Description

{Method for recognizing things and communicating with things automatically}

The present invention relates to a method in which a wireless terminal automatically recognizes an object and performs communication in a wireless communication system. More specifically, the present invention relates to a method in which a user having a wireless terminal can easily receive a service from an object.

In the wireless communication environment to date, scheduling and carrier sense multiple access / collision avoidance (CSMA / CA) schemes are mainly used. Scheduling is mainly used for a mobile communication base station to efficiently allocate resources to a terminal without collision. CSMA / CA is used in an asynchronous communication method such as WIFI, and is used when several STAs compete to communicate with an AP. Both methods are communication environments with a central control station.

On the other hand, in the wireless distributed communication environment, an efficient collision avoidance method for a large scale connection does not yet exist. In particular, collision avoidance in a communication environment targeting a large mobile terminal rather than a large fixed terminal is very difficult.

Wireless distributed systems that require large-scale connectivity can be commercialized only if collision avoidance is available. Since there is no control station in the wireless distributed system, scheduling by the control station may not be possible. In addition, since CSMA / CA is used in an asynchronous manner, it may not be appropriate in a synchronous manner. In particular, it is difficult for more than 50 people to use WIFI simultaneously using CSMA / CA. Typically, WIFI APs are installed in offices with an estimated 20-25 people.

Accordingly, there is a demand for development of a technology that can effectively avoid collisions in a synchronized wireless distributed communication environment requiring large numbers of thousands or tens of thousands of connections.

The present invention can provide a method in which a terminal automatically recognizes a thing and the terminal immediately communicates with the thing.

In addition, the present invention can provide a thing that the user terminal recognizes and controls.

In addition, the present invention may provide a method of embedding a driver or program in a thing and downloading it from the thing wirelessly.

In addition, the present invention may provide a method of operating an object at low power using a tone channel and a tone slot pattern.

In addition, the present invention can provide a method for updating a driver or a program embedded in a thing.

According to an embodiment of the present invention, a terminal may automatically provide a method of automatically recognizing and controlling a thing. In this case, a method for automatically recognizing and controlling an object may include: embedding a file for recognizing and controlling an object, downloading a file embedded by the terminal through a wireless communication, and using a file downloaded by the terminal. It may include the step of recognizing the object.

In addition, according to an embodiment of the present invention, a terminal may provide a method of performing control by re-recognizing a previously recognized object. The terminal re-recognizes a thing to perform a control method in which the terminal wirelessly transmits a wake tone signal, a tone slot pattern, or both a wake tone signal and a tone slot pattern, the terminal wirelessly searching for the thing, the search result This control may include controlling the thing if it exists and giving up control if the thing does not exist as a result of the search.

In addition, according to an embodiment of the present invention, when the terminal wirelessly controls the thing, it is possible to provide a method for controlling the thing by receiving a control signal. A method of controlling a thing by receiving a control signal includes calculating a received power or path loss of the signal, and allowing to control the thing only if the received power is greater than the threshold or the path loss is less than the threshold. Can be.

Further, according to an embodiment of the present invention, when the terminal wirelessly controls the thing, it may provide a method for controlling the thing by receiving a control signal. In this case, the method of controlling a thing may include registering a transmission ID of the terminal to the thing, transmitting a signal for controlling the thing by the terminal with its ID, and receiving the control signal. If the ID is allowed to control, if the information is not registered may include the step of not allowing the control.

According to the present invention, the terminal automatically recognizes a thing and performs communication, so that a service for the thing can be provided quickly and easily.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the accompanying drawings, the substantially identical components are represented by the same reference numerals, and thus redundant description will be omitted. In addition, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

In the following description of embodiments of the present invention, when it is determined that a detailed description of a known structure or function may obscure the gist of the present invention, a detailed description thereof will be omitted. In the drawings, parts irrelevant to the description of the present invention are omitted, and like reference numerals denote like parts.

In the present invention, when a component is "connected", "coupled" or "connected" with another component, it is not only a direct connection, but also an indirect connection in which another component exists in between. It may also include. In addition, when a component "includes" or "having" another component, it means that it may further include another component, without excluding the other component unless otherwise stated. .

