Paging Indication Feedback for Multi-SIM Base Station Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-card terminals, communication conflicts between SIM cards can lead to unnecessary paging by one base station, causing resource waste due to mistaken determination of paging issues.
Innovation Solution
Implementing methods and apparatuses for base stations and terminals to exchange indication information to manage paging conflicts, including sending and receiving indication information to suspend or adjust communications based on SIM card status and service priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal does not respond to the paging from the second base station to keep the communication between SIM card #1 and base station A uninterrupted, then the communication between SIM card #1 and base station A is maintained, but the base station B mistakenly determines that there is a problem with the paging and continues paging the SIM card #2, resulting in resource waste
Solution Approach 1:
The patent introduces a feedback mechanism where the terminal sends indication information to the base station to notify that it has received the paging signal but chooses not to respond due to ongoing communication with another base station. This feedback loop allows the base station to understand the terminal's intent and suspend unnecessary paging operations, resolving the contradiction between maintaining communication continuity and avoiding resource waste.
Solution Approach 2:
The indication information acts as an intermediary message between the terminal and the base station. Instead of the terminal directly controlling the base station's paging behavior, the terminal uses this intermediary indication information to convey its paging reception status and non-response reason, enabling the base station to make informed decisions about resource allocation.
2Loss of information
If the terminal responds to the paging from the second base station, then the base station B can correctly track the paging status, but the communication between SIM card #1 and base station A may be interrupted
Solution Approach 1:
The patent implements dynamic paging control where the base station adjusts its paging behavior based on real-time terminal status information. The system transitions from static paging (continuous or fixed-interval) to dynamic paging (suspend upon receiving indication information), allowing flexible adaptation to the terminal's current communication state and resolving the contradiction between information accuracy and communication continuity.
3Reliability
If the base station continues paging the terminal without receiving response, then the base station can ensure the terminal receives important notifications, but the base station wastes resources on unnecessary paging operations
Solution Approach 1:
The indication information serves as feedback that informs the base station the terminal has received the paging signal. This feedback mechanism allows the base station to distinguish between two scenarios: the terminal intentionally choosing not to respond (due to ongoing communication) versus the terminal failing to respond (indicating a problem). This resolves the contradiction by enabling the base station to suspend paging efficiently while maintaining delivery assurance through the feedback loop.

AI summary
An indication method performed by a first base station includes: sending first indication information to a second base station. The first indication information is configured to indicate that a terminal paged by the second base station has received a paging from the second base station, but the terminal does not respond to the paging.
