Description

Transmission method, device, related equipment and readable storage medium of perception data

Technical Field

Background Art

The sensing function (SF) network element responsible for sensing service processing can perform sensing service analysis and provide sensing results based on the received sensing requirements. Its deployment form can be independent deployment or co-deployed with 5G core network (5G Core Network, 5GC) network elements (such as access and mobility management function (Access and Mobility Management Function, AMF) or local management function (Location Management Function, LMF), etc.). According to the deployment requirements, SF can exist in two forms: sensing function-control plane (Sensing Function-Control Plane, SF-C) and sensing function-user plane (Sensing Function-User Plane, SF-U).

The transmission method of perception data depends on the perception service requester. Currently, perception service requests are usually executed by user equipment (UE).

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The embodiment of the present invention provides a method for transmitting perception data, which can be applied to realize the transmission of perception data when an external AF requests a perception service. Please refer to Figure 1, which is one of the flow diagrams of the method for transmitting perception data provided by the embodiment of the present invention. The method is applied to an access side device and executed by the access side device. As shown in Figure 1, the method specifically includes the following steps:

Step 101: receive a first perception service request, where the first perception service request is used to request the access side device to perform a perception service, and the first perception service request is triggered based on a second perception service request. Both the first perception service request and the second perception service request carry an application identifier, and the application identifier is used to identify the AF network element that sends the second perception service request.

The access side device receives a first perception service request carrying an application identifier, wherein the first perception service request may be sent by an SF-C network element or by an access and mobility management function (AMF) network element. Different implementation methods may be adopted according to different actual conditions.

Optionally, step 101 includes:

receiving the first perception service request sent by the SF-C network element, or,

Receive the first perception service request forwarded by the SF-C network element through the AMF network element.

As an optional implementation, the SF-C network element receives the second perception service request sent by the AF network element, and the second perception service request carries an application identifier. The SF-C network element sends the first perception service request to the access side device. The access side device receives the first perception service request sent by the SF-C network element.

As another optional implementation, the SF-C network element receives a second perception service request sent by the AF network element, and the second perception service request carries an application identifier. The SF-C network element sends a first perception service request to the AMF network element to request the AMF network element to forward the first perception service request to the access side device. The AMF network element receives the first perception service request sent by the SF-C network element, and sends the first perception service request to the access side device. The access side device receives the first perception service request forwarded by the AMF network element.

Step 102: obtain a target identifier based on the first perception service request, and establish a transmission bearer based on the target identifier and the application identifier, where the target identifier is used to indicate the establishment of a bearer.

After the access side device receives the first perception service request, it needs to obtain the target identifier. The target identifier can be a user identifier used to establish a transmission bearer, a virtual user code number, or a bearer identifier supported by the core network device. The UE itself has a target identifier (i.e., a user code number). In the embodiment of the present application, the second perception service is sent by the AF network element, and the AF network element itself does not have a target identifier, so the access side device needs to obtain the target identifier.

It should be understood that after the access side device receives the first perception service request, it completes the relevant configuration of the perception task according to the request, such as the scope of the perception operation, the frequency of scanning data, the reporting frequency of the perception data and the reporting format of the perception data, etc. The details are not elaborated here.

In the embodiment of the present application, the access side device supports the capability of actively triggering the establishment of a bearer. For example, when the access side device is a base station, the base station can actively trigger the establishment of a transmission bearer without being triggered based on a request received from a terminal.

It should be understood that the specific manner in which the access side device obtains the target identifier is not limited here. For example, the target identifier may be locally configured by the access side device, may be dynamically obtained by the access side device from the outside, or may be directly issued by the core network device. The following will describe different manners in which the access side device obtains the target identifier.

Optionally, as an optional implementation manner, the acquiring a target identifier based on the first perception service request includes:

Configure the target identifier based on the first perception service request.

In this embodiment, the access side device locally configures the target identifier. Specifically, the access side device allocates the locally configured target identifier for the perception service to establish a transmission bearer for the perception data. In this embodiment, the access side device supports the local configuration of the target identifier, and the obtained target identifier is used to initiate the bearer establishment when the access side device is used as the source point.

