Hereinafter, a network environment including the heterogeneous device interworking apparatus 100 and the heterogeneous device interworking apparatus 100 according to the present invention will be described with reference to FIG.

Referring to FIG. 1, the present invention is based on a system including a heterogeneous device interworking apparatus 100 and a plurality of devices connected to the wireless network.

The plurality of devices may be electronic devices, each of which may perform its own functions, including a smart phone 501, a smart watch 503, a portable computer 505, a desktop computer 507, a smart television, have.

The plurality of devices can be interworked with each other through the wireless network as well as with the heterogeneous device interworking apparatus 100 to be described later. In this case, interworking refers to transmission of various types of data such as moving picture, image, audio, and text on the premise that data can be transmitted and received according to a communication protocol. Of course, And the like.

Meanwhile, the heterogeneous device interworking apparatus 100 according to the present invention recognizes a plurality of peripheral devices and calculates an interworking fitness between any device, that is, the target device 300 and the peripheral devices 501 to 507 other than the target device 300 As a main function.

Specifically, the heterogeneous device interworking apparatus 100 determines three factors in determining the interlocking fitness, including device sociality, device preference, and device reliability. Each element will be described in detail with reference to FIG. 2 to FIG.

Meanwhile, the heterogeneous device interworking apparatus 100 according to the present invention may be a single device, for example, a server having a central control unit (CPU) and a memory.

A device recognizing part for recognizing the peripheral devices connectable via the network, ii) a device recognizing part for interworking with any of the recognized devices and the recognized peripheral devices, when the detailed configuration of the heterogeneous device interworking device 100 is divided functionally, And iii) a controller for controlling the device recognition unit and the operation unit.

The device recognizing unit recognizes devices existing around the heterogeneous device interworking device 100, more precisely, devices capable of being connected through the network. At this time, the device recognizing unit does not merely recognize the possibility of connection with peripheral devices, but may collect information necessary for calculating future inter-connection fitness from each device. For example, the device recognition unit may acquire information necessary for future interworking fitness calculations such as the intensity of a signal received from a plurality of devices, a history in which devices transmit and receive data with other devices, a type of data transmitted / Can be collected.

Meanwhile, the arithmetic unit calculates interworking fitness between arbitrary devices and other devices, and ultimately implements interworking between devices with the highest interworking suitability. In this case, the interworking interrelation is classified into three types: Sociality, device preference, device reliability, and the like. The calculated result values are used to determine whether any device, that is, the target device 300, should interwork with another device in the future.

Meanwhile, in the present invention, a range for calculating an interlocking fitness is described as a process for implementing optimal interworking between arbitrary devices and other devices, and the actual interlocking process between other devices is described in the scope of the present invention The detailed description will be omitted.

Finally, the heterogeneous device interworking apparatus 100 may further include a control unit, which may include at least one computing unit, which may be a general purpose central processing unit (CPU) An implemented programmable device device (CPLD, FPGA), an application specific integrated circuit (ASIC), or a microcontroller chip.

Hereinafter, the process of calculating the interlocking fitness and each type of interlocking fitness will be described with reference to FIG. 2 to FIG.

2 is a flowchart illustrating a method of interworking with a heterogeneous device according to the present invention. Referring to this, a heterogeneous device interaction method includes a device sociality operation step, a device preference operation step, and a device reliability operation step. The heterogeneous device interworking method may include any one of the above steps, but it is most preferable that the above three steps are sequentially performed.

Hereinafter, each operation step will be described.

The device sociality computing step is a step in which an arbitrary device measures an interworking environment with other devices. The device sociality means one value of interlocking fitness. The value can be calculated based on the distance, signal strength or distance between any device and other devices, and signal strength.

FIG. 3 is shown to help conceptual understanding of device sociality. In this case, one target device 300 may be connected to a number of other devices 501-507 via a network. In this case, the signal strength between the target device 300 and other devices may be different from each other . 3, the target device 300 may be networked with other smartphones 501, a smart watch 503, a portable computer 505, a desktop computer 507, and the like , -32dBm, -25dBm, -86dBm, -70dBm, respectively, between the respective devices and the target device 300, respectively. In this case, the signal intensity values may be defined as the device socialities that the target device 300 has with other devices, respectively. Of course, the signal strength is only one of the values that can be defined as the device sociality, and according to the intention of the designer, the device sociality is the distance or distance between the target device 300 and the peripheral device, But may be defined as separate values included as parameters.

Meanwhile, the device sociality calculation step includes a process of selecting only a peripheral device having a value greater than a specific threshold value after grasping the device sociality value between the target device 300 and the peripheral device. In this case, the threshold value is a value that distinguishes how well the target device 300 interlocks with peripheral devices, which is generally a sum of all the device sociality values between the target device 300 and the peripheral devices And the average value of the posterior value is obtained.

The threshold value can be calculated, for example, by the following equation (1).

At this time, Received Signal Strength Indication (RSSI) is a mathematical conversion of a certain relationship with the signal intensity along the distance. That is, when the RSSI value of the device is relatively high, the device can be regarded as having good transmission speed and quality in relation with other connected devices.

