    • The present disclosure relates to providing a positioning service by managing a plurality of peripheral wireless LAN signals. The positioning service system collects peripheral wireless LAN radio signals by scanning peripheral access points (APs), stores AP information of each of peripheral wireless LAN radio signals in each lattice cell of a database. When a positioning request signal is received from a terminal, a positioning server of the positioning service extracts AP identification information from included in the peripheral wireless LAN radio signal received from the terminal. By using the extracted AP identification information, the positioning server selects from the database the corresponding lattice cell matching to the stored AP identification information of each of the peripheral wireless LAN radio signals pre-stored. And the positioning server estimates location information of the selected corresponding lattice cell as location information for the terminal.
    • 本公开涉及通过管理多个外围无线LAN信号来提供定位服务。 定位服务系统通过扫描外围接入点(AP)来收集外围无线LAN无线电信号,将每个外围无线LAN无线电信号的AP信息存储在数据库的每个格子单元中。 当从终端接收到定位请求信号时,定位服务的定位服务器从包括在从终端接收的外围无线LAN无线电信号中提取AP识别信息。 通过使用提取的AP识别信息,定位服务器从数据库中选择与存储的每个外围无线LAN无线电信号的存储的AP标识信息匹配的对应的格子单元。 并且定位服务器估计所选择的相应格子单元的位置信息作为终端的位置信息。
