Method and apparatus for performing object transfer service using bluetooth low energy in wireless communication system

A client device performing communication with a server device using Bluetooth low energy (BLE) in a wireless communication system, the client device comprising:

• a communication unit configured to perform communication with an outside in a wireless or wired manner;
• and
• a processor operatively connected to the communication unit,
• wherein the processor controls the communication unit so that the communication unit receives an advertising message transmitted from the server device to establish a connection with a nearby device, the advertising message including object transfer service-related information,
• controls the communication unit so that the communication unit sends a scan request message tor obtaining additional information to the server device and receives a scan response message from the server device as a response to the scan request,
• controls the communication unit so that the communication unit sends a connect request message to the server device in order to establish a Bluetooth communication connection with the server device,
• controls the communication unit so that the communication unit receives, from the server device, object changed indication information comprising an identifier (ID) of an object that is changed and generation flag information indicating whether a new object or data has been created, when the change of the object is generated in the service device, and
• controls the communication unit so that the communication unit transmits an object list control point (OLCP) including an operation code (Op Code) indicating an operation of designating an object having a specific object ID as a current object in an object list of the server device.

A method for performing communication using Bluetooth low energy (BLE) in a wireless communication system comprising a server device and a client device, the method performed by the server device and comprising:

• transmitting an advertising message to establish a connection with a nearby device,
• wherein the advertising message includes object transfer service-related information;
• receiving a scan request message for obtaining additional information from the client device;
• transmitting a scan response message to the client device as a response to the scan request;
• receiving a connect request message from the client device in order to establish a Bluetooth communication connection with the client device;
• transmitting, to the client device, object changed indication information comprising an identifier (ID) of an object that is changed and generation flag, information indicating whether a new object or data has been created, when the change of the object is generated in the server device;
• and
• receiving an object list control point (OLCP) including an operation code (Op Code) indicating an operation of designating an object having a specific object ID as a current object in an object list of the server device.
