Description
Technical field
The present invention relates to fields of communication technology, and in particular to the localization method and device of a kind of external disturbance.
Background technology
In the wireless network, the common interference in base station is divided into internal system interference and exterior interferes, cadre in system
Disturb typically base station planning, parameter setting are unreasonable, project installation it is lack of standardization caused by, exterior interference be then that some coexist
Or the alien frequencies system of co-sited is mutually interfered, repeater, industrial electromechanical equipment, signal lamp, broadcasting station equipment, caused by shielding device etc..
The transmission power of base station is generally far larger than external disturbance source power, so external disturbance will not generally cause to do to downlink
It disturbs, but the normal work of the uplink of base station can be influenced, therefore localized external interference source becomes the network optimization and in O＆M one
A critically important problem.
The method that external disturbance generally uses cross bearing is investigated in engineering at present.As shown in Figure 1, it is deposited in network is determined
Under the premise of external disturbance, choose multiple positions and jamming power measurement is carried out by spectrum analyzer and directional aerial, every
A test position marks the most strong direction of jamming power, finally selects the intersection in the most strong direction of multiple test position jamming powers
Placement of the point for doubtful external interference source, and then the positioning closer to distance is carried out, gradually reduce the scope.It is adopted in engineering at present
The method of external disturbance cross bearing is needed using professional equipments such as spectrum analyzer, directional aerials, and needs profession
Technical staff is operated, and interference unit investigation work takes, effort.In addition, in practical troubleshooting procedure, it is difficult to accurately determine every
A most strong direction of interference for measuring position, inevitably introduces uncontrollable factor, substantially increases the uncertainty of investigation result.
In addition, external disturbance can generally use the frequency identical with mobile communication system, so when being interfered using spectrum analyzer
During measurement, external interference signals may be submerged under base stations in mobile communication system signal, cause positioning work can not be normal
Carry out.
In a kind of localization method of existing external disturbance, the corresponding all measurement reports of each grid region are utilized
Grid interference matrix is established in the interference that enters of cell where (Measurement Report, MR) and grid region, is done according to grid
It disturbs matrix and judges that whether entering for each grid is interfered less than internal interference, if entering interference is less than internal interference and grid matter difference MR
Ratio is higher than threshold value, then judges that there are external disturbances for grid.The foundation of the interference matrix is accurate based on lump jamming power
(being into interference) is calculated, and the uncertainty of wireless channel can introduce uncontrollable calculating error, so as to make the accurate of this method
Degree is had a greatly reduced quality.In addition, this method is mainly directed towards gsm system, it is not the LTE system being suitable for using identical networking technology,
The matter difference MR of the serious grid of overlapping covering is higher than regular meeting in LTE system, therefore can not be by setting grid endoplasm poor
MR ratios thresholding judges whether the grid has external disturbance.
In the localization method of another existing external disturbance, it is first determined whether there are uplink outer interference, if depositing
The propagation loss for being respectively disturbed cell then influenced according to being transmitted to interference signal by same interference source, be respectively disturbed it is small
The reception in area is disturbed the horizontal direction angle of cell with internal power and respectively, calculates the location information of the same interference source.
The effect that external disturbance positions in this method depends on the accurate calculating of propagation loss, but the uncertain meeting of wireless channel
Uncontrollable calculating error is introduced, so as to which the accuracy for making this method is had a greatly reduced quality.
