DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. It is to be understood by those of ordinary skill in this technological field that other embodiments may be utilized, and structural, electrical, as well as procedural changes may be made without departing from the scope of the present invention. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
First of all, a communication device according to one embodiment of the present invention can include a mobile type or a fixed type in accordance with a presence or non-presence of its mobility. The following description is made on the assumption that a communication device includes a mobile terminal for example. And, it is to be understood that various implementations of the present invention are not limited to the mobile terminal.
FIG. 1 is a block diagram of mobile terminal 100 in accordance with an embodiment of the present invention. The mobile terminal may be implemented using a variety of different types of terminals. Examples of such terminals include mobile phones, user equipment, smart phones, computers, digital broadcast terminals, personal digital assistants, portable multimedia players (PMP) and navigators. By way of non-limiting example only, further description will be with regard to a mobile terminal. However, such teachings apply equally to other types of terminals. FIG. 1 shows the mobile terminal 100 having various components, but it is understood that implementing all of the illustrated components is not a requirement. Greater or fewer components may alternatively be implemented.
FIG. 1 shows a wireless communication unit 110 configured with several commonly implemented components. For instance, the wireless communication unit 110 typically includes one or more components which permits wireless communication between the mobile terminal 100 and a wireless communication system or network within which the mobile terminal is located.
The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel. The broadcast managing entity refers generally to a system which transmits a broadcast signal and/or broadcast associated information. Examples of broadcast associated information include information associated with a broadcast channel, a broadcast program, a broadcast service provider, etc. For instance, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) and electronic service guide (ESG) of digital video broadcast-handheld (DVB-H).
The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. If desired, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal.
The broadcast receiving module 111 may be configured to receive broadcast signals transmitted from various types of broadcast systems. By non-limiting example, such broadcasting systems include digital multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcast-handheld (DVB-H), the data broadcasting system known as media forward link only (MediaFLO®) and integrated services digital broadcast-terrestrial (ISDB-T). Receiving of multicast signals is also possible. If desired, data received by the broadcast receiving module 111 may be stored in a suitable device, such as memory 160.
The mobile communication module 112 transmits/receives wireless signals to/from one or more network entities (e.g., base station, Node-B). Such signals may represent audio, video, multimedia, control signaling, and data, among others.
The wireless internet module 113 supports Internet access for the mobile terminal. This module may be internally or externally coupled to the terminal.
The short-range communication module 114 facilitates relatively short-range communications. Suitable technologies for implementing this module include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee, to name a few.
Position-location module 115 identifies or otherwise obtains the location of the mobile terminal. If desired, this module may be implemented using global positioning system (GPS) components which cooperate with associated satellites, network components, and combinations thereof.
Audio/video (A/V) input unit 120 is configured to provide audio or video signal input to the mobile terminal. As shown, the A/V input unit 120 includes a camera 121 and a microphone 122. The camera receives and processes image frames of still pictures or video.
The microphone 122 receives an external audio signal while the portable device is in a particular mode, such as phone call mode, recording mode and voice recognition. This audio signal is processed and converted into digital data. The portable device, and in particular, A/V input unit 120, typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal. Data generated by the A/V input unit 120 may be stored in memory 160, utilized by output unit 150, or transmitted via one or more modules of communication unit 110. If desired, two or more microphones and/or cameras may be used.
The user input unit 130 generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel and a jog switch. A specific example is one in which the user input unit 130 is configured as a touchpad in cooperation with a touchscreen display (which will be described in more detail below).
The sensing unit 140 provides status measurements of various aspects of the mobile terminal. For instance, the sensing unit may detect an open/close status of the mobile terminal, relative positioning of components (e.g., a display and keypad) of the mobile terminal, a change of position of the mobile terminal or a component of the mobile terminal, a presence or absence of user contact with the mobile terminal, orientation or acceleration/deceleration of the mobile terminal. As an example, consider the mobile terminal 100 being configured as a slide-type mobile terminal. In this configuration, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include the sensing unit 140 sensing the presence or absence of power provided by the power supply 190, the presence or absence of a coupling or other connection between the interface unit 170 and an external device.
The interface unit 170 is often implemented to couple the mobile terminal with external devices. Typical external devices include wired/wireless headphones, external chargers, power supplies, storage devices configured to store data (e.g., audio, video, pictures, etc.), earphones, and microphones, among others. The interface unit 170 may be configured using a wired/wireless data port, a card socket (e.g., for coupling to a memory card, subscriber identity module (SIM) card, user identity module (UIM) card, removable user identity module (RUIM) card), audio input/output ports and video input/output ports.
The output unit 150 generally includes various components which support the output requirements of the mobile terminal. Display 151 is typically implemented to visually display information associated with the mobile terminal 100. For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a user interface or graphical user interface which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 100 is in a video call mode or a photographing mode, the display 151 may additionally or alternatively display images which are associated with these modes.
One particular implementation includes the display 151 configured as a touch screen working in cooperation with an input device, such as a touchpad. This configuration permits the display to function both as an output device and an input device.
The display 151 may be implemented using known display technologies including, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display. The mobile terminal may include one or more of such displays. An example of a two-display embodiment is one in which one display is configured as an internal display (viewable when the terminal is in an opened position) and a second display configured as an external display (viewable in both the open and closed positions).
FIG. 1 further shows output unit 150 having an audio output module 152 which supports the audio output requirements of the mobile terminal 100. The audio output module is often implemented using one or more speakers, buzzers, other audio producing devices, and combinations thereof. The audio output module functions in various modes including call-receiving mode, call-placing mode, recording mode, voice recognition mode and broadcast reception mode. During operation, the audio output module 152 outputs audio relating to a particular function (e.g., call received, message received, and errors).
The output unit 150 is further shown having an alarm 153, which is commonly used to signal or otherwise identify the occurrence of a particular event associated with the mobile terminal. Typical events include call received, message received and user input received. An example of such output includes the providing of tactile sensations (e.g., vibration) to a user. For instance, the alarm 153 may be configured to vibrate responsive to the mobile terminal receiving a call or message. As another example, vibration is provided by alarm 153 responsive to receiving user input at the mobile terminal, thus providing a tactile feedback mechanism. It is understood that the various output provided by the components of output unit 150 may be separately performed, or such output may be performed using any combination of such components.
