Hi, I apologize in advance if I'm in the wrong place, just a lonely ranger looking for answers on the grand www, will appreciate redirects, thank you.
I'm a DevOps at a small cellular provider, in charge of the infrastructure of the internet service for mobiles.
We have a couple of Cisco 7206 routers running as GGSNs, and I'm trying to get the data (not voice) session info sorted out for billing needs. specifically, amount of in/output of octats or bytes for each mobile session. I've tried a few accounting methods with an external freeRADIUS server to no avail - there're a lot of great tutorials for login accounting and voice CDR accounting out there, but little in the way of mobile data recording/accounting.
I get logs on the RADIUS for users+passwords logging into the router, but no IMSI/PDP-contexts/GPT information of any kind.
After a long search I added the gprs charging function to my config:
gprs default charging-gateway [RADIUS server ip]
still nothing on the external RADIUS server.
My questions are:
1. Is something just missing on the 7206 config? if so what can it be? Is RADIUS the right tool on the server side to collect the info I need?
2. Am I way off track? What would be the best way to get records of the amount of data per session?
3. Should I be looking for this info on a different piece of the infrastructure?
Many thanks and again, if I've strayed into the wrong place, will greatly appreciate a redirection.
