The present invention relates to a mobile communication system having a multi-channel guide function using scalability, and a control method thereof. In particular, a multi-channel guide screen includes a next-generation scalability distribution server except a multi-channel server unit. The present invention relates to a mobile communication system having a multi-channel guide function using scalability which can significantly improve the display characteristics of the multi-channel guide signal of the mobile communication system by a plurality of connection control methods.

In general, terminal equipment, which is one of the mobile communication systems, has been commercialized in the United States in the early 1980s, and recently, such terminal equipment has been provided with various services in connection with a high-speed internet network through a mobile communication network. For example, a multimedia transmission service, a movie ticket reservation through the Internet, or a digital multimedia broadcasting (DMB) service has been successfully executed.

Here, the DMB service installed in the terminal equipment is a broadcasting service that provides various multimedia signals such as voice and video to a digitally fixed, portable, and vehicle receiver, and is compact through personal portable information (PDA) or vehicle terminal equipment while moving. High-quality, high-definition broadcasting such as a disc (CD) or a digital video disc (DVD) can be provided, and three systems such as systems A, Dh, and E are used. At this time, the system A follows the European Digital Broadcasting Standard (OFDM: Orthogonal Frequency Division Multiplexing) of digital satellite broadcasting and terrestrial digital multimedia broadcasting (DMB), and the system Dh is based on the terrestrial DMB, but accommodates the satellite DMB. The system E adopts a code division multiple access (CDM) which is almost the same as the code division multiple access (CDMA).

In addition, in recent years, such a DBM is combined with the terminal equipment to have a state-of-the-art broadcasting environment that changes from joint viewing to individual viewing, fixed viewing to mobile viewing, and broadcasting to personal casting. In particular, the above-mentioned DMB is divided into terrestrial and satellite waves. Among the satellite DMB, when the program is transmitted to the satellite from the broadcasting center, the satellite spreads it to the DMB terminal equipment throughout the country, and in the shaded areas such as the city where the reception rate is low. A repeater called Gap Filler is installed to prevent dropping. On the other hand, the terrestrial DMB is a method of receiving DMB broadcasting using the empty airwaves VHF 12 and 8 channels, and receives the radio wave transmitted from the transmission tower through the terminal equipment.

Then, referring to FIG. 1, a mobile communication system equipped with a conventional DMB function as described above, receives a TV broadcast signal transmitted from a satellite 70 or a transmission tower 71, displays it on the LCD panel 72, and wirelessly. Terminal equipment 73 for processing call signals, base stations 74 for wirelessly processing function signals, for example, call signals and SMS messages transmitted from terminal equipment 73, and input via the base station 74 And an MSC 75 for processing the call signal.

On the other hand, looking at the operation of the conventional mobile communication terminal equipment as described above, first, if the user of the terminal equipment 73, for example, to send an SMS message, the user of the terminal equipment 73 is the keypad 76 of the terminal equipment 73 ) To select the appropriate menu and then enter the required character. Then, when the character input is completed through the above process, the user of the terminal equipment 73 presses the keypad 76 to select a destination telephone number to be transmitted from the phonebook list stored therein, and then presses the transfer button. Then, the terminal equipment 73 transmits the text data input by the user in the SMS message to the base station 74. Therefore, the SMS message signal of the terminal equipment 73 is input to and stored in the SMS message center 77 via the base station 74 and the MSC 75. Then, the SMS message center 77 checks the destination phone number of the input SMS message and transmits it to the MSC 75. Then, the MSC 75 transmits the SMS message signal transmitted from the SMS message center 77 to the counterpart terminal device 78. The counterpart terminal device 78 analyzes the received SMS message signal and displays the signal on the display unit.

On the other hand, if the terminal equipment 73, for example, the satellite DMB function is set during the process, the terminal equipment 73 displays the DMB menu on the LCD panel 72 (wherein the DMB signal is a base station of the mobile communication network ( Transmission and reception can also be performed via 74). At this time, the terminal equipment 73, before watching the TV by the DMB, first, EPG (Electronic Program Guide) that informs the channel signals that are currently executed (Service to help the user to easily select programs coming out through a number of channels) service signal Is received from the satellite 70 or the transmission tower 71 or the repeater or the mobile communication base station 74 and displayed on the LCD panel 72. Here, only the channel and meta information (name of the main program) are displayed in the EPG signal.

And, if the user of the terminal equipment 73 to set the channel that he wants to watch on the DMB menu screen on which the EPG screen is displayed on the LCD panel 72 by adjusting the key panel unit 76, the terminal equipment 73 is The TV channel signal selected by the user is received from the satellite 70 or the base station 74 or the terrestrial DMB from the transmission tower 71 or the base station 74 and displayed on the LCD panel 72. You will watch. Here, in the EPG channel setting process, if the channel contents of the EPG are not satisfied by the user of the terminal equipment and change to another channel, the EPG display menu screen may be returned to another EPG channel.

