Those skilled in the art can know that the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems as the system architecture evolves and new business scenarios appear.

[0204] The following embodiments of the present disclosure can be applied to the communication system 100 illustrated in FIG. 1A, or a part of the main bodies in the communication system 100, but are not limited thereto. The main bodies illustrated in FIG. 1A are examples, and the communication system 100 can include all or part of the main bodies in FIG. 1A, or other main bodies in addition to those in FIG. 1A. The number and form of the main bodies are arbitrary. The main bodies can be physical or virtual. The connection relationship between the main bodies is an example. The main bodies can not be connected or can be connected. The connection can be in any manner, can be direct or indirect, and can be wired or wireless.

[0205] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0206] In some cases, mobile media type services, XR services such as online AR / VR, online games, video-based machine or drone remote control, etc. are expected to contribute to an increasingly high traffic for the communication network. XR services involve multi-modal data flows. Multi-modal data is data input from the same device or different devices (including sensors) that describe the same service / application, which can be output to one or more destination device terminals. Each data flow in multi-modal data often has certain or even strong correlation, such as synchronization of audio and video streams, synchronization of haptics and vision, etc. There are some common characteristics in the data flow of such media services, between the data flows, and the requirements of these service data flows for network transmission. Effective identification and utilization of these characteristics will be more helpful for network and service transmission, control, and also for service guarantee and user experience.

[0207] In further cases, XRM services and interactive media type services (eXtended Reality and interactive media services) require the communication system to comprehensively consider the QoS characteristics of service data flows. The QoS characteristics include, for example, at least one of the following: whether delay-sensitive guaranteed bit rate (GBR) data flows, guaranteed flow bit rate (GFBR), packet delay budget (PDB), default maximum data burst volume (MDBV), etc. can be simultaneously satisfied and consistently coordinated. The consistency of QoS authorization and execution of each other for multiple XRM data flows involving one terminal and XRM data flows involving multiple terminals is guaranteed.

[0208] In some embodiments, the service data flow (SDF) of XRM can support PDU set-based processing, thereby enhancing QoS awareness and guarantee of SDF and enhancing the quality of experience (QoE) of users.

[0209] In some embodiments, in a system such as 4G, 5G, 6G, V2X, an AF can provide PDU set QoS parameters and protocol description. In some embodiments, the PDU set QoS parameters can include at least one of: PDU set delay budget (PSDB), PDU set error rate (PSER), PDU Set Integrated Handling Information (PSIHI). Then, the SMF and UPF can extend the packet header of the PDU in the PDU set of the SDF in combination with the protocol description provided by the AF and the protocol header extension to carry the PDU set information. The carried PDU information can be used by the access network for PDU set based QoS control.

[0210] In some embodiments, the PDU set information described above can include at least one of: PDU set sequence number, start PDU or end PDU of the PDU set, PDU sequence number within the PDU set, number of PDUs within the PDU set, PDU set importance, PDU set size. Here, the PDU set importance is used to represent the importance of a PDU set relative to other PDU sets in the same QoS flow.

[0211] It can be understood that the UPF performs SDF to QoS flow mapping based on the PDR, and maps (also can be referred to as encapsulates) the mutually associated PDUs into a PDU set. In addition, the UPF can apply the same QoS policy to all PDU sets within the QoS flow. For example, the UPF can apply the same PDU set QoS parameters to all PDU sets within the QoS flow. In an example, the UPF can map an application flow to a QoS flow based on the packet detection information in the PDR. Some PDUs in the QoS flow can be associated with media components (e.g., intra-coded frames and predicted frames), and the UPF classifies these PDUs as belonging to a PDU set and performs corresponding control. In some embodiments, the RAN can implement PDU set based processing according to the PDU set specific QoS characteristics and protocol description provided by the 5GC and the AF, and the enhanced header identified and marked by the UPF.

[0212] In some embodiments, in a large number of application scenarios, pose information is used to achieve consistency between the movement of the user in the real environment and the movement in the virtual scene. In order to maintain such consistency, the application can select a reference frame to implement tracking of the real world. The virtual scene provides the relationship between the physical environment of the user and other tracked entities.

[0213] In some embodiments, a pose can be used to represent a position and / or an attitude of an object in a space (e.g., a real space or a virtual space). The pose can be, for example, an XR pose. In some embodiments, the pose information can be spatial information. In some embodiments, the pose information can include at least one of: position information, orientation information. The position information can be used to indicate a position of an object in a space, e.g., position domain information x, y, z. The orientation information can be used to indicate an orientation of an object in a space, e.g., orientation domain rx, ry, rz, rw.

