This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office of China, the application number is 201910979542.0, and the invention title is "Resource allocation method and device and system for in-vehicle business slicing" on October 15, 2019, and its entire contents Incorporated in this application by reference.

Technical field

This application relates to the field of Internet of Vehicles, and in particular to a resource allocation method, device, and system for in-vehicle business slicing.

Background technique

The in-car system provides safety, entertainment, and energy-saving functions to the vehicle. At present, in-vehicle systems carry different service requirements through different bus standards, and different electronic control units (ECUs) perform their own missions while working, and exchange data and control commands through different data network protocols. With the rapid development of in-vehicle electronic systems, the number of ECUs in the vehicle, the demand for computing power, and the demand for communication bandwidth have increased significantly. Therefore, the future in-vehicle systems will evolve in the following directions: a single ECU can be responsible for multiple needs, the in-vehicle computing power and storage resources are centralized, and the hardware used in the bus in the vehicle is unified.

However, although the in-vehicle system evolves in the above direction, it is necessary to ensure the computing resources, storage resources, and transmission resources required by each in-vehicle business, that is, to realize the isolation of the above-mentioned resources in different types of in-vehicle business.

A conventional fifth generation (5 ^th generation, 5G) slicing technology network is a mobile communication system transmission resources isolation method. 5G network slicing technology provides isolated network environments for different application scenarios by virtual independent logical networks on the same network infrastructure, so that different application scenarios can customize network functions and features according to their own needs, and can effectively guarantee different services Quality of service (QoS) requirements. The goal of 5G network slicing is to organically combine terminal equipment, access network resources, core network resources, and network operation and maintenance and management systems, so as to provide independent operation and maintenance for different business scenarios or types of services. The internet.

As shown in Figure 1, the existing 5G network slicing diagram includes enhanced mobile broadband (eMBB) slicing, ultra-reliable-low latency communication (URLLC) slicing, and large-scale Internet of Things (massive internet of things) slices, etc. In the 5G mobile network architecture, the terminal device is the data input terminal, the application server of the business layer is the data processing terminal, and the terminal device and the application server of the business layer are not controlled by the operator. Therefore, the 5G network slicing mainly focuses on the terminal to the gateway. The slice of the network transmission between the network (as shown in the dashed box in Figure 1) does not involve the terminal and service processing capabilities. The in-vehicle system is a closed and end-to-end complete system that not only includes data input modules such as sensors, but also data processing modules such as autonomous driving platforms. Therefore, the in-vehicle system not only needs to slice on transmission resources, but also needs to realize slice isolation on computing resources and storage resources.

Therefore, the existing 5G slicing technology does not fully meet the requirements of the in-vehicle system. It is necessary to design an end-to-end resource allocation plan for in-vehicle business slicing to achieve resource allocation and isolation between in-vehicle business slicing to meet different business needs.

The capability description information of the service slice is used to indicate the first resource configuration information required by the service slice corresponding to the in-vehicle service data in the in-vehicle system.

This embodiment provides a mutually isolated in-vehicle network environment for different business application scenarios by virtual independent logical networks on a unified hardware resource, so that different business application scenarios can customize network functions and characteristics according to their needs, which can effectively guarantee Service quality requirements of different businesses. Specifically, the in-vehicle business includes the following types of business slices: autonomous driving business slices, in-car entertainment business slices, and body safety control business slices.

Illustratively, the following describes the functions provided by the autonomous driving business slice, the in-car entertainment business slice, and the car body safety control business slice:

Autonomous driving business slice: The security level is high, and powerful software and hardware technical support is required. A variety of sensors (such as binocular cameras, three-dimensional laser scanning radar) cooperate with each other to form an integrated intelligent network. For example: autonomous cruise system, remote garage parking, and automatic driving functions that follow the car in front safely in traffic jams are all within the scope of this slice, so the resources occupied by the data transmission of the autonomous driving business slice urgently need to be guaranteed . It should be noted that the names of the above-mentioned automatic driving service slice types are just examples, and may also be other expressions, such as driving service slices, intelligent driving service slices, and so on.

In-car entertainment business slice: the security level is low, and the entertainment system is mainly used to allow drivers to enjoy entertainment.

The data transmission resources required for the car body safety control slice can be lower than the autonomous driving business slice. It should be noted that the names of the above-mentioned vehicle body safety control business slice types are just examples, and may also be expressed in other ways, such as vehicle body control slices, smart body safety business slices, and so on.

It should be noted that the in-vehicle business slices in the present invention include but are not limited to the above-mentioned in-vehicle business slices, and may also be in-vehicle business slices with other names or types.

