Abstract

A display device includes a display; a memory storing at least one instruction; a communicator configured to communicate with a mobile device via a BLE communication network; and a controller including a processor configured to execute the at least one instruction stored in the memory. The processor is further configured to execute the at least one instruction to manage BLE identification information when the BLE identification information for identifying the mobile device connected via the BLE communication network is received from the mobile device during a normal mode in which an ambient service is being executed, and the communicator is further configured to, based on the BLE identification information received from the mobile device after a sleep mode is started, determine whether to wake up the controller based on whether information corresponding to the BLE identification information is stored in the communicator.

First claim

What is claimed is:

1. A display device comprising:
a display;
a memory storing at least one instruction;
a communicator configured to communicate with a mobile device via at least one wireless network comprising a Bluetooth low energy (BLE) communication network; and
a controller comprising at least one processor configured to execute the at least one instruction to:
control identification information of a registered mobile device to be respectively stored in both the memory and a dedicated memory for the communicator that is different from the memory;
set a scheme to obtain BLE identification information for identifying the mobile device, according to a type of operating system (OS) of the registered mobile device;
in response to an OS of the registered mobile device being a first OS, control the communicator to be in a state in which the communicator waits to receive a signal transmitted from the mobile device, to obtain BLE identification information;
in response to an OS of the registered mobile device being a second OS different from the first OS, control the communicator to: transmit, a first signal for requesting transmission of the BLE identification information to the mobile device, and to be in a state in which the communicator waits to receive a signal transmitted from the mobile device in response to the first signal, to obtain the BLE identification; and
in response to the BLE identification information being obtained by the communicator while the display device operates in a normal mode in which a service for displaying a screen image on the display is being executed, determine whether to maintain the executing of the service based on whether the identification information corresponding to the BLE identification information is stored in the memory.

2. The display device of claim 1 , wherein the first OS is an Android OS and the second OS is an iOS.

3. The display device of claim 2 , wherein the OS of the registered mobile device is the first OS, and
the at least one processor is further configured to execute the at least one instruction to control the communicator to perform a scanning operation by periodically checking reception of the signal including the BLE identification information at a first time intervals.

4. The display device of claim 2 , wherein the OS of the registered mobile device is the first OS, and
the at least one processor is further configured to execute the at least one instruction to control the communicator to be in a state in which the communicator performs a scanning operation to obtain the BLE identification information transmitted from the mobile device.

5. The display device of claim 2 , wherein the OS of the registered mobile device is the second OS, and
the at least one processor is further configured to execute the at least one instruction to:
control the communicator to transmit, at a second time intervals, a first iBeacon signal as the first signal to the mobile device, and to perform a scanning operation by checking reception of a second iBeacon signal including the BLE identification information, triggered by the first iBeacon signal.

6. The display device of claim 1 , wherein the communicator is further configured to:
in response to the BLE identification information being obtained by the communicator while the display device operates in a sleep mode, determine whether to wake up the controller based on whether the identification information corresponding to the BLE identification information obtained by a scanning operation is stored in the dedicated memory for the communicator.

7. The display device of claim 6 , wherein the communicator is further configured to wake up the controller based on the identification information corresponding to the BLE identification information being present in the dedicated memory.

8. The display device of claim 6 , wherein the communicator is further configured to maintain the sleep mode of the controller based on the identification information corresponding to the BLE identification information not being present in the dedicated memory.

9. The display device of claim 1 , wherein the BLE identification information comprises a BLE media access control (MAC) address of the mobile device or a random address of the mobile device, the random address being convertible to the BLE MAC address by using an Identity Resolving Key (IRK).

10. A method for operating a display device comprising a communicator configured to communicate with a mobile device via at least one wireless network comprising a Bluetooth low energy (BLE) communication network, and a controller, the method comprising:
controlling, by the controller, identification information of a registered mobile device to be respectively stored in both the memory and a dedicated memory for the communicator that is different from the memory;
setting a scheme to obtain BLE identification information for identifying the mobile device, according to a type of operating system (OS) of the registered mobile device;
in response to an OS of the registered mobile device being a first OS, controlling the communicator to be in a state in which the communicator waits to receive a signal transmitted from the mobile device, to obtain BLE identification information;
in response to an OS of the registered mobile device being a second OS different from the first OS, controlling the communicator to: transmit, a first signal for requesting transmission of the BLE identification information to the mobile device, and to be in a state in which the communicator waits to receive a signal transmitted from the mobile device in response to the first signal, to obtain the BLE identification information; and
in response to the BLE identification information being obtained by the communicator while the display device operates in a normal mode in which a service for displaying a screen image on the display is being executed, determining whether to maintain the executing of the service based on whether the identification information corresponding to the BLE identification information is stored in the memory.

11. The method of claim 10 , wherein the first OS is an Android OS and the second OS is an iOS.

12. The method of claim 11 , wherein the OS of the registered mobile device is the first OS, and
the method further comprises:
controlling the communicator to perform a scanning operation by periodically checking reception of the signal including the BLE identification information at a first time intervals.

13. The method of claim 11 , wherein the OS of the registered mobile device is the first OS, and
the method further comprises:
controlling the communicator to be in a state in which the communicator performs a scanning operation to obtain the BLE identification information transmitted from the mobile device.

14. The method of claim 11 , wherein the OS of the registered mobile device is the second OS, and
the method further comprises:
controlling the communicator to transmit, at a second time intervals, a first iBeacon signal as the first signal to the mobile device, and to perform a scanning operation by checking reception of a second iBeacon signal including the BLE identification information, triggered by the first iBeacon signal.

15. The method of claim 10 , wherein the method further comprises:
in response to the BLE identification information being obtained by the communicator while the display device operates in a sleep mode, determining, by the communicator, whether to wake up the controller based on whether the identification information corresponding to the BLE identification informa
