Method and device for transmitting and receiving information between devices in a wireless communication system

The present disclosure relates to a method and apparatus for transmitting and receiving information between devices in a wireless communication system.

The Internet is evolving from a human-centered connection network where humans create and consume information, to an Internet of Things (IoT) network that exchanges and processes information between distributed components such as objects. Internet of Everything (IoE) technology, which combines big data processing technology through connection with cloud servers, etc. with IoT technology, is also emerging. In order to implement IoT, technology elements such as sensing technology, wired and wireless communication and network infrastructure, service interface technology, and security technology are required. , M2M), and MTC (Machine Type Communication) are being studied.

In the IoT environment, an intelligent IT (Internet Technology) service that collects and analyzes data generated from connected objects and creates new values in human life can be provided. IoT is a field of smart home, smart building, smart city, smart car or connected car, smart grid, health care, smart home appliance, advanced medical service, etc. can be applied to

On the other hand, terminals such as smartphones and tablet PCs are connected to cellular data networks such as Wi-Fi, Long Term Evolution (LTE), and Wideband - Code Division Multiple Access (W-CDMA), and for example, arbitrary information such as weather information, etc. Data information may be obtained from a server that provides a data service. In the process of acquiring data information in this way, power of the terminal may be consumed and charging may occur for data network connection.

1 is a diagram illustrating an example in which a terminal is connected to a data server providing weather information and receives weather information.

In FIG. 1 , the terminals 103 , 105 , 107 , and 109 transmit a weather information request message including their location information to the server 101 ( 111 , 113 , 115 , 117 ), and the server 101 receives each Weather information corresponding to the location of the terminals is provided to each terminal (121, 123, 125, and 127).

In addition, as an example of receiving other data information, the terminal may receive its current location information by using GPS or by communicating with a server without GPS.

A method of confirming the current location using GPS, for example, may operate as follows. That is, the terminal transmits the latitude and longitude information obtained using the GPS to the server, and the server returns address information corresponding to the latitude and longitude to the terminal. For reference, converting specific address information into a form of latitude and longitude information is called geocoding, and on the contrary, converting latitude and longitude information into a specific address form is called reverse geocoding.

As an example, a method of confirming the current location without GPS may operate as follows. The terminal transmits a message including information on one or more currently detected Wi-Fi APs (Access Points) or cell identifier (Cell ID) information of the cellular data network to the server, and the server transmits the location information associated with the received data. It can be provided to the terminal. In this case, the provided location information may be latitude and longitude information or geographic address information of the corresponding terminal. 2 is a diagram schematically illustrating a general process for a terminal to receive information from a server in a wireless communication system.

In FIG. 2, it is assumed that two terminals 210 and 220, and each terminal includes an information receiver 1 (211/221) and an information receiver 2 (212/222), and each of the information receivers provides information necessary for them. It is directly received from the providing information provider 1 (231) and information provider 2 (232). For reference, here, the information receiver may be a service entity that provides applications, widgets, and other various services included in the terminal to the user, and the information provider may be a server that provides each information.

Meanwhile, Bluetooth Low Energy (BLE or Bluetooth Smart) technology is one of low-power network technologies. In BLE, one or more peripheral devices advertise a signal for notifying their existence, and the central device performs a discovery operation to recognize the existence of the peripheral device. The central device discovering the advertisement signal of the peripheral device through the discovery operation may connect to the peripheral device and use various functions through the peripheral device.

For example, if the peripheral device is the user's smart phone and the central device is the door lock device for the door, the door lock that detects the advertisement signal of the smart phone performs a connection with the smart phone, and through the connection, the key included in the smart phone Checks whether the key has a valid permission for access or not, and unlocks the corresponding door. Conversely, the user's smart phone may be the central device and the door lock may be a peripheral device. In this case, the smart phone may unlock the door lock after determining whether the corresponding door lock can be unlocked.

3 is a view for explaining an operation example of a general smart door lock device supporting BLE.

The terminal 303 supporting BLE is always transmitting an advertisement signal (1), and when the user touches the door lock 301 (2), the door lock 301 detects the advertisement signal, and the key included in the advertisement signal. By authenticating and unlocking the door lock (3), all processes for opening the door lock are completed (4).

There are cases where the data information provided by the server to the terminals is the same. For example, weather information or location information (latitude/longitude information) of a specific area is representative. That is, when terminals located in a specific area request the server for weather information or location information of the corresponding area at a similar point in time, the weather information or location information provided by the server to the terminals located in the corresponding area are all the same. The similar time point may be a time point at which information to be provided from the server to terminals located in the same condition is still valid. That is, the weather information or the current location information of the terminal is not only the same information to terminals located in the corresponding area, but also requests the corresponding information from the server because in many cases, the same weather-related application or widget service is basically installed in each terminal. There are many terminals that do. In addition, specific information that is frequently needed by a large number of users, such as weather information or location information, is periodically updated to display the latest information, or when conditions such as executing to use a service using weather information occur also update. When all terminals equipped with such a weather information update service try to update the corresponding information on a regular basis, the network load of the telecommunication service provider and the server of the information provider providing the corresponding information are temporarily overloaded.

On the other hand, in the case of a door lock system using Bluetooth, when a central device is a door lock device, current is consumed to discover an advertisement signal, so it is common to perform an advertisement signal detection operation only when a specific trigger occurs. However, in this case, a specific trigger may be difficult. For example, when the door lock performs the discovery operation only when the user touches the handle of the door lock, it may be difficult to perform the trigger operation for unlocking the door lock, such as when the user is holding a heavy object in both hands. In addition, if the terminal, which is a peripheral device, must always transmit an advertisement signal in order to use the Bluetooth door lock, unnecessary power consumption and security problems of the terminal device may be caused.

Prior to a description of an embodiment according to an aspect of the present disclosure, a basic concept of an aspect of the present disclosure will be briefly described.

