VCC Function Notification for Terminal Resource Control

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing Voice Call Continuity (VCC) systems lack a mechanism for the network server to indicate to terminals whether VCC functions can be supported, leading to unnecessary resource consumption and inefficiencies when network conditions are unfavorable.

Innovation Solution

A method and system where the network server sends VCC function notification messages to terminals, including enabling or disabling information, allowing terminals to adjust their VCC functions accordingly, and for the network server to selectively perform VCC operations based on this information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal continuously performs VCC operations without network indication, then the terminal maintains readiness for VCC functions, but unnecessary resource consumption occurs when network conditions are unfavorable

Engineering Contradiction:

ImproveVCC function availabilityVSAvoidterminal resource consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The network server sends VCC function notification messages to the terminal, providing feedback about current network conditions and VCC support status. This feedback mechanism allows the terminal to adjust its behavior based on actual network capabilities, avoiding unnecessary resource consumption while maintaining reliability when conditions are favorable.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The terminal dynamically adjusts its VCC function status based on received network indications. When the network server indicates VCC support, the terminal enables VCC functions; when not supported, the terminal disables them. This dynamic adaptation resolves the contradiction by making the system responsive to changing network conditions rather than continuously operating at fixed state.

Inventive Principle:

Principle #15Dynamics

2Productivity

If the terminal performs VCC operations without network confirmation, then the terminal can initiate domain transfers, but network inefficiency occurs due to unsupported operations

Engineering Contradiction:

ImproveVCC operation speedVSAvoidnetwork resource waste

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The network server performs preliminary action by sending VCC function notification messages to indicate whether VCC operations are supported before the terminal attempts any VCC operations. This advance notification prevents the terminal from initiating unsupported domain transfers, thereby avoiding network inefficiency while allowing rapid operation when conditions are favorable.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If the network lacks a VCC indication mechanism, then the system architecture remains simple, but information loss occurs regarding network VCC support status

Engineering Contradiction:

Improvesystem architectureVSAvoidVCC support information

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent introduces an intermediary message (VCC function notification message) that carries VCC support information from the network server to the terminal. This intermediary mechanism adds minimal complexity to the system architecture while effectively transmitting the critical information about network VCC support status, resolving the information loss problem.

Inventive Principle:

Principle #24Intermediary (Mediator)
