[0252] In aspect 19, an embodiment of the present disclosure proposes a communication system, comprising a core network device, a first network node, and a second network node, wherein the core network device is configured to implement the communication method described in any one of the first aspect of the present disclosure, the first network node is configured to implement the communication method described in any one of the second aspect of the present disclosure, and the second network node is configured to implement the communication method described in any one of the third aspect of the present disclosure.

[0253] In the twentieth aspect, an embodiment of the present disclosure proposes a storage medium storing instructions. When the instructions are executed on a communication device, the communication device executes a communication method as described in any one of the first, second, third, fourth, fifth, and sixth aspects.

[0254] In aspect 21, an embodiment of the present disclosure proposes a computer program product, comprising a computer program and / or instructions, characterized in that when the computer program and / or instructions are executed by a communication device, they implement the communication method as described in any one of the first aspects, or when the computer program and / or instructions are executed by the communication device, they implement the communication method as described in any one of the second aspects, or when the computer program and / or instructions are executed by the communication device, they implement the communication method as described in any one of the third aspects, or when the computer program and / or instructions are executed by the communication device, they implement the communication method as described in any one of the fourth aspects, or when the computer program and / or instructions are executed by the communication device, they implement the communication method as described in any one of the fifth aspects, or when the computer program and / or instructions are executed by the communication device, they implement the communication method as described in any one of the sixth aspects.

[0255] Through the above method, the first network element invokes a search operation on the second network element based on the service request sent by the first network node to determine the second network node information corresponding to the service request. The first network element generates transmission rule information for the service request based on the service request. The first network element generates first information based on the transmission rule information and the second network node information. The first information is used to instruct the second network node to establish a user plane connection with the core network device based on the first information. The first network element sends the first information to the second network node via the AMF network element and receives the first connection response information fed back by the second network node via the AMF network element. Thus, a user plane connection is established through the network element architecture transmission process, filling the gap in the user plane establishment process in the service data transmission process and ensuring the transmission requirements of service data during network communication.

[0291] Figure 1B is a schematic diagram of a network communication architecture according to an embodiment of the present disclosure. As shown in Figure 1B, the network communication architecture adopts SBA (Service-based Architecture), defining network functions as various flexibly adjustable service network elements. The NSSF (Network Slice Selection Function) is used to determine the network slice instances that a UE is allowed to access based on the UE's slice selection assistance information, subscription information, and other information. The NEF (Network Exposure Function) is located between the core network and the external third-party application function body and is responsible for managing all external applications that expose network data. The NRF (Network Repository Function) is used to register and monitor the status of network function services, enabling automated management, selection, and scalability of network function services and allowing each network function to discover the services provided by other network functions. The PCF (Policy Control Function) is used to define and manage network policies to ensure user service quality and efficient use of network resources. The UDM (Unified Data Management Function) is responsible for managing user identification, subscription data, authentication data, and user service network element registration. AF (Application Function) is similar to an application server, which interacts with other core network control plane NFs and provides business services. AF can exist for different application services and can be owned by operators or trusted third parties. NSSAAF (Network Slice-Specific Authentication and Authorization Function) is used to select, authenticate and authorize network slices. AUSF (Authentication Server Function) is used to receive requests from AMF to authenticate the UE, request keys from UDM, and then forward the keys issued by UDM to AMF for authentication processing. AMF (Access and Mobility Management Function) is responsible for UE identity authentication, authorization, registration, mobility management and connection management functions. SMF (Session Management Function) is used to allocate IP addresses to UEs and is responsible for the management of various channels between UEs and the core network during communication.SCP (Service Communication Proxy) is used for communication and agency of services during the communication process. NSACF (Network Slice Admission Control Function) is used to monitor and control the number of PDU sessions established for each network slice, notify the network slice status based on events, and report to the user NF. RAN (Radio Access Network) refers to the full or partial wireless access of fixed users to the switch, which enables the UE to access the core network through RAN. UPF (User Plane Function) is used to route and forward data from the base station to the network. UPF is the module that processes data in the core network. DN (Data Network) is used to refer to the provision of data-centric network services such as the Internet, cloud / OTT services, and enterprise networks.

