Dynamic Trunk Resource Allocation for Network Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telephony networks face inefficiencies due to the permanent or semi-permanent nature of trunk group resource allocation, leading to idle resources during low traffic periods and slow reaction to changing traffic patterns, resulting in wasted resources and potential dropped calls during peak demand.
Innovation Solution
A method for dynamically allocating trunk resources by monitoring traffic volume, selecting and negotiating bearer paths, and associating them with available trunk members, allowing for real-time adjustment of network resources to match demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trunk groups are provisioned on a permanent or semi-permanent basis to ensure sufficient capacity during peak traffic, then call connectivity is improved, but network resources remain idle during low traffic periods
Solution Approach 1:
The patent implements dynamic trunk group provisioning where the system automatically adds or removes trunk members based on real-time traffic conditions. During peak traffic periods, additional trunks are activated to maintain call connectivity, while during low traffic periods, trunks are deactivated to eliminate resource waste. This dynamic adjustment resolves the contradiction between ensuring reliable connectivity and optimizing resource utilization.
Solution Approach 2:
The system changes the operational parameters of trunk groups by adjusting the number of active trunk members based on traffic demand. The controller monitors traffic volume and modifies trunk group configuration parameters in real-time, transitioning from static permanent provisioning to dynamic parameter adjustment, thereby resolving the contradiction between reliability and resource efficiency.
2Reliability
If craft personnel manually reprovision network resources to accommodate increased traffic demand, then trunk group capacity is increased, but response time is delayed
Solution Approach 1:
The patent implements an automated system where the network controller independently monitors traffic conditions and performs trunk group provisioning without human intervention. When traffic demand increases, the system automatically detects the condition, selects appropriate trunk members, and activates them to maintain capacity. This self-service automation eliminates the time delay associated with manual craft personnel intervention while ensuring reliable capacity management.
Solution Approach 2:
The system continuously monitors traffic volume and uses this feedback to automatically adjust trunk group configuration. The controller receives real-time traffic data, processes it according to provisioning criteria, and automatically modifies trunk member allocation. This closed-loop feedback mechanism ensures rapid response to changing traffic conditions without manual intervention, resolving the contradiction between maintaining capacity and reducing response time.
3Loss of energy
If a common pool of interfaces and network resources is dynamically allocated, then resource utilization is optimized, but system complexity increases
Solution Approach 1:
The patent introduces a controller as an intermediary between the common pool of network resources and the trunk groups. The controller manages the complexity of dynamic resource allocation by centralizing the decision-making logic, monitoring traffic conditions, and automatically selecting and activating appropriate trunk members from the common pool. This intermediary approach optimizes resource utilization while containing system complexity within the controller rather than distributing it throughout the network.

AI summary
A pool of network resources is provided. Traffic volume between switches is monitored. When traffic volume between two switches justifies the allocation of pool resources a switch-to-switch call is made between the two switches. One or more resources from the pool are used to establish the switch-to-switch call. The switch-to-switch call is used to carry call traffic. When traffic volume subsides, the switch-to-switch call is torn down, thereby freeing the one or more resources for use in the dynamic establishment of other switch-to-switch calls between other switch pairs. Switch-to-switch calls are placed ISUP in TDM bearer networks, using SIP or BICC in IP bearer networks and using BICC in ATM bearer networks.
