Abstract: |
Ultra-dense network(UDN)is one of key technologies for 5G network architecture whose delay and invalid handover caused by handover have become huge challenges for network deployment.In order to reduce handover delay and unnecessary handover,an improved machine learning algorithm based on the user's mobility data is proposed to perform higher-precision prediction.The simulation results show that by using the handover strategy combined with the improved machine learning algorithm,unnecessary handover can be reduced 40.2%,average latency about 28.6%. |
