[0247] Figure 1 This is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0248] like Figure 1 As shown, the communication system 100 includes a terminal 101 and a network device 102.

[0249] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0253] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0254] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0264] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0265] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown or a part thereof, but not limited thereto. Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, each entity can be physical or virtual, the connection relationship between the entities is illustrative, the entities can be unconnected or connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0266] The embodiments disclosed herein 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), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0267] Mobile media services, cloud AR / VR and other XR services, 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 device or different devices (including sensors) for the same service / application, 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 the synchronization of audio and video streams, or the synchronization of haptic and visual senses. The data streams of these media services themselves, the relationships between the 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 conducive to network and service transmission and control, and will also contribute to service assurance and user experience.

[0268] Extended Reality and Media (XRM) and interactive media services require 5GS systems to comprehensively consider the Quality of Service (QoS) characteristics of relevant data streams. This includes ensuring that parameters such as delay-critical guaranteed bit rate (GBR) data streams, guaranteed flow bit rate (GFBR), packet delay budget (PDB), and default maximum data burst volume (MDBV) are simultaneously and consistently met. This involves ensuring consistent QoS authorization and execution across multiple XRM data streams from a single User Equipment (UE) and multiple UEs.

[0269] Current 5G systems support enhanced processing capabilities of Application Functions (AFs) for each packet data unit (PDU) set in XRM service data streams. This enhances AF's awareness and assurance of Quality of Service (QoS) for XRM service data streams, as well as improving the user's Quality of Experience (QoE). Specifically, AF provides detailed QoS characteristics and protocol descriptions for each PDU set.

[0270] PDU Set-specific QoS characteristics:

[0271] PDU Set Delay Budget (PSDB);

[0272] PDU Set Error Rate (PSER);

[0273] PDU Set Integrated Handling Information (PSIHI).

[0274] SMF and UPF can combine the Protocol Description and protocol header extensions provided by AF to execute the GTP-U header extension of the corresponding PDU in the corresponding SDF PDUset, carrying PDU Set information. The PDU Set information is used by NG-RAN for QoS processing based on the PDU set. The PDU Set information includes:

[0275] PDU Set Serial Number;

[0276] The last PDU in the PDU Set;

[0277] The serial number of the PDU in the PDU Set;

[0278] PDU Set Size;

[0279] PDU Set Importance is used to identify the relative importance of a PDU set compared to other PDU sets in a QoS flow.

[0280] The RAN can perform PDU set-based processing based on the specific QoS features and protocol descriptions of the PDU Set provided by 5GC and AF, as well as the enhanced packet headers identified and marked by UPF.

[0281] However, 5GS currently only supports PDU set-based processing of unencrypted application service data streams. In actual application deployments, the vast majority of service data streams are encrypted. The current 5GS cannot support PDU set processing of these encrypted service data streams, cannot correctly identify and mark the PDU set information of encrypted data streams, and cannot implement QoS processing and congestion control functions based on PDU set level.

[0282] How the 5GS system can support QoS control and PDU Set identification for end-to-end encrypted XR data streams is the problem that this invention aims to solve.

For example, the PDU set information can be sent along with the service data stream, while the QoS rules can be obtained from the UPF network element's server before the service data stream is sent.

[0391] In some embodiments, processing based on PDU set may involve discarding some PDUs or prioritizing the processing of PDUs.

[0392] In some embodiments, the AMF network element can send an N2 message to the (R)AN, and send encryption indication information, PDU set information and QoS rules to the RAN network element through the N2 message.

[0399] In step S2115, the AMF network element sends N2 SM information to the SMF.

[0400] In some embodiments, the AMF forwards the N2 SM information received from the (R)AN network element to the SMF network element through the PDU Session UpdateSM Context Request (Nsmf_PDU Session_UpdateSM Context Request) service operation.

[0401] In step S2116, the SMF network element sends a fifth response message to the AMF network element.

