Abstract
The invention relates to the technical field of a wireless communication network, specifically to a method for locating wireless local area network AP. A relative simple location mode in the method is the location based on AP strength, and simultaneously, the method is combined with field intensity location of RSSI. The method is simple in operation and is a new practical location method. In this way, the method could give play to a location advantage of the AP to the largest extent. The method of the invention saves network cost, increases locating efficiency and accuracy, and reduces the operation cost in a whole locating process.
Description
Technical field
The present invention relates to cordless communication network technical field, refer more particularly to the method for a kind of wireless local area network AP location.
Background technology
The wireless location technology of usual employing mainly contains 1) based on radio wave propagation time (TOA): require that base station and mobile terminal have point-device clock, and the both sides of receiving and transmitting signal can realize precise synchronization: 2) based on radio wave propagation time difference (TDOA): this method reduce time synchronized requirement, but, still require high to time precision, and extremely short time error will cause larger position error; 3) based on Radio wave incident angle (AOA): the method equipment needed thereby is complicated, is difficult in the application be suitable for; 4) unit marks (Containment): the method can only navigate to the scope of a honeycomb or sector, and positioning precision is lower; 5) based on signal strength signal intensity (RSS): can mobile terminal be extrapolated by measuring the signal strength signal intensity received.
The method of a kind of wireless local area network AP location that the present invention relates to, locate mode fairly simple in the method is exactly the location based on AP intensity, and get up with the field intensity positioning combination of RSSI, the method is simple to operate simultaneously, a kind of new localization method practical again.We can play the detent edge of AP to greatest extent like this, save the cost of network, improve efficiency and the accuracy of location, reduce the operating cost in whole position fixing process.
Summary of the invention
In order to overcome the defect existed in background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of method of wireless local area network AP location, the steps include:
(1), after starting, equipment energising carries out self-inspection, to guarantee normal operation;
(2) initialization, positions differentiation to the region at WLAN (wireless local area network) place, determines the analog signal of diverse location point;
(3) connect WLAN (wireless local area network), the field intensity positioning combination of the system data of wireless local area network AP and RSSI is got up;
(4) preliminary treatment, utilize system data function, obtain and the mobile site added as having wireless receiving and transmitting, determine the analog signal of diverse location point, by station field signal, between website with AP, constantly contraposition is connected, certification, produce new SIB, and contrast with the analog signal of diverse location point, preliminary treatment is carried out to data;
(5) upgrade system information, the data that each local area network (LAN) detects all can contrast with system data, choose information more accurately, and upgrade system information;
(6) according to AP field intensity location, utilize software test AP field intensity, obtain signal strength signal intensity, coupling system data and location probabilistic algorithm, draw and specifically locate conclusion.
Described AP system information more New function and RSSI locate mode combines.
