Specifically, this application does not make any limitations.

[0105] The network device 110 can be a device in a wireless network. For example, the network device 110 can be a device deployed in a radio access network to provide wireless communication functions for terminal devices. For example, the network device 110 can be a radio access network (RAN) node that connects the terminal device 120 to the wireless network, and can also be referred to as an access network device, RAN entity, access node, network node, or communication device, etc.

[0106] Specifically, the network device 110 can be an access network device for a cellular system related to the 3rd generation partnership project (3GPP). For example, a 4G communication system, a 5G communication system, etc. The network device 110 can also be an access network device in an open RAN (O-RAN or ORAN) or a cloud radio access network (CRAN). Or, the network device 110 can also be an access network device in a communication system obtained by fusing two or more of the above communication systems. Or, the network device 110 can also be a satellite in a satellite communication system.

For example, the next generation NodeB (gNB), TRP, TP in an NR system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or the network device 110 can also be a network node that constitutes a gNB or a transmission point. For example, centralized unit (CU), distributed unit (DU), centralized unit - control plane (CU - CP), centralized unit - user plane (CU - UP), or radio unit (RU), etc. The CU and DU can be set separately, or can also be included in the same network element, e.g., BBU. The RU can be included in a radio frequency device or radio frequency unit. For example, in a remote radio unit (RRU), active antenna unit (AAU), or remote radio head (RRH). Or, the network device 110 can also be a server, wearable device, vehicle, or in - vehicle device, etc. For example, the access network device in V2X technology can be a road side unit (RSU).

[0108] It should be noted that in different systems, the CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU may also be referred to as an open centralized unit (O-CU) or an open CU, the DU may also be referred to as an open distributed unit (O-DU), the CU-CP may also be referred to as an open centralized unit control plane (O-CU-CP), the CU-UP may also be referred to as an open centralized unit user plane (O-CU-UP), and the RU may also be referred to as an open radio unit (O-RU). The specific application of this application is not limited. Any one of the CU, CU-CP, CU-UP, DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0109] Optionally, for the network elements in the ORAN system, each network element can implement the protocol layer functions as shown in Table 1 below.

[0110] Table 1

[0111]

[0112]

[0113] It should be noted that in the ORAN system, the network device 110 in this application can be one or more of the network elements in Table 1 above.

[0114] The architectures of the CU and DU of the access network device are introduced below. The access network device includes at least one CU and at least one DU. Optionally, the access network device further includes at least one RU.

[0115] The following takes the access network device including a CU and a DU as an example for introduction. The CU has some functions of the core network. The CU may include a CU-CP and a CU-UP. The CU and the DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above (for example, the RRC layer and / or the SDAP layer). The DU is configured to implement the protocol layers below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the physical (PHY) layer). Another example is that the CU is configured to implement the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the protocol layers at and below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0116] When the CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane function of the CU, and the CU-UP is used to implement the user plane function of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, the RRC layer, and the SDAP layer, the CU-CP is used to implement the functions of the RRC layer and the control plane function of the PDCP layer, and the CU-UP is used to implement the functions of the SDAP layer and the user plane function of the PDCP layer.

[0117] The CU-CP can interact with the network element in the core network for implementing the control plane function. The network element in the core network for implementing the control plane function may be an access and mobility management function network element, such as the access and mobility management function (AMF) in the 5G system. The access and mobility management function network element is responsible for mobility management in the mobile network, such as location update of the terminal device, registration of the terminal device to the network, handover of the terminal device, etc.

[0118] The CU-UP can interact with the network element in the core network for implementing the user plane function. The network element in the core network for implementing the user plane function, for example, the user plane function (UPF) in the 5G system, is responsible for forwarding and receiving data in the terminal device.

[0119] The above configurations of the CU and DU are merely examples, and the functions of the CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layers. For example, some functions of the RLC layer and the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to service types or other system requirements. For example, divided by latency, the functions that require a small latency for processing time are set in the DU, and the functions that do not need to meet this latency requirement are set in the CU.

[0120] The DU and RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and RU can be configured in multiple ways according to the design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement mid-RF functions. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or implement the low-layer functions and RF functions. The high-layer functions in the physical layer can include a part of the functions of the physical layer, and this part of the functions is closer to the MAC layer. The low-layer functions in the physical layer can include another part of the functions of the physical layer, and this part of the functions is closer to the mid-RF side.

[0121] The network device 110 can also be a core network device. For example, the function entities of the control plane of the network device 110 include the access and mobility management function (AMF), or the session management function (SMF). The AMF is responsible for user access management, security authentication, mobility management, etc. The function entity of the data plane includes the UPF. The UPF is responsible for managing the transmission of user plane data, traffic statistics and other functions.

[0122] It should be noted that the network device 110 can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, chip system, module or control unit in the aforementioned shown device or apparatus. Specifically, the present application does not make a limitation. It should be noted that in the present application, when referring to the network device 110, it can refer to the network device 110 itself, or the chip, functional module or integrated circuit in the network device 110 that completes the method provided in the present application. Specifically, the present application does not make a limitation.

