It should be noted that the present disclosure does not impose any specific restrictions on the type or data of UE 101.

[0052] RAN 102: This refers to the equipment used to provide wireless connectivity between UE 101 and the core network. RAN 102 is responsible for transmitting data sent and received by UE 101 to the core network and enabling mobile communications via wireless signals. Specifically, it can be understood as a base station node. It should be noted that this disclosure does not impose any specific restrictions on the type or data of RAN 102.

[0053] UPF 103: Responsible for processing user-generated data traffic. It receives user data traffic from RAN 102 and processes and forwards it according to specified policies and routing rules. As the only data processing module in the core network, it belongs to the user plane element of the core network. Specifically, it is responsible for grouping, forwarding, routing, and QoS (Quality of Service) management of user data.

[0054] SMF 104: Responsible for managing and controlling user sessions, such as establishing, modifying, and terminating user sessions.

[0059] Figure 2 is a flow chart illustrating a data transmission and identification method applied to a first network function according to an embodiment of the present disclosure. As shown in Figure 2 , the data transmission and identification method for the first network function includes at least the following steps S201 .

[0060] In step S201, a first network function identifies first information in User Datagram Protocol (UDP) information or UDP option information in a received data packet, appends the first information as second information, and sends the second information to a radio access network (RAN) device. As described above, the first network function may include UPF 103. In this step, UPF 103 decrypts and identifies a Quick UDP Internet Connection (QUIC) datagram in a data packet received from AS 108, identifies the first information in the UDP information or UDP option information in the data packet, appends the first information as second GPRS Tunneling Protocol-User Plane (GTP-U) tunnel information, and sends the second information to RAN 102. This is described in detail in S610 and S611 of Figure 6 .

[0061] Figure 3 is a flow chart illustrating a method for transmitting and identifying data applied to a second network function according to an embodiment of the present disclosure. As shown in Figure 3 , the method for transmitting and identifying data applied to a second network function includes at least the following steps S301 .

[0062] In step S301, the second network function sends first indication information to the first network function. The first indication information instructs the first network function to identify first information in the UDP information or UDP option information in a received data packet, append the first information as second information, and transmit it to the RAN device. As described above, the second network function may include SMF 104. In this step, SMF 104 sends the first indication information to UPF 103. The first indication information instructs UPF 103 to identify first information in the User Datagram Protocol (UDP) information or UDP option information in a received data packet, append the first information as second information, and transmit it to RAN 102. In other words, SMF 104 sends the first indication information to UPF 103, instructing UPF 103 to execute step S201. This is described in detail in S605 of Figure 6 .

[0063] Figure 4 is a flow chart illustrating a data transmission and identification method applied to a third network function according to an embodiment of the present disclosure. As shown in Figure 4 , the data transmission and identification method for the third network function includes at least the following steps S401 .

[0064] In step S401, a third network function receives second indication information sent by a fifth network function via a fourth network function, where the second indication information is used to instruct one or more network functions to process encrypted or QUIC messages. As described above, the third network function may include PCF 105, the fourth network function may include NEF 106, and the fifth network function may include AF 107. In this step, PCF 105 receives the second indication information sent by AF 107 via NEF 106, where the second indication information is used to instruct one or more network functions to process encrypted or QUIC messages. The one or more network functions may include SMF 104, UPF 103, etc. In other words, the second indication information may be used to notify network functions such as UPF 103 and SMF 104 to prepare for processing encrypted or QUIC messages. This is described in detail in S601 of Figure 6 .

[0065] Figure 5 is a flow chart illustrating a data transmission and identification method applied to a RAN device according to an embodiment of the present disclosure. As shown in Figure 5 , the data transmission and identification method of the RAN device includes at least the following steps S501 .

[0066] In step S501, second information sent by a first network function is received, and QoS processing or radio resource scheduling is performed based on the second information. As described above, the first network function may include UPF 103. In this step, RAN 102 performs QoS processing or radio resource scheduling based on the second information sent by UPF 103. This will be described in detail in S611 and S612 of Figure 6 .

[0067] Figure 6 is a flowchart further illustrating a data transmission and identification method according to an embodiment of the present disclosure. As shown in Figure 6 , the execution entities of the data transmission and identification method may include at least: RAN 102, a first network function (e.g., UPF 103), a second network function (e.g., SMF 104), a third network function (e.g., PCF 105), a fourth network function (e.g., NEF 106), a fifth network function (e.g., AF 107), and AS 108. The data transmission and identification method may include at least the following steps S601-S611.

