Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.
Fig. 1 is according to the flow chart of the base station power consumption control method of the embodiment of the present invention.As shown in Figure 1, comprise according to the base station power consumption control method of the embodiment of the present invention:
Step S102, divides group of base stations and the message volume threshold value of group of base stations is set, and wherein, each group of base stations comprises multiple base stations.
Step S104 chooses a center base station in above-mentioned multiple base stations, and wherein, center base station can cover the scope that in this group of base stations, all base stations cover during with maximum power transmission signal.
Step S106, center base station compares the message volume of all base stations and the size of message volume threshold value in the group of base stations under it.
Step S108, in the message volume of all base stations during lower than message volume threshold value, center base station improves current energy-conservation grade, its transmitting power promotion is arrived maximum, and terminal corresponding all base stations is all switched in center base station, turn-off the radio frequency of other base stations except center base station in all base stations.
Preferably, as shown in Figure 1, after step S106, can also comprise following processing:
Step S110, in the time that the message volume of all base stations exceedes message volume threshold value, center base station reduces current energy-conservation grade, notifies all base stations to open radio frequency, and reduces the transmitting power of center base station.
In the time of actual arranging net, frequency and the bandwidth that can use due to each operator are limited, in order to prevent co-channel interference, use the base station of identical frequency will ensure not cover the same area as far as possible.This just causes in some region, and while arranging net as the traffic carrying capacity of region, conference and exhibition center when meeting peak, base station is relatively intensive, and each base station can not be with maximum power transmission signal.Therefore, in the time of the traffic carrying capacity less (lower than preset message volume threshold value) in these regions, can increase the radio-frequency power of certain base station (being center base station), allow this base station cover larger scope, turn-off the radio frequency of all carrier frequency under this base station range simultaneously.So, under this region, only need to open the radio frequency of a base station, reduce to greatest extent power consumption.In the time that the traffic carrying capacity in this region continues increase and exceeded preset message volume threshold value, center base station needs to notify all base stations to open radio frequency, and reduce self transmitting power, to prevent interference, the concrete numerical value reducing can be selected flexibly according to factors such as the distributions of the size of traffic carrying capacity and client, can preferentially select to be down to the level before radio-frequency power does not increase.
In specific implementation process, in order to carry out smoothly the switching of group of base stations mode of operation, can be centered by operation maintenance center transmitting power under the different energy-conservation grades of base station sets (corresponding to different mode of operations).For example, group of base stations can be divided into two kinds of energy-conservation grades: not energy-conservation and maximum energy-conservation.Centered by under two kinds of energy-conservation grades, the transmitting power of base station sets is respectively P0 and PM.In the time that group of base stations is worked under not energy-conservation grade, the radio frequency of these all base stations of group of base stations is all under mode of operation, and the radio-frequency emission power of center base station is P0, and coverage is less, can prevent to disturb; And be switched to while working under maximum energy-conservation grade when group of base stations, the radio-frequency emission power of center base station is PM, now the radio frequency of this other base station of group of base stations, all under shutdown mode, covers full wafer region by center base station.
Preferably, step S106 may further include following processing: center base station receives the message volume that in the group of base stations under it, timing of all base stations reports, count the message volume of all base stations in this group of base stations, and the size of the message volume of more all base stations and message volume threshold value.
Preferably, above-mentioned message volume include but not limited to following one of at least: number of users, the channel quantity taking.
In specific implementation process, the message volume of this base station can regularly be reported in all base stations of group of base stations to center base station, and the number of channel that comprise number of users, takies etc., are responsible for gathering by center base station, and adjudicates this group of base stations and be adapted at working under which pattern.If message volume is less, center base station self just can be held these business, center base station just expands the transmitting power of oneself until can cover the full wafer region of this group, and notify all base stations of this group that the terminal in current network is switched in center base station, all turn-off radio frequency all base stations of group of base stations except center base station afterwards, to reach the object of saving the energy.When in network, number of users increases, center base station reinforms all base stations of this group and opens radio frequency, and center base station is dwindled transmitting power to not energy-conservation transmit power level, to prevent that other base station signals are caused to interference simultaneously.
