[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on November 29, 2023, with application number 202311627129.0 and application name "A Communication System, Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of wireless communication technology, and in particular to a communication system, a communication method, and a device. Background Art

[0004] The fifth generation (5 th In 5G (5G) generation communications systems, network slicing technology has emerged to meet the varying quality of service (QoS) requirements of different industries, users, or businesses. Network slicing provides multiple dedicated, virtualized, and isolated logical networks on a shared infrastructure, each serving a specific business type or industry user. Each network slice can flexibly define its own logical topology, service level agreement (SLA) requirements, reliability, and security levels to meet the differentiated needs of different businesses or users.

[0005] For example, enhanced mobile broadband (eMBB) services have high requirements for transmission rates, massive machine type communication (mMTC) services require the network to support massive device access and the frequent transmission of large numbers of small messages, and ultra-reliable low latency communication (uRLLC) services require millisecond-level latency and high reliability. Therefore, eMBB services, mMTC services, and uRLLC services can use different network slices.

[0006] Therefore, 5G communication systems are based on network slicing and network function virtualization (NFV) technology to achieve network function customization for connecting services. thIn the 5G (6G) generation communication system, with the emergence of new services (new services that integrate artificial intelligence (AI) and communications), the current network function customization solutions in the 5G communication system will not be able to meet the needs of new services.

Optionally, connections are established between the multiple function instances included in the target network 11, and connections are established between the multiple function instances and at least one of the first core network device, the access network device, and the terminal device included in the target network.

[0174] It should be noted that the core network device in the embodiment of the present application can be a server or cloud platform that provides core network functions in the core network (exemplarily, the server or cloud platform provides background computing support for implementing various functions of the core network). The first core network device 113 included in the target network 11 in the embodiment of the present application can be one or more, and the multiple function instances included in the target network 11 can be deployed on the same first core network device 113, or the multiple function instances included in the target network 11 can be separately deployed on multiple first core network devices 113.

[0188] Optionally, the attribute information of the network function includes at least one of the following information:

[0189] Function name, function description information, function input information, function output information, configurable parameter types, and creation method instructions.

[0190] Among them, the first function management unit and the second function management unit can be deployed independently, or the first function management unit and the second function management unit can also be deployed in combination with other functions in the network architecture (for example, the first function management unit and the second function management unit are deployed in combination with the network repository function (NRF)).

[0191] It should be noted that the data processing unit 101, the network control unit 102, and the function management unit 103 included in the communication system 10 of the embodiment of the present application can be deployed on the same physical device, for example, the data processing unit 101, the network control unit 102, and the function management unit 103 can all be deployed in the core network device; or the data processing unit 101, the network control unit 102, and the function management unit 103 included in the communication system 10 of the embodiment of the present application can be deployed on different physical devices, for example, the data processing unit 101, the network control unit 102, and the function management unit 103 are respectively deployed on different physical devices, or two of the data processing unit 101, the network control unit 102, and the function management unit 103 can be deployed on the same entity, and the other unit is deployed on a different physical device. The embodiment of the present application does not limit the deployment method of the data processing unit 101, the network control unit 102, and the function management unit 103 included in the communication system 10.

[0192] In addition, the data processing unit 101, the network control unit 102 and the function management unit 103 included in the communication system 10 in the embodiment of the present application can all be implemented by software or hardware, and the embodiment of the present application does not limit this.

[0193] In the embodiments of the present application, the communication system 10 can create a corresponding target network based on service requirement information. When the service requirement information differs, the communication system 10 can create different target networks. Specifically, the communication system 10 can customize the core network's functionality based on service requirement information, or it can customize the core network, access network equipment, and terminal equipment's functionality based on service requirement information. The following describes each of these in conjunction with several specific system architectures.

[0194] A possible system architecture diagram applicable to an embodiment of the present application is shown in Figure 2. Take the system architecture shown in Figure 2 as an example, in which the function management unit 103 includes a first function management unit and a second function management unit; wherein the first function management unit stores multiple data processing-related application functions, and the second function management unit stores multiple connection-related network functions. Exemplarily, the multiple application functions stored in the first function management unit may include: perception imaging function, image question and answer function, face recognition function, target detection function, environment modeling function, path planning function, etc.; the multiple network functions stored in the second function management unit may include: querying neighboring base stations function, querying neighboring terminals function, data storage function, data privacy protection function, computing offloading function, data forwarding function, access function, etc.

