Specific implementation mode
Below in conjunction with drawings and examples, the specific implementation mode of the present invention is described in further detail.Following reality
Example is applied for illustrating the present invention, but is not limited to the scope of the present invention.
The scene of wireless network is largely divided into 3 classes：The same covering scene of homogeneous frequency adjacent covering scene, alien frequencies, F-D layerings/macro
Micro- networking scene.When serving cell load is excessively high, it is as follows to analyze this 3 class high load scenarios：
One, homogeneous frequency adjacent covering scene
Under the scene if using LB, since switching user is located in the switching band of two neighboring communities, service is small
After user in area is switched to adjacent area, pingpang handoff is easy tod produce.It also contemplates for existing using anti-table tennis strategy alleviation pingpang handoff
As, but the strategy can influence the mobility of user.Therefore, in such a scenario, LB application effects are bad；Under the scene if
Using MLB, by adjusting handoff parameter, switching band is moved to high load capacity cell, user is promoted to be switched to underload cell, and
And since handoff parameter is to adjust in pairs, it also can effectively prevent switchback and ensure that the mobility of user；Scene master
If single layer network covers, CA can not be also applied.
Two, the same covering scene of alien frequencies
If being switched to neighboring community using LB selection users, because neighbor cell signal is strong, therefore can effectively prevent back
It cuts.LB significant effects, it can be achieved that minizone load balance.If using MLB, by adjusting handoff parameter, it can be achieved that cell
Between load balance.But since MLB can not achieve the accurate selection to user, effect is not so good as LB；Multiband, can with covering
Start CA functions, realizes the load balance of two carrier waves.
Three, F-D layerings/macro and micro networks scene
When D frequency range loads are excessively high, F-band cell load is low：If being switched to F using LB selection D frequency range intra-cell users
Frequency range cell, and since for F and D with covering, F-band cell signal is strong, can effectively prevent switchback at this time.LB significant effects, can be real
The load balance of existing minizone.If using MLB, by adjusting handoff parameter, part edge user is made to be switched to adjacent area, it can be real
The load balance of existing minizone.But since MLB can not achieve the accurate selection to user, effect is not so good as LB；Multiband covers
Lid can start CA, realize load balance.
When F-band cell load is excessively high, D frequency range cell loads are low：When considering using LB, it is necessary to reduce the switching door of LB
Limit, since F-band signal strength is due to D frequency range cells, is used though can select user at this time moves to underload D frequency range cells
Switchback of rattling easily occurs for family；If taking anti-table tennis strategy, and the mobility of user can be influenced.Therefore, under this scene, LB applications
It is ineffective.If using MLB, by adjusting handoff parameter, switching band D frequency range cells is moved, user is promoted to switch, and
It can effectively prevent switchback, significant effects of the MLB for balancing the load.Under this scene, since user focuses mostly in D frequency range cells
Edge, therefore, it is difficult to trigger the CA of D+F frequency ranges.
In conclusion three kinds of technologies respectively there are application scenarios, solve the problems, such as that serving cell load is excessively high under special scenes.It is right
For existing net, the high load capacity under all scenes cannot be solved the problems, such as by monotechnics and load is unbalanced.Therefore, this programme
A kind of application scheme that MLB and LB collaborations come into force is proposed, realizes the load balancing under all wireless network scenarios.

Wherein, which can be arbitrarily arranged.
If step 203, the judging result indicate the cell-of-origin load be more than the pre-determined threshold, obtain described in
The network coverage mode of cell-of-origin.
In embodiments of the present invention, the network coverage mode of cell-of-origin includes Multilayer Network covering and monolayer net covering.Wherein
The network coverage mode can be obtained by modes such as user's measurements.
If step 204, the network coverage mode indicate that the cell-of-origin is monolayer net overlay area, using with frequency

Specifically, here, selecting the neighboring community of suitable (such as signal quality is good, load is low) for cell-of-origin, adjustment is small
Handoff parameter between area pair carries out load migration.
After using the load for adjusting cell-of-origin with frequency MLB, the load of cell-of-origin can be obtained at predetermined intervals.
If the load in the cell-of-origin that some sampling time obtains is less than or equal to pre-determined threshold, return to step 201.If adopted at this
In certain time after the sample time, the load of the cell-of-origin of acquisition can then be recognized both less than or equal to the pre-determined threshold
To meet parameters back condition, then retract with the CIO (Cell individual offset, the offset of cell individual character) of frequency MLB.If
Load in the cell-of-origin that the sampling time obtains is more than pre-determined threshold and the state continue for the regular hour, then needs to enable and gather around

