Nice video, I have just one question. Where is the AuC (authentication center)?

[@paweljarosz83]

how come IMSI contains mobile phone unique ID? What does the SIM card know about the phone?

[@ferdzacosta]

[@Kestojah]

Could someone assist me with this please ?
When the call setup message reaches passes through the BSS and reaches the MSC and the call is place on hold, the subscriber details are validated. I would just like to verify which information is being validated at that point ? Is it the person calling or is it the number of the destination mobile device ?

[@a.s.karthikeyan9569]

From what I know, it's the source person's details which will be verified.
