Media Gateway Load Sharing Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional telecommunications systems with 1:1 or 1:N protection schemes require costly redundancy and experience long delays and service degradation during switchover of communication sessions due to the need for large numbers of standby resources.
Innovation Solution
Implementing a load sharing control system within the media gateway that actively distributes processing load among all resources, eliminating the need for idle standby resources and enabling instantaneous redistribution of sessions upon failure, thereby reducing switchover delays and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional 1:1 or 1:N protection schemes are implemented with standby resources, then system reliability is improved, but device complexity and cost increase due to redundant resources
Solution Approach 1:
The patent merges the functions of active and standby resources by allowing all resources to actively process communication sessions simultaneously. Resources dynamically share the load and can immediately take over when another resource fails, eliminating the need for dedicated standby resources while maintaining system reliability.
Solution Approach 2:
Each resource in the system is designed to be universal and multi-functional, capable of both processing communication sessions and providing protection functions. This eliminates the need for specialized standby resources, as any resource can assume the role of protecting any other resource, thereby reducing overall system complexity.
2Reliability
If traditional protection schemes use standby resources, then system reliability is improved, but switchover time increases causing service degradation
Solution Approach 1:
The system performs preliminary actions by maintaining all resources in an active state with current session processing capabilities. When a failure occurs, the switchover is immediate because the backup resources are already prepared and actively processing sessions, eliminating the delay associated with activating standby resources.
Solution Approach 2:
The patent ensures continuity of useful action by having all resources continuously active and processing communication sessions. This eliminates idle periods and ensures that when a resource fails, another resource can immediately take over without interruption, thereby minimizing switchover time and preventing service degradation.
3Reliability
If standby resources are implemented for protection, then system reliability is improved, but cost increases due to resource redundancy
Solution Approach 1:
The patent combines the protective function with the active processing function, so that the same resources serve both purposes. This eliminates the need for separate standby resources, reducing the total quantity of resources required while maintaining system reliability.
4Productivity
If all resources are actively processing sessions, then resource utilization efficiency is improved, but system reliability worsens when a failure occurs
Solution Approach 1:
The system implements dynamic resource allocation where resources can transition between processing modes based on real-time conditions. When a resource fails, the system dynamically redistributes its load to other active resources, maintaining both high utilization efficiency and system reliability through adaptive resource management.
