Description
Technical field
The present invention relates to a kind of directional antenna for mobile communication, more precisely, relate to a kind of adjustment System of being carried out portable antenna operating direction angle and the angle of declination automatically controlled by Surveillance center and the Internet.
Background technology
The Optimization Work of current mobile communications network is except the means such as adjustment, dilatation, rectification, newly-built station of sorts of systems parameter, to the directional antenna of community, mobile communication base station carry out operating direction angle and upper and lower dip angle parameter adjustment be the most frequently used method, the traffic demand of mobile subscriber can be absorbed to greatest extent, improve the coverage of single subdistrict and adjacent cell, improve the speech quality of network, meet the change demand of specific cell user capacity.
The adjustment of directional antenna parameter comprises: operating direction angle, mechanically angle of declination and electrical tilt angle etc.Current electrical tilt angle is built in antenna to realize with the phase place adjusting antenna oscillator, the angle of declination of built-in electrical tilt antenna maximum at present can only accomplish that the electricity of 0-10 degree is adjusted, most antenna does not have built-in electronic angle of declination, does not have electronics top rade yet.And the antenna cost of built-in electronic angle of declination is also relatively higher.Still the mechanically angle of declination of often adjustment antenna is needed in actual working environment.
Operating direction angle in current mobile communication is fixing, and adjustment needs attendant to arrive at a station to carry out manual operation.Adjustment machinery inclination angle up and down, the signal strength signal intensity of some weak signal overlay area can be changed fast, solve the complaint problem of the weak covering quality of network signal, can also optimize that adjacent area covers, covering crossed by antenna and the excessive or too small problem of soft handover area, optimizing pilot pollutes cause call drop, capacity decline, degradation situation under speech quality.By adjusting the mechanically angle of declination of antenna, antenna beam directly can point to overlay area, avoids interference other communities.Thus the lifting of power system capacity all can be brought to macrocellular or micro-cellular environment.The effect that antenna has a down dip: 1) antenna has a down dip cell coverage area can be made to diminish; 2) antenna downtilt makes the gain of antenna on interference radiating way reduce, and is equivalent to antenna decoupling increase on the vertical plane; 3) strengthen the signal strength signal intensity in this area of coverage after antenna downtilt, both improved the field intensity of community, turn increase the ability of Cochannel interference; 4) antenna updip can cover skyscraper region again, reaches best coverage effect and absorbs the effect that traffic increases operator's income.
Therefore adjusting operating direction angle, the mechanically angle of declination of antenna, when not producing severe jamming, more preferably coverage can be obtained.In TD-SCDMA network, due to the self-interference characteristic of system, the network optimization only can not be conceived to the community isolated, must carry out in units of cell cluster, if that is the covering of certain community and performance unsatisfactory when, coverage can be adjusted by the operating direction angle and upper angle of declination adjusting this antenna in cell, after adjustment completes, need the performance of each neighbor cell in the same cell cluster of timely testing evaluation, and corresponding adjustment may be made again by produced problem to these communities, this often causes antenna parameter adjustment to become the process of a circulation.Show according to industry experience, a cell cluster needs to do 3 ~ 7 adjustment before reaching desired operation, and in once large optimization, have the antenna in cell of 60% all to need to carry out operating direction angle and mechanically angle of declination adjustment.
On the other hand, will to the operating direction angle of directional antenna and the adjustment of mechanical tilt angle, technical staff just must be allowed to climb such as steel tower, communication pole, the contour empty position of roof, after technical staff uses instrument to unscrew the set bolt of astronomical cycle securing member, again with staff rotary antenna to the operating direction angle needing to adjust or mechanical tilt angle, the nut of tightening fastener parts again after having adjusted.It should be noted that aerial mechanical deflection and mechanically angle of declination adjustment time, must tighten the screws and worm screw, avoid making operating direction angle or mechanical tilt angle that displacement change occurs by environmental impacts such as strong wind.
Optimize the real data that personnel often wish to obtain accurate aerial mechanical deflection and mechanically angle of declination, and the numerical value of the directional antenna operating direction angle of current known mobile communication system and mechanically angle of declination is substantially all the numerical value that an application condition is large simultaneously.Here mainly because current metering system is use compass to carry out manual measurement mostly, because compass utilizes magnetic field of the earth to determine deflection, a high frequency magnetic field can be there is in the place of installing portable antenna, therefore can produce interference, allow survey crew cannot direction of measurement angle number accurately.Mechanically angle of declination is then use angle of declination instrument to measure at the antenna back side, different survey crew measurements there will be measure error, and manually remove also can cause when rotary antenna operating direction angle and mechanical tilt angle alignment error, this just makes the parameter of current mobile communication directional antenna operating direction angle and mechanically angle of declination there is larger error, and this error range is everlasting between 5-20 degree.
This error is especially when two, same sector antenna horizontal angle is inconsistent, there will be more serious network quality covering problem, too high and the call drop of the handover failure rate of adjacent base station minizone can be caused, the difficulties that these needs especially in network optimization solve.The mode of this artificial adjustment machinery deflection and mechanically angle of declination is used till today from mobile communication is born always, due to the existence of this alignment error, brings very adverse influence to the network planning in the future and the network optimization.If operating direction angle and the mechanically adjustment of angle of declination and data acquisition therefore accurately can be implemented rapidly, the network quality improving mobile communication is had very important significance.The artificial adjustment mode of current mobile communication directional antenna operating direction angle and mechanically angle of declination can not meet the needs of the network optimization day by day promoted.