There are different resource requirements for different types of business slices. The capability description information of the service slice may be used to indicate the first resource configuration information required by the service slice corresponding to the in-vehicle service data in the in-vehicle system. The first resource configuration information includes at least one of the following: computing resource information, storage resource information, transmission resource information, and service slice type information. The first resource configuration information can be understood as the description information of the resources required by the service slice in the in-vehicle system.

Wherein, the transmission resources included in the first resource configuration information may include the corresponding security encryption information required by the service slice in the entire in-vehicle system, the slice transmission identifier, the transmission path corresponding to the service data to be transmitted in the service slice, and Quality of service (QoS) requirements such as bandwidth, delay, packet loss rate, and reliability required on the transmission path. The computing resources included in the first resource configuration information may include central processing unit (CPU) resources and the like required by the service slice in the entire in-vehicle system. The storage resources included in the first resource configuration information may include the size of storage space required by the service slice in the entire in-vehicle system, and so on.

The slice management module uniformly configures resources for at least one module in the in-vehicle system. Therefore, the slice management module obtains the capability description information of the service slice. The in-vehicle system includes at least one of the following modules: a data collection module, a data forwarding module, an in-vehicle business processing module, and an execution module. For example, in non-urban areas, it is necessary to expand the data collected by cameras, sensors, and radars required for autonomous driving and enhance the corresponding processing capabilities to adapt to the car-free environment, then the slice management module obtains the autonomous driving business corresponding to the in-vehicle business data Slice the first resource configuration information required in the in-vehicle system. For another example, the human-computer interaction system application layer program entertainment service temporarily calls on-board camera data, and the slice management module obtains the first resource configuration information required in the in-vehicle system for the in-vehicle entertainment business slice corresponding to the in-vehicle business data.

Wherein, the type information of the aforementioned service slice may be the identifier of the service slice, that is, the identifier of the service slice may be used to identify the type of the service slice. Of course, the type information of the service slice may also be expressed in other ways, for example, the service type name of the service slice is used to indicate the type of the service slice.

Optionally, in some embodiments, before the slice management module obtains the capability description information of the service slice, the data collection module sends the service attributes of the in-vehicle service data, and accordingly, the slice management module obtains the user-triggered or in-vehicle service processing The business attributes of the in-vehicle business data triggered by the module; the slice management module obtains the capability description information of the business slices according to the business attributes of the in-vehicle business data. The business attribute of the business data in the vehicle may be the transmission or processing requirements of the business data.

In specific implementation, the slice management module can obtain the capability description information of the business slice based on external requirements or internal requirements. The external demand is, for example, the business attribute of the in-car business data triggered by the user through the human-computer interaction page. The internal demand can be triggered by the in-vehicle business processing module according to its own algorithm to trigger the business attributes of in-vehicle business data. The in-vehicle business processing module obtains the business attributes of the in-vehicle business data triggered externally or internally, sends the business attributes of the in-vehicle business data to the data forwarding module, and sends it to the slice management module via the data forwarding module and/or the data gateway. In the process of sending the business attribute of the business data in the vehicle, the type information of the business slice can also be carried. The slice management module obtains the capability description information of the business slice according to the business attributes of the real-time in-vehicle business data.

S102. The slice management module obtains at least one piece of second resource configuration information according to the capability description information of the service slice.

The slice management module divides the various resources of the in-vehicle system, and realizes the isolation of resource configuration among multiple business slices. And according to the capability description information of each service slice, that is, according to the first resource configuration information required by the service slice in the in-vehicle system corresponding to the in-vehicle service data, at least one second resource configuration information corresponding to the service slice is acquired. The at least one piece of second resource configuration information includes at least one of the following: computing resource information, storage resource information, transmission resource information, and service slice type information.

Illustratively, take the capability description information of the autonomous driving slice as an example:

In the entire in-vehicle system, the transmission resource included in the first resource configuration information is a bandwidth of 10MB, the computing resource is a reserved 40% CPU computing resource, and the storage resource is a memory space of 8GB.

The slice management module obtains at least one piece of second resource configuration information according to the capability description information of the service slice, which may be:

Module 1, the transmission resource included in the second resource configuration information is 10MB bandwidth.

Module 2, the transmission resource included in the second resource configuration information is a bandwidth of 10MB, the computing resource is a 40% reserved CPU computing resource, and the storage resource is a memory space of 8GB.

The module 1 and module 2 can be any module in the in-vehicle system corresponding to the autonomous driving slice.