[0195] The data processing unit 101 can obtain multiple application functions in the first function management unit and multiple network functions in the second function management unit, and select at least one first function and at least one second function configured for the target network from the multiple application functions and multiple network functions based on business demand information to generate first configuration information. After receiving the first configuration information from the data processing unit 101, the network control unit 102 creates at least one function instance in the network and establishes a connection between the function instances based on the at least one first function and at least one second function indicated by the first configuration information. If the first function is a core network function (wherein, in the embodiment of the present application, the core network function can be understood as a function performed by the first core network device), a first function instance corresponding to the first function is created in the core network, and if the second function is a core network function, a second function instance corresponding to the second function is created in the core network, and a connection is established between the function instances (including the first function instance and the second function instance), thereby achieving on-demand customization of the core network function. The network control unit 102 may also establish a connection between a function instance (including a first function instance and a second function instance) and the terminal device 111 and / or the access network device 112. For example, if the first function is a function of the core network and there is a dependency relationship between the first function and the function of the access network device 112, then after the core network creates the first function instance corresponding to the first function, a connection between the first function instance and the access network device 112 may be established. In addition, in the system architecture shown in FIG2 , the network control unit 102 may also perform function configuration on the access network device 112 and / or the terminal device 111 according to the first configuration information. For example, if the network control unit 102 determines that the first function indicated by the first configuration information is a function corresponding to the access network device 112, the network control unit 102 may perform corresponding function configuration on the access network device 112 and configure the first function for the access network device 112. If the network control unit 102 determines that the first function indicated by the first configuration information is a function corresponding to the terminal device 111, the network control unit 102 may perform corresponding function configuration on the terminal device 111 and configure the first function for the terminal device 111.

[0196] It should be noted that, based on the system architecture shown in FIG2 , when the communication system 10 creates a target network, the first and second functions of the core network can be customized according to the service requirement information, and the functions of the terminal device 111 and the access network device 112 can be configured accordingly according to the first configuration information. For example, the multiple application functions stored in the function management unit 1 and the multiple network functions stored in the function management unit 2 in FIG2 can be understood as functions of the core network.

[0197] A schematic diagram of a possible system architecture applicable to an embodiment of the present application is shown in FIG3 . The function management unit 103 in the system architecture shown in FIG3 may include multiple units. Exemplarily, FIG3 takes the function management unit 103 as an example, including four units, namely function management unit 1, function management unit 2, function management unit 3, and function management unit 4. Among them, function management unit 1 and function management unit 2 may correspond to the above-mentioned second function management unit, and are respectively used to store the network functions associated with the connection between the core network and the access network equipment. Exemplarily, the function management unit 1 may store multiple network functions of the core network; for example, the function management unit 1 may include a function of querying adjacent access network equipment, a function of querying adjacent terminals, a data storage function, a data privacy protection function, a computing offloading function, a data forwarding function, an access function, etc. The function management unit 2 may store multiple network functions of the access network equipment; for example, the function management unit 2 may include a perception function of the access network equipment, a positioning function of the access network equipment, etc. Function management unit 3 and function

[0198] Management unit 4 may correspond to the first function management unit described above and is configured to store application functions associated with data processing in the core network and terminal devices. Exemplarily, function management unit 3 may store multiple application functions of the core network; for example, function management unit 3 may include a perception imaging function, an image question-and-answer function, a face recognition function, a target detection function, an environment modeling function, and a path planning function. Function management unit 4 may also store multiple application functions of the terminal device; for example, function management unit 4 may include a voice recognition function and a text-to-image function.

[0199] The data processing unit 101 can obtain multiple application functions and multiple network functions in each function management unit (which may include function management unit 1, function management unit 2, function management unit 3, and function management unit 4 in Figure 3), and select at least one first function and at least one second function for the target network configuration from the multiple application functions and multiple network functions according to business demand information to generate first configuration information.

[0200] Since function management unit 1 and function management unit 2 respectively store the connection-related network functions of the core network and access network devices, the network functions of the core network and access network devices can be customized on demand according to business requirements; function management unit 3 and function management unit 4 respectively store the application functions associated with the data processing of the core network and terminal devices, and the application functions of the core network and terminal devices can be customized on demand according to business requirements.

[0201] After receiving the first configuration information from the data processing unit 101, the network control unit 102 creates or configures function instances corresponding to the respective functions according to the at least one first function and the at least one second function indicated by the first configuration information. Exemplarily, the at least one first function indicated by the first configuration information includes an application function of the core network and an application function of the terminal device, and the at least one second function indicated includes a network function of the core network and a network function of the access network device. Then, the network control unit 102 creates a first function instance corresponding to the first function in the core network according to the at least one first function, configures the first function instance corresponding to the first function for the terminal device, and creates a second function instance corresponding to the second function in the core network according to the at least one second function, and configures the second function instance corresponding to the second function for the access network device.

[0202] After the network control unit 102 creates or configures each function instance (including the first function instance and the second function instance in the previous paragraph), it establishes a connection between the function instances (including the first function instance and the second function instance) based on the inter-function connection relationship indicated by the first configuration information, thereby achieving on-demand customization of terminal device functions, access network device functions, and core network functions. The network control unit 102 can also establish a connection between the function instance (including the first function instance and the second function instance) and at least one of the terminal device 111, the access network device 112, and the first core network device 113. In addition, in the system architecture shown in Figure 3, the network control unit 102 can also perform functional configuration on the access network device 112 and / or the terminal device 111; illustratively, if the network control unit 102 determines that the first function is the function of the access network device 112, the network control unit 102 can perform corresponding functional configuration for the access network device 112 to implement the operation of the first function instance corresponding to the first function on the access network device 112; if the network control unit 102 determines that the first function is the function of the terminal device 111, the network control unit 102 can perform corresponding functional configuration for the terminal device 111 to implement the operation of the first function instance corresponding to the first function on the terminal device 111.

