Circuit-Switch Fallback (CSFB) enables circuit-switched voice and SMS services to be delivered to Long Term Evolution (LTE) devices. When an LTE handset makes or receives voice calls, the device "falls back" to the 3G or 2G network to complete the call. This feature is needed because LTE is an all-IP, packet-based network that cannot support circuit-switched calls.
CSFB requires a new interface to be set up between the legacy mobile switching center (MSC) and the mobile management entity (MME) in the LTE core network. It was specified in 3rd Generation Partnership Project (3GPP) Release 8.
CSFB is often described as an interim solution for LTE operators, while Voice over LTE (VoLTE) is considered to be the longer-term goal for delivering voice and other media-rich services on LTE networks.
Light Reading is spending much of this year digging into the details of how automation technology will impact the comms market, but let's take a moment to also look at how automation is set to overturn the current world order by the middle of the century.
Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.
During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.
She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
