6. Newer Opportunities for LTE/WiMAX and IMS
LTE/WiMAX will require regulatory features such as Legal Intercept and Emergency Services for multimedia in both the wireless and wireline space, along with Mobile IP solutions (Foreign Agent and Home Agent)
LTE/WiMAX will require carrier hosted solutions that promise future convergence with VoIP, IPTV, with Presence and Location-based services, which IMS: IP Multimedia Subsystems coupled with applications servers can provide.
Additionally LTE/WiMAX will require the following which are provided by applications servers:
ENUM
User authentication
Peer-to-peer video sharing
Voice call continuity to alternate access methods
Push to talk
Rich Communication Suite

7. Panel Questions
What are the architecture and infrastructure choices for incumbent and greenfield mobile operators for voice services?
Where should service providers locate session-oriented service delivery intelligence and control—in the core or the edge? What’s right and wrong about each approach?
What are the requirements for secure and interoperable wireless services? Does IMS deliver all that's necessary? What additional issues must be considered for FMC and blended wireless-wireline access networks?
What are the optimal technology choices relative to product availability, cost, functionality and scalability in terms of performance and capacity?
