Description

200901733 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 PHS 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), and PHS (Personal Handy-phone System, personal hand-held telephone system, etc., in order to meet the needs of users' mobile phones to switch to different standard systems, mobile phone carriers have developed mobile phones with dual-mode systems, such as in a mobile phone. The existence of GSM and PHS systems is one of the representatives. Please refer to Figure 1 for the prior art GSM and PHS dual-mode system architecture. In the operation mode of the architecture, the GSM control module 110 can control the GSM subscriber identity module 130. The GSM subscriber identity module 130 can electrically transfer a SIM (Subscriber Identification Module) card. In addition, the GSM control module 110 can also control the PHS subscriber identity module 140 through the PHS control module 120. It transmits a control command using the GSM Application Layer 111, and the control command is transmitted to the GSM Device Driver Layer 113 through the GSM Protocol Stack 112 6 200901733. The GSM device driver layer 113 further transmits a control command to the PHS Device Driver Layer 123 of the PHS control module 120 through a Universal Asynchronous Receiver/Transmitter (UART) specification, and finally passes the PHS protocol stack (PHS). The Protocol Stack) /PIM protocol 122 passes this control command to the PHS Application Layer 121 of the PHS control module 120.

The PHS application layer 121 further analyzes whether the control command is valid. When determining that the control command is a valid command, the PHS protocol stack/PIM protocol 122 is used as an intermediary to transmit the control command to the Phs device driver layer 123 and read the PHS user identification mode. The Raw Data of the group 140 is electrically coupled to a piM (Pers〇nal Identky Module) card. The raw data of the pHS subscriber identity module 14A is then transmitted through the piM protocol of the PHS control module 12 (piM).

Protocol) is passed back to the PHS application layer 121 as a response to this control command. Finally, the PHS application layer 121 calls the pHS device driver layer 123 to transmit the original data to the (3) device driver layer 113 through the asynchronous transceiver (UART) specification, and transmits the original data back to the gsm application layer through the GSM protocol stack 112. Off 1U processes the raw data returned. However, the prior art system has an inevitable deficiency, that is, such gsm and PHS dual-mode mobile phones cannot be as good as money (2), and the households use the group. 7 200901733 Users refer to users who have dual SIM cards. For GSM and PHS dual-mode phones, the prerequisite for using the dual-mode function is that the user must have a SIM card and a PIM card (including the chip or 1C built into the phone) with individual GSM numbers and PHS numbers. If the user wants to use two SIM cards corresponding to the GSM number, they still need to buy an additional mobile phone with a SIM card. Similarly, the PHS control module and the connected PHS user identification module of the GSM and PHS dual-mode mobile phones are completely useless, and thus cannot meet the needs of users who have dual GSM numbers without applying for a PHS number. In turn, the utility of this GSM and PHS dual-mode mobile phone is reduced. [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) system and a PHS (Personal Handy-phone System) dual-mode mobile phone to control dual GSM users.

Module and a PHS control module. After the GSM and PHS dual-mode mobile phones are initialized, it is determined whether one of the second GSM subscriber identity modules connected by the PHS control module is on standby. If the judgment result is yes, the second GSM user identification module stands by, and the dual-mode mobile phone is on the PHS 8 (2009) layer.

