When stating the allocation order of D2D equipment pair, the waiting time delay tolerance of the D2D equipment pair is less than to the D2D equipment of first threshold
To distribution priority be set as maximum, and determined according to the waiting time delay tolerance and data to be transmitted amount of D2D equipment pair
The distribution priority of other D2D equipment pair；
According to the distribution priority of D2D equipment pair, the allocation order of D2D equipment pair is determined.
For example, the waiting time delay tolerance of fire-alarm is less than first threshold, then it is the distribution of fire-alarm is preferential
Grade is set as maximum.Other D2D equipment according to waiting time delay tolerance and data to be transmitted amount to that will determine allocation order.
Wherein, first threshold can wait for time delay tolerance threshold value Tlim, time delay tolerance is waited for be less than threshold value Tlim's
The distribution highest priority of D2D equipment pair, for example, fire-alarm time delay tolerance very little, can be by such D2D equipment pair
Time delay tolerance be set smaller than and wait for time delay tolerance threshold value Tlim, distribute priority and be set as highest.
Optionally, the distribution priority of other D2D equipment pair is calculated according to following equation：
Wherein, UjIt is D2D equipment to DjDistribution priority；QjIt is D2D equipment to DjData to be transmitted amount；
For total transmission quantity of all D2D equipment pair；TmaxFor the time delay tolerance maximum value of setting；TjIt is D2D equipment to DjTime delay

Such as one share 3 D2D equipment pair, D2D equipment to A, D2D equipment to B and D2D equipment to C, if 3 D2D equipment
To allocation order be that D2D equipment is more than D2D equipment to B to A, be more than D2D equipment to C, be then first that D2D equipment is distributed A and provided
Source first determines whether D2D equipment then will be with D2D if more than second threshold more than second threshold to the data to be transmitted amount of A
Equipment distributes to D2D equipment to A to whole resource blocks in the resource set of blocks of the corresponding cellular terminals of A；If D2D equipment is to A's
Data to be transmitted amount be not more than second threshold, then selected in D2D equipment to the resource set of blocks of the corresponding cellular terminals of A to
A few resource block distributes non-D2D equipment to A, is D2D equipment to B according to allocation order after D2D equipment D is complete to A resource allocations
Resource is distributed, is D2D equipment to C points after D2D equipment distributes resource to B as distribution method of the method with D2D equipment to A
With resource, until all D2D equipment to all distribute resource or can not distribute resource until.If 3 D2D equipment pair
Allocation order is that D2D equipment is equal to D2D equipment to B to A, is more than D2D equipment to C, then compares D2D equipment to A and D2D equipment
It is the D2D equipment that waits for time delay tolerance high to first distributing resource to the waiting time delay tolerance of B, or is D2D equipment pair at random
A and D2D equipment distributes resource to B.
Wherein, second threshold is data to be transmitted amount threshold value QlimIf the data to be transmitted amount of the D2D equipment pair is more than threshold
Value Qlim, since the data to be transmitted amount of the D2D equipment pair is very big, so the resource needed when transmission is relatively more, then being directly should

The D2D equipment also needs to communicate to having monopolized all resources of cellular terminal, cellular terminal, then will be with the D2D equipment to corresponding
Resource set of blocks in the cellular terminals of all resource blocks be switched to WI-FI (Wireless Fidelity, wireless network) ring
Continue to communicate under border.
Data to be transmitted amount be more than second threshold D2D equipment to distributing resource after, throughput rate to be passed be not more than the second threshold
The D2D equipment of value is to then needing to select at least one resource in the resource set of blocks from the D2D equipment to corresponding cellular terminal
Block distributes to the D2D equipment pair.
Optionally, it is selected at least in the resource set of blocks from the selected D2D equipment to corresponding cellular terminal
One resource block distributes to the selected D2D equipment pair, according to the selected D2D equipment to other noisy D2D
The quantity of equipment centering target D2D equipment pair, determines resource set of blocks of the selected D2D equipment to corresponding cellular terminal