In the present invention, the terms "first" and "second" are used only for the purpose of distinguishing one component from other components, and do not limit the order or the importance between the components unless otherwise specified. Accordingly, within the scope of the present invention, a first component in one embodiment may be referred to as a second component in another embodiment, and likewise, a second component in one embodiment may be referred to as a first component in another embodiment. It may also be called.

In the present invention, the components distinguished from each other to clearly describe each feature, and does not necessarily mean that the components are separated. That is, a plurality of components may be integrated into one hardware or software unit, or one component may be distributed and formed into a plurality of hardware or software units. Therefore, even if not mentioned otherwise, such integrated or distributed embodiments are included in the scope of the present invention.

In the present disclosure, components described in various embodiments of the present disclosure are not necessarily required components, and some of them may be optional components. Therefore, an embodiment consisting of a subset of the components described in one embodiment is also included in the scope of the present invention. In addition, embodiments including other components in addition to the components described in the various embodiments are included in the scope of the present invention.

In connection with the present invention, the existing CSMA / CA could only be used in an asynchronous communication system. In this case, in the wireless distributed communication system of the present invention, the contention substitute channel may be used so that the CSMA / CA may be used in the synchronization system. For example, the primary channel and the secondary channel may be paired. The original data channel may have a wide bandwidth of several MHz. In this case, the main communication band may be used as the data channel as it is. Competing channels use narrowband signals. A frequency tone can be used as a narrow band signal, and since the frequency tone has a bandwidth of several kHz to several tens of kHz, it has a bandwidth less than 1/100 of the broadband bandwidth. As an example, if the 1MHz band is configured with a 10kHz tone channel and a 990kHz data channel, the maximum data channel utilization is 99% under the assumption that there is no collision. This can be very advantageous when using CSMA / CA in the same band, compared to 50% maximum channel utilization. In this case, as an example, the secondary channel may be allocated immediately adjacent to the primary channel. In addition, as an example, the subchannel may be allocated away from the main channel, and is not limited to the above-described embodiment.

That is, in an environment where a plurality of terminals (e.g. thousands or tens of thousands) of terminals coexist, the channel efficiency of the plurality of terminals may be set differently from that of the data transmission channel, thereby improving frequency efficiency.

In addition, as an example, UEs may compete in a slot before a slot to be used. In more detail, if UE A decides to use slot s of the primary channel, UE A may perform competition in advance in slot s-1, which is a competition agency channel. At this time, the terminal A, if the subslot number in the slot of the contention channel is N, it can perform carrier sensing (carrier sensing) to the previous subslot of the selected subslot. If there is no signal detected as a result of the execution, a contention tone signal is transmitted from the selected subslot to the last subslot and data is transmitted in slot s of the main channel. In this case, as an example, when there is a signal detected as a result of the execution of the terminal A, the terminal A may determine that it is lost in contention and may not transmit any signal in the tone channel and the main channel. However, the above-described sub slot allocation is only one embodiment and is not limited to a specific number. That is, the terminal allocated the lowest number of subslots may transmit a contention signal after carrier sensing and perform data transmission on the primary channel.

In this case, as an example, the signal of the competition agency channel may use a frequency tone signal, and in this case, the frequency band may be used the least. In this case, hereinafter, the contention signal is assumed to be a tone signal. However, the competition signal may be set differently, and is not limited to the above-described embodiment. Through the above-described competition, terminals selected the same slot can avoid collision. For example, in the above-described situation, the UEs having selected the same slot among 500 could avoid collision again.

In the present invention, slot clearing means that a terminal continuously transmits a contention signal starting from subslot 0 in a previous slot s-1 of a competing substitute channel in order to continuously use the slot s without collision. It can mean preventing attempts. That is, it may mean the operation as described above, the following description will be described on the premise.

Also, for example, many electronic and electrical products may be connected with integrated terminals such as smart devices. However, a process of connecting an object with an integrated terminal such as a smart device may be complicated. For example, in order for a smart device and a thing to be connected to each other, a wireless interface needs to be determined. At this time, mainly WIFI or Bluetooth may be used. Also, as an example, the smart device needs to search for an application for the thing and install the application. In addition, the smart device may execute the application and wait for the application to recognize the bird and then control the object after the connection. Here, when the application recognizes the thing, the user of the smart device needs to control the smart device (eg, after the user has read the manual of the thing, the user must press the terminal button of the thing several times). The user of the device needs to perform an additional operation in consideration of the characteristics of the thing and the surrounding situation. Therefore, the users of the smart device may have many steps to perform, and the usage efficiency may be reduced.

