These drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
The terms referred to in this application are explained first:
edge computing server: the method is characterized in that a service platform constructed at the network edge side close to a user provides resources such as storage, calculation, network and the like, and a part of key service application is sunk to the access network edge so as to reduce the width and delay loss caused by network transmission and multistage forwarding.
Calculating service slices: refers to a task slice generated by the edge computation server based on the traffic packetization parameters.
For a clear understanding of the technical solutions of the present application, the prior art solutions will be described in detail first.
In the conventional manner, the edge computing server of the base station where the mobile terminal to be processed initiates the service is usually preferentially computed by the edge computing server of the base station serving as the scheduling node, and when the computing power of the edge computing server of the base station is insufficient, the edge computing servers of other base stations are selected and invoked nearby to process, thereby completing the service processing of the mobile terminal. However, in this way, the edge computing server of the base station participates in the computing process more, so that the scheduling capability as a scheduling node is weakened.
Therefore, when facing the technical problems in the prior art, the inventor finds out after creative research that in order to avoid weakening the scheduling capability of the edge computing server of the base station, the edge computing server of the base station can perform scheduling management better. After a service processing request of a mobile terminal to be processed is acquired, a plurality of calculation service slices are determined based on the service processing request, a plurality of target mobile terminals are determined according to the slice calculation power specification of the calculation service slices, the plurality of calculation service slices are processed to obtain corresponding slice processing results, and therefore service package processing results required by the mobile terminal to be processed are obtained according to the slice processing results. In the implementation process, the edge computing server is mainly used as a dispatching node to acquire a service processing request, determine a computing service slice and distribute the computing service slice to a target mobile terminal for computing. That is, the edge computing server no longer participates in the computing process of the mobile terminal to be processed preferentially, but mainly performs task scheduling as a scheduling node. Therefore, by adopting the processing mode, the scheduling capability of the edge computing server of the base station can be prevented from being weakened, and the edge computing server of the base station can be ensured to perform scheduling management better.
As shown in fig. 1, the application scenario of the mobile terminal edge computing method provided in the embodiment of the present application may be applied to a 5G edge computing system, where a network architecture corresponding to the application scenario includes a mobile terminal 10 to be processed, an edge computing server 20 of a first base station, and a target mobile terminal 30. The pending mobile terminal 10 is a mobile terminal that initiates a service processing request and is communicatively coupled to a first base station. At least one edge calculation server can be set in each base station, and the execution subject of the application is the edge calculation server 20 of the first base station (i.e. the edge server of the base station), and the edge calculation server 20 of the first base station, the mobile terminal 10 to be processed and the target mobile terminal 30 are in communication connection. After the mobile terminal 10 to be processed initiates the service processing request, the edge computing server 20 of the first base station is used as a scheduling node to determine a plurality of computing service slices according to the service processing request, and the computing service slices may include n computing service slices 1 and n computing service slices n are only shown in fig. 1. And then screening to obtain the target mobile terminal 30 according to the slice calculation power specification of the calculation service slice. The computing service slice is scheduled to the corresponding target mobile terminal 30, as shown in fig. 1, the target mobile terminal 30 includes m, and only the target mobile terminal 1 and the target mobile terminal m are shown in the figure. If the target mobile terminal 30 obtains the calculated service slice, the calculated service slice is processed to obtain a corresponding slice processing result. After the edge calculation server 20 of the first base station acquires the slicing result, the slicing result is sent to the mobile terminal 10 to be processed. Under the condition that no network drop occurs, the number of m and n is equal, and if the target mobile terminal occurs the network drop, the m is possibly smaller than n.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
In the following embodiments, the first slice processing result, the second slice processing result, and the third slice processing result are all slice processing results after the computation service slice is processed.
Fig. 2 is a schematic diagram of a mobile terminal edge computing method according to an embodiment of the present application, and as shown in fig. 2, an execution body of the mobile terminal edge computing method according to the embodiment is an edge computing server of a first base station where a mobile terminal to be processed is located. The mobile terminal edge computing method provided by the embodiment comprises the following steps:
step 101, obtaining a service processing request of a mobile terminal to be processed, wherein the service processing request comprises a service sub-packet parameter.
