Abstract

An electronic device includes an information exchange control module configured to receive a first frame from an external electronic device before being connected to the external electronic device. If the first frame received from the external device includes identification information indicating a plurality of electronic devices connected to the external electronic device, transmit, to the external electronic device, a second frame including data information requested to be transmitted from each of the plurality of electronic devices.

First claim

What is claimed is:

1 . An electronic device comprising:
a transceiver; and a processor configured to:
receive, from an access point (AP) supporting Hotspot 2.0, a first frame using the transceiver,
identify whether the first frame includes identification information that identifies a first server and a second server that are wired or wirelessly connected to the AP,
in response to identifying that the first frame includes the identification information, transmit, to the AP using the transceiver, a generic advertisement service (GAS) Request frame including a request for first data information of the first server and second data information of the second server,
receive a response frame from the AP, the response frame including the first data information and the second data information which are received from the first server and second server, respectively, and
connect to the AP based on the response frame.

2 . The electronic device of claim 1 ,
wherein the first frame includes a beacon frame or a probe response frame, and wherein the first data information is information to be used for the electronic device to connect with the AP and the second data information is advertisement information.

3 . The electronic device of claim 2 , wherein the processor is further configured to:
in response to receiving the beacon frame, transmit a probe request frame to the AP using the transceiver, and receive the probe response frame from the AP using the transceiver.

4 . The electronic device of claim 1 , wherein the processor is further configured to include the identification information in the GAS Request frame.

5 . An electronic device supporting Hotspot 2.0, the electronic device comprising:
a transceiver; and a processor configured to:
before connecting to an external electronic device, transmit a first frame to the external electronic device using the transceiver, the first frame including identification information that identifies a first server and a second server that are wired or wirelessly connected to the electronic device,
receive a generic advertisement service (GAS) Request frame from the external electronic device using the transceiver,
based on the receiving of the GAS Request frame, obtain a request for first data information of the first server and second data information of the second server,
request each of the first and second servers to transmit the first data information and second data information, respectively,
transmit a response frame to the external electronic device using the transceiver, the response frame including the first data information which is received from the first server and second data information which is received from the second server, and
connect to the external electronic device.

6 . The electronic device of claim 5 ,
wherein the first frame includes a beacon frame or a probe response frame, and wherein the first data information is information to be used for the external electronic device to connect with the electronic device and the second data information is advertisement information.

7 . The electronic device of claim 5 , wherein, when the GAS Request frame includes the identification information, the processor is further configured to request the first server to transmit the first data information and request the second server to transmit the second data information.

8 . The electronic device of claim 5 , wherein the processor is further configured to:
identify if a storage device includes the first and second data information for the first and second servers, when the storage device does not include the first and second data information, request the first and second servers to transmit the first and second data information, and when the storage device includes the first and second data information for the first and second servers, the processor is further configured to obtain the first and second data information from the storage device.

9 . The electronic device of claim 6 , wherein the processor is further configured to:
in response to transmitting the beacon frame, receive a probe request frame from the external electronic device using the transceiver, and transmit the probe response frame to the external electronic device using the transceiver.

10 . The electronic device of claim 5 , wherein the response frame includes the identification information.

11 . A method for controlling information exchange by an electronic device, the method comprising:
before connecting to an access point (AP) supporting Hotspot 2.0, identifying whether a first frame received from the AP includes identification information that identifies a first server and a second server that are wired or wirelessly connected to the AP; in response to identifying that the first frame includes the identification information, transmitting, to the AP, a generic advertisement service (GAS) Request frame including a request for first data information of the first server and second data information of the second server; receiving a response frame from the AP, the response frame including the first data information and second data information received from the first server and the second server, respectively; and connecting to the AP based on the response frame.

12 . The method of claim 11 ,
wherein the first frame includes a beacon frame or a probe response frame, and wherein the first data information is information to be used for the electronic device to connect with the AP and the second data information is advertisement information.

13 . The method of claim 11 , further comprising:
determining whether the response frame includes the identification information; and when the response frame includes the identification information, obtaining the first data information and second data information from the first server and second server, respectively.

14 . The method of claim 12 , further comprising:
in response to receiving the beacon frame, transmitting a probe request frame to the AP; and receiving the probe response frame from the AP.

15 . The method of claim 11 , wherein the GAS Request frame includes the identification information.

16 . A method for controlling discovery by an electronic device supporting Hotspot 2.0, the method comprising:
before connecting to an external electronic device, transmitting, to the external electronic device, a first frame, the first frame including identification information that identifies a first server and a second server that are wired or wirelessly connected to the electronic device; receiving a generic advertisement request (GAS) Request frame from the external electronic device; based on the receiving of the GAS Request frame, obtaining a request for first data information of the first server and second data information of the second server; in response to the GAS Request frame, requesting each of the first server and second server to transmit the first data information and second data information, respectively; transmitting, to the external electronic device, a response frame including the first data information and second data information which are received from the first server and second server, respectively; and connecting to the external electronic device.

17 . The method of claim 16 ,
wherein the first frame includes a beacon frame or a probe response frame, and wherein the first data information is information to be used for to be used for the external electronic device to connect with the electronic device and the second da
