Embodiment

It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, limit is not used to The fixed present invention.

The primary solutions of the embodiment of the present invention are：Monitor the up-link capacity ginseng of multiple neighbor cell base stations Number；According to the up-link capacity parameter, the uplink downlink for obtaining the multiple neighbor cell base station is uneven Weighing apparatus degree；If the uplink downlink degree of unbalancedness meets default heavy with condition, the multiple phase is controlled The cell individual character skew CIO parameters of user equipment weight matched adjacent zone in adjacent cell.

Because prior art is when the ascending load of neighbor cell base station has differences, neighbor cell can be caused Uplink downlink it is uneven, not only disturb the signal of neighbor cell base station, and have impact on user and set Standby service experience.

The present invention provides a solution, the CIO parameters of dynamic adjustment cell, uneven region User be converted to soft handover area user so that uneven area user enjoy macro-diversity Merging zone method come it is upper Row income.

Reference picture 1, CIO methods of adjustment first embodiment of the present invention provides a kind of CIO methods of adjustment, institute Stating CIO methods of adjustment includes：

Step S10, the multiple neighbor cell base stations of monitoring up-link capacity parameter.

The embodiment of the present invention is by monitoring user equipment dynamic in the running status of neighbor cell, control cell The CIO parameters of neighbor cell are adjusted, the uneven area of uplink downlink is converted to soft handover area, drops significantly It is low or avoid in macro network doing because inter-cell uplink load has inter-cell uplink caused by larger difference Disturb problem, the uplink service experience of lifting macrocell.

The embodiment of the present invention is supervised by RNC (Radio Network Controller, radio network controller) Cell running status is controlled, control user equipment adjusts the CIO parameters of neighbor cell, carries out link management. It is, of course, also possible to carry out the management of cell base station by other devices, can flexibly it set according to actual needs.

Specifically, as a kind of embodiment, first, RNC monitors multiple neighbor cell base stations in real time Up-link capacity parameter, obtains the running status of current neighbor cell.

The up-link capacity parameter that RNC monitorings are obtained includes every up-link capacity that each cell base station is currently run Parameter, such as ascending load L (Load), noise incremental quantity RoT (Rise over Thermal noise).

In the present embodiment, ascending load characterizes the uplink load situation of each cell base station；Noise Make an uproar lifting situation at the up bottom that increment characterizes each cell base station.

Step S20, according to the up-link capacity parameter, obtain the up-downgoing of the multiple neighbor cell base station Link degree of unbalancedness.

After the up-link capacity parameter of each cell base station is obtained, RNC is adjacent according to up-link capacity parameter acquiring The uplink downlink degree of unbalancedness of cell base station.

Specifically, the uplink downlink degree of unbalancedness for taking neighbor cell is DU, according to the noise of neighbor cell Increment or ascending load calculate the degree of unbalancedness of current neighbor cell link.

It is illustrated with currently having 2 neighbor cell base stations.

Current base station A signal is taken to cover A cells, the user equipment for A cells provides service；Take A The adjacent cell of cell is B cells, and B cells provide service by base station B.

Then RNC real-time monitoring base station A and base station B link running status, obtains base station A and base station B up-link capacity parameter, obtained up-link capacity parameter includes noise incremental quantity RoT and ascending load L etc..

After up-link capacity parameter is obtained, as a kind of embodiment, up-downgoing is calculated according to noise incremental quantity Link degree of unbalancedness.

The noise incremental quantity for taking A cells is RoTa, and the noise incremental quantity of B cells is RoTb, then DU is RoTa With RoTb function, namely DU=(RoTa, RoTb).

Uplink downlink degree of unbalancedness and RoTa, RoTb functional relation can flexibly be set.

As another embodiment, uplink downlink degree of unbalancedness is calculated according to ascending load.

The load for taking A cells is La, and the load of B cells is Lb, then DU is La and Lb function, Namely DU=(La, Lb).

Uplink downlink degree of unbalancedness and La, Lb functional relation can flexibly be set.

Thus, the uplink downlink degree of unbalancedness of neighbor cell base station is obtained.Obtained degree of unbalancedness is characterized The uneven degree of the uplink downlink of current neighbor cell base station.

If step S30, the uplink downlink degree of unbalancedness meet default heavy with condition, control is described The cell individual character skew CIO parameters of user equipment weight matched adjacent zone in multiple neighbor cells.

After uplink downlink degree of unbalancedness is obtained, if uplink downlink degree of unbalancedness meets default heavy match somebody with somebody The cell individual character skew CIO parameters of condition, then user's weight matched adjacent zone in the multiple neighbor cells of RNC controls.

Specifically, as a kind of embodiment, RNC, which is provided with advance, matches somebody with somebody condition, current for judging again Whether the CIO parameter reconfiguration of progress cell base station is needed.What is be pre-configured with can be again default with condition Threshold value, the parameter such as uneven threshold value, balance threshold value.

When uplink downlink degree of unbalancedness reaches default uneven threshold value, then uplink downlink is judged Degree of unbalancedness meets default heavy with condition, and current adjacent cell uplink downlink is uneven more serious, The up-link of base station is heavily disturbed, influences the experience of user, now, and RNC needs to carry out CIO Parameter reconfiguration.

Then, RNC obtains serving cell belonging to current UE (User Equipment, user equipment) Neighbor cell, namely UE adjacent area, reconfigure UE adjacent area CIO parameters.It is each that RNC matches somebody with somebody again Adjacent area CIO parameters can be the parameter value being pre-configured with, and can also be what is configured according to current degree of unbalancedness, It can also be according to 1A event measurement report parameter configurations, can also be other configurations mode, can basis It is actually needed flexible setting.It should be noted that in the embodiment of the present invention, UE refers to user equipment.

Then, RNC sends in control message (Message control), control message to UE and carried The CIO configuration parameters of each homogeneous frequency adjacent area of the affiliated serving cell of current UE, namely UE each adjacent area CIO configuration parameters.

UE is received after the control message of RNC transmissions, obtains each adjacent area CIO configurations that control message is carried Parameter.When UE is being moved to neighbor cell, if detecting the descending primary common pilot of neighbor cell, After the pilot channel mass parameter of adjacent area is obtained, it is adjusted according to the CIO configuration parameters of current neighbor and led Frequency channel quality parameter, the pilot channel mass parameter after being offset.

Then, whether the pilot channel mass parameter that UE is assessed after skew meets 1A event measurement report bars Part.If the pilot channel mass parameter after skew meets 1A event measurement report conditions, UE is to RNC Measurement report is sent, soft handover is carried out, the in advance or delayed of UE soft handovers is realized.

