WTRU Service Switching to Personal IoT Network Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack efficient methods for switching services between wireless transmit/receive units (WTRUs) and personal internet of things (IoT) networks (PINs), particularly in managing application sessions and determining suitable PINs for enhanced application experiences.
Innovation Solution
A WTRU receives a service switch request message, determines a second WTRU with suitable capabilities, sends configuration messages to facilitate session switching, and manages the transition between WTRUs and PINs, including PINEs, using PINE identifiers, IP addresses, and URLs to establish session endpoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service switching between WTRU and PIN is implemented, then application session management capability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a service switch function that acts as an intermediary between the WTRU and PIN, managing application session transitions. This mediator handles the complex session state management, capability matching, and coordination between different network elements, thereby enabling service switching without directly increasing the complexity of end devices.
Solution Approach 2:
The service switching functionality is segmented into distinct components including capability determination modules, session state management modules, and message handling modules. This segmentation allows each component to handle specific aspects of service switching independently, making the overall system more manageable and easier to implement despite the increased capability.
2Reliability
If capability determination for session switching is performed, then service compatibility is improved, but processing time increases
Solution Approach 1:
The patent performs capability determination actions in advance before actual service switching occurs. The service switch function determines whether the target PIN supports the required application session capabilities beforehand, and only proceeds with switching when compatibility is confirmed. This preliminary verification ensures service compatibility while allowing the actual switching operation to be executed efficiently without time loss.
3Adaptability or versatility
If multiple PINEs are involved in session switching, then service flexibility is improved, but coordination complexity increases
Solution Approach 1:
When multiple PINEs are involved in session switching, the service switch function acts as a central intermediary that coordinates between all PINEs and the WTRU. It manages the routing decisions, session state distribution, and synchronization across multiple PINEs, thereby enabling flexible multi-PINE service routing without requiring complex peer-to-peer coordination between the PINEs themselves.

AI summary
A wireless transmit/receive unit (WTRU) may receive a service switch message from a network node, requesting a session to be switched from the WTRU to a personal internet of things (loT) network (PIN) element (PINE). The PINE may be associated with the PIN. The WTRU may determine a second WTRU that supports session switching. The WTRU may send a confirmation message to the network node, indicating a session identifier and/or an indication indicating that the second WTRU supports the session switching. The WTRU may send a configuration message to the second WTRU, indicating a PINE identifier, the session identifier, and/or a request to support the session switching. The WTRU may receive a confirmation message from the second WTRU, indicating that the second WTRU has been configured to support the session switching. The WTRU may send a service switch response message to the network node.
