Communication Apparatus Dynamic Operator Selection via Profile Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices often cannot switch to more suitable communication operators even when they are within their service area due to lack of stored profiles, limiting their ability to utilize better communication conditions.
Innovation Solution
A communication apparatus and management system that extract wireless network identifiers from notification signals, confirm the presence of more suitable operators, request and update communication profiles from subscription management systems, and manage profile assignments based on location-specific conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication profiles are stored in advance by the supplier, then the wireless communication apparatus can communicate using pre-configured operators, but it cannot switch to more suitable communication operators even when available in the current location
Solution Approach 1:
The system performs preliminary actions by storing multiple communication profiles in advance and establishing a mechanism where the management apparatus proactively provides updated profiles based on location information, enabling the device to switch operators without requiring complex real-time profile acquisition logic
Solution Approach 2:
A management apparatus is introduced as an intermediary between the wireless communication apparatus and communication operators. This mediator handles the complex tasks of acquiring, validating, and providing communication profiles based on location information, thereby simplifying the device's profile management complexity while enhancing its adaptability
2Reliability
If the wireless communication apparatus uses only pre-stored communication profiles, then the device structure remains simple, but communication quality is limited when not in the optimal operator's service area
Solution Approach 1:
The system implements self-service by having the wireless communication apparatus automatically monitor its location, query the management apparatus for suitable communication profiles, and switch operators without manual user intervention. This maintains ease of operation while significantly improving communication quality through automatic optimization
Solution Approach 2:
The management apparatus receives location information from the wireless communication apparatus and provides feedback in the form of recommended communication profiles. This feedback loop enables the system to adapt to changing locations and maintain optimal communication quality automatically
3Adaptability or versatility
If communication profiles are updated dynamically based on location, then the device can use more suitable operators, but the system complexity increases due to continuous profile management
Solution Approach 1:
The management apparatus serves as a centralized intermediary that handles all complex profile management tasks including acquiring profiles from operators, validating their suitability based on location, and delivering them to the wireless communication apparatus. This separation of concerns enables location-based adaptability while containing system complexity in the management layer rather than the device

AI summary
A communication apparatus extracts a wireless network identifier from a received notification signal; based on the extracted wireless network identifier, confirms whether or not there is present a second communication operator, among communication operators other than a first communication operator of a wireless network currently being used, that is currently usable and satisfies a predetermined condition; and in the case where its presence is confirmed, makes a request for a communication profile to a subscription management apparatus that manages a communication profile for the second communication operator.
