Wireless Terminal Management Across Network Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management apparatuses for wireless communication networks struggle to maintain communication quality when wireless terminals leave one network to form another, as they are not designed to manage information on terminals that have transitioned to a new network, leading to potential degradation in communication quality across multiple networks.
Innovation Solution
A management apparatus connected to a base station that manages attribute information and network information for wireless terminals within a first network, and updates this information when a wireless terminal from the first network forms a new network, allowing for continued management and optimization of both networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a management apparatus manages only wireless terminals within the same network, then the management complexity is reduced, but the ability to maintain communication quality when terminals move between networks is lost
Solution Approach 1:
The management apparatus is designed to perform multiple functions: it manages wireless terminals within its own network and also manages terminals that have moved to other networks. This multi-functionality allows a single apparatus to maintain communication quality across network transitions without requiring separate management systems for each network.
Solution Approach 2:
The management apparatus acts as an intermediary between different wireless networks. It receives notifications from base stations about terminal movements, stores this information, and provides it to other networks, thereby mediating the coordination required when terminals move between networks and maintaining overall communication quality.
2Reliability
If wireless base stations individually set network information, then each network can operate independently, but the overall communication quality of multiple wireless communication networks degrades
Solution Approach 1:
The management apparatus implements a feedback mechanism where base stations notify the management apparatus of terminal connections and movements. This feedback loop allows the management apparatus to track terminal locations across networks and coordinate network information accordingly, maintaining overall communication quality while preserving individual network independence.
Solution Approach 2:
The management apparatus merges the management functions of multiple wireless networks into a single coordinated system. By collecting network information from various base stations and terminals in one centralized management structure, it enables coordinated control that improves overall communication quality without requiring each base station to independently manage all networks.
3Adaptability or versatility
If wireless terminals leave a network to form a new network, then network flexibility and adaptability improve, but information management on the moved terminals becomes lost
Solution Approach 1:
The management apparatus performs preliminary actions by storing terminal information and network configuration data before terminals leave a network. When terminals move to form new networks, the management apparatus has already captured the necessary information, allowing it to continue managing these terminals and providing coordinated control across network transitions.
Solution Approach 2:
The management apparatus receives feedback notifications from base stations when terminals connect and move between networks. This feedback mechanism ensures that terminal information is continuously updated and maintained in the management apparatus's database, preventing information loss even when terminals leave original networks to form new ones.

AI summary
The invention makes it possible to manage, even if some of wireless terminals leave a wireless communication network to be managed, the wireless terminals which have left. The invention provides a management apparatus which is connected to an AP and manages each wireless terminal communicating with the AP by using a management table, including a unit for determining based on the management table, when a wireless terminal leaves the first wireless communication network to newly form the second wireless communication network, the SSID of the second wireless communication network, a unit for updating the management table with the determined SSID, and a unit for transmitting the determined SSID to the wireless terminal which is to form the second wireless communication network.
