LTE Voice Through Fallback to 3G,Long Term Solution is VoIP using IMS

LTE focused on data while leveraging 3G for voice 3

1Simultaneous 1X Voice and DO (SVDO) planned across future Qualcomm DO chipsets, simultaneous WCDMA voice and HSPA data available today. HSPA+ will also support ‘CS over HS’ voice.Simultaneous Voice and data also through VoIP over EV-DO. 2Requires VCC for service continuity 3LTE air interface supports VoIP, but initial focus is on data with data optimized devices.
