Wireless Split Computing QoS Provisioning for Reliable AI/ML
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in providing efficient split computing services due to the lack of information about variations in network and communication resources, which can lead to deteriorated performance or non-operation of split computing services, particularly for AI/ML applications.
Innovation Solution
A method and device are provided to manage and distribute computing loads between an application server and user equipment (UE) by transmitting quality of service (QoS) related information via a session management function (SMF) in a wireless communication system, using network entities like PCF or UDM, to support split computing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If split computing service is provided without QoS information transmission, then device complexity is reduced, but reliability of split computing service deteriorates
Solution Approach 1:
The patent applies preliminary action by transmitting QoS information during the session establishment procedure, before the split computing service actually operates. The SMF proactively provides QoS parameters to the UE in advance (in operation 503 of Fig. 5), so that when the split computing service runs, the UE already has the necessary resource allocation information to ensure reliable operation without needing complex real-time QoS negotiation mechanisms.
2Reliability
If QoS information is transmitted during session establishment, then reliability of split computing service is improved, but loss of time in session establishment procedure increases
Solution Approach 1:
The patent merges the QoS information transmission with the existing session establishment procedure. Instead of adding a separate QoS negotiation phase that would extend the establishment time, the SMF includes QoS information in the messages already exchanged during session establishment (PDU session establishment request/response messages). This combines two functions into one process, improving reliability without significantly increasing time loss.
3Productivity
If detailed QoS information is provided to UE, then productivity of split computing is improved, but device complexity for processing QoS information increases
Solution Approach 1:
The patent extracts only the essential QoS parameters needed for split computing operation and transmits them to the UE, rather than providing complete detailed QoS information. The SMF identifies and sends specific parameters (such as resource allocation indicators, QoS profiles) that are sufficient for the UE to adjust its computing operations, removing unnecessary complexity while maintaining productivity benefits.