The present disclosure advertises a signal including predetermined information to adjacent devices when a specific condition is satisfied in a corresponding device in device-to-device communication, the adjacent device receives the advertised signal, and includes a signal included in the advertised signal. This is to use the predetermined information.

In the first aspect of the present disclosure, the specific condition is a case in which the predetermined information is preset specific information such as weather information or location information, and when the device acquires the predetermined information, the predetermined information is valid can be For example, if the terminal acquires weather information from the server and it is determined that the weather information is valid for a predetermined period, the terminal transmits the weather information in the form of an adjacent advertisement signal to an adjacent area. Accordingly, the adjacent terminal receiving the advertisement signal can use the weather information included in the advertisement signal. In addition, the adjacent terminal may again advertise the weather information to the adjacent area for a predetermined validity period. In this way, the same information, such as weather information, can be transmitted/received to/from a neighboring terminal rather than a server to terminals located in a specific area. Detailed embodiments of the first aspect of the present disclosure will be described later.

Meanwhile, in relation to the second aspect of the present disclosure, the specific condition may be that two devices are adjacent to each other within a predetermined distance. For example, if it is determined that the terminal B approaches the terminal A in close proximity, the terminal A may transmit a BLE advertisement signal to the terminal B, and the terminal B may perform a discovery operation on the advertisement signal. Detailed embodiments of the second aspect of the present disclosure will be described later.

Hereinafter, embodiments will be described on the basis of using an advertisement signal of the BLE technology. However, the present disclosure is not limited to BLE, and communication between terminals may be performed through low-power short-range communication such as Ultrasound.

4 is a view for explaining the concept of an embodiment according to an aspect of the present disclosure.

Terminal 1 403 directly receives weather information from the server 401 that provides weather information. On the other hand, since terminals 2, 3, and 4 (405, 407, 409) are located in the same area as terminal 1 (403), they do not directly receive the weather information from the server 401, but have the weather information of the corresponding area. Weather information is provided from terminal 1 (403). To this end, the terminal 1 403 directly receiving the weather information from the server 401 corresponds to "specific information" preset to share the weather information with other terminals, so that the weather information is used as an advertisement signal of BLE. to the terminals of On the other hand, since the other terminals 405 , 407 and 409 correspond to "specific information" preset to receive the weather information from other terminals, in order to receive the weather information from the terminal 1 403, BLE A discovery operation for detecting an advertisement signal of Through the discovery operation, other terminals 405 , 407 , and 409 may receive the weather information. Meanwhile, the other terminals 405, 407, and 409 transmit the weather information as an advertisement signal again during the validity period of the weather information or within the number of valid hops of the weather information, so that other adjacent terminals can be shared with

For reference, the validity period of the weather information indicates a period during which the weather information is valid in a corresponding area. In addition, the effective number of hops indicates the number of times the weather information can be transmitted through terminals because the weather information is meaningful only within a certain area. When the server 401 advertises the weather information, the server 401 may advertise the valid period or the valid number of hops together in order to indicate a spatial and temporal limit in which the weather information can be shared. However, if the validity period information or the number of valid hops is not displayed in the advertisement including the weather information, the validity period or You can also set the number of valid hops.

Hereinafter, the validity period and/or the number of valid hops may be referred to as "sharing conditions" of specific information.

Hereinafter, with reference to FIG. 5 , a configuration of terminal devices for embodiments of the first aspect of the present disclosure and specific operations of entities for signal transmission and reception will be described. Meanwhile, although not shown in FIG. 5 and the configuration of the following terminal devices, the terminal device includes a control unit, so that overall operations of the terminal according to the present disclosure can be controlled. In addition, the terminal device includes a transceiver, so that it can transmit and receive information, signals, or messages with other entities.

5 is a diagram illustrating a case in which an information receiver of a terminal is provided with specific information according to an embodiment of the present disclosure.

Referring to FIG. 5 , an entity that provides preset specific information such as weather information and location information is referred to as an information provider 510 . The information provider 510 will be a server that provides the specific information. Meanwhile, entities that receive and consume the specific information in the terminal 1 500 and the terminal 2 520 are referred to as information receivers 501 and 521 . The information receiver may be a service entity, such as an application, widget, or the like, that typically provides a service to a user by using specific information. The number of the information providers 510 may be plural, and a plurality of the information receivers 501 and 521 may also be included in the terminal 1 500 and the terminal 2 520 . For example, there is an information provider and an information receiver for weather information, and an information receiver for location information exists. For convenience, in FIG. 5 , it is illustrated that one information receiver is included in each terminal.

In the embodiment of the first aspect of the present disclosure, there are three paths through which the information receiver 501 of the terminal 1 500 can receive specific information. First, it is a method of directly receiving information from the information provider 1 (510). Second, the method is provided through the update information transmitter/receiver 503 that receives specific information from the information provider 1 510 . Third, when the second terminal 520 has the specific information, it is a method of receiving the specific information from the other terminal 520 through the update information transceiver 503 .

Each component of FIG. 5 will be briefly described. Each of the terminal 1 ( 500 ) and the terminal 2 ( 520 ) includes one information receiver 1 ( 501 , 521 ) and update information transmitter and receiver ( 503 , 523 ).

The information receivers 501 and 521 are applications or service entities that are typically run in the terminal, and may receive weather information directly from the information provider 510 or through the update information transmitters and receivers 503 and 523 . .

The update information transmitter/receiver (503, 523) performs a function of a local proxy in the corresponding terminals (500, 520) during communication between the corresponding terminals (500, 520) and the information provider (510), the information provider 1 (510) It is possible to receive specific information from the information receiver and deliver it to the first information receivers 501 and 521 . In addition, the update information transceivers 503 and 523 communicate with other terminals 520 and 500 to provide specific information included in the corresponding terminals 500 and 520) to the other terminals 520 and 500, or Specific information included in the terminals 520 and 500 may be provided.

Meanwhile, in FIG. 5 , the update identifier manager 530 is illustrated by a dotted line. The update identifier manager 530 is configured between the original information and the update identifier that can be used to reduce the size of information transmitted and received between the update information transceivers 503 and 523 in the terminal 1 500 and the terminal 2 520 . The mapping relationship may be updated, and the updated mapping relationship may be synchronized with the update information transceivers 503 and 523 .

For example, according to the BLE communication regulations, when the size of the specific information is greater than or equal to a predetermined value (31 bytes), the specific information cannot be transmitted/received between terminals. In consideration of this, the update identifier manager 530 converts specific information (A) with a large amount of data into other data with a small amount of data (B), maps and manages the original data A and the converted data B, and manages them The update information may be provided to the transceivers 503 and 523 . Thereafter, data B mapped to data A by an arbitrary entity may be changed to data C for data security. When the mapping relationship of data is changed in this way, the update identifier manager 530 synchronizes the changed mapping relationship with the update information transceivers 503 and 523 in each terminal.

Hereinafter, embodiments of the present disclosure will be described based on the components of the present disclosure described above with reference to FIG. 5 .

There are four major embodiments according to the first aspect of the present disclosure.

The first embodiment is a scheme in which the information receiver receives specific information by using the update information transmitter and receiver, but does not use the update identifier manager.

The second embodiment is a method in which the information receiver uses the update identifier manager while receiving specific information using the update information transmitter and receiver.

The third embodiment is a method in which the information receiver receives specific information through the update information transmitter/receiver or the information provider, but does not use the update identifier manager.

The fourth embodiment is a method in which the information receiver receives specific information through the update information transmitter/receiver or the information provider, but does not use the update identifier manager together.

In the third and fourth embodiments, since the information receiver directly receives the specific information, or the update information sender receives the specific information, the information receiver and the update information sender are connected to one application or service entity. may be included.

On the basis of the above-described content, embodiments of the present disclosure will be described in detail below.

6 is a view for explaining an operation according to the first embodiment of the present disclosure.

In FIG. 6 , each of terminal 1 610 and terminal 2 620 includes two information receivers 613 , 615/623 , and 625 , and information provider 1 631 and information provider 2 633 exist. It was assumed that It is assumed that the information provider 1 631 provides location information and the information provider 2 635 provides weather information. However, hereinafter, a method of obtaining location information by the first information receiver 613 will be described for convenience, but the method described below is equally applied to a method by which the second information receiver 615 obtains weather information.

As described above, the first embodiment is a scheme in which the information receiver receives specific information using the update information transmitter/receiver, but does not use the update identifier manager.

For example, in a situation where the information receiver 613 of the terminal 1 610 needs to receive location information, the update information transceiver 611 operates as if it were the information provider 1 631 that provides location information. can To this end, the update information transceiver 611 may bind the destination domain of the message transmitted by the information receiver 1 613 of the terminal 1 610 to the IP address of the update information transceiver 611 .

For example, if the destination domain of the message transmitted by the information receiver 1 613 is "weather.co.kr" and the IP address corresponding to the domain is "123.456.789.123", the corresponding destination domain is set to that of the destination domain. It binds not to the IP address, but to "127.0.0.1", which is the IP address of the update information sender 611. This is based on the fact that, in the DNS operation procedure, the host, which is the DNS bind list, is searched first in the DNS queryer. way to do it As another method, a method in which the update information transceiver 611 operates as a proxy is also possible.

On the other hand, when the update information transceiver 611 receives an information request for the information provider 1 631 from the information receiver 1 613 , the update information transceiver 611 receives the location information from the information provider 1 631 . Without directly acquiring it, it attempts to acquire location information from another terminal by performing a BLE discovery operation. That is, since the information requested by the information receiver 1 613 is location information, which is specific information set to perform a discovery operation, the update information transceiver 611 performs a BLE discovery operation, and includes it in another terminal through the discovery operation The current location information is detected, the weather information is provided from another terminal, and the weather information is provided to the information receiving unit 1 ( 613 ).

That is, in FIG. 6 , the update information transceiver 611 of the terminal 1 610 performs a BLE discovery operation to detect the weather information advertised by the update information transceiver 621 of the terminal 2 620 , and the information receiver 1 forward to (613). Meanwhile, since the first embodiment of FIG. 6 does not use the update identifier manager 530, the location information shared by the information receiver 1 becomes latitude/longitude information or actual address information directly indicating the location of the corresponding area.

For reference, the location information included in the update information transceiver 621 of the terminal 2 620 may be directly received from the information provider 1 631 or may be received from another terminal.

7 is a view for explaining an operation according to a second embodiment of the present disclosure.

7, as in FIG. 6, each of the terminal 1 610 and the terminal 2 620 includes two information receivers 613, 615/623, and 625, and the information provider 1 631 and the information provider 2(633) is assumed to exist. It is assumed that the information provider 1 631 provides location information and the information provider 2 635 provides weather information. However, hereinafter, a method for the information receiver 2 (615) to obtain the weather information will be described for convenience, but the method described below is equally applied to the method for the information receiver 1 (613) to acquire the location information.

As described above, in the second embodiment, the information receiver uses the update identifier manager while receiving specific information using the update information transmitter and receiver. In FIG. 7 , the update identification management unit is indicated by an identification number 740 . Hereinafter, the second embodiment will be described in detail.

When transmitting/receiving specific information to share specific information between terminals, if the data amount of the specific information exceeds a certain value, transmission/reception of specific information between terminals may be restricted. For example, in BLE, an advertisement signal is limited to a data size of 31 bytes. Therefore, it is impossible to transmit/receive an advertisement signal exceeding 31 bytes. Accordingly, specific information exceeding a predetermined data amount may be converted or replaced with other information having a smaller data amount (hereinafter, collectively referred to as “conversion”), and transmission/reception between terminals may be performed using the converted information. For example, when the update information transceiver 621 of the terminal 2 620 includes weather information and the size of the weather information exceeds a predetermined value, the information mapped to the weather information is transmitted as an advertisement signal. do. According to a predefined mapping relationship, instead of data having a large data size, it is converted into information having a small data size to transmit an advertisement signal. Then, the update information transceiver 611 of the terminal 1 610 detects an advertisement signal including the converted information, and restores the converted information back to the original weather information. As an example, when the original information on the weather information is “light rain” and the data amount of the “light rain” exceeds a predetermined value, the information meaning “light rain” indicates that the data amount is less than or equal to a predetermined value. If it is promised as “0x0002”, information of “0x0002” is transmitted/received rather than “weak ratio” between terminals.

