session is established between a first policy control function (PCF) in a standalone non-public network (SNPN) domain and a second PCF in a Public Land Mobile Network (PLMN) domain, wherein a user equipment has a first session with the SNPN domain, the AF session is established for a second session of the user equipment with the PLMN domain, and the AF session is bound to the first session. The second PCF obtains an indication of a data flow initiated for the user equipment for the second session within the PLMN domain and determines flow information associated with the data flow. The second PCF transmits to the first PCF the flow information associated with the data flow for creating the data flow in the SNPN domain.

Abstract: Systems and methods are provided for utilizing an asynchronous report feature when a time or volume reporting trigger is unavailable. The systems and method can include receiving node level capabilities from at least one of a plurality of user plane functions, receiving an asynchronous report from the at least one of the plurality of user plane functions, determining an absence of a reporting trigger based on charging information associated with a policy control function and trigger information associated with a charging function, selecting a user plane function from the plurality of user plane functions based on the asynchronous report, and generating a usage reporting rule without the reporting trigger to be provided to the user plane function from the plurality of user plane functions.

Abstract: The present technology is directed to establishing a connection between a client device within a 2G or 3G network and 5G core through an interworking function. The present technology can perform establishing a Gn-4G interworking function (IWF) between a client access network and a packet anchor network and performing one or more network functions through the Gn-4G IWF in providing a client of the client access network access to network services through the packet anchor network. The one or more network functions appear as one or more Gateway GPRS Support Node (GGSN) functions from the client access network (e.g., 2G or 3G network). The one or more network functions concurrently appear as one or more S4 Serving GPRS Support Node (SGSN) functions from the packet anchor network (e.g., 4G or 5G network).
