Secure SMS Messaging for Mobile Vehicle Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SMS messaging technologies face challenges in efficiently transmitting proprietary data parcels (PDPs) between wireless devices or a mobile device and a server, particularly when the data quantity exceeds the 140-byte limit, leading to inefficiencies in communication and potential security vulnerabilities.
Innovation Solution
A method is introduced to configure and transmit secure SMS messages by determining the data quantity of PDPs, splitting them into multiple SMS messages if necessary, and using an encrypted payload with a message index and internal header to maintain sequence and security, ensuring efficient and secure data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple SMS messages are used to transmit proprietary data parcels, then the data transmission capacity exceeds the 140-byte limit, but the message complexity and sequencing requirements increase
Solution Approach 1:
The patent segments proprietary data parcels into multiple SMS messages when the total data exceeds the 140-byte limit. Each SMS message contains a portion of the PDP data, allowing the system to transmit larger quantities of data by dividing it into manageable segments that fit within standard SMS constraints.
Solution Approach 2:
The patent applies preliminary action by configuring message indexing and sequence numbers before transmission. The sender device assigns sequence identifiers to each segmented SMS message in advance, ensuring proper reassembly order at the receiver. This pre-configuration simplifies the overall process by establishing the framework for handling multiple messages before the actual data transmission begins.
2Reliability
If encrypted payloads are used to secure SMS messages, then data security is improved, but the processing overhead and configuration complexity increase
Solution Approach 1:
The patent merges multiple functions into a single encrypted payload structure. The payload simultaneously carries proprietary data parcel content, sequence numbering information, and encryption credentials. This consolidation reduces the need for separate configuration steps and simplifies the overall encryption process while maintaining security.
3Reliability
If message indexing is implemented to maintain sequence order, then data integrity is improved, but the header size and message overhead increase
Solution Approach 1:
The patent applies partial action by implementing streamlined message indexing that includes only the essential sequence number and total message count in each header. Rather than incorporating comprehensive metadata, the system uses minimal indexing information sufficient to ensure proper reassembly of segmented messages, thereby reducing header overhead while maintaining data integrity.

AI summary
A mobile vehicle communications system and a method of sending one or more secure short message service (SMS) messages using that system. The method includes the steps of: (a) determining at a sender a data quantity associated with zero or more proprietary data parcels (PDPs) to send within one or more SMS messages; (b) configuring an encrypted payload of each of the one or more configured SMS messages to carry the total number of PDPs, wherein when the size of the payload would result in an SMS message exceeding 140 bytes, the configuring step includes configuring a plurality of SMS messages to carry the payload; and (c) transmitting from the mobile originated device one or more configured SMS messages.
