AI Technical Summary

⚠Technical Problem

In mobile areas such as railway transportation, existing technologies suffer from data transmission failures or delays due to network switching at different levels. In particular, when the coverage quality of high-level networks is poor, the automatic switching strategy on the network side leads to unstable communication for IoT terminals.

⚗Method used

By actively measuring the signal quality of each network level along the driving route, dividing the driving section, and selecting the network level with the highest signal quality in each section, the network switching of the vehicle-mounted mobile terminal is realized to keep the communication terminal in the optimal network level at all times.

🎯Benefits of technology

It improves the quality of communication services, reduces data transmission failures and delays, and ensures that in-vehicle mobile terminals always operate under optimal network coverage.
