Description

[Technical Field]

[0001] The present disclosure relates to the field of wireless communication technology, but is not limited to the field of wireless communication technology, and more particularly to a method, apparatus, communication device and storage medium for subscribing to QoS monitoring measurements. [Background technology]

[0002] Extended Reality Media (XRM) services must comprehensively consider the Quality of Service (QoS) characteristics of the service's associated data flows. QoS authorization and enforcement between multiple XRM data flows on one device and between XRM data flows on multiple devices must be consistent. The related technical requirements support QoS detection and coordination for multiple data flows of an XRM service by an application function (AF) and ensure consistency of XRM service QoS policies in a non-real-time manner by updating the corresponding sessions. However, accurate coordination of multiple data flows cannot be achieved because the actual QoS requirements of multiple service data flows (SDFs) and the real-time QoS coordination status of multiple flows in the network cannot be detected.

[0032] To better understand the embodiments of the present disclosure, a related scene is described below.

[0033] Mobile media services, XR services such as cloud augmented reality (AR) and virtual reality (VR), cloud gaming, and services such as remote control of video-based machines and drones are expected to increasingly drive traffic to 5G (5th Generation Mobile Communication Technology) networks. XR services involve multimodal data flows. Multimodal data is data describing the same service or application, input from the same or different devices (including sensors), and this data may be input to one or more target device terminals. Data flows within multimodal data often have certain or strong correlations, such as synchronization between audio and video streams or synchronization between haptic and visual senses. The data flows of such media services, their respective data flows, and their network transmission needs share several common characteristics. Effective identification and utilization of these characteristics can improve network and service transmission and control, thereby ensuring service security and enhancing user experience.

[0034] XRM multi-flow cooperative QoS characteristics (e.g., two-way delay, differential delay, and SDF delay jitter) require the network to support QoS monitoring of multiple SDFs and unified subscription and reporting of corresponding QoS characteristics, which more accurately and effectively supports dynamic QoS awareness and cooperation across multiple SDFs in XRM services by AF. In actual service networks, the state of multi-stream QoS parameters, such as multi-SDF delay and jitter, changes dynamically and continuously due to various network influences. Therefore, the real-time or near-real-time delay state of the network and the real-time delay requirements of the AF service directly affect the QoS authorization of each data flow and the success of supporting 5GS XRM service features.

[0035] In the related art, the 5GS system does not have a unified mechanism to support QoS monitoring of multiple SDFs, such as delay difference monitoring between two or more SDFs in the same direction, bidirectional delay measurement monitoring between two SDFs, and jitter of SDFs. As a result, the AF cannot recognize the actual QoS needs of the multiple SDFs of a service and cannot update based on the received monitoring report to accurately realize multi-flow coordination.

[0036] As shown in FIG. 1b, this embodiment provides a QoS monitoring measurement subscription method, which includes the following steps 11 to 16.

[0037] In step 11, the first network function sends first request information to the second network function, wherein the first request information is used to request a subscription to quality of service (QoS) monitoring measurements obtained by monitoring the QoS of at least two service data flows (SDFs).

[0038] In step 12, after receiving the first request information, the second network function sends the authorized QoS monitoring policy information to a third network function, and the QoS monitoring policy information is used to monitor the quality of service (QoS) of at least two service data flows (SDFs).

[0039] In step 13, after receiving the QoS monitoring policy information, the third network function sends QoS reporting rule information to the RAN and / or the fourth network function.

[0040] In step 14, the fourth network function obtains a QoS monitoring report based on the QoS reporting rule information and sends the QoS monitoring report to the third network function.

[0041] In step 15, after receiving the QoS monitoring report, the third network function sends the QoS monitoring report to the second network function.

[0042] In step 16, after receiving the QoS monitoring report, the second network function sends the QoS monitoring report to the first network function.

[0043] In one embodiment, the first network function may be an AF, the second network function may be a PCF, the third network function is an SMF, and the fourth network function is a UPF.

[0178] As will be understood by those skilled in the art, the methods provided by the embodiments of the present disclosure may be performed alone or together with several methods of the embodiments of the present disclosure or several methods of related art.

[0179] As shown in FIG. 18, this embodiment provides a system, which includes a first network function 181, a second network function 182, a third network function 183, and a fourth network function 184, wherein the first network function 181 is used to realize the method realized by the first network function 181 described in the present disclosure, the second network function 182 is used to realize the method realized by the second network function 182 described in the present disclosure, the third network function 183 is used to realize the method realized by the third network function 183 described in the present disclosure, and the fourth network function 184 is used to realize the method realized by the fourth network function 184 described in the present disclosure.

[0180] To better understand the embodiments of the present disclosure, the technical solution of the present disclosure will be further described below by one exemplary embodiment.

