The first operation includes at least one of the following: 1) sending a fourth message, the fourth message being used to instruct the receiving terminal to establish a connection with the first A request for a Packet Data Network (PDN) connection corresponding to the parameter information; 2) Send a fifth message, the fifth message being used to indicate rejection of the terminal's request to establish a PDN connection corresponding to the first parameter information; 3) Establish a PDN connection using fourth parameter information, which is the default parameter information related to routing data used by the terminal in the first network; 4) Send fourth indication information, where the fourth indication information is Update the second parameter information at the instruction terminal.

Wherein, the first parameter information is parameter information related to routing data used by the terminal in the first network. For example, the first parameter information is an EPS routing policy parameter, and the EPS routing policy parameter is a parameter used by the terminal in the EPS. , obtained through the corresponding relationship between EPS and 5GS policy parameter URSP. The second parameter information is parameter information related to routing data used by the terminal in the second network. For example, the second parameter information is URSP used by the terminal in 5GS, etc.

In various embodiments of this application, when the first network appears as the execution subject, the first network may refer to the network side device in the first network.

For example, the first parameter information is an EPS routing policy parameter, and the first indication information is used to instruct the terminal to obtain the first parameter information based on the corresponding relationship between EPS and 5GS URSP. In the related art, when the terminal sends the first parameter information to the EPS to request to establish a PDN connection, the EPS cannot know how the first parameter information of the terminal is obtained. This embodiment uses the first indication information to instruct the terminal based on the second parameter. The information obtains the first parameter information. In this way, the EPS can predict that the URSP of the terminal may not be the latest, which may cause the first parameter information to be incorrect and the terminal needs to update the URSP.

For example, the second indication information is used to indicate that the terminal has or does not have a URSP. In this way, the EPS can instruct the terminal to update or obtain the URSP through the first operation.

2) The first network receives a second message sent by the second network, and the second message includes a third Instruction information, the third indication information is used to instruct the terminal to update the second parameter information.

The subscription information of the terminal includes the subscription information of the terminal on the first network and/or the subscription information of the terminal on the second network. For example, in this embodiment, the first network learns that the terminal not only signs a contract with the first network, but also signs a contract with the second network. The second network may update the second parameter information. Therefore, the first network may instruct the terminal to update or obtain the information through the first operation. Second parameter information.

5) The first network acquires the capability information of the terminal. The capability information of the terminal is used to indicate that the terminal supports the second network. Optionally, the first message sent by the terminal may be an attachment request message. The first message carries capability information of the terminal. For example, in this embodiment, the first network learns that the terminal supports the second network mode, and the second network may update the second parameter information. Therefore, the first network may instruct the terminal to update or obtain the second parameter information through the first operation.

6) The first network obtains the registration status of the terminal, and the registration status is used to indicate the registration status of the terminal in the second network. For example, in this embodiment, the first network learns that the terminal is registered in the second network, and the second network may update the second parameter information.

For example, the first operation includes sending a fourth message, the fourth message is used to instruct the receiving terminal to establish a PDN connection corresponding to the first parameter information. In the case of a request, that is, even if the first parameter information may be wrong (because the terminal generates the first parameter information based on the second parameter information, and the second parameter information may not be the latest), the first network allows the terminal to establish If the PDN connection corresponds to the first parameter information, the terminal will first use the PDN connection corresponding to the first parameter information to obtain the third parameter information when covered by the second network. The third parameter information is the updated second parameter information. The parameter information is useful for updating the second parameter information of the terminal based on the first operation. In addition, the fourth message may also include fifth indication information, and the fifth indication information is used to indicate any of the following: 1) the terminal updates the second parameter information; 2) the second parameter information needs to be updated ;3) The terminal accesses the second network in order to update the second parameter information, and the fifth indication information included in the fourth message further facilitates updating the second parameter information of the terminal.

For another example, in the case where the first operation includes sending a fifth message, the fifth message is used to indicate rejecting the terminal's request to establish a PDN connection corresponding to the first parameter information, in this way, the terminal can learn that the first parameter information may be Wrong, that is, the second parameter information may not be the latest. The terminal can obtain the third parameter information when there is second network coverage. The third parameter information is the updated second parameter information, which is beneficial to the first operation based on Update the second parameter information of the terminal. In addition, the fifth message may also include fifth indication information, and the fifth indication information is used to indicate any of the following: 1) the terminal updates the second parameter information; 2) the second parameter information needs to be updated ;3) The terminal accesses the second network in order to update the second parameter information, and the fifth instruction information included in the fifth message further facilitates updating of the second parameter information of the terminal.

For another example, in the case where the first operation includes using the fourth parameter information to establish a PDN connection, the terminal may learn that the first parameter information may be wrong, that is, the second parameter information may not be the latest, and the terminal may not be covered by the second network. In this case, the third parameter information can be obtained. The third parameter information is the updated second parameter information, which is beneficial to updating the second parameter information of the terminal based on the first operation.

For another example, when the first operation includes sending fourth instruction information, the fourth instruction information is used to instruct the terminal to update the second parameter information, so that the terminal can obtain the third parameter information when there is second network coverage. The three-parameter information, that is, the updated second parameter information, is beneficial to updating the second parameter information of the terminal based on the first operation.
