Embodiment 1
[0046] Embodiment 1: The mobile terminal of user A is embedded with a SIM card of China Mobile and a SIM card of China Unicom. In some large gatherings or places with high population flow (such as bus stations, railway stations, hospitals, etc.), when the number of China Mobile SIM card users is large, the current available network resources of all China Mobile SIM cards will be reduced. Internet speed will also be affected. Through the optimized use method of the 4G network provided by the embodiment of the present invention, when the SIM card of China Mobile and the SIM card of China Unicom both reside in the 4G network and the flow margin of the two is equivalent, it can be known through the channel quality indication information The callable network resources of China Unicom’s SIM card are better than that of China Mobile’s SIM card, so the mobile terminal will automatically set China Unicom’s SIM card as the main card, thereby optimizing the usage of 4G network data traff...
