5G voice call quality evaluation method and device, equipment and storage medium

The embodiment of the invention relates to the technical field of 5G voice communication, and discloses a 5G voice call quality evaluation method, device and equipment and a storage medium, and the method comprises the steps: triggering an EPS Fallback signaling process based on a switching mode when a PDU session establishment request initiated by UE is received in a 5G network; when an EPS Fallback signaling process based on a switching mode is executed, counting a first number of times that an AMF sends a first preset message to a PGW-C + SMF and a second number of times that an SGW sends a second preset message to the PGW-C + SMF; calculating the fallback success rate of the EPS Fallback according to the first number of times and the second number of times; and evaluating the quality of the current voice call according to the fallback success rate. The fallback success rate is obtained through calculation, and the fallback success rate is used as an index for evaluating the 5G voice communication quality.
