Route Control Device for Signal Transfer Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing signal transfer systems require a large number of network nodes (NNIs) due to varying frequency bandwidths among service providers, leading to inefficient signal distribution and increased infrastructure needs.
Innovation Solution
A signal transfer system with a route control device that adjusts the MBH band for each UNI based on correspondence relation information and traffic data, determining optimal signal distribution across NNIs to reduce the number of required network nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the MBH band is broadened to accommodate varying frequency bandwidths of service providers, then the number of required NNIs increases, but signal transfer capacity is improved
Solution Approach 1:
The patent merges multiple UNI signals from different service providers into fewer NNI outputs by dynamically adjusting bandwidth allocation. The signal distribution unit combines signals based on real-time traffic conditions, allowing multiple input signals to share common output paths, thereby reducing the total number of NNIs required while maintaining adequate transfer capacity.
Solution Approach 2:
The patent implements dynamic bandwidth adjustment where the MBH band for each UNI is adjusted based on correspondence relation information and current traffic conditions. This dynamic allocation allows the system to optimize signal distribution in real-time, enabling efficient multiplexing of signals onto fewer NNI outputs without compromising service quality.
2Device complexity
If signal distribution is optimized to reduce the number of NNIs, then infrastructure cost is reduced, but signal transfer efficiency may deteriorate
Solution Approach 1:
The patent changes the bandwidth parameter dynamically based on service provider requirements and traffic conditions. By adjusting the MBH band allocation for each UNI according to actual needs rather than using fixed allocations, the system maintains high transfer efficiency while consolidating signals onto fewer NNI outputs, thus reducing infrastructure requirements without sacrificing performance.
Solution Approach 2:
The patent incorporates feedback mechanisms where the signal distribution unit continuously monitors traffic conditions and correspondence relation information, then adjusts bandwidth allocation accordingly. This closed-loop control ensures that signal transfer efficiency is maintained even as the number of NNIs is reduced, as the system adapts to changing conditions in real-time.

AI summary
Signal transfer devices that relay base stations of service providers that perform communication with radio terminals and an aggregation station that controls the base stations, and a route control device that controls signal distribution to user network interfaces (UNIs) and network network interfaces (NNIs) of each of the signal transfer devices, are included. The route control device includes an allocation information acquisition unit that acquires allocation information of frequency to each of the base stations; a band adjustment unit that adjusts an MBH band for each of the UNIs, on the basis of correspondence relation information representing a correspondence relation between the UNIs and the service providers, band information indicating a maximum MBH band of each of the UNIs, and the allocation information; and a distribution determination unit that determines signal distribution to each of the NNIs, on the basis of the MBH band adjusted by the band adjustment unit and configuration information representing a connection configuration of each of the signal transfer devices. The signal transfer device transmits a signal from each of the NNIs on the basis of the signal distribution to each of the NNIs determined by the distribution determination unit.
