Each user provided geographic polygon layer within this data set is represented by one or more polygons, with each polygon containing routing criteria, routing rules, priority, and expiration parameters. This geographic data set may also have a base geographic polygon layer of one or more polygons that define the “normal” or “default” routing conditions. Utilizing a user provided geographic data set the PRF interrogates an emergency caller's location against the polygon(s) and applies the routing rules of the highest level geographic polygon layer polygon that has a true routing condition."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Geographic policy routing function","description":"A policy routing function (“PRF”) allows requests for emergency services (e.g., 9-1-1 calls, text messages to 9-1-1, etc.) dynamically routed to an emergency responder based on rules and/or user defin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641679","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
