Abstract

A data transmission method, adapted for a base station device, includes: determining whether an end device is in at least one of an unstable state, a pre-operation state of data transmission, and a measurement state according to report data of the end device; if so, entering a first mode to provide a first signal service range; and if not, enter a second mode to provide a second signal service range greater than the first signal service range.
