Methods for supporting connection between devices serving on different channels and device thereof
The present disclosure provides a method for supporting a connection between devices serving on different channels, and a device serving on a first channel and supporting connection with a counterpart device serving on a second channel different from the first channel. The device includes a transceiver and a processor configured to control the transceiver. The processor is configured to broadcast a first beacon frame over the first channel, to generate a second beacon frame including information on the first channel, and to broadcast the second beacon frame over the second channel.
1. A method for a device serving on a first channel to connect itself with a counterpart device serving on a channel different from the first channel, the method comprising:
broadcasting a first beacon frame over the first channel;
generating a second beacon frame including information on the first channel; and
broadcasting the second beacon frame over each of second channels that are different from the first channel,
wherein the first beacon frame is broadcasted when a current beacon time is within a first time section, and the second beacon frame is broadcasted when the current beacon time is within a second time section that is different from the first time section;
wherein the second time section is set for each of the second channels, thereby allowing the second beacon frame to be transmitted to different second channels at different beacon times;
wherein for each of the second channels, the second beacon frame is repeatedly broadcasted at a corresponding time interval;
wherein generating of the second beacon frame comprises adding a channel switch information element to the first beacon frame; and
wherein the second beacon frame Includes information used for establishing connection between the device and the counterpart device after the counterpart device switching to the first channel.
2. The method of claim 1 , wherein the second beacon frame includes an information element that includes instructions for the counterpart device which received the second beacon frame over any one of the second channels to switch itself to the first channel.
3. The method of claim 2 , further comprising:
establishing a connection with the counterpart device on the first channel.
4. The method of claim 1 , wherein the first time section is set based on a transmission time of a delivery traffic indication map (DTIM).
5. A device serving on a first channel and supporting connection with a counterpart device serving on a channel different from the first channel, the device comprising:
a transceiver and a processor configured to control the transceiver,
wherein the processor is configured
to broadcast a first beacon frame over the first channel,
to generate a second beacon frame including information on the first channel, and
to broadcast the second beacon frame over each of second channels that are different from the first channel,
wherein the first beacon frame is broadcasted when a current beacon time is within a first time section, and the second beacon frame is broadcasted when the current beacon time is within a second time section that is different from the first time section;
wherein the second time section is set for each of the second channels, thereby allowing the second beacon frame to be transmitted to different second channels at different beacon times,
wherein for each of the second channels, the second beacon frame is repeatedly broadcasted at a corresponding time interval;
wherein generating of the second beacon frame comprises adding a channel switch information element to the first beacon frame; and
wherein the second beacon frame includes information used for establishing connection between the device and the counterpart device after the counterpart device switching to the first channel.
6. The device of claim 5 , wherein the second beacon frame includes an information element that includes instructions for the counterpart device which receives the second beacon frame over any one of the second channels to switch itself to the first channel.
7. The device of claim 6 , wherein the processor is configured to establish a connection with the counterpart device on the first channel in response to the second beacon frame.
8. The device of claim 5 , wherein the first time section is set based on a transmission time of a delivery traffic indication map (DTIM).
