UE Position Reporting Control for Out of Service Energy Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication systems face inefficiencies in managing position information reporting, leading to unnecessary processing loads and failure to detect 'Out of LTE Service' states, as they lack mechanisms to stop and restart position information reporting effectively.
Innovation Solution
A method and apparatus for a User Equipment (UE) to report position information at predetermined intervals, with a controller determining whether to stop reporting based on operation states, using a message generator, monitoring unit, and transmission controller to manage position information transmission according to the UE's operation state, grouping states into null, wait, and ready conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously reports position information at predetermined intervals, then the position information management server can maintain accurate position data, but the UE consumes excessive power and generates unnecessary processing loads when in 'Out of Service' areas
Solution Approach 1:
The patent applies dynamics by making the position reporting behavior adaptive rather than static. The UE dynamically adjusts its reporting behavior based on its operation state (connected or detached). When connected, the UE reports position information at predetermined intervals; when detached, the UE stops reporting. This dynamic adjustment resolves the contradiction between maintaining position accuracy and reducing power consumption.
Solution Approach 2:
The patent implements feedback mechanisms where the UE monitors its own operation state and the server acknowledges received position information. The UE detects when it transitions to a detached state and receives acknowledgment messages from the server, using this feedback to intelligently control when to stop and resume position reporting, thereby optimizing power consumption while maintaining necessary position tracking.
2Use of energy by moving object
If the UE stops position information reporting when moving to a new service area, then power consumption is reduced, but the system fails to detect 'Out of LTE Service' states and cannot restart reporting effectively
Solution Approach 1:
The patent uses feedback mechanisms where the UE monitors for acknowledgment messages from the position information management server. When the UE stops reporting due to detachment and later reattaches to the network, it can detect the resumption condition through server acknowledgments, enabling reliable service state detection without continuous reporting.
Solution Approach 2:
The UE performs self-monitoring of its operation state and autonomously decides when to stop and resume position reporting based on its own detected conditions (detached/attached states). This self-service approach allows the UE to manage its own power consumption while maintaining service detection capability through internal state tracking.
3Loss of information
If the UE reports position information in all operation states, then complete position tracking is maintained, but unnecessary processing loads are generated in null and wait conditions where reporting cannot succeed
Solution Approach 1:
The patent applies dynamics by making the position reporting behavior adaptive rather than static. The UE dynamically adjusts its reporting behavior based on its operation state (connected or detached). When connected, the UE reports position information at predetermined intervals; when detached, the UE stops reporting. This dynamic adjustment resolves the contradiction between maintaining position accuracy and reducing power consumption.
Solution Approach 2:
The patent implements partial action by having the UE report position information only in the ready condition when reporting can be successful, rather than continuously in all conditions. The UE performs position reporting partially (only when necessary and effective) based on its operation state, avoiding wasteful processing in null and wait conditions while maintaining complete tracking when actually connected.

AI summary
An apparatus and a method for registering a position, which periodically update a position of a user in a mobile communication system are provided. The method includes determining whether to stop reporting position information based on a current operation state for a mobile communication service and controls whether to maintain or stop reporting the position information based on a result corresponding to the determination. Accordingly, it is possible to increase an energy efficiency by preventing an unnecessary position registering step from being performed by a User Equipment (UE) in an Out of Service (OS) area.
