Fig. 5 is that the embodiment of the present invention carries out the schematic flow sheet of Energy Saving Control to community, and as shown in Figure 5, the present embodiment carries out Energy Saving Control mainly through following steps to community:
Step 501: read the business statistics data of network management system Zhong Ge community and the measurement report data of each community user;
The discovery device of the community of the present embodiment carries out data interaction by data interaction interface and network management system, the business statistics information that reading network management system is uploaded and user's measurement report.
Step 502: judge to treat whether the first energy-conservation community exists the adjacent area of the business can bearing its overlay area;
In the present embodiment, judge whether the first community exists the adjacent area of the business can bearing its overlay area by calculating the first community with the overlapping coverage of adjacent area.
First according to the measurement report data of each community user obtained in step 501, determine the signal strength signal intensity of whole adjacent areas that diverse location point user receives in the first community, the first cell signal strength neighboring area signal intensity received with user respectively contrasts, if neighboring area signal intensity reaches predetermined condition, then can assert that this test point can be covered by adjacent area in the first community, namely at this, test point first community is overlapping with adjacent area covers; Due to user's random distribution in the first community, therefore can by the measurement report analysis of the test point of some, in the approximate overlay area thought to the first community, whole location points has all carried out overlapping Covering judgment; When if the ratio that overlapping coverage test point accounts for whole test point exceedes predetermined ratio, namely the first community is greater than predetermined value with the overlapping coverage of adjacent area, then can assert that adjacent area and the first little area overlapping cover, the business of the first cell coverage area can be born in adjacent area.
Wherein, predetermined condition can not be weaker than the first cell signal strength for neighboring area signal intensity, or neighboring area signal intensity is not weaker than the difference of the first cell signal strength and predetermined judgement threshold.Be that neighboring area signal intensity is not weaker than the difference of the first cell signal strength and predetermined judgement threshold for example below with predetermined condition, the method for the overlapping coverage of the calculating of the present embodiment described in detail:
Be prepare to carry out the first community of Energy Saving Control for Fig. 6, a district, a district has m adjacent area, and in overlay area, a district, each location point a district signal strength signal intensity is T
a, in overlay area, a district, each location point neighboring area signal intensity is T
x, predetermined judgement threshold is that t (requires T
a-t is not less than T
threshold, T
thresholdbe a predetermined value being not less than 0), then obtain the overlapping coverage P of adjacent area x at each location point in overlay area, a district by signal strength signal intensity contrast
axy:
Overlay area, a district is subdivided into n point, then the overlapping coverage P of adjacent area x in a district
axobtain by following formulae discovery:
As overlapping coverage P
axwhen being greater than predetermined value, then can assert that adjacent area x and the first little area overlapping cover, adjacent area x can bear the business of the first cell coverage area.
The Maximum overlap coverage P of a district and m adjacent area is:
P＝max{P
a1.....P
am}
Step 503: judge that can the user of the first community be switched to the adjacent area can bearing its overlay area business;
In order to guarantee the communication quality of user further, after determining that the business of the first cell coverage area can be born in adjacent area, the user also needing to judge the first community whether can successful switch to adjacent area, namely determine the cooperation relation of minizone.History service Statistical Information Analysis first community that specifically can obtain according to step 501 and each overlapping history switching times and success rate covering adjacent area, if when user all exceedes each self-corresponding predetermined threshold from the first cell merge to the switching times of an adjacent area and success rate, then assert that this adjacent area and the first community possess cooperation relation, the user of the first community can be switched to this adjacent area.
Further, can also determine whether adjacent area and the first community possess cooperation relation according to network management configuration, such as the first community has higher priority, even if then adjacent area x and the first little area overlapping cover, user can not from the first cell merge to adjacent area x; If moreover adjacent area x has special purposes, do not accept user and switch, even if then adjacent area x and the first little area overlapping cover, user can not from the first cell merge to adjacent area x.
Step 504: determine the cooperation period can closing described first community;
After the covering relation determining the first community and adjacent area and cooperation relation, also will determine the cooperation period can closing the first community further.The user of the first community determining that the business of the first cell coverage area can be born in an adjacent area and after can switch to this adjacent area, according to history service data, add up the historical traffic of this adjacent area and the historical traffic sum of the first community at times, determine the cooperation period that the historical traffic sum of the available traffic peak being less than or equal to this adjacent area is corresponding, within the cooperation period, described first community can be closed, the user of the first community is switched to this adjacent area.
Particularly, as shown in Figure 6, a district has m adjacent area, determine that a district has p adjacent area and can bear the business of overlay area, a district and the user in a district can switch to these adjacent areas through step 502-503, for each community in this p adjacent area, the history service statistics that can obtain according to step 501, determine a district and the distribution curve of each cell history traffic carrying capacity 24 hours every days, day part a district and the historical traffic sum of each community and the capacity at full capacity of respective cell are compared, calculate a district and each cell history traffic carrying capacity and the period overall length T lower than respective cell capacity at full capacity.
Such as, one day is divided into q period, Q
xfor the per period historical traffic in community, when a district and x district historical traffic and lower than x district at full capacity capacity time, t
xbe 1, otherwise t
xbe 0,
Then the cooperation period sum T in x district is:
If there is the non-vanishing community of T in this p adjacent area, then determine that a district is the community can carrying out Energy Saving Control, community can be shunted as it in the adjacent area that T is greater than 0, there is two or more T when being greater than the adjacent area of 0 in a district, and preferred T shunts community as it at maximum adjacent area.
Step 505: by the cell information report energy-saving control device of data interaction interface by the first community, makes described energy-saving control device can perform Energy Saving Control to described first community;
Wherein, energy-saving control device can be deployed in network management system, and the cell information of the first community includes but not limited to: can as the cooperation period of the adjacent area of the shunting community of the first community and correspondence thereof.The cooperation period corresponding in shunting community, after the cell information receiving the first community, is closed the first community by energy-saving control device, and the user of the first community is switched to shunting community.
Step 506: when the traffic carrying capacity shunting community rises to threshold value, energy-saving control device wakes the first community up and shares business.
The discovery device of community reads the traffic carrying capacity situation of change of shunting community by the timing of data interaction interface, when shunting notice energy-saving control device when cell business volume rises to predetermined threshold value, energy-saving control device will wake the first community up, exit power save mode, start to share business.
The embodiment of the present invention by comprehensively analyzing minizone covering relation, cooperation relation determines to bear the adjacent area for the treatment of overlay area, energy-saving cell business, and obtain the shunting community for the treatment of energy-saving cell according to piecewise analysis during cooperation, treat energy-saving cell in the cooperation period and carry out closing realizing energy-conservation.Like this in closedown behind energy-saving cell, the business of its overlay area still can be shunted community by it and bear, even if there is burst service, burst service still temporarily by the little area carrier of shunting, can avoid treating that the impact on network quality is closed in energy-saving cell; In addition, owing to treating that the business of overlay area, energy-saving cell can be born by shunting community, therefore closedown until energy-saving cell time, treat that the business carrier frequency of energy-saving cell and broadcast carrier frequency all can turn off, thus improve energy-saving effect further.
