Example 1
Referring to fig. 1, a network slice allocation method according to a first embodiment of the present invention is shown, and the method specifically includes steps S101 to S104:
s101, acquiring a target network slice set and a power service set, wherein the target network slice set comprises all network slices, and the power service set comprises all power services;
specifically, when a user who needs to use electric energy sends a service request to a power supply enterprise such as a national network by using a user terminal, a power service set is generated at this time, each power service in the power service set is acquired, in this process, each network slice for processing each power service is acquired, and in specific implementation, each network slice for processing each power service, preferably a 5G network slice, is acquired.
S102, calculating average time throughput of each network slice in the target network slice set based on each power service, and obtaining total spitting and swallowing amounts of each network slice, wherein each network slice comprises an eMBB slice and a uRLLC slice;
in the specific implementation, in the process of processing each power service by each network slice, since most of data is bursty and time is high and low when each network slice receives processing data, the average time throughput of each network slice in the process of processing each power service by each network slice is calculated, and the total throughput of each network slice is obtained.
Specifically, in the present embodiment, the simulation parameters of the eMBB slice and the wrlc slice are set as shown in table 1:
in the table 1 of the description,
，
s103, setting a limiting condition according to the total throughput, and formulating an optimization function of each network slice based on the limiting condition, wherein the optimization function is as follows:
；
；
；
；
；
；
where A represents a vector of RBs, RBs represent resource blocks, P represents a vector of power allocations,、/>representing the number of devices in said emmbc slice, the number of devices in said uRLLC slice, respectively, ">，/>M and N each represent a natural number, +.>Indicate->Resource blocks->，/>、/>Is indicated at->gNB and apparatus、/>Transmission power between->Representing the device in said eMBB slice,/or->Representing the device in said uRLLC slice, wherein +.>、/>Binary variables: />、/>Respectively indicate whether or not will +>Assigned to、/>、/>、/>Respectively representing the buffer queue length of the eMBB slice and the uRLLC slice when the service is requested,/and/or>Representing a delay constraint, rm representing throughput of the eMBB slice, t representing time, pm representing power of devices in the eMBB slice, pn representing power of devices in the uRLLC slice, dn representing power in the uRLLC sliceIs a set of requirements for the device;
it should be explained that, after the network slices are optimized, the length of the service request list can be processed by determining that each network slice meets the requirements of time delay and the like, so that each network slice is more efficient and reliable in processing the power service request.
S104, evaluating the total throughput of each network slice, determining the optimal matching strategy of each network slice and each power service, and distributing each power service to each network slice according to the optimal matching strategy;
in the implementation, after the total throughput of each network slice is calculated, that is, the number of successful transmission data of each network slice in unit time is obtained, the power service suitable for processing of each network slice is evaluated, and because of different power services, the number of the required processing data is also different, and the optimal matching strategy of each network slice and each power service is designated according to the number of the successful transmission data of each network slice in unit time, so that each network slice can process the corresponding power service, thereby effectively improving the capability of each network slice for processing data and further effectively improving the applicability of each network slice.
Further, each power service is processed through each network slice, so that each power service is isolated, the speed of processing each power service is effectively improved, the problem that the efficiency of processing the power service is reduced due to overhigh processing time delay is avoided, and the isolated network slices are not affected each other, so that each network slice is more reliable in the process of processing each power service.
It should be noted that, in this embodiment, when each power service is allocated to each network slice, an RA-DT algorithm is adopted to perform allocation, specifically, allocation is performed based on the proposed RA-DT algorithm, and the effects of the two conventional schemes on the throughput of the eMBB slice and the ul lc slice are evaluated, and referring to fig. 2, a schematic diagram of the effects of the simulation parameters set by the eMBB slice and the ul lc slice on the throughput of each network slice under different resources is shown in this embodiment.
In summary, in the network slice allocation method in the above embodiment of the present invention, firstly, a slice set and a power service set of a target network are obtained to obtain each power service and each network slice for processing each power service, then, by calculating an average time throughput of each network slice and a total throughput of each network slice based on each power service, that is, a number of data transmitted by each network slice in unit time, then, according to a data volume of each power service, the total throughput of each network slice is evaluated, an optimal matching policy of each network slice and each power service is determined, so that each network slice can process each power service corresponding to each network slice, and then, each power service is allocated to each network slice according to the optimal matching policy, so that each network slice can efficiently process the corresponding power service, and efficiency of processing transmission data of each network slice is effectively improved, and a "dedicated network" can be created according to a power service type to meet different quality of power service (QoS) requirements of different users, thereby providing better service requirements for users.
Example two
Referring to fig. 3, a network slice allocation method according to a second embodiment of the present invention is shown, and the method includes steps S201 to S209:
s201, acquiring a target network slice set and a power service set, wherein the target network slice set comprises all network slices, and the power service set comprises all power services;
specifically, when a user who needs to use electric energy sends a service request to a power supply enterprise such as a national network by using a user terminal, a power service set is generated at this time, and each power service in the power service set is acquired, in this process, each network slice for processing each power service is acquired, and in specific implementation, each network slice for processing each power service, preferably a 5G network slice, in this embodiment, each network slice includes an eMBB slice and a ullc slice, where the eMBB slice serves enhanced mobile broadband services similar to unmanned aerial vehicle inspection, video monitoring, and the ullc slice serves ultra-high reliable, low-latency, and other services similar to power distribution automation.
