Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, apparatus and device for collaborative communication between a short-range communication network and a cellular network. Background Art

[0002] In the 5G wireless communication system, 3GPP R16 defines non-3GPP access (Non-3GPP Access). By defining the Trusted Non-3GPP Gateway Function (TNGF) and the Non-3GPP InterWorking Function (N3IWF), non-3GPP networks can access the 5G Core Network (5GC). The 5G Core Network will perform unified authentication, billing, and mobility management, for example, unified management of factory site equipment.

[0003] For 3GPP networks, non-3GPP access networks can support interfaces with 5GC networks, enabling wireless devices to connect to these mobile networks and utilize their services. The two main architectures available are the TNGF architecture and the N3IWF architecture. However, the N3IWF architecture only involves UE registration and identity authentication, and 5GC does not provide short-range Quality of Service (QoS) scheduling policies. The current TNGF architecture does not clearly define the specific functions and interaction processes of the AAA interface.

[0004] Therefore, how to coordinate short-range technology and cellular network technology to optimize the efficiency of heterogeneous networks in the network session link establishment process is the key foundation for promoting the development of heterogeneous network convergence technology.

[0145] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0146] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0147] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0148] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0149] In the embodiments provided herein, it should be understood that "B corresponding to A" means that B is associated with A and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B based solely on A; B can also be determined based on A and / or other information.

[0150] When describing the embodiments of the present invention, some concepts used in the following description are first explained.

[0151] Transmission between nodes can be divided into pure control signaling, data control signaling, and data flow. Pure control signaling mainly includes negotiation, connection, encryption and decryption, and signaling for interaction with the application layer in addition to data. According to the complete interaction process of end-to-end communication, pure control signaling is mainly concentrated in the stages of device discovery and service reading. During this period, the heavy signaling interaction process not only increases the load on the 5G cellular network, but also leads to potential signaling storm problems. Therefore, during the communication process of the operator-deployed 5GC requested by the terminal to access the terminal through the 5G Residential Gateway (5G-RG), consideration should be given to simplifying and merging redundant link establishment processes to improve data transmission efficiency.

[0152] Non-3GPP networks accessing the 5G core network can adopt the N3IWF architecture that supports untrusted access. However, 5GC will have difficulty providing QoS scheduling strategies and will not meet the multi-domain collaboration and multi-service concurrent transmission requirements of industry sites. Therefore, the TNGF architecture with trusted access to 5GC is preferred.

[0153] The communication process between the terminal, the Radio Access Network (RAN) and the core network is as follows: Figure 1 As shown, it includes three stages: device discovery, service reading and data transmission. Among them, the device discovery stage includes the device discovery process and the connection establishment process; the service reading stage includes: the service reading process and the capability information interaction process; the data transmission stage includes: the data stream transmission process.

[0154] like Figure 2 As shown, an embodiment of the present invention provides a collaborative communication method between a short-range communication network and a cellular network, which is applied to a convergence node, including:

[0155] Step 21: receiving an admission control request message sent by a terminal via a short-distance communication network, wherein the admission control request message is used to indicate a data flow transmission strategy and / or to negotiate a data flow diversion strategy.

[0156] In this embodiment, the terminal is a terminal node (T-Node), and the aggregation node (G-Node) can be a trusted non-3GPP access point (TNAP). The terminal can send data streams to the aggregation node via a short-range communication network. The short-range communication network introduces channel coding and decoding technology Polar and reference signal (RS) to optimize for random interference and burst interference, achieving highly reliable transmission in complex electromagnetic environments.

[0157] The aggregation node can act as a routing / bridging node to connect the terminal node with the 5G network, receive data from the terminal node through the short-range communication network, and send the data to the 5G access gateway.

[0158] This embodiment introduces admission control in the short-range communication domain. By indicating the data flow transmission strategy and / or negotiating the data flow diversion strategy through admission control requests, it can enhance the access negotiation capability of trusted nodes (such as TNAP nodes), improve the negotiation efficiency of heterogeneous non-3GPP networks, simplify or merge pure signaling interactions before data flow transmission, and improve link establishment efficiency.

[0159] Step 22: Perform PLMN search according to the admission control request message to determine the access gateway function of the cellular network.

[0160] Among them, the access gateway function can be a trusted non-3GPP access gateway (i.e. TNGF). The access gateway function connects the aggregation node of short-distance communication through the 5G network, supports the selection of gateway nodes for 5G trusted access, and realizes unified configuration and maintenance of the transmission pipeline.

