Embodiment
, should be appreciated that following illustrated preferred embodiment only is used for explanation and explains the present invention, and be not used in qualification the present invention a preferred embodiment of the present invention will be described in detail below in conjunction with accompanying drawing.
Fig. 1 has shown the method flow signal of the shared same RRU multi-carrier power of multi-operator provided by the invention, and is as shown in Figure 1:
Step S101, the proprietary power of each operator of configuration on RRU.
Step S102, power is shared in configuration on RRU.The configuration of sharing power comprises two kinds of methods, the first, the power outside the targeted carrier's that need take shared power RRU on the proprietary power as shared power; The second, the power outside the proprietary power of each operator on the RRU as shared power.
Step S103 is that each operator's dynamic assignment is shared power according to targeted carrier's power operating position.Different according to the method for sharing power configuration, distribute the method for sharing power also different at a time under the condition of crack.
To first kind of mode, as shared power,, distribution need carry out following processing when sharing power to the power outside the proprietary power that need take the targeted carrier who shares power on the RRU:
Take priority for each operator sets, and judge the power seized that obtains the targeted carrier according to taking priority.
If the targeted carrier takies the proprietary power that power and required power sum are less than or equal to the targeted carrier, then distribute to said targeted carrier to required power.
If the targeted carrier takies power and the required power sum proprietary power greater than the targeted carrier; Then according to idle power with can seize power for the targeted carrier distributes shared power; If idle power is more than or equal to required power; Then distribute to the targeted carrier to required power; Otherwise according to idle power with can seize the power sum for the targeted carrier distributes shared power, if idle power with can seize the power sum more than or equal to required power, then basis takies priority and distributes to the targeted carrier to required power.Wherein, the power that takies the low operator's use of priority is preferentially seized.If idle power with can seize the power sum still less than required power, then do not distribute power to the targeted carrier, distribute failure.
Power takies priority and comprises that static power takies priority and dynamic power takies priority.It is preset parameters that static power takies priority, and dynamic power takies priority and is based on static power and takies that situation that priority and each operator take power calculates.When the targeted carrier takies power and does not reach its proprietary power under RRU; For the targeted carrier distributes available proprietary power; If power absorb does not promptly have idle power, then this RRU is gone up dynamic power and take the shared power division that the minimum operator of priority takies and give the targeted carrier.Dynamically taking the minimum operator of priority is to take power to take the minimum operator of priority above static power in the operator of its preset proprietary power amount.In when, power taking place seizing when, take the operator that power do not reach its proprietary power seizing of its proprietary power enjoyed limit priority, just to take priority the highest for its dynamic power.
In order to prevent to share frequent the seizing of power; Threshold frequency is set to be controlled sharing taking of power; When the idle power of RRU is increased to threshold power; Just allow to distribute shared power, when idle power reduces to or be lower than threshold power, then do not allow for the targeted carrier and distribute shared power to the targeted carrier.Wherein, threshold power can be to share the percentage that power takies, and also can be to share the actual power value that power takies.
To the second way, as shared power,, distribution need carry out following processing when sharing power to the power outside the proprietary power of each operator on the RRU:
Take priority for each operator sets, judge the power seized that obtains the targeted carrier according to taking priority.
According to the targeted carrier take power and proprietary power, calculate targeted carrier's the proprietary power of residue.
If the proprietary power of residue is then distributed to the targeted carrier to required power more than or equal to required power, otherwise according to the idle power sum of residue proprietary power and shared power for the targeted carrier distributes shared power.
If proprietary power of residue and idle power sum are more than or equal to required power; Then distribute to the targeted carrier to required power; Promptly part takies targeted carrier's the proprietary power of residue; Part takies targeted carrier's idle power, otherwise according to residue proprietary power and idle power and can seize the power sum for the targeted carrier distributes shared power.
If remain proprietary power and idle power and can seize the power sum more than or equal to required power; Then distribute to the targeted carrier to required power according to taking priority; Promptly part takies targeted carrier's the proprietary power of residue, and part takies targeted carrier's idle power, and part takies can seize power; Wherein, the power that takies the low operator's use of priority is preferentially seized.
