Paging Non-Response Indication for Multi-SIM Base Station Feedback

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In wireless communication networks, a base station cannot determine whether a terminal fails to respond to a paging message due to its own issues or internal problems with the terminal, leading to unnecessary resource wastage from increased power and frequency of paging attempts.

Innovation Solution

The terminal sends indication information to the base station when it cannot respond to a paging message, specifying the reason for non-response, allowing the base station to differentiate between its own issues and terminal problems, thereby avoiding unnecessary operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the base station increases power and frequency of paging attempts when the terminal does not respond, then the paging reliability is improved, but the energy consumption and resource usage of the base station increase

Engineering Contradiction:

Improvepaging reliabilityVSAvoidbase station energy consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The terminal provides feedback to the base station through indication information to explain why it cannot respond to paging messages. This feedback mechanism allows the base station to understand the terminal's state (e.g., processing other signaling, unable to access random access channel) and avoid unnecessary repeated paging attempts, thereby reducing energy consumption while maintaining paging reliability.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The terminal proactively informs the base station about its inability to respond to paging messages by sending indication information. This self-service approach allows the terminal to manage the paging process autonomously by providing reasons for non-response, enabling the base station to make informed decisions about whether to continue paging attempts.

Inventive Principle:

Principle #25Self-service

2Reliability

If the base station performs repeated paging operations when the terminal does not respond, then the paging completeness is improved, but the communication efficiency deteriorates

Engineering Contradiction:

Improvepaging completenessVSAvoidcommunication efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The indication information sent by the terminal provides feedback about the specific reason for non-response (e.g., processing other signaling, random access channel unavailable). This feedback enables the base station to distinguish between temporary unavailability and genuine paging failures, allowing it to stop unnecessary repeated paging operations and improve communication efficiency while maintaining paging completeness for valid cases.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Instead of the base station blindly repeating paging operations to ensure completeness, the system inverts the approach by having the terminal actively indicate when it cannot respond and why. This inversion shifts the decision-making from base station speculation to terminal-provided information, improving efficiency without sacrificing completeness.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If the base station increases paging frequency to ensure terminal response, then the paging reliability is improved, but the network resource usage increases

Engineering Contradiction:

Improvepaging response rateVSAvoidnetwork resource consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The terminal sends indication information to the base station explaining why it cannot respond to paging messages (e.g., processing other signaling, unable to access random access channel). This feedback allows the base station to stop increasing paging frequency when the terminal is temporarily unavailable, reducing network resource consumption while maintaining high paging response rates for terminalsthat can respond.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The terminal proactively sends indication information before the base station can determine that paging attempts are futile. This preliminary action prevents the base station from wasting network resources on repeated paging operations that will not succeed, thereby reducing overall network resource consumption while maintaining paging reliability.

Inventive Principle:

Principle #10Preliminary action

AI summary

A response indication method, performed by a terminal which is at least provided with a first Subscriber Identity Module card, includes: receiving a paging message through the first SIM card; and sending indication information to a base station that sends the paging message; in which the first SIM card does not respond to the paging message, the indication information indicates to the base station that the first SIM card is not to respond to the paging message. Other reasons for sending the indication information are also discussed.
