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

The disclosed embodiments include a method for offline charging performed by an anchoring node of a telecommunications network. The anchoring node can send a request to an online charging system (OCS), where the request is for online metering of a call by a subscriber of the telecommunications network. The anchoring node may obtain an indication of an exception to the online metering of the call. In response, the anchoring node can perform a default call handling (DCH) procedure to allow the call on the telecommunications network despite an inability to perform the online metering. The anchoring node also generates a modified charging detail record (CDR) that includes an indication of the exception. The anchoring node can then send a message, which includes at least an indication of the modified CDR, to enable a mediation server to perform offline charging for the call.

Offline charging of communications services

This disclosure describes techniques for monitoring network node traffic and dynamically re-directing network node traffic from an active repository that has a non-operational data cluster, to a standby repository with an operational alternate data cluster. Particularly, a 'Data Redundancy Allocation' (DRA) system is described that can monitor the operational integrity of an active repository and dynamically co-ordinate and re-direct network node traffic to a standby, redundant data repository in response to detecting that the active repository is no longer operational. In doing so, the data redundancy allocation system may ensure a continuous communication stream of data traffic from network nodes to data repositories (i.e., active repository or a designated standby repository) in spite of a data repository inadvertently becoming non-operational, or intentionally brought offline for a planned upgrade.
