[0075] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home device (home appliances with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, game consoles, etc. It should be noted that the specific type of terminal 11 is not limited in this application embodiment.

As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that this application embodiment only uses a base station in an NR system as an example, but does not limit the specific type of base station.

[0076] The data processing method, apparatus, terminal, access network equipment, and core network equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0077] like Figure 2 As shown in the figure, this application provides a data processing method, including:

[0078] Step 201: The second terminal obtains the mapping rules;

[0079] It should be noted that the mapping rule is used to instruct the second terminal to perform a data address translation process;

[0080] Step 202: The second terminal performs a data address conversion process according to the mapping rules.

[0081] In this application embodiment, the second terminal refers to a terminal that receives data that was originally intended to be sent to the first terminal. For example, the second terminal is various devices in a personal Internet of Things, such as smart home devices like televisions and cameras, wearable devices, etc.

[0082] For example, a mobile phone wants to cast a video to a TV, but the app containing the video does not have a screen casting function. The mobile phone wants to achieve this function through the 5G network, that is, the data that should have arrived at the mobile phone is forwarded to the TV through the 5G network. In this case, the mobile phone corresponds to the first terminal mentioned in the embodiments of this application, and the TV corresponds to the second terminal mentioned in the embodiments of this application.

[0083] It should be noted that the first terminal can actively control the second terminal. For example, the first terminal can also be a personal control terminal under the personal Internet of Things, such as a mobile phone.

[0084] It should be noted that one way to implement the data address translation process on the second terminal is as follows: the second terminal performs the data address translation process through Network Address Translation (NAT).

[0085] It should be further explained that when the second terminal receives a data packet from the network, the data packet was originally intended to be sent to the first terminal. Therefore, the destination address of the data packet is the first terminal. If the second terminal does not perform NAT, the second terminal cannot parse the data packet. After applying the embodiments of this application, after the second terminal receives the data packet from the network, the underlying layer replaces the destination address in the data packet from the first terminal to the second terminal. This makes the higher layer of the second terminal believe that the data packet was sent to the second terminal by the network, and the second terminal can continue to parse the data packet and obtain the corresponding data.

[0086] When the second terminal sends data to the network, the source address is replaced by the first terminal, and then the data packet is sent. When the network receives the data packet, it will assume that the data packet was sent by the first terminal.

[0087] It should be noted that the mapping rule can be notified by the first terminal to the second terminal, or it can be determined by the second terminal itself. The embodiments of this application will be described in detail below from the perspective of the subject that generates the mapping rule.

[0088] I. First Terminal Mapping Rules

[0089] It should be noted that, in this case, step 201 can be optionally implemented as follows:

[0090] The second terminal receives the mapping rules sent by the first terminal.

[0091] Optionally, the mapping rule includes:

[0092] The mapping relationship between the first information of the first terminal and the second information of the second terminal;

[0093] The first information includes at least one of the following: IP address, port number, fully qualified domain name (FQDN), and Uniform Resource Locator (URL);

[0094] The second information includes at least one of the following: IP address, port number, FQDN, and URL.

[0095] It should be noted that, for example, the mapping rule can be a mapping list. Usually, the first piece of information in the mapping list corresponds one-to-one with the second piece of information. For example, the mapping list includes, but is not limited to, at least one of the following items: the IP address of the first terminal corresponds to the IP address of the second terminal, the port number of the first terminal corresponds to the port number of the second terminal, the FQDN of the first terminal corresponds to the FQDN of the second terminal, the URL of the first terminal corresponds to the URL of the second terminal, the IP address of the first terminal corresponds to the port number of the second terminal, etc.

[0096] II. One scenario where the second terminal generates mapping rules (the first terminal triggers data forwarding)

[0097] It should be noted that, in this case, step 201 can be implemented in the following ways:

[0098] The second terminal receives a first message, which requests the second terminal to perform a data address translation process;

[0099] The second terminal obtains the mapping rules based on the first message.

[0100] In other words, in this case, the mapping rule is determined by the second terminal based on the first message.

[0101] It should be noted that, typically, the first message includes at least one of the following: the IP address, port number, FQDN, and URL of the first terminal; that is, when the second terminal receives the first message, since the first message contains relevant information about the first terminal, the second terminal can generate mapping rules based on at least one of the IP address, port number, FQDN, and URL of the first terminal.

[0102] Optionally, the second terminal may acquire the first message in one of the following ways:

[0103] Implementation Method 1: The second terminal receives the first message sent by the first terminal through direct communication technology;

[0104] It should be noted that the direct communication technologies mentioned in the embodiments of this application include, but are not limited to, WLAN direct communication, Bluetooth connection communication, PC5 sidelink communication, and other technologies.

