[0205] With the commercial deployment of 5G (5th Generation Mobile Networks, the fifth generation mobile communication system), research on 6G (6th Generation Mobile Networks, the sixth generation mobile communication system) is actively carried out, and there are many guesses about the 6G network architecture. The following will introduce several guesses about the 6G network architecture in combination with the figure.

[0206] Referring to FIG. 1, FIG. 1 is a logical architecture diagram of a 6G multi-dimensional fusion network.

[0207] In FIG. 1, in the transverse logic, the 6G network can be divided into a resource layer, a network function layer, and an application and service layer. Among them, the resource layer provides underlying resources such as wireless, computing, and storage, and provides corresponding support and services for the function generation of the network function layer. The network function layer forms a specific network function, or combines one or more network functions together, to provide the most basic network service capability to meet the needs of the application and service layer. The application and service layer provides corresponding support for customers' business and applications, and realizes service customization.

[0208] In the longitudinal logic, in addition to the "communication surface" carrying the traditional communication business, the 6G network will add a data surface, a computing surface, an intelligent surface and a management surface. Among them, the data surface is responsible for the collection, cleaning, processing and storage of data in the end-to-end network, and provides data services to other layers and surfaces. The computing surface provides a unified computing power warehouse, senses computing power demand, orchestrates computing tasks, provides computing power routing, computing power modeling and state sensing, and provides computing services to other layers and surfaces. The intelligent surface provides a complete operating environment required for the whole life cycle of endogenous AI (Artificial Intelligence), and the intelligent surface calls services provided by the data surface and the computing surface to provide intelligent services to other layers and surfaces. The management surface is to manage all other layers and surfaces.

[0209] Referring to FIG. 2, FIG. 2 is a 6G network architecture.

[0210] In FIG. 2, the open enabling layer is used to provide computing power services, connection services, function services, data services, AI services and security services. The service-oriented function layer includes "five surfaces": the control surface, the user surface, the data surface, the intelligent surface and the security surface. The routing and connection layer is used for networking connection, signaling routing, full-service call, stateless transmission, deterministic forwarding, network state sensing, secure connection, wireless Qos (Quality of Service) connection and provision of simple protocols.

[0211] Referring to FIG. 3, FIG. 3 is a 6G network architecture, which includes three layers and three surfaces.

[0212] The 6G network architecture in FIG. 3 proposes the concept of "ubiquitous super-convergence", which absorbs the IT (Internet Technology) idea and takes new network virtualization as the core. The goal is to realize the convergence of multi-dimensional resources such as ubiquitous computing, storage, network and security in the same architecture system, the convergence of various information infrastructures such as network infrastructure, cloud infrastructure, computing power infrastructure and blockchain infrastructure, and the extensive convergence of emerging technologies such as artificial intelligence, big data and digital twin. Finally, endogenous genes are built to realize the integrated provision of cloud, computing, data, network and other resources and service capabilities, and to support the innovative development of future business applications.

[0213] Among them, the "three layers" respectively refer to the ubiquitous cloud network infrastructure layer, the convergence orchestration management layer and the agile business service layer, and the "three surfaces" are to realize network endogenous genes by using emerging technologies on the basis of cross-layer unification, including digital twin, intelligent endogenous and endogenous security.

[0214] The ubiquitous cloud network facility layer as the New Underlay layer will provide more extensive network connection and information infrastructure resource integration. The integration orchestration management layer as the New Hypervisor layer mainly realizes multi-dimensional resource atomization capability abstraction and integration orchestration, that is, on the basis of integration of computing, storage and network resources, a new digital platform is constructed to realize end-to-end service orchestration, decentralized resource trading, business automatic opening, full life cycle management and capability ecological opening. The agile business service layer as the New Overlay layer provides application-level fast connection.

[0215] Referring to FIG. 4, FIG. 4 is a “three-layer three-domain two-chain” 6G network architecture, which includes three layers, three domains and two chains.

[0216] The three layers in the vertical direction, the three domains in the horizontal direction and the two chains in FIG. 4, from the spatial dimension of network connection, the future 6G network will be a full-dimensional natural space fusion of three-layer networks of ground communication, space-based communication and space-based communication, providing a network of full-domain ubiquitous connection services. From the perspective of specific functions, the future 6G network architecture should include specific function domains such as perception resource domain, function control domain and service application domain. In view of the capability requirements of users and businesses for the network, as well as the capability requirements of network operation for the network, intelligent native and secure and reliable will become the core genetic chain of the future 6G network, conveying and expressing the evolution characteristics of the 6G network.

[0217] In other speculations, a 6G network architecture including three layers and five faces is also proposed, the three layers include infrastructure layer, network function layer and capability and service opening layer, and the five faces include enabling face, control face, forwarding face, orchestration management face and data face, wherein the enabling face includes endogenous computing power, security and intelligent capability.

[0218] The above preliminary assumptions about the 6G network architecture increase other function faces on the basis of the control face and the user face, which will certainly bring about changes in the network protocol stack of the UE (User Equipment), RAN (Radio Access Network) and CN (Core Network), in order to complete the entire business process of the UE.

[0219] However, at present, only preliminary assumptions about the 6G network architecture are proposed. Taking the intelligent face as an example, after the introduction of the intelligent face, how to design the network protocol stack becomes a problem to be solved at present.

[0220] In view of this, some embodiments of the present disclosure provide a network protocol stack, a transmission method and device, a base station, a UE and a network function, which solve the design problem of the network protocol stack after the introduction of the intelligent face.

[0221] The technical solutions of the present disclosure and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present disclosure will be described below with reference to the drawings.

[0222] In some embodiments, as shown in FIG. 5, a network protocol stack is provided, which is arranged at a base station, and the network protocol stack includes a first air interface protocol layer and a first AICP (Artificial Intelligence Control Protocol) layer.

[0223] In a possible implementation, the first air interface protocol layer can be a current air interface protocol layer. For example, as shown in FIG. 6, the first air interface protocol layer includes a first physical layer (PHY), a first media access control layer (MAC), a first radio link control layer (RLC), and a first packet data convergence protocol layer (PDCP).

[0224] In another possible implementation, the first air interface protocol layer can also not be a current air interface protocol layer, but other newly designed air interface protocol layers. For example, as shown in FIG. 7, the first air interface protocol layer is assumed to be named as L1 layer and L2 layer, and the specific functions of the L1 layer and the L2 layer are not limited.

