US 11,153,765 B1 · Capacity planning of telecommunications network by detecting anomalies in site behavior

Abstract

Systems and methods to detect abnormal behavior of cell sites and/or customers are disclosed. By detecting cell site and/or customer behavior anomalies, the system enhances capacity planning by helping understand congestion, more efficiently planning event sites, suggesting installation of temporary solutions, identifying when true traffic needs are increased, and detecting abnormal customer behavior and/or demand. The system accesses historical data for a set of KPIs (e.g., 3 months of hourly data that captures traffic, users, Physical Resource Block (PRB), and throughput). The system computes, for periodic time intervals (e.g., for each hour and each day), upper and lower limits for each site and for each KPI. Using this information, the system detects anomalies for current KPI measurements. The system sends alerts when anomalies are detected for a threshold period of time (e.g., when the KPI measurement falls outside of the computed upper and/or lower bounds continuously for 2-3 hours).
