Abstract

The invention discloses a signal sending method and a mobile terminal, which relate to the field of communication. In the invention, after the mobile terminal judges that the sending condition of a wireless beacon is satisfied, if network signals can not be searched in the preset duration, or indications of users to send the wireless beacon is received through a man-computer interface, the timing sending of the wireless beacon is started, and the wireless beacon is a rescue signal at a specific frequency. Through the starting of the timing sending of the wireless beacon in the emergency state, the mobile terminal of the users can indicate the current position of the users in the emergency state for a long time, so search and rescue personnel can conveniently carry out search and rescue work.

Description

technical field [0001] The present invention relates to the communication field, in particular to the mobile terminal technology in the communication field. Background technique [0002] In today's society, mobile terminals such as mobile phones have almost become necessities of life, have a high penetration rate, and become convenient tools to meet personal communication needs. [0003] At present, the structure of mobile terminal (i.e. mobile phone) is as follows: figure 1 As shown, it usually includes a Subscriber Identity Module (Subscriber Identity Module, referred to as "SIM") card and a SIM controller module connected thereto, a power control module, a baseband chip, a radio frequency module, an antenna, a display module, a storage module, an audio module, Man-machine interface module, etc. [0004] The SIM card is a user information card that stores user information; the SIM controller connects the SIM card and the mobile phone so that the two can operate with each...
