[0031] Now, the exemplary embodiments will be described in a more comprehensive manner with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as being limited to these examples; on the contrary, these embodiments are provided so that this application will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art.

[0032] In addition, the features, structures, or characteristics described in this application can be combined in any suitable manner in one or more embodiments. In the following description, there are many specific details so that the embodiments of this application can be fully understood. However, those skilled in the art should be aware that when implementing the technical solutions of this application, not all the detailed features in the embodiments may be required, one or more specific details may be omitted, or other methods, elements, devices, steps, etc. may be adopted.

[0033] In the embodiments of this application, the term "module" or "unit" refers to a computer program with a predetermined function or a part of a computer program, which works together with other related parts to achieve a predetermined goal, and can be fully or partially implemented by using software, hardware (such as a processing circuit or a memory), or a combination thereof. Similarly, one processor (or multiple processors or memories) can be used to implement one or more modules or units. In addition, each module or unit can be a part of the overall module or unit that includes the function of the module or unit.

[0034] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0035] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0036] It should be noted that the "multiple" mentioned in this article refers to two or more. "And / or" describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0037] With the development of 5G and its subsequent evolution systems (such as 5G-A, 6G, etc.), many multimedia services requiring high data volume and short latency have been applied, such as cloud gaming services, VR, AR, MR, XR, CR and other interactive services.

[0038] For example, in Figure 1 In the cloud game scenario shown, the cloud server 101 is used to run the cloud game. The cloud server 101 can render the game screen, encode the audio signal and the rendered image, and finally transmit the encoded data obtained by the encoding process to each game client through the network. The game client can be a user equipment (UE) with basic streaming media playback capabilities, human-computer interaction capabilities, and communication capabilities, such as a smart phone, tablet computer, laptop computer, desktop computer, smart TV, smart home, car terminal, aircraft, etc.; or the game client can be an application running in a terminal device. Specifically, the game client can decode the encoded data transmitted by the cloud server 101, obtain analog audio and video signals, and play them.

[0039] It should be understood that Figure 1The system architecture of the cloud gaming system is only exemplified, and the specific architecture of the cloud gaming system is not limited; for example, in other embodiments, the cloud gaming system may also include a background server for scheduling, etc. In addition, the cloud server 101 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms. The game client and the cloud server 101 can be directly or indirectly connected via wired or wireless communication, and this application does not limit this.

[0040] In the above-mentioned multimedia-based interactive service application scenarios, since the multimedia data packets are huge, they need to be split into multiple data packets for transmission. Figure 2 As shown in the figure, taking the 5G system as an example, the user plane mainly includes the application server, the user plane function (UPF), the base station (next generation node B, gNB) and the UE. For some typical business scenarios, the transmission of multimedia data packets is mainly in the downlink direction, such as from the application server to the UPF, and then sent to the UE through the gNB. During transmission, the multimedia data packet (in Figure 2 Taking the XR data packet as an example) in the application layer of the application server, after the split data packet reaches the UPF from the application server as an IP packet, the 5G system transmits the sub-data packet to the UE through the PDU session, and the UE submits it step by step from the protocol stack and reassembles it to recover the multimedia data packet.

[0041] Among them, Figure 2In the system shown, the L1 layer refers to the physical layer, which is used to ensure that raw data can be transmitted over various physical media; the L2 layer refers to the data link layer, which provides services to the network layer based on the services provided by the physical layer; the Internet Protocol (IP) layer is the network layer, which is used to implement data transmission between two end systems; UDP is the User Datagram Protocol; GTP-U is the GPRS (General Packet Radio Service) Tunneling Protocol user plane; PHY is the abbreviation of Physical, which is the physical layer in Chinese; MAC is the Media Access Control, which is the media access control in Chinese; RLC is the Radio Link Control, which is the radio link control layer protocol in Chinese; PDCP is the Packet Data Convergence Protocol, and its Chinese name is the packet data convergence protocol; SDAP is the Service Data Adaptation Protocol, and its Chinese name is the service data adaptation protocol.

[0042] As mentioned above, for multimedia services (such as XRM services), it is a common situation to divide a frame of multimedia data packets into multiple data packets for transmission. The data packets formed by a single multimedia service frame or a group of packets (GoP) may also have a relatively large byte volume and need to be carried by a series of IP data packets. There is a certain correlation between these IP data packets, and processing these packets according to the correlation can effectively save wireless network bandwidth.

