The mobile terminal developed simply for the purpose of communication has been advanced to support various functions according to the needs of consumers, and as a basic method for supporting various functions, a virtual machine has been mounted on the mobile terminal.

In a mobile communication terminal such as a mobile phone, a virtual machine (VM) plays a role of an operating system. In general, an application program of a mobile communication terminal refers to programs running on such a virtual machine (VM) base. For example, each mobile service such as game, mobile banking, and mobile securities is made of one program that is executed in a virtual machine (VM), and one program is installed and run in the virtual machine (VM).

On the other hand, most of the mobile content that is widely used now is focused on entertainment such as games. In the case of games, the program itself is not frequently upgraded or the service is continuously changed. On the other hand, in case of mobile contents that provide continuous services such as mobile banking and securities, functions are expanded and changed more frequently. Therefore, every time user upgrades, the terminal user must download and install the entire program again or install A / S center. There is inconvenience to visit.

Accordingly, an object of the present invention is to provide a method for automatically upgrading an internal software program or a content program and data in a mobile communication terminal capable of receiving Digital Multimedia Broadcasting without user intervention.

Upgrading the old version of the program or data using the read data stream for upgrading the terminal;

Furthermore, waking up the DMB module in response to receiving the upgrade command;

And switching the DMB module to the sleep mode after the upgrade is completed.

In such embodiments, the upgrade command is input in the form of an SMS message.

According to the above-described feature of the present invention, the terminal receiving the upgrade command through the SMS message is able to automatically upgrade the corresponding software program by receiving the terminal upgrade data stream propagated through the DMB module and the designated channel.

Therefore, the terminal user can conveniently upgrade the terminal software and the like without any additional action for upgrading the software.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 illustrates a block configuration of a mobile communication terminal capable of receiving DMB broadcasting according to an embodiment of the present invention.

As shown in FIG. 1, a mobile communication terminal capable of receiving a DMB broadcast includes a DMB module 100 for receiving and processing a DMB broadcast and a phone module for conducting a mobile call.

The tuner 105 constituting the DMB module 100 tunes and outputs only an RF signal of a specific channel selected by the controller 210 among the RF signals received from the antenna ANT1. This tuner 105 basically has a frequency conversion function.

The DMB processor 110 in the DMB module 100 is responsible for demodulating and decoding the DMB signal output from the tuner 105. That is, the DMB processor 110 demodulates the DMB signal received through the tuner 105 and separates the audio signal, the video signal, and the upgrade data stream from the demodulated DMB signal and decodes each channel. The decoded DMB signal for each channel is stored in the memory 1 115, which is a buffer memory.

The codec 120 in the DMB module 100 decodes an audio signal and a video signal received separately from the DMB processor 110 into a signal of MPEG standard, and outputs them to different channels. That is, the decoded audio signal is output to the audio processor 215 of the phone module to be described later, and the decoded video signal is output to the image processor 130 to be described later. The memory 2 125 connected to the codec 120 is used to store the decoded audio signal and the video signal.

The image processor 130 in the DMB module 100 processes image signals output from the codec 120 and user data output from the controller 210 to be described later and outputs them to the corresponding areas of the display unit 230.

The display unit 230 displays the data output from the control unit 210 in the communication mode, and displays the DMB image data output from the image processing unit 130 in the DMB mode.

For reference, the tuner in the DMB module 100 may include a tuner for satellite broadcast reception and a tuner for terrestrial broadcast reception, respectively.

Meanwhile, the configuration of the phone module will be described in detail. The RF unit 200 includes an RF transmitter for upconverting and amplifying a frequency of a transmitted signal, and an RF receiver for low noise amplifying and downconverting a received signal.

The data processor 205 includes a transmitter for encoding and modulating a transmitted signal and a receiver for demodulating and decoding a received signal. The data processor 205 may be configured of a modem and a codec.

