Abstract: A system uses deep packet inspection and a services policy database to select policy control functions based on services associated with a packet data session rather than an access point name or data network name. As a packet data session is initiated, a system management function (SMF) determines a service associated with the session and routes a policy request to one of several policy control functions (PCF or PCRF) depending on the service. Policies specific to the service may be chosen and enforced at the selected PCF/PCRF.

Abstract: Systems, devices, and techniques described herein relate to prioritizing access by first user equipment (UEs) connected to a first radio access technology (RAT) type over access by second UEs connected to a second RAT type responsive to a failure of a core network node. A node of the core network, such as a session management node, may determine that another node of the core network has failed based on a negative response or no response from that other node. The node may then prioritize access based on RAT types of requesting UEs.

Abstract: A telecommunication system can include a network flow controller (e.g., SMF) and a network-charging node (e.g., CHF). The flow controller can generate a first charging-event record associated with a network session. The flow controller can detect an outage at least partly by determining that no network-charging node is available to receive the first charging-event record and, in response, mark the first charging-event record to provide a first marked charging-event record. The flow controller can store the first marked charging-event record in a buffer. After the marking, the flow controller can determine that a network-charging node is available to receive the first marked charging-event record, and, in response, send the first marked charging-event record to the network-charging node. The network-charging node can determine a charging-data record indicating occurrence of an event during the outage.

Abstract: A method and system for content filtering. A network repository function unit registers a session management function unit. The session management function unit initiates a session in response to a session request from a user equipment. The session management function unit accesses a subscriber profile stored by a data management unit, and the subscriber profile includes one or more content filtering settings. In response to the session being established, the session management function unit is configured to determine data packets for the user equipment to be filtered based on the one or more content filtering settings. Absent triggering an instruction to be sent via a Gx interface, an access and mobility management function (AMF) unit is configured to select the session management function unit in compliance with the one or more content filtering settings for filtering the data packets for the user equipment.

Abstract: In a cellular system having both 4th-Generation (4G) and 5th-Generation (5G) cellular networks, cellular device sends a Session Initiation Protocol (SIP) INVITE message to initiate a voice call. The message is received and acted upon by a Proxy-Call Session Control Function (P-CSCF) of an IP Multimedia Subsystem (IMS). Cellular devices that support 5G services are configured to include an information element (IE) in the SIP INVITE message to indicate support for 5G services. When responding to a SIP INVITE message, the P-CSCF determines whether the SIP INVITE message includes such an IE. If the SIP INVITE message contains an IE indicating 5G support, the P-CSCF sends an Authorization Authentication Request (AAR) message to a 5G Policy Control Function (PCF) to initiate a 5G dedicated bearer. Otherwise, the P-CSCF sends the AAR to a 4G Policy and Charging Rules Function (PCRF) to initiate a 4G dedicated bearer.

Abstract: A system, e.g., associated with a telecommunications network, includes first and second registry devices. In some examples, the first registry device receives a registration message. The second registry device receives a query specifying a type (NFType) of a network function and forwards the query to the first registry device based at least in part on the NFType. The first registry device responds, and the second registry device forwards the response. In some examples, the query specifies a service class and the second registry device forwards the query based at least in part on the service class. In some examples, the first registry device sends an indication of the registration to the second registry device, and the second registry device responds to the query based at least in part on the received indication and on at least one of an NFType or a service class of the query.

Abstract: Systems, methods, and devices can be utilized to provide charging function (CHF) fallback in a 5th Generation Core (5GC). An example method is performed by a fail-open function (FOF), and includes receiving, from the CHF, information corresponding to a subscriber of a network. The information is stored in a database. Further, the example method includes receiving, from the CHF or a connected function, a request corresponding to the subscriber. The connected function is a session management function (SMF) and/or a policy control function (PCF). Based on the request, the information stored in the database is at least one of accessed or modified. Based on performing at least one of accessing or modifying the information stored in the database, a response is generated and transmitted to the CHF or the connected function.

Abstract: Bandwidth-dependent selection of a packet routing node (e.g., user plane function (UPF) for 5G, packet data network gateway user plane function (PGW-U) for 4G) includes determining, for each of a plurality of packet routing nodes, a bandwidth capacity to an access network (e.g., a radio access node); receiving a request for a data traffic session; determining whether the data traffic session comprises a bandwidth priority; identifying a subset of the plurality of packet routing nodes having a higher bandwidth capacity than others of the plurality (e.g., the packet routing node having the highest capacity, or the top percentage); based on at least determining that the data traffic session comprises a bandwidth priority data traffic session, selecting a packet routing node for the data traffic session from the subset; and establishing the data traffic session through the selected packet routing node.

Abstract: A method for selecting a user plane function when a user equipment (UE) attaches to a wireless communication network may include determining a data throughput limit associated with the UE, identifying a first user plane function having a first data throughput capacity, and identifying a second user plane function having a second data throughput capacity, wherein the first throughput capacity is higher than the second throughput capacity. The method may further include selecting the first user plane function if the data throughput limit of the UE is above a predetermined threshold, selecting the second user plane function if the data throughput limit of the UE is below the predetermined threshold, and sending a session request to the selected first or second user plane function.