The mobile terminal to be processed is a mobile terminal with service processing requirements, and when the mobile terminal to be processed has the service processing requirements, a corresponding service processing request is initiated to a first base station where the mobile terminal to be processed is located. The service processing request comprises service sub-packet parameters, wherein the service sub-packet parameters are parameters corresponding to each service sub-packet obtained after splitting the parameters of the complete service packet. If the calculation power requirement specification of the parameters of the complete service packet is smaller (for example, smaller than the calculation power requirement threshold), the parameters of the complete service packet may not be split, and at this time, the service sub-packet parameters in the service processing request are the parameters of the complete service packet. If the calculation power requirement specification of the parameters of the complete service package is larger (for example, greater than or equal to the calculation power requirement threshold), the parameters of the complete service package are generally split to obtain the parameters corresponding to each service sub-packet, so that the 5G edge computing system is convenient for calculation power sharing, an edge computing server of a certain base station cannot appear, and congestion phenomenon occurs due to bearing of larger calculation power requirement.
Before the service processing request of the mobile terminal to be processed is obtained, the parameters of the complete service packet can be split to obtain one or more service sub-package parameters in the mobile terminal to be processed, or the parameters of the complete service packet can be split to obtain one or more service sub-package parameters in the edge calculation server of the first base station.
The obtaining of the service processing request of the mobile terminal to be processed may be that the mobile terminal to be processed actively triggers reporting and obtaining when the refresh context or the user touch/voice input is monitored.
Step 102, determining a plurality of computation service slices based on the service packetization parameters.
The calculating service slice refers to a task slice generated by an edge calculating server according to the service sub-packet parameters, and the calculating service slice comprises the service sub-packet parameters. The calculation service slices are determined according to the calculation power requirement specification in the service sub-packaging parameters, wherein the calculation power requirement specification comprises the calculation power size and the calculation power type required by calculating the service sub-packaging parameters, and the plurality of calculation service slices at least meet the calculation power requirement specification of the service sub-packaging parameters.
Step 103, screening to obtain a plurality of target mobile terminals according to the slice calculation power specification of the calculation service slice; the target mobile terminal is a mobile terminal for processing the calculation service slice.
Wherein the slice computation power specification includes computation power size and type of the computation service slice. The target mobile terminal is a mobile terminal for processing the calculation service slice. When the plurality of target mobile terminals are obtained through screening, the calculation power of the candidate mobile terminals can be determined by comparing the calculation power with the slicing calculation power specification.
And 104, dispatching the calculated service slices to the corresponding target mobile terminals for processing so as to obtain corresponding slice processing results.
Specifically, each calculation service slice is respectively scheduled to a corresponding target mobile terminal for processing, typically one calculation service slice is scheduled to one target mobile terminal, and calculation processing is performed by using a calculation resource and a storage resource pair of the target mobile terminal so as to obtain a corresponding slice processing result. The slice processing result refers to a processing result obtained after the calculation service slice is subjected to the calculation processing of the target mobile terminal.
And 105, obtaining a service packet processing result according to the slicing processing result, and sending the service packet processing result to the mobile terminal to be processed.
And obtaining the service package processing result in a combined and spliced mode according to the slicing processing result. The service package processing result is the processing result required by the mobile terminal to be processed to initiate the service processing request. After the service packet processing result is obtained, the edge computing server of the first base station sends the service packet processing result to the mobile terminal to be processed.
According to the mobile terminal edge computing method provided by the embodiment, a service processing request of a mobile terminal to be processed is obtained, wherein the service processing request comprises service sub-package parameters; determining a plurality of calculated service slices based on the service packetization parameters; screening to obtain a plurality of target mobile terminals according to the slice calculation power specification of the calculation service slice; the target mobile terminal is a mobile terminal for processing the calculation service slice; dispatching the calculated service slices to corresponding target mobile terminals for processing so as to obtain corresponding slice processing results; and obtaining a service packet processing result according to the slicing processing result, and sending the service packet processing result to the mobile terminal to be processed. In the processing process, an edge computing server is mainly used as a dispatching node to acquire a service processing request of a mobile terminal to be processed, determine a computing service slice and distribute the computing service slice to a target mobile terminal for computing. The edge computing server does not participate in the computing process of the mobile terminal to be processed preferentially any more, but mainly serves as a dispatching node for task dispatching. Therefore, by adopting the processing mode, the scheduling capability of the edge computing server of the base station can be prevented from being weakened, and the edge computing server of the base station can be ensured to perform scheduling management better.
