TECHNICAL FOR CONTROLLING OPERATION OF MOBILE TERMINAL CAPABLE OF HIGH DATA RATE SERVICE}

The present invention relates to a mobile communication terminal, and more particularly, to an operation control method in a mobile communication terminal capable of a high data rate service.

These days, some mobile operators are preparing for high-speed data rates (HDR) services that can improve the quality of high-speed wireless Internet services when linked with cdma (code division multiple access) 2000 1x. This is because the HDR service does not support a separate voice service, but instead has an excellent data transmission capability that exceeds the existing wired high-speed Internet service.

The cdma2000-1x Evolution Data Only (EVDO) service, which is referred to as ultra-high-speed wireless data communication using the second generation network, has 10 times the transmission speed of cdma2000-1x (IS95C), which is called 2.5 generation. It has been classified as a synchronous International Mobile Telecommunication (IMT) -2000 (3G: 3rd Generation) technology. HDR service provides data rates of up to 2.4 Mbps and up to 153.6 Kbps backward by allocating dedicated data channels, making it a good choice for high-speed wireless Internet services. HDR services can be used to enhance data transfer capabilities within existing cdma2000-1x (IS95C) networks or individual data networks. In existing CDMA networks, some channels change from voice to data. However, the HDR service uses a combination of time division multiplexing (TDM) and CDMA to share each channel with multiple users, but does not have a fixed time band as in time division multiple access (TDMA), but only when needed. Take Optimized for Internet Protocol (IP) packets and Internet access, HDR's data rate will vary depending on the distance from the mobile terminal to the base station.

Accordingly, the mobile communication terminal supporting the EVDO service can service at a data transmission speed of 2Mbps or more that exceeds the wired high-speed Internet, and can transmit and receive video in real time. The mobile communication terminal uses a spatial diversity scheme employing two first and second antennas and configures two first and second wireless receivers to minimize the loss of received information due to fading. In this case, the first antenna and the first wireless receiver are correspondingly connected, and the second antenna and the second wireless receiver are correspondingly connected. Here, the first wireless receiver receives voice data, low speed and high speed data, and the second wireless receiver receives high speed data together with the first wireless receiver when using the HDR service.

However, the mobile communication terminal has increased battery power by using two antennas and two wireless receivers together, and loads of hardware and software for various control related to the two wireless receivers are increased.

Accordingly, an object of the present invention is to provide a terminal operation control method for reducing battery power consumption in a mobile communication terminal capable of a high speed data communication service.

Another object of the present invention is to provide a method for controlling a terminal operation that can reduce load of hardware and software for battery power consumption and various controls related to two wireless receivers in a mobile communication terminal capable of a high speed data communication service.

In accordance with the above object, the present invention, the first, the second antenna, and a first wireless unit connected to the first antenna and having a wireless transmitter and a wireless receiver, and a second wireless receiver connected to the second antenna A method of controlling an operation in a folding mobile terminal comprising a main body and a sub body, wherein the mobile communication terminal is connected to an external terminal. Determining whether the sub-body is open; and, if the sub-body is not open, making a query to determine whether the sub-body is open for a high-speed data rate service, and receiving a response from the external terminal according to the query. If at least one of the subbody openings is present, the first wireless unit and the second wireless unit are supplied with battery power, and the first and second non- Performing sub-related signal processing; determining if the current mode state of the mobile communication terminal is a traffic mode of a high speed data rate service if there is no response from the external terminal; and traffic of the high speed data rate service. In the mode, the battery power is supplied together with the first wireless unit and the second wireless unit, and the first and second wireless unit related signal processing are performed, and if the traffic mode is not the high speed data rate service, the second wireless unit is performed. It is characterized in that it comprises a process of cutting off the battery power of the radio unit, and performs a signal processing related to the first radio unit.

2 is a control flowchart of a mobile communication terminal according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a block diagram of a mobile communication terminal according to an embodiment of the present invention, in which two antennas and two wireless receivers employing a space diversity scheme for high-speed data rates (HDR) services are shown. An example of a mobile communication terminal in use. In FIG. 1, the first antenna ANT1 of the two antennas ANT1 and 2 is an antenna mounted on the main body of the mobile communication terminal, and is a non-directional retractable that meets the purpose of bidirectional communication and easy portability. Antenna type is suitable. Among the two antennas ANT1 and 2, the second antenna ANT2 is a detachable antenna of the mobile communication terminal, and together with the first antenna ANT1 to minimize loss of received information due to signal fading, high-speed data rates (HDR) Will be used in service. Accordingly, the second antenna ANT2 has a planar antenna structure such as Planar Inverted F Antenna (PIFA) or a chip antenna structure of SMD (Surface Mounted Device) in order to avoid protruding from the upper portion of the terminal body. In addition, the second antenna ANT2 preferably comprises an antenna structure using a transmission line for connecting to an external terminal, an antenna structure using earphones, or an antenna structure using accessories. Considering the limitations of the terminal size and terminal design according to the trend of the mobile communication terminal, and difficulty in selecting the location of the second antenna ANT2, it is preferable that the mobile terminal is detachable when the HDR service is not provided.