If remain proprietary power and idle power and can seize the power sum less than required power, then do not distribute power to the targeted carrier, distribute failure.
Fig. 2 has shown the device block diagram of the shared same RRU multi-carrier power of multi-operator provided by the invention, and is as shown in Figure 2, comprises that parameter configuration unit, power take priority unit and power distributing unit.
Wherein, parameter configuration unit is each operator's parameter preset information on RRU, comprises the proprietary power and the shared power that dispose each operator, sets threshold power, and each operator initially take priority.
Power takies priority unit, is used to provide the priority that takies of each operator.According to initially the taking priority and take the priority that takies that power situation recomputates each operator of each operator, and calculate targeted carrier's the shared power that takies.
Power distributing unit is according to the power situation of parameter information in the parameter configuration unit and the distribution of each operator; Judge whether targeted carrier's power request can distribute; When underpower, judge whether to seize shared power, seized the shared power which operator takies.
Fig. 3 has shown the processing procedure signal of the shared same RRU multi-carrier power of multi-operator that first embodiment of the invention provides; Except the proprietary power of targeted carrier's configuration; Remaining power all is defined as shared power; When the power amount that under the RRU time slot, takies as the targeted carrier reaches its proprietary power amount, can be that it distributes and shares power resource.Under RRU time slot condition, control thresholding X is set, after idle power increases to control thresholding X, allow for operator and distribute shared power resource, share power resource otherwise do not allow for operator's distribution.As shown in Figure 3:
Step S301 judges that the targeted carrier has taken power and added this time need to distribute power whether to reach proprietary power amount, if, execution in step S307, otherwise, execution in step S302.
Step S302 judges whether the idle power of sharing power reaches the requirement of power demand amount, if, execution in step S306, otherwise, execution in step S303.
Step S303 finds out than targeted carrier dynamic power and takies the low operator of priority, and calculates the amount that these operators can seize power, execution in step S304.Wherein, Except that the targeted carrier, if the power that takies of other operator is less than proprietary power amount, so its to take priority the highest; If targeted carrier's the power that takies is less than proprietary power amount; But taken power and added this required power sum greater than proprietary power amount, the targeted carrier also can only seize according to preset priority so, and not promoting its priority is limit priority; If targeted carrier's the power that takies adds that the power sum that this time needs to distribute is not more than proprietary power amount, to take priority the highest for its power so.
Step S304 calculates existing idle power and adds whether can seize the power sum reaches the requirement of power demand amount, if, execution in step S305, otherwise, execution in step S308.It is exactly the shared shared power of these operators that dynamic power takies the power the seized amount that priority is lower than other operators of targeted carrier.If it is not enough to seize the power amount, just need not go to have seized the shared power of these operators, then do not distribute power to the targeted carrier.
Step S305; Taking priority by dynamic power is low to moderate dynamic power and takies the low shared shared power of operator of dynamic power priority that the priority height is robbed the accounting targeted carrier successively; Idle power just stops to seize execution in step S306 after reaching the power demand amount.Seize dynamic power at first and take the shared shared power of the minimum operator of priority; If idle power adds this preemptible and shares power less than the power demand amount; So then earlier seized the shared shared power amount of the operator of low priority; Go the next priority time low shared shared power amount of operator again, the rest may be inferred, till the power demand amount that reaches the targeted carrier, just stops to seize.If there is the dynamic power of a plurality of operators to take priority less than the N of operator, and the dynamic power of these operators takies priority and equates, the order seized of these operators is at random so.
Step S306 is for the targeted carrier distributes power demand.
Step S307 judges whether to allow the targeted carrier to distribute shared power, if idle power more than or equal to threshold power, then allows, and execution in step S302, otherwise, then do not allow execution in step S308.
Step S308 does not distribute power to the targeted carrier.
Share the processing procedure of same RRU multi-carrier power below to the multi-operator of Fig. 3, an instantiation is provided, the operating power of establishing certain RRU is 60w, and the maximum transmission power of following 6 carrier frequency of RRU is 14w.The A of operator, B, C shares power resource, 2 carrier frequency of the A of operator fixed configurations, the power of fixed allocation 20w; 2 carrier frequency of the B of operator fixed configurations, the power of fixed configurations 20w; 2 carrier frequency of the C of operator fixed configurations, the power of fixed configurations 20w; Operator's A static power takies priority and takies priority greater than operator's B static power, and operator's B static power takies priority and takies priority greater than operation C static power.
