Abstract: A first mobile network operator (MNO) periodically retrieves roaming network updates for reconfiguring one or more network subsystems of a network operated by the first MNO. A portion of the roaming network update is retrieved from an operator master database (OMD). The roaming network update includes roam data associated with a second MNO and configuration data for the one or more network subsystems. The roam data is retrieved via IR.21 information from a cloud server associated with the second MNO. The roam data specifies one or more telecommunications carriers associated with the second MNO. The one or more network subsystems for reconfiguration are identified based on the roaming network update. The one or more network subsystems are reconfigured using the roaming network update to enable one or more user devices associated with the second MNO for roaming on the network.

Abstract: A system ingests multiple roaming network updates for reconfiguring network subsystems of a network, and the network updates are received from multiple mobile network operators (MNOs). The system audits the network subsystems to determine a state of the network. For a particular network subsystem that includes multiple nodes located across different time zones, the system groups a set of updates across the multiple roaming network updates. The set of updates corresponds to the particular network subsystem. The set of updates is grouped for application to the multiple nodes across the different time zones. The system determines a maintenance window to update the state of the network based on the audit and applies, using an interactive shell client for the particular network subsystem, the set of updates to the particular network subsystem during the determined maintenance window. The applied updates permits user devices to roam on the network.

Abstract: A system periodically retrieves roaming network updates associated with at least one mobile network operator (MNO) using an application programming interface (API), and periodically ingests IR.21 information from cloud servers associated with the MNOs. The system retrieves configuration data for at least one network subsystem of a network. The system then performs an event-driven audit of the at least one network subsystem based on the ingested IR.21 information and queries the at least one network subsystem to determine discrepancies between a current network state and the IR.21 information. To rectify the discrepancies, the system determines a change to the network and maps the determined change with a network configuration table. According to the network configuration table, commands are automatically executed to apply the change and rectify the discrepancies. The network change enables user devices to roam on the network.