[0161] In this embodiment, the aggregation node introduces a relay node retrieval mechanism in the protocol data unit (PDU) session established between the aggregation node and the TNGF. The aggregation node acts as a relay node to implement more efficient routing retrieval for 5G converged services in the network session for multi-domain collaborative scenarios that may exist in the industry network, thereby reducing the load on the 5G network.

[0162] Step 23: Establish a session connection between the aggregation node and the access gateway function; wherein the session connection is used for the terminal to transmit data with the core network deployed by the operator requested by the terminal through the aggregation node and the access gateway function.

[0163] A session connection is established between the aggregation node and the access gateway function, and the terminal can communicate with the core network deployed by the operator requested by the terminal through the session connection. This embodiment provides IoT industry terminals with access to the 5GC deployed by the operator requested by the terminal through an aggregation node (such as 5G-RG), realizing coordinated transmission between non-3GPP short-range communication networks and cellular networks, and optimizing network session link establishment efficiency and link robustness.

[0164] While maintaining forward compatibility with existing cellular network protocols, embodiments of the present invention introduce admission control in the non-3GPP short-range communication domain. This enhances the access negotiation capabilities of trusted nodes, improves the efficiency of heterogeneous network negotiation, simplifies or consolidates the pure signaling interaction process before data stream transmission, and avoids unnecessary link establishment overhead. Furthermore, by introducing a relay node retrieval mechanism for 5G converged services, more efficient trusted node detection is achieved, reducing the load on the 5G network.

[0165] Taking the terminal as T-Node, the aggregation node as TNAP, the access gateway function as TNGF, and the core network as Access and Mobility Management Function (AMF) as an example, the collaborative communication method between the short-range communication network and the cellular network in the embodiment of the present invention is as follows: Figure 3 shown.

[0166] In step 0, admission control is introduced between the T-Node and the TNAP. The admission control request message can be used to indicate: a data flow transmission strategy and / or to negotiate a data flow diversion strategy.

[0167] T-Node sends data streams to the aggregation node through the short-range communication network. The short-range communication network introduces the channel coding and decoding technologies Polar and RS to optimize random interference and burst interference, achieving highly reliable transmission in complex electromagnetic environments.

[0168] Step 1: Perform device discovery process.

[0169] Step 2: Execute the retrieval TNAP service to read the PLMN list and trusted connections.

[0170] Step 3: Execute data transmission, wherein negotiation information such as QoS / Quality of Experience (QoE) may be carried for data transmission.

[0171] Among them, AMF is a core network element used to receive data forwarded by 5G base stations. Based on remote connections, it supports the business interaction of 5G application functions and implements the following functions: (1) registration management of GT nodes (aggregation nodes and terminal nodes); (2) security management between short-range communication domains and core networks; (3) QoS policy configuration; (4) status management of GT nodes (for example, measurement reporting).

[0172] This embodiment maintains its continuity with the 3GPP protocol, continuing the industry-recognized basic logical architecture while addressing the shortcomings of existing technical solutions, providing a practical and innovative solution for industry-oriented virtual private networks. The core network modification cost is low. Simply by enhancing the access negotiation capabilities of trusted nodes based on the existing interaction process and simplifying some of the interaction processes before data stream transmission, the efficiency of heterogeneous non-3GPP network link establishment and the robustness of communication links can be improved, significantly reducing the load on the cellular network.

[0173] The following describes a specific implementation process of the method for cooperative communication between a short-range communication network and a cellular network according to an embodiment of the present invention.

[0174] Optionally, the admission control request message may be a Layer 2 (L2) connection request message; the Layer 2 connection request message includes a target identification field, and the target identification field includes relevant information about the QoS management event. The admission control request message includes relevant information about a Quality of Service (QoS) management event; the relevant information about the QoS management event is used to indicate the QoS requirements of the terminal.

[0175] In this embodiment, the target identification field is a newly added identification field in the layer 2 connection request message, which is used to indicate QoS management events, identify business characteristics and user requirements of different applications and scenarios, and map business characteristics and user requirements into QoS requirements to provide QoS flow data transmission status.

[0176] Taking the relevant information of the QoS management event as an example, the service type (AID), different QoS transmission types (XQI) supported by the bottom layer, routing indication (Port), and basic service layer channel number (TCID) are included. Figure 3 As shown, relevant parameters of QoS management events such as XQI, AID, Port, TCID, etc. are added to the data packet header to support rate adjustment applications to negotiate network resource scheduling. For example, when the channel is congested or the rate cannot be guaranteed, the data rate can be reduced.

