Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application are capable of operation in sequences other than those illustrated or described herein, and that the terms "first," "second," etc. are generally used in a generic sense and do not limit the number of terms, e.g., a first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The resource allocation method, device, electronic device and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

With the continuous development of 5G network technology and the continuous popularization of terminal applications, commercialization of a network slicing function, which is an important feature of a 5G network, is also being promoted. The network slicing means that an operator divides a network into network channels with different characteristic dimensions according to different user requirements, different network service qualities are provided on different channels, specific types of network services are provided for different users, and the fine improvement of user internet experience is realized.

The types of network slices are mainly low delay slices, high bandwidth slices, and the like. For example, low latency slices are mainly applied in game scenes, and such network slices are characterized by: the transmitted data has a low bandwidth requirement and the delay requirement is very low. The high bandwidth slice is mainly applied to an online video scene, and the network slice is characterized in that: a certain degree of delay can be tolerated at the higher bandwidth rates required. The operator selects the corresponding slice type on the network side according to the data transmitted from the terminal to the network side, and adopts a corresponding configuration strategy to realize the transmission characteristics of the corresponding slice.

Specifically, the terminal generates data during the application running process, the terminal sends the generated data to the corresponding network slice directly sent to the operator network, and then the operator network adopts different processing logics to transmit the data of different types of network slices. For example, after the terminal runs the game application APP1 or runs the video application APP2 to generate data, the data of the APP1 or APP2 sends the data of the APP1 to the network slice corresponding to the operator network by using the same slice policy, and finally, the operator network transmits the data by using the processing logic of the network side corresponding to the low-delay slice according to the data type. Or the terminal system sends the data of the APP2 to the operator network by using the same slicing strategy, and finally, the operator network transmits the data by using the processing logic of the network side corresponding to the high-bandwidth slice according to the data type.

It can be seen that there is no method for effectively ensuring slicing characteristics when application data generated by a terminal is still in the terminal before being sent to an operator network: firstly, when the terminal sends data, the terminal only sends the application data to the corresponding slices respectively, and does not identify the characteristics of the slices, and the same strategy is adopted for the transmission of the data on all types of network slices. Therefore, the data on each network slice uses the same strategy when being transmitted, so that the data compete for resources and affect each other, thereby causing data loss.

In the resource allocation method provided in the embodiment of the present application, the terminal receives network slice information from the network side device, where the network slice information includes information of slice characteristics of at least one network slice supported by the network side device, so that the terminal can determine a resource allocation policy corresponding to each network slice according to the information of the slice characteristics of the at least one network slice, and further, the terminal can allocate a corresponding slice resource to each network slice according to the resource allocation policy. Therefore, the terminal can configure appropriate corresponding slice resources for different network slices according to different slice characteristics corresponding to different network slices, so that the terminal can use different slice resource strategies to send data to the operator network, and data loss caused when the same strategy is used to send data is avoided.

An execution subject of the resource configuration method provided by the embodiment of the application may be a training device of a face recognition model, and the resource configuration device may be an electronic device (e.g., a terminal), or a functional module in the electronic device. The following describes the technical solutions provided in the embodiments of the present application, taking a terminal as an example.

An embodiment of the present application provides a resource allocation method, and fig. 1 shows a flowchart of the resource allocation method provided in the embodiment of the present application. As shown in fig. 1, the resource allocation method provided in the embodiment of the present application may include steps 201 to 203 described below.

Step 201, the terminal receives network slice information from the network side device.

In an embodiment of the present application, the network slice information includes: a slicing feature of at least one network slice supported by the network-side device.

In the embodiment of the present application, the slice features may be a low latency slice, a high bandwidth slice, a high security slice, and the like.

For example, after the terminal is attached to the core network, the network side device sends network slice information to the terminal, and the terminal may establish a slice feature mapping table according to information of slice features in the network slice information.

Illustratively, the slice characteristic mapping table is created based on information of slice characteristics of each network slice in the network slice information and stored in the terminal.

Step 202, the terminal determines a resource allocation policy corresponding to a first network slice in the at least one network slice based on the slice characteristic of the first network slice.

For example, the first network slice may be a plurality of network slices, or may be a single network slice.

Illustratively, the first network slice is any network slice of the at least one network slice.

