Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to an information transmission method and device and storage medium. BACKGROUND

[0002] In the sense of integration network scene, the cubic gridding space information provided by the current sensing function network element (Sensing Function, SF) to the application function network element (Application Function, AF) has obvious adaptability problems. This discrete data expression method not only cannot accurately reflect the continuous sensing characteristics in the actual environment, but also lacks association with the key parameters of the base station, which causes the AF to be unable to establish accurate environmental situation understanding. This information loss seriously restricts the decision-making ability of the AF in the sense of coordination, which not only makes it difficult to realize the dynamic allocation of resources for sensing-assisted communication, but also cannot support the collaborative optimization of communication-enabled sensing, ultimately affecting the overall sense of integration efficiency of the network.

Any embodiment or design scheme described as “exemplarily” or “for example” in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words such as “exemplarily” or “for example” are intended to present the relevant concept in a specific manner.

[0050] In order to clearly describe the technical solutions in the embodiments of the present application, in the embodiments of the present application, the words “first”, “second” and the like are used to distinguish the same or similar items with basically the same function and role, and those skilled in the art can understand that the words “first”, “second” and the like are not used to limit the quantity and execution order.

[0051] Communication and perception integration (communication and perception integration) is a representative technology in the 5th Generation Advanced (5G-A) stage, and is also included in the main scenarios of the 6th Generation (6G) mobile communication technology released by the International Telecommunication Union (ITU). It has broad prospects in the fields of low-altitude unmanned aerial vehicle supervision, water area supervision, railway supervision, disaster warning and the like. With the help of communication and perception integration technology, one network can be used for two purposes, and the quality and efficiency can be improved.

[0052] The integrated sensing technology involves three main network elements: SF, AF, and Radio Access Network (RAN).

[0053] SF: Can be an independent network element or co-located with other network elements. Deployment can be centralized or distributed. Functions include selecting sensing devices, controlling sensing services, processing sensing measurement data independently or jointly with other network elements, and outputting sensing results to the sensing requester.

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

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

[0056] For example, Figure 1 The diagram provides a schematic of the control plane protocol stack for the SF and AF interfaces. The control plane (denoted as SF-AF CP) transport protocol stack for the SF and AF interfaces 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] Control plane messages between SF and AF include the following:

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

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

[0104] 4. AF sends a Stop Sense Task Request message (StopSenseTaskReq) to stop the sensing task according to the requirement. SF replies a Stop Sense Task Response message (StopSenseTaskResp).

[0105] 5、When the AF loses the reported sensing capability for some reason, it can request the SF to re-report all sensing capability information through a sense capability synchronization request message (SenseCapabilitySynReq), and the SF replies with a sense capability synchronization complete message (SenseCapabilitySynComplete) after synchronization is completed.

At present, the SF contains a large amount of base station information that can help the AF to perceive, but the SF cannot determine whether to provide the base station information to the AF and which base station information to provide.

[0107] In view of this, the application provides an information transmission method, the AF sends first request information to the sensing network element SF, the first request information is used to request to obtain the base station information in the SF, and the first request information includes information used to indicate the permission level of the AF; the AF receives the first response information sent by the SF, the first response information includes part or all of the base station information in the SF, and the first response information 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, improve the sensing capability of the AF, so as to realize more accurate sensing result presentation and management operation of the AF.
