FIELD: radio engineering, communication.SUBSTANCE: invention relates to communication systems. A GPRS service support node splits a TCP retransmission packet into the data frames and adds retransmission identifiers to the data frames. In this way, after the base station subsystem receives a data frame, it can determine whether the data frame is the data frame obtained by splitting the TCP retransmission packet according to whether the data frame carries the retransmission identifier. If the data frame is the data frame obtained by splitting the TCP retransmission packet, the data frame is transmitted to a terminal as a priority, thus the transmission efficiency of the TCP retransmission packet is increased, which is the technical result.EFFECT: method and system for transmitting data frames and a base station subsystem are provided.12 cl, 7 dwg, 4 tbl |