Illustratively, the terminal receives the network slice information and configures different slice resources for network slices with different slice characteristics according to the information of the slice characteristics of the first network slice in the network slice information.

For example, as shown in fig. 2, the method for configuring different slice resources for network slices with different slice characteristics includes the following steps S1 to S4:

and S1, after the terminal is plugged in the card, the terminal can be attached to a 5G core network.

And S2, after the network attachment is successful, the network side equipment reports network slice information to the terminal, wherein the network slice information comprises the data types which can be transmitted and are supported by each network slice in the network side equipment and the characteristics of each network slice, such as high bandwidth requirement or high delay requirement.

And S3, the terminal acquires the slicing characteristics of the network slices and the data types supporting transmission by inquiring the slicing characteristic mapping table.

And S4, the terminal allocates resources for the slices according to the characteristics of the slices. For example, a higher CPU preemption authority and a shorter CPU execution time are allocated to a low-latency slice with a low latency requirement, and a higher protocol stack scheduling authority is also allocated at the same time; allocating a larger I/O buffer area for a high-bandwidth slice with high bandwidth rate requirement; and configuring a resource replacement mode, namely a hardware encryption mode and the like for the high-security slice with high security requirement.

Step 203, the terminal configures resources for a first network slice in the at least one network slice based on the resource allocation policy.

In a first possible embodiment:

optionally, in this embodiment of the present application, when the slice feature of the first network slice is a low-latency slice, in the process of "the terminal configures resources for the first network slice in at least one network slice based on the resource allocation policy" in step 203a:

step 203a, the terminal configures a high CPU right and a preset transmission duration for the first network slice, and only allows the first network slice to transmit data within the preset transmission duration.

Illustratively, the high CPU right is used to indicate that the first network slice has the highest CPU transfer right.

For example, the preset transmission duration may be set by the system or may be customized by the user.

For example, the preset transmission duration is a priority protection period of the first network slice, that is, the first network slice is prioritized and allowed to transmit data only in the priority protection period.

In a second possible embodiment:

optionally, in this embodiment of the present application, when the slice feature of the first network slice is a high bandwidth slice, in the process of "the terminal configures resources for the first network slice in the at least one network slice based on the resource allocation policy" in step 203, the step 203b is included:

and step 203b, the terminal configures an I/O cache region for the first network slice.

In an example, when the first network slice cannot transmit data, the to-be-transmitted data packet corresponding to the first network slice is stored in an I/O cache area configured for the first network slice by the terminal.

In one example, in a case that the first network slice may transmit data, the to-be-transmitted data packet corresponding to the first network slice stored in the I/O buffer is read and transmitted.

In a third possible embodiment:

optionally, in this embodiment of the present application, in the process of "the terminal configures resources for the first network slice in the at least one network slice based on the resource allocation policy" in the step 203, when the slice feature of the first network slice is a high security slice, the step 203c is included:

and 203c, before the terminal transmits the data based on the first network slice, encrypting the data transmitted by the first network slice based on a hardware encryption mode.

Illustratively, the hardware encryption scheme described above may replace the software encryption scheme in the first network slice.

In the resource allocation method provided by the embodiment of the present application, a terminal may receive network slice information from a network side device, where the network slice information includes a slice feature of at least one network slice supported by the network side device; determining a resource allocation strategy corresponding to a first network slice in at least one network slice based on the slice characteristics of the first network slice; resources are configured for the first network slice based on the resource allocation policy. Therefore, the terminal can configure appropriate corresponding slice resources for different network slices according to different slice characteristics corresponding to different network slices, so that the terminal can use different slice resource strategies to send data to an operator network, and data loss caused when the same strategy is used to send data is avoided.

Optionally, in this embodiment of the present application, the resource configuration method provided in this embodiment of the present application further includes the following steps 301 and 302:

step 301, under the condition that the terminal runs the first application, the terminal determines a target slice feature matched with a slice type corresponding to a first data packet of the first application.

For example, the first application may be any application installed in a terminal, and this is not limited in this embodiment of the application.

Illustratively, the target slice characteristic is a slice characteristic of a network slice corresponding to the first packet of the first application.

Step 302, the terminal transmits a first data packet of the first application based on the target network slice corresponding to the target slice feature.

