System Information Grouping for Rapid Cell Access Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular mobile radio communication systems, the existing methods for transmitting system information are inefficient, leading to prolonged time for mobile radio user devices to verify access to a mobile radio cell and establish communication links.
Innovation Solution
The method involves grouping system information into several blocks, with the information required for access verification included in a single block, allowing for rapid transmission and verification, utilizing the data link and network layers, and the physical layer for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If system information is transmitted using existing methods, then complete system information is provided to mobile radio user devices, but the time required for devices to verify access and establish communication links is prolonged
Solution Approach 1:
The patent segments system information into multiple information blocks, with the first information block containing specifically the suitability information needed for access verification. This segmentation allows mobile radio user devices to receive and process only the essential information quickly, without waiting for the complete system information, thereby reducing verification time and improving registration speed.
Solution Approach 2:
The patent extracts the critical suitability information from the complete system information and places it in a separate first information block that can be transmitted and processed independently. This extraction enables devices to verify access rights efficiently without being hindered by the transmission time of the entire system information set.
2Speed
If system information is grouped into multiple blocks with suitability information in a single block, then access verification is accelerated, but the overall system information transmission structure becomes more complex
Solution Approach 1:
The patent divides system information into multiple blocks with a clear hierarchical structure: a first information block for suitability information and subsequent information blocks for other system parameters. This segmentation, while increasing structural complexity, enables parallel processing and selective reception, thereby improving information reception speed.
Solution Approach 2:
The patent applies local quality by assigning different functions to different information blocks - the first information block specifically contains suitability information for access verification, while other blocks contain different system information. This functional differentiation allows devices to process critical information faster without affecting the completeness of the overall system information transmission.
