1379575 IX. Description of the Invention: [Technical Field] The present invention relates to a method for controlling a dual GSM subscriber identity module, and more particularly to a method for controlling a dual GSM subscriber identity module for a GSM and TDSCDMA dual mode handset . [Prior Art]

At present, wireless communication technology has developed many normative standards. Common wireless communication systems include GSM (Global System for Mobi le Communication), CDMA (Code Division Multiple Access), PHS (Personal Handy). -phone System, personal hand-held telephone system), TDSCDMA (Time Division Synchronous Code Division Multiple Access), etc., in order to meet the needs of users of mobile phones that need to be able to switch between different standard systems, Mobile phone operators have developed mobile phones with a # dual-mode system, such as the presence of both GSM and TDSCDMA systems in a mobile phone. Please refer to Figure 1 for the prior art GSM and TDSCDMA dual mode system architecture. In the operation mode of the architecture, the GSM control module 11 can control the GSM subscriber identity module 130. The GSM subscriber identity module 130 can be electrically coupled to a SIM (Subscriber Identification Module) card. In addition, the GSM control module no can also control the TDSCDMA subscriber identity module 140 6 379 575 through the TDS CDMA control module 120. It transmits a control command using the GSM Application Layer 111, which is transmitted to the GSM Device Driver Layer 113 via the GSM Protocol Stack 112. The GSM device driver layer 113 further transmits a control command to the TDSCDMA device driver layer (TDSCDMA Device Driver Layer) 123 of the TDSCDMA control module 120 through a Universal Asynchronous Receiver/Transmitter (UART) specification, and finally • through the TDSCDMA protocol stack ( The TDSCDMA Protocol Stack) /USIM protocol 122 passes this control command to the TDSCDMA Application Layer 121 of the TDSCDMA Control Module 120. The TDSCDMA application layer 121 further analyzes whether the control command is valid. When determining that the control command is a valid command, the control command is transmitted to the TDSCDMA device driver layer 123 through the TDSCDMA protocol machine/USIM protocol 122 and the TDSCDMA user identification module is read. Group 14〇 raw data • (Raw Data), this TDSCDMA user identification module 14 is electrically connected - USIM (User Service Identity Module) card. The original data of the TDSCDMA subscriber identity module MO is then passed back to the TDSCDMA application layer 121 via the USIM protocol of the TDSCDMA control module 120, thereby acting as a response to this control command. Finally, the TDSCDMA application layer 121 calls the TDS CDMA device driver layer 123 to transmit the original data to the GSM device 7^1379575 driver layer 113 through the asynchronous multicast (UART) specification, and transmits the original data back to the GSM application layer 111 through the GSM protocol stack 112. The original data returned by the GSM application layer 111 is processed. However, the prior art system has an inevitable deficiency, that is, such a GSM and TDSCDMA dual-mode mobile phone cannot be applied to a user having a dual GSM subscriber identity module, that is, a user who has a dual SIM card. The prerequisite for the dual-mode function of the GSM and TDSCDMA dual-mode handsets is that the user must have a SIM card and a USIM card (including a chip or 1C built into the handset) with individual GSM numbers and TDSCDMA numbers. If the user wants to use two SIM cards corresponding to the GSM number, they still need to purchase an additional mobile phone with a SIM card. Therefore, the user who has not applied for the TDSCDMA number and has the dual GSM number can not meet the demand, thereby reducing the practicability of the GSM and TDSCDMA dual-mode mobile phones. SUMMARY OF THE INVENTION In view of the above, in order to solve the above problems, the present invention proposes a GSM (Global System for Mobile Communication) and TDSCDMA (Time Division Synchronous Code).

Division Multiple Access (Time Division Synchronous Code Division Multiple Access System) A dual-mode handset that controls the dual GSM subscriber identity module so that GSM and TDSCDMA dual-mode handsets can use two different numbers without changing the hardware. Dual GSM user identification module. The invention discloses a method for controlling a dual GSM user identification module by a GSM and TDSCDMA dual mode mobile phone. The GSM and TDSCDMA dual mode mobile phone has a gsm control module and a TDSCDMA control module. After the GSM and TDSCDMA dual-mode mobile phones are initialized by the system, it is judged whether one of the second GSM subscriber identity modules connected by the TDSCDMA control module stands by. If the judgment result is yes, the second GSM subscriber identity module stands by, and the dual mode handset establishes a TDSCDMA asynchronous transceiver driver module (TDSCDMA Universal) connected to a TDSCDMA Device Driver Layer (TDSCDMA Device Driver Layer).

