Edge Application Server Instantiation After Discovery Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge network management systems lack the ability for an Edge Enabler Server (EES) to trigger or request the instantiation of an Edge Application Server (EAS) as a result of failed EAS discovery procedures, requiring interaction with a network management system.
Innovation Solution
The EES is enabled to directly trigger or request EAS instantiation by determining a list of dynamic EAS, modifying the EAS request based on performance measurements, and notifying the ECSP for the need of instantiation using new or existing notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the EES directly triggers or requests EAS instantiation, then the productivity and response time are improved, but the device complexity increases
Solution Approach 1:
The EES performs preliminary actions by maintaining a pre-configured list of potential EAS instances and their capabilities. When discovery is needed, the EES can immediately select and trigger instantiation from this pre-prepared list without requiring complex real-time discovery procedures, thus improving productivity while managing complexity through advance preparation.
Solution Approach 2:
The patent introduces an intermediary mechanism where the EES interacts with a network management system through standardized interfaces. This intermediary approach allows the EES to request EAS instantiation without directly managing the complex instantiation process itself, delegating the complex operations to the network management system while maintaining control and oversight.
2Reliability
If the EES uses performance measurements to determine EAS instantiation, then the reliability is improved, but the measurement precision requirements increase
Solution Approach 1:
The system implements feedback mechanisms where performance measurements of EAS instances are continuously monitored and fed back to the EES. This feedback loop allows the EES to make informed decisions about EAS instantiation based on historical performance data, improving reliability by selecting EAS instances with proven performance rather than relying on single-point measurements that require extreme precision.
Solution Approach 2:
Instead of requiring precise measurements for every possible EAS candidate, the system uses partial evaluation by measuring and comparing only key performance indicators for a subset of potential EAS instances. This approach achieves sufficient reliability for decision-making without demanding excessive measurement precision across all parameters.
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiment herein provide a method performed by a service provider (SP) in an edge network. The method comprises transmitting, to an edge enabler server (EES), a request message for edge application server (EAS) discovery failure performance measurement; receiving, from the EES, a response message including at least one parameter associated with the EAS discovery failure performance measurement; determining whether an instantiation of the EAS is needed or not based on the at least one parameter; and performing instantiation of the EAS in case that the instantiation of the EAS is needed.