[0203] It should be noted that, based on the system architecture shown in Figure 3, when the communication system 10 creates a target network, it can customize the first and second functions of the core network, customize the second function of the access network device, and customize the first function of the terminal device according to the business demand information; and the functions of the terminal device 111 and the access network device 112 can be configured accordingly according to the first function of the core network. Since the first function is an application-related function, it is possible to run third-party applications on the terminal device 111 and / or the access network device 112.

[0204] The terminal device of the embodiment of the present application may also be referred to as a terminal, a terminal device, a user equipment (UE), a mobile station, or a mobile terminal. The terminal device can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, or smart city. For example, the terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, or a smart home device.

Optionally, the RAN may be a 3GPP-related cellular system, for example, a 4G mobile communication system (such as an LTE system), a 5G mobile communication system (such as an NR system), or a future-oriented evolution system (such as a 6G mobile communication system).

Optionally, the access network device may also be a server, a wearable device, a vehicle or an onboard device. For example, the access network device in vehicle to everything (V2X) technology may be a road side unit (RSU).

[0208] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0209] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called an open centralized unit (O-CU) or an open CU, DU may also be called an open distributed unit (O-DU), CU-CP may also be called an open centralized unit control plane (O-CU-CP), CU-UP may also be called an open centralized unit user plane (O-CU-UP), and RU may also be called an open radio unit (O-RU).

They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; or in the air on aircraft, balloons, and satellites.

[0212] In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more.

[0217] The technical solutions of the embodiments of the present application are described in detail below.

[0218] The following first introduces the process of creating the target network.

[0219] 1. Create the target network.

[0220] Optionally, the embodiment of the present application may create a target network through a communication system as shown in FIG1 .

[0221] The following is a detailed description of the process of creating a target network according to an embodiment of the present application in conjunction with FIG4. As shown in FIG4, the method of creating a target network according to an embodiment of the present application may include the following steps:

[0222] Step 400: The data processing unit obtains business demand information.

[0223] For example, the services of the embodiments of the present application may be services that integrate AI and communications, such as services for monitoring vehicle or pedestrian traffic, detecting intrusions, planning tasks, and planning routes.

[0224] The business demand information acquired by the data processing unit of the embodiment of the present application can be the user demand proposed by the user for the business; when the user needs to create a target network for a certain business, the user can propose business demand information related to the business. For example, for the business of monitoring vehicle or pedestrian flow, the business demand information can be monitoring the pedestrian and vehicle flow at intersection A during a first time period; or for the business of detecting intrusions, the business demand information can be detecting whether there is an intruder in room B during a second time period; for the business of planning tasks, the business demand information can be an execution plan for planning tasks for multiple collaborative robots (such as an execution plan for planning transportation work); for the business of planning paths, the business demand information can be planning a flight path for a drone, etc.

[0225] The data processing unit may obtain business demand information in the following ways:

[0226] Mode 1: The data processing unit receives the service demand information sent by the terminal device.

[0227] In mode 1, a user may input service requirement information for a service on a terminal device, and the terminal device sends the service requirement information input by the user to a data processing unit.

[0228] Method 2: The data processing unit obtains the business requirement information input by the user.

[0229] Illustratively, the data processing unit may be configured with a communication interface, through which a user may input business requirement information.

[0230] Optionally, the data processing unit of the embodiment of the present application can be implemented by a network model; illustratively, the data processing unit can be an AI model. The network model can receive business demand information sent by the terminal device, or obtain business demand information input by the user.

[0231] Step 401: The data processing unit sends first configuration information to the network control unit. Correspondingly, the network control unit receives the first configuration information from the data processing unit. The first configuration information is used to create a target network corresponding to the service.

[0232] In this step, the data processing unit determines first configuration information for creating a target network corresponding to the service according to the service requirement information, and sends the first configuration information to the network control unit.

[0233] The first configuration information is used to configure at least one first function and at least one second function. The first function and the second function can be referred to in the above description and will not be repeated here.

[0234] In a possible implementation manner, the data processing unit determines at least one first function and at least one second function from a plurality of functions according to the business requirement information, and generates first configuration information.

[0235] In the process of the data processing unit determining at least one first function and at least one second function, the data processing unit may screen out functions required for realizing the business requirement and creating the target network from multiple functions according to the business requirement information.

[0236] The multiple functions may be functions stored in a data processing unit. For example, the data processing unit may be implemented by an AI model. During the AI ​​model training process, a large amount of sample data is required to train the AI ​​model. The multiple functions may be sample data stored in the data processing unit during the training process.

