BICC SIP Router ENUM Translation Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for methods and systems to facilitate the integration of Bearer Independent Call Control (BICC) and Session Initiation Protocol (SIP) signaling by providing ENUM translation at a router, enabling communication between BICC, SIP, and legacy nodes.
Innovation Solution
A system and method that includes an ENUM database and a signaling router, which receives a BICC signaling message, obtains a SIP address from the database, generates a SIP signaling message, and routes it to a destination SIP node, allowing for ENUM translation between non-SIP identifiers and SIP identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ENUM translation is implemented at a BICC/SIP router to enable communication between BICC and SIP nodes, then interoperability and adaptability between different signaling protocols is improved, but device complexity increases due to the need for protocol translation functionality
Solution Approach 1:
The patent implements an ENUM translation function within the BICC/SIP router that acts as an intermediary mechanism. This translation function converts E.164 telephone numbers into SIP URIs, enabling BICC nodes to communicate with SIP nodes through the router without requiring direct protocol compatibility between the nodes themselves. The router mediates the communication by translating between the legacy BICC signaling format and the modern SIP format.
Solution Approach 2:
The BICC/SIP router is designed with multi-functionality to handle both BICC and SIP signaling protocols simultaneously. It can receive BICC messages, perform ENUM translation, generate SIP messages, and route them appropriately. This universal capability allows a single router to serve multiple protocol domains, improving adaptability while consolidating functionality rather than requiring separate dedicated devices for each protocol.
2Adaptability or versatility
If protocol translation functionality is added to existing routers, then integration capability between legacy and modern networks is improved, but ease of manufacture and deployment deteriorates due to increased system complexity
Solution Approach 1:
The patent combines the ENUM translation function with the existing BICC/SIP router infrastructure rather than implementing it as a separate standalone system. The translation functionality is integrated into the router's existing message processing, routing, and database query mechanisms. This merging approach allows legacy routers to gain translation capability through software updates or module additions, simplifying deployment compared to implementing separate translation appliances.

AI summary
The subject matter described herein includes methods, systems and computer readable media for providing E.164 number mapping (ENUM) translation at a bearer independent call control (BICC) and/or session initiation protocol (SIP) router. One aspect of the subject matter described herein includes a system for providing ENUM translation. The system includes an ENUM database. The system also includes a signaling router for receiving a bearer independent call control (BICC) signaling message that includes a first call party identifier, for obtaining, from the ENUM database, a first SIP address associated with the first call party identifier, for generating a first SIP signaling message that includes the first SIP address, and for routing the first SIP signaling message to a destination SIP node.
