Example 2 with Import

use of com.secupwn.aimsicd.data.model.Import in project Android-IMSI-Catcher-Detector by CellularPrivacy.

the class RealmHelper method checkDBe.

/**
 * This is the {@link Import} data consistency check wich checks each
 * imported BTS data for consistency and correctness according to general
 * 3GPP LAC/CID/RAT rules and according to the app settings:
 * <p/>
 * tf_settings         (currently hard-coded)
 * min_gps_precision   (currently hard-coded)
 * <p/>
 * So there are really two steps in this procedure:
 * a) Remove bad {@link Import Imports} from Realm
 * b) Mark unsafe {@link Import Imports} with "rej_cause" value.
 * <p/>
 * The formula for the long cell ID is as follows:
 * Long CID = 65536 * RNC + CID
 * <p/>
 * If you have the Long CID, you can get RNC and CID in the following way:
 * RNC = Long CID / 65536 (integer division)
 * CID = Long CID mod 65536 (modulo operation)
