[0144] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0145] The following embodiments of this disclosure can be applied to Figure 1A The communication system 100 shown, or a part thereof, but not limited to it. Figure 1A The entities shown are illustrative; a communication system may include... Figure 1A All or part of the main body, or may include Figure 1A Other entities besides the main body, the number and form of each entity are arbitrary, the connection relationship between the entities is illustrative, the entities may not be connected or may be connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0146] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), public land mobile network (PLMN) networks, device-to-device (D2D) systems, machine-to-machine (M2M) systems, Internet of Things (IoT) systems, vehicle-to-everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0147] In some embodiments, the ITU-R has described immersive communications. It extends the Enhanced Mobile Broadband (eMBB) of IMT-2020 and covers use cases that provide users with rich, interactive video (immersive) experiences, including interaction with machine interfaces.

[0148] Compared to existing 5G network-based AR / VR services, 6G immersive XR services aim to provide an ultimate user experience through ultra-high resolution, high frame rate, wide color gamut, high dynamic range, wide field of view, and advanced encoding / compression technologies. It supports more natural interaction methods (e.g., voice interaction, gesture interaction, head interaction, eye tracking) to achieve complex perception of users and their environment. The 6G system and service platform need to work together to complete the rendering, synchronization, encoding, distribution, storage, and management of immersive XR services, supporting real-time transmission and processing of panoramic video data, FOV video data, and more.

[0149] With the increasing prevalence of extended reality in the 5G era, 5G-Advanced and 6G are expected to expand immersive experiences for both enterprise and mass consumer markets. In 6G, users of immersive technologies can expect to work, play, and interact seamlessly in both the physical and virtual worlds. These immersive experiences will be achieved by leveraging advanced extended reality (XR) and multimedia capabilities, such as user interaction through holographic conferencing, spatial collaboration with high-fidelity 3D objects, high-resolution immersive 2D-3D cloud gaming, high-resolution 360° 2D-3D content streaming, and user experiences mediated by multimodal AI.

[0150] The communication system already supports enhanced methods for immersive services, including multimodal QoS flow indication, round trip time (RTT), packet data unit (PDU) set-based processing, congestion control (L4S), data burst marking, time stamping to the next burst, and data enhancement to accelerate transmission. For PDU set-based processing, PDU set QoS parameters have been introduced, including PDU set delay budget (PSDB), PDU set error rate (PSER), and PDU set integrated handling information (PSIHI). PDU set information has also been introduced, including PDU set sequence number, PDU set end PDU indication, PDU sequence number within the PDU set, PDU set size in bytes, and PDU set importance.

[0151] However, for immersive service traffic, effectively adapting to the QoS requirements of immersive services (including ultra-high resolution, high frame rate, wide color gamut, high dynamic range, wide field of view, and advanced encoding / compression techniques) and efficient resource management remains a key challenge. For example, better QoE can often be quantified by higher QoS support (higher bitrates result in better QoE), but this is a diminishing return. QoE can be measured using different metrics, depending not only on application QoS but also on the dynamic state of the network and the dynamic complexity of the media service.

[0152] Therefore, how to support and optimize QoE for services such as immersive services is a technical problem that needs to be solved.

[0153] To address the aforementioned issues, embodiments of this disclosure provide a communication method, communication device, communication system, storage medium, and program product that perform content-based QoS processing on media data streams, thereby enabling support for and optimization of QoE for services such as immersive services.

[0154] Figure 2 This is a schematic diagram of a first interaction of a communication method provided according to an embodiment of this disclosure. For example... Figure 2 As shown, this disclosure relates to a communication method. Executed by a communication system 100, the communication method includes steps S201 to S217.

[0155] In step S201, the second network element 1032 sends the first information to the fifth network element 1035.

[0156] In some embodiments, the second network element 1032 can send the first information. In some embodiments, the first information can be sent by the second network element 1032, but is not limited thereto, and can also be sent by other entities.

[0157] In some embodiments, the fifth network element 1035 can receive the first information. In some embodiments, the first information can be received by the fifth network element 1035, but is not limited thereto, and can also be received by other entities.

[0158] In some embodiments, the first information may be sent when the second network element 1032 requests the establishment of a session for the first service. In some embodiments, the second network element 1032 may send the first information when it determines that a session needs to be established for the first service.

[0159] In some embodiments, the first service may be a service related to immersive communication. In one example, the first service may include XR service, XRM service, AXR service, or interactive media service. In some embodiments, the first service may also be other types of services, which are not specifically limited in this disclosure.

[0160] In some embodiments, the data flow of the first service may include a media data flow, which may also be referred to as a multimedia data flow or media stream. In one embodiment, the media data flow may be a composite stream composed of multiple types of data, used to realize audio and video transmission, interactive control, and immersive experience. In one example, the media data flow may include basic media data, such as video data, audio data, metadata, etc., and may also include immersive extended data, such as 3D / XR data (e.g., point clouds, depth maps, field of view, eye-tracking data, head posture data, etc.), sensory data (e.g., haptic feedback data, environmental data, etc.), and control and interaction data, such as network control information (e.g., QoS parameters, congestion signals, etc.), user interaction information, AI-enhanced data (e.g., neural network parameters), holographic data (e.g., light field encoding, phase information, etc.), intent metadata, etc.

[0161] In some embodiments, the first information may be used to request content-based QoS processing to be performed on a data stream (such as a media data stream) of a first service. In some embodiments, the first information may be used to request the application of content-based QoS configuration to a data stream (such as a media data stream) of a first service. In some embodiments, the first information is used to indicate content-based QoS requirements associated with a data stream (media data stream) of a first service.

[0162] In some embodiments, content-based QoS processing is a feature, or a function. In one embodiment, content-based QoS processing may also be referred to as content-based adaptive QoS handling.

[0163] In some embodiments, the name of the first information is not limited, and it may be, for example, request information, instruction information, demand information, etc.

[0164] In some embodiments, the data stream of the first service may include one or more media data streams. Therefore, content-based QoS processing of the data stream of the first service can be applied to a single media data stream (e.g., in a single-stream scenario) or to multiple media data streams (e.g., in a cross-stream scenario).

[0165] In some embodiments, the first information may include at least one of the following: indication information, level information, mapping information, and priority information.

[0166] In some embodiments, the indication information is used to indicate support for content-based QoS processing. In some embodiments, the indication information is used to indicate that the core network supports content-based QoS processing. In some embodiments, the indication information is used to indicate that the communication system supports content-based QoS processing. In one embodiment, the indication information is used to request the core network to support content-based QoS processing. In one embodiment, the indication information is used to request the communication system to support content-based QoS processing.

[0167] In some embodiments, the level information is used to indicate the service content level associated with a data stream of a first service. In one embodiment, the level information is used to indicate the service content level associated with one or more media data streams of the first service. In some embodiments, the level information is used to request the service content level associated with a data stream of the first service. In one embodiment, the level information is used to request the service content level associated with one or more media data streams of the first service.

[0168] In some embodiments, data in a media data stream can be divided into one or more service content levels based on content. In this case, the media data stream can be associated with one or more service content levels. In one embodiment, among multiple media data streams, the service content levels associated with different media data streams can be completely identical, partially identical, or completely different. In this case, a service content level can be associated with one or more media data streams.

[0169] In one example, for a single-stream scenario, the data stream of the first service is a single media data stream, which can be associated with one or more service content levels.

[0170] In one example, for a cross-stream scenario, the data stream of the first service includes multiple media data streams, and each media data stream can be associated with one or more service content levels. In this case, each media data stream can be associated with one service content level, and these service content levels can be the same; that is, one service content level is associated with multiple media data streams. Alternatively, each media data stream can be associated with one service content level, and these service content levels can be different; that is, one service content level is associated with one media data stream. Or, some media data streams are associated with one service content level, while others are associated with multiple service content levels. These service content levels can be the same or different.

