Network Slice Access Control via Suspend Time Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications networks, especially during overload situations, there is a need to control user equipment access to user plane radio communication resources to prevent further overload, as existing methods lack efficient mechanisms for managing access across multiple network slices and services.
Innovation Solution
The method introduces a suspend time interval for user equipment to control access to user plane radio communication resources and network slices, using specific suspend time indications and global suspend time information transmitted via control channel data, allowing or disallowing access based on these intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment is allowed to access user plane radio communication resources during overload situations, then network service continuity is maintained, but network overload increases
Solution Approach 1:
The patent implements periodic action by introducing suspend time intervals during which user equipment is temporarily blocked from accessing user plane radio communication resources. This periodic suspension allows the network to recover from overload conditions while maintaining service continuity - equipment can attempt access before the suspend period, during which network resources are protected, and can retry after the suspend period expires.
Solution Approach 2:
The patent applies preliminary anti-action by proactively blocking user equipment access to user plane radio communication resources before the overload situation worsens. The suspend time indication is transmitted in advance to prevent further access attempts that would exacerbate the overload, thereby protecting the network from harmful effects before they fully manifest.
2Stability of the object's composition
If access control is implemented to reduce network overload, then network stability is improved, but user equipment access capability is reduced
Solution Approach 1:
The patent implements dynamics by making the access control mechanism adaptive rather than static. The suspend time interval is not fixed but is dynamically determined based on network conditions, overload severity, and service priorities. This allows the system to balance network stability with user access capability - during severe overload, longer suspend periods protect the network, while during lighter conditions, shorter or no suspend periods maintain good user access.
Solution Approach 2:
The patent applies local quality by differentiating access control treatment across different network slices and services. Instead of uniformly blocking all user equipment, the suspend time indications can be applied selectively to specific network slices or service types, allowing critical services to maintain access while non-critical services are suspended, thereby maintaining overall network stability while preserving essential access capabilities.
3Adaptability or versatility
If multiple network slices are provided for fine-grained service provision, then service flexibility is improved, but control complexity increases
Solution Approach 1:
The patent implements segmentation by dividing the access control mechanism into network slice-specific components. Each network slice can have its own suspend time indication and access control parameters, allowing independent management of different services. This segmentation enables fine-grained control over each slice while maintaining overall system simplicity through modular, standardized control procedures.
Solution Approach 2:
The patent applies universality by designing a standardized suspend time indication mechanism that can be applied across multiple network slices and service types. Rather than implementing separate complex control systems for each slice, a universal suspend time indication framework provides multi-functional control that simplifies management while supporting diverse service requirements through configurable parameters.