[0237] In addition, the data processing unit may also obtain multiple functions from other units (modules or devices). Optionally, the data processing unit may obtain multiple functions from the function management unit, and the data processing unit determines at least one first function and at least one second function from the multiple functions based on the business requirement information, and generates the first configuration information.

[0238] The function management unit of the embodiment of the present application can store multiple functions, wherein the multiple functions stored in the function management unit can include network functions related to connection and application functions related to data processing. For example, as described above, the function management unit can further include a first function management unit and a second function management unit, the first function management unit is used to manage application functions, and the second function management unit is used to manage network functions,

[0239] Exemplarily, the network functions stored in the function management unit may include a function of querying neighboring base stations, a function of querying neighboring terminals, a data storage function, a data privacy protection function, a computing offloading function, a data forwarding function, an access function, etc.; the application functions stored in the function management unit may include a perception imaging function, an image question and answer function, a face recognition function, a target detection function, an environment modeling function, a path planning function, etc.

[0240] Optionally, the function management unit may send the stored multiple functions to the data processing unit; illustratively, the function management unit sends multiple application functions to the data processing unit, and the function management unit sends multiple network functions to the data processing unit.

[0241] Accordingly, after receiving multiple functions, the data processing unit allocates identification information to each function; illustratively, the identification information allocated by the data processing unit to each function may be a function sequence number (or serial number).

[0242] Optionally, after receiving each function from the function management unit, the data processing unit returns a confirmation message to the function management unit. The confirmation message may include identification information corresponding to the function.

[0243] In addition, when the function stored in the function management unit changes, such as updating the function, deleting the function, etc., the function management unit sends the changed function to the data processing unit (for example, the function management unit sends the attribute information and / or identification information of the changed function to the data processing unit).

[0244] After obtaining the business requirement information, the data processing unit determines at least one first function and at least one second function required to create a target network corresponding to the business requirement information from multiple functions, thereby generating first configuration information for configuring the at least one first function and the at least one second function.

[0245] For example, the business requirement information is to detect whether room A is invaded within a second time period. The data processing unit can determine, based on the business requirement information, at least one first function including: the face recognition function of the core network, and can determine at least one second function including: the perception function of the terminal device and the data forwarding function of the core network.

[0246] After determining at least one first function and at least one second function from the plurality of functions, the data processing unit generates first configuration information; wherein the first configuration information may include:

[0247] Indication information of each first function in at least one first function, indication information of each second function in at least one second function, and a connection relationship between any two functions in at least one first function and at least one second function.

[0248] The indication information of the first function is used to indicate the first function, for example, the indication information of the first function may be identification information of the first function, or the indication information of the first function may be the function name of the first function. The indication information of the second function is used to indicate the second function, for example, the indication information of the second function may be identification information of the second function, or the indication information of the second function may be the function name of the second function.

[0249] The connection relationship between any two of the at least one first function and the at least one second function can represent the connection relationship between the functions. For example, the at least one first function includes function 1 (the core network's face recognition function), and the at least one second function includes function 2 (the terminal device's perception function) and function 3 (the core network's data forwarding function). Because the core network's face recognition function relies on the terminal device's perception function, the output data of the terminal device's perception function must be forwarded to the core network's face recognition function via the core network's data forwarding function. Therefore, the connection relationship includes the connection relationship between function 2 and function 3, and the connection relationship between function 3 and function 1.

[0250] Optionally, the first configuration information may include resource occupancy information and / or configuration parameters of each first function in at least one first function, and the first configuration information may also include resource occupancy information and / or configuration parameters of each second function in at least one second function.

[0251] Exemplarily, the resource occupancy information may be used to characterize the size of resources occupied by a function, and the configuration parameters may include specific parameters for configuring the corresponding function (eg, the configuration parameters may include values ​​of various parameters).

[0252] Step 402: The network control unit creates a target network according to the first configuration information, wherein the target network includes at least one first function and at least one second function.

[0253] Optionally, after receiving the first configuration information, the network control unit may determine whether it is necessary to create a target network. Exemplarily, after receiving the first configuration information, the network control unit determines whether it is necessary to create a target network based on the indication information of at least one first function and the indication information of at least one second function included in the first configuration information; for example, if a network including the at least one first function and the at least one second function already exists, then it is not necessary to recreate the target network; if a network including the at least one first function and the at least one second function does not exist, then it is necessary to create the target network.

[0254] The network control unit creates a target network, which may include creating multiple function instances included in the target network, establishing connections between the multiple function instances, establishing connections between the multiple function instances and communication equipment, and performing functional configuration on the communication equipment; wherein the communication equipment includes at least one of a first core network device, an access network device, and a terminal device.

[0255] The following example describes the process of the network control unit creating a target network.

[0256] Step 1: The network control unit creates multiple function instances including the target network.

[0257] The multiple function instances include a first function instance corresponding to the first function and a second function instance corresponding to the second function.

