ENUM Server Contact Routing via IMS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Provisioning and providing contact services in communication networks is a tedious, time-consuming, and error-prone process due to the complexity of coordinating multiple systems such as PBX, AIN, and SS7 systems.
Innovation Solution
A system and method utilizing an Internet Protocol Multimedia Subsystem (IMS) with a Home Subscriber Server (HSS) and a Telephone Number Mapping (ENUM) server, which manages subscriber records with Uniform Resource Identifiers (URIs) and preference/data values to efficiently route calls to destination devices based on predefined sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods are used to provision contact services involving multiple systems (PBX, AIN, SS7), then contact services can be provided, but the process becomes tedious, time-consuming, and error-prone
Solution Approach 1:
The patent introduces an ENUM server as an intermediary component that mediates between the traditional telephony systems (PBX, AIN, SS7) and the contact service provisioning process. The ENUM server centralizes the management of contact information and routing logic, reducing the coordination complexity across multiple systems while improving reliability by providing a single point of control for contact service provisioning.
2Adaptability or versatility
If multiple systems are coordinated to provide contact services, then comprehensive contact routing is achieved, but the provisioning process becomes time-consuming
Solution Approach 1:
The patent implements preliminary action by pre-configuring contact information and routing rules in the ENUM server before actual contact service provisioning is needed. Contact patterns, destination information, and routing logic are established in advance, allowing the system to quickly provision and route contacts without time-consuming coordination during the actual provisioning process.
3Productivity
If traditional contact service provisioning is used, then services can be provided across multiple systems, but the process is tedious and error-prone
Solution Approach 1:
The patent merges the functions of multiple separate systems (PBX, AIN, SS7 coordination) into a single integrated ENUM server that handles contact service provisioning. By combining these distributed functions into one centralized component, the system improves productivity by eliminating the need for tedious coordination across multiple systems while maintaining the comprehensive routing capabilities.
Data Source
AI summary
A communication system includes an application server including logic to receive preference data for each of a plurality of data record entries of a subscriber record from a telephone number mapping (ENUM) server, and to determine a contact sequence including a plurality of Uniform Resource Identifiers (URIs). The contact sequence is based at least in part on the received preference data.
