Following my previous blog on the Fraunhofer FOKUS IMS event, here are some more insights from that event which you will find useful ..
Roberto Minerva of TIM Research asked the question – Why don’t we think of ftp to a SIM card? And indeed .. Why not? Applications like these are truly innovative. However, most Operators approach IMS and IP with the ‘hammer’ they are most familiar with – on the principle that “If all you have is a hammer, everything looks like a nail.” Hence we see a proliferation of voice IMS applications(where the ‘hammer’ is the voice) when we should see data
Malcolm Wardlaw(Director converged services BT 21CN ) said that many services can be implemented at a Web 2.0 layer(and strictly an IMS layer is not necessary). However, not all services can be implemented only from a Web stack. Hence, there will be always some need for telephony services – where IMS wins. This may be especially true of services that combine voice and data. Also, Identity will be a key area and a key plus point for IMS. Thus, while many services may not need the IMS stack .. But there will be some services which can’t be developed without the IMS stack and in addition, some services will command a premium by being able to provide a better class of service than the others.
The emphasis on Identity has always been the domain of Jörg Heuer Deutsche Telekom Laboratories – whose work I follow with interest and who was also a speaker at this event.
Speaking of IMS stack, Stefan Holtel. Vodafone Group R&D – D Munich raised the question of an Open IMS. He also questioned why IMS is not a part of the LAMP stack i.e. if we want to attract internet developers, then presumably we should be a part of the LAMP stack and open? The unfortunate situation today is: we see IMS developers almost exclusively confined to the vendor community .. Which is sad .. And which defeats the purpose.
Finally, there is the question of end to end IMS and SDP. End to End IMS is not an easy proposition since both Operators need to have IMS .. However, ironically many applications need end to end IMS(video calling). Hence, SDP may provide some elements of end to end working for IMS ..
More on all this soon ..
Any questions/comments welcome
