Service Model Management Request for 5G Network Onboarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile and wireless telecommunication systems, particularly in 5G networks, face challenges in managing end-to-end network services due to the lack of availability of required domain services within management domains, leading to incomplete service onboarding and potential service instantiation failures.
Innovation Solution
A method and apparatus that receive an end-to-end network service model, determine the required domain services, check for their availability, and request management domains to prepare and provide missing services, enabling notification of availability, thus ensuring complete service onboarding and instantiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If domain services are not available in management domains, then service onboarding cannot be completed, but requesting management domains to prepare services increases system complexity and coordination overhead
Solution Approach 1:
The system performs preliminary checking of domain service availability before service onboarding is initiated. By determining whether required domain services are available in advance and requesting management domains to prepare them beforehand, the system avoids mid-process failures and reduces the need for complex retry coordination mechanisms.
Solution Approach 2:
The system implements a feedback mechanism where management domains notify the service management system when required domain services become available. This feedback loop allows the system to automatically detect service availability changes and proceed with onboarding without complex polling or manual intervention, resolving the contradiction between reliability and complexity.
2Reliability
If the system checks for domain service availability before onboarding, then service instantiation failures are prevented, but the onboarding process time increases
Solution Approach 1:
The system performs availability checking as a preliminary step during the onboarding phase, before service instantiation is attempted. By detecting unavailable domain services early in the process, the system can request their preparation in advance and avoid time-consuming instantiation failures, thereby improving success rate while minimizing overall time loss.
Solution Approach 2:
The notification mechanism provides real-time feedback on domain service availability changes. When domain services become available, management domains automatically notify the service management system, which can then immediately proceed with onboarding. This eliminates the need for continuous polling and reduces the time penalty associated with availability checking.
3Reliability
If manual intervention is used to check domain service availability, then service onboarding can be completed, but operational efficiency decreases
Solution Approach 1:
The system implements automated self-service mechanisms where the service management system independently checks domain service availability, interprets results, and requests preparation from management domains without human intervention. Management domains autonomously monitor their service availability and automatically send notifications when services become available, eliminating manual operations while ensuring reliable onboarding completion.
Solution Approach 2:
The automated feedback loop between management domains and the service management system replaces manual checking operations. Management domains continuously monitor service availability and automatically notify the system of changes, enabling the system to maintain high operational efficiency while ensuring reliable detection of service availability for complete onboarding.

AI summary
Systems, methods, apparatuses, and computer program products for a service model management request. The method may include receiving an end-to-end network service model for network services. The method may also includes determining a set of domain services that are required to be able to provide an end-to-end network service defined by the end-to-end network service model. The method may further include checking whether at least one management domain is capable of providing the required set of domain services. The method may also include requesting, when the at least one management domain is not capable of providing the required set of domain services, to prepare the at least one management domain to become able to provide the required set of domain services. In addition, the method may include receiving a notification from the at least one management domain indicating an availability to provide the required set of domain services.
