A2P Message Differentiation via Parameter Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to differentiate between application-to-person (A2P) SMS messages and person-to-person (P2P) SMS messages, leading to incorrect filtering and resource wastage, as A2P messages often resemble spam and lack distinct identifiers.
Innovation Solution
A device, such as a server, determines whether an A2P message is from a third-party messaging server and configures a parameter to identify it as a specific type of message, allowing other devices to differentiate and filter A2P messages accurately, thereby improving filtering efficiency and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If A2P messages are filtered using existing systems, then spam filtering may be applied, but A2P messages are erroneously filtered and lost
Solution Approach 1:
The patent applies preliminary action by inserting a distinctive identifier (such as a header field or metadata tag) into A2P messages before they are transmitted through the network. This pre-marking allows receiving systems to immediately recognize and differentiate A2P messages from spam, preventing erroneous filtering while maintaining reliable delivery of legitimate application messages.
2Measurement precision
If content-based filtering rules are used to differentiate A2P messages, then filtering accuracy may improve, but computing resources and time are consumed
Solution Approach 1:
The patent extracts the differentiation function from complex content-based analysis by isolating a specific, easily identifiable parameter (such as a header field or metadata element) that uniquely identifies A2P messages. This extraction allows systems to differentiate message types through simple parameter checking rather than resource-intensive content analysis, significantly reducing computing time while maintaining high differentiation accuracy.
Solution Approach 2:
The patent changes the parameter used for message differentiation from analyzing message content characteristics to checking a specific identifier parameter (such as a header field value or metadata tag). This parameter change transforms the differentiation process from a computationally expensive content-based analysis to a simple parameter comparison, reducing both computing time and resource consumption while maintaining accurate message type identification.
3Device complexity
If no distinct identifier is used for A2P messages, then message format simplicity is maintained, but A2P messages cannot be differentiated from P2P or spam messages
Solution Approach 1:
The patent introduces an intermediary element (a distinctive identifier such as a header field or metadata tag) that acts as a mediator between the simple message structure and the need for message type differentiation. This intermediary carries the necessary identification information without fundamentally altering the core message structure, allowing A2P messages to be differentiated from P2P and spam messages while maintaining overall structural simplicity.
Data Source
AI summary
A device may receive a message from a third party messaging server device. The message may be destined for one or more user devices. The message may include a parameter that includes information related to the message. The device may determine that the message is an application-to-person (“A2P”) message type based on the message being received from the third party messaging server device. The device may configure a value of the parameter based on determining that the message is the A2P message type. The device may provide the message to a user device, of the one or more user devices, or an inter-carrier server device after configuring the value of the parameter.
