The conventional dual-mode mobile phones are equipped with two processors corresponding to different communication network systems, and each of the two processors provides a corresponding clock, data, power supply voltage, and reset signal to the connected chip deck. To access the data of the wafer card on which it is configured. However, the structure and working principle of the GSM chip card, the PHS chip card or the CDMA chip card card are the same, that is, the pins for transmitting the clock, data, power voltage, and reset signal are configured for the processor. Access the data of the wafer card. Therefore, by separately adding a switching unit between the two sets of processors and the card holder, and selecting the source of the data transmission for the different needs of the user, the data of the wafer card is transmitted to the processor, thereby achieving Dual mode single standby function. The invention is a dual-mode single standby handheld communication device developed according to the above concept. In order to clarify the content of the present invention, the following specific examples are given as examples in which the present invention can be implemented.

Those skilled in the art are able to hold the hand when visually needed. Any two communication network systems of GSM, PHS and CDMA are arranged in the communication device.

As shown in FIG. 2, the handheld communication device 200 of the present embodiment includes a CDMA communication processing unit 210, a GSM communication processing unit 220, a CDMA chip card holder 230, and a GSM chip card holder 240. The switching unit 250 is further disposed between the CDMA communication processing unit 210 and the CDMA chip card holder 230; and the switching unit 260 is disposed between the GSM communication processing unit 220 and the GSM chip card holder 240. It should be noted that an embodiment of the present invention is applicable to the handheld communication device 200 including the CDMA communication processing unit 210 and the GSM communication processing unit 220. The user can select the CDMA communication processing unit 210 and the GSM communication processing unit 220 according to the needs thereof. First, as a system processing unit in the handheld communication device 200 that mainly controls its functional operation. The following is a detailed description of the functions of the various components in the handheld communication device 200: the CDMA chip cartridge 230, hence the name, is used to configure the CDMA chip. Similarly, the GSM chip cartridge 240 is used to configure the GSM chip. However, as described above, since the structure and working principle of the CDMA chip card holder 230 and the GSM chip card holder 240 are the same, in the embodiment, the type of the wafer card disposed thereon is not limited, and the user can select the same configuration as needed. Or a wafer card of a different type (including GSM, PHS, and CDMA). Hereinafter, the chip card disposed in the CDMA chip card holder 230 is referred to as a first chip card, and the wafer card disposed in the GSM chip card holder 240 is referred to as a second chip. The chip card is used to show the difference.

The CDMA communication processing unit 210 is connected to the CDMA chip card holder 230 through the switching unit 250 to access the data of the first chip card. Alternatively, the CDMA chip processing unit 260 can be connected to the GSM chip card holder 240 to access the second wafer card. data of. After receiving the data of the wafer card, the data obtained by the access can be dialed to the CDMA communication network to implement the call.

The GSM communication processing unit 220 includes, for example, a clock, a data, a power supply voltage, and a reset signal to the wafer deck for the wafer card holder to access the data of the wafer card.

Under normal circumstances, the CDMA chip card 230 should be equipped with a CDMA chip card, and the GSM chip card 240 should be configured with a GSM chip card, so when the CDMA communication processing unit 210 sends the clock, data, and power corresponding to the CDMA system. When the voltage and reset signal are sent to the CDMA chip deck 230, the data of the CDMA chip card can be correctly read. Similarly, the GSM communication processing unit 220 can also correctly read the data of the GSM chip card through the GSM chip card holder 240, which is a so-called CDMA/GSM dual mode dual standby function.

However, in addition to the above-mentioned original dual-mode dual standby function, when the user has two CDMA chip cards or two GSM chip cards at the same time, and wants to be able to use the same handheld communication device, the wafer card is placed. After that, it will cause problems such as the clock, data, power supply voltage and reset signal sent by one of the communication processing units and the chip deck. Therefore, in this embodiment, the switching unit 250 is disposed between the CDMA communication processing unit 210 and the CDMA chip card holder 230, and the switching unit 260 is disposed between the GSM communication processing unit 220 and the GSM chip card holder 240, and can be configured according to The user's selection, by switching of the switching units 250, 260, transfers the required wafer card data to the correct communication processing unit.

When the user wants to use the dual-mode single standby function, it is necessary to prepare two wafer cards of the same communication network system and pre-position them into the CDMA chip holder 230 and the GSM chip holder 240 of the handheld communication device 200. After the power of the handheld communication device 200 is activated, the system processing unit (the CDMA communication processing unit 210 or the GSM communication processing unit 220) of the handheld communication device 200 controls the switching unit 250 to switch to the CDMA through the control terminal K1 of the switching unit 250. The communication processing unit 210 controls the switching unit 260 to switch to the GSM communication processing unit 220 through the control terminal K2 of the switching unit 260. It should be noted that the present invention is applicable to a dual-mode dual-processor handheld communication device, and in order to save cost, such a handheld communication device usually selects one of the two processing units as a system processing unit to execute the handheld communication device. The main operational features.

In the above, the CDMA communication processing unit 210 and the GSM communication processing unit 220 respectively send corresponding clocks, data, power supply voltages, and reset signals to the CDMA chip card holder 230 and the GSM chip card holder 240, and the handheld communication device 200 can Access the data of the wafer card on which it is configured. At this time, since the types of the inserted wafer cards are the same, the signals sent by the communication processing unit and the wafer cassette are inconsistent with the wafer card, and the handheld communication device 200 immediately displays the status on the built-in screen. To prompt the user to replace the wafer card or select the dual mode single standby function. The above-mentioned replacement of the correct wafer card (ie, placing the CDMA chip card in the CDMA wafer deck 230 and placing the GSM chip card in the GSM wafer card holder 240) and performing the dual mode dual standby mode is the original function of the dual mode mobile phone.