The memory 160 is generally used to store various types of data to support the processing, control, and storage requirements of the mobile terminal. Examples of such data include program instructions for applications operating on the mobile terminal, contact data, phonebook data, messages, pictures, video, etc. The memory 160 shown in FIG. 1 may be implemented using any type (or combination) of suitable volatile and non-volatile memory or storage devices including random access memory (RAM), static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disk, card-type memory, or other similar memory or data storage device.
The controller 180 typically controls the overall operations of the mobile terminal. For instance, the controller performs the control and processing associated with voice calls, data communications, video calls, camera operations and recording operations. If desired, the controller may include a multimedia module 181 which provides multimedia playback. The multimedia module may be configured as part of the controller 180, or this module may be implemented as a separate component.
The power supply 190 provides power required by the various components for the portable device. The provided power may be internal power, external power, or combinations thereof.
Various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or some combination thereof. For a hardware implementation, the embodiments described herein may be implemented within one or more application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, other electronic units designed to perform the functions described herein, or a selective combination thereof. In some cases, such embodiments are implemented by controller 180.
For a software implementation, the embodiments described herein may be implemented with separate software modules, such as procedures and functions, each of which perform one or more of the functions and operations described herein. The software codes can be implemented with a software application written in any suitable programming language and may be stored in memory (for example, memory 160), and executed by a controller or processor (for example, controller 180).
Mobile terminal 100 may be implemented in a variety of different configurations. Examples of such configurations include folder-type, slide-type, bar-type, rotational-type, swing-type and combinations thereof. For clarity, further disclosure will primarily relate to a slide-type mobile terminal. However such teachings apply equally to other types of terminals.
FIG. 2 is a perspective view of a front side of a mobile terminal according to an embodiment of the present invention. In FIG. 2, the mobile terminal 100 is shown having a first body 200 configured to slideably cooperate with a second body 205. The user input unit (described in FIG. 1) is implemented using function keys 210 and keypad 215. The function keys 210 are associated with first body 200, and the keypad 215 is associated with second body 205. The keypad includes various keys (e.g., numbers, characters, and symbols) to enable a user to place a call, prepare a text or multimedia message, and otherwise operate the mobile terminal.
The first body 200 slides relative to second body 205 between open and closed positions. In a closed position, the first body is positioned over the second body in such a manner that the keypad 215 is substantially or completely obscured by the first body 200. In the open position, user access to the keypad 215, as well as the display 151 and function keys 210, is possible. The function keys are convenient to a user for entering commands such as start, stop and scroll.
The mobile terminal 100 is operable in either a standby mode (e.g., able to receive a call or message, receive and respond to network control signaling), or an active call mode. Typically, the mobile terminal 100 functions in a standby mode when in the closed position, and an active mode when in the open position. This mode configuration may be changed as required or desired.
The first body 200 is shown formed from a first case 220 and a second case 225, and the second body 205 is shown formed from a first case 230 and a second case 235. The first and second cases are usually formed from a suitably ridge material such as injection molded plastic, or formed using metallic material such as stainless steel (STS) and titanium (Ti).
If desired, one or more intermediate cases may be provided between the first and second cases of one or both of the first and second bodies 200, 205. The first and second bodies 200, 205 are typically sized to receive electronic components necessary to support operation of the mobile terminal 100.
The first body 200 is shown having a camera 121 and audio output unit 152, which is configured as a speaker, positioned relative to the display 151. If desired, the camera 121 may be constructed in such a manner that it can be selectively positioned (e.g., rotated, swiveled, etc.) relative to first body 200.
The function keys 210 are positioned adjacent to a lower side of the display 151. The display 151 is shown implemented as an LCD or OLED. Recall that the display may also be configured as a touchscreen having an underlying touchpad which generates signals responsive to user contact (e.g., finger, stylus, etc.) with the touchscreen.
Second body 205 is shown having a microphone 122 positioned adjacent to keypad 215, and side keys 245, which are one type of a user input unit, positioned along the side of second body 205. Preferably, the side keys 245 may be configured as hot keys, such that the side keys are associated with a particular function of the mobile terminal. An interface unit 170 is shown positioned adjacent to the side keys 245, and a power supply 190 in a form of a battery is located on a lower portion of the second body 205.
FIG. 3 is a rear view of the mobile terminal shown in FIG. 2. FIG. 3 shows the second body 205 having a camera 121, and an associated flash 250 and mirror 255. The flash operates in conjunction with the camera 121 of the second body. The mirror 255 is useful for assisting a user to position camera 121 in a self-portrait mode. The camera 121 of the second body faces a direction which is opposite to a direction faced by camera 121 of the first body 200 (FIG. 2). Each of the cameras 121 of the first and second bodies may have the same or different capabilities.
In an embodiment, the camera of the first body 200 operates with a relatively lower resolution than the camera of the second body 205. Such an arrangement works well during a video conference, for example, in which reverse link bandwidth capabilities may be limited. The relatively higher resolution of the camera of the second body 205 (FIG. 3) is useful for obtaining higher quality pictures for later use or for communicating to others.
The second body 205 also includes an audio output module 152 configured as a speaker, and which is located on an upper side of the second body. If desired, the audio output modules of the first and second bodies 200, 205, may cooperate to provide stereo output. Moreover, either or both of these audio output modules may be configured to operate as a speakerphone.
A broadcast signal receiving antenna 260 is shown located at an upper end of the second body 205. Antenna 260 functions in cooperation with the broadcast receiving module 111 (FIG. 1). If desired, the antenna 260 may be fixed or configured to retract into the second body 205. The rear side of the first body 200 includes slide module 265, which slideably couples with a corresponding slide module located on the front side of the second body 205.
It is understood that the illustrated arrangement of the various components of the first and second bodies 200, 205, may be modified as required or desired. In general, some or all of the components of one body may alternatively be implemented on the other body. In addition, the location and relative positioning of such components are not critical to many embodiments, and as such, the components may be positioned at locations which differ from those shown by the representative figures.
The mobile terminal 100 of FIGS. 1-3 may be configured to operate within a communication system which transmits data via frames or packets, including both wireless and wireline communication systems, and satellite-based communication systems. Such communication systems utilize different air interfaces and/or physical layers.
Examples of such air interfaces utilized by the communication systems include example, frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), and universal mobile telecommunications system (UMTS), the long term evolution (LTE) of the UMTS, and the global system for mobile communications (GSM). By way of non-limiting example only, further description will relate to a CDMA communication system, but such teachings apply equally to other system types.
