SMPP Message Conversion for First Delivery Attempt Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SMS communication networks face significant workload burdens due to the inability to apply first delivery attempt (FDA) services to short message peer-to-peer (SMPP) messages originating from external networks, as these services are currently limited to mobile originated SMS messages, leaving SMSCs overloaded with messages from external networks.
Innovation Solution
Converting SMPP messages into mobile originated SMS messages within the network, allowing them to be processed by a first delivery attempt device, which then converts them into mobile terminated SMS messages for immediate delivery, thereby bypassing the SMSC and reducing network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SMPP messages from external networks are processed by the SMSC using traditional store and forward service, then message delivery reliability is maintained, but the SMSC workload increases significantly
Solution Approach 1:
The patent segments the message processing function by introducing a separate FDA device that handles immediate delivery of SMPP messages, while the SMSC retains responsibility for store and forward services. This segmentation allows the SMSC to offload immediate delivery tasks, reducing its workload while maintaining reliable message delivery through the specialized FDA device.
2Speed
If FDA service is applied to mobile originated SMS messages, then immediate delivery is achieved and SMSC is bypassed, but FDA service cannot be applied to SMPP messages from external networks
Solution Approach 1:
The patent introduces an intermediary conversion mechanism that translates SMPP messages from external networks into mobile originated SMS message format. This intermediary conversion layer enables the existing FDA service, which was designed for mobile originated messages, to process SMPP messages by converting them into a compatible format, thus achieving immediate delivery for both message types.
3Reliability
If SMSC processes all SMS messages including those from external networks, then comprehensive message handling is ensured, but network efficiency decreases due to SMSC overload
Solution Approach 1:
The patent extracts the immediate delivery function for SMPP messages from the SMSC and assigns it to a dedicated FDA device. This extraction allows the SMSC to focus on its core store and forward responsibilities while the FDA device handles immediate delivery tasks, improving overall network efficiency by distributing the workload according to each component's strengths.

AI summary
Methods, systems, and computer readable media for providing a first delivery attempt (FDA) for short message peer-to-peer messages are disclosed. One method includes receiving, in a first network, a short message peer-to-peer protocol (SMPP) message from second communications network external to the first communications network. The SMPP message is converted into a mobile originated SMS message. The method also includes forwarding the mobile originated SMS message to a first delivery attempt (FDA) device, wherein the FDA device converts the mobile originated SMS message into a mobile terminated SMS message. The mobile terminated SMS message is delivered to a device in the local communications network.
