Description

200901739 IX. Description of the Invention: [Technical Field] The present invention relates to a method for controlling a dual TDSCDMA subscriber identity module, and more particularly to a method for controlling a dual TDSCDMA subscriber identity module for a TDSCDMA and GSM dual mode handset . [Prior Art] At present, wireless communication technology has developed many normative standards. Common wireless communication systems include GSM (Global System for Mobile 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 to switch to different standard systems, Mobile phone operators have developed mobile phones with dual-mode systems, such as TDSCDMA and GSM systems in one mobile phone. Please refer to Figure 1 for the prior art TDSCDMA and GSM dual mode system architecture. In the operation mode of the architecture, the TDSCDMA control module 110 can control the TDSCDMA subscriber identity module 130. The TDSCDMA subscriber identity module 130 can be electrically connected to a USIM (User Service Identity Module) card. . In addition, the TDSCDMA control module 110 can also control the GSM subscriber identity module 6 200901739 via the GSM control module 120. It transmits a control command using the TDSCDMA Application Layer (TDSCDMA Protocol Layer) 111, and the control command is transmitted to the TDSCDMA Device Driver Layer 113 through the TDSCDMA Protocol Stack 112. The TDSCDMA device driver layer 113 further transmits a control command to the GSM device driver layer (GSM " Device Driver Layer) 123 of the GSM control module 120 through the Universal Asynchronous Receiver/Transmitter (UART) specification, and finally passes the GSM protocol stack. (GSM Protocol Stack) /SIM protocol 122 delivers this control command to the GSM Application Layer 121 of the GSM Control Module 120.

The GSM 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 GSM device driver layer 123 and read by the GSM protocol stack/SIM protocol 122. Raw data of the module 140, the GSM user identification module 140 is electrically coupled to a siM (Subscriber)

Identification Module, User Identification Module) card. The original data of the GSM subscriber identity module 140 is then passed back to the GSM application layer 121 via the SIM protocol of the GSM control module 120, thereby acting as a response to this control command. Finally, the GSM application layer 121 calls the GSM device driver layer 123 to transmit the original data to the penalty 3 (;: 1) device-driven layer 7 through the asynchronous transceiver (UART) specification.

113, and the original data is transmitted back to the TDSCDMA application layer 111 through the TDSCDMA protocol stack 112. The original data returned by the TDSCDMA application layer 111 is processed, but the prior art system has an inevitable deficiency, that is, the TDSCDMA and GSM dual mode. A mobile phone cannot be applied to a user with a dual TDSCDMA subscriber identity module', that is, a subscriber who has dual USIM cards. The prerequisite for using the dual-mode function with the GSM dual-mode mobile phone is that the user must have one USIM card and SIM card (including the chip or 1C built into the mobile phone) with the corresponding TDSCDMA number and GSM number. If the user wants to use two USIM cards corresponding to the TDSCDMA number, they still need to buy an additional mobile phone with a usiM card. Therefore, the user's demand for a dual TDSCDMA number that does not apply for a GSM number cannot be met, thereby reducing the utility of the TDSCDMA and GSM dual-mode handset. SUMMARY OF THE INVENTION In view of the above, in order to solve the above problems, the present invention proposes a Despite (3)! (Time Division Synchronous Code Division Multiple Access) and GSM (Global System for Mobile Communication, Global Mobile Telecommunications System) A dual-mode handset that controls the dual TDSCDMA subscriber identity module so that TDSCDMA and GSM dual-mode handsets can use two different TDSCDMA subscriber identity modules without changing the hardware. The invention discloses a TDSCDMA and GSM dual-mode mobile phone control double 8 200901739 TDSCDMA subscriber identity module. The TDSCDMA and GSM dual-mode mobile phone has a TDSCDMA control module and a GSM control module. After the TDSCDMA and GSM dual-mode mobile phones are initialized, it is determined whether one of the second TDSCDMA subscriber identity modules connected by the GSM control module is on standby. If the judgment result is YES, the second TDSCDMA subscriber identity module is standby, and the dual-mode handset establishes a GSM asynchronous Asynchronous Receiver/Driver module in a GSM Device Driver Layer. Transmitter Driver, GSM UART Driver) and a USIM and SIM driver module, and the GSM asynchronous transceiver driver module communicates with the TDSCDMA device driver layer of the TDSCDMA control module by the asynchronous transceiver (UART) specification to control the USIM and SIM drivers. The second TDSCDMA subscriber identity module connected by the module. If the result of the determination is no, the first TDSCDMA subscriber identity module is in standby. The dual mode handset controls the first TDSCDMA subscriber identity module by using the TDS CDMA control module. In addition, when the TDSCDMA and GSM dual-mode mobile phones are in the standby mode of the first TDSCDMA subscriber identity module or the second TDSCDMA subscriber identity module, the first TDSCDMA subscriber identity module or the second TDSCDMA 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 TDSCMA user identification module or the second TDSCDMA user identification module is stored by using a flash memory, an EEPR0M or an EPROM. However, the first TDSCDMA subscriber identity module power supply 200901739 is coupled to a first USIM (User Service Identity Module) card for reading the data of the first 114 card. 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 two different numbers iTDSCDM user identification module can be configured on the kTDSCDMA and the GSM dual-mode mobile phone, that is, the USIM+ can electrically couple two corresponding TDSCDMA numbers. The TDSCDMA control module can control the transmission and data transmission of the first USIM card electrically coupled to the first TDSCMA subscriber identity module, and can also pass the GSM asynchronous transceiver driver module and the USIM and SIM driver module. In cooperation, the second USIM card that is electrically connected to the second TDSCDMA subscriber identity module is controlled and transmitted. Therefore, for users with dual USIM cards, it is easy to control the dual TDSCDMA number and freely choose to use different TDSCDMA subscriber identity modules to stand by, without major hardware architecture changes. In addition, the GSM control module is only equivalent to the function of transiting data, without the intervention of the GSM protocol stack and the SIM protocol, thus reducing the complexity of the control program and indirectly improving its performance. Not only does it reduce the development time and cost of mobile phone manufacturers, but it also meets the needs of modern people seeking new changes. It can also meet the needs of business people and personalized enthusiasts. [Embodiment] The features and implementations of the present invention will be described in conjunction with the preferred embodiments. 200901739 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 (TDSCDMA Application Layer) 21, a TDSCDMA Protocol Stack 212 and a TDSCDMA Device Driver Layer 213, and GSM. The control module 220 includes a GSM application layer ( GSM Application Layer) 221, a GSM protocol stack (SIM Protocol Stack) / SIM protocol 222 and a GSM device driver layer 223, and is used in the GSM device. A GSM Universal Asynchronous Receiver/Transmitter Driver (GSM UART Driver) 2231 and a USIM (User Service Identity Module) and SIM (Subscriber Identification Module) are established in the driver layer 223. Module) drive module 2232.

