Such efforts include not only changes and improvements in the structural components that form the mobile terminal but also additions and improvements of software and hardware.

For example, a broadcasting service may be provided by installing a separate broadcasting module (broadcasting chipset or RF module) in the mobile terminal, and a multimedia broadcasting / multicast service (hereinafter abbreviated as MBMS) It is possible to receive multimedia contents in a broadcast form in a 3GPP R6 based mobile communication network.

However, in order to receive the broadcasting service, a separate broadcasting module (broadcasting chipset or RF module) is required in addition to the communication module, and there is no way to access the broadcasting service until the user enters the broadcasting mode directly .

In addition, when a user enters a multicast mode, a mobile terminal having an MBMS function monitors all MBMS control channels (MBMS Control Channels) for a service that the user does not want to obtain service information, There was a drawback to be consumed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mobile terminal capable of efficiently receiving a broadcast / multicast service (MBMS) using radio resources of a 3G network and a method for acquiring a preferred service.

According to an embodiment of the present invention, there is provided a method of acquiring a preferred service of a mobile communication terminal, the method comprising: displaying a service guide; Reserving information set by a user as a preferred service in a service guide; Displaying the reserved preferred service on a standby screen; And monitoring the service channel every predetermined period in the standby mode to obtain a reserved preferred service.

According to an embodiment of the present invention, there is provided a mobile communication terminal including a display unit displaying a service guide; And displays the preference information set by the user in the service guide on the idle screen as a preferred service and monitors the service channel in the idle mode at regular intervals to update the displayed preference service.

The reserved preferred service is displayed on the idle screen as one of a pop-up form, a representative icon form, and a preferred keyword form.

The service guide may include at least one preferred service list, and each preferred service list may be displayed with respective icons.

The at least one icon may be integrated and separated by touching and dragging.

The reserved preferred services are displayed and updated periodically by priority or category.

If it is detected that the reservation service can not be acquired during the acquisition of the preference service, the user is informed of the status in which the reserved service can not be acquired and the next request operation is inquired.

And a state in which the reserved service can not be acquired is notified through pop-up, voice, or vibration.

The state in which the reserved service can not be acquired includes a call in a power off state, a low battery state, a no service state, a bad reception environment (reception sensitivity degradation), and a call in a broadcast mode.

The mobile terminal and its preferred service acquisition method according to an embodiment of the present invention can provide a useful MBMS service through terminal implementation without having to additionally provide a broadcast module unlike the conventional mobile TV.

In addition, according to the present invention, a desired service information is selectively reserved in a service guide (SA), and compared with each service provided in a 3G network, only a reserved service is received, thus unnecessary MBMS control information reception The power consumption can be reduced.

Hereinafter, a mobile terminal related to the present invention will be described in more detail with reference to the drawings.

The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and a broadcast signal in which a data broadcast signal is combined with a TV broadcast signal or a radio broadcast signal.

Meanwhile, the broadcast related information may be provided through a mobile communication network, and in this case, it may be received by the mobile communication module 112.

The broadcast-related information may exist in various forms. For example, an EPG (Electronic Program Guide) of DMB (Digital Multimedia Broadcasting) or an ESG (Electronic Service Guide) of Digital Video Broadcast-Handheld (DVB-H).

The broadcast receiving module 111 receives broadcasting signals using various broadcasting systems. In particular, the broadcasting receiving module 111 may be a Digital Multimedia Broadcasting-Terrestrial (DMB-T), a Digital Multimedia Broadcasting-Satellite (DMB-S) Only Digital Broadcast-Handheld (DVB-H), Integrated Services Digital Broadcast-Terrestrial (ISDB-T), and the like. Of course, the broadcast receiving module 111 is configured to be suitable for all broadcasting systems that provide broadcasting signals as well as the digital broadcasting system described above.

The broadcast signal and / or broadcast related information received through the broadcast receiving module 111 may be stored in the memory 160.

In addition, the mobile communication module 112 transmits and receives radio signals to at least one of a base station, an external terminal, and a server on a mobile communication network. Here, the wireless signal may include various types of data depending on a voice call signal, a video call signal, or a text / multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and the wireless Internet module 113 can be built in or externally. WLAN (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access) and the like can be used as wireless Internet technologies.

