Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a communication system, a communication method, and a device. Background Art

[0002] In the 5th generation (5G) communication system, in order to meet the different quality of service requirements put forward by different industries, users, or services for the network, the network slicing technology has emerged. A network slice is to provide multiple dedicated, virtualized, and isolated logical networks on the same shared infrastructure, and each logical network serves a specific type of service or industry user. Each network slice can flexibly define its own logical topology, service level agreement (SLA) requirements, reliability, and security level to meet the differentiated requirements of different services or users.

[0003] For example, enhanced mobile broadband (eMBB) services have high requirements for transmission rate, massive machine type communication (mMTC) services require the network to support massive device access and frequent transmission of a large number of small packets, 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.

[0004] Therefore, the 5G communication system realizes the customization of network functions for connected services based on network slicing and network function virtualization (NFV) technologies. However, in the future 6th generation (6G) communication system, with the emergence of new services (new services integrating artificial intelligence (AI) and communication), the current network function customization scheme in the 5G communication system will not be able to meet the needs of new services.

[0188] 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 in the embodiments 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 in the embodiments of the present application can be deployed on different physical devices.

The embodiments of the present application do not limit the deployment manner of the data processing unit 101, the network control unit 102, and the function management unit 103 included in the communication system 10.

[0189] 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 embodiments of the present application can all be implemented in software or hardware, and the embodiments of the present application do not limit this.

[0190] In the embodiments of the present application, the communication system 10 can create a corresponding target network according to the service requirement information. When the service requirement information is different, the communication system 10 can create different target networks. Among them, the communication system 10 can customize the functions of the core network according to the service requirement information as needed, or the communication system 10 can also customize the functions of the core network, the access network device, and the terminal device according to the service requirement information as needed. The following will be introduced separately in combination with several specific system architectures.

[0191] As Figure 2 shown in a schematic diagram of a possible system architecture applicable to the embodiments of the present application. Taking Figure 2Taking the function management unit 103 in the shown system architecture as an example, which includes a first function management unit and a second function management unit; among them, the first function management unit stores multiple application functions associated with data processing, and the second function management unit stores multiple network functions associated with connections. Exemplarily, the multiple application functions stored in the first function management unit may include: sensing imaging function, image question answering 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 station function, querying neighboring terminal function, data storage function, data privacy protection function, computing offloading function, data forwarding function, access function, etc.

[0192] 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 to generate the first configuration information. After receiving the first configuration information from the data processing unit 101, the network control unit 102 creates at least function instances in the network and establishes connections between the function instances according to the at least one first function and at least one second function indicated by the first configuration information. If the first function is a function of the core network (wherein, the function of the core network in the embodiments of the present application can be understood as the function executed by the first core network device), then a first function instance corresponding to the first function is created in the core network, and if the second function is a function of the core network, then a second function instance corresponding to the second function is created in the core network, and connections between the function instances (including the first function instance and the second function instance) are established, so as to realize the on-demand customization of the core network function. The network control unit 102 can also establish connections between the function instances (including the first function instance and the second function instance) and the terminal device 111 and / or the access network device 112; Exemplarily, if the first function is a function of the core network and there is a dependency relationship between the function of the first function and the function of the access network device 112, then after creating the first function instance corresponding to the first function in the core network, a connection between the first function instance and the access network device 112 can be established. In addition, in such as Figure 2In the system architecture shown, the network control unit 102 can 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 the function corresponding to the access network device 112, the network control unit 102 can perform corresponding function configuration for 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 the function corresponding to the terminal device 111, the network control unit 102 can perform corresponding function configuration for the terminal device 111 and configure the first function for the terminal device 111.

[0193] It should be noted that based on the system architecture as Figure 2 shown above, when creating a target network, the communication system 10 can customize the first function and the second function of the core network 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, Figure 2 the multiple application functions stored in the function management unit 1 and the multiple network functions stored in the function management unit 2 can be understood as the functions of the core network.

