SMS Contact Update for Automatic MSISDN Change Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no simple and automatic way for users to inform their contacts about a change in their Mobile Station International Subscriber Directory Number (MSISDN) in a telecommunications network, requiring manual notification to each contact.
Innovation Solution
A contact update server in the telecommunications network automatically updates the MSISDN change to trusted contacts by generating SMS messages based on contact information stored in a unified data management system, utilizing a short message service center to deliver these messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual notification to each contact is used, then users can inform contacts about MSISDN changes, but the process requires significant time and effort from users
Solution Approach 1:
The system enables automatic self-service notification where the network infrastructure autonomously contacts trusted users about MSISDN changes without requiring manual intervention from the changing user. The HLR automatically detects MSISDN changes and triggers SMS notifications to pre-configured trusted contacts.
Solution Approach 2:
The patent introduces an intermediary automated notification system comprising the HLR and SMS gateway that mediates between the MSISDN change event and the trusted contacts. This intermediary automatically processes the notification delivery, eliminating the need for direct manual communication from the user to each contact.
2Ease of operation
If automated SMS notification system is implemented, then user burden is reduced, but system complexity increases
Solution Approach 1:
The patent leverages existing multi-functional network infrastructure components (HLR and SMS gateway) that already perform multiple functions in the mobile network. By repurposing these existing components for automated MSISDN change notification, the system avoids adding dedicated new hardware while achieving automated notification capability.
Solution Approach 2:
The system utilizes self-service mechanisms where existing network components automatically perform notification tasks without requiring additional complex control systems. The HLR self-detects MSISDN changes and the SMS gateway self-routes notifications, minimizing the need for elaborate automated management infrastructure.
3Loss of information
If all contacts are notified about MSISDN changes, then complete information dissemination is achieved, but unnecessary notifications increase user burden
Solution Approach 1:
The patent applies local quality by differentiating notification delivery based on the trusted relationship status of each contact. Instead of uniform notification to all contacts, the system selectively notifies only those contacts marked as trusted in the user's profile, providing tailored information delivery matching the local characteristic of each contact relationship.
Solution Approach 2:
The system performs preliminary action by requiring users to pre-configure which contacts should receive MSISDN change notifications before the change occurs. This advance configuration of trusted contacts allows the automated system to immediately identify and notify the correct subset of contacts when a MSISDN change happens, without requiring real-time user decisions.
Data Source
AI summary
The disclosed technology performs an automatic update of a Mobile Station International Subscriber Directory Number (MSISDN) change to at least a subset of contacts associated with a user account. Upon receiving an indication of a MSISDN change associated with an account, a contact update server of a telecommunications network retrieves contact information that includes multiple contacts of the account with multiple identifiers. The contact update server generates short messaging service (SMS) messages to be delivered to the multiple contacts of the account based on the multiple identifiers. The SMS messages include information regarding the MSISDN change associated with the account. The contact update server transfers the SMS messages to a short message service center (SMSC), and the SMSC delivers the SMS messages to the multiple contacts of the account.
