Abstract: The trends of wireless data networks and two main technologies GPRS and IEEE 802.11 WLAN are introduced. It also introduces the scheme to support mobility in these two networks and analyzes the Mobile IP handoffbetween the hybrid networks. A new handoff scheme is proposed to reduce the handoff delay, packet loss and to prevent the ping-pong effect utilizing the dwelltimer and multi-tunnel technology.

Key words: hybrid network, general packet radio service, IEEE 802.11, mobile IP, handoff
