Problems solved by technology

This reduces the efficiency of testing
[0011] Also, no solution has been proposed to solve the problem that may occur while the MSUT is trying to register itself at the base station involved in the NV item before the value change of the NV item is started simultaneously for several MSUTs proceeding
[0012] In particular, related existing test systems do not address impedance mismatches that may arise when an inferior MSUT is connected to a divider

Embodiment Construction

[0032] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Where possible, the same reference numbers are used in the drawings to refer to the same or like parts.

[0033] figure 1 The structure of an apparatus for testing a mobile station in which GPS is equipped according to a preferred embodiment of the present invention is shown.

[0034] refer to figure 1 , in an idle mode test for testing the performance of a mobile station with a global positioning system, it is assumed that a traffic channel has not been established between the MSUT 15 and the base station testing device 11. Assume further that MSUT 15 is in idle mode.

[0035] When the MSUT 15 is started, the MSUT 15 attempts to register itself with the base station test device 11 involved in which the NV entry value is stored. At this point, the diagnostic monitoring device 13 does not intercept the attempt by changing...

Abstract

Disclosed are an apparatus and method for testing performance of a mobile station having a global positioning system (GPS) mounted therein. The method provides for virtually changing parameters requited for a registration at a base station so that the mobile station excludes the registration and directly enters a test state with an idle mode, and testing the performance of the mobile station in the idle mode test state. Accordingly, no re-boot is necessary to register with the base station upon completion of the test.

Description

technical field [0001] The present invention relates to mobile communication systems, and in particular, to an apparatus and method for testing the performance of a mobile station in which a Global Positioning System (GPS) is installed. Background technique [0002] Currently, development and application in the field of information communication involving technology using mobile stations has been greatly advanced. In particular, there has been growing interest in the field of mobile stations with positioning information acquisition systems using satellite communications, such as GPS. [0003] Qualcomm's "gpsOne" technology is used to track the location of Code Division Multiple Access (CDMA) mobile stations in which gpsOne functionality is incorporated. Tracking is accomplished through a hybrid technology that combines the functionality of GPS and a network based positioning terminal technology. Thus, GPS tracks the position of the GPS receiver on the ground by measuring t...