[0225] In some embodiments of the present disclosure, the first AICP layer is carried on the first air interface protocol layer. Taking the example that the first air interface protocol layer is a current air interface protocol layer, the first AICP layer is carried on the first packet data convergence protocol layer (the PDCP layer shown in FIG. 6).

[0226] In addition to being used for transmitting signaling and data of traditional communication services, the first air interface protocol layer is also used for receiving AI requests sent by the UE and transmitting the AI requests to the first AICP layer for the intelligent surface.

[0227] Exemplarily, continuing to take the first air interface protocol layer shown in FIG. 6 as an example, the first air interface protocol layer includes a first physical layer (PHY shown in FIG. 6) that receives the AI request sent by the UE, which reaches the first AICP layer after sequentially passing through a first medium access control layer (MAC shown in FIG. 6) included in the first air interface protocol layer, a first radio link control layer (RLC shown in FIG. 6) included in the first air interface protocol layer, and a first packet data convergence protocol layer (PDCP shown in FIG. 6) included in the first air interface protocol layer.

[0228] In this way, the configuration of the first AICP layer based on the current air interface protocol stack can design the protocol stack of the intelligent surface without modifying the current air interface protocol stack, thereby greatly utilizing the existing air interface protocol stack between the UE and the base station, avoiding significant modification of the air interface protocol stack, and reducing the implementation difficulty of the network protocol stack of some embodiments of the present disclosure.

[0229] In some embodiments of the present disclosure, the AI request includes an AI service related request and / or an AI mobility request. The AI service related request includes at least one of the following: AI control signaling, and uplink AI service data.

[0230] The AI control signaling may, for example, be a related control request of the AI service, such as a service establishment request, a service modification request, etc., and the uplink AI service data may be related data of the AI service sent by the UE. The AI mobility request refers to a request related to intelligent surface mobility management, and the first AICP layer transmits the AI mobility request. The transmission process of the first AICP layer will be described in the embodiments below.

[0231] After the first air interface protocol layer transmits the AI request sent by the UE to the first AICP layer, the first AICP layer is configured to transmit the AI request to the core network. Exemplarily, the base station further includes a protocol stack between the base station and the core network, which can be a point-to-point interface or a service interface, etc., and can be configured according to different application scenarios. The first AICP layer transmits the AI request to the protocol stack included in the base station and transmits the AI request to the core network by the protocol stack.

[0232] Exemplarily, the first AICP layer can transmit different AI requests to corresponding network functions in the core network.

[0233] The above embodiment sets the first AICP layer on the first air interface protocol layer, the first air interface protocol layer transmits signaling and data of a traditional communication service, and the first AICP layer transmits an AI request of an intelligent surface, the AI request including an AI service related request and / or an AI mobility request, thereby realizing the functions of the network protocol stack for the traditional communication service and for the intelligent surface, and solving the design problem of the network protocol stack after the introduction of the intelligent surface.

[0234] The first AICP layer introduced above can be a protocol layer carried above the first air interface protocol layer, the first AICP layer having the functions of transmitting AI signaling (AI control signaling) and AI service data (such as the uplink AI service data mentioned above), and the first AICP layer can also transparently transmit an AI mobility request.

[0235] In other possible implementations, referring to FIG. 8, the first AICP layer includes a first AICP-C (Control) layer and a first AICP-U (User) layer, the first AICP-C layer being carried above the first air interface protocol layer, and the first AICP-U layer being carried above the first air interface protocol layer.

[0236] That is, the first AICP layer can also be split into two layers: the first AICP-C layer and the first AICP-U layer, the first AICP-C layer and the first AICP-U layer having different functions, the first AICP-C layer being used to transmit AI control signaling and AI mobility requests to the core network, and the first AICP-U layer being used to transmit uplink AI service data to the core network.

[0237] Continuing with the example of the first air interface protocol layer shown in FIG. 6, the first physical layer (PHY shown in FIG. 6) included in the first air interface protocol layer receives an AI request (including one or more of AI control signaling, AI mobility requests, and uplink AI service data) sent by the UE, the AI request passing through the first media access control layer (MAC shown in FIG. 6) included in the first air interface protocol layer, the first radio link control layer (RLC shown in FIG. 6) included in the first air interface protocol layer, and the first packet data convergence protocol layer (PDCP shown in FIG. 6) included in the first air interface protocol layer in sequence. On the one hand, the first packet data convergence protocol layer transmits AI control signaling and AI mobility requests to the first AICP-C layer, and the first AICP-C layer transmits the AI control signaling and the AI mobility requests to the corresponding network function in the core network. On the other hand, the first packet data convergence protocol layer transmits uplink AI service data to the first AICP-U layer, and the first AICP-U layer transmits the uplink AI service data to the corresponding network function in the core network.

[0238] In this way, the first AICP layer can be a layer in the network protocol stack, and can also be split into two layers according to functions, thereby improving the setting flexibility of the network protocol stack of some embodiments of the present disclosure.

[0239] Please continue to refer to FIG. 8, and the above introduces that the first AICP-U layer can transmit the uplink AI service data of the UE to the corresponding network function in the core network, and in some embodiments of the present disclosure, the first AICP-U layer is also used for receiving the downlink AI service data sent by the core network. As mentioned above, the base station also includes a protocol stack between the base station and the core network, which receives the downlink AI service data sent by the core network, and transmits the downlink AI service data to the first AICP-U layer. The first AICP-U layer transmits the downlink AI service data to the first air interface protocol layer, and the first air interface protocol layer transmits the downlink AI service data to the UE.

[0240] In this way, the AICP layer is introduced between the UE and the base station, and in some embodiments, the first AICP layer in the base station is split into the first AICP-C layer and the first AICP-U layer according to functions. The first AICP-C layer transmits the AI control signaling between the UE and the base station, and the first AICP-U layer transmits the AI service data between the UE and the base station. The first AICP-C layer can also transparently transmit the AI mobility request between the UE and the core network, thereby solving the design problem of the network protocol stack after introducing the intelligent surface.

[0241] It should be noted that if the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, referring to the embodiment shown in FIG. 5, the first AICP layer is also used for receiving the downlink AI service data sent by the core network. The first AICP layer transmits the downlink AI service data to the first air interface protocol layer, and the first air interface protocol layer transmits the downlink AI service data to the UE. That is, the first AICP layer transmits the AI control signaling between the UE and the base station, and transmits the AI service data between the UE and the base station. The first AICP layer can also transparently transmit the AI mobility request between the UE and the core network, thereby also solving the design problem of the network protocol stack after introducing the intelligent surface.