[0258] In this step, the network control unit can determine the communication device corresponding to each function (including the first function and the second function) included in the first configuration information (exemplarily, the communication device can be one of the first core network device, the access network device and the terminal device). Among them, the communication device corresponding to the function can be understood as the communication device containing a module with the function; the module can be a software module, a hardware module, or a module combining software and hardware. After determining the communication device corresponding to each function, the network control unit can create a function instance corresponding to the function on the corresponding communication device according to the indication information and resource occupancy information of each function (create a first function instance for the first function, and create a second function instance for the second function).

[0259] Alternatively, the network control unit may determine a core network function included in the first configuration information, where the core network function may be understood as a function implemented by the core network. The network control unit may create a function instance corresponding to the core network function; wherein the network control unit creating the function instance corresponding to the core network function includes: creating a first function instance corresponding to the first function of the core network and creating a second function instance corresponding to the second function of the core network.

[0260] In the following description of this application, a function instance corresponding to the function of the network control unit to create a core network is introduced as an example.

[0261] Optionally, the network control unit may create a corresponding function instance for the core network function in the at least one first function and the at least one second function indicated by the first configuration information.

[0262] One possible implementation is that, for a target first function among at least one first function indicated by the first configuration information (wherein the target first function is a function of the core network), the network control unit creates a first function instance corresponding to the target first function in the core network according to the indication information of the target first function and the resource occupancy information of the target first function. Furthermore, for a target second function among at least one second function indicated by the first configuration information (wherein the target second function is a function of the core network), the network control unit creates a second function instance corresponding to the target second function in the core network according to the indication information of the target second function and the resource occupancy information of the target second function.

[0263] It should be noted that at least one first function may include one or more target first functions. When at least one first function includes multiple target first functions, the network control unit creates a first function instance for each target first function. At least one second function may include one or more target second functions. When at least one second function includes multiple target second functions, the network control unit creates a second function instance for each target second function.

[0264] For a target first function in at least one first function:

[0265] The network control unit determines the attribute information corresponding to the target first function according to the indication information of the target first function; and creates a first function instance corresponding to the target first function in the core network according to the attribute information and resource occupancy information corresponding to the target first function.

[0266] Optionally, when determining the attribute information corresponding to the target first function, the network control unit may determine the attribute information corresponding to the target first function in the following multiple ways:

[0267] Attribute information determination method 1: the network control unit obtains the stored attribute information corresponding to the target first function.

[0268] When determining the attribute information corresponding to the target first function, the network control unit searches for the attribute information corresponding to the target first function from the attribute information of multiple functions stored in the network control unit according to the indication information of the target first function.

[0269] Exemplarily, the network control unit may receive and save the attribute information of the target first function sent by the data processing unit. For example, the first configuration information sent by the data processing unit to the network control unit includes the attribute information of each first function. After receiving the first configuration information, the network control unit saves the attribute information of each first function.

[0270] Attribute information determination method 2: the network control unit obtains attribute information corresponding to the target first function from the function management unit.

[0271] When determining the attribute information corresponding to the target first function, the network control unit obtains the attribute information corresponding to the target first function from the function management unit according to the indication information of the target first function.

[0272] Exemplarily, the network control unit sends a query request to the function management unit, which includes indication information of the target first function; the function management unit stores attribute information of multiple functions. After receiving the query request, the function management unit searches for attribute information corresponding to the indication information of the target first function and sends the attribute information corresponding to the target first function to the network control unit.

[0273] The attribute information of the first function includes at least one of the following information:

[0274] Function name, function description information, function input information, function output information, configurable parameter types, and function deployment conditions.

[0275] For a target second function in at least one second function:

[0276] The network control unit determines the attribute information corresponding to the target second function according to the indication information of the target second function; and creates a second function instance corresponding to the target second function in the core network according to the attribute information and resource occupancy information corresponding to the target second function.

[0277] Optionally, when determining the attribute information corresponding to the target second function, the network control unit may determine the attribute information corresponding to the target second function in the following multiple ways:

[0278] Attribute information determination method 1: the network control unit obtains the stored attribute information corresponding to the target second function.

[0279] When determining the attribute information corresponding to the target second function, the network control unit searches for the attribute information corresponding to the target second function from the attribute information of multiple functions stored in the network control unit according to the indication information of the target second function.

[0280] Exemplarily, the network control unit may receive and save the attribute information of the target second function sent by the data processing unit. For example, the first configuration information sent by the data processing unit to the network control unit includes the attribute information of each second function. After receiving the first configuration information, the network control unit saves the attribute information of each second function.

[0281] Attribute information determination method 2: the network control unit obtains attribute information corresponding to the target second function from the function management unit.

[0282] When determining the attribute information corresponding to the target second function, the network control unit obtains the attribute information corresponding to the target second function from the function management unit according to the indication information of the target second function.

[0283] Exemplarily, the network control unit sends a query request to the function management unit, which includes indication information of the target second function; the function management unit stores attribute information of multiple functions. After receiving the query request, the function management unit searches for attribute information corresponding to the indication information of the target first function, and sends the attribute information corresponding to the target second function to the network control unit.

