Back in 2009, as the anticipation for LTE was building, some companies in the mobile industry started a campaign to address a minor, oft-overlooked hole in the migration to LTE – telephony.
As is well known today, as an all IP packet environment, LTE was intentionally designed to *not* support any of the ‘old’ circuit voice/SMS services. The idea was to ________ (fill in the blank: encourage? force? coerce? incent?) mobile operators to invest in a entirely new, duplicate voice/SMS core infrastructure.
One group, dreaming of a bucolic, ‘lazy river’ approach to network transformation, created the VoLGA Forum. The VoLGA Forum embraced a pragmatic approach toward evolving to an all IP access network: harness an existing 3GPP specification to bridge the old circuit voice system onto the new LTE network and giving time for the brand new all-IP voice system to mature.
And there was a different dream - more dramatic, more pizzazz , more of a ‘leap of faith’. Leave the old circuit network behind and we'll all jump with full faith onto the new, as yet undefined (at the time) system.
Well, reports are coming back from the LTE World Summit, held this week in Barcelona, that perhaps the ‘leap’ is a bit longer than anticipated – a lot longer.
"If you haven't built the perfect data network for OTT players, then you have more time," said Ove Andreasen,director of mobile systems for Danish operator TDC A/S stated during the LTE event. "You could argue we're too late now if they stay as strong as they are."
Looks like we'll have to dream a little longer...
