Abstract

The disclosure relates to a network handover method, a computer device, and a storage medium. The method comprises: when a ping-pong handover is detected, recording the number of ping-pong handovers; when the number of ping-pong handovers reaches a pre-set number of times, acquiring an optimized reporting parameter; measuring the signal strength of the current camping cell and a neighbor cell to obtain measurement results; and based on the measurement results and the optimized reporting parameter, determining whether an A3 event is reported. By the method, when the number of ping-pong handovers of a terminal reaches the pre-set number of times, whether the A3 event is reported is determined according to the optimized reporting parameter and the measurement results.
