Information is transmitted and received between the Mobile Station (hereinafter abbreviated as MS) and the CS using radio waves. In this case, information is transmitted and received with the C8 in the area where the car is currently located, but information is transmitted and received with the MS for each CS in each adjacent area.
I'm trying to change the reception channel.

By the way, the telephone charges for conventional car telephones are MT.
It was only known through SO, and the MS side, that is, the car phone user, could not directly know the telephone usage charges.

D. Problems to be Solved by the Invention However, if the user cannot directly know the telephone usage charges as described above, troubles regarding charges may occur. In particular, when installing car phones in taxis, etc., the possibility of problems with charges is a major drawback, and is a major reason why the installation of car phones in taxis is not widespread. There is.

This invention improves this drawback by making it possible to display telephone usage charges, that is, billing charges, on the MS side.

E Means for Solving the Problems The mobile station radiotelephone device of the present invention has a mobile station MS (
Data DA indicating that the mobile station MS is equipped with a charge display system when transmitting information for establishing a wireless telephone line between the mobile station MS (10) and the fixed station C3 (2) to the fixed station CS (2). means (22) for transmitting the data DA;
After sending the charging rate information C from the fixed station CS (2)

It is provided with a calculating means (30) for calculating charges according to RD, and a display means (32) for displaying the calculation results of this calculating means (30).

F Working mobile station radio telephone M S (10) and fixed station C3 (2
) When the mobile station transmits information for establishing a wireless telephone line with the fixed station by the means (22), it also transmits data DA indicating that the mobile station has an accounting display function. The fixed station CS (2) receives this data DA and sends charging rate information CRD back to the mobile station M S (10). When the mobile station MS (10) receives this charging rate information CRD, it becomes possible to make an actual call and starts calculating the charging (telephone usage fee), and calculates the fee according to the charging rate information according to the call time. It is done.

The fee is then displayed on the display means (32). In this case, the charge may be displayed only after the call ends, but it is also possible to display the charge up to that point moment by moment during the call.

G Embodiment G, Description of a Car Telephone System FIG. 2 is an example of an outline of a system in which the present invention is applied to a cellular one-way car phone.

That is, in the same figure, (1) is a normal wired telephone line, MTSO connected to L2, and (2) is C connected to this MTSO (1) by cable (3).
8, and C8 is equipped with a transmitting and receiving antenna (2A). (
The MS is equipped with a transmitting and receiving antenna (IOA). M S (10) also includes a transmitting/receiving unit (11
), handset (12), and control unit (1
3) Be prepared. The control unit (13) is composed of a microcomputer, including a CPU (131), a program ROM (132), and a work area RAM (
133) and I10 ports (134) (135). Transmission and reception data is exchanged between the transmitting/receiving unit (11) and the control unit (13) via the I/'○ port (134).Also, via the I10 port (135) A key human power signal from the key human power section (14) is input.

In addition, (15) is the number assignment module (N
amber Assignment Module (hereinafter abbreviated as NAM), which includes your own phone number,
Data SCM (Station Class Mark (St.
-ation C1ass 14ark)) is stored. This NAM (15) is provided individually for each car phone, and the control unit (15) is provided individually for each car phone.
3) is connected to the data bus.

Reference numeral (16) denotes a display, which not only displays the telephone number of the other party at the time of the call, but also, in this example, the billing rate and billing during the call (telephone usage charge as a result of calculation).

This display (16) is connected to the data bus of the control unit (13) via a display controller (17).

A call is made between MS (10) and CS (2) by transmitting and receiving radio waves via these antennas (IOA) and (2A).
CS (2) and M S (10) by control channel
After the wireless circuit connection between the devices is established, this call can be made on the voice channel. Note that in the case of a cellular system, as mentioned above, the channel frequency is different in C8 in the adjacent area, and the MS (10) tunes to the strongest one among the radio waves from multiple CSs (2). By doing so, C S (2) is selected that covers the area including the current device of M S (10).

