Abstract

The present invention provides for a system and method for sharing user event information (such as, and without limitation, presence on a network) among mobile (wireless) devices and those connected to fixed IP networks such as the Internet. In accordance with embodiments of the invention, the system and method support instant messaging between wireless devices and fixed IP network devices and between wireless devices and other wireless devices. The term wireless device is used broadly to include cell phones, laptop computers with wireless modems, wireless PDAs, and any other remote wireless devices.

Claims

1. A method of determining presence for a specific wireless device associated with a wireless telephone network, the method comprising:

sniffing a signal passing between a BSC and an MSC of the wireless telephone network indicating the presence of the specific wireless device on the wireless telephone network;

broadcasting, over a second network, a signal indicating presence of the specific wireless device; and

providing, over a third network, the signal indicating presence of the specific wireless device.

2. The method of determining presence of claim 1, wherein the signal passing between the BSC and the MSC of the wireless telephone network further indicates location.
