DATA TRANSMISSION METHOD, SYSTEM AND RELATED DEVICE

摘要

Disclosed in an embodiment of the present invention are a data transmission method, system and related device, the method comprising: when the data transmission device of a network side detects that a terminal is provided with service by a target base station instead of a source base station, determining whether the source base station and the target base station have wireless network transmission optimization (WNTO) technical capacity; and according to the determined WNTO technical capacity of the source base station and the target base station, transmitting uplink data or downlink data, thus effectively improving data transmission efficiency in a wireless network.
