Description

MOBILE TERMINAL DEVICE FOR TRANSMITTING ENORMOUS VOLUME SERVICE DATA TO PERIPHERAL EQUIPMENT AND METHOD THEREOF}

The present invention relates to a mobile terminal device and a data transmission method using the same, and a mobile terminal device and a method for transmitting a large amount of service data to the peripheral device.

The present invention is derived from a study conducted as part of the IT growth engine technology development project of the Ministry of Knowledge Economy.

Recently released portable terminal devices have a function of capturing and playing a video in real time despite its small size. In particular, recently released portable terminal devices can play and shoot HD-quality video in real time. Mobile terminals, such as a personal digital assistant (PDA), a smart phone, a portable multimedia player, and a mobile communication terminal, are representative examples.

Recently, portable terminals have been released in size in consideration of convenience of movement. Therefore, the size of the output device such as a speaker and an LCD screen, which is basically installed in the portable terminal, also becomes smaller. This means that a portable terminal having a shooting function can shoot a video in HD size, but because the LCD screen is small for mobility, there is a limit in playing in HD size. For this reason, HD-quality videos recorded by users are transferred to a peripheral device with high output performance such as a large LCD screen and a large speaker for playback. That is, the users play the moving image by moving the moving image stored in the portable terminal to a peripheral device providing a comfortable environment, such as a home theater, a car audio, a television, or the like. To this end, users transmit a video stored in a portable terminal to the peripheral device through a wired or wireless network, or transmit an auxiliary storage device to the peripheral device through a medium, and the peripheral device plays the received video.

However, as described above, the process of moving service data such as moving pictures is very cumbersome, and more inconvenient for a user who has poor operation ability of the terminal. That is, there is an inconvenience that the user has to connect the portable terminal and the peripheral device by wire, and the wireless network needs to be set up for the wireless connection, so that the user requires high device operation capability. Also, after the playback is completed in the received peripheral device, it should be deleted manually.

In conclusion, in the conventional method of moving data stored in a portable terminal to a peripheral device having excellent output performance, there are three main problems as follows. First, sufficient knowledge of the user's method of moving the data (or content) mentioned above, and sufficient maneuverability of a medium used for moving the data, such as a memory card and a wired connection device, are required. Second, sufficient knowledge of various network devices between portable terminals and peripheral devices is also required. Third, after playback is completed in the received peripheral device, the user must directly manipulate the peripheral device to delete the received data. That is, in some cases, execution of data in a comfortable environment is a main purpose of the user, and storing the data in the peripheral device may not be the main purpose. In this case, since the data transmitted to the peripheral device remains in the conventional method, it is cumbersome for the user to manually erase the data remaining in the peripheral device through the peripheral device operation.

Accordingly, an object of the present invention is to provide a mobile terminal device for transmitting service data to a peripheral device that provides a comfortable environment.

Another object of the present invention is to provide a method for transmitting service data stored in a mobile terminal device to a peripheral device that provides a more comfortable environment.

In order to achieve the above object, in the method for transmitting a large amount of service data stored in the mobile terminal device according to an aspect of the present invention to the peripheral device, the mobile terminal device searching for the peripheral device using a short-range wireless communication method, Configuring, by the mobile terminal device, a broadband network connection with the searched peripheral device through a broadband wireless communication method, and transmitting, by the mobile terminal device, a large amount of service data to the searched peripheral device through the configured broadband network connection. Include.

According to another aspect of the present invention, a mobile terminal apparatus for transmitting a large amount of service data to a peripheral apparatus includes a first transmission module and a broadband wireless communication network communicating with the peripheral apparatus through a local area network. A transmission unit including a second transmission module communicating with the peripheral device through a network; a peripheral device search unit configured to search for the peripheral device by establishing a local area network connection through the first transmission module; and through the second transmission module. And a network connection unit constituting a broadband network connection with the retrieved peripheral device, and a service connection server unit transmitting the service data to the peripheral device through the configured broadband network connection.

According to the present invention, a user does not need to directly transfer service data stored in a mobile terminal device to a peripheral device for realizing a service. In addition, since the mobile terminal device is connected to a peripheral device that reproduces service data through a short-range wireless network connection, the mobile terminal device does not need to know the network address of the mobile terminal device and the user is stored in the mobile terminal device without sufficient knowledge of how to move the data. Service data can be easily moved to peripheral devices. In addition, after playback is completed in the received peripheral device, the user does not need to directly delete the transmitted data by manipulating the peripheral device, thereby maximizing user convenience.

