1 2339995 A PORTABLE TELEPHONE AND A PORTABLE TELEPHONE SYSTEM
BACKGROUND OF THE INVENTION
The present invention relates to a portable telephone having crime prevention functions.
With certain known portable telephone designs, when a portable telephone is lost or stolen, the user can contact the portable telephone service provider and ask them to set the telephone number of the portable telephone which has been lost so that it cannot be used. When the portable telephone is returned, the user can subsequently contact the portable telephone service provider again and ask them to make the telephone number of the portable telephone usable.
A portable telephone is proposed in Japanese Patent Application JP-A-312687/1998 which can be put into a crime prevention mode by inputting a personal identification number into the portable telephone, and each time the personal identification number is input into the portable telephone, the setting or release of the crime prevention mode is performed.
However, with this type of portable telephone, in the case of loss or theft, the procedures which should be followed in relation to the telephone service provider are burdensome for the user. This is despite the fact that the portable telephone is set so that it is unable to originate a call or receive an.incoming call. The problems with it include the fact that operating the portable telephone may still be possible; moreover, information such as telephone numbers and so forth stored in the portable telephone can be accessed and used.
Moreover, we have appreciated that a problem with it is that when a portable telephone has entered the crime prevention mode, this is not indicated on the portable telephone display. There is therefore the possibility that a third party will throw it away when he or she finds it unusable, rather than returning it.
SUMMARY OF THE INVENTION
The invention in its various aspects is defined in the independent claims below, to which reference should now be made. Advantageous features of the invention are set forth in the appendant claims.
A preferred portable telephone embodying the invention is described below with reference to the drawings. This preferred portable telephone has personal identification number reference means for, when information of a crime prevention ON setting code and a personal identification number are received, checking whether or not the received personal identification number coincides with a previously stored or registered personal identification number. Crime prevention mode setting means sets the telephone into a crime prevention mode when the personal identification number reference means determines that the received personal identification number does coincide with the previously stored personal identification number.
The portable telephone further comprises a key usage restriction means for setting predetermined operation keys, not including a power supply key, so as to be unavailable for use when the crime prevention mode is set by the crime prevention mode setting means.
The portable telephone further comprises message displaying means for displaying a message indicating that the portable telephone is lost when the crime prevention mode is set by the crime prevention mode setting means.
The portable telephone further comprises crime prevention mode release means for releasing the telephone from the crime prevention mode.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
Two embodiments of the present invention will now be described below in detail with reference to the drawings.
A portable telephone forming the first embodiment of the present invention is shown in Fig. 1. The portable telephone of the first embodiment comprises an antenna 1, a wireless receiving device 2, a channel codec 3, a control device 4, an operational input device 5 having a plurality of operation keys, a memory device 6, a voice generation device 7, and a display device 8 such as an LCD or the like. The wireless receiving device 2 is connected to the antenna 1. The channel codec 3 is connected to the wireless receiving device 2, to the control device 4, and to the voice generation device 7. The control device 4 is connected to the operational input device 5, to the memory device 6, to the voice generation device 7 and to the display device 8.
The operational input device 5 has operation keys such as a power supply key for switching on and off the power source, a numeric keypad for inputting numeric information, a telephone call key for telephone calling, a transmission key for transmitting the telephone number of the portable telephone, an information input key, and an information memory key for putting information into the memory device, and the like.
In the memory device 6, a crime prevention ON setting code and a personal identification number have been previously stored, and an EEPROM (Electrically Erasable and Programmable Read Only Memory) or Flash ROM are included. This EEPROM or Flash ROM has a crime prevention flag for indicating the crime prevention mode of the portable telephone. Moreover, in the memory device 6 is stored the user's contact telephone number which will be used when the crime prevention mode has been set in the portable telephone.
Furthermore, in the memory device 6 is stored a displayable message for indicating that the portable telephone is lost. For this message for displaying the loss, either a pre-determined message or a message prepared by the user can be used. Moreover, the memory device 6 stores information for the purpose of transmitting to the user by means of a voice or sound signal that a shift to the crime prevention mode has been completed.