[0242] In some embodiments, as shown in FIG. 9, a network protocol stack is provided, which is arranged in the UE, and the network protocol stack includes a second air interface protocol layer and a second AICP layer.

[0243] Similar to the first air interface protocol layer, the second air interface protocol layer can be a current air interface protocol layer. For example, as shown in FIG. 10, the second air interface protocol layer includes a second physical layer (PHY shown in FIG. 10), a second medium access control layer (MAC shown in FIG. 10), a second radio link control layer (RLC shown in FIG. 10), and a second packet data convergence protocol layer (PDCP shown in FIG. 10).

[0244] In another possible implementation, the second air interface protocol layer can also not be the current air interface protocol layer, but another newly designed air interface protocol layer. For example, as shown in FIG. 11, the second air interface protocol layer includes an L1 layer and an L2 layer, and the specific functions of the L1 layer and the L2 layer are not limited.

[0245] In some embodiments of the present disclosure, the second AICP layer is carried on the second air interface protocol layer. For example, when the second air interface protocol layer is the current air interface protocol layer, the second AICP layer is carried on a second packet data convergence protocol layer (for example, the PDCP layer shown in FIG. 10).

[0246] Referring to FIG. 12, the second AICP layer in the UE transmits an AI service related request of the UE to the second air interface protocol layer in the UE, and the AI service related request includes at least one of the following: AI control signaling, uplink AI service data, and related concepts of the AI control signaling and the uplink AI service data, which can be referred to the related description of the above embodiments and will not be repeated here.

[0247] After receiving the AI service related request of the UE transmitted by the second AICP layer, the second air interface protocol layer in the UE is configured to transmit the AI service related request to the base station, the first air interface protocol layer in the base station receives the AI service related request, the first air interface protocol layer transmits the AI service related request to the first AICP layer in the base station, and the first AICP layer transmits the AI service related request to the core network.

[0248] Similar to the network protocol stack arranged in the base station, in some embodiments of the present disclosure, the second AICP layer can be a protocol layer carried on the second air interface protocol layer, and the second AICP layer has the functions of transmitting AI control signaling and AI service data.

[0249] In other possible implementations, referring to FIG. 13, the second AICP layer includes a second AICP-C layer and a second AICP-U layer, the second AICP-C layer is carried on the second air interface protocol layer, and the second AICP-U layer is carried on the second air interface protocol layer.

[0250] That is, the second AICP layer can also be split into two layers: the second AICP-C layer and the second AICP-U layer, the second AICP-C layer and the second AICP-U layer have different functions, the second AICP-C layer is configured to generate AI control signaling and transmit the AI control signaling to the base station through the second air interface protocol layer, and the second AICP-U layer is configured to transmit uplink AI service data to the base station through the second air interface protocol layer.

[0251] The AI control signaling transmission process of the AICP-C layer in the UE and the base station and the AI service data transmission process of the AICP-U layer are introduced below by way of examples.

[0252] Referring to FIG. 14, FIG. 14 is a schematic diagram of a network protocol stack for transmitting AI control signaling between a UE and a base station in the case where the first air interface protocol layer and the second air interface protocol layer are current air interface protocol layers.

[0253] The second AICP-C layer generates AI control signaling, which is transmitted by the second AICP-C layer to the PDCP layer in the UE, then passes through the RLC layer in the UE and the MAC layer in the UE in sequence, reaches the PHY layer in the UE, and is sent by the PHY layer in the UE to the PHY layer in the base station. The AI control signaling then passes through the MAC layer and the RLC layer in the base station in sequence, reaches the PDCP layer in the base station, and is transmitted by the PDCP layer in the base station to the first AICP-C layer. In this way, the AI control signaling transmission process of the AICP-C layer in the UE and the base station is implemented.

[0254] It should be noted that in the case where the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the related functions of the first AICP-C layer in FIG. 14 are implemented by the first AICP layer, and the related functions of the second AICP-C layer in FIG. 14 are implemented by the second AICP layer. The embodiment shown in FIG. 14 does not constitute a limitation on the setting mode of the network protocol stack of some embodiments of the present disclosure.

[0255] Referring to FIG. 15, FIG. 15 is a schematic diagram of a network protocol stack for transmitting AI service data between a UE and a base station in the case where the first air interface protocol layer and the second air interface protocol layer are current air interface protocol layers.

[0256] For the uplink data transmission process, the second AICP-U layer transmits the uplink AI service data of the UE to the PDCP layer in the UE, then passes through the RLC layer in the UE and the MAC layer in the UE in sequence, reaches the PHY layer in the UE, and is sent by the PHY layer in the UE to the PHY layer in the base station. The uplink AI service data then passes through the MAC layer and the RLC layer in the base station in sequence, reaches the PDCP layer in the base station, and is transmitted by the PDCP layer in the base station to the first AICP-U layer. In this way, the uplink AI service data transmission process of the AICP-U layer in the UE and the base station is implemented.

[0257] For the downlink data transmission process, the first AICP-U layer receives the downlink AI service data sent by the core network, and after the first AICP-U layer transmits the downlink AI service data to the PDCP layer in the base station, the downlink AI service data passes through the RLC layer in the base station and the MAC layer in the base station in turn, and reaches the PHY layer in the base station. The PHY layer in the base station sends the downlink AI service data to the PHY layer in the UE. The downlink AI service data passes through the MAC layer and the RLC layer in the UE in turn, and reaches the PDCP layer in the UE. The PDCP layer in the UE transmits the downlink AI service data to the second AICP-U layer. In this way, the downlink AI service data transmission process of the AICP-U layer in the UE and the base station is realized.

[0258] It should be noted that, in the case that the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the related functions of the first AICP-U layer in FIG. 15 are realized by the first AICP layer, and the related functions of the second AICP-U layer in FIG. 15 are realized by the second AICP layer. The embodiments shown in FIG. 15 do not constitute a limitation on the setting mode of the network protocol stack of some embodiments of the present disclosure.

