FIG. 8 is a diagram showing a connection control procedure of the automobile telephone device 200.

When the power of the automobile telephone device is turned on, a reset operation starts (step 801). The operation at that time will be described with reference to FIG. First, when the power is turned on, C
Each part is reset by the PU 331 (step 85
0), it is confirmed whether the device is in a usable state.
This confirmation is defined as a lock state confirmation (step 852). No one else is allowed to use the device unless the lock is released. In the locked state, “LOOK” is displayed on the display unit 450 (step 854). On the other hand, if the locked state is not set, "NO SVC" is displayed (step 85).
6). “NO SVC” means that the communication service is not started during the reset operation. When the reset operation is completed, the process proceeds to initialization (step 802).

FIG. 10 is a detailed flowchart showing the initialization after the power is turned on. Audio / control unit 3
The wireless unit control unit 336 in the control unit 30 controls the synthesizer 320 to convert an output into a frequency according to a control signal from the CPU 331. By this control, a predetermined range of a control channel (hereinafter, referred to as a D channel) is set to the demodulator 31 in order to obtain field strength information of a received signal on each channel.
2 is scanned (step 901). Then, the channel having the strongest electric field strength is selected from the D channel,
The device is in a state of receiving a D-channel signal having the strongest electric field strength. At this time, channel information having the next highest electric field strength among the D channels is also obtained.

Further, the audio circuit control unit 339
Under the control of the PU 331, the audio circuit 33 outputs the demodulator 312 so that the output of the demodulator 312 becomes the input of the control signal processing unit 338 and the output of the control signal processing unit 338 becomes the input of the modulator 314.
7 is controlled.

The control signal processor 338 synchronizes the received signal from the selected D channel with the bit synchronization and the frame synchronization, that is, the word synchronization (step 903), whereby the communication link is set between the mobile phone and the base station. . At this time, the system information is extracted from the received signal of the D channel by the control signal processing unit 338 (step 905) and sent to the CPU 331. The system information includes a system identification number (hereinafter, S) to be scanned next.
ID) and a range of frequency channels (hereinafter, referred to as a P channel). The reception SID indicates a mobile telephone switching station that covers an area where the car telephone is located. Then, the CPU 331 stores the SID in the SID register of the RAM 335.

If word synchronization or system information reception is not performed within a predetermined time, the same operation is performed by the D channel having the next highest electric field strength (step 907). In this case as well, if word synchronization or system information reception cannot be performed within a predetermined time, the demodulator will scan the D channel again (step 9).
01).

When the initialization is completed, a similar scan is performed to receive the input signal of the P channel (step 803 in FIG. 8).

FIG. 11 is a detailed flowchart showing the operation of the P channel after initialization.

In response to a control signal from the CPU 331,
Since the P channel is scanned using the demodulator 312 so as to obtain the electric field strength information of the received signal, the radio unit control unit 33
In step 6, the synthesizer 320 that converts the output into a frequency is controlled (step 1001). The device waits for a reception signal from the P channel having the strongest electric field strength,
Information on the P channel having the next highest electric field strength among the channels is also obtained.

Then, the control signal processing section 338 establishes bit synchronization and frame synchronization, that is, word synchronization with the P channel receiving the strongest electric field strength (step 100).
3) After the synchronization is completed, the control signal processing unit 338 obtains system information including an SID indicating a mobile telephone switching station which services the mobile telephone from the information signal (step 10).
05), and sends it to the CPU 331. If word synchronization or system information reception is not performed within a predetermined time, the same operation is performed using the P channel having the next highest electric field strength (step 1007). Also in this case, if word synchronization or system information reception is not performed within a predetermined time,
Initialization is performed again (step 80 in FIG. 8).
2). After the end of the above control, the apparatus enters a reception standby state (step 804 in FIG. 8).

