Before testing, background terminal stores system configuration information, this system configuration information comprises: the file name formats (default format: RIRFIL00-0000000XXX) of the IP address of base station controller, the storage directory of spectrum measurement log file, spectrum measurement record, also can comprise user name, password etc.
101, background terminal determines the configuration information of tested hardware according to the hardware configuration information obtained from base station controller;
Specifically, 101 by such as under type realization:
Background terminal can adopt Telnet (TELNET) agreement to send the instruction of inquiry hardware test information to base station controller, the database that base station controller will be retrieved in its memory after receiving this instruction, and following hardware configuration information is turned back to background terminal.

Table one
| True cell is numbered | Channel group number | Carrier frequency is numbered | Maximum transmission power | Virtual subdistrict is numbered |
| QHG369C | CHGR0 | RXOTX-392-0 | 47 | 369C_0 |
| QHG369C | CHGR1 | RXOTX-392-1 | 47 | 369C_1 |
102, background terminal receives the appointment frequency point information of user's input, and according to the virtual parameter information that appointment frequency point information and the configuration information of user's input generate, then after adding this virtual parameter information to virtual subdistrict defined instruction, be sent to base station controller.
Wherein, virtual parameter information specifically comprises: virtual subdistrict broadcast channel transmission frequency (frequency point information of namely specifying), virtual subdistrict transmitting power and forbid service access cell;
In preferred version, above-mentioned frequency point information of specifying should be any frequency in 76-94 frequency, 1-19 frequency;
For guaranteeing that intermodulation product level maximizes, virtual subdistrict transmitting power is defined as the maximum transmission power that carrier frequency is supported.Therefore, in preferred version, virtual subdistrict transmitting power is the maximum transmit power of carrier frequency in configuration information.
Lower mask body is introduced in the present embodiment, and virtual subdistrict broadcast channel transmission frequency is preferably the principle of any frequency in 76-94 frequency, 1-19 frequency.
Due in prior art; by the restriction of the actual frequency be configured in true cell; be difficult to the Intermodulation Interference of test cell on desirable frequency; and for guaranteeing that inter-modulated signal correctly detects; in embodiments of the present invention; combined with virtual community can feature, the restriction of the actual frequency be configured can be departed from prior art, order intermodulation products is fallen into receiver uplink band.The principle specifically arranging frequency range is as follows:
In gsm system, uplink band is 890-909MHz, and band downlink is 935-954MHz, and Duplex Spacing is 45MHz.Be below intermodulation frequency computing formula (wherein f1 is the frequency of downstream signal 1, f2 is the frequency of downstream signal 2):
3 rank intermodulation frequency fIM3=2f1-f2
5 rank intermodulation frequency fIM5=3f1-2f2
As calculated, 3 rank intermodulation frequencies fall into 916-973MHz, do not fall into upstream band; 5 rank intermodulation frequencies fall into 897-992MHz, and part falls into upstream band.Therefore, the lowest-order intermodulation product falling into uplink band is 5 rank intermodulation products.As shown in Figure 3.
For guaranteeing that 5 rank intermodulation product level maximize, 5 rank intermodulation product frequencies need be made to be positioned at uplink band high-end.According to 5 rank intermodulation frequency computing formula, when two frequency intervals transmitted are 15MHz, 5 rank intermodulation frequency fIM5=3f1-2f2=3 (f2-15)-2f2=f2-45MHz, and f2 up=f2-Duplex Spacing=f2-45MHz, illustrate when two frequency intervals transmitted are 15MHz, 5 rank intermodulation products and upward signal are with frequently.Therefore, as long as to be positioned at band downlink high-end for transmit interval 15MHz and higher the transmitting of frequency of two virtual subdistricts, just can guarantee that intermodulation product frequency is positioned at uplink band high-end.Proposed arrangement f1 is 950-954MHz, f2 is 935-939MHz, is equivalent to No. 76-94 in GSM, 1-19 frequency.Such as guaranteeing intermodulation product frequency and stabilization of level; specifically set up 2 signal sources of launching continually and steadily; implementation method is the broadcast channel carrier frequency carrier frequency of 2 in true cell being defined as respectively 2 virtual subdistricts, and these 2 communities are set to forbid service access.The broadcast channel transmission frequency of 2 virtual subdistricts is set to No. 94 and No. 19 frequencies respectively.If No. 94 frequency interference obviously exceed the interference of other frequencies in real network, also slightly low frequency can be set, as No. 93 and No. 18 frequencies.
103, base station controller receives the virtual subdistrict defined instruction from described background terminal, and according to the test instruction (as out code, carrier frequency and community locking relation alteration command) of virtual parameter information (virtual subdistrict broadcast channel transmission frequency, virtual subdistrict transmitting power and forbid service access cell) and user for tested true cell is configured for the information generated of the virtual subdistrict that Intermodulation Interference is tested.
Wherein, this information generated can be specially: the carrier frequency numbering (i.e. in the configuration information of tested hardware, minimum and maximum carrier frequency is numbered) of virtual subdistrict Intermodulation Interference test, virtual subdistrict are numbered (being derived from configuration information), virtual subdistrict broadcast channel transmission frequency, virtual subdistrict transmitting power, forbidden service access cell;
Specifically, step 103 is by such as under type realization:
