- this is an iterative process, in the initial years, until there is widespread adoption of 5G in the industry. Identify and prioritize near-term Identify and Select target opportunites (segments and use cases) close capability industry and Deploy, replicate, gaps for ecosystem role Customer Local and scale early slicing Use case Business to pursue maturity market developments maturity potential & interest condition Figure 13.5 - A selection of network slices With a phased approach based on prioritization of the industry, segments, and use cases, CSPs can try to overcome the network slicing challenges and reduce their risk exposure. See Figure 13.6 for the suggested phased approach. The investments increase with the phases, but the initial phase helps to get started with network slicing-based services. Phase Description Phase 1 - Basic Network Enable basic slicing capabilities in the CSP's networks Slicing Capabilities Plan for network slicing manager, template management, domain orchestration, and repositories Deploy a few static slices with a basic level of automation or manual configuration for simple use cases Phase 2 - End-to-end Deployment of slicing automation across network domains slicing automation and Deploy end-to-end orchestration, resource, and product and revenue management deployment scaling Scale to be able to deploy several slices within the same physical network Phase 3 - Advanced Enhance CSP capabilities by business and customer enablement slicing business and functions monetization models Focus on partner and channel management, sales and marketing, and establishing a 5G marketplace CSPs to deploy hundreds of dynamic slices with backend system functionalities to enable enhanced slicing use cases Figure 13.6 - A phased approach for network slicing rollout by CSPs As the CSPs mature with the slicing Lifecycle Management (LCM), they will need to ensure they have Network Functions Virtualization Infrastructure (NFVI) and capacity in a physical network. This requirement includes adequate radio cov
