Description

Method for game between wireless terminal's by using bluetooth chip}

The present invention relates to a game method between wireless terminals, in particular using a Bluetooth chip that is suitable for playing games between mobile terminals such as laptop computers, mobile phones, PDA (Personal Digital Assistant, portable information terminal) equipped with a Bluetooth chip. It relates to a game method between wireless terminals.

Conventional games using wireless terminals such as mobile phones and PDAs are first connected to a mobile communication company providing an Internet service, and then played through a server of a site providing a game.

Thus, the game method using a wireless terminal is composed of a different method for each wireless communication service provider, but the following two methods are representatively used in the detailed technology.

<Prior Art 1>

1 is a block diagram of a system for a game using a conventional wireless terminal, Figure 2 is a view showing a game menu window of the wireless terminal in FIG.

Here, reference numeral 11 is a wireless terminal, 12 is a wireless network, 13 is a gateway of a communication company, 14 is a game server, 15 is a game progress server, 16 is a web server, and 17 is a communication company internal server.

Thus, when a user wants to play a game using a wireless terminal, the user plays a game using an existing wireless communication network.

In other words, if a user wants to play a game, he or she must have a mobile phone with wireless internet as a prerequisite.

In addition, a user having a wireless terminal 11 capable of internet accesses a communication company through an existing wireless network. In this case, the terminal undergoes user authentication through communication with the internal server 17 of the telecommunication company, and the telecommunication company server transmits various menus as shown in FIG. 2 to the wireless terminal 11.

When the user selects a game from the menu thus transmitted, the game server 14 is connected.

The signal transmitted from the wireless terminal 11 passes through the carrier gateway 13, and HTML (HyperText Markup Language) and HDML (Hierarchical Data Manipulation Language) which can be recognized by the actual game progress server 15 and the web server 16. Or WML (Wireless Markup Language).

And you can play games on the Internet.

However, when playing the game in this way, the user had to bear a separate communication fee.

<Prior Art 2>

3 is a block diagram of a system for a game using a conventional wireless terminal. Playing the game in the system as shown in FIG. 3 shows a case where the game is embedded in the mobile terminal.

In this case, if a user wants to play a game, he or she must purchase a wireless terminal in which the game is built or upgrade the terminal capable of supporting the game at a service center.

Thus, the user who wants to play the game selects the game from the wireless terminal 11 own menu. And to play the game, you need to buy virtual currency, which is done online, and you have to pay a certain amount.

If you have a virtual currency purchased like this, you can play a game that is already built. And because it is not a game using communication, a separate communication fee is not charged while the game is in progress.

After the game is over, you can send the score, in which case you will be charged a separate fee per case using one-way communication.

In FIG. 3, the telecommunication company gateway 13 and the telecommunication company internal server 17, which are parts after the wireless network 12, are used only in two cases of purchasing virtual currency and transmitting scores.

However, in the case of the prior art 1, a user who wants to play a game can access the game only when the user subscribes to an Internet service provided by each communication company, and cannot access the game when the user does not subscribe to the Internet service. Therefore, since the communication fee is charged from the moment of access to the game, there is a charge for performing the game.

The progress of the game is connected to the game server from the start of the game until the end of all the game and exit the game menu, and after leaving the menu is connected to the carrier server. The part using the wireless network is a poor environment that is relatively low in stability and slow compared to the wired network.

Therefore, there is a limited transmission bandwidth, there is a problem that there is always a relatively long delay and the possibility of connection interruption.

In addition, there is a problem such as a delay in time due to encoding / decoding at the carrier gateway. When several people enjoy a game together, there is a problem in that the game progress of all gamers is affected if one terminal of the multiple terminals is in poor connection.

On the other hand, in the case of the prior art 2, unlike the prior art 1, there is no separate communication fee during the game. This is because the airwaves are not used, which can solve the problems of the prior art 1.

However, only one user is playing a game against a built-in program, and there is a disadvantage that several people cannot play together.

In addition, it is necessary to have a terminal with a built-in game, and in the case of the built-in game, only a limited game is supported due to a problem of memory capacity.

In addition, in order to enjoy the game, you need to purchase virtual money, which means additional costs will be incurred. In addition, in order to transmit the results of the game, there is a drawback in that the user must pay the cost per case separately from the call charge by accessing the server of the carrier.

Furthermore, in case of the related art 2, the wireless terminal is used as a game machine, and the limited memory can only limit the types of games, and satisfies the needs of users who are currently playing games competing with each other in one game space on the Internet. There is a limit that cannot be made.

As such, the conventional game method has a relatively long delay time compared to the wired network because of the existing wireless communication network, and there is a disadvantage in that connection interruption occurs due to errors and other problems. In addition, there is a problem that adds to the customer burden because of the additional subscription cost.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is to provide a game between wireless terminals so as to play games between mobile terminals such as laptop computers, cellular phones, PDAs, etc. equipped with a Bluetooth chip. The present invention provides a game method between wireless terminals using a Bluetooth chip that can solve the problems caused by using a wireless communication network through a direct connection, and incorporate game progress and access functions to reflect game results.

