The conference on day 2 started with a session on “Competing Mobile Broadband Access Network Technologies” chaired by Thomas Haustein, Fraunhofer HHI, and addressed challenges emerging with the introduction of LTE and EPC. The second session “Access Network Integration and Service Enabling” chaired by Hans Schotten, University of Kaiserslautern, addressed technical problems during the deployment of EPC into existing network infrastructures in particular IMS roaming and different QoS signaling as well as the complex IMS & EPC interoperability, which might take until 2014/2015. A vendor panel “Standards, Products, and Business Cases for Future Seamless Communication” chaired by Thomas Magedanz, TU Berlin, discussed the LTE business case, Voice over LTE, the importance of open APIs for VoLTE and RCS, etc. The fourth session on “FUSECO Telco Applications: Voice, RCS and More” chaired by Hans Joachim Einsiedler, Deutsche Telekom Laboratories, addressed mobile broadband services and M2M opportunities, application challenges regarding fast deployment of Web services and slow agreement on interoperability. The overall tenor forecasts no LTE/mobile broadband killer application. The last session “FUSECO OTT Applications: Beyond Smart Bit Pipes” chaired by Thomas Michael Bohnert, SAP Research, presented opportunities for wholesale and enterprise operators, Over-The-Top (OTT) services and the usability LTE for vehicles. VoIP in mobile networks is growing in acceptance, increasingly challenging the operators around the globe. As Facebook has now announced interworking with Skype, the question of using Facebook as main interface for launching new applications in the future, has been raised.