[0635] Figure 9A This is a flowchart illustrating an information processing method according to an embodiment of the present disclosure, such as... Figure 9A As shown, the embodiments of this disclosure relate to an information processing method, which includes:

[0636] Step S9101: Send the first message.

[0637] The AF sends an AF session resource request, which is the first message sent by the AF, for example, by creating an AF request through `Nnef_AF sessionWith QoS_Create request`. The AF carries the QoS requirements for XRM services and interactive media service data streams in the request message. The AF sends encryption indication information (which includes at least one of the following: whether to encrypt PDU / SDF, whether to support PDU set processing of encrypted PDU / SDF, whether to use a fully encrypted header or a partially encrypted header, whether to support an encryption proxy, whether to use E2E encryption, whether to prioritize PDU set processing of encrypted PDUs, and a description of the encryption protocol) to the 5GC (NEF / PCF). The AF can provide encryption indication information to the NEF / PCF during the AF QoS request / update process.

[0638] Optionally, it carries XRM service information, identifying the XRM service data flow or data flow group (e.g., multimodal transport ID), UE address / UE identifier, AF identifier application ID, process description, DNN, S-NSSAI, QoS parameters, and other relevant information. Here, the multimodal transport ID can be used to identify all processes in the XRM service group.

[0639] Step S9102, Authorization and Authentication.

[0640] If the NEF authorizes an AF request, it sends the AF request to the PCF via the NEF. (Optionally, the NEF performs relevant mappings, including mapping the XRM service identifier (AF service identifier) ​​to the DNN and S-NSSAI, mapping the external application to the CN application identifier; and mapping the external UE identifier to the CN UE identifier (such as SUPI) based on UDM subscription information, as well as mapping the external to internal XRM service group identifier based on UDM subscription information).

[0641] The NEF authorizes the AF request and, based on the parameters provided by the AF, decides whether to invoke the TSCTSF or directly contact the PCF (these signaling steps are the same as those for setting up an AF session with the required QoS procedures in Clause 4.15.6.6 of TS23.502). The PCF receives the attributes provided by the AF from either the NEF or the TSCTSF.

[0642] Step S9103: Receive the first information.

[0643] The 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 carries encryption indication information for the corresponding SDF (including at least one of the following: whether to encrypt PDU / SDF, whether to support PDU set processing of encrypted PDU / SDF, whether to use a fully encrypted header or a partially encrypted header, whether to support encrypted proxy, whether to use E2E encryption, whether to prioritize PDU set processing of encrypted PDUs, and a description of the encryption protocol).

[0644] Step S9104: Make a decision.

[0645] The PCF makes policy decisions. The PCF may determine that updated or new policy information needs to be sent to the SMF. The PCF considers the encryption indication information provided by the AF to determine the PCC rules (including at least one of the following: whether to encrypt PDUs / SDFs, whether to support PDU set processing of encrypted PDUs / SDFs, whether to use fully encrypted headers or partially encrypted headers, whether to support encrypted proxies, whether to use E2E encryption, whether to prioritize PDU set processing of encrypted PDUs, and a description of the encryption protocol).

[0646] The PCF sends the encrypted instruction information received from the AF / NEF to the SMF through the PCC rule, that is, it is issued to the SMF in the PCC rule.

[0647] PCF responds to NEF with the Npcf_Policy Authorization_Create response.

[0648] NEF sends an Nnef_AFsessionWithQoS_Create response message to AF, carrying the result and indicating whether the request has been authorized.

[0649] Step S9105: Send PCC rules.

[0650] The PCF initiates an SM policy association modification request and sends the PCC rule to the SMF.

[0651] Upon receiving the PCC rule, the SMF determines the QoS rule and QoS setting parameters, considers encryption indication information, and configures / activates the rule to the UPF (e.g., via an N4 session) (including at least one of the following: whether to encrypt PDU / SDF, whether to support PDU set processing of encrypted PDU / SDF, whether to use a fully encrypted header or a partially encrypted header, whether to support an encryption proxy, whether to use E2E encryption, whether to prioritize PDU set processing of encrypted PDUs, and a description of the encryption protocol).