S103a to S103e: The slice management module sends at least one piece of second resource configuration information to the corresponding module.

Correspondingly, each module in the in-vehicle system receives the second resource configuration information. The second resource configuration information is one of the aforementioned at least one second resource configuration information.

During specific implementation, the slice management module sends the acquired at least one piece of second resource configuration information to the corresponding module in the in-vehicle system. That is, the slice management module sends the second resource configuration information corresponding to the data collection module to the data collection module; sends the second resource configuration information corresponding to the data forwarding module to the data forwarding module; and configures the second resource configuration corresponding to the in-vehicle business processing module The information is sent to the in-vehicle business processing module; and the second resource configuration information corresponding to the execution module is sent to the execution module. Optionally, if the in-vehicle system further includes one or more data gateways, the second resource configuration information corresponding to the data gateway is sent to the data gateway.

S104. Each module in the in-vehicle system obtains at least one resource required for transmission or processing of service data in the service slice according to the corresponding second resource configuration information. The at least one resource includes: computing resources, storage resources, and transmission. Resources.

Each module in the in-vehicle system obtains at least one resource required for the transmission or processing of service data in the service slice according to the corresponding second resource configuration information, that is, at least one resource included in the second resource configuration information by each module Assigned to the business slice. For example, in non-urban areas, it is necessary to expand the data collected by cameras, sensors, and radars required for autonomous driving and enhance the corresponding processing capabilities to adapt to the car-free environment. Then the in-vehicle service processing module reserves 40% of the CPU computing resources of the in-vehicle system for use by the autonomous driving service slices according to the computing resources included in the second resource configuration information; and according to the storage resources included in the second resource configuration information, The 8GB of memory space of the in-vehicle system is reserved for the automatic driving service slice; and according to the transmission resources included in the second resource configuration information, 60% or 50MB of the bandwidth is reserved for the automatic driving service slice.

According to a resource configuration method for in-vehicle service slices provided by an embodiment of the present application, the slice management module obtains the first resource configuration information required in the in-vehicle system according to the service slice corresponding to the in-vehicle service data in the in-vehicle system. The at least one second resource configuration information corresponding to the at least one module is sent to at least one module in the in-vehicle system, and each module in the in-vehicle system obtains the service data transmission and/or processing station according to the corresponding second resource configuration information. The required resources can realize the resource allocation and isolation between the business slices in the car, and meet different business needs.

Please refer to FIG. 5, which is a schematic flow diagram of another method for resource allocation of in-vehicle business slicing provided by an embodiment of this application. Illustratively, the method includes the following steps:

S201: The slice management module obtains the capability description information of the service slice. The capability description information of the service slice is used to indicate the first resource configuration information required by the service slice corresponding to the in-vehicle service data in the in-vehicle system.

For the specific implementation of this step, refer to step S101 of the embodiment shown in FIG. 4.

S202: The data collection module sends an access request to the data gateway, where the access request includes the identification of the data collection module and the type information of the service slice.

Correspondingly, the data gateway receives the access request.

The difference between this embodiment and the foregoing embodiments is that the slice management module is triggered to acquire at least one second resource configuration information of the service slice when the access request sent by the data collection module is received.

Assuming that the access control module communicates with other modules through the data gateway, the data collection module sends an access request to the data gateway. The access request includes the identification of the data collection module and the type information of the service slice.

It is understandable that the data collection module can access one or more service slices. Therefore, the access request includes the identification of the data collection module and the type information of one or more service slices. Taking the data acquisition module as a sensor as an example, the data acquisition module is a fusion senor. A fusion sensor refers to a sensor that integrates multiple sensor functions, such as supporting advanced driving assistance system (advanced driving assistance system, ADAS) sliced camera overlay supporting gas concentration sensor functions.

S202a. Optionally, if the in-vehicle system does not include a data gateway, the data collection module sends an access request to the access control module, where the access request includes the identification of the data collection module and the type information of the service slice.

S203. The data gateway sends an access request to the access control module, where the access request includes the identifier of the data collection module and the type information of the service slice.

After the data gateway obtains the access request sent by the data collection module, it forwards the access request to the access control module.

S204. The access control module determines whether to allow the data collection module to access the requested network slice.

The access control module can control the access of the data acquisition module. This step is optional. The figure is represented by a dotted line.

The corresponding relationship between the ID of the data collection module and the accessible network slice can be stored in the access control module, as shown in Table 1 below:

Table 1

数据采集模块的类型Type of data acquisition module	车内业务切片的类型Types of business slices in the car
Sensor ID-1Sensor ID-1	Slice ID-1Slice ID-1
