[0071] Here, the user equipment mentioned above can be considered as the terminal equipment in the following embodiments.

[0072] In some embodiments, the wireless communication system described above may further include a network management device 130.

[0073] Several base stations 120 are connected to network management device 130. Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC).

[0081] To better understand the embodiments of this disclosure, the relevant scenarios are described below:

[0082] Mobile media services, XR services such as cloud augmented reality (AR) and virtual reality (VR), cloud gaming, and video-based remote control of machines or drones are expected to contribute increasingly higher traffic to 5G networks. XR services involve multimodal data streams. Multimodal data describes data input from the same or different devices (including sensors) for the same service or application, which may be output to one or more destination device terminals. The data streams within multimodal data often have some, or even strong, correlations. For example, the synchronization of audio and video streams, or the synchronization of haptic and visual signals. These media service data streams themselves, the relationships between different data streams, and the network transmission requirements of these service data streams all share some common characteristics. Effective identification and utilization of these characteristics will be more helpful for network and service transmission and control, and will also contribute to service assurance and user experience.

[0083] XRM multi-flow collaborative QoS features (e.g., bidirectional latency, latency difference, and SDF latency jitter) require the network to support QoS monitoring of multiple SDFs, as well as unified subscription and reporting of corresponding QoS features. This allows for more accurate and effective support for AF's dynamic QoS awareness and collaboration across multiple SDFs in XRM services. It should be noted that in actual service operations, the latency and jitter of multiple SDFs, and other multi-flow QoS parameters, are dynamically and continuously changing due to various factors in the network. Therefore, the real-time or near-real-time latency status of the network, and the real-time latency requirements of AF services, directly affect the QoS authorization of each data flow, thus impacting the successful support of 5GS XRM service functions.

[0084] In related technologies, the 5GS system lacks a unified mechanism to support QoS monitoring of multiple SDFs, including latency difference monitoring between two or more SDFs in the same direction, bidirectional latency monitoring between two SDFs in opposite directions, and SDF jitter. This results in the AF (Automatic Filtering) being unable to perceive the actual QoS requirements of multiple SDFs in a service, and being unable to accurately update multi-stream coordination based on received monitoring reports.

[0085] like Figure 1b As shown, this embodiment provides a method for subscribing to QoS monitoring results, wherein the method includes:

[0086] Step 11: The first network function sends a first request message to the second network function; wherein, the first request message is used to request the QoS monitoring results obtained by subscribing to and monitoring the QoS of at least two service data streams SDF;

[0087] Step 12: After receiving the first request information, the second network function sends authorized QoS monitoring policy information to the third network function; wherein, the QoS monitoring policy information is used to monitor the quality of service (QoS) of at least two service data streams (SDFs).

[0088] Step 13: After receiving the QoS monitoring policy information, the third network function sends QoS report rule information to the RAN and / or the fourth network function;

[0089] Step 14: The fourth network function obtains the QoS monitoring report based on the QoS report rule information and sends the QoS monitoring report to the third network function.

[0090] Step 15: After receiving the QoS monitoring report, the third network function sends the QoS monitoring report to the second network function.

[0091] Step 16: After receiving the QoS monitoring report, the second network function sends the QoS monitoring report to the first network function.

[0092] In one embodiment, the first network function may be AF; the second network function may be PCF; the third network function may be SMF; and the fourth network function may be UPF.

The fourth network device in this disclosure can be a User Plane Function (UPF), but it can also be any other network device capable of implementing the UPF. No limitations are imposed here.

[0098] In one embodiment, during the QoS request process of the application function AF, the first request information is sent to the second network function; wherein, the first request information is used to request the QoS monitoring results obtained by subscribing to and monitoring the QoS of at least two service data streams SDF.

[0099] In one embodiment, a first request message is sent to a second network function; wherein the first request message is used to request a subscription to monitor the QoS (Quality of Service) monitoring results obtained from monitoring at least two Service Data Flows (SDFs). A subscription notification message is received from the second network function; wherein the subscription notification message is used to indicate the QoS monitoring results.

[0100] In one embodiment, a subscription notification message sent by the second network function is received; wherein the subscription notification message is used to indicate the QoS monitoring result; the QoS monitoring result includes QoS parameters related to latency.

It should be noted that the jitter parameter of the SDF can be the jitter parameter of the same SDF at different times, and is not limited here.

[0102] In one embodiment, a first request message is sent to a second network function; wherein the first request message is used to request QoS monitoring results obtained by subscribing to and monitoring the Quality of Service (QoS) of at least two service data streams (SDFs).

[0106] In this embodiment, a first request message is sent to a second network function. This first request message requests a QoS monitoring result obtained by subscribing to and monitoring the Quality of Service (QoS) of at least two Service Data Streams (SDFs). Here, because the first network function sends the first request message to the second network function to request a QoS monitoring result obtained by subscribing to and monitoring the QoS of at least two Service Data Streams (SDFs), the first network function can obtain the QoS monitoring result sent by the second network function in response to the first request message. Compared to the case where the QoS monitoring result cannot be obtained, the first network function can accurately perform coordination between multiple service data streams based on the QoS monitoring result.