[0123] The AI module 130 refers to a device that runs an AI model to perform functions such as data collection, data processing, and model training. The AI module 130 can be a component in the network device 110, that is, the AI model is deployed in the network device 110. The AI module 130 can be a component in the terminal device 120, that is, the AI model is deployed in the terminal device 120. The AI module 130 can be an independent component, such as a network element in the core network, etc., and this component has the function of wireless communication, enabling the AI module 130 to communicate with the network device 110 and the terminal device 120 respectively. The AI model is a machine learning model applied in the field of artificial intelligence, capable of automatically learning and adapting to the patterns and rules of different data sets. The AI model can be trained on a large amount of data, learn features and relationships from it, and be used to solve various intelligent tasks. The AI model can be applied to multiple fields and tasks, such as natural language processing, computer vision, speech recognition, intelligent recommendation, etc. Common AI models can be neural network models (such as deep neural networks and recurrent neural networks), support vector machine models, decision tree models, etc. In the embodiments of the present application, the AI module 130 can perform functions such as data collection, data processing, and model training, so that the device to which the AI module 130 belongs has all or part of the AI functions.

[0124] In the embodiments of the present application, when the network device 110 does not have the AI service required by the terminal device 120, the network device 110 can maintain the relevant resources of one or more network elements that support the AI service (or AI function) through the core network. The core network constructs the AI service for the network device 110, enabling the network device 110 to provide the AI service for the terminal device 120. The core network is an important part of the mobile communication network, responsible for processing and managing user data, signaling, and control information in the mobile network. The core network is generally composed of multiple network elements, and the core network relies on each network element to achieve data processing, forwarding, and control.

[0125] The service generation system provided by the present application is run by the core network. The service generation system can build a specified target service by maintaining the relevant resources of the relevant network elements in the core network. The target service can refer to the above-mentioned AI service, or other types of services. The service generation system can maintain the relevant resources of one or more network elements of the target service, so that the network device 110 and the service generation system together can provide the target service for the terminal device 120. Among them, the target service can be services such as channel state information (CSI) compression feedback, performing cell reselection, cell selection, etc.

[0126] For ease of description, in this application, the relevant resources of one or more network elements that a service generation system needs to maintain to support one or more target services can be referred to as "service context".

[0127] Figure 2 This is a schematic diagram of an application scenario of a service generation system provided in an embodiment of this application. As Figure 2 shown, the service generation system 200 may include a service strategy network element 210, an AMF network element 220, a service-session management function (Service-SMF) network element 230, a service-user plane function (Service-UPF) network element 240, a database 250, and an over-the-top interface (OTT interface) 260.

[0128] Among them, the specific physical hardware of each network element of the service generation system 200 may be the above-mentioned network device 110, or the physical hardware of the above-mentioned terminal device 120, as well as other types of physical hardware. Optionally, the service generation system 200 may be the above-mentioned core network device. At this time, the service strategy network element 210, the AMF network element 220, and the Service-SMF network element 230 may be functional entities on the control plane of the core network device. The Service-UPF network element 240 and the database 250 are functional entities on the data plane of the core network device.

[0129] The service strategy network element 210 is used to make decisions on target services and can serve as the anchor node (or anchor network element) of the target service. The service strategy network element 210 can provide support for obtaining the target service context for services in the inactive state. In the embodiments of this application, the service strategy network element 210 can provide a decision-making function for AI services. Service strategies generally include maintaining relevant parameters of AI services, such as AI service identifiers, service context identifiers of AI services, node identifiers participating in AI services, node access addresses, regional descriptions of AI services, quality descriptions of AI services, etc.

[0130] The AMF network element 220 is used to control the connection between the core network and the terminal device 120 and mobility management. In the embodiments of this application, the AMF network element 220 can serve as a bridge between the terminal device 120 and the service generation system 200 to transmit data between the terminal device 120 and each network element of the service generation system 200.

[0131] The Service-SMF network element 230 is used to manage sessions related to target services, such as establishing and maintaining traffic channels for data transmission between various network elements related to target services such as data and models, and maintaining channel parameters (such as allocating IPs, channel addresses, etc.). In the embodiments of this application, the Service-SMF network element 230 can manage sessions related to AI services to establish and maintain traffic channels for data transmission between various network elements related to AI services, and maintain the allocated IPs, channel addresses, etc. of the traffic channels.

[0132] The Service-UPF network element 240 is used to provide user plane transmission for target services. In the embodiments of this application, the Service-UPF network element 240 can provide user plane transmission for AI services.

[0133] The database 250 may include a data pool 251, a model pool 252, and a computation pool 253. Among them, the data pool 251, the model pool 252, and the computation pool 253 may be located on one network element or other numbers of network elements.

[0134] The data pool 251 is used to maintain data such as data sets, intermediate results of training / inference, and corresponding identifiers. In the embodiments of this application, the data pool 251 can be used to maintain data such as data sets, intermediate results of training / inference of AI models, and service context identifiers.

