Wireless Service Selection via Standard and Extended Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in specifying and connecting to the desired service among various services, including vendor-specific services, when using a mobile terminal with wireless communication, as existing methods do not effectively differentiate between standard and extended services.
Innovation Solution
A communication apparatus with a connection unit, search unit, determination unit, and transmission unit that searches for external apparatuses before connecting to a wireless network, determines the type of service provided, and requests either standard or extended services based on availability, facilitating communication through the wireless network.

Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile terminal connects to a wireless network and searches for services in the network, then the terminal can find available services, but it becomes troublesome for the user to specify the desired service among various services including vendor-specific services
Solution Approach 1:
The patent segments services into two distinct categories: standard services (defined by communication standards) and extended services (vendor-specific). This segmentation allows the system to present services in an organized manner, enabling users to easily identify and select standard services while still providing access to extended services when needed, thereby reducing service selection complexity while maintaining service availability
Solution Approach 2:
The patent performs preliminary classification of services before presenting them to the user. The determination unit pre-identifies whether each service is a standard service or an extended service, and the transmission unit prepares appropriate requests in advance. This preliminary action reduces the cognitive load on users during service selection, making the operation easier while preserving access to diverse services
2Adaptability or versatility
If the system prioritizes extended services over standard services, then higher functionality is achieved, but compatibility issues may arise when extended services are not available
Solution Approach 1:
The patent implements a dynamic service selection mechanism where the system adaptively switches between extended services and standard services based on availability. The determination unit dynamically assesses whether an extended service is available, and if not, automatically falls back to requesting a standard service. This dynamic adjustment ensures both high functionality when extended services are available and reliable connection when they are not
Solution Approach 2:
The patent changes the service request parameter based on service availability. When an extended service is determined to be available, the transmission unit requests the extended service for higher functionality. When the extended service is not available, the system changes the parameter to request the standard service instead, ensuring connection reliability. This parameter change strategy balances functionality and reliability

AI summary
A communication apparatus searches for an external apparatus prior to connecting to a wireless network, determines a service provided by the searched external apparatus, transmits a request, based on the determined service, and connects, when the request for utilizing the service is accepted, to the wireless network to establish communication with the external apparatus through the wireless network.