[0171] In some embodiments, the service content level is determined considering the content complexity of the service data of a first service. In one embodiment, the content complexity of the service data can be associated with spatial complexity, temporal complexity, frequency complexity, etc. In one example, the service content level can include a simple content level, a complex content level, and a semi-complex content level. For example, data at the simple content level can be video frames without frequency, temporal, and / or spatial variations. In this case, the video frame can be static. Alternatively, data at the simple content level can be video frames with frequency, temporal, and / or spatial variations less than a certain threshold. In this case, the video frame can be semi-static. Data at the complex content level can be video frames with high dynamics and rich spatial information. In this case, the video frame has frequent frequency, temporal, and / or spatial variations, and the video frame is a high dynamic range video frame. Data at the semi-complex content level lies between the data at the simple content level and the data at the complex content level. Data at the semi-complex content level can be video frames where some of the frequency, temporal, and spatial variations are less than a certain threshold, but others vary frequently.

[0172] In some embodiments, the service content level may also consider other information, such as the dependencies between the service data of the first service and other related data. In one embodiment, other related data may be data streams from other services or other data associated with the service data of the first service. In one embodiment, the service content level may be determined based on a comprehensive assessment of the content complexity of the service data of the first service and the dependencies between the service data of the first service and other related data.

[0173] In one example, the service content level C1 is the media data stream of the first service, and the service content level C2 is the data stream of other services associated with the media data stream. Since the service content level C1 is higher than the service content level C2, the service content level corresponding to the media data stream of the first service can also be determined as the service content level C2.

[0174] In some embodiments, there may be other situations regarding the service content level, which are not specifically limited in this disclosure.

[0175] In some embodiments, the mapping information is used to indicate content-based QoS allocation rules. In one embodiment, the mapping information is used to indicate the mapping relationship between the service content level associated with the data flow of the first service and the QoS configuration. In one embodiment, the mapping information is used to request the mapping relationship between the service content level associated with the data flow of the first service and the QoS configuration.

[0176] In some embodiments, priority information is used to indicate the priority of QoS configuration for content-based QoS processing. In one embodiment, priority information is used to indicate the priority of QoS configuration for a service content level map associated with a data flow of a first service. In one embodiment, priority information is used to request the priority of QoS configuration for a service content level map associated with a data flow of a first service.

[0177] In some embodiments, the first information may also include other information, which is not specifically limited in this disclosure.

[0178] In some embodiments, the second network element 1032 may send the first information through a QoS request process or a QoS update process. In some embodiments, the first information may be carried in a request message. In one example, the first information may be carried in an AF request. In some embodiments, the second network element 1032 may send a session resource request. This session resource request may carry the first information. In some embodiments, the session resource request may be a session resource creation request. In one example, the session resource request may be an AF session resource request, such as an Nnef_AFSessionwithQoS_Create request message. In some embodiments, the session resource request may be an AF session resource update request, such as an Nnef_AFSessionwithQoS_Update request message.

[0179] In some embodiments, the first information may be included in the QoS requirements for the data stream of the first service. In some embodiments, the second network element 1032 may send an AF request to the fifth network element 1035, the AF request may carry content-based QoS requirements for the data stream of the first service, and the content-based QoS requirements may include the first information. In some embodiments, the first information may be independent of the QoS requirements.

[0180] In some embodiments, while sending the first information, the second network element 1032 may also send service information of the first service to the fifth network element 1035.

[0182] In some embodiments, the fifth network element 1035 can authorize a request message carrying first information. In some embodiments, the fifth network element 1035 can authorize first information from the second network element 1032.

[0183] In some embodiments, the second network element 1032 may be an unauthorized network element, in which case the fifth network element 1035 may authorize the request message from the second network element 1032.

