All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a flowchart of a first embodiment of a method for scheduling wireless resources in an electrical power communication network according to an embodiment of the present application is shown.
In this embodiment, a method for scheduling wireless resources in an electric power communication network includes:
It can be understood that when the user needs the radio resource, a scheduling request is sent to the scheduler, and the scheduler acquires the real-time operation data information of the user in response to the request of the user.
And 102, configuring the weight of the real-time operation data information according to the network slice characteristics of the user.
And 103, calculating the scheduling priority of the user based on a preset scheduling priority calculation formula according to the real-time operation data information and the weight of the real-time operation data information.
It should be noted that the weight of the real-time operation data information is determined according to the characteristics of the network slice where the user is located, and it can be understood that the wireless network is regarded as a whole, the wireless network is cut into a plurality of different types of network slices, and each network slice has a plurality of users; the characteristics of the users are determined according to the characteristics of the network slices where the users are located, so that the weight of the real-time operation data information of the users is determined according to the characteristics of the network slices where the users are located, and the differentiation requirements of each user are met.
And substituting the real-time operation data information of the user and the weight of the real-time operation data information into a preset scheduling priority calculation formula to calculate the scheduling priority of the user.
And step 104, scheduling the wireless resource s in the resource block to the user based on the scheduling priority.
The number of the wireless resources in the resource block is N, s is greater than or equal to 1 and less than or equal to N, it should be noted that the resource block, that is, the whole of the wireless resource, is formed into a resource block by a plurality of wireless resources, and there is no limitation on the size.
And 105, judging whether the N wireless resources in the resource block are all called, if so, exiting the scheduling program, otherwise, returning to the step 103 after updating the real-time operation data information based on a preset updating formula until the wireless resources in the resource block are all called.
After each scheduling cycle is finished, that is, after all users are scheduled according to the user scheduling priority of a certain time slot, whether all wireless resources of the resource block are scheduled is judged, if so, step 106 is executed, and if not, the real-time operation data information is updated according to a preset updating formula, and then the step 103 is returned. It can be understood that, in order to ensure fairness of scheduling, after each scheduling period is finished, real-time operation information of each user needs to be updated, as more resources are allocated to users, the scheduling priority of the user is gradually reduced until the scheduling priority is lower than that of the user with the lower initial priority, so that the user with the lower initial priority obtains a scheduling opportunity.
Generally, in order to ensure the scheduling reasonableness, all the radio resources of a resource block are not scheduled in one scheduling period.
And step 106, exiting the scheduling program.
And finishing scheduling after all the wireless resources of the resource block are scheduled.

The technical problem that differentiated wireless resource scheduling service cannot be provided while wireless resources are scheduled fairly for users in the prior art, and the utilization rate of the wireless resources is low is solved.
The foregoing is a first embodiment of a method for scheduling wireless resources of a power communication network provided in the embodiment of the present application, and the following is a second embodiment of the method for scheduling wireless resources of a power communication network provided in the embodiment of the present application.
Referring to fig. 2, a flowchart of a second embodiment of a method for scheduling wireless resources in an electric power communication network according to the present application is shown.
It can be understood that when the user needs the wireless resource, a scheduling request is sent to the scheduler, and the scheduler obtains the user's instantaneous amount of data to be sent, instantaneous data transmission rate, instantaneous access delay, data average transmission rate and maximum access delay in response to the user's request.
It should be noted that enhanced mobile broadband (e MBB), mass machine type communication (m MTC), and ultra-reliable low-latency communication (u RLLC) in a 5G application scenario are three types of typical services of a wireless network, and service features corresponding to the three types of typical services are data volume, transmission rate, and latency, respectively, so that the wireless network is divided into three types of network slices, namely, enhanced mobile broadband (e MBB), mass machine type communication (m MTC), and ultra-reliable low-latency communication (u RLLC), and acquiring required data types according to service features corresponding to the three types of network slices includes: the amount of data sent, the data transmission rate, and the access delay.
The description of step 202 is the same as step 102 in the first embodiment, and reference may be specifically made to the description of step 102, which is not repeated herein.
And 203, calculating the scheduling priority of the user based on a preset scheduling priority calculation formula according to the real-time operation data information and the weight of the real-time operation data information.
In this embodiment, the preset scheduling priority calculation formula is as follows:
in the formula, αi、βi、γiWeights α for three performance indicators of user i's data transmission rate, amount of data to be sent, and access delayi、βi、γiAre all less than 1 and greater than 0, and αi、βi、γiThree weights added equal to 1, Ri(t) is the average data transmission rate of the users in two time slots i before the moment t, ri(t) data transmission rate, λ, for user at time tCFor maximum access delay, λi(t) access delay already generated from packet data packet of user i to t time slot, ci(t) for the amount of data to be sent by user i at time t,
amount of data to be transmitted, P, for all users at time ti(t) is the scheduling priority of user i at time t, and N represents the number of users.
