| contents | With 5G's rapid global uptake, demand for agile private networks has exploded. A defining beyond-5G capability is network slicing. 3GPP specifies three core slice categories, massive Machine-Type Communications (mMTC), enhanced Mobile Broadband (eMBB), and Ultra-Reliable Low-Latency Communications (URLLC), while ETSI's Zero-Touch Network and Service Management (ZSM) targets human-less operation. Yet existing documents do not spell out end-to-end (E2E) management spanning multiple domains and subnet instances. We introduce the Network Slice-as-a-Service Platform (NASP), designed to work across 3GPP and non-3GPP networks. NASP (i) translates business-level slice requests into concrete physical instances and inter-domain interfaces, (ii) employs a hierarchical orchestrator that aligns distributed management functions, and (iii) exposes clean south-bound APIs toward domain controllers. A prototype was built by unifying guidance from 3GPP, ETSI, and O-RAN, identifying overlaps and gaps among them. We tested NASP with two exemplary deployments, 3GPP and non-3GPP, over four scenarios: mMTC, URLLC, 3GPP-Shared, and non-3GPP. The Communication Service Management Function handled all requests, underlining the platform's versatility. Measurements show that core-network configuration dominates slice-creation time (68 %), and session setup in the URLLC slice is 93 % faster than in the Shared slice. Cost analysis for orchestrating five versus ten concurrent slices reveals a 112 % delta between edge and centralized deployments. These results demonstrate that NASP delivers flexible, standards-aligned E2E slicing while uncovering opportunities to reduce latency and operational cost. |