Referring now to FIG. 4, a CDMA wireless communication system is shown having a plurality of mobile terminals 100, a plurality of base stations 270, base station controllers (BSCs) 275, and a mobile switching center (MSC) 280. The MSC 280 is configured to interface with a conventional public switch telephone network (PSTN) 290. The MSC 280 is also configured to interface with the BSCs 275. The BSCs 275 are coupled to the base stations 270 via backhaul lines. The backhaul lines may be configured in accordance with any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. It is to be understood that the system may include more than two BSCs 275.
Each base station 270 may include one or more sectors, each sector having an omnidirectional antenna or an antenna pointed in a particular direction radially away from the base station 270. Alternatively, each sector may include two antennas for diversity reception. Each base station 270 may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum (e.g., 1.25 MHz, 5 MHz).
The intersection of a sector and frequency assignment may be referred to as a CDMA channel. The base stations 270 may also be referred to as base station transceiver subsystems (BTSs). In some cases, the term “base station” may be used to refer collectively to a BSC 275, and one or more base stations 270. The base stations may also be denoted “cell sites.” Alternatively, individual sectors of a given base station 270 may be referred to as cell sites.
A terrestrial digital multimedia broadcasting (DMB) transmitter 295 is shown broadcasting to portable terminals 100 operating within the system. The broadcast receiving module 111 (FIG. 1) of the portable terminal is typically configured to receive broadcast signals transmitted by the DMB transmitter 295. Similar arrangements may be implemented for other types of broadcast and multicast signaling (as discussed above).
FIG. 4 further depicts several global positioning system (GPS) satellites 300. Such satellites facilitate locating the position of some or all of the portable terminals 100. Two satellites are depicted, but it is understood that useful positioning information may be obtained with greater or fewer satellites. The position-location module 115 (FIG. 1) of the portable terminal 100 is typically configured to cooperate with the satellites 300 to obtain desired position information. It is to be appreciated that other types of position detection technology, (i.e., location technology that may be used in addition to or instead of GPS location technology) may alternatively be implemented. If desired, some or all of the GPS satellites 300 may alternatively or additionally be configured to provide satellite DMB transmissions.
During typical operation of the wireless communication system, the base stations 270 receive sets of reverse-link signals from various mobile terminals 100. The mobile terminals 100 are engaging in calls, messaging, and other communications. Each reverse-link signal received by a given base station 270 is processed within that base station. The resulting data is forwarded to an associated BSC 275. The BSC provides call resource allocation and mobility management functionality including the orchestration of soft handoffs between base stations 270. The BSCs 275 also route the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN interfaces with the MSC 280, and the MSC interfaces with the BSCs 275, which in turn control the base stations 270 to transmit sets of forward-link signals to the mobile terminals 100.
A mobile terminal according to one embodiment of the present invention is capable of performing a road guiding function. And, its example is shown in FIG. 5.
FIG. 5 and FIG. 6 are state diagrams for examples that a mobile terminal is performing a road guiding function.
Referring to FIG. 5, a map having a current location displayed thereon is displayed on the display module 151. In this case, a user is facilitated to find a destination using the displayed map.
And, a mobile terminal capable of performing a road guiding function can be implemented into a navigation system provided to a vehicle. This example is shown in FIG. 6.
According to one embodiment of the present invention, a mobile terminal is able to provide a user with various services associated with location information using its location information or location information on a specific terminal. In this case, it is able to obtain the location information from locations of base stations of a network to which the terminal belongs or location relevant data received from a satellite.
And, it is a matter of course that the vehicle navigation system shown in FIG. 5 or FIG. 6 can be detachably attached to a vehicle. Moreover, the mobile phone type mobile terminal 100 shown in FIG. 2 or FIG. 3 can be detachably attached to a vehicle as well to fully perform functions of the vehicle navigation system.
According to one embodiment of the present invention, a mobile terminal is able to provide a user with various services associated with location information using its location information or location information on a specific terminal. In this case, it is able to obtain the location information from locations of base stations of a network to which the terminal belongs or location relevant data received from a satellite.
In the following description, various services provided in association with the location information are generally named ‘location information providing service’. For clarity and convenience of explanation, a mobile terminal will be divided into a first terminal and a second terminal. Of course, a mobile terminal can include at least two terminals including a first terminal and a second terminal.
Operations of a system for implementing a location information providing service according to the present invention are explained with reference to FIG. 7 as follows.
FIG. 7 is a structural diagram of a system for implementing a location information providing service according to one embodiment of the present invention.
Referring to FIG. 7, a first terminal 100A and a second terminal 100B are able to: (a) indirectly transmit and receive various kinds of information including location information via a server 700; or (b) directly transmit and receive various kinds of information including location information without using the server 700.
According to (a), in implementing a location information providing service, the first or second terminal 100A or 100B is able to use information, which is received from the server 700, on a correspondent terminal. According to (b), in implementing a location information providing service, the first or second terminal 100A or 100B is able to use information which is directly received from the correspondent terminal.
The second terminal 100B is able to generate information based on location on the first terminal 100A using location information (e.g., coordinate information) received from the first terminal 100A. And, the second terminal 100B is able to receive the information based on location generated by the first terminal 100A from the first terminal 100A or the server 700 as well.
In particular, second terminal 100B is able to register the first and second terminals 100A and 100B with the location information providing service to transmit and receive mutual location information using the location information providing service. And, second terminal 100B is able to designate and register the first and second terminals 100A and 100B as terminals for transmitting and receiving mutual location information via the location information providing service.
Various embodiments of a method of providing location information in a mobile terminal according to the present invention are explained as follows.
First of all, location base information in the following description can include various kinds of information, which is generated using location information including coordinate information and the like, associated with a terminal location.
In particular, the information based on location can include at least one selected from the group consisting of administrative (e.g., postal) address information, POI (point of interest) information, setup name information and relative location information. And, it is also understood that the location base information can include the location information, which includes the coordinated information and the like, itself.
The administrative (e.g., postal) address information can hierarchically include a broad-classification area (e.g., country), a first middle-classification area (e.g., state, county, metropolitan area), a second middle-classification area (e.g., city, county, etc.), a first narrow-classification area (neighborhood), a second narrow-classification area (street number, building name), and the like. For instance, the administrative (e.g., postal) address information can be selectively generated from a group ranging from the broad-classification area to the narrow-classification area. In this case, location information (particularly, coordinate information) per the administrative (e.g., postal) address information is beforehand stored in the memory 160 or can be received from outside via the wireless communication unit 110.
