BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile terminal and a wireless LAN, and in particular, a mobile terminal of a code division multiple access (CDMA) method that mainly uses voice and low-speed wireless data (144Kbps or less), and a wireless LAN according to the IEEE802.11b standard. The present invention relates to a mobile terminal and an integrated terminal device of a wireless LAN, which are suitable for performing high-speed wireless Internet and voice calls by integrating a network (WLAN).

In general, a communication system is a system that performs information processing by combining a terminal with a remote communication line, and there are wired and wireless communication systems. The wireless communication system is a communication system for mobile devices such as people, cars, ships, trains and aircraft, including mobile phones (mobile phones, vehicle phones), port phones, aircraft phones, mobile public phones (trains, cruise ships, Installed on express buses, radio calls, radiotelephones, satellite communications, amateur radio, and fishing service ships.

These communication systems include the AMPS (Advanced Mobile Phone Service) system using analog methods, CDMA and TDMA (Time Division Multiple Access) systems using digital methods, and Frequency Division Multiple Access (FDMA) systems. System, WLL (Wireless Local Loop) system, and the like.

1 is a block diagram of a conventional CDMA mobile terminal.

The CDMA mobile terminal wirelessly accesses voice data information to a public switching telephone network (PSTN) and the Internet network through a method of transmitting / receiving from a frequency resource of a designated frequency band between the base station and the mobile terminal.

1, a CDMA mobile terminal has a frequency bandwidth according to a forward / reverse carrier frequency and a chip rate defined in a corresponding system, and typically has a frequency bandwidth of 1.2288 MHz.

In order to overcome the multipath fading, the mobile terminal includes a receiver receiver structure in a modem, and the receiver circuit includes an intermediate frequency (IF) and a radio frequency (RF) for controlling CDMA power. Gain control).

2 is a block diagram of a conventional WLAN PC card.

Thus, WLAN is a network structure having a transmission rate of 11 Mbps in the IEEE802.11b standard based on Transmission Control Protocol / Internet Protocol (TCP / IP).

Therefore, DSSS (Direct Sequence Spread) in the Industrial Scientific Medical (ISM) band (2.4 ~ 2.485GHz) in half duplex via Medium Access Controller (MAC) connected to the PCMCIA (Personal Computer Memory Card International Association) interface of the notebook PC. Spectrum) method to transmit information. At this time, the transmission output of each of the WLAN PC card and the access point (AP) is fixed to the channel allocated by the access point (AP) within 10 mW without permission and within 100 mW with permission, so that mobility, portability, Simplicity, speed and flexibility are guaranteed.

The WLAN is basically similar to the transmission / reception circuit of the CDMA mobile terminal, but has a structure in which reception does not operate when performing a transmission operation, and transmission does not operate when performing a reception operation.

Referring to the operation of the conventional device in detail as follows.

The case of a CDMA mobile terminal will be described first with reference to FIG.

The receiving circuit amplifies the base station signal applied to the antenna by a switch (SW) Low Noise Amplifier (LNA) through a duplexer.

The amplified CDMA signal is converted to IF through a down converter (down converter) by removing other band frequencies with an RF SAW filter.

After performing the channel filter with the IF SAW filter, gain control is performed according to the change of the reception level, converted to the baseband signal through the demodulator, and then passed through the baseband lowpass filter to the analog-to-digital converter. Converter, A / D) converts the digital signal and is applied to the DSP (Digital Signal Processor) processing unit, which is commonly referred to as MSM (Mobile Station Modem), and outputs it through a coder-decoder (CODEC).

In addition, the transmitting circuit modulates the data generated by the microphone and the information device in the MSM to convert the CDMA digital information into a baseband analog signal through a digital-to-analog converter (D / A), followed by a modulator and an intermediate frequency gain. The control amplifier varies the level of the transmission signal under control of the base station.

The signal passes through an IF SAW filter, an uplink frequency converter, an image filter rejection filter, and a drive amplifier (AMP) and a power amplifier (PA). The antenna is radiated to the antenna through the duplexer and transmitted to the base station.

Meanwhile, the operation of the WLAN will be described with reference to FIG. 2.

In the receiving circuit, the AP signal applied to the antenna is switched by a switch (Dual SW) to be amplified by the LNA. Frequency components of the amplified WLAN band are converted to IF through a downlink frequency converter by removing other band frequencies with an RF SAW filter.