The present invention transmits a large amount of service data stored in a mobile terminal device to a comfortable environment, that is, a peripheral device having excellent output performance. The present invention uses the traditional client-server model in terms of playing back service data. However, the present invention is a way in which the client and server are the opposite of the existing role. That is, the mobile terminal device of the present invention holds a server and transmits the service data, and the peripheral device having a relatively higher output performance than the mobile terminal device serves as a client receiving the service data.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the preferred embodiment of the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

For example, a mobile terminal device according to an embodiment of the present invention may include a personal digital assistant (PDA), a smart phone, a portable multimedia player (PMP), a mobile communication terminal, and the like. The peripheral device according to the embodiment of the present invention may include a home theater, a car audio, a television, a desktop, a notebook, and the like, which reproduce a large amount of service data such as multimedia. .

In addition, in describing an embodiment of the present disclosure, the mobile terminal device may include a Bluetooth module for performing Bluetooth communication. However, according to the choice of the manufacturer and user of the mobile terminal device, in addition to the Bluetooth communication method, a short-range wireless communication method such as Infrared Data Association (IrDA), Wireless Lan (WLAN) and Shared Wireless Access Protocol (SWAP) can be used. Modules that can be used may be provided. Through the short range wireless communication module, the mobile terminal device according to an embodiment of the present invention can configure a short range network connection.

In addition, in describing an embodiment of the present disclosure, the mobile terminal device may further include a Wi-Fi module for performing Wi-Fi communication while performing Bluetooth communication. However, a module capable of using a broadband wireless communication method such as a High Speed Downlink Packet Access (HSDPA) method and a Wibro method may be provided according to a selection of a manufacturer and a user of a mobile terminal device. Through such a broadband wireless communication module, the mobile terminal device according to an embodiment of the present invention can configure a broadband network connection.

As described above, the mobile terminal device according to the embodiment of the present invention includes both a short range wireless communication module and a wide area wireless communication module, thereby configuring both a local area network connection and a wide area network connection.

Since the above-described short-range wireless communication method of the infrared wireless communication, wireless LAN and swap, and the above-mentioned broadband wireless communication method of the Wi-Fi communication, HSDPA and WiBro communication is already known technology, a detailed description thereof will be omitted. .

1 is a block diagram of an entire system according to an embodiment of the present invention.

Referring to FIG. 1, the entire system according to an embodiment of the present invention includes a mobile terminal device 100 and a peripheral device 200.

The mobile terminal device 100 searches for the peripheral device 200 using a short range wireless communication method such as a Bluetooth communication method, an infrared wireless communication method, a wireless LAN, and a swap, and forms a short-range network connection with the found peripheral device. The mobile terminal device 100 performs the device connection 10 with the peripheral device 200 through the configured local area network connection.

When the device connection 10 is completed, the peripheral device 200 and the mobile terminal 100 configure a broadband network connection by a broadband wireless communication method such as a Wi-Fi communication method, an HSDPA communication method, and a WiBro communication method. Through the configured broadband network connection, the mobile terminal device 100 performs streaming data transmission 10 of service data (or content) such as a video to the peripheral device 200.

As described above, in the entire system according to an exemplary embodiment of the present disclosure, the mobile terminal device 100 searches for and recognizes any one of the peripheral devices 200, 200, 300, and 400 through a local area network connection. When the device connection process and the device connection step are completed, a data transmission process of transmitting service data to the peripheral device 200 recognized by the mobile terminal device through a broadband network connection is performed.

FIG. 2 is a block diagram illustrating each internal configuration of the mobile terminal device and the peripheral device shown in FIG. 1.

Referring to FIG. 2, in order to perform a device connection process and a data transmission process, the mobile terminal device 100 may include a transmitter 110, a peripheral device searcher 120, a transmitter-side network connection unit 130, and a service connection server unit. 140, the peripheral apparatus 200 includes a receiver 210, a receiver-side network connector 220, and a service data execution unit 240.