Now, if the apparatus obtains an input signal in the reception standby state in step 804 in FIG.
Shift to the input sequence shown in FIG.
5). First, the CPU 331 detects an incoming call signal including the MID from the P channel (step 1101). here,
The incoming call mode flag is checked (step 110).
3) If the incoming call mode flag is "1", the received MID
Is compared with the MID stored in NAM1 (step 11).
05). If the received MID matches one of the MIDs stored in NAM1, CPU 331 causes the demodulation unit to scan each predetermined control channel (defined as A channel) in order to obtain the strongest field strength information (step 110).
9). In this case, the next strongest electric field strength information is also obtained. If the received MID does not match any of the MIDs stored in NAM1, initialization is performed again (FIG. 8).
Middle step 802). On the other hand, the incoming call mode flag is "0"
In the case of (1), the received MID is compared with the MID stored in the IDROM (step 1107). Received MID is IDRO
If it matches one of the MIDs stored in M, the A channel is scanned (step 1109). If it does not match any of the MIDs stored in the IDROM, initialization is performed again (step 802).

Next, word synchronization is performed with the received signal from the selected A channel (step 1111). If the word synchronization is performed within a predetermined time, the system information is detected from the reception information of the A channel (step 111).
3) If word synchronization is not performed or system information is not obtained within a predetermined time, A having the next highest electric field strength
Similar processing is performed on the channel (step 11).
15). At this time, similarly, if word synchronization cannot be obtained or system information cannot be obtained within a predetermined time, initialization is performed again (step 802 in FIG. 8).

After the system information is obtained, a reception notification signal is transmitted to the base station using the A channel (step 1117). The reception notification signal includes the corresponding MID and serial number. When the base station receives the reception notification number, the base station compares the MID and serial number with the registered MID and serial number as shown in FIG. If they match each other and the MID corresponds to the serial number, the base station sends out the designated channel information.

If the device receives the signal within a predetermined time (step 1119), the A channel includes a front channel for transmitting the voice signal to the base station and a rear channel for receiving the voice signal from the device. The call channel is switched (step 1121). Thus, a communication link between the called telephone device and the calling telephone device is set up. If the MID and serial number do not match the registered MID and serial number in the base station,
If does not correspond to the registered serial number, the base station does not transmit a signal including the designated communication channel information. Also,
If the CPU 331 does not detect a signal within a predetermined time (step 1119), initialization is performed again (step 802 in FIG. 8).

Thereafter, the apparatus enters a standby state until an incoming call signal is received (step 806 in FIG. 8). Upon receiving the incoming call signal, the apparatus generates a ringing tone and waits for a response from the user (step 809). ).

When the user depresses the "transmit" key and answers the ringing tone, handset control section 418 detects the key operation and sends a control signal corresponding to the "transmit" key operation to line 5.
02 via digital interface 340 on CP
It transmits to U331. Also, when the user sets the handset 40
If 0b is off-hook, information indicating the hook switch state of the switch 470 is transmitted to the CPU 331 via the digital interface 340 on the line 501. The CPU 331 transmits a connection signal to the audio circuit control unit 339 according to the off-hook control signal and the control information. When the audio circuit control unit 339 receives the connection signal, the audio circuit control unit 339 controls the audio circuit 337 using the line 503 so that the demodulator 312 and the modulator 314 are connected to one of the audio input / output units 490a and 490b. In this way, the user can use the hands-free microphone 49.
4 and the speaker 492 or the handset microphone 466 and the handset receiver 498 to communicate with the caller. Notification signal transmission state (step 111
7) Each notification signal in the communication channel reception state (step 1119), the communication enabled state (step 1121), or the user's response waiting state (step 809 in FIG. 8) is lowered for a predetermined time, and the electric field strength of the communication channel becomes predetermined. If the level cannot be maintained, transmission becomes impossible.

Also, if the user goes on-hook on the handset during the communication, the communication via the communication channel is stopped (step 807), and transmission becomes impossible (step 8).
08), initialization is performed again (step 80).
2).

Next, the flow of the calling process will be described with reference to the flowcharts shown in FIGS.

First, when a call request is input from the key unit 430 during the standby waiting state shown in step 804 in FIG. 8, a timer for counting the call reception time is set (step 1201). The time is, for example, 12 seconds.

