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.

An intelligent gateway device provided at a premise (home or business) for providing and managing application services associated with use and support of a plurality of digital endpoint devices associated with the premises. The device includes a communications and processing infrastructure integrated with a peer and presence messaging based communications protocol for enabling communications between the device and an external support network and between the device and connected digital endpoint devices. A services framework at the gateway device implements the communications and processing infrastructure for enabling service management, service configuration, and authentication of user of services at the intelligent gateway. The framework provides a storage and execution environment for supporting and executing received service logic modules relating to use, management, and support of the digital endpoint devices. Thus, the gateway device provides a network-based services point of presence for a plurality of digital endpoint devices at the premises.

A system for preserving charging event messages in a mobile telecommunications network when a charging server is unavailable includes a message broker comprising persistent storage. The system also includes a network element that generates a charging event message, attempts to send the charging event message to a charging server, and writes the charging event message to the message broker in response to determining that the attempt to send the charging event message to the charging server has failed. The system also includes a replay agent that subscribes to the message broker for notifications associated with the charging server, receives a notification from the message broker about the charging event message, reads the charging event message from the message broker, and causes the charging event message to be sent to the charging server when the charging server is available.

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

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.

Apparatus comprising a plurality of servers and at least one router that are configured to receive from a communications network data records that the network generates, which are associated with IMSIs and comprise metadata characterizing communications that the network propagates, associate IMSIs with the data records, and store data records associated with a same IMSI in a memory correlated with their shared associated IMSI.

A method for cellular network outage detection including monitoring error rates associated with a network node of a cellular network for a first predetermined time period. The method includes determining a first baseline error rate for the network node based on the plurality of first error rates for the first predetermined time period, and determining a first threshold error rate for the network node based on the first baseline error rate for the network node. The method includes monitoring a plurality of second error rates associated with the network node for a time period subsequent the first predetermined time period, and detecting an excessive error rate of the plurality of second error rates associated with the network node, where the excessive error rate exceeding the first threshold error rate. The method includes, in response to detecting the excessive error rate, automatically executing a predetermined override rule.

Systems and methods for dynamically collecting information regarding network events in a 5G network are disclosed. The method includes locally storing event data initially and implementing post-event collection of the locally stored data when one or more collecting nodes become available.

Systems, methods, and devices can be utilized for policy control function (PCF) fallback during the set up of a session utilizing a 5th Generation (5G) core network. An example method includes receiving, from a session management function (SMF), a request for a policy corresponding to a session. The request includes a first policy identifier corresponding to a first policy control function (PCF). The example method further includes determining that the first PCF is unavailable, generating a modified request by replacing the first policy identifier with a second policy identifier in the request. The second policy identifier corresponds to a second PCF. The example method also includes transmitting, to the second PCF, the modified second request.
