In order to facilitate those skilled in the art to understand the technical solutions provided in the embodiments of the present application, the following description is provided for the related technologies:

private networks are private networks that provide network communication services to specific users, for which it has been predicted that the global private 5G market will scale to $ 9.197 billion in 2020, that the composite annual growth rate between 2020 and 2027 will reach 37.8%, and that north america will dominate the private 5G market with a 31.2% share. Currently, the system architecture of the 5G private network on the market is defined by 3GPP (e.g. 38.300), as shown in fig. 1, 5GC and RAN are deployed in a distributed manner, and message and data interaction is performed through network transmission.

As for the system architecture of the above-mentioned 5G private network, corresponding to a software architecture for implementing data transmission operation, referring to fig. 2, an access and mobility management function AM in the architecture is mainly responsible for functions of registration management, mobility, reachability management, and the like of a user; the session Management Function SMF is responsible for session Management, Selection and Control of a user plane Function UPF, IP address allocation and Management, Unified Data Management (UDM) is responsible for Unified processing of foreground Data, an Authentication Server Function (AUSF) cooperates with UDM to complete user Authentication, UPF completes routing and forwarding functions of user plane Data, a Policy Control Function (PCF) provides policy rules for a Control plane, and a Network Slice Selection Function (NSSF) is used to manage information related to Network slices.

In some scenes of a private network, a set of 5G system can cover 1-4 cells, and at this time, one core network and one base station can meet the requirement, however, since the core network (5 GC) and the base station in the 5G system are often deployed independently, a large resource overhead is needed between the core network and the base station.

For example, the core network and the base station perform a control plane transmission operation through a Next Generation Application Protocol (NGAP) and a transmission Protocol SCTP for 5GC and a control plane message of the base station, and perform a data plane transmission through GTP-u. As can be seen from the above, the core network in the communication system is an independent system, and has a control plane and a data plane, and the control plane can manage the data plane. Similarly, a base station in a communication system is a stand-alone system having a control plane and a data plane, where the control plane can manage the data plane.

Because the core network and the base station are two independent systems, the network transmission and the network packet protocol processing between the 5GC and the base station need great resource information, so that the required network resource information is increased, the software logic complexity is higher, the resource occupation is more, the operation and maintenance complexity of the network is improved, the investment cost CAPEX and the operation and maintenance cost OPEX are also increased, and the user experience is reduced.

In order to solve the above technical problem, the present embodiment provides a data communication system, a method, a live data transmission method, a device and an apparatus, where, referring to fig. 3, the data communication system may include: a control plane and a user plane (corresponding to a data plane), wherein the control plane may be a control plane of a private network or a control plane of a public network, and the user plane may be a user plane of the private network or a user plane of the public network. In addition, the control plane and the user plane may be communicatively connected through a preset interface Nx, where the preset interface may be a defined new interface, and is used to replace an E1 interface and an N4 interface that are used for communicatively connecting between a previous core network and a base station, where the core network may be a 5G core network or a 6G core network, and the base station may be a 5G base station or a 6G base station.

It should be noted that the number of the control plane and the user plane in the communication system is 1, that is, the core network and the base station share one control plane and one user plane. At this time, in order to improve the operation stability and reliability of the communication system, the control plane includes a control logic and a data communication logic for controlling the user plane; wherein the policing logic may include at least one of: the core network is in communication connection with the base station, and the base station can be connected with one or more user terminals to realize network connection operation of the user terminals.

And the user plane comprises a data Packet Routing network element IP Packet Routing which is in communication connection with the data network server, and the data Packet Routing network element is used for realizing data processing operation under the control of the control logic and the data communication logic.

In some examples, the core network may be communicatively connected to one or more base stations, and when the core network is communicatively connected to the plurality of base stations, the core network and the plurality of base stations may perform fusion or integrated operation, at this time, the core network and the plurality of base stations may share one control plane and one user plane, and at this time, the control plane may include control logics corresponding to all the base stations, a base station identity identifier, and a control logic of the core network, thereby improving applicability of the communication system.