The POI information may means a name or special item information, which is set for a specific place. For instance, the POI information can include such a name as ‘xx mart’, ‘xx restaurant’, ‘xx department store’ and the like or such special item information as ‘local Korean restaurant’, ‘Recommended date place’, ‘Weekend visit place’ and the like. In this case, location information (particularly, coordinate information) per the POI information is beforehand stored in the memory 160 or can be received from outside via the wireless communication unit 110.
The setup name information may mean a name or special item information set up for a specific place by a user. For instance, the setup name information can include ‘yesterday meeting place’, ‘first data place’, ‘restaurant for good taste’, ‘company’, ‘house’, ‘school’ and the like. In this case, location information (particularly, coordinate information) per the setup name information is beforehand stored in the memory 160 or can be received from outside via the wireless communication unit 110.
The relative location information may mean information based on such a moving pattern between one point to another point as a moving distance, a moving time, a moving speed, a moving direction and the like or information based on such a relative location with reference to a specific point (e.g., a location of a specific mobile terminal) as a distance, a moving speed, a moving direction and the like. In this case, location information (particularly, coordinate information) on a specific mobile terminal is beforehand stored in the memory 160 or can be received from outside via the wireless communication unit 110.
And, resolution, which will be explained later, may mean a level in accordance with a detailed extent of information based on location that is provided in case that a mobile terminal provides its information based on location to a correspondent terminal. The resolution may mean a level in accordance with a detailed extent of information based on location that will be displayed in displaying information based on location of another terminal. The first terminal is able to set the resolution for each of a plurality of different terminals or in common to at least one different terminal corresponding to a specific condition (e.g., a same group, a predetermined radius range, etc.)
Thus, in FIG. 7, line 1 represents to transmit information including location information from the first terminal 100A to the server 700, line 2 represents to transmit information including location information from the server 700 to the second terminal 100B, line 3 represents to transmit information including location information from the second terminal 100B to the server 700, line 4 represents to transmit information including location information from the server 700 to the first terminal 100A, line 5 represents to transmit information including location information from the first terminal 100A to the second terminal 100B, and line 6 represents to transmit information including location information from the second terminal 100B to the first terminal 100A.
First Embodiment
In the following description, a method of hierarchically generating information based on location in accordance with resolution and a method of providing information based on location according to one embodiment of the present invention are explained with reference to the accompanying drawings. For clarity and convenience of explanation, it is assumed that a mobile terminal described in the following description selectively includes the elements shown in FIG. 1.
First of all, a method of hierarchically generating information based on location in accordance with resolution is explained in detail with reference to FIGS. 8 to 9F. In the following description, a mobile terminal for generating/providing information based on location is named ‘first terminal’ and a different mobile terminal provided with information based on location is named ‘second terminal’.
FIG. 8 is a flowchart of a process for generating and providing information based on location in a first terminal.
Referring to FIG. 8, a first terminal receives location information via the wireless communication unit 110 [S810].
In the receiving step S810, the first terminal is able to receive location information by at least one selected from the group consisting of a broadcasting system, a mobile communication system, a data communication system, a short-range communication system, a GPS and the like.
For instance, the first terminal is able to use the broadcast receiving module 111 in case of the broadcasting system, the mobile communication module 112 in case of the mobile communication system, the wireless internet module 113 in case of the data communication system, the short-range communication module 114 in case of the short-range communication system or the position-location module 115 in case of the GPS.
In this case, the location information is the information that indicates a location of the first terminal and may include coordinate information represented as longitude, latitude, altitude, speed, time and the like.
Moreover, the receiving step S810 may be periodically executed. The receiving step S180 may be executed in case that the location information is updated. The receiving step S810 may be executed in case that a location information providing server or the first terminal makes a request.
Besides, the controller 180 is able to receive a location information reception announcing signal from the wireless communication unit 110 in case of a location information reception. The controller 180 is able to periodically or always monitor a location information reception by the wireless communication unit 110. So, the controller 180 is able to detect that location information is received by the wireless communication unit 110.
Furthermore, the location information received in the receiving step S810 can be stored in the memory 160.
The first terminal sets information based on location using the location information received in the receiving step S810 [S820]. In this case, the first terminal is able to store reference information necessary for generation of information based on location in the memory 160 beforehand or receive the reference information from outside via the wireless communication unit 110. And, an operation of setting the information based on location can be performed by the controller 180 or by the position-location module 115 in accordance with a control signal of the controller 180.
For instance, the first terminal obtains the coordinate information received in the receiving step S810 and then searches coordinate information per the administrative (e.g., postal) address information, the POI information, the setup name information or the relative location information as the reference information necessary for the generation of information based on location for coordinate information matching the obtained coordinate information. The first terminal is able to set the information based on location to the administrative (e.g., postal) address information, POI information, setup name information or relative location information corresponding to the coordinate information matching the obtained coordinate information.
In the setting step S820, the first terminal is able to hierarchically set the information based on location to correspond to the resolution set for the second terminal. It is understood that there may exist a plurality of second terminal. In this case, the set resolution and the set information based on location can be stored in the memory 160. Meanwhile, if a resolution level is set to a highest value for the second terminal, the first terminal is able to set the information based on location to the coordinate information itself.
In the following description, the resolution setting by the first terminal is explained in detail.
First of all, a condition for the resolution setting can be selected by a user or can be randomly selected by the first terminal. For convenience and clarity of explanation, it is assumed that the resolution can be set to a level ranging from a first level to a tenth level. And, it is also assumed that the information based on location gets more detailed toward the tenth level from the first level. Alternatively, it is able to set the information based on location to get more detailed toward the first level from the tenth level. And, the resolution level can be modified by a user's manipulation or can be frequently modified in accordance with a location of the second terminal.
The first terminal is able to set the resolution for the second terminal in accordance with a location association of the second terminal with itself.
For instance, the first terminal is able to set the resolution to a higher level if the location association of the second terminal with the first terminal increases (e.g., the classification of the matched administrative area gets smaller). In particular, if ‘country and state’ matches rather than ‘country’ only, it can be said that the location association is higher. It is understood that the resolution can be set to a higher level if the location association decreases to the contrary.
The resolution setting in accordance with the location association with reference to the administrative (e.g., postal) address information can be explained in more detail with reference to FIGS. 9A to 9F. For clarity and convenience of explanation, it is assumed that the resolution is set to a higher level if the location association becomes higher.
FIGS. 9A to 9F are diagrams of a screen for setting resolution in accordance with location correlation according to one embodiment of the present invention.
Referring to FIG. 9A, if the second terminal 100B is located in a country different from a country where the first terminal 100A is located, the first terminal 100A is able to set a first level having a lowest detail extent of the provided information based on location.
