3GPP data in mysql radacct table

Hi, I have activated a freeradius server to collect accounting info from a GGSN. The server is up and running and storing "GPRS-PDP-Context” data in to the radacct table. However there are some important 3GPP fields that aren’t written to the table. for example we want to store the 3GPP-IMSI-MCC-MNC and 3GPP-Location-Info data in the DB. Is it possible to configure the sql_log to write this info into the DB? and obviously this would require also to add the fields to the table. In addition is there a function to translate the 3GPP-Location-Info from hex to decimal data? Thanks in Advance. Liran