Asynchronous Receiver/Transmitter Driver 'TDSCDMA UART Driver) and a SIM and USIM driver module, and the TDSCDMA asynchronous transceiver driver module communicates with the GSM device driver layer of one of the GSM control modules by the asynchronous transceiver (UART) specification to control and SIM A second GSM subscriber identity module coupled to the USIM driver module. If the result of the determination is no, the first (2) river user identification module stands by, and the dual mode mobile phone controls one of the first GSM subscriber identity modules by using the GSM control module. In addition, when the GSM and TDSCDMA dual-mode mobile phones are in the standby mode of the first GSM subscriber identity module or the second GSM subscriber identity module, the first GSM subscriber identity module or the second GSM subscriber identity can be acquired and recorded. Control commands or setting information for module standby. Then reset the system to perform the system initialization steps. The first GSM subscriber identity module or the second GSM subscriber identity module is stored by using a flash memory, an EEPR0M or an EPROM. However, the aforementioned first GSM subscriber identity module is powered. A first SIM (Subscriber Identification Module) card is coupled to read data of the first SIM card. The second GSM user 1379575 identifies the module to be electrically coupled to a second SIM card for reading data of the second SIM card. The invention has the efficiencies that can not be achieved by the prior art, and can configure two different numbers of GSM subscriber identity modules on the GSM and TDSCDMA dual-mode mobile phones, that is, the SIM cards corresponding to two GSM numbers can be electrically coupled. In addition to the control and data transmission of the first SIM card electrically coupled to the first GSM subscriber identity module, the GSM control module can be driven by the TDSCDMA asynchronous transceiver driver module _ and 511\1 and USIM drivers. The cooperation of the module is to control and transmit data to the second SIM card electrically coupled to the second GSM subscriber identity module. Therefore, for users with dual SIM cards, it is easy to control the dual GSM numbers and freely choose to use different GSM subscriber identity modules to stand by, without major hardware architecture changes. In addition, the TDSCDMA control module is only equivalent to the function of transiting data, and does not require the intervention of the TDSCDMA protocol stack and the USIM protocol, thereby reducing the complexity of the control program and indirectly improving its performance. Not only reduce the mobile phone # manufacturers' research and development time and cost also meet the modern people's desire for new changes, but also to meet the needs of business people and personalized enthusiasts. [Embodiment] The features and implementations of the present invention are described in detail with reference to the preferred embodiments. Please refer to FIG. 2, which is a system architecture diagram of the first and second GSft{user identification module embodiments of the present invention. This system contains _ (

Global System for Mobile Communication, Global Action Pass 1395575 system) control module 210, a TDSCDMA (Time Division Synchronous Code Division Multiple Access) control module 220, a first GSM user identification module Group 230 and a second GSM subscriber identity module 240. The GSM control module 210 includes a GSM Application Layer 211, a GSM Protocol Stack 212 and a GSM Device Driver Layer 213, and the TDSCDMA Control Mode Group 220 includes a TDSCDMA application layer (TDSCDMA Application)

Layer 221, a TDSCDMA Protocol Stack/USIM protocol 222 and a TDSCDMA Device Driver Layer 223' and a TDSCDMA asynchronous transceiver driver module (TDSCDMA Universal) in the TDSCDMA device driver layer 223 Asynchronous Receiver/Transmitter Driver, TDSCDMA UART Driver 2231 and a SIM (Subscriber • Identification Module 'User Identification Module) and uSIM (User

Service Identity Module (Driver Module) 2232. The GSM device driver layer 213 is electrically coupled to the first gsm subscriber identity module 230; the TDSCDMA asynchronous transceiver driver module 2231 is interconnected with the SIM and USIM driver module 2232 and connected to the gsm device driver layer 213, and the second The GSM subscriber identity module, group 240 is electrically coupled to the sim and USIM driver module 2232. 1379575

