Various exemplary embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some exemplary embodiments are shown. The present inventive concept may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. Rather, these exemplary embodiments are provided so that this description will be thorough and complete, and will fully convey the scope of the present inventive concept to those skilled in the art.
Now, a method for being selectively connected to an AP and a mobile terminal by using the same according to exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a block diagram illustrating a configuration of a mobile terminal according to an exemplary embodiment of the present invention.
Embodiments of the present invention may be applicable to various types of portable terminals. Examples of such terminals may comprise mobile terminals such as mobile phones, smart phones, smart pad, notebook computers, digital broadcast terminals, PDAs (personal digital assistants), portable multimedia players (PMP) and/or navigators.
Referring to FIG.1, the mobile terminal (1) according to the present invention comprises a controller (10), a mobile communication unit (11), a wireless LAN connection unit (12), a position information unit (13), an acceleration sensor (14), a display unit (15), a user input unit (16), storage (17) and a Bluetooth® connection unit (18). It should be apparent to the skilled in the art that all the constituent elements illustrated in FIG.1 are not essential and a mobile terminal comprising more constituent elements than what is illustrated in FIG.1 may be realized.
The mobile communication unit (11) transmits a wireless signal to and receives a wireless signal from at least any one of a base station, an external terminal and a server via a mobile communication network. The wireless signal may comprise various data including a voice call signal, an image call signal or a signal for data communication. The wireless LAN connection unit (13) transmits and receives data for wireless Internet by being connected to a wireless AP (Access Point). The wireless LAN technology may comprise Wi-Fi, Wibro (Wireless Broadband Internet) and Wimax (World Interoperability for Microwave Access).
In the description of the present invention, it is assumed that the mobile communication unit (11) transmits and receives data, in a case the mobile terminal (1) receives data via a mobile communication network, and the wireless LAN connection unit (12) transmits and receives a data, in a case the data is received via a wireless LAN by being connected to a wireless AP.
The position information unit (13) serves to obtain a position of the mobile terminal (1). By way of non-limiting example, the position information unit (13) may include a GPS (Global Positioning System). The acceleration sensor (14) measures a speed of the mobile terminal (1) and transmits the speed to the controller (10).
The display unit (15) outputs information processed by the mobile terminal (1). By way of non-limiting example, in a case the mobile terminal (1) is under a call mode, the display unit (15) may output UI (User Interface) or GUI (Graphic User Interface) related to the call, and in a case the mobile terminal (1) is under a data communication mode, the display unit (15) may output a relevant UI or a relevant GUI. The display unit (15) may comprise at least one of an LCD (Liquid Crystal Display), a TFT-LCD (Thin Film Transistor-Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), a flexible display and a three dimensional (3D) display.
The user input unit (16) generates an input data for operational control, by a user, of the mobile terminal (1). The display unit (15) may be also realized by the user input unit (16), in a case a sensor detecting a touch operation (touch sensor) along with the display unit (15) is configured in a mutually layered structure. The storage (17) may store AP information blocking an access in response to control of the controller.
The Bluetooth® connection unit (18) is connected to a predetermined device (e.g., headset, speaker, etc.) via Bluetooth in response to a user selection to allow sound outputted from the mobile terminal (1) to be outputted to the predetermined device. The controller (10) generally controls an entire operation of the mobile terminal (1), and controls a selective AP connection according to the present invention. The operation of the controller (10) will be described hereinafter in detail with reference to the accompanying drawings.
The various exemplary embodiments of the present invention explained herein may be realized in hardware or as software or computer code that can be stored in a machine readable recording medium, or combination thereof.
The hardware described in connection with the aspects disclosed herein may be implemented or performed by any one of or with ASICs (Application Specific Integrated Circuits), DSPs (Digital Signal Processors), DSPDs (Digital Signal Processing Devices), PLDs (Programmable Logic Devices), FPGSs (Field Programmable Gate Arrays), controllers, micro-controllers, microprocessors, and other electrical units for performing the functions described herein. Some of the exemplary embodiments of the present invention may be implemented by the controller (10) itself.
According to the software described in connection with the aspects disclosed herein, various exemplary embodiments of the present invention explained herein such as processes and functions may be realized by separate software modules. Each of the software modules may implement one or more functions or operations described herein. The software code may be implemented using software application using any adequate programmable language. The software code may be stored in the storage (17), and may be carried out by the controller (10).
FIG.2 is a schematic view illustrating a mobile terminal passing AP coverage according to an exemplary embodiment of the present invention.
Generally, a user holding a mobile terminal (1) moves within a predetermined moving radius. By way of non-limiting example, an office worker has a moving route predetermined for reporting to work or discharging from work, and a student has a moving route predetermined for going to school or coming home from school, where they generally use these routes. That is, a user using a predetermined route may pass a predetermined AP coverage positioned at a relevant route.
