Below will explain content of the present invention through embodiment.Yet embodiments of the invention are not to need can implement like the described any environment of embodiment, application or mode in order to restriction the present invention.Therefore, be merely explaination the object of the invention about the explanation of embodiment, but not in order to direct restriction the present invention.What need explanation is in following examples and the diagram, to omit and do not illustrate with the non-directly related element of the present invention.
Fig. 1 shows one first embodiment of the present invention, and it describes a kind of test macro 1.Test macro 1 comprises a control switch 11, one first base station simulator 13, one second base station simulator 15, a signal measuring apparatus 17 and a signal generator 19.As shown in the figure, first base station simulator 13, second base station simulator 15, signal measuring apparatus 17 and signal generator 19 link with control switch 11 respectively.Wherein, test macro 1 sees through control switch 11 and a device 2 to be measured is set up network connectivity, makes test macro 1 see through control switch 11 and receives the wireless network signal of device 2 to be measured, and test.Palpus special instruction person, employed control switch 11 is the interchangers (switch) that possess the processing operations ability among first embodiment, implements also can it be subdivided into a Control Server and an interchanger in aspects in other.
Then please be simultaneously with reference to figure 2.At first; The setting work that test macro 1 palpus is correlated with to the environment of desire test; Then control switch 11 and transmit acceptance test setting 110 to first base station simulators 13 and second base station simulator 15 simultaneously; Its purpose makes the follow-up reception of base station simulator and handles the wireless network signal that is transmitted by device 2 to be measured in the setting that base station simulator is received signal correction.Need specify here; The acceptance test that control switch 11 is sent to first base station simulator 13 and second base station simulator 15 among Fig. 2 is set 110 and can be the same signal that sends simultaneously; Use the meaning of two signal line to be in the diagram; Emphasical signal is to deliver to the different base station simulator by same control switch branch, and it is not in order to the quantity of restricting signal and the mode of transmission.Then; Control switch 11 transmits testing setup 112 to signal measuring apparatus 17; Likewise, its purpose is signal measuring apparatus 17 is transmitted the setting of signal correction, the wireless network signal that signal measuring apparatus 17 follow-up measurements are transmitted by device 2 to be measured.
After the setting of aforementioned test macro 1 is accomplished, just carry out the wireless signal measurement of device 2 to be measured earlier by first base station simulator 13.Particularly; Test macro 1 is after accomplishing aforementioned setting; See through control switch 11 earlier and set up network connectivity, see through control switch 11 by first base station simulator 13 more immediately, transmit one first channel setting signal 130 to device 2 to be measured with device 2 to be measured; Make device 2 to be measured according to the first channel setting signal 130, carry out communication in one first channel (not illustrating) and test macro 1.
Wherein, what must specify is, but 2 in test macro 1 and device to be measured have the channel scope of a communication; And, will make the test process inefficiency that seems if each frequency is all tested in the channel scope, therefore; For shortening testing process; But just get the lowest center frequency of the channel scope of communication, middle centre frequency and the highest centre frequency, and test, thus in above-mentioned three kinds of frequencies; Just can omit the loaded down with trivial details property that each frequency all must be tested in the channel scope, and reach the purpose of the whole channel scope of test simultaneously.And in present embodiment, aforesaid this first channel is the lowest center frequency.
Then; After device 2 affirmations to be measured and first base station simulator 13 are to carry out communication through this first channel; First base station simulator 13 just begins to send a plurality of first test messages 132 to device 2 to be measured; And device 2 to be measured is just responded a plurality of first response message 20 according to these first test messages 132 in regular turn, makes test macro 1 carry out signal testing.Furthermore, control switch 11 just is sent to first base station simulator 13 and signal measuring apparatus 15 with first response message 20 simultaneously after first response message 20 that receives device 2 to be measured.And after first base station simulator 13 receives first response message 20 in regular turn, just can calculate one first bit error rate (bit error rate) according to a plurality of first response message 20; Simultaneously, 17 of signal measuring apparatus can be judged one first signal quality of device 2 to be measured according to first response message 20.
