The address translation control method, device, terminal, and network element provided in the embodiments of the present application are described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

As shown in Figure 2, this embodiment of the present application provides an address translation control method, including:

Step 201, the first network element receives the first rule sent by the second network element, and the first rule is used for the data address translation process of the first network element;

Step 202, execute a data address conversion process according to the first rule.

It should be noted that the first network element mentioned in the embodiment of the present application mainly realizes the user plane function (User Plane Function, UPF), and what the second network element mainly realizes is the session management function (Session Management Function, SMF) , the data address translation rules used by UPF are usually notified by SMF.

Optionally, in an implementation manner, the first rule is directly used by the first network element to perform data address translation. In this case, the first network element may directly use the first rule sent by the second network element, Execute the data address translation process; optionally, in another implementation mode, the first rule is to assist the first network element in the data address translation process, that is, in this case, the first network element cannot directly use the The first rule executes the data address translation process. Optionally, in this case, the implementation of step 202 is as follows:

updating a second rule according to the first rule, where the second rule is used by the first network element to perform a data address translation process;

According to the second rule, a data address translation process is performed.

It should be further noted that, an implementation manner for the first network element to execute the data address translation process is: the first network element executes the data address translation process by means of Network Address Translation (NAT).

For example, when the first network element receives a data packet from the network, the data packet is originally intended to be sent to the first terminal, so the destination address of the data packet is the first terminal, if the first network element does not perform NAT, then The data packet will still be sent to the first terminal, or even if the first network element can send the data packet to the second terminal in other ways, the first network element does not perform NAT, and the second terminal cannot receive the data packet. Analysis; after applying the embodiment of the present application, after the first network element receives the data packet of the network, first replace the target address in the data packet from the first terminal to the second terminal, and then the first network element can be based on the converted The destination address of the data packet is used to send the data packet to the second terminal.

It should be noted that the first network element executes the data address translation process according to the received first rule for the first network element to perform the data address translation process, so as to ensure the data forwarding of the 5G network and the reliability of communication.

Step 301, the second network element receives the first policy information sent by the third network element;

Step 303, the second network element sends the first rule to the first network element according to the first policy information;

It should be noted that since the policy control function (Policy Control Function, PCF) is mainly to implement policy formulation and management, that is to say, the third network element mentioned in the embodiment of the present application mainly implements the PCF.

It should be noted that after the PCF sends the first policy information to the SMF, the SMF needs to obtain the first rule (that is, the data forwarding rule) according to the first policy information, and then send the obtained first rule to the UPF.

Optionally, the PCF usually sends the policy based on the request of the SMF, that is, before the step 301, it also includes:

The second network element sends a first request message to the third network element, where the first request message is used to request the first policy information.

Optionally, the first request message includes at least one of the following: the first terminal's Internet Protocol (Internet Protocol, IP) address, port number, fully qualified domain name (Fully Qualified Domain Name, FQDN) and Uniform Resource Locator ( Uniform Resource Locator, URL).

Optionally, the first request message may be an Npcf_SMPolicyControl_Update request message.

It should be noted that the second terminal mentioned in this application refers to the terminal that receives the data that originally needs to be sent to the first terminal. For example, the second terminal is various devices in the Personal Internet of Things, such as TV, camera Smart home, wearable devices, etc.

For example, a mobile phone wants to cast a video on a TV, but the application program (APP) where the video is located does not have the screen casting function. If the network is forwarded to the TV, the mobile phone corresponds to the first terminal mentioned in the embodiment of the present application, and the TV corresponds to the second terminal mentioned in the embodiment of the present application.

It should be noted that since 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.

Optionally, usually the second network element requesting a policy is triggered based on a terminal request, that is, before the second network element receives the first policy information sent by the third network element, it further includes:

The second network element receives the second request message sent by the first terminal, where the second request message is used to request the second network element to perform a data address translation process.

Optionally, the second request message includes at least one of the following:

IP address, port number, FQDN and URL of the second terminal.

That is to say, which terminal the first terminal requests to forward the data to, then the second request message carries the address information of the terminal receiving the forwarded data. Optionally, the address information includes but is not limited to IP address, port number At least one of , FQDN and URL.

Optionally, the second request message is a protocol data unit (Protocol Data Unit, PDU) session modification request (session modification request) message.

It should be noted that the main implementation process in the embodiment of this application is:

The first terminal sends a second request message to the second network element, the second network element sends a first request message to the third network element, the third network element feeds back the first policy information based on the first request message, and the second network element Generate the first rule according to the first policy information, and send the first rule to the first network element; At least one of the IP address, port number, FQDN and URL and the first policy information establish an association between the first terminal and the second terminal.

It should be noted that, in order to save network resources when the data packets of the network are sent to the second terminal, it is usually necessary to disconnect the connection between the first terminal and the network. Optionally, in one case, in the After the second network element receives the first policy information sent by the third network element, it further includes:

The second network element sends a first indication message to the first terminal, where the first indication message is used to indicate that the communication resource between the second network element and the second terminal has been established.

It should be noted that in this case, the first terminal actively releases the connection with the network according to the network instruction. Optionally, in another case, the network may also actively release the connection with the first terminal. The specific implementation method is as follows: After the second network element receives the first policy information sent by the third network element, the method further includes:

The second network element releases the communication resource established with the first terminal.

It should be noted that, through cooperation between the second network element and the first network element, it can be ensured that the network can accurately forward data.
