Network Outage Detection

Abstract

Systems, apparatuses, and methods are described for detecting network service failure and potential source of failure in a communication network employing registration requests. A current quantity of registration requests may be compared against an expected quantity of registration requests, and a network alert may be sent based on the comparison.
