Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wireless communication systems face challenges in managing and establishing voice over Internet protocol (VoIP) calls, particularly in differentiating and enabling various call types within VoIP session identifiers, which affects network components' ability to efficiently manage voice services.

Innovation Solution

The implementation of VoIP modules in wireless communication networks generates and distributes VoIP session identifiers (VSIDs) using Session Initiation Protocol (SIP) messages, enabling authentication and call type differentiation by generating and managing VSIDs that indicate enabled or disabled status for different call types, ensuring proper call setup and termination processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If VoIP session identifiers are used to manage voice calls over IP network, then voice call establishment and management is enabled, but differentiation of various call types within the session identifiers becomes challenging

Engineering Contradiction:

Improvecall type differentiationVSAvoidsession identifier management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The VoIP session identifier (VSID) is segmented into multiple fields including a call type field that specifically identifies the type of voice call. This segmentation allows the system to differentiate between various call types (emergency, non-emergency, free, non-free, international, domestic) within the overall session identifier structure, resolving the contradiction by organizing complexity into manageable segments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent adds a call type dimension to the traditional VoIP session identifier by incorporating a specific call type field. This dimensional addition allows the system to distinguish between different call categories without fundamentally changing the core session management mechanism, enabling call type differentiation while maintaining compatibility with existing VoIP infrastructure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If network components manage voice calls with differentiated call types, then service management capability is improved, but the complexity of establishing and managing calls increases

Engineering Contradiction:

Improvevoice service management efficiencyVSAvoidcall management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The call type information is embedded within the VSID during the initial session establishment phase. This preliminary action ensures that call type differentiation is already in place before call management operations begin, allowing network components to efficiently manage different call types without adding complexity to ongoing call handling procedures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The VoIP session identifier serves multiple functions simultaneously: it identifies the voice call session, differentiates call types, and enables appropriate routing and management. This multi-functionality improves productivity by using a single identifier structure for multiple purposes rather than requiring separate mechanisms for session management and call type differentiation.

Inventive Principle:

Principle #6Universality (Multi-functionality)
