Referring to Fig. 2, the method of disturbing in a kind for the treatment of facility provided for the embodiment of the present invention, dispose the first transceiver Radio1 and the second transceiver Radio2 of different working modes, wherein in described equipment, Radio1 is in the first mode of operation, and Radio2 is in the second mode of operation.Mode of operation can comprise GSM(Global System for Mobile Communications, global system for mobile communications) pattern, WCDMA(Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) pattern, WLAN(wireless local network, WLAN (wireless local area network)) pattern, BT(Bluetooth, bluetooth) pattern or GPS(Global Positioning System, global positioning system) pattern etc.In the embodiment of the present invention, once Radio1 and Radio2 are operated in adjacent or near frequency band, the transmitted signal of Radio1 will receive to the signal of Radio2 the signal that causes interference or Radio2 to send and can receive and cause interference the signal of Radio1, be subject to the situation of the interference of Radio1 for Radio2, described method specifically can comprise following operation:
Step 201: M the antenna that obtains Radio1 divides the isolation of N the antenna that is clipped to Radio2, and wherein, M is greater than 1 integer, and N is more than or equal to 1 integer;
In the embodiment of the present invention, the isolation of antenna refers to the ratio of the received power of the transmitting power of an antenna and another antenna, larger this antenna of the isolation of antenna is less for the interference of another antenna, for example, the isolation of 1 pair of antenna 2 of antenna is larger, the interference that 1 pair of antenna 2 of antenna is described is less, and so, M the antenna that obtains Radio1 divides the isolation of N the antenna that is clipped to Radio2 to comprise:

Mode 2: from M the antenna of Radio1, an antenna of random selection is as reference antenna, and the transmitting gain degree of unbalance of this reference antenna is decided to be to 0dB (being equivalent to real number value 1), the embodiment of the present invention is using first antenna in Radio1 as reference antenna, afterwards, determine the transmitting gain degree of unbalance of other antennas of Radio 1 with respect to this reference antenna, specifically can comprise: control described reference antenna and send measuring-signal with the 3rd transmitting power to Correspondent Node, and the 3rd received power of the described measuring-signal of reception that feeds back of received communication opposite end, m antenna controlling Radio1 sends measuring-signal with the 3rd transmitting power to Correspondent Node (as base station), the 4th received power of the described measuring-signal of reception of received communication opposite end feedback, calculate the ratio of the 4th received power and the 3rd received power, obtain the transmitting gain degree of unbalance Tm of m the antenna of Radio1, wherein, the value of m is 2 to M.
Further, in described transmitting gain degree of unbalance measuring process, the M of a Radio1 antenna can send the signal of equal-wattage simultaneously, or sends successively the signal of equal-wattage.Send the situation of the signal of equal-wattage for M the antenna of Radio1, the signal that each antenna sends can be quadrature at receiving terminal on certain dimension, on frequency or on the code territory, be for example quadrature, so that receiving terminal can be distinguished the signal from different antennae.
Further, the embodiment of the present invention is when specific implementation, can repeatedly adopt mode 1 or the described mode of mode 2 to obtain the transmitting gain degree of unbalance of m the antenna of a plurality of Radio1 in a period of time, and the mean value of the transmitting gain degree of unbalance of m the antenna of a plurality of Radio1 that this period is interior is finally as the transmitting gain degree of unbalance Tm of m the antenna of Radio1.
Here, the mean value of why usining in a period of time is as the transmitting gain degree of unbalance Tm of m the antenna of Radio1, for fear of antenna to be closed in follow-up M the antenna determine Radio1 according to this transmitting gain degree of unbalance Tm, and close describedly when the antenna of closing, constantly adjust the situation of antenna to be closed in M the antenna of Radio1.
Further, in configuration device during the M of Radio1 antenna, can pre-estimate according to the user transmitting gain degree of unbalance of M the antenna of possible Radio1 to the use habit of equipment, the transmitting gain degree of unbalance of the M of the Radio1 obtained according to this estimation antenna is disposed a described M antenna, and the transmitting gain degree of unbalance of the M of this Radio1 antenna is recorded in the configuration information of a described M antenna, so, just, can obtain according to the configuration information of a described M antenna transmitting gain degree of unbalance of a described M antenna.
Again further, in passing through network, when the transmitter antenna gain (dBi) of two antennas is uneven, in order to guarantee the performance of many antennas, the transmitting power of unbalanced two antennas of transmitting gain will be adjusted, so that this two antenna can reach the received power balance (also equating) of Correspondent Node, so, the adjusted value of the transmitting power of antenna just can be used as the degree of unbalance of the transmitting gain of this antenna, therefore the embodiment of the present invention can also record to determine according to the adjustment of the transmitting power of a described M antenna transmitting gain degree of unbalance of a described M antenna.
Concrete, from M the antenna of Radio1, an antenna of random selection is as reference antenna, and the transmitting gain degree of unbalance of this reference antenna is decided to be to 0dB (being equivalent to real number value 1), obtain the through-put power of each antenna, calculate the ratio of the through-put power of the through-put power of m transmitting antenna of Radio1 and reference antenna, obtain the transmitting gain degree of unbalance Tm of m the antenna of Radio1.This mode of antenna for base station is controlled by Correspondent Node situation for the transmitting power of Radio in each antenna of communication process and Radio1, a described M antenna refers in running order antenna (not considering to have cut out the not antenna of signal transmission).
It should be noted that, the embodiment of the present invention does not limit the execution sequence of step 201 and 202.
Afterwards, just can divide according to M the antenna of Radio1 antenna to be closed in M the antenna that the transmitting gain degree of unbalance of M the antenna of the isolation of N the antenna that is clipped to Radio2 and Radio1 determines Radio1, to close antenna described to be closed, reduce Radio1 with Radio2 when identical or successive bands are worked, to the interference of Radio2.The detailed description of this part referring to step 203 to step 205.
