The present disclosure relates to a system (100) and a method for switching user equipment(s) (UEs) between communication networks (4G, 5G, and 6G). The method includes detecting an outage (service failure or interruption in service) in a network based on a reference signal received power (RSRP), a reference signal received quality (RSRQ), and a signal-to-interference-plus-noise ratio (SINR) and switching the UE from a first network to a second network. On detecting the outage, a mobility management entity (MME) queries a home subscriber server (HSS) for the UE usage type.
