Calling methods and devices

1. A calling method for use in a terminal configured to communicate with a device, comprising:

establishing a data channel with the device for assisting a call, when the terminal is conducting the call with the device through a voice channel; and

exchanging interaction information with the device through the data channel, wherein the interaction information is configured to assist a first user of the terminal and a second user of the device in coordinating and interacting when conducting the call, and wherein the exchanging of the interaction information with the device includes:

receiving first interaction information provided by the device through the data channel;

presenting the first interaction information in a predetermined form, wherein when the first interaction information includes a service-information page, the presenting of the first interaction information in the predetermined form includes:

parsing the service-information page; and

presenting the service-information page in a user interface; and

transmitting second interaction information to the device through the data channel.

2. The method according to claim 1 , wherein the establishing of the data channel with the device comprises:

determining whether a telephone number of the device is a preset number; and

when the telephone number is a preset number, establishing the data channel with the device for assisting the call.

3. The method according to claim 2 , wherein the determining of whether the telephone number of the device is a preset number comprises:

when the preset number is a service number, determining whether the telephone number of the device is included in a preset service-number whitelist, the service-number whitelist being stored locally in the terminal or remotely in a third-party server.

4. The method according to claim 1 , wherein the establishing of the data channel with the device comprises:

when the terminal receives a trigger signal for establishing the data channel, establishing the data channel with the device for assisting the call.

5. The method according to claim 1 , wherein

when the device is an independent calling device, the data channel is established between the terminal and the independent calling device; and

when the device includes a telephone and a server associated with the telephone, the data channel is established between the terminal and the server.

6. The method according to claim 1 , wherein the terminal establishes the data channel with the device through a third-party server.

7. The method according to claim 1 , wherein the predetermined form for presenting the first interaction information is one of displaying an image or video, playing a sound, and turning on a signal light.

8. The method according to claim 1 , wherein

the service-information page includes at least one of an information-displaying page, an information-collecting page, a service-providing page, or a service-operating page regarding a service.

9. The method according to claim 1 , wherein the presenting of the service-information page in the user interface comprises:

presenting the service-information page according to a user's operation or according to an instruction by the device.

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

when the first interaction information includes the service-information page, receiving an operation by a user on the service-information page; and

transforming the operation into the second interaction information;

wherein the service-information page includes at least one of an information-displaying page, an information-collecting page, a service-providing page, or a service-operating page regarding a service.

11. A calling method for use in a server associated with a telephone, comprising:

establishing a data channel with a terminal for assisting a call, when the telephone is conducting the call with the terminal through a voice channel; and

exchanging interaction information with the terminal through the data channel, wherein the interaction information is configured to assist a first user of the terminal and a second user of the telephone in coordinating and interacting when conducting the call, and wherein the exchanging of the interaction information with the terminal includes:

transmitting first interaction information to the terminal through the data channel;

when the first interaction information includes a service-information page, controlling presentation of the service-information page in the terminal;

receiving second interaction information provided by the terminal through the data channel; and

presenting the second interaction information in a predetermined form or using the second interaction information.

12. The method according to claim 11 , wherein

the server establishes the data channel with the terminal for assisting the call through a third-party server.

13. The method according to claim 11 , wherein the predetermined form for presenting the second interaction information is one of displaying an image and video, playing a sound, and turning on a signal light.

14. The method according to claim 11 , wherein

when the server is associated with a service number, the service-information page is associated with the service number and includes at least one of an information-displaying page, an information-collecting page, a service-providing page, or a service-operating page regarding a service.

15. The method according to claim 14 , further comprising

receiving a user operation on the service-information page; and

transforming the user operation into the second interaction information.

16. A terminal, comprising:

a processor; and

a memory for storing instructions executable by the processor;

wherein the processor is configured to:

establish a data channel with a device for assisting a call, when the terminal is conducting the call with the device through a voice channel; and

exchange interaction information with the device through the data channel, wherein the interaction information is configured to assist a first user of the terminal and a second user of the device in coordinating and interacting when conducting the call, and wherein the exchanging of the interaction information with the device includes:

receiving first interaction information provided by the device through the data channel;

presenting the first interaction information in a predetermined form, wherein when the first interaction information includes a service-information page, the presenting of the first interaction information in the predetermined form includes:

parsing the service-information page; and

presenting the service-information page in a user interface;

and

transmitting second interaction information to the device through the data channel.

17. A server associated with a telephone, the server comprising:

a processor; and

a memory for storing instructions executable by the processor;

wherein the processor is configured to:

establish a data channel with a terminal for assisting a call, when the telephone is conducting the call with the terminal through a voice channel; and

exchange interaction information with the terminal through the data channel, wherein the interaction information is configured to assist a first user of the terminal and a second user of the telephone in coordinating and interacting when conducting the call, and wherein the exchanging of the interaction information with the terminal includes:

transmitting first interaction information to the terminal through the data channel;

when the first interaction information includes a service-information page, controlling presentation of the service-information page in the terminal;

receiving second interaction information provided by the terminal through the data channel; and

presenting the second interaction information in a predetermined form or using the second interaction information.
