The OM 500 is removable from the radio 300, and is arranged so as to be connected to the car telephone device by being set in a connecting portion 502 provided on the device when the car phone device is used.

As shown in FIG. 2, this ID EEPROM 500 includes operation lock release information 500a, wireless telephone system participation information 500b consisting of local telephone number information and a system ID related to a service area, and a wireless telephone device. Out of the plurality of attached functions, the attached function regulation information 500c distinguishes between the attached functions selected by the user of this wireless telephone device at the time of the usage contract and the attached functions that were not selected and should be regulated, and a telephone number list, etc. Personal information 500d of the user of the wireless telephone device is stored in a rewritable manner.

The operation lock release information 500a is a several-digit password, such as *12345#, for example.

[0071] The ID EEPROM 5 stores the operation lock release information 500a, which is the password *12345#.
Unless 00 is attached to the device, the operation restriction of this car phone device will not be lifted.

[0072] The wireless telephone system participation information 500b consists of local telephone number information and a system ID related to the service area.

[0073] The local telephone number information is the so-called telephone number of the car telephone.

[0074] Also, system I regarding the service area
D is information for detecting whether or not the user is within the service area of the wireless telephone system to which the user has subscribed.

Information regarding this system ID is held by the wireless telephone device and the wireless base station of the wireless telephone system, and based on the system ID information from the wireless base station, the service of the wireless telephone system to which the car telephone device has a contract is determined. It is detected whether or not the vehicle is within the range, and system control of the car phone device is performed.

[0076] In other words, if it is detected that you are within the service area, the car phone device becomes operational, and if you are outside the service area, the car phone device does not operate and "ROAM" is displayed on the display. and informs the user that he or she is out of range of the system to which he or she has a contract.

[0077] The accessory function regulation information 500c has flags written therein for determining which functions are to be activated and which are not to be activated among the plurality of accessory functions that are pre-equipped in the car telephone device.

[0078] At the time of contracting for the use of the telephone, the user selects only the desired functions, and these are written in advance as flags in the ID EEPROM.

[0079] Based on this flag, when the device is operated, the function becomes operable, and the operation of other functions not selected is restricted.

For example, as shown in FIG. 2, among the multiple attached functions, automatic redial; A=1; call-in absense; B=0; automatic answer; C=0; horn alert; D=1; If a flag is written as in the example below, the functions B and C are restricted from operation, and the functions A and D are set to be operable.

That is, the user cannot use the call-in absense function and the automatic answer function, but can use the automatic redial function and the horn alert function.

[0082] Here, some specific examples of these additional functions will be explained.

[0083] The horn alert function is one of the answering machine functions.

[0084] If there is an incoming call while the user is at a short distance from the car, this function notifies the user of the incoming call by sounding the car's horn or flashing the front lights.

[0085] The automatic answer function is a function that, when an incoming call is received, automatically puts the phone into a talking state without the user having to press the "SND" key or hook off.

The call-in absense function is one of the answering machine functions.

[0087] If there is an incoming call, the word "CALL" flashes on the display to notify that the incoming call occurred while the user was away.

[0088] In this way, the accessory function restriction information 500c is information for determining which functions are restricted in operation and which functions are operable among a plurality of accessory functions.

The user's personal information 500d is information that is used when using the car telephone device and is personally necessary for the user, such as a list of frequently used telephone numbers.

Next, the operation of the apparatus according to one embodiment of the present invention will be explained based on the operation flowchart of FIG.

After purchasing this car phone device, the user takes the ID EEPROM 500 to a predetermined telephone office or dealer, or sends it by mail, and enters the predetermined operation unlock information 500a, own telephone number, and system ID. Information 500b for participating in the wireless telephone system, and additional function regulation information 50 selected by the user.
Have them write 0c.

[0092] After completing the procedure for participating in the wireless telephone system, the car telephone device is used.