The wireless receiving device 2 passes the crime prevention ON setting code and the personal identification number in received wireless signals from the antenna 1 via the channel codec 3 to the control device 4. When the crime prevention ON setting code and the personal identification number are received, the control device 4 checks whether or not the received personal identification number coincides with the previously stored personal identification number. When the received personal identification number does coincide with the previously personal identification number, the control device 4 turns the crime prevention flag to be in the ON condition and sets up the crime prevention mode. In this mode information cannot be deleted, even if the battery runs out.
In a portable telephone which has been shifted to the crime prevention mode, by the crime prevention flag of the memory device 6 being turned to the ON condition, the usage of some of the plurality of operation keys of the operational input device 5 is restricted. The operation keys are divided into operation keys which are available for use and operation keys which are unavailable for use.
In particular the power supply switch and the transmission key remain operational. Also, when the crime prevention mode is set, the control device 4 loads the message for displaying the loss of the portable telephone from the memory device 6, and makes the display device 8 display the message for displaying the loss, thus indicating that the portable telephone is lost.
Moreover, the control device 4 loads the information of the user's contact telephone number from the memory device 6 and makes the display device 8 display the user's contact telephone number. Furthermore, since the user's contact telephone number is stored in the memory device 6, the portable telephone has the function that by pushing the transmission key of the portable telephone an originating call signal is automatically transmitted and inputted to the user's contact telephone and a telephone call can be established. In this way it is easy for the third party to make contact with the user.
Where a portable telephone which has been lost or stolen is returned, using another telephone the user sends a crime prevention OFF setting code and the personal identification number to the relevant portable telephone. When the portable telephone receives the crime prevention OFF setting code and the personal identification number, it checks whether this received personal identification number coincides with the previously stored personal identification number or not. When the received personal identification number does coincide with the previously stored personal identification number, the portable telephone releases the crime prevention mode by turning the crime prevention flag to the OFF condition.
The operation of the portable telephone of the first embodiment will be described below with reference to Figs. 2 to 4. In the examples shown in Figs. 2 to 4, the user makes a telephone call from another telephone to the portable telephone which has been lost. When the portable telephone responds, the user transmits the crime prevention ON setting code and the personal identification number to the portable telephone.
Firstly, an example of the operation of the portable telephone will be described with reference to Fig. 2. When the user makes a telephone call, using another telephone, to the portable telephone which has been lost, the portable telephone generates an incoming call sound, automatically responds according to a number of times or for a time which has been set, transmits a response signal to the calling telephone, and enters into a telephone calling state. After the user confirms that the portable telephone has responded, the user transmits by means of a DTMF signal the crime prevention ON setting code and the personal identification number corresponding to those stored in the portable telephone for shifting the portable telephone to the crime prevention mode. When the portable telephone receives the crime prevention ON setting code and the personal identification number, the control device 4 checks whether or not the personal identification number stored in the memory device 6 of the portable telephone coincides with the personal identification number which has been sent. If the control device 4 determines that the stored personal identification number does coincide with the personal identification number which has been sent, the control device 4 turns the crime prevention flag to the ON condition. The control device 4 of the portable telephone with the crime prevention flag turned to the ON condition reads out information from the memory device 6, and the control device 4 transmits a voice or a sound signal and acknowledges to the user that the portable telephone has been shifted to the crime prevention mode.
After the user has thus confirmed that the portable telephone has shifted to the crime prevention mode, he or she terminates the call.
After the portable telephone has received the crime prevention ON setting code and has confirmed the condition of the crime prevention flag, when the line is hung up the portable telephone shifts to the waiting mode (power supply ON). The portable telephone usually shifts to the crime prevention mode, not to the waiting mode in the case where the crime prevention flag is the ON condition.
At this time, the portable telephone acknowledges to the third party that the crime prevention mode is in operation by the portable telephone loading the message for displaying the loss which is stored in the memory device 6, and making the display device 8 display the message for displaying the loss. Moreover, if the third party pushes the transmission key, origination of a call to the telephone the number of which is stored in the memory device 8 is automatically performed, and the third party can contact the user.
