Solution Overview

Problem

Existing telecommunication systems face difficulties in providing efficient and effective call management and participant visibility for users with wireless devices, which have restricted bandwidth connections and processing capacity, especially during conference calls.

Innovation Solution

A method involving a status proxy server that establishes a full bandwidth connection with a media server and a reduced bandwidth connection with mobile end user devices, using the SIP protocol to communicate call status updates at optimized intervals, reducing bandwidth and processing demands on the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If full bandwidth connection and complete SIP protocol data are used for call management, then call management functionality and real-time status updates are improved, but bandwidth consumption and processing requirements on mobile devices increase significantly

Engineering Contradiction:
Improvecall management functionalityVSAvoidbandwidth consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential call status information from the complete SIP protocol data stream. The status proxy server filters and selects specific status indicators (e.g., call state, participant presence) while discarding redundant protocol details, thereby reducing data transmission volume while preserving core call management functionality on bandwidth-constrained mobile devices

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The status proxy server acts as an intermediary between the media server and mobile end user devices. It receives comprehensive SIP protocol data from the media server, processes and simplifies it into essential status indicators, and forwards only the necessary information to mobile devices. This intermediary layer shields mobile devices from protocol complexity and bandwidth-intensive data transmission

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If frequent real-time status updates are communicated to mobile devices, then call management responsiveness is improved, but bandwidth usage and network load increase

Engineering Contradiction:
Improvestatus update responsivenessVSAvoiddata transmission volume
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The status proxy server implements periodic action by communicating call status updates to mobile devices at optimized time intervals rather than continuously. It monitors status changes and triggers updates only when significant state transitions occur, balancing real-time responsiveness with bandwidth conservation by avoiding redundant frequent transmissions of unchanged status information

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system applies partial action by transmitting only the essential call status indicators needed for mobile device functionality rather than complete protocol data sets. This selective transmission provides sufficient information for call management while significantly reducing data volume compared to exhaustive status reporting

Inventive Principle:
Principle #16Partial or excessive action

3Measurement precision

If complete SIP protocol data sets are processed on mobile devices, then call management accuracy is improved, but processing capacity requirements and device complexity increase

Engineering Contradiction:
Improvecall status accuracyVSAvoidprocessing capacity requirements
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The status proxy server extracts and forwards only the essential call status indicators required for accurate call management on mobile devices. By filtering out redundant SIP protocol elements and transmitting only critical status information (e.g., call state, participant presence), it maintains measurement precision while dramatically reducing the processing capacity requirements on bandwidth-constrained mobile devices

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The status proxy server serves as an intermediary that performs data processing and simplification before information reaches mobile devices. It handles the complexity of interpreting complete SIP protocol data sets, transforming them into simplified status indicators that maintain accuracy while being computationally efficient for mobile device processing

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A status proxy server having a full bandwidth connection with a media server and wireless connection with a mobile end user device, receives SIP or similar protocol structured data; maintains a status indicator representative of the received structured data; and communicating at time intervals an update of the status indicator to the mobile end user device.
