Embodiment
In the embodiment of the invention, the value of negotiable mobility parameter between the eNB, adjacent then a plurality of eNB are simultaneously with the value of mobility parameter adjustment to negotiation, suitably dwindle coverage with the eNB that realizes heavy load, lighten the load, the eNB that is adjacent suitably increases coverage, strengthens the covering to the scope that eNB dwindled of heavy load, improved the communication quality of edge UE, reduced edge UE the possibility that table tennis switches takes place.
In the present embodiment, an eNB may cover one or more sub-districts, if corresponding eNB in a plurality of sub-districts, then the mobility parameter between these a plurality of sub-districts is determined to get final product by this eNB, if the corresponding a plurality of eNB in a plurality of sub-districts, then the mobility parameter between these a plurality of sub-districts need be by consulting between a plurality of eNB, and present embodiment relates generally to the process of consulting between a plurality of eNB.
Referring to Fig. 1, the main method flow process of balanced load is as follows in the present embodiment:
Step 101: an eNB receives the adjustment information of the first adjacent area mobility parameter that the 2nd eNB sends.Adjustment information can be the information of expression adjusting range, or is adjusting range itself.
Step 102: an eNB determines the relevant information of the first adjacent area mobility parameter according to the adjustment information of receiving, and sends to the 2nd eNB.The relevant information of mobility parameter comprises the value or the adjustment amount of mobility parameter.
Step 103: the 2nd eNB determines the relevant information of the second adjacent area mobility parameter according to the relevant information of the first adjacent area mobility parameter.
Step 104: an eNB adjusts according to the relevant information of the first adjacent area mobility parameter, and the 2nd eNB adjusts according to the relevant information of the second adjacent area mobility parameter.
In order to alleviate the load of sub-district 0, the coverage that need dwindle sub-district 0 makes user's switching at 0 edge, sub-district or arrives adjacent sub-district again.To switch to example, when the 1:Mn+Ofn+Ocn-Hys that satisfies condition＞Ms+Ofs+Ocs+Off, UE 0 switches to neighbor cell from the sub-district, and wherein Mn is the measured value of adjacent area, and ofn is the deviant of the frequency that adopts of adjacent sub-district, Ocn is the sub-district individual character skew of adjacent area, Hys is sluggish parameter, and Ms is the measured value of this sub-district, and Ofs is the deviant of the frequency of this sub-district employing, Ocs is the sub-district individual character skew of this sub-district, and off is the offset parameter of A3 incident.Distortion can get to condition 1: Mn＞Ms+ (Ofs+Ocs+Off+Hys)-(Ofn+Ocn), because Mn and Ms are the measured value of objective reality, so only need to (Ofs+Ocs+Off+Hys)-(Ofn+Ocn) adjust.In order to explain the convenience with message transmission, make Ai=Ofs+Ocs+Ofi+Hys, Bi=Ofn+Ocn, Ai represent the mobility parameter sum of this sub-district, Bi represents the mobility parameter sum of an adjacent sub-district of this sub-district.Present embodiment is to consider the influence of many-sided factor to coverage, just makes Ai=Ofs+Ocs+Ofi+Hys, Bi=Ofn+Ocn.If the process and the transinformation of simplified equalization load, then condition 1 can be reduced to Mn+Ocn＞Ms+Ocs, promptly Ai comprises Ocs at least, Bi comprises Ocn at least.For reselecting parameters, then Ai comprises Qhyst (the sub-district deviant of this sub-district) at least, and Bi comprises Qoffset (two sub-district between sub-district deviant) at least.Each sub-district all disposes Ai and Bi, realizes balanced load by the value of adjusting Ai and Bi.
Can adopt existing message alternately between the one eNB and the 2nd eNB, also can adopt newly-designed message, introduce in detail below by two embodiment.
Referring to Fig. 2, the method flow of balanced load is as follows when adopting existing signaling to hold consultation in the present embodiment:
Covering a sub-district with an eNB is example, and referring to shown in Figure 3, heavy load or overload appear in sub-district 0, and sub-district 1-6 that need be adjacent with self carries out load balancing to be handled.ENB0 coverage cell 0, eNB1 coverage cell 1, by that analogy.
Step 201:eNB0 finds that the load level value of sub-district 0 is higher than load thresholding Th0, shows that heavy load or overload appear in sub-district 0, need carry out load balancing with neighbor cell.
Step 202:eNB0 sends resource status request (Resource StatusRequest) message to eNB1-6 respectively, consults with request.Present embodiment utilizes the vacant field in the resource status request message to carry A 0With