And step 204, scheduling the wireless resource s in the resource block to the user based on the scheduling priority.
It should be noted that the description of step 204 is the same as that of step 104 in the first embodiment, and reference may be specifically made to the description of step 104, which is not described herein again.
After one scheduling cycle is finished, it needs to determine whether the radio resource in the resource block has been scheduled, if the radio resource in the resource block has been scheduled, step 208 is executed, otherwise, step 206 or step 207 is executed.
It can be understood that, when the radio resource of the resource block is not scheduled, in order to ensure that the next scheduling is more reasonable, the resource block needs to be scheduled according to the new scheduling priority, so the average data transmission rate and the instantaneous access delay need to be updated, and the scheduling priority is calculated according to the updated average data transmission rate and the updated instantaneous access delay.
It should be noted that, when the radio resource that is not scheduled in the resource block is greater than or equal to the radio resource required by the next iteration cycle, the data average transmission rate is updated by a first formula, where the first formula is:
when the wireless resource which is not scheduled in the resource block is smaller than the wireless resource required by the next iteration period, updating the average data transmission rate by a second formula, wherein the second formula is as follows:
in the formula, Ri(t) is the average data transmission rate, i.e. average throughput, of the users in two time slots i before the moment t; t is tcIs the reference time slot number; r isi(t) is the data transmission rate of the user at time i; the first formula is used when there are sufficient radio resources to schedule to the client and the second formula is used when there are insufficient radio resources to schedule to the client.
The instantaneous access delay updating formula is as follows:
in the formula, λCFor maximum access delay, λi(t) is the access delay already generated from the packet data packet of the user i to the t time slot; i (t) is the power spectral density of t time slots.
And step 208, exiting the scheduling program.
And when the wireless resource in the resource block is scheduled, finishing the scheduling.
And 209, calculating the scheduling satisfaction of the user according to the real-time operation data information based on a preset satisfaction function.
It should be noted that the scheduling satisfaction of the user can be calculated through a preset satisfaction function, so as to check the scheduling effect.
The preset satisfaction function is:
in the formula, ηiIndicating the amount of data user i has sent over a period of time in the past ξiRepresenting the total amount of data to be transmitted by user i during the past period;iindicating the radio resource acquired by user i, i.e. the satisfaction of user i,ia larger size indicates a more satisfactory scheduling of radio resources for the user.
Referring to fig. 3, fig. 3 is a simulation result diagram of the satisfaction of the method for scheduling wireless resources of the power communication network in the embodiment.
As can be seen from fig. 3, the scheduling method of the present application can well ensure fairness of user resource scheduling. Meanwhile, the descending trend tends to be gentle along with the increase of the number of users.
According to the power communication network wireless resource scheduling method provided by the embodiment, firstly, a user scheduling request is responded, based on analysis of service characteristics of three major typical services, namely e MBB, m MTC and u RLLC, in a 5G application scene, a network slice to which a user belongs is specially used as a priority measurement factor of the user, so that a sending data volume, a data transmission rate and an access delay are required to be obtained as indexes for calculating the user scheduling priority, and the scheduling priority of the user is calculated according to the weights of the three characteristic indexes, an instantaneous data volume to be sent, an instantaneous data transmission rate, an instantaneous access delay, a data average transmission rate and a maximum access delay, so that the differentiated requirements of each user are met; considering scheduling fairness, after each scheduling period is finished, real-time operation information of each user needs to be updated, and as more resources are allocated to the users, the scheduling priority of the users is gradually reduced until the scheduling priority is lower than the users with lower initial priority, so that the initial priority is lower and scheduling opportunities are obtained; finally, fairness inspection is carried out on the scheduling method of the embodiment through a user satisfaction function, and according to a simulation result, the scheduling method of the embodiment can well guarantee fairness of user resource scheduling. The technical problem that differentiated wireless resource scheduling service cannot be provided while wireless resources are scheduled fairly for users in the prior art, and the utilization rate of the wireless resources is low is solved.

In this embodiment, first, according to a scheduling request of a user, real-time operation data information of the user, that is, operation data information of each time slot is obtained; the individual characteristics of the users can be determined through the network slicing characteristics, and further the weights are set according to the network slicing characteristics, so that the weight of each type of data in the real-time operation data information is determined according to the network slicing characteristics of the users, then the scheduling priority during wireless resource scheduling is determined according to the real-time operation data information and the corresponding weights, namely the determination of the scheduling priority is determined according to the individual characteristics of the users, and the wireless resource scheduling performed through the scheduling priority meets the individual characteristics and differentiation requirements of the users; meanwhile, considering scheduling fairness, after each scheduling period is finished, real-time running information of each user needs to be updated, the scheduling priority of the user is gradually reduced along with more resources obtained by the user until the scheduling priority is lower than that of the user with the lower initial priority, so that the user with the lower initial priority obtains scheduling opportunities, and scheduling fairness is further ensured.