[0292] For example, the SBA uses a dual-bus design of a control plane and a user plane to control the transmission of control signaling and session packets between various network functions. The architecture includes the following service-based interfaces (such as N1 and N2) and reference points (such as Namf). The reference points show how various network functions interact with each other and how each NF in the control pipeline transmits data / information to other NFs via the control bus.

[0293] Figure 1C is a schematic diagram of a data storage architecture according to an embodiment of the present disclosure. As shown in Figure 1C , this data storage architecture allows the UDM, PCF, and NEF to store data in the Unified Data Repository (UDR). The UDM and PCF store subscription data and policy data, while the NEF stores structured data and application data for exposure (including packet flow descriptions for application detection, AF request information for multiple UEs, etc.).

[0294] Figure 1D is a schematic diagram illustrating a data storage architecture according to an embodiment of the present disclosure. As shown in Figure 1D , the data storage architecture consists of any NF and an Unstructured Data Storage Function (UDSF). The NF stores unstructured data in the UDSF and retrieves data from the UDSF. For example, CPNFs (Control Plane Functions) can share a UDSF to store their respective unstructured data, or each can have its own unique UDSF for storing unstructured data.

[0295] Figure 1E is a schematic diagram of a data collection architecture according to an embodiment of the present disclosure. As shown in Figure 1E , during network data analysis based on the aforementioned communication architecture, NWDAF is used for data analysis. The communication system architecture allows NWDA to collect data from other NFs via NNF channels.

[0296] In some embodiments, new network functions and architectures are designed to meet the large-scale data service requests initiated by users to the network, including services and application scenarios such as sensing, positioning, and computing. The large-scale data generated during communication is transmitted via the user plane. This embodiment designs a communication process for establishing a user plane between external nodes and the network. Deterministic transmission during the user plane transmission process is introduced into the user plane of core network devices. Data is transmitted based on deterministic transmission rules generated by CF network elements, ensuring that the network meets the communication requirements for high-quality service data transmission.

[0297] For example, Figure 1F is a schematic diagram of a network architecture shown according to an embodiment of the present disclosure. As shown in Figure 1H, a network architecture is proposed, which establishes a data and information collection function (DCF network element), an information storage function (DSF network element) and an information calculation and processing function (CF network element). The CF network element includes multiple functional modules for implementing multiple functions. For example, the task calculation function: can retrieve data collected by DCF and stored by DSF, and then provide model training and reasoning decisions throughout the entire artificial intelligence life cycle. At this time, CF acts as a scheduler, collaborating with the base station and UE to perform data splitting and model training. Task scheduling function: used to control and schedule the execution phase of artificial intelligence tasks, including control information collection and scheduling resource management. Network data collection function: used to obtain real-time network information from different NFs, and can also collect data transmitted between NFs and base stations. Network data storage function: Integrates multiple storage-related functions, such as NRF, UDR, UDSF, and ADRF. The information that can be stored includes user data (user registration data, service-related data), NF configuration files, network data (network service SLA data, network node load), and computing-related data (artificial intelligence training data, computing power resource status, location information), etc.

[0298] For example, based on the above network architecture, data is collected from other NFs and UEs through the DCF network element, and the collected data is sent to the DSF network element for storage. The CF network element schedules the data stored in the DSF network element based on the calculation request, generates the data analysis results and sends them to the DSF network element for storage. At the same time, the CF network element sends the data analysis results to the data analysis request end, thereby realizing end-to-end data collection, transmission, storage, calculation and sharing through the collaboration of UE and network, and outputting the corresponding results to external network applications conveniently and quickly. By adding functional network elements in the corresponding network architecture, the problem of intelligent data transmission related to artificial intelligence / sensing is solved.