The location information module 115 is a module for confirming or obtaining the location of the mobile terminal. A typical example of the position information module 115 is a Global Position System (GPS) module. According to the present technology, the GPS module calculates distance information and accurate time information from three or more satellites, and then applies trigonometry to the calculated information to obtain three-dimensional current position information according to latitude, longitude, and altitude It can be calculated accurately. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module can calculate speed information by continuously calculating the current position in real time.

An audio / video (A / V) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes an image frame such as a still image or a moving image obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame can be displayed on the display module 151.

The image frame processed by the camera 121 may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ The camera 121 may be equipped with two or more cameras according to the configuration of the terminal.

The microphone 122 receives an external sound signal through a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output. The microphone 122 may be implemented with various noise reduction algorithms for eliminating noise generated in the process of receiving an external sound signal.

The user input unit 130 generates input data for a user to control the operation of the terminal. The user input unit 130 may include a key pad, a dome switch, a touch pad (static / static), a jog wheel, a jog switch, and the like. Particularly, when the touch pad has a mutual layer structure with the display module 151 described later, it can be called a touch screen.

The sensing unit 140 senses the current state of the mobile terminal 100 such as the open / close state of the mobile terminal 100, the position of the mobile terminal 100, the presence or absence of user contact, the orientation of the mobile terminal, And generates a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. Also, it is responsible for a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like. Meanwhile, the sensing unit 140 may include a proximity sensor 141. This will be described later in connection with touch screens.

The interface unit 170 serves as an interface with all external devices connected to the mobile terminal 100. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, Video input / output (I / O) ports, earphone ports, and the like.

Here, the identification module is a chip that stores various information for authenticating the use right of the mobile terminal 100, and includes a user identification module (UIM), a subscriber identity module (SIM) ), A Universal Subscriber Identity Module (" USIM "), and the like. In addition, an apparatus having an identification module (hereinafter referred to as 'identification device') can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port. The interface unit 170 receives data from an external device or receives power from the external device to transfer the data to each component in the mobile terminal 100 or to transmit data in the mobile terminal 100 to an external device.

The interface unit 170 may be a path through which power from the cradle is supplied to the mobile terminal 100 when the mobile terminal 100 is connected to an external cradle, Various command signals may be transmitted to the mobile terminal. The various command signals or the power source input from the cradle may be operated as a signal for recognizing that the mobile terminal is correctly mounted on the cradle.

The output unit 150 is for outputting an audio signal, a video signal, or an alarm signal. The output unit 150 may include a display module 151, an audio output module 152, and an alarm unit 153.

The display module 151 displays and outputs information processed by the mobile terminal 100. For example, when the mobile terminal is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. If the mobile terminal 100 is in the video communication mode or the photographing mode, the captured image and / or the received image or UI and GUI are displayed.

Meanwhile, as described above, when the display module 151 and the touch pad have a mutual layer structure to constitute a touch screen, the display module 151 can be used as an input device in addition to the output device. The display module 151 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three-dimensional display 3D display). Some of these displays can be configured to be transparent so that they can be viewed from outside. This may be referred to as a transparent display. A typical example of the transparent display is a transparent organic light emitting diode (TOLED) or the like. In addition, there may be two or more display modules 151 according to the embodiment of the mobile terminal 100. For example, the mobile terminal 100 may be provided with an external display module (not shown) and an internal display module (not shown) at the same time. The touch screen may be configured to detect not only the touch input position and area but also the touch input pressure.

Meanwhile, the proximity sensor 141 may be disposed inside or near the touch screen. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. Therefore, the proximity sensor 141 has a considerably long life span and its utilization is also significantly higher than that of the contact-type sensor.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

An example of the operation of the high-frequency oscillation-type proximity sensor will be described. In a state where a high frequency of a stationary wave is oscillated in an oscillation circuit, when the sensing object approaches the vicinity of the sensor sensing surface, the oscillation amplitude of the oscillation circuit attenuates or stops , And these changes are converted into electrical signals to detect the presence or absence of the sensing object. Therefore, even if any non-metallic substance comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

The proximity sensor 141 may be configured so as to detect the proximity of the pointer with the change of the electric field along the proximity of the pointer if the touch screen is electrostatic.

