Abstract

The invention provides an LBS (location based service)-based reachable area determining method and LBS-based reachable area determining equipment. According to the embodiment of the invention, retrieval track points are obtained by retrieval on a reachable track of a to-be-retrieved position according to retrieval time information, wherein the value of the time from the to-be-retrieved position to the retrieval track points is smaller than or equal to a reachable time threshold value indicated by the retrieval time information, so that a reachable area can be determined for a client according to the retrieval track points. According to the technical scheme provided by the invention, the retrieval track points reachable from the to-be-retrieved position within a time range can be obtained. Thus, the reachable area can be determined for the client according to the retrieval track points for further detailed retrieval in the reachable area, and the problem that a retrieval result cannot be reached or is difficultly reached from the to-be-retrieved position due to certain traffic jams in the prior art can be avoided, so that the retrieval reliability is improved.

Description

【Technical field】 [0001] The present invention relates to a location service (Location Based Service, LBS) technology, in particular to a location based service (Location Based Service, LBS) retrieval method and device. 【Background technique】 [0002] With the development of communication technology, more and more functions are integrated into the terminal, so that more and more corresponding application programs are included in the system function list of the terminal. Some applications involve location services (Location Based Service, LBS), also known as location services, such as Baidu Maps. In the existing LBS, based on the map platform or web page search, the client can be provided with search results within a circular area with the location to be searched as the center and a specified distance as the radius. [0003] However, due to some traffic barriers, such as rivers, lakes or mountains, etc., it is impossible or difficult to reach the retrieval results from the l...
