Hash-Based Signaling for Faster Wireless Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless telecommunications systems, such as UMTS networks, face significant connection configuration times due to the large amount of data required for message exchanges between user equipment and network resources, leading to prolonged setup times.
Innovation Solution
The method involves using hash values as a compact representation of connection configuration information, allowing for reduced message sizes and the potential omission of messages by comparing hash values between network resources and user equipment, thereby minimizing data transfer and optimizing signaling delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large amounts of data are sent as set up messages between user equipment and network resources, then connection configuration information is complete and accurate, but connection configuration time becomes significant and prolonged
Solution Approach 1:
The patent extracts only the essential identification information (hash values) from the complete connection configuration messages. Instead of transmitting full configuration messages, the system sends compact hash values that represent the configuration state, thereby reducing transmission data volume while maintaining the ability to verify configuration completeness and accuracy.
Solution Approach 2:
The patent transforms the connection configuration information from its original full-message form into a condensed parameter form (hash values). This parameter transformation maintains the informational content's verification capability while dramatically reducing the data size that needs to be transmitted, thus resolving the contradiction between information completeness and transmission time.
2Reliability
If many messages are transferred between user equipment and network resources, then connection configuration information is comprehensive, but the amount of data to be transferred increases significantly
Solution Approach 1:
The patent uses hash values as compact representations (copies) of the complete connection configuration messages. These hash copies contain sufficient information to verify the configuration state without requiring transmission of the full original messages, thus reducing data transfer volume while maintaining verification comprehensiveness.
Solution Approach 2:
The patent segments the connection configuration information into two parts: the actual configuration data (transferred once initially) and the verification data (hash values, transferred subsequently). This segmentation allows the system to minimize repeated data transfer while maintaining the ability to verify configuration comprehensiveness through hash comparison.
3Reliability
If full connection configuration messages are transmitted, then data integrity is ensured, but message size and transmission time increase
Solution Approach 1:
The patent extracts the essential integrity verification component (hash value) from the complete configuration messages. By transmitting only these extracted hash values rather than full messages, the system reduces message size while maintaining the ability to verify data integrity through hash comparison between transmitted and received configurations.
