By　means　of　exposing　the　intrinsic　relationship　between　home　Ambient　Intelligence(AmI)application　system　and　its　base　network　infrastructure,　the　paper　puts　forward　a　solution　of　adaptive　home　AmI　network　infrastructure　by　using　6LowPANUPnP　and　OSGi　technologies.　The　novel　model　supports　heterogeneous　devices　dynamic　joining,　Multiple　Control　Center　automatic　switching,　uniform　service　&　controlling　and　has　good　mobility.　According　to　the　solution,　the　methods　for　implementing　the　architecture　and　its　sub-systems,　as　well　as　the　technology　theory　for　it　are　presented.　At　last,　a　prototype　system　based　on　Jn5139　6LowPAN　is　designed.　©　2009　Springer-Verlag.
