6. Seamless connectivity
One provider over multiple networks
Very efficient for billing, technical coordination
Raises antitrust concerns
Partnerships among different networks
May simply create two ubiquitous networks
Billing negotiated among partnerships
Users subscribe to each network separately but use one common ID on the network
Allows the highest degree of consumer choice
Very difficult to coordinate interconnection and network passoffs

7. Network paradigm shift
Current
Future
In a converged network, services will no longer be tied to a one type of network. Instead, the converged network will deliver all services.
