Edge Configuration Updates via SMS Over NAS for Low-Power UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems supporting edge computing face inefficiencies in managing configuration updates and power consumption for edge data networks, particularly in scenarios involving short message service (SMS) over non-access-stratum (NAS) protocols.
Innovation Solution
A method and device are introduced to facilitate efficient communication in edge computing systems by enabling a user equipment (UE) to identify support for SMS over NAS, transmit provisioning requests to an edge configuration server (ECS), and receive triggering information for configuration updates, thereby optimizing network interactions and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously monitors for configuration updates in edge computing services, then the configuration information remains current, but power consumption increases due to frequent keep-alive operations
Solution Approach 1:
The system implements periodic configuration update notifications where the ECS sends updates at predetermined intervals or when changes occur, rather than requiring continuous UE monitoring. This allows the UE to enter low-power states between periodic updates, significantly reducing power consumption while maintaining configuration currency.
Solution Approach 2:
The UE includes an EEC that automatically manages configuration update subscriptions and processes notifications without requiring manual intervention or continuous active monitoring. The system self-manages the update mechanism, reducing the need for frequent keep-alive operations from the UE side.
2Reliability
If the UE transmits frequent service provisioning requests to ensure configuration updates, then the configuration information remains current, but network interaction overhead increases
Solution Approach 1:
The system implements a feedback mechanism where the ECS notifies the UE of configuration updates through standardized SMS over NAS protocols. This feedback loop ensures the UE receives updates only when necessary, reducing unnecessary network interactions while maintaining configuration accuracy.
Solution Approach 2:
The system changes the notification parameter from frequent UE-initiated requests to ECS-initiated update notifications. This parameter change in the communication pattern reduces network interaction overhead while maintaining configuration update accuracy through event-driven notifications.
3Use of energy by moving object
If the UE supports SMS over NAS protocol for configuration updates, then power consumption is reduced by eliminating keep-alive operations, but compatibility requirements increase
Solution Approach 1:
The system implements SMS over NAS protocol which serves multiple functions: it carries both configuration update notifications and triggering information for service provisioning requests. This multi-functional approach reduces the need for separate keep-alive operations while maintaining broad compatibility across different edge computing service scenarios.

AI summary
A communication method and device in a wireless communication system supporting edge computing is provided. A method of a UE including an EEC in a communication system supporting an edge computing service using an EDN exchanging application data traffic with the UE is provided, the method comprises identifying whether the UE supports a SMS over NAS, transmitting, to an ECS managing configuration information of the EDN, a first service provisioning request message including an indication of the SMS over the NAS supported in case that the UE supports the SMS over the NAS, and in case that the UE receives, through a network from the ECS, an SMS message including triggering information related to an update of the configuration information, transmitting, to the ECS, a second service provisioning request message based on the triggering information.
