Media Gateway Internal Connection Control via Capability Auditing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media gateway technologies lack standardized means for determining and controlling internal connections, leading to inefficiencies and compatibility issues between Media Gateway Controllers (MGC) and Media Gateways (MG) from different vendors, especially when implementing internal connections.
Innovation Solution
A method and apparatus for implementing internal connections at a media gateway, where the MGC acquires information on the MG's capability for supporting internal connections and performs corresponding control, allowing for adaptive implementation of internal connections by either the MGC or the MG itself, enabling direct connection of call parties within the same media gateway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the MGC determines and controls internal connections, then compatibility and standardization are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent enables the media gateway to autonomously determine and control internal connections by auditing its own capability and making connection decisions locally, eliminating the need for MGC intervention in internal connection management, thus reducing MGC processing overhead while maintaining compatibility through standardized capability auditing
Solution Approach 2:
The patent segments the connection control function into two parts: external connections controlled by MGC and internal connections controlled autonomously by the media gateway, allowing each component to handle only the connections it is responsible for, reducing overall system complexity
2Productivity
If the media gateway autonomously determines internal connections, then processing efficiency is improved, but adaptability to different service requirements deteriorates
Solution Approach 1:
The patent introduces dynamic capability auditing where the media gateway can adapt its connection determination behavior based on service characteristics, enabling or disabling autonomous internal connection capability through standardization parameters to balance efficiency and adaptability
Solution Approach 2:
The patent uses parameter changes in capability auditing to allow the media gateway to switch between autonomous and MGC-controlled connection determination modes, enabling flexible adaptation to different service requirements while maintaining processing efficiency
3Device complexity
If internal connections are implemented without capability auditing, then device complexity is reduced, but reliability and compatibility deteriorate
Solution Approach 1:
The patent implements preliminary capability auditing before internal connection determination, where the media gateway audits its own capability in advance and stores the result, ensuring compatibility and reliability are maintained without adding significant system complexity

AI summary
A method and apparatus to implement media gateway internal connection. The MGC obtains the MG's capability of supporting an internal connection via audit or configuration. Based on the obtained capability, the MGC determines and controls the implementation of the internal connection, or the MG determines and controls the implementation of the internal connection itself. If the MG determines and controls the implementation of the internal connection itself, the MG informs the MGC to modify the call mode in the MGC into the same as in the MG, or maps between the respective operations for the MGC and the MG after the MG implements the internal connection. The MGC and the MG with different connecting capability can cooperate with each other and achive the benefit from the internal connection to the furthest extent. The MGC can also control the MG's capability of determining and realizing the internal connection based on the service characteristics.
