Base Station Dynamic Timeout Configuration for LTE Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RRC protocol in LTE communication technology sets a fixed inactivity timer for all terminals, leading to inefficient resource usage and increased signaling overhead due to varying traffic patterns, resulting in potential call drops and increased battery consumption.
Innovation Solution
A base station method that extracts and configures timeout values for individual terminals based on their specific traffic patterns, releasing connections when the timeout expires without traffic, thereby optimizing resource allocation and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed inactivity timer is set for all terminals, then the connection management is simple, but resource usage becomes inefficient and signaling overhead increases
Solution Approach 1:
The patent applies dynamics by transitioning from a static fixed timer to a dynamic adaptive timer that adjusts based on terminal traffic patterns. The base station monitors terminal traffic characteristics and configures appropriate timeout values individually, allowing the system to adapt to varying usage patterns and optimize resource allocation while maintaining manageable complexity through automated adaptation.
Solution Approach 2:
The patent changes the parameter of timeout value from a fixed constant to a variable parameter that is configured based on terminal traffic patterns. By monitoring actual terminal behavior and adjusting timeout values accordingly, the system optimizes resource usage efficiency without significantly increasing management complexity, as the parameter adjustment is automated based on observed traffic characteristics.
2Reliability
If terminals remain in RRC_CONNECTED state for extended periods, then connection stability is improved, but resource occupation increases causing call drops
Solution Approach 1:
The patent implements feedback by having the base station monitor terminal traffic patterns and use this information to dynamically adjust timeout values. This feedback mechanism allows the system to maintain connections during active usage periods while automatically releasing resources when terminals become inactive, thus preventing resource exhaustion and call drops while ensuring connection stability during necessary communication periods.
3Productivity
If connections are released frequently, then resource efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent optimizes the timeout parameter based on individual terminal traffic patterns to achieve the right balance between connection retention and resource release. By configuring appropriate timeout values for each terminal, the system minimizes unnecessary connection releases and associated signaling overhead while still achieving improved resource efficiency through targeted connection management based on actual usage behavior.