The mapping relationship between the original information and the transformed information is managed in the update identifier manager 740 . That is, the update information transceivers 611 and 621 acquire information on the mapping relationship between the original information and the converted information through message exchange with the update identifier manager 740 .

However, there are times when the mapping relationship between the original information and the transformed information needs to be changed for reasons such as security. Initially, the conversion information corresponding to “weak rain” was “0x0002”, but the update information transceiver 621 of the terminal 1 620 may change it to “0x0018” for security and management reasons, and thus the mapping relationship is changed If so, the changed mapping relationship should be communicated to the update identifier manager 740 . The update identifier manager 740 that has received this should notify all terminals of the change. However, in the present disclosure, the subject of the change of the mapping relationship is not limited to a specific terminal or server, and it can be assumed that any entity can attempt to change the mapping relationship for any reason.

In order to notify the terminals of the mapping relationship, the update identifier manager 740 keeps an application including the update identifier or an operating system (eg, Android, Tizen) including the application up to date, or A method of maintaining only the corresponding information of the terminal as the latest information may be used.

As described above, the third embodiment is a method in which the information receiver receives specific information through the update information transmitter/receiver or the information provider, but does not use the update identifier manager.

Specifically, in the third embodiment, the terminal may first attempt to obtain specific information from a terminal other than the server. For example, if it is assumed that the weather widget is an information receiver, and the weather widget intends to acquire the current location information of the terminal, the information receiver in the terminal uses the update information transmitter/receiver to access the location information that other terminals have already acquired and shared. You can try to receive

Conversely, the terminal may first attempt to acquire the specific information directly from the server, and if the attempt fails, the terminal may attempt to acquire the specific information from another terminal. That is, when the information receiver in the corresponding terminal requests specific information from the information provider a predetermined number of times, but does not receive a response from the information provider, the terminal may attempt to acquire specific information from another terminal using the update information transceiver. For reference, when the terminal requests information from the information provider a predetermined number of times, for example, it may be a case of requesting an HTTP GET message for the same URL more than a predetermined number of times.

That is, in the third embodiment, when the information receiver in the terminal first acquires specific information from another terminal through the update information transmission/reception unit, or the information receiver first requests specific information from the information provider, but fails, This is an embodiment in which the acquisition of specific information is attempted again through the

Meanwhile, in the fourth embodiment, the information receiver does not use the update identifier manager while receiving specific information through the update information transmitter/receiver or the information provider. However, since the description is a combination of the operation described in the third embodiment and the description of the update identifier management unit described in the second embodiment, a detailed description thereof will be omitted.

Meanwhile, as in the above-described embodiments, the method of transmitting and receiving specific information between terminals using a BLE advertisement signal enables the terminal to transmit and receive information desired by the terminal with low power. Accordingly, in a manner in which the terminal directly acquires specific information from an information provider, it may operate in a shorter period than a period in which information is received. For example, if the information receiver of the terminal directly receives weather information from the information provider every hour, the update information transmitter and receiver in the terminal may attempt to receive the weather information in a shorter period, for example, every 30 minutes.

Hereinafter, when specific information such as weather information or location information is shared, "shared condition information" that may indicate a temporal or regional range in which the specific information is effective will be described in detail.

As described above, for specific information corresponding to a preset condition, such as weather information or location information, a shared time range and regional range may be set according to sharing condition information for the specific information. The sharing condition information may be included in a BLE advertisement signal together with the specific information, or may be known through separate information transmission/reception.

First, the sharing condition information will be described with respect to the validity period information.

The terminal acquiring the specific information may transmit an advertisement signal including the specific information during the validity period for the specific information. However, if the validity period information for the acquired specific information cannot be obtained, the specific information may be shared with neighboring terminals for a time when the specific information is determined to be valid based on the acquisition time of the specific information. For example, if the information receiver directly obtains weather information from the information provider, and there is no valid period information for the weather information, set an effective period set as a default value (eg, 2 hours) for the weather information, and , the weather information can be shared with other terminals during the two hours. As another example, if the update information transceiver obtains weather information from the update information transceiver of another terminal and there is no valid period information, the validity period is set to a longer time (eg, 1 hour), and the 1 hour While the weather information can be shared with other terminals. Accordingly, the sharing condition information may include a creation date and time of the corresponding information. That is, even if a direct validity period is not set, if information on a generation time of the corresponding weather information is included, it is possible to implicitly limit how long the corresponding weather information will be valid information. However, the information on the generation time will generally be transmitted as an advertisement signal together with the weather information.

Next, "hop number information" among the sharing condition information will be described.

Since specific information such as weather information or location information is valid information only for a certain region, the number of hops through which the information is transmitted from one terminal to another is set, limiting the regional sharing range of the specific information have. However, since it is not limited only to the form of hop number information as a means of indicating the regional scope, the regional scope of the specific information may be limited by any method. As another method, in addition to a method of setting the number of hops of the specific information, a method of setting a terminal or an application from which the specific information is received may be used. To this end, a terminal or application that cannot receive specific information may be designated, or a terminal or application that can receive specific information may be designated. To this end, reception identifier information for designating or excluding a terminal or an application may be set as sharing condition information.

The sharing condition information for the specific information described in the above example may be set by an information provider that initially transmits the specific information or a terminal that receives it and shares it with other terminals.