[0068] S601: AF107 sends a second indication message to PCF105 via NEF106, where the second indication message is used to instruct one or more network functions to process the encrypted message or QUIC message. As mentioned above, AF107 is responsible for receiving data packets sent by AS108. Data packets are the basic units in network communication and are used to transmit data on the network. Data packets may include UDP information and UDP option information. UDP is a connectionless transport layer protocol that provides simple data transmission services. UDP information refers to the data part carried in the UDP protocol, also known as UDP datagram. In addition to UDP information, data packets may also contain UDP option information. UDP options are additional fields or information used to provide additional functions or specific configurations.

[0069] The UDP information or UDP option information is encapsulated into the QUIC datagram by AS108 and can be encrypted in the QUIC datagram.

[0070] Therefore, this step aims to allow AF107 to send a second indication message to PCF105. The second indication message can be used to notify network functions such as UPF103 and SMF104 to prepare for processing encrypted messages or QUIC messages.

[0071] S602: PCF 105 generates network policy information. As described above, PCF 105 received the second instruction information in S601. In this step, PCF 105 generates network policy information based on the second instruction information. The network policy information instructs SMF 104 to select a UPF 103 that meets certain conditions. These conditions may be preset capability rules, which can be understood as the capabilities that the UPF 103 must possess. Specifically, SMF 104 selects a UPF 103 that meets the preset capability rules from among multiple UPFs 103.

[0072] Specifically, the preset capability rules include at least one of the following: the ability to support HTTP / 3 proxy, the ability to support QUIC proxy, the ability to support encryption or decryption of QUIC messages, the ability to support encryption or decryption of data messages, and the ability to support UDP proxy.

[0073] S603: PCF 105 sends the network policy information to SMF 104. As described above, after PCF 105 generates the network policy information in S602, it sends it in this step.

[0074] S604: SMF 104 selects UPF 103. As described above, SMF 104 selects UPF 103 according to the received network policy information, and selects UPF 103 that meets the preset capability rules. The preset capability rules are as described in S602 and will not be repeated here.

[0075] S605: SMF 104 sends first instruction information to UPF 103. The first instruction information is used to instruct UPF 103 to identify and transmit data. The specific process of data identification and transmission will be detailed in S610.

[0076] In addition, SMF104 can also send data packet filtering information or data packet detection rule information to UPF103. The role of the data packet filtering information or data packet detection rule information will also be expanded in detail in S610.

[0077] S606: UPF 103 sends its uniform resource identifier URI or uniform resource locator information URL to AF 107. It should be noted that the URI or URL sent here is the URI or URL of the UPF 103 that meets the above-mentioned preset capability rules, where the URI or URL can be understood as the address of the UPF 103 that meets the above-mentioned preset capability rules.

[0078] Furthermore, UPF103 may send the URI or URL to AF107 via SMF104 and / or PCF105 and NEF106 (ie, SMF104 and NEF106, PCF105 and NEF106, or SMF104, PCF105 and NEF106), or UPF103 may send the URI or URL directly to AF107 via NEF106.

[0079] S607: AF 107 sends a URI or URL to AS 108. It should be noted that the URI or URL sent here is the URI or URL sent by UPF 103 and received by AF 107 in S606.

[0080] S608: AS108 adds the first information to the above-mentioned UDP information or UDP option information, and then encapsulates the UDP information or UDP option information into the QUIC data message, and can encrypt it in the QUIC data message.

[0081] The first information may include at least one of the following: metadata information; protocol data unit group PDU Set information; metadata information containing PDU Set information; PDU Set sequence number information; indication information of the last PDU in the PDU Set; PDU sequence number information in a PDU Set; PDU Set size information; and PDU Set importance information.

[0082] S609: AS108 sends the encapsulated and encrypted data packet to UPF103.

[0083] S610: UPF 103 decrypts the QUIC datagram in the data packet and identifies it. The identification may include:

[0084] 1) Identifying the first information in the UDP information or UDP option information in the data packet and adding the first information as the second GTP-U tunnel information. The GTP-U tunnel is a tunneling technology in the mobile communications field, implemented using the GPRS Tunnelling Protocol-User Plane (GTP-U) protocol, and is used to transmit user data between a radio access network and a core network.

[0085] 2) Identify the above-mentioned first information in the UDP information or UDP option information in the data packet, and generate third information based on the first information, where the third information can be understood as the result obtained by processing based on the first information, and the two are essentially the same, and then add the third information as the second information of the GTP-U tunnel.

[0086] 3) Identify the first information in the UDP information or UDP option information in the data packet, and map the data packet to a quality of service (QoS) flow based on the first information (Metadata for XRM).

[0087] 4) Mapping the data packet to the QoS flow may be performed based not only on the first information but also on the data packet filtering information or data packet detection rule information received in S605.

[0088] S611: UPF 103 sends second information to RAN 102, where the second information is obtained in S610.

[0089] S612: RAN 102 performs QoS processing or radio resource scheduling based on the second information.
