g system etc. are known. Each of these systems has one telephone number corresponding to each service area, and does not allow the same terminal to use a plurality of telephone numbers in the same service area.

Thus, in the conventional car telephone system,
The telephone number that one mobile station device can use within the same service area is usually limited to one telephone number. According to such a conventional car telephone device, the user is forced to make a call using the same telephone number regardless of whether the content of the call is private or public, and the public telephone of a company or the like is unavoidably used for private use. There was the inconvenience of having to use it.

Considering this from the viewpoint of call charges, regardless of whether the content of the call is public or private, the charge is made with one registered telephone number. There was also the inconvenience that the individual telephone charges had to be replaced. Especially in the United States, even if a call comes in, a system is charged on the receiving side (AirCha
rge)), and in such a system, there were times when unsolicited charges were made for undesired incoming calls.

[0005]

As described above, in the above-mentioned conventional radio telephone system, since one mobile station device has only one telephone number that can be used, it is possible to use the telephone number separately for public use and private use, for example. I could not do it and it was inconvenient. Further, with respect to the call charge, since the above-mentioned one telephone number is charged for all calls of the mobile station device, there is a problem that the company or the like has to pay the individual telephone charge.

The present invention eliminates this problem and provides a radiotelephone system in which one mobile station device can be used properly depending on whether it is public or private, and an individual charging system can be realized according to the use. The purpose is to provide.

The outgoing / incoming call control means is characterized in that when there is a telephone number stored in the incoming call permission number storage means, it controls so as to prohibit an incoming call other than the telephone number.

Further, the third invention of this application is the above first invention.
Alternatively, in the second invention, the mobile station device further includes a telephone number designating unit that designates a telephone number used for calling, and a calling number storage unit that stores the designated telephone number as a calling number. The outgoing / incoming call control means is characterized in that, when there is a telephone number stored in the calling number storage means, the telephone number is preferentially captured and a call is made.

[0010]

According to the present invention, a plurality of telephone numbers are registered for one mobile station device. This registration is performed, for example, by storing a plurality of telephone numbers corresponding to a unique serial number that identifies the mobile station device.

The switching center side recognizes whether or not the mobile station device is correctly registered at the time of calling or receiving a call by a combination of a plurality of telephone numbers corresponding to the serial number of the mobile station device. However, as long as the serial number and the telephone number used at that time satisfy the above registration conditions, the operation is performed so as to respond to the call origination or call termination processing by the telephone number. As a result, a plurality of telephone numbers that can be used within the same service area can be set for one mobile station device.

Further, according to the present invention, each mobile station device sets an incoming or outgoing telephone number restriction mode as required, and a telephone number to be used for incoming or outgoing calls is selected and prepared in advance. Certain incoming or outgoing assigned number storage means (NAM:
Number Assignment Module).

Further, when making an incoming call, each mobile station device controls to reject an incoming call with a telephone number other than that stored in the incoming NAM. When making a call in the calling telephone number restriction mode, the telephone number stored in the calling NAM is preferentially captured and called.

With this control, incoming calls can be restricted by selecting any of the plurality of telephone numbers, and outgoing calls can be made by designating any of the telephone numbers. Therefore, in the present invention,
Depending on the selection of each telephone number, it is possible to set, for example, two types of usage, one for public use and one for private use, to one mobile station device.
In this case, the exchange side charges for each selected telephone number, and the call charge can be distinguished according to the above usage.

Next, an example of the connection control operation of the automobile telephone device 100 having such a configuration will be described in detail with reference to the flowchart shown in FIG.

Turning on / off the switch unit 470 of the telephone 400
When the off switch 474 is turned on, the power source unit 390 turns on the power to each unit (step 601).

FIG. 7 is a flow chart showing the detailed operation at that time. That is, when the power is turned on, the respective parts are reset (step 701), and when the reset of the respective parts is completed, for example, the entire surface of the liquid crystal display 452 blinks or a predetermined ringing sound is output from the speaker 492. The user is notified that the reset is complete.

Thereafter, it is confirmed whether or not the lock state is set (step 702). The locked state is a state in which no further operation is performed unless a predetermined key operation is performed on the key portion 430 to prevent unauthorized use.

When the lock state is set, the "LOOK" display lights up on the liquid crystal display 452 (step 703). On the other hand, when the lock state is not set, the "NO SVC" display is turned on in the liquid crystal display 452 (step 704).

