Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a method of performing pairing between a coordinator and a device belonging to different networks according to an embodiment of the present invention.

Hereinafter, it is assumed that the network to which the coordinator or device belongs is a PBSS (Personal Basic Service Set) network. Here, the PBSS network is a network configured such that devices can directly communicate with each other without passing through the coordinator corresponding to the AP of the BSS (Basic Service Set) network. Here, the coordinator may be called a PCP (PBSS Control Point). Hereinafter, the coordinator will be referred to as PCP.

In the BSS network, since the APs and the devices are clearly distinguished, it is possible to distinguish which device is the AP and which device is the device in the network. However, in the PBSS network, since the devices are configured to operate also as the PCP, It is difficult to distinguish whether the device is a device or not.

In addition, the PBSS network is similar to a WPAN (Wireless Personal Area Network) system, but the PBSS network can be connected to the external network, unlike the WPAN system not connected to the external network. In addition, the PBSS network can support communication in the 60 GHz band.

In FIG. 1, a first PCP 110 belonging to a first network, a second PCP 120 belonging to a second network and a device A 130 are shown. And a plurality of devices may be included in the second network. Also, in the following drawings, the indications "first network" and "second network" respectively indicate that the device belongs to the first network and the second network.

In the first step, a button for instructing execution of pairing in the first PCP 110 is pressed by the user.

In the second step, the first PCP 110 broadcasts a beacon including first pairing information (PI1) indicating that the first PCP 110 is a device to perform the pairing.

In FIG. 1, a beacon including the first pairing information PI1 is shown to be broadcast only to the second PCP 120. However, this is for convenience of description, and all the devices belonging to the first network broadcast a beacon do.

In FIG. 1, the beacon broadcast by the first PCP 110 can only be received by the second PCP 120, and the device A 130 can not receive the beacon. For example, device A 130 may be located farther away from receiving the beacon broadcast by first PCP 110, and may not receive the beacon from first PCP 110.

In this case, the first pairing information PI1 includes first PBC (Push Button Configuration) information indicating that the button for instructing the first PCP 110 to perform the pairing is pushed, a MAC address of the first PCP 110, 1 identifier of the PCP 110, an identifier for the first network that is the network to which the first PCP 110 belongs, coordinator role information indicating that the first PCP 110 is the coordinator of the first network, and so on.

In another embodiment, instead of broadcasting the beacon including the first pairing information PI1, the first PCP 110 may transmit the beacon of the first PCP 110 and the device A 130 during the time intervals for data transmission between the first PCP 110 and the device A 130 It is also possible to broadcast the first pairing information PI1 in one or broadcast the first pairing information PI1 in the announcement time period as a time interval for informing information in the first network.

In the third step, the second PCP 120 broadcasts a beacon including the first pairing information PI1.

At this time, the second PCP 120 and the device A 130 belong to the same network and are located close to each other, so that the device A 130 transmits the first pairing information PI1 broadcasted by the second PCP 120 A beacon may be received.

In the fourth step, a button for instructing the device A 130 to perform the pairing is pressed by the user.

In the fifth step, the device A 130 receiving the first pairing information PI1 recognizes that the first PCP 110 is a partner device of the first PCP 110 itself.

Thus, device A 130 is coupled to the first network. The reason why the device A 120 is coupled to the first network is because the pairing between the first PCP 110 and the device A 130 is completed when the first PCP 110 and the device A 130 do not belong to the same network The data can not be transmitted to each other.

In a tenth step, the device A 130 transmits to the first PCP 110 the second pairing information PI2 indicating that the first pairing information PI1 and the self 130 are the partner devices to perform the pairing.

In the eleventh step, the first PCP 110 receiving the first pairing information PI1 and the second pairing information PI2 from the device A 130 determines that the device A 130 is a partner device of the self 110 I know.

If the first PCP 110 and the device A 130 recognize the other party as a device to be paired with the first PCP 110 and the device A 130 through the first through eleventh steps, The first PCP 110 and the device A 130 belonging to the same network are able to transmit data between the first PCP 110 and the device A 130. [

If the first PCP 110 and the device A 130 belong to the same network but the pairing between the first PCP 110 and the device A 130 is not completed or the pairing between the first PCP 110 and the device A 130 is completed, Data can not be transmitted between the first PCP 110 and the device A 130 when the first device 110 and the device A 130 do not belong to the same network.

Meanwhile, although a method of performing pairing between devices using the push button method has been described in the embodiment of FIG. 1, the embodiment of the present invention is not limited thereto. For example, the user may instruct each of the first PCP 110 and the device A 130 to perform pairing through a remote controller.
