Description

Method and apparatus for providing Internet of Things services in an Internet of Things system supporting multi-manager services Method and apparatus for providing Internet of Things services in an Internet of Things system supporting multi-manager services The present disclosure relates to a method and apparatus for providing a communication service for the use of an IoT device in an IoT (Internet of Things) system. The Internet is evolving from a human-centered network where humans generate and consume information into an IoT (Internet of Things) network where distributed components, such as objects, exchange and process information. IoE (Internet of Everything) technology, which combines IoT with Big Data processing technologies through connections with cloud servers, is also emerging. Implementing IoT requires technological elements such as sensing technology, wired and wireless communication and network infrastructure, service interface technology, and security technology. Recently, technologies such as sensor networks, Machine-to-Machine (M2M) communication, and Machine-Type Communication (MTC) are being researched for connecting objects. In an IoT environment, intelligent IT (Internet Technology) services that create new value for human life by collecting and analyzing data generated from connected objects can be provided. Through the convergence and integration of existing IT (Information Technology) with various industries, IoT can be applied to fields such as smart homes, smart buildings, smart cities, smart or connected cars, smart grids, healthcare, smart home appliances, and advanced medical services. In addition, various wireless communication technologies are being developed alongside the recent advancement of information and communication technology.
