Telecom Resource Reservation via Unified Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QoS control methods in telecommunications networks primarily focus on transport resource management, failing to provide adequate guarantees when processing resources become a limiting factor, leading to QoS degradation despite sufficient transport capacity.
Innovation Solution
A method and network node architecture that dynamically reserve both transport and processing resources using a common signaling message, incorporating indications of required processing and transport resources, allowing for end-to-end QoS guarantees and stable operation by integrating resource reservation for traffic flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing QoS control methods focus only on transport resource management, then transport resource allocation is optimized, but QoS guarantees fail when processing resources become limiting
Solution Approach 1:
The patent applies universality by designing a signaling message structure that simultaneously handles both transport resource reservation and processing resource reservation. The common signaling message includes fields for both transport parameters (bandwidth, delay) and processing parameters (processing time, processing load), enabling a single message to reserve multiple resource types end-to-end, thus making the QoS control mechanism versatile across different resource dimensions
2Reliability
If separate messaging is used for transport and processing resource reservation, then resource reservation is possible, but signaling overhead increases and coordination becomes complex
Solution Approach 1:
The patent merges transport resource reservation and processing resource reservation into a single common signaling message. This message contains both transport-specific parameters (bandwidth, delay requirements) and processing-specific parameters (processing time, processing load) in an integrated structure, eliminating the need for separate messaging protocols and reducing signaling overhead while maintaining comprehensive resource control
3Productivity
If transport capacity is increased without processing resource reservation, then transport performance improves, but QoS degradation occurs due to processing bottlenecks
Solution Approach 1:
The patent applies preliminary action by reserving processing resources in advance along with transport resources through the common signaling message before data transmission begins. This ensures that both transport capacity and processing capacity are pre-allocated and guaranteed, preventing QoS degradation that would occur if only transport capacity were increased without corresponding processing resource availability

AI summary
Embodiments of the present invention relate to network nodes and methods that allow for improved QoS control in a telecommunications network by providing combined reservation of transport resources and processing resources for a traffic flow. The amount of transport resources and the amount of processing resources required in connection with a traffic flow can be signaled in a signaling message from a sender node to a receiver node to enable reservation of appropriate amounts of processing resources as well as transport resources.
