Abstract

A complex communication apparatus transmits/receives voice information with other complex communication apparatuses through a set voice channel. The complex communication apparatus broadcasts a signaling packet expressing a destination identifier representing a desired communication type of one-to-one communication, group communication, and broadcast communication with other complex communication apparatuses and information of the set voice channel and performs voice communication with a complex communication apparatus corresponding to a destination identifier of other complex communication apparatuses, having received the signaling packet.

Claims

1. A method of communicating in a complex communication apparatus, the method comprising:

setting one voice channel of available voice channels for voice communication;

broadcasting a signaling packet expressing a destination identifier representing a type of voice communication and information of the one voice channel; and

performing voice communication with at least one complex communication apparatus corresponding to a destination identifier of a plurality of other complex communication apparatuses, having received the signaling packet.

2. The method of claim 1, wherein the broadcasting of a signaling packet comprises broadcasting the signaling packet through a physical channel of a wireless personal area network.

3. The method of claim 2, further comprising sensing peripheral information and transmitting the peripheral information to the outside through the physical channel.

4. The method of claim 1, wherein the type of the voice communication comprises at least one-to-one communication, group communication, and broadcast communication.

5. The method of claim 3, wherein the destination identifier is comprised in a destination identifier field of the signaling packet, and

a most significant bit of the destination identifier field represents one of the one-to-one communication, the group communication, and the broadcast communication.

6. The method of claim 5, wherein when all bits of the destination identifier field are 1, the identifier field represents the broadcast communication.

7. The method of claim 1, further comprising displaying that the one voice channel is being used in a voice channel table in which information of available voice channels is stored.

8. The method of claim 7, further comprising increasing a channel use count of the one voice channel by 1 in the voice channel table.

9. The method of claim 8, wherein the setting of one of available voice channels comprises selecting a voice channel that is not used and that has a small channel use count as the one voice channel with reference to the voice channel table.

10. A method of communicating in a complex communication apparatus, the method comprising:

receiving a signaling packet comprising a destination identifier field representing a destination identifier and a voice channel field representing voice channel information from other complex communication apparatuses;

setting, when the destination identifier corresponds with an identifier in which the complex communication apparatus has or when the destination identifier represents broadcast communication, a voice channel according to the voice channel information; and

performing voice communication with the other complex communication apparatuses through the voice channel.

11. The method of claim 10, wherein the receiving of a signaling packet comprises receiving the signaling packet through a physical channel of a wireless personal area network.

12. The method of claim 11, further comprising sensing peripheral information and transmitting the peripheral information to the outside through the physical channel.

13. The method of claim 10, wherein an identifier in which the complex communication apparatus has comprises an identifier of the complex communication complex communication apparatus and an identifier of a group comprising the complex communication apparatus, and

the destination identifier represents an identifier of the apparatus or an identifier of the group according to a most significant bit of the destination identifier field.

14. The method of claim 10, wherein the setting of a voice channel comprises determining, when all bit values of the destination identifier field are 1, that voice communication is the broadcast communication.

15. The method of claim 10, wherein the setting of a voice channel comprises

displaying that the set voice channel is being used in a voice channel table in which information of available voice channels is stored;

and

increasing a channel use count of the set voice channel by 1 in the voice channel table.

16. The method of claim 10, further comprising:

displaying, when the destination identifier does not correspond with an identifier in which the complex communication apparatus has and does not represent broadcast communication, that a voice channel corresponding to the voice channel information is being used in a voice channel table in which information of available voice channels is stored; and

increasing a channel use count of a voice channel corresponding to the voice channel information by 1 in the voice channel table.

17. A complex communication apparatus that performs voice communication, the complex communication apparatus comprising:

a wireless personal area network (WPAN) communication unit that transmits/receives a packet through a physical channel of a WPAN;

a bi-directional radio communication unit that transmits/receives voice information through a set voice channel; and

a controller that sets a voice channel to perform voice communication and that expresses a destination identifier representing a type of the voice communication and information of the set voice channel in a signaling packet and that broadcasts the signaling packet through the WPAN communication unit, when starting voice communication.

18. The complex communication apparatus of claim 17, further comprising a sensor unit that senses peripheral information or that receives sensing information from another sensor and that transmits the sensing information to the outside through the physical channel.

19. The complex communication apparatus of claim 17, wherein the controller sets a voice channel corresponding to the voice channel information according to a destination identifier of the signaling packet, when receiving a signaling packet from other complex communication apparatuses through the WPAN communication unit.

20. The complex communication apparatus of claim 17, wherein the destination identifier represents one of an identifier of the complex communication apparatus, a group identifier, and broadcast communication.