The system is based on the setting information of the GSM subscriber identity module 230 stored in the dual mode mobile phone or the second GSM subscriber identity module 240, so that the GSM application layer 211 of the GSM control module 210 sends the corresponding information. The control command 'controls the actuation and data transfer of the first GSM subscriber identity module 230 via the GSM device driver layer 213. Or the 'gsm control module 210 transmits the control command to the SIM and USIM driver module 2232 via the GSM device driver layer 213 and the TDSCDMA asynchronous transceiver module 2231 to control the operation of the second GSM user identification module 240. Data transfer. When the GSM control module 21 controls the second GSM subscriber identity module 240, the TDSCDMA asynchronous transceiver driver module 2231 controls the SIM and the USIM driver module 2232 to perform a simple serial port operation. Therefore, the TDSCDMA asynchronous transceiver driver module 2231 can replace some functions of TDSCDMA application layer 221 and TDSCDMA protocol stack/USIM protocol 222, so there is no need to utilize TDSCDMA application layer 221 and TDSCDMA protocol stack/USIM protocol 222. • In this example, the first GSM subscriber identity module 230 is electrically coupled to a first SIM card (not shown). The second GSM subscriber identity module 240 is electrically connected to a second SIM card (not shown). Next, the communication message between the GSM device driver layer 213 and the TDSCDMA asynchronous transceiver driver module 2231 is used to perform control commands and data aggregation and transmission through a Universal Asynchronous Receiver/Transmitter (UART) specification. Please refer to FIG. 3, which is a flowchart of the system of the present invention. Please refer to FIG. 2 1379575 for the second diagram. The flow of the control method includes the following steps: Perform system initialization (step S310), and perform initialization of the system when the GSM and TDSCDMA dual-mode mobile phones are powered on or reset. It is determined whether a second GSM subscriber identity module 240 connected by a TDS CDMA control module 220 is in standby (step S320). The system retrieves the setting information for standby to determine whether the second GSM subscriber identity module 240 is performing standby operation. The standby setting information is stored in the existing memory (not shown) of the GSM and TDSCDMA dual-mode mobile phones, which means that the memory stores the setting information of the standby operation of the G S Μ user identification module. The memory itself can be a Flash Memory, an Electrically Erasable Programmable Read-Only Memory (EEPROM) or an Erasable Programmable Read-Only Memory (Erasable Programmable Read- Only Memory). EPROM) If the result of the determination is no, a first GSM subscriber identity module standby unit 230 controls the first GSM subscriber identity module 230 to which it is connected by using a GSM control module 210 (step S330). On the other hand, if the result of the determination in step S320 is YES, the second GSM subscriber identity module 240 is in standby of a TDSCDMA device driver layer 223 to establish a mutually connected TDSCDMA asynchronous transceiver driver module 2231 and a SIM. The USIM driver module 2232' and the TDSCDMA asynchronous transceiver driver module 2231 communicate with the GSM device driver layer 213 of one of the GSM control modules 210 in an asynchronous transceiver (UART) specification to control connection with the SIM and USIM driver module 2232 13 1379575. The second GSM subscriber identity module 240 (step S340). Please refer to FIG. 4, which is a detailed flowchart of the standby of the first GSM subscriber identity module in FIG. The system is via the GSM application of the GSM control module 210

The GSM Application Layer 211 outputs a control command to the GSM device driver layer 213 (step S331). When the GSM control module 210 transmits a control command via the GSM application layer 211, the GSM protocol stack 212 is used to process the control commands and output the processed control commands to the GSM device driver layer 213. Based on the control command, the raw data (RawData) of the first GSM subscriber identity module 230 is obtained by the GSM device driver layer 213 (step S332). The GSM device driver layer 213 then transmits the original data back to the GSM protocol stack 212 and processes the original data via the GSM protocol stack 212 (step S333). Finally, the processed raw data is returned to the GSM application layer 211 (step S334). Thereby, the control and data reading of the first GSM subscriber identity module 230 by the GSM control module 210 is completed, and at the same time, the standby mode in which the first GSM subscriber identity module 230 is dominant is entered. Please refer to FIG. 5, which is a detailed flowchart of the second GSM subscriber identity module standby in FIG. The system outputs a control command to the TDSCDMA asynchronous transceiver driver module 2231 via the GSM application layer 211 of the GSM control module 210 (step S341). When the system outputs a control command via the GSM application layer 211 of the GSM control module 210, the GSM protocol machine 212 of the GSM control module 210 processes the control command and outputs 'reuse the gsm device driver layer 213 to forward the control command to the TDSCDMA asynchronous. Transceiver drive module 2231. This control 14 1379575