As an example, the information provider may include sharing condition information such as generation time, valid period, and limited number of hops information in sea otter weather information while transmitting weather information for a specific area, and transmit the weather information including the shared condition information. The receiving terminal's update information transmitter/receiver will additionally include the current number of hops in the sharing condition information while advertising the weather information.

However, the sharing condition information may include only the initial advertisement time or the current hop number information, excluding the validity period information or the limited hop number information. The update information transceiver that has received the specific information may determine whether to reshare it by itself in consideration of the initial advertisement time or the current hop number information.

8 is a diagram for explaining an operation of a terminal according to an embodiment of the present disclosure.

The description of FIG. 8 shows an embodiment in which an information receiver directly receives specific information from an information provider if it first attempts to receive specific information from another terminal during the operation of the terminal according to the third embodiment and fails to receive the specific information. will be explained

In step 801, the terminal's update information transmitter/receiver first performs an advertisement signal detection operation for preset specific information such as weather information. This is to obtain specific information advertised by other terminals. In step 803, it is determined whether valid specific information is found through the advertisement signal detection operation.

If valid specific information is found, the valid specific information is transmitted to the information receiver in step 805 . Here, the valid specific information is information that is allowed to share the specific information according to the sharing conditions when the sharing conditions of the validity period and/or limited hop conditions are set in the specific information, and the sharing conditions of the valid period and/or the restricted hop conditions are If not set, it refers to information that can be recognized as currently valid in consideration of the initial advertisement time of the specific information or the current number of hops. However, hereinafter, for convenience of description, it is assumed that an effective period is set for specific information. Thereafter, the specific information found in step 807 is transmitted with an advertisement signal for a set valid period to share the specific information with other terminals during the valid period.

If valid specific information is not found in step 803, the information receiver directly acquires the specific information from the information provider in step 809. Thereafter, in step 811, it is determined whether the acquired specific information includes validity period information. If valid information is included, the process proceeds to step 813 and shares the specific information during the valid period. On the other hand, if the valid information is not included, proceeding to step 815 , the update information transmitter/receiver may set an appropriate validity period for the specific information obtained from the information provider, and may share the specific information during the valid period.

Hereinafter, another embodiment according to the first aspect according to the present disclosure will be described.

In the above-described embodiments, the terminal acquires weather information or location information from a server, transmits the obtained information as an advertisement signal to adjacent terminals, and shares the weather information or location information with other terminals. admit.

In the embodiments described below, a terminal transmits an advertisement signal including information necessary for controlling a specific function of another terminal, and the other terminal uses the information included in the received advertisement signal to receive a specific information included in the terminal. This is the embodiment used to control the function.

An example of the specific function may be a Wi-Fi function or a location identification function included in the terminal. For reference, the Wi-Fi function or the location identification function may be performed by a Wi-Fi module or a location identification module included in the corresponding terminal.

First, an example of controlling the Wi-Fi function by using information included in an advertisement signal received by the terminal is as follows.

Terminals whose Wi-Fi function is turned off may attempt to receive an advertisement signal continuously or at a predetermined period. A terminal connected to a Wi-Fi access point (AP) is a terminal whose Wi-Fi function is turned off In order to enable them to turn on the Wi-Fi function, the advertisement signal includes the identifier information of the Wi-Fi AP connected to the advertisement signal, and transmits the advertisement signal including the identifier information of the AP. have. For reference, the identifier information of the AP may be a Service Set Identifier (SSID), a Basic Service Set Identifier (BSSID), or the like. Meanwhile, terminals whose Wi-Fi function is turned off may receive the advertisement signal and access the Wi-Fi AP corresponding to the identifier information of the AP included in the advertisement signal.

As a specific example, when the terminal is connected to a Wi-Fi AP to which all terminals that do not require a Wi-Fi Protected Access (WPA) password or passphrase can be accessed, or when connecting to the Wi-Fi AP When the strength of the Wi-Fi signal is greater than or equal to a predetermined reference value and the connection to the Wi-Fi AP is maintained for a predetermined period of time or more, the terminal connected to the Wi-Fi AP displays an advertisement including identifier information of the corresponding Wi-Fi AP transmit a signal When another terminal whose Wi-Fi function is turned off receives an advertisement signal including the identifier information of the Wi-Fi AP, or receives the advertisement signal for a predetermined period of time and/or more than a predetermined number of times, the advertisement signal Upon receiving the , the terminal may turn on a Wi-Fi function that is turned off and access the corresponding Wi-Fi AP by using the Wi-Fi identifier information included in the advertisement signal.

However, the terminal may access the Wi-Fi AP without receiving an advertisement signal including the AP identifier information. For example, if there is a Wi-Fi AP to which the terminal has previously accessed, or there is a Wi-Fi AP provided by a carrier or operator of a communication service to which the terminal has subscribed, the terminal is the AP It is possible to access the Wi-FI AP by using a previous access history or stored Wi-FI AP identifier information without receiving an advertisement signal including identifier information.

Next, an example of controlling the location identification function by using the information included in the advertisement signal received by the terminal is as follows.

In general, a terminal includes a location identification function capable of estimating its location using GPS or based on Wi-Fi and/or cellular network information. However, when the GPS recognizes its own location when the terminal is located indoors, the GPS cannot be used in many cases. Therefore, it may be unnecessary for a terminal located indoors to attempt to use the GPS to identify its location.

In consideration of this point, a terminal using location information indoors may transmit an advertisement signal to prevent other terminals from checking location information using GPS. That is, the terminal using the location information indoors may transmit the advertisement signal including previously agreed information instructing not to use the GPS. Another terminal receives the promised information included in the advertisement signal, and the terminal does not use GPS to identify its location, but directly uses Wi-Fi and/or cellular network information to identify its own location. Location identification may be attempted. In this way, it is possible to prevent wastage of resources in which a terminal located indoors attempts to identify a location using GPS.

So far, embodiments according to the first aspect of the present disclosure have been described. Hereinafter, embodiments according to the second aspect of the present disclosure will be described.

