Description

Resource allocation method, device and system for service slices in vehicle

Technical Field

The application relates to the field of vehicle networking, in particular to a resource configuration method, device and system for service slices in a vehicle.

Background

The in-vehicle system provides the functions of safety, entertainment, energy conservation and the like for the vehicle. At present, an in-vehicle system bears different service requirements through different bus standards, different Electronic Control Units (ECUs) respectively complete own missions when in work, and exchange data and control commands through different data network protocols. With the rapid development of in-vehicle electronic systems, the number of in-vehicle ECUs, the demand for computing power, and the demand for communication bandwidth have increased substantially. Therefore, future in-vehicle systems will evolve in the following directions: the single ECU can be responsible for multiple requirements, centralization of computing capability and storage resources in the automobile and unification of hardware used by buses in the automobile.

However, although the in-vehicle systems have evolved in the above direction, it is necessary to guarantee the computing resources, storage resources and transmission resources required for the respective in-vehicle services, i.e. to achieve isolation of the above resources on the types of different in-vehicle services.

Existing fifth generation (5) ^th generation, 5G) the network slicing technique of mobile communication systems is a method for isolating transmission resources. The 5G network slicing technology provides mutually isolated network environments for different application scenarios in a manner of virtual independent logic networks on the same network infrastructure, so that different application scenarios can customize network functions and characteristics according to respective requirements, and quality of service (QoS) requirements of different services can be practically guaranteed. The 5G network slice is to organically combine terminal equipment, access network resources, core network resources, a network operation and management system and the like, and provide complete networks which can be independently operated and maintained and are mutually isolated for different business scenes or service types.

Fig. 1 is a schematic diagram of a conventional 5G network slice, which includes an enhanced mobile broadband (eMBB) slice, an ultra-reliable low-latency communication (URLLC) slice, and a large-scale internet of things (internet of things) slice. Since in the 5G mobile network architecture, the terminal device is a data input end, the application server of the service layer is a data processing end, and both the terminal device and the application server of the service layer are non-operator controlled, the 5G network slice mainly focuses on the slice of network transmission between the terminal and the gateway (as the dashed box in fig. 1), and does not involve the terminal and the service processing capability. The in-vehicle system is a closed and end-to-end complete system, and not only comprises a data input module such as a sensor, but also comprises a data processing module such as an automatic driving platform. Therefore, the in-vehicle system needs to slice not only on the transmission resource but also on the computing resource and the storage resource.

Therefore, the existing 5G slicing technology is not completely fit with the requirements of the in-vehicle system, and an end-to-end resource configuration scheme of the in-vehicle service slices needs to be designed, so that resource configuration and isolation among the in-vehicle service slices are realized, and different service requirements are met.

referring to fig. 4, a flow chart of a resource allocation method for an in-vehicle service slice according to an embodiment of the present application is schematically shown, where the method exemplarily includes the following steps:

s101, the slice management module acquires capability description information of the service slice, wherein the capability description information of the service slice is used for indicating first resource configuration information, required by the service slice in the in-vehicle system, corresponding to the in-vehicle service data.

In the embodiment, the in-vehicle network environment isolated from each other is provided for different service application scenes in a manner of virtualizing the independent logic network on a uniform hardware resource, so that the network functions and characteristics of different service application scenes can be customized according to respective requirements, and the service quality requirements of different services can be practically guaranteed. Specifically, the in-vehicle services include the following types of service slices: the system comprises an automatic driving business slice, an in-vehicle entertainment business slice, a vehicle body safety control business slice and the like.

Illustratively, the functions provided by the autopilot service slice, the in-vehicle entertainment service slice, and the body safety control service slice are described separately as follows:

Automatic driving business slicing: the safety level is high, strong software and hardware technical support is needed, and an integrated intelligent network is formed under the mutual cooperation of various sensors (such as a binocular camera and a three-dimensional laser scanning radar). For example: automatic driving functions such as an autonomous cruise system, remote garage parking, safe automatic following of a preceding vehicle under the condition of traffic congestion and the like all belong to the scope of the slice, so that resources occupied by data transmission of the automatic driving business slice need to be guaranteed urgently. It should be noted that the names of the above types of the automatic driving service slices are only examples, and other representations may also be used, such as driving service slices, intelligent driving service slices, and so on.

