Description

portable electronic device

technical field

The present invention relates to a portable electronic device, and more particularly to a device generally comprising a screen display, a user input interface, a control unit and a data processing and storage device, such as a personal digital assistant (PDA), electronic translator , organizer or dictionary portable electronic device.

Background technique

The ownership of cellular digital mobile phones has grown exponentially in most developed and developing countries in the last decade. In contemporary digital cellular mobile telephone systems, subscriber mobile telephone units are connected via a base station to a mobile network operator for service connection. Before providing service to a particular mobile subscriber, the network first determines whether the mobile subscriber is eligible for service by examining the identity data communicated by the mobile unit to the network operator. In these contemporary digital telephone systems, user identity information is stored on removable memory data cards or smart cards, which, for the European digital cellular radiotelephone system known as the GSM system (Global System for Mobile communications), The card or smart card is commonly called a Subscriber Identity Module (SIM). Smart or data cards for other mobile communication standards such as CDMA (Code Division Multiple Access) or TETRA (Trans European Trunked Radio) may have different names, but their functions are basically the same. In this document, the term SIM includes SIM cards and other similar devices such as smart cards and the like.

In addition to storing user identity information such as the user's phone number and personal identification number (PIN) for mobile network identification, most SIM cards also provide additional storage space for the user to store other user-specific information such as phone number, Telephone numbers, e-mail addresses, Internet links or other contact information. The SIM for GSM complies with the standards recommended by the European Telecommunications Standards Institute (ETSI), including Rccommendations GSM 11.11 and GSM02.17, which are used for the SIM technical specification and the functional characteristics of the SIM respectively. Other related Recommendations include GSM 02.38, GSM 03.38, GSM 04.08 and other Recommendations involving numbering plans or formats.

The convenience of contemporary digital mobile phones has substantially changed the habits of many phone users. For example, many mobile phone users now tend to store all their personal contact phone information on the SIM card without any secondary or hard copy backup. Any damage or loss of the SIM card will mean the loss or destruction of all personal contact phone information.

In addition, due to intense competition from mobile phone network operators, service charges for many mobile network operators have been significantly reduced in recent years, and as a result, many users are disqualified for a variety of reasons, such as billing convenience, privacy, area coverage, service or cost savings. There are multiple or simultaneous business requirements for the same operator or different operators. Due to the diversity of service requirements, a user may store its contact information on different SIM cards. When the required number is stored on a separate SIM card, it becomes rather inconvenient if the user needs to make a phone call or make other contacts.

Furthermore, while typical digital telephone handsets have keypads for editing and entering alphanumeric information such as contact information, including names and phone numbers, mobile phone keypads typically have about 12 input keys, which means that each key must represent Four different Arabic characters to fully represent all commonly used letters and numbers. Such a simple keypad is necessary for a small, light-weight mobile phone handset, but there are problems for the user to enter or edit stored data with such a keypad. Accordingly, it would be desirable to be able to provide a device having a user input interface coupled to a "QWERTY" alphanumeric keyboard.

Therefore, it is particularly desirable to provide a portable electronic device that enables users to conveniently process SIM card data in a convenient environment. In addition, the device should preferably provide data storage means to backup SIM card data. It is further desirable that the device be able to provide backup data storage for multiple SIM cards, so that the user can selectively process data from each SIM card.

Fig. 5 shows a simplified block diagram, which mainly shows the main connection relationship of the control unit, SIM card connector, logic circuit, user input interface, screen display and peripheral equipment. The control unit (preferably a microcontroller) is mainly connected to the various components shown in Figure 1 for user interface, visual display, and data storage and transmission. The operation of the device will be explained in further detail with reference to the various modes of operation of the device. Of course, the actual operation of the device is initiated by the user by selecting the appropriate command or instruction stored in the memory of the device, recognized by the microcontroller, and sending the instruction to the microcontroller via the user interface. The interaction between the user, the input interface and the microcontroller can be achieved by those skilled in the art by reading the description of the various modes of operation of the device as described below. start up

To use the device, the user should first open the two foldable parts of the main housing and turn on the switch "ON/OFF (switch)" 147 . When the device is switched on, a main menu will appear showing a number of main applications as well as auxiliary applications associated with a particular main tool. For example, in this embodiment, the main main applications shown in Table 1 below will appear on the left side of the screen display.

Table 1 dictionary Phone Records/Directories timetable/notebook calculator clock game information other

By moving up or down the first level cursor 151 associated with the main application, a menu of auxiliary applications associated with the highlighted main tool will automatically be shown. In this embodiment, the second main application in the main menu, ie, phone records/directories is relevant and will be described in further detail. After the first level cursor 151 is moved to the "Phone Records/Directory" position, the auxiliary menu shown in the right half of the window will appear. The auxiliary tool menu includes (as an example and shown on the screen display (1) shown in Figure 6a) 1. phone number and address, 2. phone record overview, 3. SIM card file and 4. SIM card read/write . The operation of various auxiliary tools will be further introduced. SIM card read/write

When the "4. SIM card read/write" key is highlighted, the user can choose to write to the SIM card by pressing the "Enter" key and selecting the function "4. SIM card read/write" on the auxiliary tools menu. Or read data from SIM card. This selection instructs the device to start detecting the presence of the SIM card in the SIM card slot. After successfully detecting the SIM card, the device will cause the relevant data records, namely name (in Chinese or other languages) and phone number (see example below), to be downloaded into its internal memory and displayed on the screen, as shown in Figure 6b shown in the screen display (2).

