Description

[0001] The present invention relates to a method of connecting a channel using a sound signal,

The present invention is characterized in that coded data is detected in a sound signal input through a microphone, and a data format of the detected data is matched with a CCID (Channel Connection ID) format for channel connection using either the telephone network or the data network And a method for selectively connecting a phone call channel or a data communication channel to an object corresponding to a CCID detected according to a network determined after a network to be connected to a channel is determined between a telephone communication network and a data network based on the CCID format .

Recently, as the smart phone is activated, the recent wireless terminals including the smart phone have significantly improved the computing performance and the degree of freedom in comparison with the conventional feature phone which is limited to the computing performance of the mobile communication modem chip. This improvement in the computing performance and degree of freedom of the wireless terminal means that various data analysis and processing at a level that was possible in the conventional server or personal computer have become possible in the wireless terminal. Especially, the improvement of the degree of freedom makes it possible to provide diversification of application services. For example, in the case of the conventional feature phone, the micro sound signal is regarded as a voice signal for telephone conversation and is set to automatically remove the noise of the input sound signal to improve the call quality. As the degree of freedom improves, it is possible to receive the original sound signal without removing the noise of the micro input signal.

Techniques for inserting a specific signal in the audible frequency domain into a sound signal and reading and using the signal have existed before. A typical example is DTMF (Dual Tone Multi-Frequency) applied to telephone dialing. However, the method of inserting the specific signal in the audible frequency domain into the sound signal has the problem that the inserted signal can be heard by the human ear, thus causing psychological discomfort. In order to solve such a problem, a specific signal to be inserted into a sound signal must be inserted into a noise region. In this case, a wireless terminal such as a conventional feature phone can insert and output a specific signal into a sound signal, It is difficult for a terminal to recognize and read a specific signal included in a noise region of a sound signal to be input.

Meanwhile, connecting a wireless terminal to a network involves a series of user manipulation processes. Examples include entering a phone number or entering a URL. If the wireless terminal is connectable to two or more networks such as a telephone communication network and a data network, the user operation process becomes complicated.

[ The downloaded application 115 is manually or automatically activated. A separate program may be running in advance to automatically drive the application 115, and thus the present invention is not limited thereto.

Referring to FIG. 1, an application 115 of the wireless terminal 100 receives a sound signal input through the sound input unit 105 in a format in which a CCID (Channel Connection ID) format corresponding to the encoded data format is set A setting unit 120 and a rule setting unit 125 for setting a decoding rule for detecting data of the CCID format from the input sound signal.

According to the present invention, among the sound signals input through the sound input unit 105, the sound code in which the data of the CCID format is encoded is referred to as a '0' in a sound signal of an audible frequency or a non- And " 1 " are coded.

In order to generate the sound code, the data to be encoded into the sound signal is made up of a recognizable data format. The format setting unit 120 sets the CCID format And is set and maintained. According to an embodiment of the present invention, the CCID format may be set and maintained in the application 115 in the form of program code, or stored in the memory unit 110 in the form of available format information for the application 115 have.

The CCID format may be a code value of a designated bit size or a combination of two or more code values each having a designated bit size. Preferably, the CCID format includes a network identification value for selecting one of the telephone network and the data network, and a code value having a bit size of a designated identification value for identifying an object to which a channel is to be connected through the selected network, Or a combination of two or more code values each configured with a specified bit size.

The network identification value is a code value for identifying a network to which a channel is to be connected from the telephone network and the data network. For example, when a connectable network is set to two networks including a telephone network and a data network, the network identification value may be a 1-bit code value, and a bit value '0' And the bit value '1' can identify the data network. The data network is connected to a wireless network-based data network connected through a wireless network communication module 108 and a short-range wireless communication module In the case of a wireless communication-based data network, the network identification value may be a 2-bit code value. For example, a bit value '00' identifies a telephone network, a bit value '01' identifies a wireless network-based data network, and a bit value '10' identifies a wireless local area network.

The object identification value is a value that identifies the target device 170 to which the channel is to be connected through the network identified by the network identification value, and is dependent on the network identification value. For example, if the network identification value identifies a telephone network, the target identification value may be assigned to a communication device 170b (e.g., a landline telephone, an ARS server, etc.) to which a telephone communication channel can be connected through a telephone network It can be a telephone number. Or if the network identification value identifies the data network, the target identification value may be an address value (e.g., a URL (e.g., URL) assigned to a communication device 170a Address, etc.), or an index value that identifies a communication device 170a that is capable of connecting a communication channel through the data network. If the target identification value is an index value for identifying the communication device 170a on the data network, the memory unit 110 may store the address value of the target device 170 mapped with the index value. If the application 115 can be connected to a designated management server (not shown) that manages and manages the index value and the address value through the data network, the application unit 115 may access the memory unit 110, The address value of the target device 170 mapped with the index value can be checked through the management server even if the address value of the target device 170 is not mapped. According to another embodiment of the present invention, when the network identification value is identified as a specific network, the target device 170 to be connected through the network is automatically identified (e.g., the target device 170 is fixed Or the service identification value, the service identification value, or the like), the target identification value may be omitted, and the use identification value or the service identification value may be determined based on the target identification value Can play a role.