[0299] In some embodiments, when the network receives a data service request, it analyzes the request and decides whether to use the user plane for data transmission. If there is no available user plane connection between the network node requesting the service and the network, the user plane establishment process is initiated. After the user plane is established, the network node uploads the data to the DCF network element through the user plane. The DCF network element processes the received data and sends it to the CF network element, which performs data calculations. At the same time, the DCF network element can also store the processed data in the DSF network element. For example, the CF network element can also store the data processing results in the DCF network element through the user plane, and the DCF network element transmits the data processing results to the corresponding network node.

[0300] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0301] Step S2101: The first network node sends a service request to the AMF network element.

[0302] In some embodiments, the first network node is configured to initiate a service request to a core network device. The service request may include data service requests in various large-scale data service scenarios, such as sensing service scenarios, positioning service scenarios, and AI (Artificial Intelligence) service scenarios. For example, based on the service request, the first network node requests the location information of the second network node from the core network device; based on the service request, the first network node requests AI prediction information from the core network device. Based on the service request, the core network device may need to schedule relevant data on the second network node to assist in calculating the AI ​​prediction information.

[0303] For example, in this embodiment, the core network device can judge the service request and determine whether it is necessary to build a user plane. If the service request requires scheduling multiple network elements and building a user plane for service data transmission, then the user plane is built based on the service request, and the large-scale data generated in the subsequent service request response process is transmitted according to the user plane.

[0304] In some embodiments, the first network node may be a terminal, an AF network element in a core network device, or an access network device, etc., which is a network node that initiates a service request. The first network node may also be an intermediate node for transmitting the service request, which is not limited in this embodiment.

[0305] In some embodiments, the name of the service request is not limited, and may be, for example, "request information", "service information", "user plane call information", "service demand information", etc.

[0306] In some embodiments, the service request includes at least one of the following: ID information of the first network node, service type information, service description information, service quality information, and service standard information.

[0307] For example, in this embodiment, the service request is used to describe the network service called by the first network node. The service request includes service type information corresponding to the service request, service content description information of the service request, service quality information required by the service request, and service standard information corresponding to the service request. In the process of authenticating the service request, the core network device needs to determine whether to authorize the service request. Therefore, the service request includes the ID information of the first network node. The core network device manages the service types authorized by each network node. When receiving the service request, the service request type and the ID information of the first network node in the service request are compared with the managed service type mapping relationship. If the service request type and the ID information of the first network node match the management table, the first network node is authorized to initiate the service request.

[0308] Step S2102: The AMF network element determines the first network element based on the service request and sends the service request to the first network element.

[0309] For example, in this embodiment, the AMF network element is installed in the core network equipment. The AMF network element performs access function management on the first network node based on the service request. When the first network node is authorized to access the core network based on the service request, the AMF network element determines the corresponding first network element based on the service request and sends the service request to the first network element. The first network element is a data computing function network element, which is used to calculate the large-scale data collected during the data service process to generate data calculation results. For example, the first network element is a CF network element.

[0310] For example, after the AMF network element in the core network device authorizes the first network node to access the core network device based on the service request, the AMF network element can determine the corresponding first network element according to the service request type. For example, if the service request is a location awareness request of the second network node, the AMF network element determines the first CF network element that can perform the awareness result calculation as the first network element based on the service request. The service request is sent to the first network element.

[0311] Step S2103: The first network element determines to adopt the user plane for data transmission based on the service request, and generates transmission rule information according to the service request.

[0312] For example, the service requests sent by the first network node include multiple types, such as positioning service requests, AI function service requests, sensing service requests, data transmission service requests, access service requests, session service requests, etc. The first network node determines the data transmission rule based on the service request type. If the data transmission scale corresponding to the service request is small, the first network node determines that the current service request can directly perform data transmission without the need for data transmission through the user plane. If the data transmission scale corresponding to the service request is large and requires calling more network elements, the first network node determines that the current service request requires the use of the user plane for service data transmission, and generates transmission rule information based on the service request.

