In addition, the TDS CDMA control module, group 110 is further controlled by the GSM control module 12 to control the GSM subscriber identity module 1 1376-931 group 140. It transmits a control command using the TDSCDMA Application Layer 111, and the control command is transmitted to the TDSCDMA Device Driver Layer 113 through the TDSCDMA Protocol Stack 112. The TDS CDMA device driver layer 113 further transmits a control command to the GSM device driver layer (GSM φ Device Driver Layer) 123 of the GSM control module 120 through the Universal Asynchronous Receiver/Transmitter (UART) specification, and finally passes through the GSM protocol stack ( The GSM Protocol Stack/SIM protocol 122 passes the control command to the GSM Application Layer of the GSM control module 120.

However, the prior art system has an inevitable deficiency, that is, such TDSCDMA • and GSM dual The model phone is not suitable for users with dual TDSCDMA subscriber identity modules, that is, users with dual USIM cards. Due to the dual-mode function of TDSCDMA and GSM dual-mode mobile phones, the user must have one USIM card and SIM card (including the chip or 1C built in the mobile phone) with φ individual TDSCDMA number and GSM number. If the user wants to use two USIM cards corresponding to the TDSCDMA number, they still need to purchase an additional mobile phone that can be inserted into the USIM card. Therefore, the user who has not applied for the GSM number and has the dual TDSCDMA number can not meet the demand, thereby reducing the practicability of the TDSCDMA and GSM dual-mode mobile phones. [Summary of the Invention]

The first TDSCDMA subscriber identity module or the second TDSCDMA subscriber identity module is stored by using a flash memory, an EEPR0M or an EPROM. However, the first TDSCDMA subscriber identity module is powered by the first USIM (User Service Identity Module) card for reading the data of the USIM+. The second TDSCDMA subscriber identity module is coupled to a second (10) card for reading data of the second USIM card. The invention has the effect that the prior art cannot achieve, that is, the TDSCDMA subscriber identity module of two different numbers can be configured on the TDSCDMA and the GSM dual-mode mobile phone, that is, the (10) (four) card that can electrically couple two corresponding TDSCDMA numbers. and

In addition, the 'GSM control module is only equivalent to the function of the transfer data, and does not need the agreement between the protocol machine and the SIM protocol, so it can reduce the complexity of the material and indirectly improve its performance. Not only reduce the development time of mobile phone manufacturers. And the cost also satisfies the needs of the psychological individualized enthusiasts who can also satisfy the business people and the new generation to the greatest extent. [Embodiment] Regarding the features and implementations of the present invention, the preferred embodiment is shown in conjunction with the drawings. The details are as follows. 1376931 Please refer to FIG. 2, which is a system architecture diagram of an embodiment of controlling the first and second TDSCDMA subscriber identity modules according to the present invention. The system includes a TDSCDMA (Time Division Synchronous Code Division Multiple Access) control module 210, a GSM (Global System for Mobile Communication) control module 220, and a first The TDSCDMA subscriber identity module 230 and a second TDSCDMA subscriber identity module 240. The TDSCDMA control module 210 includes a TDSCDMA Application Layer (211), a TDSCDMA Protocol Stack (212) and a TDSCDMA Device Driver Layer (213), and the GSM Control Module 220. A GSM application layer 221, a GSM protocol stack/SIM protocol 222 and a GSM device driver layer 223' are included, and a GSM is established in the GSM device driver layer 223. GSM Universal Asynchronous Receiver/Transmitter Driver > GSM UART Driver 2231 and a USIM (User Service Identity Module) and SIM (Subscriber Identification Module) driver module 2232.

The TDS CDMA device driver layer 213 is electrically coupled to the first TDSCDMA subscriber identity module 230; the GSM asynchronous transceiver driver module 2231 is interconnected with the USIM and SIM driver module 2232 and connected to the TDSCDMA 376931 device driver layer 213; The second TDSCDMA subscriber identity module 240 is electrically coupled to the USIM and the SIM driver module 2232. The system is based on the setting information of the first TDSCDMA subscriber identity module 230 or the second TDSCDMA subscriber identity module 240 stored in the dual mode handset, so that the TDSCDMA application layer 211 of the TDSCDMA control module 210 transmits correspondingly. The control command controls the actuation and data transfer of the first TDSCDMA subscriber identity module 230 via the TDS CDMA device driver layer 213. or

