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. 
     As used herein, the terms ‘module’, ‘unit’ and ‘part’ are used for elements in order to facilitate the disclosure only. Therefore, significant meanings or roles are not given to the suffixes themselves and it is understood that the ‘module’, ‘unit’ and ‘part’ can be used together or interchangeably. 
       FIG. 1  is a block diagram of terminal  100  in accordance with an embodiment of the present invention. The terminal  100  may be implemented as a variety of terminal types. 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 and for convenience and conciseness of the following description, the present invention is illustrated as a mobile phone. It is not intended to limit the scope of the present invention. The teachings of the present invention apply equally to other types of terminals. 
       FIG. 1  shows the 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 the terminal  100  having a wireless communication unit  110  configured with various components. The broadcast receiving module  111  receives a broadcast signal and broadcast associated information from an external broadcast managing entity via a broadcast channel. 
     The broadcast channel may include a satellite channel or a terrestrial channel. The broadcast managing entity may be a system which transmits a broadcast signal or broadcast associated information. 
     Examples of broadcast associated information include information associated with a broadcast channel, a broadcast program, or a broadcast service provider. For example, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) or electronic service guide (ESG) of digital video broadcast-handheld (DVB-H). 
     The broadcast receiving module  111  may receive broadcast signals transmitted from various types of broadcast systems. By nonlimiting 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). 
     The broadcast receiving module  111  may also receive multicast signals. Data received by the broadcast receiving module  111  may be stored in a suitable device, such as the memory  160 . 
     The mobile communication module  112  transmits and receives wireless signals to and from one or more network entities, such as a base station or a Node-B. The wireless signals may represent audio, video, multimedia, control signaling, or data. 
     The wireless Internet module  113  provides Internet access for the terminal  100 . The wireless Internet module  113  may be internally or externally coupled to the terminal  100 . 
     The short-range communication module  114  facilitates short-range communications. Suitable technologies for implementing the short-range communications module  114  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™. 
     The position-location module  115  identifies and obtains the location of the terminal  100 . The position-location module  115  may be implemented using global positioning system (GPS) components which cooperate with associated satellites and network components. 
     The audio/video (A/V) input unit  120  provides audio or video signal inputs to the terminal  100 . The A/V input unit  120  may include 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 terminal  100  is in a particular mode, such as a phone call mode, a recording mode, or a voice recognition mode. The audio signal is processed and converted into digital data. The terminal  100  and A/V input unit  120  may include 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 the memory  160 , utilized by the output unit  150 , or transmitted via one or more modules of communication unit  110 . The terminal  100  may include two or more microphones  122  or cameras  121 . 
     The user input unit  130  generates input data in response to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad, a jog wheel, and a jog switch. 
     The sensing unit  140  provides status measurements for various aspects of the terminal  100 . For example, the sensing unit may detect an open and close state of the terminal  100 , relative positioning of components of the terminal, a change of position of the terminal, a change of position of a component of the terminal, a presence or absence of user contact with the terminal, orientation of the terminal, or acceleration or deceleration of the terminal. The sensing unit  140  may also sense the presence or absence of power provided by the power supply  190  and the presence or absence of a connection between the interface unit  170  and an external device. 
     The interface unit  170  may be implemented to connect the terminal with an external device. External devices include wired and wireless headphones, external chargers, power supplies, storage devices configured to store data, or microphones. The interface unit  170  may be configured using a wired and wireless data port, a memory card socket, audio input and output ports (I/O), or video I/O ports. 
     The interface unit  170  may act as a passage for supplying the mobile terminal  100  with a power from the cradle or delivering various command signals input from the cradle if the mobile terminal  110  is connected to an external cradle. Each of the various command signals input from the cradle or the power may operate as a signal enabling the mobile terminal  100  to recognize that it is correctly loaded in the cradle. 
     The output unit  150  outputs information associated with the terminal  100 . The display  151  is typically implemented to display information associated with the terminal  100 . For example, the display  151  may provide a graphical user interface which includes information associated with a phone call if the terminal is operating in a phone call mode. The display  151  may display images which are associated with various modes, such as a video call mode or a photographing mode. 