As another example, the smart device may control the thing after being connected via WIFI or Bluetooth. That is, the user of the smart device needs to perform an operation of manually connecting WIFI or Bluetooth. In view of the foregoing, a method for automatically connecting a smart device to a service for providing a service may be required, which will be described.

For example, in order for a mobile terminal to immediately recognize a nearby object and be connected and receive a service from the object, there is a need for the terminal and the thing to directly communicate with each other. In this case, the terminal may directly communicate with the thing in various ways. As an example, the terminal may perform direct communication using the existing WIFI or Bluetooth.

In addition, as an example, the terminal is competing based on the above-mentioned and reference 1 (Application No. 10-2017-0026778, Reception No. 1-1-2017-0207822-47, Collision Avoidance Method in Synchronous Wireless Communication System, Korea). Distributed communication using a method can directly communicate with a thing. For example, the terminal and the thing have a common communication modem, and the terminal may search for the thing based on the common communication modem. In addition, as an example, distributed based on the above-mentioned and reference 2 (Application No. 10-2018-0014682, Application No. 1-1-2018-0131792-95, Service method using multiple channels in a synchronous TDMA system, Korea) You can search for things through communication. In this case, the terminal may search for the thing through the slot and the channel based on the above. In addition, as an example, when the terminal recognizes a thing in the following, it may mean that the terminal prepares necessary preparation for receiving a service from the thing. That is, when the terminal communicates with the thing and installs a driver or program suitable for controlling the thing, the terminal may recognize the thing.

In more detail, in order for the terminal to immediately recognize the object, it is necessary to directly receive a driver file, a program file, or a program installation file for controlling the object by the wireless device directly from the object. However, things may not directly provide a driver or a program necessary for controlling themselves. For example, in order to wirelessly provide a driver or a program for controlling things by a thing, a large capacity semiconductor memory and a means for wireless communication may be required. That is, the existing objects do not have the above-described configurations, and thus, they cannot directly provide information about a driver or a program by wireless. However, as an example, the above-described components may be included in the thing in consideration of the cost of the memory and the wireless communication modem. That is, the objects may include a modem for wireless communication and may embed information (e.g. driver file, program file, program installation file) necessary for object recognition. In this case, when the terminal requests the corresponding file to the thing through wireless communication, the thing may provide the corresponding file through wireless communication.

Specifically, referring to FIG. 1 (a), the terminal may access a thing to be provided with a service. In this case, the terminal may check information on the thing. For example, the information on the thing may be at least one or more of a product name, a type, and a model name, and is not limited to the above-described embodiment. For example, the terminal may recognize the information about the thing based on the information input from the user. In other words, the user needs to check the model name by accessing the object. Thereafter, the terminal may receive information about the object (e.g. driver file, program file, program installation file) through a communication network (e.g. internet app store, internet web page). For example, the user of the terminal may receive related information by searching an application or searching an installation file of a corresponding model. Thereafter, the terminal may download and install the application or the installation file. In this case, the terminal may check an object operation and a manual for recognizing the object and perform control on the object. That is, a plurality of procedures may be necessary as described above.

At this time, as an example, when the thing-related information is stored in the thing and wireless communication is possible, the terminal searches for the thing (S121) and receives information about the thing (eg driver file, program file, program installation file). can do. That is, the thing may embed the file for recognizing and controlling the thing in the memory and provide the same to the terminal. For example, referring to FIG. 2, the terminal and the thing may include a common communication modem and a configuration for controlling the same. In addition, the thing may also include a control device for providing the files stored therein. The embedded files may be a driver file, a program file, or a program installation file for controlling the thing as a file for information on the thing as described above.

For example, the driver file may provide a driver required by a basic program or an OS installed in the terminal. In this case, when a corresponding driver is installed in the terminal, the terminal may receive a service for the corresponding object from an existing program. As a specific example, referring to FIG. 3, when the remote controller basic program is installed in the terminal, the terminal may receive a driver from the air conditioner. In this case, the terminal may search for surrounding objects (S311), and may select an air conditioner therefrom. The terminal may download and install a driver after selecting the air conditioner and may automatically recognize it. Thereafter, the terminal may control the air conditioner using the remote controller basic program and the corresponding driver. In the above-described embodiment, the air conditioner has been described with reference to the air conditioner, but this is only for convenience of description and is not limited to the above-described embodiment. That is, the same may be applied to other objects, and is not limited to the above-described embodiment.