The first radio unit 10 includes a duplexer 12 connected to the first antenna ANT1, and a radio transceiver 14, and under the control of the control unit 24, not only voice data but also low speed and high speed data (circuit) Data and packet data). The second radio unit 16 includes an antenna connection unit 18 connected to the second antenna ANT2 and a dedicated radio receiver 20, and only voice data applied through the second antenna ANT2 under the control of the control unit 24. It also receives low speed and high speed data (circuit data, packet data).

The antenna connection unit 18 included in the second radio unit 16 allows the second antenna ANT2 to be connected to the dedicated radio receiver 20 by the user's installation of the second antenna ANT2 or antenna connection. Accordingly, the antenna connection detecting unit 22 detects that the detachable second antenna ANT2 is connected to the dedicated wireless receiving unit 20 and applies it to the control unit 24.

The controller 24 performs an overall control operation of the mobile communication terminal. In particular, according to an embodiment of the present invention, the control unit 24 determines whether the second antenna ANT2 is connected for the high speed data transmission (HDR) service and whether the external terminal is connected, and the mobile terminal is the high speed data transmission (HDR) service. Depending on whether the traffic mode for the control, the switch 36 is controlled to supply or cut off the battery power BATT applied from the battery power source 34 to the dedicated wireless receiving unit 20 of the second wireless unit 16.

That is, the controller 24 supplies the battery power BATT of the battery power source 34 to the dedicated wireless receiver 20 through the switch 36 when the mobile communication terminal is in a traffic mode for a high speed data transfer (HDR) service. On the other hand, the switch 36 is turned on. On the other hand, the controller 24 controls the battery power of the battery power supply 34 if the mobile communication terminal is not in a traffic mode for a high speed data transfer (HDR) service. The switch 36 is turned off so that the BATT is not supplied to the dedicated wireless receiver 20 through the switch 36. The battery power supply 34 switches the battery power BATT through the switch 36 in a second manner. The wireless unit 16 is supplied to the dedicated wireless receiver 20, and the wireless transceiver 10 of the first wireless unit 10 is directly supplied without any switch. The battery power BATT of the battery power supply unit 34 is supplied to other circuit units other than the wireless radio receiver 14 of the first radio unit 10 and the dedicated radio receiver 20 of the second radio unit 16. FIG. 1 illustrates only the battery power BATT supplied to the wireless transmitter / receiver 14 of the first wireless unit 10 and the dedicated wireless receiver 20 of the second wireless unit 16 to help understand the description of the present invention. Should be understood.

The external terminal interface 26 performs an interface with an external terminal such as a personal computer. The external terminal interface 26 may be a device that supports protocols such as a universal asynchronous receiver / transmitter (UART), a universal serial bus (USB), an infrared data association (IrDA), and a Bluetooth. The display unit 28 displays various messages and the like under the control of the control unit 24. The key input unit 30 includes a plurality of numeric keys and function keys, and outputs key input data corresponding to a key pressed by the user to the controller 24. The key input unit 30 includes a key for HDR service according to an embodiment of the present invention. The key for the HDR service may be implemented as a key dedicated to the HDR service separately provided, or may be implemented using a key using a function key. The memory unit 31 includes program data necessary for controlling the operation of the mobile terminal and a data memory for storing data generated during the operation control of the control unit 24 or during the operation performed by the user's request. The voice processing unit 32 converts the voice data among the data received from the first radio unit 10 into an audible sound through a speaker SPK under the control of the control unit 24, and is received from the microphone MIC. The audio signal is converted into data and output to the first radio unit 10.