The basic concept of the embodiment according to the second aspect of the present disclosure is to determine whether the first entity and the second entity are adjacent to each other according to various methods, and if adjacent to each other, the first entity is a BLE advertisement signal including a predetermined signal , and the second entity uses the information included in the advertisement signal.

First, a method for recognizing that one entity is close to another entity when two entities are close to each other will be described. Here, it is assumed that the two entities are the first terminal and the second terminal, respectively.

In the first method, it is possible to determine whether two terminals are adjacent to each other by checking the location of the terminal using the existing GPS and network information such as a cell identifier (Cell ID) or Wi-Fi. However, in the method of determining whether a neighbor is adjacent using network information, it is difficult to accurately determine the proximity situation within 1 m of the terminal due to an error in the location information.

In the second method, the first terminal temporarily transmits the BLE advertisement signal with a signal strength that can be received by the second terminal, which is the counterpart, and the second terminal receiving the advertisement signal allows the first terminal to be adjacent to the first terminal. location can be confirmed. That is, terminals can scan an advertisement signal transmitted by an adjacent terminal to determine whether another terminal is located adjacent to the terminal.

9 is a view for explaining a process of determining whether terminals are adjacent to each other using a BLE advertisement signal according to the second aspect of the present disclosure.

In step 911, for example, the second terminal 903 uses the above-described network information to determine the location information of the first terminal 901 and the second terminal 903, and based on this, the location where the two terminals are close to each other It is roughly understood that in However, in step 901, since network information is used, an error may occur as to whether it is located in a nearby location. Therefore, in order to more precisely determine whether the two terminals are in proximity, the proximity is determined again using the BLE advertisement signal. Specifically, in step 913, the second terminal 903 informs the server 905 that the first terminal 901 and the second terminal 903 are estimated to be adjacent, and in step 915, the server 905 sends the second terminal Instructs 903 to detect a BLE advertisement signal, and simultaneously or sequentially instructs transmission of a BLE advertisement signal to the first terminal 901 in step 916 . Accordingly, the first terminal 901 transmits a BLE advertisement signal, and in step 917, the second terminal 905 detects the BLE advertisement signal. The second terminal 905 that has detected the BLE advertisement signal can clearly determine that the first terminal 901 is in a distance adjacent to itself. Thereafter, in step 918 , the second terminal 905 notifies the server 905 that the advertisement signal has been detected. Since it has become clear that the two terminals are adjacent through the transmission and reception of the advertisement signal, the first terminal 901 does not need to transmit the advertisement signal any more. Accordingly, the server 905 instructs the first terminal 901 to stop transmitting the advertisement signal. After that, since it became clear that both are adjacent, both terminals can perform a necessary operation thereafter. For example, using a technology such as Wi-Fi Direct that can exhibit good performance only when two terminals are very close to each other, both terminals can transmit and receive necessary information.

As a modified example of the embodiment described with reference to FIG. 9 , steps 911 and 913 may be omitted. That is, in step 911, the second terminal 903 uses the network information to determine the positions of the first terminal 901 and the second terminal 903, and after approximating that both terminals are adjacent to each other, in step 913 Server 905 was reported. However, the above steps may be omitted. In this case, the server 905 instructs the second terminal 903 to detect the BLE advertisement signal in step 915 without reporting the second terminal 903, and transmits the BLE advertisement signal to the first terminal 901 in step 916. will instruct

The above-described embodiment of FIG. 9 may be applied to a case in which a parent recognizes the location of a child. That is, when the embodiment of FIG. 9 is applied to the terminal owned by the parent and the terminal owned by the child, the parent can determine whether the terminal owned by the child is adjacent to the terminal at a certain period.

In the present disclosure, signal transmission and reception between devices of the above-described BLE advertisement signal is applied to a door lock system.

10 is a diagram illustrating a door lock system using a BLE advertisement signal according to an embodiment according to the second aspect of the present disclosure.

The door lock system of FIG. 10 includes a terminal 1003 and a server 1005 including a door lock 1001 and an electronic key function.

First, the door lock 1001 detects that the terminal 1003 is adjacent within a predetermined distance by the various methods described above (1). At this time, whether the adjacent state can be detected using a separate sensor provided in the door lock, for example, an infrared sensor or an ultrasonic sensor.

The door lock 1001 transmits a message informing the server 1013 that the terminal 1003 is in an adjacent state (2). The server 1005 transmits a message instructing transmission of an advertisement signal to the terminal 1003 (3). Accordingly, the terminal 1003 transmits an advertisement signal including electronic key information, and the door lock 1001 detects the advertisement signal advertised by the terminal 1001, and a terminal including an electronic key to verify the integrity of the electronic key. The electronic key is verified by performing a connection with (1003), and when the electronic key is verified, the door lock is unlocked (4). However, only by receiving an advertisement signal including the electronic key without verification of the electronic key, a method of releasing the door lock is also possible.

When the proximity detection function and advertisement signal transmission/reception method are introduced into the door lock in this way, even when the user cannot operate the terminal including the electronic key because the user is holding an object in both hands, the power consumption of the terminal is minimized and the user's additional operation is reduced. The user convenience is greatly increased as the door lock can be unlocked without the need for a door lock.

11 is a view for explaining an embodiment of a door lock system that can be applied to a door lock system using a BLE advertisement signal according to an embodiment according to the second aspect of the present disclosure when visiting a home to visit a courier service delivery person.

When the terminal 1103 possessed by the delivery man notifies the delivery company server 1107 of the visit in advance, the delivery company server 1125 instructs the terminal 1103 of the delivery delivery person to transmit an advertisement signal (1). When the delivery person visits the house and the terminal 1103 of the delivery delivery person transmits an advertisement signal, the door lock 1101 detects the advertisement signal and informs the door lock server 1105 that the advertisement signal has been detected (2) . The door lock server 1105 requests the delivery company server 1125 to confirm the advertisement signal (3), and the delivery company server 1125 sends a message confirming that the advertisement signal is an advertisement signal of the courier delivery service to the door lock server ( 1105) (4). The door lock server 1105, which has confirmed that the advertisement signal is an advertisement signal of the courier delivery man, provides a notification of the courier delivery man visit to the terminal 1109 of a user who has the right to enter the door, such as the owner of the house (5).

