Uplink Access Control via Allowed Timer for Wireless Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control mechanisms for data transmission in idle and inactive states in wireless communication systems do not effectively manage data transmission timing and congestion, leading to inefficiencies and potential congestion issues.
Innovation Solution
A method where a wireless device receives a timer value based on an access barring check result, allowing or delaying uplink transmissions during configured time intervals, ensuring fair access control for data transmission across connected, idle, and inactive states, and allowing differentiated data transmission based on congestion situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission is allowed in idle state and/or inactive state without access control, then data transmission efficiency is improved, but network congestion increases
Solution Approach 1:
The patent applies preliminary action by performing access barring checks and starting timers before data transmission in idle/inactive states. The network configures barring parameters and timer values in advance, and the wireless device checks access permission before transmitting data, preventing congestion before it occurs rather than reacting to it.
Solution Approach 2:
The patent implements periodic action through access barring checks and timer-based control mechanisms. The network can configure periodic barring parameters, and the device periodically checks access permission and stops transmission when timers expire, creating rhythmic transmission patterns that prevent continuous congestion.
2Object-affected harmful factors
If access control is implemented for data transmission in idle state and/or inactive state, then network congestion is reduced, but access delay increases
Solution Approach 1:
The patent applies partial action by implementing access control only for specific access categories and scenarios where congestion is likely. Not all data transmissions are subject to barring checks - the network can selectively apply control based on traffic type, priority, and congestion conditions, reducing unnecessary delays while still preventing congestion in critical scenarios.
3Ease of operation
If differentiated access control is applied per access category, then fair treatment is achieved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing data transmissions into different access categories with distinct access control parameters. Each category (e.g., emergency, high priority, normal, low priority) has its own barring factors and timer values, allowing the system to manage complexity through structured classification rather than treating all transmissions uniformly.
Data Source
AI summary
A method and apparatus for access control for data transmission in idle mode and/or inactive mode in a wireless communication system is provided. An allowed timer is defined, and the allowed timer is started based on a result of access barring check. While the allowed timer is running, the wireless device can perform an uplink (UL) transmission without further access barring check.