As an alternative implementation manner, as shown in fig. 3, in this embodiment, step 105, obtaining a service packet processing result according to the slice processing result includes the following steps:
step 201, comparing the slice processing result with a corresponding pre-stored expected processing result.
The expected processing result is a processing result achieved after the mobile terminal to be processed expects to calculate the service slice to be processed. Comparing the slice processing result obtained by the actual processing with the pre-stored expected processing result, it can be determined whether the service packet processing result can be determined according to the slice processing result obtained by the actual processing. The pre-stored expected processing result may be that when the mobile terminal to be processed performs an operation, the server of the merchant providing the operation sends the expected processing result to the edge computing server of the first base station. Taking cloud game as an example, in the process of playing a game through a mobile terminal to be processed, a game server of a game service provider can send a game picture and interaction operation at the next moment to an edge computing server of a first base station as expected processing results to be stored in advance, so that slicing processing results are obtained at the next moment, and then comparison is carried out.
And step 202, if the slicing processing result is determined to be consistent with the corresponding expected processing result, determining the slicing processing result as a first slicing processing result, and obtaining a service package processing result according to the first slicing processing result.
The slicing processing result includes a case where the service packet processing result can be obtained and a case where the service packet processing result cannot be obtained. The basis of the judgment is whether the slice processing result is consistent with the pre-stored expected processing result. The first slicing result refers to a slicing result from which a service packet processing result can be obtained. And obtaining a service package processing result according to the first slicing processing result.
Comparing the slicing processing result with a corresponding prestored expected processing result; and if the slicing processing result is consistent with the corresponding expected processing result, determining the slicing processing result as a first slicing processing result, and obtaining a service packet processing result according to the first slicing processing result. Since the service packet processing result is obtained based on the first slice processing result in accordance with the desired processing result, the accuracy of the service packet processing result can be ensured.
As an optional implementation manner, in this embodiment, the service processing request further includes a service class, and step 103 includes the following steps:
step 301, determining the delay sensitivity degree of the service according to the service type.
The business categories include games, meta universe, blockchain, model prediction and the like. The time delay sensitivity degree of the service refers to the degree of speed of the service type needing the dispatching processing of the edge computing server to obtain the processing result of the service packet. Different service types have different time delay sensitivity degrees of the service, and when a target mobile terminal is screened, the target mobile terminal can be screened according to the time delay sensitivity degree of the service corresponding to the service type, so that the mobile terminal to be processed with high time delay sensitivity degree requirement of the service can obtain a service packet processing result as soon as possible.
In addition, considering the time delay sensitivity degree of the service is also beneficial to reasonable scheduling, for example, when a plurality of mobile terminals to be processed initiate service processing requests at the same time, the edge computing server of the first base station can perform scheduling computation for the mobile terminals to be processed with high time delay sensitivity degree requirements of the service preferentially according to different service types, and delay the mobile terminals to be processed with low time delay sensitivity degree requirements of the service to perform scheduling computation, so that scheduling congestion is avoided.
And step 302, screening to obtain a plurality of target mobile terminals according to the slice computing power specification of the computed service slices and the time delay sensitivity degree of the service.
Specifically, whether the slice calculation power specification of the calculated service slice is met is firstly determined, and the time delay sensitivity degree of the service is considered in a combined mode on the basis that the slice calculation power specification is met so as to screen and obtain a plurality of target mobile terminals.
According to the mobile terminal edge computing method provided by the embodiment, the time delay sensitivity degree of the service is determined according to the service type; and screening to obtain a plurality of target mobile terminals according to the slice calculation force specification of the calculated service slice and the time delay sensitivity degree of the service. When a plurality of target mobile terminals are screened, the time delay sensitivity screening of the service is further combined, so that the mobile terminal to be processed can be guaranteed to obtain the service package processing result more quickly.