[0043] For example, assume that during transmission, multiple IP data packets are used for transmission, and these multiple IP data packets can form a PDU set (PDU collection). If some data packets in the PDU set are lost, it may cause the entire frame, GoP, or other parts of the video to be unable to be decoded, and then the remaining data in the PDU set is also meaningless to the decoding end. However, if application layer forward error correction (FEC) or other mechanisms are introduced and the media application layer has a certain packet loss recovery ability or packet loss resistance ability, then the remaining data in the PDU set can still be recovered and decoded after some packets are discarded, which means that the remaining data in the PDU set is still meaningful for the receiving end to decode.

[0044] In addition, if different PDU sets are distinguished according to the correlation of application layer data packets in the QoS processing mechanism, then for PDU sets with high rates but tolerable packet loss rates or latency exceedance rates, processing can continue. In other words, the processing method for multimedia services can be more flexible. However, the related art does not provide a reasonable and effective solution for this situation.

[0045] Based on the above problems, the technical solution of the embodiments of this application proposes a new QoS processing solution for a set of service data packets, enabling adjustable QoS processing for the set of service data packets according to optional QoS policy information when processing the set of service data packets. Furthermore, the flexibility of processing the set of service data packets during the transmission of service data streams is improved, meeting the different requirements of service data streams to better cope with the challenges of high-bandwidth interactive services to wireless network transmission.

[0046] The implementation details of the technical solution of the embodiments of this application are elaborated in detail below:

[0047] Figure 3 The flowchart of the QoS processing method for a set of service data packets according to an embodiment of this application is shown. The QoS processing method for the set of service data packets can be executed by an Application Function (AF) network element or by other network elements. Referring to Figure 3 As shown, the QoS processing method for the set of service data packets includes at least S310 to S320, which are introduced in detail as follows:

[0048] In S310, QoS requirement information for a service data stream is generated, and the QoS requirement information indicates that a set of service data packets in the service data stream adopts optional QoS configuration information.

[0049] It should be noted that the set of service data packets can be a PDU set. Specifically, the service data stream can be a multimedia service data stream, such as a cloud game service data stream, a VR service data stream, an AR service data stream, an MR service data stream, an XR service data stream, an XRM service data stream, a CR service data stream, etc. Since the data packets formed by a single multimedia service frame or GoP may have a relatively large byte volume and need to be split into a series of data packets for carrying, and there is a certain correlation between these data packets, these correlated data packets can be called a PDU set.

[0050] Meanwhile, the optional QoS configuration information can be Alternative QoS Profile (AQP for short), or other QoS configuration information that meets the requirements. In this application, AQP is taken as an example. The AQP in the embodiments of this application is for a set of service data packets and is used to indicate that the QoS requirements for the set of service data packets are optional (i.e., Alternative). In this way, the QoS of the set of service data packets can be flexibly controlled to meet different requirements of service data streams. For example, for some sets of service data packets, a certain percentage of packet loss rate or delay exceedance rate can be tolerated. Then, the processing can continue through the optional QoS configuration information without having to renegotiate the QoS parameters with the core network.

[0051] In some alternative embodiments, the QoS requirement information may include optional QoS configuration information for a set of service data packets. Optionally, the optional QoS configuration information can be a selectable value range for each QoS parameter of the set of service data packets. For example, it can be a value range formed by the most preferred (prefer) value and the least preferred but still acceptable value for each QoS parameter of the set of service data packets.

[0052] Optionally, the optional QoS configuration information can be selectable values for each QoS parameter of the set of service data packets. For example, it can be several (one or more) preferred (prefer) values for each QoS parameter of the set of service data packets.

[0053] Optionally, the optional QoS configuration information can include a selectable value range for each QoS parameter of the set of service data packets and selectable values for each QoS parameter of the set of service data packets. That is, in this embodiment, the optional QoS configuration information can include a selectable value range for each QoS parameter and can also include selectable values.

[0054] Optionally, the QoS parameters for the set of service data packets included in the QoS configuration information can be at least one of the following parameters: PDU Set Delay Budget (PSDB), PDU Set Error Rate (PSER), Maximum Data Burst Volume (MDBV), Packet Delay Variation (PDV).

