v-SAE-GW

Virtual System Architecture Evolution-Gateway = v-SAE-GW

What is v-SAE-GW? This a virtualized gateway function of the vEPC. It is the main component of the Evolved Packet Core (EPC), also known as the SAE Core.

vBBU

Virtualized Base Band Unit = vBBU

What is vBBU? Mavenir Cloud RAN extends functional element virtualization to the edge of the network, and provides strategic differentiation by enabling remote radio units (RRUs) to interwork with the virtualized base band unit (vBBU) over ethernet fronthaul at a tenth of the bandwidth proprietary solutions require. The vBBU is designed to support multiple fronthaul architectures simultaneously and opens the door to previously excluded fronthaul transmission solutions.

vC-SGN

Virtual Cellular IoT Serving Gateway Node = vC-SGN

What is vC-SGN? This is a collapsed packet core designed for virtualized environments to support Cellular IoT (CIoT) traffic. Mavenir vCSGN features simple deployment and optimization with reduced backhaul costs, enabling operators to quickly react to market changes, thus ensuring a high return on investment and a lower total cost of ownership.

vEPC

Virtual Evolved Packet Core = vEPC

What is vEPC? A virtualized evolved packet core (see EPC) moves the core network's individual components that traditionally run on dedicated hardware to software that operates on low-cost commercial off-the-shelf (COTS) servers. vEPC is an innovative Evolved Packet Core (EPC) specifically designed from the ground up for virtualized environments.

VNF

Virtualized Network Function = VNF

What is VNF? Network able to simulate hardware functionality in software as a virtual instance, which is supported on generic host hardware. Mavenir's approach includes architecting VNFs as Microservices, deconstructed into independently scalable components, as well as, an NFV MANO suite. Mavenir NFV CloudRangeputs CSPs in control of VNF or container lifecycle management.

vPGW

Virtualized Packet Data Network Gateway = vPGW

What is vPGW? This a virtualized gateway function of the vEPC. It provides connectivity from the UE to external packet data networks by being the point of entry.

vRAN

Virtual Radio Access Network = vRAN

What is vRAN? A virtual RAN consists of a centralized pool of baseband units (BBUs), virtualized RAN control functions and service delivery optimization. With a virtual RAN, baseband modules are shifted away from the base station and to data centers – resulting in functions of the BBUs to be implemented with virtual machines in a centralized data center. This provides intelligent scaling of computing resources, while decreasing energy consumption and capital expenditure (capex). Mavenir’s innovative vRAN solution (RRU and vBBU) is designed to address the requirements of pre-5G networks with design and programming capabilities that enable simple and inexpensive upgrades to 5G (NR) – providing investment protection and deployment flexibility.