Next, the operation of the portable telephone will be described below in detail with reference to Fig. 3 and Fig. 4. when the power supply of the portable telephone which has been lost is the ON condition (the waiting condition), the user who has lost the portable telephone makes a telephone call to the portable telephone using another telephone. As shown in Fig. 3, firstly the control device 4 of the portable telephone determines whether or not there is an incoming call signal in step S1. When there is an incoming call signal, the control device 4 makes the voice generation device 7 generate an incoming call sound in step S2. The control device 4 determines whether or not an automatic response time has passed in step S3. In step S4, when the automatic response time has passed, the portable telephone automatically responds.
Next, the control device 4 determines whether or not the crime prevention flag is in the ON condition in step S5. In the step S5, when the crime prevention flag is not in the ON condition, the control device 4 determines in step S6 whether or not there is a crime prevention ON setting code and a personal identification number. In step S6, when no crime prevention ON setting code and personal identification number are present, in step S7, the control device 4 releases the waiting mode. Next, the control device 4 sets the telephone calling mode in step S8, and then the control device 4 determines whether the telephone calling mode is terminated or not in step S9. In step S9, when the telephone calling mode terminates, the control device 4 releases the telephone calling mode in step S10. Next, the control device 4 returns to step Sl after it sets the waiting mode in step S11.
When in the step S6 a crime prevention ON setting code and a personal identification number are present, the control device 4 checks in step S12 whether or not the personal identification number stored in the memory device 6 of the portable telephone coincides with the personal identification number which has been received. When in the step S12 the personal identification number stored in the memory device 6 of the portable telephone does not coincide with the personal identification number which has been sent, the procedure returns to step Sl. When in step S12 the personal identification number stored in the memory device 6 of the portable telephone does coincide with the personal identification number which has been sent, in step S13 the control device 4 turns the crime prevention flag to the ON condition and then transmits a confirmation sound signal in step S14. Next, the control device 4 determines whether the line is hung up or not in step S15. When in step S15, the line is hung up, the procedure returns to step S1 via the crime prevention mode setting routine (shown in Fig. 4) of step S16.
When in step S5 the crime prevention flag is in the ON condition, since its condition is subsequent to the crime prevention mode having been already set, the control device 4 determines in step S17 whether or not a crime prevention OFF setting code and a personal identification number are present. In step S17, when no crime prevention OFF setting code and personal identification number are present, since the crime prevention mode is in effect, the control device 4 determines in step S18 whether or not the transmission key is the ON condition. In step S18, the transmission key is not in the ON condition, the procedure returns to step Sl. In step S18, if the transmission key is in the ON condition, the control device 4 transmits an originating call signal to the telephone of the portable telephone user's contact telephone number in step S19, and then the procedure returns to the step Sl.
When in step S17 the crime prevention OFF setting code and the personal identification number are present, in step S20 the control device 4 checks whether or not the personal identification number stored in the memory device 6 of the portable telephone coincides with the personal identification number which has been sent. When in step S20, the personal identification number stored in the memory device 6 of the portable telephone does not coincide with the personal identification number which has been sent, the procedure returns to step Sl- When in step S20 the personal identification number stored in the memory device 6 of the portable telephone does coincide with the personal identification number which has been sent, the control device 4 sets the crime prevention flag to the OFF condition in step S21, and transmits a confirmation sound signal in step S22. Then, in step S23, the control device 4 determines whether the line has been hung up or not. When in step S23 the line is found to have been hung up, the procedure returns to step Sl.
Next, the crime prevention mode setting routine of the step S16 will be described below with reference to Fig. 4. Firstly, in step S101, the control device 4 sets the operation keys, other than the power supply key and the transmission key, so that they are unavailable for use. Next, in step S102, the control device 4 loads the information of the message for displaying the loss of the portable telephone which is stored in the memory device 6, and makes the display device 8 display the message for displaying the loss of the portable telephone, in step S103. Moreover, in step S104, the control device 4 loads the user's contact telephone number stored in the memory device 6 and makes the display device 8 display the telephone number. Next, the control device 4 determines whether or not there is an incoming call in the step S105.