The value of (i=1,2...6).
Figure B2009101656303D0000052
Superscript represent the sign of this sub-district, subscript is represented the sign of adjacent sub-district.If in eNB1-6, disposed A 0With
Figure B2009101656303D0000053
Then can not carry A 0With
Figure B2009101656303D0000054
Value.Perhaps, eNB0 is periodically with A 0With
Figure B2009101656303D0000055
Send to eNB1-6, then also can in the resource status request message, not carry; The A that eNB1-6 received according to the last time 0With
Figure B2009101656303D0000056
Carry out follow-up judgement and calculating.
Step 203:eNB1-6 has judged whether load-bearing capacity, if having, then replys resource status response (Resource Status Response) message, if do not have, does not then reply message.The deterministic process of this step adopts prior art.ENB1-6 all has the ability to load in the present embodiment, then continues step 204.If eNB1-6 does not all have capacity load, then eNB0 can initiate the request of load balancing after a period of time again, perhaps asks Operation Administration and Maintenance (OAM) equipment to force load balancing.
Step 204:eNB1-6 judges whether to agree to consult, if agree, then continues step 205, otherwise continues step 206.For example, eNB1-3 agrees to consult, and eNB4-6 disagrees with negotiation.
Step 205:eNB1-3 calculates the adjusting range about the adjacent area mobility parameter of the sub-district 0 of self.That is, eNB1-3 calculates respectively
Figure B2009101656303D0000061
Adjusting range.
Step 206:eNB4-6 sends expression to eNB0 and disagrees with that the resource status of negotiation upgrades (ResourceStatus Update) message, promptly comprises the flag bit that negotiation is disagreed with in expression in the resource status updating message, is that negotiation is disagreed with in 0 expression as flag bit.
If eNB1-3 also sends the resource status updating message that negotiation is disagreed with in expression to eNB0, then finish this flow process, eNB0 can initiate the request of load balancing after a period of time again, perhaps asks OAM to force load balancing.
Step 207:eNB1-3 sends to eNB0 and agrees the resource status updating message of consulting, and this resource status updating message also carries
Figure B2009101656303D0000062
Adjusting range.As the flag bit in the resource status updating message is 1, agrees to consult.
Present embodiment utilizes the vacant field in the resource status updating message to carry flag bit and adjusting range.
Step 208:eNB0 selects one or more eNB to carry out equilibrium from the eNB1-3 that agrees to consult.For example, eNB0 selects eNB1-2 to carry out equilibrium.
Step 209:eNB0 determine according to the adjusting range received corresponding selection eNB adjacent area mobility parameter (promptly
Figure B2009101656303D0000063
) value or adjustment amount.
Step 210:eNB0 sends to corresponding eNB by eNB config update (eNB Configuration Update) message with the value or the adjustment amount of adjacent area mobility parameter.For example, eNB0 will Value or adjustment amount send to eNB1-2.
Present embodiment utilizes the vacant field in the eNB configuration update message to carry the value or the adjustment amount of parameter update time and mobility parameter.
Step 211:eNB1-2 determines self adjacent area mobility parameter with respect to eNB0 according to the value or the adjustment amount of the adjacent area mobility parameter of receiving, promptly eNB1-2 determines respectively
Figure B2009101656303D0000065
With
Figure B2009101656303D0000066
ENB1-2 also returns the correct response of eNB configuration (eNB Configuration Acknowledge) message, the value or the adjustment amount of the mobility parameter that expression can be accepted to receive.
Step 212:eNB0 and eNB1-2 adjust according to the value or the adjustment amount of the adjacent area mobility parameter of self, to realize load balancing.
After eNB0-2 adjusts adjacent area mobility parameter, in system information, carry the value of adjusted adjacent area mobility parameter with broadcast mode, and pass through beep-page message untill further notice UE receives broadcasting when the next system information update cycle arrives system information, so that UE upgrades.
The adjacent area mobility parameter of eNB0-2 changes, and makes the UE be positioned at cell edge switch or gravity treatment according to the adjacent area mobility parameter after upgrading, from the sub-district 0 switch or gravity treatment to sub-district 1-2, thereby alleviated the load of sub-district 0, realized load balancing.
In the present embodiment, the criterion of step 204 is with respect to step 203 strictness.With the handoff procedure is example, and the condition 1 that switches to sub-district j from cell i is M j＞M i+ (A i-B j); 1≤i, j≤N and i ≠ j, the condition 2 that switches to cell i from sub-district j is M i＞M j+ (A j-B i); 1≤i, j≤N and i ≠ j.Can get according to condition 1 and 2: A i+ A j＜B i+ B jIn order to prevent that table tennis from switching, and then needs the 3:A that satisfies condition i+ A j＞B i+ B jIn step 204, eNB1-6 judges whether to meet the following conditions:
Figure B2009101656303D0000071
Wherein, j=1,2...6, h1 and h2 are default mobility parameter threshold value, can according to mobile robustness optimization (Mobility robustness optimization, MRO) or the engineering experience setting.
If satisfy, then agree to consult, otherwise disagree with negotiation, show that this locality does not have ability and neighbor cell to carry out load balancing.
For example, eNB1 agrees to consult, then basis in step 205 But excursion, as-5～5, can be directly with
Figure B2009101656303D0000074
But the excursion conduct
Figure B2009101656303D0000075
But excursion, perhaps foundation

