  • Publication number: 20230292097
    Abstract: The described technology is generally directed towards an adapting radio access network coverage for location-based alerts. A group of cells and/or cell sectors can be selected for sending an alert, according to selection techniques described herein. The selection techniques can provide a target level of cellular coverage for a geographic area, while avoiding over-inclusion of cells and consequent dissemination of alerts to subscribers outside the geographic area. The target level of coverage can comprise a desired amount of service overlap, to achieve a corresponding level of confidence that subscribers within the geographic area will receive an alert. The selection techniques can furthermore close identified coverage gaps within the geographic area.
