ABSTRACT:
In mobile communication system100according to the present invention, mobile station1is camped on cell C10established by base station B10. In the cell C10, there exist indoor cells C11-C13and outdoor cells C21, C22as neighboring cells. Mobile station1measures received levels of cells C10-C13, C21, C22and determines cell types of the respective cells, i.e., whether each cell is an indoor cell or not, based on broadcast information M1. Mobile station1selects a cell as a reselection target on the basis of the received levels and cell types.
