Benefits of Self-Organizing Networks (SON)‎ for Mobile Operators

الملخص EN

Self-Organizing Networks (SON) is a collection of functions for automatic configuration, optimization, diagnostisation and healing of cellular networks.

It is considered to be a necessity in future mobile networks and operations due to the increased cost pressure.

The main drivers are essentially to reduce CAPEX and OPEX, which would otherwise increase dramatically due to increased number of network parameters that has to be monitored and set, the rapidly increasing numbers of base stations in the network and parallel operation of 2G, 3G and Evolved Packet Core (EPC) infrastructures.

This paper presents evaluations on the use of some of the most important SON components.

Mobile networks are getting more complex to configure, optimize and maintain.

Many SON functions will give cost savings and performance benefits from the very beginning of a network deployment and these should be prioritized now.

But even if many functions are already available and can give large benefits, the field is still in its infancy and more advanced functions are either not yet implemented or have immature implementations.

It is therefore necessary to have a strategy for how and when different SON functions should be introduced in mobile networks.
