  • Patent number: 9980243
    Abstract: Systems and techniques for synchronization between in-coverage and out-of coverage user devices. A base station configures in-coverage and out-of coverage synchronization signals and configures user devices to recognize synchronization signals as in-coverage or out-of-coverage. An in-coverage device furnishes an in-coverage synchronization signal upon detection of an out-of coverage signal, and may continue to furnish the signal upon continued detection of an out-of-coverage signal that is not synchronized to the network. An out-of-coverage device may receive and synchronize to an in-coverage signal if available, or an out-of-coverage signal if available, or may generate and transmit its own out-of-coverage signal if no in-coverage or out-of-coverage signal is available.

  • Publication number: 20170324740
    Abstract: Described herein is a framework for providing and securing data access by external users. In accordance with one aspect of the framework, an external schema is generated to pair with an existing company schema in a database. The company schema may own data stored in the database. One or more access-control views that expose one or more subsets of the data may further be generated. The external schema may be granted access to the one or more access-control views. Synonyms may be created to rename access-control views, so that the synonyms share common names with corresponding database objects accessible via the company schema. External users may then access the data visible to them via the synonyms that are used to alias the access-control views.
