Alternatively, if the common synchronization signal sending time test terminal of above-mentioned anolog base station 10 is unknown, terminal is tested
20 abandon means within the unit interval by invalid/abnormal measurement of predetermined quantity resists.
When anolog base station 10 works in special synchronous pattern, the same known technology of signal strength measurement of terminal 20 is tested,
Do not repeating herein.
In the present embodiment, anolog base station and test terminal are by conventional mobile terminal（First mobile terminal, the second movement
Terminal）Constitute, but also need to certain Software adapting, it is described below：
Under TDD mode, the reforming content for realizing anolog base station based on the first mobile terminal includes：Make anolog base station
While persistently receiving existing network base station synchronization signal, common synchronization signal can be sent in precalculated position；To the second movement eventually
Realize that the transformation of test terminal includes in end：Test terminal is set to monitor the public affairs from existing network base station and anolog base station in diverse location
Common synchronizing signal.Under TDD mode, retrofit work amount to the first mobile terminal and the second mobile terminal is simultaneously little.
To realize this TDD mode, the transformation of anolog base station requires that the first mobile terminal can possess certain time
Two moment at interval are received and sent respectively, and this belongs to known technology for conventional terminal；Test changing for terminal
Make and require that the second mobile terminal can receive measurement in diverse location and come from different districts（Existing network base station and anolog base station）Public affairs
Synchronizing signal altogether, this is to require that conventional terminal implements signal reception in different time position, and carries out ionization meter, this for
Belong to for conventional terminal and repeat this function of having supported in diverse location, still fall within known technology.
Under semiduplex mode, the reforming content for realizing anolog base station based on the first mobile terminal includes：Make anolog base station can
Receive existing network base station synchronization signal, and timesharing sends common synchronization signal；Changing for test terminal is realized based on the second mobile terminal

Mobile terminal can differentiate common synchronization signal validity when synchronizing signal reception；Processing method is as follows：
A, the second mobile terminal are implemented common synchronization signal and received；
B, judge the common synchronization signal quality whether be more than pre-determined threshold Th1It is then to be considered as and effectively continue executing with；
It is no, then it is invalid, abandon this common synchronization signal, return to step A；
The signal quality includes signal to noise ratio, Signal to Interference plus Noise Ratio, and acquisition modes are known technology；Pre-determined threshold is empirical value,
Span -6 ~ 10dB；
Optionally, it may also include：
B ', the average signal quality difference judged in the common synchronization signal quality and preset time are less than pre-determined threshold
Th2It is then to be considered as and effectively continue executing with；It is no, then it is invalid, abandon this common synchronization signal, return to step A；
20~100ms of the preset time span；0 ~ 5dB of pre-determined threshold span；

In the difference of cell ID and working frequency points, without any transformation action.It can be seen that, it is special same relative to first two mode of operation
Zero transformation of test terminal can be achieved in step mode on the premise of suitable anolog base station side retrofit work amount, generally speaking, can
The minimum transformation demand to anolog base station and test terminal is realized, can significantly simplify engineering difficulty.
To realize this special synchronous pattern, the transformation of anolog base station require the first mobile terminal set up it is lasting it is predetermined specially
With service connection, realize dedicated channel（Here dedicated channel is preferably the poor throughput business such as speech, web page browsing, so as to
Reserve idle period）It is synchronous send downlink synchronous signal in precalculated position while keep, equivalent to requiring terminal just
While normal business is carried out, section at one's leisure（That is, the period beyond the period shared by dedicated service）Additionally sent, this for
It is similar to service concurrence demand for conventional terminal, in the transmitting-receiving demand of different time, it can be achieved based on prior art.