S202, acquiring an electric power service request and/or a temporary electric power service request, wherein each electric power service comprises the electric power service request and/or the temporary electric power service request;
in a specific implementation, after the power service set is acquired, the power service request and/or the temporary power service request are acquired in the power service set, it can be understood that the data volume required to be transmitted by the two power service requests is different, the data volume in the temporary power service request is smaller, the data volume in the non-temporary power service request is larger, and the requirements of the two services on the time delay are also different, the temporary power service request may need to be processed very quickly, so that the requirements on the time delay of the temporary power service request may be lower, the non-temporary power service request has a certain buffer time, so that the requirements on the time delay have a certain tolerance, and the time delay of the non-temporary power service request may be higher than the time delay of the temporary power service request.
S203, creating a service request list of each network slice based on the power service request and/or the temporary power service request;
in particular implementations, the power service request and/or the temporary power service request require a network slice to be processed, and before processing, a service request list is created according to the time when the power service request and/or the temporary power service request is received, so as to achieve a "make before go" procedure, so that the network slice is processed according to the receiving time when the power service request and/or the temporary power service is processed.
S204, acquiring the data transmission rate of each network slice in real time;
s205, limiting the length of the service request list based on the data transmission rate of each network slice;
in a specific implementation, since the processing rate of the server is limited, in order to ensure the quality of service (QoS), the network slice has to reject the arrival of a new power service request, so that the existing power service request tends to be in a stable state, and waits for the processing of the network slice, otherwise, the requirements of low delay and high reliability of the network slice cannot be met, so that the length of a service request list needs to be limited, and the unstable situation caused by the fact that the processing of the network slice is not finished is avoided.
S206, calculating average time throughput of each network slice in the target network slice set based on each power service, and obtaining total throughput of each network slice, wherein each network slice comprises an eMBB slice and a uRLLC slice;
s207, setting a limiting condition according to the total throughput so that each network slice meets the limiting condition, and optimizing each network slice;
s208, expanding the average time throughput to the maximum limit value of the limiting condition based on the limiting condition;
specifically, the constraint includes RB (resource block) and power, and an optimization function is specified based on the constraint, so that each network slice satisfies the constraint,
in particular, in this embodiment, each network slice includes an eMBB slice and a ul lc slice, and each network slice is required to satisfy the RB and power constraints, so that，Wherein, A represents RB, P represents a power distribution vector, and each network slice randomly optimizes a problem function specifically formulated as follows:
；
；
；
；
；
；
where A represents a vector of RBs, RBs represent resource blocks, P represents a vector of power allocations,、/>representing the number of devices in said emmbc slice, the number of devices in said uRLLC slice, respectively, ">，/>M and N each represent a natural number, +.>Indicate->Resource blocks->，/>、/>Is indicated at->On gNB and device->、/>Transmission power between->Representing the device in said eMBB slice,/or->Representing the device in said uRLLC slice, wherein +.>、/>Binary variables: />、/>Respectively indicate whether or not will +>Assigned to->、/>、/>、/>Respectively representing the buffer queue length of the eMBB slice and the uRLLC slice when the service is requested,/and/or>Representing a delay constraint, rm representing throughput of the eMBB slice, t representing time, pm representing power of devices in the eMBB slice, pn representing power of devices in the uRLLC slice, dn representing a set of requirements of devices in the uRLLC sliceCombining;
it should be explained that, after the network slices are optimized, the length of the service request list can be processed by determining that each network slice meets the requirements of time delay and the like, so that each network slice is more efficient and reliable in processing the power service request.
S209, evaluating the total throughput of each network slice, determining the best matching strategy of each network slice and each power service, and distributing each power service to each network slice according to the best matching strategy;
in the implementation, each network slice is optimized, the length of a power service request list which can be processed when each network slice meets the time delay requirement is determined, then the total throughput of each network slice is calculated, the total throughput of each network slice is evaluated, and the optimal matching strategy of each network slice and each power service is determined, so that each network slice can process each power service corresponding to each network slice, each power service is distributed to each network slice according to the optimal matching strategy, each network slice can efficiently process the corresponding power service, the efficiency of processing transmission data of the network slice is effectively improved, a special network can be created according to the type of the power service, and different service quality (QoS) requirements in different power service scenes are met, so that better service is provided for users.
In summary, compared with the first embodiment, the network slice allocation method in the above embodiment of the present invention can set a constraint condition based on the total throughput, so that each network slice is optimized after meeting the constraint condition, so that the length of the power service request list processed by each network slice under the condition that each network slice meets the delay requirement is determined, and each network slice can meet the quality of service (QoS) to process each power service.
