[0003] This disclosure belongs to the field of wireless communication technology, specifically relating to a data transmission method, apparatus, communication device, and readable storage medium. Background Technology

[0004] In related technologies, a set of priority-based alternative Quality of Service (QoS) profiles is provided to Radio Access Network (RAN) nodes. Each QoS profile contains QoS parameters for different QoS levels. Based on radio resource availability, when current QoS requirements cannot be met, the RAN node can adjust the QoS level according to the configuration of the alternative QoS profile. However, in this scenario, dynamic changes on the service side, such as unexpected data, can make it difficult to adapt to service changes by adjusting different QoS levels, resulting in ineffective service adaptation.

[0365] Figure 1 shows a block diagram of a wireless communication system applicable to embodiments of the present disclosure. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can be a mobile phone, tablet computer, laptop computer, notebook computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR), virtual reality (VR) device, robot, wearable device, flight vehicle, vehicle user equipment (VUE), shipboard equipment, pedestrian user equipment (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among these, in-vehicle devices can also be referred to as in-vehicle terminals, in-vehicle controllers, in-vehicle modules, in-vehicle components, in-vehicle chips, or in-vehicle units, etc. It should be noted that the specific type of terminal 11 is not limited in the embodiments disclosed herein.

The base station is not limited to specific technical terms. Core network equipment may include, but is not limited to, at least one of the following: core network node, core network function, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Binding Support Function (BSF), etc.

[0367] Optionally, the solutions in this disclosure can be geared towards Extended Reality (XR) services. XR services can include multimodal data such as audio, video, and haptic feedback. In multi-form terminal device data stream transmission scenarios, these different modal data can be transmitted in multiple service streams and mapped into multiple QoS streams.

[0368] To address the issue of ineffective adaptation to services (such as XR services) in related technologies, this disclosure proposes extending the existing Alternative QoS scheme to the Alternative Protocol Data Unit Set (PDU Set) QoS scheme, i.e., extending it to the PDU Set granularity. For each QoS flow, AF provides a set of parameters for the Alternative PDU Set QoS Profile(s) (template or pattern) or the index or reference corresponding to the PDU Set QoS Profile(s).

[0369] Optionally, the Alternative PDU Set QoS can be extended to the PDU Set granularity. The AF can provide the correspondence between Protocol Data Unit Set Importance (PSI) and Alternative PDU Set QoS parameters, with one PSI corresponding to one level of PDU Set QoS parameters. When the PCF formulates policies (such as PCC rules), it formulates policies based on the one-to-one correspondence between the PDU Set QoS parameters and PSIs for each level, and sends the formulated / generated policies to the SMF. The SMF generates multi-level PDU Set QoS profiles based on the received policies and sends them to the RAN nodes. The RAN nodes can adjust the PDU Set QoS levels for different PDU Sets based on the PSI indication in the header sent by the UPF, such as adjusting or deciding on one or more parameters in the Alternative PDU Set QoS profile for each PDU Set.

[0370] Optionally, the Alternative PDU Set QoS can be extended to the PDU Set granularity. The AF can provide the correspondence between PDU Set Importance (PSI) and Alternative PDU Set QoS parameters. Each PSI can correspond to multiple levels of PDU Set QoS parameters. The RAN can adjust the PDU Set QoS at multiple levels according to the PSI indication, such as adjusting or deciding one or more parameters in the Alternative PDU Set QoS profile for each PDU Set.

[0371] Optionally, the AF can provide protocol description information to the UPF, which includes burst indications, such as the start or end information of a data burst (e.g., PDU Set start indication). The UPF can place this protocol description in the message header (e.g., GTP-U header) and provide it to the RAN node. The RAN node adjusts the PDU Set QoS or QoS level according to the burst indication; or, based on the received PSI, adjusts the QoS of certain PSIs separately.

[0372] In this embodiment of the disclosure, it is considered that the service side (such as XR service) supports the Alternative PDU Set QoS mechanism, and also supports dynamic adjustment of QoS level. The triggering conditions for adjusting the QoS level can be in the following ways:

[0373] (1) Based on business-side AF indication:

[0374] - User Plane: A QoS level adjustment indication is added to the data packet header. For example, if the AF needs to adjust the PDU Set QoS level based on service requirements, it will carry an indication to adjust the PDU Set QoS level (e.g., specifying the PDU Set QoS level number in the IP packet header, or the start or end identifier of the data burst). The UPF identifies the PDU Set information and data burst information, and sends the corresponding information to the RAN in the GTP-U header to adjust the QoS level. GTP-U refers to the General Packet Radio Service (GPRS) User Plane Tunneling Protocol.