Device Driver Layer) establishes a PHS Universal Asynchronous Receiver/Transmitter Driver (PHS UART Driver) and a SIM and PIM driver module, and the PHS asynchronous transceiver driver module asynchronously transmits and receives (UART). The specification communicates with the GSM device driver layer of one of the GSM control modules to control the second GSM user identification module connected to the sim and PIM driver modules. If the judgment result is no, the first GSM subscriber identity module is standby, and the dual mode handset controls one of the first GSM subscriber identity modules connected by the gsm control module. In addition, when the GSM and PHS 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 can be obtained and recorded. Identify control commands or setting information for module standby. Then reset the system to perform the system initialization steps. The first GSM user identification module or the second (38) user identification module is stored by using a flash memory, an EEPROM or an EPROM. d, as described in the first GSM user. The identification module is electrically coupled to the first SIM (Subscriber Identification Module) card for reading data of the first SIM card, and the second GSM user identifies the replacement system for the power supply secret - the second SIM The card 'is for reading the data of the second SIM card. The invention has the effect that the prior art cannot achieve, that is, the gs family identification module of two different numbers can be configured on the GSM and PHS dual-mode mobile phones, that is, 9 200901733 is available Two SIM cards corresponding to the GSM number are electrically coupled, and the GSM control module can pass the PHS in addition to the control and data transmission of the first SIM card electrically coupled to the first GSM subscriber identity module. The asynchronous transceiver driver module cooperates with the SIM and the ΠΜ drive module to control and transmit data to the second SIM card electrically connected to the second gsm subscriber identity module. Therefore, for a user with dual SIM cards Can also easily implement double gsm numbers The system is free to choose different GSM user identification modules to stand by, and does not need to make major changes to the hardware architecture. In addition, the PHS control module is only equivalent to the function of transferring data, without the intervention of PHS protocol stack and PIM protocol. Therefore, it can reduce the complexity of the control program and indirectly improve its performance. Not only reduce the development time and cost of mobile phone manufacturers, but 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 below with reference to the preferred embodiments. Referring to Figure 2, it is an embodiment of controlling the first and second GSM subscriber identity modules of the present invention. System architecture diagram. The system includes a GSM (Global System for Mobile Communication) control module 210, a PHS (Personal Handy-phone System) control module 220, and a first The GSM subscriber identity module 230 and a second GSM subscriber identity module 240. The GSM control module 210 includes a GSM application layer (GSM Applica) Tion 10 200901733

Layer 2) GSM Protocol Stack 212 and a GSM Device Driver Layer 213, and the PHS Control Module 220 includes a PHS Application Layer 221 and a PHS protocol. PHS Protocol Stack / PIM Protocol 222 and a PHS Device Driver Layer 223, and a PHS Universal Asynchronous Receiver/Transmitter Driver (PHS) is built in the PHS device driver layer 223. PHS UART Driver 2231 and a SIM (Subscriber Identification Module) and piM (Personal Identity Module) driver module 2232. The GSM device driver layer 213 is electrically connected to the first GSM subscriber identity module 230; the PHS asynchronous transceiver driver module 2231 is interconnected with the SIM and PIM driver module 2232 and connected to the GSM device driver layer 213, and the second The GSM subscriber identity module 240 is electrically connected to the sim and PIM driver module 2232. The system is based on the setting information of the first Gsm user identification module 230 or the second GSM user identification module 240 stored in the dual-mode mobile phone, 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. Alternatively, the GSM control module 21 transmits the control command to the SIM and PIM driver module 2232 via the GSM device driver layer 213 and the PHS asynchronous transceiver driver module 2231 to control the 11th 200901733 second GSM subscriber identity module 240. Actuation and data transfer. When the GSM control module 210 controls the second GSM subscriber identity module 240, the PHS asynchronous transceiver driver module 2231 controls the SIM and PIM driver module 2232 to perform a simple serial port operation. Therefore, the PHS asynchronous transceiver driver module 2231 It can replace some functions of the PHS application layer 221 and the PHS protocol stack/PIM protocol 222, so it is not necessary to utilize the PHS application layer 221, the PHS protocol stack/PIM protocol 222. In this example, the first GSM subscriber identity module 230 is electrically connected to a first SIM card (not shown). The second GSM subscriber identity module 240 is electrically coupled to a second SIM card (not shown). Next, the communication message between the GSM device driver layer 213 and the PHS asynchronous transceiver driver module 2231 is used to perform control commands and data aggregation and transmission through a Universal Asynchronous Receiver/Transmitter (UART) specification. Refer to Figure 3 in May for the flow chart of the invention. Please refer to Figure 2 for understanding. 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 PHS dual-mode phones are powered on or reset. It is determined whether one of the second GSM subscriber identity modules 240 connected by a PHS control module 220 is on standby (step S320). The system retrieves the setting information for standby to determine whether the second GSM subscriber identity module 240 is performing the standby operation. The setting information for standby is stored in the existing memory (not shown) of the GSM and PHS dual-mode mobile phones, which means that the memory stores the setting information of the standby operation of the GSM user identification module. The memory itself can be 12 200901733 Flash Memory, Electrically Erasable Programmable Read-Only Memory 5 EEPROM or Erasable Programmable Read-Only Memory, EPROM) ° If the result of the determination is no, then the first GSM subscriber identity module standby 230' controls the first GSM subscriber identity module 230 to which it is connected 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 PHS device driver layer 223 to establish a PHS asynchronous transceiver driver module 2231 and a SIM. The PIM driver module 2232, and the PHS asynchronous transceiver driver module 2231 communicates with the GSM device driver layer 213 of the GSM control module 210 by an asynchronous transceiver (UART) specification to control the second connection with the SIM and PIM driver module 2232. The GSM subscriber identity module 240 (step S340). Please refer to FIG. 4, which is a detailed flowchart of the standby operation of the first GSM subscriber identity module in FIG. The system outputs a control command to the GSM device driver layer 213 via the GSM Application Layer 211 of the GSM control module 210 (step S331). When the GSM control module 210 transmits a control command via the GSM application layer 211, the control command is processed by the GSM protocol stack 212 and the processed control command is output to the GSM device driver layer 213. According to the control command, the original data of the first GSM subscriber identity module 230 is obtained by the GSM device driver layer 213 (Raw Data) (step S332). Thereafter, the GSM device driver layer 213 returns the original data 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 the standby mode based on the first GSM subscriber identity module 230 is entered. Please refer to FIG. 5, which is the second GSM subscriber identity module of FIG.