Accordingly, when the pointer is not actually touched on the touch screen but is located close to the touch screen, the position of the pointer and the distance between the pointer and the touch screen can be detected. Hereinafter, for the sake of convenience of description, the act of allowing the pointer to be located on the touch screen to recognize that the pointer is positioned on the touch screen is referred to as "proximity touch ", and a pointer The actual touching action will be referred to as "contact touch. &Quot; In addition, a position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects proximity touches and proximity touch patterns (e.g., proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, and the like) , And may output information corresponding to the detected proximity touch operation and the proximity touch pattern on the touch screen.

The audio output module 152 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output module 152 outputs an acoustic signal related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for informing occurrence of an event in a form other than an audio signal or a video signal. For example, it is possible to output a signal in a vibration mode. When a call signal is received or a message is received, the alarm unit 153 can output a vibration to notify it. Alternatively, when the key signal is input, the alarm unit 153 can output the vibration by the feedback to the key signal input. The user can recognize the occurrence of an event through the vibration output as described above. Of course, a signal for notifying the occurrence of an event may also be output through the display module 151 or the sound output module 152.

The memory 160 may store a program for processing and controlling the control unit 180 and may store a function for temporarily storing input / output data (e.g., a phone book, a message, a still image, . In addition, the memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory) SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read- And may include at least one type of storage medium among the optical discs. Also, the mobile terminal 100 may operate a web storage for performing a storage function of the memory 160 on the Internet.

The control unit 180 typically controls the overall operation of the mobile terminal. For example, voice communication, data communication, video communication, and the like. In addition, the control unit 180 may include a multimedia module 181 for multimedia playback. The multimedia module 181 may be implemented in the control unit 180 or may be implemented separately from the control unit 180. [

The controller 180 may perform a pattern recognition process for recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components.

The various embodiments described herein may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

The mobile terminal 100 mainly operates in the standby mode in the closed state, but the standby mode is also released by the operation of the user. The mobile terminal 100 operates mainly in a communication mode in an open state, but is also switched to a standby mode by a user's operation or a predetermined period of time.

The casing (casing, housing, cover, etc.) constituting the outer appearance of the first body 200 is formed by the first front case 220 and the first rear case 225. Various electronic components are installed in a space formed by the first front case 220 and the first rear case 225. At least one intermediate case may be additionally disposed between the first front case 220 and the first rear case 225.

The cases may be formed by injection molding of a synthetic resin or may be formed of a metal material such as stainless steel (STS) or titanium (Ti).

The display unit 151, the sound output module 152, the camera 121 or the first user input unit 210 may be disposed in the first body 200, specifically, the first front case 220.

The sound output module 152 may be implemented in the form of a speaker.

The camera 121 may be implemented to suitably photograph an image or a moving image for a user and the like.

As in the case of the first body 200, the case constituting the outer appearance of the second body 205 is formed by the second front case 230 and the second rear case 235.

The second user input unit 215 may be disposed on the front surface of the second body 205, specifically, the second front case 230.

The third user input unit 245, the microphone 122, and the interface unit 170 may be disposed in at least one of the second front case 230 and the second rear case 235.

The power supply unit 190 may be detachably coupled to a rechargeable battery, for example, for charging.

3 is a rear perspective view of the mobile terminal of FIG.

Referring to FIG. 3, a camera 121 may be further mounted on the rear surface of the second rear case 235 of the second body 205. The camera 121 of the second body 205 has a photographing direction which is substantially opposite to that of the camera 121 of the first body 200 and a different pixel from the camera 121 of the first body 200 Lt; / RTI >

For example, the camera 121 of the first body 200 has low pixels so that it is easy to capture a face of a user in the case of a video call or the like and transmit it to the other party, Since it is often the case that a subject is photographed and not immediately transferred, it is preferable to have a high pixel.

A flash 250 and a mirror 255 may be additionally disposed adjacent to the camera 121 of the second body 205. The flash 250 illuminates the subject when the subject of the subject is photographed by the camera 121 of the second body 205. The mirror 255 allows the user to illuminate the user's own face or the like when the user intends to take a picture of himself / herself (self-photographing) using the camera 121 of the second body 205.

