[0032] Hereinafter, with reference to the drawings, the data processing method, device, terminal, access network equipment and core network equipment provided in the embodiments of the present application will be described in detail through several embodiments and their application scenarios.

[0033] As shown in FIG. 2, an embodiment of the present application provides a data processing method, which includes the following steps.

[0034] Step 201: A second terminal obtains a mapping rule.

[0035] It should be noted that the mapping rule is for instructing the second terminal to perform a data address conversion process.

[0036] Step 202: The second terminal performs a data address conversion process according to the mapping rule.

[0037] In the embodiment of the present application, the second terminal refers to a terminal that receives data that should be transmitted to the first terminal. For example, the second terminal is a variety of devices in a personal IoT such as a smart home device such as a television or a camera, or a wearable device.

[0038] For example, a mobile phone wants to cast a video to a TV, but the application (APP) in which the video is located does not have a casting function. The mobile phone realizes this function through a 5G network, that is, the mobile phone wants to transfer data that should be originally sent to the mobile phone through the 5G network to the TV. In this case, the mobile phone corresponds to the first terminal referred to in the embodiment of this application, and the TV corresponds to the second terminal referred to in the embodiment of this application.

[0039] It should be noted that the first terminal can actively control the second terminal, so that the first terminal may be, for example, a personal control terminal under personal IoT, such as a mobile phone.

[0040] It should be noted that the implementation manner of the second terminal performing the data address translation process is that the second terminal performs the data address translation process through Network Address Translation (NAT).

[0041] It should be further explained that when the second terminal receives a data packet from the network, the data packet should be sent to the first terminal, so the destination address of the data packet is the first terminal, and the second terminal must perform NAT to analyze the data packet. After the embodiment of the present application is applied, after the second terminal receives the data packet from the network, the lower layer replaces the destination address in the data packet from the first terminal to the second terminal, so that the upper layer of the second terminal believes that the data packet is sent from the network to the second terminal, and the second terminal can continue to analyze the data packet to obtain the corresponding data.

[0042] When the second terminal sends data to the network, it replaces the source address from the second terminal to the first terminal, and then realizes the transmission of the data packet, so that after receiving the data packet, the network believes that the data packet is sent from the first terminal.

[0043] It should be noted that the mapping rule may be notified from the first terminal to the second terminal, or may be determined by the second terminal itself. From the viewpoint of the generator of the mapping rule, the embodiments of the present application will be described in detail as follows.

[0044] 1. The first terminal generates a mapping rule It should be noted that in this case, any implementation of step 201 may be The second terminal receives the mapping rule transmitted from the first terminal.

[0045] Optionally, the mapping rule comprises: A mapping relationship between first information of the first terminal and second information of the second terminal; The first information includes at least one of an Internet Protocol (IP) address, a port number, a Fully Qualified Domain Name (FQDN), and a Uniform Resource Locator (URL), The second information includes at least one of an IP address, a port number, an FQDN, and a URL.

[0046] It should be noted that the mapping rule may be a mapping list, and usually, the first information and the second information in the mapping list have a one-to-one correspondence, for example, the mapping list includes at least one of the following: 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., but is not limited to these.

[0047] Second, the second device generates a mapping rule (data transfer is triggered by the first device) It should be noted that in this case, any implementation of step 201 may be The second terminal receives a first message, and the first message is for requesting the second terminal to perform a data address translation process; The second terminal obtains the mapping rule through the first message.

[0048] That is, in this case, the mapping rule is the one that the second terminal has determined based on the first message.

[0049] It should be noted that the first message usually includes at least one of the IP address, port number, FQDN and URL of the first terminal, that is, after the second terminal receives the first message, the first message includes the relevant information of the first terminal, so that the second terminal can generate a mapping rule according to at least one of the IP address, port number, FQDN and URL of the first terminal.

[0050] Optionally, the manner in which the second terminal obtains the first message can be one of the following manners:

[0051] Implementation method 1: The second terminal receives the first message sent from the first terminal through a direct communication technique.

[0052] It should be noted that the direct communication technology in the embodiments of the present application includes, but is not limited to, technologies such as WLAN direct connection communication, Bluetooth connection communication, PC5 Sidelink communication, etc.

[0053] It should be further explained that after the second terminal receives the first message sent from the first terminal, the second terminal also needs to send a first receipt message to the first terminal.

[0054] Optionally, the first receipt message comprises: The information includes at least one of the IP address, port number, FQDN, and URL of the first terminal.

[0055] Implementation method 2: The second terminal receives the first message sent from the first terminal through the access network device.

[0056] It should be noted that in this implementation, the second terminal and the first terminal do not communicate directly, but transfer their interactive messages through the access network device. After the second terminal receives the first message of the first terminal, it needs to feed back the first receipt message, and after the access network device receives the first receipt message sent by the second terminal, it transfers the first receipt message to the first terminal.

[0057] Optionally, the first receipt message comprises: The information includes at least one of the IP address, port number, FQDN, and URL of the first terminal.

[0058] Implementation method 3: The second terminal receives the first message sent from the core network device.

