Abstract: Absolute positions of global position system (~GPS~) enabled mobile communications devices, which form a wirelessly networked group of GPS  mobiles, can be determined at each of the mobiles based on use of wireless communications capabilities of the mobiles for obtaining relative positioning information or range measurements for the mobiles of the group. Although the mobiles of a group cannot establish line of sight (~LOS~) communications signal reception paths with a sufficient number of GPS satellites to permit each mobile to determine its absolute position solely based on GPS signal transmissions, the mobiles can compute their respective absolute positions and the absolute positions of other mobiles if a predetermined number of LOS paths can be established and based on the obtained range or relative positioning information.

Patent CA-2512864-A1 (CA)
Inventor: LOVE ROBERT T
IPC: H04L12/56
Filed: 2004-01-20
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 (214) and a dual mode mobile station (201) that enable such handoffs. Dual mode MSs can determine when a handoff to a non-cellular network is preferred and request a handin (302) from the non-cellular network. The access gateway provides information to the MS (304) so that it can initiate a handoff through the serving cellular network.  Triggering handoffs in this manner, allows cellular networks to handle handoffs to non-cellular networks in much the same way they handle inter-MSC  handoffs today, i.e., source initiated.
