<P>PROBLEM TO BE SOLVED: To provide a radio base-station device evaluating system evaluating the operation of a radio base-station device when connecting with portable telephones with a plurality of lines at a lower cost. <P>SOLUTION: The radio base-station device evaluating system has an RNC simulator sending down-link signals containing data for evaluation to the radio base-station device, and comparing data contained in up-link signals with original data for every line and evaluating data contained in the up-link signals; and a UE simulator being connected to the radio base-station device with one line, transmitting the up-link signals to the radio base-station device when receiving the down-link signals, and comparing and evaluating received data and stored data. The radio base-station device evaluating system further has a signal generator multiplexing the up-link signals for residual lines, and transmitting the multiplexed up-link signals to the radio base-station device; and a signal receiver connected to the radio base-station device with the residual lines, demodulating the down-link signals for the residual lines to base-band signals, and conserving the demodulated down-link signals. The radio base-station device evaluating system further has a received-signal decoder converting the base-band signals into data by decoding for every line and comparing and evaluating converted data and stored data. <P>COPYRIGHT: (C)2008,JPO&INPIT |