[0184] In some embodiments, the second network element 1032 may be an authorized network element, in which case the fifth network element 1035 may not need to authorize the request message from the second network element 1032. In other words, step S202 may be omitted.

[0189] In some embodiments, the fifth network element 1035 can send the first information in different ways.

[0190] In some embodiments, the fifth network element 1035 may send the first information in the following ways: by sending via time-sensitive communication and time synchronization function (TSCTSF) or by sending directly.

[0191] In some embodiments, the fifth network element 1035 can send the first information to the first network element 1031 via TCSTSF.

[0192] In some embodiments, the fifth network element 1035 can send the first information to the TSCTSF via the service-based interface Ntsftsf, and then the TSCTSF can send the first information to the first network element 1031 via the service-based interface Npcf. In one example, the fifth network element 1035 can send the first information to the TSCTSF via an Ntsctsf_QoSandTSCAssistance_Create request message or an Ntsctsf_QoSandTSCAssistance_Update request message, and then the TSCTSF can send the first information to the first network element 1031 via an Npcf_PolicyAuthorization_Create request message or an Npcf_PolicyAuthorization_Update request message.

[0193] In some embodiments, the fifth network element 1035 can directly send the first information to the first network element 1031.

[0194] In some embodiments, the fifth network element 1035 can send the first information to the first network element 1031 through the service-based interface Npcf. In one example, the fifth network element 1035 can send the first information to the first network element 1031 through an Npcf_PolicyAuthorization_Create request message or an Npcf_PolicyAuthorization_Update request message.

[0195] In some embodiments, the first network element 1031 can obtain first information from the second network element 1032 through steps S201 to S203. In some embodiments, the first network element 1031 can obtain the first information through other means. In this case, steps S201 to S203 can be omitted. For example, the first network element 1031 can determine the first information based on operator policies, and / or operations, administration and maintenance (OAM) configurations, and / or local configurations.

[0196] In step S204, the first network element 1031 performs a strategy decision.

[0197] In some embodiments, the first network element 1031 may perform a policy decision based on at least one of the received first information, the service information of the first service, and the configuration information of the first network element 1031.

In some embodiments, the first network element 1031 can authorize the media data stream of the first service based on at least one of the first information, the service information of the first service, and the configuration information of the first network element 1031. In one embodiment, the first network element 1031 can authorize one or more QoS protocols for the media data stream of the first service, and these QoS protocols can be used for content-based QoS processing. In this case, the QoS authorized by the first network element 1031 can be the authorized content-based QoS.

[0199] In some embodiments, in step S204, the first network element 1031 may also determine a first rule.

[0200] In some embodiments, the first rule is used to perform content-based QoS processing on the data stream of the first service. In one embodiment, the first rule can also be used for other network control functions associated with the data stream of the first service, such as decision-making, gating, QoS, and charging.

[0201] In some embodiments, the first rule may include authorized content-based QoS, and may also include at least one of indication information, rating information, mapping information, and priority information.

[0202] In some embodiments, the first rule may be determined by the first network element 1031 when authorizing the data flow of the first service. In some embodiments, when the data flow of the first service is authorized, the first network element 1031 may determine the first rule based on at least one of the first information, the service information of the first service, and the configuration information of the first network element 1031.

[0203] In some embodiments, the first rule determined by the first network element 1031 may be a new first rule. In some embodiments, the first rule determined by the first network element 1031 may be an updated first rule.

[0204] In some embodiments, the first rule may be a policy and charging control (PCC) rule.

In some embodiments, the authorization result may be that the AF request of the second network element 1032 has been authorized. In some embodiments, the first network element 1031 may send a response message to the fifth network element 1035. For example, the first network element 1031 may send an Npcf_PolicyAuthorization_Update response message to the fifth network element 1035. In some embodiments, the fifth network element 1035 may send a response message to the second network element 1032.

