At the beginning of the operation of a mobile terminalto be tested, link establishment meansperforms a process of establishing a link to the mobile terminal. When the link is established, test mode change meanstransmits a message 'downlink Direct Transfer (Activate RB Test Mode)' for setting test mode connection from a base station, returns a response message to a message transmitted from the mobile terminalto be tested, thereby changing the mobile terminalto be tested to a test mode, and performs a transmission and reception test.

Mobile terminal test device and method

At the beginning of the operation of a mobile terminalto be tested, link establishment meansperforms a process of establishing a link to the mobile terminaland location registration meansperforms a location registration process. Then, test mode change meanstransmits a message 'downlink Direct Transfer (Activate RB Test Mode)' for setting test mode connection from a base station, returns a response message to a message transmitted from the mobile terminalto be tested, thereby changing the mobile terminalto be tested to a test mode, and performs a transmission and reception test.

A mobile terminal testing device includes a reproduction unit that reproduces a BB signal to output at least one reproduced BB signal, an adder that adds a BB signal that are frequency-shifted and a reproduced BB signal to output an added BB signal, an up-converter that generates a multicarrier test signal by making a frequency conversion of the added BB signal of an I phase and Q phase and outputs the multicarrier test signal to UE, and an analyzer that analyzes a response signal output by the UE in response to the multicarrier test signal and the analyzer includes a throughput calculation unit that calculates throughput for the multicarrier test signal and an RSRP acquisition unit that acquires RSRP.

Device to test mobile terminal and testing method thereof

To enable addition or changes of functions with changes of communication standards in a mobile communication terminal test system. A mobile communication terminal test system includes a transceiver which has a control unit configured to append input information to acquired waveform data, a signal analysis unit which executes an analysis program, and a signal analyzer which is provided separately from the transceiver. The analysis program has a processing program which is provided for each type of arithmetic processing on the waveform data, a control program which is provided for each communication system, selects one or more processing programs for each test item, and executes the processing programs, and a switching program which specifies a communication system and a test item on the basis of the input information, and selects and executes a control program.

Mobile communication terminal test system, analysis method, and analysis program

A signal analyzer for facilitating observation of a relative value, i.e., the quantity of variation in power between slots, at the time of analyzing the power of a signal which is to be measured and subjected to power control in units of slot. An analyzing section detects the power value of every slot of a signal which is to be measured and received at a receiving section, and calculates the relative value of the power value between each slot and a slot separated therefrom by a predetermined number. A display control section displays the relative values thus calculated as a graph at a display section by arranging them continuously in time series.