• The TDSCDMA control module 210 drives the layer 213 and the GSM asynchronous transceiver module 2231 via the TDS CDMA device to transmit control commands to the USIM and SIM driver module 2232' to control the operation and data of the second TDSCDMA subscriber identity module 240. transfer. When the TDSCDMA control module 210 controls the second TDSCDMA subscriber identity module 240, the GSM asynchronous transceiver driver module 2231 controls the USIM and the SIM driver module 2232 to perform a simplex serial port operation. Therefore, the GSM asynchronous transceiver driver module 2231 It can replace some functions of GSM application layer 221 ® and GSM protocol machine / SIM protocol 222, so it is not necessary to use gsm application layer 221, GSM protocol stack and its SIM protocol. In this example, the first TDSCDMA subscriber identity module 230 is electrically connected to a first USIM card (not shown). The second TDSCDMA subscriber identity module 240 is electrically coupled to a second USIM card (not shown). Next, the transmission information between the TDSCDMA device driver layer 213 and the GSM asynchronous transceiver driver module 2231 is controlled and transmitted by a Universal Asynchronous Receiver/Transmitter (UART) specification. Please refer to FIG. 3, which is a system flowchart of the present invention. Please refer to FIG. 2 for reference. The flow of the control method includes the following steps: · Performing system initialization (step S310), where TDSCDMA and GSM dual mode are performed. • When the mobile phone is powered on or reset, the initialization operation of the system is performed. It is determined whether a second TDSCDMA subscriber identity module 240 connected by a GSM control module 220 is on standby (step S320). The system retrieves the setting information for the machine to determine whether the second TDSCDMA subscriber identity module 240 is performing standby operation. The standby setting information is stored in the existing memory (not shown) of the TDSCDMA and GSM dual-mode mobile phones, and refers to the setting information of the memory storage by the TDSCDMA subscriber identity module. The memory itself can be a flash memory (F1 ash Memory) or an electronically erased read-only memory (Electrically Erasable Programmable).

Read-Only Memory ’ EEPR0M) or Erasable Programmable Read-Only Memory (EPROM)

