Dynamic Root Selection in Radio Base Station Tree Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems face inefficiencies in configuring and maintaining communication paths, leading to increased electricity consumption and reduced network performance due to fixed root configurations in tree networks, which prevent some nodes from communicating and require constant path maintenance.
Innovation Solution
A radio communication system with multiple base stations that dynamically configure a communication path by setting path information sequentially, allowing the radio terminal-connected base station to act as a root, and using relay communications to enable efficient communication between radio terminals and base stations, while reducing unnecessary path maintenance and electricity consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the root is fixed to the radio gateway in a tree network, then the network structure is simple to configure, but communication efficiency deteriorates because some nodes cannot communicate through the root and electricity consumption increases due to constant path maintenance
Solution Approach 1:
The patent implements dynamic root selection where any base station that receives a connection request from a radio terminal can become the root of a temporary tree network. This dynamic approach allows the network structure to adapt to current communication needs, enabling efficient communication between the radio terminal and any base station while reducing unnecessary path maintenance electricity consumption.
2Stability of the object's composition
If the root is fixed to the radio gateway, then the network topology is stable, but communication coverage deteriorates because nodes cannot communicate efficiently when the root is far away
Solution Approach 1:
The system dynamically changes the root base station based on which base station receives the connection request from the radio terminal. This allows the network topology to adapt to the radio terminal's location and communication needs, improving communication coverage while maintaining stability through structured path configuration and release mechanisms.
3Reliability
If communication paths are maintained continuously in the network, then connection reliability is high, but electricity consumption increases due to unnecessary path maintenance
Solution Approach 1:
Instead of continuously maintaining communication paths, the system dynamically configures paths only when a radio terminal connects to a base station and releases them when the terminal disconnects. This periodic path configuration and release approach maintains connection reliability when needed while significantly reducing electricity consumption during idle periods.
Solution Approach 2:
The system releases communication paths when they are no longer needed (when radio terminals disconnect), allowing base stations to conserve energy. The paths can be重新配置 when new connection requests arrive, effectively discarding unused resources and recovering them for future use.

AI summary
A radio communication system includes a first radio base station including a terminal communicator which communicates with a radio terminal and a connection timing controller which starts waiting for connection in station-to-station communication when the terminal communicator has established a communication link with the radio terminal, a second radio base station including a connector which, upon detecting the base station waiting for connection in station-to-station communication, establishes connection with the base station in the station-to-station communication and a connection timing controller which, when the connector has detected the base station, starts waiting for connection in station-to-station communication, and a third radio base station including a connector which, upon detecting the base station waiting for connection in station-to-station communication, establishes connection with the second base station in the station-to-station communication. The second base station further includes a relay which relays communication between the first base station and the third base station.
