SUPL Terminal Notification Mode Parameter Handling
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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
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.

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.
