Problems solved by technology

Therefore, the base station acquires the IMSI stored in the SIM of the mobile terminal, and performs authentication by checking the calculation result using the key information stored in the SIM. Therefore, the test device also needs to perform reconnection using the authentication process based on the above procedure. (Call connection), it is difficult to test the mobile terminal installed with the actual SIM whose memory content is unclear

Embodiment Construction

[0072] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0073] figure 1 It is a block diagram of an embodiment of the mobile terminal test apparatus 20 to which the present invention is applied.

[0074] The mobile terminal testing device 20 is a device that communicates with a mobile terminal by WCDMA or TD-SCDMA, and includes a test control unit 21 , a modulation unit 22 , a frequency conversion unit 23 and a demodulation unit 24 .

[0075] The test control unit 21 outputs a message Md notifying the mobile terminal 1 of the test object and a test data signal according to a predetermined order, and analyzes the data signal transmitted from the mobile terminal 1 to test and evaluate the mobile terminal 1 .

[0076] The modulation unit 22 performs modulation processing corresponding to the modulation method of the mobile terminal 1 on the output signal of the test control unit 21 , and outputs the signal to the frequency co...

Abstract

At the beginning of the operation of a mobile terminal 1 to be tested, link establishment means 211 performs a process of establishing a link to the mobile terminal 1. When the link is established, test mode change means 213 transmits 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 terminal 1 to be tested, thereby changing the mobile terminal 1 to be tested to a test mode, and performs a transmission and reception test.

Description

technical field [0001] The present invention relates to a technique for efficiently testing a mobile terminal such as a mobile phone, a smart phone, etc., which wirelessly communicates with a base station. Background technique [0002] In the communication system of the mobile terminal, the mobile terminal in the service area of ​​the base station receives the radio waves of the base station when the power is turned on or when the reset operation is performed, and sends a request to the base station to realize communication, so as to be able to communicate with the base station. state (link established state), next, the base station is notified of the unique information of the mobile terminal to perform authentication / location registration processing for registering the presence area of ​​the mobile terminal in the network to which the base station belongs, and then transitions to the idle state by the link opening process, and then, When it becomes necessary to perform comm...
