High-bit-rate packet transfer to fast mobile terminals in an IP based micro-cellular network with parallel polling scenario

This paper presents an all IP based nucro-cellular network configuration used in the metropolitan area. aims to provide high-bit-rate pocket transfer to fast-moving terminals. With the high transfer rate and guaranteed security, it can be considered as the extension of corporate LAN for business uses. For ovoiding contention based occess delay and packet re-transfer delay during handover, a new parallel polling scenario is proposed. Operating within the range of Logical Marco Cell (LMC), detailed packet transfer procedures of polling are explained. Also automatic switching-over of LMC that locate Mobile Terminal (MT) at the center cell of LMC all along can reduce the burden of strict time frame faced by the MT during high frequent handover between micro-cells.
