A call processing method, mobile terminal and server

Abstract

The embodiment of the invention discloses a call processing method, a mobile terminal, and a server. The call processing method comprises: when a phenomenon that a mobile terminal dials an emergency call is monitored, information of a current base station where the mobile terminal carries out registration is reported to the server; auxiliary positioning data, sent by the server, of the current base station are received; according to the auxiliary positioning data of the current base station, a positioning data signal of the mobile terminal is searched and is processed by demodulation, and then the processed signal is fed back to the server, so that the server determines the geographical position of the mobile terminal according to the demodulated positioning data; and the geographical position of the mobile terminal is obtained and is sent to a terminal of at least one emergency contact associated with the mobile terminal. Therefore, precise positioning of the mobile terminal can be realized; and the call processing efficiency and the terminal positioning accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a call processing method, a mobile terminal and a server. Background technique [0002] With the rapid development of mobile communications, mobile terminals are widely used. When in danger, people are often used to calling for help through mobile terminals to obtain help. Mobile terminals generally have basic functions such as phone calls and short messages. Even when a Subscriber Identity Module (SIM, Subscriber Identity Module) is not inserted in the mobile terminal, it can also support emergency calls, such as 110, 119, etc. [0003] At present, most mobile terminals can support Global Positioning System (GPS, Global Positioning System) positioning technology, so when in danger, the user can start the GPS positioning function of the mobile terminal to search and locate the satellite to obtain the current position. Geographical location information, and then the user ma...

Problems solved by technology

[0003] At present, most mobile terminals can support Global Positioning System (GPS, Global Positioning System) positioning technology, so when in danger, the user can start the GPS positioning function of the mobile terminal to search and locate the satellite to obtain the current position. Geographical location information, and then the user manually edits the obtained geographic location information and sends it to the emergency contact in the form of SMS, MMS or instant messaging software. However, in special scenarios, such as poor GPS signal or no GPS signal (the woods in the suburbs can easily block the GPS signal), the GPS positioning function of the mobile terminal may be invalid or need to wait for the signal to be better before using the GPS positioning function, so that the user cannot quickly obtain the current geographic location information, applicability is not high, and when the user is in a dangerous situation, the geographic location information needs to be sent to all emergency contacts at the first time, so as to get more help in the shortest time, and the current geographic location information is manually edited by the user If it is sent again, it takes a lot of time and reduces the efficiency of call processing

However, if the information of the registered base station is directly obtained for positioning, the positioning accuracy of the terminal is not high due to the large deviation.
