Mobile Terminal Network Search Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with dual network capabilities, such as UIM cards, experience prolonged network search times due to sequential reading of network parameters for different communication networks like CDMA and GSM, degrading user experience.
Innovation Solution
Implement a method where a mobile terminal searches and reads network parameters sequentially, switching to the second network only if the first is not found or mismatched, allowing for immediate registration with the appropriate network upon successful parameter matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal reads network parameters sequentially for multiple communication networks, then the network parameter reading process is simple and reliable, but the network search time becomes long
Solution Approach 1:
The patent applies preliminary action by pre-organizing network parameters into different sets (first network parameters and second network parameters) corresponding to different communication networks. When the terminal powers on, it can immediately use the appropriate parameter set for the target network without sequential reading, as the parameters are prepared in advance for quick access.
Solution Approach 2:
The patent segments the network parameters into distinct sets (first network parameters for one communication network type, second network parameters for another communication network type). This segmentation allows the terminal to read only the relevant parameter set for the current network search, rather than reading all parameters sequentially, thus reducing network search time while maintaining reliability.
2Loss of time
If the mobile terminal searches for multiple communication networks simultaneously, then the network search time is reduced, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic network search mechanism that can adaptively switch between different network types and parameter sets based on the terminal's current state and configuration. The system dynamically selects which network to search first and which parameter set to use, providing flexibility without requiring complex simultaneous multi-network search capabilities.

AI summary
A communication method comprises: starting, at time T1, searching for a first communication network and reading a first network parameter; terminating, at time T2, the searching for the first communication network; determining, when the first communication network has been found, whether the reading of the first network parameter has been completed, when completed, matching the first network parameter with the first communication network, and registering with the first communication network; when the first communication network has not been found or when the first network parameter does not match the first communication network, stopping the reading of the first network parameter and starting reading the second network parameter when the type of network corresponding to the network parameter is inconsistent with the first network parameter and after reading, searching for the second communication network based on the second network parameter and registering with the found second communication network.
