Abstract: The present technology is generally directed to optimizing a non-3GPP untrusted Wi-Fi to 5G system handover followed by Evolved Packet System (EPS) fallback, more specifically, to delaying removal of the Wi-Fi session resources and creating a voice flow as part of the EPS fallback. The present technology can receive a request for an EPS fallback from a mobile device for a handover to a 5G network while the mobile device is in communication over non-3GPP access network, maintain one or more resources of the non-3GPP access network during data path switching from the non-3GPP access network to the 5G network, generate a list of EPS bearer identifiers to transmit to an access and mobility management function (AMF), wherein the list of EPS bearer identifiers is associated with a voice flow to transfer the one or more resources of the non-3GPP access network as part of the handover from the non-3GPP access network to the 5G network, and transmit the list of EPS bearer identifiers to a mobility management entity (MME).

Abstract: In one example, a session management function entity is configured to obtain an indication of a backup resource usage quota associated with a rating group of a user session for a user equipment configured to communicate via a mobile core network. The rating group is subject to online charging. The session management function entity determines that a charging function entity configured to provide an indication of a primary resource usage quota associated with the rating group is unreachable. In response to determining that the charging function entity is unreachable, the session management function entity allocates the backup resource usage quota associated with the rating group while the charging function entity is unreachable.

Abstract: At least one offline usage reporting rule is instantiated at a user plane element of the telecommunications network, wherein the usage reporting rule indicates at least one trigger condition. The user plane element detects an occurrence of the at least one trigger condition in traffic processed by the user plane element and, in response, generates and temporarily stores a first usage report. Subsequently, the user plane element detects an occurrence of an immediate reporting condition and, in response to detecting of the occurrence of the immediate reporting condition, sends the first usage report to a control plane element.

Abstract: Method for reducing interface traffic and memory of a session management function (SMF) establishes an exchange of preservation between the SMF and a policy control function (PCF) via an interface for a first session by a first subscriber in a wireless network. The method also includes receiving, by the SMF from the PCF, the preservation including definitions of common data and a preserve indication for the definitions of the common data. The definitions of the common data are used for a plurality of sessions following the first session by a plurality of subscribers. The method also includes storing, by the SMF, the definitions of common data; establishing an exchange of preservation between the SMF and the PCF for one of the plurality of sessions by a second subscriber; and receiving, by the SMF, references to the common data without the definitions of the common data.

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.