Next, when the related program is not installed in the terminal, the terminal may wirelessly download the program file or the program installation file from the corresponding object and install the program file. For example, referring to FIG. 3 (b), a drone may be considered as a terminal. However, this is only one example and may be equally applied to other objects. In this case, the drone may embed a program for controlling the drone. In this case, the terminal may directly download a program for controlling the drone wirelessly from the drone. In detail, the terminal may search for a drone as a surrounding object. In this case, the terminal may directly download the program from the corresponding drone and install it and automatically recognize the program. Thereafter, the terminal may select and control the corresponding drone. For example, the terminal and the drone may include a common modem. In addition, as an example, if there is a general purpose drone control terminal, the general purpose control terminal can easily download the installation file from the corresponding drone to control the drone.

In addition, as an example, when the terminal automatically recognizes and controls an object, the terminal may first wirelessly search for neighboring objects. In this case, when the terminal searches for neighboring objects, the terminal may select a thing to be connected from among the found ones. The terminal may receive information on the thing (e.g. driver file, program file, program installation file) from the selected thing. In this case, as an example, the thing may broadcast information about the thing, and the terminal may recognize the thing by using the broadcasting information.

In addition, as an example, as described above and reference 3 (Application No. 10-2018-0021100, Application No. 1-1-2018-0187211-36, Method of operating a terminal using a tone channel in a synchronous time division multiple access system, Korea) A wake up tone channel can be used on the basis. For example, an object equipped with a battery may be efficiently operated at low power. For example, the above-described object may be awake based on a wake tone signal while maintaining a sleep mode. In this case, the wake tone channel may mean a tone channel for awakening an object from among the tone channels as described above. That is, the case where the use of the tone channel is used as the awake of the thing can be considered. In this case, the awakened object may broadcast its information on a preset wireless channel or check whether there is a packet delivered to the awakened object. In this case, when the awakened thing broadcasts the information of the thing, the terminal may recognize the thing by receiving the broadcast information.

For example, referring to FIG. 4, the terminal may transmit a wake tone. In this case, as described above, the terminal may transmit the wake tone to the thing through the wake tone channel, and the thing may be awake based on the wake tone channel. When the thing is awake, the thing may broadcast information about the thing through a wireless channel. In this case, the information on the thing may be the above-described information. Thereafter, the terminal may receive the information about the broadcasted thing and acquire the thing information. (S413)

In addition, as an example, the terminal may transmit a packet in which the source address is set as its own address and the address of the awakened object is set as the destination address after transmitting the wake tone. . In this case, the awakened object may transmit a response packet for the received packet to the search terminal when the destination address of the received packet matches its own address. In this case, the response packet may include information about the thing, and the terminal may obtain the information about the thing. For example, referring to FIG. 4 (b), the terminal may transmit a wake tone through the wake tone channel. In this case, the terminal may transmit a packet having its own address as a source address and an address of the awakened terminal as a destination address. In this case, the thing may receive a packet having itself as a destination address. Thereafter, the thing may transmit a response packet to the terminal to the terminal. Thereafter, the terminal may acquire information about the thing through the response packet, and may operate based on the above description. (S425)

For example, when the terminal searches for a thing based on the above description, the terminal may search for a plurality of things. In this case, in addition to the thing that the terminal wants to search, other things may wake up to broadcast their information for a predetermined time and perform an operation on whether there are no packets delivered to the user. Therefore, a thing that the terminal does not intend to control may consume the battery unnecessarily. For example, when using the wake tone channel described above and in reference 3, only a desired object may be awakened using the tone slot pattern. In Reference 3, the tone slot pattern may mean that information is sent to subcarriers other than the 0 subslot of the competing substitute channel, that is, the competing tone channel. Here, sub slot 0 is used for slot clearing. However, as described above, the wake tone channel does not need to exclude the 0 subslot. Accordingly, in the present invention, the tone slot pattern may be formed in all sub slots including sub slot 0 in the wake tone channel instead of the competing tone channel. As such, the tone slot pattern is a competitive tone channel described in Reference 4 (Application No. 10-2018-0027675, Application No. 1-1-2018-0236883-25, How to Use Efficient Tone Channels in a Wireless Distributed Communication System, Korea). Alternatively, the transmission may be transmitted through a wake tone channel described in Reference 3 or a tone channel given meaning to slots and subslots described in Reference 3, and is not limited to the above-described embodiment. That is, when transmitting a tone channel to automatically recognize a thing, only a specific thing may be recognized, and the present invention is not limited to the above-described embodiment.

