Electronic device and method for providing notification service therefor

1. An electronic device for providing a plurality of notification services, the electronic device comprising:

a communication unit comprising a communication circuit; and

a processor configured to:

based on interest information of a user and system information being received from an external device of a user via the communication unit, identify a first matching degree between the interest information and first information included in notification service information of the plurality of notification services, and identify a second matching degree between the system information and second information included in the notification service information of the plurality of notification services;

based on the first matching degree and the second matching degree, register the user for a notification service from among the plurality of notification services; and

control the communication unit to transmit a message for providing the notification service to the external device corresponding to the registered user,

wherein the system information comprises at least one of location information of the external device or device specification information of the external device.

2. The electronic device as claimed in claim 1 , wherein the processor is configured to:

register the user for the notification service in which the first matching degree is equal to or greater than a first threshold value, and the second matching degree is equal to or greater than a second threshold value, from among the plurality of notification services, and

wherein the first threshold value is greater than the second threshold value.

3. The electronic device as claimed in claim 2 , wherein the processor is configured to:

register the user for the notification service in which the first matching degree is equal to or greater than a third threshold value less than the first threshold value, and the second matching degree is equal to or greater than a fourth threshold value less than the second threshold value, from among the plurality of notification services, and

wherein the third threshold value is greater than the fourth threshold value.

4. A method for controlling an electronic device for providing a plurality of notification services, the method comprising:

receiving, from an external device of a user, interest information of the user and system information of the external device;

identifying a first matching degree between the interest information and first information included in notification service information of the plurality of notification services, and identifying a second matching degree between the system information and second information included in the notification service information of the plurality of notification services;

based on the first matching degree and the second matching degree, registering the user for a notification service from among the plurality of notification services; and

transmitting a message for providing the notification service to the external device corresponding to the registered user,

wherein the system information comprises at least one of location information of the external device or device specification information of the external device.

5. The method as claimed in claim 4 , wherein the registering comprises registering the user for the notification service in which the first matching degree is equal to or greater than a first threshold value, and the second matching degree is equal to or greater than a second threshold value, from among the plurality of notification services, and

wherein the first threshold value is greater than the second threshold value.

6. The method as claimed in claim 5 , wherein the registering comprises registering the user for the notification service in which the first matching degree is equal to or greater than a third threshold value less than the first threshold value, and the second matching degree is equal to or greater than a fourth threshold value less than the second threshold value, from among the plurality of notification services, and

wherein the third threshold value is greater than the fourth threshold value.

7. A system comprising:

a first electronic device comprising a first communication unit a user interface configured to receive interest information of a user, and a first processor configured to control the first communication unit to transmit the interest information and system information of the first electronic device, the system information of the first electronic device comprising at least one of location information of the first electronic device or device specification information of the first electronic device; and

a plurality of second electronic devices, each respective second electronic device providing a notification service and comprising:

a second communication unit including a communication circuit; and

a second processor configured to:

based on the interest information and system information of the first electronic device being received from the first electronic device via the second communication unit, identify a first matching degree between the interest information and first information included in notification service information of the plurality of notification services, and identify a second matching degree between the system information and second information included in the notification service information of the plurality of notification services;

based on the first matching degree and the second matching degree, register the user for a notification service from among the plurality of notification services, and

control to transmit, via the communication unit, a message for providing the notification service to the first electronic device corresponding to the registered user.

8. The system as claimed in claim 7 , wherein the first electronic device and the plurality of second electronic devices are Internet of Things (IoT) devices.
