Well, now that there is a study, it’s true. When asked what constitutes fixed-mobile convergence service, 75% of the respondents in a recent study proposed by FMC vendor Outsmart said dual mode handsets (DMH).

But FMC can mean many things, others mentioned in the survey include single billing (34%), a home zone rate plan (27%), voice mail convergence (13%) or a “Skype-like” solution (9%).

I think the funniest one in the list is the homezone rate plan, which presumably is the concept of giving consumers lower cost mobile calling when they are in a certain cell zone in their homes. This is, of course, a completely cellular solution with no reliance on the fixed network, ironic in an FMC survey.

We here at UMAToday have discussed the differences of FMC and FMS in the past. The conclusion was that UMA fits into either camp. So if DMH = UMA, and DMH = FMC, then UMA must equal FMC.

Given that FMC is being viewed as the business case driver for IMS, and now we know that DMH = FMC, it’s no wonder why there is so much pressure to get the pending VCC specification completed. VCC is the specification to make DMH work which equals FMC which is the business case driver for IMS.

The math is getting pretty complicated.

For some reason, I thought FMC was about helping operators lower operational costs by bringing disparate fixed and mobile networks together as well as providing a common service architecture. I guess it’s simpler than that, FMC = DMH.
