Through the aforesaid operations of control centre, can realize the concentrating, monitor and move efficiently of the wireless external field environment built improved testing efficiency, strengthen the controllability of test process.
The embodiment of the invention can also be according to different test purposes; Construct multiple wireless test scene; Realize the switching of many scenes; And the network of considering different systems under different scenes to building the demand of external field environment, to satisfy test needs such as single GSM/TD network, GSM-TD mixed networking, GSM-TD interoperability.
For realizing above-mentioned purpose, can carry out following operation:
(1) passes through the parameter that control centre disposes each base station in the field testing environment.
All dispose the GSM/TD-SCDMA/TD-LTE/WLAN corresponding equipment on each site; Promptly; BTS (Base Transceiver Station, base transceiver station)/NodeB (Node B)/eNodeB (EvolvedNode B, evolved Node B)/AP (Access Point; Access point); By control centre be responsible for according to the degree of fitting algorithm confirm to obtain to simulate a certain scene the base station parameters such as station spacing, transmitting power and antenna gain that should use, and switching, power and the gain of control base station are with the simulation different scene.
(2) pass through the parameter that control centre adjusts antenna.
Each place, site all is provided with the antenna robot brain tool device of customization, in order to the attributes such as pattern (smart antenna, many antennas and polarization mode etc.), position, height and inclination angle of adjustment antenna, cooperates the adjustment that realizes coverage, adaptive different wireless scene.
(3) pass through the parameter that control centre adjusts the high-speed simulation device.
Particularly; Emulation to the high-speed mobile scene; The embodiment of the invention can be employed on each base station the variation that the mode that loads the high-speed simulation device remedies Doppler's expansion, reciprocity radio transmission effect when the terminal that low speed or middling speed are moved obtains with high-speed mobile.On the down direction, the high-speed simulation device produces high-speed mobile emulation wireless signal, and simulating high-speed moves institute and causes factors such as wireless signal Doppler frequency shift, Doppler's expansion, quick decline, and this high-speed simulation signal will be received in the terminal of low speed or middling speed.On the up direction, because the ability of base station correcting frequency offset is strong, so the radiofrequency signal that need not utilize high-speed simulation device processing terminal to send.
Control centre can unify control to all the high-speed simulation devices in the test environment of outfield, in real time to each high-speed simulation device output simulation velocity parameter, to change the high-speed simulation state of field testing environment.Particularly; The base station radio-frequency output connects the high-speed simulation device; The high-speed simulation device is according to the simulation velocity parameter of algorithm and control centre input, and high-speed mobile to the amplitude/phase/frequency influence factor of the wireless signal base station radio-frequency signal that is added to, is inserted the antenna-feedback system emission then.The high-speed simulation device is positioned at base station RRU (Radio RemoteUnit, the radio frequency remoto module) outside, and directly carries out the control of input parameter by control centre, can not impact the inside of base station structure.The down-conversion that the radiofrequency signal of base station output is at first passed through the high-speed simulation device; Become baseband signal; The simulation velocity parameter that is used to Self Control center input carries out expanding relevant processing with Doppler to baseband signal, and up-conversion is to band signal again, and is gone out by antenna transmission.Utilize the high-speed simulation device, can in small-scale wireless outfield, simulate the high-speed mobile scene, to support several scenes.
