Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an information transmission method, apparatus, and storage medium. Background Art

[0002] In the integrated communication and sensing network scenario, there are obvious adaptability problems with the cubic grid-based spatial information currently provided by the Sensing Function (SF) to the Application Function (AF). This discrete data representation method not only makes it difficult to accurately reflect the continuous sensing characteristics in the actual environment, but also lacks the association with the key parameters of the base station, resulting in the AF's inability to establish an accurate understanding of the environmental situation. This information gap severely restricts the decision-making ability of the AF in communication and sensing collaboration, making it difficult to achieve dynamic resource allocation for sensing-assisted communication and unable to support the collaborative optimization of communication-enabled sensing, ultimately affecting the overall communication and sensing integration efficiency of the network. Summary of the Invention

[0003] Based on the above technical problems, this application provides an information transmission method, apparatus, and storage medium, which are beneficial to improving the AF's sensing ability. The technical solutions of this application are as follows:

[0004] In a first aspect, this application provides an information transmission method, which is applied to the AF. The method includes:

[0005] Sending a first request message to the sensing network element SF. The first request message is used to request the base station information in the SF, and the first request message includes information indicating the permission level of the AF; receiving a first response message sent by the SF. The first response message includes some or all of the base station information in the SF, and the first response message is determined based on the permission level of the AF.

[0007] In a possible implementation, the base station information includes a first type of information and a second type of information; the first type of information is used to indicate the dynamic attributes of the base station.

Those skilled in the art can understand that the terms such as "first" and "second" do not limit the quantity and execution order.

[0051] Communication and sensing integration (integrated communication and sensing) is a representative technology in the enhanced version of the fifth-generation mobile communication technology (5th Generation Advanced, 5G-A) stage and is also included in the main scenarios of the sixth-generation mobile communication technology (6th Generation, 6G) released by the International Telecommunication Union (ITU). It has broad prospects in fields such as low-altitude UAV supervision, water area supervision, railway supervision, and disaster warning. With the help of communication and sensing integration technology, one network can be used for two purposes, improving quality and efficiency.

[0052] The synesthesia integration technology involves three main network elements: SF, AF, and the radio access network element (Radio Access Network, RAN).

[0053] SF: It can be an independent network element or co-located with other network elements. The deployment method can be centralized or distributed. Its functions include the selection of sensing devices, the control of sensing services, independently or jointly with other network elements to process sensing measurement data, and output the sensing results to the sensing requester.

[0054] AF: Provides sensing service requirements to SF through core network functions. In the control plane transmission protocol stack of the interface, AF acts as the server side of the Transmission Control Protocol (TCP), while SF acts as the TCP client.

[0055] RAN: Supports the sensing function. Collects sensing measurement data and returns this data to SF.

[0056] Exemplarily, Figure 1 provides a schematic diagram of the structure of the control plane protocol stack of the SF-AF interface. The control plane (denoted as SF-AF CP) transmission protocol stack of the SF-AF interface uses TCP / Internet Protocol (IP) / Media Access Control (MAC) / Ethernet (ETH).

[0057] AF acts as the TCP server, and SF acts as the TCP client.

[0058] The control plane messages between SF and AF include the following:

[0059] 1. After the establishment of the transmission link between SF and AF is completed each time, SF sends a registration request message (RegisterReq) to AF, and AF replies with a registration response message (RegisterResp).

[0060] Among them, the relevant information of the fields included in the registration request message is shown in Table 1. The relevant information of the fields included in the registration response message is shown in Table 2.

[0103]

[0104] 4. The AF issues a StopSenseTaskReq message to stop the sensing detection task according to the requirements. The SF replies with a StopSenseTaskResp message.

[0105] 5. When the AF loses the reported sensing capabilities due to certain reasons, it can request the SF to re-report all sensing capability information through the SenseCapabilitySynReq message. After the SF completes the synchronization, it will reply with the SenseCapabilitySynComplete message.

[0106] In the integrated communication and sensing network scenario, there are obvious compatibility issues with the cuboid rasterized space information provided by the current SF to the AF. This discrete data representation method not only makes it difficult to accurately reflect the continuous sensing characteristics in the actual environment, but also lacks the association with the key parameters of the base station, resulting in the AF being unable to establish an accurate understanding of the environmental situation. Currently, a large amount of base station information is included in the SF to assist the AF in sensing, but the SF cannot determine whether to provide base station information to the AF and which base station information to provide.

[0107] In view of this, the present application provides an information transmission method. The AF sends a first request message to the sensing network element SF. The first request message is used to request the base station information in the SF, and the first request message includes information indicating the permission level of the AF. The AF receives the first response message sent by the SF. The first response message includes some or all of the base station information in the SF, and the first response message is determined based on the permission level of the AF. In this way, the SF can provide appropriate base station information to the AF based on the permission level of the AF, improving the sensing ability of the AF so that the AF can achieve more accurate sensing result presentation and management operations.

[0108] The information transmission method provided by the embodiments of the present application can be applied to systems with various communication systems. For example, the systems to which the information transmission method provided by the embodiments of the present application can be applied include but are not limited to the new radio system, the long term evolution (LTE) system, various versions evolved from LTE, the 5th generation (5G) communication system, the wireless fidelity (Wi-Fi) system, the communication systems related to the third generation partnership project (3GPP), the ambient internet of things (AmbientIoT) system, or systems integrating multiple systems. In addition, the information transmission method provided by the embodiments of the present application can also be applied to future-oriented communication systems (such as 6G, 7G communication systems), etc. The embodiments of the present application do not limit this.

[0141] Among them, the service display type AF has the lowest permission and can only complete perception task management, such as basic operations like registration, task start / stop, etc., and cannot obtain base station information.
