The SMF network element can be used for session management, allocation and management of Internet Protocol (IP) addresses for terminals, selection and control of User Plane Functions (UPFs), flow control, policy enforcement, and Quality of Service (QoS) control, among other things.

[0093] In some embodiments, the terminal 101 and the core network device 102 can be connected through the access network device 103. Optionally, the access network device 103 may be, for example, a node or device that connects the terminal to the wireless network. The access network device 103 may include at least one of the following in a 5G communication system: evolved Node B (eNB), next generation eNB (ng-eNB), next generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), wireless backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0094] 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.

[0095] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. 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.

[0096] 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), 6th generation mobile communication system (6G), 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, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0097] Optionally, non-3GPP devices can include, for example, television equipment, camera equipment, etc., without limitation.

[0098] Optionally, non-3GPP devices can access the network and obtain network services by connecting to a terminal (e.g., UE) and / or a 5G residential gateway (5G-RG). After a non-3GPP device connects to a terminal, its service traffic can be mapped to the QoS rules of a certain QoS flow in the terminal's existing Packet Data Unit (PDU) session, or the terminal can decide to establish and / or modify a PDU session and / or QoS flow to achieve differentiated QoS for non-3GPP devices obtaining network services. The creation, deletion, and modification of QoS flows and QoS rules are typically implemented by core network equipment (e.g., SMF) in the network. The SMF can provide the terminal with one or more QoS flow descriptions related to the PDU session when the PDU session is established or modified. The function of the QoS flow description information element is to indicate a set of QoS flow descriptions used by the terminal. If the authorized QoS flow description information of the PDU session is modified, or marked as needing to be synchronized with the terminal, the SMF can set the authorized QoS flow description information element (IE) in the PDU session modification command message to the authorized QoS flow description of the PDU session. If the SMF creates a new authorized QoS rule for a new Quality of Service (QoS) flow, the SMF can include the authorized QoS flow description for that QoS flow in the Authorized QoS Flow Description Information Element (IE) of the PDU Session Modification Command Message.

[0099] Optionally, the terminal can only decide to send a PDU session modification request to the network if the QoS flow description in the PDU session establishment accept message received by the terminal contains an error (e.g., a semantic error or syntax error in the QoS operation). However, in related technologies, when a non-3GPP device terminates its service or the communication connection between the non-3GPP device and the terminal is broken, if any QoS rule of a certain QoS flow is no longer bound to any service traffic, the terminal cannot trigger the network to delete the QoS flow in a timely manner. This results in multiple unreleased idle QoS flows in the network, which wastes network resources and affects communication performance.

[0100] Optionally, when a QoS rule is unbound from all services, the terminal can delete the local QoS rule. If a QoS flow is no longer bound to any QoS rule, the terminal can trigger the network to delete the idle QoS flow via a PDU session modification request (which may include a QoS flow deletion request or non-3GPP device information). The network can delete the relevant QoS flow based on the received QoS flow deletion request or non-3GPP device information.

[0101] Optionally, the first data stream may be referred to as a QoS stream, a quality of service stream, or a data stream, without restriction.

[0296] Optionally, the following embodiments are available:

[0297] As shown in Figure 5A, which is an interactive schematic diagram of a communication method according to another embodiment of the present disclosure, the first device is a non-3GPP device, the terminal is a UE, the access method is 3GPP access and / or non-3GPP access, the core network equipment is SMF and AMF, the first data stream is a QoS stream, and the rule information is a QoS rule. In Figure 5A, if the non-3GPP device terminates the service, the QoS stream is deleted.

[0298] Step 0a: Establish a connection between the non-3GPP device and the UE.

[0299] Step 1a: Non-3GPP equipment terminates service.

[0300] Optionally, the termination of service for non-3GPP equipment may include at least one of the following:

[0301] a) Service shutdown for non-3GPP equipment.

[0302] b) The UE terminates the service of non-3GPP equipment.

