BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a method and apparatus for identifying a service entity in an Machine-to-Machine (M2M) system. More particularly, the present invention relates to a method and apparatus for identifying a service entity that provides a suitable service for an application in an M2M system.

Description of the Related Art

Recently, introduction of Machine-to-Machine (M2M) system has become active. An M2M communication may refer to a communication carried out between machines without human intervention. M2M may refer to Machine Type Communication (MTC), Internet of Things (IoT) or Device-to-Device (D2D). In the following description, the term “M2M” is uniformly used for convenience of explanation, but the present invention is not limited thereto. A terminal used for M2M communication may be an M2M terminal or an M2M device. An M2M terminal may generally be a device having low mobility while transmitting a small amount of data. Herein, the M2M terminal may be used in connection with an M2M server that centrally stores and manages inter-machine communication information.

In addition, an M2M terminal may be applied to various systems such as object tracking, automobile linkage, and power metering.

Meanwhile, with respect to an M2M terminal, the oneM2M standardization organization provides requirements for M2M communication, things to things communication and IoT technology, and technologies for architecture, Application Program Interface (API) specifications, security solutions and interoperability. The specifications of the oneM2M standardization organization provide a framework to support a variety of applications and services such as smart cities, smart grids, connected cars, home automation, security and health.

SUMMARY OF THE INVENTION

The present invention aims to provide a method and device for identifying a service entity rendering a suitable service in an Machine-to-Machine (M2M) system.
