That is, when it is determined that the radio frames number for the time-division wireless signal itself launched reaches given threshold, mould
Intending test terminal is needed again according to base during the signal of the cell, and base is calibrated when launching its own signal.
Wherein, the given threshold can be adjusted according to actual conditions；For example, when to the synchronous required precision of signal compared with
Gao Shi, the given threshold could be arranged to relatively small numerical value, when the required precision to signal synchronization is relatively low, institute
State given threshold and could be arranged to of a relatively high numerical value, the embodiment of the present invention is not limited in any way to this.
Step 206：Base carries out the transmitting of wireless Time Division signal when simulation test terminal is launched according to original signal.
Specifically, base can be simulation test terminal described in step 203 according to cell during original signal transmitting
Base during signal after base is calibrated during signal, or or step 204 described in simulation test terminal itself it is raw at random
Into signal transmitting when base.
The embodiment of the present invention three provides a kind of signal processing method based on simulation test terminal, and the simulation test is whole
End can be carried out certainly in the time-division wireless signal of cell where searching itself according to base during the signal of the time-division wireless signal
The calibration of base when body signal is launched, and then base carries out the transmitting of wireless signal when being launched according to the signal after calibration, is come with this real
It is now synchronous with the signal of existing network network, so as to solve lab simulation signal source present in prior art can not realize with it is existing
The problem of precise synchronization of time division communication system, improve the synchronous effect of signal.
Further, since the simulation test terminal generally can be in existing traditional terminal device, such as mobile phone, tablet personal computer, PDA
Formed Deng on the basis of, and when not searching cell time-division wireless signal, can be according to the when base create-rule of setting, random generation
Base during signal transmitting needed for itself, and base when launching according to the signal of itself generation, carry out the hair of corresponding time-division wireless signal
Penetrate, therefore can further improve the synchronous effect of signal and flexibility on the basis of reducing simulation signal generator and taking volume.
