Abstract

This paper describes practical tests and evaluation of different ways in which the session initiation protocol (SIP) could be used to assist application adaptation for IP applications during a vertical handover (VH), that is one between base stations that are using different wireless link technologies. Such an approach has been implemented on a software testbed based at the Centre for Telecommunication Research (CTR), King´s College London as part of a joint project with BTexact Technologies
