A Wiggling Adjustment Model for Radio Access Network Cell Coverage

In order to provide seamless communication service, cell overlap is necessary for radio access network. But too many cell overlaps lead the waste of network resource. To reduce the waste and hold the reasonable cell overlaps, a model named WAMRANEC (Wiggling Adjustment Model for Radio Access NEtwork Cell coverage) is shown. Firstly, three factors concerned coverage optimization are analyzed. Then the central cell is confirmed according to the densities of overlaps and of mobile users. And the algorithm is given to optimize the cell coverage. At last, WAMRANEC is used to the scenario of cell outage self-healing. The simulation shows the process of optimization when using WAMRANEC.
