A terminal participates in a group call based on a Mission Critical Push to Talk (MCPTT) service. The terminal includes a baseband processor and an application processor. In some embodiments, the baseband processor receives an MCPTT service-related message from outside and determines whether to transmit the MCPTT service-related message to the application processor. The baseband processor may make the determination based on the MCPTT service-related message or based on an operation state of the application processor. As a result of the determining, some embodiments include performing, by at least one of the baseband processor and the application processor, MCPTT service-related operations.

A method for preventing takeoff of a motor velocity of a hybrid electric vehicle, may include checking whether an engine clutch is disengaged while an engine and a motor are simultaneously driven, checking whether a command of motor torque is zero when the engine clutch is disengaged, and checking whether the motor velocity is normal while the command of the motor torque is zero, wherein when the motor velocity abnormally increases as a result of checking whether the motor velocity is normal, the motor torque is corrected to be zero.

Method for preventing takeoff of motor velocity for hybrid electric vehicle

A method of displaying user information of a group including a plurality of terminals, the plurality of terminals including a first terminal manager a floor and a second terminal, the method including transmitting a floor grant message from the first terminal to the plurality of terminals, wherein the floor grant message indicates the second terminal as a transfer target of the floor; acquiring floor candidate information of the second terminal by using a floor request queue; receiving a real-time transport protocol media packet within a predetermined time; determining whether the RTP media packet is from the second terminal; and displaying second terminal user information using the floor candidate information based on a result of the determining.

Method of displaying user information of mission critical push to talk (MCPTT) group performing off-network MCPTT service

A method for controlling a motor based on a variable current controller gain may include a temperature function current applying mode in which when a torque command for the motor is detected by an inverter, 3-phase current to be applied to the motor is output to the motor in consideration of a motor temperature of the motor as a function.
