This paper identifies these issues and looks for remedies via the new 4G architecture and interfaces. The paper examines the ‘Full’ MVNO model as a ‘Home’ network in a pseudo roaming scenario (National Roaming), allowing MVNO to connect to multiple MNOs through the discovery...
Long Term Evolution (LTE) as an evolution of fourth generation (4G) technology offers high data rate of upto 100 Mbps for data applications. But it lacks native support for Circuit Switched (CS) voice service which has been the main revenue generator for operators. This introduces the problem of how to provide voice call when a user is in LTE and how to ensure voice call continuity when it moves out...