The controller 210 controls the overall operation of the mobile communication terminal. For example, if the SMS message received through the data processing unit 205 is a message indicating the software upgrade, the channel of the tuner 105 is changed and set based on the channel information included in the message, and received through the changed set channel. It plays a role of upgrading the corresponding software with stream data for terminal upgrade read from the broadcast stream.

The audio processor 215 reproduces a received audio signal output from the data processor 205 or transmits a transmission audio signal generated from a microphone to the data processor 205. In addition, the audio processor 215 plays a role of reproducing and outputting an audio signal of the DMB signal output from the codec 120 in the DMB mode.

Program data for controlling the mobile communication terminal, software program data and content data for implementing various additional functions are stored and managed in the memory 3 220. For reference, the memory model 220 stores and manages terminal model identification information necessary for reading the terminal upgrade data stream.

The key input unit 225 includes a plurality of numeric keys and function keys, and generates key data according to each key press and outputs the generated key data to the controller 210.

Hereinafter, a method of automatically upgrading terminal software in a mobile communication terminal capable of receiving DMB broadcasting having the above-described configuration will be described in detail.

First, FIG. 2 illustrates a flowchart of a terminal software automatic upgrade process according to an embodiment of the present invention, and FIG. 3 illustrates a transport stream format for explaining an embodiment of the present invention.

Referring to FIG. 2, first, a person who wants to use the automatic terminal upgrade service requests the service provider or a content provider. Terminal users who applied for the service can receive the terminal software automatic upgrade service by the following method.

First, the carrier or the content provider transmits an SMS message containing the upgraded order and channel information contracted to the service applicant's terminals. The "channel information" means a broadcast channel through which a terminal upgrade data stream is transmitted.

The SMS message is applied to the control unit 210 through the RF unit 200 and the data processing unit 205 of the terminal. If the reception of the SMS message is received, the controller 210 determines whether the message includes the upgrade command and the channel information contracted thereto (step S1). If the determined upgrade command and channel information exist, the controller 210 determines whether the DMB module 100 is a wake-up (DMB mode). If it is not up, it wakes up the DMB module 100 (step S2). The channel of the DMB module 100 which has been woken up according to the channel information included in the command is changed and set according to the received channel information (step S3).

Meanwhile, the DMB broadcasting center inserts a terminal upgrade data stream requested by a communication company or a content provider into a general broadcast transport stream and transmits the same, but transmits it through a contracted channel at a contracted time period.

As such, the broadcast transport stream transmitted from the DMB broadcasting center is received through the tuner 105 and applied to the DMB processor 110, and the DMB processor 110 separates the terminal upgrade data stream and outputs it to the controller 210. do.

Accordingly, the controller 210 determines whether the separated data stream is a data stream for upgrading the terminal (S4). The determination method may be determined through PID information located in the transport stream packet header as shown in FIG. 3. The PID information serves as a delimiter for distinguishing the contents of the stream. As shown in FIG. 4, if a value between 0x0010 and 0x1FFe is assigned as the terminal model identifier, the payload data section is compared through the comparison of the terminal model identifier information. It is possible to determine whether the data stream contained in the data stream for upgrading the terminal.

If the stream received in step S4 is found to be an upgrade data stream, the controller 210 reads its own terminal upgrade data stream (step S5) and stores it in the memory 3 220. In addition, by upgrading the old version of the program or data using the read terminal upgrade data stream (step S6), it is possible to conveniently upgrade the terminal software through the DMB broadcast reception without user intervention.

If the DMB module 100 in the sleep mode is upgraded by waking up, the power consumption may be minimized by switching the DMB module 100 back to the sleep mode after the upgrade is completed.

As described above, according to the present invention, since the terminal receiving the upgrade command through the SMS message can receive the terminal upgrade data stream propagated through the DMB module and the designated channel, the terminal can automatically upgrade the corresponding software program. There is an advantage in that the terminal software can be upgraded conveniently without any additional action for upgrading.

On the other hand, the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