[0136] The computation pool 253 is used to schedule the computing resources of each node in the network, support a certain service function, maintain computing resources and corresponding identifiers. In the embodiments of this application, the computation pool 253 can schedule the computing resources of each network element in the service generation system 200, support AI services, maintain the computing resources of AI services, and the identifiers of each resource.

[0137] The OTT interface 260 is used to provide interfaces for third-party data, models, etc., and maintain interface addresses, descriptions of incoming network traffic, etc.

[0138] Exemplarily, Figure 3Schematic diagram of the process of constructing a service context for the service generation system provided in the embodiments of the present application. It can be understood that the service context of the target service can be implemented by the network device 110, the terminal device 120, and the service generation system 200. The network elements involved in the service generation system 200 may include a service policy network element 210, an AMF network element 220, a Service-SMF network element 230, a Service-UPF network element 240, and a database 250. The specific process of the service generation system 200 constructing the service context of the target service is as follows:

[0139] Step S301, the terminal device 120 sends a first request instruction to the network device 110. The first request instruction is a service request instruction for requesting the target service supported by the network device 110.

[0140] Step S302, the network device 110 sends a first response instruction to the terminal device 120. The first response instruction is an instruction in response to the first request instruction, used to notify the terminal device 120 that the network device 110 supports the target service, or to notify the terminal device 120 that the network device 110 does not support the target service.

[0141] Optionally, in the ORAN system, the network device 110 in the above steps S301 - S302 may be the O-CU-CP network element, the O-DU network element, and / or the O-RU network element shown in Table 1 above.

[0142] When the terminal device 120 needs to execute the target service, it can send a first request instruction to the network device 110 to request the target service supported by the network device 110. After receiving the first request instruction, the network device 110 can determine whether it supports the target service locally according to the service context identifier carried in the first request instruction. In one case, when the network device 110 supports the target service, it can send a first response instruction to the terminal device 120 to notify the terminal device 120 that the network device 110 supports the target service. In another case, when the network device 110 does not support the target service, it can send a first response instruction to the terminal device 120 to notify the terminal device 120 that the network device 110 does not support the target service.

[0143] Step S303, the terminal device 120 sends a second request instruction to the AMF network element 220. The second request instruction is a service request instruction for requesting the support of the core network for the target service. In this embodiment, the second request instruction is used to request the target service supported by the service generation system 200.

[0144] Step S304: The AMF network element 220 sends a third request instruction to the service policy network element 210. The third request instruction is a service policy request instruction used to request the core network to generate a service policy for the target service. In this embodiment, the third request instruction is used to request the service policy network element 210 to generate a service policy for the target service.

[0145] Optionally, when the terminal device 120 sends the third request instruction to the AMF network element 220 through the network device 110 in the above step S303, the network device 110 may be the RAN.

[0146] When the terminal device 120 determines that the network device 110 does not support the target service, it may send a second request instruction to the AMF network element 220 through the network device 110. After receiving the second request instruction, the AMF network element 220 generates a third request instruction and sends the third request instruction to the service policy network element 210.

[0147] Step S305: The service policy network element 210 sends a fourth request instruction to the database 250. The fourth request instruction is a service configuration request instruction used to request the core network to provide relevant resources of each network element. In this embodiment, the fourth request instruction is used to request the database 250 in the service generation system 220 to provide the data pool 251, the model pool 252, and the computing pool 253.

[0148] Step S306: The database 250 sends a fourth response instruction to the service policy network element 210. The fourth response instruction is an instruction in response to the fourth request instruction, used to notify the core network that the provision of relevant resources of each network element is completed. In this embodiment, the fourth response instruction is used to notify the service policy network element 210 that the database 250 has configured the data pool 251, the model pool 252, and the computing pool 253.

[0149] The service policy network element 210 is the control center of the service generation system 200. After receiving the third request instruction, it can generate the service policy of the target service according to the third request instruction. After obtaining the service policy of the target service, the service policy network element 210 can configure the relevant resources of each network element in the service generation system 200 to support the target service. During the configuration process, the service policy network element 210 can send a fourth request instruction to the database 250, requesting the database 250 to provide the data pool 251, model pool 252, and computing pool 253 that support the target service. After receiving the fourth request instruction, the database 251 can create the data pool 251, model pool 252, and computing pool 253, and make the data pool 251 available for maintaining data such as data sets, intermediate results of model training / inference, and service context identifiers, make the model pool 252 maintain the model parameters, identifiers of the model, etc. of the target service, and make the computing pool 253 schedule the computing resources of each network element in the service generation system 200, support the target service, maintain the computing resources of the target service, and the identifiers of each resource. After completing the creation of the data pool 251, model pool 252, and computing pool 253, the database 250 sends a fourth response instruction to the service policy network element 210, notifying the service policy network element 210 that the database 250 has configured the data pool 251, model pool 252, and computing pool 253.

