Dynamic Search Timer for Mobile Network Home Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communications networks face inefficiencies in managing the frequency of searches for a home network when a mobile terminal moves out of femtocell coverage or experiences frequent network switches, leading to battery drain and potential ping-pong effects between networks.
Innovation Solution
The method involves dynamically adjusting the MinimumPeriodicSearchTimer parameter based on various factors such as time since connection to a visited network, number of recent switches, location, battery condition, and user preferences, allowing the network operator to balance search frequency with battery life and network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the mobile terminal frequently searches for the home network to ensure quick discovery, then network switching speed is improved, but battery consumption increases
Solution Approach 1:
The MinimumPeriodicSearchTimer parameter is dynamically adjusted based on multiple factors including time since connection to visited network, number of recent network switches, location information, battery condition, and user preferences. This dynamic adjustment allows the system to optimize the balance between search frequency and battery consumption in real-time
Solution Approach 2:
The invention changes the parameter values of MinimumPeriodicSearchTimer based on different operational conditions. When the terminal has been connected to a visited network for a long time or has frequent switches, the timer is reduced to enable quicker home network discovery. When battery level is low or the terminal is stationary, the timer is increased to conserve energy
2Speed
If the mobile terminal performs frequent network searches, then home network discovery speed is improved, but ping-pong effects between networks worsen
Solution Approach 1:
The system implements periodic network searches controlled by the MinimumPeriodicSearchTimer parameter, which is dynamically adjusted to prevent excessive searching. The periodic action is adapted based on connection duration to visited network, number of recent switches, and location stability to maintain network connection stability while enabling timely home network discovery
Solution Approach 2:
The system uses feedback from multiple sources including connection duration, number of recent network switches, location information, and battery status to adjust the search frequency. This feedback mechanism prevents excessive searching that could cause ping-pong effects while ensuring timely discovery when the home network becomes available
3Productivity
If the network operator implements dynamic parameter adjustment, then network resource utilization is optimized, but system complexity increases
Solution Approach 1:
The network operator's apparatus implements a multi-functional system that collects information from multiple sources (connection duration, location, battery status), processes this information, and dynamically adjusts the MinimumPeriodicSearchTimer parameter. This universal system handles various operational scenarios through a unified approach, optimizing network resource utilization across different conditions