[0259] Please refer to FIG. 16, which is a schematic diagram of the network protocol stack for transmitting AI control signaling between the UE and the base station in the case that the first air interface protocol layer and the second air interface protocol layer are not the current air interface protocol layers (i.e., the first air interface protocol layer and the second air interface protocol layer are other newly designed air interface protocol layers, and the newly designed air interface protocol layers are temporarily named L1 and L2 in this embodiment, and the specific protocol stack is not limited).

[0260] The second AICP-C layer generates AI control signaling, which is transmitted by the second AICP-C layer to the newly designed air interface protocol layer in the UE. The newly designed air interface protocol layer in the UE sends the AI control signaling to the newly designed air interface protocol layer in the base station. The newly designed air interface protocol layer in the base station transmits the AI control signaling to the first AICP-C layer. In this way, the AI control signaling transmission process of the AICP-C layer in the UE and the base station is realized.

[0261] It should be noted that, in the case that the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the related functions of the first AICP-C layer in FIG. 16 are realized by the first AICP layer, and the related functions of the second AICP-C layer in FIG. 16 are realized by the second AICP layer. The embodiments shown in FIG. 16 do not constitute a limitation on the setting mode of the network protocol stack of some embodiments of the present disclosure.

[0262] Please refer to FIG. 17, which is a schematic diagram of a network protocol stack for transmitting AI service data between a UE and a base station, where the first air interface protocol layer and the second air interface protocol layer are not the current air interface protocol layers (i.e., the first air interface protocol layer and the second air interface protocol layer are other newly designed air interface protocol layers, and the newly designed air interface protocol layers are temporarily named L1 and L2 in the embodiment, and the specific protocol stack is not limited).

[0263] For the uplink data transmission process, the second AICP-U layer transmits the uplink AI service data of the UE to the newly designed air interface protocol layer in the UE, the newly designed air interface protocol layer in the UE sends the uplink AI service data to the newly designed air interface protocol layer in the base station, and the newly designed air interface protocol layer in the base station transmits the uplink AI service data to the first AICP-U layer, so that the uplink AI service data transmission process between the AICP-U layers in the UE and the base station is realized.

[0264] For the downlink data transmission process, the first AICP-U layer receives the downlink AI service data sent by the core network, after receiving the downlink AI service data sent by the core network, the first AICP-U layer transmits the downlink AI service data to the newly designed air interface protocol layer in the base station, the newly designed air interface protocol layer in the base station sends the downlink AI service data to the newly designed air interface protocol layer in the UE, and the newly designed air interface protocol layer in the UE transmits the downlink AI service data to the second AICP-U layer, so that the downlink AI service data transmission process between the AICP-U layers in the UE and the base station is realized.

[0265] It should be noted that, in the case where the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the related functions of the first AICP-U layer in FIG. 17 are realized by the first AICP layer, and the related functions of the second AICP-U layer in FIG. 17 are realized by the second AICP layer, and the embodiment shown in FIG. 17 does not constitute a limitation on the setting mode of the network protocol stack in some embodiments of the disclosure.

[0266] On the basis of the embodiment shown in FIG. 14, refer to FIG. 18, in some embodiments of the disclosure, the network protocol stack in the UE further includes a first AINAS layer (Artificial Intelligence Non-access stratum, artificial intelligence non-access layer), which is used to transmit AI signaling between the UE and the core network, and is borne on the second AICP-C layer.

[0267] The first AINAS layer is configured to generate an AI mobility request and transmit the AI mobility request to a second AICP-C layer, and the second AICP-C layer is further configured to transmit the AI mobility request to a second air interface protocol layer, and the second air interface protocol layer is further configured to transmit the AI mobility request to a base station, and the base station is configured to transmit the AI mobility request to a core network.

[0268] The second air interface protocol layer shown in FIG. 18 is an example based on the current air interface protocol stack. As shown in FIG. 18, after the first AINAS layer in the UE generates the AI mobility request, the first AINAS layer transmits the AI mobility request to the second AICP-C layer in the UE. Then, the AI mobility request passes through the PDCP layer, the RLC layer and the MAC layer of the second air interface protocol layer in sequence, and reaches the PHY layer in the UE. The PHY layer in the UE transmits the AI mobility request to the PHY layer of the first air interface protocol layer in the base station. Then, the AI mobility request passes through the MAC layer, the RLC layer and the PDCP layer of the first air interface protocol layer in sequence, and reaches the first AICP-C layer in the base station. The first AICP-C layer transmits the AI mobility request to the corresponding network function in the core network.

[0269] Exemplarily, the base station further includes a protocol stack between the base station and the core network. The protocol stack between the base station and the core network can be a point-to-point interface, a service interface or the like, which can be configured according to different application scenarios. The first AICP-C layer transmits the AI mobility request to the protocol stack included in the base station, and the protocol stack transmits the AI mobility request to the corresponding network function in the core network. The network function is, for example, a first NF (Network Function).

[0270] In some embodiments of the present disclosure, the first NF can be an AMF (Access and Mobility Management Function), and can also be other newly added or existing network functions.

[0271] Please continue to refer to FIG. 18. The network protocol stack in the first NF in the core network includes a first protocol stack and a second AINAS layer. The second AINAS layer is carried in the first protocol stack, i.e., the second AINAS layer is carried on the first protocol stack.

[0272] As described above, the first AICP-C layer transmits the AI mobility request to a protocol stack between the base station and the core network included in the base station, which transmits the AI mobility request to a first protocol stack for receiving the AI mobility request of the UE transmitted by the base station and transmitting the AI mobility request to a second AINAS layer for responding to the AI mobility request, so that the transmission process of the AI mobility request between the UE and the core network is realized.

[0273] It can be understood that, in the case that the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the related functions of the first AICP-C layer in FIG. 18 are realized by the first AICP layer, and the related functions of the second AICP-C layer in FIG. 18 are realized by the second AICP layer, and the embodiment shown in FIG. 18 does not constitute a limitation on the setting mode of the network protocol stack of some embodiments of the present disclosure.

[0274] In some embodiments, referring to FIG. 19, on the basis of the embodiment shown in FIG. 18, in the present embodiment, the first air interface protocol layer in the base station and the second air interface protocol layer in the UE are not the current air interface protocol layers, but other newly designed air interface protocol layers, as shown in FIG. 19, the newly designed air interface protocol layers in the present embodiment are temporarily named as L1 and L2, and the specific protocol stack is not limited, which can be a point-to-point interface, or a service interface, etc., and can be configured according to different application scenarios.

