Abstract

An example embodiment enables wireless devices to adapt their channel maps when initiating connection to avoid interference, comprising receiving, by an apparatus, wireless device discovery messages from one or more other wireless devices in wireless networks not connected to the apparatus, one or more of the received wireless discovery messages including channel information indicating status of one or more channels; creating, by the apparatus, a channel map that is at least partly based on the status of the one more channels indicated in the received one or more wireless device discovery messages; and selecting, by the apparatus, channels for setting up wireless communication with another wireless device, the channels being selected at least partly based on the channel map created by the apparatus.

Claims

1. A method, comprising:

receiving, by an apparatus, wireless device discovery messages from one or more other wireless devices in wireless networks not connected to the apparatus, one or more of the received wireless discovery messages including channel information indicating status of one or more channels;

creating, by the apparatus, a channel map that is at least partly based on the status of the one more channels indicated in the received one or more wireless device discovery messages; and

selecting, by the apparatus, channels for setting up wireless communication with another wireless device, the channels being selected at least partly based on the channel map created by the apparatus.

2. The method of claim 1, further comprising:

receiving, by the apparatus, second wireless device discovery messages from the one or more other wireless devices in the wireless networks not connected to the apparatus, one or more of the received wireless discovery messages including channel information indicating a change in status of one or more channels;

creating, by the apparatus, a second channel map that is at least partly based on the change in status of the one more channels; and

tuning, by the apparatus, channels for continued communication over an existing wireless connection with the another wireless device, the channels being tuned based on the second channel map created by the apparatus.

3. The method of claim 1, wherein the channel information in the received wireless discovery message comprises at least one of a bit mask of used channels, a bit mask of used channels where a last several bits are used to indicate channel occupancy rate, and predefined used channel sets.

4. The method of claim 1, wherein the wireless device discovery messages received by the apparatus are Bluetooth Low Energy advertising messages and the channel information included in the advertising messages is a channel map indicating wireless channels in use by the one of the one or more other wireless devices that sent the received advertising messages, the channel map further indicating one or more wireless channels having interference.

5. The method of claim 1, wherein the creating, by the apparatus, of a channel map is performed by creating a new channel map of the apparatus using an LE Set Host Channel Classification Command, to specify a channel classification based on channels indicated in the received wireless device discovery messages.

16. The method of claim 1, wherein the channel information indicates a subset of channels used by the one or more other wireless devices, and channels that are not members of the subset, which are not used by the one or more other wireless devices, but the channel information does not indicate unused channels that are unsuitable for use.

17. The method of claim 1, wherein the channel information indicates a subset of channels used by the one or more other wireless devices, channels that are not members of the subset, which are suitable for use but are not used by the one or more other wireless devices, and channels that are unsuitable for use.

18. The method of claim 1, wherein the channel information indicates channels that are unsuitable for use.

19. The method of claim 1, further comprising:

connecting, by the apparatus, with the another wireless device, using the channels selected by the apparatus, at least partly based on the channel map created by the apparatus.

20. The method of claim 19, further comprising:

generating, by the apparatus, a non-connectable discovery packet including the channel map created by the apparatus; and

communicating, by the apparatus, the non-connectable discovery packet while the apparatus is connected to the another wireless device.

6. An apparatus, comprising:

at least one processor;

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

receive wireless device discovery messages from one or more other wireless devices in wireless networks not connected to the apparatus, one or more of the received wireless discovery messages including channel information indicating status of one or more channels;

create a channel map that is at least partly based on the status of the one more channels indicated in the received one or more wireless device discovery messages; and

select channels for setting up wireless communication with another wireless device, the channels being selected at least partly based on the channel map created by the apparatus.

7. The apparatus of claim 6, further comprising:

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

receive second wireless device discovery messages from the one or more other wireless devices in the wireless networks not connected to the apparatus, one or more of the received wireless discovery messages including channel information indicating a change in status of one or more channels;

create a second channel map that is at least partly based on the change in status of the one more channels; and

tune channels for continued communication over an existing wireless connection with the another wireless device, the channels being tuned based on the second channel map created by the apparatus.

8. The apparatus of claim 6, wherein the channel information in the received wireless discovery message comprises at least one of a bit mask of used channels, a bit mask of used channels where a last several bits are used to indicate channel occupancy rate, and predefined used channel sets.

9. The apparatus of claim 6, wherein the wireless device discovery messages received by the apparatus are Bluetooth Low Energy advertising messages and the channel information included in the advertising messages is a channel map indicating wireless channels in use by the one of the one or more other wireless devices that sent the received advertising messages, the channel map further indicating one or more wireless channels having interference.

The apparatus of claim 6, wherein the creating, by the apparatus, of a channel map is performed by creating a new channel map of the apparatus using an LE Set Host Channel Classification Command, to specify a channel classification based on channels indicated in the received wireless device discovery messages.

11. A computer program product comprising computer executable program code recorded on a computer readable, non-transitory storage medium, the computer executable program code comprising:

code for receiving, by an apparatus, wireless device discovery messages from one or more other wireless devices in wireless networks not connected to the apparatus, one or more of the received wireless discovery messages including channel information indicating status of one or more channels;

code for creating, by the apparatus, a channel map that is at least partly based on the status of the one more channels indicated in the received one or more wireless device discovery messages; and
