Description:

Background

Because current cellular networks rely on closed and inflexible infrastructure tightly controlled by a handful of vendors, configuration requires this vendor support and manual operations. The full potential performance of the network remains locked from fine grained performance optimization, especially on a per-user basis. This invention offers a framework for cellular networks that requires negligible intervention (‘zero touch’), hiding low-level network details through a general virtual network abstraction and allows telco operators to define high-level control objectives to dictate the desired network behavior, enabling the future of self-optimized future 5G networks and CellOS.

Technology Overview

CellOS, a fully automated optimization and management framework for cellular networks, requires negligible intervention (“zero-touch”). CellOS leverages softwarization and automatic optimization principles to bridge Software-Defined Networking (SDN) and cross-layer optimization. Unlike state-of-the-art SDN-inspired solutions for cellular networking, CellOS: (i) Hides low-level network details through a general virtual network abstraction; (ii) allows TOs to define high-level control objectives to dictate the desired network behavior without requiring knowledge of optimization techniques, and (iii) automatically generates and executes distributed control programs for simultaneous optimization of heterogeneous control objectives on multiple network slices.

CellOS has been implemented and evaluated on an indoor testbed with two different LTE-compliant implementations: OpenAirInterface and srsLTE.

Benefits

  • Hides low-level network details through a virtual network abstraction so telco operators easily define centralized and high-level control objectives
  • The CellOS is independent of the underlying network and can be adapted to current and future cellular networks

Applications

  • The technology has the potential to be implemented in next-generation cellular networks to simplify network management and improve performance in general
  • Telco operators can guarantee QOS while reducing the labor required to manage