[0275] In FIG. 19, the transmission process of the AI mobility request between the UE and the core network can refer to the related description of the embodiment shown in FIG. 18, which will not be described here.

[0276] Similarly to the embodiment shown in FIG. 18, in the embodiment shown in FIG. 19, in the case that the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the related functions of the first AICP-C layer in FIG. 19 are realized by the first AICP layer, and the related functions of the second AICP-C layer in FIG. 19 are realized by the second AICP layer, and the embodiment shown in FIG. 19 does not constitute a limitation on the setting mode of the network protocol stack of some embodiments of the present disclosure.

[0277] In this way, by introducing the AINAS layer, i.e., the artificial intelligence non-access layer, between the UE and the core network, the AI mobility request between the UE and the core network can be transmitted.

[0278] In some embodiments, based on the embodiment shown in FIG. 15, referring to FIG. 20, in some embodiments of the present disclosure, the network protocol stack in the UE further includes a first AI layer, the first AI layer (AI Layer) is used to transmit AI service data between the UE and the core network, and the first AI layer is carried on the second AICP-U layer.

[0279] In the process of uplink data transmission, the first AI layer is used to generate uplink AI service data of the UE, and transmit the uplink AI service data to the second AICP-U layer, the second AICP-U layer transmits the uplink AI service data to the second air interface protocol layer, and the second air interface protocol layer transmits the uplink AI service data to the base station, so as to transmit the uplink AI service data to the core network through the base station.

[0280] The second air interface protocol layer shown in FIG. 20 is an example based on the current air interface protocol stack. As shown in FIG. 20, after the first AI layer in the UE generates uplink AI service data, the first AI layer transmits the uplink AI service data to the second AICP-U layer in the UE, and then the uplink AI service data passes through the PDCP layer, the RLC layer and the MAC layer included in the second air interface protocol layer in sequence, and reaches the PHY layer in the UE. The PHY layer in the UE sends the uplink AI service data to the PHY layer included in the first air interface protocol layer in the base station, and then the uplink AI service data passes through the MAC layer, the RLC layer and the PDCP layer included in the first air interface protocol layer in sequence, and reaches the first AICP-U layer in the base station. The first AICP-U layer transmits the uplink AI service data to the corresponding network function in the core network.

[0281] Exemplarily, the base station further includes a protocol stack between the base station and the core network, the protocol stack between the base station and the core network can be a point-to-point interface, or a service interface, etc., which can be configured according to different application scenarios. The first AICP-U layer transmits the uplink AI service data to the protocol stack included in the base station, and the protocol stack transmits the uplink AI service data to the corresponding network function in the core network, for example, the fourth NF.

[0282] In some embodiments of the present disclosure, the fourth NF can be a UPF (User Plane Function), and of course can be other newly added network functions.

[0283] Please continue to refer to FIG. 20, the network protocol stack in the fourth NF set in the core network includes a second protocol stack and a second AI layer, the second AI layer is carried on the protocol stack included in the fourth NF between the base station and the core network, which is referred to as the second protocol stack, that is, the second AI layer is carried on the second protocol stack.

[0284] As described above, the first AICP-U layer transmits the uplink AI service data to the protocol stack between the base station and the core network included in the base station, and the protocol stack transmits the uplink AI service data to a second protocol stack, which is configured to receive the uplink AI service data transmitted by the base station and transmit the uplink AI service data to a second AI layer, which is configured to respond to the uplink AI service data. In this way, the transmission process of the uplink AI service data is realized.

[0285] The process of uplink data transmission in the embodiment shown in FIG. 20 is described above. For the process of downlink data transmission, the second AI layer in the fourth NF is further configured to generate downlink AI service data of the UE and transmit the downlink AI service data to the second protocol stack, which is further configured to transmit the downlink AI service data to the base station to transmit the downlink AI service data to the UE through the base station.

[0286] As described above, the base station further includes a protocol stack between the base station and the core network, which can be a point-to-point interface, a service interface, or the like, and can be configured according to different application scenarios. The second protocol stack transmits the downlink AI service data to the protocol stack between the base station and the core network included in the base station, and the protocol stack transmits the downlink AI service data to the first AICP-U layer, which transmits the downlink AI service data to the first air interface protocol layer, and the first air interface protocol layer transmits the downlink AI service data to the second air interface protocol layer in the UE.

[0287] In this way, the second air interface protocol layer receives the downlink AI service data transmitted by the base station and transmits the downlink AI service data to the second AICP-U layer, which is further configured to transmit the downlink AI service data to the first AI layer, which is further configured to respond to the downlink AI service data. In this way, the transmission process of the downlink AI service data is realized.

[0288] In some embodiments, referring to FIG. 21, based on the embodiment shown in FIG. 20, in the present embodiment, the first air interface protocol layer in the base station and the second air interface protocol layer in the UE are not the current air interface protocol layer, but other newly designed air interface protocol layers. As shown in FIG. 21, the newly designed air interface protocol layers are temporarily named L1 and L2, and the specific protocol stack is not limited, which can be a point-to-point interface, a service interface, or the like, and can be configured according to different application scenarios.

[0289] In FIG. 21, the transmission processes of the uplink AI service data and the downlink AI service data can be referred to the related description of the embodiment shown in FIG. 20, which will not be described here.

[0290] It can be understood that, in the case that the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the related functions of the first AICP-U layer in FIG. 20 and FIG. 21 are implemented by the first AICP layer, and the related functions of the second AICP-U layer in FIG. 20 and FIG. 21 are implemented by the second AICP layer, and the embodiments shown in FIG. 20 and FIG. 21 do not constitute a limitation on the setting mode of the network protocol stack of some embodiments of the present disclosure.

[0291] In this way, by introducing an AI layer (AI Layer), that is, an artificial intelligence layer, between the UE and the core network, the AI service data between the UE and the core network can be transmitted.

[0293] In the following, a data transmission method implemented based on the network protocol stack of the above-mentioned embodiments is introduced.

[0294] In some embodiments, as shown in FIG. 22, a data transmission method is provided, which is used in a base station, the base station is provided with the network protocol stack mentioned in any of the above-mentioned embodiments and arranged in the base station, the network protocol stack includes a first air interface protocol layer and a first AICP layer, and the method includes the following steps:

[0295] In step 2201, the first air interface protocol layer receives an AI request sent by the UE, and transmits the AI request to the first AICP layer, the AI request including an AI service related request and / or an AI mobility request.