However, the conventional mobile communication system having the DMB function displaying the EPG signal is a method that takes a certain time to convert from the EPG screen to the channel signal, so that the user of the terminal equipment wants to change the channels displayed on the EPG screen in order. Not only a considerable channel selection time is required until the channel is selected, but also a user's operation is very inconvenient according to the selection, and thus has a disadvantage in significantly reducing the usability of the mobile communication system having the DMB function.

In addition, in the mobile communication system having the MB function as described above, since the session connected between the terminal equipment and the wireless access network system is not connected for each display channel, the user of the terminal equipment changes the current channel to another channel or changes the general screening channel. If you choose to terminate the current session and connect the session of a new channel again, and because the quality of each channel can not be controlled individually, there is a problem that significantly reduces the high quality of the mobile communication service possessing the DMB function.

Accordingly, the present invention has been invented to solve the above-mentioned problems, the user of the DMB function terminal equipment immediately grasps a plurality of channel information displayed on the multi-channel guide matrix screen at a glance to the desired channel screen Accordingly, an object of the present invention is to provide a mobile communication system having a multi-channel guide function using scalability that maximizes user convenience of a mobile communication service and a control method thereof.

Set to display.

For example, the matrix screen of the display unit 1 implemented according to the multi-channel guide signal of the DMB, as shown in (a) and (b) of FIG. , 3 × 3, 4 × 4 ...)

On the other hand, the main control unit 5 of the terminal equipment 2, if the number of channels to be displayed on the display unit 1 is not able to show all the channel signals on one screen, by changing the channel signals at a predetermined time interval multi It can also be displayed in the channel guide screen method. For example, when the matrix screen composition ratio that can be implemented by the display unit 1 is 2 × 2, the display unit 1 may be displayed by changing the screens at 5 second intervals by dividing four channels at a time.

Meanwhile, when a user of the terminal equipment 2 selects any one of a plurality of channel signals (multi-channel guide screen) displayed on one screen of the display unit 1, the wireless access network system transmits the selected channel signal. It transmits to the multichannel system part 14 via the base station system part 13 of 3). The main control unit 5 of the terminal equipment 2 receives the selected channel signal from the multi-channel system unit 14 through the DMB signal processor 4 on the display unit 1. Display as a full signal to execute the normal DMB function.

Next, the second system of the present invention as described above. Example  Explain.

In the multi-channel system unit 14 of the second embodiment of the present invention, as shown in FIG.

A plurality of channel servers 15a-n and a plurality of channel servers 15a-n, which encode a plurality of DMB content channel signals in a manner capable of scalability and then output the encoded data, respectively. The scalability distribution server 19 generates and outputs various DMB channel signals of various contents in various channel modes in response to a request of a terminal device to which a plurality of sessions are connected.

Here, the terminal equipment 2 may request various channel mode signals to the scalability distribution server 19 to which the plurality of sessions are connected via the base station system unit 13.

The channel mode of the scalability distribution server 19 includes a normal channel screening mode, a multichannel screening mode, a specific channel selection mode during multichannel use, and a multichannel switching mode during normal channel screening.

That is, in the normal channel screening mode, the scalability distribution server 19 receives data of the degree of scalability that the terminal equipment can receive only from a specific server selected by the terminal equipment 1 among the channel servers 15a-n. On the display unit 1 of the terminal device 2 by transmitting the minimum scalability data and enough detail data thereof to the terminal device 2 through a session connected to the terminal device 2 which has been provided. This mode is for displaying one channel data to have an optimal quality.

In the multi-channel screening mode, the scalability distribution server 19 receives the encoded channel signals from the plurality of channel servers 15a-n with the minimum scalability, and then processes them as multi-channel guide screens. This is a mode for displaying one screen on the display unit 1 of (2).

In addition, the specific channel selection mode during the multi-channel use, when the scalability distribution server 19 provides a multi-channel guide signal to the terminal equipment 2 and selects a specific channel while the multi-channel is being screened, the corresponding channel through the connected session. In this mode, the quality of a specific channel is increased.

In the multi-channel switching mode during the normal channel screening, the channel currently being screened when the scalability distribution server 19 transmits the general channel signal to the terminal device 2 and the multi-channel guide mode is set by the terminal device 2 is displayed. This mode finds and processes sessions in a multi-channel guide.

Here, looking at the control method of the second embodiment of the system of the present invention ,

First, as shown in FIG. 8, the process proceeds to step S200 of checking the terminal equipment setting signal in the initial state S100, and the scalability distribution server checks whether the mode setting signal is received from the terminal equipment through the base station system unit.