Suppose in user's distribution condition of time slot N to be that the A of operator has 2 full rate users, accounts for 14w power respectively, accounts for 28w power altogether, the B of operator has 2 full rate users, accounts for 14w power respectively, accounts for 28w altogether.This moment, idle power had 60-28-28=4w.
If this moment, the C of operator also will insert the user that initial power is 14w at time slot N.Judge at first whether the power that the shared power of the C of operator adds this sub-distribution exceeds amount, and it is 0 that the C of operator takies power, and this sub-distribution power is 14w, and proprietary power amount is 20w.So do not exceed proprietary power amount.Next judges whether idle power is enough, and this moment, idle power was 4w, and is not enough, need seize the power that other operator takies the proprietary amount of oneself.Because this moment, the proprietary power amount of the C of operator was used by other operator, so the dynamic power of C takies priority for the highest at this moment.
At first seize power and take the low B of operator of priority, the proprietary amount of the B of operator is 20w, and taking power is 28w; The preemptible amount is 8w, seizes the also power needs of the C of unmet operator of back, so will continue to seize the power of the A of operator; The proprietary amount of the A of operator is 20w, and taking power is 28w, is 8w so can take amount; The required power of seizing of single C of operator this moment is (14w-4w-8w)=2w; So only seize the power of the A2W of operator, after having seized, distribute 14W power for the C of operator.
Fig. 4 has shown the processing procedure signal of the shared same RRU multi-carrier power of multi-operator that second embodiment of the invention provides, and except the proprietary power of all operators' configurations, remaining power all is to share power.The proprietary power of operator can be not shared by other operator, so when the proprietary power of residue of certain time slot of targeted carrier under RRU can satisfy requiring of required distribution power, do not need to go to judge dump power, just directly can distribute again.When the proprietary power of targeted carrier's residue can not satisfy the amount requirement of power demand; Need judge that also the idle power of sharing power adds whether targeted carrier's the proprietary power of residue satisfies the requirement of power demand amount; If satisfy; Then can distribute power, part takies targeted carrier's proprietary power amount, and part takies shares the power amount.If do not satisfy, can remove to seize the shared shared power of low priority operator.If after seizing, residue is shared power and is added that targeted carrier's the proprietary power of residue satisfies the power demand requirement, then distributes power, otherwise, the power division failure.As shown in Figure 4:
Step S401 judges that the targeted carrier has taken power and added this time need to distribute power whether to reach its proprietary power amount, if, execution in step S402, otherwise, execution in step S406.
Step S402 judges the proprietary power of residue adds whether the idle power of sharing power satisfies the power amount requirement that these needs distribute, if, execution in step S406, otherwise execution in step S403.
Step S403 confirms to take the low operator of priority than targeted carrier power, and calculates the amount that these operators can seize power, execution in step S404.
Step S404 judges targeted carrier's available free power adds whether preemptible power satisfies these needs and distribute the requirement of power amount, if, execution in step S405, otherwise execution in step S407.Wherein, targeted carrier's available free power is meant that it remains proprietary power and adds the idle power of sharing power.
Step S405; Taking priority by dynamic power is low to moderate dynamic power and takies the low shared shared power of operator of dynamic power priority that the priority height is robbed the accounting targeted carrier successively; Targeted carrier's available free power just stops to seize execution in step S406 after reaching the power demand amount.
Step S406 is for this operator distributes power.
Step S407 distributes power for this operator.
In sum; The present invention has following technique effect: the present invention sets under RRU and shares power; And the method for salary distribution that is directed against different sharing power provides the distribution method of shared power; Realized that multi-operator in the power resource dynamic adjustable between each carrier frequency under the same RRU, has improved the utilance of power resource greatly.
Although preceding text specify the present invention, the invention is not restricted to this, those skilled in the art can carry out various modifications according to principle of the present invention.Therefore, all modifications of doing according to the principle of the invention all are to be understood that to falling into protection scope of the present invention.