After performing the channel filter with IF SAW, gain control is performed according to the change of the reception level, converted into a baseband signal through a demodulator, and then converted into a digital signal through a baseband low pass filter.

In addition, it is generally applied to a DSP processing unit called MAC to transmit information data into the PC through the PCMCIA interface.

In addition, the transmitting circuit modulates data generated by an information device such as a PC / PDA (Personal Digital Assistant) in the MAC to convert the WLAN digital information into a baseband analog signal through a digital-to-analog converter. Pass the amplifier to vary the level of the transmitted signal according to the propagation environment.

The variable signal passes through an IF SAW filter and passes through a driving amplifier and a power amplifier via an uplink frequency converter and an image signal removing filter. The antenna is radiated to the antenna through the SAW filter and transmitted to the AP.

However, the conventional CDMA mobile terminal and the wireless LAN card, which have been used independently of each other, have the following problems.

First, in case of CDMA mobile terminal, there was no problem to make voice call. However, when attempting wireless internet, only text mode service outputted through LCD window inside CDMA mobile terminal is provided. It was inconvenient to purchase newly developed separate PCMCIA type CDMA wireless modem and to use it by subscribing to other mobile phone number to CDMA service provider. In this case, an irrational situation occurs in which a plurality of terminals having different telephone numbers of the terminal exist.

In addition, an extension cable is connected to a serial connector or a USB (Universal Serial Bus) port of a laptop to a data connector generally attached to the bottom of a CDMA mobile terminal. In this case, it is connected to the data rate of 144Kbps which is a bit faster than this, so it can be provided with wireless internet service, but it has to use a separate extension cable and the data rate is also low.

In addition, in case of IEEE802.11b wireless LAN, the PCMCIA wireless LAN card is inserted into the notebook to receive 11Mbps transmission speed in the wireless LAN band propagation environment of the AP, but since the CDMA mobile terminal exists separately, the wireless LAN and the mobile terminal can be simultaneously used. If you want to use it has the disadvantage of reducing portability.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems, and an object of the present invention is to integrate a CDMA mobile terminal mainly using voice and low-speed wireless data and a wireless LAN according to the IEEE802.11b standard. It is to provide an integrated terminal device of a mobile terminal and a wireless LAN capable of performing high-speed wireless Internet and voice calls.

In the absence of a wireless LAN AP, the wireless Internet is used, and the high speed wireless LAN is used in an AP installed environment. Configure to be integrated.

The present invention has a method using a wireless LAN card of the PCMCIA type and a method using a USB cable.

Figure 5 is a detailed block diagram of the data interface unit, Figure 5 is a perspective view of the integrated terminal device of the mobile terminal and the wireless LAN implemented by Figure 3, Figure 6 shows the appearance of the integrated terminal device of Figure 5 inserted into a notebook computer FIG. 7 is a diagram illustrating a state in which the integrated terminal device of FIG. 5 is inserted into a PDA, and FIG. 8 is a view illustrating an operation environment of each mode of the integrated terminal device of FIG. 3.

So, CDMA mobile terminal and PCMCIA type wireless LAN card are combined and used for voice call to mobile terminal. In case wireless LAN AP does not exist, insert into PCMCIA slot of notebook and use wireless internet. In the integrated configuration to use a high-speed wireless LAN.

As shown in Figure 5, the main body has a form of a folding terminal on the PCMCIA card, the battery is mounted on the back of the LCD window can be inserted into the notebook, inserted into the notebook and the radio wave environment in the state connected to the AP To be better, the WLAN antenna is arranged at the top of the folder. The CDMA antenna uses a retractable antenna that is commonly used in a terminal. The touchpad disposed in the PCMCIA body uses a membrane-type touchpad to reduce resistance when inserting a notebook.

Further, in order to integrate the circuit of the basic CDMA mobile terminal with the circuit of the WLAN card, a data interface unit 40 for connecting the data of the MSM 10 of the CDMA mobile terminal and the data of the MAC 20 of the WLAN is added. It is connected to the PCMCIA interface unit 30 of the notebook.

In the data interface unit 40, the clock distributor 41 receives a clock and distributes the clock.

The serial / parallel converter 42 receives a clock distributed by the clock distributor 41 and converts serial data into parallel data in the transmission signal transmitted from the MSM 20.

