It should be noted that the execution sequence of above-mentioned steps 104 and step 106 is in no particular order, step can also be first carried out
106, then step 104 is executed, the present embodiment is not limited the execution sequence of step 104 and step 106.
Step 108, the source base station triggers load balancing.
User in this base station cell is switched in the cell of target BS by the source base station, realizes the load between base station
It is balanced.
In conclusion in the technical solution of the embodiment of the present invention, source base station sends to target BS and carries target BS
Cell high load capacity threshold value inquiry request message resource status request message, after target BS receives, in resource status
The cell high load capacity threshold information that target BS is carried in response message, feeds back to source base station.Source base station is according to target BS
Cell load and load door limits value the case where etc., judge whether to trigger the load balancing between base station, improve and bear between base station
The accuracy that lotus equilibrium judges, avoids user from continuously being switched between base station, reduces the risk of base station handover failure, together
When ensure that the continuity of customer service, lifting system handling capacity and user's perception.
Embodiment two
The load equalization method between a kind of base station provided in an embodiment of the present invention is discussed in detail.
With reference to Fig. 2, the load equalization method flow chart between a kind of base station in the embodiment of the present invention is shown.
Step 200, source base station sends resource status request message to target BS.
Wherein, source base station and target BS are that in contrast, source base station refers to that the user of this base station is intended to be switched to other bases
The base station stood, target BS refer to that the user of other base stations is switched to the base station of this base station.For example, the user of the base stations A is intended to switch
To the base stations B, then the base stations A are source base station, and the base stations B are target BS.
The resource status request message may include that the cell high load capacity threshold value inquiry request of the target BS disappears
Breath.
The effect of the cell high load capacity threshold value inquiry request message of the target BS is to inquire the cell of target BS
High load capacity threshold information.
The high load capacity threshold information may include uplink load threshold value and downlink composite threshold value.
Step 202, the source base station receives the resource status response message from the target BS.
After the target BS receives the resource status request message from source base station, institute can be fed back to the source base station
State the resource status response message of target BS.
Wherein, the resource status response message may include the cell high load capacity threshold information of the target BS.
Step 204, the source base station is according to the cell of the cell load information and the target BS of the target BS
High load capacity threshold information judges whether the loading condiction for meeting neighboring community；If satisfied, thening follow the steps 206；If not satisfied,
Then flow terminates.
The cell load information of the target BS may include that the cell uplink information on load of target BS and downlink are born
Lotus information.
It specifically can be according to the cell uplink information on load of target BS and the cell uplink high load capacity thresholding of target BS
Value information, and, the cell downlink information on load of target BS and the cell downlink high load capacity threshold information of target BS are sentenced
The disconnected loading condiction for whether meeting neighboring community.
Preferably, data can be divided into uplink and downlink according to transmission direction in base station, so, the step 204 can
Think：
The source base station is believed according to the cell uplink information on load of the target BS with cell uplink high load capacity threshold value
The downlink load information of breath or the target BS judges whether to meet adjacent small with cell downlink high load capacity threshold information
The loading condiction in area.
If the cell uplink information on load of the target BS is less than the cell uplink high load capacity threshold information, or
The downlink load information of the target BS is less than the cell downlink high load capacity threshold information, it is determined that meets neighboring community
Loading condiction.
For example, the cell uplink information on load of target BS is S1, the cell uplink high load capacity threshold value of target BS is believed
Breath is S, if S1 < S, judges the loading condiction for meeting neighboring community；Or the downlink load information X1 of target BS, target
The cell downlink high load capacity threshold information of base station is X, if X1 < X, judges the loading condiction for meeting neighboring community.
If the cell uplink information on load of the target BS is more than or equal to the cell uplink high load capacity threshold information,
And the downlink load information of the target BS is more than or equal to the cell downlink high load capacity threshold information, it is determined that discontented
The loading condiction of sufficient neighboring community.
For example, the cell uplink information on load of target BS is S2, the cell uplink high load capacity threshold value of target BS is believed
Breath is S, and the downlink load information of target BS is X2, and the cell downlink high load capacity threshold information of target BS is X, if S2 >=

The trigger condition of weighing apparatus.
For example, the cell uplink information on load of source base station is S3, the cell uplink high load capacity threshold information S ' of source base station,
The cell uplink information on load S4 of target BS, the cell uplink high load capacity threshold information S of target BS, if S3 >=S ', and
S3-S4 >=S '-S, it is determined that meet the trigger condition of load balancing.
If the cell load information of the source base station is less than the cell high load capacity threshold information of the source base station, Huo Zhesuo
The difference of the cell load information of source base station and the cell load information of the target BS is stated, the source base station is less than or equal to
The difference of cell high load capacity threshold information and the cell high load capacity threshold information of the target BS, it is determined that be unsatisfactory for bearing
The trigger condition of lotus equilibrium.
For example, the cell downlink information on load of source base station is X3, the cell downlink high load capacity threshold information X ' of source base station,
The cell downlink information on load X4 of target BS, the cell downlink high load capacity threshold information X of target BS, if X3 < X ', or