[0150] Step S307, the service policy network element 210 sends a fifth request instruction to the Service-SMF network element 230. The fifth request instruction is a request instruction for creating a traffic channel, used to request the core network to create a traffic channel for the relevant resources of each network element. In this embodiment, the fifth request instruction is used to request the Service-SMF network element 230 in the service generation system 220 to establish a traffic channel between the Service-UPF network element 240 for the local area, the terminal device 120, the service policy network element 210, the AMF network element 220, the data pool 251, the model pool 252, and the computing pool 253.

[0151] Step S308, the Service-SMF network element 230 sends a fifth response instruction to the service policy network element 210. The fifth response instruction is an instruction in response to the fifth request instruction, used to notify the core network that the creation of the traffic channel for the relevant resources of each network element is completed. In this embodiment, the fifth response instruction is used to notify the service policy network element 210 that the Service-SMF network element 230 has completed the creation of the traffic channel for the relevant resources of each network element.

[0152] After the service policy network element 210 creates the data pool 251, the model pool 252, and the computing pool 253, it can send a fifth request instruction to the Service-SMF network element 230, requesting the Service-SMF network element 230 to manage the relevant sessions of the target service. The Service-SMF network element 230 can create a traffic channel for network elements that need to perform traffic interaction, that is, establish a traffic channel between the network device 110, the AMF network element 220, the Service-SMF network element 230, the service policy network element 210, the data pool 251, the model pool 252, and the computing pool 253, so that the network device 110, the AMF network element 220, the Service-SMF network element 230, the service policy network element 210, the data pool 251, the model pool 252, and the computing pool 253 can perform traffic transmission with each other. The Service-SMF network element 230 can also establish a traffic channel between the terminal device 120 and the Service-UPF network element 240, so that the terminal device 120 and the Service-UPF network element 240 can perform traffic transmission, allowing the terminal device 120 to access other network elements in the service generation system 200 through the Service-UPF network element 240 and perform traffic transmission.

[0153] The Service-UPF network element 240 is a network element that performs traffic forwarding, so the traffic channels between the network device 110, the terminal device 120, the data pool 251, the model pool 252, and the computing pool 253 are all established on the Service-UPF network element 240. The Service-UPF network element 240 can forward the traffic of a network element at one end of the traffic channel to a network element at the other end, enabling communication between the two network elements.

[0154] After the Service-SMF network element 230 completes the establishment of the traffic channels between each network element, it can send a service session response instruction to the service policy network element 210, requesting the Service-SMF network element 230 to complete the establishment of the traffic channels between each network element. After receiving the service session response instruction, the service policy network element 210 determines that the relevant resource configurations of each network element for executing the target service are completed. The service policy network element 210 can generate a service context for the target service based on the relevant resources of each network element for executing the target service and store it in the local memory.

[0155] Step S309, the service policy network element 210 sends a third response instruction to the AMF network element 220. The third response instruction is an instruction in response to the third request instruction, used to notify the core network that the service context of the target service has been generated. In the embodiment, the third response instruction is used to notify the AMF network element 220 that the service policy network element 210 has completed the generation of the service context of the target service.

[0156] Step S310, the AMF network element 220 sends a second response instruction to the terminal device 120. The second response instruction is an instruction in response to the second request instruction, and is used to notify the terminal device 120 that the service generation system 200 supports the target service.

[0157] After the service policy network element 210 completes the generation of the service context of the target service, it can send a third response instruction to the AMF network element 220 to notify the AMF network element 220 that the service policy network element 210 has completed the generation of the service context of the target service. After receiving the third response instruction, the AMF network element 220 can convert it into a second response instruction to notify the terminal device 120 that the service generation system 200 supports the target service. After the terminal device 120 receives the second response instruction through the network device 110, it determines that the service generation system 200 has generated the service context of the target service, and can execute the target service in the service generation system 200 through the network device 110. If the terminal device 120 needs to execute the target service, it can send a sixth request instruction to the service generation system 200 through the network device 110. The sixth request instruction is used to request the service generation system 200 to execute the target service, so as to implement the service generation system 200 to provide the target service for the terminal device 120.

[0158] In the embodiment of the present application, when the network device 110 does not support the target service, the terminal device 120 can generate the service context of the target service through the service generation system 200, so that the network device 120 can implement the target service through the service generation system 200, ensuring the continuity of running the target service.

[0159] The states in which the service policy network element 210 supports the target service can include a service setup state, an inactive state, an active state, and a service release state. The service setup state refers to the state in which the service policy network element 210 coordinates the start-up parameters of each network element to start the target service. The start-up parameters can be the model scale, model input and output, service performance, etc. When the service policy network element 210 is in the service setup state, each network element has not yet generated the service context for implementing the target service.

[0160] The inactive state means that the service policy network element 210 puts the relevant resources of each network element of the target service in a dormant state. At this time, the service policy network element 210 can determine that each network element generates the service context according to the start-up parameters and stores it in the local memory. When the service policy network element 210 is in the inactive state, each network element will not provide the target service to the terminal device 120, and can let each network element update the service context. Among them, there are two ways for the service generation system 200 to cache the service context, which are respectively:

[0161] The service policy network element 210 can centrally store the service contexts of each network element supporting the target service in the local storage, so that each network element does not need to cache the service context. When the target service enters the active state, the service policy network element 210 can distribute the stored service contexts to each network element for each network element to load and run.