[0105] It should be further noted that after receiving the first message sent by the first terminal, the second terminal also needs to send a first acceptance message to the first terminal.

[0106] Optionally, the first acceptance message includes at least one of the following:

[0107] The IP address, port number, FQDN, and URL of the first terminal.

[0108] Implementation Method 2: The second terminal receives the first message sent by the first terminal through the access network equipment;

[0109] It should be noted that in this implementation, the second terminal and the first terminal do not communicate directly. Instead, they forward each other's interaction messages through the access network device. After the second terminal receives the first message from the first terminal, it needs to send back a first acceptance message. When the access network device receives the first acceptance message sent by the second terminal, it forwards the first acceptance message to the first terminal.

[0110] Optionally, the first acceptance message includes at least one of the following:

[0111] The IP address, port number, FQDN, and URL of the first terminal.

[0112] Implementation Method 3: The second terminal receives the first message sent by the core network device;

[0113] It should be noted that one implementation method in this case is as follows: the first terminal sends a first message to the core network device, the core network device sends the first message to the second terminal through the access network device, and the second terminal also needs to send back a first received message to the core network device.

[0114] Another implementation in this case is as follows: the first terminal sends a forwarding request to the core network device, the core network device sends a forwarding acceptance message to the access network device, the forwarding acceptance message carries at least one of the first terminal's IP address, port number, FQDN and URL; after receiving the forwarding acceptance message, the access network device sends a first message (in this case, the first message is a transfer indication) to the second terminal based on the forwarding acceptance message, and after receiving the first message, the second terminal sends a first acceptance message back to the access network device.

[0115] Specifically, the first received message includes at least one of the following: the IP address, port number, FQDN, and URL of the first terminal.

[0116] III. One scenario for generating mapping rules on the second terminal (second terminal triggers data forwarding)

[0117] It should be noted that in this case, before step 201, the following steps are also included:

[0118] The second terminal sends a second message, which requests the second terminal to perform a data address translation process.

[0119] Optionally, the second message includes at least one of the following: the IP address, port number, FQDN, and URL of the first terminal.

[0120] Optionally, the second terminal may send the second message in one of the following ways:

[0121] Implementation Method 1: The second terminal sends a second message to the first terminal via direct communication technology;

[0122] It should be noted that the direct communication technologies mentioned in the embodiments of this application include, but are not limited to, WLAN direct communication, Bluetooth connection communication, PC5 sidelink communication, and other technologies.

[0123] It should be further noted that after receiving the first message sent by the second terminal, the first terminal also needs to send a second acceptance message to the second terminal; optionally, the second acceptance message includes at least one of the following:

[0124] The IP address, port number, FQDN, and URL of the first terminal.

[0125] Furthermore, the second terminal obtains the mapping rule based on the second received message. In other words, in this case, the second terminal determines the mapping rule based on the second received message fed back by the first terminal.

[0126] Implementation Method 2: The second terminal forwards the second message to the first terminal through the access network equipment;

[0127] It should be noted that in this implementation, the second terminal and the first terminal do not communicate directly. Instead, they forward each other's interaction messages through the access network device. After the first terminal receives the second message from the second terminal, it needs to send back a second acceptance message. When the access network device receives the second acceptance message sent by the first terminal, it forwards the second acceptance message to the second terminal. The second terminal obtains the mapping rule based on the second acceptance message. In other words, in this case, the second terminal determines the mapping rule based on the second acceptance message sent back by the first terminal.

[0128] Implementation Method 3: The second terminal sends a second message to the core network equipment;

[0129] It should be noted that one implementation method in this case is as follows: the second terminal sends a second message to the core network device, the core network device sends a second accept message to the second terminal through the access network device, and the second terminal determines the mapping rule based on the second accept message.

[0130] Optionally, the second acceptance message includes at least one of the following:

[0131] The IP address, port number, FQDN, and URL of the first terminal.

[0132] It should be noted that the IP address mentioned in the embodiments of this application includes, but is not limited to, at least one of IPv4 address and IPv6 address.

[0133] The following example illustrates the data forwarding process between the various devices mentioned above in a specific application.

[0134] Specific scenario 1: There is a direct communication between the first terminal and the second terminal. After the first terminal determines the mapping rules, it sends them to the second terminal.

[0135] like Figure 3 As shown, the specific application process in this case mainly includes:

[0136] Step 300: The first terminal transmits data through a Protocol Data Unit (PDU) session;

[0137] Step 301: The first terminal establishes a direct communication connection with the second terminal;

[0138] It should be noted that this direct communication can be achieved via Bluetooth, Sidelink, Wi-Fi, wired connection, etc.