If for example, UE current service cell ascending load is more than adjacent area ascending load, RNC configurations The CIO parameters of the adjacent area are 4dB, then UE can in advance occur when being moved to adjacent area in uneven area Soft handover, reduces and the upward signal of cell base station is disturbed；If UE current service cell ascending load is small In adjacent area ascending load, then the CIO parameters that RNC configures the adjacent area are -4dB, then UE is moved to adjacent area When dynamic, it can reduce and the upward signal of cell base station is disturbed with delayed generation soft handover.

Subsequently, RNC continues the up-link capacity parameter according to default frequency monitoring neighbor cell base station, obtains Take the uplink downlink degree of unbalancedness of neighbor cell base station.If RNC is monitored above and below neighbor cell base station Line link degree of unbalancedness changes, less than the balance threshold value being pre-configured with, and meets default heavy with bar Part, then RNC reconfigure UE adjacent area CIO parameters, obtain CIO configuration parameters.

Then, RNC sends control message to UE, and control UE matches somebody with somebody again according to new CIO configuration parameters The CIO parameters of adjacent area, it is to avoid the UE under neighbor cell base station uplink downlink poised state is to adjacent The upward signal interference of cell.

Hereafter, RNC continues the up-link capacity parameter according to default frequency monitoring neighbor cell base station, obtains The uplink downlink degree of unbalancedness of neighbor cell base station is taken, is met in uplink downlink degree of unbalancedness and matches somebody with somebody bar again The adjacent area CIO parameter reconfigurations of UE in cell are controlled when part.

Hereby it is achieved that the CIO parameters of dynamic control UE weights matched adjacent zone, are reduced to the upper of cell base station Row signal is disturbed.

As another embodiment, after uplink downlink degree of unbalancedness is obtained, may be used also again with module 30 To control UE weight matched adjacent zone CIO parameters, in combination with the tune of cell base station Primary Common Pilot Channel power It is whole, the interference that reduction neighbor cell base station uplink downlink imbalance is caused.

In the present embodiment, the up-link capacity parameter of multiple neighbor cell base stations is monitored；Then, according to upper Row capacity parameter, obtains the uplink downlink degree of unbalancedness of multiple neighbor cell base stations；If uplink downlink Degree of unbalancedness meets the default heavy user equipment weight matched adjacent zone matched somebody with somebody condition, then control in multiple neighbor cells CIO parameters.Due to the difference of neighbor cell base station ascending load, it can cause to exist between neighbor cell Uplink downlink imbalance region, and the present embodiment by monitoring the up-link capacity of neighbor cell base station in real time Parameter, obtains the uplink downlink degree of unbalancedness of neighbor cell, and the uplink downlink in neighbor cell is uneven Weighing apparatus degree reaches default heavy when matching somebody with somebody condition, RNC control UE, namely user equipment, the CIO of weight matched adjacent zone Parameter, so that UE is in moving process, soft handover area can be adjusted as needed, adjacent base station is reduced The upward signal interference being subject to, while also reducing the influence that user equipment in cell is subject to.Adjacent small When the ascending load of area base station has differences, the embodiment of the present invention effectively reduces the letter that cell base station is subject to Number interference, reduces influence to user service in cell, improves Consumer's Experience.

Further, reference picture 2, CIO methods of adjustment second embodiment of the present invention provides a kind of CIO and adjusted Adjusting method, based on the embodiment shown in above-mentioned Fig. 1, the heavy condition of matching somebody with somebody includes uneven condition, described Step S30 includes：

If step S31, the uplink downlink degree of unbalancedness meet default uneven condition, according to institute The event detection parameter stated uplink downlink degree of unbalancedness and/or be pre-configured with, obtains the user equipment Adjacent area CIO configuration parameters.

After the uplink downlink degree of unbalancedness of neighbor cell base station is obtained, if uplink downlink degree of unbalancedness Default uneven condition is met, namely current neighbor cell is the uneven processing state of uplink downlink, Then RNC obtains UE's according to uplink downlink degree of unbalancedness and/or the event detection parameter being pre-configured with Adjacent area CIO configuration parameters.

Specifically, as a kind of embodiment, serving cells of the RNC according to belonging to UE is current is obtained Neighbour cell as UE adjacent area.

The adjacent area CIO configuration parameters for taking UE are CIOs, and the serving cell belonging to UE is upper with its adjacent area Downlink degree of unbalancedness is DUs, and the event detection parameter being pre-configured with is 1A event monitoring parameters R1A.

Then CIOs is DUs and R1A function, namely CIOs=(DUs, R1A).

If the serving cell ascending load belonging to UE is current is loaded more than adjacent area, RNC sets the adjacent area CIO parameters be on the occasion of being easy to UE when move to the adjacent area, occur soft handover in advance, reduce pair The upward signal interference of cell base station.Then RNC can set the CIOs=︱ DUs ︱ of the adjacent area, certainly, As ︱ DUs ︱>| R1A |, CIOs=︱ DUs ︱-︱ R1A ︱ can also be set, DUs is may be arranged as With R1A other functions, can flexibly it set according to actual needs.

If the serving cell ascending load belonging to UE is current is loaded less than adjacent area, RNC sets the adjacent area CIO parameters be negative value, be easy to UE when move to the adjacent area, delayed generation soft handover, reduce pair The upward signal interference of cell base station.Then RNC can set the CIOs=- ︱ R1A ︱ of the adjacent area, may be used also To be set to DUs and R1A other functions, can flexibly it set according to actual needs.

Thus, UE adjacent area CIO configuration parameters have been obtained.

Serving cells of the RNC according to belonging to each UE, weighs the CIO configuration parameters of matched adjacent zone respectively, realizes For the personalized heavy matched adjacent zone CIO configuration parameters of UE communications status.

Step S32, to the user equipment control message is sent, the control message carries the user The adjacent area CIO configuration parameters of equipment.

After UE adjacent area CIO configuration parameters are obtained, RNC sends control message to UE, and control disappears UE new Intra Freq Cell List (new co-frequency neighbor cell list) are carried in breath.

Each homogeneous frequency adjacent area of the affiliated serving cell of current UE is listed in new Intra Freq Cell List Information, namely UE each neighboring BS information.

Include the CIO configuration parameters of each adjacent area of RNC configurations in each neighboring BS information.

Step S33, the control user equipment are used with described again according to the adjacent area CIO configuration parameters The adjacent area CIO parameters of family equipment.

RNC is sent after control message to UE, and control user equipment is according to adjacent area CIO configuration parameters, weight With its adjacent area CIO parameters.