Figure B2009101656303D0000079
But span and excursion all can in the sub-district 0 about the adjusting range of the adjacent area mobility parameter of sub-district 1.
In step 207, be example with eNB1, the adjusting range that eNB1 carries in the resource status updating message can be But excursion, as-5～5,, increase the coverage of sub-district 1-6 because present embodiment is to wish the coverage dwindle sub-district 0, so

Adjusting range determine Ofn 1And Ocn 1Adjusting range.Perhaps, eNB1 is obtaining in step 205
Figure B2009101656303D0000083
Adjusting range after, further obtain Ofn 1And Ocn 1Adjusting range, in the resource status updating message of step 207, carry Ofn then 1And Ocn 1Adjusting range.Obtain Ofn 1And Ocn 1The mode of adjusting range will as: eNB1

But excursion on average arrive Ofn 1And Ocn 1On, i.e. Ofn 1And Ocn 1But excursion be-2.5～2.5; Perhaps, be Ofn in advance 1And Ocn 1Scope weight w and 1-w are set, 0＜w＜1, then Ofn 1But excursion be-5w～5w Ocn 1But excursion-5 (1-w)～5 (1-w).
In step 208, it is multiple that eNB0 selects the mode of adjacent eNB to have, as select any selection, perhaps selects the lightest one or more eNB of load, and perhaps selection is received
Figure B2009101656303D0000085
One or more eNB etc. of adjusting range maximum.
In step 209, if eNB0 only receives the adjacent area mobility parameter that eNB1 returns

Adjusting range, then in adjusting range, from the value (as 15) of the first current adjacent area mobility parameter to determining the value that value is an adjacent area mobility parameter the boundary value (as 20) of adjusting direction at random; Perhaps, definite boundary value (as 20) of adjusting direction is the value of adjacent area mobility parameter in adjusting range.For example, sub-district 0 heavy load, wishing will
Figure B2009101656303D0000087
Transfer greatly, then select the maximum (as 20) in the adjusting range to be the value of adjacent area mobility parameter.
If eNB0 receives the adjacent area mobility parameter that eNB1-2 returns

Overlapping scope in determine a value at random, perhaps from With
Figure B2009101656303D00000813
Overlapping scope in determine to adjust direction boundary value be the value of adjacent area mobility parameter.Perhaps:
ENB0 determines the mobility B parameter of eNB1-2 according to the load condition of sub-district 0 1-2As: but the corresponding relation of total excursion of default load level value and mobility parameter, and this corresponding relation is as shown in table 1:

Load level value f But total excursion
?90≤f 4
?80≤f＜90 3
?70≤f＜80 2
?...... ......
But eNB0 is according to total excursion of adjacent area mobility parameter corresponding in the current load level value question blank 1 in sub-district 0, but determine value according to total excursion of mobility parameter again, but promptly satisfy total excursion of adjacent area mobility parameter about the adjusting range sum of the adjacent area mobility parameter of eNB1-2 about the adjacent area mobility parameter of eNB1-2.Specific implementation has multiple, as: but will total excursion on average to each adjacent eNB, but for example total excursion is 4, then about the adjacent area mobility parameter of eNB1-2

Include a plurality of mobility parameters, then determine the value or the adjustment amount of adjusted each mobility parameter referring to the mode that for each parameter the scope weight is set in the step 207.
Referring to Fig. 4 A, the method flow of balanced load is as follows when adopting newly-designed signaling to hold consultation in the present embodiment:
Covering a sub-district with an eNB is example, and referring to shown in Figure 3, heavy load or overload appear in sub-district 0, and sub-district 1-6 that need be adjacent with self carries out load balancing to be handled.ENB0 coverage cell 0, eNB1 coverage cell 1, by that analogy.
Step 401:eNB0 finds that the load level value of sub-district 0 is higher than load thresholding Th0, shows that heavy load or overload appear in sub-district 0, need carry out load balancing with neighbor cell.
Step 402:eNB0 sends parameter configuration (Parameter Configuration) message to eNB1-6 respectively, consults with request.With the parameter configuration message that sends to eNB1 is example, and this message comprises the address of purpose eNB1, the sign of eNB0, can also comprise A 0And B 1Perhaps, eNB0 sends the resource status request message and consults with request, simultaneously or send parameter configuration message continuously, and to carry A 0And B 1
Step 403:eNB1-6 judges whether to agree to consult, if agree, then continues step 404, otherwise continues step 405.The detailed process of judging is referring to step 204.For example, eNB4-6 judges back refusal negotiation, and eNB1-3 judgement back is agreed to consult.
Step 404:eNB1-3 calculates the adjusting range about the adjacent area mobility parameter of the sub-district 0 of self.That is, eNB1-3 calculates respectively

Adjusting range.
Step 405:eNB4-6 sends expression to eNB0 and disagrees with negotiation parameter reconstruction (ParameterRecommendation) message.Parameter is rebuild message and is comprised the sign of source eNB, the address of purpose eNB, and whether expression agrees the flag bit consulted and the adjusting range of mobility parameter, if disagree with negotiation, then the adjusting range of mobility parameter can be sky.
Step 406:eNB1-3 sends to eNB0 and agrees negotiation parameter reconstruction message, and this parameter reconstruction message also carries adjusting range.
Step 407:eNB0 selects one or more eNB to carry out equilibrium from the eNB1-3 that agrees to consult.For example, eNB0 selects eNB1-2 to carry out equilibrium.
Step 408:eNB0 determine according to the adjusting range received corresponding selection eNB adjacent area mobility parameter (promptly