[0375] (2) Based on the wireless resource situation on the network side: According to the existing Alternative QoS mechanism, when the network resources are insufficient to meet the PDU Set QoS requirements, the QoS level is downgraded; or when the resources are sufficient to meet the requirements again, the QoS level is upgraded.

[0376] (3) Pre-configured trigger conditions, such as those provided by AF:

[0377] - Based on traffic characteristics: Based on the periodicity of services and the burstiness of data, for example, after receiving a data burst size indication, it is determined whether the threshold has been exceeded; the RAN can reduce the QoS level (the action is to adjust to the specified level), and then trigger an upgrade when the next data burst indication arrives.

[0378] - Based on time characteristics: For example, based on the time distribution characteristics of services, the QoS level can be adjusted within certain time periods without allocating more resources, which is beneficial for network or equipment energy saving; for example, for video-on-demand services, the initial buffering bandwidth required after clicking the playback request is large, and the QoS requirement is high, and the QoS level can be reduced subsequently; or after dragging the progress bar, the bandwidth requirement is large at the beginning, and the QoS level can be reduced subsequently, such as setting two levels for adjustment.

[0379] Optionally, for the Alternative PDU Set processing mechanism, the PCF can provide the Alternative PDU Set QoS parameter information to the SMF in the PCC Rule according to the corresponding parameters of the Alternative PDU Set QoS provided by the AF; the Alternative PDU Set QoS Profile(s) generated by the SMF can carry parameters with different priorities for the PDU Set QoS or the index / level (reference) corresponding to these parameters.

[0380] Optionally, the SMF can instruct the RAN to adjust the PDU Set QoS index / level:

[0381] 1) Based on the Protocol description provided by AF, a new data burst start or end identifier is added to the Protocol description. SMF can provide this identifier / indication to UPF. When UPF sends downlink messages, it identifies the corresponding data burst information and puts it together with PDU Set information in the GTP-U header and provides it to RAN. RAN then adjusts the PDU Set QoS level accordingly.

[0382] 2) Based on the QoS level adjustment indications and triggering conditions provided by AF (such as the end of data burst, PDU Set importance indication, data burst size, etc.), SMF provides the triggering conditions for level changes to RAN in Alternative PDU Set QoS Profile(s). After the RAN detects the corresponding triggering conditions, it decides to dynamically adjust the PDU Set QoS level.

[0383] Optionally, if there is no adjustment instruction as described above, the RAN may reduce the QoS level in accordance with the traditional Alternative QoS adjustment method when the current QoS objective cannot be met (such as insufficient radio resources).

[0384] Optionally, for the exposure of QoS level-related network information, if the AF requests the PCF to report QoS satisfaction status, the PCF can configure a QoS notification control mechanism to support the reporting of whether the Alternative PDU Set QoS is satisfied and QoS level changes in the corresponding PCC rule, and provide the SMF with a corresponding Policy Control Request Trigger, as follows:

[0385] - Control plane: When the QoS level of the PDU Set changes on the RAN side, the RAN will notify the SMF of the corresponding change; the SMF can further notify the PCF; the PCF provides the AF with the corresponding PDU Set QoS reference, or provides the level corresponding to the AF's previous Alternative PDU Set QoS parameter set;

[0386] - User plane: Consider reporting QoS index / level and other information based on the user plane, and then the UPF provides it to the AF.

[0387] Optionally, AF can adjust the service code rate based on changes in the PDU Set QoS level to better correspond with the QoS level that the RAN side can currently meet, thereby achieving network-service collaboration.

[0388] In this embodiment of the disclosure, the alternative can be represented / understood as: Alternative.

[0389] A template or pattern can be represented / understood as: profile or profile(s).

[0390] A QoS template or pattern can be represented / understood as: QoS profile or QoS profile(s).

[0391] A PDU Set QoS template or pattern can be represented / understood as: PDU Set QoS profile or PDU Set QoS profile(s).

[0392] An index or hierarchy can be represented / understood as a reference.

[0393] The available PDU Set QoS templates or patterns can be represented / understood as: Alternative PDU Set QoS profile(s).

[0394] The available QoS templates or patterns can be represented / understood as: Alternative QoS profile(s).