In this case, the channels are upstream (MS→C5) and downstream (C5).
3-MS), there may be a control channel and a voice channel, or the control channel and voice channel may be integrated to create a total of two channels, one upstream channel and one downlink channel, or the control channel and voice channel may be separated. In this case, there may be a total of 4 channels, 2 upstream channels and 2 downstream channels, and the channel design is arbitrary.

In this invention, when a voice channel is established using a control channel, M is transferred from M S (10) to CS (2).
Data DA indicating that S (10) is a mobile station equipped with an accounting display system is sent.

As this data DA, as a first example, ViS6 (
JO) NAM<15>(D+"-95CM (41:"
A part (1 bit) of 7)) can be used.

As a second example, a method can be used in which serial numbers specific to car phones are assigned separately depending on whether or not they are equipped with a billing display system, and this is determined by MTSO. This serial number is MS (1
It is always sent from MS (10) to CS (2) at the initial point of channel establishment between CS (2) and CS (10).

The third example is effective when billing is done only when making a call from MS (10). When there is a key with a special number, data DA can be converted to CS.
(2). That is, in the case of a taxi car phone, for example, the data DA can be changed by manually inputting the box [[[[[] before entering the destination phone number.
is sent to CS (2).

CS (2) sends this data DA to MTSO (1). MTSO (1) determines the contents of this data DA and
When it is determined that S is equipped with a charge display system, the charge rate is calculated and the calculated charge rate data CRD is sent to C3(2).

CS (2) transfers this billing rate data CHD to MS (
10).

The MS (10) displays this billing rate data CRD on the display (16), and after establishing a substantial communication channel with the other party, calculates the telephone charge based on this billing rate. The results are sequentially displayed on the display (16) during the call. and,
When the on-hook or end key is pressed to end the call, calculation of the telephone charge stops and the telephone charge up to that point is displayed on the display (16).

G. Explanation of Processing on the Car Phone Side FIG. 3 is an example of a flowchart of the processing in MS (10) when a call is made from MS (10) (referred to as origination time).

That is, when there is key human power, it is determined whether or not it is a predetermined key human power (step [101]), and if it is another key human power, processing is performed according to the key human power (step (102)). )), if the predetermined key is used, send data DA indicating that the phone is equipped with a billing system to the CS (2) along with an origination message that includes the serial number of the own phone and the other party's phone number. (Step (103)). If the data DA transmission method is the second example described above, this data DA is a serial number.

If the data DA transmission method is the first example or the second example, the predetermined key power is the key power of the destination telephone number and the SEND key power, and in the case of the third example. In addition to this, there is a special key manual in front of the feed key,
For example, the key input is IH[[1.

CS (2) receives the origination message and data DA from MS (10).
), the MS (10) receives this initial voice channel message (step [104]).

Up to this point, communication between MS (10) and CS (2) has been through the control channel.

When the MS (10) receives the initial voice channel message, it tunes to the designated voice channel (step (105)).

This tuned voice channel has CS (
5AT (Supe) to check the other party's MS from 2).
A sine wave signal called rvisory Audio Tone) is being sent, and M S (10) uses this SA
Upon receiving T (step (106)), M S (1
0) to CS (
Send a return message to 2) (step (107))
.

After the CS (2) confirms the other party through this SAT exchange, the CS (2) confirms the originator received from the MS (10).
Data DA with John Message MTSO (1)
send to The MTSO (1) sends a dialing signal for calling the other party from the origination message to the wired telephone line. Then, the destination exchange outputs a tone that calls the other party, and this is transmitted to MTSO (1), CS (
2), so MS (10) receives this tone (step (108E)).

When the other party goes off-hook in response to a call, M
TSO(1) detects this and stops the ring tone. Then, send the response message to the other party by CS (2
), and also determines whether the MS (10) is equipped with a charge display system based on the data DA sent from the MS (10), and if it is equipped with a charge display system, the charge rate data CRD is sent to 08 (2). send to C3(2) sends this destination response message and charging rate data CHD to M.
S (10). If the other party does not answer the call, these data will not be sent to the MS (10).

Therefore, the MS (10) determines whether or not this destination response message and charging rate data CRD have been received (step (109)). If these data are not received, the MS (10) waits for the end key input or on-hook (step (109)). Step [110]): Release the communication line; Step [116)): 14 is completed.