First, when this car phone device is powered on, the CPU checks whether or not the ID EEPROM 500 is set in this car phone device via the connection unit 502.
331 is detected. (Step 201) At this time, if it is not set, the operation is locked under the control of the CPU 331, and the telephone device does not operate. (Step 203) If set, ID EEPROM 5
The operation lock release information 500a stored in 00 is
The PU 331 reads the information and verifies whether it matches the correct operation lock release information set in advance. (Step 205) If the correct operational unlock information is not matched, the telephone device remains inactive. (Step 203) If the information matches the correct operation lock release information, the CPU 331 functions according to the procedure stored in advance in the ROM 334, commands the operation lock release, and the telephone device becomes usable. (Step 20
7) When the operation lock is released, the ID EEPROM5
Own phone number and system ID stored in 00
Information 500 for participating in a wireless telephone system consisting of
b and the attached function regulation information 500c are read out and temporarily stored in the RAM 335, and the CPU 331 enters a state of waiting for an instruction by the user's key input.

[0094] When the user uses the keypad 430 of the handset 400 to command a desired function from among the preset accessory functions (step 211),
The CPU 331 determines whether or not the corresponding attached function is regulated based on the attached function regulation information 500c (step 213), and if it is not regulated, the attached function is executed (215).

For example, when the user inputs "FNC" and "2" using the keypad 430, an automatic redial function is executed from among the preset additional functions corresponding to this input.

In the above example, if the automatic redial function is not preset as an accessory function corresponding to the operation of input "FNC""2", or if the automatic redial function is not pre-selected as an accessory function by the user. If not (if attached function regulation is applied)
, based on the attached function regulation information 500c stored in the ID EEPROM 500, this input "FNC""2" is ignored by the CPU 331, the attached function corresponding to the operation does not operate, and the input waiting state (step 21
Return to 1) again.

[0097] Also, if the user has already installed the ID EEPROM
The user's personal information 500d, such as a list of telephone numbers, stored in the keypad 43
When the user performs an operation to read out desired information using 0 (step 221), the corresponding information is read out and the desired information is displayed on the liquid crystal display 452 (step 221).
Step 225).

For example, using the keypad 430, select "RC
If you enter "L""2", the second registered phone number "03" in the phone number list as shown in 500d in Figure 4 will be displayed.
-3123-4567” is displayed on the liquid crystal display 452.

Furthermore, when the user wishes to register a new telephone number, he/she can use the keypad 430 to enter, for example, "ST".
When you enter the registration command and the phone number you want to register, such as ``O'', ``10'', and ``765-4321'' (Step 22
7), Phone number "765-4321" is EE for ID
It is stored in an empty location in the telephone number list of PROM 500, for example, in the 10th position (step 229).

[0100] When the user confirms that the series of operations has been completed (step 231), the user removes the ID EEPROM 500 from the car telephone device, and
The series of operations ends.

[0101] Also, if this user borrows another person's car phone device to make a call, if it is the same type of device as his own car phone device, he must use his own ID EEPR.
You can set up the OM500 and use it in the same way as your own device.

[0102] When the owner of the car phone device changes, the new owner signs a new contract with the telephone office, then removes only the ID EEPROM 500 from the car phone device and takes it to the designated telephone office or dealer. Or, send it by post, rewrite the information 500b for participating in the wireless telephone system consisting of your own telephone number and system ID, and the attached function regulation information 500c, and have them return it.

[0103] The ID EEPROM 500, which has completed the procedure for participating in the wireless telephone system, is installed in the car telephone device and used.

[0104] As described above, the ID of this car phone device
When the EEPROM 500 is installed in a car phone device, the operation of the device is unlocked, and the various information stored inside the EEPROM 500 necessary for operating the car phone device is sent to the CPU 331 etc. to operate the car phone device. Activate various functions.

[0105] When the user is not using this car phone device, it is designed in such a way that the user can remove it from the car phone device and carry it around.

[0106] This achieves various effects and advantages as described above.

It should be noted that the above-described operation flowchart and the operation procedure explained based thereon show a typical example of the operation procedure of this apparatus, and in reality, there are various operation procedures depending on conditions such as the procedure of use.

[0108]