The technical solution provided in this embodiment effectively implements a fusion (or integration) operation of the core network and the base station, which is beneficial to implementing an integrated operation of the communication system, specifically, in terms of a logical architecture, the core network and the base station share the same control plane and user plane, that is, the control plane fuses the control logic and data communication logic of the core network and the base station, and completes a forwarding operation of a data packet based on the control logic and data communication logic and by using a newly defined packet routing network element in the user plane, thereby implementing a data transmission operation by using the communication system, and further improving the practicability of the communication system.

The following describes a data communication system, a data communication method, a live data transmission device, and a live data transmission device, provided by various embodiments of the present application, in detail through an exemplary application scenario. The features of the embodiments and examples described below may be combined with each other without conflict between the embodiments.

Fig. 4 is a schematic structural diagram of a data communication system according to an embodiment of the present application; referring to fig. 4, the present embodiment provides a simplified and novel data communication system, which may be implemented as a network server, a board card, a circuit board, and the like, and the data communication system may be applied to an application scenario of a 5G private network, an application scenario of a 5G public network, an application scenario of a 6G private network, an application scenario of a 6G public network, and the like. Specifically, the data communication system may include:

control planes (corresponding to 5G control plane, 6G control plane) including policing logic for implementing control of the user plane and data communication logic, wherein the policing logic may include at least one of: the first management logic of the core network and the second management logic of the base station may include, in some examples, the first management logic of the core network and the second management logic of the base station, where the first management logic and the second management logic are different. Similarly, the data communication logic may include at least one of: a first data communication logic of a radio resource control network element RRC and a second data communication logic of a network attached storage NAS signaling. In some examples, the data communication logic may include: a first data communication logic of a radio resource control network element RRC and a second data communication logic of a network attached storage NAS signaling.

In addition, the core network in the above embodiment is communicatively connected to the base station, and it should be noted that in different application scenarios, the core network and the base station are of different types, for example: in the application scenario of 5G, the core network is a 5G core network, and the base station is a 5G base station; in the application scenario of 6G, the core network is a 6G core network, and the base station is a 6G base station. No matter what type of base station, the base station may be connected with one or more ues to implement network connection operation of the ues.

The user plane (corresponding to the 5G user plane, the 5G data plane, the 6G user plane, and the 6G data plane) is communicatively connected to the control plane through a preset interface Nx, which may be a defined new interface, and is used to replace an E1 interface and an N4 interface for communicatively connecting between the core network and the base station in the historical architecture. In addition, in order to implement stable heating transmission operation on data, the user plane may include a Packet Routing network element IP Packet Routing communicatively connected to the data network server, where the Packet Routing network element is configured to implement data processing operation under the control of the control logic and the data communication logic.

The packet routing network element may be in communication connection with the data network server through an N6 interface or other preset interfaces Ny, as long as stable communication connection between the packet routing network element and the data network server can be ensured, which is not described herein again.

Specifically, when implementing data processing operation based on the packet routing network element, an implementable manner may include: acquiring a data packet to be forwarded, and establishing a session message corresponding to the data packet under the control of the control logic and the data communication logic; determining a hash table corresponding to the session message, wherein the hash table comprises a destination address corresponding to the session message; and forwarding the data packet by using the data packet routing network element and the hash table.

In still other implementations, implementing the data processing operation based on the packet routing network element may include: acquiring a data packet to be forwarded, establishing session information corresponding to the data packet under the control of control logic and data communication logic, determining a forwarding address based on the session information, a destination address corresponding to the data packet and a network architecture of a communication system, and sending the data packet to the forwarding address by using a data packet routing network element so as to finally send the data packet to the destination address.

Any one of the above implementation manners effectively realizes the data forwarding operation through the data packet routing network element under the control of the management and control logic and the data communication logic, and ensures the stable reliability of data transmission in the communication system.

