Mobile Switching Center Server ENUM Query Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face complexity in establishing compatibility between distinct communication protocols, making it challenging to route calls between different subsystems effectively.
Innovation Solution
A mobile switching center server is used to route traffic between subsystems by performing ENUM queries to obtain IP addresses for IMS networks, and if unsuccessful, routing calls through non-IMS networks, while monitoring and prioritizing call routing decisions for efficient migration to IMS systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile switching center server performs ENUM queries to route calls between different communication subsystems, then compatibility between distinct communication protocols is improved, but device complexity increases due to the need to handle multiple protocols and routing decisions
Solution Approach 1:
The mobile switching center server acts as an intermediary between circuit-switched and packet-switched networks. It performs ENUM queries to resolve telephone numbers to IP addresses, enabling seamless call routing between different protocol domains without requiring end devices to handle protocol conversion complexity
Solution Approach 2:
The mobile switching center server is designed to handle multiple communication protocols simultaneously (circuit-switched and packet-switched). It can route calls through IMS networks when ENUM queries succeed, and through non-IMS networks when they fail, making the system universally compatible with different communication standards
2Productivity
If the system routes calls through IMS networks using ENUM queries, then call routing efficiency is improved, but reliability decreases when ENUM queries fail to obtain IP addresses
Solution Approach 1:
The system prepares alternative routing paths in advance. When ENUM queries fail to resolve telephone numbers to IP addresses, the mobile switching center server automatically routes calls through non-IMS networks, ensuring call completion without service interruption. This backup mechanism cushions against ENUM query failures
Solution Approach 2:
The call routing mechanism is dynamic and adaptive. The system monitors ENUM query results in real-time and switches routing paths based on success or failure. When ENUM queries succeed, calls are routed through IMS networks for efficient handling; when they fail, the system dynamically switches to non-IMS network routing
3Productivity
If the system monitors and prioritizes call routing decisions for IMS migration, then migration efficiency is improved, but loss of time increases due to additional monitoring and prioritization processes
Solution Approach 1:
The mobile switching center server automatically monitors call routing decisions and generates statistics without requiring external intervention. It self-manages the prioritization of candidate end user devices for IMS network migration based on observed routing patterns, eliminating the need for manual configuration or external management systems

AI summary
A system that incorporates teachings of the present disclosure may include, for example, receiving a request for a voice call at a mobile switching center server, transmitting a mapping query from the mobile switching center server to a database in response to the request for the voice call, route the request from the mobile switching center server to an internet protocol multimedia subsystem for facilitating establishing the voice call when the mapping query is successful in obtaining an internet protocol address for establishing the voice call with a recipient communication device, and routing the request from the mobile switching center server to a second server for facilitating establishing the voice call without routing the request to the internet protocol multimedia subsystem when the mapping query is not successful in obtaining the internet protocol address. Other embodiments are disclosed.
