Wireless Access Restriction via Priority Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face network congestion due to the increasing number of devices, leading to inefficient access management, with existing solutions like access class barring being crude and resource-intensive, and current rejection mechanisms only addressing a limited number of devices at a time.
Innovation Solution
Implementing a method to transmit access restriction data via paging or access channels, allowing for flexible prioritization and temporary restriction of access to communication channels, enabling efficient network resource management by preventing excessive access requests from low-priority devices during congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access class barring is used to control device access, then network congestion is reduced, but the mechanism is crude and resource-intensive
Solution Approach 1:
The patent segments wireless communication devices into different access classes based on priority levels (e.g., emergency services, priority subscribers, regular subscribers). This segmentation allows differentiated access control where higher priority classes can access the network during congested conditions while lower priority classes are restricted, providing more refined congestion management than uniform blocking mechanisms.
Solution Approach 2:
The access restriction data includes time interval parameters that dynamically control the duration and timing of access restrictions. The system can implement temporary restrictions for specific periods, allowing dynamic adjustment of network access policies based on congestion conditions and time-sensitive requirements, making the control mechanism more adaptable and less resource-intensive.
2Reliability
If current rejection mechanisms are used to limit device access, then some access control is achieved, but only a limited number of devices can be addressed at a time
Solution Approach 1:
The patent employs paging messages and access messages as universal communication vehicles that can simultaneously address multiple devices across different access classes. These messages broadcast access restriction data to numerous devices at once, enabling the system to control access for large numbers of devices simultaneously rather than handling them individually, thus significantly improving productivity.
3Adaptability or versatility
If more wireless communication devices are added to the network, then service coverage is improved, but network resources decrease and congestion increases
Solution Approach 1:
The patent applies local quality by assigning different access rights and priority levels to different groups of devices based on their characteristics (e.g., emergency services, priority subscribers). This allows the network to provide enhanced service quality to specific local groups while managing overall resource allocation, enabling the network to accommodate more devices without proportionally increasing available resources for all devices uniformly.

AI summary
Devices, systems, articles of manufacture, and methods for restricting access to a communication channel are described. According to some embodiments, a message with access restriction data addressed to at least one wireless communication device is generated. The access restriction data indicates that a group of wireless communication devices is associated with a priority value and that the group of wireless communication devices has restricted access to a communication channel. The message is transmitted to the at least one wireless communication device. Other aspects, embodiments and features are also claimed and described.
