This decentralised approach also capitalises on the benefits of NFV/SDN (Network Function Virtualization/Software Defined
Networks), enabling core mobile networks, which used to require large racks of specialized and expensive hardware, to run on
simple, inexpensive commodity hardware. While operational costs are reduced due to avoiding backhaul traffic, deployment
costs are also reduced due to NFV/SDN and the use of commodity hardware running the EPC.
With this model, all the functionality of a core LTE network - the EPC - is implemented in software running on standard Linux
hardware located at, or even integrated, into small cells and base stations. Running the EPC at the cell and interconnecting
the cells to each other using a local mesh network creates a group of autonomous, fully functioning mobile networks. Depending on the use case, these small, yet fully functioning, mobile networks can even be mobile themselves - deployed in a
vehicle, for example.
The beauty of this approach in a remote communications setting is that satellite backhaul need only be used for non-local communications. By keeping local communications local, backhaul traffic volumes can be dramatically reduced and the
considerable latency problems associated with satellite backhaul are mostly eliminated. At the same time, the distributed core
network also greatly improves resilience as the autonomous local networks can continue to provide local communications,
even if the satellite link has dropped.
In practice, this model would involve deploying an EPC such as OpenEPC (CND's core mobile network software) on Linux
hardware, and attaching this to a local LTE base station or small cell, which in turn would be connected to a satellite dish for
backhaul communications. Even further optimization can be achieved by running the EPC on the small cells (using the processor and memory of the small cell), effectively eliminating the need for additional hardware to operate the core network.
In conclusion, with Mobile Edge Computing and a distributed EPC, there is a new option for the mobile industry to transform
their remote communications infrastructure and to offer greatly improved services that provide a competitive edge. This disruptive approach is based on existing standards-based technologies, offers substantial benefits to the end-user, and can radically
reduce deployment and operational costs at the same time.