Optionally, as another optional implementation, the acquiring a target identifier based on the first perception service request includes:

Send an identification configuration request to a core network device, where the identification configuration request is used to request the core network device to configure the target identification; and receive the target identification sent by the core network device.

Optionally, as another optional implementation, the acquiring a target identifier based on the first perception service request includes:

Send an identification configuration request to an external AF network element, where the identification configuration request is used to request the core network device to configure the target identification; and receive the target identification sent by the core network device.

In this implementation, the access side device dynamically obtains the target identifier from the outside. Exemplarily, the access side device may obtain it from the core network device or from an external AF network element.

It should be noted that the specific selection method of the core network device and the external AF network element is not limited here. Exemplarily, the external AF network element should be a third-party application platform authorized by the core network or with high credibility, so as to ensure the security of data.

Exemplarily, the core network device is an AMF network element, the base station sends an identifier configuration request to the AMF network element, the AMF network element configures the target identifier and sends the target identifier to the access side device, and the access side device receives the target identifier sent by the core network device.

In this implementation, the access side device supports external acquisition of the target identifier, and the acquired target identifier is used to initiate bearer establishment when the access side device serves as a source point.

Optionally, as another optional implementation manner, the first perception service request carries the target identifier, and the acquiring the target identifier based on the first perception service request includes:

The target identifier is obtained from the first perception service request.

In this implementation, the core network device actively sends the target identifier. The specific network element of the core network device is not limited here. Exemplarily, the core network device can be an AMF network element or a SF-C network element.

When the access side device receives the first perception service request sent by the SF-C network element, the SF-C matches the target identifier according to its own local configuration and carries the target identifier in the first perception service request. The access side device can directly obtain the target identifier from the first perception service request.

In the case where the access side device receives the first perception service request forwarded by the SF-C network element through the AMF network element, the SF-C may match the target identifier according to its own local configuration and carry the target identifier in the first perception service request, so that the AMF network element forwards the target identifier when forwarding the first perception service request.

In the case where the access side device receives the first perception service request forwarded by the SF-C network element through the AMF network element, the AMF network element may also match the target identifier according to its own local configuration and carry the target identifier when forwarding the first perception service request.

Optionally, in some embodiments, the second perception service request and the first perception service request also carry the target object and/or operation type of the perception service, and the target object and/or operation type of the perception service is used to determine the access side device that executes the perception service.

The target object of the sensing service is used to characterize the type of data that needs to be sensed, and the operation type of the sensing service is used to characterize whether the sensing service is for an area or a target. For example, if the target object of the sensing service is temperature and the operation type of the sensing service is area, the sensing service is used to sense the temperature in the area. For example, if the target object of the sensing service is humidity and the operation type of the sensing service is target, the sensing service is used to sense the humidity of the target.

It should be understood that the second perception service request carries the target object and/or operation type of the perception service, so the SF-C network element can receive the target object and/or operation type of the perception service and carry the target object and/or operation type of the perception service in the first perception service request. Both the SF-C network element and the AMF network element can determine the access side device that performs the perception service based on the target object and/or operation type of the perception service.

In some embodiments, after the SF-C network element determines the access side device that performs the perception service based on the target object and/or operation type of the perception service, it sends a first perception service request to the access side device, or sends the first perception service request to the access side device through the AMF network element.

In some embodiments, the SF-C network element sends a first perception service request carrying a target object and/or operation type of the perception service to the AMF network element. After the AMF network element determines the access side device that performs the perception service based on the target object and/or operation type of the perception service, it forwards the first perception service request to the access side device.

The specific manner in which the access side device establishes the transmission bearer based on the target identifier and the application identifier is not limited here.

As an optional implementation mode, the access side device carries the target identifier and the application identifier to send a bearer establishment request to the Session Management Function (SMF) network element to establish the bearer. As another optional implementation mode, the access side device carries the target identifier and the application identifier to send a registration and bearer establishment request to the SMF network element, completes the user registration based on the target identifier first, and then establishes the bearer.