[0354] In some embodiments, content-based adaptive QoS indications, CoS level information, mapping lists between QoS profiles and CoS levels, and priority lists of QoS profiles with CoS levels may be provided by the application service provider (ASP) of the immersive service, the service agent of the operator in the PCF or PLMN or SNPN, to indicate auxiliary information for content-based adaptive QoS processing enabled in the 6G network.

[0355] In some embodiments, content-based adaptive QoS indications, CoS level information, mapping lists between QoS profiles and CoS levels, and priority lists of QoS profiles with CoS levels can be provided to 6G immersive service operation functions (e.g., PCF, SMF, UPF, service agent) to support the implementation of content-based adaptive QoS determination, authorization, and DL and / or UL immersive service media streams.

[0356] In some embodiments, for CoS-level information, different content complexities (e.g., simple content, semi-complex content, complex content) and granularities of media information can be considered for allocation. For example, as described below:

[0357] Simple content refers to media information (e.g., video frames with little frequency or temporal variation (i.e., static or semi-static) or spatial variation (i.e., mostly ordinary)).

[0358] Complex content refers to media information (such as video frames with high dynamic range and rich spatial information).

[0359] Semi-complex content refers to media information that has semi-static temporal and / or spatial information changes, falling between simple and complex content.

[0360] In some embodiments, for a data network (DN) or AF:

[0361] AF (such as Immersive Service ASP) provides QoS requirements for media streams to 6G immersive service operation functions (such as PCF, SMF, UPF, serviceagent), including content-based adaptive QoS indications, CoS level information, a mapping list between QoS profiles and CoS levels, and a priority list of QoS profiles with CoS levels.

[0362] In one embodiment, the AF may provide the above information to the core network (e.g., NEF or PCF) during the AF QoS request / update process.

[0363] In some embodiments, for the first control plane network element (CP NF) or PCF or service agent:

[0364] The first CP NF or PCF or service agent authorizes and provides content-based adaptive QoS for service data flows, as well as other network controls (e.g., in PCC rules) to the SMF regarding the detection, gating, QoS, and charging of service data flows, taking into account:

[0365] Content-based adaptive QoS indication to indicate support for content-based adaptive QoS processing.

[0366] Content-of-Service (CoS) level information is used to indicate the content level of a media stream. Multiple content levels can be tagged for the same media stream in an immersive service.

[0367] A mapping list between QoS profiles and Content of Service (CoS) levels indicates adaptive QoS allocation principles.

[0368] A priority list of QoS profiles with CoS levels is used to indicate the adaptive QoS profile.

[0369] In one embodiment, the PCF considers content-based adaptive QoS indications and content-based adaptive QoS auxiliary information as described above to determine the PCC rules.

[0370] In one embodiment, the PCF sends authorized content-based adaptive QoS, CoS level information, a mapping list between QoS profiles and CoS levels, and a priority list of QoS profiles with CoS levels to the second CP NF or SMF via PCC rules.

[0371] In some embodiments, for a second CP NF or SMF:

[0372] Based on the PCC rules from the PCF, the SMF generates and provides the NG-RAN with authorized content-based adaptive QoS, CoS level information, QoS profiles and a mapping list between CoS levels, as well as a priority list of QoS profiles with QoS flow CoS levels.

[0373] In one embodiment, the content-based adaptive QoS profile, CoS level information, mapping list between QoS profile and CoS level, and priority list of QoS profiles with CoS level may be included in the QoS rules provided to the UE for UL data stream transmission, and / or may be included in the PDR, QER, and / or FAR rules provided to the first user plane network element (UP NF) or PSA UPF or service UPF for DL ​​data stream transmission.

