The PRB utilization rates 12% that the load of second base station includes are less than the wealthy value 20% of default 2nd PRB utilization rates that default second load-threshold includes, the cpu busy percentage 6% that the load of second base station includes is less than the wealthy value 20% of default second cpu busy percentage that default second load-threshold includes, the UE for the base station of access second that the load of second base station includes number 5 is less than default second number 25 that default second load-threshold includes, thus may determine that the load of the second base station is less than default second load-threshold.
If the load of first base station is less than default first load-threshold, and the load of the second base station is less than default second load-threshold, then the frequency that the frequency and the second base station that the acquisition of handover module 102 first base station is supported are supported；
Specifically, handover module 102 obtains the frequency that first base station is supported, and sends the second request message to the second base station by the X2 interfaces of first base station；Second base station receives the second request message by the X2 interface of itself, obtain the frequency itself supported, the second response message is generated, the second response message carries the frequency that the second base station is supported, the second base station sends the second response message to handover module 102 by the X2 interface of itself;Handover module 102 receives the second response message by the X2 interface of first base station, disappears from the second response The frequency of the second base station support is extracted in breath.
Handover module 102 includes request unit and reduction unit.
Request unit, if different from the frequency that the second base station is supported for the frequency that first base station is supported, the UE of request access first base station is switched on the second base station；Or,

Referring to Fig. 3, this method flow includes：
Step 301:The load of first base station and the load of the second base station are obtained, the overlay area of the second base station includes the overlay area of first base station；
Specifically, when the daily low traffic period starts, first base station obtains the load of itself, and the load of the base station and the base station of overlay area of the overlay area including first base station is obtained, the low traffic period is that the load of first base station in one day is less than the period for presetting the 4th load-threshold；If the base station is a base station, the base station is defined as the second base station and the load of the base station is defined as to the load of the second base station；If the base station is multiple base stations, the minimum base station of selection load, is defined as the second base station by the base station of selection and the load of the base station of selection is defined as to the load of the second base station from the base station.
Preferably, the load of the base station of overlay area of the overlay area including first base station is obtained, including：First base station includes first base station by X2 interface the first request message of transmission of itself to overlay area Overlay area base station；The base station receives the first request message by the X2 interface of itself, obtains the load of itself, generates the first response message, and the first response message carries the load of the base station, and the first response message is sent to first base station by the X2 interface of itself；First base station receives the first response message by the X2 interface of itself, and the load of the base station is extracted from the first response message.
Wherein, the load of first base station includes the UE of PRB utilization rates, the cpu busy percentage of first base station and the access first base station of first base station number；The load of second base station includes the PRB utilization rates of the second base station, the UE of the second base station of the cpu busy percentage of the second base station and access number.The load of technical staff counted first base station in one day in advance each period, finds out load less than the default 4th load-threshold corresponding period, using the period as first base station the low traffic period.
Default 4th load-threshold includes the wealthy value of default 4th PRB utilization rates, the wealthy value of default 4th cpu busy percentage and default 4th number.
If the PRB utilization rates of first base station are less than the default 4th wealthy value of PRB utilization rates preset the 4th load-threshold and included, the cpu busy percentage of first base station includes less than default 4th load-threshold the default 4th wealthy value of cpu busy percentage and the UE of access first base station number, which are less than, presets default 4th number that the 4th load-threshold includes, it is determined that the load of first base station, which is less than, presets the 4th load-threshold；Otherwise, it determines the load of first base station is more than or equal to default 4th load-threshold.
For example, it is assumed that the low traffic period of first base station is daily 0:00 to 8:00, daily 0:When 00, the load of first base station and the load of the second base station are obtained.
Assuming that it is 9% and the UE of access first base station number is 3 that the PRB utilization rates that include of load of the first base station obtained, which are 10%, cpu busy percentage,;The PRB utilization rates that the load of second base station includes are that 12%, cpu busy percentage is 6% and the UE of the second base station of access number is 5.
Step 302:If the load of first base station is less than default first load-threshold and the load of the second base station is less than default second load-threshold, the UE for accessing first base station is switched on the second base station；
Specifically, this step can be realized by following 3021 to 3025 flow, including：
3021 :Judge whether the load of first base station is less than default first load-threshold, and judge whether the load of the second base station is less than default second load-threshold；
Wherein, presetting the first load-threshold includes the wealthy value of default first PRB utilization rates, the wealthy value of default first CPU utilization rates and default first number；Default second load-threshold includes the wealthy value of default 2nd PRB utilization rates, the wealthy value of default second cpu busy percentage and default second number.
If the PRB utilization rates of first base station are less than the default first wealthy value of PRB utilization rates preset the first load-threshold and included, the cpu busy percentage of first base station and are less than default first load-threshold includes default first The UE of the wealthy value of cpu busy percentage and access first base station number is less than default first number that default first load-threshold includes, then determine that the load of first base station is less than default first load-threshold, otherwise, it determines the load of first base station is more than or equal to default second load-threshold.
If the PRB utilization rates of the second base station are less than the default 2nd wealthy value of PRB utilization rates preset the second load-threshold and included, the cpu busy percentage of the second base station includes less than default second load-threshold the default wealthy value of second cpu busy percentage and the UE of the second base station of access number, which are less than, presets default second number that the second load-threshold includes, then determine that the load of the second base station is less than default second load-threshold, otherwise, it determines the load of the second base station is more than or equal to default second load-threshold.
For example, it is assumed that the first wealthy value of PRB utilization rates of presetting that default first load-threshold includes is that 20%, the default wealthy value of first cpu busy percentage is 15% and default first number is 20;The default 2nd wealthy value of PRB utilization rates that default second load-threshold includes is that 20%, the default wealthy value of second cpu busy percentage is 20% and default second number is 25;
It can draw, the PRB utilization rates 10% that the load of first base station includes are less than the wealthy value 20% of default first PRB utilization rates that default first load-threshold includes, the cpu busy percentage 9% that the load of first base station includes is less than the wealthy value 15% of default first cpu busy percentage that default first load-threshold includes, the UE for the access first base station that the load of first base station includes number 3 is less than default first number 20 that default first load-threshold includes, thus may determine that the load of first base station is less than default first load-threshold；
The PRB utilization rates 12% that the load of second base station includes are less than the wealthy value 20% of default 2nd PRB utilization rates that default second load-threshold includes, the cpu busy percentage 6% that the load of second base station includes is less than the wealthy value 20% of default second cpu busy percentage that default second load-threshold includes, the UE for the base station of access second that the load of second base station includes number 5 is less than default second number 25 that default second load-threshold includes, thus may determine that the load of the second base station is less than default second load-threshold.
3022:If the load of first base station is less than default first load-threshold, and the load of the second base station is less than default second load-threshold, then the frequency that the frequency and the second base station that acquisition first base station is supported are supported；Specifically, first base station obtains the frequency of itself support, and sends the second request message to the second base station by the X2 interface of itself；Second base station receives the second request message by the X2 interface of itself, obtains the frequency of itself support, generates the second response message, and the second response message carries the frequency that the second base station is supported, the second response message is sent to first base station by the X2 interface of itself；First base station extracts the frequency of the second base station support by the response message of X2 interfaces second of itself from the second response message.
3023:Judge whether the frequency supported the second base station is identical with the frequency that first base station is supported, if identical, performs step 3024;If it is different, performing step 3025; 3024:The transmission power of first base station is gradually reduced, the UE of access first base station is independently switched to the second base station, untill accessing when the UE of first base station is all switched on the second base station；
Wherein, gradually reduced with the transmission power of first base station, the coverage of its signal is also gradually decreased, access the signal of UE periodically each base stations of its present position of monitoring covering of first base station, UE can access the best base station of signal.When the signal of the UE for the accessing first base station first base stations monitored is less than the signal of the second base station, the connection that the UE is actively set up between the second base station, and the connection between first base station is disconnected, it is switched to the second base station to realize from first base station.
3025：The UE of request access first base station is switched on the second base station.
Specifically, first base station sends handover request message to the second base station, and the handover request message carries the UE of access first base station mark；Receive the switch acknowledgment message of the second base station transmission；UE of the RRC connection reconfiguration messages to access first base station is sent, the RRC connections reconfiguration message carries the mark of the second base station；UE receives the RRC connection reconfiguration messages, the mark of the second base station is extracted from the RRC connections reconfiguration message, disconnect the connection between first base station, and according to the mark of the second base station, the UE for accessing first base station, is switched on the second base station by the connection set up between the second base station with realizing.
Wherein, if the load of first base station is more than or equal to default first load-threshold or the load of the second base station is more than or equal to default second load-threshold, then wait after preset duration and being performed again since step 301, the preset duration can be 5 minutes, 10 minutes or 20 minutes etc., and the present invention is not limited to this.
Step 303:First base station is closed, so that first base station enters dormancy power save mode；
Specifically, first base station closes other functional modules in addition to CPU mini systems and X2 interface in first base station, so that other functional modules that first base station enters in dormancy power save mode, first base station in addition to CPU mini systems and X2 interface include power amplifier, D/A converter, A/D converter, DSP and FPGA etc..
First base station enters after dormancy power save mode, only CPU mini systems and X2 interface work, and other functional modules in addition to CPU mini systems and X2 interface do not work, have saved electric energy.
After first base station enters dormancy power save mode, the portfolio of second base station is possible to increase suddenly and beyond the bearing capacity of the second base station, now need activation first base station to share the portfolio that the second base station is uprushed, can specifically be realized with as follows 304 to 306 flow.
Step 304:Obtain the load of the second base station；
Specifically, first base station obtains the load of the second base station by the CPU mini systems and X2 interface of itself.When first base station enters dormancy power save mode, the CPU mini systems of first base station send the 3rd request message to the second base station by the X2 interface of first base station；Second base station is received by the X2 interface of itself 3rd request message, obtains the load of itself, generates the 3rd response message, and the 3rd response message carries the load of the second base station, and the 3rd response message is sent to first base station by the X2 interface of itself；The CPU mini systems of first base station receive the 3rd response message by the X2 interface of first base station again, and the load of the second base station is extracted from the 3rd response message.
Step 305:If the load of the second base station is more than default 3rd load-threshold, first base station is activated, first base station is entered working condition；
Specifically, the CPU mini systems of first base station judge whether the load of the second base station is more than default 3rd load-threshold, if it is, activation first base station.
Wherein, presetting the 3rd load-threshold includes the wealthy value of default 3rd PRB utilization rates, the wealthy value of default 3rd CPU utilization rates and default 3rd number.
If the number that the PRB utilization rates of the second base station are more than or equal to the UE that the default 3rd wealthy value of PRB utilization rates preset the 3rd load-threshold and included, the cpu busy percentage of the second base station are more than or equal to the second base station of the default 3rd wealthy value of cpu busy percentage or access that default 3rd load-threshold includes is more than or equal to default 3rd number that default 3rd load-threshold includes, then determine that the load of the second base station is more than or equal to default 3rd load-threshold, the functional module being turned off in first base station is opened, first base station is entered working condition.
When first base station is in dormancy power save mode, only CPU mini systems and X2 interface normal work in first base station, other functional modules in addition to CPU mini systems and X2 interface are all closed, therefore other functional modules in first base station in addition to CPU mini systems and X2 interface are opened, first base station is entered working condition.
Wherein, if the PRB utilization rates of the second base station are less than the default 3rd wealthy value of PRB utilization rates that default 3rd load-threshold includes, the cpu busy percentage of second base station is less than the number d for presetting the 3rd wealthy value of cpu busy percentage and accessing the UE of the second base station that default 3rd load-threshold includes, default 3rd number included in default 3rd load-threshold, then determine that the load of the second base station is less than default 3rd load-threshold, wait and being performed again since step 304 after preset duration, the preset duration can be 5 minutes, 10 minutes or 20 minutes etc., the present invention is not limited to this.
For example, it is assumed that it is 27% and the UE numbers of the second base station of access are 27 that the PRB utilization rates that include of load of the second base station obtained, which are 26%, cpu busy percentage,;The default 3rd wealthy value of PRB utilization rates that default 3rd load-threshold includes is that 25%, the default 3rd wealthy value of cpu busy percentage is 25% and default 3rd number is 25;
It can draw, the PRB utilization rates 26% that the load of second base station includes are more than the wealthy value 25% of default 3rd PRB utilization rates that default 3rd load-threshold includes, the cpu busy percentage 27% that the load of second base station includes is more than the wealthy value 25% of default 3rd cpu busy percentage that default 3rd load-threshold includes, the second base station The UE of the base station of access second number 27 that includes of load be more than default 3rd number 25 that default 3rd load-threshold includes, thus may determine that the load of the second base station is more than default 3rd load-threshold, first base station is then activated, first base station is entered working condition.