In detail, the terminal may transmit the wake up tone and transmit a signal based on the tone slot pattern. As an example, referring to FIG. 5A, the wake tone signal may be continuously transmitted during a frame of 1 second in length. However, the wake tone signal may be transmitted in another form, and is not limited to the above-described embodiment. In this case, the terminal may transmit the tone slot pattern after the wake tone signal is transmitted. In this case, the object may further receive a tone slot pattern after receiving the wake tone signal. After the wake-up tone signal, the thing may be awake only when the tone slot pattern is a tone slot pattern associated with itself to broadcast information about the thing, or may receive a packet from the terminal.

As a specific example, the terminal may transmit the tone slot pattern associated with the air conditioner as an object after the wake up tone signal is transmitted. In this case, although the plurality of things may receive the wake tone transmitted by the terminal, only the air conditioner having the same tone slot pattern among the plurality of things may be awakened to communicate with the terminal. That is, the air conditioner may broadcast information of the air conditioner or receive a packet from the terminal.

For example, referring to FIG. 5 (b), the terminal may transmit a tone slot pattern related to an air conditioner after transmitting a wake tone signal. Thereafter, the air conditioner may check the tone slot pattern received after the wake up tone. In this case, when the tone slot pattern coincides with the pattern of the air conditioner, the air conditioner may be awake to check whether there is a packet that broadcasts or receives information of the air conditioner. For example, in the case of a TV as a peripheral object, it may operate as shown in FIG. 5C. The terminal may transmit the tone slot pattern associated with the air conditioner after transmitting the wake tone signal. In this case, the TV may check the tone slot pattern received after the wake up tone. (S522) Since the TV does not match its pattern and tone slot pattern, the TV may remain asleep. That is, the terminal may transmit a tone slot pattern for identifying the corresponding object after transmitting the wake tone signal. In this case, a plurality of things may exist around the terminal, and the terminal may identify a specific thing through a tone slot pattern.

As another example, even when the terminal acquires relevant information about a thing and already installs a driver or a program, a wake tone signal and a tone slot pattern may be used to awake and control the thing. For example, the terminal may need additional information through direct communication with the thing. Specifically, the terminal may not always provide a service through the thing, so it is necessary to indicate whether the service is active. For example, the user of the terminal may control the terminal to directly communicate with the thing. In this case, the terminal may operate as described above based on the wake tone signal and the tone slot pattern.

Also, as an example, the terminal may automatically select a thing to control from among a plurality of things. The terminal may automatically select a thing based on a higher layer (program or application) setting. For example, a preset program may exist in the terminal, and an object may be automatically selected based on the preset program. For example, when there is a machine that automatically feeds an animal or waters a plant, the program of the terminal may automatically select and control an object periodically. Specifically, referring to FIG. 6, the terminal may set the program to be executed periodically. For example, in FIG. 6, if the feeding program automatically performs a feeding operation, this is only one example and is not limited to the above-described embodiment. Thereafter, the terminal may transmit the wake up tone through the wake up tone channel. That is, the program of the terminal may periodically change the corresponding object to the awake state by using the wake tone. Also, as an example, the tone slot pattern is transmitted based on the above-described period, and thus, the thing may be awakened in the above-described period. That is, the tone slot pattern may be set in consideration of the period, and the thing may be awakened based on a preset period through the tone slot pattern in which the period information is considered, and is not limited to the above-described embodiment. Thereafter, the object that has received the wake tone signal may be awake to broadcast its own information or check whether its own packet exists. That is, the feeding machine and the surrounding objects may be awake to broadcast their information. In this case, the terminal may receive the broadcasted thing information and then select the corresponding thing (or things). That is, the terminal may select a feeding machine after receiving the broadcasted object information. Thereafter, the terminal may control the thing (or objects) through direct communication. That is, the terminal may transmit a command for feeding the feeding machine to the feeding machine, and control the operation of the thing based on this.