     The display  151  may be configured as a touch screen working in cooperation with the input unit  130 , in one embodiment of the present invention. This configuration allows the display  151  to function both as an output device and an input device. 
     The display  151  may be implemented using known display technologies such as a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display, or a three-dimensional display. The terminal  100  may include one or more displays  151 . An example of a two-display embodiment is one in which one display  151  is configured as an internal display which is viewable when the terminal  100  is in an opened position and a second display configured as an external display which is viewable in both the open and closed positions. 
     The touchscreen can be configured to detect a touch input pressure as well as a touch input position and size. 
     Meanwhile, a proximity sensor (not shown) may be provided within or around the touchscreen. The proximity sensor detects an object approaching a prescribed detecting surface or a presence or non-presence of an object existing around itself using an electromagnetic power or infrared rays without mechanical contact. 
     Example of the operational principle of the proximity sensor are explained as follows. First, an oscillation amplitude of the oscillation circuit attenuates or stops if an object approaches a sensor detecting surface while an oscillation circuit oscillates a sine radio frequency. This change is converted to an electric signal to detect a presence or non-presence of the object. Therefore, a proximity switch may detect any non-metallic object without interference. 
     Additionally, an electrostatic may be configured to detect the proximity of a pointer via an electric field change attributed to the proximity of the pointer. 
     The sensor may detect a position of the pointer and a distance between the pointer and the touchscreen if the pointer is placed in the vicinity of the touchscreen without being actually contacted with the touchscreen. For clarity and convenience of explanation, an action for enabling the pointer approaching the touchscreen to be recognized as placed on the touchscreen is referred to as a ‘proximity touch’ and an action of enabling the pointer to actually come into contact with the touchscreen is referred to as a ‘contact touch’. Additionally, a position at which the proximity touch is made to the touchscreen using the pointer is referred to as the position of the pointer vertically corresponding to the touchscreen when the pointer makes the proximity touch. 
       FIG. 1  further shows the output unit  150  having an audio output module  152 . The audio output module  152  may be implemented using one or more speakers, buzzers, or other audio producing devices. 
     The audio output module  152  functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, or a broadcast reception mode. The audio output module  152  outputs audio relating to a particular function, such as a call notification, a message notification, or a error notification. 
     The output unit  150  is further shown having a vibration module  153 , which may be used to identify the occurrence of an event associated with the terminal  100 . An example an output of vibration module  153  includes a vibration as a notification to a user. 
     The vibration module  153  may vibrate when the terminal  100  receives a call or message. Vibration may also be provided by the vibration module  153  in response to receiving user input at the terminal  100 , thereby providing a tactile feedback mechanism. It is understood that the various outputs provided by the components of output unit  150  may be performed separately or performed using any combination of the components. 
     The memory  160  may store various types of data to support the processing, control, or storage requirements of the terminal  100 . Examples of such data include program instructions for applications operating on the terminal, contact data, phonebook data, messages, pictures, or video. 
     The memory  160  shown in  FIG. 1  may be implemented using any type of volatile and non-volatile memory or storage devices. Such devices may include 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  controls the overall operations of the terminal  100 . For example, the controller  180  performs the control and processing associated with voice calls, data communications, video calls, camera operations, and recording operations. 
     The controller  180  may include a multimedia module  181  which provides multimedia playback. The multimedia module  181  may be configured as part of the controller  180  or may be implemented as a separate component. 
     Moreover, the controller  180  is able to perform a pattern recognizing process for recognizing a writing input and a picture drawing input carried out on the touchscreen as characters or images. 
     The power supply  190  provides power to the various components of the terminal  100 . The power provided may be internal power or external power. 
     Various embodiments described herein may be implemented in a computer-readable medium using computer software. The various embodiments may also be implemented in hardware. 
     A hardware implementation may be implemented using 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, or other electronic units designed to perform the functions described herein. Some embodiments are implemented by controller  180 . 
     A software implementation of 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 code may be implemented with a software application written in any suitable programming language and may be stored in the memory  160  for execution by the controller  180  or a processor. 