Next, when such a reset is completed,
Initialization is performed (step 602). FIG. 8 is a flowchart showing the detailed operation at that time. That is, the audio / control unit 300 in the wireless device 300
Causes the demodulator 312 to scan the D channel (step 801) to obtain received electric field strength information. Then, the D channel having the highest electric field strength among the D channels is received. At this time, information on the D channel having the next highest electric field strength among the D channels is also obtained.

Thereafter, the control signal processing unit 338 establishes bit synchronization and frame synchronization, that is, word synchronization with the D channel being received (step 802) and obtains system information from the base station via this D channel (step 802). 803). As described above, such system information includes the system number indicating the service area in which the base station exists. And such information is stored in the RAM 335.
Stored in.

When the word synchronization or the system information reception described above is not performed even after a predetermined time has passed, the D channel having the next highest electric field strength is used (step 80).
4), the same is done. In this case, if the word synchronization or the reception of the system information is not performed even after a predetermined time has passed, the D channel scan is performed again in the demodulator.

When such initialization is completed, a similar scan is performed on the P channel (step 603). FIG. 9 is a flowchart showing the detailed operation at that time. That is, the audio / control section 330 in the wireless device 300 obtains the received electric field strength information by causing the demodulator 312 to scan each P channel (step 901). Then, the P channel having the highest electric field strength among the P channels is received. At this time, information on the P channel having the next highest electric field strength among the P channels is also obtained.

After that, the control signal processing unit 338 establishes bit synchronization and frame synchronization, that is, word synchronization with the P channel being received (step 902), and obtains system information from this P channel (step 903). Then, the standby reception state is set under the environment of the system information obtained here (step 904).

When the word synchronization or the system information reception described above is not performed even after a predetermined time has elapsed, the P channel having the next highest electric field strength is used (step 904).
The same is done. In this case, if word synchronization or system information reception is not performed even after a predetermined time has elapsed, initialization is performed again (step 602). Also, if the position information cannot be obtained from the system information, the initialization is performed again (step 602).

Now, the standby reception state described above (step 6)
In 04), the CPU 331 collates the system information stored and held in the RAM 335 with the own device information registered in the IDROM 370, and, for example, handles the subsequent incoming call as follows according to the collation result (see FIG. 6
reference).

That is, in the present invention, for example, IDRO
A plurality of telephone numbers corresponding to the serial number of the terminal itself are stored in the M370, and the CPU 331 receives the incoming calls by all the telephone numbers registered here unless the incoming call telephone number designation mode described later is set. Works to accept. On the other hand, when the incoming call telephone number designation mode is set, the CPU 331 controls such that the incoming call is accepted only by the telephone number designated in that mode.

Details of this operation will be described with reference to FIG. 6 again. That is, in the mobile telephone device 100, when the incoming call request is recognized in the standby state (step 604) (YES in step 605), whether or not the incoming call telephone number designation mode is being set for the incoming call. Is determined (step 606). Here, when it is recognized that the incoming call telephone number number designation mode is being set (step 606Y).
ES), and then it is determined whether or not the called telephone number at this time is registered in a called NAM (Number Assignment Module) described later (step 607). If the incoming telephone number is not registered in the incoming NAM (step 607 NO), control is performed to reject the incoming call request (step 608).

On the other hand, the called telephone number is the called NAM.
If it is registered in (step 607 YES), the incoming call processing by the incoming call telephone number is accepted (step 6).
09). If the called telephone number designating mode is not set in the judgment of step 606, the processing of step 607 is skipped as long as the called telephone number is one of the above-mentioned telephone numbers. It responds to the incoming call processing with a condition.

Next, a registration form of a plurality of telephone numbers in the device 100 of the present invention for enabling the above control and a method of designating a telephone number in which an incoming call is permitted will be described with reference to FIG.
0 and FIG. 11 will be described.

First, in the present invention, the IDR of the wireless device 300 is
Mobile station information is stored in the OM 370, for example, in a manner as shown in FIG. That is, this mobile station information is one in which three telephone numbers (1) to (3) are registered in the mobile station device in correspondence with the serial number unique to the manufacturing stage.

The mobile station device selects any one of the registered telephone numbers when receiving or making a call, and carries out the receiving or calling process based on the selected telephone number. On the other hand, on the side of the base station, when the incoming or outgoing call is made, the registration condition is met while confirming that the mobile station device is a correctly registered terminal by the combination of the serial number and the corresponding three telephone numbers. As far as possible, the normal connection process is performed even when one or more telephone numbers correspond to the mobile station device.

