International Classification:

H04W 4/24
H04W 28/04
H04W 8/20
H04W 8/02

Abstract:

Systems, methods, and devices can be utilized to provide charging function (CHF) fallback in a 5Generation 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.

International Classification:

H04W 76/11
H04W 64/00
H04W 48/20

Abstract:

Selecting local gateways for VoWiFi and/or ViWiFi calls (voice traffic sessions) for a user equipment (UE) includes: receiving, by an evolved packet data gateway (ePDG), a request to initiate the voice traffic session from a WiFi router outside a cellular network that is communicatively coupled with the UE; based on at least an internet protocol (IP) address of the WiFi router or the UE, determining a geographical location of the UE; based on at least the geographical location of the UE, determining a tracking area code; based on at least the tracking area code, determining an IP address of a network gateway proximate to the UE, wherein the network gateway comprises a user plane function (UPF) and a session management function (SMF) or a packet data gateway (PGW) user plane function (PGW-U) and a PGW control plane function (PGW-C); and establishing the voice traffic session using the network gateway.

International Classification:

H04W 36/32
H04W 36/24
H04W 36/00

Abstract:

A method for selecting a gateway node to support handover when a user equipment (UE) attaches to a 4G long-term evolution (LTE) network may include receiving a prediction from a machine learning engine predicting whether the UE is more likely to handover between the 4G LTE network and a 3G network or between the 4G LTE network and a 5G network based on handover data in the UE's location area. The method may further include selecting a first gateway node if the prediction indicates that the UE is more likely to handover between the 4G LTE network and the 3G network, and selecting a second gateway node if the prediction indicates that the UE is more likely to handover between the 4G LTE network and a 5G network. The first gateway node may support 4G and 3G sessions, and the second gateway node may support 4G and 5G sessions.

International Classification:

H04W 48/04
H04W 64/00
H04W 76/11
H04W 8/24

Abstract:

A telecommunication network associated with a wireless telecommunication provider can be configured to select user-plane functions (UPFs) for a user equipment (UE) in a network, and the handover of subscriber sessions. According to some configurations, a nearest UPF to the UE can be picked to service the UE. Choosing the nearest UPF may reduce latency to the UE when sending and receiving packets through a cellular network, such as a G network. Subscriber sessions can be handed over across multiple UPFs based on mobility of the UE. Subscriber sessions may be anchored on UPFs located either on edge locations or centralized data centers. Because of mobility of subscribers from a first location (e.g., x) to a second location (e.g., y), a subscriber's session can be moved from one user plane node to another user plane node seamlessly.

International Classification:

H04W 24/04
H04L 29/08

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.
