A wireless communication method supporting a Rich Communication Suite (RCS) service, the method including performing an RCS provision operation corresponding to an Original Equipment Manufacturer (OEM) application in response to an RCS service request of the OEM application, transmitting an RCS function connection request to a Session Initiation Protocol (SIP) transport layer after the RCS provision operation is completed, controlling a session for an RCS function based on the RCS function connection request to obtain a dedicated bearer, and exchanging RCS media data with a network through the dedicated bearer.

Wireless communication apparatus supporting rich communication suite (RCS) and wireless communication method thereof

A user log information output system includes a first user device configured to generate first user information by encrypting a unique identification (ID) of a first user according to a scheduled time; a first user server configured to generate first server information including a server group code of a hierarchical server group; a second user device configured to receive real-time token information through communication with the first user device, the real-time token information being generated based on the first user information and the first server information; and a second user server configured to generate proximity log information regarding the first user by reading the first user information and the first server information of the real-time token information received from the real-time token information from the second user device.

User state tracking system and operating method thereof

A method of performing wireless communication for a wireless communication device including a first Subscriber Identity Module (SIM) and a second SIM includes performing a first wireless communication with a first terminal device through the first SIM, receiving a request for connection of a second wireless communication from a second terminal device through the second SIM, determining a target SIM among the first SIM and the second SIM in response to the request, and performing the first wireless communication and the second wireless communication through the target SIM.