At this point, the user chooses to interact with the SIM card data by instructing the device to add new entries, edit or delete existing entries. Provide a small info box near each individual record to allow the user to select a specific entry. This selection is made by highlighting the entry and then simultaneously pressing the keys "Shift" and "Select" when the secondary cursor has been moved to highlight the desired entry. After selecting a particular entry, a mark (in this example a tick "√") will be set in the box. To delete a record, the user moves the second level cursor, highlights the entry and presses the keys "Shift" and "Delete" simultaneously. If the user wishes to edit the entry, he can press the keys "Shift" and "Edit" simultaneously. Alternatively, the user may choose to add a new entry to the SIM card by pressing "New Entry" 143, then moving the second level cursor to enter a name and phone number respectively, and then pressing "Enter" to confirm the entry. After finishing deleting, editing or new entries, the data is written to the SIM card after pressing the key "Enter".

In order to backup data records, i.e. phone data or other suitable records stored in the current SIM card in this example, the user only needs to press the "Back up" key. The user will then be prompted to choose whether to store 1) selected records, or 2) all records shown on the screen display (3) shown in Figure 6c.

By highlighting the selection and pressing "Enter" to make the appropriate selection, the device will further prompt the user to identify the designated folder for data log storage. For this example, there are three folders to choose from: 1. SIM card 1, 2. SIM card 2, 3. SIM card 3, as shown in the screen display (4) shown in Figure 6d. Of course, an additional SIM card folder can be created and this folder can be renamed to the user/owner's liking.

By highlighting and pressing "Enter" to select one of the available folders, data records from the SIM card are automatically downloaded to the device's internal memory. To make the folder more recognizable, it is possible to rename the folder to give it a more meaningful name, such as the user's phone number or the name of the mobile network operator serving a particular SIM card.

In order to read and write data records between the SIM card and the device, it is necessary to first establish an initial communication link between the SIM card and the device. Generally, a standard SIM card has 8 electrical contacts whose short-circuit characteristics are shown in Table 1 as shown below. In particular, contact C1 is a supply voltage connection point (the typical range of supply voltage is between 2.7-5.0 volts). Contact C2 (RST) is used to detect whether the reset signal has been sent to the SIM card. A general SIM card is triggered by a rising edge, that is, it is reset by detecting the transition of the RST contact from LOW to HIGH. Generally, RST will remain in the HIGH state while communication between the SIM card and the device occurs. The contact C3 provides an input for a clock signal, and the clock signal is generally between 1MHz-5MHz, and determines the communication baud rate of the communication between the device and the SIM. Contact C5 (GND) provides a ground level related to the SIM. Contact C6 is connected to the supply voltage, which in this example is the same as VCC. The contact C7 is a contact for data input and output between the SIM card and the device, for example by connecting the contact to the transmitting terminal Tx or the receiving terminal Rx of the microcontroller. Contact C8 is not used and may be reserved for future use.

Before communication can take place between the SIM card and the device, the data input/output port of the SIM card controlling the communication must first be reset. Before any data communication can take place, the reset signal to the SIM must first be set to the LOW state. Before the intended communication, the supply voltage to the SIM card must be set to HIGH followed by a CLOCK signal from the control unit. At the same time, the serial port will be set to "receive" mode, and the SIM card will be reset by the rising edge of the LOW-HIGH transition of the RESET signal. After successfully resetting the SIM card, a series of data called "Answer-to-Reset" specified in ISO 7816-3 is output from the SIM card to the controller or its peripheral circuits. This data contains the type of communication protocol between the device and the SIM card and provides information to determine whether the SIM card is a positive or negative logic type. If the SIM card is a positive type, using even parity for error checking, the lower byte will be transmitted first. On the other hand, if the SIM card is of negative type, odd parity will be used for error checking, so that the upper byte will be transmitted first. In the block diagram shown in Figure 5, which shows the connection relationship of the main components, a logic IC is inserted between the SIM card and the control unit to support a negative SIM card (because the control unit (CPU) of this particular embodiment only supports positive parity). Therefore, the logic IC is inserted to supplement the deficiency of the control unit, and supports negative SIM cards that require odd parity.

Thereafter, a process of data transfer between the device and the SIM will occur, and the requested content will be transferred from the SIM to the device. When the requested data transfer has been completed, the SIM returns a status word to the device, advising that the data transfer is complete. Upon receipt of the requested data, the device will continue to process the stored data internally. In this example, the data to be transferred from the SIM card is a phone data record, including name and associated phone number. In order to access this data, the device must be set to select "Telecom Level" (Document ID: 7F10) and speed dial mode (Document ID: 6F3A). After the device is thus set up, commands are sent to the SIM card for data record transfer. Since the SIM card is formatted according to the GSM 03.38 standard, the data records will be accessed by querying the file designation "6F3A". The dialing of the name represented by the alpha designator (bytes 1-X), and the stored number represented in bytes X+3 to X+12 will be selected by the microcontroller for downloading. The table below lists the numbering format descriptions in the document with the document designator "6F3A".

