Abstract

Techniques are described for switching from a data session to a voice session, then back to the data session. A "primary" data connection is established between a user'"'"'s terminal and a communications network, which provides the user terminal with a tag identifying a voice network address (typically of a service provider) to which a voice connection can be established. The user initiates a voice connection (session) with the service provider by selecting a displayed service object associated with the service tag. During the voice session, the data session is suspended. Upon completion of the voice session, the "primary" data session is resumed. In an embodiment of the invention, a "secondary" data connection can be established during the voice session using one or more physical network connections. Data communication during the secondary data connection is optionally "remotely" guided by the service provider, and may include a distinct address for resuming the primary data connection. Video connections are accommodated during the voice session.

Claims

1. A method of establishing voice and data connections using a communication terminal device, comprising:

providing a communication terminal device, said communication terminal device including an input device and a display device;

establishing a primary data connection between the communication terminal device and a data communication network;

providing within the communication terminal device a service tag identifying a voice network address to which a voice connection can be established;

providing, on the display device, a displayed service object associated with the service tag;

selecting the service object with the input device;

upon selection of the service object, employing a voice communication module to establish a voice connection to the voice network address, retaining context information related to the data connection, and suspending the primary data connection;

in conjunction with establishing the voice connection establishing a secondary data connection between the communication terminal device and the data communication network; and

upon completion of the voice communication using the voice connection, terminating the voice session and resuming the primary data connection.

2. A method, according to claim 1, wherein:

the voice connection and the secondary data connection are both made to a service provider.

3. A method, according to claim 1, wherein:

the voice connection and the secondary data connection are both accomplished using one physical network connection.

4. A method, according to claim 1, wherein:

the voice connection and the secondary data connection are accomplished using more than one physical network connection.

5. A method, according to claim 2, wherein:

data communication via the secondary data connection is remotely guided by the service provider.

6. A method, according to claim 1, further comprising:

receiving network navigational information via the secondary data communication connection.

7. A method, according to claim 1, wherein:

data communication via the secondary data connection is remotely guided.

8. A method, according to claim 1, further comprising:

receiving, via the secondary data connection, a resumption network address.

9. A method, according to claim 8, further comprising:

establishing a data connection to the resumption network address upon resumption of the primary data connection.

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

providing a video module for establishing a video connection with a video communication network; and

employing the video module to establish a video connection in conjunction with the voice connection.

11. A method, according to claim 1, further comprising:

providing a video module for establishing a video connection with a video communication network; and

employing the video module to establish a video connection in conjunction with the voice connection.

12. A method, according to claim 11, wherein:

the service tag further identifies a video network address, to which the video connection is established.

13. A method, according to claim 11, wherein:

the voice connection, video connection, and secondary data connection are all accomplished using one physical network connection.

14. A method, according to claim 11, wherein:

the voice connection, video connection, and secondary data connection are accomplished using more than one physical network connection.

15. A method of establishing a voice and data connections using a communication terminal device, comprising:

providing a communication terminal device, said communication terminal device including an input device and a display device;

establishing a primary connection between the communication terminal device and a data communication network;

providing within the communication terminal device a service tag identifying a voice network address to which a voice connection can be established;

providing, on the display device, a displayed service object associated with the service tag;

selecting the service object with the input device;

upon selection of the service object, employing a voice communication module to establish a voice connection to the voice network address, retaining context information related to the data connection, and suspending the primary data connection; and

determining, based upon information stored with the service tag, physical capabilities of the communication terminal device and physical network connections to the communication terminal device, whether simultaneous voice and data communication is possible;

establishing a secondary data connection to a data network address identified by the service tag if it is determined that simultaneous voice and data communication is possible;

upon completion of the voice communication using the voice connection, terminating the voice session, terminating the secondary data connection if one has been established, and resuming the primary data connection.

16. A method, according to claim 15, wherein:

the voice connection and the secondary data connection are both made to a service provider.

17. A method, according to claim 15, wherein:

the voice connection and the secondary data connection are both accomplished using one physical network connection.

18. A method, according to claim 15, wherein:

the voice connection and the secondary data connection are accomplished using more than one physical network connection.

19. A method, according to claim 15, further comprising:

receiving network navigational information via that secondary data communication connection.

20. A method, according to claim 15, wherein:

data communication via the secondary data connection is remotely guided.

21. A method, according to claim 15, further comprising:

receiving, via the secondary data connection, a resumption network address.

22. A method, according to claim 21, further comprising:

establishing a data connection to the resumption network address upon resumption of the primary data connection.