[0296] The UE is provided with the network protocol stack mentioned in any of the above-mentioned embodiments and arranged in the UE, the network protocol stack includes a second air interface protocol layer and a second AICP layer, the second AICP layer in the UE transmits an AI request of the UE to the second air interface protocol layer in the UE, and the second air interface protocol layer sends the AI request to the first air interface protocol layer in the base station, so that the first air interface protocol layer in the base station receives the AI request sent by the UE, and transmits the AI request to the first AICP layer in the base station.

[0297] In step 2202, the first AICP layer transmits the AI request to the core network.

[0298] In some embodiments of the present disclosure, the AI request includes an AI service-related request and / or an AI mobility request. In the following, the implementation process of step 2202 is introduced by taking the AI request including the AI mobility request and the AI service-related request as examples respectively.

[0299] Firstly, the AI request including the AI mobility request is taken as an example for description.

[0300] The network protocol stack in the UE further includes a first AINAS layer. The first AINAS layer generates the AI mobility request and transmits the AI mobility request to a second AICP-C layer in the UE. The second AICP-C layer transmits the AI mobility request to a second air interface protocol layer, i.e., the AI mobility request is transmitted to the second air interface protocol layer through the second AICP-C layer in the UE, and then the AI mobility request is sent to the base station by the second air interface protocol layer in the UE.

[0301] After the first air interface protocol layer in the base station receives the AI mobility request sent by the UE, the AI mobility request is transmitted to the first AICP layer.

[0302] As described above, in some embodiments of the present disclosure, the first AICP layer can include a first AICP-C layer. After receiving the AI mobility request transmitted by the first air interface protocol layer, the first AICP-C layer analyzes the request type of the AI mobility request and determines the first NF according to the request type. The first AICP-C layer sends the AI mobility request to the first NF to implement the process of step 2202.

[0303] In some embodiments of the present disclosure, the AI mobility request includes a mobility establishment request, a mobility modification request, or a mobility release request (if the UE is initial access, there is no mobility modification request and mobility release request).

[0304] In the following, the process that the first AICP-C layer analyzes the request type of the AI mobility request and determines the first NF according to the request type is introduced.

[0305] In the case where the request type of the AI mobility request is the mobility establishment request, in some embodiments, the base station local configuration information can store a corresponding relationship between the service type and the identifier of the corresponding first NF. The corresponding relationship represents the service types supported by each first NF. The first AICP-C layer finds the identifier of the first NF associated with the service type according to the service type corresponding to the mobility establishment request in the local configuration information.

[0306] In some embodiments, the first AICP-C layer determines a service type corresponding to the mobility establishment request, and obtains an identifier of the first NF associated with the service type from a second NF, which can be a NRF (Network Repository Function) for example.

[0307] In a case where the request type of the AI mobility request is a mobility modification request or a mobility release request, the first NF is a NF currently serving the UE or a NF that has served the UE.

[0308] After determining the first NF, the first AICP-C layer sends the AI mobility request to the first NF.

[0309] The first NF is provided with the network protocol stack mentioned in any of the above embodiments, which includes a first protocol stack and a second AINAS layer. After receiving the AI mobility request sent by the base station, the first protocol stack transmits the AI mobility request to the second AINAS layer, and the second AINAS layer responds to the AI mobility request.

[0310] For example, the second AINAS layer generates an AI mobility response to the AI mobility request, which includes relevant AI mobility information such as success, failure, cancellation, etc. of handover. The second AINAS layer transmits the AI mobility response to the first protocol stack, and the first protocol stack sends the AI mobility response to the base station to realize the process of the second AINAS layer responding to the AI mobility request.

[0311] After the first AICP-C layer in the base station receives the AI mobility response of the first NF to the AI mobility request (specifically through the protocol stack between the base station and the core network provided in the base station to receive the AI mobility response sent by the first NF), the first AICP-C layer transmits the AI mobility response to the first air interface protocol layer. The first air interface protocol layer sends the AI mobility response to the UE, the second air interface protocol layer in the UE receives the service response to the AI service-related request sent by the base station, and transmits the service response to the second AICP-C layer in the UE. The second AICP-C layer transmits the service response to the AI service-related request to the first AINAS layer in the UE.

[0312] In this way, the transmission and response process of the AI mobility request between the UE and the first NF is realized.

[0313] The above embodiments take the AI request including the AI mobility request as an example to introduce the implementation process of step 2202. The following takes the AI request including the AI service-related request as an example to introduce the implementation process of step 2202.

[0314] In a case that the AI request comprises an AI service related request, the AI service related request comprises AI control signaling, and the AI control signaling comprises a service establishment request, a service modification request, or a service release request (if the UE is initial access, there is no service modification request and service release request).

[0315] The second AICP-C layer in the UE generates the AI control signaling, and transmits the AI control signaling to the second air interface protocol layer, the second air interface protocol layer transmits the AI control signaling to the first air interface protocol layer in the base station, and the first air interface protocol layer transmits the AI control signaling to the first AICP-C layer in the base station.

[0316] The first AICP-C layer analyzes the request type of the AI service related request, and determines the third NF according to the request type, and sends the AI service related request to the third NF, which can be, for example, an SMF (Session Management Function), to implement the process of step 2022.

[0317] In the following, the process in which the first AICP-C layer analyzes the request type of the AI service related request and determines the third NF according to the request type is introduced.

[0318] In a case that the AI service related request comprises a service establishment request, in some embodiments, the base station can store a correspondence between service types and identifiers of the third NFs in local configuration information, and the first AICP-C layer can find the identifier of the third NF associated with the service type of the AI service related request in the local configuration information according to the service type corresponding to the AI service related request.

[0319] In some embodiments, the first AICP-C layer can obtain the identifier of the third NF associated with the service type of the AI service related request from the second NF according to the service type corresponding to the AI service related request.

[0320] In a case that the AI service related request comprises a service modification request or a service release request, the third NF is a NF currently serving the UE or a NF that has historically served the UE.

[0321] After the first AICP-C layer determines the third NF, the first AICP-C layer sends the AI service related request to the third NF, and as described above, the AI service related request comprises a service establishment request, a service modification request, or a service release request.

[0322] After the third NF receives the AI service related request sent by the base station, the third NF determines a fourth NF corresponding to the AI service related request according to the AI service related request.