The location information module 115 shown in FIG. 1 cooperates with satellites 300 to obtain desired location information. Here, you can track your location using all of the technologies that can track your location, as well as your GPS tracking technology. Also, at least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

Among the typical operations of a wireless communication system, the BS 270 receives a reverse link signal from the various terminals 100. At this time, the terminals 100 are connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by the particular base station 270 is processed by the particular base station 270. The data resulting from the processing is transmitted to the connected BSC 275. The BSC 275 provides call resource allocation and mobility management functions, including the organization of soft handoffs between the base stations 270. The BSC 275 also transmits the received data to the MSC 280 and the MSC 280 provides additional transmission services for connection with the PSTN 290. [ Similarly, the PSTN 290 connects to the MSC 280, the MSC 280 connects to the BSCs 275, and the BSCs 275 communicate with the BSs 270 ).

UMTS (Universal Mobile Telecommunications System) is a 3G mobile communication system that evolved from the European standard GSM (Global System for Mobile Communications) system. It is based on the GSM core network and WCDMA (Wideband Code Division Multiple Access) And aims at providing more improved mobile communication service.

The UMTS system is composed of a mobile terminal, a UMTS Terrestrial Radio Access Network (UTRAN), and a core network (CN). The radio access network provides a Multimedia Broadcast / Multicast Service (MBMS) to a mobile terminal.

A broadcast / multicast service (MBMS) is a service for providing a streaming or a background service to a plurality of terminals using a downlink dedicated MBMS bearer service. One MBMS service is composed of one or more sessions, and MBMS data is transmitted to a plurality of terminals through an MBMS bearer service while a session is ongoing. At this time, the UTRAN uses a point-to-multipoint radio bearer and a point-to-point radio bearer service.

The MBMS is divided into a broadcast mode and a multicast mode. The MBMS broadcast mode is a service for transmitting multimedia data to all users in a broadcast area, and the MBMS multicast mode transmits multimedia data only to a specific user group in a multicast area Service. Here, the broadcast area refers to an area where a broadcast service is available, and the multicast area refers to an area where a multicast service is available. The broadcast area and the multicast area are referred to as a service area.

The UTRAN providing the MBMS service transmits MCCH information (control information) to a plurality of terminals through an MBMS Control Channel (MCCH), which is a logical channel. The MCCH is used to transmit MBMS related control information as point-to-multipoint downlink channels. The MCCH is mapped to a forward channel (FACH), and the FACH is mapped to a secondary common control physical channel (SCCPCH). There is only one MCCH in one cell.

5 is a diagram illustrating a process in which a UMTS network provides an MBMS service using a multicast mode, and is an example of a process in which a UE receives a specific service.

As shown in FIG. 5, a mobile terminal that wishes to receive an MBMS service must perform a subscription procedure. Here, subscription refers to an act of establishing a relationship between a service provider and a user.

In addition, terminals receiving MBMS service must receive a service announcement (SA) provided in a mobile communication system (UMTS network). Here, the service guidance is a function of notifying the terminal of a list of services to be provided in the future and related information.

A terminal desiring to receive a multicast mode MBMS service must join a multicast group, i.e., a group of terminals receiving a specific multicast service. Herein, the term " participation " refers to a process in which a terminal joins a multicast group to receive a specific multicast service. Through the participation process, the MS can inform the UMTS network of the intention to receive the specific multicast data. On the other hand, the process of terminating participation in a multicast group by a terminal participating in a specific multicast group is called leave. The joining, joining, and leaving processes are performed for each mobile station, and the mobile station can perform joining, joining, and withdrawing processes at any time before, during, or after data transmission.

During the course of a particular MBMS service, one or more sessions for that service may occur sequentially. When data to be transmitted to a specific MBMS service occurs in the MBMS data source, the CN informs a Radio Network Controller (RNC) managing the base stations in the UMTS network of the session start (Session Start). On the other hand, if there is no more data to be transmitted for a specific MBMS service in the MBMS data source, the CN informs the RNC of the session stop. A data transfer process for a specific MBMS service can be performed during a session start and a session stop. At this time, only terminals participating in a multicast group for a specific MBMS service can receive data transmitted through the data transmission process.

In the session initiation process, the RNC receiving the session initiation from the CN sends an MBMS notification to the UEs. Here, the MBMS notification refers to a function that the RNC notifies the UE that data transmission of a specific MBMS service is imminent in a certain cell. The MBMS notification is transmitted at least once before the actual data of the service is transmitted.

The present invention provides a variety of access scenarios for an MBMS service, thereby enhancing user convenience. For example, the present invention provides a mobile communication system (or UMTS network) in which a mobile terminal receives a service guide (SA) provided in a mobile communication system (or UMTS network) Service.

