| 2 | |
| 3 | To determine geographic location estimates based on the serving cell, OsmoSMLC |
| 4 | needs preconfigured global positions by latitude and longitude, for each cell of |
| 5 | each BSC. |
| 6 | |
| 7 | On the `cells` configuration node, cell locations can be indicated by LAC and |
| 8 | CI, or by Cell Global Identity. The following example configures the position |
| 9 | for a cell by LAC 23 and CI 42: |
| 10 | |
| 11 | ---- |
| 12 | cells |
| 13 | lac-ci 23 42 lat 12.3456 lon 23.4567 |
| 14 | ---- |
| 15 | |
| 16 | The following example configures the position by a Cell Global Identity with |
| 17 | PLMN 001-01, LAC 2 and CI 3: |
| 18 | |
| 19 | ---- |
| 20 | cells |
| 21 | cgi 001 01 2 3 lat 34.5678 lon 45.6789 |
| 22 | ---- |
| 23 | |
| 24 | If a cell's latitude and longitude is not configured, all location requests for |
| 25 | subscribers served by that cell are answered by a BSSMAP-LE Perform Location |
| 26 | Response without a Location Estimate and LCS Cause "Facility not supported". |
