A method, a terminal, and a server for integratedly managing Personal Health Device (PHD) standard and PHD non-standard data are provided. The terminal includes a first sensor for sensing a biological signal, and outputting PHD standard data that is in accordance with predetermined PHD standards; at least one second sensor for sensing a biological signal, and outputting PHD non-standard data that is not in accordance with the predetermined PHD standards; a controller for generating a first data field area based on the PHD standard data, generating a second data field area based on the PHD non-standard data, and then generating a transmission signal including the generated first data field area and the generated second data field area; and a communication unit for receiving the transmission signal from the controller, and transmitting the received transmission signal.