Also, the broadcast mode does not perform the join, join, and withdraw process in the multicast mode shown in FIG.

6 is a flowchart illustrating an MBMS service acquisition method of a mobile communication terminal according to an embodiment of the present invention.

As shown in FIG. 6, the present invention provides a service providing method, comprising: receiving a service guide (SA) from a service provider or a mobile communication network (or a system) And a step (S11) of creating a list (Wished service list).

The service guide (SA) receives SMS (Shot Message Service), MMS (Multimedia Messaging Service) cell broadcasting and WAP Push. The service guidance SA includes a service name, a service ID (+ session ID), a service start / end time, a service class, a description, a content type, a media type (AVI, MPEG, TXT, Of IP / UDP ports.

The control unit 180 controls the display unit 151 to display the received service guide (SA) in a pop-up form on the terminal screen. FIG. 7 shows an example of a received service guide (SA). As shown in FIG. 7, the service guide (SA) includes various information for service acquisition, and each service list is divided into service IDs. Also, each service list may include the following contents information.

- Channel name (real-time information channel, game channel, movie channel, video advertisement, broadcast channel, etc.)

- Type of service (download, streaming, carousel, etc.)

- Content type (news breaking news, real-time weather information, soccer, sightseeing image information, etc.)

- Content description and Preview

- Media type (Text, Flash file, AVI, JPG, etc.)

Accordingly, the user can select the specific service list (for example, the service list 1), confirm the detailed information of the list, and proceed with the preference information reservation. If the reservation setting is selected from the specific service list, the control unit 180 provides a screen for setting a reservation for the service list desired by the user.

Accordingly, the user confirms the broadcast time, the content type, and the media type from the SA displayed on the screen, and then reserves preference information of interest to the user. For example, a user can watch a broadcast, store a broadcast, view / save a VOD movie, or download a file. In addition, the user can set a method (notification, pop-up, vibration, and audio) to notify the user at the start (end) of the reception of the reserved contents.

In addition, the user can reserve the reception method (eg, streaming, download, carousel, etc.) from the SA, and can execute the reserved preference information (setting of the alarm method, downloading, recording, Etc.) can be additionally set.

For example, in the case of an alarm reservation, the user sequentially performs a hot-link click on the screen, a broadcast schedule confirmation in SA, and a reserved alarm setting for specific content (setting the alarm for 00 minutes before broadcast starts). As another example, when setting a recording schedule, the user performs a hot-link clicking on the screen, a broadcast schedule check, and a recording schedule.

FIG. 8 shows an example of a screen for setting a reservation for a service list in the present invention.

8, when the user selects a specific service list (CNN in the present invention), the control unit 180 provides start time, end time, and alarm setting for the CNN, and the user confirms (or yes) To set a reservation for a specific service list. The user repeatedly performs such an operation on at least one service list.

Once the service list or the preference information of interest is reserved by the user, the control unit 180 edits the corresponding preference information by category (title, time, priority, ...) to select a preferred service list And stores it in the memory 160. Before storing the preference service list in the memory 160, the control unit 180 displays the preference service list to the user for confirmation.

Also, in the present invention, the preferred service list can be automatically set without a reservation of a user. That is, the control unit 180 can automatically set the preference information from the service guide (SA) based on the preference information preset by the user, for example, the user's gender, age, location, . At this time, the user can also apply the priority to the preference information reservation setting. For example, only fishing, weather, drama, and action movies can be automatically selected to inform the user in preference to other services.

In the standby state, the control unit 180 displays the progress status of the reserved preferred service list on a standby screen or a separate screen (pop-up) (S12). The displayed preferred service list is updated as time elapses, and the display method thereof can be variously applied.

9 shows an embodiment in which a pre-reserved service is displayed on a standby screen.

As shown in FIG. 9, the controller 180 may display a list of reserved preferred services on the idle screen according to a priority order or a category. If not, the randomized display is displayed. The content to be displayed includes a brief content of the broadcast service currently being served, that is, a title, a content and a time.

10A and 10B show another preferred embodiment of displaying the pre-reserved preferred service on the idle screen, in which the preferred service list is displayed in the pop-up window 50. [

10A, when the preferred service list is displayed in the pop-up window 50, the control unit 180 does not display all the preferred services lists on the pop-up window 50, Up window 50 so that the remaining favorite service list is displayed on the touch after displaying only the pop-up window 50 (or representative).

