Advances of diverse wireless access technologies are

defining the trends of future wireless networks, named Next

Generation Wireless Networks (NGWN), where several access

technologies will coexist and devices will be equipped with

different network interfaces, in order to take advantage of each

access technology. In NGWN communication maintenance is a

concept willing to reach. Therefore, strategies to tackle

mobility and multihoming issues are required. In this paper we

propose an extension of HIP in order to cover challenges that

end to end mobility presents in NGWN. Our approach consists

on sending access technology related information before

handover execution occurs, in order to optimize handover

process. Moreover, the extension tackles QoS issues by sending

application requirements as well as restrictions or

improvements affecting its performance in the new access

technology.