At this time, if the mode setting signal is received from the terminal equipment as a result of the terminal equipment setting signal checking step (S200), the process proceeds to the mode setting signal processing step (S300) and the scalability distribution server requests the terminal equipment. The current mode is changed by adjusting the condition of the scalability and the quality of the screen with the channel signals received from the channel server according to the mode signal.

In addition, if a mode change signal is input from the terminal equipment after the mode setting signal processing step (S300), the mode change execution step (S400) proceeds and the scalability distribution server changes its mode so that the scalability condition and the screen quality are changed. Retransmit the adjusted channel signals to the terminal equipment.

Here, in the mode change execution step (S400), when a specific channel is selected from the terminal equipment while providing the multi-channel guide signal, the scalability distribution server connects the specific channel to the terminal equipment. It further includes a specific channel selection mode step of multi-channel transmission to increase the quality (or resolution) of the.

In the mode change execution step (S400), when the multi-channel guide mode is set by the terminal equipment while transmitting the general channel signal to the terminal equipment, the scalability distribution server searches for the channel currently being screened in the multi-channel guide and performs session processing. It further comprises a multi-channel switching mode step during the channel screening.

In other words, the scalability distribution server 19 of the multi-channel system unit 14 of the radio access network system 3 first transmits the DMB channel signal from the terminal equipment 2 through the base station system unit 13. When requested, a plurality of channel servers 15a-n generate and process content channel signals for DMB such as dramas, news, cartoons, music, and movies for each server, and then encode them to the scalability distribution server 19. Output it.

At this time, the scalability distribution server 19 receives the channel signals from the channel server 15a-n according to the mode signal requested by the terminal equipment 2 to adjust the condition of scalability and the quality (or resolution) of the screen. When the terminal equipment 2 requests the screening of the normal channel, the terminal device 2 executes the normal channel screening mode.

That is, the scalability distribution server 19 receives data of a degree of scalability that the terminal equipment can receive only from a specific server selected by the terminal equipment 1 among the channel servers 15a-n. By transmitting the minimum scalability data and the enough detail data to the terminal equipment 2 for the remaining channel data through the session connected to 2), one on the display unit 1 of the terminal equipment 2 Only channel data is displayed to have an optimum quality (or resolution).

On the other hand, the scalability distribution server 19 executes the multichannel screening mode when the terminal equipment 2 requests the multichannel screening. In this case, the scalability distribution server 19 includes a plurality of channel servers 15a. -n) receive the encoded channel signals with the minimum scalability and process them as multi-channel guide screens, and process the processed multi-channel guide signals as one channel to the terminal equipment (2) requesting the DMB signal. It transmits via the base station system part 13, the satellite 11, or the transmission tower 12.

At this time, the DMB signal processing unit 4 of the terminal equipment 2 processes the multi-channel guide signal transmitted from the radio access network system 3 under the function control of the main controller 5 of the terminal equipment 2 to display the display unit 1. ) Then, the main control unit 5 displays the matrix screen composition ratio of the display unit 1 in which the multi-channel guide signal is implemented according to the multi-channel guide signal, that is, a plurality of channel signals are displayed on one screen. Set to display accordingly.

For example, the matrix screen of the display unit 1 implemented according to the multi-channel guide signal of the DMB, as shown in (a) and (b) of FIG. , 3x3, 4x4 ...).

Here, since the sessions are separately connected between the respective channels displayed on the display unit 1 of the scalability distribution server 19 and the terminal equipment 2 of the present invention, the quality of the cell of each channel ( Alternatively, the scalability distribution server 19 may be added or subtracted to individually control the resolution.

On the other hand, during the DMB display process, the user of the terminal equipment 2 sends a mode change signal via the base station system unit 13 of the radio access network system 3 to the multi-channel system unit 14 of the radio access network system 3. When transmitting to the scalability distribution server 19 of the scalability distribution server 19 is a multi-channel selected by a specific channel from the terminal equipment while the mode change signal provides a multi-channel guide signal to show the multi-channel In the specific channel selection mode during use, the transmission process is performed by increasing the quality (or resolution) of the specific channel through the connected session to the terminal device 2 through the transmission path.

In this case, the terminal device user maintains the minimum scalability data corresponding to the desired channel signal and its connected session, terminates the sessions for the remaining channels, and then connects the detailed data session of the desired channel. Increase the quality (or resolution) of the channel. That is, the data other than the desired channel is replaced with the detailed data of the desired channel.

On the other hand, the scalability distribution server 19 is currently being screened through the transmission path when the mode change signal is a multichannel switching mode of the normal channel screening in which the multichannel guide mode is set by the terminal equipment after transmitting the general channel signal. Find a channel in the multi-channel guide and process it.

That is, the scalability distribution server 19 terminates all sessions when there are no channels currently displayed in the channel list provided by the multi-channel guide, and connects the session with the minimum scalability corresponding to the channel list provided by the multi-channel guide. do.
