Mobile users are facing the fact that many heterogenous radio access technologies coexist, ranging from wireless LANs to cellular systems. No technology has emerged as a common and universal solution which makes the current trends today toward the design of all-IP wireless networks, where radio cells are under the control of IP access routers for signalling and data transmission. In such networks, an IP-device with multiple radio interfaces or software radio can roam between different radio networks regardless the heterogeneity of their radio access technologies. The design of an all-IP wireless network requires an efficient and flexible handover management. A major issue in handover control is reducing data losses and avoiding additional end to end transmission delays. In this paper we propose mechanisms to handle soft-handover management in the IP layer which can coexist with mobile IPv6 and allow efficient micro mobility management.
