Patent ID: 8498581

Claim:
A communication test device, comprising: a base station unit for performing wireless communication with a mobile communication terminal under test on the basis of a designated communication standard; accumulating means for accumulating trace data regarding a specific unit of data to be exchanged between said mobile communication terminal and said base station unit and throughput data regarding throughput for said specific unit of data in association with time information indicative of the time of sending and receiving said specific unit of data; extracting means for extracting said trace data and said throughput data from said accumulating means; a display unit on which said trace data extracted by said extracting means are displayed by trace display means, and a graph showing the variation with time of throughput based said throughput data extracted by said extracting means is displayed by throughput display means; and time obtaining means for obtaining a time corresponding to at least one point on said graph selected for a designated analysis within said graph, wherein said extracting means extracts, from said accumulating means, said trace data corresponding to said time information relating to said time obtained by said time obtaining means, and said trace display means displays said trace data corresponding to said time obtained by said time obtaining means on said display unit in a way that said trace data corresponding to said time obtained by said time obtaining means is distinguished from other trace data on said display unit, wherein said throughput display means displays a graph showing individually the variation with time of throughput based on said designated communication standard and the variation with time of throughput based on other communication standard in response to the variation of said wireless communication based on said designated communication standard to said wireless communication based on other communication standard.