[0395] Optionally, the business information in this disclosure embodiment may include, but is not limited to, at least one of the following: PDU Set information; business characteristics; media type; media characteristics; traffic information, etc.

[0396] The data transmission method, apparatus, communication device, and readable storage medium provided in this disclosure will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0397] Please refer to Figure 2, which is a flowchart of a data transmission method provided in an embodiment of this disclosure. The method is applied to a first device, which may be a RAN node or other device with similar functions. As shown in Figure 2, the method includes the following steps:

[0398] Step 21: The first device receives the first information sent by the first network function;

[0399] Step 22: The first device performs the first operation based on the first information.

[0400] In this embodiment of the disclosure, the first network function may be SMF or other network functions with similar functionality. The first information may include information for a single QoS flow or multiple QoS flows.

[0401] Optionally, the first operation may include, but is not limited to, at least one of the following:

[0402] For each PDU Set, adjust or decide (e.g., determine) the available PDU Set QoS templates or patterns, i.e., adjust or decide the Alternative PDU Set QoS profile(s);

[0403] For each PDU Set, adjust or decide one or more parameters in the available PDU Set QoS templates or patterns, i.e., adjust or decide one or more parameters in the Alternative PDU Set QoS profile(s);

[0404] For each QoS flow, adjust or decide on the available PDU Set QoS template or mode;

[0405] For each QoS flow, adjust or decide on one or more parameters from the available PDU Set QoS templates or patterns;

[0406] For one or more QoS flows, adjust or decide on the available QoS parameters or parameter sets related to service information;

[0407] For one or more QoS flows, adjust or decide on the index or level corresponding to the available QoS parameters or parameter sets related to service information.

[0408] It should be noted that when adjusting or deciding on available QoS parameters or parameter sets related to service information for one or more QoS flows, the QoS parameter adjustment for each QoS flow can be based on the SMF configuration provided to the RAN, selecting appropriate QoS parameters or QoS parameters related to service information. RAN adjustments are primarily based on radio resource information and can refer to service information provided by the user plane. In this embodiment, the AF can provide available QoS parameters related to service information, and simultaneously provide service information. When the network performs QoS flow mapping and QoS parameter configuration for service flows according to the AF request, the parameter configuration provided to the RAN is fixed.

[0409] Optionally, the business information includes at least one of the following: PDU Set information, business characteristics, media type, media characteristics, traffic information, etc.

[0410] Optionally, the first information may include, but is not limited to, at least one of the following:

[0411] One or more selectable PDU Set QoS templates or patterns, i.e., one or more Alternative PDU Set QoS profile(s);

[0412] The available PDU Set QoS templates or modes have a one-to-one correspondence with the Protocol Data Unit Set Importance (PSI), i.e., one PSI corresponds to one Alternative PDU Set QoS profile(s); this correspondence can also be expressed as: a one-to-one correspondence between the index or reference corresponding to the Alternative PDU Set QoS profile(s) and the PSI.

[0413] The correspondence between multiple selectable PDU Set QoS templates or patterns and a single PSI, i.e., one PSI corresponds to multiple Alternative PDU Set QoS profile(s); this correspondence can also be expressed as: the correspondence between the index or reference corresponding to multiple Alternative PDU Set QoS profile(s) and a single PSI.

[0414] One or more selectable QoS parameters or parameter sets related to PDU Set service information;

[0415] Indexes or levels corresponding to available QoS parameters or parameter sets related to business information;

[0416] The correspondence between available QoS parameters or parameter sets and service information;

[0417] The correspondence between available QoS parameters or parameter sets related to service information and the service information itself;

[0418] The mapping relationship between the index or level of the available QoS parameters or parameter sets related to service information and the service information.

[0419] The first instruction is used to instruct the first device to adjust or decide on at least one of the following: PDU Set QoS template or mode, selectable QoS template or mode, and one or more parameters in the selectable PDU Set QoS template or mode;

[0420] The adjustment or decision result reporting instruction can be used to instruct the first device (such as a RAN node) to report information, such as reporting a parameter that cannot be satisfied in the current QoS profile, and / or the index or level corresponding to the adjusted Alternative QoS profile; for PDU Set QoS, it can also instruct to report a parameter that cannot be satisfied in the current PDU Set QoS profile, and / or the index or level corresponding to the adjusted PDU Set QoS profile.

