C-RAN

Centralized Radio Access Network = C-RAN

What is C-RAN?  The acronym C-RAN, for “Centralized RAN” is sometimes mistakenly defined as “Cloud-RAN,” but it actually refers to a centralized, cloud-computing-based architecture for radio access networks that supports 2G, 3G, 4G and future telecommunication standards. It is an architecture which enables radios and antennas to be deployed close to the end user without the expense of a base station onsite. The Base station equipment can be located in a less expensive location and connected to the radios with fiber, allowing network capacity to be allocated dynamically.

CA

Carrier Aggregation = CA

What is CA? Carrier aggregation is a feature of LTE-Advanced used to increase the bandwidth and thereby increase the bitrate.

capex

Capital Expenditure = capex

What is capex? The money a company spends to buy, maintain or improve its fixed assets, such as buildings and equipment. This word is commonly capitalized like an acronym, but it is now a word in its own right. Download our White Paper on how with a Cloud RAN Deployment, Mobile Operators Can See 49% Savings in capex and 31% Annual Savings in opex.

Chatbot

What is a Chatbot?  A chatbot (also known as a talkbot, chatterbot, Bot, IM bot, interactive agent, or Artificial Conversational Entity) is a computer program or an artificial intelligence which conducts a conversation via auditory or textual methods. Such programs are often designed to convincingly simulate how a human would behave as a conversational partner, thereby passing the Turing test. The design of Mavenir RCS opens up possibilities to provide advanced communication between third party businesses and messaging users for a wide range of services such as Chatbots, Plugins, Artificial Intelligence and other third party industrial applications. For more information see our Messaging as a Platform services.

Cloud Network Function

What is Cloud Network Function?  Cloud Network Function is defined as a virtual network function (VNF), as described above, but with the added functionality of a VNF Manager and/or orchestration (MANO) that enable automated, elastic demand and service chaining functionality.

Cloud Radio Access Network

Cloud RAN = Cloud Radio Access Network

What is Cloud RAN? Cloud RAN is sometimes referred to vRAN. It is a broader understanding of the C-RAN, which does not limit the RAN to having a centralized architecture. The Cloud RAN in this usage can also imply a MEC architecture, which pushes processing power out to the Access portion of the network, and even further out to the devices themselves.

COTS

Commercial Off the Shelf = COTS

What is COTS? Refers to low-cost servers that are commonly available, plug-and-play appliances for running any virtualized software. Commonly used in Mavenir's 4G and 5G Solutions.

CUPS

Control and User Plane Separation = CUPS

What is CUPS? Essential to 5G networks, CUPS reduces latency on application service, e.g. by selecting User plane nodes which are closer to the RAN or more appropriate for the intended UE usage type without increasing the number of control plane nodes. Also, CUPS supports increase of data traffic, by enabling to add user plane nodes without changing the number of SGW-C, PGW-C and TDF-C in the network. This is independent evolution of the CP and UP functions enabling Software Defined Networking to deliver user plane data more efficiently while maintaining full EPC media service set at the edge.