The operation of the game method between wireless terminals using the Bluetooth chip according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, Bluetooth is a technology specification that wirelessly connects portable PCs, mobile phones and other mobile devices at low cost within a narrow range. It uses radio frequency to exchange voice and data without physical cable for communication between various digital devices.

For example, when Bluetooth technology is implemented in mobile phones and laptops, you no longer need to use the cumbersome cables you currently use to connect mobile phones and laptops. Virtually all digital devices, including printers, desktops, fax machines, keyboards and joysticks, can be part of a Bluetooth system.

Bluetooth was launched as an open standard by five companies, Ericsson, Nokia, Intel, Toshiba and IBM, in 1998, forming a consortium called the Bluetooth Special Interest Group (SIG). Since then, Lucent Technologies, Motorola, Microsoft, and 3Com have joined the SIG (Special Interest Group), with 1790 members worldwide (2000.4.20). As the number continues to grow, Bluetooth is now becoming a global standard for short-range wireless communications.

The specification and characteristics of Bluetooth are as follows.

First, the Bluetooth Radio module provides up to 1Mbps data rate using 2.4GHz Industrial Scientific Medical (ISM). In order to reduce the effects of fading interference, the frequency hop transceiver technique is applied, and the modulation scheme uses a binary FM scheme.

The main features of the Bluetooth protocol are:

i) Baseband module carries baseband protocol, provides routing function with low-level link of remote device, and ii) Link Manager Protocol provides link control function such as link setup. iii) Logical link control and adaptation protocol (L2CAP) modules provide upper layer protocol multiplexing, packet fragment reassembly, and quality of service (QoS). Iv) RFCOMM is an upper layer of L2CAP and provides a function of transmitting data transmitted from the application layer.

Bluetooth is a protocol that provides short-range wireless links between electronic devices in homes and offices (10m radius), proposed by Ericsson, Toshiba, Nokia, IBM, and Intel. Ad hoc network between mobile, stationary and mobile devices provides functions such as File Transfer, Dial up networking, Synchronization, 3 in 1 Phone, Ultimate Handset, Computer Speak phone, Cordless Computer and Conference Table.

Therefore, Bluetooth is settled in devices such as printers, PDAs, desktop PCs, fax machines, keyboards and joysticks to provide voice and non-voice services wirelessly.

The wireless access technology provided by Bluetooth is based on Ad hoc network and provides data service using TCP / IP and interface functions such as Host Interface Device (HID), Object Exchange Protocol (OBEX) and audio in Piconet environment. to provide. In order to provide a stable link in a noisy environment, Bluetooth Radio provides a fast sensing and frequency hopping method for the environment.

In addition, compared to other systems using the same frequency band, it has the advantage of quickly hopping to a new frequency and using small packets, thereby excluding interference by other signals as much as possible. In particular, the Bluetooth Radio can reduce the effects of random noise generated in a long-distance link environment through FEC (Forward Error Correction) for error recovery.

Bluetooth transmission provides a full-duplex method in which a circuit and packet switching mode are mixed based on a time division duplex (TDD). Packets used in Bluetooth generally use one TDD slot, but can be extended to five slots. The following shows the characteristics of the TDD slot.

-Provide synchronous and asynchronous channel

One asynchronous data channel and up to three synchronous voice channels

-64 kb / s synchronous voice channel

The asynchronous channel provides up to 57.6 kb / s in the carrier direction, allows up to 432.6 kb / s in the symmetric link, and supports up to 721 kb / s in any direction. The configuration module of the Bluetooth system is as follows.

-radio unit (see Radio section)

link control unit (see Baseband section)

link management (see Link Management section)

-software functions (see Software Framework, pc, Telephone section)

And a wireless terminal game system using a Bluetooth chip is composed of a Bluetooth chip emulator, a game version management server.

Here, the Bluetooth chip emulator allows other wireless devices with Bluetooth chips to maintain the same interface. Therefore, it performs a program function that allows the game to be run independently from the wireless terminal so that games can be enjoyed between different models. For example, if you play a game using IMT-2000 terminal and laptop equipped with Bluetooth chip, there may be a problem in game progress due to different interface. Bluetooth chip emulator is a program that solves this problem. Even if you use (hardware), the system does not interfere with the game.

In addition, the game version management server is to allow the download of the latest version and set up if the game version between each game terminal is different. In other words, if each terminal has a different version in the game to connect to the game version management server to upgrade the latest version of the game to support the game to enjoy improved games.

Therefore, the wireless terminal 31 should have a built-in Bluetooth chip, and also store the game program on the memory.

The wireless terminal 31 of the user who wants to play a game under these conditions selects a game function of the terminal menu and selects a game type. After that, a virtual game room is opened and waiting for the connection so that other terminals who want to play the game can connect. When the game population is all gathered, the game can be started, and when the game ends, the result is displayed on each wireless terminal 31.

Meanwhile, in FIG. 6, each of the wireless terminals 31a, 31b, and 31c uses the piconet 33 to enjoy a game at the same time through wireless.

Here, the piconet 33 is any network which performs wireless communication by Bluetooth 32a. 32b. 32c mounted in each of the wireless terminals 31a, 31b, and 31c.

