Dual-SIM Paging Feedback to Prevent Continuous Network Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-card terminal devices face issues with signaling resource waste and erroneous statistics due to intermittent monitoring of secondary systems, leading to continuous paging attempts by network devices when the terminal does not respond.
Innovation Solution
Implementing a paging processing method where a connected subscriber identity card sends busy indication information to the core network device when a secondary card in an idle state receives a paging message, indicating temporary non-response, thereby notifying the network to suspend paging.

Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-card terminal device intermittently detects a second system while communicating with a first system, then the terminal can maintain dual-card dual-standby capability, but signaling resources are wasted and erroneous statistics occur due to continuous paging attempts when the terminal does not respond
Solution Approach 1:
The terminal device sends feedback information to the network device to indicate whether it can respond to paging messages. This feedback mechanism allows the network to understand the terminal's actual state and adjust paging strategies accordingly, preventing continuous paging attempts when the terminal is busy with the first system and avoiding signaling resource waste.
Solution Approach 2:
The patent introduces an intermediary indication mechanism where the terminal provides state information to the network, which then acts as a mediator to coordinate paging behavior. The network device uses this information to determine whether to send paging messages, effectively mediating between the terminal's dual-card operations and the network's paging requirements.
2Adaptability or versatility
If a multi-card terminal device monitors paging messages from a second system while maintaining communication with a first system, then the terminal can establish services on the second system, but the performance of the first system is impacted
Solution Approach 1:
The terminal device dynamically adjusts its paging monitoring behavior based on its current communication state with the first system. When engaged with the first system, the terminal indicates it cannot respond to paging, and when available, it can respond. This dynamic adjustment allows service establishment on the second system without permanently impacting the performance of the first system.
3Reliability
If a network device continues to page a multi-card terminal device that does not respond to paging messages, then the network can ensure service establishment on the second system, but erroneous statistics and operations occur
Solution Approach 1:
The terminal device provides feedback information to the network device indicating its ability to respond to paging messages. This feedback prevents the network from generating erroneous statistics by giving accurate information about the terminal's state, allowing the network to distinguish between intentional non-response and actual service establishment failures.
Data Source
AI summary
Provided in the present application are a paging processing method and apparatus, and a storage medium. The paging processing method is applied to a multi-card terminal device, and the method includes: in response to that a second subscriber identity card in an idle state in the multi-card terminal device receives a paging message sent from a second network device, sending, by a first subscriber identity card in a connected state in the multi-card terminal device, first busy indication information to a first core network device. The first busy indication information is used to indicate that the multi-card terminal device has received the paging message of the second network device and decided not to respond temporarily.