[0055] In some alternative embodiments, the QoS requirement information may include indication information for indicating that a set of service data packets adopts alternative QoS configuration information. That is, in this embodiment, the QoS requirement information may use the indication information to indicate that the set of service data packets may adopt alternative QoS configuration information, so that the Policy Control Function (PCF) can determine the corresponding alternative QoS policy information when the set of service data packets adopts the alternative QoS configuration information.

[0056] In some alternative embodiments, the QoS requirement information may include the media content characteristics included in the service data flow. That is, in this embodiment, the QoS requirement information may indicate the media content characteristics in the service data flow, so that the PCF can determine the corresponding alternative QoS policy information when the set of service data packets adopts the alternative QoS configuration information based on the media content characteristics.

[0057] Optionally, the media content characteristics may be used to characterize the media type. For example, based on the media content characteristics, it can be determined whether the media type is audio, video, or tactile information. In this case, the media content characteristics can to some extent reflect the QoS requirements of the corresponding media type. For example, due to higher requirements for real-time performance and interactivity, tactile information has more stringent requirements for latency compared to audio and video content. Therefore, the PCF can determine the media type based on the media content characteristics, and then determine the alternative QoS policy information for the corresponding set of service data packets when adopting the alternative QoS configuration information.

[0058] The media content characteristics can also be used to characterize the service type of the media. For example, based on the media content characteristics, it can be determined whether the service type of the media is a cloud gaming service, a remote driving service, or an email transmission service, etc. In this case, the media content characteristics can also to some extent reflect the QoS requirements of the corresponding service type. For example, due to higher requirements for real-time performance, the cloud gaming service and the remote driving service have more stringent requirements for latency compared to the email transmission service. Therefore, the PCF can determine the service type based on the media content characteristics, and then determine the alternative QoS policy information for the corresponding set of service data packets when adopting the alternative QoS configuration information.

[0059] It should be noted that in other embodiments of the present application, the QoS requirement information may also include two or more of the above information, that is, the QoS requirement information may include at least one of the following information: alternative QoS configuration information for a set of service data packets; indication information for indicating that a set of service data packets adopts alternative QoS configuration information; media content characteristics included in the service data flow.

[0060] In some alternative embodiments, the service data stream may include data of multiple media types, such as audio, video, and haptic. Then, for these media type data, it can be selected whether to use the service data packet set method for data transmission. If the service data packet set method is used for data transmission, then optional QoS configuration information can be generated for each service data packet set of various media types.

[0061] In other words, if the multiple media types in the service data stream include the target media types that use the service data packet set method for data transmission, then the QoS requirement information includes the optional QoS configuration information corresponding to each service data packet set of the target media types, so that QoS control can be performed separately for each service data packet set of different media types.

[0062] Continue to refer to Figure 3 As shown, in S320, the QoS requirement information is sent to the policy control function network element, so that the policy control function network element generates optional QoS policy information for the service data packet set according to the QoS requirement information.

[0063] In some alternative embodiments, when sending the QoS requirement information to the policy control function network element, the QoS requirement information can be directly sent to the policy control function network element. Or the QoS requirement information can also be sent to the network exposure function network element, and then the network exposure function network element forwards the QoS requirement information to the policy control function network element. Or the QoS requirement information can also be passed to the policy control function network element by negotiating a Service Level Agreement (SLA) with the policy control function network element.

[0064] The above has described the technical solution of the embodiments of the present application from the perspective of the application function network element. The following further elaborates on the implementation details of the technical solution of the embodiments of the present application in combination with Figure 4 From the perspective of the policy control function network element:

[0065] Figure 4 FIG. shows a flowchart of a QoS processing method for a service data packet set according to an embodiment of the present application. The QoS processing method for the service data packet set can be executed by the policy control function network element, or can also be executed by other network elements. Refer to Figure 4 As shown, the QoS processing method for the service data packet set at least includes S410 to S430, which are introduced in detail as follows:

[0066] In S410, QoS requirement information for the service data flow is obtained, and the QoS requirement information indicates that a set of service data packets in the service data flow adopts optional QoS configuration information.

