Recently, as smart phones or mobile terminals having a comparable performance have been widely used, it has become common to install various applications in the mobile terminals. In addition, with the development of wireless communication technology, it is possible to temporarily configure a network between mobile hosts without the help of a base station or a wired network. An example of such a network configuration is a network as shown in FIG. 4. Mobile hosts in such a network can share data of a specific application with each other. An example of the ad hoc network described above is an ad-hoc network. Hereinafter, in this specification, a temporary network configured between mobile hosts will be collectively referred to as an ad hoc network. The mobile terminal 100 according to the present invention may participate in an ad hoc network through any one module (for example, a short range communication module) of the wireless communication unit 110 described above.

First embodiment

An embodiment of the present invention provides a mobile terminal and a control method thereof capable of efficiently exchanging information on a specific place through an ad hoc network configured with other terminals.

In order to implement this, in this embodiment, a volatile application is defined. The volatile application refers to an application that can obtain relatively low-capacity location-specific information from the outside and update the acquired region-specific information through an ad hoc network. Such a volatile application may operate in a form of automatically downloading region specific information from the outside as the mobile terminal enters an arbitrary region and automatically deleting region specific information as the mobile terminal leaves the region. As a method of determining whether the terminal has entered or exited a specific area in which a volatile application is supported, a transmission device such as a fixed access point (AP) that broadcasts a predetermined signal indicating that the area supports the volatile application is detected. It can be implemented in a way. At this time, the volatile application (ie, region specific information) may be provided from the transmitter.

As a form of installation of a volatile application, 1) as described above, only a region specific information (Description Document) describing a service is downloaded according to a place with a base holder residing in a mobile terminal pre-installed, 2) There is a form in which the base application and the region specific information are integrally installed without a separate pre-installed application in the terminal.

In this case, when the first method is applied, information (ie, region specific information) downloaded when entering the corresponding region may be minimized by residing in the mobile terminal through the installation of the base application. In addition, problems and troublesome security and authentication associated with installing the application may also be solved.

Specific examples of the above-described place specifying information will be described with reference to Table 1 below.

-Alarm service can be provided for emergency situations (ex. Fire) Restaurants / Taverns Employee Call / Menu Order Can replace the bell service for employee calls Public toilet Notification of use The user can know whether to use the area at the same time as entering the public toilet.

Hereinafter, a transmission apparatus for broadcasting a predetermined signal so as to know whether the terminal has entered its area, such as a fixed access point (AP), and distributing the area-specific volatile application or area-specific information therefor for convenience. In the following, it is referred to as "distribution server", and the area in charge of the corresponding distribution server is called "server area".

5 is a flowchart illustrating an example of a method of sharing place specifying information through a temporary network according to an embodiment of the present invention.

In FIG. 5, the distribution server in charge of a predetermined server area distributes region specific information for volatile applications to terminals 2 and 3, respectively, and the region specific information is updated through an ad hoc network formed between the terminals 2 and 3. Assume (S501).

At this time, the terminal 1 newly enters the server area of the distribution server (S502).

The terminal 1 detects a signal broadcast from the distribution server and recognizes that the terminal 1 enters the server area of the distribution server (S503).

Accordingly, the terminal 1 may request region specific information from the distribution server, and the distribution server transmits region specific information specific to the service provided in the server region to the terminal 1 (S504).

The terminal may participate in the ad hoc network configured by the terminal 2 and the terminal 3 in the server region in order to activate the volatile application using the region specific information provided by the distribution server and to update the information about the volatile application (S505).

When the terminal 1 participates in the ad hoc network, the region specific information may be updated by performing data exchange with the terminal 2 and the terminal 3 on the region specific information (S506).

Thereafter, the terminal 1 may leave the server area. In this case, when the broadcast signal cannot be received from the distribution server, the terminal 1 may determine that the server 1 is out of the server area (S507).

Accordingly, the terminal 1 may delete the region specific information (S508).

The above-described process has been described on the assumption that the area specifying information to the service technician is downloaded from the distribution support in the state where the base holder of the volatile application is equipped. If the volatile application itself is downloaded without the base holder, in step S504, the distribution server requests and receives the volatile application including the region specific information instead of the region specific information. At this time, the installation of the downloaded application may further include an authentication procedure for security. In addition, in step S508 may be a process of removing the application itself, rather than deleting the region-specific information.

Next, specific forms in which region-specific information appears on a volatile application will be described with reference to FIGS. 6A to 6C.

6A illustrates an example in which region specific information about a performance hall is displayed in a mobile terminal according to an embodiment of the present invention.

In FIG. 6A, it is assumed that a seat arrangement table of a performance hall is provided as region specific information. In this case, whether the seat assigned to the user or the seat by another person is not displayed. In this case, the user can get information about which driveway and route to use to go to his seat.

6B illustrates an example in which region specific information on a library seat is displayed in a mobile terminal according to an embodiment of the present invention.

In FIG. 6B, it is assumed that the library seat arrangement table is provided as area specific information. At this time, by sharing information about the seat occupied by each user through the ad hoc network, the user can know where the vacancy is. If the user selects a desired seat among the empty seats, information that the seat selected by the user is occupied through the ad hoc network may be shared with other users.

6C illustrates an example in which text-based area specifying information about a library seat is displayed in a mobile terminal according to an embodiment of the present invention.

Although FIG. 6C may represent the same information as FIG. 6B, in order to minimize the capacity of the area-specific information to be downloaded, the text-based table may indicate a seat occupancy state. Here, the user can know the empty seat by referring to the selectable column, and can notify other users of the update of the selectable column through the ad hoc network by selecting a column corresponding to the selectable seat.