If the result of the determination is no, then a first TDSCDMA subscriber identity module standby 230 is used to control the first TDSCDMA subscriber identity module 230 to which it is connected by using a TDSCDMA control module 210 (step S330). On the other hand, if the result of the determination in step S320 is YES, the second TDSCDMA subscriber identity module 240 is in standby of a GSM device driver layer 223 to establish a connection between one of the GSM asynchronous transceiver driver modules 2231 and a USIM. 13 1376931 SIM driver module 2232' and GSM asynchronous transceiver driver module 2231 communicates with TDSCDMA device driver layer 213 of one of TDSCDMA control modules 210 in an asynchronous transceiver (UART) specification to control connection with USIM and SIM driver module 2232 The second TDSCDMA subscriber identity module 240 (step S340). Please refer to FIG. 4, which is a detailed flowchart of the standby of the first TDSCDMA subscriber identity module in FIG. The system outputs a Φ-control command to the TDSCDMA device driver layer 213 via the TDSCDMA Application Layer 211 of the TDS CDMA Control Module 210 (step S331). When the TDS CDMA control module 210 transmits a control command via the TDS CDMA application layer 211, the TDS CDMA protocol stack 212 processes the control commands and outputs the processed control commands to the TDS CDMA device driver layer 213. According to the control command, the raw data (Raw Data) of the first TDSCDMA subscriber identity module 230 is obtained by the TDS CDMA device driver layer 213 (step S332). Thereafter, the TDS CDMA device driver layer 213 returns the original data to the TDSCDMA protocol stack 212 and processes the original data via the TDSCDMA protocol stack 212 (step S333). Finally, the processed raw data is returned to the TDSCDMA application layer 211 (step S334). Thereby, the control and data reading of the first TDSCDMA subscriber identity module 230 by the TDS CDMA control module 210 is completed, and the standby mode based on the first TDSCDMA subscriber identity module 230 is entered. Please refer to FIG. 5, which is a detailed flowchart of the standby of the second TDSCDMA subscriber identity module in FIG. The system outputs a control command to the GSM asynchronous transceiver driver module 2231 via the 14 1376931 TDSCDMA application layer 211 of the TDS CDMA control module 210 (step S341). When the system outputs a control command via the TDSCDMA application layer 211 of the TDS CDMA control module 210, the TDSCDMA protocol stack 212 of the TDS CDMA control module 210 processes the control commands and outputs them, and then uses the TDS CDMA device driver layer 213 to forward the control commands. To the GSM asynchronous transceiver driver module 2231. When this control command is output from the TDS CDMA device driver layer 213, the control command is transmitted via the asynchronous transceiver (UART) specification. Then, the GSM asynchronous transceiver driver module 2231 is used to analyze the control command and determine whether the control command is a valid command. If it is determined to be a valid command, the USIM and SIM driver module 2232 are used to control and obtain the second TDSCDMA subscriber identity module 240. The original data is transmitted back to the TDSCDMA protocol stack 212 of the TDS CDMA control module 210 through the GSM asynchronous transceiver driver module 2231 and the TDS CDMA device driver layer 213 (step S342). Prior to this, the GSM control module 220 configures its clock and operating voltage to conform to the electrical characteristics specification of the second TDSCDMA subscriber identity module 240 in accordance with the control command, and the second TDSCDMA subscriber identity module 24 〇 Initialization to facilitate control of the second TDSCDMA subscriber identity module 240 and the transmission of data. However, since the GSM protocol stack/SIM protocol 222 operates the second subscriber identity module 240 to be a simplex serial port operation, the GSM asynchronous transceiver driver module 2231 can partially replace the GSM protocol stack/SIM protocol 222 and the GSM application layer 221. The second user identification module 240 is controlled by the USIM and SIM driver module 2232. 15 1376931 In the process of returning the original data, the USIM and the SIM driver module 2232 first transmit the original data to the GSM asynchronous transceiver driver module 2231. The GSM heterogeneous transceiver driver module 2231 is via the asynchronous transceiver (UART) specification. The raw data is transmitted to the TDS CDMA device driver layer 213 through a predetermined baud rate, at which time the GSM control module 220 acts as a relay data. The TDS CDMA device driver layer 213 then transmits the raw data to the TDSCDMA protocol stack 212. Finally, the original data is processed through the TDSCDMA protocol stack 212 and the φ processed raw data is transmitted back to the TDSCDMA application layer 211 (step S343). The TDSCDMA application layer 211 processes the original data returned, thereby completing the TDSCDMA application layer 211. The initial control of the second TDSCDMA subscriber identity module 240 simultaneously enters a standby mode based on the second TDSCDMA subscriber identity module 240. The user can control the second TDSCDMA subscriber identity module 240 through the TDSCDMA application layer 211 and transmit the data. Please refer to FIG. 6 , which is a flowchart for selecting and recording the standby embodiment of the Φ 1st or 2nd TDSCDMA subscriber identity module according to an embodiment of the present invention, which includes the following processes: Acquiring and recording the first TDSCDMA subscriber identity The module 230 is in standby with the second TDSCDMA subscriber identity module 240 (step S410). This step has a number of different practices. The most common practice is to record flag data and store standby settings. When the user uses the TDSCDMA and GSM dual-mode mobile phone to perform handover or selects the control command of the first TDSCDMA subscriber identity module 230 or the second TDSCDMA subscriber identity 1769931 module 240, the system will retrieve the control command and control it according to the control. The command includes information to write a flag data or store the standby setting information of the first TDSCDMA subscriber identity module or the second TDSCDMA subscriber identity module that the user wants to use in the memory. The system is reset (step S420), and when the system is reset (or the TDSCDMA and the GSM dual-mode mobile phone are restarted), the flag data stored in the memory or the standby setting information is read to determine and drive the TDSCDMA control. The module 210 reads the original data of the first TDSCDMA subscriber identity module 230 or the second TDSCDMA subscriber identity module 240 to enter the standby mode of the first TDSCDMA subscriber identity module 230 or the second TDSCDMA subscriber identity module 240. In summary, the application of the present invention 11) 5(:1)]^(^)11 dual-mode mobile phone control system and method for dual TDSCDMA subscriber identity module can be provided without changing the hardware Through the cooperation between the control module, the GSM asynchronous transceiver driver module and the US IΜ and SIΜ driver modules, the second TDSCMA user identification loose group is controlled.