     The terminal  100  may be implemented in a variety of different configurations. Examples of such configurations include folder-type, slide-type, bar-type, rotational-type, and swing-type. 
     For clarity, further disclosure will primarily relate to a slide-type terminal  100 . However such teachings apply equally to other types of terminals  100 .  FIG. 2  is a perspective view of a front side of a terminal  100  according to an embodiment of the present invention. As shown in  FIG. 2 , the terminal  100  is shown having a first body  200  configured to slideably cooperate with a second body  205 . 
     The first body  200  slides relative to second body  205  between open and closed positions. The first body  200  is positioned over the second body  250  in the closed position such that the keypad  215  is substantially or completely obscured by the first body  200 . The user may access the keypad  215 , the display  151 , and function keys  210  in the open position. The function keys  210  may be configured for a user to enter commands such as start, stop, or scroll. 
     The user input unit  130  is implemented using the function keys  210  and keypad  215 . The function keys  210  are associated with the first body  200  and the keypad  215  is associated with the second body  205 . The keypad  215  includes various keys such as numbers, characters, and symbols, to enable a user to place a call, prepare a text or multimedia message, and operate the terminal. 
     The terminal  100  is operable in either a standby mode or an active call mode. Typically, the terminal  100  functions in the standby mode when in the closed position and in the active mode when in the open position. The mode configuration may be changed as required or desired by the user. 
     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 respective first  220 ,  230  and second  225 ,  235  cases may be formed from a suitably ridge material such, as injection molded plastic, or formed using metallic material, such as stainless steel (STS) and titanium (Ti). 
     One or more intermediate cases may be provided between the first case  220  and second case  225  of the first body  200  or between the first case  230  and second case  235  of the second body  205 . The first body  200  and the second body  205  may be sized to house electronic components necessary to support operation of the terminal  100 . 
     The first body  200  is shown having a camera  121  and audio output module  152 . The camera  121  may be selectively positioned such that it may rotate or swivel relative to the 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. The display  151  may also be configured as a touchscreen having an underlying touchpad which generates signals responsive to user contact with the touchscreen. 
     The second body  205  is shown having a microphone  122  positioned adjacent to the keypad  215  and side keys  245  positioned along the side. The side keys  245  may be configured as hot keys, such that the side keys are associated with a particular function of the terminal  100 . 
     An interface unit  170  is shown positioned adjacent to the side keys  245 . 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 terminal  100  shown in  FIG. 2 . As shown in  FIG. 3 , the second body  205  includes a camera  123 , a flash  250 , and a mirror  255 . 
     The flash  250  operates in conjunction with the camera  123 . The mirror  255  is useful for assisting a user to position the camera  123  in a self-portrait mode. 
     The camera  123  of the second body  205  faces a direction opposite to a direction faced by the camera  121  of the first body  200 . The camera  121  of the first body  200  and camera  123  of the second body  205  may have the same or different capabilities. 
     In one embodiment, the camera  121  of the first body  200  operates with a relatively lower resolution than the camera  123  of the second body  205 . Such an arrangement works well during a video conference in which reverse link bandwidth capabilities may be limited. The relatively higher resolution of the camera  123  of the second body  205  is useful for obtaining higher quality pictures. 
     The second body  205  also includes an audio output module  153  configured as a speaker which is located on an upper side of the second body. The audio output module  152  of the first body  200  and the audio output module  153  of second body  205  may cooperate to provide stereo output. Moreover, either or both of the audio output modules  152  and  153  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 . The antenna  260  functions in cooperation with the broadcast receiving module  111 . The antenna  260  may be fixed or configured to retract into the second body  205 . 
     The rear side of the first body  200  includes a slide module  265 . The slide module  265  which slideably couples with a corresponding slide module (not shown) located on the front side of the second body  205 . 
     It is understood that the illustrated arrangement of the various components of the first body  200  and the second body  205  may be modified as desired. 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 the components are not critical to many embodiments and, therefore, the components may be positioned at locations which differ from those shown by the representative figures. 
     The terminal  100  may operate in a communication system capable of transmitting data via frames or packets. The communication system may include wired communication, wireless communication, or satellite-based communication system. 
