Admission　control　in　high-speed　train　communication　system　is　quite　different　from　admission　control　in　traditional　cellular　networks.　Conventional　admission　control　strategies　cannot　be　directly　applied　to　this　special　communication　scenario.　In　this　paper,　the　problem　of　admission　control　for　handover　service　is　investigated　in　high-speed　train　communication　environment.　An　admission　control　scheme　considering　bit　error　rate　(BER)　and　bandwidth　borrowing　strategy　is　proposed.　On　the　basis　of　admission　control　decision　rule　taking　BER　into　account,　a　part　of　bandwidth　obtained　by　compressing　variable　rate　service　in　the　networks　is　provided　for　handover　services.　The　admission　control　scheme　can　admit　handover　services　as　more　as　possible　while　it　guarantees　the　lowest　data　rate　of　different　services　in　the　networks.　Simulation　results　show　that　the　proposed　admission　control　scheme　has　a　better　performance　than　existing　admission　control　schemes.　©　2015,　Shanghai　Jiaotong　University　and　Springer-Verlag　Berlin　Heidelberg.
