Solution Overview

Problem

Current communication technologies face user confusion due to the inability of autonomous networks to seamlessly interwork, particularly in scenarios involving multiple networks and roles, leading to inconsistencies in accessing collaboration services across different network zones.

Innovation Solution

An electronic device can connect to multiple autonomous networks through various interfaces, enabling seamless call control and collaboration services by associating with both public and private networks, allowing for the addition or deletion of participants and providing features such as role management and device handoff, using protocols like SIP for communication between controllers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a user connects to multiple autonomous networks (public and private), then the user can access more collaboration services and roles, but the user experiences confusion and ambiguity in control between networks

Engineering Contradiction:
Improveaccess to collaboration servicesVSAvoiduser confusion
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a mediation mechanism where the network controller acts as an intermediary between the user device and multiple autonomous networks. The controller receives service requests from the user device, determines which network (public or private) should fulfill the request based on role associations, and routes the request accordingly. This intermediary approach resolves user confusion by automatically managing network selection and control ambiguity without requiring user intervention.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements a universal service request handling mechanism that works across multiple autonomous networks. The network controller is designed to handle service requests from both public and private networks using the same interface and processing logic. This multi-functional approach allows the system to provide consistent collaboration services regardless of which autonomous network is involved, eliminating the need for users to understand or manage the differences between networks.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the system provides role-based collaboration services across multiple networks, then service functionality is enhanced, but control ambiguity and complexity increase

Engineering Contradiction:
Improverole-based servicesVSAvoidcontrol complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex control logic for managing role-based services from the user device and places it in the network controller. The controller contains the intelligence to determine which network should fulfill a service request based on role associations between users and networks. This extraction simplifies the user device while enhancing the controller's capabilities, reducing overall system complexity by centralizing control functions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements self-service functionality where the network controller automatically determines network selection and service routing based on pre-defined role associations. The controller monitors user roles, network memberships, and service requests to autonomously manage call control without requiring complex user input or manual configuration. This self-service approach reduces control complexity by automating decision-making processes.

Inventive Principle:
Principle #25Self-service

3Reliability

If IMS network is deployed to manage autonomous network control, then control ambiguity is reduced, but system cost and complexity increase

Engineering Contradiction:
Improvecontrol clarityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the control function into a dedicated network controller component that is separate from both the user device and the autonomous networks. This segmentation allows the controller to manage interactions between multiple networks independently, providing clear control without requiring the entire IMS network infrastructure. The segmented approach reduces overall system complexity while maintaining control clarity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of implementing the full IMS network architecture, the patent applies a partial action approach by implementing only the essential control functions needed for managing autonomous network interactions. The network controller performs the specific tasks of receiving service requests, determining network selection based on roles, and routing requests, without requiring the complete IMS infrastructure. This partial implementation achieves control clarity at lower system complexity and cost.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The present disclosure relates to communications, and more particularly, to a seamless interworking of call control between autonomous systems. In an illustrative embodiment, an electronic device is provided. The electronic device can be connected to multiple autonomous networks, for example, a private network through a Private Branch Exchange and a public network through a Public Switched Telephone Network. The user device can have multiple network interfaces. Alternatively, there can be one network interface to access the autonomous networks. These networks each can provide unique collaboration services. Collaboration services can include, but are not limited to, associations, roles, availability and features. The electronic device can setup connections and initialize a call through both networks. Through the device, each of the networks can add or delete participants to the call under the direction of the user. The networks can also provide the user device with suitable feature keys.
