Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data transmission rates are reduced due to limited bandwidth when multiple SIM cards within a network node connect to the same base station through the same frequency band.
Innovation Solution
The network node employs a plurality of WCMs with rotatable and tiltable antenna elements, allowing selective disconnection and reconnection to different base stations based on current geographical area and antenna orientation, utilizing a database for antenna characteristics and geographical information to optimize connections.

Engineering Contradiction Analysis
1Reliability
If multiple WCMs connect to the same base station through the same frequency band, then the network node can maintain multiple connections for redundancy, but the data transmission rate is reduced due to limited bandwidth
Solution Approach 1:
The patent segments the WCMs into different groups, with each group connecting to different base stations through different frequency bands. This segmentation allows the system to maintain connection redundancy while avoiding bandwidth conflicts, as each WCM group operates on separate frequency resources.
Solution Approach 2:
The patent introduces additional dimensions for connection diversity by utilizing multiple frequency bands and multiple base stations simultaneously. Instead of having all WCMs compete for the same frequency band, the system distributes connections across different frequency dimensions and base station dimensions, thereby maintaining redundancy while expanding total available bandwidth.
2Device complexity
If multiple WCMs use the same frequency band, then device complexity is reduced, but bandwidth utilization is limited and data transmission performance deteriorates
Solution Approach 1:
The patent implements dynamic frequency band and base station selection where the system can adaptively assign different frequency bands and base stations to different WCM groups based on current network conditions, geographical location, and traffic demands. This dynamic approach allows the system to optimize bandwidth utilization without significantly increasing device complexity.
Solution Approach 2:
The patent changes key parameters including frequency band allocation, base station selection, and WCM grouping configuration to optimize data transmission performance. By adjusting these parameters dynamically, the system can utilize wider bandwidth resources while maintaining manageable device complexity through automated parameter optimization.

AI summary
Methods and systems for improving connectivity between a network node and a base station during data communication over a cellular network are described. The network node comprises a first plurality of WCMs. The method includes identifying, by the network node, a first base station connected to a second plurality of WCMs. The second plurality of WCMs include all or part of the first plurality of WCMs. After that, a WCM is selected from the second plurality of WCMs to maintain a connection with the first base station. The rest of the second plurality of WCMs are disconnected from the first base station. The disconnected WCMs are reconnected in a manner so that each of the second plurality of WCMs becomes connected to a different base station or to the same base station over different frequency bands.
