Abstract

A communication system in accordance with the present invention includes at least one network appliance device (3415) which is coupled to a network (3402). The network appliance device (3415) includes software for detecting incoming calls and initiating call sessions in accordance with a signaling protocol. The system further includes a wireless communication gateway (3410) coupled to the network (3402) for allowing the network appliance device (3415) to communicate in accordance with a wireless network protocol. The wireless communication gateway (3410) includes, or is coupled to, a communication proxy (3405) for translating messages between the signaling protocol and the wireless network protocol. In one exemplary embodiment the signaling protocol takes the form of the Session Initiation Protocol (SIP) and the wireless communication protocol takes the form of the Wireless Application Protocol (WAP).

Claims

1. A communication system comprising:

a network appliance device coupled to a network, the device comprising software for detecting incoming calls and initiating call sessions in accordance with a signaling protocol;

a communication gateway coupled to the network, the communication gateway providing for communications between the network appliance and devices outside the network in accordance with a wireless communications protocol; and

a wireless communication proxy server coupled to the network for translating messages between the signaling protocol and the wireless communication protocol;

wherein the network appliance device comprises a display, and the network appliance device receives messages translated by the wireless communication proxy that relate to advertising content for output to the display.

2. The system of claim 1 wherein the signaling protocol is Session Initiation Protocol (SW) and the wireless communication protocol is Wireless Application Protocol (WAP).

3. The system of claim 2 further comprising at least one SIP proxy server coupled to the network for exchanging SIP messages with the network appliance device and with the wireless communication proxy server.

4. The system of claim 2 wherein the network appliance device and the wireless communication proxy server exchange SIP messages directly.

5. The system of claim 2 wherein a key stroke at the network appliance device is provided to the wireless communication proxy server as a single SIP request.

6. The system of claim 1 wherein the network appliance device receives messages translated by the wireless communication proxy server that relate to the advertising content for the display when no call is in progress.

7. The system of claim 6 wherein the network appliance device is configurable to allow a user to select the content displayed when no call is in progress.

8. The system of claim 1 wherein the signaling protocol is Session Initiation Protocol (STP).

9. The system of claim 1 wherein the wireless communication protocol is Wireless Application Protocol (WAP).

10. The system of claim 1 wherein the communication gateway and the wireless communications proxy server are an integrated system.

11. A method of communicating with a network appliance device in a network, comprising:

at the network appliance device, detecting incoming calls and initiating call sessions in accordance with a first protocol and receiving messages translated by a communication proxy that relate to advertising content for display at the device; and

using the communication proxy, to translate the messages between the first protocol and a second protocol to allow the network appliance device to communicate in accordance with the second protocol.

12. The method of claim 11 wherein the first protocol is Session Initiation Protocol (SIP) and the second protocol is Wireless Application Protocol (WAP).

13. The method of claim 12 further comprising using one or more SIP servers coupled to the network for exchanging SIP messages with the network appliance device and with the communication proxy.

14. The method of claim 12 further comprising directly exchanging SIP messages between the network appliance device and the communication proxy.

15. The method of claim 11 wherein the messages that relate to the adverstising content for display at the device are received when no call is in progress.

16. The method of claim 15 further comprising, at the network appliance device, allowing a user to configure the device to select the advertising content displayed when no call is in progress.

17. The method of claim 11 wherein the first protocol is Session Initiation Protocol (SIP).

18. The method of claim 11 wherein the second protocol is Wireless Application Protocol (WAP).

19. A communication system comprising:

a network appliance device coupled to a network, the device comprising software for detecting incoming calls and initiating call sessions in accordance with Session Initiation Protocol (SIP);

at least one SIP server coupled to the network for exchanging SIP messages with the network appliance device; and

a communication gateway coupled to the network for allowing the network appliance device to communicate outside the network in accordance with a wireless communication protocol;

wherein the network appliance device comprises a display, and the network appliance device receives messages translated by the communication gateway that relate to advertising content for the display.

20. The system of claim 19 wherein wireless communication protocol is the Wireless Application Protocol (WAP).