[0323] In some embodiments, in the case that the AI service related request comprises a service establishment request, the fourth NF is determined by the third NF according to the AI service related request; in the case that the AI service related request comprises a service modification request or a service release request, the fourth NF is the NF currently serving the UE or the NF that has served the UE.

[0324] After the third NF determines the corresponding fourth NF, the third NF sends the AI service related request to the fourth NF. If the AI service related request comprises a service establishment request, the service establishment request is used to request the fourth NF (such as a UPF) to allocate user plane related resources, AI QoS (Quality of Service), ID (Identity Document), etc. If the AI service related request comprises a service modification request or a service release request, the fourth NF is requested to modify or release the originally allocated user plane related resources and ID.

[0325] The fourth NF responds to the AI service related request and sends a service response to the third NF, wherein if the fourth NF receives a service establishment request, the service response comprises the user plane related resources, AI QoS, ID, etc. allocated by the fourth NF; if the AI service related request comprises a service modification request or a service release request, the fourth NF modifies / releases the originally allocated user plane related resources, AI QoS, ID, etc. and returns the corresponding service response to the third NF.

[0326] After the third NF receives the service response to the AI service related request sent by the fourth NF, the third NF sends the service response to the AI service related request to the base station.

[0327] After the first AICP-C layer in the base station receives the service response sent by the third NF to the AI service related request, the first AICP-C layer transmits the service response to the first air interface protocol layer, the first air interface protocol layer sends the service response to the second air interface protocol layer in the UE, and the second air interface protocol layer transmits the service response to the second AICP-C layer in the UE.

[0328] It should be noted that in the case that the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the method steps performed by the first AICP-C layer in the above method are performed by the first AICP layer, and the method steps performed by the second AICP-C layer in the above method are performed by the second AICP layer.

[0329] The implementation process of step 2202 is introduced above in the case that the AI request includes the AI service related request, and the AI service related request includes the AI control signaling. After the UE receives the user plane related resources, the AI QoS, the ID, and the like allocated by the fourth NF, or after the UE receives the user plane related resources, the AI QoS, the ID, and the like modified by the fourth NF, the UE can perform the transmission of the uplink AI service data (it can be understood that if the UE receives a service response for a service release request, the uplink data transmission process will not be performed).

[0330] As described above, the first AICP layer in the base station further includes a first AICP-U layer, and the AI service related request further includes the uplink AI service data. Therefore, the first AICP-U layer can further transmit the uplink AI service data to the core network.

[0331] In some embodiments of the present disclosure, the network protocol stack in the UE further includes a first AI layer, the first AI layer generates the uplink AI service data of the UE, the second AICP layer in the UE includes a second AICP-C layer and a second AICP-U layer, the first AI layer transmits the uplink AI service data to the second AICP-U layer in the UE, and the second AICP-U layer transmits the uplink AI service data to the second air interface protocol layer in the UE.

[0332] The second air interface protocol layer in the UE transmits the uplink AI service data to the first air interface protocol layer in the base station, the first air interface protocol layer transmits the uplink AI service data to the first AICP-U layer in the base station, and then the first AICP-U layer transmits the uplink AI service data to the core network (for example, to the fourth NF).

[0333] The fourth NF is provided with the network protocol stack in the fourth NF mentioned in any of the above embodiments, the network protocol stack includes a second protocol stack and a second AI layer, the second protocol stack in the fourth NF receives the uplink AI service data of the UE transmitted by the base station, and transmits the uplink AI service data to the second AI layer, and the second AI layer responds to the uplink AI service data.

[0334] In this way, the transmission and response process of the uplink AI service data is realized.

[0335] It should be noted that in some embodiments of the present disclosure, the UE can encapsulate the AI mobility request and the AI service related request in the same request message and send them in parallel, or the UE can send the AI mobility request and the AI service related request separately in series, and the sending manner of the AI related request is not limited here.

[0336] The UE receives the user plane related resources, AI QoS, ID, etc. allocated by the fourth NF, or after the UE receives the user plane related resources, AI QoS, ID, etc. modified by the fourth NF, the UE can perform the transmission process of the uplink AI service data. In some embodiments of the present disclosure, in order to realize the transmission of the downlink AI service data, in the case that the service response includes a service establishment response or a service modification response, the first AI CP-U layer sends an AI service update request to the third NF (it can be understood that if the base station receives a service response for a service release request, this step will not be performed).

[0337] The AI service update request carries the resource identifier of the user plane resource corresponding to the AI service related request of the base station, and the resource identifier indicates the user plane related resources, AI QoS, ID, etc. allocated by the base station for the AI service related request.

[0338] After the third NF receives the AI service update request sent by the base station, the third NF sends the AI service update request to the fourth NF, so that the fourth NF learns the related resources allocated by the base station for the AI service related request, and can determine the sending resource information of the downlink AI service data. The fourth NF sends an AI service update response to the third NF in response to the AI service update request, the third NF receives the AI service update response sent by the fourth NF in response to the AI service update request, and the third NF sends the AI service update response to the base station. The first AI CP-U layer in the base station receives the AI service update response sent by the third NF in response to the AI service update request.

[0339] After the sending channel of the downlink AI service data is established, the second AI layer in the fourth NF (such as the UPF) generates the downlink AI service data of the UE, and transmits the downlink AI service data to the second protocol stack in the fourth NF. The second protocol stack transmits the downlink AI service data to the base station to transmit the downlink AI service data to the UE through the base station.

[0340] After the first AI CP-U layer in the base station receives the downlink AI service data sent by the core network, the first AI CP-U layer transmits the downlink AI service data to the first air interface protocol layer in the base station, and the first air interface protocol layer in the base station transmits the downlink AI service data to the UE.

[0341] The second air interface protocol layer in the UE receives the downlink AI service data sent by the base station, and transmits the downlink AI service data to the second AI CP-U layer in the UE. The second AI CP-U layer transmits the downlink AI service data to the first AI layer in the UE, and the first AI layer responds to the downlink AI service data. In this way, the transmission and response process of the uplink AI service data is realized.

[0342] It should be noted that, in the case that the first AICP layer is not split into the first AICP-C layer and the first AICP-U layer, and the second AICP layer is not split into the second AICP-C layer and the second AICP-U layer, the method steps performed by the first AICP-U layer in the above method are performed by the first AICP layer, and the method steps performed by the second AICP-U layer in the above method are performed by the second AICP layer.

