Patent number: 10531372Abstract: Disclosed are various embodiments for managing location-based service zones being monitored by a client device. The location-based service zones within a geographic region can be organized in location-based service zone clusters. In response to receiving an active zone from a computing device, a client device can begin monitoring the geographic parameters for the top-level location-based service zone clusters. When the client device detects an entry into a particular location-based service zone cluster, the client device stops monitoring the top-level location-based service zone clusters and begins monitoring the location-based service zones that are within the particular location-based service zone cluster.Type: GrantFiled: August 7, 2017Date of Patent: January 7, 2020Assignee: Amazon Technologies, Inc.Inventors: Sergey Parshin, Ronen Barenboim, Michael Bowerman, Jon Robert Ducrou, Ryan Hapgood, Qiwei Liu, Michael Schollmeyer, James Michael Sutula
