Fault Diagnosis of 5G Voice Service Based on Multi-sources data.

EPS-Fallback is generally adopted for voice service in the coexistence period of 4/5G network Its process is very complex and prone to failure. How to guarantee users perception is an important challenge. Based on multi-resources data, this paper proposes a fault diagnosis method for EPS-Fallback. It can effectively improve the fault diagnosis ability and the efficiency of network operation and maintenance. Also, it can save labor costs.
