The next-generation wireless networks are evolving toward an IP-based network that can provide various multimedia services seamlessly. To establish such a wireless mobile Internet, the registration domain supporting fast handoff is integrated with the DiffServ mechanism. In this paper, a Distributed-request-based CDMA DiffServ call admission control (CAC) scheme is proposed for the evolving mobile Internet. Numerical examples show that the forced termination ratio of handoff calls is guaranteed to be much less than the blocking ratio of new calls for a seamless fast-handoff while proposed scheme provides quality of service guarantee for each service class efficiently.
