Solution Overview

Problem

In a Secure User Plane Location (SUPL) network, there is no clear method for a terminal to determine whether a notification request is based on its location, leading to unstable notification responses and unclear timing, as existing systems lack a mechanism to differentiate between location-based and non-location-based notifications.

Innovation Solution

A location-based notification method where a notification mode parameter is included in session initial messages, allowing the terminal to check if the notification is location-based, and only transmitting a session end message if it is not location-based, ensuring appropriate handling of notifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the location server transmits notification requests without indicating whether they are location-based, then the notification system is simple, but the terminal cannot determine the notification type leading to unstable responses

Engineering Contradiction:
Improvenotification response stabilityVSAvoidsignal transfer system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a notification mode parameter as an intermediary element that mediates between the location server's notification request and the terminal's response. This parameter acts as a carrier that conveys the notification type information without complicating the overall system architecture, enabling stable terminal responses while maintaining signal transfer simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the state of the notification system by introducing a new parameter (notification mode parameter) that can take different values to indicate different notification types. This parameter change enables the terminal to distinguish between location-based and non-location-based notifications, improving response stability without requiring fundamental system restructuring.

Inventive Principle:
Principle #35Parameter changes

2Loss of time

If the terminal always transmits notification responses immediately, then the response time is short, but the timing becomes unclear when location-based notifications are involved

Engineering Contradiction:
Improvenotification response timingVSAvoidnotification system stability
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the terminal checks the notification mode parameter received from the location server and adjusts its response timing accordingly. When the parameter indicates a location-based notification, the terminal waits for appropriate location determination before responding, ensuring timely and reliable responses without creating timing ambiguity.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If no differentiation mechanism is provided for notification types, then the system is simple, but user privacy control based on location cannot be implemented

Engineering Contradiction:
Improveprivacy policy adaptabilityVSAvoidnotification system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the notification system by introducing a notification mode parameter that divides notifications into distinct categories (location-based and non-location-based). This segmentation enables differentiated privacy control policies for different notification types while maintaining a relatively simple overall system structure through the use of a single distinguishing parameter.

Inventive Principle:
Principle #1Segmentation

AI summary

A system and method for performing a notification based upon location in a Secure User Plane Location (SUPL) network which is provided with a SUPL Location Platform (SLP) and a SUPL Enabled Terminal (SET) to thus perform a privacy authentication based upon a location of the SET, wherein when a client requests positioning of the SET, the SLP transmits a notification mode parameter to the SET through a session initial message, whereby it can be predefined whether the notification is performed based upon a location or a user when the SLP (i.e., server system) notifies the SET (or the SET user) of the positioning of the SET requested by the client (i.e., a client system), thus to enable the SET to determine a time point of a notification response.