[0059] It should be noted that one implementation manner in this case is that the first terminal sends a first message to the core network equipment, the core network equipment sends the first message to the second terminal through the access network equipment, and the second terminal further needs to feed back the first receiving message to the core network equipment.

[0060] Another implementation method in this case is that the first terminal sends a forwarding request to a core network device, the core network device sends a forwarding receipt message carrying at least one of the first terminal's IP address, port number, FQDN, and URL to the access network device, and after the access network device receives the forwarding receipt message, it sends a first message (in this case, the first message is a forwarding instruction) to the second terminal through the forwarding receipt message, and after the second terminal receives the first message, it feeds back the first receipt message to the access network device.

[0061] Specifically, the first receiving message includes at least one of an IP address, a port number, an FQDN, and a URL of the first terminal.

[0062] 3. The second terminal generates a mapping rule (data transfer is triggered by the second terminal) It should be noted that in this case, before step 201, The method further includes a step of the second terminal sending a second message, the second message being for requesting the second terminal to perform a data address translation process.

[0063] Optionally, the second message includes at least one of an IP address, a port number, an FQDN, and a URL of the first terminal.

[0064] Optionally, the manner in which the second terminal sends the second message can adopt one of the following implementation manners:

[0065] Implementation method 1: The second terminal sends a second message to the first terminal through a direct communication technique.

[0066] It should be noted that the direct communication technology in the embodiments of the present application includes, but is not limited to, technologies such as WLAN direct connection communication, Bluetooth connection communication, PC5 sidelink communication, etc.

[0067] It should be further noted that after receiving the first message sent by the second terminal, the first terminal further needs to send a second receipt message to the second terminal. Optionally, the second receipt message includes: The information includes at least one of the IP address, port number, FQDN, and URL of the first terminal.

[0068] Furthermore, the second terminal obtains the mapping rule according to the second receiving message, that is, in this case, the second terminal determines the mapping rule according to the second receiving message fed back from the first terminal.

[0069] Implementation manner 2: The second terminal transmits a second message to the first terminal through an access network device.

[0070] It should be noted that in this implementation, the second terminal and the first terminal do not communicate directly, but transfer their interactive messages through the access network device. After the first terminal receives the second message of the second terminal, it needs to feed back the second receipt message, and when the access network device receives the second receipt message sent from the first terminal, it transfers the second receipt message to the second terminal. The second terminal obtains the mapping rule according to the second receipt message, that is, in this case, the second terminal determines the mapping rule according to the second receipt message fed back from the first terminal.

[0071] Implementation method 3: The second terminal sends a second message to the core network device.

[0072] It should be noted that the implementation manner in this case is that the second terminal sends a second message to the core network equipment, the core network equipment sends a second receiving message to the second terminal through the access network equipment, and the second terminal determines the mapping rule based on the second receiving message.

[0073] Optionally, the second receipt message comprises: The information includes at least one of the IP address, port number, FQDN, and URL of the first terminal.

[0074] It should be noted that the IP address in the embodiments of the present application includes, but is not limited to, at least one of an IPv4 address and an IPv6 address.

[0075] In the following, in a specific application, the data transfer process through specific interactions between the above-mentioned devices will be described by way of example as follows.

[0076] Specific situation 1: There is a direct connection communication between the first terminal and the second terminal, and after the first terminal determines the mapping rule, it transmits it to the second terminal.

[0079] Step 301: A first terminal establishes a direct communication connection with a second terminal.

[0080] It should be noted that the direct communication can be achieved by methods such as Bluetooth, Sidelink, WIFI, wired connection, etc.

[0081] Step 302: The first terminal sends a transfer request.

[0082] Step 303: The second terminal feeds back a transfer receipt message.

[0084] Step 304: The second terminal establishes a resource connection with the access network.

[0085] Typically, the second terminal needs to be assisted by the first terminal to establish corresponding air interface resources in the access network.

[0087] It should be noted that the first terminal determines the mapping rule mainly according to the forwarding receipt message.

[0088] Step 306: The first terminal sends the mapping rule to the second terminal.

[0089] Step 307: After the second terminal receives the data packet, it performs NAT according to the mapping rule.

[0090] The second terminal transmits data through the PDU session, and the application server is unaware of who is sending and receiving the data.

[0104] Typically, the second terminal needs to be assisted by the first terminal to establish corresponding air interface resources in the access network.

[0105] Step 406: After the second terminal receives the data packet, it performs NAT according to the mapping rule.

[0106] The second terminal transmits data through the PDU session, and the application server is unaware of who is sending and receiving the data.

[0107] It should be noted that in this case, step 404 and step 405 have no clear order relationship, and the second terminal may execute either step first.

[0108] Specific situation 3: There is no direct connection communication between the first terminal and the second terminal, the first terminal forwards a forwarding request through the RAN, the forwarding request carries an IP address and a port number, and the second terminal determines a mapping rule.

[0119] The second terminal transmits data through the PDU session, and the application server is unaware of who is sending and receiving the data.