[0421] In some embodiments, the first information sent by the SMF to the RAN node may include at least one of the following: one or more selectable PDU Set QoS templates or patterns; a one-to-one correspondence between the selectable PDU Set QoS templates or patterns and PSIs; a correspondence between multiple selectable PDU Set QoS templates or patterns and a single PSI; a first indication; and an indication to report adjustment or decision results. In this case, the RAN node may perform adjustments at the PDU Set granularity based on the first information, such as adjusting or deciding on the Alternative PDU Set QoS profile(s) for each PDU Set; or adjusting or deciding on one or more parameters in the Alternative PDU Set QoS profile(s) for each PDU Set.

[0422] In other embodiments, the first information sent by the SMF to the RAN node may include at least one of the following: one or more selectable PDU Set QoS templates or patterns; a first indication; an indication to report adjustment or decision results; in this case, the RAN node may perform QoS flow granularity adjustments based on the first information, such as: adjusting or deciding on the Alternative PDU Set QoS profile(s) for each QoS flow; or adjusting or deciding on one or more parameters in the Alternative PDU Set QoS profile(s) for each QoS flow.

[0423] Understandably, the solutions in this disclosure can achieve QoS level adjustment at the PDU Set granularity or QoS flow granularity, thereby effectively adapting to services. For example, when targeting XR services, it can effectively adapt to the highly dynamic changes on the XR service side, supporting the network side to dynamically adjust different QoS levels to flexibly adapt to service change requirements.

[0424] Optionally, performing the first operation described above may include:

[0425] The first device performs the first operation based on the first information, depending on at least one of the following changes:

[0426] Wireless resource information;

[0427] Wireless channel information;

[0428] Business information, including but not limited to PDU Set information, business characteristics, media type, media characteristics, traffic information, data packet changes, etc.

[0429] In other words, the first device (such as a RAN node) can adjust QoS based on changes in radio resources or radio channel status, according to the first information (such as configuration information provided by the core network to the RAN).

[0430] In this way, QoS level adjustments at the PDU Set granularity or QoS stream granularity can be performed based on changes in wireless resources and / or wireless channel status, enabling multi-level QoS guarantees.

[0431] Optionally, the parameters in the selectable PDU Set QoS template or mode may include, but are not limited to, at least one of the following:

[0432] PDU Set Delay Budget (PSDB);

[0433] PDU Set Error Rate (PSER);

[0434] PDU Set Integrated Handling Information (PSIHI).

[0435] Optionally, the data transmission method in this disclosure embodiment may further include:

[0436] If a first condition is met, the first device sends a first notification message to the first network function; the first condition includes at least one of the following:

[0437] Wireless resources cannot meet the demand or meet the demand again;

[0438] The first device determines that the parameter in the PDU Set QoS template or mode cannot be satisfied or is satisfied again; for example, this parameter can be PSDB or PSER, etc., and the corresponding condition is: the first device determines that the PSDB or PSER in the PDU Set QoS profile cannot be satisfied or is satisfied again.

[0439] The lowest priority among the available PDU Set QoS templates or patterns cannot be satisfied, i.e., the lowest priority in the Alternative PDU Set QoS profile(s) cannot be satisfied;

[0440] QoS parameters or parameter sets related to service information cannot be satisfied or are satisfied again; in this case, QoS parameters related to service information may include PSDB parameters and / or PSER parameters, which cannot be satisfied or are satisfied again.

[0441] The lowest priority among the available QoS parameters or parameter sets related to the service information cannot be satisfied.

[0442] Optionally, the first notification information may be used to notify at least one of the following:

[0443] The parameter in the PDU Set QoS template or mode is either not satisfied or is satisfied again; for example, this parameter could be PSDB or PSER, etc.

[0444] The index or level corresponding to the available alternative PDU Set QoS templates or modes that can be satisfied; for example, this index or level could be: the reference corresponding to the currently satisfying Alternative PDU Set QoS profile(s);

[0445] The index or level corresponding to the lowest priority in the available PDU Set QoS templates or modes cannot be satisfied;

[0446] QoS parameters or parameter sets related to service information cannot be satisfied or need to be satisfied again;

[0447] The index or level corresponding to the available QoS parameters or parameter sets related to the business information that can be satisfied;

[0448] The available QoS parameters related to the business information, or the index or level corresponding to the lowest priority in the parameter set, cannot be satisfied.

[0449] Optionally, performing the first operation described above may include:

[0450] The first device performs the first operation based on the first information and the service information received from the fourth network function.