[0194] Such as Figure 3 a schematic diagram of a possible system architecture applicable to the embodiment of the present application as shown. Figure 3 In the system architecture shown, the function management unit 103 can include multiple units. For example, Figure 3 taking the function management unit 103 including four units as an example, they are the function management unit 1, the function management unit 2, the function management unit 3, and the function management unit 4 respectively. Among them, the function management unit 1 and the function management unit 2 can correspond to the above-mentioned second function management unit and are respectively used to store the network functions associated with the connection of the core network and the access network device. For example, the function management unit 1 can store multiple network functions of the core network; for example, the function management unit 1 can include functions such as querying the functions of neighboring access network devices, querying the functions of neighboring terminals, data storage function, data privacy protection function, computing offloading function, data forwarding function, access function, etc. The function management unit 2 can store multiple network functions of the access network device; for example, the function management unit 2 can include functions such as the sensing function of the access network device and the positioning function of the access network device. The function management unit 3 and the function

[0195] The management unit 4 can correspond to the above-mentioned first function management unit, and is respectively used to store the application functions related to the data processing of the core network and the terminal device. Exemplarily, multiple application functions of the core network can be stored in the function management unit 3; for example, the function management unit 3 can include functions such as perception imaging function, image question answering function, face recognition function, target detection function, environment modeling function, path planning function, etc. Multiple application functions of the terminal device can be stored in the function management unit 4; for example, the function management unit 4 can include functions such as speech recognition function, text-to-picture function, etc.

[0196] The data processing unit 101 can obtain multiple application functions and multiple network functions in each function management unit (which can include Figure 3 the function management unit 1, function management unit 2, function management unit 3, and function management unit 4 in it), 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 according to the service requirement information, and generate the first configuration information.

[0197] Since the function management unit 1 and the function management unit 2 respectively store the network functions related to the connection of the core network and the access network device, the network functions of the core network and the access network device can be customized on demand according to the service requirements; the function management unit 3 and the function management unit 4 respectively store the application functions related to the data processing of the core network and the terminal device, and the application functions of the core network and the terminal device can be customized on demand according to the service requirements.

[0198] After receiving the first configuration information from the data processing unit 101, the network control unit 102 creates or configures function instances corresponding to each function according to at least one first function and at least one second function indicated by the first configuration information. Exemplarily, if at least one first function indicated by the first configuration information includes the application functions of the core network and the terminal device, and at least one second function indicated includes the network functions of the core network and 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 at least one first function, configures a 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 at least one second function, and configures a second function instance corresponding to the second function for the access network device.

[0199] 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), and establishes the connections between the function instances (including the first function instance and the second function instance) according to the function - to - function connection relationship indicated by the first configuration information, so as to achieve the on - demand customization of the functions of the terminal device, the access network device, and the core network. The network control unit 102 can also establish the connections between the function instances (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 core network device 113. Additionally, in the system architecture as Figure 3 shown, the network control unit 102 can also perform function configuration on the access network device 112 and / or the terminal device 111; by way of example, if the network control unit 102 determines that the first function is a function of the access network device 112, the network control unit 102 can perform corresponding function configuration for the access network device 112 to implement running 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 a function of the terminal device 111, the network control unit 102 can perform corresponding function configuration for the terminal device 111 to implement running the first function instance corresponding to the first function on the terminal device 111.

[0200] It should be noted that, based on the system architecture as Figure 3 shown, when the communication system 10 creates a target network, it can customize the first function and the second function of the core network, the second function of the access network device, and the first function of the terminal device according to the service requirement information; and the functions of the terminal device 111 and the access network device 112 can be correspondingly configured according to the first function of the core network. Since the first function is an application - related function, third - party applications can be run on the terminal device 111 and / or the access network device 112.

For example, the RAN node can be a central unit (CU), distributed unit (DU), CU-control plane (CP), CU-user plane (UP), or radio unit (RU), etc. The CU and DU can be set separately, or can also be included in the same network element, such as the baseband unit (BBU).

[0214] The technical solutions of the embodiments of the present application will be introduced in detail below.

[0215] First, the creation process of the target network will be introduced below.

[0216] 1. Create the target network.

[0217] Optionally, the embodiments of the present application can be implemented through, for exampleFigure 1 The communication system shown creates a target network.

[0218] Next, in conjunction with the attached Figure 4 , the process of creating a target network in the embodiments of this application will be introduced in detail. As Figure 4 shown, the method for creating a target network in the embodiments of this application may include the following steps:

[0219] Step 400: The data processing unit obtains service requirement information.