[0162] The service policy network element 210 can instruct each network element supporting the target service to cache the service context locally, so that the service context is distributed and stored in each network element. When the target service enters the active state, the service policy network element 210 can instruct each network element to load and run.

[0163] The active state refers to the state in which the service policy network element 210 starts the target service based on the service context. At this time, the service policy network element 210 can cause the terminal device 120 to execute the target service and can cause each network element to update the service context.

[0164] The service release state refers to the state in which the service policy network element 210 causes each network element to cancel the service context of the target service.

[0165] The service policy network element 210 supports the mutual conversion between various states of the target service. As Figure 4 shown, the service generation state and the inactive state of the service policy network element 210 can be mutually converted, the service generation state and the active state of the service policy network element 210 can be mutually converted, the inactive state and the active state of the service policy network element 210 can be mutually converted, the service generation state of the service policy network element 210 can be switched to the service release state, the inactive state of the service policy network element 210 can be switched to the service release state, and the active state of the service policy network element 210 can be switched to the service release state.

[0166] In the embodiment of the present application, when the terminal device 120 determines that the network device 110 does not support the target service, the service context supporting the target service can be constructed through the network device 110. After receiving the first request instruction, the network device 110 first aligns the parameters of the network device 110 and each network element of the core network to ensure the normal operation and coordinated operation of the network device 110 and each network element of the core network.

[0167] Figure 5 It is a schematic flow chart of generating a service context by the network device provided in the embodiment of the present application. As Figure 5 shown, the network device 110 generally cooperates with the terminal device 120 and the core network to generate a service context, and the specific implementation process is as follows:

[0168] Step S501, the terminal device 120 sends a first request instruction to the network device 110. The first request instruction is a service request instruction for requesting the target service supported by the network device 110.

[0169] Step S502, the network device 110 detects whether there is a service context of the target service locally. In one case, the network device 110 determines that there is no service context of the target service locally and executes Step S503. In another case, the network device 110 determines that there is a service context of the target service locally and executes Step S506.

[0170] After receiving the first request instruction sent by the terminal device 120, the network device 110 can detect whether there is a service context corresponding to the service context identifier carried in the first request instruction locally. In one case, when the network device 110 determines that there is a service context corresponding to the service context identifier locally, it can determine the service context of the target service. In another case, when the network device 110 determines that there is no service context corresponding to the service context identifier locally or there is no complete service context corresponding to the service context identifier locally, it can forward the first request instruction to the core network or send a seventh request instruction to the core network to request the service function information of each network element that supports the target service provided by the core network.

[0171] Step S503, the network device 110 sends the first request instruction or the seventh request instruction to the core network. The seventh request instruction is a request instruction for obtaining service function information and is used to request the core network to provide the service function information of the target service.

[0172] Step S504, the core network sends the service function information to the network device 110.

[0173] If the network device 110 receives the first request instruction, it can directly pass the first request instruction through to the core network. If the network device 110 receives the seventh request instruction, the network device 110 can send the seventh request instruction to the core network through the RAN. Inside the core network, the first request instruction and the seventh request instruction have the same function, which is to obtain the service function information of the target service. The core network can be the above-mentioned service generation system 200. The service generation system 200 can forward the first request instruction or the seventh request instruction to the service policy network element 210. The service policy network element 210 can determine the service function information of each network element according to the service context identifier carried in the first request instruction or the seventh request instruction, and send the service function information to the network device 110. The service function information includes the service types and / or function types that each network element supporting the target service can provide. The service types can be service types such as training, inference, data collection, etc. The function types can be enabling features of the target service such as channel estimation, beam management, mobility management, etc.

[0174] Step S505, the network device 110 generates all or part of the service context of the target service according to the service function information.

[0175] Step S506, the network device 110 sends a first response instruction to the terminal device 120. The first response instruction is an instruction in response to the first request instruction, and is used to notify the terminal device 120 that the network device 110 supports the target service.

[0176] After the network device 110 obtains the service types and function types that each network element of the core network can provide, it can locally configure the service parameters of the target service, such as the configuration of the model, the configuration of the data set, computing resources, parameter version numbers, running environment information, etc. The network device 110 can generate all or part of the service context of the target service according to the service parameters of the target service and the service context identifier carried in the first request instruction, and set the state of the service context of the target service to the inactive state. If the service context generated by the network device 110 is part of the service context of the target service, then the part of the service context of the target service refers to the relevant resources participated by the network device 110 that supports the target service.

[0177] After the network device 110 generates the service context of the target service, it can send a first response instruction to the terminal device 120. After receiving the first response instruction, the terminal device 120 determines that the network device 110 has generated the service context of the target service and can execute the target service in the network device 110 and / or the core network. If the terminal device 120 needs to execute the target service, it can send an eighth request instruction to the core network through the network device 110. The eighth request instruction is used to request the network device 110 and / or the core network to execute the target service, so as to enable the network device 110 to provide the target service for the terminal device 120. At this time, the network device 110 sets the service context of the target service to the active state.