In some examples, to enable normal operation of the network, the user plane in this embodiment may include: a physical layer PHY entity, a medium access control layer MAC entity, a radio link control layer RLC entity and a packet data convergence protocol PDCP entity.

The PHY entity is used for establishing, maintaining and disconnecting physical connection; the MAC entity defines how data is transmitted over the medium; the RLC entity is used for controlling the wireless link and providing a reliable link independent of a wireless solution; the PDCP entity is configured to implement data transmission and reception operations, and the content may include IP addresses of users that transmit and receive data. Through the entities configured on the user plane, normal data communication operation of the user in a communication network is effectively realized, and the stable reliability of the application of the communication system is further ensured.

In the data communication system provided in this embodiment, the control plane is configured to include a control logic and a data communication logic for controlling the user plane, and a newly established data packet routing network element in the user plane is used to perform data processing operation, so that the fusion (or integration) operation of the core network and the base station is effectively realized, which is favorable for realizing the integrated operation of the communication system; specifically, in a logic architecture, the core network and the base station share the same control plane and user plane, that is, the control plane integrates the control logic and the data communication logic of the core network and the base station, and the forwarding operation of the data packet is completed based on the control logic and the data communication logic and by using a newly defined data packet routing network element in the user plane, so that the data transmission operation by using the communication system is realized, the practicability of the communication system is further improved, and the popularization and the application in the market are facilitated.

On the basis of the foregoing embodiment, as shown in fig. 4 with continued reference to fig. 4, in the process of performing data transmission by using the communication system, because the existing 5G communication architectures all meet the third Generation Partnership Project (3 rd Generation Partnership Project, 3 GPP) specification, and the 3GPP specification defines NG-AP (NG interface) and Network Attached Storage (NAS) signaling of SCTP bearer N2, and because SCTP is a stateful transport layer protocol, the difficulty of introducing SCTP by the cloud platform is large, and many open source components need to be additionally developed to support, thereby increasing the complexity of Network maintenance.

In order to reduce the complexity of network maintenance, the packet routing network element in this embodiment may include processing logic corresponding to each of a user plane function UPF network element and a service data adaptation protocol SDAP layer entity.

Specifically, as shown in fig. 5, the User Plane Function (UPF) of the core network is used to implement packet routing forwarding, policy enforcement, traffic reporting, and Qos processing, and when the packet routing network element includes processing logic corresponding to the UPF network element, the packet routing network element may also implement operations such as packet routing forwarding, policy enforcement, traffic reporting, and Qos processing. Similarly, the functions that the SDAP is capable of implementing may include, but are not limited to: the mapping module is configured to process mapping from a QoS flow to a Data Resource Bearer (DRB for short), and when the packet routing network element includes processing logic corresponding to the SDAP, the packet routing network element can also process mapping from the QoS flow to the DRB.

In some examples, when the user plane includes the packet routing network element, since the packet routing network element may include processing logic corresponding to each of the user plane function UPF network element and the service data adaptation protocol SDAP layer entity, in order to simplify the user plane, the UPF and the SDAP in the user plane may be further deleted, that is, services of the UPF and the SDAP in the user plane are merged and replaced by the packet routing network element.

In this embodiment, the data packet routing network element in the user plane is configured to include processing logics corresponding to the user plane function UPF network element and the service data adaptation protocol SDAP layer entity, which is beneficial to implementing the fusion operation of the core network and the base station, and can ensure that the data processing logics and the control logics of the core network and the base station remain unchanged, thereby being beneficial to simplifying the user plane.

In still other examples, since signaling interaction between a core network and a base station defined by the 3GPP specification for maintaining an SCTP link requires an IP network, not only the maintenance complexity is increased, but also the maintenance operation of the user is not friendly enough, in order to solve the above problem that "the maintenance complexity is increased, and the operation and maintenance are not friendly enough", the control plane in this embodiment may include an AMF network element, and the AMF network element and the base station are in communication connection through an inter-process communication mechanism.

