Solution Overview
Problem
Current wireless communication systems lack efficient methods for managing terminal mobility, particularly in scenarios where service disruptions occur, leading to gaps in network coverage and user experience.
Innovation Solution
The proposed solution involves a method and device for a terminal in a wireless communication system to receive capability information about utilizing a secondary communication provider's network during service disruptions. This includes confirming service disruptions, scanning for alternative networks, and selecting a network for registration based on available information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal uses traditional mobility management methods, then the network coverage is limited to the subscribed communication provider's network, but the service continuity is interrupted when service disruption occurs
Solution Approach 1:
The terminal performs preliminary actions by storing capability information about alternative communication providers before service disruption occurs. When the subscribed network experiences service disruption, the terminal can immediately switch to an alternative network using pre-stored capability information, ensuring service continuity without delay.
Solution Approach 2:
The terminal dynamically adjusts its network selection based on service disruption detection. The system transitions from a static network attachment state to a dynamic state where the terminal can scan, evaluate, and switch to alternative networks, maintaining service continuity through adaptive network selection.
2Reliability
If the terminal scans for alternative networks during service disruption, then the service continuity is improved, but the time required for network switching increases
Solution Approach 1:
Capability information about alternative communication providers is stored in advance before service disruption occurs. This preliminary action eliminates the need for time-consuming network scanning and evaluation during disruption, enabling immediate switching to alternative networks while maintaining service continuity.
Solution Approach 2:
The terminal skips the traditional time-consuming network scanning and evaluation process by utilizing pre-stored capability information. This allows the terminal to rapidly switch to alternative networks during service disruption, minimizing network switching time while ensuring service continuity.
3Speed
If the terminal stores capability information about alternative networks, then the network switching speed is improved, but the device complexity increases
Solution Approach 1:
The stored capability information about alternative communication providers serves multiple functions: it enables rapid network switching during service disruption, provides basis for network selection, and supports mobility management. This multi-functionality justifies the additional information storage by delivering significant performance benefits across multiple operations.
Solution Approach 2:
The terminal autonomously manages the stored capability information about alternative networks, performing self-service in network selection and switching decisions. This self-service capability reduces the need for complex external control mechanisms, making the information management system more efficient despite the additional data storage requirements.