12 is a diagram illustrating a file sharing system for transmitting and receiving files between devices using a BLE advertisement signal according to an embodiment according to the second aspect of the present disclosure.

In FIG. 12 , it is assumed that terminal 1 1203 , terminal 2 1205 , terminal 3 1207 , and terminal 4 1209 are preset as a group capable of sharing a photo file. However, terminal 5 1211 did not belong to the sharing group.

Terminal 1 1203 uploads the photo file it owns to the server 1201 ( 1221 ), and the server 1201 transmits URL information of a place where the photo file is stored to terminal 1 1203 ( 1223). On the other hand, the server 1201 transmits the security key for downloading the photo file to terminal 1 ( 1203 ), terminal 2 ( 1205 ), terminal 3 ( 1207 ), and terminal 4 ( 1209 ), which are the file sharing groups ( 1225 ). . However, the server 1201 did not transmit the security key to the terminal 5 ( 1211 ) ( 1226 ). Terminal 1 (1203) transmits a BLE advertisement signal including URL information in which the photo file is stored (1227). In this case, the advertisement signal may include group information or terminal identifier information for identifying a specific sharing group.

Terminal 2 ( 1205 ), terminal 3 ( 1207 ), and terminal 4 ( 1209 ) may receive the photo file and download the file stored in the URL of the server 1201 using the received security key. In addition, the terminals receiving the URL information may transmit an advertisement signal including the URL information and identifier information of the receiving group or the receiving terminal again. In FIG. 12 , terminal 2 1205 and terminal 3 1207 are shown to advertise URL information.

13 is a view for explaining an embodiment of controlling a corresponding peripheral device using an advertisement signal of a peripheral device through an app including a camera function in a user terminal according to an embodiment according to the second aspect of the present disclosure.

First, the user drives a specific app (APP) included in the user terminal 1301 (1). It is assumed that the specific app is an app set to control a peripheral device. The specific app includes a camera function, and an image of a peripheral device may be displayed on the screen of the user terminal through the camera function. If the user terminal 1301 wants to control the displayed peripheral device through the camera function, the peripheral device near the user terminal 1301 requests the server to transmit a visual advertisement signal (2). The specific content of the visual advertisement signal will be described later.

The server 1309 checks the location of the user terminal 1301 according to the request (3-1), and checks the peripheral devices located within a predetermined radius from the user terminal 1301 (3-2). Also, the server 1309 checks a peripheral device available to the user terminal 1301 among the peripheral devices (3-3). For reference, the server 1309 may identify peripheral devices within a predetermined radius from the user terminal 1301 based on the absolute or relative position method. An example of the absolute location method is a method using network information such as GPS, Wi-Fi BSSID, or cell ID of a cellular base station, or a method using a preset geographic radius called a geo-fence, and the relative method includes , it may be a method of setting a reference radius as a distance within a range in which a BLE advertisement signal of a BLE beacon is detected.

Meanwhile, in FIG. 13 , it is assumed that the peripheral devices available to the user terminal 1301 include a lighting lamp 1303 , an air conditioner 1305 , and a smart TV 1307 . The server 1309 transmits an instruction message to the identified peripheral devices to transmit an advertisement signal (4). Thereafter, the peripheral devices that have received the corresponding instruction message transmit a visual advertisement signal (5). The visual advertisement signal may be, for example, a signal that can be visually recognized, such as a blinking light signal or QR code information, and the visual advertisement signal includes URL or IP address information in which information for controlling a corresponding peripheral device is stored. may be encoded and included.

The user terminal 1301 may recognize the visual advertisement signal through the app, decode the visual advertisement signal to obtain URL information or IP address information, and information for controlling a corresponding peripheral device from the URL or IP address can be obtained. The information for the control may be, for example, menu information for controlling a channel or volume of a TV. The user terminal 1301 acquires information for such control and displays it on the image of the corresponding peripheral device in the app of the user terminal 1301 (6). Thereafter, when the user selects a specific control menu based on the information for controlling the peripheral device, the user terminal 1301 transmits a signal for controlling the corresponding peripheral device to the server 1309 (7). The server 1309 may control the corresponding peripheral devices through the network according to the control signal transmitted by the user terminal (8).

14 is a diagram illustrating an example in which a user terminal displays control information for controlling a peripheral device according to the embodiment described with reference to FIG. 13 described above.

That is, in FIG. 14 , the peripheral devices displayed on the screen of the user terminal 1400 by the camera function of the user terminal 1400 are the lighting lamp 1401, the smart TV 1405, and the air conditioner 1409, and accordingly the user terminal ( The 1400 requests the server 1309 so that the peripheral device transmits an advertisement signal, and the server 1309 instructs the peripheral devices available to the user terminal 1400 among the corresponding peripheral devices to transmit the advertisement signal. Accordingly, the lighting lamp 1401 and the smart TV 1405 transmit a visual advertisement signal in the form of the blinking lights 1402 and 1404, and the air conditioner 1409 transmits a visual advertisement signal in the form of a QR code 1410. was shown The visual advertisement signal may include URL information or IP address information encoded using a blinking pattern of light or a QR code, and the user terminal 1400 that receives and decodes the visual advertisement signal to obtain the URL information or IP address. ) obtains control information for each peripheral device from the URL information or IP address. In FIG. 14 , control information is indicated by reference numerals 1403 and 1405 . That is, in the case of the lighting lamp 1401 , the control information 1403 for controlling the corresponding lighting lamp includes an example including on/off, brightness adjustment, and color change menu of RGB bulbs, which are types of lighting lamps. In the case of the smart TV 1405, an example in which on/off of the corresponding smart TV, channel change, volume control menu, etc. are included as control information 1407 is illustrated. The control information on the screen of the user terminal 1400 may display the corresponding peripheral device on a portion where the visual advertisement signal is generated, so that the user who has viewed the control information can intuitively control the corresponding peripheral device.

