US 11,765,278 B2 · Replay agent for delivering charging event messages from a message broker in a mobile telecommunications network

Abstract

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.

Dependent claims

In a fifth generation (5G) telecommunications environment, a method for preserving charging event messages in a mobile telecommunications network based on a charging server being unavailable, the method being implemented by a replay agent, the method comprising:

assigning the replay agent to a plurality of charging servers;
subscribing to a message broker to receive, at the replay agent, notifications for messages that a network element failed to deliver to one or more of the plurality of charging servers;
receiving, based on subscribing to the message broker, a notification from the message broker about a charging event message that has been written to the message broker;
reading the charging event message from the message broker;
identifying the charging server from the plurality of charging servers where the charging event message should be sent;
determining a protocol that should be used to send the charging event message to the charging server;
and
causing the charging event message to be sent to the charging server using the determined protocol when the charging server becomes available.

5 more elements

In a fifth generation (5G) telecommunications environment, a system for preserving charging event messages in a mobile telecommunications network based on a charging server being unavailable, the system comprising:

one or more processors;
a message broker comprising persistent storage;
a network element that is executable by the one or more processors to generate a charging event message, attempt to send the charging event message to the charging server, and write 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;
and
a replay agent assigned to the charging server, the replay agent having instructions thereon being executable by the one or more processors to:
subscribe to the message broker to receive, at the replay agent, notifications for messages that the network element failed to deliver to the charging server;
receive, based on subscribing to the message broker, a notification from the message broker about the charging event message that has been written to the message broker;
read the charging event message from the message broker;
and
cause the charging event message to be sent to the charging server when the charging server becomes available.