[0181] As shown in FIG. 19, this embodiment provides a QoS monitoring measurement subscription method, which includes the following steps 1901 to 1916.

[0182] In step 1901, the AF sends an AF session resource request, for example, creates an AF request (corresponding to first request information) via an Nnef_AFsessionWithQoS_Create request. Specifically, the AF sends the first request information to a second network function, where the first request information is used to request a subscription to QoS monitoring measurements obtained by monitoring the Quality of Service (QoS) of at least two Service Data Flows (SDFs). In response, the AF receives a subscription report sent from the second network function, where the subscription report is used to instruct the QoS monitoring measurements.

[0183] Exemplarily, it carries XRM service information, common ID information for identifying the XRM service data flow group, and corresponding information such as UE address or UE Identifier, AF Identifier Application ID, Flow description(s), DNN, S-NSSAI, QoS parameters, etc. Here, the common ID may be used to identify all flows in the XRM service group.

[0184] In one embodiment, the AF further sends QoS monitoring information to the PCF. Exemplarily, the QoS monitoring information may be included in the first request information. Exemplarily, the first request information is sent to a second network function, the first request information being used to request a subscription to QoS monitoring measurements obtained by monitoring the Quality of Service (QoS) of at least two Service Data Flows (SDFs), the first request information including the QoS monitoring information, and the QoS monitoring information being used to monitor the Quality of Service (QoS) of the at least two Service Data Flows (SDFs).

[0185] In one embodiment, the QoS monitoring information indicates at least one of an associated identifier, a QoS monitoring keyword, a monitoring mode, a monitoring type, a QoS monitoring level, a delay threshold for an SDF, a time difference threshold between SDFs, a maximum allowable delay jitter threshold for an SDF, a start or end time for QoS monitoring, a concurrent execution instruction for QoS monitoring, a concurrent reporting instruction for QoS monitoring, and a reset period for QoS monitoring.

[0186] In step 1902, the NEF authorizes the AF request. In the case of an untrusted AF, the AF request is sent to the PCF through the NEF. (Illustratively, the NEF performs relevant mappings, including mapping from the XRM service identifier (AF-Service-Identifier) ​​to the DNN and S-NSSAI, mapping from external application to CN application identifier, contract information based on the UDM, mapping from external UE identifier to CN UE identifier (e.g., SUPI), and mapping from external to internal XRM service group identifier based on the UDM contract information.)

[0187] In step 1903, the NEF triggers an Npcf_PolicyAuthorization_Create request to send an AF request to the PCF, carrying QoS requirement information for the PCF to make a policy decision. The message carries the corresponding joint QoS subscription information.

[0188] In step 1904, the PCF determines the monitoring policy, and the PCF may decide to send updated or new policy information to the SMF.

[0189] In step 1905, the PCF sends an Npcf_Policy Authorization_Create response to the NEF.

[0190] In step 1906, the NEF sends a Nnef_AFsessionWithQoS_Create response message to the AF.

[0191] In step 1907, the PCF initiates an SM policy related modification request (PCC rule (QoS monitoring policy)) to the SMF. The SMF generates QoS monitoring configuration for the UPF (plus the RAN if necessary) based on the QoS monitoring policy for measurements from the PCF, as described in step 194.

[0192] In step 1908, the SMF returns an SM policy related modification response to the PCF.

[0193] In step 1909, the SMF initiates an N4 session modification request (QoS monitoring settings shown in Table 1 below) to the UPF.

[0194] [Table 1]

[0195] In step 1910, after receiving the QoS monitoring configuration, the UPF enables measurement and reporting. The UPF responds to the SMF.

[0196] In step 1911, for the modifications requested by the SMF, the SMF calls Namf_Communication_N1N2MessageTransfer([N2 SM Information](PDU Session ID, QFI, QoS Profile, QoS Monitoring Settings), N1 SM Container)).

[0197] In step 1912, the AMF can send an N2([N2 SM information received from SMF], NAS message(PDU Session ID, N1 SM container(PDU Session Modification Command))) message to the (R)AN. Upon receiving the QoS monitoring configuration, the RAN enables event measurement and reporting (e.g., the RAN detects UL delay and DL delay, and the sum of the UL PDB and DL PDB is the RT latency).

[0198] In step 1913, resources are set.

[0199] In step 1914, the (R)AN may acknowledge the N2 PDU session request by sending an N2 PDU Session Ack message to the AMF.

[0200] In step 1915, the AMF forwards the N2 SM information received from the AN to the SMF via the Nsmf_PDUSession_UpdateSMContext service operation.

[0201] In step 1916, the SMF responds with a Nsmf_PDUSession_UpdateSMContext response.

[0202] The SMF can update the N4 session of the UPF related to the PDU session modification by sending an N4 session modification request message to the UPF.