The TDSCDMA 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 TDSCDMA 200901739 « « 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 sends the phase to the TDSCDMA application layer 211 of the TDSCDMA control module 210 based on the first TDSCD|IA subscriber identity module 230 stored in the dual mode handset or the standby information of the second TDSCDMA subscriber identity module 240. The corresponding 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 " 'Draw' (3) control module 210 via TDS CDMA device driver layer 213 and GSM asynchronous transceiver driver module 2231 'to transfer control commands to USIM and SIM driver module 2232 ' to control the second TDSCDMA subscriber identity module 240 action and data transmission. When the TDS CDMA control module 210 controls the second TDSCDMA subscriber identity module 240, the GSM asynchronous transceiver driver module 2231 controls the USI Μ and the SI Μ driver module 2232 to perform a simple serial port operation. 2231 can replace GSM application layer 221 /

With some functions of the GSM protocol stack/SIM protocol 222, it is not necessary to utilize the GSM application layer 221, the GSM protocol stack and its SIM protocol. In this example, the first TDSCDMA subscriber identity module 230 is electrically coupled 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 flowchart of the system of the present invention. Please refer to Fig. 2 for understanding. The flow of the control method includes the following steps: Performing system initialization (step S310), where the initialization operation of the system is performed when the TDSCDMA and the GSM dual-mode mobile phone are powered on or the system is reset. It is determined whether a second TDSCDMA subscriber identity module 240 connected by a GSM control module 220 is in standby (step S320). The system retrieves the setting information for the standby 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) o If the result of the judgment is no, the first TDSCDMA user identification module is in standby 230'. The TDS CDMA control module 210 controls the first TDSCDMA subscriber identity module 230 to which it is connected (step S330). On the other hand, if the result of the determination in step S320 is YES, the second TDSCDMA subscriber identity module 240 stands by, and a GSM device driver layer 223 establishes a connection between the GSM asynchronous transceiver driver module 2231 and a USIM. 13 200901739 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 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 is used to process the control commands and output the processed control commands to the TDS CDMA device driver layer 213. According to the control command, the original data of the first TDSCDMA subscriber identity module 230 is obtained by using the TDS CDMA device driver layer 213 (Raw

Data) (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 transceiving driving module 2231 via the TDSCDMA control module 210 of the 2009/2009 TDSCDMA application layer 211 (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 drive module 2231. When the 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 the clock and operating voltage according to the control command to conform to the electrical characteristic specification of the second TDSCDMA subscriber identity module 240, and the second TDSCDMA subscriber identity module 240. Initialization, in order to control the second TDSCDMA subscriber identity module 240 and perform data transmission. 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 200901739 In the process of returning the original data, the USIM and SIM driver module 2232 first transmits the original data to the GSM asynchronous transceiver driver module 2231. The GSM asynchronous transceiver driver module 2231 passes the asynchronous transceiver (UART) specification to pass certain The baud rate transmits the original data to the TDS CDMA device driver layer 213, 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 processed original data is transmitted back to the TDSCDMA application layer 211 (step S343). The TDSCDMA application layer 211 processes the backhaul original data, thereby completing the TDSCDMA application layer 211 to the second. The initial control of the TDSCDMA subscriber identity module 240 simultaneously enters a standby mode in which the second TDSCDMA subscriber identity module 240 is dominant. 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 of selecting and recording a standby embodiment of a first or second TDSCDMA subscriber identity module according to an embodiment of the present invention, which includes the following processes: Acquiring and recording a first TDSCDMA subscriber identity module The group 230 or the second TDSCDMA subscriber identity module 240 is on standby (step S410). This step has a number of different practices. The most common practice is to record the flag data and store the 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 16 200901739 module 240, the system will retrieve the control command and The control 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.

Reset the system (step S420), when the system is reset (or restart the TDSCDMA and GSM dual-mode mobile phone), it will read the flag data stored in the memory or the standby setting information 'to judge and drive ^^ (3) The dragon control module 21 takes the original data of the first TDSCDMA subscriber identity module 23 or the second TDSCDMA subscriber identity module 240 to enter the first TDSCMA subscriber identity module 230 or the second TDSCDMA subscriber identity module 24 The standby mode. In summary, the system and method for controlling the dual TDSCDMA subscriber identity module using the 1^(:1)]^ and GSM dual-mode mobile phone provided by the present invention can be carried out through TDSCDMA without changing the hardware. The control module, the GSM asynchronous transceiver driver pull group and the US IΜ and the SIΜ drive module cooperate to control the second TDSCDMA subscriber identity module, so the user can control the one of the two different TDSCMA numbers.