Specifically, as a kind of embodiment, UE is received after control message, according to new Intra Freq Cell List obtains the CIO configuration parameters of its each adjacent area, and matches somebody with somebody it again according to the CIO configuration parameters of its each adjacent area Corresponding each adjacent area CIO parameters.

If UE detects the descending pilot frequency of adjacent area, disturbed according to the intensity of the neighbor received signal and adjacent area Level, obtains the pilot channel mass parameter of the adjacent area.

Then, RNC obtains the neighbor pilot channel quality and adjacent area CIO configuration parameter sums, obtains Data be used as the adjacent area skew after pilot channel mass parameter.

Then, the pilot channel mass parameter after UE is offset according to the adjacent area, judges the small of the current adjacent area Whether area's descending pilot frequency triggers 1A events.

If the pilot channel mass parameter after the skew of adjacent area meets 1A event measurement report conditions, to RNC Report the measurement report of the adjacent area.If the pilot channel mass parameter after the skew of adjacent area is unsatisfactory for the survey of 1A events Amount reporting conditions judgement does not trigger 1A events, and the measurement report of the adjacent area is not reported to RNC.

RNC is received after UE measurement report, and control UE carries out soft handover.Cut hereby it is achieved that UE is soft That changes is in advance or delayed, so as to reduce the uneven caused upward signal interference of neighbor cell uplink downlink.

Currently to there are 2 neighbor cell base stations to be illustrated.

It is B cells to take the adjacent cell of A cells, and A cells provide service by base station A, and B cells are by base The B that stands provides service.In the up-link capacity parameter of acquisition, the noise incremental quantity of A cells is RoTa, B cells Noise incremental quantity be RoTb.Base station A ascending load is La, and base station B ascending load is Lb.

In the present embodiment, uplink downlink degree of unbalancedness DU=RoTa-RoTb, or DU=1/ (1-La)- 1/(1-Lb)。

Reference picture 10, when uplink downlink degree of unbalancedness is not up to default uneven threshold value, then when Uplink downlink poised state, namely upper row bound and descending pilot frequency are between preceding A cells and B cells Border overlay, coverage is identical.

When UE is into B cell moving process in A cells, into covering jointly for base station A and base station B During lid scope, base station B downstream signal is able to detect that.UE obtains currently detected base station B and led Frequency channel quality parameter.

When current pilot channel mass parameter meets 1A event measurement report conditions, UE is on RNC Report current measurement report.RNC controls UE to carry out soft handover according to measurement report.

Reference picture 11, if base station A ascending load is more than base station B ascending load, uplink downlink is not The degree of balance reaches default uneven threshold value, namely more than or equal to default uneven threshold value.This When, DU>0.

Then due to cell breath, base station A up coverage reduces, base station B up coverage Expand.But, base station A and base station B descending pilot frequency boundary position is constant.

Base station A can then be caused and in the B superimposed coverage areas of base station, the upper row bound after change is led with descending Scope between frequency border is uneven area, the UE in uneven area in order to obtain base station A service, Increase uplink signal transmission power.Enhanced UE upward signals are dry for seriously up for base station B Disturb signal.

Now, RNC judges that current uplink downlink degree of unbalancedness meets default heavy with condition, then distinguishes UE into each cell sends control message, and control UE reconfigures the CIO parameters of adjacent area.

For the UE in A cells, because the adjacent area of UE in A cells is B cells, then RNC is controlled UE in A cells matches somebody with somebody the CIO parameters of B cells again；For the UE in B cells, due to B cells Middle UE adjacent area is A cells, then the CIO that RNC controls the UE in B cells to match somebody with somebody A cells again joins Number.

It is used as a kind of embodiment, reference picture 12.

The CIO configuration parameters with B cells are CIOb=DU-R1A, wherein DU to RNC again>R1A.Then, UEs of the RNC into A cells sends control message, and control message carries the CIO configuration ginsengs of B cells Number CIOb.

UE in A cells is obtained after RNC control message, matches somebody with somebody B cells again according to control message CIO parameters are DU-R1A.Hereafter, the UE in A cells to B cells move when, it is necessary to will detect Base station B pilot channels mass parameter plus CIOb offset after pilot channel mass parameter.Then, Judge whether the pilot channel mass parameter after skew meets 1A event measurement report conditions again.

When UE row bounds in arrival in A cells, the pilot channel mass parameter after skew meets 1A During event measurement report condition, trigger 1A events, in A cells UE to RNC reporting measurement reports, Allow in A cells UE to advance to up boundary and occur soft handover, realize former uneven area Soft handover area is converted to, the upward signal interference that UE is caused to base station B in former uneven area is reduced.

Meanwhile, RNC can the CIO configuration parameters with A cells be again CIOa=-R1A.Then, RNC UE into B cells sends control message, and control message carries the CIO configuration parameters CIOa of A cells.

UE in B cells is obtained after RNC control message, matches somebody with somebody A cells again according to control message CIO parameters are-R1A.Hereafter, the UE in B cells to A cells move when, it is necessary to will detect Base station A pilot channels mass parameter adds the pilot channel mass parameter after CIOa is offset.Then, Judge whether the pilot channel mass parameter after skew meets 1A event measurement report conditions again.

When UE reaches descending boundary in B cells, the pilot channel mass parameter after skew meets 1A Event measurement report condition, triggering UE in 1A events, B cells, to RNC reporting measurement reports, makes UE can be with delayed to just generation soft handover at descending boundary in B cells, it is to avoid UE in B cells The upward signal interference that soft handover is caused to base station B occurs to early, while alleviating the up negative of base station A Load with load.

It is used as another embodiment, reference picture 13.

The CIO configuration parameters with B cells are CIOb=DU to RNC again.Then, RNC is into A cells UE send control message, control message carries the CIO configuration parameters CIOb of B cells.

UE in A cells is obtained after RNC control message, matches somebody with somebody B cells again according to control message CIO parameters are DU.Hereafter, the UE in A cells to B cells move when, it is necessary to by the base detected B pilot channels mass parameter of standing adds the pilot channel mass parameter after CIOb is offset.Then, then Judge whether the pilot channel mass parameter after skew meets 1A event measurement report conditions.

When UE row bounds in arrival in A cells, the pilot channel mass parameter after skew meets 1A Event measurement report condition, triggering UE in 1A events, A cells, to RNC reporting measurement reports, makes Soft handover occurs for the region that UE can be advanceed to beyond row bound in A cells, not only realize by Former imbalance area is converted to soft handover area, and expands soft handover area, not only reduces former imbalance The upward signal interference that UE is caused to base station B in area, also reduces A cell portion user equipmenies to base The upward signal interference that the B that stands is caused.

