Patent number: 10917801Abstract: Various embodiments disclosed herein provide for a tower outage impact predictor that can determine the service impact on an end user during a cellular tower outage. Radio signal profiling divides an area into grids, and then constructs a radio signal profile for each grid based on user equipment (UE) measurement data for each grid. The number of UEs in each grid is then determined, and then the number of UEs that lose service for a simulated cellular tower outage is determined. Based on the impact analysis, a more resilient backhaul network can be implemented by determining backhaul rehoming changes that optimally home cellular towers to various backhaul network devices.Type: GrantFiled: April 27, 2018Date of Patent: February 9, 2021Assignees: AT&T INTELLECTUAL PROPERTY I, L.P., GEORGIA TECH RESEARCH CORPORATIONInventors: He Yan, Zihui Ge, Dongmei Wang, Sen Yang, Jun Xu
