Cell,
S23, for each uplink determined from system interference candidate cell, it is small from system interference candidate according to the uplink
Second measurement data of the terminal measurement in area and its adjacent area determines the uplink from system interference candidate cell in preset time grain
The second jamming power intensity in degree.
S24, each uplink is directed to from system interference candidate cell, if each uplink is corresponding from system interference candidate cell
Variation characteristic on each time granularity that preset duration includes of the first jamming power intensity and the second jamming power intensity
It is identical, it is determined that the uplink from system interference candidate cell be uplink from system interference cell.
When it is implemented, in order to accurately determine that uplink, can be for every from system interference cell, the embodiment of the present invention
One uplink analyzes its second jamming power Strength Changes characteristic in certain continuous duration from system interference candidate cell, compares
Whether it is identical as the first jamming power Strength Changes feature of base station measurement.Preferably, when it is implemented, can be to one day
(i.e. 24 hours) interior first jamming power intensity and the second jamming power intensity every 1 hour (time granularity i.e. in this example)
Variation characteristic is analyzed, for example, from the 1st time granularity to the 2nd time granularity, the first jamming power intensity and second
When jamming power intensity is reduced or is increased, referred to as the first jamming power intensity and the second jamming power Strength Changes characteristic
It is identical.
It describes in detail below in conjunction with specific embodiment of the attached drawing to step S23 and step S24.
When it is implemented, can determine that each uplink is small from system interference candidate in step S23 according to process shown in Fig. 3
Second jamming power intensity of the area in preset time granularity:
S231, for each uplink determined from system interference candidate cell, being determined according to preset engineering parameter should
Uplink is from the adjacent area of system interference candidate cell.
S232, the second measurement data that the uplink is measured from terminal in system interference candidate cell and its adjacent area is extracted.
S233, the second measurement data measured according to the uplink from terminal in the adjacent area of system interference candidate cell, determine
The interfered with terminal that the uplink is interfered from system interference candidate cell.
Specifically, the second measurement data of terminal measurement may include serving cell RSRP (Reference Signal Received Power)
The PRB that value, terminal transmission power headroom, serving cell Earfcn (carrier frequency point), PUSCH (Physical Uplink Shared Channel) are occupied
(Physical Resource Block) quantity, adjacent area PCI (Physical Cell Identifier) and corresponding adjacent area Earfcn and adjacent area RSRP.
It should be noted that there may be multiple adjacent areas for the serving cell of terminal, and therefore, the adjacent area number that terminal measurement obtains
According to as there are one-to-one relationship, i.e. terminal is needed for same neighbour between adjacent area PCI, adjacent area Earfcn and adjacent area RSRP
Area measures above three data respectively and is reported to serving BS, be uniformly reported to by serving BS above-mentioned server apparatus or
The existing network equipment of person.
Accordingly, interfered with terminal can be determined according to process shown in Fig. 4:
S2331, for the uplink from each terminal in the adjacent area of system interference candidate cell, if terminal measurement
Comprising the uplink from system interference candidate cell PCI in adjacent area PCI column, it is determined that the terminal is to wait to the uplink from system interference
Select the first candidate interfered with terminal that cell interferes.
That is in step S2331 from the uplink from the adjacent area of system interference candidate cell in terminal in selection meet following item
The adjacent area of part is as the first candidate interfered with terminal: including that the uplink is waited from system interference in the adjacent area PCI column of terminal measurement
Select cell PCI.
S2332, for every one first candidate interfered with terminal, according to the uplink from the Earfcn of system interference candidate cell with
And the serving cell Earfcn and adjacent area Earfcn of the first candidate interfered with terminal measurement, select serving cell Earfcn and adjacent area
Earfcn obtains the second candidate interference from the first equal candidate interfered with terminal of system interference candidate cell Earfcn with the uplink
Terminal.
In order to keep the selection result more acurrate, in step S2332, for every one first candidate interfered with terminal, according to this first
Serving cell EARFCH (carrier frequency point number) and its adjacent area EARFCH column in second measurement data of candidate interfered with terminal measurement
It determines the carrier frequency point that cell where the first candidate interfered with terminal uses and its carrier frequency point that adjacent area uses, and judges accordingly
The carrier frequency point that the cell and its adjacent area use and the uplink carrier frequency point used in the system interference candidate cell whether phase
Together, if identical, i.e., it may cause co-channel interference from system interference candidate cell to the uplink, that is to say, that step S2332
In, screening the uplink can may be done from system interference candidate cell generation co-channel interference from the first candidate interfered with terminal
Terminal is disturbed as the second candidate interfered with terminal.
S2333, determine that the second candidate interfered with terminal that the PRB quantity that PUSCH is occupied is not zero is to the uplink from system
The interfered with terminal that interference candidate cell interferes.
