<p>Disclosed is a method for detecting service frame loss of an uplink Enhanced-Dedicated Channel (E-DCH). The method comprises: in a Node B (NodeB), independently maintaining a frame sequence number by each transmission bearer, then sending a frame sequence number carried in a data frame to a serving radio network controller (SRNC); and the SRNC judging whether or not the transmission bearer loses a frame according to the frame sequence number in the received data frame. Also disclosed is a system for detecting service frame loss of an uplink E-DCH. The method and system enable the detection of E-DCH data transmission congestion and the indication of the functional process using a frame sequence number and, particularly, in a multiplexing transmission bearer mode, enable the mode of frame-loss detection to be more rational, reducing load on the system.</p> |
