Solution Overview

Problem

Existing Session over Internet Protocol (SoIP) networks lack the ability to dynamically prioritize IP packets based on quality-of-service parameters, which limits their flexibility and efficiency in managing call routes and connections.

Innovation Solution

A method that involves receiving media-content packets within a SoIP network, identifying transmission priority values based on quality-of-service parameters, and modifying priority indicators to adjust the transmission priority of these packets, utilizing a priority database and session-aware equipment to dynamically manage packet prioritization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If SoIP networks use IP packet switching for fast call setup and route management, then call establishment speed and network flexibility improve, but the ability to dynamically prioritize packets based on quality-of-service parameters deteriorates

Engineering Contradiction:

Improvecall establishment speedVSAvoiddynamic packet prioritization capability

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The patent segments the packet handling process by introducing session-aware components that operate at the session layer (Layer 5) of the OSI model. These components separate the fast IP packet switching function from the QoS prioritization function, allowing packets to be rapidly routed while session-aware components independently analyze QoS parameters and adjust priorities without blocking the fast path of IP forwarding.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces session-aware components as intermediary elements between the IP packet switching infrastructure and the application layer. These intermediaries monitor QoS parameters, interpret session information, and dynamically adjust packet priorities without disrupting the underlying fast IP switching mechanism, thus bridging the gap between speed and adaptability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional circuit-committed networks are used, then quality-of-service guarantee is improved, but network flexibility and call setup speed deteriorate

Engineering Contradiction:

Improvequality-of-service guaranteeVSAvoidnetwork flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical circuit-committed approach with an intelligent packet-switching system enhanced by session-aware components. Instead of physically dedicating resources, the system uses software-based QoS parameter monitoring and dynamic priority adjustment to guarantee service quality, maintaining reliability while achieving the flexibility of packet switching.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements feedback mechanisms where session-aware components continuously monitor QoS parameters of active sessions and dynamically adjust packet priorities in response to changing conditions. This closed-loop control ensures quality-of-service guarantees are maintained while adapting to network conditions and session requirements in real-time.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If session-aware equipment is introduced to enable packet prioritization, then quality-of-service management capability is improved, but device complexity increases

Engineering Contradiction:

Improvequality-of-service management capabilityVSAvoidsession-aware equipment complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs session-aware components with multi-functionality, enabling them to perform QoS monitoring, priority adjustment, session management, and traffic classification simultaneously. This consolidation of functions into unified components achieves comprehensive QoS management without proportionally increasing complexity, as a single component handles multiple responsibilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements preliminary action by having session-aware components establish QoS policies and priority rules during session setup phases. By pre-configuring prioritization parameters before actual media transmission begins, the system avoids complex real-time decision-making during active communication, reducing operational complexity while maintaining adaptability.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method includes receiving a first media-content packet associated with a first session within a Session over Internet Protocol (SoIP) network. The first media-content packet is associated with a quality-of-service parameter. A transmission priority value associated with the first media-content packet is identified based on a value of the quality-of-service parameter. A priority indicator associated with the first media-content packet and/or a second media-content packet is modified based on the transmission priority value. The priority indicator indicates a priority to transmit the first media-content packet and/or the second media-content packet over a connection within the first session and/or a connection within a second session.