[0067] In some optional embodiments, the set of service data packets may be a PDU set, and there is a certain correlation between the data packets in the PDU set. The optional QoS configuration information is the AQP. The AQP in the embodiments of the present application is for the set of service data packets and is used to indicate that the QoS requirement of the set of service data packets is optional (i.e., Alternative). In this way, the QoS of the set of service data packets can be flexibly controlled to meet different requirements of the service data flow. For example, for some sets of service data packets, a certain packet loss rate or latency exceedance rate can be tolerated, and then the processing can continue through the optional QoS configuration information without having to renegotiate the QoS parameters with the core network.

[0068] It should be noted that the content included in the QoS requirement information can refer to the technical solutions of the foregoing embodiments and will not be elaborated herein.

[0069] In S420, optional QoS policy information for the set of service data packets is generated according to the QoS requirement information.

[0070] In some optional embodiments, the optional QoS policy information may include whether to map data of different media types included in the service data flow to different QoS flows. For example, the service data flow may include data of multiple media types such as audio, video, and tactile. Then, the QoS policy information may include whether to map data of different media types to different QoS flows, that is, data of various media types use separate QoS flows. Of course, the optional QoS policy information may directly include indication information for mapping data of different media types included in the service data flow to different QoS flows, or include indication information for not mapping data of different media types included in the service data flow to different QoS flows (such as mapping data of different media types included in the service data flow to the same QoS flow).

[0071] In some optional embodiments, the optional QoS policy information may include whether to map data of different media types included in the service data flow to the same QoS flow, that is, data of different media types in the service data flow use the same QoS flow. Of course, the optional QoS policy information may directly include indication information for mapping data of different media types included in the service data flow to the same QoS flow.

[0072] In some optional embodiments, the optional QoS policy information may include whether to indicate the importance of different media types through the importance information of the service data packet set when mapping data of different media types included in the service data stream to different QoS flows. Of course, in the optional QoS policy information, when directly mapping data of different media types included in the service data stream to different QoS flows, the importance of different media types can be indicated through the importance information of the service data packet set (i.e., PDU set important). If the importance of different media types is indicated, then when performing data transmission, the QoS of service data packets of high-priority media types can be preferentially guaranteed.

[0073] In some optional embodiments, the optional QoS policy information may include that if data of different media types included in the service data stream are mapped to the same QoS flow, the optional QoS policy information represents an integrated policy for the same QoS flow. That is, the optional QoS policy information is for data packets of different media types carried on the same QoS flow.

[0074] In some optional embodiments, the optional QoS policy information may also include a combination of two or more types of information in the above information.

[0075] In some optional embodiments, the process of generating optional QoS policy information for the service data packet set according to the QoS requirement information may be as follows: If the QoS requirement information includes optional QoS configuration information corresponding to service data packet sets of different media types respectively, and data of different media types are mapped to the same QoS flow, then an integrated policy for the same QoS flow can be generated according to the optional QoS configuration information corresponding to service data packet sets of different media types respectively. That is, in this embodiment, if data of different media types are mapped to the same QoS flow, then when generating QoS policy information, the optional QoS configuration information corresponding to service data packet sets of these media types can be integrated to generate an integrated policy information.

[0076] Optionally, if the optional QoS configuration information includes bandwidth requirement information, then the bandwidth requirement information of different media types can be superimposed to generate an integrated policy for the bandwidth requirement information.

[0077] Optionally, if the optional QoS configuration information includes PSDR requirement information, then an integrated policy for the PSDR requirement information can be generated according to the minimum value of the PSDR requirements in different media types. This is because when selecting the minimum value of the PSDR requirements in different media types, the PSDR requirements of service data packet sets of all media types can be met.

[0078] Optionally, if the optional QoS configuration information includes PSER requirement information, a comprehensive policy for the PSER requirement information can be generated based on the minimum value of the PSER requirements in different media types. This is because when selecting the minimum value of the PSER requirements in different media types, the PSER requirements of the service data packet sets of all media types can be satisfied.

[0079] Optionally, if the optional QoS configuration information includes MDBV requirement information, a comprehensive policy for the MDBV requirement information can be generated based on the maximum value of the MDBV requirements in different media types. This is because when selecting the maximum value of the MDBV requirements in different media types, the MDBV requirements of the service data packet sets of all media types can be satisfied. Alternatively, the MDBV requirement information in different media types can also be superimposed to generate a comprehensive policy for the MDBV requirement information.

[0080] Optionally, if the optional QoS configuration information includes PDV requirement information, a comprehensive policy for the PDV requirement information can be generated based on the minimum value of the PDV requirements in different media types. This is because when selecting the minimum value of the PDV requirements in different media types, the PDV requirements of the service data packet sets of all media types can be satisfied.

