[0141] Application function (AF): also known as application controller, mainly used for transmitting application side requirements to network side, such as quality of service (QoS) requirements, user state event subscription, etc. The AF can be an application function entity of a third-party application, or an application service deployed by an operator, such as an IMS voice call service. Among them, when the application function entity of the third-party application interacts with the core network, it can be authorized by the network exposure function (NEF), for example, the application function entity of the third-party application directly sends a request message to the NEF, the NEF verifies whether the AF is allowed to send the request message, and if the verification is passed, the request message is forwarded to the corresponding policy control function (PCF) or unified data management function (UDM).

[0147] Unified data repository (UDR): mainly responsible for accessing functions of data types such as subscription information, policy data, and application data, and the UDR can be interconnected with UDM, PCF, NEF, etc. to realize access or calling of corresponding network elements.

[0148] Of course, other network functions in addition to the network functions illustrated in the above examples can also be included in the core network, which are not listed here.

[0149] It should be noted that the name of the corresponding network function for implementing each function in the embodiments of the present disclosure is not limited, and it can also implement other functions or be integrated with other function network elements, and can also be called other names.

[0150] In the 5G networking architecture shown in FIG. 1B, the main functions of some related communication interfaces between network functions and network functions, network functions and devices are as follows:

[0151] N1 interface: an interface between AMF and terminal for signaling plane, independent of access network, used for exchanging signaling messages between core network and terminal, which can be used in terminal registration, terminal PDU session establishment, network side terminal policy configuration and other processes. N2 interface: an interface between AMF and RAN device, used for transmitting radio bearer control information from core network to RAN device. N3 interface: an interface between (R)AN device and UPF, used for transmitting terminal service data between RAN device and UPF. N4 interface: an interface between SMF and UPF, used for transmitting information between control plane and user plane, which can be used in control plane terminal to complete network access operation according to the subscription information of the operator and other processes. N6 interface: an interface between UPF and data network (Data Network, DN), used for transmitting terminal service data between UPF and DN. N7 interface: an interface between PCF and SMF, used for transmitting PDU session granularity and service data flow granularity control policy information.

N10 interface: an interface between SMF and UDM, used for SMF to obtain session management related subscription information from UDM, and SMF to register terminal current session related information to UDM. N11 interface: an interface between SMF and AMF, used for transmitting PDU session tunnel information between RAN device and UPF, control message sent to terminal, and radio resource control information sent to RAN device.

[0152] Mobile media class services, XR (extended reality) services such as cloud AR (augmented reality) / VR (virtual reality), cloud gaming, video-based machine or drone remote control services, and the like are expected to contribute to an increasing amount of traffic for 5G networks. XR services also involve multi-modal data streams, which can be data input from the same device or different devices (including sensors) describing the same service or application, which can be output to one or more destination device terminals. The data streams in multi-modal data often have correlations, such as synchronization of audio and video streams, synchronization of haptics and vision, and the like. There are some common characteristics of the data streams of such media services, between the data streams, and the requirements of these service data streams for network transmission. Effective identification and utilization of these characteristics will be more helpful for network and service transmission, control, and also for service assurance and user experience.

[0153] XRM (XR and media) services require the 5th generation system (5GS) to comprehensively consider the quality of service (QoS) characteristics of related data streams of services, such as whether delay GBR (guaranteed bitrate) data streams, GFBR (guaranteed flow bit rate), PDB (packet delay budget), MDBV (maximum data burst volume), and the like can be simultaneously satisfied and consistently coordinated. The consistency of QoS authorization and execution of multiple XRM data streams involving one terminal and XRM data streams of multiple terminals is guaranteed.

[0154] In the 5G system, the function enhancement of AF processing of XRM service data streams based on each PDU set is supported. To support the QoS awareness and assurance enhancement of XRM service data streams by AF, and the Quality of Experience (QoE) enhancement of users. Including, AF provides PDU Set specific QoS characteristics and protocol description: -PDU Set Delay Budget (PSDB); -PDU Set Error Rate (PSER); -PDU Set Integrated Handling Information (PSIHI).

[0155] The SMF and UPF can perform general packet radio service tunnelling protocol for the user plane (GTP-U) extension header of the corresponding PDU in the corresponding SDF PDU set according to the protocol description and protocol header extension provided by the AF, and carry PDU Set information. The PDU Set information is used by the NG-RAN for PDU Set-based QoS processing. The PDU Set information includes: -PDU Set sequence number; -indication of the last PDU of the PDU Set; -PDU sequence number within the PDU Set; -PDU Set size (in bytes); -PDU Set importance, used to identify the relative importance compared to other PDU Sets in the QoS flow.