[0652] SMF responds to PCF with a SM policy association modification response.

[0653] SMF initiates an N4 session modification request (encrypted instruction information) to UPF.

[0654] Step S9106: Send encryption instruction information.

[0655] UPF(s) responds to SMF.

[0656] UPF identifies and determines the PDU set information to be sent to NG-RAN based on the encryption indication information (e.g., in the extension header, GTP-U header), taking into account the encryption indication information (including at least one of the following: whether to encrypt PDU / SDF, whether to support PDU set processing of encrypted PDU / SDF, whether to use a fully encrypted header or a partially encrypted header, whether to support encryption proxy, whether to use E2E encryption, whether to prioritize PDU set processing of encrypted PDUs, and encryption protocol description).

[0657] In addition, the UPF sends encrypted instruction information to the NG-RAN (e.g., in the extended header, the GTP-U header).

[0658] For modifications to the SMF request, the SMF calls Namf_Communication_N1N2MessageTransfer([N2SM information](PDU Session ID,QFI,QoS Profile), N1 SM container)).

[0659] MF can send N2([N2 SM information received from SMF], NAS message(PDU session ID, N1 SM container(PDU session modification command))) message to (R)AN.

[0660] (R)AN can acknowledge an N2 PDU session request by sending an N2 PDU session Ack message to the AMF.

[0661] AMF forwards the N2 SM information received from AN to SMF through the Nsmf_PDUSession_UpdateSMContext service operation.

[0662] SMF responds using the Nsmf_PDUSession_UpdateSMContext response.

[0663] 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.

[0664] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0665] Figure 9B This is a flowchart illustrating an information processing method according to an embodiment of the present disclosure, such as... Figure 9B As shown, the embodiments of this disclosure relate to an information processing method, which includes:

[0666] 1a, Execution Figure 9A The steps in the process.

[0667] 1b, the AF can send information (QoS parameters and frame identifier parameters for each PDU in the QoS Flow) to the PCF via the Nnef_AFsessionWithQoS_Create request. The AF can also provide this information to the 5GS before the PDU session is established.

[0668] Step S9201: Send encryption instruction information.

[0669] AF sends encryption indication information to 5GC (NEF / PCF) (including at least one of the following: whether to encrypt PDU / SDF, whether to support PDU set processing of encrypted PDU / SDF, whether to use a fully encrypted header or a partially encrypted header, whether to support encryption proxy, whether to use E2E encryption, whether to prioritize PDU set processing of encrypted PDUs, and a description of the encryption protocol).

[0670] AF can provide encrypted indication information to NEF / PCF during AF QoS request / update process.

[0671] This includes protocol descriptions and auxiliary information related to PDU sets. The auxiliary information related to PDU sets may include QoS parameters for each PDU set in the QoS flow.

[0672] PDU Set Processing Instructions (indicating whether PDU Set-based processing should be activated in the workflow). These can be implicitly indicated through other PDU Set-related information provided by AF.

[0673] Whether all PDUs are needed by using the PDU Set at the application layer;

[0674] PDU Delay Budget

[0675] PDU error rate settings.

[0676] Step S9202: Determine the PCC rules.

[0677] The PCF generates appropriate PCC rules, which may include QoS parameters related to the PDU Set (as shown below). The PCF then sends the PCC rules to the SMF.

[0678] PCF determines PCC rules based on the encryption indication information provided by AF (the encryption indication information includes at least one of the following: whether to encrypt PDU / SDF, whether to support PDU set processing of encrypted PDU / SDF, whether to use a fully encrypted header or a partially encrypted header, whether to support an encryption proxy, whether to use E2E encryption, whether to prioritize PDU set processing of encrypted PDUs, and a description of the encryption protocol).

[0679] Step S9203: Send PCC rules.

[0680] The PCF sends the encrypted instruction information received from the AF / NEF to the SMF via the PCC rule.

