Solution Overview

Problem

Current messaging systems in public land mobile networks waste resources and incur unnecessary charges when pre-pay subscribers attempt to send multimedia messages without sufficient credit, as the entire message is transmitted to the multimedia messaging service center before credit verification, leading to dropped messages and repeated attempts.

Innovation Solution

Implementing a method where the network determines authorization for message transmission based on the subscriber's credit level before allowing the message content to be sent, using a pre-dialogue to transfer only relevant message properties and prevent unnecessary data loading, thereby saving radio resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the entire message is transmitted to the MMSC before credit verification, then the message transmission process is simple, but radio resources are wasted and network resources are burdened

Engineering Contradiction:
Improvemessage transmission processVSAvoidradio resources
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by performing credit verification before the actual message transmission. The MMSC checks the subscriber's credit balance in advance (step 304) and only allows message content transmission if sufficient credit is available. This prevents wasteful transmission of large multimedia messages when the subscriber cannot pay, thereby conserving radio resources while maintaining a simple overall process.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If the entire message is transmitted to the MMSC before credit verification, then the transmission process is straightforward, but messages are dropped and subscribers may repeatedly attempt transmission

Engineering Contradiction:
Improvetransmission processVSAvoidmessage delivery
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent performs credit verification in advance (step 304) before allowing message transmission. This preliminary check ensures that only messages from subscribers with sufficient credit are transmitted, eliminating the problem of dropped messages due to insufficient funds. The subscriber receives clear feedback about credit status before attempting transmission, improving reliability and preventing repeated futile attempts.

Inventive Principle:
Principle #10Preliminary action

3Speed

If credit verification is performed after message transmission, then the message can be sent immediately, but resources are wasted if the subscriber lacks sufficient credit

Engineering Contradiction:
Improvemessage transmission speedVSAvoidnetwork resources
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

The patent reverses the conventional order by performing credit verification (step 304) before message transmission instead of after. The MMSC checks the subscriber's credit balance first, and only if sufficient credit is available does it proceed to receive and transmit the message content. This ensures that network resources are not wasted on messages that cannot be paid for, while still allowing immediate transmission when credit is sufficient.

Inventive Principle:
Principle #10Preliminary action

AI summary

A communication system providing messaging services can have a receiving unit configured to receive a request to send a message, an authorization unit configured to authorize the sending of the message in response to the request, and a transmitting unit configured to transmit the authorization to send the message.