Table 2 Designator "6F3A" Structure: linear fixed optional Record length: X+14 bytes update action: low Access conditions: read CHV1 (card seat confirmation) update CHV1 invalid CHV2 reset CHV2 byte illustrate M/O length 1 to X alpha identifier o X bytes X+1 Length of BCD number/SSC content m 1 byte X+2 TON and NP1 m 1 byte X+3 to X+12 Dial/SSC String m 10 bytes X+13 Capacity/Configuration Identifier m 1 byte X+14 extension record identifier m 1 byte (Note: M = Mandatory; O = Optional)

After receiving a data record from a SIM card, the microcontroller will process the data record, for example by storing the data in internal memory, grouping the recorded data according to folders specifically assigned to a particular SIM card, grouping the data The records are merged with data already stored in the internal memory with a visual marking (which associates the source of the recorded data with a specific SIM card).

When the user intends to store a data record from stored data into a folder for that particular SIM card, for example called "SIM Card 1" in this example shown in the screen display 5 shown in Figure 6e, The user simply presses the "Back up" key. Afterwards, the user chooses to store all or selected data into one of the available folders (ie SIM 1 , SIM 2 and SIM 3 ). If the user intends to store the selected information on the SIM card 1, he can highlight the key marked "Select Record" and press the "Enter" key. If the user intends to back up all phone records in the SIM card to the folder "SIM card 1", he can select the second item labeled "All Records" from the menu and store it.

After selecting the data to be stored, the folders available for storing the data will appear on the screen as shown in the on-screen display (4) shown in Figure 6d, the user highlights the specific folder by moving the cursor and pressing Hitting "Enter" will cause the data to be stored in that specific folder. SIM card file access

The user can access the records stored in the device's internal memory under the various folders by entering the main menu with the highlighted tool "Phone Directory" and selecting item 3 "SIM Card Files". This tool can be selected by moving the secondary cursor to highlight the item, then pressing "Enter" to confirm. When selected, the device will display the folders available for access or verification. In this example, folders labeled "SIM 1," "SIM 2," and "SIM 3" are available for selection. Of course, as mentioned earlier, the identities of these folders can be renamed by the user. This can be seen from the screen display (5) shown in Figure 6e.

That is, in the display content from SIM card 1, all display records are marked with "S1" in the additional box, indicating that the data record is related to SIM card file 1. If the user intends to edit the data record, he only needs to press the "Shift" and "Edit" keys simultaneously to edit. Alternatively, if the user wants to delete the highlighted record, the "Shift" and "Del" keys can be pressed simultaneously. In addition, the user can choose to backup the records of a specific folder to the current SIM card by pressing the "Backup" button. After pressing the SIM card, the device will prompt the user whether to store all records or selected records to the current SIM card in the SIM slot.

Thus, in this mode, the device has means for visually indicating the existence of data records from multiple SIM cards, wherein by accessing the individual SIM card folders or files the data records can be displayed or simultaneously provided with a flag by merging the data records, preferably All data records are displayed with a visual marker indicating the correlation between the data record and the source SIM card. Phone Data Logging Overview

Similarly, by highlighting the item labeled "Phone Directory Overview" in the secondary Tools menu, and pressing "Enter", all data records contained in that device will be displayed on that device. In this utility function, the data records already stored or installed in the device will be merged and displayed as one file, and can be arranged in descending or ascending alphabetical order or in other suitable ways. The merged data displayed on the screen display is preferably given an identifier to associate the data with the data source. In this embodiment, the designators are the labels "S1", "S2" and "S3" placed in sub-boxes corresponding to folders of available SIM cards. Utilize the display of that identifier along the name of the specific record shown in the screen display (5) as shown in Figure 6e, will tell the user the relationship between a call record and a specific SIM card folder and thus specific SIM card . As mentioned above, folders can be named according to the identity of a particular SIM card, for example, a folder can be named according to a mobile phone number or a network operator. data log entries

Similarly, new entries can be added to the device or SIM card by highlighting the entry labeled "1. Phone and Address". The user enters the details of the data record by moving the second level cursor through the available fields after completing an entry. The entry will be stored in the device's internal memory after pressing the "Enter" key. The data thus stored in the device can also be stored in the SIM card by pressing the "Back up" key.

Although several modes of operation have been described by introducing the embodiment of the telephone data record entry, it should be understood that programmers in the field, equipment or system developers, after reading the above specification, through appropriate modifications, other types of Data records can also be similarly imported into the device and transferred between the device and the SIM card. Furthermore, although the present invention has been described with reference to the above examples, it should be understood that these examples are merely to aid in the understanding of the device and are not to be construed in any way as limiting the scope of the invention. In particular, the type of portable electronic device, the type of screen display, and the type of input keyboard are appropriately modified to achieve different purposes according to application situations without affecting the spirit and essence of the present invention.
