Solution Overview
Problem
The complexity and cost of constructing and maintaining mobile networks are heightened by the need for extensive transmission lines connecting core networks with base stations, regardless of whether wire or wireless communication is used, due to the requirement for large-scale core networks to process data from all base stations.
Innovation Solution
A communication network configuration where base stations can transmit and receive data wirelessly with each other, utilizing antennas, data conversion means, communication means for demodulation and modulation, and transfer means to recognize communication destinations and manage data transfers, eliminating the need for core network transmission lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large-scale core network is constructed to process data from all base stations, then data processing capability is improved, but equipment cost and system complexity increase substantially
Solution Approach 1:
The patent segments the centralized core network function into distributed base station units. Each base station independently processes and forwards data packets without requiring a centralized core network, thereby reducing system complexity while maintaining data processing capability through distributed architecture
Solution Approach 2:
The patent extracts the core network component entirely from the system architecture. By removing the centralized core network and enabling base stations to function independently with direct peer-to-peer communication, the system achieves simpler configuration and reduced equipment costs while preserving essential data processing functions
2Productivity
If transmission lines are laid down to connect core network with base stations, then data transmission capability is improved, but construction and maintenance costs increase substantially
Solution Approach 1:
The patent replaces the mechanical transmission line infrastructure with wireless communication between base stations. By substituting physical cable connections with wireless data transmission, the system eliminates construction and maintenance costs associated with laying transmission lines while maintaining full data transmission capability
Solution Approach 2:
The patent removes the transmission line infrastructure from the system by enabling direct wireless communication between base stations. This extraction of the physical connection layer simplifies the overall system architecture and eliminates associated construction and maintenance expenses

Data Source
AI summary
A communication network includes base stations. Each base station includes a BS function unit, a terminal function unit, a transfer unit, and an antenna. The antenna receives first uplink data from a subscriber terminal and downlink data transmitted from another base station and transmits downlink data to another base station or a subscriber terminal. The terminal function unit converts the downlink data received by the antenna to second uplink data. The BS function unit demodulates and outputs the first uplink data or the second uplink data as first data, and modulates input second data into downlink data and transmits the downlink data from the antenna. The transfer unit recognizes a communication destination of the first data, and, when a transfer of the first data is required, outputs the first data to the BS function unit as second data.