[0313] In some embodiments, the transmission rule information includes at least one of the following:

[0314] Transmission delay information;

[0315] Processing delay information;

[0316] Packet size information;

[0317] Transport protocol information;

[0318] Routing protocol information;

[0319] Traffic protocol information;

[0320] Network protocol information;

[0321] Packet loss rate information;

[0322] Transmission bandwidth information.

[0323] For example, in this embodiment, when the CF network element determines that the current service request needs to use the user plane for data transmission, it generates corresponding deterministic transmission rule information according to the service request. The deterministic transmission rules include: transmission delay during data transmission, data processing delay when each node in the user plane processes data, data packet size during data interaction, transmission protocol during data transmission, routing protocol during data transmission, flow protocol during data transmission, network communication protocol, data packet loss rate and transmission bandwidth, etc. In this embodiment, deterministic transmission rules are introduced into the user plane construction process of the core network device, so that data is transmitted according to the deterministic transmission rules generated by the CF network element during data transmission, and the relevant rules in the data transmission process based on the user plane are standardized.

[0324] Step S2104: The first network element calls a search operation on the second network element according to the service request to determine the second network node information corresponding to the service request.

[0325] In an exemplary embodiment, the first network element is a data computing function network element, configured to schedule large-scale data generated by core network devices during a service request process and generate data computing results corresponding to the service request based on the large-scale data. Upon receiving the service request, the first network element first schedules and retrieves the service request, invokes a retrieval operation on a second network element, sends the service request to the second network element, and retrieves the service request based on data information stored in the second network element, thereby determining the second network node information corresponding to the service request.

[0326] In some embodiments, the second network element is a data storage function (DSF) network element, which selects and / or calculates the corresponding second network node information for the service request through the relevant data information stored in the DSF network element. For example, the service request is a location awareness service request. The first network node obtains the location information of the target network node from the core network device through the location awareness service request. The CF network element in the core network device sends the location service request to the DSF network element. When the DSF network element retrieves the target network node, the relevant information of the second network node that needs to be collected for data is obtained. The second network node can be a data collection node near the target network node that can perceive the target network node; the second network node can also be the target network node.

[0327] In some embodiments, the second network node information includes ID information of the second network node, IP address information of the second network node, device number information of the second network node, etc.

[0328] Step S2105: The first network element generates first information according to the transmission rule information and the second network node information.

[0329] In some embodiments, the first information is used to instruct the second network node to establish a user plane connection with the core network device according to the first information.

[0330] In some embodiments, the name of the first information is not limited, and it can be, for example, "user plane connection establishment request", "user plane establishment request", "establishment request information", "user plane establishment information", etc.

[0331] In some embodiments, the first information includes at least one of the following:

[0332] Service ID information;

[0333] Transmission rule information;

[0334] User plane address information of the first network element;

[0335] Internet Protocol IP address information of the first network node;

[0336] IP address information of the second network node.

[0337] In an example, a first network element generates first information based on a transmission rule and second network node information. The first information is used to establish a user plane between a core network device and another network node. The first information includes: service ID information corresponding to the service request, deterministic transmission rule information generated by the first network element, user plane address information of the first network element, and IP address information of each network node corresponding to the service request.

[0338] Step S2106: The first network element sends the first information to the third network element.

[0339] In some embodiments, the third network element is a data collection function DCF network element, the first network element is a data calculation function CF network element, and the CF network element sends first information to the DCF network element to establish a user plane connection between the CF network element and the DCF network element, so that the CF network element and the DCF network element can directly transmit data based on the user plane.

[0340] Optionally, in some embodiments, the method further includes: the first network element sending the first information to the second network element.

[0341] For example, the first network element is a CF network element, and the second network element is a DSF network element. In some service scenarios, it is necessary to establish a user plane connection between the CF network element and the DSF network element so that the CF network element can directly communicate with the DSF network element when executing a service request.

[0342] Step S2107: The third network element establishes a user plane connection with the first network element according to the first information.

