Terminal Location Context Continuity Across Network Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices experience low reliability when moving between different networks due to the need to cancel location requests and delete location contexts, leading to an inability to monitor triggers or periodic events and report location information effectively.
Innovation Solution
The terminal device maintains the location context and continues location requests when switching networks, allowing it to monitor for triggers or events and report location information, while also managing the location context appropriately based on specific conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the terminal device deletes the location context and cancels the location request when moving between networks, then the device complexity is reduced, but the reliability of location information reporting deteriorates
Solution Approach 1:
The terminal device performs preliminary actions by maintaining the location context and location request state before network movement occurs. This allows the device to have location information ready for immediate reporting upon entering a new network, eliminating the need to re-establish location requests after network switching.
Solution Approach 2:
The location monitoring and context maintenance operations continue uninterrupted during network transitions. The terminal device sustains the location request state across network boundaries, ensuring continuous location tracking capability without gaps that would occur with cancellation and re-initiation.
2Reliability
If the terminal device maintains the location context and continues location requests during network movement, then the reliability of location information reporting is improved, but the device complexity increases
Solution Approach 1:
The terminal device autonomously manages its own location context and maintains location requests without requiring external network coordination during movement. The device independently preserves location state information and continues monitoring, reducing the need for complex network-terminal interactions.
3Loss of time
If the terminal device cancels the location request when moving between networks, then the loss of time for re-establishing the request is reduced, but the loss of information about triggers and periodic events increases
Solution Approach 1:
The terminal device performs preliminary action by maintaining the location request state and associated trigger/periodic event information before network movement. This ensures that when the device enters a new network, it can immediately resume location reporting without losing track of monitoring requirements or event triggers.
Solution Approach 2:
The location monitoring operation continues uninterrupted during network transitions, maintaining continuous awareness of triggers and periodic events. The device sustains the location request state across network boundaries, ensuring no information about monitoring events is lost during the transition period.

AI summary
The present disclosure provides a communication method and apparatus, and a terminal device, including: in a case where the terminal device moves from a first network to a second network, not releasing, by the terminal device, a location context and skipping cancelling a location request, where through skipping cancelling the location request, the terminal device is caused to continue to monitor whether a request is triggered or a periodic event occurs, which enables the terminal device to report the location context in a case where it is monitored that the request is triggered or the periodic event occurs, thereby determining location information of the terminal device.
