Multi-SIM Terminal Paging Collision Resolution via Dynamic Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In next-generation mobile communication systems, terminals supporting multi-SIM face challenges in preventing paging collisions, which can lead to inefficient communication with the network.
Innovation Solution
A method where a terminal receives first system information from a cell of a first base station, identifies overlapping paging occasions with a second base station, and transmits a message with paging adjustment parameters to the first base station. The base station then determines and transmits adjusted parameters back to the terminal to prevent paging collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal supports multi-SIM and monitors paging occasions from multiple base stations, then the terminal can maintain connectivity with multiple networks, but paging collisions occur when paging occasions overlap
Solution Approach 1:
The patent implements dynamic paging occasion adjustment by allowing the terminal to request and the network to assign adjusted paging occasions dynamically. The terminal monitors overlapping paging occasions, sends a request message with first parameters to the network, and receives adjusted second parameters that dynamically reposition paging occasions to eliminate collisions while maintaining multi-SIM connectivity.
Solution Approach 2:
The patent changes paging occasion parameters (time, frequency, or resource allocation) to resolve collisions. The terminal identifies overlapping paging occasions by comparing parameters from multiple base stations, then requests parameter adjustments. The network responds with modified parameters that reposition paging occasions to non-overlapping time slots or frequency resources.
2Reliability
If paging occasions are adjusted to prevent collisions, then paging reception reliability improves, but communication overhead increases due to additional signaling messages
Solution Approach 1:
The patent performs preliminary detection of paging occasion overlaps before actual paging reception. The terminal proactively identifies potential collisions by comparing paging occasion parameters from multiple base stations and sends adjustment requests in advance, preventing collisions before they occur rather than reacting after paging failures.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal monitors paging occasions, detects overlaps, and sends feedback messages to the network requesting parameter adjustments. The network responds with adjusted parameters, creating a closed-loop control system that optimizes paging reception while managing signaling overhead through targeted rather than continuous communication.