[0220] Exemplarily, the service in the embodiments of this application may be a service that combines AI and communication. For example, services such as monitoring vehicle or pedestrian flow, detecting intrusion, planning tasks, and planning paths.

[0221] The service requirement information obtained by the data processing unit in the embodiments of this application may be the user requirements put forward by the user for the service; when the user needs to create a target network for a certain service, the user can put forward service requirement information related to the service. Exemplarily, for the service of monitoring vehicle or pedestrian flow, the service requirement information may be to monitor the pedestrian and vehicle flow at intersection A during the first time period; or for the service of detecting intrusion, the service requirement information may be to detect whether there is an intrusion in room B during the second time period; for the service of planning tasks, the service requirement information may be to plan the execution plan for tasks for multiple collaborative robots (such as planning the execution plan for handling work); for the service of planning paths, the service requirement information may be to plan the flight path for a drone, etc.

[0222] The ways for the data processing unit to obtain service requirement information may include:

[0223] Way 1: The data processing unit receives the service requirement information sent by the terminal device.

[0224] In Way 1, the user can input service requirement information for the service on the terminal device, and the terminal device sends the service requirement information input by the user to the data processing unit.

[0225] Way 2: The data processing unit obtains the service requirement information input by the user.

[0226] Exemplarily, the data processing unit may be configured with a communication interface through which the user can input service requirement information.

[0227] Optionally, the data processing unit in the embodiments of this application may be implemented through a network model; exemplarily, the data processing unit may be an AI model. This network model can receive the service requirement information sent by the terminal device or obtain the service requirement information input by the user.

[0228] Step 401: The data processing unit sends the 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.

[0229] In this step, the data processing unit determines the first configuration information for creating the target network corresponding to the service according to the service requirement information, and sends the first configuration information to the network control unit.

[0230] 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 refer to the introduction above and will not be repeated here.

[0231] In a possible implementation, the data processing unit determines at least one first function and at least one second function from multiple functions according to the service requirement information, and generates the first configuration information.

[0232] In the process of the data processing unit determining at least one first function and at least one second function, the data processing unit can screen out the functions that the target network created to meet the service requirement needs to have from multiple functions according to the service requirement information.

[0233] The multiple functions can be the functions stored in the data processing unit. Exemplarily, the data processing unit can be implemented by an AI model. During the training process of the AI model, a large amount of sample data is required to train the AI model. Then the multiple functions can be the sample data stored in the data processing unit during the training process.

[0234] In addition, the data processing unit can also obtain multiple functions from other units (modules or devices). Optionally, the data processing unit can obtain multiple functions from the function management unit. The data processing unit determines at least one first function and at least one second function from multiple functions according to the service requirement information, and generates the first configuration information.

[0235] In the function management unit of the embodiment of the present application, multiple functions can be stored. The multiple functions stored in the function management unit can include network functions related to connection and application functions related to data processing. Exemplarily, as introduced 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.

[0236] Exemplarily, the network functions stored in the function management unit may include functions such as querying neighboring base stations, querying neighboring terminals, data storage, data privacy protection, computing offloading, data forwarding, access, etc.; the application functions stored in the function management unit may include functions such as sensing imaging, image Q&A, face recognition, target detection, environment modeling, path planning, etc.

[0237] Optionally, the function management unit may send multiple stored functions to the data processing unit; exemplarily, 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.

[0238] Correspondingly, after receiving multiple functions, the data processing unit assigns identification information to each function; the identification information assigned by the data processing unit to each function may exemplarily be a function serial number (or number).

[0239] Optionally, after receiving each function from the function management unit, the data processing unit returns an acknowledgment message to the function management unit, and the acknowledgment message may include the identification information corresponding to the function.

[0240] In addition, when the functions stored in the function management unit change, such as updating functions, deleting functions, etc., the function management unit sends the changed functions to the data processing unit (exemplarily, the function management unit sends the attribute information and / or identification information of the changed functions to the data processing unit).

[0241] After obtaining the service requirement information, the data processing unit determines at least one first function and at least one second function required to create the target network corresponding to the service 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.

