Patent ID: 8036652

Claim:
A radio access point testing apparatus, comprising a plurality of radio processing units, a testing access terminal and a control unit, the testing access terminal including: a terminal function portion which has a transmission function and a reception function of a communication terminal in a radio communication system, and in which an initial transmission power from the terminal function portion in case of performing a calling connection is determined in accordance with reception power; and a test function control portion which causes said terminal function portion to perform a calling connection through said radio processing unit, so as to test normalcy and abnormalcy of a radio access point, each radio processing unit including a transmitter for transmitting signals to said terminal function portion and the communication terminal, and a receiver for receiving signals from said terminal function portion and the communication terminal, wherein said radio access point testing apparatus further comprises: a reception power measurement part for measuring reception power in said receiver including power of a radio signal from the communication terminal and/or interference waves in said radio processing unit; and a variable attenuator in said terminal function portion, wherein said reception power measurement part is configured to connect with said control unit, to monitor reception power value and to report it to said control unit; upon receiving an instruction of a performance of the normalcy test from an upper apparatus, said control unit calculates a difference between the reception power value reported from said reception power measurement part and predetermined thermal noise power in the nonexistence of the external noise, and reports the difference to said test function control portion; said test function control portion controls the initial transmission power of said terminal function portion by adjusting an attenuation magnitude of said variable attenuator based on reported difference; said terminal function portion performs the calling connection with the predetermined device by the controlled initial transmission power; and said control unit performs the test of the radio access point.
