Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In 5G communication systems, connection establishment delays occur due to DNS query responses and redirect generation, leading to increased webpage loading times and decreased Quality of Experience (QoE) for users.

Innovation Solution

A proxy device manages DNS query result information and redirect information to minimize delays by generating and updating DNS query information, establishing connections based on pre-generated data, and optimizing DNS query responses to reduce latency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If DNS query responses and redirect generation are performed in conventional manner, then connection establishment can be achieved, but connection establishment delays occur leading to increased webpage loading times

Engineering Contradiction:

Improveconnection establishment delayVSAvoidwebpage loading speed

Core Design Contradiction:

Loss of timeVSProductivity

Solution Approach 1:

The proxy device performs preliminary DNS queries and generates redirect information in advance before actual connection requests are made. By pre-resolving domain names to IP addresses and pre-generating redirect data, the system eliminates the need for real-time DNS resolution during user connections, significantly reducing connection establishment delays and improving webpage loading speed.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If DNS queries are performed for each connection request, then accurate server addressing is achieved, but connection establishment delays increase

Engineering Contradiction:

Improveserver address accuracyVSAvoidDNS query response time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The proxy device performs DNS queries in advance and stores the resolved IP address mappings in its memory. When connection requests are received, the proxy device retrieves pre-resolved addresses from its stored data rather than performing new DNS queries, thereby maintaining accurate server addressing while eliminating DNS query response delays.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If redirect information is generated in real-time, then accurate server redirection is achieved, but redirect-related delays occur

Engineering Contradiction:

Improveredirect accuracyVSAvoidredirect generation delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The proxy device generates redirect information in advance by performing preliminary DNS queries and storing the redirect mappings. When redirection is needed, the proxy device retrieves pre-generated redirect information from its stored data, ensuring accurate server redirection while eliminating real-time redirect generation delays.

AI summary

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Disclosed is a method of operating a proxy device in a communication system. The method includes: receiving information on at least one domain name from an external server; generating connection information on the at least one domain name; receiving a domain name system (DNS) query message including one of the at least one domain name from a client device; and establishing a connection to a server corresponding to the domain name included in the DNS query message based on the connection information.
