Description of the Invention: [Technical Field] The present invention relates to a method for controlling a dual PHS subscriber identity module, and more particularly to a method for controlling a dual pjjs subscriber identity module for a PHS and CDMA 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 of mobile phones need to be able to switch to different standard systems, mobile phone communication companies have developed mobile phones with dual-mode systems, such as PHS and The CDMA system is one of the representatives.

Please refer to Figure 1 for the prior art PHS and CDMA dual mode system architecture. In the operation mode of the architecture, the PHS control module 110 can control the PHS subscriber identity module 130. The PHS subscriber identity module 130 can be electrically connected to a PIM (Personal Identity Module) card. In addition, the PHS control module 110 can also control the CDMA subscriber identity module 140 through the CDM control module 120. It transmits a control command using the PHS Application Layer 111. The control command is transmitted to the PHS 6 200901738 PHS Device Driver Layer 113 via the PHS Protocol Stack 112. The PHS device driver layer 113 then transmits a control command to the CDMA device driver layer 123 of the CDMA control module 120 through a Universal Asynchronous Receiver/Transmitter 'UART specification. Finally, the CDMA protocol machine (CDMA) The Protocol Stack)/UIM protocol 122 passes this control command to the CDMA Application Layer 121 of the CDMA Control Module 120. The CDMA 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 CDMA device driver layer 123 through the CDMA protocol stack/UIM protocol 122 and the CDMA user identification mode is read. Raw data of the group 140 (Raw Data), the CDMA subscriber identity module 140 is electrically coupled to a [JIM (User Identity Model) card. The original data of the CDMA subscriber identity module 140 is then passed back to the CDMA application layer 121 via the UIM Protocol of the CDMA control module 120, thereby acting as a response to this control command. Finally, the CDMA application layer 121 calls the CDMA device driver layer 123 to transmit the original data to the pHS device driver layer 113 through the asynchronous transceiver (UART) specification, and transmits the original data back to the pHS application layer ηι through the PHS protocol stack ,2, by the PHS application layer. 111 processes the raw data returned. However, the prior art system has an inevitable deficiency, that is, such a pHS and CDMA dual-mode mobile phone cannot be applied to a dual PHS user identification module. 7 200901738 » » 'user' means a user who has a dual PIM card . Due to the PHS and CDMA dual-mode mobile phone • The prerequisite for using the dual-mode function is that the user must have a PIM card and a UIM card (including the chip built in the mobile phone or 1C) with the corresponding PHS number and CDMA number. . If the user wants to use two PIM cards corresponding to the PHS number, they still need to buy an additional mobile phone that can be inserted into the PIM card. Therefore, it is unable to meet the needs of users who have dual PHS numbers without applying for the CDMA CDMA number, thereby reducing the practicability of the PHS and CDMA dual-mode mobile phones. [Invention] In view of the above, in order to solve the above problems, the present invention proposes a pHS (Personal Handy-phone System) and a CDMA (Code Division Multiple Access) system.

The PHS and CDMA dual-mode mobile phone have a phs control module and a PHS control module. After the PHS and CDMA dual-mode mobile phones are initialized by the execution system, it is judged whether one of the second phs user identification modules connected by the CDMA control module stands by. If the result of the determination is yes, the second user identification module stands by, and the dual-mode mobile phone establishes a CDMA Universal Asynchronous Receiver/Transmitter connected to each other in a CDMA device driver layer (CDMA Device Driver Layer). 8 200901738