On the other hand, as a modified embodiment of the embodiment of FIGS. 13 and 14, when detailed information related to the content of a TV program is required as in the case of the smart TV 1405, the control information is transmitted using the visual advertisement signal, It is also possible to additionally transmit information on the corresponding content through a signal other than a visual advertisement signal, for example, a sound signal or a BLE advertisement signal.

15 is a view for explaining a process of differently performing a message transmission/reception method according to whether a message is in a neighboring state in a messaging service according to another embodiment of the present disclosure;

In general, in the case of a messaging service such as a messenger, a transmitting terminal and a receiving terminal do not directly transmit/receive a message, but transmit/receive a message via a server. Therefore, large-capacity files cannot be transmitted/received through messenger. The embodiment of FIG. 15 is a content for performing a messaging service by directly connecting the transmitting and receiving terminals without going through a server when the transmitting and receiving terminals are adjacent to each other according to whether an advertisement signal is detected.

In step 1501, the sending terminal attempts to transmit a message, and in step 1503, it is checked whether the size of the message to be transmitted is a size allowed by the messaging server. If the size of the message is larger than the allowed size, in step 1505, the transmitting terminal transmits the message through the messaging server according to a typical messaging method. If the size of the message is larger than the allowed size, in step 1507, the messaging client of the transmitting terminal transmits information about the receiving terminal (ie, identifier information of the receiving terminal) to the server. In step 1509, the messaging server instructs the transmitting terminal/receiving terminal to transmit/detect the advertisement signal. That is, the messaging server instructs either the transmitting terminal or the receiving terminal to transmit an advertisement signal, and instructs the other one to detect the advertisement signal.

If the terminal instructed to detect the advertisement signal in step 1511 detects the advertisement signal, in step 1513 the messaging server transmits information for mutual connection to the messaging clients of the transmitting terminal and the receiving terminal. In step 1515, the messaging client of the sending terminal and the messaging client of the receiving terminal perform message transmission and reception without going through the messaging server.

16 is a diagram illustrating an example in which a user terminal displays control information for controlling a peripheral device according to another embodiment of the present disclosure.

In the embodiment of FIG. 16 , in order to minimize the case in which terminals transmit unnecessary advertisement signals, the server requests transmission of advertisement signals from terminals located within a predetermined area. This is an embodiment in which terminals transmitting the advertisement signal and terminals detecting the advertisement signal are set as one terminal group. The specific operation is as follows.

(1) The user terminal A 1601 requests the server 1611 to set a group of user terminals.

(2) The server 1611 instructs the terminals existing in the predetermined area 1621 to transmit an advertisement signal. In FIG. 16 , terminals existing in the predetermined area 1621 are terminal B 1603 and terminal C 1605 . It should be noted that the transmission of the advertisement signal may not be instructed to the terminal D 1607 existing outside the predetermined area 1621 . This is shown as a dotted line.

After the server 1611 receives the group setting request from the terminal A 1601, when it requests transmission of an advertisement signal to all nearby terminals, the terminal D 1607 far from the terminal A 1601 sends the advertisement signal. If so, the possibility that the terminal A 1601 cannot receive the advertisement signal transmitted by the terminal D 1607 is very high. Therefore, in this case, the terminal D 1607 is a result of transmitting an unnecessary advertisement signal.

In the embodiment of FIG. 16 , in order to prevent unnecessary transmission of an advertisement signal, the advertisement signal may be transmitted only to terminals located in a predetermined area. In this case, in the method of setting the predetermined area, the distance between terminals and the transmission power of the advertisement signal may be considered.

In addition, after transmission and reception of an advertisement signal, the importance of the type of data to be transmitted and received by terminals configured as a group may be considered. For example, if data transmission/reception is absolutely necessary between the terminal A 1601 and the terminal D 1607, the terminal A 1601 transmits the identifier of the terminal D 1607 to the server 1611 when the grouping request is made, and the server In response to the request of the terminal A 1601 , the terminal D 1607 may be outside the predetermined area 1621 , but the terminal D 1607 may also request transmission of an advertisement signal. However, in this case, the server 1611 may request the terminal D 1607 to increase the transmission power of the advertisement signal.

(3) Also, the server 1611 instructs the terminal A 1601 to detect advertisement signals transmitted by other terminals.

(4) The terminal A 1601 detects the advertisement signal transmitted by the terminal B 1603 and the terminal C 1605, and the detection result of the advertisement signal transmitted by the mall terminal B 1603 and the terminal C 1605 The server 1611 is notified.

(5) The server 1611 receives the detection result, and sets the terminal A 1601, the terminal B 1603, and the terminal C 1605 as one group.

According to the embodiments of the present disclosure described so far, when a plurality of terminals are expected to acquire the same information due to similar or identical conditions, a plurality of terminals are concentrated, such as in a concert hall, so that the network connection is unstable, or information is provided Even in a situation where it is difficult to provide information due to a large number of users in the server at once, a small number of terminals can acquire necessary information and share it with terminals that satisfy a predetermined condition, so that network resources can be efficiently used. In addition, since the user can receive necessary information through communication between terminals without using network communication with a server for data reception, necessary information can be obtained without charging for information reception. In addition, since information is transmitted and received using low-power short-range communication, power consumption of the terminal can be minimized.

In addition, by temporarily operating at least one terminal among a plurality of terminals as an advertisement device and operating the remaining terminals as detection devices, when acquiring location information of a terminal through a network using Wi-Fi and a cell identifier, or by GPS It is possible to more accurately determine whether the terminals are adjacent to each other than when the location information is obtained.
