IPTV Notification Differentiation via IARI in Instant Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IPTV systems cannot effectively differentiate IPTV notifications from other instant messages received by the end-user without adding complexity to the server, making it difficult for users to identify and manage IPTV-related messages.
Innovation Solution
Incorporating an IMS Application Reference Identifier (IARI) and OMA IM feature tag in instant messages to identify IPTV applications associated with a Service Control Function node, allowing User Equipment to filter and parse notifications, displaying relevant information and providing options like accepting, canceling, or snoozing IPTV programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IPTV notifications are sent as regular instant messages, then the messaging service can be used universally, but the user cannot differentiate IPTV notifications from other messages
Solution Approach 1:
The patent applies local quality by adding specific identifying characteristics (IARI and feature tags) only to IPTV notification messages, while leaving other messages unchanged. This allows the messaging service to remain universal while giving IPTV messages distinctive local properties that enable differentiation at the user device without affecting the overall messaging system.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of application identifiers and feature tags that mediate between the messaging service and the user device. These intermediaries carry identification information through the message stream, enabling the user device to differentiate IPTV notifications without requiring changes to the core messaging service infrastructure.
2Loss of information
If application identifiers are added to differentiate IPTV messages, then message differentiation is achieved, but the server complexity increases
Solution Approach 1:
The patent applies self-service by enabling the user device to autonomously differentiate and process IPTV notification messages using the application identifiers and feature tags. The user device itself performs the differentiation task rather than requiring complex server-side processing, thus reducing server complexity while maintaining effective message identification.
Solution Approach 2:
The patent changes parameters of the message structure by adding application identifiers and feature tags, which are lightweight metadata elements. These parameter changes enable message differentiation without fundamentally altering the messaging service architecture or significantly increasing server complexity.
3Loss of information
If all instant messages are displayed to the user, then no information is lost, but the user cannot efficiently identify IPTV-related messages
Solution Approach 1:
The patent applies a metaphorical 'color change' by introducing visual or functional distinctions (through application identifiers and feature tags) that allow users to quickly identify IPTV notification messages among other messages. This enables efficient identification without filtering out any messages, maintaining information completeness while improving ease of operation.

AI summary
Methods and arrangements for presenting a received Instant Message comprising an IPTV Notification, e.g. a Program Reminder, and differentiating the IM comprising the IPTV Notification from other Instant Messages received from other users. The differentiation is achieved by the SCF-node (3) (Service Control Function), e.g. an IAP (IPTV Application Platform), including an IARI (IPTV Application Reference Identifier) in an Instant Message comprising an IPTV Notification. The IARI identifies an IPTV Application of the SCF (Service Control Function), and indicates to a UE (1) at the receiving side that the Instant Message comprises IPTV information for presenting an IPTV Notification.