Thereafter, in order to obtain the electric field strength information, the radio unit control unit 336 in the radio unit 300 causes the demodulator 312 to scan a predetermined control channel (step 120).
2). Then, the A channel having the strongest electric field strength is selected from these control channels, and the apparatus enters a receiving state for the channel. At this time, information on the A channel having the next highest electric field strength among the A channels is also obtained.

Next, it is confirmed whether or not the user intends to make a call (step 1203). The confirmation procedure is described below. When the user inputs a telephone number from the key section 430 and presses down the “transmit” key, the handset control section 418 detects the key input and transmits a detection signal to the CPU 331 in the audio / control section 330. When the call flag of the CPU 331 is set to “1” by the detection signal, the apparatus recognizes that the user has the intention to call. However, if the "end" key is depressed after the "send" key is depressed, the call flag is reset to "0". In this case, the device recognizes that the user has no intention to make a call, and initialization is performed again (step 80 in FIG. 8).
2).

Thereafter, the control signal processing section 338 performs bit synchronization and frame synchronization, that is, word synchronization with the reception control channel, and obtains system information from this control channel. If word synchronization cannot be achieved, the same operation is performed by the control channel having the next highest electric field strength (step 1205). Also in this case, if word synchronization is not achieved, initialization is performed again (step 802 in FIG. 8).

At this point, it is again confirmed whether or not the user intends to make a call (step 1206). As in the case described above, if the call flag is "1", the apparatus recognizes that the user has the intention to make a call, and if the call flag is "0", the apparatus recognizes that the user does not intend to make the call, and the apparatus initializes again. (Step 802 in FIG. 8).

The CPU 331 analyzes the system signal information from the base station and checks whether the selected control channel is appropriate. If an appropriate control channel has been selected (step 1207), the channel selection flag of the CPU 331 is changed from "0" to "1". If not, initialization is performed again without changing the channel selection flag (step 1207). Step 802 in FIG. 8). If the selection of an appropriate control channel is delayed (step 1208), the intention to call is confirmed again (step 1206).

In FIG. 14, the calling mode flag is set to "
If “1” (step 1210), the MI in NAM2
It is checked whether or not there is D, and if there is an MID, the MID in NAM2 is adopted (step 1213).

If the calling mode flag is "0" (step 1210), the user is notified of the MID in the ID ROM 370.
In order to select one of 1-3, "Please enter the MID for calling." 1 "-MID1," 2 "-MID
2 "," 3 "-MID3" (step 121)
4). When a key operation corresponding to one of the MIDs is performed, the CPU 331 determines whether a MI operation in the ID ROM corresponding to the key operation has been performed.
D is adopted (step 1216), and if there is no key operation, an MID in the IDROM 370 having a predetermined priority flag is adopted (step 1218). As described with reference to FIG. 4, "1" is set to the MID having the priority flag in MID1, and the MID1 is adopted. When there is no MID in NAM2 (step 12
12) Then, initialization is performed again (step 802 in FIG. 8).

After the adoption of the MID, a call signal including the adopted MID, serial number and device identification number is sent from the control channel (step 1220). When the base station receives the notification signal, the reception MID and the serial number and the registration M
The ID and the serial number are compared, and if they match each other, the base station transmits a notification signal to the device. Thereafter, the mobile telephone device detects whether or not a notification signal has been received from the base station (step 1222). The base station calls the other station using the identification number included in the call signal. Then, a communication link is set between the car telephone device and the called telephone device (step 1224). If the setting cannot be made, initialization is performed again (step 80 in FIG. 8).
2).

As described above, the communication link can be set (step 810 in FIG. 8), and thereafter, the communication ends.

At this time, the key input in step 1216 can be replaced by voice, and the replaced voice is detected by the voice synthesizer shown in FIG. When displaying the information of the selected MID to the user, the voice synthesizer shown in FIG. 3 generates a voice corresponding to the information.

Also, as described in the incoming call receiving procedure, if the received MID matches one of the MIDs stored in NAM1, a procedure for setting a communication link and receiving a predetermined incoming call is used. For example, it becomes possible for the user to use the device for public use on weekdays and for private use on holidays.

