DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone provided with measures against loss or theft.

[0002]

2. Description of the Related Art When a user loses a mobile communication terminal such as a mobile phone, it is very difficult to find the mobile phone in many cases because the lost location cannot be specified. In addition, there is a case where it is abused by the person who picked it up, and in that case, it costs a lot of money. Furthermore, the memory dial of the mobile phone contains information that is very important to the user, such as a telephone number and an e-mail address of an acquaintance, and that the user does not want others to know. As a portable telephone having a measure against such a problem, there is a portable telephone in which calling and browsing of a memory dial cannot be performed until a preset password is input.

[0003]

However, this function has a problem that the user has to input a password every time a call is made or the memory dial is accessed, which makes the operation troublesome. To solve this, Japanese Patent Application No. 11-25529
No. 1, when a lost mobile phone receives a specified number of calls from a phone with the same phone number within a certain period of time, the call is automatically prohibited and a misplaced message is displayed on the screen of the mobile phone. Such a countermeasure method is described, so that an unauthorized call from a lost mobile phone can be prevented without inputting a password. However, the contents of the memory dial registered in the lost mobile phone cannot be taken out, and the lost location of the lost mobile phone cannot be specified.

[0004] It is an object of the present invention to provide a countermeasure against misplacement which can obtain memory dial information by remote operation when a mobile phone or a mobile terminal is lost or stolen, and can notify the current position. The purpose is to provide a built-in mobile phone.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a portable telephone having a memory dial function and capable of transmitting and receiving e-mail, or an electronic apparatus having a memory dial function and a position recognition function. When a mobile phone that can send and receive mail receives an e-mail,
If the received e-mail contains a predetermined identifier for countermeasures against misplacement, the mobile phone is set to the dial lock state, and the list information of the memory dial is transmitted by transmitting the received e-mail. If the mobile phone also has a location recognition function, the automatic transmission of the memory dial list information and the automatic transmission of the location information of the mobile phone to the source that transmitted the received e-mail are described. To provide a mobile phone with a built-in anti-misplacement function.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a mobile phone according to the present invention.
The transmission and reception of wireless radio waves are performed via. The radio wave received by the antenna 9 is dropped into a baseband signal by the baseband unit 2, decoded by the audio processing unit 3, and transmitted to the speaker 15. Conversely, the sound of the microphone 14 is encoded by the sound processing unit 3, converted into a baseband signal by the baseband unit 2, subjected to wireless modulation by the wireless unit 1, and transmitted as a radio wave from the antenna 9. The voice communication is processed by the incoming / outgoing call processing unit 10 of the control unit 4. A call can be made using the memory dial stored in the memory dial list 13 of the storage unit 7 in addition to dial input using the numeric keys from the operation unit 5. The storage unit 7 also stores misplacement countermeasure identifier data 16 used in the present invention. The e-mail processing unit 11 controls e-mail transmission and reception and performs display processing on the display unit 6, and the misplacement countermeasure processing unit 12 performs misplacement countermeasure processing of the present invention. Also, depending on the mobile phone, GPS
It has a position information processing unit 8 for identifying the current position of the mobile phone by, for example, the following.

When a user loses a portable telephone having such a structure, the user sends a mail including a predetermined identifier for countermeasures against misplacement from the personal computer or the like to the portable telephone. FIG. 2 shows an example of the mail.
In FIG. 2, as a predetermined identifier for countermeasures against misplacement, a keyword “misplacement” and a numeric string 1234 as a password are shown. In this example, the identifier for countermeasures against misplacement is a keyword and a personal identification number. However, the identifier is not limited to a character, but may be a number or a figure. Also, the position in the mail can be specified. The data of the identifier for countermeasures against misplacement is stored in the storage unit 7 as identifier data 16 for countermeasures against misplacement.

FIG. 3 shows an operation flow of the portable telephone of the present invention. When the user learns that the mobile phone has been lost,
A mail including the identifier data for the countermeasures against misplacement is transmitted to the mobile phone. In this example, as shown in FIG.
And a numeric string 1234 that is a personal identification number. When a mobile phone receives an e-mail (STEP3
01), the mail processing unit 11 of the control unit 4 checks whether the received mail includes a keyword for countermeasures against misplacement (STEP 302). In this example, it is the character "left behind". If this character is not included (STEP
(NO in 302), processing is performed as ordinary mail without performing control for countermeasures against misplacement (STEP 307).

[0009] If a keyword for countermeasures against misplacement is included (STEP 302), it is checked whether there is a password number (STEP 303). In this example, the numeral of the personal identification number is 1234. If there is no security code (STE
(NO in P303), the misplacement process is stopped, and normal mail reception processing is performed (STEP 307). If there is a password (YES in STEP 303), control unit 4 activates misplacement countermeasure processing unit 12 and performs misplacement countermeasure processing. First, a key lock that disables key input from the operation unit 5 of the mobile phone is set (STEP 304), and calling and access to the memory dial are completely prohibited. Next, the memory dial list 13 in the storage unit 7 is sent to the sender that transmitted the mail including the countermeasure identifier (STE
P305). That is, the memory dial list 13 is transmitted to the user's personal computer. If the mobile phone has a position information processing unit 8 which is a function of identifying its own position by GPS or the like, the memory dial list 1
Following the transmission of 3 (STEP 305), the current position information is sent to the sender of the mail (STEP 306).

Next, the transmission of the memory dial list 13 (STEP 305) will be described in detail. FIG. 4 shows an example of the structure of the memory dial. The memory dial usually includes a flag indicating a registration state, a group number, a name, a reading, a telephone number, and a memo field for entering an e-maiI address and the like. The memory dial information for each case is an element of the structure. Memory dial list 1
In order to send 3 as data by mail, the misplacement countermeasure control unit 12 first converts the memory dial list 13 into a text file format and stores it. Other than the text format, other formats such as CSV format (comma delimited format) may be used. FIG. 5 shows an example of conversion into the CSV format. Then, a mail transmission destination and a title are set, and the converted memory dial data is attached to a mail text as a memory dial information file and transmitted. The user can view the memory dial again by using the received file by using spreadsheet software or memory dial editing software. By performing such processing, the user can secure the memory dial information.

Next, transmission of position information will be described. As the acquisition of the position information of the position information processing unit 8, there are a GPS method, a PHS position information service, and the like. GP
In the case of S, since the latitude and longitude of the current position are obtained,
It is easiest to send that value as is. If the position information processing unit 8 has the map data and can convert the latitude and longitude into the map data, it is desirable to transmit the converted data together with the latitude and longitude information. FIG. 6 shows an example of position transmission that has been converted and transmitted. When the location is transmitted, the mobile phone can be found immediately.

Also, the method of activating the misplacement countermeasure processing unit 12 by mail has been described. However, it is assumed that there is no mail environment at hand.
As in the embodiment of No. 5291, the misplacement function may be activated according to the number of incoming calls. In this case, the e-mail cannot be returned to the sender, so if the e-mail address of the reply destination is specified in advance, if the misplacement prevention function is required, the mobile phone will use the memory dial to the specified address. It is possible to transmit the list 13 and the position information. Even if there is no mail reception function, it is possible to automatically call a predetermined telephone number and notify the current position by voice guidance if the mobile phone has a voice synthesis function.

[0013]

The present invention has the following effects. (1) When a mobile phone is lost or stolen, memory dial information, which is important personal information lost together with the mobile phone, can be reacquired, and loss of personal information can be prevented. (2) Since the current position of the lost mobile phone can be known, discovery is facilitated.