Slicing the in-vehicle entertainment business: the safety level is low, the entertainment system is mainly used for a driver to enjoy entertainment, functions such as a multimedia system, a radio and the like can be divided into the category of the slices, and data transmission resources required by the in-vehicle entertainment slices can be lower than those of the in-vehicle safety control slices. It should be noted that the names of the in-vehicle entertainment service slices are only examples, and other representations such as entertainment service slices, smart entertainment service slices, and the like can also be used.

Slicing safety control business of the vehicle body: the safety level is middle, the overall comfort and safety of the vehicle are guaranteed, and the vehicle enters a system, enters a trunk, a window or a roof locking system and then enters an illumination control system and can be divided into the slice category. The data transmission resources required for the body safety control slice may be lower than the autopilot service slice. It should be noted that, the names of the foregoing car body safety control service slices are only examples, and other representation manners, such as car body control slices, intelligent car body safety service slices, and the like, may also be used.

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

There are different resource requirements for different types of traffic slices. The capability description information of the service slice can be used for indicating 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: computing resource information, storing resource information, transmitting resource information, and type information of the service slice. The first resource configuration information may be understood as description information of resources required by the service slice in the in-vehicle system.

The transmission resource included in the first resource configuration information may include corresponding security encryption information required by the service slice in the whole in-vehicle system, a slice transmission identifier, a transmission path corresponding to service data to be transmitted in the service slice, and quality of service (QoS) requirements such as bandwidth, delay, packet loss rate, reliability, and the like required on the transmission path. The computing resource included in the first resource configuration information may include a Central Processing Unit (CPU) resource and the like required by the service slice in the whole in-vehicle system. The storage resource included in the first resource configuration information may include a storage space size required by the service slice in the entire in-vehicle system, and the like.

The slice management module performs resource allocation on at least one module in the in-vehicle system in a unified manner, so that the slice management module acquires capability description information of the service slice. The in-vehicle system comprises at least one of the following modules: the system comprises a data acquisition module, a data forwarding module, an in-vehicle service processing module and an execution module. For example, in a non-urban area, data acquired by a camera, a sensor and a radar required for automatic driving needs to be expanded and corresponding processing capacity needs to be enhanced so as to adapt to an environment without a vehicle networking, and then the slice management module acquires first resource configuration information required by an automatic driving service slice corresponding to service data in a vehicle system. For another example, when the entertainment service of the application layer program of the human-computer interaction system temporarily calls the data of the vehicle-mounted camera, the slice management module acquires first resource configuration information, required by the in-vehicle entertainment service slice corresponding to the in-vehicle service data, in the in-vehicle system.

The type information of the service slice may be an 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 other representation manners, for example, the service type name of the service slice is used to represent 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 acquisition module sends a service attribute of the in-vehicle service data, and accordingly, the slice management module obtains the service attribute of the in-vehicle service data triggered by the user or triggered by the in-vehicle service processing module; and the slice management module acquires the capability description information of the service slice according to the service attribute of the service data in the vehicle. The service attribute of the in-vehicle service data may be a transmission or processing requirement of the service data.

In specific implementation, the slice management module may obtain the capability description information of the service slice based on external requirements or internal requirements. The external requirements are, for example, business attributes of the in-vehicle business data triggered by the user through the human-computer interaction page. The internal requirements can be triggered by the in-vehicle service processing module according to the service attributes of the in-vehicle service data. The in-vehicle service processing module acquires the service attribute of the externally or internally triggered in-vehicle service data, sends the service attribute of the in-vehicle service data to the data forwarding module, and sends the service attribute of the in-vehicle service data to the slice management module through the data forwarding module and/or the data gateway. And in the process of sending the service attribute of the service data in the vehicle, the type information of the service slice can be carried. And the slice management module acquires the capability description information of the service slice according to the real-time service attribute of the service data in the vehicle.

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

The slice management module divides various resources of the in-vehicle system, and realizes the isolation of resource allocation among a plurality of service slices. And acquiring at least one second resource configuration information corresponding to each service slice according to the capability description information of each service slice, namely according to first resource configuration information, required by the service slice in the in-vehicle system, corresponding to the in-vehicle service data. The at least one second resource configuration information includes at least one of: computing resource information, storing resource information, transmitting resource information, and type information of the service slice. The at least one second resource configuration information corresponds to the type of the service slice, and the at least one second resource configuration information corresponds to at least one module in the in-vehicle system one to one. The second resource configuration information may be understood as a configuration scheme of the slice management module for the resource.

