Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology, and in particular to a method, system, perception terminal, AMF network element, SMF network element, device, medium and computer program product for establishing a perception service session. Background Art

[0002] A perception terminal refers to a device capable of perceiving environmental information, such as various sensors and smart devices. The process of uploading service data from a perception terminal involves transmitting a request related to the perception service on the control plane, along with relevant information from the data plane. This allows the perception terminal to effectively establish a session with the corresponding data plane unit, ultimately transmitting the service request and control instructions on the control plane. Simultaneously, the perception data is transmitted on the data plane, and the data plane performs a certain degree of processing on the perception data, achieving overall efficiency and simplification of the perception service.

[0003] Because perception services are characterized by the sheer volume of raw data, centrally deploying the relevant core network elements in a single, centralized manner would place enormous transmission pressure on the entire control plane of the core network. This is typically achieved by effectively separating the perception network elements into centralized units (CUs). However, this separation requires an effective coordination mechanism between the control and data plane units, and no optimal solution has yet been proposed in the relevant technologies.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0043] S202: Receive a perception service request message, where the perception service request message carries an identifier of a first perception network element.

[0044] In one implementation of the present disclosure, the first perception network element may refer to a perception user plane network element separated from a perception function network element, which may be regarded as a distributed data pipeline, mainly used to carry out the transmission and processing of perception service data. In some scenarios, it may be deployed separately, and in other scenarios, it may be directly deployed in coordination with the UPF network element.

[0045] S204, send a session establishment request message to the access and mobility management function AMF network element, wherein the session establishment request message is used to request the session management function SMF network element to generate a session configuration message, and the session establishment request message carries the identifier of the perception terminal and the identifier of the first perception network element.

[0047] S206, receive the session establishment response message sent by the AMF network element, wherein the session establishment response message carries session configuration information, and the session configuration information is generated by the SMF network element based on the relevant information of the perception terminal and the relevant information of the first perception network element.

[0048] In one embodiment of the present disclosure, the session configuration information is configuration information necessary for the perception terminal to establish a perception session, and mainly involves relevant configuration information of the selected UPF.

[0049] S208: Establish a perception session according to the session configuration information, where the perception session is used to upload perception service data to the first perception network element.

[0050] In one embodiment of the present disclosure, after obtaining the session configuration information, the perception terminal establishes a perception session with the first perception network element through the UPF network element, and executes the perception service based on this, and uploads the perception service data collected by the perception service to the corresponding first perception network element.

[0051] As can be seen from the above, after receiving the perception service request message, the perception terminal in the embodiment of the present disclosure carries the first perception network element identifier and the perception terminal identifier in the session establishment request message, sends it to the AMF network element, and the AMF network element forwards it to the SMF network element, receives the session establishment response message sent by the AMF network element and returned by the SMF network element, and establishes a perception session for uploading perception service data to the perception network element based on the session configuration information carried in the session establishment response message.

[0055] In one embodiment of the present disclosure, the perception function network element is separated based on the control plane and the user plane to obtain a first perception network element (SF-U) and a second perception network element (SF-C).

The perception service response message may carry the execution result of the perception service, which is used to trigger the second perception network element and the first perception network element to perform a collaborative processing flow on the perception service data.

[0059] In one embodiment of the present disclosure, the collaborative process between the first and second perception network elements may include: the first perception network element processing received perception service data; the second perception network element confirming the results of the perception service and collaboratively confirming the perception service data processed by the first perception network element.

[0093] In one embodiment of the present disclosure, the awareness session may be used to upload original awareness service data collected by the awareness terminal when executing the awareness service to the awareness user plane network element.

[0094] S508: After the perception terminal uploads all perception service data to the perception user plane network element, it closes the perception session.

[0095] S509: The perception terminal reports the execution result of the perception service to the perception control plane network element.

[0096] In one embodiment of the present disclosure, after the perception session is closed, the perception terminal uploads the results of the current perception service to the perception control plane network element based on the identification of the perception control plane network element. For example, after the perception session is closed, the perception terminal sends a lightweight service execution report to the perception control plane network element, which may include but is not limited to the perception service flag, execution status, timestamp, and identification of the perception user plane network element.

[0097] S510: The perception control plane network element and the perception user plane network element collaboratively process the perception service data and results.

[0098] In one embodiment of the present disclosure, after the perception control plane network element receives the execution result reported by the perception terminal, there are two data processing triggering modes according to the operator's policy and service requirements:

[0099] ① The perception control plane network element sends a service request to the perception user plane network element. The service request is used to instruct the perception user plane network element to process the perception service data and is usually applicable to customized processing scenarios.

[0100] ② The perception user plane network element processes the perception service data to a certain extent according to the local deployment strategy, which is usually applicable to standardized processing scenarios.

[0101] In one embodiment of the present disclosure, the perception user plane network element processes the stored raw perception service data, such as data cleaning and format conversion. After processing the perception service data, the processed results or data are usually sent back to the perception control plane network element to verify the execution of the entire perception service.

[0102] In one embodiment of the present disclosure, after the perception service is completed, there are multiple possible result return situations, for example: when the processed perception data is small (for example, KB level), the perception user plane network element sends the processed data to the perception control plane network element, and the perception control plane network element then sends all perception service results and data back to the application function AF network element through the network open function NEF network element, which is suitable for application scenarios such as sending text reports and small metadata; when the processed perception data is large (for example, GB level), the perception control plane network element may return the perception service result separately, and then provide the perception user plane network element with relevant information of the AF network element (for example, the AF network element address, and in some cases, it may also carry a security token to prevent illegal access). After receiving the information from the AF network element, the perception user plane network element directly sends the perception service data to the AF network element side, which is suitable for application scenarios such as high-definition maps and video streams.

[0103] It should be noted that the above lists only two example result return paths. The return path of the perception service results and data can be adjusted according to actual conditions, and the embodiments of the present disclosure do not make specific limitations on this.

[0104] It should be noted that the size of the processed perception service data volume can be directly predicted by the perception control plane network element based on the data volume reported by the perception terminal, or it can be evaluated in real time by the perception user plane network element, and then the perception control plane network element is requested to confirm the path. It can be decided according to actual conditions, and the embodiments of this disclosure do not make specific restrictions on this.

[0105] In one embodiment of the present disclosure, the existing user plane units capable of carrying large amounts of data transmission can be used to make the cost of deploying awareness service upgrades by operators relatively low, without the need for high-cost upgrades to control plane-related deployments to meet transmission needs.

[0106] In one embodiment of the present disclosure, in some cases, the perception device can directly transmit a large amount of original perception business data; in other cases, the perception device can process the data before transmission. At the same time, the data plane itself has data processing capabilities, and there is no need to force the perception device to process the data in advance to compress the transmission volume of the perception business data, thereby improving data transmission efficiency.