Driver ' CDMA UART Driver ) and a PIM and UIM driver module, and the CDMA asynchronous transceiver driver module communicates with the PHS device driver layer of one of the PHS control modules by the asynchronous transceiver (UART) specification to control the piM and UIM driver modules. The second PHS user identification module connected to the group. If the result of the determination is no, the first PHS user identification module stands by, and the dual mode mobile phone controls the first PHS user identification module connected by the PHS control module. In addition, when the PHS and CDMA dual-mode mobile phones are in the standby mode of the first PHS user identification module or the PHS user identification module, the PHS user identification module can be acquired and recorded or identified by the second PUS user identification module. Control commands or setting information for module standby. Then reset the system to perform the system initialization steps. The first PHS user identification module or the second phs user identification module is stored by using a flash memory, an EEPR0M or an EPROM. However, the first PHS subscriber identity module is coupled to a first PIM (Personal Identity Module) card for reading data of the first PIM card. The second PHS subscriber identity module is electrically coupled to a second PIM card for reading data of the second PIM card. The invention has the functions that cannot be achieved by the prior art, that is, the PHS user identification module of two different numbers can be configured on the pHS and the CDMA dual-mode mobile phone, that is, the PIM card corresponding to the two PHS numbers can be electrically coupled. In addition to the control and data transmission of the first PIM card electrically coupled to the first PHS subscriber identity module, the PHS control module can further transmit the CDMA asynchronous transceiver driver module and the piM and UIM driver module. The control and data transfer are performed on the second PIM card electrically coupled to the second pHS user identification 9 200901738 module. Because (4) users with dual PIM cards can also easily control the Shuangqing number and freely choose to wait for different PHS livers, and do not need to make hardware (4) major changes. In addition, (: DMA control module is only equivalent to the function of transfer data, without the need for CDMA protocol stack and UIM protocol, so it can reduce the complexity of the control and its performance.); The development time and cost of mobile phone manufacturers also meet the needs of modern people seeking new changes. At the same time, they can satisfy the needs of business people and individualized enthusiasts. [Embodiment] The features and implementations of the present invention are shown in the accompanying drawings. The preferred embodiment is described in detail below. Please refer to FIG. 2, which is a system architecture diagram of the first and second pjjs user identification module embodiments of the present invention. The system includes a PHS (Personal Handy-phone System, The personal handy phone system) control module 210, a CDMA (Code Division Multiple Access) control module 220, a first PHS user identification module 230 and a second PHS user identification module 240. The PHS control module 210 includes a PHS Application Layer 211, a PHS Protocol Stack 212 and a PHS Device Driver Laye. r) 213, and the CDMA control module 220 includes a CDMA application layer (CDMA), a CDMA protocol stack, a UIM protocol 200901738, and a CDMA device driver layer (CDMA Device). Driver Layer 223, and a CDMA Universal Asynchronous Receiver/Transmitter Driver > CDMA UART Driver 2231 and a PIM (Personal Identity Module) are established in the CDMA device driver layer 223. The UIM (User Identity Model) driver module 2232. The 'PHS device driver layer 213 is electrically coupled to the first PHS subscriber identity module 230; the CDMA asynchronous transceiver driver module 2231 is associated with PIM and UIM. The driving module 2232 is connected to and connected to the phs device driving layer 213; and the second PHS user identification module 240 is electrically coupled to the PIM and UIM driving module 2232. The system is based on the first PHS user stored in the dual mode mobile phone. The identification module 230 or the setting information of the standby PHS user identification module 240 is standby, so that the PHS application layer 211 of the PHS control module 210 sends a corresponding control command. PHS via the device driver layer 213 to control the first user identification PHS module 230 for data transfer with the actuator. Alternatively, the pHS control module 21 drives the layer 213 and the CDMA asynchronous transceiver module 2231 via the pHS device to transmit control commands to the PIM and UIM driver module 2232 to control the operation of the second PHS user identification module 240. With data transfer. When the PHS control module 21 controls the second PHS subscriber identity module 240, the CDMA asynchronous transceiver driver module 2231 controls the PIM and UIM driver module 2232 to perform a simple serial port operation 200901738. The module 2231 can replace some functions of the CDMA application layer 221 and the CDMA protocol/UIM protocol 222, so there is no need to utilize the CDMA application layer 221 and the CDMA protocol stack/UIM protocol 222. In this example, the first PHS subscriber identity module 230 is electrically connected to a first PIM card (not shown). The second PHS subscriber identity module 240 is electrically coupled to a second PIM card (not shown). Secondly, the transmission message between the PHS device driver layer 213 and the CDMA asynchronous transceiver driver module 2231 is transmitted through an asynchronous reception.

The Universal Asynchronous Receiver/Transmitter (UART) specification performs control commands and data aggregation and transmission. 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 PHS and the CDMA dual mode mobile phone are powered on or reset. It is judged whether or not one of the second pjjs user identification modules 240 connected by a CDMA control module 220 is on standby (step S320). The system retrieves the setting information for standby to determine whether the standby operation is performed by the second PHS subscriber identity module 240. The standby setting information is stored in the existing memory (not shown) of the PHS and CDMA dual-mode mobile phones, which means that the memory stores the setting information of the standby of the PHS user identification module. The memory itself can be Flash Memory, Electrically Erasable Programmable Read-Only Memory (EEPROM) or erasable programmable read only memory (Erasable 12 200901738)

