Roaming Multimedia Message Server Pull Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia message transmission using roaming services often results in high data roaming costs and unsolicited message reception due to the push method, where messages are sent without user acknowledgment.
Innovation Solution
Implementing a pull method where the multimedia message server determines the roaming state of the receiver and sends a notification message for user acceptance before transmitting the message, using a system comprising a home location register, multimedia message server, and short message server to manage the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the push method is used to transmit multimedia messages to roaming users, then message delivery speed is improved, but user control over message reception deteriorates and data roaming costs increase
Solution Approach 1:
The system dynamically switches between push method (for non-roaming users) and pull method (for roaming users) based on the user's roaming status. This dynamic adaptation allows the system to maintain fast message delivery for local users while providing user control and cost management for roaming users.
Solution Approach 2:
The transmission method parameter is changed based on the user's location status. When a user is detected to be roaming, the system changes from automatic push transmission to pull transmission requiring user acknowledgment, thereby controlling data usage and costs while maintaining user control.
2Extent of automation
If the push method is used for multimedia message transmission, then automated message delivery is improved, but data roaming costs deteriorate due to unintended downloads
Solution Approach 1:
The system performs preliminary action by checking the user's roaming status before transmitting the multimedia message. This preliminary check allows the system to select the appropriate transmission method (push or pull) in advance, preventing unintended data downloads and associated costs.
Solution Approach 2:
The system uses feedback from the user's response to the notification message to determine whether to proceed with message transmission. For roaming users, the message is only transmitted after receiving user acknowledgment, providing feedback-based control to prevent unnecessary data consumption and costs.
3Loss of energy
If location information checking is added to determine roaming state, then user cost management is improved, but system complexity deteriorates
Solution Approach 1:
The system uses an intermediary (location information management system) to handle the complex task of determining user roaming status. This intermediary component simplifies the overall system architecture by centralizing location-based decision-making logic.

AI summary
The present invention relates to a system for transmitting a multimedia message to a roamed multimedia message receiver, and a method thereof. In the method, when the multimedia message is transmitted from a first mobile communication network to a multimedia message receiver that has roamed from the first mobile communication network to a second mobile communication network, location information of the multimedia message receiver is determined according to a request for transmission of the multimedia message. A roaming state of the multimedia message is determined based on the location information of the multimedia message receiver When it is determined that the multimedia message receiver has roamed, a notification message of a pull method is transmitted to the multimedia message receiver to determine whether the multimedia message receiver accepts receipt of the multimedia message. In addition, when a response of acceptance is received from the multimedia message receiver, the multimedia message is transmitted to the multimedia message receiver.