It should be noted that, referring to fig. 6, the Control plane may include not only the AMF network element, but also a Radio Resource Control (RRC) network element and an SMF network element, where the RRC network element may perform Radio Resource management, Control and scheduling through a preset policy and means; the SMF network element is used for tunnel maintenance, IP address allocation and management, UP function selection, policy enforcement, QoS control, charging data acquisition, roaming and other operations.

In this embodiment, the core network and the base station may be communicatively connected through an inter-process communication mechanism, and specifically, the core network and the base station may be communicatively connected in a manner of sharing content and message queues.

The control plane comprises a mobility management function AMF network element, and the AMF network element is in communication connection with the base station through an interprocess communication mechanism. Specifically, since the AMF network element in the control plane and the base station may be communicatively connected through an inter-process communication mechanism, signaling interaction between the AMF network element and the base station may be carried through inter-process communication (IPC), for example: the signaling interactive operation can be realized by sharing the memory and the message queue, so that not only can the network resource overhead and the complexity of software logic be reduced, but also the communication efficiency between the base station and the core network can be improved, and the quality and the efficiency of data transmission are further improved.

In other examples, for a communication system, GTP-u is a tunneling Protocol for user plane packet transmission between a core network and a base station, when the user plane packet is transmitted, the base station and a UPF network element in the core network need to perform GTP encapsulation and decapsulation operations on the packet, which results in a large overhead of network resources in the process, and the core network and the base station also need to maintain mapping between a tunnel endpoint identifier TEID and a Protocol Data Unit (PDU for short) session, which increases complexity of software logic.

Since the core network and the base station may be communicatively connected through an inter-process communication mechanism, in order to reduce the complexity of software logic corresponding to the communication system, the base station communicatively connected to the packet routing network element in this embodiment does not include data processing logic for implementing encapsulation or decapsulation of data.

Specifically, in order to enable the base station not to include the data processing logic for implementing encapsulation or decapsulation of the data, the base station communicatively connected to the packet routing network element may be configured to not include: a tunneling protocol GTP-u entity for realizing user plane data transmission between the core network and the base station, a transmission protocol SCTP entity for realizing control plane messages between the core network and the base station, an Internet protocol IP entity, and the same physical layer L1 entity/data link layer L2 entity.

Specifically, referring to fig. 5, the existing communication system may include a tunneling protocol GTP-u entity for implementing user plane data transmission between the core network and the base station, a transport protocol SCTP entity for implementing control plane messages between the core network and the base station, an internet protocol IP entity, the same physical layer L1 entity/data link layer L2 entity, since the UPF only performs the forwarding operation of the IP packet, the GTP-U encapsulation or decapsulation operation of the data packet from the external network (N6) or the base station L2 is not required, in this embodiment, the base station and the core network in the communication system may perform data transmission operation through an inter-process communication mechanism, and at this time, the above entities do not need to be utilized again to perform GTP encapsulation and decapsulation operations on the data packet, and the shaded part in the figure can be omitted.

FIG. 15 is a schematic flow chart illustrating a method for controlling a vehicle according to an embodiment of the present disclosure; referring to fig. 15, the embodiment provides a vehicle control method, and the execution subject of the method may be a vehicle control device, it is understood that the vehicle control device may be implemented as software, or a combination of software and hardware, and when implemented specifically, the vehicle control device may be deployed in a 4G network, a 5G network, or a 6G network to implement a control operation on a vehicle. Specifically, the vehicle control method may include:

step S1501: a vehicle control request corresponding to a vehicle is obtained.

Step S1502: driving path planning information corresponding to the vehicle control request is determined.

Step S1503: and forwarding the driving path planning information to the vehicle by using a data packet routing network element in the user plane so as to control the vehicle based on the driving path planning information.