Illustratively, the target network slice is one or more of the at least one network slice.

In one example, the network slice information obtained by the terminal may further include: the type of data matched to each network slice.

Illustratively, the target network slice matches a data type corresponding to the first data packet.

It should be noted that, when the target network slice corresponding to the first application transmits the first data packet, the used resource may be a resource configured in advance by the system; alternatively, after determining the target network slice, the system configures the corresponding resource for the target network slice based on the target slice characteristic of the target network slice.

Optionally, in an embodiment of the present application, the first data packet includes a first flag, and the first flag is used to indicate the target network slice.

Illustratively, the first marker may be a slice identifier of the target network slice.

In one example, after determining a network slice corresponding to a first packet of a first application, the terminal adds a first flag to the first packet.

Further optionally, in this embodiment of the application, the "transmitting the first data packet of the first application based on the target network slice corresponding to the target slice feature" in the step 302 includes step 302a:

step 302a, transmitting a first data packet of a first application including the first marker based on a target network slice corresponding to the target slice feature.

A scenario in which the terminal runs the first application in the embodiment of the present application will be exemplarily described below with a specific example.

Exemplarily, as shown in fig. 3, in a scenario where a terminal runs a first application, a technical solution provided in an embodiment of the present application includes the following steps A1 to A4:

step A1, when a first application in the terminal is running, the application may need to perform data transmission with the operator network. For example, when a game is played, a terminal needs to perform data transmission with a game server, and when an online video is viewed, a video file or the like needs to be downloaded from a video server.

And step A2, when the terminal sends the data generated by different applications, the data can be transmitted through different network slices. For example, data generated by a gaming application may be transmitted via low latency slices, and data generated by a video application may be transmitted via high bandwidth slices. And the terminal selects corresponding network slices for data generated by different applications according to the network slice information reported by the network side equipment for transmission.

Step A3, after the terminal selects the network slice corresponding to the data generated by the application, the system marks slice information (i.e. the first mark) of the network slice on a data packet (i.e. the first data packet) formed by the data generated by the application, and then the terminal processes the data packet accordingly according to the mark.

And step A4, after the marking is finished, the terminal processes the sending, including the processing of a network protocol stack, the sending of data and the like.

Therefore, the terminal can select the corresponding slice resource strategy to transmit data according to the slice characteristics corresponding to different application data packets, and the flexibility of slice transmission data is improved.

Illustratively, based on the above resource allocation strategy, when the slice is used to transmit data, slice resource scheduling can be directly performed.

A scenario of scheduling resources when a terminal transmits data in the embodiment of the present application will be exemplarily described below with a specific example.

Exemplarily, as shown in fig. 4, in a scenario where resource scheduling is performed when a terminal transmits data, a technical solution provided in an embodiment of the present application includes the following steps B1 to B16:

step B1, before the terminal transmits the marked data packet, the terminal will first obtain the slice information (i.e. the first mark) marked on the current data packet.

And step B2, the terminal acquires the slice characteristic information corresponding to the network slice to be used by the data packet according to the established slice characteristic mapping table.

And step B3, the terminal judges the slice characteristic information corresponding to the network slice and selects a proper resource scheduling path. Step B4 is entered if the used network slice is a low latency slice, step B11 is entered if the used network slice is a high bandwidth slice, and step B15 is entered if the used network slice is a high security slice.

Step B4, the slice resources allocated by the terminal to the low-delay slice comprise: the high CPU preemption authority can interrupt the low priority task currently in progress. Therefore, the terminal firstly acquires the priority of the task currently executed by the CPU, compares the priority with the priority of the low-delay slice, judges whether the task can be interrupted or not, and preferentially executes the sending task of the low-delay slice.

And step B5, the terminal judges the priority of the task currently executed by the CPU, if the priority of the currently executed character is lower than the sending task of the low-delay slice, the step B6 is executed, otherwise, the step B7 is executed.

And step B6, the terminal judges that the priority of the task executed by the current CPU is lower than the priority of the task of sending the low-delay slice, so that the task executed by the current CPU is temporarily interrupted, and the task of sending the low-delay slice is switched to be executed.