 As another example, the terminal may wirelessly download a file from an object and then perform a task required for recognition using the file. For example, a task required for recognition may mean installing a driver or program suitable for controlling a corresponding object in a terminal. Here, although the terminal recognizes and controls the thing, it may be performed by using the downloaded and installed program, but it may be more efficient to download the driver than to download all the programs. That is, a general-purpose program is installed in the terminal, and the driver downloaded and installed therein can be applied to the program to perform control. For example, if a universal remote control program is installed in the terminal, the air conditioner driver can be downloaded from the air conditioner to operate the air conditioner, and the TV driver can be operated by downloading the TV driver from the TV.

Also, for example, when operating based on the above description, authentication or password setting may be required in the object recognition process. For example, security and other problems may occur when a thing is controlled by another terminal that is not authenticated. To this end, when the terminal requests the thing to download a file embedded in the thing, the thing may request a password from the corresponding terminal. In addition, the terminal includes a password in a packet controlling the thing and transmits it wirelessly, and the thing may allow control only when the password is checked and authenticated in the packet. That is, the terminal and the thing may perform a procedure for authentication, and control authority of the thing may be given to the terminal only when authentication is completed. For example, all terminals may recognize the thing, but controlling the corresponding thing may be possible only by a specific terminal authenticated.

In addition, as an example of a method of maintaining security, the password itself may be transmitted, but if the information transmitted using the password is scrambled with the PN code, the security may be further enhanced. Also, for example, it may be possible to change the form of security. Specifically, after the user purchases the thing, when the initial password is set, other security or authentication methods other than the password may be required.

In this case, as an example, whether to allow the control of the thing may be determined based on the reception power or the path loss of the signal received by the thing. More specifically, the thing may calculate the received power or path loss for the received signal. In this case, the thing may allow control of the thing only when the calculated received power is larger than the threshold value, or when the path loss is smaller than the threshold value. That is, the thing may allow control of a terminal that is at a certain distance or close to the thing by using a signal. For example, the range of the wireless distributed communication system may be set wider than the area where the terminal or the thing is located. However, the user or system of the terminal can determine the range of use by granting control authority only to signals up to a certain distance. For example, when a resident of another house wants to control a TV of my home, the reception power of a control signal arriving at the TV is smaller than a threshold so that the TV cannot be controlled. At this time, a user who purchases a TV as a user of an object may set a reception power threshold or a path loss threshold on the TV to prevent control by another person. For example, referring to FIG. 7A, a thing may receive a control signal from a terminal. In this case, the object may calculate a received power or a path loss of the received control signal. If the received power is greater than the threshold or if the path loss is less than the threshold (S713), the thing may be determined to be a nearby terminal and allow control. For example, when the reception power is smaller than the threshold or the path loss is larger than the threshold (S713), the thing may not allow control. (S715)

As another example, the control of the thing may be performed based on the terminal ID. For example, the terminal ID may be registered in the thing. That is, if an ID of a terminal capable of controlling a thing is registered in the thing, the terminal may transmit a wireless packet including its ID to the thing. Through this, the thing may check whether the corresponding packet is an authenticated terminal through ID information of the received packet, and may allow control based on the ID. For example, referring to FIG. 7B, a controllable terminal ID may be registered in a thing. (S721) When the thing receives the control signal (S722), the thing may determine whether the ID included in the control signal coincides with the ID in which the information is registered. In this case, when the ID registered in the control signal includes the thing, the thing may allow the control. On the other hand, when the ID registered in the control signal does not include, the thing may not allow the control. (S725)

Also, as an example, initial registration of a thing may be considered. For example, referring to FIG. 7C, an object may first receive a control signal. For example, when a user first purchases an object or is used for the first time after the object is reset, the object may receive a control signal for the first time. Here, the thing may automatically register the ID of the terminal included in the received control information as the control permission terminal registration ID. That is, it is possible to provide convenience for user use by recognizing and registering the first user. At this time, when the thing receives the control signal (S733), the thing may determine whether the ID included in the control signal matches the ID registered with the information. In this case, when an ID registered in the control signal is included, the thing may allow control. On the other hand, when the ID registered in the control signal does not include, the thing may not allow the control. (S736)

Also, as an example, the terminal may perform additional control on the thing as well as the recognition of the thing. For example, the terminal may automatically execute a program related to the thing, and automatically receive the current state of the thing and display it on the interface screen of the program. Through this, it is possible to efficiently provide the state information and the service of the thing to the user of the terminal.