In step S105, when there is no incoming call, the procedure returns to the main procedure of Fig. 3. In step S105, when there is an incoming call, the control device 4 loads the telephone number in step S106, and then, after setting the telephone calling key unavailable for use in step S107, the procedure returns to the main procedure of Fig. 3.
A portable telephone forming the second embodiment of the present invention will now be described with reference to Fig. 5. The portable telephone of the second embodiment of the present invention can deal with three situations, namely where the portable telephone is not in the waiting condition, where the power supply is in the OFF condition, and where the portable telephone is located at a position where the radio wave does not reach, and so forth. In the second embodiment of the present invention, the same reference characters are given to the same components as those of the first embodiment of the present invention.
A user who has lost their portable telephone makes a telephone call to the communication apparatus of a center set up by the telephone service provider (hereafter, referred as "the crime prevention center"), as indicated in Fig. 5. In this call the user sets up the information of the telephone number of the lost portable telephone, the crime prevention ON setting code, and the personal identification number, and then after confirming a confirmation message, which is a response signal sent from the communication apparatus of the crime prevention center indicating that the setting up of this information is terminated, the user hangs up the telephone. The communication apparatus of the crime prevention center commands the center memory apparatus in which the telephone number of the portable telephone is stored to transmit information A of the telephone number, the crime prevention ON setting code, and the personal identification number to the portable telephone, and causes the center memory apparatus to store the information of the telephone number of the portable telephone, the crime prevention ON setting code and the personal identification number. After the communication apparatus of the crime prevention center makes the center memory apparatus store the information A, the communication apparatus transmits a confirmation signal to the telephone being used by the user. This telephone transmits a disconnect signal in response to this transmission. The communication apparatus of the crime prevention center holds the information of the telephone number, the crime prevention ON setting code and the personal identification number set by the user until an access from the lost portable telephone arrives.
When the power supply key of the lost portable telephone is placed in the ON condition by the third party, or the lost portable telephone is transferred to a location where the radio wave can reach, the portable telephone transmits a location registration requirement signal to the communication apparatus of the crime prevention center and performs registration of its location, as also indicated in Fig. 5. At this time, the communication apparatus of the crime prevention center reads out the crime prevention ON setting code and the personal identification number stored in the center memory apparatus by means of the telephone number of the portable telephone uploaded to the center memory apparatus of the crime prevention center, and transmits this information B of the crime prevention ON setting code and the personal identification number to the portable telephone. When the lost portable telephone receives the information B of the crime prevention ON setting code and the personal identification number which has been sent, the control device 4 in the telephone checks whether or not the personal identification number stored in the memory device 6 of the portable telephone coincides with the personal identification number which has been sent. When the control device 4 determines that the personal identification number stored does coincide with the personal identification number which has been sent, and then after setting the crime prevention flag to the ON condition and setting up the crime prevention mode, the control device 4 acknowledges a shift to the crime prevention mode to the communication apparatus by means of a location registration termination signal. The lost portable telephone, as described above, in the crime prevention mode, restricts the usage of the operation keys, and displays the message for displaying the loss of the portable telephone. The constitution and operations of the second embodiment of the present invention are otherwise the same as with the constitution and operations of the first embodiment of the present invention.
As may be appreciated from the above description, the portable telephone can hinder a third party who picks up the portable telephone and tries to use it illegally, so that the user is under an obligation to pay the bill in the case where the portable telephone is lost or stolen, and the procedures which should be taken to the telephone service provider to make the portable telephone unavailable for use and available for use are not required.
Moreover, a third party who picks up a portable telephone can see that it has been lost.
Furthermore, the portable telephone, in addition to the effectiveness described above, will, after being shifted to the crime prevention mode, automatically originate a call to the user's contact telephone if the third party attempts to make a call by pushing the transmission key and can easily contact the user.