[0177] Service Type (AID): For example, HD audio streaming, UHD audio streaming, HD video streaming, best effort data transmission, etc. Each application identifies the AID of the required transmission service based on its own usage scenario, representing the current application's requirement for transmission capabilities.

[0178] Routing indication (Port): the indication of the actual service flow application layer entity.

[0179] Basic service layer channel ID (TCID): used to distinguish basic service layer service data packets with different QoS characteristics.

[0180] As an optional embodiment, performing PLMN retrieval according to the admission control request message to determine the access gateway function of the cellular network includes:

[0181] Retrieve a list of public land mobile networks (PLMNs) supported by the aggregation node according to the admission control request message; determine an access gateway function corresponding to the operator requested by the terminal according to the PLMN list, and configure a trusted connection of the aggregation node.

[0182] In this embodiment, the admission control request message includes relevant information of the QoS management event. The convergence node retrieves the PLMN List according to the admission control request message and detects whether the current high-priority PLMN is invalid, and configures all trusted connections in the domain.

[0183] The PLMN List may be a trusted PLMN list supported by the aggregation node (e.g., TNAP), and the PLMN List includes identification information of one or more operators. After retrieving the PLMN list, the aggregation node configures all trusted connections and determines the access gateway function corresponding to the operator requested by the terminal.

[0184] Optionally, the method further includes: monitoring data flow quality and routing negotiation status between network nodes through the first interface; and adjusting the data transmission rate according to the data flow quality and the routing negotiation status.

[0185] The first interface may be an AAA interface, i.e., a communication interface between the aggregation node and the access gateway function. The aggregation node can monitor data flow quality and routing negotiation between network nodes through the AAA interface. Combined with the relevant information about QoS management events included in the admission control request message, the aggregation node can negotiate network resource scheduling for applications that support rate adjustment and adjust the data transmission rate in a timely manner. For example, if channel congestion or unguaranteed rate is detected, the data rate can be reduced. This enhances the access negotiation capabilities of trusted nodes, improves the efficiency of heterogeneous non-3GPP network link establishment and the robustness of communication links, and significantly reduces the load on the cellular network.

[0186] Optionally, after establishing a session connection between the aggregation node and the access gateway function, the method further includes: adopting a message diversion mechanism based on a session identifier provided by the first interface, and adopting a differentiated transmission strategy to divert and transmit data according to the mapping relationship indicated by the wireless frame.

[0187] In this embodiment, during the interaction between the aggregation node (such as TNAP) and the access gateway function (TNGF), the session identifier-based message diversion mechanism provided by the AAA interface ensures that the routing information is complete or incomplete, and the routing detection of the monitoring event is triggered according to the mapping relationship indicated by the wireless frame to ensure the autonomous discovery and configuration of short-distance and TNGF peer services.

[0188] It should be noted that when the proximal network is densely deployed, there are multiple coexisting trusted AP nodes (such as multiple TNAP nodes). For example, there are 5 nodes, AP0 to AP4, as shown in Table 1. Different nodes correspond to different functions and session identifiers. These AP nodes can use differentiated transmission strategies to divert data through wireless frame indications corresponding to message content, providing QoS flow data transmission.

[0191] Optionally, after receiving the admission control request message sent by the terminal through the short-range communication network, the method further includes:

[0192] An Extensible Authentication Protocol (EAP) request message is sent to a terminal, where the EAP request message is used to request identity information of the terminal; and an EAP response message is received from the terminal, where the EAP response message includes the identity information of the terminal.

[0193] In this embodiment, after the terminal establishes a connection with the aggregation node, the aggregation node, acting as an access point, may request the terminal's identity information from the terminal through an Extensible Authentication Protocol (EAP) process. The terminal then feeds back a response message to the aggregation node, which includes the terminal's identity information, which can be used for identity authentication. The aggregation node's feedback response message may also carry identification information of the operator requested by the terminal, and the aggregation node may determine the cellular network to which the terminal is connected based on the operator's identification information.

[0194] Optionally, the method also includes: receiving feedback information of the QoS management event sent by the access gateway function through the first interface, the feedback information including the QoS policy information configured by the core network; providing the QoS policy information to the access layer for resource scheduling and / or management of the media stream transmission channel.

