Session Transfer via Network Server Capability Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring communication sessions between devices result in high link utilization and CPU load on the source device, leading to battery drain and suboptimal content quality when transferring sessions to devices with different capabilities, such as from a smartphone to a television.
Innovation Solution
A method where a source user device determines the identifier of a target user device and sends a session modification request to a network server, which checks the target device's capability to handle the session and establishes a new communication session if capable, using a target ID container and device information database to ensure optimal transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automated connection setup methods are used to transfer sessions between wireless devices, then session transfer capability is improved, but link utilization and CPU load on the source device increase
Solution Approach 1:
The patent extracts the session management functions from the source device and relocates them to the network server. The source device only needs to send a session transfer request containing target device identifier, while the server handles session modification, capability checking, and connection establishment. This extraction eliminates the need for continuous device-to-device communication protocols and reduces CPU load on the source device.
Solution Approach 2:
The network server acts as an intermediary between the source device and target device. Instead of direct peer-to-peer communication requiring complex wireless protocols and authentication, the server mediates the session transfer by receiving requests from the source device, verifying target device capabilities, and establishing connections. This intermediary approach simplifies the source device's role and reduces its energy consumption.
2Adaptability or versatility
If sessions are transferred to devices with different capabilities, then device versatility is improved, but content quality deteriorates
Solution Approach 1:
The patent implements a capability checking mechanism where the network server verifies whether the target device has the necessary capabilities to handle the communication session before transferring it. The server receives capability information from the target device and uses this feedback to determine if the transfer should proceed. This feedback loop ensures that sessions are only transferred to devices that can maintain acceptable content quality, preventing degradation when transferring to incompatible devices.

AI summary
A method for transferring a communication session between a source user device and a target user device in a communication network, where the communication session is established between the source user device and a server is proposed. An identifier of a user device is determined. A session modification request is then sent from the source user device to the server, where the request includes the identifier of the target user device. A capability of the target user device to handle the communication session is then checked. Next, if the target user device is capable of handling the communication session a further communication session between the server and the target user device is established.
