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.

Charging function fallback

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.
