| Outline of Final Research Achievements |
The virtual single cell net means a small cell net which allows smooth packet transfer to moving terminals as if they stayed in a single cell. Small cells are contiguously deployed over roads, and connected with backhaul using PON (Passive Optical Network) drawing large latency. Each terminal is closed in an LMC (Logical Macro Cell) which consists of a few numbers of adjacent cells around the cell with the target terminal, and LMC is handed over to follow moving terminal. This research examines handover the 3G-LTE based procedures for the small cell net. Taking advantage of LMC, some information like an identifier for interruption to the target base station for handover is prepared before the handover action. If a terminal notifies directly handover to the target base station using requesting interrupt at the instance of the handover necessity, the interruption due to handover is very small, and comparable to the packet transfer cycle.