On the other hand, when these data are received, start calculation of telephone charges based on the charging rate data CRD (step 111)), display the charging rate and charge calculation results on the display (16) (step 112), The mode becomes conversation mode with the other party (step [113]).

Then, until the end key or on-hook,
Steps (112) (113) continue until the end key or on-hook is reached (step (114))
, step (115) to stop telephone charge calculation
), the step (116)') of sending a signal for line release to C5(2) is completed.

C S (2
) sends a release message to 173 mouth (1) and MT
SO(1) releases the line and sends a message back to C3(2) indicating the release. With that, M.S.
The sequence at the time of transmission from (10) ends.

The example in Figure 3 is! Since the charging rate data CRD from JTSO (1) also serves as the charge calculation start signal for MS (10), this data CRD is transmitted from MTSO (1) to M via CS (2) along with the other party's response message.
Although the data CHD is sent to M S (10) in advance, the data CHD may be sent to M S (10) in advance.

That is, for example, the data DA sent from MS (10) with the origination message is 1, I
Based on this, when MS (10) determines that it has a charging system, it sends charging rate data CRD to CS (2), and MTSO (1) sends charging rate data CRD to CS (2).
S (2) also sends this data CRD when sending the initial voice channel message to M S (10). M S (10) stores this data CRD in a register, and the other party's response message is M
When sent from TSO (1), charge calculation is started based on this stored data CRD.

Note that the car phone system uses a special line, so if you want to be charged a line usage fee regardless of whether the other party answers the call or not, the data CRD sent along with this initial voice channel message will be sent along with the initial voice channel message. M
When received by S (10), this may be used as a start signal to start calculating telephone charges from this point.

Furthermore, from the perspective of line usage fees, charges may be charged not only at the time of outgoing calls, but also at the time of incoming calls (referred to as pages). In this case, when the MS (lO) receives a page message, it sends a page response message to the CS (2), but when sending this page response message, it uses data DA indicating whether or not it has a billing system.
to send. Then, when 08(2) receives this, it sends data DA to MTSO(1), and MTSO
(1) sends charging rate data CHD to CS (2), and CS (2) sends an initial voice channel message specifying a voice channel to MS (10) and also sends this charging rate data CRD. MS
(10) immediately starts charge calculation upon receiving this data CHD. Alternatively, the fee calculation may be started after the off-footer at M S (10).

It should be noted that it is more convenient for the calculation of tolls to be charged in units of currency, for example, 50 yen or 100 yen, for the charging process of the car telephone installed in the taxi. In this case, the billing rate would represent time per unit of currency. Of course, the charging rate can be freely set for each taxi company.

G. Configuration Example of a Car Telephone Figure 1 shows an example of the configuration of an MS (10), especially when the controller (13) is configured with a microcombination unit as shown in the example in Figure 2. , this controller (
The part corresponding to 13) is a functional block that represents the function executed by the microcombination unit in terms of hardware.

In the same figure, (21) is a transmitting/receiving means, through which the transmitted message or voice during conversation from the transmitted signal forming means (22) is sent to the antenna (IOA).
Various messages sent to and from the CS (2) or voices from the other party during the conversation are received via the antenna (IOA) and sent to the received signal processing means (23). The received signal is provided.

(24) is a transmitter, and the outgoing voice during conversation is sent from this transmitter (24) to the transmission signal forming means (22).

Further, (25) is a telephone receiver, and the voice from the other party is supplied to this telephone receiver (25) via the received signal processing means (23).

(26) is a NAM, which supplies specific data about M S (10) to the control means (20).

Further, when using an SCM as the data DA, the SCM is read out in accordance with a control signal from the control means (20) and supplied to the transmission signal forming means (22). Further, at the time of page, information for matching the car phone number of the page message with the own car phone number and other information is supplied from this NAM (26) to the received signal processing means (23).

(27) is a key manual means, and when a key manual operation is performed,
A decode output corresponding to the operated key is obtained from the key decoding means (28), and this is output to the control means (28).
0) and also to the transmission signal forming means (22).