The transmission resource included in the second resource configuration information may include security encryption information corresponding to at least one service slice required by at least one module related to the in-vehicle system service slice, a slice transmission identifier, a transmission path corresponding to service data to be transmitted in the service slice, and service quality requirements such as bandwidth, time delay, packet loss rate, reliability and the like required on the transmission path. The second resource configuration information may include computing resources including central processing unit resources required for the runtime of at least one module involved in the in-vehicle business slice, and so on. The second resource configuration information may include a storage resource including a size of a storage space required by at least one module related to the in-vehicle system service slice, and the like.

When the service data is transmitted in different modules or data gateways in the service slice, a plurality of slice transmission identifiers can be adopted, and the plurality of slice transmission identifiers correspond to the same type of the service slice.

Illustratively, the capability description information of the autopilot slice is used as an example:

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

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

in block 1, the second resource allocation information includes transmission resources with a bandwidth of 10 MB.

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

The module 1 and the module 2 may be any module in an in-vehicle system corresponding to an automatic driving slice.

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

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

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

S104, each module in the in-vehicle system acquires at least one resource required by the service data for transmission or processing in the service slice according to the corresponding second resource configuration information, wherein the at least one resource comprises: computing resources, storage resources, transmission resources.

Each module in the in-vehicle system acquires at least one resource required for transmission or processing of the service data in the service slice according to the corresponding second resource configuration information, that is, each module allocates at least one resource included in the second resource configuration information to the service slice. For example, in non-urban areas, the capacity of data collected by a camera, a sensor and a radar required by automatic driving needs to be expanded, and corresponding processing capacity needs to be enhanced, so that the non-vehicle networking environment is adapted. The in-vehicle service processing module reserves 40% of CPU (central processing unit) computing resources of the in-vehicle system for the automatic driving service slice according to the computing resources included in the second resource configuration information; reserving 8GB memory space of the in-vehicle system for the automatic driving business slice according to the storage resources included by the second resource configuration information; and reserving 60% or 50MB of bandwidth for the automatic driving traffic slice to use according to the transmission resource included in the second resource configuration information.

According to the resource allocation method for the service slices in the vehicle, the slice management module acquires at least one piece of second resource allocation information corresponding to at least one module in the vehicle interior system according to first resource allocation information, required by the service slices corresponding to the service data in the vehicle interior system, of the service slices in the vehicle interior system and sends the second resource allocation information to the at least one module in the vehicle interior system, and each module in the vehicle interior system acquires resources required by service data transmission and/or processing according to the corresponding second resource allocation information, so that resource allocation and isolation among the service slices in the vehicle interior can be realized, and different service requirements are met.

Referring to fig. 5, a schematic flowchart of a resource allocation method for a service slice in a vehicle according to another embodiment of the present application is shown, where the method exemplarily includes the following steps:

s201, the slice management module acquires capability description information of the service slice, wherein the capability description information of the service slice is used for indicating first resource configuration information, required by the service slice corresponding to the service data in the vehicle, in the vehicle system.

The specific implementation of this step can refer to step S101 in the embodiment shown in fig. 4.

S202, the data acquisition module sends an access request to the data gateway, wherein the access request comprises the identification of the data acquisition module and the type information of the service slice.

Accordingly, the data gateway receives the access request.

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

Assuming that the access control module communicates with other modules through the data gateway, the data acquisition module sends an access request to the data gateway, where the access request includes an identifier of the data acquisition module and type information of a service slice.

It will be appreciated that the data collection module may access one or more service slices, and thus, the access request includes an identification of the data collection module and type information for the one or more service slices. Taking the example that the data acquisition module is a sensor (sensor), the data acquisition module is a fused sensor. The merged sensor refers to a sensor that integrates various sensor functions, such as a function of supporting an Advanced Driving Assistance System (ADAS) slice camera overlay supporting a gas concentration sensor.

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

S203, the data gateway sends an access request to the access control module, wherein the access request comprises the identification of the data acquisition module and the type information of the service slice.

And after acquiring the access request sent by the data acquisition module, the data gateway forwards the access request to the access control module.

S204, the access control module judges whether the data acquisition module is allowed to access the requested network slice.

The access control module can control the access of the data acquisition module. This step is an optional step. Indicated by dashed lines in the figure.

The access control module may store a correspondence between the identifier of the data acquisition module and the accessible network slice, as shown in table 1 below:

TABLE 1

Type of data acquisition Module	Type of business slice in vehicle
		Sensor ID-1	Slice ID-1
