Embodiment two：
Fig. 2 is step S19 in embodiment one, and information is directly transmitted to the energy consumption of the second terminal in the first terminal
It is that the first terminal and second terminal distribute Local resource, so that described first is whole during less than the special ratios for forwarding energy consumption
Flow chart is realized in end by the Local resource distributed with the specific steps that the second terminal directly communicates, and details are as follows：
Step S191, a Local resource in Local resource is chosen.
In the step, Local resource divides in advance.Assuming that a total of X available resources, then draw all resources
It is divided into Local resource and global resource, can is the resource number divided to distinguish each resource.Assuming that Local resource number is
1~M, then the number of global resource be M+1 to X, wherein, M, X are positive integer.The value size of M can be according to the transmitting of base station
Power is adjusted：Base station transmitting power is bigger, and the setting of M values is bigger, conversely, the setting of M values is smaller.This is because the transmitting of base station
Power is bigger, and the coverage area of base station is also bigger, and terminal can be distributed in more wide range and communicate, and between terminal-pair
The possibility of interference is also smaller, therefore more resources can be divided into Local resource and be used to supply more terminal-pairs,
With maximum resource benefit.
In this step, can Local resource be selected from small to large by number.
Step S192, judge whether the Local resource chosen has distributed to other-end using terminal.
In the step, judge whether the Local resource chosen has distributed by searching for the usage record for the resource chosen
To other-end.Wherein, the usage record of resource is used to record the service condition of Local resource, for example, in a Local resource
After distributing to a terminal-pair use, resource usage record corresponding with the Local resource will be updated to 1；Conversely, if resource is
It is released, is then somebody's turn to do resource usage record corresponding with the part resource and will be updated to 0.
If Local resource step S193, chosen is not allocated to other-end use, the Local resource that will directly choose
Distribute to the first terminal and the second terminal.
If Local resource step S194, chosen has distributed to other-end use, first terminal and second is calculated eventually
Hold the communication radius of this terminal-pair and calculate respectively it is all distributed it is described choose it is logical between the terminal-pair of Local resource
Believe radius.
Further, the communication radius of above-described embodiment multiplying for the distance between two terminals and preset authority credentials
Product.Wherein, preset authority credentials is related to terminal power, and when power is bigger, preset authority credentials is bigger, conversely, smaller.
Preferably, calculate the communication radius of first terminal and second terminal this terminal-pair and calculate respectively it is all
Before the communication radius between the terminal-pair of Local resource is chosen described in distribution, judge that the terminal log that Local resource is distributed to is
No has been more than preset maximum using number, if so, another Local resource is chosen, if it is not, the communication of computing terminal pair half again
Diameter.In the step, a maximum is set using number for each Local resource in advance, certainly, each Local resource setting is most
It can be the same or different using number greatly.The reason of setting maximum uses number is as follows：(1) when Local resource has been distributed to
It has been assigned with if too many terminal-pair in use, it is also desirable that the Local resource is distributed to other-end pair, needs to calculate respectively
Whether each pair of terminal of the Local resource can be with new terminal to generating interference, and too big so as to cause calculation amount, distribution time is too long；
(2) since Local resource has distributed to too many terminal-pair, so when the Local resource is distributed to new access terminal, new access is eventually
The possibility of existing some terminal-pair generation interference is very big in end pair and Local resource, once new terminal pair and some terminal-pair meeting
Interference is generated, new access terminal pair can be distributed to again with Local resource by finding again, and whether equally also to recalculate can produce
Raw interference, causes distribution time too long.
Step S195, judge to choose part described in the first terminal and this terminal-pair of second terminal and any distributed
Whether the distance of the terminal-pair of resource is more than the communication radius of the first terminal and second terminal this terminal-pair and described
One has distributed the sum of described communication radius chosen between the terminal-pair of Local resource.
In the step, the distance between two terminals calculate in the following manner：
In the step, the terminal-pair of Local resource is chosen to have y pairs if having distributed, need to calculate first terminal and respectively
This terminal-pair of two terminals is with other y to the distance of terminal-pair.
Further, the distance of first terminal and this terminal-pair of second terminal and another terminal-pair for first terminal and
The distance between the midpoint of second terminal and the midpoint of another terminal-pair.
The distance between two terminal-pairs calculate in the following manner：
The calculation of the communication radius of terminal-pair is as follows：
Assuming that the distance of two terminals is calculated as D in terminal-pair ii, then the communication radius of terminal-pair i is Ei=μ Di, μ is big
In 1 value, and μ and DiIt is unrelated, it is related with the transmission power of terminal.
Assuming that distributed 4 terminal-pairs that have for choosing resource, first terminal and second terminal this terminal-pair are with having distributed
The distance for choosing 4 terminal-pairs of Local resource is respectively Di,Di+1,Di+2,Di+3, first terminal and second terminal this terminal
To communication radius be Ej, the communication radius for having distributed 4 terminal-pairs for choosing Local resource is respectively Ej+1,Ej+2,Ej+3,
Ej+4, then judge DiWhether E is more thanj+Ej+1, judge Di+1Whether E is more thanj+Ej+2, judge Di+2Whether E is more thanj+Ej+3, judge Di+3
Whether E is more thanj+Ej+4。
Step S196, local money is being chosen described in the first terminal and this terminal-pair of second terminal and any distributed
The distance of the terminal-pair in source is more than the communication radius of the first terminal and second terminal this terminal-pair and any has divided with described
During with the sum of communication radius between the terminal-pair for choosing Local resource, the Local resource chosen is distributed to first
Terminal and second terminal.
If being less than or equal to, return to step S191.
In the step, Local resource is chosen when judging that first terminal and this terminal-pair of second terminal have been distributed with other
Terminal-pair generate interference when, reselect other Local resources.
In embodiments of the present invention, for a new terminal to distributing some Local resource when, judge the new terminal pair with
The other-end of some Local resource is distributed to whether generating interference, when meeting above-mentioned requirements, be the new terminal to distribution
Some Local resource.