[0303] Step 2a: The UE sends a PDU session modification request message (including QoS flow deletion container) to the SMF through 3GPP access and / or non-3GPP access and AMF.

[0304] Optionally, in some embodiments, the PDU session modification request message may be referred to as a PDU Session Modification Request.

[0305] Alternatively, in some embodiments, the QoS flow deletion container may be referred to as a QoS flow Deletion Container.

[0306] Optionally, in some embodiments, when a non-3GPP device terminates its service, the UE can delete the QoS rules bound to that service. If any QoS rule of a QoS flow is not bound to any service traffic, the UE sends a PDU session modification request message containing a QoS flow deletion container to the network, requesting the deletion of the specific QoS flow in the network.

[0307] Optionally, in some embodiments, the QoS flow deletion container described above may include:

[0308] 1. QoS flow deletion information. This may include, for example, the QFI and the reason for deletion.

[0309] 2. QoS Flow Description: The opcode in the QoS Flow Description indicates that the existing QoS Flow Description should be deleted.

[0310] 2. The cause value for 5GSM session management is "QoS rules for QoS flow are not bound to any service".

[0311] Among them, the 5GSM reason value refers to the code in the network used to indicate the specific reason for the SMF to reject or process the request.

[0312] Step 2b: The SMF sends a PDU session modification command message to the UE through the AMF, 3GPP access and / or non-3GPP access.

[0313] Optionally, in some embodiments, the PDU session modification command message may be referred to as the PDU Session Modification Command.

[0314] Optionally, in some embodiments, the SMF receives a PDU session modification request message and may return a PDU session modification command message to the UE containing the QoS flow deletion status (an optional example of the above processing result).

[0315] As shown in Figure 5B, which is an interactive schematic diagram of a communication method according to another embodiment of the present disclosure, the first device is a non-3GPP device, the terminal is a UE, the access method is 3GPP access and / or non-3GPP access, the core network equipment is SMF and AMF, the first data stream is a QoS stream, and the rule information is a QoS rule. In Figure 5B, if the connection between the non-3GPP device and the UE is broken, the QoS stream is deleted.

[0316] Step 0b: Establish a connection between the non-3GPP device and the UE.

[0317] Step 1b: Disconnection.

[0318] Optionally, in some embodiments, a non-3GPP device may initiate the disconnection from the UE.

[0319] Optionally, in some embodiments, the UE may release the connection with non-3GPP devices.

[0320] Step 2b: The UE sends a PDU session modification request message (including non-3GPP device information) to the SMF through 3GPP access and / or non-3GPP access and AMF.

[0321] Optionally, in some embodiments, after disconnecting the connection between the non-3GPP device and the UE, the UE can delete the QoS rules bound to the non-3GPP device. If any QoS rules of the QoS flow are not bound to any service traffic, the UE sends a PDU session modification request message containing non-3GPP device information to the network. This non-3GPP device information may include:

[0322] 1. Non-3GPP device ID.

[0323] 2. Connection status: The connection status can be disconnected.

[0324] 3. QoS Flow Description: The opcode in the QoS Flow Description indicates that the existing QoS Flow Description should be deleted.

[0325] 4. The 5GSM cause value is "The QoS rules for the QoS flow are not bound to any service".

[0326] The aforementioned PDU session modification request message may also contain QoS flow deletion information, which may include one or more QFIs.

[0327] Step 3b: The SMF sends a PDU session modification command message to the UE through the AMF, 3GPP access and / or non-3GPP access.

[0328] Optionally, in some embodiments, the SMF receives a PDU session modification request message, determines the deletion of the relevant QoS flow based on the received non-3GPP device information, and returns a PDU session modification command message containing the QoS flow deletion status to the UE.

[0329] Optionally, in some embodiments, the UE can send a request to the network to delete QoS flows through a PDU session modification request message, which can release idle QoS flows in a timely manner and avoid wasting network resources.

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 using an application-specific integrated circuit (ASIC) or a programmable logic device (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), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