The transmission signal forming means (22) has a register for the serial number of its own telephone, a SAT generation section, and other transmission message generation sections, and as described above, includes the serial number and the destination telephone number at the time of origination. It sends an origination message, and sends a page response message during paging. When sending these messages, the MS (10) sends data DA indicating whether or not it is equipped with a billing system.

When using the SCM of NAM (26) as data DA, read this SCM from NAM (26). Further, when forming data DA using a special key manual, for example [EE][1, as described above, for example, prior to manually inputting the destination telephone number, the key manual means (27)
Do this key human power.

At the time of page, the received signal processing means (23) receives the Bayge message from C3 (2) via the transmitting/receiving means (21).
Receive the phone number and NAM (26) on the page message
It compares its own telephone number from , and if it matches, it sends a signal indicating this to the control means (20). In response to this, the control means (20) transmits a signal to the transmission signal forming means (20).
1) is supplied with a control signal that causes it to send a page response message.

After sending the origination message or the page response message, the initial voice channel message sent from the CS (2) is interpreted by the received signal processing means (23), and the result is supplied to the control means (20). be done. Control means (20
) receives this and supplies a tuning signal for tuning the designated voice channel to the transmitting/receiving means (21).

And after the voice channel is tuned,
From this transmission signal forming means (22), CS (2) and M
S (10) sends a SAT for mutual confirmation. During a conversation, the voice from the transmitter (24) is supplied to the transmitting/receiving means (21) via the transmitting signal forming means (22), and is sent to C3 (2) through the voice channel,
The signal is sent to the other party via the TSO (1), while the signal from the other party is sent to the MS via the MTSO (1) and C3 (2).
(10), the MS (10) sends this voice to the receiver (25) via the transmitting/receiving means (21) and the received signal processing means (23), and reproduces it through its speaker.

Next, billing will be explained.

That is, the charging rate data CRD received by the transmitting/receiving means (21) is supplied to the control means (20) and is also supplied to the charging rate register (29) and stored therein. . Data CHD from this register (29) is then supplied to charging calculation means (30). When the charging rate data CHD is sent together with the destination response message from C3(2), the controller (
20), an accounting start signal ST is obtained immediately upon receiving this data CRD, and this start signal ST is supplied to an accounting calculation means (30). Charge calculation means (30
) is provided with a time measuring means, and the start signal S
Time measurement is started by T, and the calculation of telephone charges based on the data CRD is started.

When the data CRD is sent from the C3 (2) together with the initial voice channel message, the control means (20) detects the arrival of a signal indicating that the destination response message has been received from the reception signal processing means (23). After waiting (or waiting for off-hook when paged), it outputs a start signal ST.

The calculation result of the charging calculation means (30) is supplied to the display (32) via the selector (31) and displayed.

At this time, information on the billing rate and usage time is also calculated by the calculation means (
30) to the display (32), and the billing rate and usage time are displayed at the same time.

The selector (31) is used to switch the display (32) between a telephone number input display and a charge display. The selector signal SEL at (31) sets the mode for manual display of telephone numbers, and the telephone number input from the key decoding means (28) is supplied to the telephone number display signal generation means (33), which generates a telephone number (
A telephone number display signal from 33) is supplied to the display (32) via the selector (31), and the input telephone number is displayed.

The selection signal SEL from the control means (20) is the billing start signal S from the control means (20).
When T is sent out, the charging display mode is set and the selector (31) selects information from the calculation means (30).

Normally, car phones take into account the possibility of entering a wrong phone number.
When the clear key is pressed manually, the telephone number display on the display is erased, and the old display is rewritten with a new number type key. However, when a car phone with a charging display system is installed in a taxi or the like, if the charging display is easily erased by the user after the user has used the phone, the user will not be able to tell the charge and this will cause trouble. , Therefore, in this example, this problem is solved as follows.

That is, the output of the key decoding means (28) is supplied to the clear signal generating means (34), and the key decoding means (27)
When the clear key is pressed manually, a clear signal is obtained from this, and this clear signal is supplied to the telephone number display signal generating means (33) and also to the clear switching means (35).
is supplied to one input end of the .

