thoughts about incorporating credit / billing in D-GSM
it is not a priority to really implement a working setup, but we should have a bit of a plan for the future, to not block progress later.
- how could credit management be standardized?
- how to handle link loss? keep a set amount of credit on each site to use even if the subscriber's home village is unreachable?
- think about credit for: voice, sms, data connections.
- Look at DIAMETER accounting specs, CCR / CCA https://en.wikipedia.org/wiki/Diameter_Credit-Control_Application