As an alternative implementation, in this embodiment, step 302 includes the following steps:
step 401, determining whether the delay sensitivity degree of the service reaches a preset degree.
The preset degree comprises the degrees of very sensitivity, general sensitivity and the like, and the very sensitivity is set to be the preset degree.
Step 402, if the delay sensitivity degree of the service reaches a preset degree, in the mobile terminal in communication connection with the first base station, a plurality of target mobile terminals are obtained by screening according to the slice calculation power specification of the calculated service slice.
If the delay sensitivity of the service reaches a preset level, the service type is very sensitive to the delay. As shown in fig. 4, if the target mobile terminal is located in the first base station, a service processing request is initiated from the mobile terminal to be processed to an edge computing server of the first base station, the edge computing server of the first base station dispatches the computed service slice to the target mobile terminal, the target mobile terminal returns the slice processing result to the edge computing server of the first base station, and the edge computing server of the first base station returns the service packet processing result to the mobile terminal to be processed. This whole process requires only a duration of d+c+d+c in terms of transmission delay. Compared with the screening of other base stations to obtain the target mobile terminal, in order to enable the mobile terminal to be processed to obtain the service packet processing result as soon as possible, the screening of the target mobile terminal in the first base station is prioritized. The edge server of the first base station obtains a mobile terminal in communication connection with the first base station, and screens the mobile terminal in communication connection with the first base station according to the slicing calculation power specification to obtain a plurality of target mobile terminals.
And step 403, if the delay sensitivity degree of the service does not reach the preset degree, selecting and obtaining a plurality of target mobile terminals according to the slice calculation power specification of the calculated service slice in the mobile terminals which are in communication connection with each second base station in the preset area range.
The preset area range may include administrative levels such as province, city, district, etc. The second base station refers to a base station within a preset area, and is distinguished from the first base station in terms of name. If the time delay sensitivity degree of the service does not reach the preset degree, the service type is generally sensitive to the time delay. If the target mobile terminal is in each second base station within the preset area range, the duration from the initiation of the service processing request to the acquisition of the service packet processing result of the mobile terminal to be processed is longer than d+c+d+c. As shown in fig. 4, the service packet processing result is obtained from the mobile terminal to be processed by the metropolitan area network private line to the local province/home city core network, the local province/home city core network to the outer province/outer city core network through the metropolitan area network private line, and the outer province/outer city core network to the target mobile terminal through the metropolitan area network private line. This whole process requires a duration of d+b+j+e+g+h+f+k+a+c in terms of transmission delay. Therefore, when the delay sensitivity degree of the service does not reach the preset degree, the target mobile terminal can be screened from the second base stations in the preset area range.
According to the mobile terminal edge computing method provided by the embodiment, whether the time delay sensitivity degree of the service reaches a preset degree is judged; if the time delay sensitivity degree of the service reaches a preset degree, in the mobile terminals which are in communication connection with the first base station, a plurality of target mobile terminals are obtained through screening according to the slice calculation power specification of the calculated service slice; and if the time delay sensitivity degree of the service does not reach the preset degree, selecting and obtaining a plurality of target mobile terminals in the mobile terminals which are in communication connection with each second base station in the preset area according to the slice calculation power specification of the calculated service slice. Whether the time delay sensitivity degree of the service reaches a preset degree or not is determined, and a target mobile terminal is obtained by screening in the mobile terminals in communication connection with the first base station or the second base station, so that a mobile terminal to be processed which is very sensitive to the time delay of the service can obtain a service packet processing result as soon as possible, and the mobile terminal to be processed which is generally sensitive to the time delay of the service can have more choices.
As an optional implementation manner, in this embodiment, if it is determined that there is at least one slice processing result inconsistent with the corresponding expected processing result or the corresponding slice processing result is not obtained, the mobile terminal edge calculating method includes the following steps:
And step 501, if the delay sensitivity degree of the service reaches a preset degree, at least one calculation service slice which is scheduled to be processed by the fault target mobile terminal is scheduled to be processed by an edge calculation server of the first base station, so as to obtain a corresponding second slice processing result.
