Hello Javier,

Well, if we take a step back to goals, I would like first to point that going Full MVNO might not be the best solution for us (roaming alone seems like quite a hassle, not to mention handsets management).

My focus here is narrower, as I am mostly trying here to assert what the possibilities for the core are, and if there are reasonable alternatives to the fully integrated solutions of the big providers.

That being said, I am not sure how our specific goals here would impact much the architecture: aren’t there a lot of constraints due to the 3GPP requirements?  It seems to leave little room for creativity.

To provide a bit of context and answer you:

We are historically providing solutions on fixed networks, with a strong bend toward business end-users. We are also used to have a lot of control over our architecture, most of our services running over open-source and/or in-house solutions.

Being able to provide our services on mobile accesses is now a necessity. For this we already are light MVNO, using two different MNOs. Thanks to forced routing, it mostly does the job regarding voice. Data could be managed also. SMS is proving trickier.

But each MNO have their own products set: building offers that would work on both is tedious and necessitate compromises that tend to make our marketing people unhappy. Not to talk about supporting two provisioning chains, two SIMs supply chains, etc… These problems would only get worse if we add other MNOs to the mix.

We are also stuck with the roadmap of the MNOs (VoLTE and VoWifi are but distant “maybe later” possibilities).

So, in one word, this is about autonomy. And its cost.

Regards,

Dario Renaud