According to an embodiment of the present invention, the CCID format includes a use identification value for identifying the use of the channel connection, a service identification value for identifying a service to be provided through the connected channel, At least one of a code value of a specified bit size or a combination of two or more code values each having a specified bit size; Lt; RTI ID = 0.0 > a < / RTI >

The use identification value is a code value that identifies a use of connecting the channel with the target device 170 through the network identified by the network identification value among the telephone network and the data network. When the use of the target device 170 to which the channel is connected is fixed to one, the use of the target device 170 is self-explanatory, so that the use identification value can be omitted. Meanwhile, the use identification value may identify the target device 170 to which the channel is connected in addition to the target identification value. For example, if the usage identification value identifies a " billing usage " and the application device 115 is locked with one of the target devices 170 accessible for "billing purposes" The target device 170 that processes the settlement by the " settlement purpose " can be identified. Preferably, the channel connected to the target device 170 by the use identification value may be determined to be one of a non-secure channel and an encryption / decryption based secure channel. For example, if the usage identification value identifies a " billing purpose ", the channel associated with the target device 170 may be a secure channel.

The service identification value is transmitted to the target device 170 corresponding to the target identification value (or automatically identified by the usage identification value) through the network identified by the network identification value among the telephone network and the data network, Is a value that identifies the service to be provided by this connection. When the service provided through the target device 170 to which the channel is connected is fixed to one, the service to be provided through the target device 170 is self-explanatory, so that the service identification value may be omitted. Or the service provided through the target device 170 to which the channel is connected is selected through the user interface, the service to be provided through the target device 170 is selected by the user so that the service identification value can be omitted . However, in the case of automatically identifying one or more services to be actually provided among a plurality of services that can be provided through the target device 170, the service identification value may be provided to the target device 170 through the channel One or more services to be provided may be identified. For example, when the target device 170 is a payment server for processing a payment, there may be a "payment approval service", a "payment cancellation service", a "payment inquiry service" have. Meanwhile, the service identification value may identify the target device 170 to which the channel is connected in addition to the target identification value. For example, if the service identification value identifies a " payment approval service " and the application 115 is fixed to have one target device 170 accessible to provide a service related to payment, The target device 170 that processes the payment by the " payment approval service "

The information input induction value is a value for guiding additional information to be input from a user for providing a service through the channel, and is a value that matches a specific interface among information input interfaces related to a service to be provided by connecting the channel to be. If the information input induction value is included, the matched information input interface may be displayed before the channel is connected to the specific target device 170 through the specific network identified by the network identification value. For example, the information input induction value may include a value for inputting shipping information of a commodity purchase. In this case, an information input interface for inputting the destination information before the channel is connected may be displayed. According to an embodiment of the present invention, the additional information input through the information input interface may be converted into a transmission format of the network corresponding to the network identification value and transmitted to the target device 170 after the channel connection process or connection. Here, the transmission format is a format designated to receive the additional information in the target device 170, and preferably means a data communication protocol in which the target device 170 can receive the additional information in the case of a data network. And a DTMF signal in the case of a telephone network.

Meanwhile, the memory unit 110 may store basic transmission information to be transmitted to the target device 170 at the time when the channel is connected. Preferably, the basic delivery information may be mapped to at least one of the object identification value, the usage identification value, and the service identification value. The basic delivery information may be converted into a transmission format of the network corresponding to the network identification value and transmitted to the target device 170 after the channel connection process or connection. For example, in the case of a data network, the basic delivery information may be stored in an address value of a data network, for example, for connecting a communication channel with a specific target device 170, for setting a specific purpose, And may include parameters of the GET method to be added. Alternatively, when the channel connected to the target device 170 is an encryption / decryption-based secure channel, the basic transmission information may include an encryption / decryption key for connecting the secure channel. On the other hand, in the case of a telephone network, the basic delivery information may be an optional value (e.g., " telephone number " + "# 123 ") in the form of a DTMF signal appended to the telephone number. For example, if the target device 170 to which the telephone call channel is connected is the ARS server, the basic delivery information may include a menu to be input for receiving a specific service from the wireless terminal 100 after the call channel is connected to the ARS server Button. ≪ / RTI >

According to an embodiment of the present invention, the basic delivery information may be the same information as the additional information to be input through the information input interface. For example, when the destination address is input through the information input interface, the input destination address may be stored in the memory unit 110 in the form of basic transfer information, And can be used as additional information to be used for the service. In this case, even if the detected data includes the information derivation value, it is possible to use the stored basic transmission information without displaying the information input interface and inputting additional information.

The condition identification value is a value for identifying a condition for connecting a channel with a specific target device 170 through a specific network identified by the network identification value. When data of the CCID format is detected and a channel is connected It is optional. However, when the CCID format data is detected and the channel is not connected and the channel is connected for a certain period of time, it is a value to determine a time to connect the channel. For example, when the data of the CCID format is detected and the user drives a specific program among the programs provided in the wireless terminal 100 or activates a specific screen, the condition identification value is identified by the network identification value Lt; RTI ID = 0.0 > 170 < / RTI >