[0374] In some embodiments, the second CP NF or SMF instructs the first UP NF or PSA UPF or access UPF or service UPF to execute authorization rules (e.g., FAR, QER, PDR), including a content-based adaptive QoS profile, CoS level information, a mapping list between the QoS profile and the CoS level, and a priority list of QoS profiles with CoS levels. Furthermore, the SMF configures or activates rules to the first UP NF or PSA UPF or access UPF or service UPF (e.g., via an N4 session).

[0375] In some embodiments, for the first UP NF or PSA UPF or access UPF or service UPF:

[0376] The first UP NF, PSA UPF, access UPF, or service UPF detects immersive service data streams and executes authorization rules (e.g., FAR, QER, PDR), including content-based adaptive QoS profiles, service content (CoS) level information, a mapping list between QoS profiles and service content (CoS) levels, and a priority list of QoS profiles with CoS levels.

[0377] In some embodiments, for consumers (such as NG-RAN, access UPF):

[0378] Taking into account the content provided by the second CP NF or SMF, the consumer executes an authorized QoS profile, including a content-based adaptive QoS profile, CoS level information, a mapping list between the QoS profile and the CoS level, and a priority list of QoS profiles with CoS levels, to support content-based adaptive QoS.

[0379] In some embodiments, for the UE (including the UE and / or subsequent devices such as immersive devices or XR devices):

[0380] Taking into account the content provided by the second CP NF or SMF, the UE uses adaptive QoS information to execute authorized QoS rules, including a content-based adaptive QoS profile, CoS level information, a mapping list between the QoS profile and the CoS level, and a priority list of QoS profiles with CoS levels.

[0381] Figure 4 This is an interactive schematic diagram illustrating an exemplary implementation of the communication method provided according to embodiments of this disclosure. For example... Figure 4 As shown, this method involves the establishment process of an AF session with required QoS.

[0382] In step 1, the AF (i.e., the second network element) sends an AF session resource request, for example, by creating an AF request through an Nnef_AFsessionWithQoS_Create request. The AF carries the QoS requirements of the data streams for immersive services (including XR) and interactive media services in the request message.

[0383] In some embodiments, the AF (Immersive Service ASP) provides QoS requirements for media streams to 6G immersive service operation functions (such as PCF, SMF, UPF, service agent), including content-based adaptive QoS indications, CoS level information, a mapping list between QoS profiles and CoS levels, and a priority list of QoS profiles with CoS levels.

[0384] In some embodiments, for content-based adaptive QoS processing, at least one of the following is introduced:

[0385] Content-based adaptive QoS indication to indicate support for content-based adaptive QoS processing.

[0386] CoS level information is used to indicate the content level of a media stream. In one embodiment, the same media stream for an immersive service can be tagged with multiple content levels.

[0387] A mapping list between QoS profiles and CoS levels indicates the adaptive QoS allocation principle.

[0388] A priority list of QoS profiles with CoS levels is used to indicate the adaptive QoS profile.

[0389] In some embodiments, content-based adaptive QoS indications, CoS level information, mapping lists between QoS profiles and CoS levels, and priority lists of QoS profiles with CoS levels may be provided by the application service provider (ASP) of the immersive service, the service agent of the operator in the PCF or PLMN or SNPN, to indicate auxiliary information for content-based adaptive QoS processing enabled in the 6G network.

[0390] In some embodiments, for CoS-level information, different content complexities (e.g., simple content, semi-complex content, complex content) and granularities of media information can be considered for allocation. For example, as described below:

[0391] Simple content refers to media information (e.g., video frames with little frequency or temporal variation (i.e., static or semi-static) or spatial variation (i.e., mostly ordinary)).

[0392] Complex content refers to media information (such as video frames with high dynamic range and rich spatial information).

[0393] Semi-complex content refers to media information that has semi-static temporal and / or spatial information changes, falling between simple and complex content.

[0394] In some embodiments, the AF may provide the above information to the core network (e.g., NEF or PCF) during the AF QoS request / update process.

[0395] In some embodiments, XRM service information is carried, including identification of the XRM service data flow or data flow group (e.g., multi-modal service ID), UE address / UE Identifier, AF IdentifierApplication ID, Flow description(s), DNN, S-NSSAI, QoS parameters, and other relevant information. Here, the multi-modal service ID can be used to identify all flows in the XRM service group.

[0396] In step 2, the NEF (i.e., the fifth network element) authorizes the AF request. If it is an untrusted AF, the NEF sends the AF request to the PCF. (For example, the NEF performs relevant mappings, including mapping the XRM service identifier (AF service identifier) ​​to the DNN and S-NSSAI, mapping the external application to the CN application identifier; and mapping the external UE identifier to the CN UE identifier (such as SUPI) based on the subscription information of unified data management (UDM), and performing the mapping of the external to the internal XRM service group identifier according to the UDM subscription information.)

[0397] In step 3, the NEF authorizes the AF request and determines whether to invoke the 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 an Npcf_PolicyAuthorization_Create request, sending the AF request to the PCF, carrying indications and QoS requirement information for the PCF's policy decision.

[0398] In some embodiments, the message carries an indication of content-based adaptive QoS for the corresponding service data stream, CoS level information, a mapping list between QoS profiles and CoS levels, and a priority list of QoS profiles with CoS levels, to enable and support content-based adaptive QoS.

[0399] In step 4, the PCF (i.e., the first network element) performs a policy decision. In some embodiments, the PCF may determine updated or new policy information, which needs to be sent to the SMF.

[0400] In some embodiments, the first CP NF or PCF or service agent authorizes and provides content-based adaptive QoS for service data flows, as well as other network controls (e.g., in PCC rules) to the SMF regarding the detection, gating, QoS, and charging of service data flows, taking into account:

[0401] Content-based adaptive QoS indication to indicate support for content-based adaptive QoS processing.

[0402] Content-of-Service (CoS) level information is used to indicate the content level of a media stream. Multiple content levels can be tagged for the same media stream in an immersive service.

[0403] A mapping list between QoS profiles and Content of Service (CoS) levels indicates adaptive QoS allocation principles.

[0404] A priority list of QoS profiles with CoS levels is used to indicate the adaptive QoS profile.

[0405] In some embodiments, the PCF considers content-based adaptive QoS indications and content-based adaptive QoS auxiliary information as described above to determine PCC rules.

[0406] In some embodiments, the PCF sends authorized content-based adaptive QoS, CoS level information, a mapping list between QoS profiles and CoS levels, and a priority list of QoS profiles with CoS levels to the second CP NF or SMF via PCC rules.

[0407] In step 5, in response, PCF sends an Npcf_PolicyAuthorization_Create response to NEF.

[0408] In step 6, NEF sends an Nnef_AFsessionWithQoS_Create response message to AF, which carries the result to indicate whether the request has been authorized.

[0409] In step 7, the PCF initiates an SMF policy association modification request (PCC rule) to the SMF (i.e., the third network element).

[0410] In some embodiments, based on PCC rules from the PCF, the SMF generates and provides the NG-RAN with authorized content-based adaptive QoS, CoS level information, a mapping list between QoS profiles and CoS levels, and a priority list of QoS profiles with CoS levels.

[0411] In some embodiments, the content-based adaptive QoS profile, CoS level information, mapping list between QoS profile and CoS level, and priority list of QoS profiles with CoS level may be included in the QoS rules provided to the UE for UL data stream transmission, and / or may be included in the PDR, QER, or FAR rules provided to the first UP NF or PSA UPF or service UPF for DL ​​data stream transmission.

[0412] In some embodiments, the second CP NF or SMF instructs the first UP NF or PSA UPF or service UPF to execute authorization rules (e.g., FAR, QER, PDR), including a content-based adaptive QoS profile, CoS level information, a mapping list between the QoS profile and the CoS level, and a priority list of QoS profiles with CoS levels. Furthermore, the SMF configures or activates rules to the first UP NF or PSA UPF or service UPF (e.g., via an N4 session).