Similarly, if base station B ascending load is more than base station A ascending load, uplink downlink is uneven Degree reaches default uneven threshold value, namely more than or equal to default uneven threshold value.Now, DU<0。

The CIO configuration parameters with A cells are CIOa=-DU-RIA or CIOa=-DU to RNC again.Then, UEs of the RNC into B cells sends control message, and control message carries the CIO configuration ginsengs of A cells Number CIOa.

UE in B cells is obtained after RNC control message, matches somebody with somebody A cells again according to control message CIO parameters.Hereafter, the UE in B cells to A cells move when, it is necessary to by the base station A detected Pilot channel mass parameter adds the pilot channel mass parameter after CIOa is offset.Then, then judge Whether the pilot channel mass parameter after skew meets 1A event measurement report conditions.

If CIOa=-DU-RIA, when row bound in UE arrival in B cells, the pilot tone letter after skew Road mass parameter meets 1A event measurement report conditions, triggers 1A events；If CIOa=-DU, when When UE does not reach row bound in B cells, namely beyond upper row bound, the pilot channel quality after skew Parameter meets 1A event measurement report conditions, triggers 1A events.

Trigger after 1A events, UE is to RNC reporting measurement reports in B cells so that UE in B cells Region beyond up boundary or upper row bound can be advanceed to and occur soft handover, not only realize by Former imbalance area is converted to soft handover area, and expands soft handover area, not only reduces former imbalance The upward signal interference that UE is caused to base station A in area, also reduces B cell portion user equipmenies to base The upward signal interference that the A that stands is caused.

Meanwhile, RNC can the CIO configuration parameters with B cells be again CIOb=-R1A.Then, RNC UE into A cells sends control message, and control message carries the CIO configuration parameters CIOb of B cells.

UE in A cells is obtained after RNC control message, matches somebody with somebody B cells again according to control message CIO parameters are-R1A.Hereafter, the UE in A cells to B cells move when, it is necessary to will detect Base station B pilot channels mass parameter adds the pilot channel mass parameter after CIOb is offset.Then, Judge whether the pilot channel mass parameter after skew meets 1A event measurement report conditions again.

When UE reaches descending boundary in A cells, the pilot channel mass parameter after skew meets 1A Event measurement report condition, triggering UE in 1A events, A cells, to RNC reporting measurement reports, makes UE can be with delayed to just generation soft handover at descending boundary in A cells, it is to avoid UE in A cells The upward signal interference that soft handover is caused to base station A occurs to early, while alleviating the up negative of base station B Load with load.

Hereby it is achieved that each UE weights matched adjacent zone CIO parameters in RNC controls neighbor cell.

In the present embodiment, after the uplink downlink degree of unbalancedness for obtaining neighbor cell base station, if up-downgoing Link degree of unbalancedness meets default uneven condition, matches somebody with somebody according to uplink downlink degree of unbalancedness and/or in advance The event detection parameter put, obtains the adjacent area CIO configuration parameters of user equipment；Then, to user equipment Control message is sent, control message carries the adjacent area CIO configuration parameters of user equipment；Control user sets It is standby according to adjacent area CIO configuration parameters, adjacent area CIO parameters with user equipment again.The present embodiment is default not Equilibrium condition, when adjacent cell base station uplink downlink degree of unbalancedness meets uneven condition, according to Uplink downlink degree of unbalancedness and/or the time detecting parameter configuration adjacent area CIO configuration parameters being pre-configured with, By sending control message to user equipment, each user equipment is controlled to be matched somebody with somebody again according to CIO configuration parameters respectively Adjacent area CIO parameters, realize the actual communication state for each user equipment, personalized configuring adjacent cell CIO parameters, optimize the CIO configuration parameters of each user equipment adjacent area so that user equipment shift to an earlier date or Delayed generation soft handover, reduces and the upward signal of cell base station is disturbed, improve Consumer's Experience.

Further, reference picture 3, CIO methods of adjustment 3rd embodiment of the present invention provides a kind of CIO and adjusted Adjusting method, based on the embodiment shown in above-mentioned Fig. 1, the heavy condition of matching somebody with somebody includes equilibrium condition, the step Rapid S30 includes：

If step S34, the uplink downlink degree of unbalancedness meet default equilibrium condition, control is described User equipment is according to default balance parameters value weight matched adjacent zone CIO parameters.

After the uplink downlink degree of unbalancedness of neighbor cell base station is obtained, if uplink downlink degree of unbalancedness Meet default equilibrium condition, namely current neighbor cell is uplink downlink Balance Treatment state, then RNC User equipment is controlled according to default balance parameters value weight matched adjacent zone CIO parameters.

Specifically, as a kind of embodiment, RNC is provided with equilibrium condition in advance, it is current for judging Whether the uplink downlink of neighbor cell base station reaches expected poised state.What is be pre-configured with matches somebody with somebody condition again It can be default balance threshold value.

For example, after uplink downlink degrees of unbalancedness of the RNC according to default frequency acquisition neighbor cell base station, If link degree of unbalancedness is less than the balance threshold value being pre-configured with, RNC judges current neighbor cell Base station uplink downlink is poised state.

Then, RNC matches somebody with somebody UE adjacent area CIO parameters according to default balance parameters value again.It is default flat The parameter value that weighs can be 0db, can also be other numerical value, can flexibly set according to actual needs.

The CIO configuration parameters that RNC can weigh matched adjacent zone are CIO=0db.Then, RNC is to neighbor cell In each UE send control message, control message carries the CIO configuration parameters of adjacent area.

Each UE in neighbor cell is obtained after RNC control message, matches somebody with somebody its adjacent area again according to control message CIO parameters be 0db.Hereafter, each UE in neighbor cell to adjacent area move when, do not consider further that adjacent area The offset of pilot channel quality.

Thus, in the state of downlink reaches balance on adjacent cells, it is to avoid because of the skew of cell individual character Caused neighbor cell uplink downlink is uneven.

In the present embodiment, if uplink downlink degree of unbalancedness meets default equilibrium condition, control is used Family equipment is according to default balance parameters value weight matched adjacent zone CIO parameters.The present embodiment is by presetting balance strip Part, when the uplink downlink degree of unbalancedness of neighbor cell base station meets equilibrium condition, control UE matches somebody with somebody again Adjacent area CIO parameters, it is achieved thereby that ascending load difference in neighbor cell base station is smaller, up-downgoing chain Road restore balance state when, it is to avoid UE abnormal generation soft handovers when mobile are caused to neighbor cell base station Uplink interference, completes and CIO parameters is moved according to the uplink downlink real-time status of neighbor cell base station State is adjusted.

