Our innovative testing approach empowers comprehensive mobility management testing for mobile voice and data services, encompassing Voice over LTE (VoLTE), Voice over New Radio (VoNR), and OTT voice services. We ensure the accurate functionality of intricate radio interworking, covering a wide spectrum of mobility scenarios, including inter-system handover, intra-system handover, SRVCC, 5G dual connectivity verification, and more. Our RAN Verification Suite, based on SEGRON’s attenuator control and shielded boxes, supports these scenarios. Additionally, we offer in-depth analysis of related radio interfaces using Layer3 radio analysis.
