Abstract: The present invention relates to a data transmission method and apparatus. The data transmission method includes: acquiring associated count values of received protocol data units PDUs, determining N candidate count values, where the N candidate count values are in a one-to-one correspondence with the N data streams, and the candidate count value is a maximum value of associated count values of PDUs from each data stream and in the received PDUs, selecting a minimum value from the N candidate count values as a currently submissible count value; and when the associated count values of the received PDUs meet a submitting condition set according to the currently submissible count value, submitting PDUs of which associated count values meet the submitting condition to an upper-layer communication layer of the first data link layer.

Abstract: A method, device and system are used for transmitting a Multimedia Broadcast Multicast Service (MBMS). The method includes sending, by a first base station, a service identifier of a MBMS that needs to be received by a user equipment in a coverage area of the first base station to a gateway. The first base station receives a data packet of the MBMS and a synchronization control packet on a first multicast channel which are sent by the gateway. The first multicast channel is a multicast channel where the MBMS is located.
