Step 301, the first communication radio frequency link transmissions signal, the second communication radio frequency link transmissions signal,
In the case that the first GPS radio frequency link receives the progress simultaneously of the first positioning signal, the first communication radio frequency link is determined
It is poor with the working frequency range of the second communication radio frequency link.
In embodiments of the present invention, step 301 is referred to above-mentioned steps 101, no longer superfluous herein in order to avoid repeating
It states.
Step 302, in the difference of the working frequency range of the first GPS radio frequency link and the working frequency range difference in default model
In the case where in enclosing, first positioning signal is abandoned, and based on the first communication radio frequency link and/or second communication
Radio frequency link is positioned.
In embodiments of the present invention, the first communication radio frequency link transmissions signal, the second communication radio frequency link transmissions signal,
First GPS radio frequency link receives in the case that the first positioning signal carries out simultaneously, if the first communication radio frequency link and described the
The working frequency range of two communication radio frequency links is poor, and it is poor to make with the working frequency range of the first GPS radio frequency link, and difference is in above-mentioned preset range
It is interior, illustrate, in the case where the first communication radio frequency link and the second communication radio frequency link emit signal simultaneously, is penetrated to the first GPS
Frequency link is caused with interior interference, can use the first communication radio frequency link or the second communication radio frequency link, alternatively, the first communication
Radio frequency link and the second communication radio frequency link are positioned, and can be positioned to avoid with the first positioning signal after interior interference
The inaccurate problem of caused positioning, can be by the first communication radio frequency link and the leakage of the second communication radio frequency link transmissions to positioning
Interference is minimized, and is able to ascend the accuracy of positioning.
It is recorded specifically, above-mentioned steps 302 are referred to the related of above-mentioned steps 102, it should be noted that can pass through
First communication radio frequency link and/or the second communication radio frequency link determine the position coordinates of mobile terminal by least three base stations,
To realize the positioning to mobile terminal.
In embodiments of the present invention, optionally, referring to shown in Fig. 8, Fig. 8 show provided in the embodiment of the present invention based on
The flow chart that first communication radio frequency link and/or the second communication radio frequency link are positioned.It is described to be penetrated based on first communication
Frequency link and/or the second communication radio frequency link are positioned, and may include:
Step 3021, pass through the first communication radio frequency link and/or the second communication radio frequency chain road direction at least three
