Detailed Description
The embodiment of the application provides a method and a device for scheduling wireless resources of an electric power communication network, which solve the technical problems that the prior art cannot provide differentiated wireless resource scheduling service and cannot fairly schedule wireless resources for users, so that the utilization rate of the wireless resources is low.
In order to make the present application better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, a flowchart of a first embodiment of a wireless resource scheduling method for an electric power communication network according to an embodiment of the present application is shown.
The wireless resource scheduling method of the power communication network in the embodiment comprises the following steps:
and step 101, responding to a user scheduling request and acquiring real-time operation data information of a user.
It will be appreciated that when a user needs radio resources, a scheduling request is sent to a scheduler, which obtains real-time operation data information of the user in response to the user's request.
Step 102, the weight of the real-time operation data information is configured 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, 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 user are determined according to the characteristics of the network slice in which the user is located, so that the weight of the user real-time operation data information is determined by the characteristics of the network slice in which the user is located, and the differentiated requirements of each user are met.
Substituting the real-time operation data information and the weight of the real-time operation data information of the user into a preset dispatching priority calculation formula, and calculating to obtain the dispatching priority of the user.
Step 104, based on the scheduling priority, the radio resource s in the resource block is scheduled to the user.
The number of radio resources in the resource block is N, s is 1-N, and it should be noted that the resource block, that is, the whole of radio resources, is formed by a plurality of radio resources, and is not limited in size, it can be understood that, according to the calculated user scheduling priority, the radio resources in the resource block are scheduled to the user, and the size of the radio resources scheduled to the user is determined according to the actual requirement, at this time, the radio resources which have been scheduled are set to be occupied, so that the radio resources need to be set to an unavailable state.
Step 105, judging whether N wireless resources in the resource block are all called, if yes, exiting the scheduling program, if no, returning to 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 period 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 yes, step 106 is executed, if not, the real-time operation data information is updated according to a preset updating formula, and then step 103 is returned. It can be understood that, in order to ensure fairness of scheduling, after each scheduling period is finished, the real-time running information of each user needs to be updated, and as the users are allocated more resources, the scheduling priority of the users gradually decreases until the scheduling priority is lower than that of the users with lower initial priority, so that the users with lower initial priority obtain scheduling opportunities.
In general, in order to ensure the rationality of scheduling, all radio resources of a resource block are not scheduled in one scheduling period.
And 106, exiting the scheduler.
And after all the wireless resources of the resource block are scheduled, ending the scheduling.
According to the wireless resource scheduling method of the power communication network, firstly, real-time operation data information of a user, namely operation data information of each time slot, is obtained according to a scheduling request of the user; the individual characteristics of the user can be determined through the network slice characteristics, and further the weights are set according to the network slice characteristics, so that the weight of each type of data in the real-time operation data information is determined according to the network slice characteristics of the user, then the scheduling priority in the wireless resource scheduling is determined according to the real-time operation data information and the corresponding weights, namely the scheduling priority is determined according to the individual characteristics of the user, and the individual characteristics and the differentiation requirements of the user are met through the wireless resource scheduling carried out through the scheduling priority; meanwhile, considering the fairness of scheduling, after each scheduling period is finished, the real-time running information of each user needs to be updated, and as the resources obtained by the users are more, the scheduling priority of the users can be gradually reduced until the scheduling priority is lower than that of the users with lower initial priority, so that the users with lower initial priority can obtain scheduling opportunities, and the fairness of scheduling is further ensured. The method solves the technical problem that the prior art can not provide differentiated wireless resource scheduling service while fairly scheduling wireless resources for users, so that the wireless resource utilization rate is low.
The above is an embodiment one of a power communication network radio resource scheduling method provided by the embodiment of the present application, and the following is an embodiment two of a power communication network radio resource scheduling method provided by the embodiment of the present application.
Referring to fig. 2, a flow chart of a second embodiment of a wireless resource scheduling method for an electric power communication network according to an embodiment of the present application is shown.
Step 201, in response to a user scheduling request, acquiring an instantaneous data volume to be sent, an instantaneous data transmission rate, an instantaneous access time delay, a data average transmission rate and a maximum access time delay of a user.
It will be appreciated that when a user requires radio resources, a scheduling request is sent to a scheduler, which, in response to the user's request, 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.
It should be noted that, in the 5G application scenario, the enhanced mobile broadband (embb), the mass machine type communication (emtc) and the ultra-reliable low-latency communication (u RLLC) are three types of typical services of the wireless network, and the service characteristics corresponding to the three types of typical services are respectively transmission data volume, transmission rate and latency, so that the wireless network is divided into three types of network slices of the enhanced mobile broadband (embb), the mass machine type communication (emtc) and the ultra-reliable low-latency communication (u RLLC), and the required data types are obtained according to the service characteristics corresponding to the three types of network slices, including: the data volume, the data transmission rate and the access delay are transmitted.