[0242] Exemplarily, the service requirement information is to detect whether there is an intrusion in Room A during the second time period. Based on this service requirement information, the data processing unit may determine that at least one first function includes: the face recognition function of the core network, and may determine that at least one second function includes: the sensing function of the terminal device and the data forwarding function of the core network.

[0243] After the data processing unit determines at least one first function and at least one second function from multiple functions, it generates first configuration information; the first configuration information may include:

[0244] The indication information of each first function in at least one first function, the indication information of each second function in at least one second function, and the connection relationship between any two functions in at least one first function and at least one second function.

[0245] Among them, the indication information of the first function is used to indicate the first function. For example, the indication information of the first function can be the identification information of the first function, or the indication information of the first function can 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 can be the identification information of the second function, or the indication information of the second function can be the function name of the second function.

[0246] The connection relationship between any two functions among at least one first function and at least one second function can represent the connection relationship between functions. For example, at least one first function includes Function 1 (facial recognition function of the core network), and at least one second function includes Function 2 (sensing function of the terminal device) and Function 3 (data forwarding function of the core network); since the facial recognition function of the core network depends on the sensing function of the terminal device, and the output data of the sensing function of the terminal device needs to be forwarded to the facial recognition function of the core network through the data forwarding function of the core network, the connection relationship includes the connection relationship between Function 2 and Function 3, and the connection relationship between Function 3 and Function 1.

[0247] Optionally, the first configuration information may include the resource occupancy information and / or configuration parameters of each first function among at least one first function, and the first configuration information may further include the resource occupancy information and / or configuration parameters of each second function among at least one second function.

[0248] Exemplarily, the resource occupancy information can be used to represent the size of the resources occupied by the function, and the configuration parameters may include the specific parameters for configuring the corresponding function (for example, the configuration parameters may include the values of each parameter).

[0249] Step 402: The network control unit creates a target network according to the first configuration information. Among them, the target network includes at least one first function and at least one second function.

[0250] Optionally, after receiving the first configuration information, the network control unit may determine whether a target network needs to be created. Exemplarily, after receiving the first configuration information, the network control unit determines whether a target network needs to be created according to 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 there already exists a network including the at least one first function and the at least one second function, there is no need to recreate the target network; if there does not exist a network including the at least one first function and the at least one second function, a target network needs to be created.

[0251] The creation of a target network by the network control unit 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 devices, and performing function configuration on the communication devices; wherein, the communication devices include at least one of a first core network device, an access network device, and a terminal device.

[0252] The following is an example to introduce the process of the network control unit creating a target network.

[0253] Step 1: The network control unit creates multiple function instances included in the target network.

[0254] Among them, the multiple function instances include a first function instance corresponding to a first function and a second function instance corresponding to a second function.

[0255] In this step, the network control unit can determine the communication devices 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 a first core network device, an access network device, and a terminal device). The communication device corresponding to a function can be understood as that the communication device contains a module with that function; the module can be a software module, or a hardware module, or a module combining software and hardware. After determining the communication devices corresponding to each function, the network control unit can create function instances corresponding to the functions on the corresponding communication devices 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).

[0256] Alternatively, the network control unit can determine the functions of the core network included in the first configuration information. The functions of the core network can be understood as the functions implemented by the core network. The network control unit creates function instances corresponding to the functions of the core network; wherein, the network control unit creating function instances corresponding to the functions of the core network includes: creating a first function instance corresponding to a first function of the core network and creating a second function instance corresponding to a second function of the core network.

[0257] In the following description of this application, an example is given of the network control unit creating function instances corresponding to the functions of the core network.

[0258] Optionally, the network control unit can create corresponding function instances for the core network functions among at least one first function and at least one second function indicated by the first configuration information.

[0259] In a possible implementation, for the target first function among at least one first function indicated by the first configuration information (where 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. And, for the target second function among at least one second function indicated by the first configuration information (where 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.

[0260] It should be noted that at least one first function may include one or more target first functions. When there are multiple target first functions included in at least one first function, the network control unit creates a first function instance for each target first function respectively. At least one second function may include one or more target second functions. When there are multiple target second functions included in at least one second function, the network control unit creates a second function instance for each target second function respectively.

[0261] For the target first function among at least one first function:

[0262] 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 corresponding to the target first function and the resource occupancy information.

