Media Gateway Controller Resource Allocation for VoIP Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media resource deployment in IP contact centers results in complex structures, high maintenance costs, and inability to share resources across areas, leading to inefficient load balancing and increased equipment redundancy.
Innovation Solution
A media resource adaptation method where a media gateway controller and a computer telephony integration server are centralized, allowing for area-specific resource allocation based on user terminal location, enabling flexible resource usage and reducing the need for long-distance VoIP links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media resource and service system are deployed together in each dispersed area, then local service functionality is achieved, but deployment structure becomes complex and maintenance cost increases
Solution Approach 1:
The system is segmented into centralized service system (CTI/MGC) and distributed media resources. The service system is separated from media resources, with the service system deployed centrally and media resources distributed in various areas. This segmentation allows local media service functionality while simplifying the overall deployment structure and reducing maintenance complexity.
Solution Approach 2:
The MGC acts as an intermediary between the centralized service system and distributed media resources. It receives service requests, determines the location of calling party terminals, and allocates appropriate media resources. This intermediary mechanism enables centralized control while maintaining distributed resource access, simplifying deployment and maintenance.
2Productivity
If service system and media resource are bound for deployment together, then local processing is enabled, but system maintenance cost increases
Solution Approach 1:
The system separates the service system (CTI/MGC) from media resources, allowing media resources to be independently deployed and maintained in different locations while the service system remains centralized. This segmentation reduces maintenance costs by allowing specialized maintenance of media resources without affecting the service system.
Solution Approach 2:
The centralized service system can serve multiple dispersed areas through the MGC's intelligent resource allocation. A single service system instance can manage media resources across multiple locations, providing universal service capability that reduces the need for multiple redundant service system deployments and lowers maintenance costs.
3Device complexity
If ports of media resource and call repeaters have one-to-one relation, then resource allocation is simplified, but resource sharing across areas is prevented
Solution Approach 1:
The MGC dynamically allocates media resources based on real-time call requirements and terminal locations. Instead of fixed one-to-one binding, the system allows flexible many-to-many relationships where a single media resource can serve multiple call repeaters and areas. This dynamic allocation maintains simple resource management while enabling cross-area resource sharing and load balancing.
4Reliability
If area media resource cannot be shared, then local resource control is maintained, but equipment redundancy increases and cost rises
Solution Approach 1:
Media resources are designed to be universally accessible across multiple areas through the MGC's intelligent routing. A media resource in one area can be allocated to serve calls from other areas when needed, eliminating the need for redundant media resources in each location while maintaining local control capabilities through the MGC's area-based allocation logic.
Solution Approach 2:
The system creates virtual copies of media resource access across areas through the MGC's resource allocation mechanism. Instead of physical redundancy, the MGC manages logical access to shared media resources, allowing multiple areas to access the same physical resources without requiring duplicate hardware installations, thereby reducing equipment redundancy and costs.

AI summary
The embodiment of the invention provides a media resource adaptation method, a media gateway controller and a server. In an embodiment of the invention, the services, the CTIS and the MGC are deployed in the center, each dispersed area is only equipped with the access equipment or the resource equipment, the deployment structure is simple, and the maintenance workload is less. The CTIS decides the resource adaptation, and the resource can be extended to the service sides. Therefore, the resource usage is flexible. The user terminal call can obtain the local media services, which reduces the occupancy of a VoIP long-distance link, thus lowering the operation cost. Furthermore, the global share of the media resources is realized, which is favorable for load balance and reduces the cost of redundancy devices.
