Base Station Integrating Broadcast and Cellular Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of communication devices in cellular networks leads to increased complexity and costs, with potential congestion and high latency issues during high-demand events, as traditional cellular networks rely on unicast communication models and require extensive infrastructure, whereas broadcast networks are more efficient for multicast data transmission.
Innovation Solution
A base station that integrates a data interface to communicatively couple with both broadcast and cellular networks, utilizing a controller and RF circuit to process and transform signals for efficient data transmission, and an antenna to emit and receive signals, allowing for the sharing of infrastructure and reducing the need for multiple base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional cellular networks use unicast communication model to serve increasing number of communication devices, then the network can provide individualized service to each device, but the network complexity and infrastructure costs increase significantly
Solution Approach 1:
The patent combines broadcast network infrastructure with cellular network functionality, allowing the cellular network to leverage the broadcast network's efficient multicast transmission capabilities while maintaining individualized service through hybrid communication modes. This merging reduces the need for separate infrastructure and lowers overall network complexity.
Solution Approach 2:
The base station is designed to support both unicast and multicast/broadcast communication modes, making it a multi-functional device that can adapt to different service requirements. This universality allows the same infrastructure to handle both individualized services and efficient group communications, reducing overall system complexity.
2Stability of the object's composition
If cellular networks dimension infrastructure for average load, then the network can operate stably under normal conditions, but congestion and overload situations occur during high-demand events
Solution Approach 1:
The network dynamically switches between unicast and multicast/broadcast modes based on real-time load conditions. During normal operation, unicast provides stable individualized service; during high-demand events, the system transitions to multicast/broadcast mode to efficiently handle large numbers of concurrent users, thus adapting network capacity to actual demand.
Solution Approach 2:
The network changes operational parameters by switching communication modes (unicast vs. multicast/broadcast) and adjusting resource allocation based on load conditions. This parameter change allows the network to scale capacity dynamically without over-provisioning infrastructure for peak loads that occur infrequently.
3Productivity
If more capable transmitters are provided to serve increased number of devices, then the network can handle higher traffic demand, but the costs and power consumption of transmitters increase
Solution Approach 1:
The broadcast network acts as an intermediary that handles the bulk of data transmission for multicast services, allowing the cellular network to offload traffic and avoid deploying additional high-capacity transmitters. This intermediary approach enables efficient group communication without requiring proportional increases in cellular transmitter capability.
4Area of stationary object
If smaller cells are provided to serve increased number of communication devices, then the network can provide better service coverage, but the network complexity and infrastructure costs increase
Solution Approach 1:
The patent merges cellular base stations with broadcast transmitters, allowing existing broadcast infrastructure to provide wide-area coverage while cellular components provide localized high-capacity access. This combination avoids the need to deploy numerous small cellular cells, reducing infrastructure complexity while maintaining coverage quality.
