Mobile devices with the ability to access IEEE 802.3, 802.11, 802.16 and cellular networks in various combinations are driving the need for seamless session continuity and IP address continuity when transitioning between these networks. An approach to facilitating service transition based on triggering and providing network detection and selection assistance is being followed in the IEEE 802.21 working group. This paper presents some of the issues and proposed approaches.
