The following will be described first:

(1) Combination of artificial intelligence (Artificial Intelligence, AI) with a communication network;

FIG. 2 is a flow chart of AI-based communication network optimization provided by the related art, as shown in FIG. 2, the model training function and the model reasoning function are key functions in the overall flow of AI-based communication network optimization;

the model training function generates an AI model based on training data, and deploys the model to the model reasoning function after the model validity test is completed. In the process of generating the AI model, the model training function needs to acquire and analyze a large amount of data, has high requirements on hardware performance and calculation power, and is mainly deployed on network side equipment, such as operation and maintenance management nodes (Operation Administration and Maintenance, OAM) and base stations.

The model reasoning function takes reasoning data as input based on the model to obtain AI reasoning output, such as air interface index prediction. The model reasoning function requires less hardware performance and computational effort than the model training function. With the continuous improvement of the terminal capability and even the addition of an AI special chip neural network processor (Neural Processing Unit, NPU), the AI driving efficiency is also continuously improved, so that model reasoning and even partial model training are possible at the terminal side.

(2) Protocol stacks of control plane and user plane;

in a mobile communication system, data to be transmitted at least includes user data and control signaling, where transmission characteristics of the user data and the control signaling are obviously different, for example, the user data may have a large data size, the control signaling has a relatively smaller data size, delay and reliability required by the control signaling are high, the control signaling is visible to and terminates in the network, processing is required by the network, and the user data content is transparent to the network.

Based on the different features described above, the concepts of a control plane (control plane) and a user plane (user plane) were introduced. The user plane functions are mainly used for supporting user data transmission, and the control plane functions are mainly used for supporting control signaling transmission, such as RRC connection establishment, bearer establishment, radio resource configuration, etc. On the radio air interface, data for the user plane is sent over data radio bearers (Data Radio Bearer, DRB) and data for the control plane is sent over signaling radio bearers (Signalling Radio Bearer, SRB).

In a communication system, a user plane protocol stack is composed of a service data adaptation protocol (Service Data Adaptation Protocol, SDAP), a packet data convergence protocol (Packet Data Convergence Protocol, PDCP), a radio link Layer control protocol (Radio Link Control, RLC), a medium Access control protocol (Medium Access Control, MAC) and a Physical Layer (PHY) Layer, fig. 3 is a schematic diagram of a user plane protocol stack provided by the related art, fig. 4 is a schematic diagram of a control plane protocol stack provided by the related art, and as shown in fig. 3 and 4, the control plane protocol stack is composed of a Non-Access Layer (NAS), a radio resource control (Radio Resource Control, RRC), PDCP, RLC, MAC and a PHY Layer, RRC messages between a terminal and a base station are encapsulated in PDCP service data units (Service Data Unit, SDU), and a single PDCP SDU maximally supports 9000 bytes. To meet the transmission of larger RRC messages, 5G supports RRC message segmentation, with a maximum of 5 segments for the downlink and 16 segments for the uplink.

If the model training function is deployed on a base station and the model reasoning function is deployed on a terminal, the AI model needs to interact between the network and the terminal. Only 5 segments are supported in the current downlink, i.e. the maximum downlink RRC message is 45000 bytes. However, if the existing RRC messaging is still used, a large number of segments, such as the 9M-sized AI model, would be required, and the segments would need to be tapped to approximately 1000 segments. The large number of RRC segments may affect the transmission of other control signaling and affect the real-time performance of the network control.

Therefore, the embodiment of the application provides an information transmission method, device and equipment.
