line 1005 extending from power source 390 in radio unit 300. The opened or closed status of switches 470 is transmitted to power source 390 or radio unit controller 330 by way of line 1000 or line 1001, respectively.
Control and/or command signals are transmitted between handset controller 418 and radio unit controller 330 by way of line 1002. Audio signals are transmitted by way of lines 1003. Radio unit controller 330 sends control signals to audio input/output unit 490a, 490b by way of lines 1004.
Fig. 2 is a block diagram showing a detailed arrangement of the radio unit of Fig. 1. Referring to Fig. 2, radio section 310 comprises demodulator 312, modulator 314, duplexer 318 and synthesizer 320.
Demodulator 312 demodulates a radio signal received from the base station through radio channels 600, antenna 200 and duplexer 318. It should be noted that this signal includes audible sound signals and control signals. Modulator 314 modulates the audio and control signals received from audio controller 300 and generates the requlred transmi~sion slgnals.
Power ampllfler 316 ampllfles the transmlssion slgnals received from modulator 314. The ampllfication of power ampllfler 316 may be continuous or variable in a step-wlse fashlon, e.g., 8-step varlable. Duplexer 318 sends the signals received through radio channel 600 to demodulator 312 and the signals from modulator 314 , .

and power amplifier 316 to antenna 200. Synthesizer 320 is formed of a channel selection local oscillator and specifies a frequency from which signals are demodulated by demodulator 312 and a frequency to which signals are modulated by modulator 314.
Radio unit controller 330 is formed at central processing unit (CPU) 331, oscillator/frequency divider 332, address decoder 333, ROM 334, RAM 335, radio controller 336, audio circuit 337, control slgnal processor 338, audio circuit controller 339, digital interface 340, power controller 341 and interrupt controller 342. Reference numerals 343, 344 and 345 denote a data bus, an address bus and a control bus, respectively. CPU 331 controls the operatlon of radio unlt controller 330. Osclllator/frequency dlvider 332 supplles clock slgnals to CPU 331 and dlvldes the clock slgnals to supply approprlate frequency-dlvlded pulses as tlmlng pulses to each sectlon of the moblle telephone apparatus requlrlng them. Address decoder 333 outputs predetermlned operation slgnals to the components ln response to instruction slgnals from CPU 331. ROM 334 stores varlous programs requlred for operation of CPU
331. RAM 335 stores varlous types of data durlng processing for use by CPU 331. Radio controller 336 controls radio section 310 in response to lnstructions from CPU 331. For example, radlo controller 336 sends signals lndlcatlve of avallable frequencles to ;
2 ~ 2 ~
synthesizer 320, sl gnals indicative of an amplificatlon level to power amplifier 316, and signals indicative of modulation parameters to modulator 314. Radio controller 336 receives a step-out signal from synthe-sizer 320 and output power detection signals from poweramplifier 316 and forwards these signals to CPU 331, thereby preventing operational errors.
Audio circuit 337 extracts control signals and audio signals from the received signals demodulated by demodulator 312 and supplies the control signals to control signal processor 338 and the audio signals to telephone unit 400. Audio circuit 337 also supplies a control signal from control signal processor 338 and audio signals from telephone set 400 to modulator 314.
It should be noted that audio circult 337 also arranges the waveform of the control signal to be sent to control slgnal processor 338 in a particular slgnal format and filters the control signal to be supplied to modulator 314. Control signal processor 338 acquires bit and frame synchronization with the control signal from audio circult 337. Malntainlng the requlred synchronlzation, control signal processor 338 converts the serial control slgnals, lncludlng control data recelved from a base statlon, lnto parallel slgnals and converts the parallel control data slgnals to be transmltted to a base station lnto serlal signals. The control signals are set to and from the base statlon vla audlo clrcuit 337.
202~2i'3 Audio circuit controller 339 controls audio circuit 337. Under the control of audio circuit controller 339, for example, audio circuit 337 applies the received signals from demodulator 312 to control signal processor 338 or telephone unit 400 and selectively receives the signals from control signal processor 338 or telephone unit 400. Digital interface 340 interfaces the data communication between radio unit 300 and telephone unit 400. Power controller 341 controls power source 390 and sets a voltage supplied from battery 506 to power source 390 to a predetermined level. The voltage having the predetermined level is supplied to the respective clrcult components.
An operation of the radlo telecommunlcatlon appa-ratus havlng the above-described arrangement accordlng to the flrst embodlment of the present lnventlon wlll be descrlbed below.
Prlor to speech communlcatlon processing in the apparatus of thls embodlment, the apparatus may be swltched from a standby state to an allowable call charge reglstratlon mode by a predetermlned key opera-tlons, e.g., depresslng keys oflFCN 1, ~ , ~ , continuously. After that, an allowable call charge may be reglstered into the apparatus by operatlng ten-keys.
For example, keys of m ~ ln the key sectlon 430 are operated to enter $10 as the allowable call charge, and thls lnput value ls stored ln the ID ROM 370 . ........ . . .
, ~' ' ' , 2~ ,3 constituted by an E2PROM.
The flow of operation shifts to an outgoing call operation in response to the input of a destination telephone number and the send key. Upon this outgoing call operation, over a control channel established between the apparatus and the base station, system data is received from the base station. Information repre-sentative of a charge rate is then extracted from this system data and is stored in the RAM 335.
