MEC Control Server Service Recommendation for 5G Local Area Data Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demands for advanced communication systems, particularly in 5G networks, require efficient methods to provide local services that meet the needs of enhanced mobile broadband, massive machine-type communication, and ultra-reliable and low-latency communication environments, which existing technologies struggle to address effectively.
Innovation Solution
The implementation of a mobile edge computing (MEC) control server that determines and recommends services to user equipment (UE) based on location and behavior patterns, utilizing a local area data network (LADN) to reduce latency and congestion by providing services closer to the UE, such as food ordering, ticket buying, and video caching, through MEC servers located within the LADN.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If services are provided through the core network in traditional mobile networks, then network coverage and service availability are maintained, but latency increases and network congestion occurs
Solution Approach 1:
The patent segments the service delivery function by separating it from the core network and deploying MEC servers at the network edge. This segmentation allows local services to be provided without routing traffic through the core network, thereby reducing latency while maintaining service availability through distributed service delivery points
Solution Approach 2:
The patent introduces an intermediary mechanism (MEC control server and MEC servers) between the user equipment and the core network. This intermediary enables local service provisioning at the network edge, reducing the need for core network traversal and thereby reducing latency while maintaining reliable service delivery
2Ease of operation
If services are provided through the core network, then centralized service management is achieved, but network congestion increases and response time decreases
Solution Approach 1:
The patent segments service management into two parts: centralized control through the MEC control server and distributed service delivery through MEC servers. This segmentation maintains ease of operation through centralized management while improving network efficiency by localizing service delivery and reducing core network traffic
Solution Approach 2:
The patent adds a spatial dimension to service delivery by deploying MEC servers at multiple edge locations throughout the network. This dimensional change allows services to be delivered locally without compromising centralized management capabilities, thereby improving network efficiency while maintaining ease of operation
3Loss of time
If MEC servers are deployed at the network edge, then latency is reduced and local services are improved, but device complexity and deployment cost increase
Solution Approach 1:
The patent designs MEC servers with multi-functionality, enabling them to provide various local services (content delivery, computing, storage, etc.) from a single deployment. This universality reduces device complexity by consolidating multiple service functions into standardized MEC server units rather than requiring separate specialized devices for each service type

AI summary
A method and an apparatus for recommending a service provided by a local area data network (LADN) are provided. The operation method of a mobile edge computing (MEC) control server includes receiving, from at least one of a user equipment (UE), an access and mobility management function (AMF) device, or a session management function (SMF) device, location information including a cell identity (ID) of a cell to which the UE is connected or a tracking area identity (TAI) of a tracking area in which the UE is located, determining at least one LADN accessible by the UE, based on the location information, determining a first service to be recommended to the UE from among services providable to the UE through the at least one LADN, and transmitting, to the UE, information associated with the recommended first service and a LADN capable of providing the recommended first service.
