Method and device of determining business district where user is located

Abstract

The embodiment of the invention provides a method and a device of determining a business district where a user is located. The method comprises: acquiring real-time geographic location information of the user, and carrying out address encoding on the geographic location information to determine an address code of a real-time geographic location of the user; determining address code regions, which are in a plurality of directions and adjacent to the address code of the real-time geographic location of the user, on the basis of a location range of a predetermined distance; acquiring information of at least one business district in the address code regions in the plurality of directions; determining the business district, to which a distance is shortest from the real-time geographic location of the user, according to the acquired information of the at least one business district and acquiring geographic location range information of the business district; and judging whether the user is in a geographic location range of the business district on the basis of the real-time geographic location information of the user and the geographic location range information of the business district. Through the method, the business district, to which the distance is shortest from the real-time geographic location of the user, can be accurately determined.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for determining a business district where a user is located. Background technique [0002] With the continuous development of computer technology, more and more e-commerce platforms and e-commerce-related businesses and information have entered people's daily life and work. Therefore, more and more advertisers push Advertising, in the prior art, often obtains the user's real-time location through the user's IP (Internet Protocol, a protocol for interconnection between networks) address and GPS (Global Positioning System, Global Positioning System), and performs advertisement delivery according to the user's real-time location , which is one of the trends in online advertising. [0003] However, the accuracy of advertisement placement is low only by using the user's coordinate information. Therefore, it is necessary to convert the user's coordinate informati...

Problems solved by technology

[0005] In the current existing technology, most feasible real-time location positioning methods for users use the user's IP address, mobile phone base station location information, and GPS location. By directly using these location information to convert the user's business district, there are often inaccurate positioning, Calculation time-consuming advanced problems

Using IP addresses to map business districts requires maintaining the correspondence between IP addresses and geographic locations as well as the mapping relationship between geographic locations and business districts. If the mapping relationship is not updated in time, it will easily lead to inaccurate user location mapping, resulting in inaccurate positioning; Using GPS positioning, it is necessary to calculate the dist
