1. A wireless transmit/receive unit (WTRU) comprising:
- a first physical (PHY) layer component configured to communicate with a first network of a first network type, wherein the first network type is an IEEE 802 wireless network type;
a second PHY layer component configured to communicate with a second network of a second network type, wherein the second network type is not the first network type;
a first medium access control (MAC) layer component configured to communicate with the first PHY layer component;
a second MAC layer component configured to communicate with the second PHY layer component; and
an interworking component configured to communicate with the first PHY layer component, the second PHY layer component, the first MAC layer component, the second MAC layer component, and a higher layer component, andwherein the interworking component is configured to providea first service for managing and controlling link behavior, wherein providing the first service includes configuring a trigger at the first MAC layer component, the first PHY layer component, the second MAC layer component, or the second PHY layer component,a second service for processing link events received from the first PHY layer component, the second MAC layer component, the second PHY layer component, or the higher layer component, anda third service for processing network information received from the first PHY layer component, the second MAC layer component, the second PHY layer component, or the higher layer component.

Abstract
This invention relates to wireless local area networks (WLANs), and the interoperability of networks of different types or conforming to different standards, and to methods and apparatus to allow a multimode wireless transmit/receive unit (WTRU), which is able to operate in more than one type of network, to handover from one network type to another without adversely affecting service, utilizing a mechanism and information flows implemented in a new protocol stack.
