Description

A mobile communication terminal and it's radio communication module

The present invention relates to a mobile communication terminal and a wireless communication module thereof.

The recent rapid development of mobile communication technology has provided huge development space for the mobile communication terminal market. There are currently two ways of realizing the mobile communication terminal.

The first method is to integrate a chip set of base band and radio frequency circuits. According to this method, a standard single or dual circuit board structure is used. Integrate with external circuitry. Mobile phones generally employ this method, which has the following problems. In other words, the design of radio frequency and baseband circuits is complicated, and full and meticulous mobile communication function testing is required, which greatly increased the R & D and production costs, the R & D cycle, and the rapid market entry of new products.

The second method is to design a wireless communication module by modularizing a wireless communication circuit, weld the module to a host, send and receive radio frequency by using a stable mature wireless communication module, baseband coding and decoding, and The protocol stack runs, and external circuits, including keyboards, LCDs, SIM cards, etc., realize control through the host. Currently, such a method is relatively rarely applied to a mobile phone, and generally, it is applied to a personal information product such as a PDA and a notebook computer to realize a wireless communication function. For example, a PDA has a wireless communication module typically connected to the host's main board. In addition, the wireless communication module and the host can be designed directly on a single printed board. In this case, the wireless communication module and the host are connected together through an interface circuit, and all of these wireless communication modules are installed inside the host. The plug-in does not support the way it works, and each manufacturer's interface is not standardized. The hardware structure is as shown in FIG. 1, and FIG. 1 is a view for explaining a hardware structure for realizing a wireless communication function of a PDA according to the prior art. In FIG. 1, the wireless communication module 100 includes a radio frequency antenna socket 102, a radio frequency processing unit 103, a baseband processing and power management unit 104, a storage device 105, and the like. The processing and power management unit 104 connects the radio frequency processing unit 103 and the storage device 105, transmits and receives radio frequencies, codes and decodes basebands, and operates a protocol stack. The frequency processing unit 103 and the baseband processing and power management unit 104 are connected to the interface circuit 111 of the host 110 through its interface circuit 101. The host 110 mainly controls the communication between the battery and the power management unit 112 and the interface for providing electricity to the wireless communication module 100 and the host 110 and other parts, thereby providing basic functions such as LCD display, keyboard control, and charge / discharge. A microcontroller (MCU) 113 for realization, a liquid crystal display (LCD) 114 for displaying man-machine interfaces and realizing information exchange and control activities between a user and a PDA, and a speaker and a microphone (SPK) for inputting and outputting voice signals. ≪ RTI ID = 0.0 > (115) < / RTI > 115, keyboard 116, SIM card 117, memory 118 for storing programs, ring tones, messages and phonebook of the host, radio frequency to connect radio frequency antenna 120 A portion such as an antenna plug 121. Among them, the signals transmitted between the interface circuits 101 and 111 include power signals, control signals, SIM card signals, data and command signals, and voice frequency signals, and the data and command signals are standard serial communication interfaces. This can be achieved through

Refer to FIG. 2 for the structure of the software for realizing the wireless communication function in the PDA. 2 is a diagram illustrating a software structure for realizing a wireless communication function with a PDA according to the prior art. The wireless communication module 200 includes an interface driving program 201, a CSD protocol 202, an AT command interpreter 203, a PPP protocol 204, an IP relay 205, a GPRS / GSM protocol stack 206, and a physical layer ( 207) and other software modules. Such software is stored in the storage device 105 of the wireless communication module 100 of FIG. 1 and is processed through the baseband processing and power management unit 104 of the wireless communication module 100.

The host 210 is an AT command / data processing program 211, an IP application program 212, a TCP / IP protocol 213, a PPP protocol 214, and an interface driving program to correspond to the wireless communication module 200. 215) and other software modules. Such software is stored in the storage device 118 of the host 110 of FIG. 1 and processed through the MCU 113 of the host 110.

Among them, the interface driving program 201 in the wireless communication module 200 and the interface driving program 215 in the host 210 correspond to each other in the same type of PDA. Since different types of PDAs may use different interfaces, the PDA interface drive programs may also be different, and generally use a serial communication interface.

The basic operating procedure under the software structure is as follows. In the case of sending a command, if an application program requires a mutual network on the host side, first, a corresponding message is wrapped in an AT command through an AT command processing program, and then sent through an interface driving program. On the wireless communication module side, the module receives the AT command through the interface driving and converts the actual protocol message to the protocol stack through the AT command interpretation layer.

When transmitting data, the data stream performs transparent transmission directly between the host side and the wireless communication module side through interface driving without passing through the processing of the AT analysis layer. The user selects CSD or GPRS to proceed with data transmission.

(1) If CSD is selected and data is transmitted to the outside, the AT command / data processing program on the host side sends an AT command requesting to connect a communication link through a serial port. AT command interpreter on the radio module side receives the AT command from the serial port and performs corresponding processing, and also controls the CSD protocol and the GPRS / GSM protocol to connect the data communication link. After the connection is established, the AT command interpreter on the radio module side returns the network information back to the AT command / data processing program on the host side, so that the AT command / data processing program can proceed with data transmission.

(2) If GPRS is selected and the data is transmitted to the outside, the AT command / data processing program on the host side, AT command interpreter on the radio module side, and GPRS / GSM protocol are in charge of the link. After the connection is successful, data transfer can proceed. The transmission of data can be completed through the IP application program of the host, the TCP / IP protocol, the PPP protocol of the radio module, and the IP relay.

The biggest advantage of this design method is that by simply changing the design of the host part, it avoids the redundant design of radio frequency (RF) and the main baseband circuit in the mobile communication terminal, which shortens the R & D cycle and enables the manufacturing company to produce new products more quickly. Can be marketed. However, the interface of wireless communication modules of other manufacturers is currently limited in various aspects when designing software and hardware.

Taking cell phones as an example, cell phone functions are becoming more and more powerful. Examples include vivid sound, color screens, sleek designs, and multimedia applications. These factors are the biggest cause of cell phone users changing their phones. However, the two types of mobile phones described above have one common problem.

Therefore, the wireless communication module that can be used repeatedly in the mobile phone has to be discarded. It wasted waste.