Referring to FIG. 9B, if the second terminal 100B is located at ‘state’ ‘county’ or ‘metropolitan area’ different from that of the first terminal 100A in the same country of the first terminal 100A, the first terminal 100A is able to set a second level having a second lowest detail extent of the provided information based on location.
Referring to FIG. 9C, if the second terminal 100B is located at a region (i.e., zip code) different from that of the first terminal 100A in the same country/state of the first terminal 100A, the first terminal 100A is able to set a third level having a third lowest detail extent of the provided information based on location.
Referring to FIG. 9D, if the second terminal 100B is located at a city different from that of the first terminal 100A in the same country/state/zip code of the first terminal 100A, the first terminal 100A is able to set a fourth level having a fourth lowest detail extent of the provided information based on location.
Referring to FIG. 9E, if the second terminal 100B has detailed address information (e.g., building name) different from that of the first terminal 100A in the same country/state/city/region (i.e., zip code) of the first terminal 100A, the first terminal 100A is able to set a fifth level having a fifth lowest detail extent of the provided information based on location.
Referring to FIG. 9F, if the second terminal 100B has the same country/state/city/region (i.e., zip code)/detailed address information of the first terminal 100A, the first terminal 100A is able to set a tenth level having a highest detail extent of the provided information based on location.
In addition, the first terminal 100A is able to set the resolution in accordance with location association with reference to a distance from the second terminal 100B (option not shown in the drawing).
For instance, if the second terminal 100B gets closer to the first terminal 100A, the first terminal 100A is able to set the resolution enabling the information based on location provided to the second terminal 100B to have a more detailed level. On the contrary, if the second terminal 100B gets farther from the first terminal 100A, the first terminal 100A is able to set the resolution enabling the provided information based on location to have a more detailed level.
The first terminal 100A is able to set the resolution for the second terminal 100B in accordance with a intimacy/permission level (explained later) set by the second terminal 100B. In this case, the intimacy/permission level is automatically set by considering an extent of call/message transmission/reception between the first and second terminal 100Bs or can be directly specified by a user.
For instance, if the intimacy/permission level set for the second terminal 100B increases, the first terminal 100A is able to set the resolution enabling the information based on location provided to the second terminal 100B to have a more detailed level. On the contrary, if the intimacy/permission level decreases, the first terminal 100A is able to set the resolution enabling the provided information based on location to have a more detailed level.
The first terminal 100A is able to set a resolution for the second terminal 100B to a resolution directly inputted by a user. Of course, in case that at least one or more second terminal 100Bs are managed as a group, the first terminal 100A is able to set the resolution for the group.
In the following description, a process for a first terminal 100A to generate information based on location hierarchically in accordance with a resolution set for a second terminal 100B is explained in detail.
In this case, the hierarchical generation of the information based on location may mean that the generation is carried out by adjusting an extent of provision (in case of transmitting information based on location to the second terminal 100B) or display (in case of receiving information based on location from the second terminal 100B) of the information based on location to correspond to the resolution.
In the following description, the information based on location is limited to the administrative (e.g., postal) address information. In the following description, geographic entities common in U.S.A. are referenced. However, one skilled in the art would know that geographic entities of other nations may be, singly or in combination. For convenience and clarity of explanation, it is assumed that more detailed administrative (e.g., postal) address information is generated if a level of resolution increases. So, it is able to hierarchically generate the administrative (e.g., postal) address information in accordance with the level of resolution.
For instance, in case that overall administrative (e.g., postal) address information that can be generated using location information on the first terminal 100A is ‘10 #1004, Apartment-A, 100 A Road Suite 100 East, Falls Church, Va. 1000, U.S.A.’, information based on location generated to correspond to the resolution of the second terminal 100B can be represented as Table 1.

Meanwhile, in case of receiving the information based on location on the second terminal 100B, the first terminal 100A is able to hierarchically generate the information based on location of the second terminal 100B, which will be displayed to correspond to the resolution set for the second terminal 100B, in accordance with Table 1. for instance, if the information based on location on the second terminal 100B is ‘Falls Church, Va. 1000, U.S.A.’ and if a third level of resolution is set for the second terminal 100B, the first terminal 100A is able to generate ‘Virginia, U.S.A.’ as the information based on location, which will be displayed, on the second terminal 100B.
Alternatively, for instance, a timing point (with reference to a distance from the first terminal 100A to the second terminal 100B) of providing information based on location in accordance with resolution of the second terminal 100B and an update period can be represented as Table 2. The per-resolution distance and the update period can be individually set.

As shown in Table 1 and Table 2, it is assumed that one of the first to tenth levels can be selectively set for a single second terminal 100B. And, it is also assumed that there exits ten second terminal 100Bs corresponding to the first to tenth levels, respectively.
Meanwhile, the first terminal 100A transmits the information based on location hierarchically generated by the controller 180 or the position-location module 115 to the second terminal 100B via the wireless communication unit 110 [S830].
The first terminal 100A, as explained in the receiving step S810, is able to transmit the information based on location to the second terminal 100B using the broadcast receiving module 111 in case of the broadcast system, the mobile communication module 112 in case of the mobile communication system, the wireless internet module 113 in case of the data communication system, the short-range communication module 114 in case of the short-range communication system or the position-location module 115 in case of the GPS.
And, the transmitting step S830 can be executed in case of making a registration request of the location information providing service to the second terminal 100B. This will be explained in detail as follows.
Moreover, the transmitting step S830 can be executed in case that the second terminal 100B accesses the location information providing service. This will be explained in detail as follows.
In the following description, a method of providing location information in case of registration with a location information providing service is explained with reference to FIGS. 10 to 14D. In this case, the registration may mean the registration with the location information providing service or the registration as a terminal for transmitting/receiving mutual location information via the location information providing service among the beforehand registered terminals.
FIG. 10 is a first flowchart of a process for registering a mobile terminal with a location information providing service according to one embodiment of the present invention.
Referring to FIG. 10, the first terminal 100A stores identification information on the first terminal 100A [S1010].
In the storing step S1010, the first terminal 100A stores its identification information in the memory 160. Alternatively or in addition, the first terminal 100A is registered with a server and then stores its identification information in the server.
