Network-Registered Device Mediator for External Media Resource Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia networks, such as IMS, lack a mechanism to register and access external media resources attached to devices, limiting the ability to utilize these resources over the network.
Innovation Solution
A method is introduced to determine and transform resource capability information into service capability information, which is then provided to the network, allowing access to media resources controllably attachable to network-registered devices via a multimedia-enabled network. This involves determining resource capability, transforming it into service capability, and providing this information to access-requesting entities, enabling network access to attached media resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external media resources are attached to network-registered devices, then the capabilities and functionality of the devices are enhanced, but the network cannot register or access these external resources
Solution Approach 1:
The patent introduces an intermediary mechanism where the network-registered device acts as a mediator between the external media resource and the multimedia network. The device registers capability information about attached resources with the network, enabling indirect access without direct network registration of external resources. This resolves the contradiction by maintaining device functionality enhancement while preserving network access capability through the intermediary role of the registered device.
Solution Approach 2:
The patent creates a virtual representation or copy of external media resources within the network registry. Instead of requiring physical or direct network registration of external resources, the system creates capability information copies that describe the resources' features and access methods. This allows the network to access and manage external resources through their informational representations, resolving the accessibility loss while maintaining functional enhancement.
2Loss of information
If a registration mechanism for external media resources is implemented, then network access to resources is enabled, but the complexity of the network protocol increases
Solution Approach 1:
The patent implements a universal registration mechanism that leverages existing SIP protocol frameworks and capability information structures already used for device registration. By reusing established protocols and data formats for multiple purposes (both device registration and resource registration), the system enables resource accessibility without significantly increasing protocol complexity. The same SIP infrastructure serves multiple functions.
Solution Approach 2:
The patent extends existing protocol parameters and capability information fields to include resource descriptions rather than creating entirely new protocol structures. By modifying and repurposing existing parameters to carry resource capability information, the system enables resource registration while minimizing increases in protocol complexity. The approach uses parameter extensions rather than structural overhauls.
3Loss of information
If capability information transformation is performed, then resource capabilities are made accessible to the network, but information processing overhead increases
Solution Approach 1:
The patent performs capability information transformation in advance during the resource attachment phase, before network access is required. The network-registered device pre-processes and transforms external resource capability information into network-compatible formats during initial registration. This preliminary action eliminates the need for repeated transformation operations during actual resource access, reducing processing overhead and energy consumption during operational phases.