[0451] For example, the service information may be PDU Set information. Alternatively, the service information may be the PSI information of each PDU Set in the header of a received data packet (such as the GTP-U header), or the service information in the header of a received data packet. For instance, appropriate Alternative QoS parameters related to the service information can be selected based on the service-related information; during the duration of a service flow's transmission in the network, the QoS parameters or PDU Set QoS parameters are relatively fixed and do not dynamically change over time.

[0452] Optionally, the PSI information can be the PSI of an I / P / B frame or information about the start frame of a Group of Pictures (GOP), etc., and there are no restrictions on this.

[0453] Optionally, the data transmission method in this disclosure embodiment may further include:

[0454] The first device reports second information, which includes, but is not limited to, at least one of the following:

[0455] Parameters in a QoS template or pattern; for example, this parameter can be a parameter in the currently achievable QoS profile(s) or a parameter in the adjusted QoS profile(s);

[0456] Parameters in the PDU Set QoS template or pattern; for example, this parameter can be a parameter in the currently satiable PDU Set QoS profile(s) or a parameter in the adjusted PDU Set QoS profile(s);

[0457] The index or level corresponding to the available QoS templates or modes; for example, this index or level can be the index or level corresponding to the currently available Alternative QoS profile(s), or the index or level corresponding to the adjusted Alternative QoS profile(s);

[0458] The index or level corresponding to the available PDU Set QoS template or mode; for example, this index or level can be the index or level corresponding to the currently available Alternative PDU Set QoS profile(s), or the index or level corresponding to the adjusted Alternative PDU Set QoS profile(s);

[0459] The index or level corresponding to the available QoS parameters or parameter sets;

[0460] The index or level corresponding to the available QoS parameters or parameter sets related to business information.

[0461] In this way, by using the reported information, the receiver can obtain information related to the QoS profile(s), which facilitates subsequent data transmission.

[0462] Optionally, the first device (such as a RAN node) can send the second information to the Application Function (AF) or Application Server (AS) via the UPF. This allows the service side to provide QoS level adjustment instructions based on service requirements, while the network side can also expose its adjusted QoS level to the service side, enabling flexible network-service collaboration. This facilitates more precise resource scheduling by the network side based on service characteristics, improving RAN resource utilization efficiency.

[0463] Please refer to Figure 3, which is a flowchart of a data transmission method provided in an embodiment of this disclosure. This method is applied to a second network function, which may be PCF or other network functions with similar functionality. As shown in Figure 3, the method includes the following steps:

[0464] Step 31: The second network function receives the third information sent by the second device;

[0465] Step 32: The second network function generates first strategy information based on the third information.

[0466] In this embodiment of the disclosure, the second device may be an AF or other device with similar functions.

[0467] Optionally, the third information includes, but is not limited to, at least one of the following:

[0468] One or more selectable PDU Set QoS templates or patterns, i.e., one or more Alternative PDU Set QoS profile(s);

[0469] An index or level corresponding to one or more selectable PDU Set QoS templates or patterns, i.e., a reference corresponding to one or more Alternative PDU Set QoS profile(s);

[0470] The available PDU Set QoS templates or modes have a one-to-one correspondence with PSIs, meaning that one PSI corresponds to one Alternative PDU Set QoS profile(s). This correspondence can also be expressed as a one-to-one correspondence between the index or reference corresponding to the Alternative PDU Set QoS profile(s) and the PSI.

[0471] The correspondence between multiple selectable PDU Set QoS templates or patterns and a single PSI, i.e., one PSI corresponds to multiple Alternative PDU Set QoS profile(s); this correspondence can also be expressed as: the correspondence between the index or reference corresponding to multiple Alternative PDU Set QoS profile(s) and a single PSI.

[0472] The adjustment or decision result reporting instruction can be used to instruct the first device (such as a RAN node) to report information, such as reporting a parameter that cannot be satisfied in the current QoS profile, and / or the reference corresponding to the adjusted Alternative QoS profile; for PDU Set QoS, it can also instruct to report a parameter that cannot be satisfied in the current PDU Set QoS profile, and / or the reference corresponding to the adjusted PDU Set QoS profile;

[0473] Available QoS parameters or parameter sets related to business information;

[0474] Indexes or levels corresponding to available QoS parameters or parameter sets related to business information;

[0475] Service information; optionally, this service information may include media type, traffic characteristics, etc. For example, AF can provide mapping between different media types and QoS parameters, that is, for each type of service, a matching QoS parameter or alternative QoS parameter is given, or a QoS parameter related to PDU Set and an alternative QoS parameter related to PDU Set can be given.