Preferably, in step S102, can also, on the basis of message volume threshold value, a buffered communication traffic carrying capacity threshold value be set.So, step S108 and step S110 change into:
Step S108 ', in the message volume of all base stations during lower than the difference of message volume threshold value and buffered communication traffic carrying capacity threshold value, center base station improves current energy-conservation grade, its transmitting power promotion is arrived maximum, and terminal corresponding all base stations is all switched in center base station, turn-off the radio frequency of other base stations except center base station in all base stations.
Step S110 ', in the message volume of all base stations during higher than message volume threshold value and buffered communication traffic carrying capacity threshold value sum, center base station reduces current energy-conservation grade, and radio frequency is opened in all base stations of informing base station group, and reduces the transmitting power of center base station.
Buffered communication traffic carrying capacity threshold value is further set, can prevents the ping-pong that single thresholding causes.
Preferably, taking base station as the above-mentioned group of base stations of basic comprising unit can be in multistage group of base stations other group of base stations of lowermost level, wherein, this multistage group of base stations is corresponding to multiple energy-conservation grades, and the group of base stations at different levels in this multistage group of base stations are all using its other group of base stations of low one-level as basic comprising unit, and group of base stations at different levels all have a center base station.
In specific implementation process, can be according to the size of message volume in current network, set multiple energy-conservation grades, set up multistage group of base stations, be subdivided into multistage subgroup, every grade of subgroup resets center base station at different levels.Segmentation layer by layer accomplishes to save to greatest extent the energy.For example group of base stations is in the time of energy-conservation grade not, under all base stations are all in running order; Group of base stations is in 1 grade when energy-conservation, setting power when 1 grade of center base station expands transmitting power to 1 grade energy-conservation grade, and other base station radio-frequency turn-offs; By that analogy; Group of base stations, in the time of the energy-conservation grade of maximum, only has the power emission signal of center base station with the energy-conservation level setting of maximum, and radio frequency is all turn-offed in other all base stations of this group of base stations.
Below in conjunction with example and accompanying drawing 2 to accompanying drawing 4, above preferred embodiment is elaborated.
As shown in Figure 2, the quality of service while communicating by letter peak in order to meet, when operator arranges net in certain region, base station distribution is relatively intensive.But because the available frequency of operator is limited, in order to prevent co-channel interference, each base station can not be with maximum power transmission signal.Base station a can cover whole region during with maximum power transmission radiofrequency signal, but disturbs in order to prevent, while arranging net, just the transmitting power of base station a is narrowed down to and can only cover twill region.
When hour (lower than preset message volume threshold value) of this area business amount, the radio-frequency power of base station a can be adjusted to maximum transmission power, then the mobile terminal of all base stations under a coverage of base station is all switched to base station a upper, then the radio frequency of these base stations is turn-offed.Because base station a can cover the coverage of all these base stations, therefore this region there will not be covering blind spot.And now to only have the radio frequency of base station a be under mode of operation in this region, and the radio frequency of other base station has all turn-offed, thereby has saved to greatest extent the energy consumption of system.
In the time that the traffic carrying capacity of base station a is larger, base station a notifies other base station under its coverage to open radio frequency, and base station a narrows down to transmitting power initial setting again afterwards, avoids disturbing with other base station.
Fig. 3 is the parameter setting procedure figure of the operation maintenance center of the example according to the present invention, needs the parameter flow process of setting as follows, is illustrated as an example of the base station deployment structure shown in Fig. 2 example:
Step S302: divide into groups in the base station in certain region, and specify the center base station of each group.Taking the base station deployment structure shown in Fig. 2 as example, base station a, b, c, d, e, f, g are divided into one group, and center base station is base station a.