Referring to FIG.2, in a case that is exemplified where a user holding a mobile terminal (1) regularly moves within a coverage (A) provided with a wireless LAN service by a predetermined AP (21), the mobile terminal (1) enters the coverage (A) of the AP (21) at B and exits at C, where the mobile terminal (1) receives data via the mobile communication unit (11), connects to the AP (21) at B via the wireless LAN connection unit (12), and releases connection to the AP (21) at C.
Because the user holding the mobile terminal (1) is in a moving state, the connection at B and connection release at C are implemented at a very short period of time, which ill affects reception of data.
The controller (10) according to the present invention stores information of the AP (21) arranged on a moving route generally used by a user, checks the information of AP to be connected, and blocks the connection to a relevant AP (21), in a case the user enters the coverage (A) of the relevant AP (21) while the user is moving.
Now, the method for being selectively connected to an AP according to an exemplary embodiment of the present invention will be described with reference to drawings.
FIG.3 is a flow chart illustrating a method for being selectively connected to an AP according to a first exemplary embodiment of the present invention.
Referring to FIG.3, the controller (10) according to the present invention may receive information of an AP within a moving radius frequented by a user, and store the information in the storage (17) (S31). Generally, an AP continuously transmits its own information, such that the mobile terminal (1) can receive information on the AP via the mobile communication unit (11), where the controller (10) can store the information in the storage (17).
The controller (10) may guide information of an AP frequently connected by the wireless LAN connection unit (12) of the mobile terminal (1) on a configuration menu to a user via the display unit (15), display (not shown) a message inquiring the user whether to block the connection in case of being connected to a relevant AP while the user is moving, and store the information of the AP in the storage (17) according to user selection.
Although the present invention has illustrated and exemplified a case where information on AP within a moving radius is stored, the present invention is not limited thereto. By way of non-limiting example, relevant AP information may be stored in the storage (17) out of the moving radius according to user selection to block connection to a predetermined AP.
Successively, the controller (10) determines whether the mobile terminal (1) held by the user is moving (S32). By way of non-limiting example, the controller (10) may determine whether the user is moving using a position of the mobile terminal (1) received from the position information unit (13), or may determine whether the user is moving using acceleration of the mobile terminal (1) received from the acceleration sensor (14) in a case the acceleration exceeds a predetermined acceleration.
Furthermore, the controller (10) may determine whether the user is moving in a case the Bluetooth® connection unit (18) is connected to a speaker mounted at a vehicle. In addition, the controller (10) may determine whether the user is moving, using a time when the wireless LAN connection unit (12) of the mobile terminal (1) is connected to and released from a predetermined AP. That is, the controller (10) may determine whether the user is moving, if a time connected to and released from a predetermined AP is shorter than a predetermined time, because the time connected to and released from a predetermined AP may be a short time in a case the user is moving. In addition, various methods of determining, by the controller, whether the user holding a mobile terminal (1) is moving, may be provided.
As a result of determination as S32, if it is determined that the user holding a mobile terminal (1) is moving, the controller (10) may receive and track information of AP within a moving radius using the mobile communication unit (11) (S33).
If it is determined by the controller (10) that the stored information on AP at S31 has been received (S34), the controller (10) may block connection to the AP by the wireless LAN connection unit (12) (S35).
According to the present invention, the connection to an AP arranged within a moving radius is blocked to relieve a user from manually turning on/off the mobile terminal (1) by preventing the wireless LAN connection unit (12) from being unnecessarily connected to the wireless LAN.
Meanwhile, connection to actually inoperable AP can be prevented by a method for being selectively connected to an AP according to the present invention.
FIG. 4 is a flow chart illustrating a method for being selectively connected to an AP according to a second exemplary embodiment of the present invention.
Referring to FIG. 4, the controller (10) according to the present invention may transmit (S42) a signal requesting connection to an AP, in a case the mobile terminal enters coverage of the AP and receives information of the AP (S41).
Successively, the controller (10) may determine whether there is a response from the AP (S43). If there is no response, the controller (10) may block the connection by the wireless LAN connection unit (12) (S44). Although the present invention has described the blocking to the connection if there is no response one time, the request may be re-transmitted to determine whether there is a response if reception of the response fails, and the controller (10) may block the connection to the AP, in a case the response to the request is not received more than predetermined times (threshold).
If there is a response from the AP in S43, the controller (10) may allow connection to the AP by the wireless LAN connection unit (12) (S45).
According to the present invention, a section, where data is not received by accessing to an inoperable AP, is prevented in advance from being generated, by monitoring a response to a request and accessing to only an actually operable AP by determining whether an AP is actually operable.
The previous description of the present invention is provided to enable any person skilled in the art to make or use the invention. Various modifications to the invention will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other variations without departing from the spirit or scope of the invention. Thus, the invention is not intended to limit the examples described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
