Service Management and Automation in 5G
With the disaggregation of a closed construct, value begins to emerge. Examples of disaggregation abound, but white boxes, 5G Core Service-Based Architecture (SBA) and Open Radio-Access Network (RAN) are notable cases. Value chain disaggregation introduces inherent complexities and operational challenges. For example, in Open RAN environments, orchestration and automation of disaggregated radio access is a cumbersome task. Lifecycle management of Distributed Units (DUs) and Centralized Units (CUs) is not an easy endeavor as Open RAN adds more interfaces, network functions, and software components. Though there is more flexibility provided, there is an element of risk that Communications Service Providers (CSPs) need to understand. With ecosystem disaggregation and best of breed deployments, operational costs are expected to explode. Ericsson’s claim, for example, that a lack of automation can potentially increase network operations cost by 100–130% further drives that point home.
When looking at disaggregated value chain there are typically two approaches to avoid…
