Front End Processor SMSC SIP Gateway Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing SMS network architecture is inefficient and vulnerable as it requires interfacing with external SIP gateways to reach SIP-enabled devices, leading to potential performance degradation and dis-intermediation of carriers from end-point subscribers, limiting monetization opportunities.
Innovation Solution
Integration of a Front End Processor (FEP) with the SMSC to provide SIP services and management, enabling direct SIP enablement within the carrier network, thereby bypassing external SIP gateways and enhancing message delivery efficiency and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the SMSC interfaces with external SIP gateways to reach SIP-enabled devices, then message delivery capability is achieved, but performance degradation occurs and carrier control is lost
Solution Approach 1:
The patent merges the SIP gateway functionality directly into the SMSC by integrating a front-end processor that provides both SMSC and SIP gateway functions in a single network element. This eliminates the need for external SIP gateway interfaces while maintaining message delivery capability to SIP-enabled devices, thereby resolving the performance degradation and control loss issues associated with external gateway interfaces
2Adaptability or versatility
If external SIP gateways are used for protocol translation, then SIP device connectivity is enabled, but carrier monetization opportunities are limited due to dis-intermediation
Solution Approach 1:
The patent combines the SIP gateway functions within the carrier-controlled SMSC infrastructure, ensuring that the carrier remains intermediated in the message delivery path. This integration allows the carrier to maintain control over protocol translation and monetization opportunities while still enabling connectivity to SIP-enabled devices
3Adaptability or versatility
If multiple external gateways are traversed for message transmission, then diverse device support is achieved, but message delivery time increases
Solution Approach 1:
The patent integrates multiple protocol handling capabilities (SMS, SIP, and other messaging protocols) within a single SMSC-based network element. This consolidation eliminates the need to traverse multiple external gateways, thereby reducing message delivery time while maintaining support for diverse device types and protocols
4Adaptability or versatility
If protocol translation is performed at external gateways, then multi-protocol support is achieved, but security control is reduced
Solution Approach 1:
The patent consolidates protocol translation functions within the carrier-controlled SMSC infrastructure, maintaining centralized security control. By keeping all protocol translation and message routing functions within the carrier's network boundary, the system maintains security policies and threat response coordination while supporting multiple protocols
