Push Notification Location Updates in LTE Direct
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE technologies face challenges in efficiently managing location information updates and authorization for user equipment (UE) in proximity services, leading to resource wastage and inaccurate location determination.
Innovation Solution
A method and apparatus that utilize push notifications to trigger UE to update location information, involving a network device that receives requests for location information, determines authorization, and sends messages to initiate reporting, ensuring secure and efficient location updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If LTE direct proximity services continuously update and broadcast location information, then location accuracy is improved, but network resources and device energy are wasted
Solution Approach 1:
The system implements periodic location updates triggered by push notifications from the network rather than continuous broadcasting. The network device sends notifications at specific intervals or when location changes are detected, causing UEs to update and broadcast location information only at these periodic moments, thereby maintaining accuracy while reducing energy consumption and network resource usage.
Solution Approach 2:
The network device monitors UE location changes and autonomously determines when push notifications should be sent to trigger location updates. This self-service mechanism eliminates the need for continuous UE-initiated location requests and responses, allowing the system to maintain accurate location information while minimizing unnecessary network traffic and device energy consumption.
2Loss of information
If LTE direct proximity services broadcast location information to all UEs, then location information availability is improved, but security and authorization control deteriorate
Solution Approach 1:
The system applies different authorization levels and information sharing policies to different UE pairs or groups. Instead of uniform broadcasting to all UEs, the network device evaluates authorization credentials specific to each requesting UE and grants location information access only to authorized devices, maintaining security while ensuring information availability to legitimate users.
Solution Approach 2:
The network device acts as an intermediary between UEs seeking location information and UEs providing location data. It receives location information from announcing UEs, verifies authorization credentials of requesting UEs, and selectively distributes location information only to authorized devices. This intermediary role maintains both security and information availability by controlling access at the network level.