Programmable Read- Only Memory, EPROM). If the result of the determination is no, then a first PHS subscriber identity module standby 230 is controlled by a PHS control module 210 to control the first PHS 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 PHS subscriber identity module 240 stands by, and a CDMA device driver layer 223 establishes a connection between the CDMA asynchronous transceiver module 2231 and a PIM. The UIM driver module 2232, and the CDMA asynchronous transceiver driver module 2231 communicates with the PHS device driver layer 213 of the PHS control module 210 by an asynchronous transceiver (UART) specification to control the second connection with the PIM and UIM driver module 2232. The phs user identification module 240 (step S340). Please refer to FIG. 4, which is a detailed flowchart of the standby of the first PHS subscriber identity module in FIG. The system outputs a control command to the phs device driver layer 213 via the PHS Application Layer 211 of the PHS control module 210 (step S331). When the PHS control module 210 transmits a control command via the phs application layer 211, the control command is processed by the PHS Protocol Stack 212 and the processed control command is output to the PHS device driver layer 213. According to the control command, the raw data (Raw Data) of the first PHS subscriber identity module 230 is obtained by the phs device driver layer 213 (step S332). Thereafter, the PHS device driver layer 213 then transmits the original data to the PHS protocol stack 212 and processes the original data via the PHS protocol stack 212 (step S3 3 3). Finally, the processed raw data 13 4 « 200901738 is passed back to the PHS application layer 211 (step S334). Thereby, the PHS control module 210 is controlled to read and control the data of the first PHS user identification module 230, and enters the standby mode with the first PHS user identification module 230 as the main mode.

Please refer to FIG. 5, which is a detailed flowchart of the second PHS subscriber identity module standby in FIG. In step S340, the system outputs a control command to the CDMA asynchronous transceiver driver module 2231 via the PHS application layer 211 of the phs control module 210 (step S341). When the system passes the PHS of the PHS control module 210 (the application layer 211 outputs a control command, the PHS protocol stack 212 of the PHS control module 210 processes the control command and outputs it, and then uses the pHs device driver layer 213 to transfer the control command to the CDMA. The asynchronous transceiver driver module 2231. When the control command is output from the PHS device driver layer 213, the control command is transmitted via the asynchronous transceiver (UART) specification. Then, the CDMA asynchronous transceiver driver module 2231 is used to parse the control command and determine the control command. Whether it is a valid command, if it is determined to be a valid command, the PIM and UIM driver module I 2232 are used to control and obtain the original data of the second PHS subscriber identity module 240, and the CDMA asynchronous transceiver driver module 2231 and the PHS device driver layer are used. 213 returns the original data to the PHS protocol stack 212 of the PHS control module 210 (step S342). Prior to this, the CDMA control module 220 configures its operating clock and operating voltage to conform to the second PHS user according to the control command. Identifying the electrical characteristics specification of the module 240 and initializing the second PHS subscriber identity module 240 to facilitate control of the second PHS subscriber identity module 240 Data transmission 14 200901738. However, since the CDMA protocol stack/UIM protocol 222 operates the second subscriber identity module 240 to be a simplex serial port operation, the (^) asynchronous transceiver driver module 2231 can partially replace the CDMA protocol stack/ The UIM protocol 222 and the CDMA application layer 221 control the second user identification module 240 through the piM and UIM driver module 2232. In the process of returning the original data, the PIM and UIM driver module 2232 first transmits the original data to The CDMA asynchronous transceiver driver module 2231, the CDMA asynchronous transceiver driver module 2231 transmits the original data to the PHS device driver layer 213 through a synchronous baud rate via a synchronous transceiver (UART) specification, at which time the operation of the CDMA control module 220 The function is to transfer the data. The PHS device driver layer 213 then transfers the original data to the PHS protocol stack 212. Finally, the raw data is processed via the PHS protocol stack 212 and the processed raw data is passed back to the PHS application layer 211. (Step S343), the PHS application layer 211 processes the original data returned, and further completes the initial control of the PHS application layer 211 to the second PHS user identification module 240, and simultaneously enters The second phs user identification module 240 is in the main standby mode, and the user can control the second PHS user identification module 240 through the phs application layer 211 and transmit data. Referring to FIG. 6, it is the present invention. A flow chart for selecting and recording a standby embodiment of the first or second PHS subscriber identity module in an embodiment includes the following processes:

The first PHS user identification module 230 is acquired and recorded or is in standby with the second PHS 15 200901738 user identification module 240 (step S410). This step has a number of different approaches. The most common practice is to record flag data and store standby settings. When the user uses the PHS and CDMA dual-mode mobile phone to switch or select the control command of the first PHS user identification module 230 or the second PHS user identification module 24, the system will retrieve the control command and control according to the control. The command includes information to write a flag data or store the standby setting information of the first PHS user identification module or the second PHS user identification module that the user wants to use in the memory. Reset the system (step S420) ‘When the system is reset (or the pjjs and CDMA dual-mode phone are rebooted), will the flag data stored in the memory or the standby setting information be read to judge and drive? The control module 21 reads the original data of the first PHS user identification module 230 or the second PHS user identification module 240 to enter the first pHS user identification module 23 or the second pHS user identification module 240. Standby mode. In summary, the system and method for controlling dual PHS user identification modules using PHS and CDMA dual-mode mobile phones provided by the present invention can be carried out without changing the hardware, through the PHS control module, and the CDMA asynchronous transceiver driver.
