A data transmission method, apparatus and related equipment, the data transmission method comprising: a first UE adding a first RBID and/or terminal identification information of the first UE to data to be sent, wherein the first RBID corresponds to The first RB is located between the first UE and the network side device, the first RBID is allocated by the network side device to the first UE, the terminal identification information is the layer 2 identifier of the first UE, and the layer 2 identifier is used to indicate the access network identification For the first UE, the terminal identification information includes C-RNTI, IP address, TMSI or IMSI; the first UE forwards the data after adding the first RBID and/or terminal identification information to the network side device through the second UE. By implementing the embodiment of the present invention, the network side device can identify the data type of the data according to the first RBID, and identify the source sender of the data according to the terminal identification information. |
