As 5th Generation research reaches the twilight,
the research community must go beyond 5G and look towards
the 2030 connectivity landscape, namely 6G. In this context, this
work takes a step towards the 6G vision by proposing a next
generation communication platform, which aims to extend the
rigid coverage area of fixed deployment networks by
considering virtual mobile small cells (MSC) that are created on
demand. Relying on emerging computing paradigms such as
NFV (Network Function Virtualization) and SDN (Software
Defined Networking), these cells can harness radio and
networking capability locally reducing protocol signaling
latency and overhead. These MSCs constitute an intelligent pool
of networking resources that can collaborate to form a wireless
network of MSCs providing a communication platform for
localized, ubiquitous and reliable connectivity. The technology
enablers for implementing the MSC concept are also addressed
in terms of virtualization, lightweight wireless security, and
energy efficient RF. The benefits of the MSC architecture
towards reliable and efficient cell offloading are demonstrated
as a use-case