The parallel conversion unit 43 converts the parallel data input from the reception buffers 46 and 47 into serial data and transmits the serial data to the MAC 20.

The transmission buffers 44 and 45 temporarily store the parallel data converted by the serial-to-parallel conversion section 42 according to the control of an input / output write / read (IOWR) control signal.

The inverter 48 phase-inverts the IOWR control signal and outputs it to the control signal input terminal of the reception buffer 46 and 47.

The reception buffers 46 and 47 temporarily store the parallel data input under the control of the phase inverted IOWR control signal output from the inverter 48 so that the parallel and serial converter 43 can read the parallel data.

The operation mode of the integrated terminal device through the PCMCIA can be classified into three types: voice call mode, CDMA data communication mode, and wireless LAN mode.

First, in the voice call mode, a voice call is performed like a general terminal according to the procedure described in the related art through the control of the base station while the circuit portion of the CDMA mobile terminal is operated. At this time, the WLAN circuit portion detects the PCMCIA connection and causes the operation of the WLAN circuit portion to be stopped until it is inserted into the notebook.

Second, the CDMA data communication mode is divided into two again.

One supports text-based wireless Internet, which is currently used on the LCD of the device itself when not connected to a laptop. At this time, the WLAN circuit part maintains a disabled state.

The other is connected to the CDMA base station when inserted into the notebook outside the access area of the WLAN AP so that the data interface 40 of FIG. 3 is in the CDMA data communication mode through the UART 11.

In this case, as shown in FIG. 4, the transmission / reception mode of the CDMA data is determined through IOWR control, and in the transmission mode, the serial transmission data of the UART 11 is transferred from the serial-parallel conversion unit 42 in the data interface unit 40 to the PCMCIA. It converts the data into 16-bit parallel data, which is the reference interface of, and transmits the data to the PCMCIA interface unit 30 through the plurality of transmission buffers 44 and 45.

This is because the state of IOWR is " high " so that transmit buffers 44 and 45 are enabled, and inverter 48 causes receive buffers 46 and 47 to be disabled so that only the transmit portion is operated.

In addition, in the reception mode, the 16-bit parallel data of the PCMCIA interface unit 30 is converted into the reception serial data by the parallel-to-serial conversion unit 43 via the plurality of reception buffers 46 and 47. And the UART 11 of the MSM 10 of the CDMA mobile terminal circuit portion.

This is because the state of the IOWR is " low " so that the transmit buffers 44 and 45 are disabled, and the inverter 48 enables the receive buffers 46 and 47 to operate only the receiving portion.

In this CDMA data communication mode, the control signal of the data interface unit 40 is a signal for determining whether the CDMA data communication mode or the wireless LAN mode is used. When the mobile station moves to the AP access area, the signal is “low” and the CDMA data communication is performed. The mode is placed in the CDMA receive standby state. The CDMA mobile terminal circuit portion is changed to the WLAN mode while maintaining the standby state of the voice call mode.

Third, the WLAN mode refers to a mode that operates when in the AP access area (Infrastructure mode).

It performs data communication with the AP at 11Mbps through the IEEE802.11b wireless LAN access method. At this time, the CDMA mobile terminal circuit part of the integrated terminal device performs normal operation in the voice call mode, and when receiving a voice call from the other party, conducts a voice call using the earphone / microphone jack of the integrated terminal device or executes an application program on the PC. You can make a voice call with the earphone / microphone jack using the sound card function of the notebook.

In addition, the Ad-hoc mode, which is a function embedded in the MAC 20 of the WLAN circuit part, supports one-to-one data communication at high speed when the same integrated terminal device is nearby, as shown in FIG. 8. At this time, the IOWR control signal is maintained in the "low" state, the CDMA data communication mode is disabled, and the voice call mode remains in the standby state.

Meanwhile, FIGS. 9 to 13 illustrate an integrated terminal device using a USB cable, and FIG. 9 is a block diagram of an integrated terminal device of a mobile terminal and a wireless LAN according to another embodiment of the present invention, and FIG. 1 is a perspective view of an integrated terminal device of a mobile terminal and a wireless LAN implemented by FIG. 11 is a view showing the integrated terminal device of FIG. 10 inserted into a notebook computer, and FIG. 12 is a diagram showing the integrated terminal device of FIG. FIG. 13 is a view illustrating an inserted state, and FIG. 13 is a view illustrating an operation environment of each mode of the integrated terminal device of FIG. 9.

