During the IFA Preview today in Munich, Deutsche Telekom confirmed that Windows Phone 7.8 will have Rich Communications Suite (RCS-e) functionality. The functionality was noted earlier in the leaked details and will come in the form of a separate application and integrated with Windows Phone 8. The RCS-e services will be a cross platform, cross network functionality Previously, RCS-e was announced during the Summit a few weeks ago for Windows Phone 8 but it's a technology that most people are not familiar.
In Deutsche Telekom's presentation they discussed using Joyn services that will provide chat, file transfer and video chat features between carriers. . Joyn will be interoperable between Orange, Telefonica and Vodafone networks for now with O2 Germany coming on board after launch.
The service will provide free chat and file transfers and charge for video chat. Commercial availability is planned for October. It will be interesting to see how the RCS-e services match up with existing services such as Skype. Equally interesting will be to see if the U.S. Carriers can play nice to establish such interoperability.
We've seen things like this before--think Sprint's horrid proprietary PictureMail years ago--but RCS-e at least sets some standards. Personally we think 3rd party services like IM+, Kik, Nokia's Pulse and others are the future but we're glad to see Windows Phone 7.8 getting it too, it should make carriers a little more inclined to support Windows Phone.