[0178] After the network device 110 generates the support for the target service, it can broadcast or multicast system messages. The system messages are used to indicate the target services supported by the network device 110. The system messages include the relevant configuration information of the target services. The configuration information may include the identification (ID) of the target service, the mapping configuration of the logical traffic channel (LTCH) for carrying the service traffic of the target service and the physical downlink shared channel (PDSCH) and / or the physical uplink shared channel (PUSCH), and the configuration information of each protocol layer.

[0179] After receiving the system messages, the terminal device 120 can determine whether it needs the target service of the network device 110 according to local requirements. If the terminal device 120 needs the target service of the network device 110, it can send interest information to the network 110 to inform the network device 110 that the terminal device 120 needs the target service of the network device 110. After receiving the interest information, the network device 110 can know the target service of the terminal device 120 to identify the corresponding model and / or function of the target service and set the target service to the active state, so that the terminal device 120 can execute the target service through the network device 110.

[0180] Optionally, in the ORAN system, the network device 110 in the above steps S501 - S506 may be the O-CU-CP network element, the O-DU network element, and / or the O-RU network element shown in Table 1 above.

[0181] In an embodiment of the present application, a regional identifier may be added to the service context in which the network device 110 participates. The regional identifier is used to distinguish the geographical area where the service context takes effect, and may be the ID of the network device 110, the address of the area where the network device 110 is located, or other identifiers that distinguish the network device 110. The network device 110 may locally construct a dedicated service context based on the regional identifier and the service context identifier. The terminal device 120 generally carries the service context identifier (i.e., the service context ID) of the target service to be executed. After the terminal device 120 switches from one network device 110 to another network device 110, it sends the service context identifier to the switched-to network device 110. After receiving the service context identifier, the network device 110 determines the service context corresponding to the service context identifier, and determines whether the regional identifier in the service context corresponding to the service context identifier is the same as the local regional identifier. If the network device 110 determines that the regional identifier in the service context corresponding to the service context identifier is different from the local regional identifier, the service context for providing the target service locally changes. The network device 110 discovers that the regional identifier has changed, and confirms that the service context it holds locally is not suitable for providing the target service to the newly arrived terminal device 120.

[0182] After the network device 110 determines that the service context for providing the target service to the terminal device 120 has changed, it may send a ninth request instruction to the terminal device 120. The ninth request instruction is used to request the terminal device 120 to determine whether the network device 110 regenerates the service context of the target service. After receiving the ninth request instruction, the terminal device 120 may resend the first request instruction, the second request instruction, or other request instructions to the switched-to network device 110, requesting the switched-to network device 110 to regenerate the service context of the target service, and requesting the switched-to network device 110 to regenerate the service context of the target service in other ways, so that the terminal device 120 can execute the target service through the switched-to network device 110. Alternatively, the terminal device 120 sends a pause instruction to the switched-to network device 110, instructing the switched-to network device 110 to pause maintaining the service context and causing the terminal device 120 to stop executing the target service.

[0183] When the terminal device 120 switches from one network device 110 to another network device 110, it can send the service context identifier to the switched-to network device 110. After receiving the service context identifier, the switched-to network device 110 determines whether there is a service context corresponding to the service context identifier locally. In one case, if the switched-to network device 110 has the corresponding service context, it can add the terminal device 120 to the service session maintained by the local service context. In another case, if the switched-to network device 110 does not have the corresponding service context, it can broadcast or multicast the corresponding service context identifier to other network devices 110 to find a network device 110 that has the corresponding service context. After the switched-to network device 110 finds a network device 110 that has the corresponding service context, it can obtain the corresponding service context from the other network device 110 and set the state of the corresponding service context to the active state. The switched-to network device 110 can add the terminal device 120 to the service session maintained by the local service context, so that the terminal device 120 can execute the target service through the switched-to network device 110.

[0184] According to the local resource status, the switched-to network device 110 can configure a unicast link for the terminal device 120, or add the terminal device 120 to an existing multicast or broadcast link, so as to configure radio access network resources for the terminal device 120 to carry the traffic of the transmission service. During the process of the terminal device 120 switching from one network device 110 to another network device 110, it can obtain the service context from the network according to the service context identifier to ensure the continuity of the terminal device 120 running the target service.

[0185] Figure 6 It is a schematic flowchart of the process for the network device to update the service context provided in the embodiments of this application. As Figure 6 shown, the process for the network device 110 to update the service context is specifically as follows:

[0186] Step S601, the network device 110 sends a tenth request instruction to the terminal device 120. The tenth request instruction is a service query request instruction used to request to query the service context in the terminal device 120.

