| Abstract: |
| A dual-mode terminal model that can perform intelligent handoff betwe
en 3G and WLAN is designed. In order to realize seamless handoff between the t
wo networks, a network interface selection algorithm is proposed. By pre-regist
ration and pre-authentication in the algorithm, vertical handoff delays are redu
ced. Moreover,pre-handoff is used in order to reduce packets loss during the ve
rtical handoff period. A good performance of the design and algorithm is verifie
d through simulation. |
