Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device,
More specifically, the present invention relates to a mobile phone device that enables display of various information and control of lock by a destination subaddress.

[0002]

2. Description of the Related Art Digital cordless telephones use PHP.
It is called (Personal Handy Phone), and aims to realize a system that can be used outdoors as well as indoors at homes and offices. In addition, at home, as a cordless telephone that is currently widespread,
It is used as a private cordless telephone connected to X (Private Branch Exchange: private branch exchange), and also as a mobile telephone in outdoor areas such as station squares and shopping streets, although its service area is limited. 2. Description of the Related Art In recent years, mobile phone devices such as car phones have been developed, and miniaturization and addition of various functions have been performed. The various functions include a lock function (prohibition of calling, prohibition of incoming calls, prohibition of memory call, etc.), display of various information (display on a liquid crystal display (LCD), display by sound, etc.). At present, lock setting and information input / output are performed directly from the input device of the mobile phone device.

[0003]

As described above, the size and performance of the conventional portable telephone device have been increasing. The miniaturization increases the possibility of unauthorized use by a third party due to theft or misplacement.If the mobile phone device is passed over to a third party, an unauthorized call will be made if the lock function is not set even if it has a lock function. There was a problem that was.

[0004] The present invention has been made in view of such circumstances, and in order to prevent unauthorized use of a portable telephone device when it is lost and to assist in finding the portable device, a lock setting and various displays are provided from outside the portable device. It is an object of the present invention to provide a mobile phone device that enables the following.

[0005]

According to the present invention, there is provided a portable telephone having a lock function for restricting various operations such as (1) call inhibition, call inhibition, and memory call inhibition.
In the telephone device, the ringing sub for changing the lock state
Input means for inputting address data and the like;
Therefore, storage for storing the input destination sub-address data
Means for changing a lock state stored in the storage means
The incoming sub address matching the incoming sub address data arrives
Control means for changing the lock state when received
And a telephone number in addition to the normal phone number
The operation is controlled by the destination subaddress, which is the number attached to
To be able to lock
Is provided with (2) display means for displaying a message.
On the other hand, the control means is provided for displaying data stored in the storage means.
The destination subaddress that matches the destination subaddress data is
When a message is received at the time of reception, a predetermined message is displayed on the display means.
Is displayed.

[0006]

In the portable telephone device, the lock information and the display are changed by the portable device receiving the destination sub-address during standby. If the portable device is stolen or misplaced,
In the case of passing to a third party, the lock state is changed by the destination sub-address, and illegal use is avoided by prohibiting outgoing calls, prohibiting incoming calls, changing memory / prohibiting calls, and the like. Further, a message such as contact information is displayed by a display device or a voice to assist in finding a portable device.

[0007]

Embodiments will be described below with reference to the drawings. FIG. 1 is a configuration diagram for explaining an embodiment of a mobile phone device according to the present invention. In the drawing, 1 is a CPU (central processing unit), 2 is a RAM (Random Access Memory) or EEP.
ROM (Electrically Erasable Programmable Read On)
rewritable storage device such as ly Memory) and 3 is a ROM (R
ead Only Memory), 4 is a key input section, 5 is an LCD (Liq
uid Crystal Display), 6 is a sounding body, 7 is the above 1-6
3 shows a unit of a mobile phone device other than the above.

[0008] If the portable device is passed to a third party,
The destination sub-address data for changing the lock state, display, sound generation, and the like is input from the key input unit 4 in advance, and the data is stored in the writable memory 2. When the portable device is handed over to a third party, various locks can be made by calling the portable device with the telephone number to which the destination subaddress for lock state control is added, thereby preventing unauthorized use. Similarly, the destination sub-address data for controlling display and sound generation is input from the key input unit 4 and stored in a writable memory for data 2, and the telephone number to which the destination sub-address for display and sound control is added to the portable device , The display and pronunciation can be controlled, and a third party can be notified of contact information, messages, and the like.

FIG. 2 is a flow chart for explaining the operation of the portable telephone according to the present invention when receiving a call. Less than,
Each step will be described in order. First, it is determined whether or not there is an incoming call in the portable device (step 1). If there is an incoming call, it is next determined whether or not the called number has a control destination sub-address (step 2). If there is a destination subaddress, then
It is determined whether the destination sub-address is related to lock control (step 3). If it is related to lock control, the lock state is changed (step 4). Step 3
In, if not related to lock control, then
It is determined whether or not it is related to display control (step 4), and if it is related to display control, it is displayed (step 5). In step 5, if it is not display control, then it is determined whether or not it is related to sound control (step 7). If it is related to sound control, sound is emitted (step 8).
If it is not related to the sound generation control in the step 7, the process ends. If there is no control destination sub-address in the destination number in step 2, a normal reception operation is performed (step 9), and the process is terminated.

[0010]

As is apparent from the above description, the present invention has the following effects. That is, the portable telephone device according to the present invention has a lock function for restricting various operations such as call inhibition, call inhibition, and memory call inhibition.
A portable telephone device, which is used to change the lock state.
