Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to efficiently support vertical industries with varying service requirements, particularly in terms of latency, mobility, and location accuracy, due to limitations in network slicing configurations.
Innovation Solution
A wireless communication method and device that enable a terminal device to perform cell reselection or connection establishment procedures based on indication information for intended slices, and a network device to determine and manage configurations such as DC, CA, cell handover, or redirection to ensure service transmission for the intended slice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device is configured with a slice and obtains information of an intended slice, then the network can support multiple services with different requirements, but the terminal device lacks clear processing guidance leading to uncertainty in service transmission
Solution Approach 1:
The terminal device autonomously determines whether to perform cell reselection or trigger connection establishment procedure by comparing the intended slice with currently configured slices, without requiring explicit network instruction for each decision scenario
Solution Approach 2:
The network device provides indication information to the terminal device regarding slice configuration status, enabling the terminal to make informed decisions about cell reselection or connection establishment based on network state feedback
2Ease of operation
If the terminal device autonomously handles slice information processing, then processing flexibility is improved, but inconsistent behavior across different terminal devices may occur
Solution Approach 1:
The patent establishes universal processing rules that apply to all terminal devices in slice scenarios, ensuring consistent behavior through standardized procedures for cell reselection and connection establishment triggered by slice information
3Reliability
If the network device manages all slice configuration decisions, then control and reliability are improved, but network complexity and signaling overhead increase
Solution Approach 1:
The patent segments decision-making authority between network device and terminal device: the network provides slice configuration information and indication, while the terminal autonomously determines specific actions (cell reselection or connection establishment), reducing network device complexity
Solution Approach 2:
The network device pre-configures slice information and provides indication information to the terminal device in advance, enabling the terminal to autonomously make decisions without requiring real-time network intervention for each scenario
