MIFI clock self-calibration method

Abstract

The invention provides an MIFI clock self-calibration method. The method comprises the steps that first, terminal equipment with an MIFI is provided, and the terminal equipment is made to be in a starting-up state; second, whether a wireless communication network is in communication connection or not is judged, and the wireless communication network comprises a 3G or 4G wireless network; third, clock calibration is conducted on the terminal equipment according to the judgment result in the second step. The third step comprises the following steps that first, a network calibration time signal is received through the wireless communication network, and a clock of the terminal equipment is adjusted; second, a radio calibration time signal is received through a radio shortwave network, and the clock of the terminal equipment is adjusted. The MIFI clock self-calibration method provides a novel technical scheme for self-calibration of the MIFI clock, and can guarantee all-weather MIFI clock calibration whether the MIFI clock is connected to the 3G network or the 4G network or not.

Description

technical field [0001] The invention relates to a MIFI clock checking method. Background technique [0002] MIFI mainly connects to the World Wide Web through a 3G or 4G wireless communication network, and obtains data from the World Wide Web. At the same time, the MIFI will provide Wi-Fi services to intelligent mobile terminals within a certain range according to the wireless Internet access method. The MIFI can establish a wireless communication network within the certain range, and the wireless communication network does not require a connection to a 3G or 4G network as a prerequisite. [0003] At present, the clock of MIFI mainly obtains calibration time information from a time server on the World Wide Web, so as to realize clock verification. [0004] However, there is an insurmountable defect in the above-mentioned method of obtaining calibration time information to realize clock verification, that is, when the MIFI is in a space without a 3G or 4G network and cannot...
