From macrocell to microcell system to offer road communication to vehicle

In future, mobile multimedia services will become popular as widely as the use of the cellular phone today. It makes the bandwidth required for each multimedia service increase rapidly, and such kind of communication will be dominant since the development of machine-machine communications for human interactivity in the multimedia age. For this demand, the micro-cell will become a major role in substitution of the macro-cell. This paper proposes a new paradigm of mobile network system where a virtual single cell over connected micro-cells used to release the traffic load of macro-cells, and an IP-based paging network offering mobile users the seamless connection between networks through vertical handover functionality. New connected micro-cells network is to support vehicular users the broadband mobile services like mobile tele-medicine, teleconferences, online-game, etc and can be used for ITS (Intelligent Transport System) and shares the traffic load with the Macro-cell network. In order to become feasible, the first important issue need to be solved is mobility management because it is supposed to server for fast moving terminals. This paper also presents the virtual single cell mechanism; an LMC (Logical Macro Cell) and multi-polling to LMC to make resource reservation to adapt to quick change of access points of fast MT. Performance of achievements is reported to evaluate our proposal.
