Dynamic SCCP Addressing for SS7 Inter-Carrier Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SS7 subsystems lack dynamic message addressing capabilities for SMS messages, limiting inter-carrier communication efficiency and billing accuracy across different wireless protocols and carriers.
Innovation Solution
An Intermediary employs dynamic SCCP-level addressing based on configurable rules and data elements to identify and assign 'from' addresses for outgoing SS7 messages, ensuring proper routing and identification of source and destination carriers, and utilizing GTT operations for international carriers like Teleglobe to facilitate accurate billing and branding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static addressing is used in SS7 subsystems, then system simplicity is maintained, but inter-carrier communication efficiency and billing accuracy deteriorate
Solution Approach 1:
The patent implements dynamic message addressing where the source address field in SS7 messages is dynamically populated based on configurable rules and data elements. This allows the addressing system to adapt to different carriers and protocols automatically, improving communication efficiency without requiring manual configuration for each carrier scenario.
Solution Approach 2:
The system changes the parameters of message addresses dynamically by selecting different source addresses from a pool based on carrier-specific rules, message type, and other data elements. This parameter change capability enables accurate routing and billing across multiple carriers while maintaining a unified addressing framework.
2Measurement precision
If carrier-specific addressing rules are implemented, then billing accuracy improves, but system complexity increases
Solution Approach 1:
The system employs self-service mechanisms where the dynamic addressing component automatically selects appropriate source addresses based on pre-configured rules without requiring manual intervention for each message. The rules engine autonomously evaluates message characteristics and carrier requirements to determine the correct addressing format, ensuring billing accuracy while reducing operational complexity.
Solution Approach 2:
The patent introduces an intermediary dynamic addressing component that sits between the message generation system and the SS7 network. This intermediary translates various carrier-specific addressing requirements into standardized SS7 messages, accurately capturing billing information while shielding the rest of the system from carrier-specific complexities.
3Manufacturing precision
If dynamic SCCP-level addressing is implemented, then routing precision improves, but processing complexity increases
Solution Approach 1:
The system performs preliminary action by pre-configuring addressing rules and data element mappings for different carriers before actual message routing occurs. This advance preparation enables the dynamic addressing component to quickly select appropriate addresses during message processing without complex real-time calculations, improving routing precision while managing processing complexity through upfront configuration.
Data Source
AI summary
A method for dynamically modifying the “from” address in SCCP-level address in an SS7 message. An inter-carrier vendor (ICV) or intermediary prearranges with a domestic carrier and an inter-network network (e.g., Teleglobe) to replace the ICV's predetermined static “from” SCCP-level address with a different “from” SCCP-level address. The different address might be selectively or dynamically employed based on an identity of a source wireless carrier, an identity of a destination wireless carrier, a directory number of a source mobile station, or a directory number o f a destination mobile station. The different address may also be used to indicate branding or the fact that a carrier has merged or has acquired another carrier.