[0343] For example, in this embodiment, the first network element is a CF network element, and the third network element is a DCF network element. The CF network element establishes a user plane connection with the DCF network element through the first information, so that the CF network element can schedule the DCF network element to collect data from the corresponding network node during data calculation, and feed the collected data back to the CF network element.

[0344] Step S2108, the third network element sends the first information to the SMF network element through the AMF network element.

[0345] In this example, the AMF network element is used for data transmission and forwarding, and the third network element is the DCF network element. After the user plane connection between the DCF network element and the CF network element is established through the above steps, the DCF network element sends the first information to the AMF network element, and the AMF network element sends the received first information to the SMF (Session Management Function) network element. The SMF network element is responsible for transmitting and managing user data to ensure that users can access the required services through the network.

[0346] Step S2109, the SMF network element determines the UPF network element corresponding to the first information and sends the first information to the UPF network element.

[0347] For example, one or more different types of UPF (User Plane Function) network elements can be configured in the core network device, and the UPF network element is used to implement different user functions. For example, the core network device includes: a perception function network element for perception, a function network element for performing AI model calculations, and a function network element for location determination. The SMF network element can determine the UPF network element corresponding to the first information based on the service type information in the first information, and send the first information to the UPF network element.

[0348] Step S2110: The UPF network element establishes a user plane connection with the first network element based on the first information.

[0349] For example, the first network element may be a CF network element. The UPF network element determines the CF network element corresponding to the first information based on the first information, and establishes a user plane connection between the UPF network element and the CF network element based on the first information. Based on the user plane connection, the CF network element can directly establish data communication with the UPF network element, so that the CF network element can directly call data in the UPF network element.

[0350] Step S2111, the UPF network element sends a second connection response message to the AMF network element based on the user plane connection.

[0351] For example, after the UPF network element establishes a user plane connection with the CF network element, it feeds back the second connection response information to the AMF network element to feed back the user plane connection status to the AMF network element.

[0352] In some embodiments, the name of the second connection response information is not limited, and it can be, for example, "user plane connection establishment response", "user plane establishment response", or "user plane connection response".

[0353] Step S2112: The AMF network element sends the first information to the second network node based on the second connection response information.

[0354] For example, after the AMF network element determines that a user plane connection is established between the UPF network element and the CF network element based on the second connection response information, the AMF network element sends the first information to the second network node, and the first information is used to instruct the second network node to establish a user plane connection with the UPF network element.

[0355] It should be noted that in this embodiment, the user plane connections established based on the same service request are identical. In the above embodiments, the user plane connection established between the CF network element and the DSF network element, the user plane connection established between the CF network element and the DCF network element, and the user plane connection established between the CF network element and the UPF network element all belong to the same user plane connection. Network elements within this user plane connection can communicate with each other. For example, the CF network element can communicate directly with the UPF network element, the CF network element can communicate directly with the DSF network element, and the UPF network element can send service data to the DSF network element for storage via the CF network element.

[0356] Step S2113: The second network node establishes a user plane connection with the UPF network element based on the first information, and sends a first connection response message to the AMF network element.

[0357] In some embodiments, the second network node may be a terminal, an access network device, a relay device, or the like, and may be a network node used to respond to a service request.

[0358] For example, after the second network node establishes a user plane connection with the UPF network element based on the first information, it can communicate data with the UPF network element, and after the second network node joins the user plane connection, it can feedback the first connection response information to the AMF network element. The first connection response information is used to indicate that a user plane connection has been established between the second network node and the core network device.

[0359] In some embodiments, the name of the first connection response information is not limited, and it can be, for example, "user plane connection establishment response", "user plane establishment response", or "user plane connection response".

[0360] Step S2114, the AMF network element sends a first connection response message to the third network element.

[0361] Step S2115: The third network element sends a first connection response message to the first network element.

