Selective Cell Broadcast Reception via Self-Learning Policy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enabling the Cell Broadcast Service (CBS) function on terminal devices increases power consumption, negatively impacting standby time, and traditional UI-based enable/disable methods are complex and inefficient.
Innovation Solution
A terminal device determines attributes of received CBS messages through a self-learning process to establish a policy for receiving further messages, reducing unnecessary power consumption by selectively omitting non-essential messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the CBS function is enabled on the terminal device to receive CBS messages, then the device can receive emergency and important broadcast information, but the power consumption increases significantly
Solution Approach 1:
The terminal device automatically determines attributes of CBS messages and generates reception policies without user intervention. The device self-learns from message attributes (emergency type, importance level, frequency) and autonomously decides which messages to receive, eliminating the need for manual UI configuration while optimizing power consumption.
Solution Approach 2:
The CBS reception policy is dynamically adjusted based on message attributes rather than being static. The terminal device continuously evaluates incoming messages, determines their attributes, and adapts the reception policy in real-time, allowing the system to be more selective about which messages to receive, thereby reducing overall power consumption.
2Reliability
If the CBS function is enabled continuously to ensure receipt of all CBS messages, then no important messages are missed, but the standby time of the terminal device decreases
Solution Approach 1:
The terminal device autonomously manages CBS message reception by automatically determining message attributes and generating reception policies. This self-service mechanism ensures important messages are not missed while avoiding unnecessary reception of non-critical messages, thereby extending standby time without compromising reception completeness.
Solution Approach 2:
Instead of continuously receiving all CBS messages, the terminal device applies partial action by selectively receiving only those messages that meet specific attribute criteria (e.g., emergency type, high importance). This partial reception strategy maintains reliability for critical messages while significantly reducing power consumption and extending standby time.
3Loss of information
If the terminal device receives all CBS messages without selection, then all broadcast information is captured, but unnecessary power is consumed on non-essential messages
Solution Approach 1:
The terminal device automatically analyzes message attributes and generates reception policies without user intervention. This self-service approach ensures that all essential information is captured by evaluating message importance, while automatically filtering out non-essential messages to prevent energy waste.
Solution Approach 2:
Different reception strategies are applied to different types of CBS messages based on their local attributes. Emergency messages receive high-priority processing, while non-essential messages are filtered or processed with lower priority. This localized quality approach ensures information completeness for critical messages while reducing energy consumption on non-essential content.
4Ease of operation
If traditional UI-based enable/disable methods are used for CBS function, then users can control message reception, but the operation becomes complex and inefficient
Solution Approach 1:
The terminal device automatically determines message attributes and generates reception policies without requiring user configuration. This eliminates the complex UI-based enable/disable methods while maintaining user control capability, as the system autonomously makes reception decisions based on message importance and attributes.
Solution Approach 2:
The system continuously monitors message attributes and uses this feedback to dynamically adjust reception policies. By incorporating feedback from message content analysis, the system automatically optimizes reception behavior without requiring manual user intervention, simplifying operation while maintaining effectiveness.

AI summary
According to implementations of the subject matter described herein, a new approach for receiving the CBS message is proposed. Generally speaking, in response to receiving a CBS message from a network device, a terminal device will determine an attribute of the CBS message. Then, the terminal device will determine a policy for receiving a further CBS message based on the determined attribute. That is, the policy is determined through a self-learning process performed on the received CBS message (s). In this way, the power consumption of the terminal device for receiving the CBS messages can be reduced. As a result, the battery life of the terminal device can be guaranteed.