[0263] Optionally, when the network control unit determines the attribute information corresponding to the target first function, the network control unit can determine the attribute information corresponding to the target first function in the following multiple ways:

[0264] Attribute information determination method 1: The network control unit obtains the stored attribute information corresponding to the target first function.

[0265] When the network control unit determines the attribute information corresponding to the target first function, it searches for the attribute information corresponding to the target first function from the attribute information of multiple functions stored in itself according to the indication information of the target first function.

[0266] Exemplarily, the network control unit can 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.

[0267] Attribute information determination method 2: The network control unit obtains the attribute information corresponding to the target first function from the function management unit.

[0268] 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.

[0269] Exemplarily, the network control unit sends a query request to the function management unit, and the query request includes the indication information of the target first function; the function management unit stores the attribute information of multiple functions. After receiving the query request, the function management unit searches for the 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.

[0270] Among them, the attribute information of the first function includes at least one of the following information:

[0271] Function name, function description information, input information of the function, output information of the function, configurable parameter type, function deployment condition.

[0272] For the target second function among at least one second function:

[0273] 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 corresponding to the target second function and the resource occupancy information.

[0274] Optionally, when determining the attribute information corresponding to the target second function, the network control unit can determine the attribute information corresponding to the target second function in the following multiple ways:

[0275] Attribute information determination method 1: The network control unit obtains the stored attribute information corresponding to the target second function.

[0276] 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 itself according to the indication information of the target second function.

[0277] Exemplarily, the network control unit can 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.

[0278] Attribute information determination method 2: The network control unit obtains the attribute information corresponding to the target second function from the function management unit.

[0279] 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.

[0280] Exemplarily, the network control unit sends a query request to the function management unit, and the query request includes the indication information of the target second function; the attribute information of multiple functions is stored in the function management unit. After receiving the query request, the function management unit searches for the 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.

[0281] Among them, the attribute information of the second function includes at least one of the following information:

[0282] Function name, function description information, input information of the function, output information of the function, configurable parameter type, creation method indication information.

[0283] Step 2: The network control unit establishes connections between multiple function instances.

[0284] 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.

[0285] Based on the above Step 1, for the first function and the second function of the core network, the network control unit respectively creates a first function instance corresponding to the first function of each core network and a second function instance corresponding to the second function of each 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 can establish connections between any two function instances among at least one first function instance and at least one second function instance according to the connection relationship included in the first configuration information.

[0286] Exemplarily, 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 are included in the first configuration information. After creating a data forwarding function instance corresponding to the data forwarding function and a face recognition function instance corresponding to the face recognition function in the core network, a connection is established between the data forwarding function instance and the face recognition function instance.

[0287] Step 3: The network control unit establishes connections between multiple function instances and at least one of the first core network device, access network device, and terminal device included in the target network.

[0288] Among them, the multiple function instances include a first function instance and a second function instance created in the core network.

[0289] Optionally, for the first function instance and the second function instance created in step 1, establish a connection between the first function instance and the access network device and / or the terminal device, and establish a connection between the second function instance and the access network device and / or the terminal device.

[0290] A possible implementation is that the network control unit establishes a connection between the first function instance and the access network device and / or the terminal device, and establishes a connection between the second function instance and the access network device and / or the terminal device according to the connection relationship included in the first configuration information.

[0291] The network control unit determines the communication device corresponding to each first 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 first function can be understood as that the communication device includes a module with the first function; the module can be a software module, or a hardware module, or a module combining software and hardware.

[0292] Exemplarily, the network control unit can determine the communication device corresponding to the first function according to the indication information of the first function, or the network control unit can determine the communication device corresponding to the first function according to the attribute information of the first function (such as the function name).

[0293] For any one of the first function instances created in step 1, if it is determined according to 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, it can be the function of the terminal device among at least one first function and at least one second function indicated by the first configuration information), then establish a connection between the first function instance and the terminal device. Exemplarily, if the first configuration information includes a connection between the sensing function of the terminal device and the face recognition function of the core network, then after the network control unit creates a face recognition function instance corresponding to the face recognition function in the core network, establish a connection between the face recognition function instance and the terminal device.