[0239] like Figure 18 As shown, this embodiment provides a system, wherein the system includes a first network function 181, a second network function 182, a third network function 183, and a fourth network function 184; the first network function 181 is used to implement the method implemented by the first network function 181 as described in this disclosure; the second network function 182 is used to implement the method implemented by the second network function 182 as described in this disclosure; the third network function 183 is used to implement the method implemented by the third network function 183 as described in this disclosure; and the fourth network function 184 is used to implement the method implemented by the fourth network function 184 as described in this disclosure.

[0240] To better understand the embodiments of this disclosure, the following exemplary embodiment will be used to further illustrate the technical solution of this disclosure:

[0241] like Figure 19 As shown, this embodiment provides a method for subscribing to QoS monitoring results, wherein the method includes:

[0242] Step 1901: The AF sends an AF session resource request, for example, by creating an AF request (corresponding to the first request information) via Nnef_AFsessionWithQoS_Createrequest. Specifically, the first request information is sent to the second network function; wherein, the first request information is used to request the subscription of QoS monitoring results obtained by monitoring the QoS of at least two service data streams' SDFs. Correspondingly, the subscription notification information sent by the second network function is received; wherein, the subscription notification information is used to indicate the QoS monitoring results.

[0243] For example, the XRM service information includes the common ID identifying the XRM service data flow group, the UE address or UE Identifier, AF Identifier Application ID, Flow description(s), DNN, S-NSSAI, QoS parameters, and other relevant information. Here, the common ID can be used to identify all flows in the XRM service group.

[0244] It should be noted that, in one embodiment, the AF also 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 the second network function; wherein, the first request information is used to request the subscription of QoS monitoring results obtained from monitoring the QoS of at least two service data streams (SDFs); the first request information includes QoS monitoring information; the QoS monitoring information is used to monitor the QoS of at least two service data streams (SDFs).

[0245] In one embodiment, the QoS monitoring information indicates at least one of the following:

[0246] Related markings;

[0247] QoS monitoring keywords;

[0248] Monitoring mode;

[0249] Monitoring type;

[0250] QoS monitoring level;

[0251] SDF latency threshold;

[0252] Time difference threshold between SDFs;

[0253] The maximum allowable delay jitter threshold for SDF;

[0254] Start or end time of QoS monitoring;

[0255] Execute instructions while monitoring QoS;

[0256] Simultaneously report instructions during QoS monitoring; and / or

[0257] QoS monitoring reset cycle.

[0258] Step 1902: NEF Authorizes AF Request. If it is an untrusted AF, the NEF sends the AF request to the PCF. (Example: The NEF performs relevant mappings, including mapping from the XRM service identifier (AF-Service-Identifier) ​​to the DNN and S-NSSAI, mapping from the external application to the CN application identifier; and mapping from the external UE identifier to the CN UE identifier (such as SUPI) based on the UDM subscription information, and performing mapping from the external to the internal XRM service group identifier based on the UDM subscription information.)

[0259] Step 1903: NEF triggers the Npcf_PolicyAuthorization_Create request, sending the AF request to the PCF, carrying QoS requirement information for PCF policy decision-making. The message also carries the corresponding joint QoS subscription information.

[0260] Step 1904: PCF determines the monitoring strategy. PCF can determine whether updated or new strategy information needs to be sent to SMF.

[0261] Step 1905: PCF sends an Npcf_Policy Authorization_Create response to NEF.

[0262] Step 1906: NEF sends an Nnef_AFsessionWithQoS_Create response message to AF.

[0263] Step 1907: The PCF initiates an SM policy association modification request (PCC rule (QoS monitoring policy)) to the SMF. Based on the QoS monitoring policy for measurement from the PCF, the SMF generates a QoS monitoring configuration for the UPF (and RAN, if necessary), as described in step 194.

[0264] Step 1908: SMF replies to PCF with the SM policy association modification response.

[0265] Step 1909: SMF initiates an N4 session modification request to UPF (QoS monitoring configuration, as shown in Table 1 below).

[0266] Table 1:

[0267]

[0268] Step 1910: Upon receiving the QoS monitoring configuration, the UPF enables measurement and reporting. The UPF responds to the SMF.

[0269] Step 1911: For modifications to the SMF request, the SMF calls Namf_Communication_N1N2MessageTransfer([N2 SM information](PDU session ID, QFI, QoS profile, QoS monitoring configuration), N1 SM container).

[0270] Step 1912: The AMF can send an N2 ([N2 SM information received from the 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 UL PDB and DL PDB as the RT wait time).

[0271] Step 1913, Resource Settings.

[0272] Step 1914: (R)AN can confirm the N2 PDU session request by sending an N2 PDU session Ack message to the AMF.

[0273] Step 1915: The AMF forwards the N2 SM information received from the AN to the SMF through the Nsmf_PDUSession_UpdateSMContext service operation.

[0274] Step 1916: SMF responds with the Nsmf_PDUSession_UpdateSMContext response.

[0275] SMF can update the N4 session of the UPF involved in the PDU session modification by sending an N4 session modification request message to the UPF.
