The calibration method includes: obtaining a current temperature of the crystal; searching a unique frequency-divide coefficient corresponding to the current temperature from a preset data base; if the coefficient is found in the data base, inputting the unique coefficient into a frequency divider; if the coefficient is not found in the data base, obtaining an actual sleep length of the mobile communication terminal, if the actual sleep length is not equal to a required sleep length, calculating a required frequency-divide coefficient and updating the data base with the required frequency-divide coefficient, and if the actual sleep length of the mobile communication terminal is equal to the required sleep length, updating the data base with a current frequency-divide coefficient. Accordingly, slow-clock calibration is realized with reduced crystal costs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Slow-clock calibration method and unit, clock circuit, and mobile communication terminal","description":"A slow-clock calibration method, a slow-clock calibration unit, a clock circuit and a mobile communication terminal are provided.
