For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.All relate to the base station and issue the control command that the order of electrical modulation tower amplification all is based on existing standard agreement (including but not limited to the AISG agreement) in the present invention program, all electrical modulation tower amplifications itself also are based on existing standard agreement (including but not limited to the AISG agreement) and realize, himself can realize the external control behavior, and returns execution result.In the installation process of the base station of reality, its electrical modulation tower amplification part normally is fixedly mounted on the eminence of outdoor architecture thing.Transfer in the survey in base station subsequently, adjust the up coverage of aerial signal by the gain of adjusting electrical modulation tower amplification.
In service in base station subsequently, owing to some reasons, may cause the actual gain of electrical modulation tower amplification and the original gain of expecting inconsistent, it is incorrect promptly to gain.These reasons may be: outside irresistible power effect (such as typhoon etc.), or because the defective of electrical modulation tower amplification internal system, again or owing to artificially electrical modulation tower amplification installation factor has been carried out adjusting (such as the people is for having reinstalled electrical modulation tower amplification).Gaining incorrectly then may cause the inconsistent of the up coverage effect of aerial signal and original expection, and then may cause the local business of wireless access network normally not move.Under these circumstances, just need adjust, to be consistent with desired value to the gain of electrical modulation tower amplification.
The embodiment of the invention one relates to the method for adjusting electrical modulation tower amplification gain.In the present embodiment, by the treatment mechanism of automatic inquiry and adjustment, guarantee that the gain of electrical modulation tower amplification in the running of base station is consistent with user configured expection gain.Specifically as shown in Figure 1:
Step 100-110, during timer expiry, the base station sends the query requests of current operation gain to electrical modulation tower amplification;
The base station by with the information interaction of electrical modulation tower amplification, inquire about the gain of described electrical modulation tower amplification.In this step, the cycle of base station transmission inquiry request message can be set according to actual needs, such as, one hour or other times of day.The base station can be provided with timer, the gain of inquiry electrical modulation tower amplification when timer expiry, and restart this timer.With the cycle be one hour be example, base station initiated one hour periodicity timer, in the time of timer expiry, the base station initiatively sends the request message of the current operation gain of inquiry electrical modulation tower amplification to the electrical modulation tower amplification control section;
In this step, query requests can be used the inquiry TMA gain interface that defines in the AISG agreement.
Receive the inquiry request message of base station when electrical modulation tower amplification after, according to this request message, the gain A of the current operation of electrical modulation tower amplification control section inquiry electrical modulation tower amplification self, and send it to the base station;
Concrete, the gain of the current operation of electrical modulation tower amplification self can be the actual gain of the current data feedback channel of electrical modulation tower amplification, can obtain in the following manner: electrical modulation tower amplification control section inquiry tower is put the row of channels input power, and tower is put the row of channels power output, put the difference of row of channels input power and data feedback channel power output by calculating tower, obtain the actual gain that tower is put current data feedback channel.
In this step, after the base station receives the current operation gain A of electrical modulation tower amplification, with this gain be kept at expection electrical modulation tower amplification gain value B in the base station configuration data storehouse, original users configuration and compare, if both unanimities, the gain that this electrical modulation tower amplification then is described is normal, need not to adjust, finish this processing, return and continue to judge whether timer is overtime; If both are inconsistent, then enter step 140.
Concrete process relatively can be: base station control unit is obtained the electricity of this code T MA and is transferred yield value B according to concrete TMA numbering from the base station configuration data storehouse.
The situation of both unanimities might not be absolute equating, in the actual conditions, allows certain error range, if in error range, just thinks that both are consistent, and does not adjust.Tower is put kinds such as can being divided into three workers, duplex and Dan Gong.Put with San Gongta and to be example, suppose that the expection Configuration Values B of gain is 12dB, the error range of permission is 12 ± 0.5dB, so, if gain A is 12.2dB, belongs in the scope that error allows, and just can think that both are consistent.
And inconsistent situation, may be greater than, also may be less than.Though be greater than or less than, all can bring certain negative consequence.Such as, if A is less than B: can make the up coverage effect variation in base station, it is up to cause downstream signal to be better than, and it is unsuccessful to make the user insert; If A is greater than B: the signal to the base station input can strengthen, and is corresponding, can increase the weight of the uplink load of base station, and this can reduce the up disposal ability in base station to a certain extent.So, under inconsistent situation, need adjust the gain of electrical modulation tower amplification.
In this step, base station control unit is by the AISG link, send the message of adjusting electrical modulation tower amplification gain to the electrical modulation tower amplification control section, carry the expection Configuration Values in this message, specify current operation gain to be adjusted to gain expection Configuration Values B electrical modulation tower amplification by this message.
In the step 150, electrical modulation tower amplification is adjusted to expection Configuration Values B with current operation gain after receiving and adjusting gain adjustment message;
In this step, the electrical modulation tower amplification control section is after receiving this message, from message, obtain expection Configuration Values B, adjust the attenuation of its inner data feedback channel, and measure the up input power that tower puts and the difference of up power output in real time, stop to adjust tower and put inner decay when difference is identical with expection Configuration Values B, this moment, tower was put the row gain gain B of expection just.
Further, step 160, after electrical modulation tower amplification was adjusted to the gain of current operation the expection Configuration Values, electrical modulation tower amplification can return to the base station and adjust the successful response message of gain.
Base station system thinks that this moment, electrical modulation tower amplification gain expected that with gain Configuration Values is consistent after receiving the successful response message of adjustment gain, also promptly guaranteed up coverage effect of aerial signal and quality of service at this moment, end process.
The method that the embodiment of the invention provides, by periodic inquiry electrical modulation tower amplification gain, and and the yield value of expection configuration compare, when both are inconsistent, electrical modulation tower amplification gain is adjusted to the yield value of expection configuration.Thus, solved the inconsistent problem of gain of the gain and the expection configuration of the base station electrical modulation tower amplification actual motions that may occur more in service, make the actual motion gain of electrical modulation tower amplification regularly to adjust, improve the gain stability of electrical modulation tower amplification, and then guaranteed certain hour scope internal antenna signal uplink coverage effect, make can normally the moving of wireless access network service.