In this case, the identification information is information for identifying the first terminal 100A or a user of the first terminal 100A in using a location information providing service. And, the identification information can include a terminal serial number, an international mobile equipment identity (IMEI) number (or another mobile equipment ID), a user ID and password subscribed in a location information providing service, a name registered with a location information providing service, a terminal phone number, a subscribed e-mail address, a subscriber homepage address and the like. So, the server is able to authenticate location information providing service use authority of the first terminal 100A using the identification information on the first terminal 100A. A different terminal is able to identify that the first terminal 100A is the terminal having made the request for the location information providing service to the different terminal using the identification information on the first terminal 100A which is received from the first terminal 100A or the server.
The first terminal 100A makes a request for a registration with a location information providing service to the second terminal 100B via the wireless communication unit 110 [S1020]. For instance, in case of using the mobile communication terminal 112, the registration request can be carried out using such a messaging service as SMS (short message service), MMS (multimedia messaging service) and the like. It is understood that the requesting step S1020 can be carried out using every system capable of transmitting/receiving data between terminals as well as the aforesaid messaging service.
The first terminal 100A carries out the requesting step S1020 via the server or can directly perform the requesting step S1020 on the second terminal 100B without using the server. In some cases, even if the registration is not requested by the first terminal 100A, it is able to make a request for registration with a location information providing service to at least one terminal randomly selected by the server. In this case, a registration requesting procedure by the first terminal 100A may be unnecessary.
In the requesting step S1020, the identification information or the information based on location on the first terminal 100A can be transmitted to the second terminal 100B. This is to inform the second terminal 100B of the terminal having made the request for the location information providing service to the second terminal 100B and a location thereof.
Prior to the execution of the requesting step S1020, the first terminal 100A is able to hierarchically generate information based on location information to be transmitted in the requesting step S1020, in accordance with a resolution set for the second terminal 100B as a registration request target.
Alternatively, prior to the execution of the requesting step S1020, the first terminal 100A is able to specify a type and provision extent of the identification information or the information based on location which will be transmitted in the requesting step S1020 among the overall identification information or the overall information based on location relevant to the first terminal 100A.
The provision extent of the information based on location may differ in accordance with the intimacy/permission level set for the second terminal 100B. For instance, in case that the intimacy/permission level is high, it may be able to transmit coordinate information (basic information for generating the aforesaid overall location information) as it is. In case that the intimacy/permission level is low, it is able to transmit distance information (e.g., the first terminal 100A is located within the radius 5 km of the second terminal 100B) only.
If the registration with the location information providing service is approved by the second terminal 100B, the first terminal 100A is registered as a target terminal of the location information providing service [S1030, S1040].
The first terminal 100A can be provided with feedback whether or not the registration with the location information providing service was approved by the second terminal 100B by the server or the second terminal 100B via the wireless communication unit 110. If the registration with the location information providing service was approved by the second terminal 100B, the first terminal 100A, the second terminal 100B or the server can register the first terminal 100A and second terminal 100B as mutual target terminals of the location information providing service. The location information providing service target terminal information is stored in the memory 160 of each of the first and second terminal 100Bs or the server and then managed.
FIG. 11 is a second flowchart of a process for registering a mobile terminal with a location information providing service according to one embodiment of the present invention.
Referring to FIG. 11, the second terminal 100B receives a request for registration with a location information providing service from the first terminal 100A or the server via the wireless communication unit 110 [S1110].
Subsequently, the second terminal 100B received identification information or location information on the first terminal 100A from the first terminal 100A or the server [S1120].
The requesting and receiving steps S1110 and S1120 can be carried out using such a messaging service as SMS, MMS and the like. It is understood that the requesting and receiving steps S1110 and S1120 can be carried out using every system capable of transmitting/receiving data between terminals as well as the messaging service.
If the registration with the location information providing service is approved by the second terminal 100B, the second terminal 100B is registered as a target terminal of the location information providing service of the first terminal 100A [S1130, S1140]. In this case, the first terminal 100A, the second terminal 100B or the server can register the first and second terminal 100Bs as mutual target terminals of the location information providing service.
FIG. 12 is a state diagram of a screen on which a process for registering a mobile terminal of one embodiment of the present invention with a location information providing service according to a first embodiment of the present invention is displayed.
Referring to FIG. 12, the first terminal 100A is able to select at least one target terminal to make a request for a registration with a location information providing service, in accordance with a selection made by a user. In this case, the user may directly input a phone number of the target terminal or may select the target terminal by searching phone numbers or names stored in a phonebook or names set for the phone numbers. The user is able to select at least one or more terminals for which resolution levels above/below predetermined levels are set, respectively.
In FIG. 12, the first terminal 100A makes the registration with the location information providing service to terminals corresponding to phone number ‘011-111-1111’, name ‘Chulsoo’ and name ‘Younghee’, respectively.
FIGS. 13A to 13D are state diagram of a screen on which a process for registering a mobile terminal of one embodiment of the present invention with a location information providing service according to a second embodiment of the present invention is displayed.
Referring to FIG. 13A, the first terminal 100A displays a sentence that queries whether a request for a registration with a location information providing service will be made or not on a screen [a].
If the request (‘yes’) is selected in the state [a], the first terminal 100A displays a selection condition list of a terminal (hereinafter named ‘registration request terminal’) to which the registration with the location information providing service will be made [b].
The selection condition list displayed in the state [b] can include a distance, a place, a phonebook and distance/place/phonebook. Also, a distance/phonebook option (not shown) may be selected.
In case that the distance is selected from the selection condition list, the first terminal 100A is able to display an image shown in FIG. 13B. Referring to FIG. 13B, the first terminal 100A is able to select terminals located within a predetermined radius from the first terminal 100A as registration request terminals. In this case, the predetermined distance is directly inputted by a user using a numeral key or a direction key or can be inputted by being selected from a list including settable radiuses.
If the place is selected from the selection condition list, the first terminal 100A is able to display an image shown in FIG. 13C. Referring to FIG. 13C, the first terminal 100A is able to select terminals located in a specific place as registration request terminals. In this case, a user is able to directly input a specific place (e.g., ‘A Station exit #7’) via an input window or can input the specific place by selecting it from a place list.

For instance, if at least five or more correspondent terminals are located within a radius 5 km centering on A station, the controller 180 automatically generates a map on which the at least five terminals are displayed. The controller 180 then displays the generated map on the display 151.
According to one embodiment of the present invention, a reduced scale of a map to be seen can be determined in accordance with a resolution. The resolution can be set different in accordance with an area. For instance, the resolution can be differentially set based on user's activity. For instance, a resolution level for an area having a relatively high activity time of user is set to 1, while a resolution level for an area having a relatively low activity time of user is set to 1.
