The research of interaction management based on the IPv6 wireless mobile terminals

The packer switching service of the third-generation mobile communication network (3G) has provide a broader range of services, while wireless local area network (WLAN) has a faster speed in information transmission, thus making these two complementary functionally. However, with the improvement of technology and increasing of mobile users, it has a significant impact on network communication when switching the networks which result in handover latency, although the different networks allow mobile users roaming between different IP networks; furthermore, it will lead to care-of-address of mobile users error caused by the failure of agent information return if the users move too fast. This thesis basically studies on mobile terminals in the WLAN and 3GPP, two different networks using a wireless IPv6, aiming at proposing a to reduce switching delay and position error.
