| 1102 | Beijing |
| ...... | Beijing |
| 1145 | Beijing |
| ...... | ...... |
| 1205 | Tianjin |
| ...... | Tianjin |
| 1225 | Tianjin |
| ...... | ...... |
From the table of the T_LAI shown in the table 1, as can be seen, the LAI that is designated 1100-1145 is corresponding to the Beijing area, and 1205-1225 is corresponding to Efficiency in Buildings in Tianjin Area.Corresponding relation in the look-up table promptly can be determined the pairing ownership place of the LAI that obtains.For example, suppose that the current LAI that obtains is 1205, the corresponding relation in the look-up table 1 can determine that the pairing ownership place of this LAI is Tianjin.
After the broadcast message that sends by the base station was obtained LAI information, smart card both can be after the LAI information that receives the portable terminal transmission, triggered the operation of searching corresponding relation; After also can being the LAI in upgrading the 6F7E file, trigger the operation of searching corresponding relation, that is to say, when smart card find the current LAI that obtains with obtain before, be kept in the 6F7E file LAI not simultaneously, trigger this search operation.
