Abstract: Systems, methods, and devices that relate to generation of responses to query sets are disclosed. In one example aspect, the system uses multiple models to retrieve data relevant to queries and appropriate for the requesting user and to output the data in a certain style. In particular, the system uses a first model to determine a type of user submitting a query, a second model to retrieve data relevant to the query, subject to constraints based on the type of user, and a third model to formulate a response to the query, based on the retrieved data, using a consistent style. In some implementations, another model enables certain users to validate the outputs from one or more of the first, second, and third models. The system can output a compilation of the responses to the queries in a particular manner, style, or presentation that is consistent across all outputs.

Abstract: A method of managing voice calls in LTE/4G telephony for a mobile handset roaming outside of its home network in a network where voice calls use 3G technology, using a Global Location Register (GLR) which is designed to manage registrations without informing the home network. The method involves registering the mobile handset in 4G at the roaming network, obtaining and prestoring 3G information for the mobile handset from the home network while the mobile handset is registered in 4G, obtaining a voice call request for the mobile handset; and reregistering the mobile handset in 3G at the roaming network to use circuit switch fallback for the voice call, the reregistering comprising using the prestored 3G information so that the home network does not have to be contacted.
