Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic flow chart of an energy-saving control method of a base station according to an embodiment of the present invention, as shown in fig. 1, and the energy-saving control method of a base station according to an embodiment of the present invention includes the following steps:
s101: and determining an alternative neighbor cell corresponding to each MR sampling point according to the measurement report MR data of the main serving cell in the preset period.
Specifically, the device determines an alternative neighbor cell corresponding to each MR sampling point according to measurement report MR data of the main serving cell in a preset period. The apparatus may be a device for controlling a base station, and is not particularly limited. The preset time period can be set independently according to actual conditions, and can be selected to be 1 to 2 points in the morning. The determination of the candidate neighbor cell may be specifically as follows:
acquiring Reference Signal Received Power (RSRP) values of neighbor cells corresponding to each MR sampling point; and taking the neighbor cell corresponding to the RSRP value larger than the preset value as the candidate neighbor cell. The preset value can be set autonomously according to actual conditions, and can be selected to be-110 dBm.
S102: acquiring a group of mutually replaceable cells corresponding to the main service cell according to all the candidate neighbor cells; and determining the target cell in the mutually substitutable cell group according to the traffic volume of the main service cell.
Specifically, the device acquires a group of mutually replaceable cells corresponding to the main service cell according to all the candidate neighbor cells; and determining the target cell in the mutually substitutable cell group according to the traffic volume of the main service cell. The traffic may include a maximum number of terminals, but is not particularly limited, for example, the maximum number of terminals that can be carried by the primary serving cell is 1000, and the target cell needs to be able to carry at least the maximum number of terminals that can be carried by the target cell is 1000.
The acquisition of the group of mutually replaceable cells may be specifically as follows:
acquiring the statistics times of each alternative neighbor cell; selecting the ith alternative neighbor cell with the largest statistics times, and calculating the iMR sampling point number containing the ith alternative neighbor cell; wherein, the initial value of i is 1; adding 1 to the value of i, and continuously executing the step of selecting the i-th alternative neighbor cell with the largest statistics number in the MR sampling point which does not contain the target alternative neighbor cell until a preset termination condition is met, and forming the mutually replaceable cell group by the N finally obtained alternative neighbor cells and the main service cell; and the target candidate neighbor cells are all candidate neighbor cells corresponding to the values from 1 to i-1. The concrete explanation is as follows:
first, define "cell group that can replace each other": if the UE originally carried on the primary serving cell can be carried by other neighboring cells after the primary serving cell is turned off, and the signal quality received by the UE carried by other neighboring cells can meet the service requirement, the "primary serving cell" and the "other neighboring cells carrying the UE thereof after the primary serving cell is turned off" can "form" a group of mutually substituted cells. The method can be expressed as follows:
primary serving cell= [ neighbor cell1, neighbor cell2, neighbor cell 3, …, neighbor cell n ]
By MR data analysis, a "group of mutually replaceable cells" within the network is quickly sought:
there are two known conditions for the current network: (1) The MR data includes RSRP measured values of the main serving cell and a plurality of neighboring cells, and when the signal strength RSRP value is greater than X dBm (the value of X may be defined manually, and in general, X in the 4G network system may be taken as a weak coverage threshold-110 dBm), the value is a threshold that can meet the service requirement of the UE. (2) According to the reselection/handover principle of the UE based on the signal intensity, after the main service cell is closed, the UE can preferentially occupy the neighbor cell with the strongest signal.
Based on the above two known conditions, the MR sampling point is used for analyzing the 'cell group which can replace each other' corresponding to the main service cell, and the specific process is as follows:
(1) And (3) setting the number of all the MR sampling points of a certain main service CELL CELL1 in a preset period to be M, setting the main service CELLs of the sampling points to be CELL1, analyzing the MR sampling point data, and obtaining neighbor CELLs LQmn (the values of M and n are integers which are arbitrarily larger than zero) of which the RSRP corresponding to each MR sampling point is larger than X dBm. The following "sample point level neighbor data" may be formed:
MR sample points 1=lq11, LQ12, LQ13, LQ14, …;
MR sample points 2=lq21, LQ22, LQ23, LQ24, …;
MR sample points 3=lq31, LQ32, LQ33, LQ34, …;
MR sample points m=lqm1, lqm2, lqm3, lqm4, …;
note that: neighboring cells corresponding to the same MR sampling point are different; the neighboring cells corresponding to different MR sampling points may be the same, i.e., LQmn and LQ (m+x) (n+y) may be the same cell or different cells. Wherein x is an integer of 1 or more, and y is an integer of 1 or more.