[0397] The second AICP-C layer in the UE generates AI control signaling, and transmits the AI control signaling to the second air interface protocol layer; the first AINAS layer in the UE generates an AI mobility request, and transmits the AI mobility request to the second air interface protocol layer through the second AICP-C layer.

[0398] The second air interface protocol layer in the UE sends the AI service related request and / or the AI mobility request to the base station.

[0399] The AI service related request and the AI mobility request can be sent in parallel, i.e., encapsulated in the same request message, or can be sent in series, i.e., the AI service related request and the AI mobility request are sent respectively.

[0400] Step 2702, the base station receives the AI request sent by the UE, and the base station selects the AMF and / or the SMF.

[0401] The first air interface protocol layer in the base station receives the AI request sent by the UE, and transmits the AI request to the first AICP layer.

[0402] Selection of AMF (the AI mobility request includes a mobility setup request, a mobility modification request, or a mobility release request):

[0403] The selection of the AMF is performed by the first AICP-C layer in the base station, and in the case that the AI mobility request includes a mobility setup request, the first AICP-C layer in the base station finds the identity of the AMF in the local configuration information according to the service type corresponding to the mobility setup request, or the first AICP-C layer acquires the identity of the AMF from the NRF according to the service type corresponding to the mobility setup request.

[0404] In the case that the AI mobility request includes a mobility modification request or a mobility release request, the AMF is an NF that is currently serving the UE or an NF that has historically served the UE.

[0405] Selection of SMF (the AI service-related request includes AI control signaling, and the AI control signaling includes a service setup request, a service modification request, or a service release request):

[0406] The selection of the SMF is performed by the first AICP-C layer in the base station, and in the case that the AI service-related request includes a service setup request, the first AICP-C layer in the base station finds the identity of the SMF in the local configuration information according to the service type corresponding to the AI service-related request, or the first AICP-C layer acquires the identity of the SMF from the NRF according to the service type corresponding to the AI service-related request.

[0407] In the case that the AI service-related request includes a service modification request or a service release request, the SMF is an NF that is currently serving the UE or an NF that has historically served the UE.

[0408] Step 2703, the base station sends an AI mobility request to the AMF.

[0409] The AI mobility request is sent by the first AICP-C layer in the base station to the AMF through the protocol stack between the base station and the core network in the base station.

[0410] Step 2704, the base station sends an AI service-related request to the SMF.

[0411] The AI service-related request is sent by the first AICP-C layer in the base station to the SMF.

[0412] Step 2705, the SMF receives the AI service-related request sent by the base station, and the SMF performs the selection of the UPF (AI).

[0413] As described above, the AI service related request includes AI control signaling, and the AI control signaling includes a service establishment request, a service modification request, or a service release request.

[0414] In a case where the AI service related request includes the service establishment request, the UPF(AI) is determined by the SMF according to the AI service related request; in a case where the AI service related request includes the service modification request or the service release request, the UPF(AI) is an NF currently serving the UE or an NF that has served the UE.

[0415] At step 2706, the SMF sends the AI service related request to the UPF(AI).

[0416] At step 2707, the SMF receives a service response to the AI service related request sent by the UPF(AI).

[0417] At step 2708, the SMF sends the service response to the AI service related request to the base station.

[0418] The first AICP-C layer in the base station receives the service response sent by the SMF to the AI service related request, and transmits the service response to the first air interface protocol layer.

[0419] At step 2709, the AMF sends an AI mobility response to the AI mobility request to the base station.

[0420] The first protocol stack in the AMF sends the AI mobility response to the base station, and the first AICP-C layer in the base station receives the AI mobility response to the AI mobility request by the first NF, and transmits the AI mobility response to the first air interface protocol layer.

[0421] At step 2710, the base station sends the AI mobility response and the service response to the UE.

[0422] Next, the UE can then transmit uplink AI service data, and the AI service related request further includes the uplink AI service data, the first AI layer in the UE generates the uplink AI service data, and transmits the uplink AI service data to the second AICP-U layer, the second AICP-U layer in the UE transmits the uplink AI service data to the second air interface protocol layer, the first air interface protocol layer in the base station receives the uplink AI service data, and transmits the uplink AI service data to the first AICP-U layer, and the first AICP-U layer in the base station transmits the uplink AI service data to the UPF(AI).

[0423] The second protocol stack in the UPF(AI) receives the uplink AI service data of the UE transmitted by the base station, and transmits the uplink AI service data to the second AI layer, and the second AI layer in the UPF(AI) responds to the uplink AI service data.

[0424] In order to be able to transmit downlink AI service data, next:

[0425] Step 2711, in the case that the service response includes a service establishment response or a service modification response, the base station sends an AI service update request to the SMF.

[0426] The first AICP-U layer in the base station sends an AI service update request to the SMF, and the AI service update request carries the resource identifier of the user plane resource corresponding to the AI service related request of the base station.

[0427] Step 2712, the SMF receives the AI service update request sent by the base station, and the SMF sends the AI service update request to the UPF(AI).

[0428] Step 2713, the SMF receives the AI service update response sent by the UPF(AI) for the AI service update request.

[0429] Step 2714, the SMF sends the AI service update response to the base station.

[0430] The first AICP-U layer in the base station receives the AI service update response sent by the SMF for the AI service update request, so that the UPF(AI) can determine the transmission resource and other information of the downlink AI service data at the base station side, thereby enabling the transmission of the downlink AI service data.

[0431] The second AI layer in the UPF(AI) generates downlink AI service data of the UE, and transmits the downlink AI service data to the second protocol stack, and the second protocol stack in the UPF(AI) transmits the downlink AI service data to the base station. The first AICP-U layer in the base station receives the downlink AI service data sent by the core network, and transmits the downlink AI service data to the first air interface protocol layer; the first air interface protocol layer in the base station transmits the downlink AI service data to the UE. The second air interface protocol layer in the UE receives the downlink AI service data sent by the base station, and transmits the downlink AI service data to the second AICP-U layer; the second AICP-U layer in the UE transmits the downlink AI service data to the first AI layer; the first AI layer in the UE responds to the downlink AI service data.

[0432] Among them, step 2703 and step 2704 can be performed in parallel, or can be performed in series, when performed in series, step 2703 and step 2704 do not limit the order; step 2708 and step 2709 can be performed in parallel, or can be performed in series, when performed in series, step 2708 and step 2709 do not limit the order.
