Embodiment Construction

[0069] With the popularization of Wireless fidelity (Wi-Fi) technology, many mobile phones, personal digital assistants, and notebook computers on the market now have Wi-Fi devices as standard equipment. Users can use this The Wi-Fi device connects to hotspots near the location anytime and anywhere to realize wireless Internet access. The present invention compares the hotspot information detected by these Wi-Fi devices with the location information of the existing hotspots in the location database, so as to calculate and record the hotspots newly added, eliminated or moved in the same area. positioning information. In addition, the present invention can also combine the base station information detected by wireless communication devices such as mobile phones to compare with the existing base station location information in the location database, thereby assisting the device in estimating the hotspot location information. The present invention is a set of positioning informat...

Abstract

The invention relates to a positioning information update method and system and used computer program product. Firstly, signal strength value of a plurality of signal sources at the periphery of a radio communication device and identification information are detected; wherein the signal sources includes at least one known signal source and at least one unknown signal source. Then positioning position table is searched to find positioning information corresponding to the identification information of each known signal source. And then the positioning information of the unknown signal source iscalculated according to the signal strength value and positioning information of the known signal source and the signal strength value of the unknown signal source. And finally the identification information of the unknown signal source is record in the positioning position table. Thus, accuracy of the positioning information and completeness of the positioning position table can be improved, andcost for updating positioning information can be reduced.

Description

technical field [0001] The present invention relates to a positioning method and system, and in particular to a positioning information updating method, system and computer program product used. Background technique [0002] Currently, most positioning devices (or navigation devices) on the market adopt the technology of the Global Positioning System (GPS). The Global Positioning System is a combination of satellite technology and wireless communication technology, which can provide users with more accurate positioning, speed and time information. With the advancement of satellite technology, the GPS has gradually developed from the early military use to general life applications, the most common of which is for target positioning and navigation. [0003] The positioning and navigation of the Global Positioning System rely on the cooperation between satellites, positioning devices and navigation software to operate smoothly. However, the positioning device often cannot rec...
