For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings, in which:
Figure 1 is a block diagram showing the configuration of a mobile video system; Figure 2 shows the configuration of a mobile computing system; Figure 3 is a block diagram showing the configuration of a software platform of a mobile communication terminal according to an embodiment of the present invention; and Figure 4 is a block diagram showing the configuration of a mobile communication terminal according to an embodiment of the present invention.
Referring to Figure 1, a mobile video system based on H.324 and H.323 standards includes audio and video codecs and 110, a multiplexer/demultiplexer (MUX/DEMUX) 120, a system controller 130, a modem 140 and a radio frequency (R/F) interface 150.
An audio signal input via a mike 170 or a video signal input through a camera 174 is converted to digital data and compressed by the audio or video codec 100 or 110. The compressed digital audio and video data is time division multipl-exed by the MUX/DEMUX 120, and then transmitted to another system via the mobile modem 140, the R/F interface 150 and an antenna 160. Meanwhile, video and audio data input via the antenna 160, the R/F interface 150 and the mobile modem 140 is divided into digital video and audio data, by the MUX/DEMUX 120. Then, the digital video data is restored to a video signal by the video codec 110 and displayed on a monitor 176, and the digital audio data is restored to an audio signal by the audio codec 100 and output through a speaker 172.
The system controller 130 has system software including a protocol stack, and controls the operation of the audio and video codecs 100 and 110, the MUX/DEMUX 120 and the mobile modem 140.
Referring to Figure 2, a mobile computing system has the following structure. A server system 200 installed in an office or home and several terminal systems 210, 220 and 230 are interconnected with wires to form a LAN.
Here, connecting equipment 202 for wireless communications is also provided to the LAN or the server system 200. A user can use a mobile terminal (e.g., a notebook computer, etc.) 240 with connecting equipment 242 for wireless communications in areas other than the office or home by connecting the mobile terminal to the LAN. In this case, the mobile terminal is same as any other network computer system provided with a general operating system, except that it is connected to the LAN by the wireless system instead of by cables.
Referring to Figure 3, a software platform of the mobile communication terminal according to an embodiment of the invention is shown. The terminal has a wireless connection to the server system, and is comprised of a web browser management unit 300, a real time operating system 310, a network application program virtual machine 320 and a power save management unit 330.
The web browser management unit 300 generates and manages a graphic user interface for displaying the index of services provided by a server system. The graphic user interface displays services provided by the server system, as a document written in a hyper text markup language (HTML) or hyper dynamic markup language (HDML), enabling a user to select one of the services.
The real time operating system 310 manages an application program for processing video and audio data provided by the server system, and includes a real time processing kernel 312, a network management unit 314, an input/output management unit 316 and a file management unit 318. The real time processing kernel 312 manages tasks by non-preemptive task scheduling. The network management unit 314 manages a network protocol stack including a point to point protocol (PPP), a transmission control protocol /internet protocol (TCP/IP) and a user datagram protocol/internet protocol (UDP). The input/output management unit 316 manages data input and output to an input/output device of a mobile communication terminal by interrupt and DMA control, and includes an input/output library for keyboard input and LCD/VGA display. The file management unit 318 manages the storage of data in a storage unit installed in the mobile communication terminal, and manages searching for the data stored in the storage unit. The file management unit 318 8 supports searching, opening, reading and writing of the files stored in the storage unit. The file management unit 318 also supports searching, opening, reading and writing of files stored in a remote computer system, by 5 access through the network management unit 314.
The network application program virtual machine 320 receives support from the network management unit 314, the input/output management unit 316 and the file management unit 318, and executes network application programs provided by the server system. Here, it is preferable that the network application program virtual machine 320 is a Java virtual machine, and that the network application programs are Java applets.
The power save management unit 330 minimizes power consumption by operating only hardware for watching calls from an external system when no other functions are in progress.
A menu, which is provided by a service provider using the server system and can be selected by a user on the graphic user interface, includes the following three types of services.
First, document-based data services (e.g., news, electronic mail, weather forecast, stock information, etc.) are included. At this time, the server system of the service provider transforms web site information filtered in advance into an HTML/HML document suitable for a display in the remote mobile communication terminal, and then transmits the transformed document. The above transmitted document is parsed by the web browser management unit 300 via the network management unit 314 of the mobile communication terminal, and then the parsed document is displayed.
Second, native services, which are performed only in the mobile communication terminal not in a general network computer, are included. Such services include videoconferencing, an internet phone, and a discriminated service provided by the service provider to the mobile communication terminal. If a user requests the above services, the server system of the service provider transmits the necessary software code to the mobile communication terminal. The software transmitted to the mobile communication terminal is performed by the real time operating system 310 excluding the network application program virtual machine 320. Therefore, the mobile communication terminal performs a service terminal function such as the video conference or the internet phone.
Third, services performed in a network computer and written as Java applets, (e.g., a wordprocessor, a personal information manager, games, etc.) are included. If a user selects the above service from the indexed graphic user interface menu of the mobile communication terminal, the server system of the service provider transmits a corresponding Java applet. The Java applet transmitted to the mobile communication terminal is executed by an interpreter in the Java virtual machine.
Referring to Figure 4, a mobile communication terminal according to an embodiment of the present invention includes a main processing unit 400, a R/F communication unit 410, an input unit 420, a video output unit 430 and an audio input/output unit 440.
The main processing unit 400 is comprised of a microprocessor 402 and a main memory 404 forstoring programs and data to be processed by the microprocessor 402. In the mobile communication terminal the main processing unit 400 mounts the software platform of Figure 3, and executes application programs and network application programs, each for processing video and audio data, downloaded from the server system. Thus, the main processing unit 400 requires a microprocessor, that is smaller than that of the mobile terminal 240 in the mobile computing system of Figure 2, and a main memory having smaller capacity.
The R/F communication unit 410 connected to the main processing unit 400 includes a wireless modem 412 and an antenna 414, and communicates with a server system by wireless communication.
The input unit 420 connected to the main processing unit 400 receives instructions from a user and includes a keyboard 422 and a mouse 424.
The video output unit 430 outputs video data processed by the main processing unit 400. In the mobile communication terminal, it is preferable that the video output unit 430 includes a LCD display 432 to reduce its volume. A video codec 434 for processing video data such as a video conference, etc., is also included in the video output unit 430 together with the LCD display 432.
The audio input/output unit 440 includes a mike 444 for receiving sound from a user, a speaker 446 for outputting sound, and an audio codec 442 for converting an audio signal to digital audio data or converting digital audio data received from the main processing unit 400 to an audio signal.
The mobile communication terminal can execute user application programs received from a network, as well as perform functions provided by an existing mobile video phone, by restrictedly combining the open system architecture of a wireless network computing system with the mobile video phone. Thus, a small, economic mobile communication terminal can be realized.