[0187] Step S602, the terminal device 120 sends a tenth response instruction to the network device 110. The tenth response instruction is an instruction in response to the tenth request instruction, used to provide the service context identifier that the terminal device 120 needs to update. The tenth response instruction includes the service context identifier that the terminal device 120 needs to update.

[0188] After the network device 110 needs to update the service context maintained locally, it can initiate the update function of the service context and send a tenth request instruction to the terminal device 120 to request querying the service context in the terminal device 120. After receiving the tenth request instruction, the terminal device 120 can send a tenth response instruction to the network device 110 according to the service context that needs to be updated. The tenth response instruction carries the service context identifier that the terminal device 120 needs to update, so that after the network device 110 receives the tenth response instruction, it can obtain the service context that the terminal device 120 needs to update. The tenth response instruction also carries the status information of the target service, so that after the network device updates the service context, it can set the updated service context to the corresponding status according to the status information.

[0189] Step S603, the network device 110 detects whether there is a service context corresponding to the service context identifier carried in the tenth response instruction locally. In one case, the network device 110 determines that there is a service context corresponding to the service context identifier carried in the tenth response instruction locally, and executes step S606. In another case, the network device 110 determines that there is no service context corresponding to the service context identifier carried in the tenth response instruction locally, and executes step S604.

[0190] Step S604, the network device 110 sends an eleventh request instruction to the anchor node. The anchor node refers to the network device 110 that can construct the service context corresponding to the service context identifier. The eleventh request instruction is used to request other network devices to provide the service context corresponding to the service context identifier carried in the tenth response instruction.

[0191] Step S605, the anchor node sends an eleventh response instruction to the network device 110. The eleventh response instruction is an instruction in response to the eleventh request instruction, and is used to provide the service context corresponding to the service context identifier carried in the tenth response instruction. The eleventh response instruction includes the service context corresponding to the service context identifier carried in the tenth response instruction.

[0192] After receiving the tenth response instruction, the network device 110 can detect whether there is a corresponding service context locally according to the service context identifier carried in the tenth response instruction. In one case, when the network device 110 determines that there is a service context corresponding to the service context identifier carried in the tenth response instruction locally, it can maintain the service context corresponding to the service context identifier. In another case, when the network device 110 determines that there is no service context corresponding to the service context identifier carried in the tenth response instruction locally or there is no complete service context corresponding to the service context identifier carried in the tenth response instruction, it can broadcast an eleventh request instruction to other network devices 110, requesting other network devices 110 to provide the service context corresponding to the service context identifier carried in the tenth response instruction. The eleventh request instruction carries the service context identifier carried in the tenth response instruction so that other network devices 110 can provide the corresponding service context.

[0193] After other network devices 110 determine that there is a service context corresponding to the service context identifier carried in the tenth response instruction locally according to the service context identifier carried in the tenth response instruction, they can send an eleventh response instruction to the network device 110, and send the service context corresponding to the service context identifier carried in the tenth response instruction to the network device 110.

[0194] Step S606, the network device 110 updates the service context.

[0195] After the network device 110 obtains the service context corresponding to the service context identifier carried in the tenth response instruction, it can maintain the corresponding service context and set the state of the service context to the state indicated by the status information carried in the tenth response instruction, so as to update the service context.

[0196] Optionally, in the ORAN system, the network device 110 in the above steps S601 - S605 may be the O-CU-CP network element, O-DU network element, and / or O-RU network element shown in Table 1 above.

[0197] Next, taking CSI compression feedback as an example, an implementation scenario of the solution of the embodiment of the present application will be introduced.

[0198] Figure 7 It is a schematic flowchart of the process of constructing the CSI compression feedback function for the terminal device, network device, and service generation system provided in the embodiment of the present application. As Figure 7 shown, the process of constructing the CSI compression feedback function for the terminal device 120, network device 110, and service generation system 200 is specifically as follows:

[0199] Step S701: The terminal device 120 sends a twelfth request instruction to the network device 110. The function of the twelfth request instruction can be similar to that of the first request instruction, and is used to request the CSI compression feedback function supported by the network device 110.

[0200] CSI compression feedback means that in a wireless communication system, CSI information is compressed by a certain method to reduce the resource overhead required for CSI feedback. When the terminal device 120 needs the CSI compression feedback function, it can send a twelfth request instruction to the network device 110 to request the network device 110 to maintain the service context of the CSI compression feedback function.

[0201] Step S702: The network device 110 sends a thirteenth request instruction to the service generation system 200. The function of the thirteenth request instruction can be similar to that of the seventh request instruction, and is used to request to obtain the service function information of the service generation system 200 that supports the CSI compression feedback function.

[0202] Step S703: The service generation system 200 sends a thirteenth response instruction to the network device 110. The function of the thirteenth request instruction can be similar to that of the service function information, and carries the service function information of the CSI compression feedback function supported.

