| 摘 要： | IntroductionMobility as an essential characteristic of wire-less network has received considerable attention inrecent years.A number of system- specific solu-tions have been developed for2 G( such as GSM)and 3G( such as UMTS) wireles networks.Fromthe Internetpointofview these solutions can be re-garded as layer- 2 solutions for wireless access net-works working transparently to the layer- 3 ( IPlayer) 1] .The evolution of wireless network is be-ing strongly influenced by mainly two compo…

| Abstract: | This paper proposed an optimized fast handoff scheme for real time applications in next generation IP based CDMA wireless networks. The idea is to utilize optimized IP multicasting handoff (based on PIM SM), which is triggered by CDMA layer 2 functionality. An IP based cellular network model with WCDMA FDD air interface and IP based packet traffic is adopted. No special network entities and signaling for handoff are added in our network model. The simulation results show that low delay and low packet lost rate can be obtained. |