[0214] In some embodiments, when implementing an XRM service, the pre-rendered video stream sent to the terminal can include pose information to indicate a pose for rendering media.

[0563] Hereinafter, the embodiments of the present disclosure are exemplarily described through specific implementations.

[0564] In some embodiments, the policy request, authorization and implementation mechanism for the pose information can support immersive communication.

[0565] FIG. 9A is an interaction schematic diagram of an exemplary implementation of a communication method according to an embodiment of the present disclosure. As shown in FIG. 9A, the communication method is implemented through multiple steps.

[0566] In some embodiments, the interaction process in FIG. 9A involves a UE, a consumer, a first control plane (CP) network function (NF), a second CP NF, a third CP NF, a first user plane (UP) NF, an NEF, and a DN / AF.

[0567] In some embodiments, the consumer (or consumer NF) in the present embodiment can be a RAN. In some embodiments, the consumer can refer to an object to which a service is provided. For example, in a service-based scenario, a service can be provided to a consumer. In some embodiments, the information and / or parameters provided by the AF and / or PCF for monitoring and / or reporting of the first parameter can be provided to the RAN. In this case, the RAN can be considered as a consumer. It can be understood that the consumer can be independent of a device. The object to which the service is provided is the consumer.

[0568] In some embodiments, the first CP NF can be a PCF. In some embodiments, the second CP NF can be a SMF. In some embodiments, the third CP NF can be an AMF. In some embodiments, the first UP NF can be a UPF.

[0569] In step 1, the AF (i.e., the second network element) sends an AF session resource request (i.e., the first message), such as an Nnef_AFsessionWithQoS_Create request, to create an AF request. The AF carries the QoS requirements of the XRM service and interactive media class service data flow in the request message.

[0570] In some embodiments, the AF provides QoS requirements for media streams. The QoS requirements (i.e., first information) include an XR pose information support indication, and XR pose information (spatial position and / or direction relative to an XR space). The XR pose information support indication can indicate XR pose support. The XR pose information support indication and the XR pose information can be used as inputs for PCC determination.

[0571] In some embodiments, the XR pose information can include at least one of the following:

[0572] - an XR pose support indication;

[0573] - network support for predicted poses;

[0574] - a 6DoF XR pose (i.e., the XR pose includes a position domain x, y, z and a direction domain rx, ry, rz, rw);

[0575] - a 3DoF XR pose (i.e., the XR pose does not include a position domain x, y, z);

[0576] - an XR pose used with a video stream;

[0577] - an XR pose used with an audio stream;

[0578] - an XR pose used with a haptic stream;

[0579] - RTP HE is used to deliver the XR pose;

[0580] - an XR pose for one or more UEs;

[0581] - an XR pose group, and can be a group identification of XR poses (e.g., multiple media streams can multiplex the poses provided in one media stream or in one substream of a multiplexed stream);

[0582] - a priority or a priority list of XR pose support (e.g., related to QoS configuration).

[0583] In some embodiments, the AF can provide the above information to the core network (e.g., NEF / PCF) in the AF QoS request / update procedure.

[0584] In some embodiments, the XRM traffic information can be carried, which identifies the XRM traffic data stream or data stream group (e.g., a multi-modal traffic ID), UE address / UE identifier, AF identifier, application ID, stream description, DNN, S-NSSAI, QoS parameters, and the like corresponding information. Here the multi-modal traffic ID can be used to identify all flows in the XRM traffic group.

[0585] In step 2, the NEF (i.e. the seventh network element) authorizes the AF request. If it is a non-trusted AF, the NEF sends the AF's request to the PCF (i.e. the first network element) via the NEF. (Optionally, the NEF performs relevant mapping, including mapping of the XRM service (AF service identifier) to DNN and S-NSSAI, mapping of external application to core network application identifier; and mapping of external UE identifier to core network UE identifier (such as SUPI) based on UDM subscription information, and mapping of external to internal XRM service group identifier according to UDM subscription information).

[0586] In step 3, the NEF authorizes the AF request and determines whether to cause the TSCTSF or directly contact the PCF according to the parameters provided by the AF. These signaling steps can refer to the AF session with required QoS procedure. The PCF receives the attributes provided by the AF from the NEF or the TSCTSF. The NEF triggers the Npcf_PolicyAuthorization_Create to send the AF request to the PCF, carrying the QoS requirement information for the PCF to make a policy decision.