It should be understood that, in some embodiments, the bearer establishment request may also carry other parameters such as a task identifier (session ID), which may be configured according to actual conditions and is not limited here.

Step 103: Send a bearer establishment message to the SF-C network element, where the bearer establishment message carries the target identifier and the application identifier.

After the bearer is established, the access side device sends a bearer establishment message to the SF-C network element to inform the SF-C network element that the bearer establishment is complete, and sends information such as the target identifier and application identifier to the SF-C network element. Of course, in the specific implementation, the access side device can also forward the bearer establishment message to the SF-C through the AMF network element, which will not be described in detail here.

It should be understood that the bearer establishment message carries the target identifier and the application identifier, and the SF-C network element stores and associates the target identifier and the application identifier after receiving the message. The SF-C network element stores the target identifier and the application identifier by association, which can be used for subsequent call billing and other aspects.

Step 104: Transmit perception data based on the transmission bearer, where the perception data is data acquired by the access side device when performing the perception service.

The access side device executes the sensing service to obtain the sensing data, and transmits the sensing data based on the established transmission bearer. Exemplarily, the access side device sends the sensing data to the SF-U network element, and the SF-U network element collects and analyzes the sensing data to obtain the sensing result, and sends the sensing result to the AF network element. As an optional implementation, the SF-U network element can also forward the sensing result to the AF network element through the SF-C network element.

In the embodiment of the present application, the perception data is data collected by the access side device itself, so the access side device supports the ability to actively establish a bearer and transmit the perception data acquired by itself. For example, when the access side device is a base station, the base station can establish a transmission bearer as a source point and transmit data.

In an embodiment of the present application, the AF network element sends a first perception service request to the SF-C network element, triggering the SF-C network element to send the first perception service request, and both the first perception service request and the second perception service request carry an application identifier for identifying the AF network element that sends the second perception service request. The access side device obtains the target identifier based on the first perception service request, and establishes a transmission bearer based on the target identifier and the application identifier; sends a bearer establishment message to the SF-C network element; and transmits perception data based on the transmission bearer. In the above manner, when the perception service requester is the AF network element, bearer establishment and perception data transmission can be achieved.

Optionally, in some embodiments, the method further comprises:

receiving a first perception service cancellation request sent by the SF-C network element;

canceling the transport bearer based on the first perception service cancellation request;

Send a bearer cancellation notification to the SF-C network element, where the bearer cancellation notification carries the target identifier and the application identifier.

When the AF network element that initiated the perception service needs to cancel the perception service, the AF network element sends a second perception service cancellation request to the SF-C network element. The SF-C network element receives the second perception service cancellation request sent by the AF network element, and then sends a first perception service cancellation request to the access side device.

The access side device receives the first perception service cancellation request sent by the SF-C network element, cancels the transmission bearer based on the first perception service cancellation request, and sends a bearer cancellation notification to the SF-C network element. The SF-C network element receives the bearer cancellation notification sent by the access side, and sends a perception service cancellation success message to the AF network element. The AF network element receives the perception service cancellation success message sent by the SF-C network element.

It should be understood that the bearer cancellation notification carries the target identifier and application identifier so that the SF-C network element can know the target identifier and application identifier corresponding to the cancelled transport bearer. In the above manner, it is equivalent to releasing the target identifier so that the target identifier can be reconfigured for use by other transport bearers later.

Please refer to Figure 2, which is a second flow chart of a method for transmitting perception data provided by an embodiment of the present invention. The method is applied to and executed by a SF-C network element. As shown in Figure 2, the method specifically includes the following steps:

Step 202: Send a first perception service request to the access side device, where the first perception service request is used to request the access side device to perform a perception service, and the first perception service request carries the application identifier.

Optionally, the second perception service request and the first perception service request also carry a target object and/or an operation type of the perception service, and the target object and/or the operation type of the perception service is used to determine an access side device that executes the perception service.

Optionally, sending the first perception service request to the access side device includes:
