[0130] Here, we will explain the important concepts involved in the disclosed embodiments.

[0131] 1. 6G Use Cases

[0132] Communication technology is evolving from 5G to 6G. In addition to enhancements in system architecture and functionality, 6G communication systems also require support for a wider range of usage scenarios.

[0133] In some embodiments, the proposed use cases for 6G communication technology include: immersive communication, ultra-reliable low-latency communication, massive MIMO, ubiquitous connectivity, integrated intelligent communication, and integrated communication sensing.

[0134] In some embodiments, immersive communication is an extension of enhanced mobile broadband (eMBB) in 5G. Immersive communication covers use cases that provide users with rich, interactive video (immersive) experiences, including interactions with machine interfaces.

[0135] In some embodiments, immersive communication is used in a range of environments, including hotspots, towns, and rural areas, creating additional and new demands compared to eMBB in 5G.

[0136] In some embodiments, typical use cases for immersive communication include immersive extended reality (XR), remote multi-sensory presentation, and holographic communication. Supporting mixed data streams of video, audio, and other environmental data in a time-synchronized manner is an integral part of immersive communication, and also includes independent support for sound.

[0137] In some embodiments, across various environments, the ability to achieve enhanced spectral efficiency and a consistent service experience is critical, along with the need to balance higher data rates and greater mobility. Specific immersive communication use cases requiring responsive and precise interaction with real and virtual objects also need to support high reliability and low latency, as well as large system capacity for simultaneous connections of a large number of devices.

[0138] In some embodiments, the use cases for Hyper-Reliable and Low-Latency Communication (URLLC) extend the use cases of Ultra-Reliable and Low-Latency Communication (URLLC) in 5G. The use cases covered by URLLC are expected to have more stringent requirements in terms of reliability and latency. This is typically used for time synchronization operations, where failure to meet these requirements can lead to serious consequences for the application.

[0139] In some embodiments, typical use cases for ultra-reliable low-latency communication include communications for full automation, control, and operation in industrial environments. These communication types facilitate a variety of applications, such as machine interaction, emergency services, telemedicine, and monitoring of power transmission and distribution.

[0140] In some embodiments, use cases for ultra-reliable low-latency communication may require support for enhanced reliability and low latency, and depending on the use case, may also require precise location and connection density.

[0141] In some embodiments, massive communication is used in 5G for massive machine-type communication (mMTC). Massive communication involves connecting large-scale devices or sensors for a wide range of use cases and applications.

[0142] In some embodiments, typical use cases for large-scale communications include expansion and new applications in smart cities, transportation, logistics, health, energy, environmental monitoring, agriculture, and other areas where various IoT devices, either without batteries or with long-life batteries, are required.

[0143] In some embodiments, large-scale communication use cases may require support for high connection density, and depending on the use case, may also require different data rates, low power consumption, mobility, extended coverage, and high security and reliability.

[0144] In some embodiments, ubiquitous connectivity is used to improve connectivity and, more importantly, to bridge the digital divide. Connectivity can be improved, particularly through interoperability with other systems. A key focus of ubiquitous connectivity use cases is addressing currently uncovered or difficult-to-reach areas, especially rural, remote, and sparsely populated regions.

[0145] In some embodiments, typical use cases for ubiquitous connectivity include, but are not limited to, IoT and mobile broadband communications.

[0146] In some embodiments, the use cases of integrated artificial intelligence and communication can support distributed computing and artificial intelligence (AI) applications. Typical use cases for integrated artificial intelligence and communication include autonomous driving, automated collaboration between devices for assistive medical applications, the transfer of heavy computational operations across devices and networks, and the creation and prediction of digital twins.

[0147] In some embodiments, the use cases of integrated communications intelligence may require support for high regional traffic capacity and high data rates for user experience, as well as low latency and high reliability, depending on the specific use case. Beyond communications, the use cases of integrated communications intelligence are expected to include a range of new capabilities related to the integration of AI and computing functions, including the acquisition, preparation, and processing of data from different sources; distributed AI model training, model sharing, and distributed inference across international mobile telecommunications (IMT) systems; and the orchestration and linking of computing resources.

[0148] In some embodiments, integrated sensing and communication use cases facilitate new applications and services that require sensing capabilities. This helps provide wide-area, multi-dimensional sensing, providing spatial information about unconnected objects and connected devices, as well as their movement and surrounding environment.

[0149] In some embodiments, use cases for integrated communication and sensing include navigation, activity detection and motion tracking (e.g., gesture recognition, fall detection, vehicle / pedestrian detection), environmental monitoring (e.g., rain / pollutant detection), and providing sensing data / information related to the surrounding environment for use in AI, XR, and digital twin applications.

[0150] In some embodiments, along with the provided communication capabilities, the use cases of integrated communication and sensing need to support high-precision positioning and sensing-related capabilities, including range / rate / angle estimation, object and presence detection, positioning, imaging, and mapping.

[0151] It should be noted that each of the 6G use cases described above can also be considered a corresponding type of service. For example, the service in the immersive communication use case can be an immersive communication service. For example, the service in the ultra-reliable low-latency communication use case can be an ultra-reliable low-latency communication service. For example, the service in the massive MIMO use case can be a massive MIMO service. For example, the service in the ubiquitous connectivity use case can be a ubiquitous connectivity service. For example, the service in the integrated intelligent communication use case can be an integrated intelligent communication service. For example, the service in the integrated communication sensing use case can be an integrated communication sensing service.

[0152] 2. Asynchronous communication

[0153] Some communication information transmitted in a communication system may not have strict latency requirements or real-time processing requirements. In order to implement the transmission of this type of communication information in a targeted manner, the concept of asynchronous communication was proposed.

[0154] Asynchronous communication is designed to meet the service and communication requirements of communication systems. Asynchronous communication can be understood as a mechanism, feature, or function. It involves delaying the transmission of communication information. In some embodiments, when using asynchronous communication, the communication system, particularly the core network, can delay the transmission of communication information.

[0155] In some embodiments, when using an asynchronous communication mechanism, the core network can store or buffer the communication information after acquiring it, and then transfer or synchronize the stored or buffered information at an appropriate time. For example, communication information from a specific network function to a terminal can use an asynchronous communication mechanism, where the communication information from the network function can be stored in the core network after arriving at the core network, and the core network transmits the communication information to the terminal at an appropriate time. Similarly, communication information from one network function to another can use an asynchronous communication mechanism, where the communication information from the former can be stored in the core network after arriving at the core network, and the core network transmits the communication information to the latter at an appropriate time. Thus, the asynchronous communication mechanism enables delayed transmission of communication information.

[0156] In some embodiments, asynchronous communication may target signaling and / or data. In one example, asynchronous communication may be applied to the transmission of signaling. In another example, asynchronous communication may be applied to the transmission of data.

[0157] Based on the above, how communication networks can support asynchronous communication is a problem that needs to be solved.

[0158] Figure 3 is an interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in this embodiment can be applied to a communication system 100. As shown in Figure 3, the communication method of this embodiment includes steps S301 to S307.

[0159] In some embodiments, the communication system 100 may refer to the system architecture shown in FIG2.

[0160] In some embodiments, this disclosure relates to a first node 101, a second node 102, and a third node 103. In some embodiments, the first node 101 may be one of DNF, ASP, or AF. In some embodiments, the second node 102 may be at least one of PCF, SMF, and AMF. In one example, the second node 102a is PCF, the second node 102b is SMF, and the second node 102c is AMF. In some embodiments, the third node 103 may be UPF. It should be noted that the first node 101, the second node 102, and the third node 103 may also be other network functions, and this disclosure does not specifically limit them.

[0161] In step S301, the first node 101 sends the first information to the second node 102a.

[0162] In some embodiments, the first node 101 may send first information. In some embodiments, the first information may be sent by the first node 101, but is not limited thereto, and may also be sent by other entities.

In some embodiments, the data may be data from a first service employing asynchronous communication. For example, the data may include data from at least one of the user plane and the data plane.

[0167] In some embodiments, storing service information may include storing signaling and / or data. In one example, the second node 102 may have the capability to store signaling and / or data provided to network functions (such as 6GC NF) and / or terminals. In one example, in asynchronous communication, the second node 102 may store signaling and / or data provided to network functions (such as 6GC NF) and / or terminals.

[0168] In some embodiments, transmitting service information may include transmitting signaling and / or data. In one example, the second node 102 may have the capability to trigger the transmission or synchronization of signaling and / or data to network functions (such as 6GC NF) and / or terminals. In one example, in asynchronous communication, the second node 102 may transmit or synchronize signaling and / or data to network functions (such as 6GC NF) and / or terminals.

In one embodiment, the service type of the first service may include at least one of the following: immersive communication, ultra-reliable low-latency communication, massive MIMO, ubiquitous connectivity, integrated intelligent communication, and integrated communication sensing.

[0170] In some embodiments, the name of the first information is not specifically limited, but may be, for example, indication information, asynchronous type communication indication information, service indication information, etc.

[0171] In some embodiments, when the first node 101 establishes a session for a first service request, it sends first information to the second node 102a. In one embodiment, the first information may be carried in a QoS request message. In another embodiment, the first information may be carried in a QoS update message. In one example, the first node 101 is an AF (Active Message Server), and the first information may be carried in a session request message (such as Nnef_AFsessionWithQoS_Create request) to request the establishment of a session for the first service.

[0172] In some embodiments, the first information is used to indicate a delay in transmitting service information of the first service. In one embodiment, the first information is used to indicate that the core network delays transmitting service information of the first service with other network elements and / or terminals. In one example, the second node 102 and the third node 103 are deployed in the 6GC, and the first information can be used to indicate that the 6GC delays transmitting service information of the first service with the NF and / or UE. In one example, the first information from the first node 101 can be an asynchronous type communication support indication.

[0173] In some embodiments, the first information is further used to indicate that the communication system 100 where the second node 102 is located supports asynchronous communication. In some embodiments, the first information is further used to indicate that the communication system 100 where the second node 102 is located needs to support asynchronous communication. In some embodiments, the first information is further used to indicate that the communication system 100 where the second node 102 is located needs to support asynchronous communication. In one example, the second node 102 and the third node 103 are deployed in a 6GC, and the first information is further used to indicate that the 6GC supports asynchronous communication. In one example, the second node 102 and the third node 103 are deployed in a 6GC, and the first information is further used to indicate that the 6GC NF and / or UE support asynchronous communication.

[0174] In some embodiments, the first node 101 may also send second information to the second node 102a. This second information is used to assist the second node 102 in processing the first service's business information. In one embodiment, the second information may be carried in the same message (e.g., a session resource request message) as the first information and sent by the first node 101 to the second node 102a. In one embodiment, the second information may be carried in different messages as the first information and sent simultaneously by the first node 101 to the second node 102a. In another embodiment, the second information may be carried in different messages as the first information and sent separately by the first node 101 to the second node 102a.

[0175] In some embodiments, the second information is used to assist the second node 102 in making policy decisions. In one example, the second node 102 may consider the second information to determine whether to adopt asynchronous communication for the first service. In one example, the second node 102 may consider the second information to determine the NF used for adopting asynchronous communication. In one example, the second node 102 may consider the second information to determine the functionality and / or function-related configuration of asynchronous communication.

[0176] In one embodiment, the function of asynchronous communication may include at least one of the following: storing service information, transmitting service information, and triggering the transmission of service information. In one example, configurations related to the storage of service information may include: a time window for storing data, a maximum amount of data to be stored, the type of data to be stored, the type of storage signaling, the source of the stored data, and the function of the storage signaling. In one example, configurations related to the transmission of service information may include: QoS configuration, the number of terminals transmitting service information, and the number of sessions transmitting service information.

[0177] In some embodiments, the second information may indicate at least one of the following: QoS requirement information, service type information, and first protocol description information.

[0178] In some embodiments, QoS requirement information is used to indicate the QoS requirements associated with the data flow of the first service. In one embodiment, the QoS requirement may be a QoS configuration that the first node 101 expects the data flow of the first service to meet. In one example, the QoS requirement information may include at least one of the following QoS parameters: guaranteed flow bit rate (GFBR), maximum flow bit rate (MFBR), and maximum packet loss rate.

In one embodiment, the service type may indicate at least one of the following: immersive communication, ultra-reliable low-latency communication, massive MIMO, ubiquitous connectivity, integrated intelligent communication, and integrated communication sensing.

[0180] In some embodiments, service type information may also be associated with subtypes within each of the aforementioned service types. In one example, for immersive communication, service type information may further indicate one or more services such as XR, remote multi-sensory presentation, and holographic systems. In one example, for ultra-reliable low-latency communication, XR may further indicate one or more services such as machine interaction, emergency services, and telemedicine. In one example, for large-scale communication, service type information may further indicate one or more services such as machine interaction, emergency services, and telemedicine.

[0183] In some embodiments, QoS configuration information is used to indicate the QoS profile associated with the first service. In one embodiment, the QoS profile associated with the first service may be a QoS profile configured by the first node 101 for the first service. These QoS profiles can be used by the second node 102a to generate corresponding policies for the first service, so as to realize QoS control of the service information of the first service.

[0184] In some embodiments, priority information is used to indicate the priority of the QoS profile associated with the first service. In one embodiment, for the same service type, the first service can be configured with multiple QoS profiles, and the different QoS profiles have different priorities. Therefore, the priority information can indicate the priority of the multiple QoS profiles associated with the first service.

[0185] In some embodiments, the priority of the QoS profile associated with the first service can be related to the service type. In some embodiments, for different service types, the first service can be configured with one or more QoS profiles, which can have the same or different priorities. For example, the priority of the first service type is higher than the priority of the second service. Then, the second node 102 can preferentially select the QoS profile associated with the first service type during asynchronous communication. In one embodiment, the first service type can be one of immersive communication, ultra-reliable low-latency communication, massive communication, ubiquitous connectivity, integrated intelligent communication, and integrated communication sensing, and the second service type can be another service type among immersive communication, ultra-reliable low-latency communication, massive communication, ubiquitous connectivity, integrated intelligent communication, and integrated communication sensing.

[0186] In some embodiments, the second protocol description information is used to indicate the protocols that asynchronous communication needs to support. In one embodiment, the protocols that asynchronous communication needs to support can be protocols that the second node 102 needs to support during the processing of asynchronous communication. In one embodiment, the protocol indicated by the second protocol description information can be associated with the function of asynchronous communication. In some embodiments, the function of asynchronous communication can include at least one of storing service information, transmitting service information, and triggering the next node to transmit service information. For different functions, the second node 102 may need to support different protocols. In one example, for immersive communication, transmitting service information has a higher priority than storing service information; in this case, the second node 102 can prioritize supporting the transmission protocol. In one example, for ultra-reliable low-latency communication, storing service information has a higher priority than transmitting service information; in this case, the second node 102 can prioritize supporting the storage protocol.

[0187] In some embodiments, the first capability requirement information is used to indicate the capabilities that asynchronous communication needs to support. In one embodiment, the capabilities that asynchronous communication needs to support may be functions that the first node 101 expects the second node 102 to support, such as at least one of the asynchronous communication functions described above. In one embodiment, the capabilities that asynchronous communication needs to support may include requirements related to the functions that the first node 101 expects the second node 102 to support, such as requirements for storage period, transmission rate, transmission time, transmission triggering events, etc. In one embodiment, the capabilities that asynchronous communication needs to support may include information related to the functions that the first node 101 expects the second node 102 to support, and this related information is used to implement the corresponding asynchronous communication functions.

[0188] In some embodiments, the second capability requirement information is used to indicate the capabilities that the first service needs to support. In one embodiment, the capabilities that the first service needs to support may be functions of the first service that the first node 101 expects the second node 102 to support, such as at least one of the functions of the asynchronous communication described above. In one embodiment, the capabilities that the first service needs to support may include requirements related to the functions of the first service that the first node 101 expects the second node 102 to support, such as storage period, transmission rate, transmission time, transmission triggering event, etc. In one embodiment, the capabilities that the first service needs to support may include information related to the functions of the first service that the first node 101 expects the second node 102 to support, and this related information is used to implement the functions of the corresponding first service.

[0189] In some embodiments, the third capability requirement information is used to indicate the capabilities that the communication system (e.g., communication system 100) where the second node 102 resides needs to support. In one embodiment, the capabilities that communication system 100 needs to support may include the functionality that the first node 101 expects communication system 100 to support, such as at least one of the asynchronous communication functions described above. In one embodiment, the capabilities that communication system 100 needs to support may include requirements related to the asynchronous communication functionality that the first node 101 expects communication system 100 to support, such as storage period, transmission rate, transmission time, transmission triggering event, etc. In one embodiment, the capabilities that communication system 100 needs to support may include information related to the asynchronous communication functionality that the first node 101 expects communication system 101 to support, and this related information is used to implement the corresponding asynchronous communication functionality.

[0190] In some embodiments, the capabilities that the communication system 100 needs to support may refer to the capabilities that each node in the communication system 100 needs to support. In some embodiments, the capabilities that the communication system 100 needs to support may refer to the capabilities that each core network NF in the communication system 100 needs to support.

[0191] In some embodiments, the second information can be determined by at least one of the following methods: protocol-defined, OAM configuration, operator configuration, local configuration, etc. In this case, the first node 101 may not send the second information to the second node 102. In other words, the step of the first node 101 sending the second information to the second node 102a can be omitted.

[0192] In step S302, the second node 102a determines strategy A.

[0193] In some embodiments, after receiving the first information, the second node 102a can determine strategy A for the first service. In this case, the first strategy is strategy A.

[0291] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0292] In this embodiment of the disclosure, in order to realize 6G massive data processing, it is recommended to support asynchronous communication, especially service data (or communication information) that does not have critical latency requirements or immediate processing requirements.

[0293] In some embodiments, the DN / ASP / AF (such as the first node 101): The DN / ASP / AF provides an asynchronous type communication support indication to the core network (CN) (PCF / NEF / proxy AF). Optionally, it provides the CN with the QoS requirements, service type, and protocol description of the media stream to assist service processing (e.g., policy determination, application ATC functions).

[0294] In some embodiments, asynchronous type communication support indicates that the 6GC delay is synchronized with the NF or UE for service signaling and / or service data.

[0295] In some embodiments, support for asynchronous type communication is optional for 6GS (e.g., 6GC NF and UE).

[0296] In some embodiments, the service type includes one or more of the following:

[0297] Immersive communication;

[0298] Ultra-reliable and low-latency communication;

[0299] Massive communication;

[0300] Ubiquitous connectivity;

[0301] Integrated intelligent communication;

[0302] Communication and sensing integration.

[0303] In some embodiments, 6GC supports asynchronous communication, including at least one of the following features:

[0304] The ability to store service signaling and / or service data provided to the NF or UE;

[0305] The ability to trigger service signaling and / or service data to be transmitted / synchronized to the forwarding NF or UE.

[0306] In some embodiments, the CN is provided with the QoS requirements, service type, and protocol description of the media stream to assist service processing (e.g., policy determination, application ATC characteristics), and further provides one or more of the following:

[0307] Different QoS profiles and priorities for different service types;

[0308] The protocol or capability that enables ATC functionality;

[0309] The business or system capabilities required by AF (e.g., application ATC function, ATC data storage, ATC signal storage).

[0310] In some embodiments, the DN / ASP / AF provides an asynchronous type communication support indication to the CN (PCF / NEF / Proxy AF) during the AF QoS request / update process.

[0311] In some embodiments, the first CP NF / (PCF / NEF) / agent AF (e.g., the second node 102a): The first CP NF / (PCF / NEF) / considers the asynchronous type communication support indication and performs policy determination and authorization. The first CP NF / (PCF / NEF) / determines the PCC rules based on the asynchronous type communication support indication. The first CP NF / (PCF / NEF) / sends the authorized PCC rules to the second CP NF / (SMF).

[0312] In some embodiments, the second CP NF / SMF (e.g., second node 102b): Based on the PCC rules from the PCF, the SMF generates and provides a QoS profile with authorized QoS parameters to the NG-RAN and / or UPF. The SMF instructs the UPF to execute the authorized QoS. Furthermore, the SMF configures / activates rules (including PDRs) to the UPF (e.g., via an N4 session). The SMF sends the QoS profile with authorized QoS parameters to the consumer NF (e.g., RAN) for QoS tuning or QoS enforcement.

[0313] In some embodiments, the first UP NF / UPF (such as the third node 103): The first UP NF / UPF performs authorized QoS, taking into account asynchronous type communication to support the required services.

[0314] Figure 5 is an interactive schematic diagram of an exemplary implementation of the communication method provided according to embodiments of the present disclosure. This implementation relates to the AF session establishment or modification process. As shown in Figure 5, the communication method includes steps S501 to S517.

[0315] In step S501, the AF issues an AF dialogue resource request.

[0316] In some embodiments, the AF creates an AF request via an Nnef_AFsessionWithQoS_Create request. The AF carries the requested service and data flow QoS requirements in the request message.

[0317] In some embodiments, the DN / ASP / AF provides the CN (PCF / NEF / Proxy AF) with an indication of asynchronous type communication support. Optionally, the QoS requirements, service type, and protocol description of the media stream are provided to the CN to assist service processing (e.g., policy determination, application ATC functions).

[0318] In some embodiments, asynchronous type communication support indicates that the 6GC delay is synchronized with the NF or UE for service signaling and / or service data.

[0319] In some embodiments, support for asynchronous type communication is optional for 6GS (e.g., 6GC NF and UE).

[0320] In some embodiments, the service type includes one or more of the following:

[0321] Immersive communication;

[0322] Ultra-reliable and low-latency communication;

[0323] Massive communication;

[0324] Ubiquitous connectivity;

[0325] Integrated sensor communication;

[0326] Integrated sensing communication.

[0327] In some embodiments, 6GC supports asynchronous communication, including at least one of the following features:

[0328] The ability to store service signaling and / or service data provided to the NF or UE;

[0329] The ability to trigger service signaling and / or service data to be transmitted / synchronized to the forwarding NF or UE.

[0330] In some embodiments, the QoS requirements, service type, and protocol description of the media stream are provided to the CN to assist in service processing (e.g., policy determination, application ATC functionality), including one or more of the following:

[0331] Different QoS profiles and priorities for different service types;

[0332] Protocols or capabilities that utilize ATC functionality;

[0333] The services or system capabilities required by AF (e.g., ATC function applications, ATC data storage, ATC signal storage).

[0334] In some embodiments, the DN / ASP / AF provides an asynchronous type communication support indication to the CN (PCF / NEF / Proxy AF) during the AF QoS request / update process.

[0335] In step S502, NEF authorizes the AF request. If the AF is unacceptable, the AF request is sent through NEF. If 6GS supports Agent AF within the PLMN, it is used to proxy business requests and process requests from third-party AFs or ASs within the PLMN. NEF issues the current ATC function request, and the location where NEF issues the corresponding request can be selected as the Agent AF executor ATC function.

[0336] In step S503, NEF issues an Npcf_Policy Authorization_Create request, sends the AF request to PCF, and provides QoS request information. The PCF policy information center should provide asynchronous type communication support indication and service QoS requirements and auxiliary information provided by AF.

[0337] In step S504, the PCF makes a policy decision. The PCF may determine that updated or new policy information needs to be sent to the SMF.

[0338] In some embodiments, the first CP NF / (PCF / NEF) / considers asynchronous type communication support indications for policy determination and authorization.

[0339] In some embodiments, the first CP NF / (PCF / NEF) / considers asynchronous type communication support indications to determine PCC rules. The first CP NF / (PCF / NEF) / sends the authorized PCC rules to the second CP NF / (SMF).

[0340] In step S505, the PCF sends an Npcf_Policy Authorization_Create response to the NEF.

[0341] In step S506, NEF sends an Nnef_AFsessionWithQoS_Create response message to AF to inform whether authorization is requested.

[0342] In step S507, the PCF initiates an SM policy association modification request (PCC rule) to the SMF.

[0343] In some embodiments, based on PCC rules from the PCF, the SMF generates and provides a QoS profile with authorized QoS parameters to the NG-RAN and / or UPF.

[0344] In some embodiments, the SMF instructs the UPF to perform authorized QoS. Additionally, the SMF configures / activates rules (including PDRs) for the UPF (e.g., via an N4 session).

[0345] In some embodiments, the SMF sends a QoS profile with authorized QoS parameters to the consumer NF (e.g., RAN) for QoS adjustment or QoS implementation.

[0346] In step S508, the SMF replies to the PCF with an SM policy association modification response.

[0347] In step S509, the SMF initiates an N4 session modification request to the UPF.

[0348] In step S510, the UPF responds to the SMF.

[0349] In some embodiments, the first UP NF / UPF performs authorized QoS, taking into account asynchronous communication types to support the required services.

[0350] In step S511, for the modification of the SMF request, the SMF calls Namf_Communication_N1N2MessageTransfer([N2SM information](PDU session ID, QFI, QoS configuration file), N1 SM container).

[0351] In step S512, AMF can send N2 ([N2 is the SM information received from SMF]) and NAS message (PDU session ID, N1 SM container (PDU session modification command)) to (R)AN.

[0352] In step S513, (R)AN can confirm the N2 PDU session request by sending an N2 PDU session confirmation message to the AMF.
