Dynamic IP Address Configuration for Base Station Sub-Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, particularly in IP transport networks, the existing methods for configuring IP addresses are inefficient, leading to a high demand for public IP addresses and increased complexity when connecting multiple base station nodes, which can result in address overlap and require manual configuration.
Innovation Solution
A method for configuring temporary addresses in a packet-switched data communication system by using a logical network with network elements and sub-elements, where a temporary address is created for an interface of a sub-element, and an identifier of the network element is retrieved to define a unique address, allowing dynamic creation of link-layer and IP addresses based on hardware location or serial numbers, reducing the need for manual configuration and avoiding address overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of IP addresses is used for each base station node, then address uniqueness can be ensured, but the complexity of network configuration increases significantly
Solution Approach 1:
The base station node automatically generates its own unique IP address by combining a subnet prefix with its own identifier (such as serial number or hardware location). This self-service mechanism eliminates the need for manual configuration while ensuring address uniqueness through the use of node-specific identifiers that are inherently unique to each device.
2Adaptability or versatility
If public IP addresses are assigned to each base station node, then each node can communicate independently, but the demand for public IP addresses increases
Solution Approach 1:
The IP address space is segmented into a subnet prefix portion and a node identifier portion. Multiple base station nodes share a common subnet prefix, reducing the need for unique public IP addresses. Each node's identifier segment ensures unique identification within the subnet, allowing independent communication while conserving public IP address resources through shared addressing.
3Productivity
If dynamic address generation is implemented, then manual configuration is eliminated, but address overlap may occur without proper verification
Solution Approach 1:
The system performs preliminary verification by checking whether the generated IP address (combination of subnet prefix and node identifier) already exists in the network before finalizing the address assignment. This preliminary action prevents address overlaps by detecting conflicts in advance, ensuring both configuration efficiency and address uniqueness.

AI summary
The present invention relates to a method for configuring addresses in a packet switched data communication system. The method comprises providing a logical network with at least two network elements, a network element comprising at least one sub-element. The method further comprises configuring a temporary address for an interface of a sub-element, retrieving an identifier of the network element and defining an address for the interface of the sub-element by including the identifier of the network element to the temporary address.
