How SDN and NFV extend the adoption and capabilities of self-organizing networks (SON)

Thursday 8 June 2017 | 11:30 CET | White paper | provided by Comarch

Communication service providers (CSPs) are going through rough times trying to reinvent themselves in an age when the network is becoming a commodity. Even though they continue investing in network expansion and quality, network usage is growing rapidly. Therefore, telecom operators are constantly focused on optimizing the utilization of resources in their networks, in order to do more with less.

SON in the radio access network

SON (self-organizing network) is a set of technologies and concepts that help CSPs to reach that goal by automating network operations. Until recently, SON solutions focused solely on the radio access network (RAN). However, the challenge of network optimization relates not only to access, but also to the backhaul and core networks.

Applying the SON concept to other network domains brings its own set of problems. Compared to the RAN, these domains are very heterogeneous in terms of technologies that support them. Network function virtualization and software-defined networking, originally focused on data center networks, have recently been gaining ground in the core and backhaul fields, becoming enablers for the expansion of SON solutions to those network domains.

Currently the use of self-organizing network solutions is limited to the automation or assisted management of the radio access network. The first SON solutions were provided by manufacturers of RAN network equipment to help their customers’ network engineers with network operations. They only worked for equipment provided by one vendor, were usually limited to one or two technologies, and implemented a set of basic use cases. 

Gradually, RAN vendors provided more configurability, interfaces and software for their products, thus enabling more advanced use cases. This finally opened the door for third-party solution providers to develop SON products that supported a range of vendors and technologies.
