Solution Overview

Problem

Current self-organizing wireless networks rely on local data processing at base stations, limiting the management and optimization of wireless communication systems, as centralized SON functions are mainly focused on policy management and aggregate parameters, lacking comprehensive management across the network.

Innovation Solution

Implementing a cloud-based management system that collects and analyzes data from multiple radio nodes and mobile devices to provide centralized, non-real-time optimization and management of self-organizing wireless networks, using a cloud server with components for network information collection, mobile information collection, information analysis, network optimization, and communication to make global improvements in network performance and resource distribution.