Further, as described in the call processing procedure, N
When the MID is stored in the AM2, the communication link is set up using the MID, so that the user can pay the user fee while distinguishing between the user fee for public use and the user fee for private use. become.

Next, another specific example will be described with reference to the block diagram of FIG. The audio circuit 337 is connected to the microphones 494 and 466 and the switch 391, and the switch 391 is connected to the speakers 492 and 498 and the facsimile 39.
3 is connected. Although not shown, the facsimile 393 has a CPU, a memory, a detection unit for detecting a ringing tone, and a storage unit. The switch 391 is controlled by the control signal processing unit 338.

FIG. 16 shows the contents of NAM1 in this example. Two MIDs 1 and 2 each have a predetermined address FF0
0, FF01 and the serial number SER. 100 is stored. Also, a telephone identification number is assigned to MID1 and MI
A facsimile identification number is stored in D2 and M
The flag corresponding to ID1 is “0”, and the flag corresponding to MID2 is “1”.

FIG. 17 shows the relationship between the received facsimile signal and M
It is a flowchart which shows the process which stores at least 1 of ID1-3. When the user wants to select one MID for receiving a facsimile signal, for example, "FC
It is checked whether the key operation of N ","#"," 6 "," 0 "has been performed (step 1301) .If a key input has been made, a beep sound is generated (step 1303).
The MID stored in AM1 is displayed (Step 130)
5). Then, in order to allow the user to select the MID, "Enter the facsimile MID." 1 "-MI
D1, "2" -MID2, "3" -MID3 "are displayed (step 1307). Here, if "1" is input by a key, MID1 is stored in NAM1 (step 130).
9, step 1311), if "2" is keyed in, M
ID2 is stored in NAM1 (step 1313, step 1315), and if "3" is entered by key, MID3 is set to N
AM1 (Step 1317, Step 131)
9). If none of the operations “1”, “2”, and “3” is performed, no MID is stored in NAM1. A certain MID
Is stored in the NAM1, the flag of the storage MID is set to "1" with respect to the reception of the facsimile signal (step 132).
0), the flag is set to "0" for an incoming telephone call. In the example of FIG. 16, MID2 is a facsimile signal receiving MID, a flag is set to "1", MID1 is an MID for receiving a telephone call, and "0" is set to the MID1 flag.

FIG. 18 and FIG. 19 are flowcharts showing the receiving process of the facsimile signal. First, the device receives an incoming call signal (step 1501), and the reception MID is NA.
If none of the values in M1 match, initialization is performed (step 802 in FIG. 9). Receive MID is NAM
1 matches one of the MIDs (step 150).
3), check the flag of NAM1 (step 150)
5). If the flag corresponding to the MID in NAM1 is "1", the control signal processing unit applies the control signal to the switch 391, and the audio circuit 337 is connected to the facsimile (step 1507). If not “1”, the control signal processing unit does not supply the switch 391 with a control signal.

Thereafter, step 1109 in FIG.
From step 1 in the same manner as the processing shown in step 1121.
From step 509, step 1521 is performed.

In the standby state (step 152)
3) If the received MID matches the MID specified as a telephone (step 1524), step 809 shown in FIG.
The processing is performed from. If the received MID matches the MID specified for facsimile, a call signal is detected (step 1525), and generally known facsimile processing is performed. As described above, it is possible to specify the MID for the facsimile number and the telephone number.

Further, in this example, the control signal processing unit receives the reception MI signal.
It is determined whether or not D matches a numerical value for facsimile or telephone, and based on the result, the audio circuit 337 and the facsimile 393 are connected. However, conventional devices do not have this characteristic, so when receiving a facsimile input after off-hook of the handset, it is necessary to manually switch the audio circuit to facsimile if the facsimile transmission sound is heard .

In FIG. 15, the facsimile apparatus can be another terminal apparatus. In this example, an example of application to a car telephone device is shown, but it is clear that the present invention is applicable to any wireless communication device such as a mobile phone.

The present invention is also applicable to a dual mode device such as a digital modulation system or an analog modulation system, and the concept of the present invention is also applicable to a data transmission device using a cellular wireless communication system. You can.