It is able to determine the resolution based on information opening extent set per a terminal. The information opening extent can be determined based on intimacy/permission level with a correspondent terminal. The intimacy/permission level can be set per a correspondent terminal. If a correspondent terminal is managed as a group, the intimacy/permission level can be determined per the corresponding group. Namely, the resolution can be determined in accordance with the intimacy/permission level. For instance, if intimacy/permission level is 10, a resolution level is set to 1. If intimacy/permission level is 5, a resolution level is set to 3.
FIG. 39 is a diagram of a screen to depict that a reduced scale varies in accordance with a resolution in a mobile terminal according to one embodiment of the present invention.
Referring to (a) of FIG. 39, shown is a map having a large reduced scale due to a relatively high resolution level. Referring to (b) of FIG. 39, shown is a map having a small reduced scale due to a relatively low resolution level. The reduced scale is shown on a right upper end of a screen. A reduced scale of 1 to 20,000 is shown in (a) of FIG. 39 and a reduced scale of 1 to 40,000 is shown in (b) of FIG. 39. The reduced scale can be varied by a key manipulation of the user input unit 130. For instance, a reduced scale of a map can be varied using a scroll key. Yet, a reduced scale may not be varied by a key manipulation of the user input unit 130 unless a resolution is changed.
Meanwhile, the mobile terminal 100 according to one embodiment of the present invention selects a specific one of correspondent terminals and is then able to perform a specific function associated with the selected terminal [S3630, S3640]. Namely, if a specific terminal is selected from correspondent terminals, the controller 180 is able to perform a specific function associated with the selected terminal.
Meanwhile, the mobile terminal 100 may include a touchscreen. In this case, a selection for a specific terminal can be carried out by a touch input. Thus, a method of selecting a specific terminal via a touch input is shown in FIG. 52.
A screen, on which a correspondent terminal is represented as an icon type on a map, is shown in (a) of FIG. 40A. The icon represents identification information for identifying a prescribed correspondent party. It is able to know where a correspondent party is located via the icon displayed on the map. The mobile terminal 100 is able to selectively display a correspondent terminal that has accessed a location information providing service only.
A user of the mobile terminal 100 groups correspondent terminals and is then able to manage the grouped correspondent terminals. In this case, an icon corresponding to the correspondent terminal belonging to a specific group can be displayed on the map only. On the screen shown in the drawing, a correspondent terminal belonging to a group ‘friend’ is displayed only. In this case, a user is able to confirm a correspondent terminal belonging to another group by touching a direction key 4001 of a window representing a group name.
If a user touches a direction key 403 represented on the map, the controller 180 is able to shift a center of the displayed map. Through the shift of the map, it is able to confirm a correspondent terminal located at another area.
A user is able to enlarge/reduce the displayed map by touching ‘+’/‘−’ displayed on a lower end of the screen. Of course, the displayed map may not be enlarged or reduced unless a resolution of the map varies.
Besides, a specific terminal can be selected from correspondent terminals displayed on the map by a user's touch input.
An example of selecting a specific terminal by a touch input is shown in (b) of FIG. 40. A user touches a screen having a map represented thereon and then draws a looped curve 4005, thereby selecting a specific terminal within the looped curve 4005. In particular, if the looped curve 4005 is drawn on the map by a user's touch input, a specific terminal existing within the looped curve 4005 is selected. In this case, a single specific terminal or a plurality of specific terminals may be selected.
The controller 180 is able to carry out a specific function associated with the selected specific terminal. For instance, while the specific terminal is selected, the controller enters ‘option’ to carry out a specific function associated with the selected specific terminal. And, there can exist various kinds of specific functions.
As examples of the specific functions, there are a voice call, a video communication, and a message or data transmission using SMS (short message service), MMS (multimedia message service), e-mail, IM (instant message), Bluetooth or the like. As examples of the specific functions, there exist an information display of an area where the selected specific terminal is located, a road guide to the selected terminal, etc.
Meanwhile, the controller 180 recognizes a specific character or symbol written on the screen and then carries out a specific function corresponding to the written specific character or symbol. This is shown in FIG. 41.
Referring to FIG. 41, a specific function can be performed in a manner of inputting a specific character or letter by handwriting to a screen on which a looped curve 4005 is drawn for a selection of a specific terminal. For instance, if ‘S’ is inputted by handwriting, the mobile terminal is able to send a message to the selected specific terminal using SMS (short message service). If ‘C’ is inputted by handwriting, the mobile terminal 100 is able to transmit a call signal to the selected specific terminal [not shown in the drawing]. In this case, the controller 180 is able to recognize user's handwriting as a signal for performing a specific function.
According to one embodiment of the present invention, the mobile terminal 100 is able to set a specific character to match a specific function. For instance, ‘E’ is set to match a use of e-mail. And, ‘I’ is set to match a use of IM (instant message).
Thus, if a specific character matches a specific function, a user is able to perform data transmission via e-mail in a manner of inputting ‘E’ to the looped curve 4005 by handwriting [not shown in the drawing]. In particular, if ‘E’ is inputted to the looped curve 4005 by user's handwriting, the controller 180 is able to carry out data transmission via e-mail.
A specific function connected to the selected terminal can be carried out in a following manner. For instance, the mobile terminal 100 is able to perform voice or video communication by transmitting a call signal to the selected specific terminal.
The mobile terminal 100 is able to send a message or data to the selected specific terminal as a receiving terminal using SMS (short message service), MMS (multimedia message service), e-mail or the like.
The mobile terminal 100 is able to perform chatting with a user of a selected terminal using IM (instant message). In particular, in case that a plurality of specific terminals are selected, the mobile terminal 100 is able to perform multi-user chatting.
In case that the selected specific terminal is located in a short distance from the mobile terminal 100, the mobile terminal 100 is able to perform short-range communication using Bluetooth.
The mobile terminal is able to announce information on an area where the selected specific terminal is located. For instance, if a selected terminal is located in a foreign country, the mobile terminal 100 is able to inform the selected terminal of weather, exchange rate, composite price index of stocks, local traffic information and local news of the corresponding country, etc. via sub-menus.
Meanwhile, the mobile terminal 100 according to one embodiment of the present invention is able to perform the specific functions by considering characteristics of the selected specific terminal.
For instance, in case of sending a message to a selected specific terminal using SMS (short message service), MMS (multimedia message service), e-mail, IM (instant message) or the like, the mobile terminal 100 is able to send the message by translating the written message into a language of a country where the selected specific terminal is located. This example is shown in FIG. 42.
