5. The system according to claim 1 , wherein:

the application service device is further configured to send the first service page information to the application media device when detecting that the call service is connected; and

wherein the application media device is further configured to receive the first service page information from the application service device.

6. A method, comprising:

receiving, by an application service device, a data channel establishment request message from a terminal device, wherein the data channel establishment request requests to establish a data channel;

sending, by the application service device, a data channel establishment indication message to an application media device in response to receiving the data channel establishment request message, to indicate to the application media device to establish the data channel with the terminal device;

receiving, by the application media device, the data channel establishment indication message from the application service device;

establishing, by the application media device, the data channel with the terminal device; and

sending, by the application media device, first service page information corresponding to a call service to the terminal device through the data channel.

7. The method according to claim 6 , further comprising:

receiving, by the application media device, user operation information of the terminal device;

converting, by the application media device, the user operation information into audio information; and

sending, by the application media device, the audio information to a call center through a media channel between the terminal device and the call center.

8. The method according to claim 6 , further comprising:

receiving, by the application media device, data of the terminal device through the data channel;

sending, by the application media device, the data of the terminal device to the application service device;

receiving, by the application service device, the data of the terminal device;

obtaining, by the application service device, user operation information of the terminal device from the data of the terminal device; and

sending, by the application service device, the user operation information of the terminal device to the application media device.

9. The method according to claim 6 , further comprising:

receiving, by the application media device, user operation information from the terminal device through the data channel.

10. The method according to claim 6 , further comprising:

sending, by the application service device, the first service page information to the application media device when detecting that the call service is connected; and

receiving, by the application media device, the first service page information.

11. The method according to claim 10 , further comprising:

receiving, by the application media device, data of the terminal device through the data channel;

sending, by the application media device, the data of the terminal device to the application service device; and

receiving, by the application service device, the data of the terminal device; and

wherein sending, by the application service device, the first service page information to the application media device comprises:

obtaining, by the application service device, a call start event, a call notification message, or a call connection event in the data of the terminal device, and

sending, by the application service device, the first service page information corresponding to the call start event, the call notification message, or the call connection event to the application media device.

12. The method according to claim 6 , further comprising:

receiving, by the application service device, user operation information of the terminal device, and

sending, by the application service device, second service page information corresponding to the user operation information to the application media device.

13. The method according to claim 6 , further comprising:

sending, by the application media device, page indication information to the terminal device through the data channel, wherein the page indication information indicates to the terminal device to display a user interface (UI) page corresponding to the first service page information or buffer the UI page.

14. A method, comprising:

establishing, by an application service device, a data channel with a terminal device when detecting that the terminal device initiates or receives a call service,

sending, by the application service device, first service page information corresponding to the call service to the terminal device through the data channel,

receiving, by the application service device, user operation information from the terminal device through the data channel,

sending, by the application service device, the user operation information to an application media device;

receiving, by the application media device, the user operation information from the application service device;