[0587] In some embodiments, the message carries an XR pose support indication indicating that the corresponding SDF supports XR pose support, and XR pose information (spatial position and / or direction relative to the XR space).

[0588] In step 4, the PCF makes a policy decision. The PCF can determine that the updated or new policy information needs to be sent to the SMF.

[0589] In some embodiments, the PCF authorizes the service data flow in the PCC rule, taking into account the XR pose support indication indicating that the XR pose support, and the XR pose information (spatial position and / or direction relative to the XR space) provided by the AF, and / or the local operator configuration (e.g. priority or priority list of XR pose support, 6DoF or 3DoF XR pose with priority, flow group support, etc.).

[0590] In some embodiments, the PCF can determine the PCC rule (i.e. the first rule) taking into account the XR pose support indication indicating that the XR pose support, and the XR pose information. The PCF can send the authorized XR pose information support (i.e. the second information) to the SMF via the PCC rule.

[0591] In some embodiments, the authorized XR pose information support can include at least one of the following:

[0592] - the XR pose support indication;

[0593] - the network supports predictive pose;

[0594] - 6DoF XR pose (i.e. XR pose includes position domain x, y, z and orientation domain rx, ry, rz, rw);

[0595] - 3DoF XR pose (i.e. XR pose does not include position domain x, y, z);

[0596] - XR pose used with video stream;

[0597] - XR pose used with audio stream;

[0598] - XR pose used with haptic stream;

[0599] - RTP HE is used to transfer XR pose;

[0600] - XR pose for one or more UEs;

[0601] - XR pose group and can be a group identification of XR poses (e.g. multiple media streams can multiplex the poses provided in one media stream or in one substream of a multiplexed stream);

[0602] - Priority or priority list supported by XR pose (e.g. related to QoS configuration).

[0603] In step 5, the PCF sends Npcf_PolicyAuthorization_Create response to the NEF in response.

[0604] In step 6, the NEF sends Nnef_AFsessionWithQoS_Create response message to the AF with the result to inform whether the request is authorized or not.

[0605] In step 7, the PCF initiates SM Policy Association Modification request to the SMF with the PCC rules.

[0606] In some embodiments, based on the PCC rules from the PCF, the SMF (i.e. third network element) generates and provides the QoS configuration and along with the authorized QoS parameters to the NG-RAN (i.e. first device).

[0607] In some embodiments, the SMF instructs the UPF (i.e., fourth network element) to identify / detect XR pose information (e.g., orientation quaternion coordinates of XR pose, position coordinates of XR pose, pose information object array, pose time, etc.), map or mark the XR pose information into an extended header, and send to a consumer network function for QoS adjustment or QoS enforcement. In some embodiments, the SMF configures / activates the rules to the UPF (e.g., through N4 session).

[0608] In step 8, in response, the SMF sends an SM Policy Association Modification response to the PCF.

[0609] In step 9, the SMF initiates an N4 Session Modification request (XR pose information) to the UPF.

[0610] In step 10, the UPF responds to the SMF.

[0611] In some embodiments, the first UP NF / UPF detects XR pose information (e.g., orientation quaternion coordinates of XR pose, position coordinates of XR pose, pose information object array, pose time, etc.), maps or marks the XR pose information into an extended header, and sends to a consumer network function (e.g., through GTP-U header to NG-RAN) for QoS adjustment or QoS enforcement.

[0612] In some embodiments, in case the data network (DN) does not provide the XR pose information through control plane and user plane, the operation of mapping or marking the XR pose information into an extended header can be implemented based on operation administration and management (OAM) configuration of the UPF.

[0613] In some embodiments, based on OAM configuration or operator policy, the first UP NF / UPF identifies XR pose information (e.g., orientation quaternion coordinates of XR pose, position coordinates of XR pose, pose information object array, pose time, etc.), maps or marks the XR pose information into an extended header, and sends to a consumer network function (e.g., through GTP-U header to NG-RAN) for QoS adjustment or QoS enforcement.

[0614] In step 11, for the modification requested by the SMF, the SMF causes a Namf_Communication_N1N2MessageTransfer (N2 SM information (PDU session ID, QFI, QoS configuration, N1 SM container)).

