Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications networks, channel switching between dedicated and common transport channels can cause latency issues in applications like gaming and VoIP, leading to degraded user experience due to bursty packet delivery and high round trip times.
Innovation Solution
A method and entity that determine a threshold value for channel switching parameters, monitor traffic, and add additional traffic to prevent channel switching, ensuring continuous occupancy of dedicated channels, thereby minimizing latency and bursty packet delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If channel switching from dedicated to common transport channel is performed when throughput falls below threshold, then network resources are released back to the network, but latency increases and user experience degrades in gaming and VoIP applications
Solution Approach 1:
The system performs preliminary actions by starting a timer when throughput falls below the first threshold, and pre-calculates whether channel switching is necessary before actually switching. This allows the system to evaluate the duration of low throughput conditions and make informed decisions about channel switching, preventing premature switching that would cause latency issues in time-sensitive applications.
Solution Approach 2:
The system dynamically adjusts channel switching behavior based on real-time throughput monitoring and timer evaluation. Instead of immediately switching channels when threshold is crossed, the system adapts its decision based on how long the throughput remains below threshold, enabling flexible response that balances resource release with maintaining service quality for different application types.
2Productivity
If channel switching operation is triggered to release unused network resources, then network efficiency improves, but round trip time increases making gaming unplayable
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring throughput and evaluating channel switching conditions. The timer mechanism provides feedback about the duration of low throughput states, allowing the system to distinguish between temporary fluctuations and sustained low usage, thereby making intelligent decisions about when to switch channels and when to maintain dedicated channels for time-sensitive applications.
Solution Approach 2:
The system performs preliminary evaluation through the timer mechanism before executing channel switching. This preliminary action allows the network to assess whether low throughput is temporary or sustained, enabling proactive decisions that prevent unnecessary channel switches that would increase round trip time, while still releasing resources when appropriate.
3Loss of energy
If dedicated transport channel is switched to common transport channel, then network resources are seized back from user, but packet delivery becomes bursty degrading voice quality
Solution Approach 1:
The system performs preliminary evaluation using a timer to assess the duration of low throughput conditions before triggering channel switching. This preliminary action ensures that channel switching only occurs when low throughput is sustained, not during temporary dips, thereby preventing unnecessary switches that would cause bursty packet delivery and voice quality degradation while still enabling resource reclamation when appropriate.
Solution Approach 2:
The system dynamically evaluates channel switching necessity based on real-time throughput monitoring and timer expiration. This dynamic approach allows the system to adapt channel switching behavior to current network conditions, maintaining smooth packet delivery when needed while enabling resource reclamation when throughput is genuinely low and sustained.

AI summary
An entity in a telecommunications network determines a threshold value relating to a channel switching parameter that is being used by the telecommunications network to trigger a channel switching operation, and uses this threshold value and monitored traffic information to prevent a channel change from occurring, i.e. to maintain channel occupancy. A network node is adapted to remove additional traffic that has been generated by an entity in the telecommunications network to maintain channel occupancy.