Specifically, in order to realize accurate and effective control of the vehicle during operation of the vehicle (unmanned vehicle or manned vehicle), a vehicle control request corresponding to the vehicle may be generated, where the vehicle control request may include operating state data and an IP address corresponding to the vehicle, specifically, a sensor may be disposed on the vehicle, and the operating state data corresponding to the vehicle may be acquired through the sensor, where the operating state data corresponding to the vehicle may include at least one of: the vehicle driving method comprises the steps of obtaining the current vehicle speed, the driving direction and the environment information of a vehicle, wherein the environment information comprises the distribution position of surrounding objects, the vehicle speed of the vehicle in front of the vehicle and the road speed limit of the road where the vehicle is located. In some examples, the sensors may include an image capture sensor, a radar sensor, and a global positioning system GPS, and in particular, the operating condition data corresponding to the vehicle may be determined by the image capture sensor, the radar sensor, and the global positioning system GPS.

After the vehicle control request is acquired, the driving path planning information may be determined based on the vehicle control request, specifically, the vehicle control request may be sent to a server of a preset network to determine and provide a vehicle control resource corresponding to the vehicle control request through the server, and then the vehicle control request may be analyzed based on the vehicle control resource to determine the driving path planning information corresponding to the vehicle control request, so that the driving path planning information corresponding to the vehicle control request may be obtained. Alternatively, a machine learning model for analyzing the running state data of the vehicle is previously configured, and the machine learning model is trained to determine driving path planning information corresponding to the vehicle. After the vehicle control request is acquired, the vehicle control request may be input to the machine learning model, so that driving path planning information corresponding to the vehicle control request may be obtained.

After the driving path planning information is obtained, the driving path planning information may be forwarded to the vehicle by using a packet routing network element in a user plane included in the vehicle control device, so as to control the vehicle based on the driving path planning information. It should be noted that, as for the vehicle control device, the vehicle control device may be provided on the vehicle, or the vehicle control device may be provided independently of the vehicle, in which case the vehicle control device may be communicatively connected to the vehicle CPU.

In addition, the vehicle control device can be adjusted according to different vehicles, that is, algorithm modules included in the vehicle control device are different according to different vehicle types, and in this case, the vehicle control device can implement not only the control operation of the automatic driving of the vehicle, but also other operations. For example, different vehicle control devices may be involved for a logistics vehicle, a public service vehicle, a medical service vehicle, and a terminal service vehicle. Algorithm modules included in the vehicle control device are exemplified below for the four kinds of autonomous vehicles, respectively:

wherein, the logistics vehicle refers to the vehicle that uses in the logistics scene, for example: the logistics vehicle with the automatic sorting function, the refrigeration and heat preservation function and the measurement function can be used. These logistics vehicles may involve different algorithm modules.

For example, the logistics vehicles can be provided with an automatic sorting device, and the automatic sorting device can automatically take out, convey, sort and store the goods after the logistics vehicles reach the destination. This relates to an algorithm module for goods sorting, which mainly implements logic control of goods taking out, carrying, sorting, storing and the like.

For another example, in a cold chain logistics scenario, the logistics vehicle may further include a refrigeration and insulation device, and the refrigeration and insulation device may implement refrigeration or insulation of transported fruits, vegetables, aquatic products, frozen foods, and other perishable foods, so that the transportation environment is in a proper temperature environment, and the long-distance transportation problem of perishable foods is solved. The algorithm module is mainly used for dynamically and adaptively calculating the proper temperature of cold meal or heat preservation according to the information such as the property, the perishability, the transportation time, the current season, the climate and the like of food (or articles), and automatically adjusting the cold-storage heat preservation device according to the proper temperature, so that a transport worker does not need to manually adjust the temperature when the vehicle transports different foods or articles, the transport worker is liberated from the complicated temperature regulation and control, and the efficiency of cold-storage heat preservation transportation is improved.

