The invention discloses a satellite signal searching method and device. The method comprises the following steps: searching a first satellite signal; suspending the searching of the first satellite signal when the first satellite signal searching is failed, and searching a second satellite signal; recovering the searching of the first satellite signal when the second satellite signal searching is failed, wherein the power consumption for searching the first satellite signal is greater than the power consumption for searching the second satellite. Therefore, the searching of the first satellite signal with large searching power consumption is suspended under the environment that the satellite signal is weak; the second satellite signal with small searching power consumption is searched so as to detect whether the satellite signal is recovered, when the second satellite signal is searched, the method regards that the satellite signal is recovered, and the searching of the first satellite is recovered, thereby lowering the average searching frequency of the first satellite signal with large searching power consumption on the whole; the system power consumption is lowered, the cruising capacity is improved, and the standby time of the terminal is prolonged.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a satellite signal search method and device. Background technique [0002] Satellite mobile communication terminals transmit signals through satellites distributed in space to realize satellite communication functions. Satellite signals are easily covered by objects such as large buildings or mountains. In this case, there is no satellite signal or the satellite signal is very weak, which makes the satellite communication function of the satellite mobile communication terminal unavailable. At this time, the satellite communication unit of the satellite mobile communication terminal will still continue to search for satellite signals and update its location in an attempt to restore the satellite communication function. [0003] However, the star search process consumes a lot of power, and the location update process needs to send data packets, which consumes more power, wh...
