A method for transmitting a transcoder & rate adaptation unit (TRAU) frame over a packet network according to one embodiment of the present invention includes: receiving a packet TRAU (P_TRAU) frame sent from an opposite device; parsing the P_TRAU frame to obtain control information required for packet network transmission; and processing data in the P_TRAU frame according to the control information. A system and device for transmitting a TRAU frame over a packet network are also provided. With the P_TRAU frame that carries the control information required for packet network transmission, the Abis interface may use the packet mode instead of the time division multiplex (TDM) mode for transmission bearer and the delay, jitter, packet loss, and disorder in the packet mode are solved. |