On the other hand, (36) is a specific code generation means, from which the same output as the key decoding means (28) is obtained when a specific 3-4 digit key is inputted using the key manual means (27).
This is supplied to the coincidence detection means (37).

Further, the output of the key decoding means (28) is supplied to the coincidence detecting means (37). Therefore, when the specified three to four digit keys are pressed by the key manual means (27), the two manual powers of the coincidence detecting means (37) match, and at this time, a clear signal is obtained from this means (37). This clear signal is then supplied to the clear switching means (35).

The clear switching means (35) is supplied with a select signal SEL from the control means (20), and in the telephone number display mode, the clear switching means (35) is supplied with a clear signal SEL supplied to one input terminal. Generating means (34)
When in charge display mode, the clear signal from the match detection means (37) is selected.

Therefore, in the telephone number display mode, when the clear key is pressed manually using the key manual means (27), the telephone number display signal generating means (33) is cleared and the telephone number display on the display (32) is erased, and a new The old display will be overwritten by entering the number.

In addition, when in charge display mode, key manual means (27)
Even if the clear key is pressed manually, the charge display on the display (32) will not be erased. Then, the charge display on the display (32) is erased only when a specific three to four digit key is pressed. Therefore, if only the taxi driver knows this specific 3-4 digit key input and does not let the car phone user know, there will be an inconvenience that the billing display will be erased by the user. can be avoided.

Furthermore, in this example, even if the billing display is cleared in the manner described above, consideration has been given to making it possible to display it again by a special key operation such as a dual-key manual operation of a function key and a specific number key, for example. .

That is, (38) is a memory backed up by a battery (39), and the billing rate from the billing calculation means (30),
Information on usage time and calculation results is stored in memory control means (
40) is written by the write signal from 40). This writing may be done only when the call ends due to an end key or on-hook, or it may be rewritten each time the display content is updated every time per charging unit, and after an end key or on-hook, You may choose not to write it.

A read request signal from the read request means (41) is sent to the memory control means (40).1. :
When supplied, the billing rate, usage time, and fee are read out from the memory (38) by the readout signal from the control means (40), and displayed on the display (
32) and display it.

In this case, the read request means (41) generates a read request signal in the following cases.

That is, (42) is a read request determination means, and when the above-mentioned special key operation is performed by the key manual means (27), the output of the key decoding means (28) is outputted to this determination means (4).
By determining 2), it is determined that the special key operation has been performed, and the determination output is used as an or game) (43)
is supplied to this read request means (41) via.

Upon receiving this determination output, the requesting means (41) issues a read request. Therefore, the charge display that has been cleared once can be displayed again on the display (32) by operating this special key.

Also, the signal P obtained when the power switch is turned on
. , is supplied to the read request means (41) via (43), and a read request is also issued when the power is turned on. Therefore, when the power is turned on, the previous charge display is displayed on the display (32). As a result, even if the power is turned off and the billing display disappears, by turning the power back on again, the billing display that was just before the power was turned off can be redisplayed on the display (32).

Mainly, when charging in units of currency as described above, it is also possible to notify the user by emitting a beeping sound, for example, 10 seconds before the charge increases.

(44) is a speaker for that purpose, and billing calculation means (30
), the alarm sound signal is formed based on the time measured by the time measuring means, and is transmitted to this speaker (4).
4). This speaker may also be used as a telephone receiver.

It is also possible to store the billing information in the memo IJ (38) and manually calculate and display the previous charge, the total charge for the current day, and the total charge for one month.

The above is an example in which the present invention is applied to a car phone in a cellular one-way car phone system, but this invention is not limited to a cellular one-way system, and the mobile station can be used in applications other than automobiles. It can be applied to various types of moving objects.

Effects of the Invention H As described above, according to the present invention, charges can be calculated and displayed on the mobile station side, so troubles regarding charges can be prevented when the mobile station is installed as a car phone in a taxi, for example. We can expect the spread of mobile phones, etc. to increase.
