Hereinafter, a mobile terminal and a communication system including the same according to the present invention will be described in detail with reference to the drawings.

The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role.

In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

1 illustrates a communication system related to an embodiment of the present invention in which an AP 210 of a mobile terminal 200 is activated using a payload 101 transmitted from a BLE module 120 of a server 100 And FIG. 2 is a block diagram showing an AP start-up system for activating the AP 210 of the mobile terminal 200 shown in FIG.

Referring to Figures 1 and 2, the communication system includes a server 100 and a plurality of mobile terminals 200A-N. For example, the server 100 may be a workstation, a desktop computer acting as a master device, a notebook computer, a tablet PC, or the like. In addition, each of the mobile terminals 200A-N can perform a function as a slave device.

The server 100 is configured to activate an AP (Application Processor) 210 to each mobile terminal 200 and request a connection with the server 100. Each mobile terminal 200 receives the request, 210 are activated. In addition, the server 100 and each mobile terminal 200 have a protocol for waking up the corresponding AP 210.

The server 100 includes a processor 110 and a BLE module 120.

The processor 110 is configured to generate a payload 101 to be transmitted to the mobile terminals 200A-N. The BLE (Bluetooth Low Energy) module 120 is configured to advertise the payload 101 to the mobile terminals 200A-N. The BLE module 120 may include, for example, a BT (Bluetooth) device having a BLE function, and may be implemented as a dongle that is easily removable as needed.

The server 100 includes a DB (Data Base) 142 capable of pairing the server 100 and the mobile terminals 200A-N, and a memory 140 for storing the DB. For example, the DB 142 may include a BDADDR (Bluetooth Device ADDRESS) and a PIN code (Personal Identification Number) of each of the mobile terminals 200A-200N. The pairing of the server 100 and each mobile terminal 200 is performed based on the identification code (e.g., BDADDR, PIN code, etc.) of the mobile terminal 200. [

The BDADDR may include network addresses of devices having a BT function such as the mobile terminals 200A-N. For example, BDADDR may be configured with a unique number (e.g., 48 bits) used to specify a particular device for connection, pairing or AP 210 activation. In addition, the PIN code may be composed of a four-digit personal ID code based on the serial number of the mobile terminal 200 and the version of the OS of the mobile terminal 200 to be downloaded.

The BLE module 120 is configured to transmit a payload 101 comprising at least a portion of the DB 142 to the mobile terminals 200A-N. For example, the payload 101 may include a BDADDR of each of the mobile terminals, a Wi-Fi AP (Access Point) BSSID (Basic Service Set Identifier) of the server, and an IP (Internet Protocol) address of the server.

BLE proposes a new low-power Bluetooth specification that improves the relatively power-hungry parts of conventional Bluetooth while maintaining stability and security, which are advantages of Bluetooth. The BLE separates the data channel from the advertising channel. The BLE module 120 is configured to transmit the payload 101 through at least one of the transmission channels 37, 38, and 39 using the characteristics of the BLE.

The BLE module 120 is configured to transmit the payload 101 to a plurality of unspecified mobile terminals 200A-N through a transmission channel (Discovery Undirected Event Type). When the mobile terminals 200A-N receive the payload 101 and are determined to be valid (if it is determined that the payload 101 is applicable), the mobile terminals 200A-N are activated to activate the AP 210. [

Each mobile terminal 200 has an AP activation system that activates the AP 210. The AP startup system includes an AP 210, a communication module 220, a potential measurement sensor 240, a PMIC (Power Management Integrated Circuit) 250, and a controller 260.

The AP 210 may include one or more of a core, a memory, a display system / controller, a multimedia encoding / decoding codec, a 2D / 3D accelerator engine, an ISP (Image Signal Processor), a camera, / Parallel connection interface, and the like.

The communication module 220 is configured to communicate with the server 100 through the BLE module 120. The communication module 220 may be a BT device 221 having a BLE function such that the BLE module 120 consumes a minimum amount of power. The BT device 221 having the BLE function consumes only a fraction (e.g., 1 to 5 percent) of the power consumed by the general BT device, so that it can communicate with the BLE module 120 with a minimum amount of power.

A battery 270 for supplying power to the mobile terminal 200 is built in or detachably mounted inside the mobile terminal 200. The battery 270 is packaged with the mobile terminal 200 built-in or mounted. The battery 270 is charged with a certain level of power and the battery 270 is supplied with a quiescent current through the PMIC 250 until the AP 210 is activated. The fact that the AP starting system that activates the AP 210 can be maintained for a long time is due to its longevity with the minimum current generated in the battery 270, that is, the constant operating current.

The mobile terminal 200 processes the payload 101 transmitted from the server 100 and controls the controller 260 to activate the AP 210 of the mobile terminal 200 if the payload 101 is valid ). The controller 260 may be configured as an example of a controller for controlling overall operations related to upgrading such as communication with the server 100 and downloading a specific program. The controller 260 may enable the communication module 220 to receive the payload 101 from the server 100 in the standby mode and activate the AP 210 if the payload 101 is valid The signal from the server 100 is monitored.

