The pith

Network slicing management functions coordinate creation and orchestration for closed, open, and mixed micro-operator deployments.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper sets out a descriptive technique that applies 3GPP-defined network slicing management functions to local 5G micro-operator networks serving multiple vertical sectors. It shows how the network slice instance configuration type can align those functions to create, orchestrate, and manage slices across closed, open, and mixed customer-group scenarios. The technique is illustrated with a formation sequence that assigns specific tasks to the management functions in the closed case. A sympathetic reader would care because the approach lets one local deployment support many tenants with different requirements instead of building separate networks for each vertical. The results claim this coordination is essential for making micro-operator networks economically practical.

Core claim

The paper proposes a descriptive technique by which different network slicing management functionalities defined by 3GPP can be used in coordination to create, orchestrate and manage network slicing for different deployment scenarios of a micro-operator. This is based on the network slice instance configuration type that can exist for each scenario. A network slice formation sequence is developed for the closed micro operator network to illustrate the tasks of the management functions.

What carries the argument

Network slice instance configuration type, which selects and coordinates the 3GPP management functions for each deployment scenario.

If this is right

  • One local micro-operator network can serve multiple verticals and tenants with differing requirements.
  • Management functions are coordinated differently according to whether customer groups are closed, open, or mixed.
  • The formation sequence assigns concrete tasks to each management function in the closed scenario.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • The same coordination pattern might lower the cost of serving industrial or campus verticals that currently require dedicated infrastructure.
  • If the configuration types suffice, micro-operator deployments could proceed without waiting for further 3GPP releases.
  • Field trials that run the formation sequence in mixed scenarios would test whether the coordination works end-to-end.

Load-bearing premise

The network slice instance configuration type defined by 3GPP can be applied directly to coordinate management functions across closed, open, and mixed micro-operator scenarios without extra standardization or changes.

What would settle it

A concrete case in which the 3GPP configuration types cannot produce working slice instances for a mixed micro-operator deployment without new specifications or modifications would falsify the technique.

read the original abstract

Local 5G networks are expected to emerge to serve different vertical sectors specific requirements. These networks can be deployed by traditional mobile network operators or entrant local operators. With a large number of verticals with different service requirements, while considering the network deployment cost in a single local area, it will not be economically feasible to deploy separate networks for each vertical. Thus, locally deployed 5G networks (aka micro operator networks) that can serve multiple verticals with multiple tenants in a location have gained increasing attention. Network slicing will enable a 5G micro-operator network to efficiently serve the multiple verticals and their tenants with different network requirements. This paper addresses how network slicing management functions can be used to implement, orchestrate and manage network slicing in different deployments of a local 5G micro-operator including the serving of closed, open and mixed customer groups. The paper proposes a descriptive technique by which different network slicing management functionalities defined by 3GPP can be used in coordination to create, orchestrate and manage network slicing for different deployment scenarios of a micro-operator. This is based on the network slice instance configuration type that can exist for each scenario. A network slice formation sequence is developed for the closed micro operator network to illustrate the tasks of the management functions. The results indicate that network slicing management plays a key role in designing local 5G networks that can serve different customer groups in the verticals.

Referee Report

2 major / 2 minor

Summary. The paper proposes a descriptive technique for coordinating 3GPP-defined network slicing management functions (via network slice instance configuration types) to create, orchestrate, and manage slices in local 5G micro-operator deployments serving closed, open, and mixed customer groups. It develops an explicit formation sequence only for the closed case to illustrate management tasks and concludes that such management is key to enabling multi-vertical local 5G networks.

Significance. If the coordination technique can be shown to apply without modification across deployment modes, the work would offer a standards-grounded framework for cost-effective multi-tenant local 5G infrastructure. The explicit grounding in 3GPP slice configuration types is a positive feature, but the absence of any validation, implementation details, or cross-scenario demonstration limits the result to a high-level proposal whose practical utility remains untested.

major comments (2)
  1. [Abstract and the section describing the network slice formation sequence] The central claim requires that 3GPP network slice instance configuration types enable coordination across closed, open, and mixed micro-operator scenarios without additional standardization. However, the manuscript develops the formation sequence and management function tasks only for the closed case (as stated in the abstract); applicability to open and mixed cases is asserted from the existence of the corresponding config types but is not demonstrated via sequence, mapping, or example.
  2. [Abstract and conclusion] No empirical validation, simulation, or implementation detail is provided to confirm that the described coordination of management functions actually succeeds in the stated scenarios. The soundness assessment therefore rests entirely on the unexamined assumption that direct application of 3GPP types suffices.
minor comments (2)
  1. [Abstract] The abstract refers to 'the results' and 'the results indicate,' yet the work is purely descriptive with no quantitative or empirical results; this phrasing should be revised for accuracy.
  2. [Introduction and technique description] Specific 3GPP document references (e.g., TS 28.530 or equivalent for slice instance configuration types) are not cited when the config types are introduced; adding these would improve traceability.

  1. Referee: [Abstract and the section describing the network slice formation sequence] The central claim requires that 3GPP network slice instance configuration types enable coordination across closed, open, and mixed micro-operator scenarios without additional standardization. However, the manuscript develops the formation sequence and management function tasks only for the closed case (as stated in the abstract); applicability to open and mixed cases is asserted from the existence of the corresponding config types but is not demonstrated via sequence, mapping, or example.

    Authors: The detailed formation sequence is provided only for the closed case as an explicit illustration of management tasks using the configuration types. Applicability to open and mixed cases follows from the 3GPP definitions of the corresponding configuration types, which specify the same management functions (NSMF, NSSMF, etc.) without requiring new standardization. We agree that explicit mappings would strengthen clarity and will add high-level mappings for open and mixed cases in the revision. revision: partial

  2. Referee: [Abstract and conclusion] No empirical validation, simulation, or implementation detail is provided to confirm that the described coordination of management functions actually succeeds in the stated scenarios. The soundness assessment therefore rests entirely on the unexamined assumption that direct application of 3GPP types suffices.

    Authors: The paper is a conceptual proposal grounded directly in 3GPP specifications for network slice management. Its contribution is the coordination technique via configuration types; empirical validation or simulation lies outside the stated scope and would constitute separate implementation work. Soundness derives from the standards themselves defining these configuration types and functions for the scenarios. revision: no

Circularity Check

0 steps flagged

No circularity: purely descriptive mapping to external 3GPP standards with no derivations or self-referential predictions

full rationale

The manuscript is a descriptive proposal that maps 3GPP-defined network slice instance configuration types and management functions to closed/open/mixed micro-operator scenarios. It develops an explicit formation sequence only for the closed case and states that the same 3GPP types apply to the other cases by virtue of their existence in the standard. There are no equations, fitted parameters, predictions, or internal derivations that reduce to the paper's own inputs. All load-bearing content references external 3GPP specifications rather than self-citations or ansatzes introduced by the authors. The cross-scenario applicability claim rests on an unshown mapping assumption, but this is a limitation of demonstration, not a circular reduction. The work is therefore self-contained against external benchmarks and receives score 0.