[0294] The network control unit determines the communication device corresponding to each 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 second function can be understood as that the communication device includes a module with the second function; the module can be a software module, or a hardware module, or a module combining software and hardware.

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

[0296] For any one of the second function instances created in step 1, if it is determined according to the connection relationship included in the first configuration information that the second function corresponding to this second function instance is associated with the function of the access network device (for example, it may be the function of the access network device among at least one first function and at least one second function indicated by the first configuration information), then a connection between this second function instance and the access network device is established. Exemplarily, if the first configuration information includes a connection between the sensing function of the access network device and the data forwarding function of the core network, after the network control unit creates a data forwarding function instance corresponding to the data forwarding function in the core network, a connection between the data forwarding function instance and the access network device is established.

[0297] It should be noted that the present application embodiment does not limit the execution order of the above steps 2 and 3.

[0298] Step 4: The network control unit performs function 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.

[0299] 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.

[0300] Exemplarily, the network control unit determines the communication devices corresponding to each first 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 first function for the first function and the corresponding communication device. For example, if the first function is the target detection function of the terminal device, then 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.

[0301] Among them, the network control unit may determine the communication device corresponding to the first function according to the indication information of the first function, or the network control unit may determine the communication device corresponding to the first function according to the attribute information of the first function (such as the function name).

[0302] 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.

[0303] Exemplarily, the network control unit determines the communication device corresponding to each second 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 second function for the corresponding communication device. For example, if the second function is the sensing function of the access network device, the network control unit configures the access network device according to the configuration parameters of the sensing function, so that the access network device has the sensing function.

[0304] Among them, the network control unit may determine the communication device corresponding to the second function according to the indication information of the second function, or the network control unit may determine the communication device corresponding to the second function according to the attribute information of the second function (such as the function name).

[0305] The following specifically describes the specific manner in which the network control unit performs function configuration for the first core network device, the access network device, and the terminal device respectively.

[0306] 1. Terminal device:

[0307] 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.

[0308] 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.

[0309] Optionally, the first configuration indication information includes the configuration parameters of the first function and / or the configuration parameters of the second function.

[0310] Exemplarily, when the first function is a function of the terminal device (the function of the terminal device in this application can be understood as the function executed 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 indicate the configuration of the first function, and the first configuration indication information includes the configuration parameters of the first function. The terminal device configures the first function according to the configuration parameters of the first function.

[0311] Exemplarily again, 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 indicate the configuration of the second function, and the first configuration indication information includes the configuration parameters of the second function. The terminal device configures the second function according to the configuration parameters of the second function.

[0312] 2. Access network device:

[0313] The network control unit sends second configuration indication information to the access network device, where the second configuration indication information is used to indicate the configuration of the first function and / or the second function.

[0314] Correspondingly, the access network device receives second configuration indication information from the network control unit, and performs function configuration according to the second configuration indication information.

[0315] Optionally, the second configuration indication information includes configuration parameters of the first function and / or configuration parameters of the second function.

[0316] Exemplarily, when the first function is a function of the access network device (the function of the access network device in this application can be understood as the function executed 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 indicate configuring the first function, and the second configuration indication information includes configuration parameters of the first function. The access network device configures the first function according to the configuration parameters of the first function.

[0317] Also exemplarily, 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 indicate configuring the second function, and the second configuration indication information includes configuration parameters of the second function. The access network device configures the second function according to the configuration parameters of the second function.

[0318] 3. First core network device:

[0319] 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 configuring the first function and / or the second function.

[0320] 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.

[0321] Optionally, the third configuration indication information includes configuration parameters of the first function and / or configuration parameters of the second function.

[0322] Exemplarily, when the first 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 indicate configuring 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 according to the configuration parameters of the first function.

[0323] Also exemplarily, 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 indicate configuring 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 according to the configuration parameters of the second function.

[0324] It should be noted that the embodiments of the present application do not limit the execution sequence of the above step 4 and the above steps 1 to 3.

[0325] Through the above steps, the network control unit in the embodiments of the present application can create a target network corresponding to the service demand information, and realize the creation of the target network according to the user demand.

[0326] 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 the identifier of the target network); the network control unit may send a first notification message indicating successful network creation to the data processing unit, and the first notification message may include the indication information of the target network.