As a result, in the present invention, as long as the later-described called telephone number designation mode is not set,
Each mobile station device can talk with the other party by using any of all the telephone numbers registered in the own terminal.

On the other hand, the mobile station device side has a use restriction function as described below with respect to the operation of the three telephone numbers registered in its own terminal. One of the functions is a function of regulating the incoming telephone number to any of the above three telephone numbers. To activate the function, the incoming telephone number designation mode process shown in FIG. 11 is performed. To deal with.

That is, when this called telephone number designation mode processing is performed, the mobile station apparatus side must set the mode. Here, it is assumed that the mode setting can be performed, for example, by a combination operation of the function key + # key + numeric keypad (80) on the keypad of the key unit 430 of the handset 400b.

In the wireless device 300, the CPU 331
It is monitored whether or not the key operation of the above combination is performed (step 1101), and when the key operation is performed, a beep sound is generated to notify the establishment of the mode setting (step 1102).

Thereafter, from that state, it is sequentially determined whether or not each of the "0", "1", "2", and "3" keys is pressed on the keypad (step 110).
3 to step 1106). It should be noted that each of these keys is a numeric keypad that is assigned in advance in correspondence with each telephone number in order to specify and register each telephone number in the IDROM 370 shown in FIG.

If the "0" key is pressed (YES in step 1103), an incoming multi-NAM (Number Assignment Module) storing all three telephone numbers (1) to (3) in the IDROM 370 is created. (Step 1107). This multi-NAM can be secured in the RAM 335 in the wireless device 300, for example.

If any of the "1", "2", and "3" keys is pressed without pressing the "0" key, the telephone numbers 1 and 2 corresponding to these keys are pressed. ，
(3) is read from the ID ROM 370 and registered in the telephone number area of the incoming NAM in the RAM 335 (steps 1108, 1109, 1110).

Similarly, the present invention also has a function of making a call by designating any one of the three telephone numbers registered in the terminal when making a call. In order to activate the calling function of such a condition, the calling telephone number designation mode process shown in FIG. 12 is used.

That is, it is assumed that this calling telephone number designation mode is set by operating the combination key of the function key + # key + the ten key (70) on the keypad of the handset 400b.

In the wireless device 300, the CPU 331
Whether or not the combination key operation is performed is monitored (step 1201), and when the key operation is performed, a beep sound is generated to notify the establishment of the mode setting (step 1202).

Thereafter, from that state, it is sequentially determined whether or not each of the "1", "2", and "3" keys is pressed on the keypad (steps 1203 to 1205). If the "1" key is pressed (YES in step 1203), the telephone number area of 1 corresponding to the "1" key read from the IDROM 370 is stored in the telephone number area of the calling NAM secured in the RAM 335. (Step 1206).

When the "2" and "3" keys are pressed, the telephone numbers {circle over (2)}, {circle around (3)} corresponding to these keys are pressed.
From the ID ROM 370 and stored in the telephone number area of the calling NAM in the RAM 335 (steps 1207 and 1208).

Through the above-described incoming call or outgoing call telephone number designation mode processing, in the RAM 335, for example, the NAM (incoming call NA) in which incoming and outgoing call control information as shown in FIG. 13 is stored.
M and calling NAM) can be created. In the case of this example, the outgoing / incoming call control information is:
All the telephone numbers of 3 can be used, and it means that the telephone number of 3 has been designated at the time of calling.

Of the controls using this NAM information,
Incoming call control is as described above. That is, in the processing after step 606 shown in FIG.
The CPU 331 sets the called telephone number designation mode,
Incoming calls with telephone numbers not registered in the incoming NAM are rejected (step 607 → step 608), and only incoming calls with the registered telephone numbers are answered (step 607 → step 609).

By appropriately selecting the telephone numbers for which the incoming call is permitted by using this incoming call telephone number designation mode, a plurality of telephone numbers possessed by the own terminal are made to correspond to a certain use condition, for example, public use and private use. You will be able to use it to a certain extent.

On the other hand, at the time of calling, the CPU 331 preferentially captures the telephone number stored in the calling NAM under the setting of the calling telephone number designation mode and performs the calling processing. This allows
It is possible to make a call by designating one of the above-mentioned telephone numbers of the own terminal.