The fault target mobile terminal refers to a target mobile terminal with network drop.
After the network is disconnected, the fault target mobile terminal cannot process the calculation service slice to obtain a slice processing result consistent with the corresponding expected processing result or obtain a corresponding slice processing result. At this time, if the delay sensitivity of the service reaches a preset level, it indicates that the service type of the mobile terminal to be processed is very sensitive to the delay, and if the target mobile terminal is reselected, a certain time will be consumed in screening the target mobile terminal. Therefore, the plurality of fault calculation service slices are preferentially scheduled to the edge calculation server of the first base station for processing, the target mobile terminal does not need to be screened, and the corresponding second slice processing result can be obtained more quickly.
And step 502, obtaining a corresponding third slice processing result still processed by the target mobile terminal.
The method comprises the steps that except for the fact that the computing service slices of the fault target mobile terminals are processed by the edge server of the first base station, other computing service slices are still processed by all target mobile terminals, and corresponding slice processing results are obtained and are called third slice processing results.
And step 503, obtaining the service packet processing result according to the second slice processing result and the third slice processing result, and sending the service packet processing result to the mobile terminal to be processed.
Specifically, the edge computing server of the first base station may obtain the service packet processing result by combining and splicing the second slice processing result and the third slice processing result, and send the service packet processing result to the mobile terminal to be processed.
According to the mobile terminal edge computing method provided by the embodiment, if the time delay sensitivity degree of the service reaches the preset degree, at least one computing service slice which is scheduled to be processed by the fault target mobile terminal is scheduled to the edge computing server of the first base station for processing, so that a corresponding second slice processing result is obtained; obtaining a corresponding third slice processing result still processed by the target mobile terminal; and obtaining the service packet processing result according to the second slice processing result and the third slice processing result, and sending the service packet processing result to the mobile terminal to be processed. When the time delay sensitivity degree of the service reaches a preset degree, the calculated service slice of the fault target mobile terminal is scheduled to an edge calculation server of the first base station for processing, so that a service packet processing result can be obtained as soon as possible, and the time delay requirement of the service is met.
In this embodiment, if it is determined that at least one slice processing result is inconsistent with the corresponding expected processing result or the corresponding slice processing result is not obtained, the mobile terminal edge computing method further includes step 601, and if the delay sensitivity degree of the service does not reach the preset degree, step 103 is executed, and a plurality of target mobile terminals are obtained by screening according to the slice calculation power specification of the computed service slice.
Specifically, if the delay sensitivity degree of the service does not reach the preset degree, the service type of the mobile terminal to be processed is generally sensitive to the delay. At this time, the edge computing server of the first base station is preferentially guaranteed to serve as the scheduling capability of the scheduling node, the computing work of the edge computing server is reduced, and the target mobile terminal can be reselected.
According to the mobile terminal edge computing method provided by the embodiment, if at least one slice processing result is inconsistent with the corresponding expected processing result or the corresponding slice processing result is not obtained, if the time delay sensitivity degree of the service does not reach the preset degree, the step of screening and obtaining a plurality of target mobile terminals according to the slice computing force specification of the computing service slice is executed. When the time delay sensitivity degree of the service does not reach the preset degree, the edge computing server of the first base station can be ensured to be used as a dispatching node as far as possible by rescreening the target mobile terminal.
As an optional implementation manner, in this embodiment, the selecting and obtaining a plurality of target mobile terminals according to the slice computing power specification of the computing service slice includes the following steps:
in step 701, real-time load sensing is performed on each mobile terminal in communication connection with the current base station through the current base station, so as to determine whether an idle mobile terminal exists, wherein the current base station is the first base station or the second base station, and the idle mobile terminal is a mobile terminal capable of meeting the slicing calculation power specification.
For the first base station or the second base station, each mobile terminal in communication connection with the first base station or the second base station is subjected to real-time load sensing through the current base station, and the load condition of the mobile terminal is sensed, including CPU operation, storage occupation and the like, so that whether an idle mobile terminal exists or not is determined. The idle mobile terminal refers to a mobile terminal in an idle state, and the idle state can be a state in which no task is completely idle, or a state in which no service such as video, game and the like is running. The idle mobile terminal is a mobile terminal capable of meeting the slice calculation power specification.