Detailed flow chart of standby. The system outputs a control command to the PHS asynchronous transceiver driver module 2231 via the GSM application layer 211 of the GSM control module 210 (step S341). When the system is connected to the GSM application via the GSM control module 210

When the layer 211 outputs a control command, the GSM protocol stack 212 of the GSM control module 210 processes the control command and outputs the signal, and then uses the GSM device driver layer 213 to forward the control command to the PHS asynchronous transceiver driver module 2231. When the control command is output from the GSM device driver layer 213, the control command is transmitted via the asynchronous transceiver (UART) specification. Then, the ppjs asynchronous transceiver driver module 2231 is used to parse the control command and determine whether the control command is a valid command. If it is determined to be a valid command, the SIM and pIM driver module 2232 are used to control and obtain the second GSM subscriber identity module 240. The original data is transmitted back to the GSM protocol stack 212 of the GSM control module 210 through the PHS asynchronous transceiver driver module 2231 and the GSM device driver layer 213 (step S342). 〇14 200901733 Prior to this, the PHS control module 220 is based on 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 240 to facilitate control of the second GSM subscriber identity module 240. And the transmission of data. However, since the PHS protocol stack/PIM protocol 222 operates the second subscriber identity module 240, which is a simplex serial port operation, the PHS asynchronous transceiver driver module 2231 can partially replace the PHS protocol stack/PIM protocol 222 and the PHS application layer 221. The second user identification module 240 is controlled by the SIM and ΠΜ drive module 2232. In the process of returning the original data, SIM and PIM driver module 2232

The raw data is first transmitted to the PHS asynchronous transceiver driver module 2231. The PHS asynchronous transceiver driver module 2231 transmits the original data to the GSM device driver layer 213 via a synchronous baud rate via a synchronous transceiver (UART) specification, at which time the PHS control The operation of the module 220 acts as a relay data. The GSM device driver layer 213 then transmits the raw data to the GSM protocol stack 212. Finally, the original data is processed via the GSM protocol stack 212 and the processed original data is transmitted back to the GSM application layer 211 (step S343). 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 user identification module 240 and 15 200901733 to 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 a first or second GSM subscriber identity module according to an embodiment of the present invention, which includes the following processes: acquiring and § recording a GSM subscriber The identification module 23 is either in standby or in the second GSM 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 GSM and PHS 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 the GSM and PHS dual-mode hands are restarted), the flag data stored in the memory or the standby setting information will be read to judge and drive (^ The 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.