[0681] Among them, the QoS parameters related to PDU settings are new QoS parameters for QoS processing based on PDU sets in 5GS, and may also include:

[0682] PDU Set Delay Budget (PSDB);

[0683] PDU set error rate (PSER)

[0684] Whether all PDUs are needed by using the PDU Set at the application layer;

[0685] Should the PDU Set be discarded when the PSDB exceeds the limit?

[0686] If this step is triggered by step 1b, the PCF will generate PCC rules based on the information provided by the AF.

[0687] Step S9204: Determine the QoS rules and QoS setting parameters.

[0688] The SMF generates a QoS profile and N4 rules based on the PCC rules provided by the PCF. The SMF sends the N4 rules to the UPF and the QoS profile to the RAN node via the AMF. Upon receiving the PCC rules, the SMF determines the QoS rules and QoS setting parameters, considering encrypted indication information, and configures / activates the rules to the UPF (e.g., via the N4 session). Upon receiving the PCC rules, the SMF forwards the PSI indication to the UPF (e.g., via the N4 session). Protocol descriptions and PDU set-related auxiliary information are sent to the SMF as part of the PCC rules. The SMF then sends these as part of the QoS profile to the NG-RAN via the AMF.

[0689] Step S9205: Determine PDU Set information.

[0690] UPF identifies relevant information (as shown below) based on the received N4 rules or the UPF's local configuration, and performs QoS processing based on PDU Set according to the N4 rule instructions. UPF identifies PDUs belonging to a PDU Set, and the information for each PDU Set is as follows:

[0691] Upon receiving the PCC rule, the SMF determines the QoS rule and QoS setting parameters, considers the encryption indication information, and configures / activates the rule to the UPF (e.g., via an N4 session). (The encryption indication information includes at least one of the following: whether to encrypt PDU / SDF, whether to support PDU set processing of encrypted PDU / SDF, whether to use a fully encrypted header or a partially encrypted header, whether to support an encryption proxy, whether to use E2E encryption, whether to prioritize PDU set processing of encrypted PDUs, and a description of the encryption protocol.)

[0692] In addition, the UPF sends encryption indication information to the NG-RAN (e.g., in the GTP-U header within the extended header). Alternatively, the (UP) encryption indication information is provided to the UPF from the AS (directly or via the NEF). Based on the encryption indication information, the UPF identifies and determines the PDU set information to be sent to the NG-RAN in the extended header (e.g., the GTP-U header). The UPF then sends the encryption indication information to the NG-RAN in the extended header (e.g., the GTP-U header). Alternatively, (UPF configuration). Based on the OAM configuration or operator policy, the UPF identifies and determines the PDU set information to be sent to the NG-RAN in the extended header (e.g., the GTP-U header) based on the encryption indication information. The UPF then sends the encryption indication information to the NG-RAN in the extended header (e.g., the GTP-U header).

[0693] Including parameters:

[0694] —PDU Set sequence number (QoS Flow is identified by QoS Flow ID, and each PDU Set in a QoS Flow is identified by PDU Set SN). Each QoS Flow can be used to send one or more PDU Sets.

[0695] The start / end PDU of the PDU set;

[0696] The serial number of the PDU in the PDU Set;

[0697] PDU size;

[0698] The importance of PDU settings;

[0699] PDU Set size;

[0700] The data burst has ended.

[0701] UPF identifies relevant information through the following methods / mechanisms:

[0702] Option 1: By matching the RTP / SRTP header and payload;

[0703] Option 2: New RTP extension header;

[0704] Option 3: Information provided by the autonomous system in the N6 package header, such as GTP-U;

[0705] Option 4: Detection based on traffic characteristics;

[0706] Option 5: Implement UPF through a non-standardized mechanism.

[0707] Step S9206: Send PDU Set information.

[0708] The UPF sends the PDU Set information to the RAN. The UPF then sends the relevant information for the PDU Set.

[0709] The RAN performs QoS processing based on the PDU Set information received in Step 6.