[0284] The attribute information of the second function includes at least one of the following information:

[0285] Function name, function description information, function input information, function output information, configurable parameter types, and creation method instructions.

[0286] Step 2: The network control unit establishes connections between multiple function instances.

[0287] The network control unit establishes a connection between the first function instance and the second function instance according to the connection relationship included in the first configuration information.

[0288] Based on the above step 1, the network control unit creates, for the first function and the second function of the core network, a first function instance corresponding to each first function of the core network, and a second function instance corresponding to each second function of the core network in the core network. Based on step 1, the network control unit creates at least one first function instance and at least one second function instance in the core network; the network control unit may establish a connection between any two function instances of the at least one first function instance and the at least one second function instance based on the connection relationship included in the first configuration information.

[0289] Exemplarily, the first configuration information includes the perception function (second function) of the terminal device, the data forwarding function (second function) of the core network, the face recognition function (first function) of the core network, the connection relationship between the perception function of the terminal device and the data forwarding function of the core network, and the connection relationship between the data forwarding function of the core network and the face recognition function of the core network. After the core network creates a data forwarding function instance corresponding to the data forwarding function and a face recognition function instance corresponding to the face recognition function, a connection is established between the data forwarding function instance and the face recognition function instance.

[0290] Step 3: The network control unit establishes a connection between the multiple function instances and at least one of the first core network device, the access network device, and the terminal device included in the target network.

[0291] The multiple function instances include a first function instance and a second function instance created in the core network.

[0292] Optionally, for the first function instance and the second function instance created in step 1, a connection is established between the first function instance and the access network device and / or the terminal device, and a connection is established between the second function instance and the access network device and / or the terminal device.

[0293] One possible implementation method is that the network control unit establishes a connection between the first function instance and the access network device and / or terminal device according to the connection relationship included in the first configuration information, and establishes a connection between the second function instance and the access network device and / or terminal device.

[0294] The network control unit determines a communication device corresponding to each first function included in the first configuration information (illustratively, the communication device may be one of a first core network device, an access network device, and a terminal device). The communication device corresponding to the first function may be understood as a communication device including a module having the first function; the module may be a software module, a hardware module, or a combination of software and hardware.

[0295] Exemplarily, the network control unit may determine the communication device corresponding to the first function based on the indication information of the first function, or the network control unit may determine the communication device corresponding to the first function based on the attribute information of the first function (such as the function name).

[0296] For any first function instance created in step 1, if it is determined, based on the connection relationship included in the first configuration information, that the first function corresponding to the first function instance is associated with the function of the terminal device (for example, the function of the terminal device in at least one first function and at least one second function indicated by the first configuration information), then a connection is established between the first function instance and the terminal device. Exemplarily, if the first configuration information includes a connection between a perception function of the terminal device and a face recognition function of the core network, the network control unit establishes a connection between the face recognition function instance and the terminal device after creating a face recognition function instance corresponding to the face recognition function in the core network.

[0297] The network control unit determines a communication device corresponding to each second function included in the first configuration information (illustratively, the communication device may be one of the first core network device, the access network device, and the terminal device). The communication device corresponding to the second function may be understood as including a module having the second function; the module may be a software module, a hardware module, or a combination of software and hardware.

[0298] Exemplarily, the network control unit may determine the communication device corresponding to the second function based on the indication information of the second function, or the network control unit may determine the communication device corresponding to the second function based on the attribute information of the second function (such as the function name).

[0299] For any second function instance created in step 1, if it is determined, based on the connection relationship included in the first configuration information, that the second function corresponding to the second function instance is associated with a function of the access network device (for example, a function of the access network device in at least one first function and at least one second function indicated by the first configuration information), then a connection is established between the second function instance and the access network device. Exemplarily, if the first configuration information includes a connection between a perception function of the access network device and a data forwarding function of the core network, then after the network control unit creates a data forwarding function instance corresponding to the data forwarding function in the core network, it establishes a connection between the data forwarding function instance and the access network device.

[0300] It should be noted that the embodiment of the present application does not limit the order in which the above steps 2 and 3 are executed.

[0301] Step 4: The network control unit performs functional configuration on at least one of the first core network device, the access network device and the terminal device according to the first configuration information.

[0302] The network control unit configures the first function for at least one of the first core network device, the access network device and the terminal device according to the configuration parameters of the first function.

[0303] Exemplarily, the network control unit determines a communication device corresponding to each first function included in the first configuration information (exemplarily, the communication device may be one of a first core network device, an access network device, and a terminal device); the network control unit configures the first function for the first function and the corresponding communication device. For example, if the first function is a target detection function of the terminal device, the network control unit configures the terminal device according to the configuration parameters of the target detection function, so that the terminal device has the target detection function.

[0304] The network control unit may determine the communication device corresponding to the first function based on the indication information of the first function, or the network control unit may determine the communication device corresponding to the first function based on the attribute information of the first function (such as the function name).