Further, reference picture 4, CIO methods of adjustment fourth embodiment of the present invention provides a kind of CIO and adjusted Adjusting method, based on the embodiment shown in above-mentioned Fig. 2, before the step S31, in addition to：

Step S40, the absolute value for obtaining the uplink downlink degree of unbalancedness.

After the uplink downlink degree of unbalancedness of cell base station is obtained, RNC judges currently whether meet CIO The uneven condition of parameter.

As a kind of embodiment, first, RNC obtains the absolute value of current uplink downlink degree of unbalancedness.

Step S50, judge whether the absolute value of the uplink downlink degree of unbalancedness reaches default imbalance Threshold value.

RNC is provided with uneven threshold value in advance, and the link for assessing current neighbor cell base station is uneven Weighing apparatus degree.

If current uplink downlink degree of unbalancedness absolute value is less than uneven threshold value, up-downgoing is judged The absolute value of link degree of unbalancedness is not up to default uneven threshold value；If current uplink downlink is not Degree of balance absolute value is more than or equal to uneven threshold value, then judges the absolute of uplink downlink degree of unbalancedness Value has reached default uneven threshold value.

Thus, result of determination is obtained.

If step S60, the absolute value of the uplink downlink degree of unbalancedness reach default uneven threshold value, Then judge that the uplink downlink degree of unbalancedness meets default uneven condition, and be transferred to execution step： S31。

After result of determination is obtained, if current uplink downlink degree of unbalancedness absolute value reach it is default not Balance threshold value, namely current neighbor cell the uneven degree of link than more serious, then RNC judges to work as Front upper and lower line link degree of unbalancedness meets default uneven condition, it is necessary to carry out CIO parameter reconfigurations.

Then, RNC is obtained according to uplink downlink degree of unbalancedness and/or the event detection parameter being pre-configured with Take the adjacent area CIO configuration parameters of each UE in cell；Control message is sent to UE, UE equipment roots are controlled According to adjacent area CIO configuration parameters, weight matched adjacent zone CIO parameters.

If current uplink downlink degree of unbalancedness absolute value is not up to default uneven threshold value, RNC judges currently carry out CIO parameter reconfigurations.

In the present embodiment, after uplink downlink degree of unbalancedness is obtained, uplink downlink is obtained uneven The absolute value of degree；Then, judge whether the absolute value of uplink downlink degree of unbalancedness reaches default injustice Weigh threshold value；If the absolute value of uplink downlink degree of unbalancedness reaches default uneven threshold value, sentence Determine uplink downlink degree of unbalancedness and meet default uneven condition, according to uplink downlink degree of unbalancedness and/ Or the event detection parameter being pre-configured with, obtain the adjacent area CIO configuration parameters of user equipment.The present embodiment By being pre-configured with uneven threshold value, only when the uplink downlink degree of unbalancedness of neighbor cell reaches injustice CIO parameter reconfigurations are carried out during the threshold value that weighs, it is to avoid frequent CI happened O parameter is matched somebody with somebody again, reduce RNC and UE burden, enhances the stability of each neighbor cell signal coverage, improves Consumer's Experience.

Further, reference picture 5, the embodiment of CIO methods of adjustment the 5th of the present invention provides a kind of CIO and adjusted Adjusting method, based on the embodiment shown in above-mentioned Fig. 4, after the step S40, in addition to：

Step S70, the absolute value according to the uplink downlink degree of unbalancedness and the record sheet being pre-configured with, Judge whether the variable quantity of the uplink downlink degree of unbalancedness reaches default variable threshold value, the note Record table have recorded the uneven condition of all previous satisfaction, and uplink downlink during weight matched adjacent zone CIO parameters is uneven Degree.

After uplink downlink degree of unbalancedness is obtained, RNC is according to current uplink downlink degree of unbalancedness and note Table is recorded, judges whether the variable quantity of current uplink downlink degree of unbalancedness meets variable threshold value.

Specifically, as a kind of embodiment, RNC is provided with record sheet in advance, record sheet, which have recorded, to be gone through It is secondary to meet uneven condition, carry out uplink downlink degree of unbalancedness during CIO parameter reconfigurations.

It should be noted that when uplink downlink degree of unbalancedness meets uneven condition, RNC is in control UE When carrying out CIO parameter reconfigurations, record carries out uplink downlink degree of unbalancedness during CIO parameter reconfigurations, and By in each uplink downlink degree of unbalancedness data Ji Lu record sheets.

RNC is obtaining uplink downlink according to the up-link capacity parameter of default frequency monitoring neighbor cell After degree of unbalancedness, the absolute value of current uplink downlink degree of unbalancedness is obtained.

Then, according to the record sheet being pre-configured with, the uneven condition of all previous satisfaction in current neighbor cell is searched, The uplink downlink degree of unbalancedness data of CIO parameter reconfigurations, are obtained apart from current time recent CIO The uplink downlink degree of unbalancedness of parameter reconfiguration, alternatively referred to as last uplink downlink degree of unbalancedness.

Then, RNC is according to the absolute value of current uplink downlink degree of unbalancedness and last uplink downlink The absolute value of degree of unbalancedness, obtains the variable quantity of current uplink downlink degree of unbalancedness.

It is DU to take current uplink downlink degree of unbalancedness, and last uplink downlink degree of unbalancedness is DU1, The variable quantity of current uplink downlink degree of unbalancedness is K, then RNC is according to DU absolute value and DU1 Absolute value obtain K.

As a kind of embodiment, K=︱ DU ︱-︱ DU1 ︱ are made.Calculating obtains variable quantity K.

If variable quantity K is less than or equal to default variable threshold value, judge that current uplink downlink is uneven The variable quantity of weighing apparatus degree is not up to default variable threshold value；If variable quantity K is more than default variable threshold value, Then judge that the variable quantity of current uplink downlink degree of unbalancedness reaches default variable threshold value.

It should be noted that variable quantity K calculation formula can also flexibly be set according to actual needs, example If K can be the absolute difference of DU absolute values and DU1 absolute values.Default variable threshold value is used for The variable condition of current uplink downlink degree of unbalancedness is assessed, concrete numerical value can flexibly be set according to actual needs Put.

Certainly, as another embodiment, RNC can also pre-set time interval threshold value, according to Record sheet, time that pilot tone matches somebody with somebody again is carried out and the time interval at current time exceedes time interval if last Threshold value, then directly judge that current uplink downlink degree of unbalancedness reaches default variable threshold value；If upper one It is secondary to carry out time for matching somebody with somebody again of pilot tone and the time interval at current time is less than time interval threshold value, then obtain and work as The variable quantity of front upper and lower line link degree of unbalancedness is judged.