[0139] Step 302: The first terminal sends a forwarding request;

[0140] Step 303: The second terminal sends a response to forward the received message;

[0141] Optionally, the forwarding acceptance message carries at least one of the IP address and port number of the second terminal.

[0142] Step 304: The second terminal establishes a resource connection with the access network;

[0143] Typically, the second terminal needs to establish air interface resources corresponding to the access network with the assistance of the first terminal.

[0144] Step 305: The first terminal determines the mapping rules;

[0145] It should be noted that the first terminal mainly determines the mapping rules based on forwarding and receiving messages.

[0146] Step 306: The first terminal sends the mapping rules to the second terminal;

[0147] Step 307: After receiving the data packet, the second terminal performs NAT according to the mapping rules;

[0148] The second terminal transmits data through a PDU session, and the application server is unaware of the data sender and receiver.

[0149] It should be noted that in this case, there is no clear order between steps 304 and 305; the second terminal can execute either step first.

[0150] Specific Scenario 2: There is a direct communication between the first terminal and the second terminal. The first terminal initiates a forwarding request, sending its IP address and port number to the second terminal in the request. The second terminal then determines the mapping rules.

[0151] like Figure 4 As shown, the specific application process in this case mainly includes:

[0152] Step 400: The first terminal transmits data through a PDU session;

[0153] Step 401: The first terminal establishes a direct communication connection with the second terminal;

[0154] It should be noted that this direct communication can be achieved via Bluetooth, Sidelink, Wi-Fi, wired connection, etc.

[0155] Step 402: The first terminal sends the first message;

[0156] It should be noted that the first message here refers to the forwarding request; the first message carries at least one of the following: the IP address, port number, FQDN, and URL of the first terminal.

[0157] Step 403: The second terminal sends back the first received message;

[0158] It should be noted that the first message received here refers to the message received after forwarding.

[0159] Optionally, the forwarding acceptance message carries at least one of the IP address, port number, FQDN, and URL of the first terminal.

[0160] Step 404: The second terminal determines the mapping rules based on the first message;

[0161] Step 405: The second terminal establishes a resource connection with the access network;

[0162] Typically, the second terminal needs to establish air interface resources corresponding to the access network with the assistance of the first terminal.

[0163] Step 406: After receiving the data packet, the second terminal performs NAT according to the mapping rules;

[0164] The second terminal transmits data through a PDU session, and the application server is unaware of the data sender and receiver.

[0165] It should be noted that in this case, there is no clear order between steps 404 and 405; the second terminal can execute either step first.

[0166] Specific Scenario 3: There is no direct communication between the first terminal and the second terminal. The first terminal forwards a forwarding request through the RAN, carrying the IP address and port number in the forwarding request. The second terminal determines the mapping rules.

[0167] like Figure 5 As shown, the specific application process in this case mainly includes:

[0168] Step 500: The first terminal transmits data through a PDU session;

[0169] Step 501: The first terminal sends a first message to the second terminal through the access network;

[0170] It should be noted that the first message here refers to the forwarding request; the first message carries at least one of the following: the IP address, port number, FQDN, and URL of the first terminal.

[0171] Step 502: The second terminal sends a first accept message to the first terminal through the access network;

[0172] It should be noted that the first message received here refers to the message received after forwarding.

[0173] Step 503: The second terminal determines the mapping rules based on the first message;

[0174] Step 504: The second terminal establishes a resource connection with the access network;

[0175] Typically, the second terminal needs to establish air interface resources corresponding to the access network with the assistance of the first terminal.

[0176] Step 505: After receiving the data packet, the second terminal performs NAT according to the mapping rules;

[0177] The second terminal transmits data through a PDU session, and the application server is unaware of the data sender and receiver.

[0178] It should be noted that in this case, there is no clear order between steps 503 and 504; the second terminal can execute either step first.

[0179] Specific Scenario 4: There is no direct communication between the first terminal and the second terminal. The first terminal initiates a data forwarding request to the SMF. After the SMF agrees, it sends a transfer acceptance message to the RAN, carrying the IP address and port number of the first terminal in the transfer acceptance message. The RAN sends a transfer instruction to the second terminal, carrying the IP address and port number of the first terminal in the transfer instruction message. After the first terminal determines the mapping rules, it sends them to the second terminal.

[0180] like Figure 6 As shown, the specific application process in this case mainly includes:

[0181] Step 600: The first terminal transmits data through a PDU session;

[0182] Step 601: The first terminal sends a forwarding request to the SMF;

[0183] Step 602: The SMF sends a forwarding and receiving message to the access network;
