PoC Presence Notification Filtering via Local Quality

Solution Overview

Problem

Existing Push-to-talk-over-Cellular (PoC) networks face challenges in providing a superior user experience while efficiently using network resources, leading to inferior user experiences and inefficient resource utilization.

Innovation Solution

A system and method for effective presence in PoC networks, utilizing servers to manage PoC call sessions, optimize presence notifications, and employ predictive and reactive methods to determine relevant presence information, reducing unnecessary messaging and optimizing network resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If presence notifications are sent to all PoC clients in the network, then all clients receive presence information, but network resource usage increases and battery life is reduced

Engineering Contradiction:

Improvepresence information availabilityVSAvoidnetwork resource usage

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The patent applies local quality by differentiating between relevant and irrelevant PoC clients for each presence notification. Instead of uniformly notifying all clients, the system selectively delivers notifications only to clients whose contact lists contain the presentity being notified. This selective approach maintains information availability for relevant clients while reducing network resource consumption by eliminating unnecessary notifications to irrelevant clients.

Inventive Principle:

Principle #3Local quality

2Loss of information

If presence notifications are sent to all PoC clients in the network, then all clients receive presence information, but handset battery life is reduced

Engineering Contradiction:

Improvepresence information availabilityVSAvoidhandset battery life

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by differentiating between relevant and irrelevant PoC clients for each presence notification. Instead of uniformly notifying all clients, the system selectively delivers notifications only to clients whose contact lists contain the presentity being notified. This selective approach maintains information availability for relevant clients while reducing network resource consumption by eliminating unnecessary notifications to irrelevant clients.

Inventive Principle:

Principle #3Local quality

3Loss of information

If presence information is delivered to all PoC clients, then complete presence data is available, but network load increases

Engineering Contradiction:

Improvepresence data completenessVSAvoidnetwork messaging volume

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent applies local quality by differentiating between relevant and irrelevant PoC clients for each presence notification. Instead of uniformly notifying all clients, the system selectively delivers notifications only to clients whose contact lists contain the presentity being notified. This selective approach maintains information availability for relevant clients while reducing network resource consumption by eliminating unnecessary notifications to irrelevant clients.

AI summary

A system and method for providing effective presence for Push-to-talk-over-Cellular (PoC) networks, wherein one or more servers performs an effective presence delivery method that reduces presence notifications delivered to mobile units participating in advanced voice services, while ensuring that the presence notifications relevant to the mobile units are available when the advanced voice services are invoked by the mobile units. The presence notifications are used to indicate a change in network presence of the mobile units. In addition, the presence notifications are used to indicate a change in self-availability status of the mobile units.
