Private Cloud Session Migration for Seamless Device Handoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems are inflexible, forcing users to restart active sessions on different devices, leading to delays and frustration, and lack the ability to preserve session state across devices, which limits user experience and resource efficiency.
Innovation Solution
A system that allows seamless migration of active communication sessions between devices using a private cloud, which registers and authenticates devices, stores session information, and transfers it to another device for restoration, while enforcing network policies and maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional communication systems are used, then security and device-specific access are maintained, but users cannot migrate active sessions between devices and must restart sessions, leading to delays and frustration
Solution Approach 1:
The patent extracts the session state from the specific device context and stores it in a cloud-based session manager. This allows the session to be independently maintained and accessed from multiple devices, enabling seamless migration without restarting the session.
Solution Approach 2:
The patent introduces a cloud-based session manager as an intermediary between the user and communication services. This mediator maintains session states and enables transfer between devices, resolving the contradiction by providing both security (through controlled access) and ease of operation (through session migration).
2Adaptability or versatility
If conventional communication systems are used, then device-specific access control is enforced, but the system cannot preserve session state across devices, limiting user experience
Solution Approach 1:
The patent implements a universal session management system that can be accessed from multiple devices. The session manager maintains session states in a cloud-based storage, allowing any authorized device to restore the session, thereby providing multi-device adaptability while preserving session information.
Solution Approach 2:
The patent performs preliminary actions by storing session state information in the cloud before device switching occurs. This advance preparation ensures that when the user switches devices, the session state is already available for restoration, preventing information loss and enabling seamless continuity.
3Ease of operation
If session information is stored and transferred between devices, then session migration is enabled, but network security policies must be enforced to prevent unauthorized access
Solution Approach 1:
The patent implements self-service mechanisms where the session manager automatically handles authentication and authorization checks during session migration. The system uses stored device identifiers and security tokens to verify permissions without requiring complex manual authentication, enabling seamless transfer while maintaining security through automated processes.
Data Source
AI summary
The migration of a communication session from one device to another device may include registering at least two devices, authenticating user credentials at the second device, determining whether transfer of the session is authorized, storing session information associated with the session, transmitting the stored session information to the second device, and receiving a request that incorporates the transmitted session information to restore the communication session on the second device. In addition, access to the system may be prohibited from the first device for a predefined period of time.