[0413] In step 8, the SMF responds to the PCF with an SM policy association modification response.

[0414] In step 9, the SMF initiates an N4 session modification request to the UPF (i.e., the fourth network element).

[0415] In step 10, the UPF responds to the SMF.

[0416] In some embodiments, the first UP NF or PSA UPF or access UPF or service UPF detects immersive service data streams and executes authorization rules (e.g., FAR, QER, PDR), including a content-based adaptive QoS profile, CoS level information, a mapping list between the QoS profile and the CoS level, and a priority list of QoS profiles with CoS levels.

[0417] In step 11, for the modification of the SMF request, the SMF triggers Namf_Communication_N1N2MessageTransfer([N2 SM information](PDU session identifier, QFI, QoS configuration), N1 SM container).

[0418] In step 12, the AMF (i.e., the sixth network element) can send an N2 message ([N2 SM information received from the SMF], NAS message (PDU session identifier, N1 SM container (PDU session modification command))) to the RAN.

[0419] In step 13, the RAN can perform resource establishment with the UE.

[0420] In step 14, the RAN can acknowledge the N2 PDU session request by sending an N2 PDU session acknowledgment message to the AMF.

[0421] In step 15, the AMF forwards the N2 SM information received from the AN to the SMF through the Nsmf_PDUSession_UpdateSMContext service operation.

[0422] In step 16, SMF responds with the Nsmf_PDUSession_UpdateSMContext response.

[0423] In steps 17 and 18, the SMF can update the N4 session of the UPF involved in the PDU session modification by sending an N4 session modification request message to the UPF.

[0424] In some embodiments, DL immersive service data streams from third-party ASs or proxy ASs in the PLMN, and UL immersive service data streams from UEs or downstream devices.

[0425] In step 9a, taking into account the QoS indication and CoS level information of the content, the first CP NF / PSA UPF / service UPF consumer implements authorized QoS for the downlink immersive service data stream, and the UE implements authorized QoS rules for the uplink immersive service data stream.

[0426] In some embodiments, for consumers (such as NG-RAN, access UPF):

[0427] Taking into account the content provided by the second CP NF or SMF, the consumer executes an authorized QoS profile, including a content-based adaptive QoS profile, CoS level information, a mapping list between the QoS profile and the CoS level, and a priority list of QoS profiles with CoS levels, to support content-based adaptive QoS.

[0428] In some embodiments, for the UE (including the UE and / or subsequent devices such as immersive devices or XR devices):

[0429] Taking into account the content provided by the second CP NF or SMF, the UE uses adaptive QoS information to execute authorized QoS rules, including a content-based adaptive QoS profile, CoS level information, a mapping list between the QoS profile and the CoS level, and a priority list of QoS profiles with CoS levels.

[0430] In some embodiments, step 9a can be performed at any time after step 9.

[0431] In some embodiments, for 6G, particularly immersive services, content-based adaptive QoS processing for immersive services is introduced, including content-based adaptive QoS indication, CoS level information, a mapping list between QoS profiles and CoS levels, a priority list of QoS profiles with CoS levels, and authorization and execution procedures between NFs of the operator network for content-based adaptive QoS, including both the operator network and the data network.

[0432] In some embodiments, content-based adaptive QoS processing for immersive services is introduced to well support the QoS requirements of immersive services (including ultra-high resolution, high frame rate, wide color gamut, high dynamic range, wide field of view and advanced encoding / compression technologies), as well as efficient resource management for 6G communications.

[0433] In some embodiments, other optional implementations of the steps in the communication method shown in this disclosure can be found in [reference needed]. Figure 2 The related parts in the embodiments involved will not be described again here.

[0434] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a microprocessor, and the memory can be internal or external to the device.

For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD), such as a field-programmable gate array (FPGA).

In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an ASIC or PLD, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