In Equation 1, n represents the total number of all devices existing in the vicinity of the target device 300, and more precisely, the number of devices connected to the target device 300 through the wireless network.

To sum up, based on the above equation 1 again this end, the threshold (θ _DS) may be defined as a value divided by the number of all the devices connected to it after the sum of the RSSI values between target device 300 and the peripheral device. In Equation 1, 0.1 is a coefficient for adjusting the value of the threshold value between -1 and 1, i.e., for scaling.

The device sociality computing step is a step of acquiring a device sociality value indicating the degree of interworking between the target device 300 and the peripheral device, and further comparing the device sociality value with a threshold value, And a process of selecting a peripheral device corresponding to the sociality value.

The second step of the heterogeneous device interaction method is to calculate the device preference.

FIG. 4 is a conceptual illustration of device preferences for easy understanding. The device preference means a value that allows the target device 300 to know how much information is shared with the peripheral devices 501 and 503. That is, the device preference is calculated on the basis of the degree to which an arbitrary device shares information with another device.

For example, referring to FIG. 4, the target device 300 may share various kinds of content with other smartphones 501 or other smart watches 503, May be calculated on the basis of the number of times that the target device 300 shares the content with the other smartphone or the amount of data that the target device 300 has shared with the other smart watch.

On the other hand, the device preference can preferably be calculated by the following equation (2).

In Equation (2), l _i denotes the total number of times that the target device 300 i has shared content with peripheral devices, and c _ij denotes the total number of contents shared by the device i and the device j.

In other words, the similarity of Equation (2) indicates that the device preference (similarity) is determined based on the total number of times the contents are shared by the two devices when the target device 300 is present and the number of times the contents are shared between the two devices Value is obtained. The result value according to Equation 2 has a value between 0 and 1. The closer to 1, the higher the mutual preference between the two devices, and the closer to 0 the lower the preference.

As a result, the device preference calculated in step 2 is an index indicating how the target device 300 has more active content sharing with peripheral devices.

The third step of the heterogeneous device interworking method is to calculate the device reliability.

The device reliability is an index for grasping how high reliability can be shared when ultimately sharing information between the target device 300 and other devices. The device reliability is largely divided into two parameters: Can be defined as the sum of the degrees of similarity. Hereinafter, device participation and device similarity will be described.

FIG. 5 is a conceptual view of device participation. The device participation field indicates how many times the target device 300 has interworked with other devices, that is, the number of content sharing times in the network environment, and how many other devices in cooperation with the target device 300 share content Is an indicator for judging whether or not the user has performed the operation. That is, the device participation degree is high when the target device 300 has a large number of interoperability with other devices, particularly when interworking with other devices having a large number of interoperability is large.

The device participation degree can be preferably calculated by the following equation (3).

In Equation (3), d indicates the probability that the target device 300 can be connected to another device, and the value d has a value between 0 and 1. Also, DN (Device Network) means a set of devices existing on a network, and d _i means individual devices existing in the set. On the other hand, the Link (d _j ) means the number of other devices connected to the peripheral device d _j except for the target device 300, and the socialParticipation _j means the unique device participation value of the peripheral device d _j .

Next, FIG. 6 is shown for conceptual understanding of the device similarity. The device similarity is an indicator for determining whether or not the target device 300 is similar to other devices. This is used to select devices of a form capable of sharing contents with the target device 300 among various types of devices do. For example, if the target device 300 is a smart phone, if the other device is a smart phone of the same type, all the contents can be shared between the two devices regardless of the form of data such as video, image, audio, and text. The device similarity degree becomes high. On the other hand, if the target device 300 is a smartphone and the other device is a smart watch, contents such as audio and text can be easily shared between the two devices. However, since contents such as video and images are not easily shared, The device similarity value becomes relatively low.

(Smart phone, smart watch, portable computer, etc.) based on the type of content (video, image, text, etc.) that can be shared between devices, , Or the type of an operating system (OS) installed in the device. The criteria for determining the commonality between the devices can be variously set.

On the other hand, the device similarity degree can preferably be calculated by the following expression (4).

In Equation (4), ic _i denotes the total number of times the target device 300 i has interworked with other devices, ic _ij denotes a device (smart phone, smart watch, portable computer, The number of times the device 300 is interlocked. That is, the value of Equation 4 increases according to how frequently the target device 300 is interworked with other devices of the same type.

As described above, the heterogeneous device interworking method according to the present invention is a method of interacting with a target device 300 based on the device sociality indicating the degree of interworking of the target device 300 with other devices, A device preference indicating a degree of information sharing with the devices, and a device reliability indicating the degree of easiness of information sharing with the other devices of the target device 300. [ As a result, according to the present invention, the efficiency of information sharing in the first stage, the personalization of information sharing in the second stage, and the reliability of information sharing in the third stage are considered, thereby enabling interoperability between the more efficient and reliable heterogeneous devices .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention.
