The invention relates to the field of WCDMA (Wideband Code Division Multiple Access) wireless communication and discloses a method for testing parameters of a WCDMA network. The method comprises a testing server and a client; and four parameters of state conversion time delay, state conversion timer, an RLC buffering threshold and RLC buffering consumption rate are deduced through comparing round-trip delays of the server and the client during transmitting and receiving data packets with different sizes at different time intervals. The method for testing parameters of the WCDMA network, provided by the invention, has the advantages of simplicity, rapidness, high accuracy and higher application value.
