Difference.
In present embodiment, cellular network operator equipment and multiple target UEs can be simultaneously to NjA access equipment
Service is provided, therefore N represents the source quantity of target data, capacity V represents the access equipment sum for needing target data.I-th
Corresponding i-th of the target UE of kind of article or the available service of cellular network operator equipment, n [i] part can be with representing target
The service times that user equipment or cellular network operator equipment can provide, it is 1 that volume c [i], which characterizes access equipment, is worth w
[i] represents the inverse for the energy consumption that the service that target UE provides 1 target data by 1 access equipment is spent.Due to
Knapsack volume V is positive integer, and the volume c [i] of each product is 1, is filled so knapsack is sure.Therefore it is used in multiple target
The access equipment number summation that family equipment is serviced is equal to NjIn the case where, multiple target use can be found out when solving knapsack algorithm simultaneously
The minimum value of family equipment energy consumption.
When solving multiple knapsack algorithm, for i-th kind of article, corresponding article has n [i] part, the weight of each product
For c [i], it is worth as w [i].Therefore, there is+a kind of n [i] service for i-th kind of article, i.e., obtaining number of packages every time can be 0,
1 ..., n [i].Maximum valence when preceding i kind article has used the capacity j of knapsack just is indicated in the present invention by dp [i] [j]
Value.And when preceding i kind article being placed in tune with capacity after knapsack reaching j, there are two kinds of situations: the first situation is i-th kind of article
It is not put into knapsack, maximum value at this time is dp [i-1] [j].Second situation is that i-th kind of article has taken k part to be then placed in
In the knapsack.Maximum value at this time is dp [i-1] [j-k*c [i]]+k*w [i], (1≤k≤n [i]).The first situation is visual
For the special circumstances of second situation, i.e. i-th kind of article takes k=0 part to be put into knapsack.It therefore, can in conjunction with both the above situation
Obtain the state transition equation about dp [i] [j].Specific such as formula (1) is shown.
Dp [i] [j]=max { dp [i-1] [j-k] * c [i]+k*w [i] } | 0≤k≤n [i] (1)
On the basis of above-mentioned algorithm, present embodiment has carried out the improvement of adaptability, i.e. the value w [i] of Individual Items is right
What is answered is the inverse of the energy consumption of respective objects user equipment or cellular network operator equipment, therefore energy consumption is smaller, corresponding reciprocal
It is worth bigger.What therefore dp [i] [j] represented in formula (1) is the multiple target user equipment when the used capacity of knapsack is j
And the maximum value of cellular network operator equipment energy consumption reciprocal value.It can be more accurately to each target user using knapsack algorithm
The access equipment of equipment distribution respective numbers, it is ensured that whole transmission energy consumption expense is in relatively low level.
Since what is solved in this application using knapsack algorithm is multiple target user equipment energy consumption minimum value.Therefore it is used as one
Kind preferred embodiment, this method further comprises:
Each service for accumulating time target data is provided to access equipment by two-dimensional array corresponding record target UE
When total transmission energy consumption expense, and generating record according to two-dimensional array has each target UE respectively accumulate time total biography when servicing
The statistical form of delivery of energy consumption expense.
Present embodiment introduces aided two-dimensional array res [N] [V], characterizes total when servicing whole access equipment
Transmit the minimum value of energy consumption expense.Since dp [i] [j] is by dp [i-1] [j-k*c [i]]+k*w [i], k in (1≤k≤n [i])
Value determine that therefore when the value of k determines, the value of corresponding res [i] [j] also can determine, can specifically be asked by formula (2)
?.And the value of res [N] [V] is the minimum value of total transmission energy consumption expense.It is as follows that specific algorithm solves process.
For present embodiment by introducing 2-D data, each target UE that records that can be relatively reliable respectively accumulates time clothes
Total transmission energy consumption expense when business, and guarantee the accuracy of subsequent statistical form generated.
In addition, as a preferred embodiment, the bandwidth of unauthorized frequency range is 20MHz.