Step 702, if the idle mobile terminal exists, screening and obtaining a plurality of target mobile terminals from at least the idle mobile terminals.
The idle mobile terminal has no task execution or occupies less CPU and memory resources, so the idle mobile terminal has more sufficient CPU and memory resources. If the idle mobile terminal exists, when the target mobile terminal is screened, a plurality of target mobile terminals are screened from the idle mobile terminal preferentially. And during screening, at least screening a plurality of target mobile terminals from the idle mobile terminals.
If the idle mobile terminal does not exist, step 703 is executed to screen and obtain a plurality of target mobile terminals from the mobile terminals communicatively connected to the current base station according to the slice calculation power specification of the calculation service slice.
If no idle mobile terminal exists, a plurality of target mobile terminals can be obtained by screening from all mobile terminals in communication connection with the current base station only according to the slice calculation power specification of calculating the service slice.
According to the mobile terminal edge computing method provided by the embodiment, real-time load sensing is performed on each mobile terminal in communication connection with the mobile terminal through the current base station so as to determine whether an idle mobile terminal exists, wherein the current base station is the first base station or the second base station, and the idle mobile terminal is a mobile terminal capable of meeting the slicing calculation power specification; if the idle mobile terminal exists, screening and obtaining a plurality of target mobile terminals from at least the idle mobile terminal; and if the idle mobile terminal does not exist, executing screening from all mobile terminals in communication connection with the current base station according to the slice calculation power specification of the calculation service slice to obtain a plurality of target mobile terminals. When an idle mobile terminal exists, the idle mobile terminal can be preferentially screened as a target mobile terminal. When the idle mobile terminal does not exist, the target mobile terminal is screened according to the slicing calculation power specification, and the target mobile terminal meeting the slicing calculation power specification can be obtained.
As an alternative implementation manner, in this embodiment, step 702 includes the following steps:
step 801, obtaining the number of idle mobile terminals.
The number of the idle mobile terminals is the total number of all idle mobile terminals of the current base station.
Step 802, determining whether the number of idle mobile terminals is greater than or equal to the number of the computing service slices.
The number of idle mobile terminals is compared with the number of the calculated service slices, so as to determine whether the number of the idle mobile terminals meets the requirement of calculating the number of the service slices.
And step 803, if the number of the idle mobile terminals is smaller than the number of the calculated service slices, determining the idle mobile terminals as target mobile terminals, and screening and obtaining the target mobile terminals from the running mobile terminals according to the slice calculation power specification of the calculated service slices.
If the number of the idle mobile terminals is smaller than the number of the calculated service slices, all the idle mobile terminals are determined to be target mobile terminals. However, at this time, some of the computing service slices do not obtain the corresponding target mobile terminals, and the edge computing server of the first base station screens and obtains the remaining target mobile terminals from the running mobile terminals of the current base station according to the slice computing power specification. The running mobile terminal refers to a mobile terminal in a running state, and the running state can be a state when running services such as video, games and the like. The running mobile terminal may or may not meet the slice calculation power specification, and therefore, it is further determined whether the calculation power of the running mobile terminal meets the slice calculation power specification according to the slice calculation power specification.
Step 804, if the number of the idle mobile terminals is greater than or equal to the number of the calculation service slices, selecting and obtaining a plurality of target mobile terminals from the idle mobile terminals according to the slice calculation power specification of the calculation service slices.
And if the number of the idle mobile terminals is greater than or equal to the number of the calculated service slices, selecting a plurality of idle mobile terminals from all the idle mobile terminals according to the slice calculation power specification of the calculated service slices to obtain corresponding target mobile terminals (namely, selecting a plurality of target mobile terminals).
