Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems, such as those using Voice over IP (VoIP), lack the ability to seamlessly integrate and enrich voice calls with additional services like video or conferencing during an ongoing session, requiring explicit configuration and participant initiation, and do not allow for dynamic establishment of additional service sessions.

Innovation Solution

A method and system that establish a first communication session and a second communication session, with stored relation information, enabling automatic termination and enhanced control of service sessions, allowing enrichment of voice calls with additional services without explicit participant action, using a call control application server and multimedia IP network to semantically relate sessions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional service sessions are established during a running communication session, then service enrichment capability is improved, but session management complexity increases

Engineering Contradiction:

Improveservice enrichment capabilityVSAvoidsession management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a session manager as an intermediary component that handles the complexity of managing multiple communication sessions. The session manager maintains session information including primary sessions, secondary sessions, and their relationships, thereby enabling service enrichment without directly increasing the complexity of individual terminal devices. The session manager acts as a mediator that coordinates between different sessions and terminal modules.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If explicit configuration and participant action are required for service integration, then service control precision is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveservice control precisionVSAvoidease of service integration

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent implements automatic session establishment mechanisms where the session manager can autonomously create and manage secondary sessions based on predefined rules and session relationships. When a primary session is established, the system can automatically initiate related secondary sessions without requiring explicit participant actions for each service. This self-service approach maintains service control precision through automated rule-based management while significantly improving ease of operation.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If terminal devices with special capabilities are used for service combination, then service functionality is improved, but device accessibility deteriorates

Engineering Contradiction:

Improveservice functionalityVSAvoiddevice accessibility

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The session manager serves as an intermediary that offloads the complexity of managing multiple service sessions from individual terminal devices. Instead of requiring terminal devices to have sophisticated capabilities for service combination, the session manager centralized in the network handles session coordination, relationship management, and service enrichment. This allows standard terminal devices to access advanced service functionality through the session manager's mediation.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If services are selected by session initiator prior to session establishment, then service selection control is improved, but flexibility deteriorates

Engineering Contradiction:

Improveservice selection controlVSAvoidservice establishment flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements a hybrid approach where service selection can occur both in advance and dynamically. The session manager stores session information and relationships that were preliminarily configured, enabling efficient service selection control.同时, the system allows dynamic establishment of secondary sessions during ongoing primary sessions based on runtime conditions and participant needs. This combination of preliminary configuration and dynamic adaptation resolves the contradiction between service selection control and establishment flexibility.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method for controlling communication between a number of first terminal modules connected to a multimedia IP network in particular with the first communication session being a call session already running, includes the steps of establishing a first communication session between the first terminal modules, establishing at least one second communication session between at least a subset of the first terminal modules, and storing relation information relating the first and the second communication sessions.
