TECHNICAL FIELD

The disclosure relates to a method and an apparatus for enabling a user to control a vehicle using a terminal as a smart key for the vehicle.

BACKGROUND ART

To meet the increasing demand for wireless data traffic since the deployment of 4G communication systems, efforts have been made to develop an improved 5G or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called a “beyond 4G network” communication system or a “post LTE System.” Implementation of the 5G communication system in ultrahigh frequency (mmWave) bands, e.g., 60 GHz bands, is being considered in order to accomplish higher data rates. To mitigate a path loss of the radio waves and increase the transmission distance on the radio waves in the ultrahigh frequency bands, beamforming, massive multiple-input multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large scale antenna techniques are being discussed for 5G communication systems. In addition, in 5G communication systems, development for system network improvement is under way based on evolved small cells, advanced small cells, cloud radio access networks (cloud RANs), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, moving network, cooperative communication, coordinated multi-points (CoMP), reception-end interference cancellation, and the like. In addition, in the 5G communication system, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC), as advanced coding modulation (ACM) systems, and filter bank multi carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA), as advanced access technologies, have been developed.

On the other hand, the Internet, which is a human centered connectivity network where humans generate and consume information, is now evolving to the Internet of things (IoT) where distributed entities, such as things, exchange and process information without human intervention. The Internet of everything (IoE) technology, which is a combination of IoT technology and big data processing technology through connection with a cloud server, has emerged. Technology elements, such as “sensing technology”, “wired/wireless communication and network infrastructure”, “service interface technology”, and “security technology” have been demanded for IoT implementation; therefore, technologies, such as a sensor network, machine-to-machine (M2M) communication, machine type communication (MTC) for a connection between things, are recently researched.

Such an IoT environment may provide intelligent Internet technology (IT) services that create a new value for human life by collecting and analyzing data generated among connected things. IoT may be applied to a variety of fields including smart home, smart building, smart city, smart car or connected car, smart grid, health care, smart appliances, and advanced medical services through convergence and combination between existing information technology (IT) and various industrial applications.

In line with this, various attempts have been made to apply 5G communication systems to IoT networks. For example, technologies such as a sensor network, machine-to-machine (M2M) communication, and machine type communication (MTC) may be implemented by techniques of beamforming, MIMO, and array antennas, which correspond to 5G communication technologies. As the big data processing technology as described above, a cloud radio access network (cloud RAN) may be applied as an example of convergence of 5G technology and IoT technology.

In general, in order to control open/close of a vehicle door and to start a vehicle, a smart key having predetermined size and volume has been generally used. There have been increasing needs for a user to control various devices, such as a home system, home appliances, or other electronic devices.

Accordingly, the necessity of a technology to use a user's terminal as a smart key for a vehicle has been on the rise.
