683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 20.21.1.1 Definition | Cell selection is a process in which a MS, whenever a new PLMN is selected, attempts to find a suitable cell of that PLMN to camp on. Two methods of searching for a suitable cell are possible, normal cell selection and stored list cell selection. The process ensures that the MS is camped on a cell from which it can rel... |
