Terminal-Based Localized Message Delivery with Adaptive Location Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for delivering location-based messages in mobile networks are costly in terms of resources and intrusive on user privacy, as they require continuous activation of precise location services to determine if a user is within the message delivery zone.
Innovation Solution
Implementing a method where the user's terminal decides on message delivery based on geographic location, using rough localization means initially and activating more precise means only when necessary, thus minimizing resource consumption and respecting user privacy by reducing location data transmission to the central server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If precise location services are continuously activated to determine message delivery zone entry, then message delivery accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the location service precision adjustable and changeable over time. The system transitions from continuous high-precision GPS tracking to periodic coarse-location checks, dynamically adapting the measurement precision based on whether the terminal is in proximity to the message delivery zone. This resolves the contradiction by allowing high accuracy only when necessary (when approaching the zone) and using lower energy coarse location otherwise.
Solution Approach 2:
The patent implements periodic action by checking the terminal's location at defined intervals rather than continuously. The terminal performs periodic location updates and sends them to the server, which then determines whether the terminal has entered the message delivery zone. This periodic checking mechanism reduces energy consumption while maintaining the ability to detect zone entry accurately.
2Reliability
If continuous location tracking is implemented to ensure accurate message delivery, then delivery reliability is improved, but network resource consumption increases
Solution Approach 1:
The patent extracts the location determination function from the server and places it in the terminal. Instead of the server continuously tracking the terminal's location, the terminal independently determines its own location and only communicates with the server when it enters or exits the message delivery zone. This extraction of the location tracking function significantly reduces network bandwidth consumption while maintaining delivery reliability through event-driven communication.
Solution Approach 2:
The terminal performs self-service by autonomously monitoring its own location and independently determining when it has entered or exited the message delivery zone. The terminal then autonomously triggers message reception or sends notifications to the server. This self-service approach eliminates the need for continuous server-side location tracking and reduces network resource consumption.
3Loss of time
If the terminal continuously sends location updates to the server, then message delivery timeliness is improved, but privacy protection deteriorates
Solution Approach 1:
The patent extracts the location data processing function from the server and places it in the terminal. The terminal independently determines whether it has entered the message delivery zone based on its own location calculations and only sends minimal notification messages to the server when relevant events occur. This extraction ensures timely message delivery while protecting privacy by preventing continuous transmission of detailed location information to the server.
4Use of energy by moving object
If coarse location methods are used to reduce energy consumption, then energy efficiency is improved, but location precision deteriorates
Solution Approach 1:
The patent applies dynamics by making the location service precision adjustable and changeable over time. The system transitions from continuous high-precision GPS tracking to periodic coarse-location checks, dynamically adapting the measurement precision based on whether the terminal is in proximity to the message delivery zone. This resolves the contradiction by allowing high accuracy only when necessary (when approaching the zone) and using lower energy coarse location otherwise.

AI summary
The invention concerns a method for delivering at least one so-called "localised" message to a recipient using a terminal connected to a telecommunications network, such message being associated with a delivery area, said mobile terminal comprising first and second localisation means of said terminal. According to the invention, said method comprises the following steps, implemented by the terminal of the recipient: obtaining a piece of information representative of the delivery area associated with said at least one localised message; obtaining a first localisation area of the terminal of the user using the first localisation means of said terminal; when an intersection between the first obtained localisation area of the terminal and the geographical delivery area of the message is not empty, obtaining a second localisation area (Z2) of the terminal, which is more accurate than the first, delivering the content, when an intersection between the second obtained localisation area of the terminal and the geographical delivery area of the message is not empty; and deactivating (D10) the second localisation means when the delivery area of said at least one message and the first localisation area of the terminal have an empty intersection.
