Abstract
To address the need for an apparatus and method for handoff from a cellular wireless network to a non-cellular wireless network (WLAN, e.g.), the present application describes an access gateway () and a dual mode mobile station () that enable such handoffs. The MS provides information to the access gateway so that it can initiate a handoff with the serving cellular MSC (). By triggering handoffs in this manner, cellular networks need not have special information about non-cellular networks to support handoffs. Instead, dual mode MSs can determine when a handoff to a non-cellular network is preferred and request a handin () from the non-cellular network.