As shown in FIG. 10B, the controller 180 may display only the minimum number (or representative) of the pop-up window 50 according to the priority order as shown in FIG. 10A, and then, by touching and dragging, 50) is expanded, the remaining preferred services list is displayed. At this time, the minimum number of the displayed preferred services list can be set by the user.

11 shows another preferred embodiment of displaying the pre-reserved preferred service on the idle screen, wherein the preferred service list is shown as a separate icon.

11, the controller 180 includes an icon for accessing the preferred service list on the idle screen. When the icon is touched, the preferred service list is displayed. In the displayed preferred service list, When the content is selected, for example, the title of the content, the start time of the reservation. End time, and alarm set time.

The embodiment shown in FIG. 11 can be effective when it is not possible to display on the terminal screen due to a large number of reserved preferred services lists, or when it is not good for a large number of lists.

In addition, when the preferred service list is represented by an icon as described above, the icons may be provided for each category constituting the preferred service list

12A and 12B are diagrams illustrating an example of integrating or separating icons when the preferred service list is displayed as a separate icon.

As shown in FIG. 12A, an icon 52 for the category, for example, CNN, and an icon 53 for the professional baseball on the idle screen are displayed as one icon 51 by touch and drag Can be integrated.

12B, when the icon 51 is touched to display a list of preferred services and a specific list (eg, CNN) is touched and dragged out of the pop-up window or the idle screen, a new one And displays it.

In addition, the controller 180 may display preference keywords such as a favorite movie genre, a favorite artist name, a preferred time zone, and the like, without displaying the favorite screen on the idle screen. These various pop-ups, icons, and the like can be moved or changed in shape by the user.

Meanwhile, while displaying the reserved preferred service list on the idle screen, the controller 180 monitors the paging channel every predetermined period to acquire the reserved service, as shown in FIG. This operation means that it is possible to monitor / access broadcast information even if the user does not execute the broadcast service.

6, the terminal 180 in the idle state wakes up at predetermined time intervals (DRX cycle) according to the MBMS standard protocol and transmits a Notification Indicator (NI) transmitted via an MBMS paging indication channel (MICH) (S13). If the terminal participates in a specific multicast group in a multicast mode rather than in a standby state, the terminal can receive the NI through a dedicated control channel (DCCH). 13 shows the TMGI structure included in NI.

The controller 180 detects the MBMS service ID in the TMGI structure included in the NI, compares the corresponding MBMS service ID with the service ID of the preferred service list (S14), and confirms whether the reserved service is detected. If it is determined that the two service IDs are identical and the reserved service exists, the controller 180 receives the downlink control information, that is, the MBMS control channel (MCCH) , And an MBMS traffic channel (MCCH) (S15).

Accordingly, the control unit 180 receives the content from the mobile communication network through the established MTCH and performs an operation for executing a predetermined service by the user, for example, an alarm, a pop-up, Download, real-time recording, operation notification, indicator setting, and the like (S16).

Thereafter, the control unit 180 repeatedly performs the operations after step S12 for all services reserved for the above-described operations (S17). At this time, the controller 180 updates the progress status of the reserved service on the idle screen and displays it.

That is, unlike other broadcast services, since the MBMS paging panel (MICH) and the MBMS control channel (MCCH) are periodically monitored in the conventional 3G standby state, the controller 180 continuously obtains information on the currently broadcasted service have. Accordingly, the control unit 180 displays simple information of the broadcast service (MBMS content) currently being serviced, that is, title / content / time, etc., in real time along with the currently registered favorite service on the idle screen, and periodically updates it.

FIG. 14 shows an example of displaying a broadcasting service currently being serviced and a reserved preferred service on a standby screen.

As shown in FIG. 14, when the controller 180 receives a reservation service, the control unit 180 determines whether the title / content / service of the broadcast service (MBMS content) Time and so on.

On the other hand, if the control unit 180 can not acquire the reserved service until the reserved time (including not detecting the reserved service or disconnecting while receiving the content of the reserved service) . The specific case is as follows.

- Power off state

- Low charge state

- No (No) Service Status

- Bad reception environment (low reception sensitivity)

- In case of a call during broadcasting mode

When a case in which various reserved services are not obtained as described above, the control unit 180 notifies the user of the situation and displays an item or message for requesting the user to perform the next operation.

