The invention discloses a network element and a method for uploading MR (Measure Report) messages by the network element. The method comprises the following steps of: receiving the MR messages and CDL (Call Detail Logs) messages which are reported by a terminal and a base station; independently forming an MR file from the received MR messages; when determining that an MR interface link between the network element and an MR server is normal, reporting the MR file to the MR server by adopting a mode of an FTP (File Transfer Protocol), so that the MR server generates a performance index file according to the MR messages in the MR file. According to the network element and the device disclosed by the invention, the processing capability of the network element which receives the reported MR messages is improved; the packet loss problem of the MR messages is ensured not to exist; the correctness of the performance index files obtained by a network optimization platform and a northbound webmaster is powerfully guaranteed; and the processing efficiency of the northbound webmaster on the performance index files is effectively promoted.
