Based on this, in some embodiments, this method can also include:
When the load of the source cell is more than load balancing threshold value, at least one adjacent area of the source cell Xiang Suoshu sends negative
Lotus interaction request；
Receive the feedback loading information that each adjacent area issues；
When feedback loading information determines the adjacent area for existing and meeting load balancing condition based on the received, it is small to obtain the source
The corresponding user service information in area.
Wherein, feedback loading information is mainly the information on load of corresponding adjacent area, when practical application, is fed back to according to adjacent area
Feedback loading information judges whether the adjacent area meets load balancing condition, and there are the neighbours that at least one meets load balancing condition
Qu Shi, triggering obtain the corresponding user service information in source cell.
Here, when practical application, load evaluation can be carried out to set the period to source cell, the load in source cell is more than
Load balancing threshold value, and there are when the adjacent area that at least one meets load balancing condition, just triggering obtains the corresponding use in source cell
Family business information, i.e. execution step S201.
In addition, as big data platform depth Packet analyzing (DPI) technology and artificial intelligence technology are in mobile communication field
Using the user information that the network equipment can obtain becomes increasingly abundant, therefore can be by different channels (for example, can pass through
The technology platforms such as drive test are adopted or minimized firmly to soft adopt of big data platform, signaling) get customer position information, user's measurement report
The information such as announcement, customer service XDR information.
Step S202: it using the user service information obtained, is determined from the user of source cell and waits moving comprising at least one
Divert from one use to another the target migrated users group at family；
Specifically, according to user's measurement report and customer position information, at least one is filtered out from the user of source cell
Candidate user to be migrated forms candidate migrated users group；
Using customer service XDR information, the target migrated users group is determined from the candidate migrated users group.
Wherein, candidate migrated users group is filtered out as preliminary classification screening according to user's measurement report and customer position information
Process, in some embodiments, the specific implementation of this process may include:
For each user of the source cell, according to user's measurement report, determine that corresponding user receives the target
The signal strength of cell；
According to customer position information, the distance between the corresponding user and the target cell base station are determined；
Classified according to the signal strength and the distance to the corresponding user, obtains classification results；
Classification results are met into the user of transition condition as candidate user to be migrated.
When practical application, can according to the signal strength for receiving adjacent area and with the distance between neighbor base station by user into
Row classification, for example it is segmented into following four class:
First kind user, signal strength is strong and base station distance is close；
Second class user, signal strength is medium and base station distance is medium；
Third class user, signal strength is weak and base station distance is remote；
4th class user, signal strength is strong or base station distance is close.
| Class of subscriber | Classification description | Priority |
| First kind user | Signal strength is strong and base station distance is close | First priority |
| Second class user | Signal strength is medium and base station distance is medium | Second priority |
| Third class user | Signal strength is weak and base station distance is remote | Third priority |
| 4th class user | Signal strength is strong or base station distance is close | Second priority |
The mapping table of table 1 class of subscriber and priority
Here it is possible to corresponding distance threshold is set, it is true by compared with distance threshold, coming with the distance between base station
It is close, medium or remote for determining the distance between user and base station.
And after determining class of subscriber, determine that user is placed into the priority of candidate migrated users group according to class of subscriber,
And class of subscriber and the corresponding relationship of priority are as shown in table 1.
After classification, user can be ranked up according to priority height, and demand is shifted based on actual loading, to sequence
User afterwards screens, and filters out several high users (user for meeting transition condition) of priority and is placed in candidate migration
In user group.Wherein, the first priority is higher than the second priority, and the second priority is higher than third priority.Here, as an example
It, can priority is high that (i.e. the first priority, signal strength be strong and base station distance in the case where meeting load migration demand for son
User closely) shifts, it is intended to not influence customer service perception as much as possible.
In some embodiments, preliminary classification screening is carried out to the user in source cell and obtains candidate migrated users group
Afterwards, using customer service XDR information, target migrated users group to be migrated is determined from the candidate migrated users group.
Specifically, delay sensitive screening is carried out to the candidate migrated users group after progress preliminary classification screening, and time delay is quick
Sense screening is, for the candidate user to be migrated of each of candidate migrated users group, using corresponding customer service XDR information,
Delay sensitive value is more than the user of setting sensitivity threshold from the candidate migrated users group by the delay sensitive value for determining business
It screens out.
In the present embodiment, the purpose for carrying out delay sensitive screening is screened out to the user of high delay sensitive business,
It is intended to avoid switching over transfer to the user of delay sensitive as far as possible.
