The present invention relates to a control method of a mobile communication terminal, and more particularly, to an application control method of a mobile communication terminal.

Bluetooth, using the IEEE 802.15.1 specification, is an industry standard for personal local area networks. Bluetooth enables a variety of devices to communicate with each other using radio frequencies that are available worldwide at a safe and low cost. Bluetooth uses 2.45GHz, the ISM band. Versions 1.1 and 1.2 reach 723.1 kilobits per second, and version 2.0 features an Enhanced Data Rate (EDR), which is 2.1 megabits per second.

The mobile communication terminal supporting Bluetooth has not received much attention, but it is recently attracting attention as it is combined with advanced technologies such as voice recognition technology and OTA (Over the Air) technology that can transmit and receive music files wirelessly. By equipping the mobile terminal with Bluetooth, hands-free function can be supported, and electronic business cards can be exchanged between desired people.

The physical connection of Bluetooth is created based on master / slave, and the master device can control up to seven slave devices. A network composed of such a master device and up to seven slave devices is called a piconet.

Referring to FIG. 1, a master device and a slave device each include a Bluetooth host and a Bluetooth controller. Again, the Bluetooth host consists of an application and a Bluetooth stack, and the Bluetooth controller includes a Bluetooth module.

An application is an application that works in conjunction with other Bluetooth devices via the Bluetooth stack. The application operates only according to an API (Application Programming Interface) abstracted by the Bluetooth stack or a predetermined Bluetooth Profile, and does not know about the operation of transmitting and receiving RF signals and Bluetooth connection occurring in the Bluetooth module. The Bluetooth profile is a wireless interface specification for connections between Bluetooth devices.

The Bluetooth stack is an actual implementation of the Bluetooth Protocol Stack, which may be configured as a hardware chip, but is typically implemented in the form of software. Common implementations include Widcomm, Microsoft Windows stack, EtherMind stack, Toshiba stack, BlueSoleil, and BlueZ. Examples of embedded devices are BlueMagic, lwBT, and BlueLet.

The Bluetooth stack acts as an interface between the application and the Bluetooth module. That is, the application provides data to or receives data from the Bluetooth module through the Bluetooth stack, which is an abstracted layer, and the Bluetooth module provides the provided data as an RF signal to another Bluetooth device or receives data from another Bluetooth device. Receive.

The Bluetooth module actually transmits and receives RF signals to other Bluetooth devices, and is typically implemented in the form of a hardware chip, but some functions may be implemented in the form of software.

It corresponds to the upper part of the Host Controller Interface (HCI) Layer. The Bluetooth protocol stack is omitted in the following description because it is described in detail in the Bluetooth standard.

3 is a conceptual diagram illustrating a transition of a Bluetooth connection state.

Referring to FIG. 3, a Bluetooth device not in the same piconet is connected in a standby mode, waiting for a message. When a Bluetooth device wants to connect with another Bluetooth device, it sends a Page message if it knows the address of the other Bluetooth device, or it sends an Inquiry message after the Page message. After entering the Connected mode, you can enter the Data Transfer mode where the data transfer takes place. Sniff mode is a state in which data transmission of the piconet is monitored while data transmission is not performed, but the piconet remains synchronized. In Hold mode, synchronization is completely maintained while data transmission is completely stopped. In Park mode, you are no longer an active member of the piconet, but watch the Broadcast channel while keeping it in sync with the master device.

Referring to FIG. 6, the Bluetooth stack operating in the mobile communication terminal first checks connection states of Bluetooth devices currently connected to the mobile communication terminal (S130). The checking process is performed via a Bluetooth module which is a lower layer on the Bluetooth protocol stack. For example, when a Bluetooth device connected to a mobile communication terminal becomes inoperable due to battery discharge, when the Bluetooth stack of the mobile communication terminal attempts to transmit and receive data, data transmission and reception failure occurs within a predetermined time. In this case, it may be determined that the communication is disconnected or the communication is restricted. For another example, the Bluetooth stack of the mobile communication terminal may determine that the Bluetooth device is abnormally terminated and enters the hold mode when the ACL link is not supported for more than a predetermined time.

Next, when there is a Bluetooth device in the restricted communication mode as a result of checking the connection state, the Bluetooth stack searches for an application that was connected with the Bluetooth device in the restricted communication mode (S140 and S150). The limited communication mode is a state in which synchronization within the piconet is not interrupted, but data transmission and reception are not actually performed, and may be any one of the Sniff mode, Hold mode, and Park mode described above.

As described above, even if the Bluetooth connection is abnormally terminated or the like, since the application does not directly give feedback on this state, the application continues to run on the mobile communication terminal. The Bluetooth stack obtains a list of applications currently running on the mobile communication terminal from a process list provided by an operating system (OS) of the mobile communication terminal or accesses a Bluetooth connection through the Bluetooth stack. The search operation can be performed by maintaining a list.

Next, the Bluetooth stack provides application control information to the found application (S170). The application control information may be at least one of information on a connection state with the Bluetooth device connected to the mobile communication terminal, an application pause event, and an application termination event.

For example, the information about the connection state with the Bluetooth device in the application control information may include information that the connection with the Bluetooth device connected to the mobile communication terminal corresponds to the Hold mode of the restricted communication mode. The application pause event and the application termination event are information for inducing an application to perform an operation of pausing or terminating. The processing of the event provides identification information and specific operation information of a specific application to an operating system of the mobile communication terminal. A request may be made to generate the event to the specific application.

In the Bluetooth connection, the Bluetooth stack serves as an interface between the application, the Bluetooth module, and other Bluetooth devices, so that a new Bluetooth connection can be recognized when a new Bluetooth connection is established.

The Bluetooth stack stores identification information of the Bluetooth device and identification information of the application when a new Bluetooth connection is established as a result of the determination (S120).

The identification information of the Bluetooth device may be at least one of a Bluetooth Passkey and a Personal Identification Number (PIN). The PIN is the key used to authenticate between two Bluetooth devices that have never exchanged a link key before. The PIN is used in the pairing process to create the first link used for identification. Bluetooth Passkey is a name when a PIN is used at a user interface (UI) level.

The identification information of the Bluetooth device may further include at least one of Bluetooth Device Class, Bluetooth Device Type, and Bluetooth Service Type. The Bluetooth Device Class, the Bluetooth Device Type, and the Bluetooth Service Type are parameter values indicating the type of the Bluetooth device and the service provided by the Bluetooth device, and generally mean Bluetooth Profiles.

The identification information of the application may be at least one of an authentication key of the application, an execution file name of the application, and a main execution window title of the application. The authentication key of the application means a key that is determined in advance by a qualified application provider and requires user input when installing or executing a specific application so that an application including malware, such as malware, cannot be arbitrarily installed and executed in a mobile communication terminal. do.

When there is a Bluetooth device in the restricted communication mode, in step S150 of searching for an application that is connected with the Bluetooth device, the search may be performed based on identification information of the stored Bluetooth device and identification information of the application. have. That is, when the identification degree is stored in the database (DB) or the like in the Bluetooth device identification information and the application identification information storage step 120, the search process is performed more quickly using the stored identification information in the application search step (S150). Can be performed.
