Help-seeking method, device and system based on location based service

Abstract

Embodiments of the present invention disclose a help-seeking method, device and system based on a location based service, which relate to the field of location based service technologies. Help-seeking information sent by a first terminal is received, and a location area of the first terminal is determined according to the help-seeking information; the help-seeking information is sent to a second terminal located in the same location area as the first terminal; and response information fed back by the second terminal is received, and the response information is sent to the first terminal. The problem that, in the prior art, help-seeking information cannot be published in time when a user terminal needs help from another user terminal in the neighborhood of the user terminal in terms of geographic location is solved. The present invention may be applied in a mobile user terminal, for example, a smart phone terminal.
