A remote querying system and a service provider repository system functionally cooperate to efficiently store configuration information of one or more subscriber devices within the service provider repository system. The remote querying system receives the configuration information of the one or more subscriber devices from a service provider system. Thereafter, the remote querying system determines differences between this received configuration information and configuration information that is previously stored in the service provider repository system. Next, the remote querying system communicates these differences to the service provider repository system to allow the service provider repository system to update the previously stored configuration information.