[0156] The above PDU set feature enhancement greatly improves the QoS guarantee of the 5GS for the XRM service / interactive service demand characteristics.

[0157] However, as a service data with strong periodicity characteristics, although the data transmission period of the XRM service can be relatively stable, the data size and transmission time in different periods are different, and the data transmission in the transmission period does not have obvious periodicity and determinacy. There is often a data burst transmission in the transmission period, and after the data burst transmission is completed, there is a long idle period without data transmission in the transmission period. For the data receiving end, it still needs to listen in the transmission period, which will occupy the communication resources, and there is unreasonable radio resource scheduling and resource waste. Therefore, how to support the radio resource management and optimization of the XRM service / interactive service, and better resource scheduling and configuration to more effectively guarantee the End to End (E2E) QoS demand is a problem to be solved.

[0158] Based on this, the embodiment of the disclosure provides a data transmission method and device.

[0361] In some embodiments, other optional implementations described before or after the description corresponding to FIG. 5 can be referred to.

[0362] To facilitate understanding of the embodiments of the present disclosure, exemplary embodiments are provided.

[0363] It can be understood that, as a service data with strong periodicity characteristics, the XRM service has a relatively stable data transmission period, but the data size and transmission time in the actual period are different, the data transmission in the transmission period does not have obvious periodicity and certainty, and there is often data burst transmission in the transmission period. After the data burst transmission ends, there is a long idle period without data transmission in the transmission period. For the data receiving end, it still needs to listen in the transmission period, which occupies communication resources, and there is unreasonable wireless resource scheduling and resource waste, which leads to the problem that how to support the wireless resource management and optimization of the XRM service / interactive service still needs to be solved by the communication system.

[0364] Therefore, how to more effectively support the wireless resource management and optimization of the XRM service / interactive service, better resource scheduling and configuration, more effectively guarantee the end-to-end QoS requirement, better adapt the resource requirement and allocation, and coordinate the E2E QoS resource are problems to be solved by the present disclosure.

[0365] The embodiments of the present disclosure propose a first marker of data burst, that is, time interval information from the completion of current data burst transmission to the start of the next data burst, which can also be called Time to Next Burst (TTNB) or inter-burst time. In the case that the sending end and the receiving end of the data burst transmission support the first function enabled to identify the first marker, the sending end can add the first marker in the data in the data burst transmission process, and the receiving end can identify the first marker to determine the TTNB, and then perform corresponding resource configuration and / or management according to the TTNB, which can support the wireless resource management and optimization of the XRM service / interactive service, better perform resource scheduling and configuration, and effectively guarantee the End to End (E2E) QoS requirement.

[0366] In addition, for multiple UPFs, some UPFs support the first function and some UPFs do not support the first function, in the embodiment of the present disclosure, the UPF supporting the first function is selected or reselected for marking the TTNB and indicating the access network device and the terminal to perform corresponding resource configuration and / or management according to the TTNB.

[0368] 1. The AF sends an AF session resource creation or update request, for example, through Nnef_AFsessionWithQoS_Create / update request, to create or update the AF session.

[0369] In some embodiments, for the AF, the AF provides the PCF with the next burst time (TTNB) marking indication and / or protocol description (through the NEF or directly) (see the fifth indication information in the above embodiment) to help identify the TTNB of the data burst.

[0370] Optionally, the AF can provide the protocol description for the PCF's uplink, downlink, uplink and downlink data burst TTNB marking.

[0371] In addition, the AF also provides the TTNB marking indication and / or protocol description (see the fifth indication information in the above embodiment) using the Nnef_AFsessionWithQoS_Create request message or the Nnef_AFsessionWithQoS_Update request message.

Here, the multi-modal service ID can be used to identify all flows in the XRM service group.

[0373] 2. The NEF authorizes the AF request. If it is an untrusted AF, the NEF sends the AF's request to the PCF via the NEF. (Optionally, the NEF performs relevant mapping, including mapping of the XRM service (AF-Service-Identifier) to Data Network Name (DNN) and Single Network Slice Selection Assistance information (S-NSSAI), mapping of external application to core network (CN) application identifier; and mapping of external UE identifier to CN internal UE identifier (such as SUPI) based on UDM subscription information, and mapping of external to internal XRM service group identifier based on UDM subscription information).

[0374] 3. The NEF authorizes the AF request and determines whether to invoke the Time Sensitive Communication and Time Synchronization Function (TSCTSF) or directly contact the PCF based on the parameters provided by the AF. The PCF receives the attributes provided by the AF from the NEF or TSCTSF. The NEF triggers a Npcf_PolicyAuthorization_Create request to send the AF request to the PCF, carrying the indication and QoS requirement information for PCF policy decision.

