Embodiment Construction

[0011] The embodiment of the present application provides an optimal calibration method for mobile terminals to solve the technical problem of reducing the quality of mobile terminal products in the prior art in order to shorten the calibration time of the receiver; when the mobile terminal meets the optimal calibration conditions, the previous The standard RSSI statistical value determined in the production cycle is used as the RSSI value for optimal calibration in this production cycle, which shortens the receiver calibration time, and the calibration is dynamically adjusted according to the production process, which also ensures the product quality of the mobile terminal while shortening the receiver calibration time. .

[0012] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0013] With the improvement of hardware c...

Abstract

The optimal calibration method for mobile terminals proposed by the present invention determines the monitoring object of the mobile terminal based on the RSSI monitoring list of the production model; obtains the production test data of the monitoring object; and judges whether the mobile terminal in the current production cycle is based on the production test data. Satisfy the optimal calibration condition; if satisfied, use the standard RSSI statistical value determined in the previous production cycle as the optimal calibration value of the mobile terminal in this production cycle, and write it into the mobile terminal with a set ratio in this production cycle to perform receiver optimal calibration; The standard RSSI statistic value determined in the previous production cycle is obtained by performing calibration according to the first calibration criterion by mobile terminals with a predetermined ratio. The standard RSSI statistical value determined in the previous production cycle is directly written into the mobile terminal with a set ratio in the current production cycle to perform optimal calibration. The calibration of the mobile terminal is dynamically adjusted based on the production process, and it is guaranteed when the calibration time is shortened. the quality of the product.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an optimal calibration method for mobile terminals. Background technique [0002] There are discrete types of radio frequency devices. Therefore, mobile terminals must be calibrated during the production process to meet the requirements of design indicators. [0003] The calibration of the mobile terminal during the production process includes crystal oscillator calibration, receiver calibration and emitter calibration. Among them, the receiver calibration is to set the mobile terminal to N calibration frequency points according to the communication system and radio frequency band, and set M-level base station levels respectively according to the design characteristics of the receiver channel, and read the levels for N*M base stations. RSSI (ReceivedSignal Strength Indication, received signal strength indication) value of the mobile terminal, and write the read RSSI val...
