Abstract

The invention discloses a method for positioning a mobile terminal which is not connected with an Internet. The mobile terminal which is not connected with the Internet, at least three wireless access points, a wireless controller and a positioning server are used in the method. The method comprises the following steps: a WIFI (Wireless Fidelity) holding signal containing the identity authenticating information of the mobile terminal is transmitted to each wireless access point by the mobile terminal which is not connected with the Internet through a WIFI transmitter thereof in a unidirectional way; the received WIFI holding signal is transmitted to the positioning server by each wireless access point through the wireless controller; the identity of the mobile terminal is confirmed by the positioning server through the identity authenticating information of the mobile terminal, and WIFI real-time positioning is carried out on the mobile terminal through the signal intensity and the signal arrival time difference of the WIFI holding signal which is received by each wireless access point. Unidirectional positioning can be carried out on the mobile terminal which is not connected with the Internet on the basis of the existing WIFI network.

Description

To the method that mobile terminal of connecting Internet does not position
Technical field
The present invention relates to the method to the mobile terminal of connecting Internet does not position.
Background technology
Real-time positioning system (WiFi RTLS) has had related application, mobile terminal can position by WIFI network, but the location of mobile terminal needs itself and WAP (wireless access point) to bind, mobile terminal positions in the situation that not binding WAP (wireless access point), also there is no at present correlation technique.
Summary of the invention
The object of the present invention is to provide a kind ofly to the method that mobile terminal of connecting Internet does not position, it can be on the basis of existing WIFI network, and the mobile terminal of connecting Internet is not carried out to unidirectional location.
For achieving the above object, technical scheme of the present invention is that design is a kind of to the method that mobile terminal of connecting Internet does not position, and comprises the not mobile terminal of connecting Internet, at least three WAP (wireless access point), wireless controller, and location-server;
Described not connecting Internet state the WIFI inhibit signal that mobile terminal comprises mobile terminal authentication information by its WIFI reflector to each WAP (wireless access point) unidirectional emission;
Each wireless access WIFI inhibit signal receiving of naming a person for a particular job passes to location-server by wireless controller;
Location-server is by mobile terminal authentication validation of information mobile terminal identity, and the signal strength signal intensity of the WIFI inhibit signal receiving by each WAP (wireless access point) and signal step-out time, and to this mobile terminal, WIFI locates in real time.
Preferably, described WIFI reflector is with the frequency transmitting WIFI inhibit signal of 1Hz, and transmitting power is 50-100 milliwatt.
Preferably, described WAP (wireless access point) is anchor node.
Preferably, described mobile terminal is provided with WIFI inhibit signal frequency control module and WIFI inhibit signal strength control module.
Preferably, described location-server is provided with mobile terminal authentication module and the real-time location Calculation module of WIFI.
Preferably, the real-time location Calculation module of described WIFI comprises WIFI inhibit signal frequency identification submodule, WIFI inhibit signal intensity recognin module and WIFI inhibit signal step-out time recognin module.
Advantage of the present invention and beneficial effect are: provide a kind of to the method that mobile terminal of connecting Internet does not position, it can be on the basis of existing WIFI network, and the mobile terminal of connecting Internet is not carried out to unidirectional location.And in position fixing process, mobile terminal does not need to bind WAP (wireless access point).
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
The concrete technical scheme of implementing of the present invention is:
As shown in Figure 1, a kind of to the method that mobile terminal 1 of connecting Internet does not position, comprise the not mobile terminal 1 of connecting Internet, at least three WAP (wireless access point) 2, wireless controller 3, and location-server 4;
Described not connecting Internet state the WIFI inhibit signal that mobile terminal 1 comprises mobile terminal 1 authentication information by its WIFI reflector to each WAP (wireless access point) 2 unidirectional emission;
Each WAP (wireless access point) 2 passes to location-server 4 by the WIFI inhibit signal receiving by wireless controller 3;
Location-server 4 is confirmed mobile terminal 1 identity by mobile terminal 1 authentication information, and the signal strength signal intensity of the WIFI inhibit signal receiving by each WAP (wireless access point) 2 and signal step-out time, and to this mobile terminal, 1WIFI locates in real time.
Described WIFI reflector is with the frequency transmitting WIFI inhibit signal of 1Hz, and transmitting power is 50-100 milliwatt.
Described WAP (wireless access point) 2 can be anchor node.
Described mobile terminal 1 is provided with WIFI inhibit signal frequency control module and WIFI inhibit signal strength control module.
Described location-server 4 is provided with mobile terminal 1 authentication module and the real-time location Calculation module of WIFI.
The real-time location Calculation module of described WIFI comprises WIFI inhibit signal frequency identification submodule, WIFI inhibit signal intensity recognin module and WIFI inhibit signal step-out time recognin module.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