According to the mobile terminal edge computing method provided by the embodiment, the number of the idle mobile terminals is obtained; judging whether the number of the idle mobile terminals is larger than or equal to the number of the calculation service slices; if the number of the idle mobile terminals is smaller than the number of the calculation service slices, determining the idle mobile terminals as target mobile terminals, and screening from the operation mobile terminals according to the slice calculation power specification of the calculation service slices to obtain the target mobile terminals; and if the number of the idle mobile terminals is greater than or equal to the number of the calculation service slices, screening and obtaining a plurality of target mobile terminals from the idle mobile terminals according to the slice calculation power specification of the calculation service slices. By comparing the number of idle mobile terminals with the number of service slices, the number of idle mobile terminals which can be screened as target mobile terminals can be accurately determined, and the number of target mobile terminals which need to be screened according to the slice calculation force specification can be accurately determined.
As an alternative implementation, in this embodiment, step 703 includes:
step 901, if the idle mobile terminal does not exist, acquiring hardware configuration parameters of each mobile terminal in communication connection with the current base station.
The hardware configuration parameters may represent the computational power of the mobile terminal, and include a CPU, a GPU (graphics processing unit, i.e., a graphics processor), and storage, among others. The hardware configuration parameters are at the beginning of the communication connection between each mobile terminal and the current base station, i.e. the own IMEI (i.e. International Mobile Equipment Identity, international mobile equipment identity) has been reported to the current base station. After the current base station acquires the device codes of each mobile terminal, each device code can be stored in an edge computing server of the current base station.
And if the idle mobile terminal does not exist, the edge calculation server of the first base station acquires the hardware configuration parameters of the mobile terminals in communication connection with the current base station from the edge calculation server of the current base station.
Step 902, comparing each hardware configuration parameter with the slice calculation power specification.
Specifically, the CPU, memory in the hardware configuration parameters are compared with the CPU, memory correspondence in the slice calculation power specification. The hardware configuration parameters may also include GPUs, etc.
And step 903, screening the mobile terminals with the hardware configuration parameters larger than the slicing calculation power specification as the target mobile terminals to obtain a plurality of target mobile terminals.
And screening the CPU and the mobile terminal stored in the hardware configuration parameters which are larger than the CPU and the mobile terminal stored in the slicing calculation power specification as target mobile terminals to obtain a plurality of target mobile terminals.
According to the mobile terminal edge computing method provided by the embodiment, if the idle mobile terminal does not exist, hardware configuration parameters of the mobile terminals in communication connection with the current base station are obtained; comparing each hardware configuration parameter with the slicing calculation force specification respectively; and screening the mobile terminals with the hardware configuration parameters larger than the slicing calculation power specification as the target mobile terminals to obtain a plurality of target mobile terminals. By comparing the hardware configuration parameters with the slicing calculation power specification, only mobile terminals with hardware configuration parameters larger than the slicing calculation power specification are screened as target mobile terminals, so that the screened target mobile terminals can be ensured to meet the calculation business slicing calculation power specification.
As an optional implementation manner, in this embodiment, step 102, determining a plurality of computing service slices based on the service packetization parameter includes:
In step 1001, a calculated service slice is determined based on the service packetization parameter.
Specifically, the calculation service slice is determined according to the calculation power requirement specification in the service sub-packet parameters. In general, the edge computing server of the first base station may uniformly split parameters of a complete service packet into a plurality of service sub-packet parameters, and for the case of splitting into a plurality of service sub-packet parameters, determine a computed service slice for each service sub-packet parameter.
Step 1002, performing redundancy backup on the computing service slices to obtain a plurality of computing service slices.
Specifically, for one calculation service slice, in order to prevent the network drop condition after the corresponding target mobile terminal is dispatched, redundant backup is performed on the calculation service slice, so as to obtain a plurality of calculation service slices identical to the calculation service slice. For example, an A1 computation service slice is determined based on the service packetization parameter a, and the A1 computation service slice is redundantly backed up by 2 to obtain 3 identical A1 computation service slices.
According to the mobile terminal edge computing method provided by the embodiment, a computing service slice is determined based on the service sub-packaging parameters; and carrying out redundancy backup on the computing service slices to obtain a plurality of computing service slices. By carrying out redundant backup on the calculated service slices, the condition that the target mobile terminal is dropped can be prevented, and the service processing result can be obtained more stably.
