Authentication method and apparatus and device

1. An authentication method, comprising:

sending, by a core network device disposed between a terminal device of a user and a data network device, an authentication request message of the user to the data network device, wherein the authentication request message requests that the data network device perform identity authentication on the user, the authentication request message comprises first information indicating user identity information of the user, and the authentication request message further comprises the user identity information, wherein the user identity information is located in a container of the authentication request message, and wherein the first information is located outside the container of the authentication request message; and

receiving, by the core network device, an authentication response message from the data network device, wherein the authentication response message comprises the first information.

2. The method according to claim 1 , further comprising performing, before the sending the authentication request message:

receiving, by the core network device, a registration request message from the terminal device, wherein the registration request message comprises the first information and the user identity information, wherein the user identity information is disposed in a container of the registration request message, and wherein the first information is disposed outside the container of the registration request message.

3. The method according to claim 1 , further comprising performing, before the sending the authentication request message:

sending, by the core network device, a user identity request message to the terminal device; and

receiving, by the core network device, a user identity response message from the terminal device, wherein the user identity response message comprises the first information and the user identity information.

4. The method according to claim 1 , further comprising:

obtaining, by the core network device, an identifier of the terminal device; and

storing, by the core network device, a correspondence between the identifier of the terminal device and the first information.

5. The method according to claim 1 , wherein the sending the authentication request message comprises:

obtaining, by the core network device, the first information;

determining, by the core network device, address information of the data network device based on the first information; and

sending, by the core network device, the authentication request message to the data network device based on the address information.

6. An authentication apparatus, comprising:

at least one processor; and

a non-transitory computer readable memory coupled to the at least one processor and having a program stored thereon for execution by the at least one processor, the program including instructions to:

send an authentication request message of a user to a data network device, wherein the authentication apparatus is disposed between a terminal device of the user and the data network device, wherein the authentication request message requests that the data network device perform identity authentication on the user, the authentication request message comprises first information indicating user identity information of the user, and the authentication request message further comprises the user identity information, wherein the user identity information is located in a container of the authentication request message, and wherein the first information is located outside the container of the authentication request message; and

receive an authentication response message from the data network device, wherein the authentication response message comprises the first information.

7. The apparatus according to claim 6 , wherein the program further includes instructions to:

receive, before sending the authentication request message to the data network device, a registration request message from the terminal device, wherein the registration request message comprises the first information and the user identity information, wherein the user identity information is disposed in a container of the registration request message, and wherein the first information is disposed outside the container of the registration request message.

8. The apparatus according to claim 6 , wherein the program further includes instructions to:

send, before sending the authentication request message to the data network device, a user identity request message to the terminal device; and

receive a user identity response message from the terminal device, wherein the user identity response message comprises the first information and the user identity information.

9. The apparatus according to claim 6 , wherein the program further includes instructions to:

obtain an identifier of the terminal device; and

store a correspondence between the identifier of the terminal device and the first information.

10. The apparatus according to claim 6 , wherein the program further includes instructions to:

obtain the first information, and determine address information of the data network device based on the first information; and

send the authentication request message to the data network device based on the address information.

11. A non-transitory computer-readable storage medium having instructions stored thereon which, when executed by an apparatus, cause the apparatus to:

send an authentication request message of a user to a data network device, wherein the apparatus is disposed between a terminal device of the user and the data network device, wherein the authentication request message requests that the data network device perform identity authentication on the user, the authentication request message comprises first information indicating user identity information of the user, and the authentication request message further comprises the user identity information, wherein the user identity information is located in a container of the authentication request message, and wherein the first information is located outside the container of the authentication request message; and

receive an authentication response message from the data network device, wherein the authentication response message comprises the first information.

12. The non-transitory computer-readable storage medium according to claim 11 , wherein the instructions, when executed by the apparatus, further cause the apparatus to:

receive, before sending the authentication request message to the data network device, a registration request message sent by the terminal device, wherein the registration request message comprises the first information and the user identity information, wherein the user identity information is disposed in a container of the registration request message, and wherein the first information is disposed outside the container of the registration request message.

13. The non-transitory computer-readable storage medium according to claim 11 , wherein the instructions, when executed by the apparatus, further cause the apparatus to:

send, before sending the authentication request message to the data network device, a user identity request message to the terminal device; and

receive a user identity response message sent by the terminal device, wherein the user identity response message comprises the first information and the user identity information.

14. The non-transitory computer-readable storage medium according to claim 11 , wherein the instructions, when executed by the apparatus, further cause the apparatus to:

obtain the first information, and determine address information of the data network device based on the first information; and

send the authentication request message to the data network device based on the address information.