Referring to FIG. 42, message contents written in Korean can be translated into a language of a country where a selected terminal is located. The mobile terminal 100 is able to carry out the translating work using an automatic translation program. If a selected terminal is located in U.S.A., the mobile terminal 100 automatically translates contents of a message written in Korean into English and then sends it to the selected terminal.
Meanwhile, a function supported by the mobile terminal 100 may differ from that supported by a selected terminal. So, the mobile terminal 100 is able to perform a specific function by considering compatibility with the selected terminal. For instance, when a user attempts to send a message, if special characters, font and the like, which can be supported by the mobile terminal 100, are transmitted, an outgoing is successfully performed. Yet, if a message receiving side (i.e., selected terminal) fails to support the same function, the message is seen broken. So, a correspondent user (i.e., selected terminal user) is unable to confirm the message contents correctly. Assuming that the selected terminal is provided with a viewer for opening to view an image file, if a message is sent to a receiving terminal by being converted to an image, the selected terminal is able to correctly recognize contents of the message.
According to one embodiment of the present invention, in case of attempting to convert an extract message to an image, it is checked whether specific symbols are contained in the extracted message to decide whether the message will be converted to an image. The specific symbols may include non-English characters (e.g., Japanese characters: Hirakana, Katakana), symbols, figure images, fonts, special characters, symbols drawn by user's handwriting (if a mobile terminal includes a touchpad), etc. And, the symbols drawn by user's handwriting may include characters, numerals, signs, drawings and the like.
The presence or non-presence of the specific symbols included in the extracted message can be checked by user's eyes in direct. Alternatively, the presence or non-presence of the specific symbols included in the extracted message can be checked by the mobile terminal 100 and its result can be notified to a user.
When the mobile terminal 100 checks the specific symbol, the specific symbol can use a symbol defaulted in the mobile terminal 100 or a symbol set by a user. For instance, a special symbol may be defaulted as a specific symbol in the mobile terminal 100. In this case, if a special symbol is contained in an extracted message, the controller 180 is able to display a popup window for announcing that a specific symbol is contained. And, a user is able to set non-English characters (e.g., Japanese characters: Hirakana, Katakana) to specific letters. In this case, if the set non-English letters are contained in the extracted message, the controller 180 is able to display a popup window for announcing that specific symbols are contained.
The method of announcing that specific symbols are contained via the popup window is just exemplary, which does not put limitation on various implementations of the present invention. For instance, it is able to announce that specific symbols are contained in an extracted message via audio or vibration output.
In case that specific symbols are contained in an extracted message, it is able to convert the extracted message to an image. In this case, the extracted message can be made to contain contents of message only. For instance, it is able to convert a message to an image by extracting contents of the message only without containing an indicator and the like displayed on a display module. In this case, a message part converted to the image includes a message part viewed by a manipulation of a scroll key or a navigation key as well as a part currently displayed on a screen.
Subsequently, the image is transmitted. In this case, the controller 180 is able to transmit the image together with the message to send originally. The image transmission can be carried out using MMS or e-mail.
FIG. 43 is a diagram of a screen to depict a method of transmitting an image converted from a message in a mobile terminal according to one embodiment of the present invention.
Referring to (a) of FIG. 43, shown is an example that a message containing a specific non-English letter and a symbol (umbrella) is hand written. In this case, the non-English letter and/or the symbol may be recognized as specific symbols. If the ‘OK’ key displayed on a screen is inputted, the controller 180 analyzes whether a specific symbol is contained in the message. In particular, if ‘OK’ is selected from the screen shown in the drawing, an image shown in (b) of FIG. 43 is displayed.
Referring to (b) of FIG. 43, a popup window 4301 for announcing that a specific symbol is contained in the message is displayed. If ‘OK’ is selected from the screen shown in the drawing, the written message is converted to an image file. The image file is then transmitted [(c) of FIG. 43]. In this case, it is able to send an original message together with the image. The image file transmission can be carried out using MMS.
Meanwhile, if a selected terminal fails to recognize the message containing the symbols (including characters, numerals, figures, etc.) written by handwriting, the mobile terminal 100 converts the message to an image and then transmits the image to the selected terminal.
FIG. 44 is a diagram of a screen to depict a method of transmitting an image converted from a message written by user's handwriting in a mobile terminal according to one embodiment of the present invention.
Referring to (a) of FIG. 44, shown is an example of a message written by handwriting. In this case, symbols written by handwriting can be recognized as specific symbols. If ‘OK’ key displayed on a screen is inputted, the controller 180 can analyze whether a specific symbol is contained in the message. In particular, if ‘OK’ is selected from the screen shown in the drawing, an image shown in (b) of FIG. 44 is displayed.
Referring to (b) of FIG. 44, a popup window 4401 for announcing that a specific symbol is contained in the message is displayed.

Referring to FIG. 54, the mobile terminal 100 is able to receive location information via the wireless communication unit 110 [S5410]. In this case, the location information can be received by real time or with a prescribed time interval.
The controller 180 is able to store a current location and a current time in the memory 160 with a prescribed time interval based on the received location information [S5420]. The controller 180 generates a moving trace for representing time information using information containing the current location and the current time with the prescribed time interval and then displays the generated moving trace on the display 151 [S5430].
FIG. 55 is a diagram of a screen on which an example of generating a moving history of a mobile terminal according to one embodiment of the present invention is displayed.
Referring to FIG. 55, a moving trace of a mobile terminal is displayed on a map displayed on a screen. And, time information on the mobile terminal remaining on a specific place is displayed on the screen on which the moving trace is displayed. And, the moving trace is represented to be discriminated in accordance with a moving speed. In particular, the controller 180 is able to represent the moving trace to be discriminated in accordance with the moving speed. In this case, if the moving speed is greater than a specific speed, it can be indicated by a solid line. If the moving speed is smaller than the specific speed, it can be indicated by a dotted line. Meanwhile, the controller 180 grades the moving speed and then displays the moving speed to be discriminated via a display color of the moving trace for each corresponding grade [not shown in the drawing].
The controller 180 is able to generate a moving trace by having the moving trace contain a specific record as well as time information. In this case, the specific record may be relevant to a specific time. For instance, in case that the mobile terminal 100 plays a specific music file for a specific time, it is able to display a record 5501 about music file playback on the moving trace. And, a specific location having time information displayed on the moving trace can be represented as specific words or a specific image. Through the specific words or the specific image, a user can be reminded of what he had done at the corresponding place on the corresponding time. A specific image 5503 is displayed on the screen shown in the drawing.