Thus, the result of determination of the variable quantity to current uplink downlink degree of unbalancedness is obtained.

Corresponding, step S60 includes：

If step S61, the variable quantity of the uplink downlink degree of unbalancedness reach default variable threshold value, And the absolute value of the uplink downlink degree of unbalancedness reaches default uneven threshold value, then judges institute State uplink downlink degree of unbalancedness and meet default uneven condition.

After the result of determination to the variable quantity of current uplink downlink degree of unbalancedness is obtained, if when front upper and lower The variable quantity of line link degree of unbalancedness reaches default variable threshold value, then judges current neighbor cell base station Uplink downlink degree of unbalancedness variable quantity already exceed expection, pilot tone adjustment can be carried out.

Meanwhile, RNC judges whether the absolute value of current uplink downlink degree of unbalancedness reaches default injustice Weigh threshold value.

If the variable quantity of current uplink downlink degree of unbalancedness reaches default variable threshold value, and currently The absolute value of uplink downlink degree of unbalancedness reaches default uneven threshold value, then judges current up-downgoing Link degree of unbalancedness has met default uneven condition, and RNC controls UE carries out CIO parameter reconfigurations.

If the variable quantity of uplink downlink degree of unbalancedness is not up to default variable threshold value, or when front upper and lower The absolute value of line link degree of unbalancedness is not up to default uneven threshold value, then judges current up-downgoing chain Road degree of unbalancedness is unsatisfactory for default uneven condition.

In the present embodiment, obtain after current uplink downlink degree of unbalancedness, according to current uplink downlink The absolute value of degree of unbalancedness and the record sheet being pre-configured with, judge the change of current uplink downlink degree of unbalancedness Whether change amount reaches default variable threshold value, and record sheet have recorded the uneven condition of all previous satisfaction, match somebody with somebody again Uplink downlink degree of unbalancedness during the CIO parameters of adjacent area；If the change of current uplink downlink degree of unbalancedness Amount reaches default variable threshold value, and current uplink downlink degree of unbalancedness absolute value reach it is default Uneven threshold value, then judge that current uplink downlink degree of unbalancedness meets default uneven condition, User equipment is controlled to carry out CIO parameter reconfigurations.The present embodiment by assessing current uplink downlink not simultaneously Degree of balance absolute value and variable quantity, it is to avoid frequently control UE to carry out CIO parameter reconfigurations, alleviate UE Burden, improve Consumer's Experience.

Reference picture 6, CIO adjusting apparatus first embodiment of the present invention provides a kind of CIO adjusting apparatus, institute Stating CIO adjusting apparatus includes：

Monitoring modular 10, the up-link capacity parameter for monitoring multiple neighbor cell base stations.

The embodiment of the present invention is by monitoring user equipment dynamic in the running status of neighbor cell, control cell CIO (Cell individual offset, the skew of cell individual character) parameter of neighbor cell is adjusted, makes up-downgoing Link imbalance area is converted to soft handover area, substantially reduces or avoid in macro network because inter-cell uplink is negative Carry and there are problems that inter-cell uplink interference caused by larger difference, the uplink service experience of lifting macrocell.

The embodiment of the present invention monitors cell running status, control user equipment adjustment by CIO adjusting apparatus The CIO parameters of neighbor cell, carry out link management.CIO adjusting apparatus is laid out in RNC (Radio Network Controller, radio network controller) in.

Specifically, as a kind of embodiment, first, monitoring modular 10 monitors multiple neighbor cells in real time The up-link capacity parameter of base station, obtains the running status of current neighbor cell.

Monitoring modular 10, which monitors obtained up-link capacity parameter, to be included in the items that each cell base station is currently run Row capacity parameter, such as ascending load L (Load), noise incremental quantity RoT (Rise over Thermal noise) Deng.

Acquisition module 20, for according to the up-link capacity parameter, obtaining the multiple neighbor cell base station Uplink downlink degree of unbalancedness.

After the up-link capacity parameter of each cell base station is obtained, acquisition module 20 is obtained according to up-link capacity parameter Take the uplink downlink degree of unbalancedness of neighbor cell base station.

It is illustrated with currently having 2 neighbor cell base stations.

Then the real-time monitoring base station A and base station B of acquisition module 20 link running status, obtains base station A With base station B up-link capacity parameter, obtained up-link capacity parameter includes noise incremental quantity RoT and up negative Carry L etc..

Thus, acquisition module 20 obtains the uplink downlink degree of unbalancedness of neighbor cell base station.Obtain not The degree of balance characterizes the uneven degree of uplink downlink of current neighbor cell base station.

Match somebody with somebody module 30 again, if meeting default heavy with condition for the uplink downlink degree of unbalancedness, Control the cell individual character skew CIO parameters of the user equipment weight matched adjacent zone in the multiple neighbor cell.

After uplink downlink degree of unbalancedness is obtained, if uplink downlink degree of unbalancedness meets default heavy match somebody with somebody Condition, then control the cell individual character of user's weight matched adjacent zone in multiple neighbor cells to offset with module 30 again CIO parameters.

Specifically, as a kind of embodiment, be provided with advance with module 30 and match somebody with somebody condition again, for sentencing again The disconnected current CIO parameter reconfigurations for whether needing to carry out cell base station.What is be pre-configured with can be again with condition Default threshold value, the parameter such as uneven threshold value, balance threshold value.

When uplink downlink degree of unbalancedness reaches default uneven threshold value, then uplink downlink is judged Degree of unbalancedness meets default heavy with condition, and current adjacent cell uplink downlink is uneven more serious, The up-link of base station is heavily disturbed, influence user experience, now, again with module 30 need into Row CIO parameter reconfigurations.

Then, obtain and serviced belonging to current UE (User Equipment, user equipment) with module 30 again The neighbor cell of cell, namely UE adjacent area, reconfigure UE adjacent area CIO parameters.Match somebody with somebody module again The 30 each adjacent area CIO parameters matched somebody with somebody again can be the parameter value being pre-configured with, and can also be according to current uneven The configuration of weighing apparatus degree, it can also be according to 1A event measurement report parameter configurations, can also be other configurations Mode, can flexibly be set according to actual needs.It should be noted that in the embodiment of the present invention, UE is referred to User equipment.

Then, sent again with module 30 to UE in control message (Message control), control message Carry the CIO configuration parameters of each homogeneous frequency adjacent area of the affiliated serving cell of current UE, namely UE Each adjacent area CIO configuration parameters.

