Dynamic Network Search Parameter Adjustment for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communications networks with both femtocells and macrocells, mobile terminals face inefficiencies in searching for their home network due to fixed search frequency parameters, leading to battery drain and potential 'ping-pong' effects between networks, especially when roaming between different operator networks.
Innovation Solution
The method involves dynamically adjusting the network search parameter, MinimumPeriodicSearchTimer, based on factors such as time connected to a macrocell, number of recent network switches, location, battery life, and user preferences, allowing the network operator to balance search frequency with battery conservation and quick network reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the network search frequency is increased to enable quicker reconnection to the home network, then the reconnection speed is improved, but the battery consumption increases
Solution Approach 1:
The patent applies dynamics by making the network search parameter variable rather than fixed. The MinimumPeriodicSearchTimer is dynamically adjusted based on multiple factors including time connected to visited network, number of recent network switches, location, battery life, and user preferences. This allows the system to optimize the balance between reconnection speed and battery consumption adaptively.
Solution Approach 2:
The patent implements parameter changes by modifying the MinimumPeriodicSearchTimer value based on different conditions. The network search parameter is changed from a static value to a dynamic one that adapts to network conditions, device state, and user preferences, thereby resolving the contradiction between fast reconnection and battery conservation.
2Stability of the object's composition
If the network search frequency is increased to reduce ping-pong effects between networks, then the network stability is improved, but the battery consumption increases
Solution Approach 1:
The system dynamically adjusts the search frequency based on the number of recent network switches. When ping-pong effects are detected (frequent switching between networks), the parameter is modified to stabilize the connection, reducing unnecessary searches while maintaining network stability.
Solution Approach 2:
The patent incorporates feedback mechanisms by monitoring network switching behavior and using this information to adjust the MinimumPeriodicSearchTimer. The system learns from past network switching patterns and adapts the search frequency accordingly, preventing ping-pong effects while conserving battery energy.
3Ease of operation
If a fixed network search parameter is used, then the device operation is simplified, but the adaptability to different network conditions and user preferences is reduced
Solution Approach 1:
The patent achieves universality by creating a multi-functional parameter adjustment system. The MinimumPeriodicSearchTimer serves multiple purposes: it adapts to different network conditions (femtocell/macrocell environments), responds to device state (battery level, connection duration), and respects user preferences. This single parameter handles diverse scenarios without complicating user operation.