[0305] The network control unit configures the second function for at least one of the first core network device, the access network device and the terminal device according to the configuration parameters of the second function.

[0306] Exemplarily, the network control unit determines a communication device corresponding to each second function included in the first configuration information (exemplarily, the communication device may be one of the first core network device, the access network device, and the terminal device); the network control unit configures the second function for the corresponding communication device. For example, if the second function is a perception function of the access network device, the network control unit configures the access network device according to the configuration parameters of the perception function, so that the access network device has the perception function.

[0307] The network control unit may determine the communication device corresponding to the second function based on the indication information of the second function, or the network control unit may determine the communication device corresponding to the second function based on the attribute information of the second function (such as the function name).

[0308] The following describes the specific ways in which the network control unit performs functional configuration for the first core network device, access network device, and terminal device respectively.

[0309] 1. Terminal equipment:

[0310] The network control unit sends first configuration indication information to the terminal device, where the first configuration indication information is used to indicate the configuration of the first function and / or the second function.

[0311] Correspondingly, the terminal device receives the first configuration indication information from the network control unit and performs function configuration according to the first configuration indication information.

[0312] Optionally, the first configuration indication information includes configuration parameters of the first function and / or configuration parameters of the second function.

[0313] Exemplarily, when the first function is a function of a terminal device (in this application, the function of a terminal device can be understood as a function performed by the terminal device), the network control unit sends first configuration indication information to the terminal device, where the first configuration indication information is used to instruct the configuration of the first function, and the first configuration indication information includes configuration parameters of the first function. The terminal device configures the first function according to the configuration parameters of the first function.

[0314] As another example, when the second function is a function of the terminal device, the network control unit sends first configuration indication information to the terminal device, where the first configuration indication information is used to instruct configuration of the second function, and the first configuration indication information includes configuration parameters of the second function. The terminal device configures the second function based on the configuration parameters of the second function.

[0315] 2. Access network equipment:

[0316] The network control unit sends second configuration indication information to the access network device, where the second configuration indication information is used to instruct configuration of the first function and / or the second function.

[0317] Correspondingly, the access network device receives the second configuration indication information from the network control unit, and performs function configuration according to the second configuration indication information.

[0318] Optionally, the second configuration indication information includes configuration parameters of the first function and / or configuration parameters of the second function.

[0319] Exemplarily, when the first function is a function of an access network device (in this application, the function of an access network device can be understood as a function performed by the access network device), the network control unit sends second configuration indication information to the access network device, where the second configuration indication information is used to instruct configuration of the first function, and the second configuration indication information includes configuration parameters of the first function. The access network device configures the first function based on the configuration parameters of the first function.

[0320] In another exemplary embodiment, when the second function is a function of the access network device, the network control unit sends second configuration indication information to the access network device, where the second configuration indication information is used to instruct configuration of the second function, and the second configuration indication information includes configuration parameters of the second function. The access network device configures the second function based on the configuration parameters of the second function.

[0321] 3. First core network equipment:

[0322] The network control unit sends third configuration indication information to the first core network device, where the third configuration indication information is used to indicate the configuration of the first function and / or the second function.

[0323] Correspondingly, the first core network device receives the third configuration indication information from the network control unit, and performs function configuration according to the third configuration indication information.

[0324] Optionally, the third configuration indication information includes configuration parameters of the first function and / or configuration parameters of the second function.

[0325] Exemplarily, when the first function is a function of a first core network device, the network control unit sends third configuration indication information to the first core network device, where the third configuration indication information is used to instruct configuration of the first function, and the third configuration indication information includes configuration parameters of the first function. The first core network device configures the first function based on the configuration parameters of the first function.

[0326] Also illustratively, when the second function is a function of the first core network device, the network control unit sends third configuration indication information to the first core network device, where the third configuration indication information is used to instruct configuration of the second function, and the third configuration indication information includes configuration parameters of the second function. The first core network device configures the second function based on the configuration parameters of the second function.

[0327] It should be noted that the embodiment of the present application does not limit the order in which the above step 4 and the above steps 1 to 3 are executed.

[0328] Through the above steps, the network control unit of the embodiment of the present application can create a target network corresponding to the business demand information, thereby realizing the creation of the target network according to user needs.

[0329] Optionally, after creating the target network, the network control unit determines the indication information of the target network (exemplarily, the indication information of the target network may be an identifier of the target network); the network control unit may send a first notification message of successful network creation to the data processing unit, and the first notification message may include the indication information of the target network.

[0330] In addition, the data processing unit may send a second notification message of successful network creation to the terminal device, wherein the second notification message may include indication information of the target network, for notifying the terminal device that the target network corresponding to the service requirement information is successfully created. The terminal device may be a terminal that sends service requirement information to the data processing unit.

