Abstract

Wireless access protocol-capable wireless devices are able to synchronize displayed Web content. A first WAP device requests a synchronized session through the sync Proxy of the network. The sync Proxy, through a WAP Push Proxy, sets up the synchronized session. One or both wireless devices may then request content from a Web site. This content is transmitted from the Web site to the first device, and through a WAP proxy to the second device.

Claims

1. A method for establishing a synchronized Web content session between a plurality of mobile devices in a network comprising first and second Wireless Access Protocol (WAP) Proxies and a Push Proxy Gateway, the method comprising the steps of:

the first WAP Proxy receiving from a first mobile device of the plurality of mobile devices a synchronization initiation signal;

the first WAP Proxy transmitting a Push Access Protocol signal to the Push Proxy Gateway;

the Push Proxy Gateway transmitting a Push Service Indication signal to a second mobile device of the plurality of mobile devices;

the second mobile device transmitting a synchronization accept signal to the second WAP Proxy;

the second WAP Proxy transmitting a synchronization acknowledge signal to the first mobile device;

the first mobile device transmitting a Get command, comprising a Universal Resource Locator, to the first WAP Proxy;

the first WAP Proxy transmitting the Get command to the a World Wide Web server;

the first WAP Proxy transmitting a Push Service Loading signal to the Push Proxy Gateway;

the Push Proxy Gateway transmitting the Push Service Loading signal to the second mobile device;

the second mobile device transmitting a Get signal, comprising the Universal Resource Locator, to the second WAP Proxy;

the second WAP Proxy transmitting the Get signal to the World Wide Web server;

the first WAP Proxy receiving a first Get response signal, comprising Web content, from the World Wide Web server;

the second WAP Proxy receiving a second Get response signal, comprising the Web content, from the World Wide Web server; and

the first and second WAP Proxies transmitting the first and second Get response signals to the first and second mobile devices respectively.

2. The method of claim 1 wherein the first and second Wireless Access Protocol Proxies are Push Initiators.

3. The method of claim 1 wherein the step of the Push Proxy Gateway transmitting a Push Service Indication signal includes the Push Proxy Gateway transmitting the Push Service Indication signal to the plurality of mobile devices.

4. The method of claim 1 further comprising:

initiating a voice call between the first and the second mobile devices.

5. The method of claim 1 further comprising:

the first WAP Proxy receiving a terminate synchronization session signal from the first mobile device;

the first WAP Proxy transmitting a Push signal to the Push Proxy Gateway;

the Push Proxy Gateway transmitting a Push Service Indication signal to the second mobile device;

the Push Proxy Gateway receiving a confirmation signal from the second mobile device;

the Push Proxy Gateway transmitting the confirmation signal to the second WAP Proxy; and

the second WAP Proxy transmitting the confirmation signal to the first mobile device.

6. A method for establishing a synchronized Web content session between a plurality of wireless devices in a network comprising a Wireless Access Protocol (WAP) Proxy, a Sync Proxy, and a WAP Push Proxy Gateway, the method comprising the steps of:

the WAP Push Proxy Gateway receiving from a first wireless device of the plurality of wireless devices, through the Sync Proxy, a synchronization initiation signal;

the WAP Push Proxy Gateway transmitting a Push Service Indication signal to a second wireless device of the plurality of wireless devices;

the Sync Proxy receiving from the second wireless device a synchronization accept signal;

the Sync Proxy transmitting the synchronization accept signal to the first wireless device;

the Sync Proxy forwarding a Get signal, comprising a Universal Resource Locator and a first profile, from the first wireless device to a World Wide Web server;

the Sync Proxy receiving from the World Wide Web server, content that is tailored in response to the first profile;

the Sync Proxy transmitting the tailored content to the first wireless device;

the Sync Proxy transmitting to the second wireless device, through the WAP Push Proxy Gateway, a signal comprising the Universal Resource Locator;

the second wireless device transmitting to the World Wide Web server, through the Sync Proxy, a Get signal comprising the Universal Resource Locator and a second profile; and

the second wireless device receiving, through the Sync Proxy, content from the World Wide Web server that has been tailored in response to the second profile.

7. The method of claim 6 further comprising:

initiating a voice call between the first and the second wireless devices.

8. A method for establishing a one-way synchronized session between a plurality of wireless devices operating in a network comprising at least a first and a second Wireless Access Protocol WAP Proxies and a Push Proxy Gateway, the method comprising the steps of:

the first WAP Proxy receiving a synchronization request signal, comprising a first profile, from a first wireless device;

the first WAP Proxy transmitting a Push signal to the Push Proxy Gateway;

the Push Proxy Gateway transmitting a Push Service Indication signal to a second wireless device;

the first WAP Proxy receiving a synchronization accept signal, comprising a second profile, from the second wireless device;

the first WAP Proxy transmitting the synchronization accept signal to the first wireless device;

the first WAP Proxy receiving a Web content request signal from the first wireless device;

the first WAP Proxy forwarding the Web content request to a Web server;

the first WAP Proxy receiving the Web content from the Web server;

the first WAP Proxy formatting the Web content for the first and second wireless devices based on the first and second profiles;

the first WAP Proxy transmitting a Push signal to the second wireless device, through the Push Proxy Gateway;

the second WAP Proxy receiving a request for the Web content from the second wireless device; and

the first WAP Proxy transmitting the Web content, in appropriate formats, to the first and the second wireless devices in response to requests from the respective wireless devices.

9. The method of claim 8 and further including the step of initiating a voice call between the first and the second mobile communication devices.

10. The method of claim 8 wherein the first WAP Proxy is a push initiator and comprises transcoding capabilities.

11. A method for establishing a synchronized Web content session between a plurality of wireless devices operating in a network comprising a Wireless Access Protocol (WAP) Proxy and a Push Proxy Gateway, the method comprising the steps of:

the WAP Proxy receiving a synchronization initiation signal from a first wireless device of the plurality of wireless devices;

the WAP Proxy transmitting a Push Access Protocol signal to a second wireless device through the Push Proxy Gateway;

the second mobile device transmitting a synchronization accept signal to the WAP Proxy;

the WAP Proxy transmitting a synchronization acknowledge signal to the first mobile device;

the WAP Proxy receiving a Web content request signal from the first wireless device;

the WAP Proxy transmitting the Web content request signal to a Web server;

the WAP Proxy receiving the Web content in response to the request signal;

the WAP Proxy transmitting the Web content to the first wireless device;

the WAP Proxy transmitting a Push signal to the second wireless device through the Push Proxy Gateway; and

the WAP Proxy transmitting the Web content to the second wireless device in response to a received request for the Web content from the second wireless device.

12. The method of claim 11 further comprising:

initiating a voice call between the first and the second mobile communication devices.