     The communication system may utilize various systems such as frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), universal mobile telecommunications system (UMTS), long term evolution (LTE) of the UMTS, or the global system for mobile communications (GSM). By way of non-limiting example, further description will relate to a CDMA communication system, but such teachings apply equally to other system types. 
     As shown in  FIG. 4 , a CDMA wireless communication system is shown having a plurality of terminals  100 , a plurality of base stations (BS)  270 , base station controllers (BSC)  275 , and a mobile switching center (MSC)  280 . The MSC  280  is configured to interface with a conventional public switch telephone network (PSTN)  290  and is also configured to interface with the BSCs  275 . 
     The BSCs  275  are coupled to the BSs  270  via backhaul lines. The backhaul lines may be configured in accordance with any of several known interfaces including 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 BS  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 BS  270 . Each sector may include two antennas for diversity reception. Each BS  270  may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum. 
     The intersection of a sector and frequency assignment may be referred to as a CDMA channel. The BSs  270  may also be referred to as base station transceiver subsystems (BTSs). In an alternate embodiment, the term “base station” may be used to refer collectively to a BSC  275  and one or more BSs  270 . 
     The BSs  270  may also be denoted “cell sites.” Alternatively, individual sectors of a given BS  270  may be referred to as cell sites. 
     A broadcasting transmitter (BT)  295  is shown broadcasting to terminals  100  operating within the system. The broadcast receiving module  111  of the terminal  100  is configured to receive broadcast signals transmitted by the BT  295 . Similar arrangements may be implemented for other types of broadcast and multicast signaling. 
       FIG. 4  also shows several global positioning system (GPS) satellites  300 . The GPS satellites  300  facilitate locating the position of some or all of the terminals  100 . The position-location module  115  of the terminal  100  is typically configured to cooperate with the satellites  300  to obtain position information. 
     Other types of position detection technology may be used in addition to or instead of GPS location technology. Some or all of the GPS satellites  300  may alternatively or additionally be configured to provide satellite DMB transmissions. 
     The BSs  270  receive sets of reverse-link signals from various terminals  100  during operation of the wireless communication system. The terminals  100  are performing calls, messaging, or other communications. 
     Each reverse-link signal received by a BS  270  is processed within that BS. The resulting data is forwarded to an associated BSC  275 . 
     The BSC  275  provides call resource allocation and mobility management functionality including 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 BSC  275 , which in turn control the BSs  270  to transmit sets of forward-link signals to the terminals  100 . 
     In the following description, steps of a broadcast controlling method of a terminal  100  according to the present invention are explained one-by-one with reference to  FIG. 5  as follows.  FIG. 5  is a flowchart for a broadcast information reception method of a terminal according to a first embodiment of the present invention. Hereinafter, a display screen of the touchscreen  151  shall be indicated by a reference number  400 . 
     A method of controlling a mobile terminal according to a first embodiment of the present invention is explained with reference to  FIGS. 5 to 7  as follows. 
       FIG. 5  illustrates a flowchart for a method of controlling a mobile terminal according to a first embodiment of the present invention. 
     As illustrated in  FIG. 5 , a list of messages is displayed on a display (S 51 ). A user may touch and drag the list of messages (S 52 ). If the list is dragged in a first direction, a preceding or following message may be displayed (S 53 , S 54 ). If the list is dragged in a second direction a message related to the selected message may be displayed (S 53 , S 55 ). 
       FIGS. 6 and 7  illustrate diagrams of a display screen for controlling a mobile terminal according to a first embodiment of the present invention. 
     As illustrated in  FIG. 6-1 , a list of received or transmitted messages may be displayed on the touchscreen  400  (S 51 ). Specifically, the messages may be sorted in top-to-bottom direction in relation to a reception or transmission time. 
     A corresponding message or information, such as a name or phone number, of a recipient or sender may be indicated for each item on the list. As illustrated in  FIG. 6 , the sender of the corresponding message may be displayed as letter from the alphabet. Additionally, a numeral may be added adjacent to the letter in order to distinguish a plurality of messages from a single sender. 
     A user may touch and drag the list of messages on the touchscreen  400  in a first direction, such as bottom-to-top (S 52 , S 53 ), as shown in  FIG. 6-1 . 
