The positioning module 211 determines the current position of the mobile device 200 and transmits the determined position information to the controller 180. [ Here, the location information may include at least one of latitude and longitude information, address information, and GPS positioning information. In addition, the positioning module 211 may select the position information having the highest accuracy among the position information collected or determined by the wireless communication unit 113. In addition, the positioning module 211 may determine which communication module collects the position information according to the reception state of the wireless signal for each communication module.

The location sharing screen generation module 213 maps the collected location information on a map when location information is collected from mobile devices having location sharing. That is, the location sharing screen generation module 213 can configure the screen so that the current location of the mobile device set in the location sharing is displayed on the map stored in the map database 220, and the configured screen is displayed through the display module 131 And can be output on the screen.

The radial departure determination module 215 performs a function of determining whether the corresponding mobile device is out of a predetermined radius of movement by using the location information and the reference location information received from the mobile device set by the location sharing. Here, the reference position information may be the current position information of the master terminal. Therefore, the radial deviation detection module 215 can determine whether there is a slave terminal that is outside a preset radius based on the current position of the master terminal.

The reference position information according to another embodiment of the present invention can be selected by a user through a predetermined user interface screen. At this time, the user can input specific address information or select a specific point on the map displayed on the screen through touch input or the like. If the address information is input by the user, the radial departure determination module 215 can acquire the position information on the map corresponding to the input address information by referring to the map database 220, May be displayed at corresponding locations on the map.

In the above description, the map database 220 is maintained in the mobile device 200. However, the map database 220 according to another embodiment of the present invention may be constructed in a separate map information providing server, The mobile device 220 may access the map information providing server and obtain coordinate information on the map corresponding to the address information.

The movement distance calculation module 217 calculates the movement distance of the mobile device 200. [ In detail, the movement distance calculation module 217 may calculate how much the mobile device 200 has moved from the point where the position information was finally transmitted.

For example, the slave terminal can transmit its location information to the master terminal only when the movement distance of the corresponding slave terminal calculated from the point at which the location information was last transmitted is greater than or equal to a predetermined reference value. Here, the reference value can be transmitted to the slave terminal using the push notification message by the master terminal. Therefore, according to the present invention, it is possible to control the transmission of location information according to the moving distance of the mobile device, so that the slave terminal having almost no movement transmits its position information to the master terminal more than necessary .

The push message processing module 217 generates a predetermined push notification message according to a control signal of the controller 180 or processes a push notification message received from the outside. The push notification message processing module 217 may analyze the content of the received push notification message and transmit the analysis result to the control unit 180. [ At this time, the controller 180 may control the operation of the lower module according to the analysis result.

For example, the push message processing module 217 notifies the control unit 180 of the received position information sharing request push message, and the controller 180 notifies the master unit of the position information sharing request message And transmits the generated pop-up notification message to the display module 131. If the user accepts the request through the pop-up notification window, the push message processing module 217 generates a location information sharing response push message including the acceptance information according to the control signal of the controller 180, ). Subsequently, the control unit 180 may transmit the location information sharing response push message to the master terminal through the wireless communication unit 113. [

The map database 220 is a recording medium for holding map information, and can provide map information corresponding to the position information or the address information according to the control signal of the controller 180.

The timer 230 drives the timer for a designated time according to the control signal of the controller 180 or generates a predetermined timer expiration event when the driven timer expires.

For example, when the location information transmission period of the slave terminal is previously set, the controller 180 may set an expiration period of the timer at the corresponding period, and the timer 230 may generate a predetermined timer expiration event when the timer expires. When the controller 180 detects the timer expiration event, the controller 180 may transmit a push notification message including the current location information to the master terminal. Here, the procedure of setting the location information transmission period of the slave terminal will be described in detail with reference to FIG.

Although only two slave terminals are shown in FIG. 3, at least one slave terminal is sufficient for convenience of description.

The master terminal 300 and the first and second slave terminals 330 and 340 receive GPS signals from the GPS network 350 through the installed GPS receiving module 119 and decode them to generate location information have.

When the location information sharing with the first and second slave terminals 330 and 340 is completed through the predetermined location information sharing request / response procedure, the master terminal 300 transmits the push server 320 and the wireless network 360 The location information of the first and second slave terminals 330 and 340 is collected.

The master terminal 300 generates a predetermined location information sharing push notification message including location information and location information collected from the first and second slave terminals 330 and 340, And transmits the generated location information sharing push notification messages to the first and second slave terminals 330 and 340 via the push server 320. [

The slave terminal 300 can map the location information included in the location information sharing push notification message on the map and display the map on the display screen.

4 is a flowchart illustrating a push service registration procedure according to an exemplary embodiment of the present invention.

Referring to FIG. 4, the mobile device 200 transmits a push service registration request message including a sender ID and an application software ID to the push server 320 (S401).

Here, the sender identifier is a project identifier obtained from an API (Application Program Interface) console, and is information used in a registration processing procedure to identify application software permitted to transmit a push message to a mobile device.

The application software identifier is application software identification information to register with the push server 320 to receive the push message. For example, for Google Android, the Android app can be identified by the package name defined in the manifest, which contains a summary of the entire assembly provided by the Android operating system provided by Google. Accordingly, when receiving the push notification message, the mobile device 200 can identify the push application software to process the push notification message.

The push server 320 generates an application software registration identifier corresponding to the received sender identifier and the application software identifier (S403).

Subsequently, the push server 320 transmits a predetermined push service registration response message including the application software registration identifier to the mobile device 200 (S405).

5A is a data structure of a push notification message according to an exemplary embodiment of the present invention.

The notification type 505 of the location information push message and the location information sharing push message according to another embodiment of the present invention may be set as a notification of the delivery of the mobile terminal 200. At this time, It is possible to display the location information by numeric characters on one side of the location information sharing application software icon.

On the other hand, in the case of the location information sharing request push message transmitted by the master terminal for location information sharing with the slave terminals, it is necessary to notify the slave terminal user that the push message requesting the sharing of location information is received from the master terminal But should accept an accept or reject input of the slave terminal user for the share request. Therefore, the notification type 505 for the location information sharing request push message is preferably set as a pop-up notification. The slave terminal user can confirm whether the location information sharing request has been received from the master terminal through the pop-up notification window, and enter the acceptance of the sharing request through the accept button and the reject button displayed in the pop-up notification window.

The frame length 507 is information indicating the total size of the push message. That is, the frame length 507 may be a value obtained by summing the sizes of the header and the payload.
