1. A method for managing voice/video over new radio (VoNR) calls, the method comprising:
detecting, by a user equipment (UE), a signal deterioration during a VoNR call based on at least one of absolute signal parameters and derived parameters;
sending, by the UE, a zero channel quality indicator (CQI) report and a measurement report to a base station on detecting the signal deterioration, wherein the measurement report comprises at least one of at least one neighbour new radio (NR) cell information, and at least one neighbour long-term evolution (LTE) cell information;
receiving, by the UE, a handover trigger for the VoNR call from the base station, based on the zero CQI report and the measurement report; and
continuing, by the UE, at least one of the VoNR call over a neighbour NR cell and the VoNR call as a voice over long-term evolution (VoLTE) call over a neighbour LTE cell, based on the handover trigger for the VoNR call.
