Abstract

The invention relates to a global mobile communication system technology and discloses a microphone calibration information acquiring method and a microphone. In the invention, a mark used for marking whether the microphone is calibrated or not is arranged in a coded program in the microphone, the value of the mark is set into a calibrated value after the microphone is calibrated, and the information whether the microphone is calibrated or not is acquired by querying the value of the mark. A tester can acquire the information whether the microphone is calibrated or not conveniently and simply by querying the mark, therefore, the test operation carried out on the microphone which is not calibrated or loses calibration data is effectively avoided, and the invalid test is avoided to the largest extent.

Description

technical field [0001] The invention relates to the global mobile communication system technology, in particular to the mobile phone calibration technology in the global mobile communication system technology. Background technique [0002] Global System for Mobile communication (Global System for Mobile communication, referred to as "GSM"), commonly known as "GSM", is a mobile communication technology standard that originated in Europe and is the second generation of mobile communication technology. Its development purpose is to allow all parts of the world to share Using a mobile phone network standard allows users to travel around the world with a single mobile phone. my country introduced and adopted this technical standard in the early 1990s. Before that, it has been using cellular analog mobile technology, that is, the first generation of GSM technology (my country closed the analog mobile network on December 31, 2001). At present, China Mobile and China Unicom each ha...
