Patent number: 11284215Abstract: Implementations described and claimed herein provide systems and methods for correlating one or more service areas of a network with one or more geolocation coordinates to determine available services for customers to the network. A service polygon may be generated that define an area in which a particular service offered by a communications network is available. The boundaries of the service polygons may be adjusted based on information corresponding to physical features of the initial area. The service polygons may aid a communications network in providing a list of available services to potential customers or devices connected to the network by determining one or more geolocation coordinate values of a potential connection site and comparing the values to the service polygons. A network management system may determine the available services, current or in the future, to offer such services to a customer to the network.Type: GrantFiled: February 19, 2020Date of Patent: March 22, 2022Assignee: Level 3 Communications, LLCInventors: Shawn Draper, Vamsi Kaza, Jerry Matthews, William Gray