The transmitter 110 of the mobile terminal device 100 includes a first transmission module 112 and a second transmission module 114. The first transmission module 112 communicates with the peripheral apparatus 200 using a short range wireless communication scheme. The second transmission module 114 communicates with the peripheral apparatus 200 using a broadband wireless communication scheme. The receiver 210 of the peripheral device includes a first receiving module 212 and a second receiving module 214. The first receiving module 212 communicates with the first transmitting module 112 in a near field communication manner, and the second receiving module 214 communicates with the second transmitting module 114 in a broadband wireless communication manner. Receive service data.

The mobile terminal device 100 includes a peripheral device search unit 100 for configuring a device connection with any one of a plurality of peripheral devices. The peripheral device search unit 110 generates its own identification information such as address information as a discovery message according to the discovery protocol. When the discovery message is generated, the peripheral device search unit 110 drives the first transmission module 112. The driven first transmission / reception module 112 transmits the generated discovery message to the first reception module 212 of the peripheral device 200. The peripheral device 200 generates a response message to the discovery message received through the first receiving module 212. The generated response message is transmitted to the first transmitting module 112 through the first receiving module 212. When the first transmission module 112 receives the response message, the device connection 10 between the mobile terminal device 100 and the peripheral device 200 is configured. That is, the mobile terminal device 100 and the peripheral device 200 are paired to recognize the mobile terminal device 100 and the peripheral device 200.

When the configuration of the device connection 10 is completed, the transmitting network connection unit 130 creates a broadband network connection most suitable for the target service in order to configure the broadband network connection.

When the broadband network connection is created, the service connection server unit 140 of the mobile terminal device 100 is driven, and the receiving network connection unit 220 of the peripheral device 200 is a broadband generated by the transmitting network connection unit 130. Create a broadband network connection corresponding to the network connection.

Subsequently, when the configuration of the broadband network connection is completed by the network connection units 130 and 220 of the transmitting / receiving side, the peripheral apparatus 200 drives the second receiving module 212 and the mobile terminal apparatus through the broadband network connection. (100). At the same time, the mobile terminal device 100 permits the connection of the peripheral device 200 and transmits service data to the peripheral device 200 in real time through the second transmission module 114.

The service data execution unit 240 of the peripheral device 200 receives the service data transmitted by the streaming method and reproduces the data in real time.

The above-described short-range network connection is generated through a short-range ad-hoc network in consideration of the specificity of the mobile terminal device, and a higher bandwidth broadband network connection (infrastructure mode) through the generated ad-hoc network connection. Is generated.

As such, in the embodiment of the present invention, there are two steps.

In the first step, when the peripheral device 200 is found through the peripheral device searching unit 120 of the mobile terminal device 100, the mobile terminal device 100 and the peripheral device 200 recognize each other, and then the network connection unit. (130, 230) re-create the broadband network connection most appropriate for the target service.

In the second step, when the appropriate broadband network connection is created, the service connection server unit 140 of the mobile terminal device 100 is driven, and the peripheral apparatus 200 establishes the broadband network connection by the receiving network connection unit 220. When the configuration is completed, the second receiving module 212 is driven to access the mobile terminal device 100. At the same time, the mobile terminal device 100 allows the peripheral device 200 to connect and transmits the service data through the second transmission module 114. Thereafter, the peripheral device 200 drives the service data execution unit 240 to execute the service data received through the second receiving module 212.

As a result, when the device connection 10 is completed between the two devices 100 and 200, the mobile terminal device 100 functions as a kind of server, and the peripheral device 200 functions as a client. When the peripheral device 200 serving as a client requests a service transmission to the mobile terminal device 100 functioning as a server, the mobile terminal device 100 streams service data in response to a request of the peripheral device 200. The device 200 reproduces the streamed service data in real time.

The reason why the device connection 10 process is required between the mobile terminal device 100 and the peripheral device 200 is because of the uniqueness of the mobile terminal device. In other words, in the conventional client / server structure, the process of connecting a client to the server, the client knows the server's address (URL or IP) in advance, uses it to connect to the server, and is provided with a service.

However, since the mobile terminal device 100 such as a PDA, a smart phone, a PMP, and a mobile communication terminal does not have a network address unless an IP connection is established, the peripheral device 200 cannot access the mobile terminal device 100.

