Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media gateway control protocols, such as H.248/MGCP, do not support the adjustment of signal delivery bandwidth, limiting the ability to change data transfer speeds for improved quality or efficiency in signal delivery.
Innovation Solution
A method and system for adjusting signal delivery bandwidth in media gateways (MG) and media gateway controllers (MGC) using extended media gateway control protocols, where MG receives and processes command requests to adjust bandwidth, ensuring uninterrupted signal execution by matching identifiers and adjusting bandwidth accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current media gateway control protocols (H.248/MGCP) are used, then device compatibility and standardization are maintained, but the ability to adjust signal delivery bandwidth is lost
Solution Approach 1:
The patent extends existing media gateway control protocols by introducing new parameters (signal delivery bandwidth, speed ratio) to existing protocol messages. This allows bandwidth adjustment capability to be added without changing the fundamental protocol structure, maintaining compatibility while enabling new functionality through parameter extension
Solution Approach 2:
The patent enables dynamic bandwidth adjustment during signal delivery by allowing the MGC to modify the speed ratio parameter of ongoing signals. This transforms the static bandwidth configuration into a dynamic, adjustable parameter that can be changed without interrupting signal execution
2Productivity
If signal delivery bandwidth is adjusted, then data transfer speed and quality are improved, but signal execution continuity may be interrupted
Solution Approach 1:
The patent applies preliminary action by having the MGC pre-calculate and prepare the speed ratio parameter before bandwidth adjustment is needed. The MGC determines the appropriate speed ratio based on the desired bandwidth change and sends this prepared parameter to the MG, ensuring the adjustment can be executed smoothly without interrupting signal delivery
Solution Approach 2:
The patent ensures continuity of useful action by designing the bandwidth adjustment mechanism to modify only the speed ratio parameter of ongoing signals rather than stopping and restarting them. The signal execution continues uninterrupted while the delivery bandwidth is adjusted through parameter modification
Data Source
AI summary
A method for adjusting a signal delivery bandwidth is provided. The method includes the following steps: A media gateway (MG) receives a command request carrying signal delivery bandwidth adjusting information, and the MG adjusts the signal delivery bandwidth according to the signal delivery bandwidth adjusting information. An MG and a media gateway controller (MGC) are also provided. By extending the media gateway control protocol (H.248 or MGCP), the delivery bandwidth adjusting information of a signal is transferred while the signal is transferred, the signal is adjusted according to the signal delivery bandwidth adjusting information, a signal and/or signal list corresponding to the signal delivery bandwidth adjusting information is transferred simultaneously, and the executing process of the signal remains uninterrupted.
