Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If SMS messages are sent simultaneously with audio advertisements, then the advertising information is delivered to subscribers, but the messages become unwanted and can be easily forwarded, reducing advertising effectiveness
Solution Approach 1:
The system sends a confirmation request SMS message to the subscriber's mobile phone before delivering the actual advertising SMS message. The subscriber must confirm receipt of the request message, and only then will the advertising message be delivered. This preliminary action ensures that subscribers actively opt-in to receive advertising messages, preventing unwanted messages and ensuring message authenticity.
2Quantity of substance
If SMS messages are sent to all subscribers listening to audio messages, then advertising reach is maximized, but the value of m-coupons is reduced due to easy forwarding
Solution Approach 1:
The system requires subscribers to confirm receipt of a request message before delivering advertising messages with m-coupons. This ensures that only subscribers who actively opt-in receive the messages, preventing unauthorized forwarding and maintaining coupon value. The confirmation step creates a trusted delivery mechanism that preserves the exclusivity and value of promotional content.
3Speed
If SMS messages are delivered during active calls, then real-time communication is achieved, but the messages become intrusive and打扰 to the subscriber
Solution Approach 1:
The system sends the confirmation request message during the call, but delays delivery of the actual advertising message until after the call ends. The subscriber confirms receipt of the request message during or after the call, and only then is the advertising message delivered. This timing strategy eliminates intrusion during active communication while maintaining real-time interaction capability.

AI summary
A method for transmitting SMS messages to a subscriber GSM telephone after a call is ended and authenticating the source of the delivered text message with a logo or other graphic not forwardable by mobile phone subscribers is provided. In the present invention, audio advertisements are selected based on a mobile phone subscriber's profile, and accompanying SMS messages or m-coupons are further transmitted to the subscriber only upon their request. A check will be carried out on the eligibility of the subscriber to receive the SMS message they had requested for. This check limits the number of times the subscriber receives a same SMS message. If the subscriber is eligible to receive the message, an authenticating symbol is included in the SMS message before transmission so that retransmission to other users will delete the graphic and render the SMS message invalid for business transactions.
