FASCIA format

The FASCIA format is a simple JSON format to exchange information from mobile network monitoring devices (such as IMSI catchers, passive analysis tools) into a common simple format and to be processed by FASCIA. The format can be used for GSM, UMTS/WCMDA or LTE networks.

Format

key	format	description
timestamp	datetime	timestamp in UTC when the event was captured
radiotype	string	Network type (such as GSM, UMTS/WCMDA, LTE)
sensor	string	a GUID representation of the sensor capturing the event
imsi	string	IMSI in the following format (270 01 60000000001)
tmsi1	string	An hexadecimal representation of the TMSI 1
tmsi2	string	An hexadecimal representation of the TMSI 2
imsi-country	string	country (if lookup available)
imsi-brand	string	operator brand (if lookup available}
imsi-operator	string	operator (if lookup available)
mcc	integer	mobile country code (MCC)
mnc	integer	mobile network code (MNC)
lac	integer	location area code (LAC) for GSM/UMTS or tracking area code (TAC) for LTE
cell	integer	Cell ID (CID) of the base transceiver stations (BTS) for GSM and LTE. For UTMS, this is the UTRAN cell id with the addition of the radio network controller (RNC).
unit	integer	Primary scrambling code (PSC) for UTMS. Physical cell id (PCI) for LTE. For GSM, the field is empty.