[0081] In some optional embodiments, the process of generating optional QoS policy information for a service data packet set according to QoS requirement information may be: if the data of different media types included in the service data stream are mapped to different QoS flows, optional QoS policy information can be generated respectively for the service data packet sets in different QoS flows. The technical solution of this embodiment enables QoS control to be performed separately on different QoS flows based on the optional QoS policy information when mapping the data of different media types to different QoS flows.

[0082] In some optional embodiments, the optional QoS policy information includes at least one of the following information: the selectable value range of each QoS parameter for the service data packet set; the selectable value of each QoS parameter for the service data packet set.

[0083] In some optional embodiments, the optional QoS policy information may include the selectable value range of each QoS parameter for the service data packet set, such as the value range formed by the most preferred (prefer) value and the least preferred but still acceptable value of each QoS parameter for the service data packet set.

[0084] In some alternative embodiments, the optional QoS policy information may also include selectable values for each QoS parameter for the set of service data packets, such as several (one or more) preferred values for each QoS parameter for the set of service data packets.

[0085] In some alternative embodiments, the optional QoS policy information may also include a range of selectable values for each QoS parameter for the set of service data packets, as well as selectable values for each QoS parameter for the set of service data packets. That is, in this embodiment, the optional QoS policy information may include a range of selectable values for each QoS parameter, and may also include selectable values.

[0086] Optionally, the QoS parameters for the set of service data packets included in the QoS policy information may be at least one of the following parameters: PSDB, PSER, MDBV, PDV.

[0087] In some alternative embodiments, the process of generating optional QoS policy information for the set of service data packets according to the QoS requirement information may be to generate optional QoS policy information associated with the user equipment and for the set of service data packets according to the QoS requirement information and the subscription information of the user equipment for processing the set of service data packets. For example, if it is determined according to the subscription information of the user equipment that the priority of the user equipment is relatively high (such as the corresponding account is a membership account, the type of service processed has a relatively high requirement for latency, etc.), then the generated optional QoS policy information for the set of service data packets needs to ensure that the user equipment with a relatively high priority has a better quality of service.

[0088] In some alternative embodiments, the process of generating optional QoS policy information for the set of service data packets according to the QoS requirement information may also be to generate optional QoS policy information for the set of service data packets according to the QoS requirement information and the service level agreement negotiated with the application function network element. For example, if it is determined according to the service level agreement that the priority of certain user equipment is relatively high (such as the corresponding account is a membership account), then the generated optional QoS policy information for the set of service data packets needs to ensure that these user equipment with a relatively high priority have a better quality of service.

[0089] Continue to refer to Figure 4 As shown, in S430, the optional QoS policy information is sent to the Session Management Function (SMF) so that the SMF configures the optional QoS policy information to the device for processing the set of service data packets.

[0090] In some alternative embodiments, the SMF may send optional QoS policy information for a set of service data packets to the UPF, gNB, and UE.

[0091] Specifically, taking the 5G system as an example, as Figure 5 shown is the key network element architecture of the 5G network defined by the 3rd Generation Partnership Project (3GPP) organization. Among them, the Access and Mobility Management Function (AMF), SMF, UPF, PCF, Network Slice Selection Function (NSSF), Authentication Server Function (AUSF), Unified Data Management (UDM), etc. are the core network elements of the 5G network. The UE may be a 5G terminal such as a mobile phone or a tablet computer; the (R)AN ((Radio) Access Network) may be a 5G base station; the DN (Data Network) is the data network, that is, the service server accessed by the UE.

[0092] Among them, the AMF is responsible for terminating the N2 interface of the base station control plane and implementing the encoding and decoding of the Next Generation Application Protocol (NGAP) based on the Stream Control Transmission Protocol (SCTP). The base station and the AMF transmit the application layer NGAP protocol through the SCTP transport layer protocol and carry the non-access stratum (NAS) signaling data of the UE in the NGAP. The AMF is also responsible for terminating the N1 interface of the UE, implementing the encryption and integrity protection of the NAS, and is responsible for functions such as UE access verification, authorization management, registration, connection, reachability, and mobility management, as well as the transparent transmission of session management messages between the UE and the SMF.