[0476] The correspondence between available QoS parameters or parameter sets and service information;

[0477] The correspondence between available QoS parameters or parameter sets related to service information and the service information itself;

[0478] The index or level corresponding to the available QoS parameters or parameter sets related to the service information and their correspondence with the service information.

[0749] The present disclosure will now be described in conjunction with specific embodiments.

[0750] Example 1

[0751] In this first embodiment, the core network receives the Alternative PDU Set QoS information provided by the AF, formulates corresponding policies, and implements corresponding configurations. As shown in Figure 14, the specific data transmission process may include:

[0752] Step 1: The AF requests support for Alternative PDU Set QoS and sends third information to the NEF in the available Alternative Service Requirements. Optionally, the third information includes at least one of the following: one or more Alternative PDU Set QoS profile(s); a reference corresponding to one or more Alternative PDU Set QoS profile(s); a one-to-one correspondence between Alternative PDU Set QoS profile(s) and PSI; a correspondence between multiple Alternative PDU Set QoS profile(s) and a single PSI; an indication to report adjustment or decision results, etc.

[0753] Step 2: NEF forwards the third information to PCF.

[0754] Step 3: The PCF makes a decision based on the third information and generates first policy information, which may include at least one of the following: one or more Alternative PDU Set QoS profile(s); references corresponding to one or more Alternative PDU Set QoS profile(s); one-to-one correspondence between Alternative PDU Set QoS profile(s) and PSI; correspondence between multiple Alternative PDU Set QoS profile(s) and a single PSI; and instructions for reporting adjustment or decision results.

[0755] Step 4: PCF sends the first policy information to SMF.

[0756] Step 5: The SMF generates first information based on the first policy information and sends it to the RAN to instruct the RAN to dynamically adjust the PDU Set QoS level; wherein, the first information may include at least one of the following: one or more Alternative PDU Set QoS profile(s); a one-to-one correspondence between Alternative PDU Set QoS profile(s) and PSI; a correspondence between multiple Alternative PDU Set QoS profile(s) and a single PSI; an indication to report adjustment or decision results, etc.

[0757] Step 6: The SMF sends the policy to the UPF, indicating the protocol description information, as well as the PDU Set information identifier, data burst start or end information, etc.

[0758] Step 7: Based on the received first information, the RAN performs at least one of the following: for each PDU Set or each QoS flow, adjust or decide on the Alternative PDU Set QoS profile(s); for each PDU Set or each QoS flow, adjust or decide on the reference corresponding to the Alternative PDU Set QoS profile(s).

[0759] Example 2

[0760] In this second embodiment, the AF adjusts the PDU Set QoS level based on service conditions and via the user plane, following the data packet indication. As shown in Figure 15, the specific data transmission process includes:

[0761] Step 0: When AF requests support for Alternative PDU Set QoS, it also provides the corresponding protocol description information. The corresponding PCC Rule is set by PCF, and SMF provides the protocol description information to UPF. Optionally, a new field is added to the protocol description information, including a field indicating the start or end of the data burst (direct or indirect indication). The data burst size can also be used as start information.

[0762] Step 1: The SMF sends the Alternative PDU Set QoS profile to the RAN, instructing the RAN to adjust the PDU Set QoS level based on the user plane indication.

[0763] Step 2: UPF identifies and marks PDU Set information. When the IP packet header sent by AS contains data burst start or end information, UPF puts this information in the GTP-U header and sends it to RAN.

[0764] Step 3: The RAN dynamically adjusts the PDU Set QoS level based on the start or end information of the data burst identified by the user plane data identifier, according to the configuration of the Alternative PDU Set QoS profile.

[0765] Example 3

[0766] In this third embodiment, the RAN side autonomously adjusts the QoS level of the PDU Set based on pre-configuration and reports it to the AF. As shown in Figure 16A, the specific data transmission process includes:

[0767] Step 1: When AF requests support for Alternative PDU Set QoS, it sets the trigger conditions for QoS level adjustment (e.g., it may include start or end identifier information of data bursts); at the same time, it subscribes to notifications of whether the QoS target is met.

