H.248 Statistic Parameter Adjustment for QoS Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Media Gateway Control (MGC) in the H.248 protocol lacks the ability to dynamically adjust statistic parameters, limiting its control over Quality of Service (QoS) management within the media gateway (MG).
Innovation Solution
The MGC sends adjustment information to the MG, specifying the statistic parameter and adjustment manner, allowing the MG to set the value accordingly, thereby enabling dynamic adjustment of statistic parameters and enhancing QoS control and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the H.248 protocol is used for communication between MGC and MG, then standardization and interoperability are improved, but the MGC lacks the ability to dynamically adjust statistic parameters
Solution Approach 1:
The patent extends the H.248 protocol by adding a new parameter type 'StatisticAdjustment' that enables dynamic adjustment of statistic parameters. This parameter change allows the MGC to modify statistic parameter values during runtime without changing the core protocol structure, thus improving QoS control capability while maintaining protocol compatibility.
Solution Approach 2:
The patent segments the protocol extension into distinct components: a new parameter type definition, specific parameter value options (initial value, maximum value, minimum value, average value), and corresponding command structures. This segmentation allows the extension to be implemented independently without affecting the existing H.248 protocol framework.
2Ease of operation
If the MGC sends adjustment information to dynamically adjust statistic parameters, then QoS control flexibility is improved, but communication traffic increases
Solution Approach 1:
The patent implements partial action by allowing the MGC to adjust only specific statistic parameters that require modification, rather than reconfiguring all parameters. The adjustment is triggered only when QoS conditions change, reducing unnecessary communication traffic while maintaining operational flexibility.
Solution Approach 2:
The patent establishes a feedback mechanism where the MG reports statistic parameters to the MGC, and the MGC sends adjustment information only when adjustments are needed based on QoS monitoring. This feedback-driven approach minimizes communication traffic by avoiding redundant adjustment messages.
3Measurement precision
If the MGC adjusts statistic parameters in real-time, then QoS monitoring accuracy is improved, but processing complexity increases
Solution Approach 1:
The patent defines predetermined adjustment modes including initial value, maximum value, minimum value, and average value. These preliminary-defined options simplify real-time decision-making by providing pre-established adjustment strategies, reducing processing complexity while maintaining monitoring accuracy.
Solution Approach 2:
The patent enables precise QoS monitoring through dynamic parameter changes by allowing the MGC to adjust statistic parameter values in real-time based on monitored conditions. The extension supports multiple parameter types and value options, providing the flexibility needed for accurate QoS monitoring without requiring complex custom processing logic.

AI summary
The present invention relates to a method and apparatus for adjusting the value of the statistic parameter so as to enable an MGC dynamically adjust the statistic parameter under H.248 framework. The method extends the H.248 protocol. The MGC sends adjustment information to the MG. The MG adjusts the value of the specified statistic parameter in a specified adjustment manner according to the adjustment information. The adjustment manner may be direct value assignment or one adjustment operation executed by the MG combining with a local preset parameter. If the adjustment information can not be recognized or supported by the MG, or the adjustment information is not suitable for the statistic parameter, the MG returns corresponding error information to the MGC. The adjustment to the statistic parameter value by the MGC may be issued to the MG for execution at the same time with other operations such as audit.
