Broadcast Notification Message Parsing for Mobile Alert Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcasting systems lack a standardized method for efficiently transmitting and receiving notification messages, particularly in portable broadcast services, which hinders the delivery of timely content changes, public notices, and emergency alerts to mobile terminals.
Innovation Solution
An apparatus and method for generating and transmitting notification messages in a broadcasting system, including a Notification Event Function, a Notification Generation Function, and a Notification Distribution/Adaptation Function, which create and distribute notification messages with specific attributes like NotificationType, PresentationType, and FilteringValue to ensure appropriate handling and display on mobile terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If notification messages are transmitted without standardized formats, then system flexibility is maintained, but message handling efficiency and reliability deteriorate
Solution Approach 1:
The notification message is segmented into distinct standardized fields including message type identifier, priority level, timestamp, source identifier, and content payload. This segmentation allows efficient parsing and processing by mobile terminals while maintaining systematic organization, resolving the contradiction between handling efficiency and standardization complexity.
Solution Approach 2:
A universal notification message format is designed that can accommodate multiple types of notifications (service guide updates, content changes, emergency alerts, public notices) through a single standardized structure. This multi-functional approach improves handling efficiency across different notification types without requiring separate complex protocols for each type.
2Loss of information
If notification messages include detailed content information, then user information needs are met, but transmission overhead and network bandwidth consumption increase
Solution Approach 1:
The notification message extracts and transmits only essential information elements such as message type, priority, timestamp, and key content identifiers, while detailed content can be retrieved separately from content servers. This extraction approach ensures critical information is delivered efficiently without excessive bandwidth consumption, while maintaining content completeness through on-demand retrieval.
Solution Approach 2:
Content identifiers and metadata are transmitted in advance in the notification message, allowing mobile terminals to prepare for content retrieval before actual content delivery. This preliminary action enables efficient bandwidth utilization by transmitting only essential routing and identification information upfront, with full content delivered only when needed and resources are available.
3Loss of time
If notification messages are transmitted frequently to ensure timely delivery, then information timeliness is improved, but network traffic load and terminal processing burden increase
Solution Approach 1:
The system implements periodic notification checks where mobile terminals poll for notifications at predetermined intervals rather than receiving continuous streams. This periodic approach maintains timely delivery of important information while significantly reducing overall network traffic volume and terminal processing burden compared to continuous transmission schemes.
Solution Approach 2:
The notification system incorporates acknowledgment and status feedback mechanisms where terminals confirm receipt and processing state of notifications. This feedback allows the network to intelligently adjust transmission frequency based on actual terminal status, delivering timely notifications when needed while reducing unnecessary traffic when terminals are already up-to-date or unable to process additional messages.
Data Source
AI summary
A terminal apparatus is provided for receiving a broadcast service from a broadcasting system. A receiver receives a notification message from the broadcasting system. A message parser parses the notification message received by the receiver according to a certain format. A controller determines whether the received notification message is a notification message to be used by a user or a notification message to be used by the terminal based on content of the notification message parsed by the message parser, and performs an operation according to the determination result.
