SMS-Based Host Name Resolution for Mobile DNS Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication networks, existing DNS resolver services face inefficiencies and errors when resolving host names, requiring re-iterative mechanisms and managing multiple UDP channels, which can lead to connectivity issues and increased resource utilization.
Innovation Solution
A processing module and host name resolution server system that uses the Short Message Service (SMS) to request and transmit IP addresses associated with host names, allowing for efficient resolution and communication between mobile devices and DNS servers, reducing the reliance on conventional DNS protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional DNS resolver services are used to resolve host names in mobile communication networks, then IP addresses can be obtained for communication, but the system requires re-iterative mechanisms and manages multiple UDP channels which increases device complexity and reduces reliability
Solution Approach 1:
The patent introduces an SMS gateway as an intermediary component that mediates between the mobile device and the DNS resolver server. The gateway translates DNS resolution requests into SMS messages, allowing communication over the more reliable SMS protocol instead of requiring complex UDP channel management. This intermediary approach maintains reliability while simplifying the device's communication infrastructure.
2Productivity
If conventional DNS protocols are used for host name resolution, then IP addresses can be obtained, but multiple UDP channels must be managed which increases resource utilization and connectivity issues
Solution Approach 1:
The patent replaces the mechanical UDP channel management system with an SMS-based communication system. Instead of managing multiple UDP channels for DNS queries and responses, the system uses SMS messages which are handled by the mobile device's existing SMS infrastructure. This substitution eliminates the need for complex channel management while maintaining resolution efficiency.
3Reliability
If re-iterative DNS resolution mechanisms are implemented to handle errors, then host name resolution can be achieved, but the process requires multiple attempts and channels increasing complexity and resource usage
Solution Approach 1:
The SMS gateway acts as a reliable intermediary that handles error management and retry logic on the server side rather than requiring complex re-iterative mechanisms in the mobile device. The gateway ensures proper message delivery and can implement retry logic centrally, simplifying the device's resolution mechanism while maintaining high success rates.
Data Source
AI summary
A method for transmitting an IP data packet to an IP address associated with a host name is described. A first service message of a Short Message Service is transmitted to a Short Message Service gateway server. The first service message includes a host name resolution request for a host name. A second service message of the Short Message Service is received from the Short Message Service gateway server. The second service message includes an IP address associated with the host name. An IP data packet is transmitted to the IP address associated with the host name.
