摘要：

In　heterogeneous　wireless　networks　(HWNs),　HWNs　are　formed　by　integration　of　different　communication　technologies,　to　support　high　QoS　services　anywhere　and　anytime.　Joint　call　admission　control　(JCAC)　is　suitable　for　HWNs.　An　optimal　JCAC　strategy　for　HWNs　based　on　new　calls　and　handoff　calls　was　proposed　in　this　paper,　to　analyze　the　network　resource　utilization　and　the　QoS　parameters,　and　the　algorithm　of　value　iteration　was　improved　by　using　multi-dimensional　threshold　structure.　Finally,　the　performance　of　the　proposed　model　was　evaluated　by　simulations.　Ths　simulation　results　show　that,　it　can　provide　high　quality　of　service　and　minimize　the　cost,　and　the　strategy　has　better　efficiency　and　effectiveness　in　application.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