[0362] For example, the first connection response information is used to indicate that a user plane connection has been established between the second network node and the core network device. After the AMF network element receives the first connection response information sent by the second network node, it sends the first connection response information to the first network element through the third network element, so that the first network element determines that the user plane connection is completed based on the first connection response information. The first network element can call each network element to collect data from the network node based on the user plane connection established between each network element and the network node in the above embodiment, for calculating the data operation result corresponding to the service request, and then send the data operation result to the first network node.

[0383] FIG2B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0384] Step S2201: The first network node sends a service request to the AMF network element.

[0385] In some embodiments, the first network node is configured to initiate a service request to a core network device. The service request may include data service requests in various large-scale data service scenarios, such as sensing service scenarios, positioning service scenarios, and AI (Artificial Intelligence) service scenarios. For example, based on the service request, the first network node requests the location information of the second network node from the core network device; based on the service request, the first network node requests AI prediction information from the core network device. Based on the service request, the core network device may need to schedule relevant data on the second network node to assist in calculating the AI ​​prediction information.

[0386] For example, in this embodiment, the core network device can judge the service request and determine whether it is necessary to build a user plane. If the service request requires scheduling multiple network elements and building a user plane for service data transmission, then the user plane is built based on the service request, and the large-scale data generated in the subsequent service request response process is transmitted according to the user plane.

[0387] In some embodiments, the first network node may be a terminal, an AF network element in a core network device, or an access network device, etc., which is a network node that initiates a service request. The first network node may also be an intermediate node for transmitting the service request, which is not limited in this embodiment.

The AMF network element performs access function management on the first network node based on the service request. When the first network node is authorized to access the core network based on the service request, the AMF network element determines the corresponding first network element based on the service request and sends the service request to the first network element. The first network element is a data computing function network element, which is used to calculate the large-scale data collected during the data service process to generate data calculation results. For example, the first network element is a CF network element.

[0393] For example, after the AMF network element in the core network device authorizes the first network node to access the core network device based on the service request, the AMF network element can determine the corresponding first network element according to the service request type. For example, if the service request is a location awareness request of the second network node, the AMF network element determines the first CF network element that can perform the awareness result calculation as the first network element based on the service request. The service request is sent to the first network element.

[0394] Step S2203: The first network element determines to adopt the user plane for data transmission based on the service request, and generates transmission rule information according to the service request.

The CF network element sends the first information to the AMF network element, and the data transmission is transferred through the AMF network element. The AMF network element sends the first information to the SMF network element.

[0421] Step S2207, the SMF network element determines the UPF network element corresponding to the first information and sends the first information to the UPF network element.

[0422] For example, one or more different types of UPF (User Plane Function) network elements can be configured in the core network device, and the UPF network element is used to implement different user functions. For example, the core network device includes: a perception function network element for perception, a function network element for performing AI model calculations, and a function network element for location determination. The SMF network element can determine the UPF network element corresponding to the first information based on the service type information in the first information, and send the first information to the UPF network element.

[0423] Step S2208: The UPF network element establishes a user plane connection with the first network element based on the first information.

[0424] For example, the first network element may be a CF network element. The UPF network element determines the CF network element corresponding to the first information based on the first information, and establishes a user plane connection between the UPF network element and the CF network element based on the first information. Based on the user plane connection, the CF network element can directly establish data communication with the UPF network element, so that the CF network element can directly call data in the UPF network element.

[0425] Step S2209, the UPF network element sends a second connection response message to the AMF network element based on the user plane connection.

[0426] In some embodiments, the name of the second connection response information is not limited, and it can be, for example, "user plane connection establishment response", "user plane establishment response", or "user plane connection response".

[0431] The optional implementation of step S2211 can refer to the optional implementation of step S2113 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0432] Step S2212, the AMF network element sends a first connection response message to the first network element.

[0433] For example, the first connection response information is used to indicate that a user plane connection has been established between the second network node and the core network device. After the AMF network element receives the first connection response information sent by the second network node, it sends the first connection response information to the first network element, so that the first network element determines that the user plane connection is completed based on the first connection response information.
