Data files

The ESR-Logic module requires 4 CSV files for the correct operation: a macro cell info file, a femto cell info file, an eutran cell info file and an IMSI-to-SK conversion table file. These files are loaded on module start, and later automatically every day at the preset time, or manually by user request in the menu.

When a data file is loaded, a log file is created. The log file has the name '<data_file_name>.log'.

When a data file set in the INI / [Advanced] / sXXXFile could be loaded successfully then the file is backed-up (copied) to a file named as '<data_file_name>.bak'.

If the data file could not be loaded then the SNMP trap error 'Could not load the most recent XXX file' is generated and the back-up file '<data_file_name>.bak' is loaded. If the back-up files could not be loaded either then the SNMP trap error 'Could not load the backup XXX file' is generated.

The SNMP trap error 'The [macro|femto|eutran] cell info file is out of date' is generated when any of the last loaded cell info files has a date older than specified in the INI file ([CellInfo]/wMaxAgedays).

The format of the files is CSV, where the separator character is actually a semicolon.

Macro cell info file

Each line consists of the following fields:

LAC;CI;coord_X;coord_Y;startAngle;stopAngle;inRadius;outRadius

Femto cell info file

Each line consists of the following fields:

LAC;CI;Address_line1;Address_line2;Address_line3;Address_line4;postcode

E-UTRAN cell info file

Each line consists of the following fields:

TAC;ECI;coord_X;coord_Y;startAngle;stopAngle;inRadius;outRadius

IMSI-to-SK table file

Each line consists of the following fields:

IMSI_prefix;SK

The table is searched linearly from top to bottom, i.e. the first matching IMSI_prefix is considered as the search result.

Program termination

To quit the module gracefully, press the 'Close' button or Alt+F4 keys once, confirm the quit request and wait until the message box with the text 'Ready to quit' appears.

To quit the module immediately press and confirm 'Close' twice. In this case the pending call notifications will be lost.