FIG. 15 is a flowchart showing a reservation service acquisition method at power-off.

The controller 180 wakes up at a predetermined time interval (DRX cycle) in the standby state, and monitors the MBMS paging indication channel (MICH) to acquire a reserved service. However, the power of the terminal may be turned off when the MICH is not monitored for a predetermined time.

15, when the power of the terminal is turned on again (S20), the control unit 180 determines whether the power of the terminal is reserved in the memory 160 during power-off through a separate pop-up, (S21), and displays a message asking whether to continue the service (s) (S22).

If the user requests the progress of the corresponding service (s), the control unit 180 automatically schedules the corresponding service and acquires the service at the searched time (S23, S24). On the other hand, if the user does not want to continue the service, the control unit 180 performs the reservation operation again (S25), and obtains the reserved service using the above-described method. In particular, when the service period of the specific service content reserved during power-off has expired, the control unit 180 requests the same service content purchase through the mobile communication network (when the service re-viewing service is supported).

16 is a flowchart showing a reservation service acquisition method in a low charge state.

As described above, when the user reserves the preferred service, the control unit 180 monitors the MICH until the reserved time and acquires the reserved preferred service. However, if the remaining battery capacity is insufficient until the reserved time, the user can not receive desired service contents by acquiring the preferred service. Accordingly, the controller 180 compares the battery remaining amount with the service reservation time (S31) when the user reserves the preferred service (S30), and confirms whether the battery remaining amount is sufficient until the reservation time (S32).

If the battery remaining amount is sufficient, the controller 180 monitors the MICH to receive the MCCH, and then acquires the reserved service based on the MCCH. On the other hand, if the battery remaining amount is not sufficient, the control unit 180 notifies the user that the reserved service can not be performed through pop-up, voice, or vibration and requests the user to perform the next operation (S35). At this time, the request operation is provided in the form of a message in the form of a cancellation of a reservation, a reservation advance when a battery is charged to a certain level, and the like so that a user can select the request.

17 is a flowchart showing a method of acquiring a reservation service in a bad reception environment.

Referring to FIG. 17, when the network environment, for example, the channel state is poor, the receiving sensitivity of the signal provided by the mobile communication network deteriorates. The control unit 180 compares the reception sensitivity of the terminal with the reference sensitivity (S40 to S42). If the reception sensitivity of the terminal is higher than a predetermined reference value, the controller 180 monitors the MICH to receive the MCCH, (S43, S44).

On the other hand, if the reception sensitivity of the terminal is less than a predetermined reference value, the controller 180 notifies the user that the reserved service can not be performed through pop-up, voice, or vibration, The user is requested (S45). At this time, the request operation provides a message form such as a reservation cancellation, a retry when a certain reception sensitivity is satisfied, a next schedule search when a certain reception sensitivity is satisfied, a reservation request for the same contents repurchase request and a similar contents retrieval upon expiration of a period, To be selected.

18 is a flowchart showing a method of acquiring a reservation service when a call is generated during a broadcast mode.

Referring to FIG. 18, when a call is generated during the broadcast mode, the controller 180 displays a message asking the user whether to continue the scheduled service. If the user decides to continue the reserved service by viewing the message, the control unit 180 simultaneously performs the call and broadcast mode on one screen. Accordingly, the user can view the reserved service through the screen while continuing the conversation with the other party.

On the other hand, if the user decides not to continue the reserved service, the control unit 180 retransmits the same to the same network after the call is terminated, requests retransmission (or re-purchase), or automatically reserves the next scheduled identical content.

As described above, the mobile terminal according to the present invention having the MBMS function does not need to additionally provide a broadcast module unlike the conventional mobile TV. Since the existing mobile network resource is used as it is, the terminal can always receive broadcast control information (MCCH) Lt; / RTI > In particular, according to the present invention, a desired service information is selectively reserved in a service guide, and compared with each service provided in a 3G network, only a reserved service is received, thereby consuming unnecessary power consumed in reception of unnecessary MBMS control information Can be reduced. The present invention provides useful services only through terminal implementation without further modification of the network.

Further, according to an embodiment of the present invention, the above-described method can be implemented as computer-readable code on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . Further, the computer may include a control unit of the terminal.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
