The smartphone 200 body is equipped with a power supply unit 290 for supplying power to the smartphone 200. The power supply unit 290 may be built in the body of the smart phone 200 or may be detachable from the outside of the terminal body.

Hereinafter, a method for controlling the alcian toy 100 using the above-described alcian toy 100 and the smartphone 200 will be described.

Figures 4A and 4B show an embodiment of controlling the Alcian toy in close proximity with respect to the Alcian toy control system via the network of the present invention.

4A and 4B show a case in which the smartphone 200 is located in a short distance from the alcian toy 100 and the smartphone 200 is in a range in which the smartphone 200 can communicate directly with the alcian toy 100. FIG. Module 120 is operated in the access point mode, and FIG. 4B shows the case in which the communication module 120 for the toy child is operated in the client mode.

When the smartphone 200 and the alcyon toy 100 are located in close proximity, the alcian toy communication module 120 is basically operated in the access point mode as shown in Fig. 4A. For example, if an AP is connected to the Internet by connecting the Internet line to the AP based on the AP in the home, for example, the AP is connected to the Internet. If the AP is used without connecting to the Internet line, , The function of sharing the Internet will not work. In the same principle, the atomic toy of the present invention exists in a state in which it can communicate with clients connecting without being connected to the Internet when operating as an AP.

4A, the communication between the alcyon toy 100 and the smartphone 200 is performed through the wireless channel 330 formed between the communication module 120 for the tobacco and the communication module 220 for the terminal. That is, the first signal is transmitted from the LCD game machine 100 to the smartphone 200 through the wireless channel 330, and the control signal is transmitted from the smartphone 200 to the LCD game machine 100.

The toys communication module 120 (or the terminal communication module 220) may use a separate preamble for measuring the quality of the radio channel during the communication process, and may communicate with the communication module 120 for the to- The quality of the wireless channel 330 between the terminal communication module 220 and the wireless channel 332 between the communication terminal 120 and the router 300 is measured.

The quality of the wireless channel 330 formed between the communication module 120 for the toys and the communication module 220 for the terminals is lower than the quality of the wireless channel 330 formed between the communication module 120 for the toys and the router 300 , The communication module 120 for the toy toys is switched to the client mode and operated. That is, since it is determined that the quality of the wireless channel 332 formed between the communication module 120 for toy and the router 300 is better, the wireless channel 332 is used instead.

The first signal is transmitted through the wireless channel 332 formed between the communication module 120 for the toe toy and the router 300, And the control signal is transmitted to the wireless channel 334 formed between the communication module 220 for the terminal and the router 300. [

In the case where the smartphone 200 and the alcyon toy 100 are close to each other, the communication module 120 for the toys toy operates basically in the access point mode, but switches to the client mode according to the quality of the wireless channel Therefore, the yield of communication can be greatly improved.

Also, the communication module 120 for the toy toys can operate in a diversity mode in which the access point mode and the client mode are alternately repeated, and in the diversity mode, it is possible to improve the communication through the diversity gain Do.

Specifically, when it is determined that the quality of the wireless channel 330 formed between the communication interface module 120 for the toys and the communication module for the terminal 220 is lowered to a predetermined value or less, the communication module 120 for the to- Diversity mode, and the access point mode and the client mode can be repeated in a time division manner.

When the alcian toy communication module 120 operates in the diversity mode, the alcian toy communication module 120 can receive a control signal twice from the terminal communication module 220 and the router 300, respectively. That is, when the communication module 120 for the toy toys is in the access point mode, the control signal is received from the terminal communication module 220, and when the communication module 120 for the toy toys is in the client mode, A control signal is transmitted. The toy communication module 120 can process the received signal twice through an optimized diversity technique such as an alamouti code.

Similarly, in the diversity mode, the terminal communication module 220 can receive the first signal twice from the communication module 120 for the tobacco game and the router 300, respectively, and can use the diversity technique such as the Alamouti code And can process the received signal. Thus, the communication efficiency can be greatly improved and the image information included in the first signal can be transmitted more efficiently.

Meanwhile, FIG. 5 shows an embodiment in which the alcium toy is controlled at a remote place in connection with the Alcian toy control system through the network of the present invention. 5 shows an embodiment in which the smart toy 200 is used to control the alcian toy 100. However, it is also possible to use a device such as a PC, a notebook, and a tablet in addition to the smart phone 200, It is also quite possible to control the toy 100.

When the smartphone 200 and the alcian toy 100 are located at a remote location and the smartphone 200 is out of the range capable of directly communicating with the alcian toy 100, the alcian toy communication module 120 operates in the client mode do. The toy communication module 120 may be directly connected to the Internet network 310 through the router 300 and the terminal communication module 220 may be connected to the Internet network 310 through the other router 302.

5, when the smartphone 200 and the alcian toy 100 are located at a remote location, the communication between the alcyon toy communication module 120 and the router 300 is performed through a wireless channel 332 1 signal is transmitted and a control signal is transmitted through a wireless channel 336 formed between the terminal communication module 220 and the other router 302.

At this time, the peer-to-peer communication between the communication terminal module 120 and the terminal communication module 220 may be blocked by the firewall / NAT. In order to solve this problem, the computer game control system 1000 through the network of the present invention introduces a rendezvous server 320 to support UDP hole punching.

Specifically, the rendezvous server 320 is configured to be connected to the Internet network 310 in order to allow a connection between the communication module 120 for the toy and the communication module 220 for the terminal, which are blocked by the firewall / NAT. The rendezvous server 320 receives a packet including IP and port of the communication terminal 120 for the tobacco toy from the communication terminal 120 for the toy toys and transmits the packets including the terminal communication module 220, A packet including an IP (IP) and a port (PORT) of the communication module 220.

The process of proceeding through the hole punching proceeds in the following four stages.

When the object A wants to connect to the object B, the object A sends a request to the rendezvous server to configure the object B and the UDP session. 2) The rendezvous server answers the message containing the public and private end points of the object B 3) At the same time, the Rendezvous Server sends a message containing the public and private endpoints of object A to object B using the UDP session associated with object B. 4) Object A sends a UDP packet of object B to both endpoints, Similarly, object B starts sending UDP packets to each endpoint of object A, and is fixed and connected to the first ending node.

Through the above process, UDP hole punching is performed to enable communication between the communication module 120 for the toy child and the communication module 220 for the terminal, and a method using a conventional relay server, a method using a static IP, a port forwarding Or port rewarding, and it is possible to perform data communication with less delay due to direct connection between peers.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission via the Internet) . The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers of the technical field to which the present invention belongs.