As an example of the calling process, the operation when a call is made from the standby reception state (step 604) will be described with reference to the flowchart shown in FIG.

First, in this calling operation, the key unit 43
When there is a call request by input from 0, a timer for counting the call acceptance time is set (step 1401).
The set time is, for example, 12 seconds.

Thereafter, the demodulator 312 scans the A channel with the base station in order to establish a communication line or the like (step 1402) to obtain the received electric field strength information.
A of these A channels, which has the highest electric field strength,
The channel is ready to be received. At this time, information of the electric field strength A channel next to the A channel is also obtained.

Next, it is confirmed whether or not the user has the intention of making a call (step 1403). The call is made by the user pressing the "RCL", "X", "Y" (X and Y are numeric keys) in the case of the numeric keys or speed dial of the key section 430 This is done by pressing the "SEND" key after setting the telephone number of. In making the call, in particular, in the present invention, the calling telephone number designation mode described above can be selected as necessary. If the user has no intention of calling,
Initialization is performed again (step 602).

Thereafter, the control signal processing unit 338 establishes bit synchronization, frame synchronization, and word synchronization with the A channel received, and obtains system information from this A channel (step 1404). If word synchronization cannot be achieved, the same operation is performed by the control channel having the next highest electric field strength (step 140).
5). In this case, if word synchronization cannot be achieved, initialization is performed again (step 60).
2).

At this point, it is again confirmed whether or not the user has a calling intention (step 1406). This is performed by using the "SEND" key as in the case described above. If the user does not intend to make a call, the initialization is performed again (step 602).

Thereafter, the car telephone system 100 acquires a predetermined transmission control channel based on the above system information (step 1407). If the transmission control channel cannot be acquired, the initialization is performed again (step 602). Also, if the acquisition of the outgoing control channel is delayed (step 1
408), the intention of calling is confirmed again (step 1406).

When it is determined that the user has the calling intention and the calling control channel is captured, it is then determined whether or not the calling telephone number designation mode is set (step 1409). Here, if the calling telephone number designation mode is not set, any one of the plurality of telephone numbers registered in the IDROM is selected (step 1410). On the other hand, when the calling telephone number designation mode is set, the calling NAM of the RAM 335 is set.
Select a phone number stored in (step 14
11).

Thereafter, the car telephone system 100 uses this selected telephone number to send out a calling signal containing at least the telephone number information of the destination set by the user on the transmission control channel captured in step 1407 (step 1).
412).

Thereafter, the response signal to the call originating from the base station included in the system information of the A channel is received (step 1413) and it is recognized that the call originating signal is transmitted. It should be noted that the base station side establishes a line connection with the other party based on the telephone number included in the calling signal.

Then, the communication channel designated by the system information of the A channel from the base station side (step 141
In 4), the call becomes available. When the call channel cannot be obtained, the initialization is performed again (step 602).

As described above, according to the present invention, the call can be made at any of the plurality of registered telephone numbers, and the called number designation mode is set as necessary to set the called N number.
An AM is created and an incoming call with a telephone number other than that stored in the incoming NAM is rejected. From this, by using the present automobile telephone device 100, for example, the following system operation becomes possible.

For example, in the case of having two telephone numbers, the telephone number of (1) is assigned for public use and the telephone number of (2) is assigned for private use. Then, regarding the operation of the incoming call telephone number designation mode described above, when selecting one of them from the keypad, for example, the function key +
The "0" key can use two telephone numbers, the function key + "1" key can use the telephone number of 1 and the function key +
The condition that the "2" key can use the telephone number (2) is determined.

According to this condition, in the normal state,
Two phone numbers can be used through the operation of the function key + "0" key, and on holidays, only the private phone number can be used through the operation of the function key + "2" key. It will be possible.

Further, according to the present invention, the telephone number designation call can be made through the calling telephone number designation mode as described above.
When making a call, it is possible to use it as a public or private one. With regard to this call, the charges are made for each specified telephone number, so even if it is a company telephone, it is possible to manage the charges efficiently, such as allowing the individual to pay the call charges when it is used for private use. ..

In addition, as an application example of the present invention, for example, for a mobile station apparatus having an answering machine function, an answering machine answering telephone number designation mode is set, and in the mode, the above operation is performed according to a key operation on a keypad. After selecting and registering one of the telephone numbers, it is possible to add a function for always operating to answer the incoming call in the answering machine when the registered specific telephone number is called.