Step 202, the weight of the real-time operation data information is configured according to the network slice characteristics of the user.
The description of step 202 is the same as that of step 102 in the first embodiment, and specific reference may be made to the description of step 102, which is not repeated here.
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, a preset scheduling priority calculation formula is:
wherein alpha is i 、β i 、γ i Weights of three performance indexes, namely data transmission rate, data quantity to be transmitted and access time delay of user i, alpha i 、β i 、γ i Are all less than 1 and greater than 0, and alpha i 、β i 、γ i The three weights add to equal 1, R i (t) is the average transmission rate of data of users in two time slots i before the moment t, r i (t) data transmission rate of i user at time t lambda C Lambda is the maximum access delay i (t) packet data packet for user iAccess delay already generated by t time slot c i (t) the amount of data to be transmitted for user i at time t,for the data volume to be transmitted by all users at time t, P i And (t) is the scheduling priority of the user i at the moment t, and N represents the number of users.
Step 204, based on the scheduling priority, scheduling the radio resource s in the resource block to the user.
It should be noted that, the description of step 204 is the same as that of step 104 in the first embodiment, and specific reference may be made to the description of step 104, which is not repeated here.
Step 205, determining whether N radio resources in the resource block are all invoked, if yes, executing step 208, otherwise, executing step 206 or step 207.
After a scheduling period is finished, it needs to be determined whether the radio resources in the resource block have been scheduled, if yes, step 208 is performed, otherwise, step 206 or step 207 is performed.
Step 206, after updating the data average transmission rate based on the data average transmission rate updating formula, returning to step 203.
Step 207, after updating the instantaneous access delay based on the instantaneous access delay updating formula, returning to step 203.
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 that the data average transmission rate and the instantaneous access delay need to be updated, and the scheduling priority is calculated according to the updated data average transmission rate and the instantaneous access delay.
It should be noted that, when the unscheduled radio resource in the resource block is greater than or equal to the radio resource required by the next iteration period, the average data transmission rate is updated by a first formula, where the first formula is:
when the unscheduled wireless resource in the resource block is smaller than the wireless resource required by the next iteration period, updating the data average transmission rate through a second formula, wherein the second formula is as follows:
wherein R is i (t) is the average transmission rate, i.e. the average throughput, of the data of the users of the two time slots i by the time t; t is t c Is the reference time slot number; r is (r) i (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 update formula is:
wherein lambda is C Lambda is the maximum access delay i (t) an access delay that has been created from packet data packet to t slots for user i; i (t) is t time slot power spectral density.
Step 208, exiting the scheduler.
And when the wireless resources in the resource block are scheduled, ending the scheduling.
Step 209, calculating the scheduling satisfaction of the user according to the real-time operation data information based on the preset satisfaction function.
It should be noted that, the scheduling satisfaction degree of the user can be calculated through a preset satisfaction degree function, so as to check the scheduling effect.
The preset satisfaction function is:
wherein eta is i Representing the amount of data that user i has sent over a period of time; zeta type toy i Representing the total amount of data to be transmitted by user i during the past period; Γ -shaped structure i Representing the radio resources obtained by user i, i.e. the satisfaction of user i, Γ i A larger indicates that the user is satisfied with scheduling radio resources.
Referring to fig. 3, fig. 3 is a diagram showing simulation results of satisfaction of a wireless resource scheduling method of an electric power communication network in the present embodiment.
As can be seen from fig. 3, the scheduling method of the present application can well ensure fairness of user resource scheduling. Meanwhile, as the number of users increases, the descending trend tends to be gentle.
According to the wireless resource scheduling method of the power communication network, firstly, a user scheduling request is responded, based on analysis of service characteristics of three typical services of eMBB, mMTC and uRLLC in a 5G application scene, the network slice characteristics of the user are taken as priority measurement factors of the user, so that the transmission data volume, the data transmission rate and the access time 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 weights of the three characteristic indexes, the instantaneous data volume to be transmitted, the instantaneous data transmission rate, the instantaneous access time delay, the data average transmission rate and the maximum access time delay, and the differentiated requirements of each user are guaranteed to be met; considering the fairness of scheduling, after each scheduling period is finished, the real-time operation information of each user needs to be updated, and the scheduling priority of the user gradually decreases as the user is allocated more resources until the scheduling priority is lower than that of the user with lower initial priority, so that the initial priority is lower to obtain scheduling opportunities; finally, the fairness check is performed on the scheduling method of the embodiment through the user satisfaction function, and according to the simulation result, the scheduling method of the embodiment can be known to ensure the fairness of the scheduling of the user resources well. The method solves the technical problem that the prior art can not provide differentiated wireless resource scheduling service while fairly scheduling wireless resources for users, so that the wireless resource utilization rate is low.