     In one example, as the messages are scrolled from bottom to top a size of the scrolled messages may be set proportional to a length of the touch and drag. 
     As illustrated in  FIG. 6-2 , a message B- 2  may be touched and dragged in a second direction, such as right-to-left. The second direction is different from the first direction (S 52 , S 53 ). 
     As illustrated in  FIGS. 6-3 and 6-4 , as the selected message B- 2  slides from right to left, another message B- 3  may appear (S 55 ). In this example, the message B- 3  is related to the selected message B- 2 . For example, the message B- 3 , may be a message which had been sent by the sender B after the message B- 2  was sent. 
     The related messages B- 2 , B- 3 , may construct a list which is different from the former list. 
     Additionally, message B- 2  may be touched and then dragged in a direction opposite to the second direction, such as left-to-right. This is explained with reference to  FIG. 7  as follows. 
     As illustrated in  FIG. 7-1 , message B- 2  is touched and then dragged left to right. Furthermore, as illustrated in  FIGS. 7-1 and 7-2  as message B- 2  slides left to right, another message B- 1  appears (S 55 ). In this example, the message B- 1  is a message which may have been sent by the sender B after the selected message B- 2  was sent. 
     In the description above description if a message is touched and dragged in a direction, another message related to the selected message is displayed by replacing the selected message. Still, before the message is touched and dragged in a direction, a terminal may display a message related to the selected message before the touch and drag is performed. 
       FIGS. 8A to 8C  illustrate diagrams of a display screen for controlling a mobile terminal according to a second embodiment of the present invention. For clarity and convenience of the following description a single message in a message list is exemplarily displayed in  FIGS. 8A to 8C .

     As illustrated in  FIG. 8A , the information  405  indicates that there are seven messages related to the selected message B- 2 , including the selected message B- 2 . Additionally, the information  405  also indicates that the selected message B- 2  is the second message of the seven messages. 
     In one example, the message B- 2  illustrated in  FIG. 8A-1  may be touched and dragged right to left. Another message B- 3  related to the selected message B- 2  may be displayed instead of the selected message B- 2  after the touch and drag. Information  405  on messages related to the message B- 3  is represented within the message B- 3 . In this example, the information  405  indicates that seven messages are related to the message B- 3 , including the message B- 3 . Additionally, the information  405  also indicates that the message B- 3  corresponds to a third message of the seven messages. 
     As illustrated in  FIG. 8B-1 , a selected message B- 2  is displayed on the touchscreen. Information on messages related to the selected message B- 2  is displayed within the selected message B- 2 . In this example, the information includes a first information  406 A and a second information  406 B. 
     The first information  406 A indicates how many messages exist on the left side of the selected message B- 2 , for example, as illustrated in  FIG. 8B-1, 1  message exists to the left of B- 2 . The second information  406 B indicates how many messages exist on the right side of the selected message B- 2 . For example, as illustrated in  FIG. 8B-1 , 5 messages exist to the right of B- 2 . 
     If the selected message B- 2  is touched and dragged right to left. A second message B- 3  related to the selected message B- 2  is displayed. The first information  406 A and second information  406 B may be represented within the displayed message B- 3 . In this example, the first information  406 A indicates that 2 messages exist to the left of B- 3 . Additionally, the second information  406 B indicates that 4 messages exist to the right of B- 3 . 
     As illustrated in  FIG. 8C-1 , a selected message B- 2  may be displayed on the touchscreen. Information  405  on messages related to the specific message B- 2  is represented as a bar within the selected message B- 2 . 
     The bar  407  includes scale marks corresponding to the selected message B- 2  and the related messages, such as B- 1 , B- 3 , B- 4 , respectively. A terminal user may understand how many related messages exist in relation to the selected message B- 2  by visually distinguishing the scale mark corresponding to the selected message B- 2  from the other scale marks within the bar  407 . 
     As illustrated in  FIG. 8C-1  the selected message B- 2  may be touched and dragged right to left. Another message B- 3  related to the selected message B- 2  then replaces the previously displayed message B- 2 .
