In some embodiments, mobile media services, augmented reality (AR) / virtual reality (VR) and other extended reality (XR) services, cloud games, Services such as remote control of machines or drones using video are expected to contribute increasing amounts of traffic to communication networks, such as 5G networks. XR services involve multimodal data streams. Multimodal data is data that describes the same service / application and is input from the same device or different devices (including sensors), which may be output to one or more destination device terminals. The data streams in multimodal data often have certain or even strong correlations, such as synchronization of audio and video streams, and synchronization of touch and vision. The data streams of this type of media services, the data streams between them, and the network transmission requirements of these service data streams all have some common characteristics. The effective identification and utilization of these characteristics will be more conducive to the transmission and control of networks and services, as well as service assurance and user experience. Extended Reality Media (XRM) services and interactive media services require the 5G system (5GS) to comprehensively consider the QoS characteristics of the relevant data flows of the services, such as the guaranteed bit rate (GBR) data flow with strict delay requirements (delay critical), the guaranteed forwarding burst rate (GFBR), the packet delay budget (PDB), the default maximum data burst volume (MDBV) and other parameters. Whether they can be met and coordinated. It involves multiple XRM data flows of a terminal (also called user equipment (UE)), and the consistency of QoS authorization and execution of XRM data flows of multiple UEs. At present, the QoS processing of multiplexed service data streams of 5GS has enhanced the processing based on the Protocol Data Unit (PDU) set, congestion control, transmission of XRM service ID to PCF for identifying service data streams and other functions. However, it cannot support the XRM service QoS requirements in many network deployment, transmission protocol and service deployment scenarios. For example, it supports the processing of non-encrypted application service data streams based on the protocol data set (PDU set based handling), supports the PDU set function of multiple protocols, and supports QoS enhancements such as multimedia type multiplexing in the same XRM service data stream. In the first aspect, an embodiment of the present disclosure proposes a method for processing a service data flow.

As shown in FIG3A , the method for processing a service data flow may include the following steps: In step S301, first information sent by a second network element is received, where the first information includes a QoS requirement of a multiplexed service data flow.

In some embodiments, the first network element PCF can obtain first information sent by the second network element, where the first information includes Quality of Service (QoS) requirements for multiplexed service data flows, and the PCF can make policy decisions based on the obtained QoS requirements. The second network element may be a network device that undertakes management and control functions of application services, for example, an application function (AF) network element in a core network device. In some embodiments, the first network element PCF may obtain first information sent by the second network element AF, where the first information includes QoS requirements for multiplexed service data flows, and make a policy decision based on the first information. The multiplexed service data stream may refer to a data stream with multiple features multiplexed in a single end-to-end transmission connection, including different media types, connection IDs, stream IDs in the connection, frame types, frame IDs, or specified specific field IDs. The QoS characteristics of PDUs or PDU sets with different characteristics in the data stream are different, and QoS policies and guarantees can be specifically implemented for different QoS characteristics. The PCF makes policy decisions based on the first information, which can be used to determine whether it is necessary to adjust the policy or generate a new policy to identify and map data streams multiplexed with different media types in a single end-to-end connection to corresponding QoS flows. It should be noted that the embodiment shown in FIG. 3A may be implemented independently or in combination with at least one other embodiment in the present disclosure.

Accordingly, the multiplexed service data flows within a single end-to-end connection may be identified and mapped to one or more corresponding QoS flows. In some embodiments, after the first network element PCF obtains the first information sent by the second network element, it can perform policy decisions based on the first information, including: generating or updating policy control and charging (PCC) rules based on the first information. In some embodiments, after executing a policy decision based on the first information, the first network element PCF may send second information to the second network element AF, where the second information includes response information to the QoS requirement carried by the first information.

In some embodiments, after receiving the fifth information from the SMF, the UPF can perform traffic detection based on the fifth information to identify the QoS characteristics of PDUs or PDU sets with different characteristics in the data flow, and based on the fifth information and the traffic detection results, map the multiplexed data streams of different media types within a single end-to-end transmission connection into one or more QoS flows. In some embodiments, the UPF may perform traffic detection and map multiplexed data streams of different media types within a single end-to-end transport connection into one or more QoS flows based on the received fifth information, the configuration of operations, administration, and maintenance (OAM), and usage policies. In some embodiments, after the fourth network element SMF receives the third information sent by the first network element PCF, in order to be able to make corresponding modifications to the session based on the third information, the SMF may also send sixth information to the seventh network element, where the sixth information is used to indicate the QoS rules and / or QoS group parameters, so that the seventh network element sends the sixth information to the terminal through the access network device (Radio Access Network / Access Network, RAN / AN). Among them, the seventh network element is a network device that processes user access and mobility management, for example, it can be an access and mobility management function (Access and Mobility Management Function, AMF) network element in the core network device. For example, SMF can send the sixth message to AMF through Namf_Communication_N1N2MessageTransfer. In some embodiments, the sixth information may include at least one of the following: a protocol data unit session identifier (PDU session ID); a quality of service flow identifier (QoS Flow ID, QFI); a quality of service contract document (QoS Profile); and an N1 session management container (N1 SM container).

The access network device can send an N2 PDU Session Ack message to the AMF as a response message to the N2 PDU Session Request. In some embodiments, AMF may forward information received from the access network device to SMF by sending seventh information via SMF, wherein the seventh information is used to indicate resource settings performed by the terminal based on the sixth information. For example, AMF may forward information received from the access network device to SMF via Nsmf_PDUSession_UpdateSMContext. In some embodiments, after receiving the seventh information sent by AMF, the fourth network element SMF may send a seventh information to AMF. The eighth information is the response information of the seventh information. For example, after receiving the Nsmf_PDUSession_UpdateSMContext message from the AMF, the SMF may reply to the AMF with Nsmf_PDUSession_UpdateSMContext Response. In some embodiments, the fourth network element SMF can also determine to update the N4 session with the fifth network element UPF based on the seventh information received from the AMF. For example, the SMF can modify the N4 session involved by sending an N4Session Modification Request to the UPF and obtain the N4Session Modification Response replied by the UPF. In the above embodiment, after the PCF makes a policy decision based on the first information provided by the AF and generates or updates the PCC rule, it can send the generated or updated PCC rule to the SMF, so that the SMF indicates the QoS rule and / or the QoS group parameter to the UPF.