[0195] After the aggregation node establishes a session connection with the access gateway function, the terminal communicates with the core network deployed by the operator requested by the terminal through the session connection. The access gateway function performs AMF selection, and after determining the AMF in the core network deployed by the operator requested by the terminal, sends an N2 message to the AMF through the N2 interface. The N2 interface is the communication interface between the access gateway function and the AMF. The AMF feeds back an N2 message to the access gateway function through the N2 interface. The fed-back N2 message can carry QoS policy information configured by the core network. The QoS policy information can provide a reference for resource allocation for the non-3GPP network nodes (i.e., the aggregation node and the access gateway function) to which it belongs, so as to enhance the robustness of the communication chain between the terminal and the access gateway function.

[0196] In this embodiment, the MSG message sent by the AMF to the TNGF through the N2 interface is newly added with the QoS policy sent by the core network as a global QoS policy, which provides a reference for resource allocation for the G-Node and T-Node in the non-3GPP network to which it belongs, so as to make real-time adjustments to the global optimality according to the environment. Among them, a sub-session carries a clear QoS service, and the service may occur simultaneously or continuously (for example, voice generated at the same time and data transmitted in the same session). Such sessions are tracked by the radio frame indication (Accounting Sub-Session Id, ASSI) of the sub-session message, and the QoS management will be notified when the transmission fails to meet the QoS flow.

[0197] The aggregation node interacts with the access gateway function through the AAA interface to receive feedback on QoS management events. The aggregation node can provide the QoS policy information to the access layer resource scheduling, or register and monitor events to manage the media stream transmission channel, such as the establishment, configuration, interruption, recovery, and release of logical flows.

[0198] In this embodiment, the MSG message sent by the core network to the TNGF newly carries a global QoS policy indication to provide a reference for resource allocation for the non-3GPP network nodes to enhance the robustness of the communication chain between the terminal and the access gateway function.

[0199] The following describes the implementation process of the collaborative communication method between the short-range communication network and the cellular network of the present invention through a specific embodiment, taking the terminal as T-Node, the aggregation node as TNAP, the access gateway function as TNGF, and the core network as AMF as an example. Figure 4 As shown, including:

[0202] Step 2: TNAP sends an EAP request message to the T-Node to request the terminal's identity information.

[0203] Step 3: The T-Node feeds back an EAP response message to the TNAP. The EAP response message carries the identity information of the terminal, such as the user name.

[0204] The TNAP retrieves the trusted connection of the TNAP through the AAA interface, configures all the diversion paths in the domain, and determines the TNGF for accessing the cellular network.

[0205] Step 4: TNGF sends an EAP request to the T-Node.

[0206] Step 5: T-Node sends parameter information to TNGF through EAP response or 5G-non-access stratum (NAS) or access network (AN) params parameter or NAS-PDU. The parameter information includes: terminal identification (UE ID), PLMN ID, network slice selection assistance information (NSSAI) request, establishment cause, etc., where NAS-PDU can carry a registration request.

[0207] Step 6a: TNGF performs AMF selection and determines the AMF deployed by the operator requested by the T-Node.

[0208] Step 6b: TNGF sends a msg message (which may carry the registration request) to AMF through the N2 interface.

[0209] Step 7a: The AMF sends a msg message to the TNGF via the N2 interface. The msg message may include a Security Mode Command (SMC) request, and carries the QoS policy information configured by the core network.

[0210] Step 7b: The TNGF sends an L2 message to the T-Node, where the L2 message carries the SMC request. The TNGF may send the L2 message via an EAP request or 5G-NAS or NAS-PDU.

[0211] Step 7c: The T-Node feeds back an L2 response message to the TNGF, the L2 response message carrying an SMC completion message, wherein the T-Node may feed back the L2 response message via an EAP response or a 5G-NAS or NAS-PDU. The SMC completion message carries QoS parameters.

[0212] Step 7d: The TNGF feeds back an SMG message to the AMF through the N2 interface, where the SMG message includes an SMC completion message.

[0213] Step 8a: AMF sends an initial context setup request (N2 initial Ctx setuprequest) to TNGF through the N2 interface, including the TNGF key (Key).

[0214] Step 8b: TNGF sends an L2 message to T-Node, which can be an EAP request or a 5G-Notification (notification message).

[0215] Step 8c: The T-Node feeds back an L2 response message to the TNGF, which can be an EAP response or a 5G-Notification.

