Vendors That Can Provide SON '2.0' Capabilities Will Unlock MNO Investment and Play a Significant Role in 5G Migrations

Self-optimising network (SON) solutions have been hailed as the route to efficient, flexible mobile networks in which manual processes are automated to support massive scale. In reality, deployments beyond very basic use cases have been limited and our survey indicates that most mobile network operators (MNOs) have reduced their 1-to-2-year investment expectations as they wait for more functionality. Vendors need to kickstart a new wave of investment in SON technology by making it a platform that can improve revenue, not just reduce costs, and become the brains of the new network.

This report provides answers to the following questions:

  •     How can vendors develop SON solutions to enhance their platforms for 4.5G and 5G migration?
  •     How will SON solutions improve the returns from densification and virtualisation?
  •     What is the role of SON solutions in an effective 5G ROI strategy?
  •     How much do MNOs intend to invest in SON solutions between 2016 and 2022 and for what purposes?
  •     What will hold MNOs back from deploying SON solutions?
  •     What do MNOs want vendors and industry organisations to deliver to make their plans viable to deploy?

Who Should Read this Report

  •  CTOs, CIOs and business development executives in vendors providing,  or planning to provide SON and wider network optimisation solutions to MNOs or other operators. These include pure-play SON providers, NEPs, telecoms software providers, telecoms service providers, small-cell and Wi-Fi access point vendors.
  •  MNO CTO departments that want insight into what their peers and competitors are thinking about how they are planning to use SON solutions.

About this report

Executive summary
    SON solutions have not met MNO expectations; without an acceptable SON 2.0, MNOs will struggle to implement 5G
    Operators are looking for two major changes from SON 2.0 – commercial alignment and 5G enablement
    Recommendations
DRIVERS AND INHIBITORS OF SON
    High expectations for SON among operators, but so far commercial progress has been disappointing
    There are real drivers to adopt SON solutions, but the goalposts are moving, and none has yet been urgent enough to spark mass adoption
    Meanwhile, new functions alone will not break down barriers – SON 2.0 vendors must address end-to-end platforms and processes
    MNOs remain wary of automation, but they must be equipped to compete with new rivals that take automation as a starting point
    Vendors need to unlock revenue by convincing MNOs that safe choices will put them at a competitive disadvantage
SON 2.0 ESSENTIAL TO UNLOCK MNO SPENDING
    To make SON essential, vendors must outline a clear SON 2.0 roadmap to improve revenue/cost ratio, enable new services and lead to 5G
    Densification makes SON solutions essential, not nice to have, and from 2016 this will be a key element of MNOs' network evolution
    Efficiency, density, flexibility and integration are the critical success factors for SON 2.0
    SON vendors must also prove a direct link to new revenue enablement and service agility in order to make the business case
    As networks and services become more complex, cloud-SON will be essential to deliver full benefits
HOW VENDORS CAN PUSH SON TO THE TIPPING POINT
    Five pillars of the new SON will help overcome resistance to automation and unlock MNO investment, laying the ground for 5G
    Very high level of innovation is driving SON towards the tipping point, but fragmentation is still a potential barrier to mass deployment
    With interoperability, the market is better placed to take off, for those vendors that can deliver simple deployable systems
    SON vendors need to learn lessons from the open-source community and embrace open models to kickstart deployment will make SON into an open, service-centric platform and vendors will gain advantage if they provide a smooth migration path for customers
