Media Gateway Termination Grouping via Wildcard Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing and grouping terminations in media gateways and media gateway controllers are not efficient, particularly in scalable and multi-vendor environments, as they require excessive signaling and are not flexible, leading to issues with prioritization, termination handling, and compatibility with older systems.
Innovation Solution
The introduction of grouping parameters allows for the classification and grouping of terminations without altering the termination identifier structure, enabling a single command to address multiple terminations based on predefined criteria, such as priority, service type, or interface type, using Boolean logic and a centralized database for policy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminations are released one by one by sending subtract command to each termination, then each termination can be released individually, but the signaling amount and recovery time become unacceptable
Solution Approach 1:
The patent combines multiple individual termination release operations into a single batch operation. Instead of sending separate subtract commands to each termination, the system uses a single subtract command with a wildcard termination ID that matches multiple terminations, allowing them to be released simultaneously in one signaling transaction.
Solution Approach 2:
The patent introduces a wildcard mechanism that allows a single command to apply to multiple terminations. The wildcard termination ID acts as a universal selector that can match multiple specific terminations, enabling one command to perform multiple release operations that would otherwise require separate commands.
2Loss of time
If a wildcard mechanism is used to address multiple terminations, then signaling is reduced, but the grouping is not flexible and not scalable
Solution Approach 1:
The patent segments the termination identification into two parts: a wildcard portion for flexible matching and a specific portion for precise identification. This allows the system to maintain both the efficiency of wildcard matching and the flexibility of specific matching when needed, resolving the contradiction between signaling efficiency and grouping flexibility.
Solution Approach 2:
The patent makes the termination matching mechanism dynamic by allowing the system to switch between wildcard-based batch operations and specific-based operations depending on the situation. The system can dynamically adjust its behavior to balance between signaling efficiency and grouping flexibility based on the specific operational requirements.
3Measurement precision
If proprietary logic is introduced in server node and media gateway for server identification, then server identification is achieved, but multi-vendor environment compatibility is compromised
Solution Approach 1:
The patent creates a universal server identification mechanism that works across different vendors by using standardized wildcard patterns and termination ID formats. Instead of vendor-specific proprietary logic, the system uses a universal approach where any media gateway can interpret the same wildcard commands, ensuring multi-vendor compatibility while maintaining precise server identification capability.
4Adaptability or versatility
If termination identifier structure is changed to support new grouping methods, then grouping flexibility is improved, but backwards incompatibility and upgrade problems occur
Solution Approach 1:
The patent embeds the new grouping functionality within the existing termination identifier structure rather than replacing it. The wildcard mechanism and grouping parameters are nested inside the standard H.248 protocol framework, allowing older systems to continue working while new systems can utilize the enhanced grouping capabilities without requiring fundamental structure changes.

AI summary
Method for grouping terminations of a media gateway by a grouping parameter. When a command containing a grouping parameter is received, the command is executed for a termination if the grouping parameter contained in the received command corresponds to the grouping parameter stored in connection with said termination.
