Media Gateway Controller Package Audit Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication technologies, a Media Gateway Controller (MGC) cannot apply a base package to the control interface with a Media Gateway (MG) unless the MG has published the base package, creating a contradiction in publishing and applying packages.
Innovation Solution
The method involves delivering an audit command request by the MGC to the MG to determine the base-extended relationships of packages supported, and applying packages based on the received audit command response, allowing the MGC to understand and apply both base and extended packages correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the MG publishes only the extended package without the base package, then the package extension capability is improved, but the MGC cannot apply the base package creating a control contradiction
Solution Approach 1:
The patent introduces an audit command as an intermediary mechanism between the MG and MGC. The MG sends an audit command containing the extended package identifier to the MGC, which then retrieves the corresponding base package identifier from its local mapping relationship. This intermediary audit process resolves the contradiction by enabling the MGC to apply the base package even when the MG only publishes the extended package, thus maintaining package application consistency while preserving package extension capability.
2Reliability
If the MG publishes both base and extended packages, then the MGC can apply both packages correctly, but the publishing complexity increases
Solution Approach 1:
The patent extracts the base package identifier from the extended package identifier through the audit command mechanism. Instead of requiring the MG to publish both packages explicitly, the system extracts the base package information on-demand when the MGC receives an extended package identifier. This extraction approach reduces publishing complexity while ensuring the MGC can still apply both base and extended packages correctly for reliable control.
3Adaptability or versatility
If the MGC applies the extended package without knowing the base package relationship, then the service functionality is enhanced, but the control accuracy deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the MG sends an audit command with the extended package identifier to the MGC, and the MGC responds with the corresponding base package identifier based on its local mapping. This feedback loop ensures the MGC has accurate knowledge of the base package relationship when applying packages, maintaining control accuracy while still enabling enhanced service functionality through extended packages.

AI summary
A method, an apparatus, and a system for applying relations between a package base and a package extension are disclosed herein. The method includes: A Media Gateway Controller (MGC) delivers an audit command request to a Media Gateway (MG), where the audit command request carries a package extension information property indicating audit of base-extended relationships of packages supported by the MG; the MGC receives an audit command response returned by the MG, where the audit command response carries the base-extended relationships of the packages supported by the MG; the MGC applies the packages according to the base-extended relationships of the packages supported by the MG; the MG receives a command request delivered by the MGC, where the command request carries a package extension information property whose value is the base-extended relationships of packages supported by the MGC; and the MG applies the packages according to the base-extended relationships of the packages supported by the MGC.
