Multi-SIM Paging Collision Resolution Through Network Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM-card user equipment experiences paging collisions due to overlapping paging occasions, leading to failed service establishment and missed paging signaling.
Innovation Solution
User equipment reports paging collision indication information to the network device, which generates and sends resolution information to resolve the collision by adjusting paging occasions or identifiers, ensuring accurate paging reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-SIM-card UE uses standard paging occasion allocation, then device complexity is reduced, but paging collision occurs leading to service establishment failure
Solution Approach 1:
The UE reports paging collision indication information to the network device, creating a feedback loop that enables the network to adjust paging occasions and prevent future collisions, thereby improving service establishment success rate
Solution Approach 2:
The paging occasion allocation is made dynamic through network device adjustment based on reported collisions, allowing the system to adapt to multi-SIM-card scenarios without requiring complex local processing at the UE
2Reliability
If UE implements paging collision detection and reporting, then paging collision resolution is achieved, but device complexity increases
Solution Approach 1:
The UE monitors for paging collisions and reports the indication information to the network device, enabling the network to resolve the collision issue without requiring complex resolution logic at the UE itself
Solution Approach 2:
The network device acts as an intermediary that receives collision indication information and generates resolution information, separating the complexity of collision resolution from the UE's paging processing

AI summary
The paging collision processing method includes: when a user equipment (UE) determines occurrence of a paging collision, reporting paging collision indication information to a network device; after the network device receives the paging collision indication information, acquiring paging collision resolution information and sending the paging collision resolution information to the UE.