When practical application, specific implementation process may include: to judge business according to the business tine of customer service XDR information
It is that mobile phone operation is used in backstage execution or user to execute, specifically, according to the operation of application program in business tine
Subprogram, judgement are users using mobile phone operation, again without mobile phone operation is used and only business backstage is being run, if being only
Running background then judges without delay sensitive, if mobile phone operation is used in user, needs to identify user's industry currently in use
Whether business belongs to high delay sensitive business (such as live streaming, game on line etc.), if user's business currently in use is to belong to
High delay sensitive business then rejects the user from candidate migrated users group.In this way, realizing load balancing more high-qualityly.
When practical application, portfolio can also be further considered, the big user of portfolio is switched transfer.
Based on this, in some embodiments, for each user in the candidate migrated users group after screening out, using corresponding
Customer service XDR information, determine the corresponding uplink and downlink portfolio of business；
User by uplink and downlink portfolio lower than traffic volume threshold screens out from the candidate migrated users group after described screen out.
Here, the process for carrying out further portfolio screening to the user to be migrated after progress delay sensitive screening can claim
For portfolio screening process.
In the embodiment of the present invention, after the user to high delay sensitive business screens out, further to portfolio
Small user screens out, it is intended to reduce the user for being switched transfer when carrying out load balancing as far as possible, can guarantee industry in this way
The continuity of business promotes user experience.
When practical application, the customer service XDR information includes the uplink and downlink portfolio that customer service generates, can be direct
The uplink and downlink portfolio of customer service generation is obtained from customer service XDR information, then according to the size of uplink and downlink portfolio,
Candidate user to be migrated after delay sensitive screens is ranked up, determines traffic volume threshold according to ranking results；Then
Uplink and downlink portfolio is screened out from the candidate migrated users group lower than the user of traffic volume threshold.
It should be noted that in the present embodiment, retain the big user of portfolio in target migrated users group, to realize pair
The big user of portfolio carries out cell switched and transferred, may be implemented while meeting load balancing demand, reduces being transferred
User volume.
View of the above, it will be seen that in order to realize good load balancing process, in the embodiment of the present invention, Ke Yitong
Above three screening process is crossed to determine user to be migrated, i.e., is sieved by preliminary classification screening, delay sensitive screening and portfolio
Process is selected to determine user to be migrated.
Step S203: balance parameters corresponding with Target cell negotiation target migrated users group；
Here, to may include: the network equipment interact load balancing with Target cell by X2 interface joins for negotiations process
Number Adjusted Option, Target cell judge whether that the parameter recommendation of source cell can be received, if can be with parameter negotiation success；It is no
Then, Target cell reply parameter amending advice, both sides re-start parameter-negotiation procedure；After negotiation, source cell and target
Cell respectively carries out parameter adjustment according to scheme.
In addition, in source cell there are when the adjacent area that at least two meet load balancing condition, method may be used also in the present embodiment
To include: to determine corresponding target migrated users group for each adjacent area；It will be used comprising the least target migration of user to be migrated
The corresponding adjacent area of family group is determined as Target cell.Specifically, when only one meets the adjacent area of load balancing condition, directly will
This adjacent area is determined as Target cell；In addition, when there are two the adjacent area for meeting load balancing condition above, by the least mesh of user
The corresponding adjacent area of mark migrated users group is determined as Target cell.In addition, it should be noted that, being selected in the present embodiment few as far as possible
User carries out cell switching, can preferably realizing the business sense for not influencing user in cell while cell load equilibrium
Know.
Step S204: based on determining balance parameters are negotiated, load balancing is carried out to source cell.
Here, negotiate the process of balance parameters, the negotiations process of parameter is actually corresponded to migration path, pass through association
Quotient, determine one it is optimal the target migrated users group of source cell is migrated to the migration path of Target cell, in this way, can be based on
Migration is better achieved in optimal migration path, that is, preferably can carry out load balancing to source cell.
Load-balancing method provided in an embodiment of the present invention obtains the user service information of source cell；Utilize the use of acquisition
Family business information determines the target migrated users group comprising at least one user to be migrated from the user of source cell；With target
Cell negotiates the corresponding balance parameters of target migrated users group；Based on determining balance parameters are negotiated, source cell is loaded
It is balanced.
The scheme of the embodiment of the present invention determines target migrated users group according to the user service information of source cell, and generates
For the load balancing parameter that source cell is interacted with Target cell, and negotiating to determine that target migrated users group is right with Target cell
After the balance parameters answered, load balancing is carried out to source cell.In the embodiment of the present invention, only the user of suitable transfer is turned
It moves, can realize the service-aware for not influencing user in cell while cell load equilibrium.
In addition, source cell is corresponding each when there are multiple adjacent areas for meeting load balancing condition in the embodiment of the present invention
The adjacent area for meeting condition filters out the target migrated users group for being suitable for load balancing transfer；Then from multiple targets
