Wireless Node Status Synchronization Across Generations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, user equipment (UE) may face difficulties connecting to the network due to outdated node status information, particularly when network equipment from different generations is used, and some nodes do not automatically update their status.
Innovation Solution
The implementation of a method and system that allows for the automatic updating of node status information across different generations of network equipment, using a network repository function (NRF) to communicate with a domain name system (DNS) and ensure that only accessible nodes are listed for connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network equipment from multiple generations is utilized in a same base station, then connectivity for various user equipment is provided, but node status information may not be automatically updated causing connection difficulties
Solution Approach 1:
The patent implements a feedback mechanism where the first network equipment (newer generation) periodically sends node status information to the second network equipment (older generation). This feedback loop ensures that the second equipment receives updated status information about nodes it manages, allowing it to provide accurate connection information to user equipment even though it cannot automatically update the status itself.
Solution Approach 2:
The first network equipment acts as an intermediary between the nodes and the second network equipment. It collects status information from nodes that the second equipment cannot monitor directly and relays this information to the second equipment, enabling the older generation equipment to make informed connection decisions without having direct access to real-time node status.
2Device complexity
If node status is not automatically updated, then device complexity is reduced, but connection reliability deteriorates due to outdated information
Solution Approach 1:
The first network equipment serves as an intermediary that performs the complex task of collecting and updating node status information. The second network equipment, which lacks automatic update capability, receives this processed information from the intermediary, thereby maintaining connection reliability without needing to implement complex automatic update mechanisms itself.
Solution Approach 2:
The first network equipment performs multiple functions: it acts as a base station for user equipment, manages nodes in its own right, and simultaneously serves as a status information provider for the second network equipment. This multi-functionality allows the system to maintain reliability without adding complexity to the second equipment.

AI summary
A method of identifying accessible nodes for a wireless network includes storing a first list of nodes in a first device, wherein the first list includes a corresponding status of each of the nodes in the first list, and the first device usable in a first technology generation of the wireless network. The method further includes updating a second list of nodes in a second device based on the first list of nodes, wherein the second list is free of a status of each of the nodes of the second list, and the second device is usable in a second technology generation of the wireless network different from the first technology generation. The method further includes providing connection information for a node of the second list of nodes to user equipment in response to receiving a connection request from the user equipment.