Step S304: the center base station of each group is set the transmitting power under different energy-conservation grades.In base station deployment structure shown in Fig. 2, this group of base stations is divided into two kinds of energy-conservation grades: not energy-conservation and maximum energy-conservation, when not energy-conservation, energy-conservation grade is minimum, maximum when energy-conservation the highest energy-conservation grade; The transmitting power of setting for base station a under two kinds of energy-conservation grades is respectively P0 and PM.In the time that group of base stations is worked under not energy-conservation grade, the radio-frequency emission power of base station a is P0, and coverage is less, can only cover twill region, and now the radio frequency of these all base stations of group of base stations is all under mode of operation; When group of base stations in the time working under the energy-conservation grade of maximum, the radio-frequency emission power of base station a is PM, and coverage is larger, can cover whole region, and now the radio frequency of this other base station of group of base stations is all under shutdown mode.
Step S306: set the message volume thresholding of each energy-conservation grade of group of base stations, comprise number of users, busy channel number etc.In the time that the message volume of group of base stations reaches the thresholding of certain energy-conservation grade, the operating state of this group base station is just switched to this energy-conservation grade.Require energy-conservation traffic carrying capacity thresholding must be less than the maximum capacity of this group switching centre base station.Multipotency as in center base station holds 300 users, and energy-conservation thresholding must be less than 300 users, otherwise in the time that this group base station enters maximum energy-conservation level model work, has certain customers and cannot access center base station and affect service quality.In order to prevent that single thresholding from causing ping-pong, buffering thresholding can be further set, as the message volume of group of base stations lower than the energy-conservation thresholding of maximum with buffering thresholding difference time, just allow to be switched to maximum energy-conservation grade; And the message volume that exits maximum energy-conservation grade must reach maximum energy-conservation thresholding with buffering thresholding with just passable.
Step S308: send the setting data of operation maintenance center to each base station, the parameter of setting to step S306 by step S302 sends to all base stations, and each group of base stations is by the parameter work according to setting.
As shown in Figure 4, group of base stations mode of operation (energy-conservation grade) switching flow is as follows:
Step S402: the current message volume in this base station is regularly reported to the center base station of this group in all base stations of group of base stations.
Step S404: center base station gathers after the message volume of these all base stations of group, the message volume thresholding of each energy-conservation grade of setting according to operation maintenance center is adjudicated.
Step S406: if court verdict is identical with the energy-conservation grade of current base station group, do not need to do any processing; If court verdict is different from the energy-conservation grade of current base station group, enter step S408.
Step S408: whether the energy-conservation grade that judges group of base stations improves.If improving, the energy-conservation grade of group of base stations enters step S410; If the energy-conservation grade of group of base stations reduces, enter step S412.
Step S410: in the time that the energy-conservation grade of group of base stations improves, center base station needs the transmitting power of this grade of first transmitting power being brought up to operation maintenance center's setting, ensures that the coverage of center base station is larger.
Step S412: center base station sends energy-conservation grade and switches instruction to all base stations of this group, wherein indicated new energy-conservation grade.Process after receiving this Indication message accordingly each base station: if energy-conservation grade improves, by the terminal force handoff of this base station to the frequency of center base station, then turn-off the radiofrequency signal of this base station, reply energy-conservation grade switching response message to center base station, because this base station is to turn-off radio frequency, there will be no terminal access, therefore can stop regularly reporting message volume; If energy-conservation grade reduces, original this base station radio frequency turn-offing is opened, then reply energy-conservation grade switching response message to center base station, continue regularly to report the message volume of this base station simultaneously.
Step S414: center base station need to be collected the energy-conservation grade switching response message that reply all base stations of neat this group.
Step S416: if the energy-conservation grade that court verdict is group of base stations in step S408 reduces, in step S412, has opened the radio frequency of shutoff all base stations of group of base stations, in order to prevent disturbing, center base station need to be reduced to transmitting power new transmitting power corresponding to energy-conservation grade.
