In order to embody the advantage of multi-service resource dispatching method provided in an embodiment of the present invention, to take priority be 1, preferential
The business that grade is 2 and priority is 3 is calculated with the maximum throughput quantity algorithm, proportional fair algorithm, round robin schedule for not dividing priority
Method and maximum weighted time delay Priority-driven Scheduling Algorithm are emulated；
As shown in figure 5, emulating with the increase of number of users to handling capacity, simulation result takes five average values；
As shown in fig. 6, emulating with the increase of number of users to average delay, simulation result is taken five times and is averaged
Value；
As shown in fig. 7, emulating with the increase of number of users to average packet loss ratio, simulation result is taken five times and is put down
Mean value；
As shown in figure 8, emulating with the increase of number of users to fair sex index, simulation result is taken five times and is put down
Mean value；
It should be noted that Fig. 5 is into Fig. 8, the curve that priority 1, priority are 2 and priority is 3 represent with
The increase of number of users, the result that use priority is presented by the user for the business that 1, priority is 2 and priority is 3；Most
Big throughput algorithm, proportional fair algorithm, round robin schedule algorithm and maximum weighted time delay Priority-driven Scheduling Algorithm curve represent with
The increase of number of users, in the case where not distinguishing priority, result that all users are emulated.

Quantity algorithm is spat, is in and the much the same level of maximum weighted time delay Priority-driven Scheduling Algorithm；In terms of average delay, priority 2
User decrease but still better than maximum weighted time delay Priority-driven Scheduling Algorithm；In terms of average packet loss ratio and fair sex index,
It is also acceptable that the user that priority is 2, which is declined,.For this kind of users, we can be applied in electric power channel radio
It is not very high business, such as video monitoring category information that some handling capacities and average delay requirement are dispatched in letter system.
The user for being 3 to priority, performance are decreased obviously, especially on average delay and fair sex index.It is main
The reason is that the resource block to priority for 3 user is limited in order to ensure that priority is the service quality of 1 user,
To guarantee to guarantee there are enough resource blocks to distribute to preferentially when load increases generation congestion in electric power wireless communication system