For another example, in most logistics scenarios, the fee is charged according to the volume and/or weight of the parcel, but the number of logistics parcels is very large, and the measurement of the volume and/or weight of the parcel by a courier is only dependent, which is very inefficient and has high labor cost. Therefore, in some logistics vehicles, a measuring device is added, so that the volume and/or the weight of the logistics packages can be automatically measured, and the cost of the logistics packages can be calculated. This relates to an algorithm module for logistics package measurement, which is mainly used to identify the type of logistics package, determine the measurement mode of logistics package, such as volume measurement or weight measurement or combined measurement of volume and weight, and can complete the measurement of volume and/or weight according to the determined measurement mode and complete the cost calculation according to the measurement result.

The public service vehicle refers to a vehicle providing some public service, for example: can be a fire truck, an ice removing vehicle, a watering cart, a snow shoveling vehicle, a garbage disposal vehicle, a traffic guidance vehicle and the like. These public service vehicles may involve different algorithm modules.

For example, in the case of an automatically driven fire fighting vehicle, the main task is to perform a reasonable fire fighting task on the fire scene, which involves an algorithm module for the fire fighting task, which at least needs to implement logic such as identification of the fire situation, planning of the fire fighting scheme, and automatic control of the fire fighting device.

For another example, for an ice removing vehicle, the main task is to remove ice and snow on the road surface, which involves an algorithm module for ice removal, the algorithm module at least needs to realize the recognition of the ice and snow condition on the road surface, formulate an ice removal scheme according to the ice and snow condition, such as which road sections need to be deiced, which road sections need not to be deiced, whether a salt spreading manner, the salt spreading gram number, and the like are adopted, and the logic of automatic control of a deicing device under the condition of determining the ice removal scheme.

The medical service vehicle is an automatic driving vehicle capable of providing one or more medical services, the vehicle can provide medical services such as disinfection, temperature measurement, dispensing and isolation, and the algorithm modules relate to algorithm modules for providing various self-service medical services.

The terminal service vehicle is a self-service automatic driving vehicle which can replace some terminal devices and provide certain convenient service for users, and for example, the vehicles can provide services such as printing, attendance checking, scanning, unlocking, payment and retail for the users.

For example, in some application scenarios, a user often needs to go to a specific location to print or scan a document, which is time consuming and labor intensive. Therefore, a terminal service vehicle capable of providing printing/scanning service for a user appears, the service vehicles can be interconnected with user terminal equipment, the user sends a printing instruction through the terminal equipment, the service vehicle responds to the printing instruction, documents required by the user are automatically printed, the printed documents can be automatically sent to the position of the user, the user does not need to queue at a printer, and the printing efficiency can be greatly improved. Or, the scanning instruction sent by the user through the terminal equipment can be responded, the scanning vehicle is moved to the position of the user, the user places the document to be scanned on the scanning tool of the service vehicle to complete scanning, queuing at the printer/scanner is not needed, and time and labor are saved. This involves an algorithm module providing print/scan services that needs to identify at least the interconnection with the user terminal equipment, the response to print/scan instructions, the positioning of the user's location, and travel control.

For another example, as new retail scenes are developed, more and more electronic stores sell goods to large office buildings and public areas by means of self-service vending machines, but the self-service vending machines are placed at fixed positions and are not movable, and users need to go by the self-service vending machines to purchase needed goods, so that the convenience is poor. Therefore, self-service driving vehicles capable of providing retail services appear, the service vehicles can carry commodities to move automatically and can provide corresponding self-service shopping APP or shopping entrances, a user can place an order for the self-service driving vehicles providing retail services through the APP or shopping entrances by means of a terminal such as a mobile phone, the order comprises names and numbers of commodities to be purchased, and after the vehicle receives an order placement request, whether the current remaining commodities have the commodities purchased by the user and whether the quantity is sufficient can be determined. This involves algorithm modules that provide retail services that implement logic primarily to respond to customer order requests, order processing, merchandise information maintenance, customer location, payment management, etc.
