Time Slot Policy Coordination for End-to-End Bandwidth Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication networks face inefficiencies in time slot negotiation and adjustment due to hop-by-hop mechanisms, leading to inconsistent end-to-end carrier bandwidth and reduced success rates, especially when node negotiations fail, and fallback mechanisms complicate the process.
Innovation Solution
A method for time slot adjustment that involves sending policy information through downstream nodes to determine and implement adjustment policies sequentially, reducing the need for fallbacks and improving negotiation efficiency and success rates by ensuring end-to-end consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hop-by-hop negotiation and adjustment is used for time slot allocation, then each node can independently negotiate time slots, but the negotiation efficiency is low and the success rate is reduced due to multiple sequential negotiations
Solution Approach 1:
The patent segments the time slot negotiation process into two distinct phases: a policy negotiation phase where nodes agree on adjustment policies, and a policy execution phase where nodes implement the agreed policies. This segmentation allows parallel processing of negotiations across multiple nodes simultaneously, improving overall negotiation efficiency while preserving independent negotiation capabilities.
Solution Approach 2:
The patent introduces a preliminary policy negotiation phase before actual time slot adjustment execution. During this phase, all nodes along the path negotiate and agree on the adjustment policies in advance. This preliminary action ensures that when execution occurs, all nodes are synchronized and can implement changes simultaneously, avoiding the inefficiency of sequential hop-by-hop adjustments.
2Ease of operation
If hop-by-hop adjustment is performed sequentially, then each node adjusts time slots in turn, but the end-to-end carrier bandwidth becomes inconsistent during the adjustment process
Solution Approach 1:
The patent implements a feedback mechanism where nodes send acknowledgment messages to confirm policy agreement and execution status. The source node receives feedback from the destination node regarding policy acceptance, and all nodes provide feedback on execution status. This feedback loop ensures that bandwidth consistency is maintained throughout the adjustment process by coordinating changes across all nodes before actual modification occurs.
Solution Approach 2:
The patent merges the time slot adjustment operations of all nodes along the path into a single coordinated action. Instead of nodes adjusting time slots independently and sequentially, the patent combines all adjustments into one synchronized operation triggered by a single execution command. This merging ensures that end-to-end bandwidth remains consistent as all nodes transition simultaneously.
3Reliability
If fallback mechanism is employed for reverse adjustment when negotiation fails, then negotiation coverage is improved, but the negotiation process becomes more complex and success rate is reduced
Solution Approach 1:
The patent introduces dynamic policy adjustment capabilities that allow nodes to adapt negotiation parameters based on network conditions and node capabilities. Instead of rigid fallback mechanisms, the system dynamically selects appropriate adjustment policies from multiple options, simplifying the negotiation process while maintaining reliability. The source node can dynamically choose different policies based on real-time feedback from intermediate nodes.
Solution Approach 2:
The patent changes the negotiation parameters from binary success/failure outcomes to a spectrum of policy options with varying degrees of adjustment. Instead of requiring complete success or triggering complex fallback procedures, the system allows negotiation to proceed with different policy parameters (e.g., partial adjustments, deferred adjustments). This parameter change simplifies the negotiation process by eliminating the need for complex fallback mechanisms while maintaining negotiation coverage.
Data Source
AI summary
A method for time slot adjustment, a communication device and a medium. The method may include sending time slot adjustment policy information to a destination node through a downstream node, to allow each of the downstream node and the destination node to determine respective time slot adjustment policy according to the time slot adjustment policy information; and sending time slot adjustment indication information to the destination node through the downstream node, in response to receiving time slot adjustment policy acknowledgment information returned by the destination node through the downstream node, and completing the time slot adjustment by adopting the respective time slot adjustment policy.
