Mobile Communication Network Search Information Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices with multiple SIM cards face inefficiencies in network search times due to redundant scanning and mode switching between different communication systems, particularly when operating on different network modes such as GSM, UMTS, and LTE.
Innovation Solution
Implementing a network search information sharing channel between communication systems to share carrier frequency and PLMN identity information, allowing one system to skip redundant scans and mode switching, thereby reducing network search time by utilizing the results from the first system's search.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each communication system conducts independent network search, then each system can find available networks reliably, but network search time increases due to redundant scanning
Solution Approach 1:
The patent merges the network search operations of multiple communication systems by allowing them to share search results. When one system performs a network search, the results (including carrier frequencies, cell identities, and network information) are made available to other systems, eliminating redundant scanning while maintaining reliable network discovery for each system.
Solution Approach 2:
The patent applies preliminary action by having the first communication system perform the network search in advance, and then reusing these results by the second communication system. This preliminary search eliminates the need for the second system to repeat the search process, significantly reducing overall network search time while ensuring reliable network information is available.
2Adaptability or versatility
If communication systems operate independently without information sharing, then each system maintains full autonomy, but device complexity increases due to separate search operations
Solution Approach 1:
The patent implements universality by creating a shared network search result database that serves multiple communication systems simultaneously. This multi-functional approach allows different systems to access common network information, reducing the need for separate search mechanisms and lowering overall device complexity while preserving each system's operational autonomy.

AI summary
Aspects of the disclosure provide a method for use in a mobile communication device having at least a first communication system and a second communication system. The method includes conducting a network search with the first communication system to obtain network search information and providing the network search information to the second communication system in the mobile communication device to reduce a network search time of the second communication system.
