Dual-SIM Paging Configuration for Collision-Free Message Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-SIM card terminals, overlapping paging occasions for different SIM cards result in collisions, leading to failed message reception and increased power consumption.
Innovation Solution
A method and apparatus to configure SIM cards to receive paging messages at distinct or partially distinct paging occasions to avoid collisions, considering service types and communication parameters, and communicate this configuration to network-side devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same paging occasions are used for multiple SIM cards, then the device complexity is reduced, but the reliability of message reception deteriorates due to collisions
Solution Approach 1:
The patent segments the paging occasions for different SIM cards by predicting collisions and configuring distinct paging occasions for each SIM card. The terminal determines paging occasion information for each SIM card separately, dividing the shared paging resource into dedicated time slots to avoid overlaps and ensure reliable message reception for each SIM card independently.
2Reliability
If distinct paging occasions are configured for each SIM card, then the message reception reliability is improved, but the device complexity increases
Solution Approach 1:
The terminal performs self-configuration by predicting paging occasion collisions internally and automatically determining appropriate paging occasion information for each SIM card. The terminal monitors its own paging occasions, predicts potential collisions, and configures distinct paging occasions without requiring network-side intervention, thereby reducing overall system complexity while maintaining reliability.
3Use of energy by moving object
If paging occasions are optimized based on service types, then the power consumption is reduced, but the complexity of determining paging occasions increases
Solution Approach 1:
The patent applies parameter changes by considering service types and communication parameters when determining paging occasions. The terminal adjusts paging occasion selection based on the specific service requirements (e.g., voice, data, messaging) and communication parameters to optimize power consumption. This targeted approach allows the terminal to sleep longer between paging checks while maintaining service quality, reducing overall power consumption without excessive complexity.
Data Source
AI summary
A paging configuration method, an electronic device, and a computer readable storage medium are provided. The paging configuration method is performed by a terminal, where at least a first SIM card and a second SIM card are arranged in the terminal. The method includes: in response to predicting collisions between paging occasions for the first SIM card to receive a paging message and paging occasions for the second SIM card to receive a paging message, configuring the first SIM card to receive the paging message at first paging occasions of collided paging occasions, and/or configuring the second SIM card to receive the paging message at second paging occasions of the collided paging occasions.