And step B7, the terminal judges that the priority of the task executed by the current CPU is higher than that of the sending task of the low-delay slice and cannot be interrupted, and waits for the completion of the execution of the current task.

And step B8, after the sending task of the low-delay slice obtains the CPU resource, the terminal sets the CPU protection level for the currently executed task, only the task higher than the set CPU protection level can preempt the CPU, the sending process of the current low-delay slice is interrupted, and other tasks of low level cannot preempt the CPU.

And step B9, simultaneously, after the sending task of the low-delay slice acquires the CPU resource, the terminal sets a priority protection period for the protocol stack, and in the priority protection period, only the sending task of the low-delay slice is allowed to be executed, and the sending tasks of other types of slices are waited first.

And step B10, the terminal sends the data packet to a network protocol stack for processing, and then sends the data packet to the operator core network through the network card.

And step B11, the CPU preemption authority in the slice resources distributed by the terminal for the high-bandwidth slice is lower, and the CPU resources can be obtained only after the CPU finishes executing the current task.

And step B12, the terminal judges whether the protocol stack is in the protection period of the low-delay slice sending task, if not, the step B10 is entered, and the terminal sends the data to the network protocol stack for processing. Otherwise, go to step B13.

Step B13, if the protocol stack can not process the sending task of the high bandwidth at present, the slice resources allocated for the high bandwidth slices by the terminal include: and the terminal firstly puts the data into the I/O buffer area.

And step B14, after the protection period of the protocol stack is finished and the sending task of the high-bandwidth slice can be processed, the terminal takes the data cached in the I/O buffer area, enters the step B10 and sends the data to the network protocol stack for processing.

Step B15, the data of the high security slice needs to be encrypted before being sent, so that the slice resources allocated by the terminal to the high security slice include: and resource replacement, namely, the terminal uses hardware encryption instead of software encryption to perform encryption operation on the data transmitted by the high-security slice.

And step B16, hardware encryption can provide higher encryption speed and security level, after the terminal completes data encryption, the terminal enters step B10, and the terminal sends the data to a network protocol stack for processing.

Therefore, the terminal can schedule the system resources according to the characteristics of the slices without modifying the existing slice specifications, the terminal can schedule the system resources according to the characteristics of the slices on the basis of the original specifications without active participation of users, the error rate caused by the participation and the change of the users is avoided, the implementation scheme is more intelligent, the user operation is simpler and more convenient, and the high-efficiency transmission of data is ensured.

Fig. 5 is a system architecture diagram applied to the resource allocation method according to the embodiment of the present application. As shown in fig. 5, the terminal in this embodiment of the present application includes a slice policy management module, a slice selection policy module, and a resource scheduling module.

Specifically, the core network reports all slice information supported by the network slices to the slice policy management module of the terminal, so that the slice policy management module can allocate different slice resources according to the slice characteristics of different network slices. When the terminal runs the third-party application, application data can be generated, the slice selection strategy of the terminal selects a proper network slice according to the application data generated by the third-party application, and then the resource scheduling module of the terminal can correspondingly schedule resources for transmission of the application data according to the slice characteristics of the network slice corresponding to the current application data.

Illustratively, the slicing policy management module: the system is responsible for receiving network slice information reported by a core network, establishing a mapping relation among characteristics of different network slices, and determining a corresponding resource allocation strategy according to the slice characteristics of the different network slices. For example, a priority protection period is configured for the low-latency slice, only data transmission of the low-latency slice is allowed in the priority protection period, and the high CPU preempts the right; configuring a data buffer (i.e. the I/O buffer) for the high-bandwidth slice, so that when the high-bandwidth slice is not used for receiving data in time, data loss does not occur, and the bandwidth is kept at a higher rate; and a specific encryption and decryption mode is configured for the data of the high-security slice, for example, software implementation is replaced by hardware implementation, so that higher-level security guarantee is provided.

A slice selection policy module: and selecting an appropriate slice for the data of the third-party application according to the slice information of the network slice and the request of the third-party application.

A resource scheduling module: according to the slice characteristics used when the terminal sends the data generated by the current application, allocating appropriate resources for the application: CPU execution time, CPU preemption authority, I/O buffer, protocol stack scheduling authority, slice resource replacement and the like. Therefore, the data transmitted on different slices can obtain corresponding system resources.
