Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently indicating slice-related information, leading to increased air interface signaling overhead and suboptimal support for vertical market requirements on delay, mobility, reliability, and location accuracy.
Innovation Solution
A method for indicating slice information through first slice identification or frequency point information, utilizing various signaling methods such as SIB, dedicated RRC messages, and NAS messages, with optional segmentation and indication mechanisms to manage signaling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slice information is indicated using traditional signaling methods, then complete slice information can be transmitted, but air interface signaling overhead increases
Solution Approach 1:
The patent segments slice information into multiple parts and transmits them through different signaling stages: some slice information is indicated through SIB (System Information Block) while additional slice information is transmitted through dedicated RRC signaling. This segmentation allows the system to balance between providing complete slice information and controlling signaling overhead, as each segment can be optimized independently for its specific transmission context.
2Adaptability or versatility
If detailed slice information is transmitted to support vertical market applications, then service requirements can be met, but latency increases due to processing overhead
Solution Approach 1:
The patent performs preliminary indication of slice information through SIB before establishing dedicated connections. This preliminary action allows terminal devices to pre-process and prepare for vertical market services earlier in the connection establishment process, reducing the time required for subsequent detailed service setup and thereby lowering overall latency while still supporting detailed slice requirements.
3Adaptability or versatility
If comprehensive slice information is provided for all services, then service flexibility is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by providing different levels of slice information detail to different terminal devices based on their specific needs and capabilities. Not all devices receive the same comprehensive slice information - instead, each device receives appropriately tailored slice information relevant to its service requirements, reducing processing complexity while maintaining service flexibility for devices that need it.