As an optional implementation manner, the embodiment further includes, before step 503, step 1101 of rejecting a plurality of identical slice processing results so as to make each slice processing result unique, where the slice processing result is the first slice processing result or the third slice processing result.
Specifically, as described above, after redundant backup is performed on the computation service slices, a plurality of identical computation service slices are obtained, and slice processing results obtained after the plurality of identical computation service slices are processed by the corresponding target mobile terminals are identical. For the mobile terminal to be processed, one slice processing result is obtained, and other identical slice processing results are redundant. Therefore, the edge computing server of the first base station will reject a plurality of identical slice processing results, but only one of the slice processing results is reserved, so that each slice processing result is unique.
When the calculation service slice is scheduled for processing, only the target mobile terminal may be dropped, redundant backup is needed, and the edge calculation server of the first base station does not drop, so that redundant backup is generally not needed. Since only redundant backups are performed, multiple identical slice processing results are generated, and therefore multiple identical computation service slices are removed only when the target mobile terminal is processing. The first slicing result and the third slicing result are slicing results obtained after the processing by the target mobile terminal, so that a rejection operation is required.
According to the mobile terminal edge computing method provided by the embodiment, a plurality of identical slice processing results are removed, so that each slice processing result is unique, and the slice processing result is the first slice processing result or the third slice processing result. And eliminating a plurality of identical slicing processing results generated by redundant backup, so that the slicing processing results are unique, and the data redundancy of the edge computing server of the first base station is reduced.
As an alternative embodiment, in this embodiment, the slicing processing results are any one of the following results: a combined result of slicing processes and the first slicing process result, the combined result of slicing processes including the second slicing process result and the third slicing process result, step 105, comprising the steps of:
if the number of the slice processing results is determined to be one, the slice processing result is determined to be a service packet processing result in step 1201.
Specifically, if the calculation power requirement specification of the parameters of the complete service packet of the mobile terminal to be processed is smaller, the service processing request only includes one service sub-packet parameter, only one calculation service slice is determined, after redundancy backup and multiple identical slice processing results are removed, only one number of slice processing results is obtained, and the slice processing results are determined as service packet processing results.
In step 1202, if the number of the slice processing results is determined to be multiple, each slice processing result is combined, and the combined result is determined to be a service packet processing result.
Specifically, if the calculation force requirement specification of the parameters of the complete service packet of the mobile terminal to be processed is larger, dividing the parameters of the complete service packet into a plurality of service sub-packet parameters, determining to obtain corresponding calculation service slices, performing redundancy backup on the plurality of calculation service slices and removing a plurality of identical slice processing results, obtaining a plurality of slice processing results, combining the slice processing results through a combination splicing technology, and taking the combined result as a service packet processing result.
In the mobile terminal edge computing method provided by the embodiment, if the number of the slicing processing results is determined to be one, the slicing processing results are determined to be service packet processing results; and if the number of the slice processing results is determined to be a plurality of, combining the slice processing results, and determining the combined result as a service packet processing result. Whether one or a plurality of slicing processing results are obtained, the edge computing server of the first base station dispatches the slicing processing results to the target mobile terminal for processing so as to obtain service packet processing results, and therefore the edge computing server of the first base station can better maintain a dispatching function.
As an optional implementation manner, this embodiment further includes, before step 103, step 1301, screening out the mobile terminals whose signal strength is greater than the strength threshold. Step 103, selecting and obtaining a plurality of target mobile terminals from the mobile terminals larger than the intensity threshold according to the slice calculation force specification of the calculated service slice.
The signal strength is greater than the strength threshold, which indicates that the signal strength is better, and the base station switching and network dropping possibility is lower. When the target mobile terminal is screened, the signal strength and the computing power are taken as important consideration factors, so that a more suitable target mobile terminal can be selected.
In the above embodiments, before the computing service slice is scheduled to the target mobile terminal, the edge computing server of the first base station may first send a message about whether to share computing to the target mobile terminal, if the user clicks to determine that joining is desired, the computing service slice may be processed by using the target mobile terminal, otherwise, the target mobile terminal is redetermined, and user privacy infringement is not involved.
