Position information acquisition method based on calling, device and system

Abstract

The invention discloses a position information acquisition method based on calling, a device and a system. The method comprises steps that when a presently-dialed telephone number is detected by a first terminal to be a preset telephone number, the position information of the first terminal is acquired; a message containing the position information is sent to the service equipment, so a second terminal is made to acquire the position information of the first terminal through the message sent by the service equipment. Through the method, the precise position information of the first terminal can be automatically sent to the second terminal on the condition that a system in the prior art is not changed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for acquiring location information based on calls. Background technique [0002] When a mobile terminal user is in danger, such as a fire at home, or casualties when going out, or an emergency such as personal or property danger, the user generally first calls the police for help. In the sending state, users generally cannot clearly state their location information. Even under some extreme conditions, users do not know their specific location at all, which brings great difficulties to rescue, and sometimes even misses the best rescue time. Severe personal or property damage. [0003] In the prior art, it is provided to determine the location of the caller by tracking the location of an alarm or a help call, but this method of location tracking can only be performed based on the base station provided by the operator. Such as figure 1 A...

AI Technical Summary

Problems solved by technology

[0004] pass figure 1 Although the method can realize caller-based positioning when the system connection is good, in general, only a relatively large range can be obtained, and the specific location of the caller cannot be accurately located, so it cannot be timely rescue

Moreover, since different operators have different interfaces, the alarm system must be connected to each operator individually, which not only requires high development costs, but also makes system maintenance more difficult as the number of suppliers increases. Even, in some networks In unstable or areas with few base stations, the above implementation process will be more difficult due to unstable signals, resulting in missing the best rescue time
