SGA - TACFAC/CEA database
("Sga-TACFACCEAdb")

• Basic operation
• User interface
• Configuration
• Version history

• Processes incoming location information data from Sga-9009.NNN files
• Builds a database of TACFAC values (part of the International Mobile Equipment Identity (IMEISV)) and the used strongest encryption algorithm (A5/1..3) in memory
• Generates alarms when a mobile equipment uses a weaker encryption algorithm then it used last time. Alarms contain timestamp, IMEISV, IMSI, CellId and the currently used A5 algorithm
• Provides a cell based encryption algorithm list with the weakest and the strongest encryption algorithm
• Uses cell name list to append names to cell id's
• Connects to the IMSI-MSISDN database to get subscriber's identifiers
• Provides a TACFAC black list to exclude frequently used IMEISV values
