Solution Overview
Problem
Existing communication technologies face challenges in effectively controlling network processing in slice networks, particularly in managing overload and access control across different slices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing technology is introduced to provide differentiated services, then service quality and resource allocation are improved, but access control complexity and processing overhead increase
Solution Approach 1:
The patent segments the access control mechanism by introducing slice-specific access control information for each network slice. Instead of a unified access control approach, the system maintains separate access control parameters (such as access barring status, backoff indicators) for different slices, enabling differentiated service control while managing complexity through structured organization of slice-specific data.
Solution Approach 2:
The patent applies local quality by implementing slice-specific access control characteristics. Each network slice has its own access control information stored in the terminal, allowing individualized control of access rights, backoff behavior, and timing parameters tailored to the specific requirements of each slice, thereby achieving fine-grained service differentiation.
2Measurement precision
If slice-specific access control information is maintained for each slice, then access control precision is improved, but memory consumption and processing overhead increase
Solution Approach 1:
The patent applies partial action by maintaining access control information only for active or relevant network slices rather than all possible slices. The terminal stores slice-specific access control information selectively based on current network conditions and active slices, reducing the quantity of stored information while preserving precise control where needed.
Solution Approach 2:
The patent implements universality through a unified access control information structure that can be applied across different slices. The access control mechanism uses standardized data structures and processing logic that work for all slices, reducing the need for completely separate control systems for each slice and thereby limiting the increase in storage requirements.
3Reliability
If the terminal waits for timer expiration before accessing the network, then network overload is reduced, but access time and user experience deteriorate
Solution Approach 1:
The patent applies dynamics by implementing dynamic access control adjustments based on real-time network conditions and slice-specific parameters. Instead of using fixed wait times, the system dynamically determines access timing based on current overload status, backoff indicators, and slice characteristics, allowing flexible control that balances network reliability with minimizing access delay.
Solution Approach 2:
The patent implements preliminary action through advance warning mechanisms and proactive access control. The terminal receives advance information about network status and slice availability, allowing it to plan access timing in advance and avoid unnecessary delays. Backoff indicators and timer management are performed preliminarily to prepare for optimal access timing.