Specifically, the terminal may recognize and control the object once recognized without having to download a file embedded in the object. In detail, referring to FIG. 8, the terminal may request control of an already recognized object. That is, the user of the terminal may request control of a thing already recognized through the terminal. Thereafter, the terminal can search for the surrounding objects by wireless. In this case, when the thing exists (S813), the terminal may obtain a control right for the thing and provide a service. On the other hand, when the thing does not exist (S813), the terminal may provide service unavailable information to the user and terminate the service. Here, the method of searching for the thing may use the same method as the method of searching for the thing in order to recognize the thing for the first time.

As another example, information (e.g. driver, program) embedded in a thing may be updated. At this time, the update needs to be performed in connection with the terminal as well as the thing. For example, the terminal may receive a version information by requesting a version of the information (e.g. driver, program) from the thing. Thereafter, the terminal may determine whether to update the corresponding information by using the received version information. In this case, the terminal may receive updated information about the thing by using an existing communication network or another communication network. The terminal may transmit update information about the thing wirelessly received to the thing. The thing may update the driver or program file received from the terminal and embed it.

More specifically, referring to FIG. 9, the terminal can receive version information by requesting version information from surrounding objects. In this case, the terminal may check whether the received version information is the latest information. In this case, if the received information is the latest information, the terminal may end the update procedure. On the other hand, if the received version information is not the latest information, the terminal may transmit a driver or program to the thing. For example, the terminal may receive the latest driver or program for the corresponding object from the device, and may transmit the same to the thing. Thereafter, the thing may update and embed the existing file by using the received driver or program. (S914)

Also, as an example, when the terminal wirelessly searches for a thing, the terminal may receive information from the thing based on a certain format. In this case, the terminal may determine the type of the thing based on the received information about the thing, and perform a recognition procedure for the thing. For example, the terminal may perform an initial search for the thing and may obtain the thing initial information based on the initial search. For example, the initial object information includes the name of the thing, the type of the thing, the model name of the thing, the product number of the thing, the types of the internal files, the available wireless communication information, the basic program type associated with the user terminal, the version, the current product state information, and the like. At least one or more of the supported language information may be included. In addition, the types of embedded files refer to a driver or a program embedded in the thing, and the usable wireless communication information may mean information on the communication means provided by the thing. In this case, as an example, the thing may include one or more communication means, and available wireless communication information may be utilized. For example, the product number of the thing may be used. In this case, after the terminal installs the driver or the program of the object, the terminal may be automatically registered in the program in which the product number is installed.

In addition, as an example, files embedded in each thing may be produced in languages of each country. In particular, when the program is installed, the program menu may be displayed in the language of the corresponding country. For some things, however, multiple languages will need to be supported. In this case, for example, as many drivers or program files as the number of supported languages may be embedded in the thing. As another example, a driver or a program file may be commonly created and embedded in a thing regardless of a language, and language-related files may be additionally embedded in the thing as many as the number of supported languages. As described above, the memory size may be effectively reduced. Can be. That is, when the terminal receives a driver or a program for a thing, the terminal may also download a language-related file and support the languages of each country. This allows the user to view the program in the desired language.

As another example, referring to FIG. 10, the terminal may provide a method for recognizing an object based on the above description. For example, conventionally, the terminal needs to access a thing that a user wants to receive a service (S1011), and check the product name, type, and modem name of the thing. Thereafter, the terminal may receive a file about the thing through a communication network (e.g., an internet application store or a web page). In this case, as an example, the terminal may search for the corresponding file through the communication network (S1014) and then install the target file or application after downloading. Thereafter, the terminal checks an operation and a manual for recognizing the object (S1016), and accesses the object through authentication such as a login. Thereafter, the terminal may register a product number of the thing (S1018) and perform an additional operation for product setting. (S1019)

On the other hand, when the object is automatically recognized as described above, the terminal may operate based on FIG. 10 (b). In this case, the terminal may search for nearby objects (S1021) and select a thing from the selected thing. In this case, the terminal may automatically install a related file (S1023), and automatically recognize a thing and register a product number, as described above. In addition, as an example, the terminal may perform an additional task for product setting, as described above. (S1025)
