DATA TRANSMISSION METHOD, SYSTEM AND RELATED DEVICE

摘要

Embodiments of the present invention disclose a data transmission method and system, and a related apparatus. The method in the embodiments of the present invention includes: when a network-side data transmission apparatus detects that a terminal is handed over from being served by a source base station to being served by a target base station, determining whether the source base station and the target base station have a wireless network transmission optimization WNTO technical capability; and completing transmission of uplink data or downlink data according to each determined WNTO technical capability of the source base station and the target base station, which effectively improves data transmission efficiency in a wireless network.
