Claim 0:
1. An electronic device, comprising:
an indoor positioning tag, configured to transmit a wireless signal including an acceleration magnitude, an acceleration direction, and a duration of acceleration change;
wherein the indoor positioning tag comprises a gravity sensor; the indoor positioning tag determines whether to start to transmit the wireless signal according to the acceleration magnitude, the acceleration direction, and the duration of acceleration change detected by the gravity sensor, and adjusts a frequency of transmission interval of the wireless signal;
wherein the indoor positioning tag determines whether to perform a coordinate axis calibration for the gravity sensor according to the acceleration magnitude and the duration of acceleration change;
wherein when the acceleration direction remains the same, the acceleration magnitude is larger than a first threshold, and the duration of the acceleration magnitude that is larger than the first threshold is longer than a first period, the indoor positioning tag starts to transmit the wireless signal; and
when the indoor positioning tag remains in a stationary state in a second period, the indoor positioning tag stops transmitting the wireless signal.