In addition, even when the peripheral apparatus 100 recognizes the network address of the mobile terminal apparatus 100, the IP by the DHCP (Dynamic Host Configuration Protocol) is continuously changed due to the mobility of the mobile terminal apparatus 100. 200 and the mobile terminal device 100 may not be connected. That is, the mobile terminal device 100 changes its network address every time it is connected to the network, so that the method for notifying the peripheral device 200 is not easy. In order to solve this problem, in the embodiment of the present invention, the mobile terminal device 100 configures the device connection 10 through a local area network connection by the near field communication method, and its address information by the near field communication method. Notify the peripheral device 200. The mobile terminal device 100 supports a short distance ad-hoc network such as Bluetooth communication, infrared wireless communication, and the like. The mobile terminal device 100 based on the short-range ad-hoc network has a short wireless connection distance and a small bandwidth, but has an advantage of allowing a user to connect with a peripheral device without special knowledge or preparation for the network. In addition, since the object to be connected is within a short distance and can be visually confirmed, even if a beginner with poor operation ability attempts, there is a small possibility of being connected incorrectly.

FIG. 3 is a diagram illustrating a device connection process illustrated in FIG. 1.

Referring to FIG. 3, a user presses a device search button (not shown) using a short range wireless communication network in the mobile terminal device 100 and reviews a list of connectable peripheral devices 200, 300, and 400. After the user checks the peripheral devices 200, 300, and 400, the user selects the peripheral device 200 most suitable for the purpose. The two devices then use a local area network to complete the device connection. That is, using the short range wireless communication method, the mobile terminal device 100 can easily inform its neighbors 200, 300, and 400 of its existence. Accordingly, the peripheral apparatuses 200, 300, and 400 may recognize the existence of the mobile terminal apparatus 100, and may recognize the mobile terminal apparatus 100 as a server and access the same.

However, the short-range network connection implemented by the short-range wireless communication method is very low. Therefore, local area network connection is undesirable as a communication method for transmitting a large amount of service data. Therefore, the mobile communication terminal device resets from the local area network connection to the broadband network connection.

The peripheral device that recognizes and accesses the mobile terminal device 100 as a server through a local area network connection identifies a new connectable broadband network connection suitable for a service bandwidth and newly creates a network connection. As mentioned above, broadband network connections used to transport large amounts of service data include WiBro, HSDPA, and Wi-Fi.

For example, in the case of a streaming service, in the connection step, the mobile terminal device 100 notifies itself to the peripheral device 200 as a server through a Bluetooth communication method, and the peripheral device 200 connected to the mobile terminal device 100 as a server. In Wi-Fi, service data is streamed. Alternatively, after the mobile terminal device 100 configures the device connection through the Bluetooth communication method, the service data may be streamed to the peripheral device 200 through the WiBro method.

The mobile terminal device 100 transmits the service data to the peripheral device 200 in real time according to the service request message 44. Here, when the service data is transmitted to the peripheral device 200 in a streaming manner, the mobile terminal device 100 transmits the service data as a server using a streaming protocol such as RTCP and / or RTSP, and the peripheral device 200 Receives and transmits service data as a client. In the case of a file transfer service, a file may be transferred from a mobile terminal device to a peripheral device using a protocol such as FTP.

As a result, in the present invention, the mobile terminal apparatus 100 becomes a subject of a service and holds data necessary for the service. That is, various local area network connections and broadband network connections can be configured, and serve as servers in a traditional client / server structure.

Subsequently, the mobile terminal device 100 generates a list of searched peripheral devices (S620).

Subsequently, the mobile terminal device 100 determines whether there is a peripheral device suitable for reproducing service data (S630).

Subsequently, if a peripheral device suitable for reproducing service data exists in the list, the mobile terminal device 100 creates a local area network connection with the peripheral device according to a user's request (S640). Accordingly, the device connection between the mobile terminal device 100 and the peripheral device is completed.

Subsequently, the mobile terminal device 100 inquires a broadband network suitable for reproducing the service data based on the generated local area network connection (S650).

Subsequently, when the search result, the mobile terminal device 100 finds a broadband network suitable for transmission of a large amount of service data (S660), it creates a broadband network connection (S670).

Subsequently, the mobile terminal device 100 terminates the local area network connection generated for the device connection (S680).

Thereafter, the peripheral device 200 performs a client role as a device for executing (or playing) a service. The peripheral device 200 connected to the mobile communication terminal device 100 also includes various communication modules for performing a short range wireless communication method and various communication modules for performing a broadband wireless communication method. Will be self explanatory.