Finally, for every one second candidate interfered with terminal, according to the second measurement number of the second candidate interfered with terminal measurement
The PRB quantity that PUSCH in is occupied filters out the interfered with terminal that the PRB quantity of occupancy is not zero and is used as to the uplink from being
The interfered with terminal that system interference candidate cell interferes.
S234, determine in the preset time granularity all interfered with terminal to the uplink from system interference candidate cell
Jamming power aggregate-value is that the uplink is strong from second jamming power of the system interference candidate cell in the preset time granularity
Degree.
Specifically, can determine that the uplink exists from system interference candidate cell according to process shown in fig. 5 in step S234
The second jamming power intensity in the preset time granularity:
S2341, it is directed to each interfered with terminal, according to the adjacent area RSRP value of interfered with terminal measurement and is the uplink from system
The preconfigured reference signal transmission power of candidate cell is interfered, determines that the interfered with terminal is small to the uplink from system interference candidate
The link load in area.
For ease of description, link load of the note interfered with terminal to the uplink from system interference candidate cell is L, then L=
For the adjacent area RSRP value for reference signal transmission power-interfered with terminal measurement that the uplink is configured from system interference candidate cell.
S2342, according to the interfered with terminal measurement terminal transmission power headroom and be the preconfigured hair of the interfered with terminal
Power is penetrated, determines the actual emission power of the interfered with terminal.
Being assumed to be the preconfigured transmission power of the interfered with terminal is P1, and more than the terminal transmission that measures of the interfered with terminal
Amount is P1, then the actual emission power P=P1-P2 of the interfered with terminal.
S2343, according to the interfered with terminal to the uplink from the link load of system interference candidate cell and the interfered with terminal
Actual emission power, determine jamming power of the interfered with terminal to the uplink from system interference candidate cell.
In this example, then the interfered with terminal to the uplink from the jamming power of system interference candidate cell be (P-L).
S2344, determine in the preset time granularity all interfered with terminal to the uplink from system interference candidate cell
Jamming power aggregate-value be second jamming power intensity of the uplink from system interference candidate cell in the time granularity.

Interfered with terminal, the interfered with terminal and is counted to the uplink from the jamming power aggregate-value of system interference candidate cell in statistics 1 hour
Calculating all interfered with terminal, from the sum of the jamming power aggregate-value of system interference candidate cell to obtain second to uplink in 1 hour dry
Disturb power level.
It should be noted that need to compare in same time period in adjacent time granularity in the embodiment of the present invention first is dry
Power level and the second jamming power Strength Changes characteristic are disturbed, for example, with the preset duration that sets as 24 hours 1 day, setting
Time granularity is the first jamming power intensity then measured in per hour according to base station in 0. -24 point for 1 hour, Yi Jigen
Second jamming power intensity of the base station coverage cell between 0. -1 point, root are calculated in the measurement data of 0. -1 point according to terminal
First jamming power intensity of the base station coverage cell between 1. -2 point is calculated separately according to 1. -2 measurement data of base station,
And second jamming power of the base station coverage cell between 1. -2 point is calculated in the measurement data of 1. -2 point according to terminal
Intensity, and so on, it is strong successively to calculate 2. -3 points, the corresponding first jamming power intensity of 3. -4 points and the second jamming power
Degree, then compare the first jamming power intensity and the second jamming power Strength Changes spy in the adjacent time granularity in the same period
Property it is whether identical, if identical, it is determined that the uplink from system interference candidate cell be uplink from system interference cell, by
Uplink is from system interference.
Since the interference of LTE is broadly divided into from system interference and different system interference.The main original that different system interference generates
Because being since equipment radio frequency index is insufficient, system interval is insufficient from degree or the illegal of other systems uses, to eliminate different system
System interference, mainly by add tight RF index, increase system interval separation from or the means such as specification frequency usage.And it is dry from system
The uplink power transmitting disturbed mainly due to adjacent area terminal causes, to evade from system interference mainly by the hand of the network optimization
Section, such as adjustment Downtilt, deflection means.Therefore, it interferes or from system interference between differentiation LTE system for subsequent needle
The interference of property, which is evaded, handled etc., has important directive significance.
Uplink is each from the method for system interference, first basis in the determination wireless communication system provided in the embodiment of the present invention
The candidate cell that first jamming power intensity determination of a base station measurement may be interfered by uplink subsystem, later, for each
Candidate cell determines the candidate cell in preset time granularity according to the measurement data that the candidate cell and its adjacent area terminal measure
The second interior jamming power, if the first jamming power and second on each time granularity for including in certain continuous duration
Interference power variations characteristic is identical, then can determine that the candidate cell is uplink from system interference cell, it is thus achieved that upper
Row improves investigation efficiency of the uplink from system interference cell from the investigation of system interference cell, is based on this, subsequent to adopt
Interference elimination is carried out from system interference cell to uplink with targetedly interference elimination means, to guarantee the logical of wireless communication system
Believe quality.In addition, the method that the present invention implements to provide mainly passes through base station or the measurement data of terminal determines whether interference is certainly
