“Network slicing opens new business opportunities for operators by enabling them to provide specialized services that deliver specific performance parameters. Guaranteeing stringent KPIs enables operators to charge premium rates to customers that value such performance. The flip side is that such agreements will inevitably come with tough contractual obligations and penalties when the agreed KPIs are not met…even high numbers of slices could be managed without needing to increase the number of operational staff. The more automation applied, the lower the operating costs. At 100 percent automation, there is virtually no cost increase with the number of slices. Granted this is a long-term goal and impractical in the short to medium term, yet even 50 percent automation will bring very significant benefits.”
From a paper by Nokia – “Unleashing the economic potential of network slicing.”
With typical communications services tending towards commoditisation, operators will naturally seek out premium customers. Customers with premium requirements such as latency, throughput, reliability, mobility, geography, security, analytics, etc.
These custom requirements often come with unique network configuration requirements. This is why network slicing has become an attractive proposition. The white paper quoted above makes an attempt at estimating profitability of network slicing including some sensitivity analyses. It makes for an interesting read.
The diagram below is one of many contained in the White Paper:
It indicates that a significant level of automation is going to be required to achieve an equivalent level of operational cost to a single network. To re-state the quote, “The more automation applied, the lower the operating costs. At 100 percent automation, there is virtually no cost increase with the number of slices. Granted this is a long-term goal and impractical in the short to medium term, yet even 50 percent automation will bring very significant benefits.”
Even 50% operational automation is a significant ambition. OSS hold the key to delivering on this ambition. Such ambitious automation goals means we have to look at massive simplification of operational variant trees. Simplifications that include, but go far beyond OSS, BSS and networks. This implies whole-stack simplification.
