Why did China Telecom acquire the initial segment of Unicom 133?

This is the result of the country's overall consideration:

If mobile makes the most money, give it the most expensive TD-CDMA.

China Unicom's C network and G network fought hard, so we gave the C network to China Telecom, and China Unicom was liberated.

Telecom got the C network, which also solved the short board problem without mobile communication.