UE is received the control message sent with module 30 again after, obtains each adjacent area CIO that control message is carried Configuration parameter.When UE is being moved to neighbor cell, if detecting the descending primary common pilot of neighbor cell, Then after the pilot channel mass parameter of adjacent area is obtained, it is adjusted according to the CIO configuration parameters of current neighbor Pilot channel mass parameter, the pilot channel mass parameter after being offset.

If for example, UE current service cell ascending load is more than adjacent area ascending load, module is matched somebody with somebody again The 30 CIO parameters for configuring the adjacent area are 4dB, then UE can be carried when being moved to adjacent area in uneven area Preceding generation soft handover, reduces and the upward signal of cell base station is disturbed；If UE current service cell is up Load is less than adjacent area ascending load, then the CIO parameters for configuring the adjacent area with module 30 again are -4dB, then UE can be reduced and the upward signal of cell base station is disturbed when being moved to adjacent area with delayed generation soft handover.

Subsequently, monitoring modular 10 continues the up-link capacity ginseng according to default frequency monitoring neighbor cell base station Number, acquisition module 20 obtains the uplink downlink degree of unbalancedness of neighbor cell base station.If monitoring adjacent small The uplink downlink degree of unbalancedness of area base station changes, less than the balance threshold value being pre-configured with, and meets The default heavy adjacent area CIO parameters matched somebody with somebody condition, then reconfigure UE with module 30 again, obtain CIO and match somebody with somebody Put parameter.

Then, control message is sent to UE with module 30 again, control UE is configured according to new CIO to join The CIO parameters of number weight matched adjacent zone, it is to avoid the UE under neighbor cell base station uplink downlink poised state Upward signal interference to neighbor cell.

Hereafter, monitoring modular 10 continues the up-link capacity ginseng according to default frequency monitoring neighbor cell base station Number, acquisition module 20 obtains the uplink downlink degree of unbalancedness of neighbor cell base station, in uplink downlink not When the degree of balance is met again with condition, the adjacent area CIO parameter weights of UE in cell are controlled with module 30 again Match somebody with somebody.

In the present embodiment, monitoring modular 10 monitors the up-link capacity parameter of multiple neighbor cell base stations；So Afterwards, acquisition module 20 obtains the uplink downlink of multiple neighbor cell base stations not according to up-link capacity parameter The degree of balance；If uplink downlink degree of unbalancedness meets default heavy with condition, controlled again with module 30 many The CIO parameters of user equipment weight matched adjacent zone in individual neighbor cell.Due to neighbor cell base station ascending load Difference, can cause the presence of the uneven region of uplink downlink between neighbor cell, and the present embodiment passes through The up-link capacity parameter of monitoring neighbor cell base station, obtains the uplink downlink imbalance of neighbor cell in real time Degree, the uplink downlink degree of unbalancedness in neighbor cell reach it is default it is heavy match somebody with somebody condition when, RNC control UE, Namely user equipment, the CIO parameters of weight matched adjacent zone, so that UE is in moving process, being capable of basis Need to adjust soft handover area, the upward signal interference that reduction adjacent base station is subject to, while also reducing cell Middle user equipment is by being influenceed.When the ascending load of neighbor cell base station has differences, the present invention is real Apply example and effectively reduce the signal interference that cell base station is subject to, reduce the influence to user service in cell, Improve Consumer's Experience.

Further, reference picture 7, CIO adjusting apparatus second embodiment of the present invention provides a kind of CIO and adjusted Engagement positions, based on the embodiment shown in above-mentioned Fig. 6, the heavy condition of matching somebody with somebody includes uneven condition, described Include again with module 30：

Parameters unit 31, if meeting default uneven condition for the uplink downlink degree of unbalancedness, Then according to the uplink downlink degree of unbalancedness and/or the event detection parameter being pre-configured with, described use is obtained The adjacent area CIO configuration parameters of family equipment.

After the uplink downlink degree of unbalancedness of neighbor cell base station is obtained, if uplink downlink degree of unbalancedness Default uneven condition is met, namely current neighbor cell is the uneven processing state of uplink downlink, Then parameters unit 31 is obtained according to uplink downlink degree of unbalancedness and/or the event detection parameter being pre-configured with UE adjacent area CIO configuration parameters.

Specifically, as a kind of embodiment, the serving cell currently affiliated according to UE of parameters unit 31, Neighbour cell is obtained as UE adjacent area.

Then CIOs is DUs and R1A function, namely CIOs=(DUs, R1A).

If the serving cell ascending load belonging to UE is current is loaded less than adjacent area, parameters unit 31 is set The CIO parameters of the adjacent area are negative value, are easy to UE when being moved to the adjacent area, delayed generation soft handover, Reduce and the upward signal of cell base station is disturbed.Then parameters unit 31 can set the CIOs=- of the adjacent area ︱ R1A ︱, may be arranged as DUs and R1A other functions, can flexibly set according to actual needs.

Thus, parameters unit 31 has obtained UE adjacent area CIO configuration parameters.

Serving cell of the parameters unit 31 according to belonging to each UE, weighs the CIO configuration parameters of matched adjacent zone respectively, Realize for the personalized heavy matched adjacent zone CIO configuration parameters of UE communications status.

Transmitting element 32, for sending control message to the user equipment, the control message is carried The adjacent area CIO configuration parameters of the user equipment.

After UE adjacent area CIO configuration parameters are obtained, transmitting element 32 sends control message to UE, UE new Intra Freq Cell List (new co-frequency neighbor cell list) are carried in control message.

Include the CIO configuration parameters of each adjacent area of the configuration of parameters unit 31 in each neighboring BS information.

Match somebody with somebody unit 33 again, for controlling the user equipment according to the adjacent area CIO configuration parameters, match somebody with somebody again The adjacent area CIO parameters of the user equipment.

Transmitting element 32 is sent after control message to UE, controls user equipment according to adjacent area with unit 33 again CIO configuration parameters, again with its adjacent area CIO parameters.

If the pilot channel mass parameter after the skew of adjacent area meets 1A event measurement report conditions, judge to touch 1A events are sent out, the measurement report of the adjacent area is reported to RNC.If the pilot channel quality after the skew of adjacent area Parameter is unsatisfactory for 1A event measurement report conditions, then judges not triggering 1A events, not to again with unit 33 Report the measurement report of the adjacent area.

Received again with unit 33 after UE measurement report, control UE carries out soft handover.Hereby it is achieved that UE soft handovers it is in advance or delayed so that reduce neighbor cell uplink downlink it is uneven caused by up letter Number interference.

