Abstract: A system for changing roaming policy configuration on an authentication, authorization, accounting (AAA) system. The system comprises a processor, a non-transitory memory, and an AAA policy change application stored in the non-transitory memory. When executed by the processor, the AAA policy change application launches execution of a plurality of instances of the automation script, monitors a progress of the instances of the automation script, compares the progress of the instances of the automation script to a time remaining of a predefined maintenance time window, where the AAA policy change application is configured to halt an in-progress update of roaming policy configuration on the plurality of AAA nodes based on the comparison of the progress of the instances of the automation script being insufficient relative to the time remaining of the predefined maintenance time window, and copies roaming policy files updated by the automation script to AAA nodes.

Abstract: A middleware messaging system hosted on a telecommunications network computer system is configured to route messages between a message queue (MQ) messaging system of a customer information system (CIS) and a point-to-point messaging system of a service control point management system (SCPMS). The middleware messaging system includes configurable components comprising a plurality of service delivery platform (SDP) consumers and SDP producers, where a status of the configuration components is dynamically changed by at least one of a configuration file, table entries in a database, or a management web page, and where the middleware messaging system is configured to receive a failover message from the backup node indicating a second instance of the telecommunication application is hosted on the backup node; determine messages pending a response from the first instance of the telecommunication application; and transmit the messages to the second instance of the telecommunication application.