[0327] In addition, the data processing unit may send a second notification message indicating successful network creation to the terminal device, and the second notification message may include the indication information of the target network, for notifying the terminal device that the target network corresponding to the service demand information is successfully created. Wherein, the terminal device may be the terminal that sends the service demand information to the data processing unit.

[0328] Optionally, after creating the target network, the network control unit sends the 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 the indication information of the target network, the service demand information corresponding to the target network; or, the relevant information of the target network may further include the access information of the target network.

[0330] Step 500: The terminal device sends a network creation request to the data processing unit.

[0331] The network creation request may include service demand information, or the network creation request may further include information such as network scope and SLA requirements.

[0332] Exemplarily, the network scope may be the geographical area applicable to the network; correspondingly, after the network is created, the user terminals within the network scope can access the network and obtain the service data generated by the network.

[0333] Step 501: The data processing unit generates first configuration information according to the service demand information.

[0334] The first configuration information is used to configure at least one first function and at least one second function.

[0335] Among them, for the specific manner in which the data processing unit generates the first configuration information, reference can be made to the introduction of step 401 in the foregoing text.

[0336] Step 502: The data processing unit sends the first configuration information to the network control unit.

[0337] Exemplarily, the first configuration information includes indication information of each first function among at least one first function, resource occupation information of each first function, configuration parameters of each first function, indication information of each second function among at least one second function, resource occupation information of each second function, configuration parameters of each second function, and connection relationships between any two functions among at least one first function and at least one second function.

[0338] Step 503: The network control unit acquires the attribute information of each first function and the attribute information of each second function.

[0339] Among them, for the manner in which the network control unit acquires the attribute information of each first function and the attribute information of each second function, reference can be made to the introduction of step 1 in the process of creating the target network in the foregoing text.

[0340] Step 504: The network control unit creates first function instances and second function instances in the core network and establishes connections between the function instances.

[0341] Among them, for the specific manner in which the network control unit creates first function instances and second function instances, reference can be made to the introduction of step 1 in the process of creating the target network in the foregoing text. For the specific manner in which the network control unit establishes connections between the function instances, reference can be made to the introduction of step 2 in the process of creating the target network in the foregoing text.

[0342] Step 505: The network control unit establishes connections between the first function instances and the access network devices and / or terminal devices, and establishes connections between the second function instances and the access network devices and / or terminal devices.

[0347] Among them, the first notification message may include indication information of the target network.

[0348] Step 508: The data processing unit sends a second notification message indicating successful network creation to the terminal device.

[0349] Among them, the second notification message may include indication information of the target network.

[0350] II. The terminal device accesses the target network.

[0351] In the embodiment of this application, after the terminal device accesses the core network through the access network device, the terminal device can access the created target network according to its own service requirements.

[0352] In the following description, after the terminal device accesses the core network, the device in the core network that communicates with the terminal device can be referred to as the second core network device (such as the AMF). Among them, the second core network device is different from the first core network device above, and the first core network device is the core network device included in the created target network.

[0353] In the embodiment of this application, after the terminal device accesses the core network, if the access network device includes relevant information of the target network, the access network device sends the relevant information of the target network to the terminal device. If the second core network device includes relevant information of the target network, the second core network device sends the relevant information of the target network to the terminal device, or the second core network device can also obtain the relevant information of the target network from the UDR and send the relevant information of the target network to the terminal device.

[0354] Among them, the relevant information of the target network may include indication information of the target network and service requirement information corresponding to the target network.

[0355] Optionally, the terminal device can determine to access the target network according to the indication information of the target network and the service requirement information corresponding to the target network.

[0356] Exemplarily, the terminal device may determine whether to access the target network according to the service requirements of the currently running service, the service requirement information corresponding to the target network, and the indication information of the target network; for example, when the terminal device determines that the service requirement information corresponding to the target network is consistent with the service requirements of the currently running service, the terminal device determines the target network corresponding to the indication information for accessing the target network.

[0357] After the terminal device determines to access the target network, the terminal device sends an access request to the access network device, and the access request is used to request access to the target network. Among them, the access request may include the indication information of the target network.

[0358] Correspondingly, the access network device receives the access request.

[0359] The following will be described separately for several different situations.