[0093] In addition, (R)AN and UPF interact through the N3 interface; UPFs can interact through the N9 interface; UPF and SMF interact through the N4 interface; UPF and DN interact through the N6 interface; SMF and AMF interact through the N11 interface; SMF and PCF interact through the N7 interface; SMF and UDM interact through the N10 interface; PCF and AF interact through the N5 interface; AMFs can interact through the N14 interface; AMF and PCF interact through the N15 interface; AMF and UDM interact through the N8 interface; AMF and NSSF interact through the N22 interface; AMF and AUSF interact through the N12 interface; AUSF and UDM interact through the N13 interface.

[0094] Based on Figure 5 In the system architecture shown, the SMF can configure optional QoS policy information for the service data packet set to the UPF through the N4 interface. And configure optional QoS policy information for the service data packet set to the (R)AN through the AMF, and configure optional QoS policy information for the service data packet set to the UE through the AMF+NAS connection.

[0095] The technical solutions of the embodiments of the present application have been described above from the perspectives of the application function network element and the policy control function network element. The following further elaborates on the implementation details of the technical solutions of the embodiments of the present application in combination with Figure 6 the access network device:

[0096] Figure 6 FIG. shows a flowchart of a QoS processing method for a service data packet set according to an embodiment of the present application. The QoS processing method for the service data packet set can be executed by an access network device (such as a user equipment or a base station), or can also be executed by other devices. Referring to Figure 6 shown, the QoS processing method for the service data packet set at least includes S610 to S630, which are introduced in detail as follows:

[0097] In S610, receive optional QoS policy information for the service data packet set. The optional QoS policy information is generated by the policy control function network element according to the QoS requirement information of the service data stream. The QoS requirement information indicates that the service data packet set in the service data stream adopts optional QoS configuration information.

[0098] In some alternative embodiments, the set of service data packets may be a PDU set, and there is a certain correlation between the data packets in the PDU set. The optional QoS configuration information is the AQP. The AQP in the embodiments of the present application is for the set of service data packets and is used to indicate that the QoS requirement of the set of service data packets is optional (i.e., Alternative). In this way, the QoS of the set of service data packets can be flexibly controlled to meet different requirements of service data flows. For example, for some sets of service data packets, a certain packet loss rate or delay exceedance rate can be tolerated, and then the processing can continue through the optional QoS configuration information without having to renegotiate the QoS parameters with the core network.

[0099] It should be noted that the content included in the QoS requirement information and the process of generating the QoS policy information can refer to the technical solutions of the foregoing embodiments and will not be elaborated herein.

[0100] In S620, the QoS parameters of the set of service data packets during transmission are detected.

[0101] In some alternative embodiments, detecting the QoS parameters of the set of service data packets during transmission may be detecting at least one of the following parameters: PSDB, PSER, MDBV, PDV.

[0102] In S630, if the QoS parameters of the set of service data packets during transmission do not match the optional QoS policy information, a notification message is sent to the core network element to trigger the PDU session modification process.

[0103] In some alternative embodiments, if a certain QoS parameter of the set of service data packets during transmission fails to meet the requirements, the QoS parameter can be reselected according to the range indicated in the optional QoS policy information. In this case, there is no need to interact with the core network to trigger the PDU session modification process, but a message can be sent to the core network to notify that the QoS parameter has been changed. If a certain QoS parameter of the set of service data packets during transmission exceeds the range indicated in the optional QoS policy information, it means that the QoS parameters of the set of service data packets during transmission do not match the optional QoS policy information. Furthermore, a notification message can be sent to the core network element to trigger the PDU session modification process to update the QoS requirement information.

[0104] It can be seen that the technical solution of the embodiment of the present application mainly focuses on the service data packet set (i.e., PDU set), and introduces an optional QoS mechanism, so that the adaptive selection of the QoS profile can be performed at the Next Generation - Radio Access Network (NG - RAN) node, realizing the adjustable QoS processing of the PDU set and meeting the different requirements of service data streams.

[0105] Specifically, as Figure 7 shown, the QoS processing method for the service data packet set according to an embodiment of the present application includes the following steps:

[0106] S701, the AF provides optional PDU set QoS requirements and PCC (Policy Control and Charging) policy guidance information.