[0203] Similarly, the specific implementation process of steps S701 - S703 can refer to Figure 5 the process of steps S501 - S504 in, specifically: after receiving the twelfth request instruction, the network device 110 first detects whether there is a service context of the CSI compression feedback function locally. In one case, the network device 110 determines that there is a service context of the CSI compression feedback function locally and does not need to execute steps S702 - S703. In another case, the network device 110 determines that there is no service context of the CSI compression feedback function locally, and can send a thirteenth request instruction to the service generation system 200 to obtain the service function information of the service generation system 200 that supports the CSI compression feedback function. After receiving the thirteenth request instruction, the service generation system 200 determines the service function information of each network element that supports the CSI compression feedback function according to the service context identifier carried in the thirteenth request instruction, and sends the service function information to the network device 110.

[0204] Step S704: The network device 110 generates the CSI compression feedback function.

[0205] Step S705: The network device 110 updates the local service context.

[0206] After obtaining the service function information of the service generation system 200, the network device 110 can locally configure the service parameters of the CSI compression feedback function. The network device 110 can generate all or part of the service context of the CSI compression feedback function according to the service parameters of the CSI compression feedback function and the service context identifier of the CSI compression feedback function carried in the twelfth request instruction, and maintain the service context of the CSI compression feedback function, so that the network device 110 supports the CSI compression feedback function. At this time, the network device 110 can set the state of the service context of the CSI compression feedback function to the inactive state.

[0207] Step S706, the network device 110 sends a twelfth response instruction to the terminal device 120. The function of the twelfth response instruction can be similar to that of the first response instruction, and is used to notify the terminal device 120 that the network device 110 supports the CSI compression feedback function.

[0208] After obtaining the service context of the CSI compression feedback function, the network device 110 can maintain the service context of the CSI compression feedback function and execute the CSI compression feedback function to ensure the continuity of the operation of the CSI compression feedback function of the terminal device 120. After the network device 110 has the CSI compression feedback function, it can send a twelfth response instruction to the terminal device 120 to inform the terminal device 120 that the current network device 110 has the CSI compression feedback function.

[0209] Step S707, the network device 110 activates the CSI compression feedback function.

[0210] After the terminal device 120 determines that the network device 110 has the CSI compression feedback function, it can send an execution instruction to the network device to implement the CSI compression feedback function through the network device 120 and / or the service generation system 200. At this time, the network device 110 can set the state of the service context of the CSI compression feedback function to the active state, so that the CSI compression feedback function operates normally.

[0211] Optionally, in the ORAN system, the network device 110 in the above steps S701 - S707 can be the O-CU-CP network element, O-DU network element, and / or O-RU network element shown in Table 1 above.

[0212] In other embodiments, the function of the twelfth request instruction can be similar to that of the second request instruction, and is used to request the service generation system 200 to support the CSI compression feedback function. At this time, the network device 110 only forwards the twelfth request instruction, that is, the thirteenth request instruction and the twelfth request instruction are one request instruction.

[0213] After receiving the thirteenth request instruction, the service generation system 200 can generate a service context that supports the CSI compression feedback function. The specific implementation process can refer to Figure 3 the process of steps S305 - S309 in

[0214] Specifically, for example, the service generation system 200 may include a service policy network element 210, an AMF network element 220, a Service - SMF network element 230, a Service - UPF network element 240, and a database 250. The service policy network element 210 generates a service policy for the CSI compression feedback function according to the service context identifier carried in the third request instruction. The service policy network element 210 may send a fourth request instruction to the database 250, requesting the database to provide a data pool 251, a model pool 252, and a computing pool 253 that support the target service. After receiving the fourth request instruction, the database 251 can create the data pool 251, the model pool 252, and the computing pool 253.

[0215] After the service policy network element 210 creates the data pool 251, the model pool 252, and the computing pool 253, it requests the Service - SMF network element 230 to manage the relevant sessions for the CSI compression feedback function. The Service - SMF network element 230 can establish traffic channels between the network device 110, the AMF network element 220, the Service - SMF network element 230, the service policy network element 210, the data pool 251, the model pool 252, and the computing pool 253, enabling traffic transmission between them, and establish a traffic channel between the terminal device 120 and the Service - UPF network element 240, enabling traffic transmission between the terminal device 120 and the Service - UPF network element 240. The service policy network element 210 can generate a service context for the CSI compression feedback function based on the relevant resources of each network element that executes the CSI compression feedback function and send it to the network device 110.

[0216] At this time, the thirteenth response instruction is used to request the service generation system 200 to support the CSI compression feedback function, and then the network device 110 directly executes steps S706 - S707. Figure 6The process of steps S603 - S605. At this time, the thirteenth response instruction carries a service context that supports the CSI compression feedback function, and then the network device 110, the terminal device 120, and the service generation system 200 directly execute steps S704 - S707.

[0217] In the embodiments of the present application, when the terminal device 120 executes the CSI compression feedback function through the network device 110, in the case where the network device 110 does not support the CSI compression feedback function, a service context for the CSI compression feedback function can be constructed through the network device 110 and / or the service generation system 200. After obtaining the service context for the CSI compression feedback function, the network device 110 can support the CSI compression feedback function to ensure the continuity of the operation of the CSI compression feedback function of the terminal device 120.