Currently to there are 2 neighbor cell base stations to be illustrated.

When current pilot channel mass parameter meets the 1A event measurement report conditions pre-set, UE reports current measurement report to RNC.UE is controlled to carry out soft cut according to measurement report with unit 33 again Change.

Now, judge current uplink downlink degree of unbalancedness meet it is default it is heavy match somebody with somebody condition, then transmitting element 32 UE respectively into each cell sends control message, reconfigures adjacent area with the control of unit 33 UE again CIO parameters.

For the UE in A cells, because the adjacent area of UE in A cells is B cells, then match somebody with somebody unit again UE in 33 control A cells matches somebody with somebody the CIO parameters of B cells again；For the UE in B cells, due to UE adjacent area is A cells in B cells, then controls the UE in B cells again small with A with unit 33 again The CIO parameters in area.

It is used as a kind of embodiment, reference picture 12.

The CIO configuration parameters with B cells are CIOb=DU-R1A, wherein DU to parameters unit 31 again>R1A. Then, UE of the transmitting element 21 into A cells sends control message, and control message carries B cells CIO configuration parameters CIOb.

UE in A cells is obtained after control message, matches somebody with somebody the CIO parameters of B cells again according to control message For DU-R1A.Hereafter, the UE in A cells to B cells move when, it is necessary to by the base station B detected Pilot channel mass parameter adds the pilot channel mass parameter after CIOb is offset.Then, then judge Whether the pilot channel mass parameter after skew meets 1A event measurement report conditions.

When UE row bounds in arrival in A cells, the pilot channel mass parameter after skew meets 1A UE is to again with the reporting measurement report of unit 33 in event measurement report condition, triggering 1A events, A cells Accuse so that UE can advance to up boundary generation soft handover in A cells, realizing will be former uneven Heng Qu is converted to soft handover area, reduces the upward signal that UE is caused to base station B in former uneven area and does Disturb.

Meanwhile, parameters unit 31 can the CIO configuration parameters with A cells be again CIOa=-R1A.So Afterwards, UE of the transmitting element 32 into B cells sends control message, and control message carries A cells CIO configuration parameters CIOa.

UE in B cells is obtained after control message, matches somebody with somebody the CIO parameters of A cells again according to control message For-R1A.Hereafter, the UE in B cells to A cells move when, it is necessary to which the base station A detected is led Frequency channel quality parameter adds the pilot channel mass parameter after CIOa is offset.Then, then judge partially Whether the pilot channel mass parameter after shifting meets 1A event measurement report conditions.

When UE reaches descending boundary in B cells, the pilot channel mass parameter after skew meets 1A UE is to again with the reporting measurement report of unit 33 in event measurement report condition, triggering 1A events, B cells Accuse so that UE can be with delayed to just generation soft handover at descending boundary in B cells, it is to avoid B cells The upward signal interference that soft handover is caused to base station B occurs to early in middle UE, while alleviating base station A's Ascending load is born.

It is used as another embodiment, reference picture 13.

The CIO configuration parameters with B cells are CIOb=DU to parameters unit 31 again.Then, transmitting element 32 UE into A cells sends control message, and control message carries the CIO configuration parameters of B cells CIOb。

UE in A cells is obtained after control message, matches somebody with somebody the CIO parameters of B cells again according to control message For DU.Hereafter, the UE in A cells to B cells move when, it is necessary to by the base station B pilot tones detected Channel quality parameter adds the pilot channel mass parameter after CIOb is offset.Then, then judge skew Whether pilot channel mass parameter afterwards meets 1A event measurement report conditions.

When UE row bounds in arrival in A cells, the pilot channel mass parameter after skew meets 1A UE is to again with the reporting measurement report of unit 33 in event measurement report condition, triggering 1A events, A cells Accuse so that soft handover occurs for the region that UE can be advanceed to beyond row bound in A cells, not only real Show and former uneven area is converted into soft handover area, and expanded soft handover area, not only reduced original The upward signal interference that UE is caused to base station B in uneven area, also reduces A cell portion users and sets The standby upward signal interference caused to base station B.

The CIO configuration parameters with A cells are CIOa=-DU-R1A or CIOa=-DU to parameters unit 31 again. Then, the UE in the cell of transmitting element 32 sends control message, and control message carries A cells CIO configuration parameters CIOa.

UE in B cells is obtained after control message, matches somebody with somebody the CIO parameters of A cells again according to control message. Hereafter, the UE in B cells to A cells move when, it is necessary to by the base station A pilot channel matter detected Amount parameter adds the pilot channel mass parameter after CIOa is offset.Then, then judge skew after leading Whether frequency channel quality parameter meets 1A event measurement report conditions.

If CIOa=-DU-R1A, when row bound in UE arrival in B cells, the pilot tone after skew Channel quality parameter meets 1A event measurement report conditions, triggers 1A events；If CIOa=-DU, When UE does not reach upper row bound in B cells, namely beyond upper row bound, the pilot channel after skew Mass parameter meets 1A event measurement report conditions, triggers 1A events.

Trigger after 1A events, UE is to again with the reporting measurement reports of unit 33 in B cells so that B is small Soft handover occurs for the region that UE can be advanceed to beyond up boundary or upper row bound in area, not only real Show and former uneven area is converted into soft handover area, and expanded soft handover area, not only reduced original The upward signal interference that UE is caused to base station A in uneven area, also reduces B cell portion users and sets The standby upward signal interference caused to base station A.

Meanwhile, the CIO configuration parameters with B cells are CIOb=-R1A to parameters unit 31 again.Then, UE in the cell of transmitting element 32 sends control message, and control message carries the CIO configurations of B cells Parameter CIOb.

UE in A cells is obtained after control message, matches somebody with somebody the CIO parameters of B cells again according to control message For-R1A.Hereafter, the UE in A cells to B cells move when, it is necessary to which the base station B detected is led Frequency channel quality parameter adds the pilot channel mass parameter after CIOb is offset.Then, then judge partially Whether the pilot channel mass parameter after shifting meets 1A event measurement report conditions.

When UE reaches descending boundary in A cells, the pilot channel mass parameter after skew meets 1A UE is to again with the reporting measurement report of unit 33 in event measurement report condition, triggering 1A events, A cells Accuse so that UE can be with delayed to just generation soft handover at descending boundary in A cells, it is to avoid A cells The upward signal interference that soft handover is caused to base station A occurs to early in middle UE, while alleviating base station B's Ascending load is born.

Hereby it is achieved that each UE weights matched adjacent zone CIO parameters in control neighbor cell.
