Dynamic ENUM NAPTR Records for Tailored Communication Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia communication systems, such as IMS networks, do not effectively provide tailored communication services for subscribers with disabilities, leading to inefficiencies and unnecessary traffic delays due to the lack of dynamic mechanisms for managing communication modes.
Innovation Solution
The implementation of a dynamic ENUM system that modifies naming authority pointer records based on subscriber-selected communication modes, allowing for optimized multimedia communication services by prioritizing preferred communication methods, such as voice-only or text-only options, and reducing unnecessary traffic by skipping presence servers when presence is not required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional ENUM system is used for multimedia communication, then basic communication services are provided, but tailored services for subscribers with disabilities cannot be effectively provided and unnecessary traffic delays occur
Solution Approach 1:
The patent implements a dynamic ENUM system that modifies naming authority pointer records in real-time based on subscriber-selected communication modes. The system dynamically updates NAPTR records to reflect current subscriber preferences and capabilities, enabling adaptive routing decisions that eliminate unnecessary traffic delays while providing tailored services for subscribers with disabilities.
Solution Approach 2:
The system performs preliminary action by pre-configuring and storing multiple communication mode preferences for subscribers in the ENUM database. When a communication request is received, the system queries pre-stored subscriber profiles and NAPTR records to determine the appropriate communication mode before routing, thereby avoiding delays that would occur with real-time decision-making.
2Reliability
If presence servers are contacted for every communication query, then complete presence information is obtained, but traffic efficiency is reduced when presence is not required
Solution Approach 1:
The patent extracts and utilizes existing presence information from ENUM NAPTR records and subscriber profiles before contacting presence servers. By taking out and leveraging already-available presence data from the ENUM system's naming authority pointer records, the system can make routing decisions without necessarily querying presence servers for every communication query, thereby improving traffic efficiency while maintaining reliable presence information.
Solution Approach 2:
The ENUM system acts as an intermediary that mediates between communication requests and presence server queries. It uses NAPTR records as an intermediate layer to determine appropriate routing and presence information needs, filtering out unnecessary presence server contacts while ensuring accurate presence information is obtained only when required.

AI summary
A technique for providing multimedia communication services to a subscriber includes receiving a communication query for the subscriber, the communication query having an associated requested communication mode. The technique also includes servicing the communication query for the subscriber using the requested communication mode when the requested communication mode corresponds to one of one or more selected communication modes.
