5G Access Control Signaling Beyond RMSI Capacity Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing access control criteria due to the limited capacity of remaining minimum system information (RMSI) to accommodate the large number of access control parameters required for 5G networks, leading to inefficient use of public control resources and unnecessary energy consumption at terminals.
Innovation Solution
Implementing methods to indicate access control criteria through non-RMSI system broadcast messages, such as OSI and RRC dedicated signaling, allowing terminals to selectively acquire access control information based on availability, manner, and conditions, thereby reducing the need to read all parameters.

Engineering Contradiction Analysis
1Reliability
If access control criteria are configured in RMSI for 5G networks, then access control functionality is provided, but the limited capacity of RMSI cannot accommodate the large number of access control parameters required
Solution Approach 1:
The patent segments access control information into two parts: access criterion indicators ( transmitted in RMSI) and detailed access control parameters (transmitted in other system information). This segmentation allows RMSI to remain within its capacity limits while still providing comprehensive access control functionality through the combination of both parts.
Solution Approach 2:
The patent introduces access criterion indicators as an intermediary element that bridges RMSI and detailed access control parameters. The indicators serve as references that point to the actual parameter values located in other system information, enabling indirect access control configuration without exceeding RMSI capacity.
2Loss of information
If all access control parameters are transmitted in RMSI, then complete access control information is available, but public control resources are inefficiently used and terminal energy consumption increases
Solution Approach 1:
The patent extracts detailed access control parameters from RMSI and places them in other system information, keeping only the essential access criterion indicators in RMSI. This extraction reduces the information burden on RMSI and allows terminals to selectively acquire only the parameter sets relevant to their access categories, thereby reducing energy consumption.
Solution Approach 2:
The patent implements partial action by having terminals read only the access criterion indicators in RMSI and then selectively acquire detailed parameters only when needed and only for their specific access categories. This partial reading approach reduces unnecessary energy consumption while ensuring complete information availability when required.