[0331] Optionally, after creating the target network, the network control unit sends relevant information of the target network to the access network device or the network function entity in the core network (such as the access and mobility management function (AMF) or the unified data repository (UDR)); exemplarily, the relevant information of the target network may include indication information of the target network and business demand information corresponding to the target network; or, the relevant information of the target network may also include access information of the target network.

[0332] The following describes the overall process of creating a target network according to an embodiment of the present application with reference to FIG5 , which may include the following steps:

[0333] Step 500: The terminal device sends a network creation request to the data processing unit.

[0334] The network creation request may include business requirement information, or the network creation request may also include information such as network scope and SLA requirements.

[0335] Exemplarily, the network range may be a geographical area where the network is applicable; accordingly, after the network is created, user terminals within the network range may access the network and obtain service data generated by the network.

[0336] Step 501: The data processing unit generates first configuration information according to business requirement information.

[0355] In the description below, after the terminal device accesses the core network, the device in the core network that communicates with the terminal device can be called a second core network device (such as AMF), where the second core network device is different from the first core network device mentioned above, and the first core network device is the core network device included in the created target network.

[0356] In an embodiment of the present application, after a terminal device accesses the core network, if the access network device includes relevant information about the target network, the access network device sends the relevant information about the target network to the terminal device. If the second core network device includes relevant information about the target network, the second core network device sends the relevant information about the target network to the terminal device, or the second core network device may also obtain relevant information about the target network from the UDR and send the relevant information about the target network to the terminal device.

[0357] The relevant information of the target network may include indication information of the target network and service requirement information corresponding to the target network.

[0358] Optionally, the terminal device may determine to access the target network based on the indication information of the target network and the service requirement information corresponding to the target network.

[0364] In this case, after creating the target network, the network control unit sends relevant information of the target network to the access network device; the relevant information of the target network includes access information of the target network.

[0365] The access network device determines the access information corresponding to the target network based on the indication information of the target network carried in the access request; the access network device forwards the access request of the terminal device to the core network access function instance of the target network based on the access information corresponding to the target network.

[0366] The core network access function instance may be a second function instance in the target network.

[0367] Correspondingly, the core network access function instance receives the access request of the terminal device and sends an access confirmation message to the access network device.

[0534] In order to better explain the technical solution of the embodiment of the present application, the solution of creating a target network in the embodiment of the present application is introduced below using several examples.

[0535] Example 1:

[0536] The business requirement information is to count the pedestrian and vehicle flows at intersection A during the first time period and monitor accidents.

[0537] The data processing unit obtains the business demand information and determines that the first function required to create the target network includes: the perception imaging function of the core network and the image question and answer function of the core network; and determines that the second function required to create the target network includes the perception function of the access network device and the data forwarding function of the core network, wherein the data forwarding function is responsible for forwarding data between the access network device and the core network function. The data processing unit generates first configuration information, which includes: the identifier of the access network device, the configuration parameters of the perception function of the access network device (such as the perception azimuth, perception target, perception time period and other parameters), the identifier of the perception imaging function, the identifier of the image question and answer function, the connection relationship between the perception function and the data forwarding function of the access network device, the connection relationship between the data forwarding function and the perception imaging function, the connection relationship between the perception imaging function and the image question and answer function, and resource usage information of each function.

[0538] The data processing unit sends first configuration information to the network control unit.

[0539] The network control unit creates a target network based on the first configuration information. For example, the target network may be as shown in FIG12 . The target network includes a perception imaging function instance, an image question and answer function instance, and a data forwarding function instance created in the core network. Connections are established between the data forwarding function instance and the access network device, as well as between the data forwarding function instance and the perception imaging function instance, and between the perception imaging function instance and the image question and answer function instance. Furthermore, the perception function is configured for the access network device based on the configuration parameters of the perception function of the access network device.

[0540] Example 2:

[0541] The business requirement information is to detect whether there is anyone intruding into room B within the second time period.

[0542] The data processing unit obtains the service requirement information and determines that the first function required for establishing the target network includes: the face recognition function of the core network; and determines that the second function required for establishing the target network includes: the terminal's perception function and the core network's data forwarding function. The data processing unit generates first configuration information, which includes: an identifier of the terminal device, an identifier of the access network device to which the terminal device is connected (the terminal device needs to access the core network through the access network device), configuration parameters of the terminal's perception function (perception direction, perception time, etc.), an identifier of the data forwarding function, an identifier of the face recognition function, a connection between the data forwarding function and the face recognition function, and a connection between the access network device to which the terminal device is connected and the data forwarding function.

[0543] The data processing unit sends first configuration information to the network control unit.

[0544] The network control unit creates a target network based on the first configuration information. For example, the target network may be as shown in FIG13 . The target network includes a data forwarding function instance and a face recognition function instance created in the core network. Since the output data of the terminal device's perception function needs to be sent to the data forwarding function instance through the access network device, a connection is established between the access network device accessed by the terminal device and the data forwarding function, and a connection is established between the data forwarding function instance and the face recognition function instance. The perception function is configured for the terminal device based on the configuration parameters of the perception function of the terminal device.