Therefore, CDMA mobile terminal and PCMCIA type wireless LAN card are combined and used for voice call to mobile terminal. In case wireless LAN AP does not exist, connect to USB port of laptop with USB cable to use wireless internet. In the installed environment, the integrated configuration to use a high-speed wireless LAN.

As shown in FIG. 10, the basic body has a form of a flip type mobile terminal, and may be implemented in a folder type in some cases.

According to the type and size of the terminal at the bottom, it is equipped with a USB or Mini USB terminal, and it is possible to use a USB cable for a notebook PC or a desktop PC to replace the data connector for the terminal used in the past.

In addition, a wireless LAN antenna is disposed at the top of the wireless terminal to better communicate with a notebook wirelessly connected to the AP. The CDMA antenna may use a retractable antenna generally used in a terminal.

And the MAC of the serial first USB interface unit 12 and the WLAN circuit portion in the MSM 10 of the circuit portion of the CDMA mobile terminal in order to integrate the circuit of the basic CDMA mobile terminal with the circuit of the WLAN card as shown in FIG. 9. The data interface unit 40 for connecting the serial second USB interface unit 21 in the unit 20 is added. The third USB interface 50 connected to the data interface 40 is connected to the notebook computer.

The operation mode of the integrated terminal device using the USB can be classified into three types: voice call mode, CDMA data communication mode, and wireless LAN mode.

First, in the voice call mode, a voice call is performed like a general terminal according to the procedure described in the related art through the control of the base station while the circuit portion of the CDMA mobile terminal is operated. At this time, the WLAN circuit portion detects the USB connection and causes the operation of the WLAN circuit portion to be stopped until it is inserted into the notebook.

Second, the CDMA data communication mode is divided into two again.

One supports text-based wireless Internet, which is currently used on the LCD of the device itself when not connected to a laptop. At this time, the WLAN circuit portion maintains a disabled state.

The other is connected to the CDMA base station when inserted into the notebook outside the access area of the WLAN AP so that the data interface 40 of FIG. 9 enters the CDMA data communication mode through the first USB interface 12.

In this mode, when moving to the AP access area, the CDMA data communication mode becomes the CDMA reception standby state and changes to the WLAN mode.

Third, the WLAN mode refers to a mode that operates when in the AP access area (Infrastructure mode).

It performs data communication with the AP at 11Mbps through the IEEE802.11b wireless LAN access method.

At this time, the CDMA mobile terminal circuit part of the integrated terminal device performs normal operation in the voice call mode, and when receiving a voice call from the other party, conducts a voice call using the earphone / microphone jack of the integrated terminal device or executes an application program on the PC. You can make a voice call with the earphone / microphone jack using the sound card function of the notebook.

As such, the present invention integrates a CDMA mobile terminal mainly using voice and low-speed wireless data with a wireless LAN according to the IEEE802.11b standard to perform high-speed wireless Internet and voice calls.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. In other words, 5GHz band wireless LAN such as IEEE802.11a (54Mbps) in USA or HIPERLAN / 2 (54Mbps) in Europe, CDMA terminal and CDMA terminal are replaced with terminals such as synchronous / asynchronous IMT2000 terminal and GSM terminal. Can be combined into a device. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, an integrated terminal device of a mobile terminal and a wireless LAN according to the present invention integrates a CDMA mobile terminal and a wireless LAN according to the IEEE802.11b standard, which existed as independent areas, respectively, to provide high-speed wireless Internet and voice calls. There is an effect that can be performed.

In addition, the present invention can reduce the number of portable information devices by sharing the PCMCIA slot or USB terminal of the notebook. That is, by combining three devices such as a CDMA mobile terminal, a wireless LAN card, and a wireless modem card into one, it is possible to pursue simplicity.

In addition, the present invention has the advantage that the application field of the integrated terminal device is very extensive. This means that a wireless network can be easily constructed.

By operating the dual mode of CDMA data communication mode and wireless LAN mode, and the rest of the notebook or PC operating in wireless LAN mode using Ad-hoc mode, it is easy to build a wireless Internet network.

Furthermore, the present invention can solve the inconvenience caused by using the data connector of the CDMA mobile terminal for each model of each company by incorporating a USB terminal in the integrated terminal device, and convenience by using a universal USB cable.
