Abstract

A method and system for providing ubiquitous coverage and seamless connectivity for devices which supports internet access 215 which via third generation cellular and IEEE 802.11 wideband local area network (WLAN) technologies, irrespective of which radio access technology is available.

Claims (30)

1. A wireless system for facilitating seamless network connectivity, the system comprising:
(a) an integrated terminal including:
(i) a first access point (AP); and (ii) a wireless transmit/receive unit (WTRU) coupled to the AP via a first interface;
(b) a universal terrestrial radio access network (UTRAN) coupled to the integrated terminal via a second interface; and (c) at least one wireless local area network (WLAN) access device coupled to the integrated terminal via a third interface.
2. The system of claim 1 wherein the UTRAN provides the integrated terminal with access to an eternal network via the third interface.
3. The system of claim 2 further comprising:
(d) a second AP coupled to the WLAN access device via a fourth interface, wherein the WLAN access device provides the integrated terminal with access to the external network via the third and fourth interfaces.
4. The system of claim 3 wherein each of the second, third and fourth interfaces are wireless interfaces.
5. The system of claim 2 wherein the external network is the Internet.
