Edge Cloud Gateway for Precise MEC Node Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to accurately schedule mobile terminals to the closest mobile edge computing (MEC) node in 5G mobile communication networks, resulting in low precision and inability to meet the high requirements for processing and transmission rates.
Innovation Solution
A method and system that utilizes an edge cloud gateway, integrated with a user plane function and global server load balance, to select an MEC node by processing domain name requests, obtaining edge-application virtual IPs, and routing service requests to the nearest MEC processing server, compatible with both standard DNS and HTTP DNS addressing scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional technology is used for MEC node selection, then network compatibility is maintained, but selection precision and latency reduction are insufficient
Solution Approach 1:
The patent introduces a domain name translation intermediary mechanism between the terminal and MEC processing server. The terminal translates the MEC processing server address to a domain name, which is then translated back to an IP address through domain name translation. This intermediary approach enables precise MEC node selection without requiring direct complex addressing, thus improving selection precision while maintaining manageable system complexity.
2Speed
If the terminal directly connects to the MEC processing server using IP address, then connection speed is fast, but selection accuracy of the nearest node is low
Solution Approach 1:
The patent implements preliminary domain name translation before the terminal establishes a connection to the MEC processing server. The address translation from IP to domain name and back to IP address occurs in advance through the domain name translation mechanism, enabling the terminal to select the nearest MEC node accurately before connection is established, thus maintaining fast connection speed while improving node selection accuracy.
3Adaptability or versatility
If standard DNS protocol is used for domain name resolution, then compatibility with existing network infrastructure is maintained, but service acceleration capability is limited
Solution Approach 1:
The patent implements a multi-functional domain_name translation mechanism that handles both standard DNS resolution and service acceleration requirements. The system can translate domain names to IP addresses for standard network compatibility while also supporting service acceleration by translating to addresses of nearby MEC processing servers. This universal mechanism maintains network compatibility while enabling service acceleration, thus resolving the contradiction between adaptability and productivity.

AI summary
The present application relates to the field of mobile communications, and in particular, to a method, device, and system for selecting a mobile edge computing node. The method comprises: an edge cloud gateway receives a domain name request forwarded by a user plane function, wherein in the domain name request, the domain name is a service acceleration domain name or a destination address is an IP address of a global server load balancer, or protocol port information in the domain name request satisfies a protocol port requirement; obtain a corresponding edge application VIP from the global server load balancer and send same to a terminal by means of the user plane function; receive a service request sent by the terminal and forwarded by the user plane function; shunt the service request to a corresponding MED processing server. The present application newly adds an edge cloud gateway, is compatible with both DNS and HTTP DNS addressing scenes, and achieves the purpose of selecting a nearest edge computing node to implement edge acceleration.