Value.ENB0 is execution in step 421 periodically, perhaps execution in step 421 after finding sub-district 0 heavy load.
Step 422:eNB1-6 judges whether to agree to consult, if agree, then continues step 424, otherwise continues step 423.
Step 423:eNB3-6 sends resource status updating message or the parameter reconstruction message that negotiation is disagreed with in expression to eNB0.Because the eNB3-6 refusal is consulted, so finish about the flow process of eNB3-6.
Step 424:eNB1-2 sends to eNB0 and agrees the message of consulting, and this message also carries
Figure B2009101656303D0000127
Adjusting range.
Step 425:eNB0 selects one or more eNB to carry out equilibrium from the eNB1-2 that agrees to consult.For example, eNB0 selects eNB1-2 to carry out equilibrium.
Step 426:eNB0 determines that according to the adjusting range of receiving the adjacent area of the eNB of corresponding selection covers the value or the adjustment amount of parameter.ENB0, as the mode of employing table 1 and makes the suitable parameters value in conjunction with the scope that eNB1-2 provides and selects according to the load balancing algorithm.
Step 427:eNB0 sends to corresponding eNB1-2 with the value or the adjustment amount of adjacent area mobility parameter.The value of adjacent area mobility parameter or adjustment amount can carry by eNB configuration update message or parameter update message.
Step 428:eNB1-2 determines self adjacent area mobility parameter with respect to eNB0 according to the value or the adjustment amount of the adjacent area mobility parameter of receiving.
Step 429:eNB0 and eNB1-2 adjust according to the value or the adjustment amount of the adjacent area mobility parameter of self, to realize load balancing.
Wherein, whether agree in the step 422 that the judgement of consulting comprises: judge whether this sub-district is the high priority sub-district, and the priority of sub-district can be disposed by OAM; Judge whether eligible
Figure B2009101656303D0000131
Judge what this locality calculated
Figure B2009101656303D0000132
Scope and acquisition
Figure B2009101656303D0000133
Term of reference whether common factor is arranged; If above-mentioned condition all satisfies, then agree to consult, otherwise refusal is consulted.ENB3-4 is because this sub-district is the sub-district of low priority and refuse to consult in the present embodiment; ENB5 is because do not satisfy condition And refusal is consulted; ENB6 is because can not get
Figure B2009101656303D0000135
Scope occur simultaneously and refusal is consulted.Wherein, eNB6 is owing to satisfy condition
Figure B2009101656303D0000136
So can further bear load, consider that from the load balancing angle eNB6 can agree to consult, and considers that from the mobility angle eNB6 refuses to consult.
The initial value of the mobility parameter of each sub-district all is to be provided with according to long-term engineering experience, is more satisfactory value.Adjusting the value of mobility parameter in the present embodiment, is in order to solve the problem that heavy load or overload appear in certain sub-district, and this problem may be interim.So wish after cell load alleviates, the mobility parameter to be returned to initial value.And the heavy load sub-district has dwindled coverage through the adjustment of mobility parameter, thereby has alleviated the load of this sub-district, has realized load balancing with neighbor cell simultaneously.When the load of heavy load sub-district reduced to a lower value, bigger scope was had the ability to cover in this sub-district, and also should consult with neighbor cell this moment, realizes load balancing.
Referring to Fig. 5, the method flow about the balanced load of light load sub-district in the present embodiment is as follows:
With existing signaling is that example describes.
Step 501:eNB0 finds that the load level value of sub-district 0 is lower than load thresholding Th1, shows that sub-district 0 is in the light load state, need carry out load balancing with neighbor cell.Wherein, Th1≤Th0.
Step 502:eNB0 determines the adjacent eNB of holding consultation.ENB0 can all hold consultation with eNB1-6, also can hold consultation with the eNB1-2 that consulted before, perhaps holds consultation etc. according to the relatively poor adjacent eNB of measurement report and measurement result.For example, eNB0 and eNB1-2 hold consultation.
Step 503:eNB0 sends to eNB1-2 by the value about the adjacent area mobility parameter of eNB1-2 of eNB configuration update message before will adjusting.Perhaps, eNB0 will send to eNB1-2 about the opposite number of the adjustment amount of the adjacent area mobility parameter of eNB1-2.During 0 heavy load, the adjustment amount that eNB0 sends may be 2 in the sub-district; 0 light hours in the sub-district, the adjustment amount that eNB0 sends may be-2.
Step 504:eNB1-2 returns eNB and disposes correct response message, the value or the adjustment amount of the mobility parameter that expression can be accepted to receive.
Step 505:eNB0 and eNB1-2 adjust according to the value or the adjustment amount of the adjacent area mobility parameter of self correspondence, to realize load balancing.
Be to make neighbor cell dwindle coverage by the value of adjusting the mobility parameter in the present embodiment, it all is acceptable reducing the scope usually.But in order to prevent that other factors from also having adjusted the value of mobility parameter, may make neighbor cell narrow down to unacceptable scope, eNB0 can send the resource status request message to the adjacent eNB of determining before sending the eNB configuration update message.The eNB that receives this message carries out the judgement in step 203 and the step 204, after agreeing to consult, send to eNB0 and to agree the resource status updating message of consulting, and this resource status updating message also carries adjusting range.ENB0 determines the value or the adjustment amount of the adjacent area mobility parameter of self correspondence according to the adjusting range received.A kind of implementation among Fig. 2 is to determine the value or the adjustment amount of mobility parameter according to the adjusting range upper limit of mobility parameter, and be the coverage of wishing to enlarge sub-district 0 at this moment, dwindle the coverage of neighbor cell, so need to determine the value or the adjustment amount of mobility parameter according to the adjusting range lower limit of mobility parameter.