The PMIC 250 is configured to control the power supply to the AP 210. For example, when the communication module 250 receives the payload 101 from the server 100, it compares the measured potential of the battery 270 with the reference value through the potential measurement sensor 240, And controls the power supply to the AP 210. [

The PMIC 250 may be configured to apply a power supply to the AP 210 only when the measured potential is greater than or equal to a reference value. For example, the battery 250 maintains a certain level of power over a certain remaining amount. When the power of the battery 270 falls below the reference value because the mobile terminal 200 is kept in stock for a long time, the power can be interrupted in the middle of downloading the software from the server 100. [ The PMIC 250 compares the measured potential with a reference value and maintains a shutdown state (or a state of supplying a positive operation current) without applying power supply when the remaining amount of the battery 270 is insufficient, Thereby preventing a malfunction due to a failure.

The communication module 220 may be configured to transmit the measured potential to the server 100. The server 100 may separately manage the mobile terminals 200A-N that have insufficient remaining capacity of the battery 270 based on the measured potentials of the transmitted mobile terminals 200A-N.

The AP startup system may further include a power switch 290, an LDO (Low Drop Out) 282, and a switch 281. The power switch 290 is connected to the PMIC 250 and selectively supplies power to the AP 210. The power switch 290 may be implemented as an operation key exposed to the outside of the mobile terminal 200. The LDO 282 is configured to supply the power required for operation of the communication module 220. The switch 281 is opened between the AP 210 and the communication module 220 before the AP 210 is activated and is closed after the AP 210 is activated. For example, when the communication module 220 receives the valid payload 101 from the BLE module 120 of the server 100 and the AP 210 is activated, the Wi-Fi module 230 transmits the payload 101 to the server 100 And transmits the updated OS to the AP 210.

The server 100 includes a Wi-Fi module 130 and each of the mobile terminals 200A-N includes a Wi-Fi module 230. [ The BT device 221 is difficult to receive a large amount of data and the AP 210 is activated and after the server 100 and the mobile terminal 200 are paired, the Wi-Fi modules 120 and 230 The program stored in the server 100 is transmitted to the mobile terminal 200. The program may be, for example, an updated OS or a specific application.

Although the above description has been made on the basis of one server 100 and the mobile terminal 200 connected thereto, the execution of the pairing or program downloading operation can be performed simultaneously or simultaneously with the plurality of mobile terminals 200A-N illustrated in FIG. Can be performed sequentially.

Hereinafter, a communication system capable of activating the AP 210 of a plurality of mobile terminals 200A-N by one transmission without individual pairing will be described in more detail.

3 to 5 are flowcharts showing examples in which the controller 260 of FIG. 1 controls activation of the AP 210 using the payload 101. FIG.

Referring to FIG. 3, the server 100 is configured to transmit the payload 101 to a plurality of unspecified mobile terminals 200A-N through a transmission channel of the BLE module 120. FIG. The BLE module 120 may be configured to transmit the payload 101 to the mobile terminals 200A-N at predetermined time intervals. The transmission of the payload 101 may continue until all of the mobile stations 200A-N to which the AP 210 activates send a response signal (Scan Request, Acknowledge).

The BLE module 120 may be configured to advertise with a Discovery Undirected Event Type. According to the above method, the mobile terminals 200A-N receiving the payload 101 function as a scanner for supporting active scanning. the advertiser server 100 may activate the AP 210 in a connectless manner as short as possible via advertising.

The payload 101 may include an identification code of each of the mobile terminals 200A-N, information for communication with the server 100, and the like, as described above. Specifically, the processor 110 transmits only the BDADDR of the mobile terminals 200A-N to which the AP 210 is to be activated among the identification codes of the mobile terminals 200A-N stored in the DB 142, for example, The payload 101 is generated. When the AP 210 is activated in the payload 101, information for connection with the server 100, for example, a Wi-Fi AP BSSID and an IP address are transmitted to the server 100 so as to be able to communicate with the server 100 .

The payload 101 is transmitted to a plurality of unspecified mobile terminals 200A-N through the transmission channel of the BLE module 120 and the communication module 220 of each of the mobile terminals 200A-N And is configured to receive the payload 101 transmitted from the server 100. The controller 260 monitors the payload 101 received via the communication module 220 in the idle mode and is set to activate the AP 210 if the payload 101 is valid.

For example, the controller 260 is configured to activate the AP 210 when the BDADDR included in the payload 101 corresponds to the BDADDR of the communication module 220. If there is nothing corresponding to the BDADDR of the communication module 220 among the BDADDRs included in the payload 101, it can be reported to the server 100 and set to be kept in the standby mode.

Thus, through the advertisement of the BLE module 120, the AP 210 of a plurality of mobile terminals 200A-N can be activated by one transmission without individual pairing. When the AP 210 is activated, the communication module 220 may be configured to transmit a response signal to the server 100 indicating that the payload 101 has been received. The response signal may be configured to receive additional information by sending a scan request to an advertiser, that is, the server 100, after receiving the payload 101. In addition, the server 100 may be configured to transmit a response signal for the scan request, i.e., a scan response (e.g., 0 or a null value).

