Embodiment Construction

[0046] in figure 1 , A system 100 is provided, which includes a mobile device 102, a positioning engine 104, a database server 106, a merchant portal 108, and a shopper portal 110.

[0047] The operation of the system 100 is as follows.

[0048] First, the user downloads and installs it in the form of a mobile application on the mobile device 102 via a telecommunications link such as a third-generation (3G) telecommunications network, a general packet radio service (GPRS) data link, etc. ("telecommunications link") Client-based software. The mobile device 102 may be a wireless fidelity (WiFi) function smart phone, a touch screen tablet, a notebook computer, a netbook computer, etc. The mobile application is configured to exchange data with the database server 106 and the positioning engine 104. The mobile application is used to detect the location of the mobile device 102 inside the building.

[0049] When activated at any location of the building, the mobile application uses the ...

Abstract

A method and apparatus for determining location information of a position in a multi-storey building, the method comprising: retrieving observation data comprising observed addresses and corresponding observed received signal strengths of wireless access points detected at the position from a memory; retrieving, for each storey of the building, a radio map comprising a plurality of location points in the respective storey of the building from a database; selecting one or more location points comprising the observed addresses from the radio map; determining a storey estimate of the position by calculating a sum probability for each storey of the building; and setting the storey estimate as the storey of the building having highest value of the calculated sum probability.

Description

Technical field [0001] The invention relates to a method for determining location information of a location in a multi-story building. Background technique [0002] In recent years, with the widespread use of global positioning system (GPS) functions in mobile devices, especially smart phones, location-based applications and services have become increasingly popular. However, because GPS satellite signals are not detectable when indoors, once the mobile device enters the building's interior, the GPS function's low-cost solution with accurate positioning and convenience is lost. [0003] In today's cities, people spend a lot of time indoors, such as in shopping malls, airports, office buildings, hospitals, and industrial plants, which require an extension of indoor positioning capabilities. Having accurate indoor positioning capabilities can allow companies to improve indoor workflows, processes, safety management, asset and personnel tracking, customer satisfaction, and the implem...
