MGW Resource Channel Inheritance for Mobile Switch Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3G mobile communication systems, the switch procedure often results in interruptions of voice and data services due to the reconfiguration of communication links, leading to discontinuities and reduced quality of service (QoS) during handovers between cells or network bearer changes.
Innovation Solution
The method involves the MSC Server controlling the MGW to inherit the resource channel of the original termination by the new termination through a Handover Package or changes in network topology relationships, ensuring continuous communication by transferring announcement channels or IWF channels during a switch procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the MSC Server controls the MGW to establish a new termination connecting to a new ground circuit during switch, then the MS can switch to a new wireless channel, but the communication continuity is interrupted due to resource channel reconfiguration
Solution Approach 1:
The MGW establishes the new termination and connects it to the new ground circuit in advance before the MS completes the wireless channel switch. This preliminary setup ensures that when the MS switches to the new wireless channel, the resource channel is already prepared and ready for immediate inheritance, preventing communication interruption
Solution Approach 2:
The patent ensures continuous communication by making the new termination inherit the resource channel of the original termination. The voice announcement, data service, and QNC service continue without interruption as the resource channel remains active throughout the switch process, maintaining the useful action of communication
2Adaptability or versatility
If the MGW establishes a new termination with new ground circuit connections, then the network can support handover to new cells, but service establishment time increases due to resource reconfiguration
Solution Approach 1:
The MGW performs the resource channel setup in advance by establishing the new termination and connecting it to the new ground circuit before the handover is fully executed. This eliminates the need for time-consuming resource reconfiguration after the MS switches wireless channels, significantly reducing service establishment time
Solution Approach 2:
The new termination copies the resource channel configuration from the original termination. Instead of creating a completely new resource channel setup, the system replicates the existing working resource channel to the new termination, which dramatically reduces the time required for service establishment during handover
