On-Demand System Information Acquisition in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current system information acquisition in 5G networks leads to redundant transmission of unnecessary information, causing waste of communication resources due to periodic transmission methods.
Innovation Solution
A method where a terminal requests system information from a base station, with the base station responding with transmission indication information, allowing the terminal to acquire system information based on specific transmission parameters, reducing unnecessary transmissions by targeting only needed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If system information is periodically transmitted by base station, then terminal can acquire system information, but communication resources are wasted due to redundant transmission of unnecessary information
Solution Approach 1:
The terminal autonomously determines what system information it needs and sends requests to the base station. The base station then provides only the requested information, eliminating the need for periodic omnidirectional broadcasting of all system information to all terminals.
Solution Approach 2:
The system transitions from static periodic broadcasting to dynamic on-demand transmission. The transmission timing, content, and target are dynamically adjusted based on actual terminal requests and network conditions, allowing the system to adapt to varying information needs.
2Adaptability or versatility
If system information is transmitted periodically to all terminals, then all terminals can receive system information, but transmission efficiency decreases due to redundant information sent to multiple terminals
Solution Approach 1:
The patent extracts only the necessary system information that specific terminals need from the complete set of system information. Instead of transmitting all system information to all terminals, the base station extracts and transmits only the relevant portions based on terminal requests.
Solution Approach 2:
System information is segmented into different categories or types, and terminals request only the segments they need. This segmentation allows for targeted transmission to different terminals based on their specific requirements, improving overall transmission efficiency.

AI summary
The present application relating to the field of application of communication technologies provides a method, an apparatus and a system for acquiring system information. The method includes: a terminal transmits a system information request to a base station; and the terminal receives a system information request response transmitted by the base station, where the system information request response includes system information or transmission indication information of the system information; where the transmission indication information is used to indicate that the terminal acquires, based on the transmission indication information, the system information transmitted by the base station. In the present application, redundant transmission of unnecessary information can be avoided and waste of communication resources can be reduced. The present application is used for acquiring system information in a mobile communication system.