After that, the mobile terminals 200A-N are ready to communicate with the server 100 by activating the Wi-Fi module 230. [ For example, the mobile terminal 200 is connected to the server 101 through the Wi-Fi AP BSSID and the IP address of the server 101 included in the payload 101. The connection mode may be an infrastructure mode through an access point (AP) of the server 100 or an ad-hoc mode, which is a direct connection between the Wi-Fi modules 130 and 230.

When the server 100 and the mobile terminal 200 are paired, the program stored in the server 100 is transmitted to the mobile terminal 200 through the Wi-Fi modules 130 and 230. The program may be, for example, an updated OS or a specific application. The communication module 220 may be configured to report to the server 100 that the download of the program is completed when the download of the program is completed.

In FIGS. 4 and 5, modified examples in which the controller 260 controls activation of the AP 210 using the payload 101 will be described based on the control method. In other embodiments of the present invention, the same or similar reference numerals are given to the same or similar components as those of the previous embodiment, and the description thereof is omitted.

Referring to FIG. 4, the BLE module 120 includes first and second BLE devices 121 and 122, each having a different transmission channel. The first and second BLE devices 121 and 122 are each adapted to transmit the payload 101 via at least one of the transmission channels 37, 38 and 39 of the BLE.

The first and second BLE devices 121 and 122 may be configured to transmit the same payload 101 to each other. In this case, the transmission range of the payload 101 is enlarged, which has the advantage that more APs 210 can be activated for the same amount of time.

The first and second BLE devices 121 and 122 may be configured to transmit different first and second payloads 101a and 101b, respectively. For example, the second payload 101b may be configured such that at least one of the identification codes of the mobile terminals 200A-N and the information for connection with the server 100 is configured differently from the first payload 101a .

The first and second BLE devices 121 and 122 are controlled by the control method previously described with reference to FIG. However, the second BLE device 122 may be configured such that a plurality of mobile terminals 200A-N communicate with the first BLE device 121 and then communicate with the second BLE device 122 at predetermined intervals And may be configured to transmit the payload 101 to a plurality of mobile terminals 200A-N.

For example, when a plurality of programs are scheduled to be downloaded to the mobile terminals 200A-N, and in particular when the programs need to be downloaded in a certain order, the control method can be used.

Specifically, the first BLE device 121 is configured to transmit the first payload 101a to a plurality of unspecified mobile terminals 200A-N. The controller 260 activates the AP 210 when the BDADDR of the first payload 101a corresponds to the BDADDR of the communication module 220 and the communication module 220 transmits a response signal to the server 100 Respectively. The mobile terminals 200A-N are configured to download the first program through the first Wi-Fi module 131 of the server 100. [ When the download is completed, the communication module 220 transmits the first program download completion signal to the server 100, and the AP 210 returns to the inactive state, that is, the standby mode.

The server 100 detects the completion signal and the second BLE device 122 is configured to transmit the second payload 101b. The second payload 101b includes the BDADDR of the mobile terminals 200A-N that need to download the second program. The controller 260 activates the AP 210 when the second payload 101b is determined to be valid and the communication module 220 transmits a response signal to the server 100. [ The mobile terminals 200A-N are set to download the second program via the second Wi-Fi module 132 of the server 100. [ When the download is completed, the communication module 220 transmits the second program download completion signal to the server 100, and the AP 210 is switched to the standby mode.

As such, the number of mobile terminals 200A-N that can be processed can be increased by advertising the first and second BLE devices 121 and 122 through a plurality of transmission channels. In addition, since different operations are performed through physically independent transmission channels, interference can be minimized and processing speed can be improved.

Referring to FIG. 5, a plurality of mobile terminals 200A-N are divided into first and second groups 200a and 200b. The payloads 101a and 101b transmitted respectively by the first and second BLE devices 121 and 122 include BDADDRs of the first and second groups 200a and 200b, respectively. The first and second BLE devices 121 and 122 are configured to transmit the first and second payloads 101a and 101b to a plurality of unspecified mobile terminals 200A-N, respectively.

The controller 260 of the mobile terminals 200A-N activates the AP 210 when the received first and second payloads 101a and 101b correspond to the BDADDR of the communication module 220 . For example, if the BDADDR of the first payload 101a corresponds to the BDADDR of the communication module 220, it corresponds to the first group 200a and the first program is downloaded from the server 100. [ If the BDADDR of the second payload 101b does not correspond to the first group 200a but corresponds to the BDADDR of the communication module 220 corresponds to the second group 200b, And is set to download the program. The mobile terminal 200 which does not correspond to any group can be made to report the information to the server 100. The server 100 stores the state of each mobile terminal 200 in the memory 140 and can separately manage the state.

The mobile terminal and the communication system including the mobile terminal described above are not limited to the configurations and methods of the embodiments described above, but the embodiments may be modified such that all or some of the embodiments are selectively combined .