[0360] Situation 1:

[0361] In this situation, after creating the target network, the network control unit sends the relevant information of the target network to the access network device; the relevant information of the target network includes the access information of the target network.

[0362] The access network device determines the access information corresponding to the target network according to 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 corresponding to the target network according to the access information corresponding to the target network.

[0363] Among them, the core network access function instance may be a second function instance in the target network.

[0364] 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. Among them, the access confirmation message may carry the indication information of the target network accessed by the terminal device.

[0365] The access network device receives the access confirmation message sent by the core network access function instance and sends an access confirmation message to the terminal device, and the terminal device successfully accesses the target network.

[0366] After the terminal device accesses the target network, it may receive service data generated based on the target network.

[0367] The following combines the attached Figure 6 , to introduce the process of the terminal device accessing the target network in the embodiment of the present application. As Figure 6 shown, the method for accessing the target network in the embodiment of the present application may include the following steps:

[0368] Step 600: The terminal device sends an access request to the access network device.

[0376] Case 2:

[0377] In this case, after creating the target network, the network control unit sends the relevant information of the target network to the access network device; the relevant information of the target network does not include the access information of the target network.

[0378] The access network device fails to find the access information corresponding to the target network according to the indication information of the target network carried in the access request; then the access network device forwards the access request of the terminal device to the network control unit, and the access request includes the indication information of the target network.

[0379] Correspondingly, the network control unit receives the access request of the terminal device forwarded by the access network device; according to the indication information of the target network carried in the access request, it searches for the access information corresponding to the target network. The network control unit forwards the access request of the terminal device to the core network access function instance of the target network according to the access information corresponding to the target network.

[0380] Among them, the core network access function instance may be a second function instance in the target network.

[0381] Correspondingly, the core network access function instance receives the access request of the terminal device forwarded by the network control unit and sends an access confirmation message to the access network device. Among them, the access confirmation message may carry the indication information of the target network to which the terminal device accesses.

[0382] It should be noted that after the core network access function instance in the target network establishes a connection with the access network device, when the core network access function instance receives an access request from the terminal device, it can directly send an access confirmation message to the access network device.

[0383] The access network device receives the access confirmation message sent by the core network access function instance, sends an access confirmation message to the terminal device, and the terminal device successfully accesses the target network.

[0384] After the terminal device accesses the target network, it can receive service data generated based on the target network.

Exemplarily, the second core network device can be an AMF; in addition, if the network control unit sends the relevant information of the target network to the UDR, the AMF can obtain the relevant information of the target network from the UDR; again exemplarily, if the second core network device is other functional entities in the core network, the second core network device can obtain the relevant information of the target network from the AMF or UDR.

[0397] The access network device sends an access request of the terminal device to the second core network device, and the access request may include indication information of the target network. Exemplarily, when the second core network device is an AMF, the access network device can transparently transmit the access request of the terminal device to the AMF.

[0398] The second core network device determines the access information corresponding to the target network according to the indication information of the target network carried in the access request; the second core network device forwards the access request of the terminal device to the core network access function instance of the target network according to the access information corresponding to the target network.

[0399] Among them, the core network access function instance can be a second function instance in the target network.

[0400] 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. Among them, the access confirmation message may carry the indication information of the target network to which the terminal device accesses.

[0401] It should be noted that after the core network access function instance in the target network establishes a connection with the access network device, when the core network access function instance receives the access request of the terminal device, it can directly send an access confirmation message to the access network device.

[0402] The access network device receives the access confirmation message sent by the core network access function instance and sends an access confirmation message to the terminal device, and the terminal device successfully accesses the target network.

The network control unit forwards the access request of the terminal device to the core network access function instance of the target network according to the access information corresponding to the target network.

[0420] Among them, the core network access function instance can be a second function instance in the target network.

[0421] Correspondingly, the core network access function instance receives the access request of the terminal device forwarded by the network control unit and sends an access confirmation message to the access network device. Among them, the access confirmation message may carry the indication information of the target network to which the terminal device accesses.

[0422] It should be noted that after the core network access function instance in the target network establishes a connection with the access network device, after receiving the access request of the terminal device, the core network access function instance can directly send an access confirmation message to the access network device.
