[Industrial application field]

The present invention relates to a method for writing terminal-specific information on a wireless calling terminal, and more specifically, the present invention relates to a method for writing terminal-specific information on a wireless calling terminal, and more particularly, the present invention relates to a method for writing terminal-specific information on a terminal device such as a pager or a mobile phone, such as information such as a telephone number, serial number, and calling ID code. , we have developed a method for writing terminal-specific information for wireless calling terminals that can be easily rewritten.

[Conventional technology]

Conventionally, terminal devices such as pagers and mobile phones have stored information such as a telephone number and a calling ID code in their memory as unique information.

When such terminal devices are assembled at a factory and handed over from a dealer to a user, for example, the dealer writes unique information such as a telephone number and a calling ID code into a D.
The method used was to install an IP package fuse ROM using a socket.

If the contents of the ROM of a completed terminal were to be changed, the terminal device was brought to a dealer and the fuse ROM was replaced.

[Problems to be Solved by the Invention] The conventional devices as described above have the following drawbacks.

(1) - When changing information that has already been written, it is necessary, for example, to take the terminal device to a dealer and replace the ROM, which is costly and time consuming.

(2) To facilitate ROM replacement, it is necessary to use a DIP package ROM and socket, but this restricts the miniaturization of the device.

On the other hand, mini mold and paired chip RO are used for miniaturization.
If it is directly implemented using M, ROM cannot be replaced.

(3) Even when a nonvolatile memory is built-in, if rewriting is performed from outside the device through a connector, problems such as the reliability, size, and cost of the connector arise.

The present invention was made in order to solve the above-mentioned conventional drawbacks, and aims to make it possible to easily rewrite unique information without having to take the terminal device to a dealer or the like. It is something.

[Means to solve the problem]

In order to achieve the above object, the present invention is as follows.

FIG. 1 is a diagram showing the principle of a terminal-specific information writing method for a wireless calling terminal according to the present invention, and the present invention will be described in detail below based on this diagram.

A radio paging signal sent from a base station is received by the radio unit 2 via an antennae, and then subjected to predetermined processing to be converted into a digital signal and sent to the control unit 3.

The received signal consists of an ID code and other information, and when rewriting the terminal-specific information, a specific ID code is used as the ID code, and a memory address, data to be written, etc. are entered as the information.

The control unit 3 extracts the ID code from the received signal and compares it with the ID code stored in the storage unit 4 made of EEFROM (electrically erasable and writable non-volatile memory element) within the own terminal.

As a result, if the ID codes match, subsequent processing is performed on the content of the information, such as displaying it as a message on the display section 5.

In addition, if the 10 codes of the received signal are predetermined specific 10 codes for rewriting, an operation is performed to rewrite the contents of the EEPROM constituting the storage unit 4 according to the information (address data) sent thereafter. I do.

[Effect]

With the above configuration, the ID code is extracted from the received signal, and when it is determined that the ID code is a specific code, the terminal-specific information is rewritten using the information sent thereafter.

In this case, since the terminal specific information is stored in the EEPROM, it can be easily rewritten wherever the user is, without having to take the terminal device to a dealer or the like.

〔Example〕

Embodiments of the present invention will be described below based on the drawings. Second
4 to 4 are explanatory diagrams of a terminal-specific information writing method for a wireless calling terminal which is an embodiment of the present invention, FIG. 2 is a block diagram of the terminal device, and FIG. 3 is a diagram of a signal used for wireless calling. The configuration diagram and FIG. 4 are flowcharts when rewriting unique information.

In FIG. 2, 1 is an antenna, 2 is a radio unit that receives a radio paging signal sent from a base station, and outputs a digital signal.

3 is a control unit, 4 is a storage unit using EEPROM (electrically erasable and writable non-volatile memory element), 5
is a display section, and 6 is a write switch.

The control unit 3 also includes an ID code extraction unit 7, an information extraction unit 8, a specific ID code comparison unit 9, an ID code comparison unit 10, and a specific ID code storing a predetermined specific ID code.
A D code storage section 11 and a memory write control section 12 are provided.

The specific ID code comparison section 9 is activated and deactivated by the on/off operation of the write switch 6, and when in operation, it compares the specific ID code in the specific ID code storage section 11 with the ID code. The ID code extracted by the extraction unit 7 is compared, and if the two match, the memory write control unit 12 is notified to that effect.

The ID code comparison unit 10 compares the ID code in the storage unit 4 with
The ID code extracted by the ID code extraction section 7 is compared, and if the two match, the display section 5 is notified of this fact. In this case, the information sent thereafter is displayed as a message.

Figure 3 shows the structure of the signals used for wireless calling, where Figure 3 (A) shows the signal during normal wireless calling, and Figure 3 (B) shows the signal when rewriting terminal-specific information. .

The signal in FIG. 3(A) consists of an ID code 20 and information 2. To make a normal call using this signal, I
The D code 20 uses an ID code assigned to a terminal to be called, such as a pager or a mobile phone, and the information 21 uses information to be sent to the terminal, such as a message.

The signal in FIG. 3 (B) is a signal in the same format as the signal shown in (A) above, but the ID code section includes the I/O of each terminal.
Instead of the D code, a specific ID code 22 with a predetermined specific pattern indicating that subsequent information is a signal for rewriting is used. This specific ID code is common to each terminal.

The information 23 following this specific ID code 22 contains the required number of pairs (N pairs) of addresses 24 and data 25 of the storage section 4 made up of EEFROM for writing data.
It is a container.

PO commonly used as a wireless pager signal
When using the C3AG formant, the ID code 20 is an address code word and the information 22 is
Send using a message codeword.

Next, rewriting of the terminal-specific information will be explained along the flowchart of FIG.

When the power is turned on, the wireless section, display section, CPU of each section, etc. are cleared and initialized.

In this state, it is determined whether the write switch 6 is on. If it is off, normal radio call processing is performed.

Further, when the write switch 6 is turned on, the specific ID code comparing section 9 compares the specific ID code with the ID code extracted from the received signal.

At this time, a specific ID code that is the same as the specific ID code in the specific ID code storage section 11 is sent, and when this is detected, the memory write control section 12 is notified of this fact.

As a result, the information (address and data) sent thereafter is extracted by the information extraction section 8 and then sent to the memory write control section 12, where the data in the storage section 4 is rewritten.

For example, when rewriting terminal-specific information, the terminal side knows in advance that the rewriting process will be performed, so it turns on the write switch 6 and receives signals sent from the rewriting destination such as data. This allows such rewriting processing to be performed easily.

〔Effect of the invention〕

As explained above, the present invention has the following effects.

(1) EEPROM in the storage section to store the ID code
, the unique information can be easily rewritten without having to bring the terminal device to a dealer or the like.

(2) When manufacturing terminal devices, it is only necessary to write data after assembly and inspection are completed, so there is no need to manage each terminal one by one using numbering plans during each assembly process, and production costs can be reduced. becomes.

Additionally, it becomes possible to flexibly respond to user requests, such as changing call numbers and fixed phrases after shipping.
