To provide a QoS (Quality of Service) for mobile terminals in an all-IP environment requires a very extensive research. In integrated services networks, most of work is seeking to extend RSVP to a mobile environment. The paper describes a new procedure for resource reservation in the wireless environment. It is based on the application of QoS NSLP signaling, following the work of the IETF NSIS (Next Steps In Signaling) WG. This is primarily based on a reservation MSpec (Mobility Specification) object that determines the future locations of the terminal which is included in a mobility profile.
