      IMS World Forum 2012 – Clouds in the IMS Fields

      This year the IMS World Forum took place in Madrid, in a venue just a hundred meters away from the Santiago Bernabeú Stadium and at the same time of the Champions League semifinal game between Real Madrid and Bayern Munich. The Real Madrid player that shot the last penalty gave an indication about the discussions taking place in the IMS World by sending the ball to the Cloud. The main discussion topics during the show were IMS Cloud, IMS complexity and RCS-e; but what’s behind those discussions is without a doubt the Over-The-Top (OTT) threat and how to deal ...

      RCS-e Spanish Launch – a Joyful Response?

      RCS-e has made the news: newspapers (read here, in Spanish) and radio stations are announcing today the launch of “Joyn”, the initiative that “wants to kill WhatsApp” (this is the literal translation of the article title) from the Spanish mobile service providers  (Telefónica Movistar, Vodafone and Orange). “Joyn” is based on the Rich Communications Suite specification, which defines how mobile service providers can provide instant messaging (IM), file transfer and video sharing applications from their core networks.  Not yet official, the brand “Joyn” is intended to be used across Europe. There are several important remarks to be made on this ...

      MetroPCS' voice over LTE Hail Mary

      The awful first quarter results which MetroPCS posted last week underscore a problem facing CDMA carriers as they migrate to LTE, and it's no surprise that MetroPCS is staking its rebound on voice over LTE (VoLTE) smartphones that it hopes to debut in the second half of the year.

    3. Joyn is SMS version 2.0, but will it help carriers stem the OTT tide?

      Explore FierceWireless (Mar 29 2012) RCS

      Joyn is SMS version 2.0, but will it help carriers stem the OTT tide? Remember SMS? Wireless carriers sure do. Text messages cost 10 cents each and require virtually nothing in the way of network resources. Compare that with the falling price of a MB of data and the rising expenses associated with pacing users' demands for data connections. Wireless carriers loved the solid profits that SMS used to deliver--and that's why they're rallying around joyn. Announced at this year's Mobile World Congress trade show, joyn is the marketing name given to the GSMA's Rich Communications Services effort. RCS has been around for years--the standard is now heading into its ... (Read Full Article)

      T-Mobile USA's Brad Duea explains Bobsled's accelerating momentum With over-the-top voice and data services emerging as a major disruption to conventional carrier business models, T-Mobile USA decided that if you can't beat 'em, you may as well join 'em. Last spring, the operator introduced Bobsled, which enables users to place free Internet calls over almost any data connection across devices including iOS and Android smartphones and tablets. On the eve of the recent CTIA Wireless 2012 conference, T-Mobile announced that more than a million consumers are using Bobsled services, which are available to consumers on any wireless operator network across the globe--in fact, 95 percent of Bobsled ...

      VoLTE subscriptions to hit 2 million by 2013 The Voice over LTE (VoLTE) market is set for unparalleled growth over the next four years, reveals a recent report from ARCchart. The research firm estimates that there will be as many as 74 Million VoLTE enabled subscribers at the end of 2016. While this figure is a far cry from mobile VoIP subscriptions based on Over-the-top (OTT) applications such as Skype (which is forecast to hit 510 million subscriptions by the same time), it will represent as many as 10 % of all LTE subscriptions.

      Is video the future of voice? Telephone voice quality has remained essentially unchanged for a century, seemingly immune to the advances in technology that have relentlessly occurred (and continue to occur) around it. Of course, there's more to the story than that — telephone lines have moved from analog to digital and audio codecs have become more efficient over time — but the goal has always been to reduce the amount of bandwidth required to transmit voice at roughly the same quality, not to improve it. "There's not a grea (Read Full Article)

      I got an SMS this morning from a business contact - actually a client from an operator who came to the Telco-OTT workshop a couple of weeks ago. It was an invitation to download TU Me, the new Telefonica VoIP and messaging app, sent from within the app itself.But as it happens, I've already got the app on my phone. But what I don't have on my phone is this person's phone number. So I can't connect to them. And so TU Me didn't realise we already knew each other.This got me thinking. A ... (Read Full Article)