[0216] Step 8d: TNGF interacts with TNAP through the AAA interface to provide feedback on QoS events, such as an EAP-Success response message.

[0217] Step 8e: TNAP sends an L2 message to the T-Node, which may be an EAP-Success response message.

[0218] Step 9: TNAP sends a notification message to T-Node, notifying the T-Node of the security establishment using the TNAP key.

[0219] Step 10: TNAP sends the local IP configuration to the T-Node.

[0220] The embodiments of the present invention, based on a trusted non-3GPP access gateway, provide IoT industry terminals with 5GC deployed by operators through 5G-RG access terminal requests, realize the coordinated transmission of N3GPP short-range communication network and cellular network, and optimize the efficiency of network session link establishment and the robustness of links.

[0221] Among them, admission control is introduced in the short-range communication domain to improve the negotiation efficiency of heterogeneous non-3GPP networks by enhancing the access negotiation capabilities of trusted nodes, simplifying or merging pure signaling interactions before data stream transmission, and improving link establishment efficiency.

[0222] A relay node retrieval mechanism is introduced in the PDU session established between 5G RG and TNGF, which enables more efficient route retrieval for 5G converged services in the network session for multi-domain collaboration scenarios that may exist in industry networks, thereby reducing the load on the 5G network.

[0223] In the MSG message sent by the core network to the TNGF, a global QOS policy indication is newly added to provide a reference for resource allocation for the non-3GPP network nodes to enhance the robustness of the communication chain between the terminal and the TNGF.

[0224] like Figure 5 As shown, an embodiment of the present invention further provides a method for cooperative communication between a short-range communication network and a cellular network, which is applied to a terminal and includes:

[0225] Step 51: Send an admission control request message to a convergence node via a short-range communication network, so that the convergence node determines the access gateway function of the cellular network based on the admission control request message, wherein the admission control request message is used to indicate a data flow transmission strategy and / or negotiate a data flow diversion strategy.

[0226] The terminal can send the data stream to the aggregation node via a short-range communication network, which introduces channel coding and decoding technologies Polar and RS to optimize random interference and burst interference, thereby achieving highly reliable transmission in complex electromagnetic environments.

[0227] This embodiment introduces admission control in the short-range communication domain. By indicating the data flow transmission strategy and / or negotiating the data flow diversion strategy through admission control requests, it can enhance the access negotiation capability of trusted nodes (such as TNAP nodes), improve the negotiation efficiency of heterogeneous non-3GPP networks, simplify or merge pure signaling interactions before data flow transmission, and improve link establishment efficiency.

[0228] Step 52: Data is transmitted with the core network deployed by the operator requested by the terminal through the session connection between the convergence node and the access gateway node.

[0229] After receiving the admission control request message, the aggregation node performs a PLMN search, determines the access gateway function of the cellular network, and establishes a session connection with the access gateway function. The terminal can communicate with the core network deployed by the operator requested by the terminal through the session connection. This embodiment provides the Internet of Things industry terminal with access to the 5GC deployed by the operator requested by the terminal through the aggregation node (such as 5G-RG), realizes the collaborative transmission of non-3GPP short-range communication network and cellular network, and optimizes the efficiency of network session link establishment and the robustness of the link.

[0230] The embodiments of the present invention introduce admission control in the non-3GPP short-range communication domain while maintaining forward compatibility with existing cellular network protocols. By enhancing the access negotiation capabilities of trusted nodes, the efficiency of heterogeneous network negotiation is improved, and the pure signaling interaction process before data stream transmission is simplified or merged, thereby avoiding unnecessary link establishment overhead.

[0231] Optionally, the admission control request message includes: information related to a Quality of Service (QoS) management event; the information related to the QoS management event is used to indicate the QoS requirement of the terminal. The admission control request message may be: a Layer 2 connection request message; the Layer 2 connection request message includes a target identification field, and the target identification field includes information related to the QoS management event.

[0232] The relevant information of the QoS management event may include: AID, XQI, Port, TCID and other parameters, which are used to support rate adjustment applications to negotiate network resource scheduling. For example, when the channel is congested or the rate cannot be guaranteed, the data rate can be reduced.

[0233] In this embodiment, the target identification field is a newly added identification field in the layer 2 connection request message, which is used to indicate QoS management events, identify business characteristics and user requirements of different applications and scenarios, and map business characteristics and user requirements into QoS requirements to provide transmission status of QoS flow data.