[0107] In some optional embodiments, the AF can provide optional QoS requirements for the PDU set, such as what can be called the PDU set - aware AQP mechanism (i.e., PDU set - aware AQP), and the AF can provide fine - grained Alternative QoS requirements.

[0108] Specifically, if the media service flow includes different media types (such as audio, video, haptic, etc.), then these media types can start or not start the PDU set mechanism, that is, they can choose whether to use the PDU set method for data transmission.

[0109] If multiple media types start the PDU set mechanism, then the AF can indicate the PDU set - aware AQP supported by different media types respectively. If some media types do not start the PDU set mechanism, the AF can provide the PDU set - aware AQP for the service flows that have started the PDU set mechanism, and provide other QoS requirements for the service flows that have not started the PDU set mechanism.

[0110] It should be noted that the QoS requirements provided for the service flows that have not started the PDU set mechanism can include QoS parameters for data packets, such as Packet Error Rate (PER), Packet Delay Budget (PDB), etc. And the PDU set - aware AQP provided for the service flows that have started the PDU set mechanism can include QoS parameters for the PDU set, such as PSDB, PSER, MDBV, PDV, etc.

[0111] Optionally, the PDU set aware AQP provided for the traffic flow that has initiated the PDU set mechanism may also include QoS parameters for data packets. In this case, it can be understood that the QoS requirements for data packets in the existing standard protocol are reused, that is, the QoS parameters for the PDU set are added to this QoS requirement. Of course, a brand-new QoS requirement for the PDU set can also be used to include the QoS parameter information for the PDU set.

[0112] In some alternative embodiments, the optional QoS requirements and PCC policy guidance information provided by the AF for the PDU set are not PCC rules. Therefore, they can be described from the perspective of service requirements without the need to provide each parameter of the PCC rule. The content of an example PDU set aware AQP is as Figure 8 shown. Taking the media traffic flow that includes three media types as an example, the PDU set aware AQP includes the QoS requirements for each media type (i.e., the QoS requirements for media type 1, the QoS requirements for media type 2, and the QoS requirements for media type 3). Each QoS requirement for a media type includes the QoS parameter values (such as PSDB, PSER, MDBV, and PDV, etc.) from the most preferred to the least preferred but still acceptable (i.e., Most to least preferred QoS parameter value).

[0113] In some alternative embodiments, in order to reduce the amount of information exchanged between the AF and the 5GC (5G Core), the AF and the 5GC can also reflect the PDU set aware AQP by negotiating the SLA. In this case, the SLA can include the alternative QoS parameter ranges for different media types.

[0114] S702, the PCF generates an optional QoS rule for the PDU set.

[0115] In some alternative embodiments, after the AF sends the Alternative QoS requirements for the PDU set (i.e., the PDU set aware AQP) to the PCF, or sends it to the PCF through the NEF network element, or notifies the PCF through SLA negotiation, the PCF can generate PDU set aware alternative QoS rules (i.e., the optional QoS policies / rules for the PDU set) based on the user's subscription information or the SLA with the AF. The generated QoS rules include but are not limited to the following information:

[0116] Whether to map data of different media types in the media service flow to different QoS flows; if so, whether to indicate the importance of different media types through PDU set importance; if the data of different media types in the media service flow are mapped to the same QoS flow, then the configured PDU set aware QoS rules are comprehensive QoS rules for multiple media types.

[0117] In some alternative embodiments, if the data of different media types in the media service flow are mapped to the same QoS flow and the configured PDU set aware QoS rules are comprehensive QoS rules for multiple media types, then even if the PDU set aware AQP provided by the AF differentiates media types, the PCF can still generate comprehensive QoS rules according to the requirements of different media types.

[0118] Optionally, when generating comprehensive QoS rules, the PCF can add up the bandwidth requirements of various media types to generate a comprehensive bandwidth requirement.

[0119] Optionally, the PCF can also add up the bandwidth requirements of various media types as the comprehensive requirement for MDBV. Or the maximum value of the MDBV requirements of various media types can be used as the comprehensive requirement for MDBV.

[0120] Optionally, the PCF can comprehensively consider the delay requirements (i.e., PSDB) of various media types, take the minimum value of the most preferred delay requirements of all media types as the most preferred delay value obtained by synthesis, and take the minimum value among the least preferred but acceptable delay values of all media types as the least preferred delay value obtained by synthesis.

