Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies do not adequately ensure reliable high-priority communication sessions, such as emergency calls, which require enhanced error protection to guarantee low error rates and may drain battery life due to increased processing demands.
Innovation Solution
Implementing dynamic error protection enhancement for high-priority communication sessions by using forward error correction and modifying wireless parameters, such as modulation schemes and error control coding, specifically for high-priority sessions like emergency calls, while adjusting based on channel conditions to conserve battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If enhanced error protection is applied to high priority communication sessions, then reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies enhanced error protection selectively only to high priority communication sessions (such as emergency calls) rather than all communications. The communication application identifies high priority sessions and applies forward error correction and modified wireless parameters specifically to those sessions, leaving standard error protection for regular communications. This localized application of enhanced protection resolves the contradiction by concentrating energy expenditure only where reliability is critically needed.
Solution Approach 2:
The patent dynamically adjusts error protection levels based on channel conditions. The system monitors channel quality and adapts the degree of forward error correction and modulation schemes in real-time. When channel conditions are good, less aggressive error protection is applied; when conditions deteriorate, enhanced protection is activated. This dynamic adjustment ensures reliability is maintained only when necessary, reducing unnecessary energy consumption during periods of good channel quality.
2Reliability
If forward error correction is performed on high priority communication data, then error protection is enhanced, but processing complexity increases
Solution Approach 1:
The patent implements forward error correction and systematic FEC encoding specifically for high priority communication sessions rather than all communications. The communication application identifies which sessions require enhanced protection and applies the complex processing only to those data streams. This selective application reduces overall processing complexity while maintaining enhanced reliability where it is most needed.
3Use of energy by moving object
If dynamic adjustment of error protection based on channel conditions is implemented, then energy efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic adjustment of error protection levels based on real-time channel condition monitoring. The system continuously assesses channel quality and adapts the degree of forward error correction and modulation schemes accordingly. This dynamic behavior allows the system to consume less energy during good channel conditions while maintaining reliability during poor conditions, resolving the contradiction between energy efficiency and system complexity through intelligent adaptation.

AI summary
Techniques for enhanced error protection for high priority communication sessions are described. Generally, the described techniques enhance error protection for high priority communication sessions, such as emergency calling, such that the high priority communication sessions are essentially error free. According to various implementations, user input to initiate a communication session over a network is received at a communication application. In response to detecting that the communication session corresponds to a high priority communication session, error protection for data of the high priority communication session is enhanced. The data may be enhanced in a variety of different ways, such as by performing forward error correction on the data. The enhanced data of the high priority communication session is then communicated over the network to an endpoint.
