The integration of Artificial Intelligence (AI)/Machine Learning (ML) in 5G networks, enables network automation, enhancing the user experience and developing novel industry models that present telecom operators a competitive edge. However, developing compelling business models demands wide use of software skill sets, incorporating virtualization, softwarization, orchestration, and automation.
There are various steps to implement system integration. Let’s have a look at it.

  • Network Planning and Design: The primary step is to determine the requirements of the integrated systems to get the best output. Once, the requirements of the telecom Service Providers (SPs) are identified, it is necessary to create network designs to realize performance optimization. This stage of careful planning and architecture designing indicates the development, setting up, and strategy of telecommunication services. Planning comprises working out the technical specifications, compelling factors, coverage, and implementation blueprint.
  • Hardware and Software Integration: The diverse hardware and software modules needed to be combined to realize unified solutions. System integrators should ensure the compatibility of various systems in the network, such as routers, servers, and more.
  • Configuration and Optimization: The network configurations need to be optimized to ensure proper resource utilization, better capacity, and continuous connectivity.
  • Testing and Troubleshooting: To maintain quality assurance and stability, it becomes important to perform complete testing to detect any potential threats or issues.
  • Security Implementation: To cope with cyber threats, system integrators should implement strong security methods to prevent illegal access.
  • Maintenance: To underpin seamless operations, regular maintenance is crucial. Any threats or errors should be monitored continuously to ensure high-quality service.

Let’s explore what functionalities of system integrators add value to the evolving telecom industry

  • Operational Efficiency: This is achieved by validating that the network functions are operating optimally, realizing enhanced performance, lower downtime, and reduced cost of operation.
  • Scalability and Flexibility: The solutions are designed by system integrators in a way to adapt to the changing customer demands and technological innovations. This introduces flexibility and scalability for telecom operators to scale the networks to provide futuristic services.
