DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise. In addition, the terms “… unit”, “… unit”, “module”, etc. described in the specification mean a unit that processes at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software. have.

Hereinafter, a concept of determining a real-time group according to an embodiment of the present invention will be described with reference to the drawings.

1 is a diagram illustrating a beacon message transmission and reception concept through beacon information relay according to an embodiment of the present invention.

Referring to FIG. 1, when a beacon message is transmitted from a Bluetooth low energy (BLE) -based fixed beacon transmitter 100, terminals 102, 103, 104, 105, and 106 located in a reception range 101 are provided. 107, 108, hereinafter referred to as "102-108" will receive a beacon message. At this time, the terminals 102 to 108 are provided with a beacon receiver that can receive a beacon message. Here, the recent beacon service is a Bluetooth-based transmitter is used a lot, but can be provided through a similar configuration through other short-range wireless communication technology such as WiFi.

The beacon transmitter 100 periodically transmits a beacon message, and when the terminals 102 to 108 enter the reception range 101 of the beacon message, the terminals 102 to 108 automatically receive the beacons.

Terminals 102 to 108 are equipped with a Bluetooth or WiFi transceiver module is possible to receive beacons. In addition, in some smartphones, Bluetooth-based beacon reception is set to a default mode (Default Mode) so that the beacon can be received even if the user does not recognize the beacon service.

Meanwhile, the received beacon message includes a universally unique identifier (UUID) of the beacon, so that the terminals 102 to 108 recognize the beacon through the UUID information, and then request detailed information such as an installation location of the beacon to a separate server. .

Recently, the updated mobile OS for smartphones, including the beacon message receiving function, includes a calling function so that smart phones can receive and send beacon messages as well. This allows for dynamic triggering of services.

Since the conventional beacon transmitter 100 has a low power characteristic, the computing power is relatively low, so that the beacon transmitter 100 has a minimum function such as transmitting only a static beacon message. It couldn't do anything other than receive a beacon message.

However, as smart phones with excellent computing power can be utilized as relays for beacons, various modifications to beacon messages can be made, and dynamic messages can be generated to create new services.

For example, as shown in FIG. 1, a method of generating grouping information in real time through transmission and reception of a security-enhanced relay beacon message between terminals 102 to 108 that have received a beacon message of the beacon transmitter 100 is provided. Can be suggested.

Each of the terminals 102 to 108 that have received the beacon message sent by the beacon transmitter 100 transmits a relay beacon message. The relay beacon message should be generated as temporary information that can uniquely identify the terminals 102 to 108 only in the reception range 101 of the fixed beacon message.

This information can be implemented as temporary token information generated through the server. Including static information that can identify the terminal in the beacon information of the terminals 102 to 108 may be a problem in protecting personal information. Whether or not the beacons can be relayed in the terminals 102 to 108 may be enabled by setting a state in which a beacon can be transmitted and received together with the service use agreement.

Through the transmission and reception of beacons relayed between the terminals 102 to 108, the approximate distance between the terminals 102 to 108 may be known, and the probability that the terminals 102 to 108 belong to the same group is calculated using the beacons.

If the grouping information is extracted in real time by obtaining probability values for a certain period in time, it is possible to identify and provide whether or not it is a party through the same meeting. In order to calculate the grouping information, it is possible to find an optimal period through experiments. These periods can be set differently depending on time of day or intensity.

The time of forming the same group will be different for restaurants and coffee shops, and different times for commute and lunch. The optimal period information can be stored in the server and used in calculating the probability.

The longer the period, the higher the accuracy can be in terms of probability, but the real time may be degraded, and the probability may be reduced at some point when the group is released.

Referring to the example of FIG. 1, according to the grouping information calculated through the relay beacon message between the terminals 102 to 108, it is highly likely that the terminals 102, 103, and 104 form one group, and the terminals 105 and 106. ) Is likely to form one group.

2 is a diagram illustrating a beacon receiving timing of the terminal within the beacon receiving range according to an embodiment of the present invention.

Referring to FIG. 2, assuming that the terminals a to n are within the reception range 101 of the beacon transmitter 100, each terminal a to n has entered various time zones within the reception range 101. Able to know. In addition, the terminals a to n are expected to be out of range in several time zones rather than the same time zone.