In an embodiment of the present invention, when a user inputs a key for HDR service for HDR service, two reception paths are used together to accurately receive high-speed data. In other words, the controller 24 receives the corresponding key input data of the HDR service key input through the key input unit 30, and controls the switch 36 to be turned on according to the received key input data. As a result, the battery power BATT of the battery power supply 34 is supplied to the dedicated wireless receiving unit 20 through the switch 36. Thus, the battery power is supplied to the first wireless unit 10 and the second wireless unit 16 together. The BATT is supplied, and signal processing associated with the first and second radio units 10 and 16 is performed. As a result, a spatial diversity scheme using two antennas ANT1 and 2 can increase the reception rate of high-speed data. In the absence of a user's key input for the HDR service, the mobile communication terminal uses two reception paths together to accurately receive the received signal only when the mobile communication terminal is in the traffic mode for the HDR service. If the mode is not the sleep mode (idle mode), idle mode (idle mode), traffic mode for voice calls, traffic mode for the low-speed data service, the control unit 24 by turning off the switch 36 The battery power BATT of the power supply unit 34 is not applied to the second wireless unit 16. Accordingly, the battery power BATT is applied only to the first radio unit 10. As a result, the mobile communication terminal can reduce the load of the software as much as not performing signal processing related to the second radio unit 16, and can reduce the battery power as much as it should supply to the second radio unit 16. .

2 is a control flowchart of a mobile communication terminal according to an embodiment of the present invention.

Referring to Figures 1 and 2 will be described in detail the operation according to the embodiment of the present invention.

The controller 24 checks the current mode of the terminal in step 200 of FIG. 2. Modes in a mobile terminal capable of HDR service include a sleep mode, an idle mode, a traffic mode for a voice call, and a low-speed data service (eg, a transmission rate of 14.4kbps, 64kbps, 154kbps, etc.). And traffic mode for HDR service (transmission rate: up to 2.4 Mbps, up to 153.6 Kbps).

Thereafter, the controller 24 proceeds to step 202 of FIG. 2 to determine whether the current mode of the terminal is the traffic mode for the HDR service. The current mode of the terminal is set by a protocol between the mobile communication terminal and the base station, and each of the mobile communication terminal and the base station recognizes the current mode. If the current mode of the terminal is a traffic mode for HDR service, the controller proceeds to step 208. In step 208, the controller 24 turns on the switch 36 through a control signal to turn on the battery power BATT of the battery power source 34. The first wireless unit 10 and the second wireless unit 16 are supplied to each other, and the first and second wireless units 10 and 16 related signal processing is performed. That is, the control unit 24 turns on the switch 36 to supply the battery power BATT to the first radio unit 10 and the second radio unit 16 together, so that the second radio unit 16 is turned on. The battery power supply BATT of the battery power supply unit 34 is also supplied to the dedicated wireless receiving unit 20. Accordingly, the control unit 24 may increase the reception rate of the high speed data by using the spatial diversity technique using the two antennas ANT1 and 2.

In contrast, in step 202 of FIG. 2, if the current mode of the terminal is not a traffic mode for HDR service, the controller 24 proceeds to step 204 of FIG. 2 and inputs a key for HDR service through the key input unit 30. Judge whether there is. When the user of the mobile communication terminal presses a key for the HDR service provided in the key input unit 30 for the HDR service, key data corresponding to the HDR service is applied from the key input unit 30 to the controller 24. In the determination of step 204 of FIG. 2, if there is a key input for the HDR service from the user, the controller 24 proceeds to step 208 of FIG. 2 to turn on the switch 36 through the control signal, and thus the battery power source 34. Supplies the battery power BATT to the first radio unit 10 and the second radio unit 16, and performs signal processing related to the first and second radio units 10 and 16.

On the other hand, if the traffic mode for the HDR service is not determined in step 202 of FIG. 2, the current mode of the terminal is a sleep mode, an idle mode, a traffic mode for a voice call, and a traffic for a low speed data service. After that, if there is no key input for the HDR service of step 204 of FIG. 2, the control unit 24 proceeds to step 206 of FIG. 2 and dedicates the radio of the second wireless unit 16. The power supply of the receiver 20 is cut off and the signal processing associated with the first radio unit 10 is performed. That is, the controller 24 turns off the switch 36 so that the battery power BATT of the battery power source 34 is not applied to the dedicated wireless receiver 20 of the second wireless unit 16. Therefore, when the traffic mode is not for the HDR service, the battery power BATT is not supplied to the second wireless unit 16, and battery power is supplied only to the first wireless unit 10. As a result, the load of the software of the control unit 24 can be reduced as much as not performing signal processing related to the second radio unit 16, and the battery power as much as the power to be supplied to the second radio unit 16 can be reduced. have.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

As described above, the present invention provides battery power consumption in a mobile communication terminal capable of high-speed data communication service by selectively supplying battery power and performing wireless signal processing corresponding to a user's request for HDR service using a key. It reduces the load on hardware and software for various control related to the two wireless receivers.