(2) The statistical calculation is performed on the part on the right side of the equal sign of the expression of the sampling point level neighbor data in the following manner:
in LQmn, counting and calculating the neighbor cell with the largest occurrence number, and setting the neighbor cell as L11; calculating the number of first MR sampling points including the neighbor cell L11, and setting the number as N top1 The method comprises the steps of carrying out a first treatment on the surface of the At the same time, L11 and N top1 And establishing a mapping relation.
In the MR sample points that do not contain the neighbor cell L11, the calculation is performed again: the neighbor cell with the largest occurrence number is set as L12; calculating the number of MR sampling points including the neighbor cell L12, and setting the number as N top2 The method comprises the steps of carrying out a first treatment on the surface of the At the same time, L12 and N top2 And establishing a mapping relation.
In the MR sampling points that do not contain the neighbor cells L11, L12, the calculation is performed again: the neighbor cell with the largest occurrence number is set as L13; calculating the number of MR sampling points including the neighbor cell L13, and setting the number as N top3 The method comprises the steps of carrying out a first treatment on the surface of the At the same time, L13 and N top3 And establishing a mapping relation.
And the like, N times of statistical calculation can obtain neighbor cells L1N and N topN Is a mapping relation of (a) to (b).
When the following condition is satisfied, the calculation ends.
Wherein N is topi For the iMR sample point number, N is
When the number of the candidate neighbor cells, M is the number of the MR sampling points, Y is a preset expected substitution rate, and represents the service ratio which can be carried by the neighbor cells after the main service cell is closed, and the service ratio can be set autonomously, and can be selected to be 99%.
It should be noted that: because the number of neighbor cells of the main serving cell is limited, a value Z can be defined to achieve rapid convergence, and when N is greater than or equal to Z, the above condition cannot be met, the main serving cell is considered to have no substitution, and the calculation can be ended.
Through the above process, in the case of meeting the above conditions, the method is carried out according to L1N and N topN Can obtain CELL1 and its corresponding "CELL group capable of replacing each other":
CELL1＝[L11，L12，L13，…，L1N]
similarly, the above calculation can be performed on all cells in a certain area to obtain all "cell groups that can replace each other":
CELL1＝[L11，L12，L13，…，L1N]
CELL2＝[L21，L22，L23，…，L2N]
CELL3＝[L31，L32，L33，…，L3N]
CELLn＝[Ln1，Ln2，Ln3，…，LnN]
where neighbor cells on the right side of the expression on different rows allow the same, e.g. L11 and L32 are likely to be the same neighbor cells.
S103: if the main service cell is judged to meet the preset condition, the target cell is used for replacing the main service cell, and energy-saving control of a base station serving the main service cell is started.
Specifically, if the device determines that the primary service cell meets the preset condition, the device replaces the primary service cell with the target cell, and starts energy-saving control on a base station serving the primary service cell. The target cell may include at least one alternative cell, and the specific steps of the alternative primary serving cell may be as follows:
and if the main service cell is not listed in the non-shutdown cell library in advance and the at least one alternative cell can bear the traffic, replacing the main service cell by the at least one alternative cell. The traffic may be the number of UEs, and is not particularly limited. The method may further comprise:
and if judging that all the alternative cells in the alternative cell group can not bear the traffic, listing the main service cell into the non-shutdown cell library. The traffic cannot be carried for all alternative cells, as exemplified below: for example, a certain primary serving cell a has a total of three alternative cells, none of which as a whole can carry the traffic of the primary serving cell a.
The method may further comprise: the primary serving cell is listed in a library of off-state cells while the primary serving cell is replaced with the at least one alternative cell, and the at least one alternative cell is listed in the library of non-off-state cells.
The energy-saving control of the base station serving the main service cell is started in the following manner:
the device issues an instruction to a cell base station in a 'turn-off cell library', the cell base station turns on an energy-saving switch, a network side issues a reselection/switching instruction to the cell base station, a user is migrated to a corresponding alternative cell, and then the cell enters an energy-saving mode. The energy-saving mode comprises cell shutdown, cell dormancy and the existing intelligent shutdown energy-saving technology, such as base station radio frequency intelligent shutdown, carrier frequency intelligent shutdown, PSU intelligent shutdown, channel intelligent shutdown, symbol intelligent shutdown, MBSFN subframe adjustment shutdown and the like.
The load of the substituted cell can be monitored, if the sudden increase phenomenon of the traffic is found, the cell which has entered the energy-saving mode is restored to the normal working state, namely: and removing the cell from the cell library which can be turned off, and re-listing the cell into the cell library which cannot be turned off.
