Multi-SIM Paging Indication to Avoid Unnecessary Network Responses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-card terminals face issues with signaling resource waste and incorrect operations due to uncoordinated handling of paging messages across multiple SIM cards, affecting service quality and efficiency.
Innovation Solution
Implement methods and apparatus for a second SIM card to determine whether to respond to a paging message based on target conditions, sending target indication information to the base station, and for the base station to recognize non-response, thereby avoiding unnecessary paging attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second SIM card responds to all paging messages, then the base station can maintain accurate location information and service connectivity, but signaling resources are wasted and service quality deteriorates when the first SIM card is in service
Solution Approach 1:
The patent changes the response parameter of the second SIM card based on the service state of the first SIM card. When the first SIM card is in service, the second SIM card changes its paging response parameter from 'respond' to 'not respond', thereby adapting the system behavior to current service conditions and resolving the contradiction between maintaining connectivity and avoiding resource waste
Solution Approach 2:
The patent introduces dynamic adjustment of paging response behavior. The second SIM card's response to paging messages is no longer static but dynamically changes based on whether the first SIM card is in service. This dynamic mechanism allows the system to optimize resource usage while maintaining service reliability when needed
2Loss of energy
If the second SIM card does not respond to paging messages when the first SIM card is in service, then signaling resources are saved, but the base station performs incorrect operations and statistical analysis becomes inaccurate
Solution Approach 1:
The patent introduces target indication information as an intermediary communication mechanism. When the second SIM card does not respond to paging, it sends target indication information to the base station, which serves as a mediator to convey the 'received but not responding' status. This resolves the information loss problem while maintaining resource efficiency
Solution Approach 2:
The patent implements a feedback mechanism where the second SIM card provides status information to the base station through target indication information. This feedback loop allows the base station to understand why no paging response was received, preventing incorrect operations and maintaining accurate statistical analysis while still saving signaling resources
3Device complexity
If multi-card terminals use non-standardized processing methods, then device complexity is reduced with manufacturer-specific implementations, but service quality and resource utilization deteriorate
Solution Approach 1:
The patent establishes a universal standardized processing method that can be applied to all multi-card terminals regardless of manufacturer. The standardized mechanism for determining whether to respond to paging messages and sending target indication information ensures consistent service quality across different devices while maintaining reasonable complexity through a unified approach

AI summary
Provided in the present disclosure are an information sending method and apparatus, and a storage medium. The information sending method includes: in response to determining that a first SIM card of a multi-card terminal is in service and detecting a paging message for paging the second SIM card that is sent by a second base station, determining whether to respond to a paging, wherein the second base station is a base station where the second SIM card resides; and sending target indication information to the second base station in response to determining not to respond to carry out a paging response, the target indication information being used to inform the second base station that the second SIM card has received the paging message, but not to respond to a paging.
