Cellular Network Node WCM Segmentation for Bandwidth Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data transmission rates are reduced due to limited bandwidth when multiple SIM cards in a network node connect to the same base station through the same frequency band.
Innovation Solution
The network node employs a plurality of wireless communication modules (WCMs) with rotatable and tiltable antenna elements, allowing for selective connection and disconnection from base stations based on geographical location and antenna orientation to optimize frequency band usage.
Engineering Contradictions & Design Principles
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, but the data transmission rate is reduced due to limited bandwidth
Solution Approach 1:
The patent segments the WCMs into different groups and assigns them to connect to different base stations. Specifically, it identifies a first base station connected to a second plurality of WCMs, selects one WCM to maintain connection with the first base station, and disconnects the remaining WCMs from the first base station to connect them to other base stations. This segmentation distributes the connection load across multiple base stations, preventing bandwidth bottlenecks while maintaining connection reliability.
2Productivity
If multiple WCMs are disconnected and reconnected to different base stations, then bandwidth utilization is improved, but the device complexity increases due to antenna orientation control
Solution Approach 1:
The patent employs rotatable and tiltable antenna elements that can dynamically adjust their orientation. The antenna elements are configured to point in different directions to establish connections with different base stations. This dynamic adjustment capability allows the system to adapt to changing network conditions and optimize bandwidth utilization by connecting WCMs to the most appropriate base stations based on signal strength and available capacity.
Solution Approach 2:
The patent introduces a database as an intermediary component that stores characteristics of antenna elements, current geographical coordination information, WCM group policy information, and frequency band blacklist table information. This database mediates the complex decision-making process by providing structured data and rules that guide the selection and orientation of antenna elements, thereby managing device complexity through organized information storage and retrieval.

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 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.