Fig. 2 is a flow chart of an energy saving control method of a base station according to another embodiment of the present invention, as shown in fig. 2:
step 1: it is determined whether the cell CELLn has been listed in the non-shutdown cell library. If not, executing step 2, otherwise ending.
Step 2: based on the traffic of the cell CELLn, it is determined whether the corresponding substitute cell can carry its traffic if the CELLn cell is turned off. If the load can be carried, executing the step 3; if not, step 4 is performed.
Step 3: CELLn is listed in the shutdown-capable cell library, and its corresponding replacement cells LN1, LN2, LN3, …, LNn are listed in the non-shutdown-capable cell library.
Step 4: CELLn is listed in the non-shutdown cell library.
Through the above process, the set of the turn-off cells in a certain area in the preset time period can be output, and the expression is as follows:
a preset period of time: [ Can shut down cell library ]
The following illustrates the implementation of the embodiments of the present invention by way of more illustrative examples:
a certain area is distributed with 3 macro station CELLs CELLA, CELLB, CELLC and 1 micro station CELL1. Based on historical traffic analysis, 1 to 2 am every day, CELL1, CELLA, CELLB, CELLC traffic is low, and the energy saving algorithm can be considered for this time period.
The method comprises the following steps:
1. cell coverage overlap analysis is performed based on the MR data, outputting "group of mutually replaceable cells".
(1) The number of all MR sampling points in the CELL CELL1 in the time period is 1000, the main service CELLs of the sampling points are CELL1, and the MR sampling point data are analyzed to obtain neighbor CELLs with RSRP (reactive power reduction) corresponding to each MR sampling point being more than X dBm (in the embodiment, X is taken as minus 110 dBm). The following "sample point level neighbor data" for CELL1 may be formed:
MR sample 1 = CELLA;
MR sample point 2 = CELLA;
MR sample 3=cella, CELLC;
MR sample 4 = null;
MR sample point 5 = CELLC;
MR sample 1000 = CELLC, CELLA;
note that: the "null" represents that the MR sample point has only the primary serving cell and no neighbor cells.
(2) The statistical calculation is performed on the portion on the right side of the equal sign of the expression "sampling point-level neighbor data" in the following manner.
Calculating the adjacent area with the largest occurrence number as CELLA; calculating the number N of MR sampling points containing neighboring cell CELLA top1 =800; at the same time, CELLA and N top1 And establishing a mapping relation.
In MR samples that do not contain neighbor CELLA, the calculation is performed again: the neighbor cell with the largest occurrence number is CELLC; calculating the number N of MR sampling points containing neighboring CELLC top2 =198; at the same time, CELLC is combined with N top2 And establishing a mapping relation.
After 2 times of statistical calculation, the following conditions are satisfied, and the calculation is finished.
(N top1 +N top2 )/M＝(800+198)/1000＝99.8％>＝Y
Wherein Y is the expected substitution rate, and the value of this time is 99%.
Through the above process, CELL1 and its corresponding "CELL group that can replace each other" can be derived:
CELL1＝[CELLA，CELLC]
similarly, CELL2 and its corresponding "group of mutually replaceable CELLs" can be obtained:
CELL2＝[CELLC]。
2. based on a machine learning algorithm, sorting the 'mutually replaceable cell groups', and listing the cells meeting the conditions into a 'turn-off cell library'.
Using a machine learning algorithm, sorting the following "groups of mutually replaceable cells" within 1 to 2 am:
CELL1＝[CELLA，CELLC]
CELL2＝[CELLC]
sorting:
sorting CELL1 and its "group of mutually replaceable CELLs": step 1, CELL1 is not listed in the non-shutdown cell library, and step 2 is executed; step 2, after CELLA and CELLC receive the workload of the CELLA and CELLC, the CELLA and CELLC can meet the capacity requirement of UE, and step 3 is executed; and step 3, the CELL1 is listed in a CELL library which can be turned off, and the corresponding substitute CELLs CELLA and CELLC are listed in a CELL library which can not be turned off.
Sorting CELL2 and its "group of mutually replaceable CELLs": step 1, CELL2 is not listed in the non-shutdown cell library, and step 2 is executed; step 2, the CELLC 2 service volume is more in the time period, if the CELLC receives the service volume, the UE capacity requirement can not be met, and the step 4 is executed; and step 4, the CELL2 is listed in the non-shutdown CELL library.
Through the process, the turn-off cell set in the area from 1 point to 2 points in the early morning can be output, and the expression is as follows:
1 to 2 am: (cell=cell1) can be turned off ]
3. And starting an energy-saving switch for a CELL of CELL1 from 1 to 2 in the morning.