[0615] In step 12, the AMF (i.e., the sixth network element) can send an N2 message (N2 SM information received from the SMF, NAS message (PDU session ID, N1 SM container (PDU session modification command))) to the RAN.

[0616] In step 14, the RAN can acknowledge the N2 PDU session request by sending an N2 PDU session acknowledgment (Session Ack) message to the AMF.

[0617] In some embodiments, the NG-RAN can adjust the QoS parameters in consideration of the mapped or tagged XR pose information from the first UP NF / UPF.

[0618] In some embodiments, with this QoS adjustment considering the XR pose information, the data of the QoS flow (or QoS flow group) can be timely sent.

[0619] In step 15, the AMF forwards the N2 SM information from the access network to the SMF through the Nsmf_PDUSession_UpdateSMContext service operation.

[0620] In step 16, the SMF replies with the Nsmf_PDUSession_UpdateSMContext response.

[0621] In steps 17 and 18, the SMF can update the N4 session of the UPF involved in the PDU session modification by sending an N4 Session Modification Request to the UPF.

[0622] FIG. 9B is an interaction schematic diagram of an exemplary implementation of a communication method according to embodiments of the present disclosure. As shown in FIG. 9B, the communication method is implemented through a plurality of steps.

[0623] In step 1a, steps 1 to 7a in the PDU session establishment procedure are performed.

[0624] In step 1b, the AF can send information (QoS parameters for each PDU set within the QoS flow, and frame identification parameters) to the PCF through the Nnef_AfsessionWithQoS_Create request. The AF can also provide these information to the 5GS before the PDU session establishment.

[0625] In some embodiments, the AF provides QoS requirements for the media stream. The QoS requirements include an XR pose information support indication, and XR pose information (spatial position and / or direction relative to an XR space). The XR pose information support indication can indicate XR pose support. The XR pose information support indication and the XR pose information can be used as inputs for PCC determination.

[0626] In some embodiments, the XR pose information can include at least one of the following:

[0627] - an XR pose support indication;

[0628] - network support for predicted pose;

[0629] - 6DoF XR pose (i.e., the XR pose includes a position domain x, y, z and a direction domain rx, ry, rz, rw);

[0630] - 3DoF XR pose (i.e., the XR pose does not include a position domain x, y, z);

[0631] - XR pose used with a video stream;

[0632] - XR pose used with an audio stream;

[0633] - XR pose used with a haptic stream;

[0634] - RTP HE is used to deliver XR pose;

[0635] - XR pose for one or more UEs;

[0636] - a group of XR poses, and can be a group identification of XR poses (e.g., multiple media streams can multiplex the poses provided in one media stream or in one substream of a multiplexed stream);

[0637] - a priority or a list of priorities of XR pose support (e.g., related to QoS configuration).

[0638] In some embodiments, the AF can provide the above information to the core network (e.g., NEF / PCF) in the AF QoS request / update procedure.

[0639] In some embodiments, the AF can provide the protocol description and PDU set related assistance information. The PDU set related assistance information can include QoS parameters per QoS set within a QoS flow. The QoS parameters include at least one of: PDU set handling indication, whether the application layer usage of the PDU set requires all PDUs, PDU set delay budget, PDU set error rate. In some embodiments, the PDU set handling indication can be used to indicate whether PDU set based processing is activated for the flow. This indication can be implicitly indicated by other PDU set related information provided by the AF.

[0640] In step 2, the PCF generates appropriate PCC rules. The PCC rules can include PDU set related QoS parameters. The PCF can send the PCC rules to the SMF.

[0641] In some embodiments, the PCF authorizes traffic data flows in the PCC rules, taking into account the XR pose support indication indicating XR pose support, and the XR pose information (spatial position and / or direction relative to XR space), and / or local operator configuration (e.g., priority or priority list of XR pose support, 6DoF or 3DoF XR pose with priority, flow group support, etc.).

[0642] In some embodiments, the PCF can determine the PCC rules, taking into account the XR pose support indication indicating XR pose support, and the XR pose information. The PCF can send the authorized XR pose information support to the SMF through the PCC rules.