Meanwhile, the probability that each terminal a to n belong to the same group is calculated only when each terminal a to n is within the reception range 101 and is calculated only for a predetermined period. For example, since only terminals a, b, and c are located within the reception range 101 during a unit period of t = T 4 to t = T 5 in FIG. 2, the terminals a, b, and terminal b, c), the probability that the terminals (a, c) or the terminals (a, b, c) belong to the same group is obtained.

The probability information obtained between the terminals during the unit period can be observed for a certain period to increase the accuracy.

[Equation 1]

Figure 112015081962095-pat00007

[Equation 1] is a formula for the probability that the terminal (a, b) belongs to the group G ab when the terminal (b) receives the relay beacon message transmitted from the terminal (a) in the period T 1 . here,

Figure 112015081962095-pat00008
Is the distance between the terminal (a) and the terminal (b) in the period of t = T 1 , which is inversely proportional to the beacon received RSSI (Received Signal Strength Indication) value between the two terminals (a, b), the inverse RSSI After taking, it can be obtained by calibrating according to the reception sensitivity according to the characteristics of the terminals (a, b). In addition,
Figure 112015081962095-pat00009
Is the maximum distance between the terminals (a, b) in the period of t = T 1 . In addition,
Figure 112015081962095-pat00010
The value is an adjustment value that is periodically updated through experiments in the server because sensitivity and transmit / receive strength are different according to the type of terminal.

Probabilities of being in the same group are calculated for a certain period by using the probability values for the unit periods. These probabilities can be obtained by product of each probability since each probability is independent during each period.

[Formula 2]

Figure 112015081962095-pat00011

[Equation 2] is an expression representing the probability that the terminal (a) and the terminal (b) belong to the same group when [Equation 1] is observed for a certain period.

When observing for a certain period T 1 for T n , if the value of [Equation 1] is produced with respect to time, the probability P (G ab ) for the group G ab during the corresponding period can be obtained.

In case of group with very small probability in the process of [Equation 2], if you take the product with respect to time, it has a very small value and can exceed the calculation range. .

[Equation 3]

Figure 112015081962095-pat00012

[Equation 3] is a logarithmic scale representation of the equation for the probability that the terminals (a, b) are the same group for a certain period (T1 ~ Tn).

The calculated value in [Equation 2] may be so small in some cases that it may be beyond the general computing range. The longer the probability calculation time, the greater the difference in probability values between groups and non-groups. Since the absolute value of the same group between the actual terminals is not important, it is important to compare the magnitudes of the probability values, and thus there is no problem in calculating the probability values on the log scale as shown in [Equation 3].

Table 1 below is an example of a probability data table belonging to the same group between the beacon receiving terminals (a to n) calculated through the above [Equation 3].

TABLE 1

Figure 112015081962095-pat00013

[Table 1] shows the value of calculating the probability of belonging to the same group between the pair of each terminal obtained through [Equation 1], [Equation 2], [Equation 3] is P (G ab ) = 0.64, P ( G ac ) = 0.45, P (G ad ) = 0.021, P (G ae ) = 0.0003, P (G ba ) = 9.478, P (G bc ) = 0.91, P (G bd ) = 0.0015, P (G be ) = 0.0007, P (G ca ) = 0.781, P (G cb ) = 0.89, P (G cd ) = 0.0124, P (G ce ) = 0.0021.

As such, the obtained probability values are stored in a server by grouping pairs having a predetermined probability or more through a predetermined threshold.

In the example of [Table 1], there are two parts shown in black, which are a group consisting of terminals (a, b, c) and a group consisting of terminals (d, e), and have a user having terminals (a, b, c). User with the terminal (d, e) can be determined to be the same party at the place.

Such a probability value may cause an error due to a change in reception intensity according to a terminal characteristic and a radio wave reception environment. In such a case, the group may be classified by rounding up or down, or by applying a basic weighting algorithm in consideration of the error in the probability value. For example, the probability of receiving a beacon transmitted from the terminal a from the terminal b and receiving a beacon transmitted from the terminal b from the terminal a has a probability greater than one threshold. If one does not exceed, all of them may be put in the same group, all of them may not be put in a group, or they may have a large probability value, or the weight may be obtained by applying a weight to a terminal having a small transmission / reception error of a beacon. In addition, if the error is large, it is possible to reduce the error by increasing the observation period.

Hereinafter, a real-time group information providing service system according to an embodiment of the present invention will be described with reference to the drawings.

It generates and stores in the group information record DB (420) to manage.

