Voice Over Mobile Broadband (VoMBB)
•VoMBB is an alternative and efficient method of transmitting traditional mobile circuit switched voice services as packet-switched over 3G/4G mobile broadband and effectively offload such services to voice over WiFi
VoMBB Definition
•VoMBB allows carriers to optimally leverage their IMS framework and manage the flow of mobile VoIP traffic generated by Over The Top (OTT) applications
Ecosystem & Economic of Scale
•VoMBB can potentially open up new models for charging of voice services and even possible relationships between carriers and OTT application developers for mutual benefits
Business Opportunities
•Global VoMBB service revenues increase is estimated to be $3 Billion in 2013 to nearly $103 Billion in 2016