After having executed LB functions, here, the load of cell-of-origin can be still obtained according to certain period, to determine LB functions
Whether come into force.Wherein, which can be arbitrarily arranged.
Step 303 judges whether LB functions come into force.
Since first sampling time, if the first sampling time obtain the cell-of-origin load be more than it is described pre-
Gating limits, and thens follow the steps 304；If the load in the cell-of-origin that the first sampling time obtained is less than or equal to described default
Thresholding then illustrates that LB functions come into force, return to step 201.
Step 304, since first sampling time, if the first sampling time obtain the cell-of-origin load it is big
In the pre-determined threshold, then the time for being more than the pre-determined threshold to the load of the cell-of-origin carries out timing, when obtaining first
Between.
After having executed LB functions, judge to obtain since first sampling time when starting the load for obtaining cell-of-origin
Cell-of-origin load and pre-determined threshold relationship.If some first sampling time obtain cell-of-origin load be less than or
Equal to pre-determined threshold, then it represents that LB functions come into force.Otherwise, start timer and start timing, wherein the timer is for recording source
The based model for load duration of cell is higher than the time of pre-determined threshold.Assuming that in some sampling time after first sampling time, obtain
Cell-of-origin load be less than or equal to pre-determined threshold, then timer stop timing；Otherwise continue timing.
For the time value that timer obtains, it is referred to as at the first time.When first sampling time was any one sampling
Between.
If step 305, the first time are more than the first preset value and the cell-of-origin load described in the continuous N sampling time

Specifically, when adjusting the load of cell-of-origin using alien frequencies MLB, suitable neighboring community is selected, adjusts cell pair
Between handoff parameter, carry out load migration.
After having executed alien frequencies MLB functions, here, the load of cell-of-origin can be still obtained according to certain period, with determination
Whether alien frequencies MLB functions come into force.Detailed process is as follows：
Step 307, the load that the cell-of-origin is obtained according to scheduled second time interval.
Wherein, which can be arbitrarily arranged, can be identical as above-mentioned first time interval, also can be different.
Step 308 judges whether alien frequencies MLB functions come into force.
Since first sampling time, if the second sampling time obtain the cell-of-origin load be more than it is described pre-
Gating limits, and thens follow the steps 309；If the load in the cell-of-origin that the first sampling time obtained is less than or equal to described default
Thresholding then illustrates that alien frequencies MLB functions come into force, return to step 201.
Step 309, since first sampling time, if the second sampling time obtain the cell-of-origin load it is big
In the pre-determined threshold, then the time for being more than the pre-determined threshold to the load of the cell-of-origin carries out timing, when obtaining second
Between.
After having executed alien frequencies MLB functions, sentence since first sampling time when starting the load for obtaining cell-of-origin

In certain time afterwards, the load of the cell-of-origin of acquisition is both less than or equal to the pre-determined threshold, then it is believed that meeting ginseng
Number fallback conditions, the CIO of rollback alien frequencies MLB.
If step 310, second time are more than the second preset value and can not choose suitable adjacent area, if described
Second time be more than the second preset value and the decline degree of cell-of-origin load described in continuous N number of sampling time all cannot be satisfied it is pre-
If it is required that thening follow the steps 311；Wherein, N is natural number.
Wherein, which can be arbitrarily arranged, which can also be arbitrarily arranged.For example, the preset requirement
Could be provided as cell-of-origin load decrease beyond 20% etc..Suitable adjacent area, such as can be that signal quality is good, load is low
Cell.
Step 311, the load that the cell-of-origin is adjusted using same frequency MLB functions.
Specifically, in this step, selecting suitable neighboring community, the handoff parameter between cell pair is adjusted, is loaded

After performing same frequency MLB, the load of cell-of-origin can be still obtained at predetermined intervals.If in some sampling
The load for the cell-of-origin that time obtains is less than or equal to pre-determined threshold, then return to step 201.If after the sampling time
In certain time, the load of the cell-of-origin of acquisition then returns it is believed that meeting parameter both less than or equal to the pre-determined threshold
Move back condition, the CIO for the same frequency MLB that first retracts, then the alien frequencies MLB that retracts CIO.If the load in the cell-of-origin that the sampling time obtains
The regular hour is continue for more than pre-determined threshold and the state, then needs the load for enabling congestion mechanism adjustment cell-of-origin.
It as seen from the above, in embodiments of the present invention, can be small according to source when the load of cell-of-origin is more than pre-determined threshold
The network mode in area is using MLB functions or using the load of LB and MLB orthofunctions adjustment cell-of-origin, to coordinate using more