The group information providing unit 440 extracts group information and terminal information related to the terminal 200 stored in the group information record DB 420 and provides the terminal 200 to the terminal 200 according to a request of the terminal 200. .

Meanwhile, in the exemplary embodiment of the present invention, the terminal service system 300 and the application service system 400 are separated and described as separate systems. However, the terminal service system 300 and the application service system ( 400 may be integrally included in one system.

Hereinafter, a method of providing real-time group information providing service according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

4 is a flowchart of a method for providing real-time group information providing service according to an exemplary embodiment of the present invention.

In FIG. 4, only two terminals (terminal 1 and terminal 2) are considered for convenience of description, and the description may also be applied when three or more terminals are located in the beacon receiving range 101.

Referring to FIG. 4, first, two terminals, that is, terminal 1 and terminal 2, receive a beacon transmitted from the beacon transmitter 100 when entering the beacon receiving range 101 of the fixed beacon transmitter 100 ( S100, S101).

Accordingly, each terminal (terminal 1, terminal 2) parses the received fixed beacons to request and receive detailed information to the terminal service system 300 (S110, S111).

Next, after confirming whether the corresponding beacon is a beacon capable of real-time group information providing service through detailed information received (S120, S121), each terminal (terminal 1, terminal 2) is a beacon that provides real-time group information providing service. If it is confirmed that the authentication token for distinguishing each terminal (terminal 1, terminal 2) to the terminal service system 300 to receive and receive (S130, S131).

Thereafter, each terminal (terminal 1, terminal 2) generates a secure relay beacon using the received authentication token (S140, S141) and transmits a relay beacon to different terminals (terminal 1, terminal 2) ( S150). Of course, since the relay beacons transmitted by each terminal (terminal 1, terminal 2) are transmitted in a broadcasting manner, it does not specify a terminal to receive the relay beacon, but only two terminals (terminal 1, terminal 2) are assumed here. It is expressed in this way because the same result as the relay beacon is transmitted to different terminals by the casting method.

Next, each terminal (terminal 1, terminal 2) receives the relay beacon transmitted from the different terminals and transmits the information of the received relay beacon to the terminal service system 300 and requests the processing for the relay beacon (S160, S161).

Therefore, the terminal service system 300 can calculate the probability of belonging to the same group by using the information of the relay beacons transmitted from each terminal (terminal 1, terminal 2) (S170). At this time, the terminal service system 300 may authenticate that each terminal (terminal 1, terminal 2) is a valid terminal through the information of the relay beacon.

Thereafter, the terminal service system 300 transmits probability information belonging to the same group calculated in the step S160 to the application service system 400 (S180).

Next, the application service system 400 generates real-time grouping information using the probability information delivered from the terminal service system 300 and stores the grouping information in the group information record DB 420 (S190 and S200). The grouping information includes information of terminals belonging to the same group, group information, place information, time information, etc., formed by the corresponding terminal.

Then, when the real-time grouping information is requested for the application service from the terminal (terminal 1, terminal 2) (S210, S211), the application service system 400 using the information stored in the group information record DB (420) Grouping information for each terminal 1 and terminal 2 is extracted (S220), and grouping information is provided to each terminal (terminal 1, terminal 2) (S230, S231).

As such, the real-time grouping information provided from the application service system 400 to each terminal (terminal 1 and terminal 2) may be variously used in an application application of the terminal (terminal 1 and terminal 2).

For example, using the group information record and the user information of the terminal (terminal 1, terminal 2) together to provide information on the day of the meeting with friends or information about the unknown person sitting next to me. It may be offered in the future.

It is also possible to provide the highest probability of information about who ate at the same table a month ago at the university cafeteria.

In the existing location information service using a local area network, it is possible to determine whether the local area network is within an accessible area. However, the group information providing service method according to an embodiment of the present invention has a high probability of being the same party. Information can be provided.

5 is a diagram illustrating an application service using real-time group information provided according to a real-time group information providing service method according to an embodiment of the present invention.

Referring to Figure 5, when the fixed beacon transmitter 100 is built three people waiting for the order to enter the restaurant (S300) using the three or the user information to one of them 2 + 1 event information coupon If you provide (S310) the purchase rate of the product will be much higher.

In addition, in the case of two parties or lovers (S400) it is possible to provide a couple event coupons (S410), it is possible to utilize for family marketing (S500, S510).

At this time, the user information can be solved in large part even if only the grouping information and the age information are required without all of the personal information.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.
