Application Server Device Capability Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with varying capabilities face inconsistent user experiences due to lack of tailored services from application servers, which do not account for hardware and software differences across devices.
Innovation Solution
A database storing capability information for mobile devices allows application servers to tailor services by querying device capabilities, adjusting user interfaces, processing ratios, and application provisioning based on device attributes like screen size, processor type, and input mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If application servers provide standardized services to all mobile devices, then service deployment is simple and consistent, but user experience is not optimized for device-specific capabilities
Solution Approach 1:
The system performs preliminary action by establishing a database of device capabilities before service delivery. Capability information is collected and stored in advance, allowing application servers to retrieve and utilize this information when providing services, thereby enabling optimized service delivery without adding complexity during the service execution phase
Solution Approach 2:
A capability database is introduced as an intermediary component between mobile devices and application servers. This intermediary stores and manages device capability information, allowing application servers to access device-specific information without directly managing device complexity, thus resolving the contradiction between adaptability and system complexity
2Adaptability or versatility
If application servers query and store capability information for all devices, then service tailoring is enabled, but data storage and management requirements increase
Solution Approach 1:
The system extracts only the necessary capability information from comprehensive device specifications and stores only these extracted attributes in the capability database. By taking out only the essential capability parameters rather than storing complete device information, the system enables service tailoring while minimizing data storage requirements
3Ease of operation
If application servers customize services based on device capabilities, then user experience is optimized, but service provisioning complexity increases
Solution Approach 1:
The capability database performs self-service by automatically storing and managing device capability information without requiring manual configuration or complex provisioning processes. Application servers simply query the database for required capability information, enabling customized services while keeping provisioning processes simple and automated

AI summary
Capability information, relating to hardware and/or software capabilities of different types of mobile devices, may be used to tailor services provided to the mobile device based on the particular type of mobile device. In one implementation, a device, such as an application server that provide services to mobile devices, may: receive a request from a mobile device, for services; obtaining information indicating a type of the mobile device; obtain, based on the type of mobile device, information indicating capabilities of the mobile device; and provide the services to the mobile device, in which the provided services are tailored for the mobile device based on the capabilities of mobile device.
