PDU Session Distribution Across Multiple WTRUs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy systems limit content consumption to a single device, despite the presence of better devices nearby, and there is a need for efficient distribution of multicast-broadcast traffic and single PDU session management across multiple wireless transmit receive units (WTRUs) to enhance user experience.
Innovation Solution
Implementing a system that allows the distribution of a single PDU session among multiple WTRUs, enabling the separation and distribution of multimodal flows such as audio, video, and haptic data, and offloading functions to optimize resource utilization and user experience, using advanced network architectures like 5G systems.

Engineering Contradiction Analysis
1Productivity
If a single PDU session is distributed among multiple WTRUs, then content distribution efficiency and user experience are improved, but device complexity and network management complexity increase
Solution Approach 1:
The patent segments the PDU session into multiple sub-sessions or logical channels that can be independently managed and distributed to different WTRUs. This allows the single PDU session to be divided into manageable parts that can be allocated to multiple devices, improving distribution efficiency while controlling complexity through structured segmentation.
Solution Approach 2:
The patent implements dynamic resource allocation where the network can dynamically assign portions of the PDU session to different WTRUs based on real-time conditions. This dynamic approach allows efficient content distribution while managing complexity through automated, condition-based allocation rather than static configurations.
2Productivity
If functions are distributed over multiple terminals, then execution efficiency and user experience are improved, but the complexity of session management increases
Solution Approach 1:
The patent segments terminal functions into separate functional units that can be independently distributed to different WTRUs. By dividing the terminal's functionality into manageable segments, the system can distribute execution across multiple devices to improve efficiency while reducing the complexity of managing each individual function.
Solution Approach 2:
The patent creates a universal session management framework that can handle multiple functions and devices through a single standardized interface. This multi-functional approach allows efficient distribution of various terminal functions across different WTRUs while simplifying management through a unified, universal control mechanism.
3Adaptability or versatility
If multicast-broadcast traffic is distributed to multiple devices, then content consumption versatility is improved, but network resource utilization becomes more complex
Solution Approach 1:
The patent segments multicast-broadcast traffic into separate logical flows or channels that can be selectively distributed to different WTRUs. This segmentation allows the system to serve multiple devices with different content consumption needs while managing network resources more efficiently by only allocating traffic to active receivers.
Solution Approach 2:
The patent applies local quality optimization by tailoring the distribution of multicast-broadcast traffic to the specific needs of each WTRU. Each device receives customized content based on its capabilities and requirements, improving versatility while optimizing network resource utilization by avoiding unnecessary transmissions to inactive or unsuitable devices.

AI summary
In some cases, various advanced end-user devices, such as wireless transmit receive units (WTRUs), may be used for consuming content (e.g., watching/listening to pre-recorded content, interacting with content or others, watching/listening to live content, data, traffic, etc.). Accordingly, in order to satisfy these new use cases, there may be a single PDU session management procedure(s) that distributes a single PDU session among multiple devices over networks. In some cases, there may be the distribution of functions belonging to a single terminal over multiple terminals thereby improving efficiency of execution and improved user experience.
