## Abstract

An electronic device is provided. The electronic device includes a communication circuit for performing first communication and second communication, an entry-exit management circuit for controlling a door locking device, and a processor operatively connected to the communication circuit and the entry-exit management circuit. The processor establishes a connection to an external electronic device by using the first communication, transmit or receive a parameter for the second communication by using the first communication, establish a connection to the external electronic device by using the second communication, measure the distance from the external electronic device by using a first mode of the second communication, identify a key stored in the external electronic device when the measured distance is within a designated distance, activate or deactivate the door locking device by using the entry-exit management circuit on the basis of the key, and determine whether a first distance from a user of the external electronic device or a second distance from the external device is measured, on the basis of at least one of a state of the external electronic device, the first distance, and the second distance when the door locking device is deactivated, wherein the first distance may be measured using a second mode of the second communication.

## Claims

### Claim 1

An electronic device comprising:
a communication circuit configured to perform a first communication and a second communication;
an access management circuit configured to control a door locking device; and
a processor operatively connected to the communication circuit and the access management circuit,
wherein the processor is configured to:
establish a connection to an external electronic device by using the first communication,
transmit or receive a parameter for the second communication by using the first communication,
establish a connection to the external electronic device by using the second communication,
measure a distance from the external electronic device by using a first mode of the second communication,
identify a key stored in the external electronic device in case that the measured distance is within a designated distance,
activate or deactivate, based on the key, the door locking device by using the access management circuit, and
when the door locking device is deactivated, determine whether a first distance from a user of the external electronic device or a second distance from an external device is measured, based on at least one of a state of the external electronic device, the first distance, or the second distance, and
wherein the first distance is measured using a second mode of the second communication.

### Claim 2 (depends on 1)

The electronic device of claim 1,
wherein the first communication is Bluetooth communication, and
wherein the second communication is ultra-wide band (UWB) communication.

### Claim 3 (depends on 2)

The electronic device of claim 2, wherein the parameter required for the second communication comprises:
a channel,
a preamble duration,
a pulse repetition frequency,
a preamble code, and
whether the communication is secure or non-secure.

### Claim 4 (depends on 2)

The electronic device of claim 2, wherein the first mode is a UWB positioning mode, and the second mode is a radar mode.

### Claim 5 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to determine, by measuring an angle of arrival (AOA), whether the user of the external electronic device has entered an authorized zone.

### Claim 6 (depends on 1)

The electronic device of claim 1, wherein the state of the external electronic device is determined using a sensor included in the external electronic device.

### Claim 7 (depends on 1)

The electronic device of claim 1, wherein the key is configured differently according to at least one of a time during which access to an authorized zone is authorized and a range of the authorized zone.

### Claim 8 (depends on 1)

The electronic device of claim 1, further comprising a speaker,
wherein the processor is configured to:
when the door locking device is deactivated, configure a timer; and
provide a warning by using the speaker in case that it is determined that the measured distance from the user of the external electronic device or the measured distance from the external electronic device is greater than a determined value or the configured timer expires.

### Claim 9 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to disconnect the connection with the first communication in case that a connection is established to the external electronic device by using the second communication.

### Claim 10 (depends on 1)

The electronic device of claim 1, wherein at least one of a specific area and an authorized zone is configured by an administrator of the electronic device.