[0768] Step 2: The PCF sets the relevant PCC Rule based on the Alternative PDU Set QoS information, and simultaneously sets the adjustment or decision result reporting instruction, which is then provided to the SMF;

[0769] Step 3: The SMF sends the Alternative PDU Set QoS profile(s) to the RAN, instructing the RAN to adjust the PDU Set QoS level independently according to the triggering conditions; at the same time, it instructs the RAN to report the QoS level adjustment information.

[0770] Step 4: After the RAN adjusts the QoS level of the PDU Set, it notifies the AF of the adjusted level through the user plane;

[0771] Step 5: After receiving a data packet containing QoS index / level adjustments, the UPF exposes the QoS index or level information to the AF along with the data packet, or provides it to the AF through event exposure. If the UPF provides QoS parameters containing QoS parameters or PDU Set related QoS parameters to the AF or AS, the UPF can map the QoS index / level reported by the RAN to the corresponding QoS parameters according to the mapping information between QoS parameters and index / level provided by the SMF, thereby achieving reporting.

[0772] Example 4

[0773] In this fourth embodiment, the AF can provide third information, including alternative QoS parameters or parameter sets related to service information (such as PDU Set), and simultaneously provide service information to the network. Based on the service information and the correspondence between the service information and the alternative QoS parameters, the network maps the service flow to the QoS flow and provides the configuration of the alternative QoS parameters or parameter sets related to the service information for the QoS flow. After this configuration is provided to the RAN, the RAN can adjust the alternative QoS parameters or their corresponding levels according to changes in radio resources and in conjunction with the service information. The service information can be provided to the RAN through the user plane (identified by the UPF in the GTP-U header). The RAN's adjustment of the alternative QoS level may depend on the implementation. The service information in this fourth embodiment may include at least one of the following: PDU Set information, service characteristics, media type, media characteristics, traffic information, etc.

[0774] As shown in Figure 16B, the specific data transmission process includes:

[0775] Step 1: The AF initiates an AF session with required QoS requests, providing third-party information describing the alternative service requirements. This includes alternative QoS parameters or parameter sets related to service information (such as PDU Sets) and their corresponding indexes or levels, service information, and the correspondence between the alternative QoS parameters or parameter sets related to the service information and the service information itself. After NEF authentication, NEF provides the alternative service requirements to the PCF.

[0776] Step 2: Based on the information provided by AF, PCF generates an alternative QoS parameter set related to the service information (such as PDU Set) for the corresponding QoS flow, as well as the correspondence between the service information and the parameter set, and provides a mapping from service flow to QoS flow (the mapping from service flow to QoS flow can be mapped to one or more QoS flows according to the service information); generates the first policy information (PCC Rule) and sends the PCC Rule to SMF.

[0777] Step 3: The SMF generates the first information based on the PCC Rule, including the configuration of Alternative QoS parameters for each QoS flow and sends it to the RAN. This includes Alternative QoS parameters or parameter sets related to the service information (PDU Set) and their corresponding indexes or levels, as well as the correspondence between the Alternative QoS parameters or parameter sets related to the service information (such as PDU Set) and the service information. The SMF also provides the UPF with service flow identification information for the UPF to perform service information identification and data flow mapping.

[0778] Step 4: The UPF identifies the service information and can also identify the service information or PDU Set information in the GTP-U header of the data packet and send it to the RAN.

[0779] Step 5: Based on the configuration of the Alternative QoS parameters related to the service information and considering the radio resource situation, the RAN performs the first operation by selecting the appropriate level corresponding to the Alternative QoS parameter related to the service information (such as the PDU Set). The RAN's adjustment of QoS parameters depends on the implementation.

[0780] Specifically, the first operation can, for example, involve the RAN adjusting the level of the Alternative QoS parameter or the Alternative QoS parameter related to the PDU Set if the radio conditions do not meet the currently set QoS parameter requirements. When radio resources are sufficient, the QoS parameter level can be increased. Taking media type as an example, the SMF can provide the RAN with the mapping between media type and Alternative QoS parameters or Alternative QoS parameters related to the PDU Set. When the UPF provides the RAN with the media type indication in the GTP-U header of the data packet through the user plane, for example, providing video media type (Media type 1) or audio media type (Media type 2), the RAN can adjust the priority to the appropriate Alternative QoS parameter based on the indication of the video or audio media type (Media type 1 or Media type 2), according to the mapping configured in the control plane.

[0781] Other business information, such as PDU Set information, business characteristics, media characteristics, traffic information, and traffic characteristics, can be adjusted in accordance with the methods described in the above embodiments, and will not be repeated here.