[0643] In some embodiments, the authorized XR pose information support can include at least one of:

[0644] - XR pose support indication;

[0645] - network support predicted pose;

[0646] - 6DoF XR pose (i.e., XR pose includes position domain x, y, z and orientation domain rx, ry, rz, rw);

[0647] - 3DoF XR pose (i.e., XR pose does not include position domain x, y, z);

[0648] - XR pose used with video stream;

[0649] - XR pose used with audio stream;

[0650] - XR pose used with haptic stream;

[0651] - RTP HE used for delivering XR pose;

[0652] - XR pose for one or more UEs;

[0653] - XR pose group, and can be a group identification of XR poses (e.g., multiple media streams can multiplex the poses provided in one media stream or in one substream of a multiplexed stream);

[0654] - Priority or priority list of XR pose support (e.g., related to QoS configuration).

[0655] In some embodiments, the PDU set related QoS parameters can be new QoS parameters for PDU set based QoS handling in 5GS, and can include at least one of: whether the application layer usage of the PDU set requires all PDUs, PDU set delay budget, PDU set error rate, whether to discard the PDU set when the PDU set delay budget is exceeded.

[0656] In some embodiments, step 2 can be completed by part of the steps in PDU session establishment procedure, PDU session modification procedure.

[0657] In some embodiments, step 2 can be triggered by step 1b, and the PCF can consider the information provided by the AF to generate the PCC rules.

[0658] In step 3, the SMF generates QoS configuration and N4 rules based on the PCC rules from the PCF. The SMF sends the N4 rules to the UPF and sends the QoS configuration to the RAN through the AMF.

[0659] In some embodiments, based on the PCC rules from the PCF, the SMF generates and provides the QoS configuration, and provides it to the NG-RAN along with the authorized QoS parameters.

[0660] In some embodiments, the SMF instructs the UPF to identify / detect XR pose information (e.g., orientation quaternion coordinates of XR pose, position coordinates of XR pose, pose information object array, pose time, etc.), map or mark the XR pose information into an extended header, and send it to a consumer network function to implement QoS regulation or QoS enforcement. In some implementations, the SMF configures / activates rules to the UPF (e.g., through N4 session).

[0661] In some embodiments, step 3 can be completed by part of the steps in PDU session establishment procedure, PDU session modification procedure.

[0662] In step 4, the remaining steps in the PDU session establishment procedure, PDU session modification procedure are performed.

[0663] In step 5, based on the received N4 rules or local configuration, the UPF identifies relevant information and performs QoS processing based on the PDU set according to the N4 rule instructions.

[0664] In some embodiments, the first UP NF / UPF detects XR pose information (e.g., XR pose orientation quaternion coordinates, XR pose position coordinates, pose information object array, pose time, etc.), maps or marks the XR pose information into an extended header, and sends it to the consumer network function (e.g., sends it to NG-RAN via a GTP-U header) to implement QoS adjustment or QoS enforcement.

[0665] In some embodiments, where the DN does not provide XR pose information through the control plane and user plane, the operation of mapping or marking the XR pose information to the extended header can be implemented based on the OAM configuration of the UPF.

[0666] In some embodiments, based on OAM configuration or operator policy, the first UP NF / UPF identifies XR pose information (e.g., XR pose orientation quaternion coordinates, XR pose position coordinates, pose information object array, pose time, etc.), maps or marks the XR pose information into an extended header, and sends it to the consumer network function (e.g., sends it to NG-RAN via a GTP-U header) to achieve QoS adjustment or QoS implementation.

[0667] In some embodiments, the PDU set information in the extension header may include at least one of the following: PDU set sequence number, starting or ending PDU of the PDU set, PDU sequence number within the PDU set, number of PDUs within the PDU set, importance of the PDU set, size of the PDU set, and end of data burst.

[0668] In some embodiments, the UPF can identify relevant information through at least one of the following methods and / or mechanisms: matching of RTP / SRTP headers and payloads; new RTP extension headers; information contained in N6 encapsulation headers; detection of flow characteristics; and UPF implementations of non-standardized mechanisms.

[0669] In step 6, the UPF sends PDU set information to the RAN. The UPF sends the aforementioned PDU set information to the RAN. The UPF can add the PDU set information to the GTP-U header.

[0670] In step 7, based on the received PDU set information, the RAN can perform QoS processing based on the PDU set.

[0671] In some embodiments, NG-RAN may adjust QoS parameters by taking into account XR pose information from the mapping or tagging of the first UP NF / UPF.

[0672] In some embodiments, with this QoS adjustment considering XR pose information, data of the QoS flow (or QoS flow group) can be timely sent.

[0673] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or combined with optional implementation manners of other embodiments.
