First Claim
1. A data transmission method, comprising:
- detecting, by a data transmission apparatus, that a terminal is handed over from being served by a source base station to being served by a target base station;
determining, by the data transmission apparatus according to a fingerprint database, whether the source base station and the target base station have a wireless network transmission optimization (WNTO) technical capability; and
completing data transmission according to each determined WNTO technical capability of the source base station and the target base station,whereinthe determining, by the data transmission apparatus, whether the source base station and the target base station have the wireless network transmission optimization (WNTO) technical capability comprises;
determining, by the data transmission apparatus, that both the source base station and the target base station have the WNTO technical capability, andthe completing the data transmission according to each determined WNTO technical capability of the source base station and the target base station comprises;
sending, by the data transmission apparatus, a synchronization command message to the source base station, so that the source base station synchronizes the fingerprint database to the target base station, wherein the synchronization command message carries an identifier of the terminal and an identifier of the target base station; and
when the source base station successfully synchronizes the fingerprint database to the target base station,compressing, by the data transmission apparatus, downlink data by using a WNTO technology, andsending, to the target base station, compressed downlink data obtained after the downlink data is compressed by using the WNTO technology, so that the target base station decompresses the compressed downlink data according to the fingerprint database by using the WNTO technology.