[0234] Optionally, the method further includes: receiving an Extensible Authentication Protocol request message sent by the aggregation node, the Extensible Authentication Protocol request message being used to request identity information of the terminal; and feeding back an Extensible Authentication Protocol response message to the aggregation node, the Extensible Authentication Protocol response message including the identity information of the terminal.

[0235] In this embodiment, after the terminal establishes a connection with the aggregation node, the aggregation node, acting as an access point, may request the terminal's identity information from the terminal through an EAP process. The terminal then returns a response message to the aggregation node, including the terminal's identity information, which can be used for identity authentication. The aggregation node's response message may also carry identification information of the operator requested by the terminal, and the aggregation node may determine the cellular network to which the terminal is connected based on the operator's identification information.

[0236] Optionally, the method further includes: receiving an SMC request message sent by the access gateway node, the SMC request message including QoS policy information configured by the core network; and sending an SMC completion message to the access gateway node according to the SMC request message, the SMC completion message including QoS parameters.

[0237] After the aggregation node establishes a session connection with the access gateway function, the terminal communicates with the core network deployed by the operator requested by the terminal through the session connection. The access gateway function performs AMF selection, and after determining the AMF in the core network deployed by the operator requested by the terminal, sends an N2 message to the AMF through the N2 interface. The N2 interface is the communication interface between the access gateway function and the AMF. The AMF feeds back an N2 message, namely the SMC request message, to the access gateway function through the N2 interface. The fed-back N2 message can carry the QoS policy information configured by the core network, and the QoS policy information can provide a reference for resource allocation for the non-3GPP network nodes to which it belongs. The access gateway function can send the QoS policy information configured by the core network to the terminal through the SMC request message, and the terminal feeds back the corresponding QoS parameters to enhance the robustness of the communication chain between the terminal and the access gateway function.

[0238] Embodiments of the present invention introduce admission control in the short-range communication domain. This enhances the access negotiation capabilities of trusted nodes, improves the efficiency of heterogeneous non-3GPP network negotiation, simplifies or consolidates pure signaling interactions before data stream transmission, and improves link establishment efficiency. A new global QoS policy indication is added to the MSG message sent from the core network to the TNGF, providing a reference for resource allocation for the non-3GPP network nodes to which they belong, thereby enhancing the robustness of the communication link between the terminal and the TNGF.

[0243] In this embodiment, after the aggregation node establishes a session connection with the access gateway function, the terminal communicates with the core network deployed by the operator requested by the terminal through the session connection. The access gateway function performs AMF selection, and after determining the AMF in the core network deployed by the operator requested by the terminal, sends an N2 message to the AMF through the N2 interface. The N2 interface is the communication interface between the access gateway function and the AMF. The AMF feeds back an N2 message, i.e., the SMC request message, to the access gateway function through the N2 interface. The fed-back N2 message can carry QoS policy information configured by the core network. The QoS policy information can provide a reference for resource allocation for the non-3GPP network nodes (i.e., the aggregation node and the access gateway function) to which it belongs, so as to enhance the robustness of the communication chain between the terminal and the access gateway function.

[0244] Optionally, the method further includes: receiving an SMC completion message sent by the terminal, the SMC completion message including QoS parameters; and sending the SMC completion message to the core network.

[0245] The access gateway function can send the QoS policy information configured by the core network to the terminal through the SMC request message, and the terminal can feedback the corresponding QoS parameters through the SMC completion message to enhance the robustness of the communication chain between the terminal and the access gateway function.

[0246] In this embodiment, the msg message sent by AMF to TNGF through the N2 interface newly carries the QOS policy sent by the core network as a global QOS policy, providing a reference for resource allocation for the G nodes and T nodes in the non-3GPP network to which they belong, so as to make global optimal real-time adjustments according to the environment.

[0247] Optionally, the method further includes: sending feedback information of the QoS management event to the convergence node, where the feedback information includes QoS policy information configured by the core network.

[0248] In this embodiment, after receiving the QoS policy information sent by the AMF, the access gateway function sends feedback information about the QoS management event to the aggregation node through the AAA interface. The feedback information includes the QoS policy information. The aggregation node then provides the QoS policy information to the access layer for resource scheduling and / or management of media stream transmission channels.

[0249] In an embodiment of the present invention, a global QOS policy indication is newly carried in the MSG message sent by the core network to provide a reference for resource allocation for the non-3GPP network nodes to which it belongs, so as to enhance the robustness of the communication chain between the terminal and the access gateway function.
