Distributed Base Station IP Allocation for Network Bottleneck Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized mobile communication networks face issues with traffic load concentration, packet processing delays, and service discontinuation due to the reliance on a single gateway, which becomes a bottleneck as the number of connected terminals increases, and communication between neighboring base stations is inefficient.
Innovation Solution
A self-configuration method for base stations in a distributed network architecture that includes optimized IP address allocation and initial configuration data acquisition, using a local manager to allocate IP addresses from an external IP network, allowing for hierarchical and dynamic management of IP addresses, reducing waste, and improving communication efficiency between base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized gateway structure is used to manage all terminal traffic, then network management is simplified, but traffic load concentration causes packet processing delays and service discontinuation risks
Solution Approach 1:
The patent segments the centralized gateway function into distributed base station entities, where each base station independently manages local IP address allocation and traffic routing. This segmentation eliminates the single-point bottleneck, distributing traffic load across multiple independent nodes, thereby maintaining service continuity even when individual base stations fail.
2Device complexity
If all traffic passes through the PDN GW to reach external networks, then centralized control is achieved, but packet transmission delay increases due to the single gateway bottleneck
Solution Approach 1:
The patent divides the traffic routing function by enabling each base station to independently allocate IP addresses and route traffic directly to external networks without funneling all traffic through a single PDN GW. This segmentation creates multiple parallel traffic paths, reducing congestion and transmission delays while maintaining centralized IP pool management.
3Device complexity
If IP addresses are allocated from a centralized IP pool, then address management is simplified, but IP address waste increases due to inefficient allocation
Solution Approach 1:
The patent implements local quality by enabling each base station to autonomously manage and allocate IP addresses from its assigned pool based on local network conditions and actual demand. This localized control allows for more efficient IP address utilization, allocating addresses only when needed and releasing them when no longer required, thereby reducing waste while maintaining simplified centralized pool management.
4Device complexity
If neighboring base stations communicate through the PDN GW, then network topology is simplified, but communication efficiency decreases due to suboptimal routing paths
Solution Approach 1:
The patent segments the routing function by enabling direct peer-to-peer communication between neighboring base stations for local traffic exchange, eliminating the requirement to route all communications through the centralized PDN GW. This creates optimized local routing paths that improve communication efficiency while maintaining the simplified overall network topology through standardized interfaces.

AI summary
An embodiment of the present invention provides a method for transmitting configuration information by a local administrator and the local administrator transmitting the configuration information, the method comprising the steps of: receiving an internet protocol pool (IP pool) allocated by an IP address management server of an external IP network; receiving an IP address allocation request from a new base station in the distribution network; and, in response to the received IP address allocation request, allocating the base station a certain IP address on the basis of the allocated IP pool. In addition, the embodiment of the present invention provides a base station for receiving configuration information from the local administrator and a self-configuration method for the base station.
