Solution Overview
Problem
Existing 3G networks require manual configuration and centralized control for handover processes, limiting scalability and flexibility in deploying femto cells, especially in enterprise environments.
Innovation Solution
An enterprise network configuration that enables decentralized handover processes through self-discovery and auto-configuration, allowing radio nodes to dynamically adjust operational parameters and perform handoffs without a designated central controller, using network relation tables generated from received network information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration and centralized control are used for handover processes, then call continuity is maintained, but scalability and flexibility in deploying femto cells are limited
Solution Approach 1:
The centralized controller function is segmented and distributed to individual radio nodes. Each radio node maintains its own network relation table and can independently perform handover decisions, eliminating the single point of control while maintaining call continuity through distributed intelligence
Solution Approach 2:
Radio nodes automatically discover neighboring nodes and generate their own network relation tables without manual configuration. The system self-organizes through automatic node discovery and table generation, enabling flexible deployment while maintaining reliable handovers through autonomous operation
2Stability of the object's composition
If manual configuration is used for network setup, then initial network stability is achieved, but deployment time and complexity increase
Solution Approach 1:
Network relation tables are pre-generated automatically when radio nodes discover each other during initial deployment. This preliminary automatic configuration establishes stable network relationships without manual intervention, reducing deployment time while maintaining network stability through systematic table generation
Solution Approach 2:
The network performs self-configuration through automatic node discovery and network relation table generation. Each radio node autonomously builds its routing information, eliminating manual configuration requirements while ensuring network stability through structured automatic setup procedures
3Ease of operation
If centralized control is implemented, then handover coordination is simplified, but device complexity and configuration requirements increase
Solution Approach 1:
The centralized handover coordination function is segmented and distributed to each radio node. Each node maintains local network relation tables and makes independent handover decisions based on its own routing information, simplifying the operational complexity by eliminating the need for centralized coordination while distributing the intelligence
Solution Approach 2:
Network relation tables serve as intermediary data structures that enable distributed radio nodes to coordinate handovers autonomously. Each node uses its local table containing neighboring node information to make handover decisions without direct centralized control, reducing device complexity while maintaining coordinated operation

AI summary
A method for configuring a network is described, the method comprising: receiving, from a first radio node in the network, network information associated with one or more second radio nodes in the network; generating a network relation table, the network relation table comprising network information associated with the first radio node and the one or more second radio nodes; and performing a handoff to a third radio node in the network using the network relation table.