The piconet 33 may be formed of up to eight Bluetooth-equipped wireless terminals, one of eight being a master and the other being a slave.

Therefore, in order to enjoy the game, the same game should be stored in all the wireless terminals 31. If the same game is not stored in any one of the wireless terminals 31, the mobile communication server 36 is connected through the public network 34, and the game server 38 is downloaded through the general network 37. Find the game.

Referring to the operation of the present invention in more detail as follows.

7 is a flowchart of a game method between wireless terminals using a Bluetooth chip according to the present invention.

Thus, when the user selects the menu button of the wireless terminal 31, the user selects a mode type to select a game selection or a game download mode.

When the user selects a game selection mode in the mode type selection, the user can select a game mode. There are two game modes, local and piconet.

The local game is a mode in which the user enjoys the game alone with only his wireless terminal 31. Piconet games are games played in a range of piconet networks with Bluetooth chips, and can accommodate up to eight people.

After the user selects the game mode, the user is queried again before actually entering the game to ask whether the game should continue.

Thus, if the user selects using the function key of the wireless terminal 31 not to proceed with the game, it returns to the mode type selection screen again.

In addition, when the user selects to continue the game by using the function key of the wireless terminal 31, the local game or piconet game is executed.

8 is a flowchart illustrating a case where the user selects a local game. In addition, a flowchart when the user selects a piconet game is shown in FIG. 9.

In addition, when the game is not in the wireless terminal 31, if a mode for downloading the game is selected, it is queried again whether to download the game. Thus, when the user selects that the user will not perform the game download by using the function key of the wireless terminal 31, the screen moves to the mode type selection screen. When the user selects to perform the game download by using the function key of the wireless terminal 31, the user accesses the game server 38 through the public network 34. In this case, a flowchart for downloading a game is illustrated in FIG. 10.

FIG. 8 is a detailed flowchart illustrating a local game execution step in FIG. 7.

Thus, when the local game is started, the user proceeds to play the game by using the wireless terminal 31 of the user. Thus, after the user executes the game, the result is stored in the memory in the wireless terminal 31, and the result is displayed on the screen of the wireless terminal 31. The game then ends.

9 is a flowchart illustrating a piconet game execution step in detail in FIG. 7.

Thus, when the piconet game starts, it is determined whether the user's wireless terminal 31 is the first game of the piconet game.

If the user's wireless terminal 31 is the first game of the piconet, the game is started by participating in the piconet game as a master having administrative authority in the game. If it is not the first game of the piconet, it is determined whether the game version is identical to that of the wireless terminal 31 of another user who is a master who has previously formed the piconet game.

If the game version and the game version of the other user wireless terminal 31, which is the master, are the same, the game starts by joining the piconet game as a slave.

In a piconet that can be enjoyed by eight people, only one person becomes the master and the other seven become slaves.

Next, the game is played in the piconet, and the result is stored and outputted on the screen of each wireless terminal 31. Next we end the game.

In addition, if the game version and the game version of the wireless terminal 31 of another user who is the master is not the same, it is possible to download the same game as the game version of the master.

FIG. 10 is a detailed flowchart illustrating a game download execution step in FIG. 7.

Thus, when game download starts, the mobile communication server 36 is connected. The mobile communication server 36 then checks the subscriber authentication of the user's wireless terminal 31.

Here, for example, subscriber authentication may be performed to check whether a wireless terminal is subscribed to each telecommunication company.

If this authentication fails, the connection is terminated.

If the authentication is confirmed, the mobile communication server 36 is connected to the game server 38.

You select a download game, then select a version and download it.

After the download is performed, check if the download is successful. Therefore, if the download is successful, a success message is output to the screen of the wireless terminal 31, and if the download is not successful, an error message is output to the screen of the wireless terminal 31.

In addition, after starting the game, other users are allowed to participate or not participate depending on the type of game. Thus, depending on the type of game, the master may allow other users to join, or block it from participating.

After the game is finished, the master transmits the game result value to the wireless terminal 31 of the game participant to be outputted respectively. Then, each user can check the game result through the screen output based on the result value received from his wireless terminal 31.

On the other hand, if an accident occurs, proceed as follows.

First, when a call is received while playing a game with the wireless terminal 31, it is possible to determine whether or not to receive an incoming call. Thus, a program that performs one monitoring role on the wireless terminal 31 is operated, and the game is deactivated to receive a call and then placed in a call state.

In addition, if the participant abruptly withdraws during the game, the game program is set to delete the withdrawal or stop the operation according to the nature of the game.

As such, the present invention is to play a game between the mobile terminal, such as a laptop computer, a mobile phone, a PDA equipped with a Bluetooth chip.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the game method between wireless terminals using the Bluetooth chip according to the present invention performs a direct connection between the wireless terminals to play games between mobile terminals, such as notebook computers, mobile phones, PDAs equipped with a Bluetooth chip. By doing so, there is no need to use a wireless communication network, so there is no need to bear a separate communication cost.

In addition, the present invention has the effect that can proceed to the game where several people compete at the same time.
