HTTP-OTA Session Initiation via Voice Call Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HTTP-OTA session initiation methods in mobile networks face compatibility issues due to reliance on SMS, user involvement, and high battery consumption, particularly in 4G and 5G networks.
Innovation Solution
The method initiates an HTTP-OTA session using voice calls or MDM messages, eliminating the need for SMS and user input, and integrates with existing HTTP-POLL mechanisms to reduce battery consumption and delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If HTTP-PUSH mechanism using SMS is used to initiate HTTP-OTA session, then remote management capability is improved, but compatibility with existing mobile networks deteriorates
Solution Approach 1:
The patent introduces a message forwarding mechanism where the SMS message acts as an intermediary to trigger a voice call notification. The HTTP-OTA platform sends an SMS to a designated number, which then triggers a voice call to the mobile device. This intermediary approach allows the system to maintain compatibility with networks that still support SMS while achieving the automated remote management goal without requiring direct SMS-to-secure-element communication.
Solution Approach 2:
The patent replaces the SMS-based notification mechanism with a voice call-based notification mechanism. Instead of relying on SMS messages to directly initiate HTTP-OTA sessions (which has compatibility issues), the system substitutes SMS with voice calls that are more universally supported across mobile networks and devices, thereby improving network compatibility while maintaining automated remote management capability.
2Speed
If HTTP-POLL mechanism is used with short polling intervals to reduce update delay, then update speed is improved, but battery consumption increases
Solution Approach 1:
The patent implements a voice call-based notification system that operates periodically only when needed, rather than continuous polling. The HTTP-OTA platform initiates a voice call notification when an update is ready, and the secure element responds only when triggered by this external notification. This periodic action approach eliminates the need for continuous short-interval polling, thereby reducing battery consumption while maintaining fast update response times.
Solution Approach 2:
The system performs preliminary action by having the HTTP-OTA platform proactively notify the mobile device via voice call when an update is ready, before the secure element would otherwise need to poll. This preliminary notification triggers the update process only when necessary, avoiding continuous polling and reducing energy consumption while ensuring updates are initiated promptly when available.
3Use of energy by moving object
If HTTP-POLL mechanism is used with prolonged polling intervals to reduce battery consumption, then energy efficiency is improved, but update delay increases
Solution Approach 1:
The patent uses periodic voice call notifications from the HTTP-OTA platform to trigger updates only when needed, rather than relying on long-interval polling. This approach maintains energy efficiency by avoiding continuous polling while ensuring that updates are initiated promptly when the platform has content ready, thus reducing update delay compared to prolonged polling intervals.
Solution Approach 2:
The system implements feedback through the voice call notification mechanism, where the HTTP-OTA platform provides real-time feedback to the mobile device when updates are available. This feedback loop allows the system to respond immediately to update availability without waiting for prolonged polling intervals, thus reducing update delay while maintaining energy efficiency.
4Ease of operation
If user input is required to initiate HTTP-OTA session to ensure user awareness, then user control is improved, but ease of operation deteriorates
Solution Approach 1:
The patent introduces a voice call notification as an intermediary between the HTTP-OTA platform and the user. Instead of requiring direct user input to initiate updates, the system uses automated voice call notifications to alert users of available updates. This intermediary approach maintains user awareness and control while eliminating the need for manual user initiation, thereby improving ease of operation while preserving user control through notification-based awareness.

AI summary
The invention refers to a method for establishing an HTTP-OTA session (HS) between a secure element (3) connected to a mobile device (2) and an HTTP-OTA platform (1) within a mobile network. In the method of the invention, the HTTP-OTA platform (1) initiates a transmission of a first notification (N1) to the mobile device (2), the first notification (N1) comprising an MDM message (ME) or a voice call (VC). Thereafter, triggered by the first notification (N1) received in the mobile device (2), a second notification (N2) comprising one or more predetermined STK events (EV) and/ or one or more predetermined STK commands (CO) is transmitted by the mobile device (2) to the secure element (3). Finally, triggered by the second notification (N2) received in the secure element (3), an HTTP-OTA session (HS) with the HTTP-OTA platform (1) is initiated by the secure element (3).
