Hereinafter, the present invention having the above-described configuration will be described in detail with reference to the accompanying drawings of an apparatus for controlling an Aldypi of a mobile terminal through a virtual channel.

The mobile communication system communicates by using a multimedia signal including a video signal due to the development of a corresponding technology. When the communication is not performed, the mobile communication system can enjoy the video data signal recorded and stored in the server 400.

The server 400 is a device constituting a mobile communication system, and is generally installed and operated at a position similar to a mobile switching center (MSC). The server 400 stores image data signals and transmits them to the corresponding control command signals of the mobile terminal. It outputs the data and compresses it by RDP technology and transmits it as packet data by TSI piapi.

The image data signal is recorded and stored in the application unit 410 constituting the server 400, and the virtual channel manager 420 analyzes a control command signal applied from the mobile terminal 100, and the application unit 410. Control the video data signal output.

The portable terminal 100 inputs a command signal for controlling its own function in the local application unit 150 and simultaneously outputs a control command signal for controlling the output of the image data signal of the server.

For example, when the local application unit 150 outputs a control command signal for controlling the server 400 to output an image data signal, the Aldi session management unit 134 constituting the Aldi skin 130. Manages an AldiPy path with the server 400 to be established, and when the mobile terminal 100 leaves the service area of the mobile communication system, the AldiPy path is disconnected. Manage to reset.

When the RDP path (SESSION) is set as described above, the virtual channel manager 132 is controlled to set the virtual channel (VIRTUAL CHANNEL), and sends a signal for requesting the server 400 to drive the virtual channel. send.

As described above, since the signal output from the RPD 130 is applied to the TSI PII 110 through the RPD terminal unit 120, the signal is converted into a packet data signal in which a transmission destination address signal and a sequence number are recorded and communicated. Via the path 200 is applied to the tsipiapi skin 440 of the server 400.

Since the TSI PIP 440 detects a corresponding control signal including a control command signal and applies the control signal to the terminal unit 430, the RDP driver 432 analyzes an RDP path setting control signal to determine an RDP path. In this case, the result of setting the RDI path as described above is displayed at the designated position of the display unit 140.

The control command signal for requesting the virtual channel (VIRTUAL CHANNEL) is applied to the virtual channel manager 420 to drive the virtual channel, and is displayed at a designated position of the display unit 140.

As described above, in the state where an AldiP path is set between the portable terminal 100 and the server 400 and the virtual channel is driven, a request for outputting a video signal from the local application unit 150 of the portable terminal 100 is performed. When the control command signal is transmitted through the virtual channel, the virtual channel manager 420 of the server 400 analyzes and controls the application unit 410.

The application unit 410, which receives the control command signal from the virtual channel manager 420, outputs a corresponding video data signal, and the image signal output from the application unit 410 is an RDP driver of the terminal unit 430 ( The image data signal compressed by 432 and compressed as described above is applied to the device driver 434 to be converted into an appropriate level signal and output.

As described above, the compressed image data signal output from the terminal unit 430 is applied to the TSI 440 and is converted into a packet data signal to which a transmission destination address and a corresponding serial number are added, and the MSC The base station (BS) is transmitted to the tsipia skin 110 of the mobile terminal 100 through the communication path 200 is included.

The TSI pipi 110 receives and detects a signal converted into packet data, and outputs the compressed video data signal to the RDP terminal 120 as a compressed image data signal in the corresponding order. Decompresses and outputs the compressed video data signal.

As described above, the decompressed and output image data signal is applied to the display unit 140 through the RPD 130 so that the image data signal is visually displayed.

The RPD session managing unit 134 of the RDP 130 also adjusts the size of the window displayed on the display unit 140 and also controls the visibility of the displayed video signal.

As described above, when the mobile terminal 100 receives the image data signal transmitted through the AldiP path, and wants to stop receiving the image data signal, the corresponding control command is transmitted through the local application unit 150. When the signal is output, the virtual channel is transmitted to the virtual channel manager 420 of the server through the virtual channel driven by the virtual channel manager 132 of the RDP 130.

The virtual channel manager 420 analyzes a control command signal applied through the virtual channel and stops output of the image data signal from the application unit 410, so that the display unit 140 of the mobile terminal 100 is used. The display of the video signal is stopped and the execution result of the control command is displayed at the designated position of the display unit 140.

Therefore, there is an advantage in controlling the video data signal of the server directly in the mobile terminal with limited functionality and limited processing capacity.

Hereinafter, with reference to the accompanying Figure 4, by way of the present invention, a method for controlling an Aldypie of a mobile terminal via a virtual channel will be described.

The virtual channel manager 420 of the server 400 operates in preparation for driving the virtual channel (S100), and the RD skin 130 of the mobile terminal 100 is connected to the server through the RPD session manager 134. In step S110, an RDP path is set with the 400.

The AldiP path set as described above determines whether or not the AldiPy path is disconnected from the service area of the mobile communication system by the mobility of the mobile terminal 100 (S120). In step S110, the RDP path is reset, and when the RDP path setting is maintained, the mobile terminal 100 drives the virtual channel and the server 400 drives the virtual channel having the same contents. Request (S130).

When the RDP path is released in step S130, the server 400 that receives a virtual channel driving request to stop driving together drives the virtual channel having the same content as that of the mobile terminal 100, and the RDP path. It is determined whether is set (S140), and it is determined whether the control command of the mobile terminal 100 is applied through the virtual channel driven as described above (S150).

When the control command is received through the virtual channel from the mobile terminal 100 in the determination (S150), the server 400 analyzes the control command through the virtual channel manager 420 and executes the analyzed control command. (S160).

Since the result of the control command executed as described above is notified to the portable terminal 100 through the driven virtual channel (S170), the portable terminal 100 displays the execution result of the control command at a designated position of the display unit 140. Check to confirm.
