At step S220, mobile terminal 120, after receiving distance measuring instruction, is opened bluetooth automatically, and by message informing, informs mobile terminal 110 at step S230.
At step S240, mobile terminal 110 is opened bluetooth.
At step S250, mobile terminal 110 (for example, RSSI) is determined the distance between mobile terminal 120 and mobile terminal 110 according to the intensity of the Bluetooth signal of the mobile terminal 120 receiving.This can utilize existing bluetooth ranging technology to realize.This distance can be shown to the user of mobile terminal 110 in real time.
At step S260, mobile terminal 110 determines that this distance is whether in a certain preset range.This preset range can be " 100 meters～50 meters ", " 50～25 meters ", " 25 meters～10 meters " etc.This depends on the bluetooth standard of concrete employing.
At step S270, when mobile terminal 110 monitor and mobile terminal 120 between distance in this preset range time, mobile terminal 110 sends sounding instructions to mobile terminal 120, in order to indicating mobile terminal 120, sends specific sound.For example, this sounding instruction can send by network 130 or other suitable forms, and for example the form with note or networking sends.
At step S280, mobile terminal 120, after receiving sounding instruction, continues to send specific sound immediately.Even if it should be noted that mobile terminal 120, originally in vibration and mute state, also will sound after receiving this sounding instruction.
This preset range can comprise one or more subranges, the sound that each subrange is corresponding different.For example, when dwindling a magnitude, distance can change sound, such as " 100 meters～50 meters " a kind of sound, " 50～25 meters " a kind of sound.
Like this, the specific sound that user can send according to mobile terminal 120 and the real-time distance between mobile terminal 110 and mobile terminal 120 find mobile terminal 120 more quickly.