[0375] 4. The PCF makes a policy decision. The PCF can determine that it needs to send updated or new policy information to the SMF.

[0376] In some embodiments, for the PCF, the PCF determines / includes the TTNB marker indication of the SMF (e.g. in PCC rules) to request the UPF to identify and mark the TTNB of DL data burst, and / or to request the UE to identify and mark the TTNB of UL data burst.

[0377] Optionally, the AF or locally provisioned protocol description is included according to pre-configured operational policy (e.g. configured in PCF or SMF or UPF). Optionally, the next time to burst (TTNB) marker indication is authorized by the PCF to be sent to the SMF in PCC rules.

[0380] 7. PCF initiates SM Policy Association Modification Request to SMF.

[0381] Wherein, after receiving the PCC rule, the SMF determines the QoS rule and QoS set parameter to configure / activate the rule of the UPF (for example, through N4 session). Optionally, the SMF provides the next burst time (TTNB) marker indication to the UPF / (UPF and NG-RAN) / UE to indicate the time of the next burst time (TTNB) marker. Optionally, the SMF determines the uplink, downlink, uplink and downlink data burst arrival next burst time (TTNB) marker indication. Optionally, the SMF derives the QoS parameter of the QoS flow according to the PCC rule information of the PCC rule bound to this QoS flow.

[0382] 8. SMF replies to PCF with SM Policy Association Modification Response.

[0383] 9. SMF triggers PDU session modification procedure to provide the next burst time (TTNB) marker time indication to the UPF / (UPF and NG-RAN) / UE to indicate the time of the next burst time (TTNB) marker.

[0384] In some embodiments, for the UPF, the UPF performs the arrival next burst time (TTNB) marker according to the indication of the SMF (for example, identifies and marks the arrival next burst time carried in the N6 PDU EH of the DL data burst).

[0385] Optionally, the UPF sends the TTNB to the access network device (NG-RAN) through the GTP-U extension header (EH) of the DL data burst data packet.

[0386] In addition, the UPF sends the TTNB to the NG-RAN through the GTP-U EH of the last PDU of the DL data burst.

[0387] In addition, the UPF also includes the TTNB marker indication to the NG-RAN to indicate the support of the TTNB marker.

[0388] In some embodiments, for NG-RAN, NG-RAN implements resource implementation or management corresponding to the TTNB marking received through the GTP-U EH of the DL data burst PDU.

[0389] In some embodiments, for a terminal UE, the UE performs a next time to burst (TTNB) marking (e.g., identifying and marking the next time to burst carried in the PDU header of the UL data burst) according to the indication of the SMF.

[0390] Optionally, the next time to burst (TTNB) marking of the UL data burst can be used for UL resource management.

[0391] 9a. If the current UPF does not support TTNB Marking, the SMF triggers a PDU session modification procedure to perform a UPF reselection procedure supporting TTNB marking. Alternatively, or when the SMF initially selects a UPF, the SMF selects a UPF supporting TTNB Marking functionality, considering the instruction of the SMF and / or local configuration.

[0392] The UPF is discovered / selected / reselected by the UPF selection function in the SMF, considering the functionality related to TTNB marking.

[0393] The UPF selection function in the SMF can discover / select / reselect the UPF / UPF instance using the NRF. In this case, the SMF sends a request to the NRF to discover the UPF, and the functionality related to TTNB marking is provided in the request for UPF / UPF instance discovery / selection / reselection.

[0402] In a possible implementation, as shown in FIG. 6B, the SMF uses the NRF to preset the UPF instance instances.

[0403] This procedure is applicable when the SMF wants to be aware of the available UPFs in the network and supports a list of parameters.

[0404] The following will occur when the SMF wants to be notified of the available UPFs in the network:

[0405] 1. The SMF issues the Nnrf_NFManagement_NFStatusSubscribe service operation, providing the target UPF Provisioning Information that it is interested in.

[0414] The AMF / UDM / OAM / Original UPF can provide the TTNB marking indication to the SMF to indicate the functional requirement of TTNB marking. The TTNB marking indication or requirement is used for UPF / UPF instance discovery / selection / reselection.

[0415] 2. The NRF can provide a list of all UPFs that currently meet the SMF subscription through Nnrf_NFManagement_NFStatusNotify. This Nnrf_NFManagement_NFStatusNotify indicates a subset of the target UPF preset information supported by each UPF.

[0416] The UPF supports the following functions required by the SMF for UPF selection or reselection, which are issued to the SMF by the NRF:

[0417] - Support functions related to TTNB marking;

[0418] - Or, support functions related to TTNB marking, which are associated with high data rate low latency services, extended reality (XR), and interactive media services.
