Abstract: front page image
(EN)An embodiment of the present invention relates to a method for managing a peripheral wireless LAN signal and a device, an access point (AP), a positioning server, and a terminal for same. The system for managing a peripheral wireless LAN signal according to one embodiment of the present invention comprises: a database for storing each of lattice cells divided according to cell IDs, wherein each of the lattice cells are stored by being matched to a wireless LAN radio wave signal; a business AP for scanning peripheral APs in regular periods, and transmitting the peripheral wireless LAN radio wave signal received from the scanned peripheral APs; an AP managing device for match-storing, to a lattice cell comprising AP identification information, the AP identification information which is a parameter of the received peripheral wireless LAN radio wave signal, the parameter of the peripheral wireless LAN radio wave signal, as reference position information; and a wireless LAN-based positioning server for extracting the AP identification information from the parameter included in the wireless LAN radio wave signal received from the terminal, sorting the lattice cell having the AP identification information match-stored as the reference position information, and estimating position information of the corresponding lattice cell as position information of the terminal, when receiving a position request signal from the terminal.
(FR)Un mode de réalisation selon l'invention concerne un procédé pour gérer un signal de réseau local sans fil périphérique et un dispositif, un point d'accès (AP), un serveur de localisation et un terminal correspondant. Le système pour gérer un signal de réseau local sans fil périphérique selon l'invention comprend: une base de données pour stocker chacune des cellules élémentaires divisées en fonction des identifications de cellules, chacune des cellules élémentaires étant stockées par appariement avec un signal d'onde radioélectrique de réseau local sans fil; un point d'accès commercial pour balayer les points d'accès périphériques à des intervalles réguliers, et transmettre le signal d'onde radioélectrique de réseau local sans fil reçu depuis les points d'accès périphériques balayés; un dispositif de gestion des points d'accès pour stocker par appariement avec une cellule élémentaire comprenant les informations d'identification de points d'accès, les informations d'identification de points d'accès, c'est-à-dire, un paramètre du signal d'onde radioélectrique de réseau sans fil périphérique, le paramètre du signal d'onde radioélectrique de réseau sans fil périphérique, en tant qu'informations de position de référence; un un serveur de localisation fondé sur le réseau local sans fil pour extraire les informations d'identification de points d'accès à partir du paramètre inclus dans le signal d'onde radioélectrique de réseau local sans fil reçu depuis le terminal, trier les cellules élémentaires ayant des informations d'identification de points d'accès stockées par appariement en tant qu'informations de position de référence, et estimer les informations de position de la cellule élémentaire correspondante en tant qu'informations de position du terminal à réception d'un signal de demande de position émanant du terminal.
(KO)본 발명의 일 실시예는 주변 무선랜 신호를 관리하는 방법과 그를 위한 장치, AP, 측위 서버 및 단말기에 관한 것이다. 본 발명의 일 실시예는 셀 ID 별로 구분된 각각의 격자 셀을 저장하되, 상기 각각의 격자 셀에 무선랜 전파 신호를 매칭하여 저장하는 데이터베이스; 일정한 주기로 주변 AP(Access Point)를 스캔(Scan)하고, 스캔된 상기 주변 AP로부터 수신된 주변 무선랜 전파 신호를 전송하는 사업자 AP; 수신된 상기 주변 무선랜 전파 신호의 파라미터(Parameter)인 AP 식별 정보를 포함하고 있는 격자 셀에 상기 주변 무선랜 전파 신호의 파라미터를 참조 위치 정보(Reference Position)로서 매칭 저장하는 AP 관리 장치; 및 단말기로부터 측위 요청 신호를 수신하면, 상기 단말기로부터 수신한 무선랜 전파 신호에 포함된 파라미터 중 AP 식별 정보를 추출하고, 상기 AP 식별 정보가 참조 위치 정보로서 매칭 저장되어 있는 격자 셀을 선별하고, 해당 격자 셀의 위치 정보를 상기 단말기의 위치 정보로 추정하는 무선랜 기반 측위 서버를 포함하는 것을 특징으로 하는 주변 무선랜 신호 관리 시스템을 제공한다.
