According to an embodiment of the present invention, the frame body may further include position information of current beacon transmission apparatus, device identification information, and information on the number of currently paired devices. That is, the location information is provided to the receiving side so that the receiving side can determine whether to perform the pairing based on the distance from the beacon transmitting device. Also, based on the device identification information, a receiving side can determine whether to perform a connection with the device, and information indicating the number of currently paired devices is added to inform that the beacon transmitting device is currently paired with one or more devices, Under such circumstances, the receiving side can support the determination of pairing.

The beacon signal generation unit 310 may receive the currently paired network or device information from the device / network identification unit 320 and generate information on the number of currently paired devices. The beacon signal generation unit 310 also checks whether a device / network manager 324 of the device / network identification unit 320 confirms a predetermined number of Bluetooth beacon signal additionally sendable devices / Can be determined. For example, if the device / network manager 324 limits the number of paired devices or networks with five devices (this may be a default value and may be a later changeable value through the user interface) And / or if a connection to the network has already been established, the generation of additional Bluetooth beacon signals may be interrupted. This is to prevent a waste of wireless resources through network formation through the generation of an excessive Bluetooth beacon signal, and a value for minimizing such waste may be determined by a user or preset in the device as a default value.

In some cases, the beacon signal generation unit 310 may simultaneously generate a plurality of Bluetooth beacon signals to simultaneously establish pairing with various devices. At this time, each Bluetooth beacon signal can be broadcasted to different channels.

The device / network identification unit 320 is a component for identifying and managing the currently established network and / or device. This may include a list generating unit 322 and a device / network manager 324. [

The network ID information provides information for identifying the network to which the current pairing is made. The network identification information

The beacon transmission time information provides time information when the Bluetooth beacon signal is transmitted. Through this,

The beacon signal ID information is identification information for distinguishing each generated Bluetooth beacon signal. The beacon signal ID information can be later parsed to confirm characteristics of the network or communication settings with the connected devices.

The access device ID information may include identification information for a device that has received the Bluetooth beacon signal and is currently pairing established.

Through this information, the beacon transmission apparatus can clearly grasp the information associated with the currently paired network, and can utilize the information related to the network operation later.

 3, the device / network manager 324 manages the generation of the Bluetooth beacon signal based on the currently paired network / device list generated by the list generator 322 and the management of the currently paired network and / Can be performed. The device / network manager 324 can give an instruction to the beacon signal generator 310 in comparison with the number of currently paired networks and / or devices based on the maximum configurable network / device number limit information . That is, it can give information about whether to generate or stop further additional Bluetooth beacon signals. In addition, the device / network manager 324 determines a pairing related condition (e.g., a paired time condition (how long it is paired, etc.) for the network or the device based on the paired network identification information or the connected device identification information, , Frequency conditions (what frequency or channels are paired), or location information of the connected devices (how far they are connected to the device)). Based on this, it is possible to determine whether to transmit additional Bluetooth beacon signals according to a specific condition (which can also be set by default or changed by the user interface). For example, if two or more Bluetooth beacon signal transmissions are set to be disabled in a device within a radius of 5 m, the device / network manager 324 locates the base of the device information from the list and determines the position within 5 m of the currently paired device . If more than two, the Bluetooth beacon signal generation can be stopped. Thus, additional generation of the Bluetooth beacon signal can be managed in accordance with a specific condition. In some cases, the device / network manager 324 may classify other discovery devices that are not currently paired based on the currently paired device and / or network information, and transmit a beacon signal Generator 310 and / or the beacon signal transmitting unit 330. [0044] FIG.

The beacon signal transmitter 330 transmits the generated Bluetooth beacon signal to the receiver. The transmission scheme may include at least one of a broadcasting scheme, a unicasting scheme, and a multicasting scheme. The transmission method may also be performed under the control of the device / network identification unit 320. In other words, the Bluetooth beacon signal can be sent to multiple channels simultaneously by simultaneous transmission, and the Bluetooth beacon signal can be sequentially transmitted.