When the command is output from the GSM split driver layer 213, the control command is transmitted via the asynchronous transceiver (UART) gauge fc. Then, the TDSCDMA asynchronous transceiver driver module 2231 is used to analyze the control command and determine whether the control command is a valid command. If the command is valid, the SIM and USIM driver module 2232 are used to control and obtain the second GSM subscriber identity module. The original data is transmitted back to the GSM protocol stack 212 of the GSM control module 210 through the TDSCDMA asynchronous transceiver driver module 2231 and the GSM device driver layer 213 (step S342). Prior to this, the TDSCDMA control module 220 is based on the original data. The control command configures its operating clock and operating voltage to conform to the electrical characteristics specification of the second GSM subscriber identity module 240, and initializes the second GSM subscriber identity module 24 to facilitate control of the second GSM subscriber identity module. 240 and the transmission of data. However, since the TDSCDMA protocol stack/USIM protocol 222 operates the second subscriber identity module 240 to be a simplex serial port operation, the TDSCDMA asynchronous transceiver driver module 2231 can partially replace the TDSCDMA protocol stack/USIM protocol 222 and the TDSCDMA application layer. The second user identification module 240 is controlled by the SIM and USIM driver module 2232. In the process of returning the original data, the SIM and USIM driver module 2232 first transmits the original data to the TDSCDMA asynchronous transceiver driver module 2231. The TDSCDMA asynchronous transceiver driver module 2231 passes the asynchronous transceiver (UART) specification to pass certain The baud rate transfers the raw data to the GSM device driver layer 213, at which point the TDS CDMA control module 220 acts as a relay data 15 1379575. The GSM device driver layer 213 then transmits the raw data to the GSM protocol stack 212. Finally, the original data is processed through the GSM protocol stack 212 and the processed original data is transmitted back to the GSM application layer 211 (step S343), and the GSM application layer 211 processes the original data returned, thereby completing the GSM application layer 211. The initial control of the GSM subscriber identity module 240 simultaneously enters a standby mode based on the second GSM subscriber identity module 240. The user can control the second GSM subscriber identity module 240 and transmit data through the GSM application layer 211. Please refer to FIG. 6, which is a flowchart of selecting and recording a standby embodiment of the first or second GSM subscriber identity module according to an embodiment of the present invention, which includes the following processes:

The acquisition and recording are performed by the first GSM subscriber identity module 230 or by the second GSM subscriber identity module 240 (step S410). This step has a number of different approaches. The most common practice is to record flag data and store standby information. When the user uses the GSM and TDSCDMA dual-mode mobile phone to make a handover or select a control command with the first GSM subscriber identity module 230 or the second GSM subscriber identity module 24, 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 GSM subscriber identity module or the second GSM subscriber identity module that the user wants to use in the memory. Reset the system (step S420), when the system is reset (or GSM and 16 1379575 TDSCDMA dual-mode hands are restarted), the flag data stored in the memory or the standby setting information will be read to determine and drive The GSM control module 21 reads the original data of the first GSM subscriber identity module 230 or the second GSM subscriber identity module 240 to enter the standby of the first GSM subscriber identity module 230 or the second GSM subscriber identity module 240. mode. In summary, the system and method for controlling dual GSM subscriber identity modules using the GSM and TDSCDMA dual-mode mobile phones provided by the present invention can be carried out through the GSM control module and the TDSCDMA asynchronous transceiver driver without changing the hardware. The cooperation between the module and the SIM and the USIM driver module controls the second GSM subscriber identity module. Therefore, the user can control and switch the standby mode of the SIM cards of two different GSM numbers to provide the GSM and TDSCDMA. The practicality of the dual-mode phone.
