What is a Session Border Controller (SBC)?

SBC (Session Border Controller) NFV (Network Functions Virtualization) IMS (IP Multimedia Subsystem) VoLTE Mobile Infrastructure

A Session Border Controller (SBC) is a network function which secures voice over IP (VoIP) infrastructures while providing interworking between incompatible signaling messages and media flows (sessions) from end devices or application servers. SBCs are employed in Enterprise infrastructures or any carrier network delivering commercial residential, business, fixed-line or mobile VoIP services. They are typically deployed at both the network edge and at carrier interconnects, the demarcation points (borders) between their users and other service providers.

What is Voice over Wi-Fi (VoWiFi)?

IMS (IP Multimedia Subsystem) VoLTE Mobile Infrastructure Voice over Wi-Fi (VoWiFi) Rhino TAS

Voice over Wi-Fi (VoWiFi) is a term typically employed to describe the delivery of commercial telephony services using Voice over IP (VoIP) technologies from mobile devices connected across Wi-Fi. This is typically counter to alternatives, predominantly Voice over LTE (VoLTE), in which a mobile network operator’s (MNO’s) licensed spectrum (i.e. 4G LTE) is used to carry packetized voice. Broadly speaking, VoWiFi terminology is assigned to all core IMS services accessed from unlicensed spectrum and across untrusted access infrastructures, such as public Wi-Fi access points. VoWiFi is used synonymously to describe the GSMAs permanent reference document IR.51: IMS Profile for Voice, Video and SMS over untrusted Wi-Fi access.

What is Voice over LTE (VoLTE)?

IMS (IP Multimedia Subsystem) VoLTE Mobile Infrastructure Rhino TAS

Outlined in GSMA standards, Voice over Long Term Evolution (Voice over LTE or VoLTE) is the practice of packetizing voice over the Internet Protocol (VoIP) and transporting both the signaling and media components over a 4G LTE packet switched (PS) data path. This is in contrast to delivering voice using circuit switch (CS) methodologies, which requires 4G handsets to employ a secondary 3G radio and network operators to continue supporting this inefficient access infrastructure and licensed spectrum.

Simplified VoLTE Roaming - From Dream to Reality

Voice over LTE (VoLTE) is one of the most significant evolutions to have hit the voice world in many years, finally migrating one of the last bastions of traditional circuit switched calling to an IP based service. The migration is not without its issues however, requiring the deployment of a potentially complex infrastructure in the mobile network (known as IP Multimedia System or IMS) together with the skills enhancements required among the technical staff in those networks.

This joint white paper from BT and Metaswitch looks at some of the technical reasons for the delays in deploying VoLTE roaming, and addresses some core issues about complexity and how this can be simplified to smooth the path to full global VoLTE deployment and interconnectivity.

Top 5 Challenges in Modernizing Unified Communications and Collaboration

White papers UC (Unified Communications) Business communications Collaboration Accession Meeting

The business meeting is not what it used to be. The scene of a group of company executives sitting around a table in a conference room while munching on sandwiches and brainstorming ideas is more like a take from Mad Men than a description of how businesses operate today. Even if you update the scene and fill the office with advanced technology such as color- display phones, telepresence or high-end video conferencing systems, it’s still clear that there’s something wrong with this picture.