[0121] Optionally, the PCF can comprehensively consider the PSER of various media types, take the minimum value of the most preferred PSER of all media types as the most preferred PSER value obtained by synthesis, and take the minimum value among the least preferred but acceptable PSER values of all media types as the least preferred PSER value obtained by synthesis.

[0122] In some alternative embodiments, if different media types are mapped to different QoS flows, the configured PDU set aware Alternative QoS rules can be generated separately for different media types. That is, the QoS rules are for these multiple QoS flows respectively, and the QoS rule includes optional PDU set QoS parameters. The content included in an exemplary QoS rule is asFigure 9 As shown in the figure. Taking the case where the media service flow includes three media types as an example, the PDUsetawareAlternativeQoSrules includes QoS rules for QoS flows of each media type (i.e., QoS rules for QoS flows of media type 1, QoS rules for QoS flows of media type 2, and QoS rules for QoS flows of media type 3). The QoS rules for QoS flows of each media type include the most preferred to the least preferred but still acceptable QoS parameter values (i.e., MosttoleastpreferredQoSparametervalue) of each QoS parameter (such as PSDB, PSER, MDBV, and PDV, etc.).

[0123] S703, the SMF configures alternative QoS rules for the PDU set for the NG-RAN and the UE.

[0124] In some alternative embodiments, after generating the PDUsetawareAlternativeQoSrules, the PCF sends them to the SMF, and then the SMF configures QoS rules for the UPF through the N4 interface, which includes alternative QoS rules for QoS flows of different media types.

[0125] Meanwhile, the SMF configures the PDUsetawareAlternativeQoSrules for the NG-RAN through the AMF, and the SMF configures the PDUsetawareAlternativeQoSrules for the UE through the AMF+NAS connection.

[0126] S704, the NG-RAN and the UE execute the process of PDUsetaware AlternativeQoS requirements.

[0127] In some alternative embodiments, the NG-RAN and the UE perform data transmission on the Uu interface according to the PDUsetawareAlternativeQoSrules configured by the 5GC. According to end-to-end and radio interface-only QoS monitoring, the NG-RAN can dynamically observe whether parameters such as PSDB, PSER, and PDV have exceeded the range of PDUsetawareQoS requirements. If so, it triggers a PDU session modification or other processes to notify the 5GC and the AF to take corresponding actions.

[0128] The following refers to Figure 10 As shown in the figure, a specific example is used to elaborate in detail on the technical solution of the embodiment of the present application, which specifically includes the following steps:

[0129] S1001. After the PDU session is successfully established, the AF performs signaling interaction with the 5G system (5GS) to indicate the optional QoS requirements for the PDU sets of different media types.

[0130] S1002. Based on the information provided by the AF, the PCF generates optional QoS policies, including QoS rules for single or multiple QoS flows and multiple media types.

[0131] For example, if data of different media types are mapped to the same QoS flow, the PCF can generate comprehensive QoS rules according to the requirements of different media types. If different media types are mapped to different QoS flows, the PCF can generate PDU set-aware alternative QoS rules for different media types respectively.

[0132] S1003. The 5GC configures the optional QoS policy information to the UPF, the base station, and the UE.

[0133] Optionally, after generating the PDU set-aware alternative QoS rules, the PCF sends them to the SMF. The SMF configures them to the UPF through the N4 interface, configures them to the NG-RAN through the AMF, and configures them to the UE through the AMF+NAS connection.

[0134] S1004. The PDU set identifier and label are used to cooperate with the RAN to monitor and count for the optional QoS rules.

[0135] S1005. Process the PDU set in combination with the optional QoS rules

[0136] For example, if it is detected that parameters such as PSDB, PSER, and PDV have exceeded the range of the PDU set-aware QoS requirements, a notification message is sent to the core network to trigger PDU session modification or other processes.

[0137] In summary, the technical solution of the embodiment of the present application mainly introduces a PDU set-aware AQP mechanism for the PDU sets of multimedia services such as XR. When the AF provides fine-grained QoS requirements based on media types to the 5GC, it indicates the optional PDU set QoS requirements (including optional PDU set QoS parameters, etc.). After the 5GC and the NG-RAN nodes generate PCC policies and establish PDU sessions and QoS flows in the core network, the NG-RAN nodes perform adaptive selection of QoS profiles to achieve adjustable QoS processing for the PDU sets and meet the different requirements of service data streams.
