Description

MEC platform, digital twin service system with it, and its operation method {MULTI-ACCESS OR MOBILE EDGE COMPUTING PLATFORM, DIGITAL TWIN SERVICE SYSTEM HAVING THE SAME AND OPERATING METHOD THEREOF}

The present invention relates to a MEC platform, a digital twin service system having the same, and a method of operation thereof.

In general, in developing a MEC application to be operated on a multi-access or mobile edge computing (MEC) platform in a 5G mobile communication environment, the MEC application needs to acquire information on a terminal and a communication network providing a service. This is because a strategy such as providing a service with a better quality to a specific terminal and providing a service module with a small required bandwidth (eg, a low-quality video) according to the state of the communication network can be executed. In the ETSI (European Telecommunications Standards Institute) MEC standard, four service standards are standardized as a method for MEC applications to acquire information from the MEC platform, which are Radio Network Information (radio access information), API (Application Programming Interface), and Location. These are (terminal location) API, User Equipment Identity (subscriber information) API, and Bandwidth Management (bandwidth management information) API. However, since the service is in a REST API method that responds to the request during execution of the MEC application, there is a problem that the MEC application development is complicated. For example, when trying to develop a MEC application that informs each terminal of the other party's information when the location of two different terminals approaches within a certain range, the current method is that the MEC application is used through the MEC platform's Location API. The process of acquiring the location information of the terminal, calculating the distance, and determining whether it has approached within a certain range should be performed periodically. In addition, when the location information of the same terminal is to be used in different MEC applications, the location information of the same terminal must be acquired and managed for each MEC application, resulting in inefficiency of MEC platform resources. Therefore, there is a need for a method to increase the efficiency of MEC application development and resource utilization.

In the general 4G LTE mobile communication environment, the smartphone was the only mobile communication terminal, but in the 5G mobile communication environment, which is about to be commercialized worldwide, not only smartphones, but also various types of terminals such as connected cars, medical devices, robots, drones, and various meter reading sensors. You are connected to this mobile communication network. In this environment, three service scenarios are possible according to the type of terminal, the characteristics of the service, and the required quality. The three service scenarios are eMBB (enhanced mobile broadband), which provides high-quality services based on improved data transmission speed, using multimedia services used in existing smartphones, and mMTC (massive MTC) that supports multiple MTC (Machine Type Communication) terminals. ), and supports high-reliability/ultra-low delay communication to support scenarios that can cause fatal loss such as human life or property damage when communication delays or errors occur during service such as industrial automation, medical robot control, autonomous driving, and augmented reality. This is URLLC (Ultra Reliable and Low Latency Communication).

Among the scenarios, URLLC is a problem when there is a network delay between the terminal and the service.In the existing mobile communication network structure, the terminal's service request is transmitted to the Internet through the base station and the core network of the mobile operator, and through the service cloud on the Internet. A certain level of delay cannot be avoided since the processed result is returned to the terminal through the network of the communication company. In response to this, the European Telecommunication Standards Institute (ETSI) has adopted multi-access (or mobile) edge computing (MEC) technology to resolve service delays and bottlenecks in the core network. Korean standards (hereinafter referred to as ETSI MEC standards) are being developed. The MEC platform defined in the ETSI MEC standard deploys services and contents of the cloud existing on the wired core network and the Internet in a location close to the 5G mobile communication terminal (depending on the policies of mobile carriers such as base stations, centralized stations, and switching centers).