The base station designates a speech channel for the mobile unit. In accordance with this designation, the mobile unit is tuned to the speech channel, and the base statlon ls also tuned to the speech channel.
Speech communication ls then started through the deslgnated speech channel.
In synchronlsm wlth an establishment of a speech communlcation llnk, the CPU 331 starts to count a speech communlcatlon tlme by uslng an lnternal clock pulse, and sequentlally calculates call charges on the basis of the charge rate stored in the RAM 335 and the count values. The CPU 331 fetches the allowable call charge data from the ROM 370 and compares it with the calcula-tlon results. If it is determined that a call charge exceeds the allowable call charge, the CPU 331 sends a control slgnal for generatlng an alarm slgnal to the audio clrcuit 337. The audlo clrcult 337 sends the alarm slgnal to the loudspeaker 492 or the handset 292~52s5 receiver 498 so as to cause the loudspeaker 492 or the handset receiver 498 to generate an alarm.
The user can confirm from this alarm that the current call charge exceeds the allowable call charge.
Therefore, the speech communication time can be managed in accordance with this alarm.
The above-described operation will be described in more detail below with reference to the flow chart in Fig. 3.
When it ls determined in step 30 that the operatlonal state of the apparatus transits from a standby state to a speech communication state in which a speech communication link is established, the radio section 310 of the apparatus receives signals trans-mitted from the base station over the established speech communicatlon link. The received signals are applied to the control signal processor 338 through the audio clrcult 337. The control slgnal processor 338 detects a synchronization slgnal, an address data addresslng the apparatus, and the followlng system data in the received slgnals. The detected system data are applied to CPU
331 vla bus lines. The system data include lnformation concernlng a charge rate, whlch ls extracted by CPU 331.
CPU 331 stores the extracted charge rate informatlon lnto the ~AM 335 ln step 31. The charge rate infor-matlon, for example, conslsts of ten (10) blts. In step 32, the CPU 331 starts call charge count by startlng to ., . ,: , , 202~626 count a speech communication time, thus starting to calculate a call charge on the basis of the counted time and the charge rate obtained from the data received from the base station. More specifically, CPU 331 calculates a call charge by multiplexing the counted time by the charge rate. In addition, the calculated call charge may be displayed on display unit 450 under the control of CPU 331. Thus, the user may be always informed of the call charge.
In step 33, the CPU 331 compares the calculated call charge with a preset allowable call charge which was stored in the allowable call charge registration mode so as to check whether the current call charge exceeds the allowable call charge. If NO in step 33, the flow advances to step 34, and the CPU 331 calculates the next call charge corresponding to an incremented count time. After it is determined in step 35 that the speech communication link is still established, the flow returns to step 33 in which the current call charge is compared with the allowable call charge.
If the CPU 331 determines that the current call charge exceeds the preset allowable call charge, it starts, for example, the following processing in step 36:
~1) generatlng an alarm from the loudspeaker 492 or the handset recelver 498 in the mobile unit by superposing it on speech;
.
20~626 (2) transmitting an alarm signal to the destina-tion by superposing it on speech signals to be trans-mitted;
(3) displaying an alarm message on the display unit 450;
(4) causing a backlight for the display unit 450 to blink.
Note that these operations may be independently or simultaneously performed.
This lndication processing may be continued until a speech communication link using the speech channel is broken down owing to user's on-hook operations and so on (steps 37 and 38). After that, the apparatus is set in a standby state again.
According to the radio telecommunication apparatus of this embodiment, therefore, long speech communication is determined on the basis of a call charge, and this lengthy talk can be informed to the user.
In the above-mentioned embodiment, while the charge rate is obtained through the speech communication llnk after it ls established, the charge rate may be obtained in advance through a control channel before the speech communlcatlon link ls established.
The second embodlment of the present lnventlon will be descrlbed below wlth reference to the flow chart in Flg. 4.
When lt ls determlned ln ætep 20 that the apparatus : ' .
2~2~526 is set from a standby state to a speech communication state, the CPU 331 receives system data from the base station, reads a charge rate from the system data, and stores it in the RAM 335 in step 21. In step 22, the CPU 331 starts to count a speech communication time so as to start call charge count, and starts to calculate a call charge on the basis of the speech communication time and the charge rate.
In step 23, the CPU 331 compares the calculated call charge with a preset allowable call charge so as to check whether the current call charge exceeds the allowable call charge. If NO in step 23, the flow advances to step 24 to calculate the next call charge by uslng the call charge call count. When the CPU 331 determlnes that the speech communlcatlon llnk ls stlll establlshed, the flow returns to step 23 to compare the current call charge with the allowable call charge.
If the CPU 331 determines in step 23 that the current call charge exceeds the preset allowable call charge, it controls synthesizer 320 so as to supply demodulator 312 wlth signals having frequencies for scannlng the control channel and modulator 314 to be turned off. Consequently, the established speech communlcatlon llnk ls termlnated ln response to the excess of the call charge (step 26). After that, the operatlon returns to the standby state.
Accordlng to the radio telecommunlcatlon apparatus 202~2~
of this embodiment, long speech communication is deter-mined on the basis of a call charge, and the speech communication can be forcibly ended. Therefore, a good economical effect can be expected.
The third embodiment of the present invention will be described below.
Fig. 5 is a flow chart showing an operation sequence of the apparatus of the third embodiment.
In this apparatus, indlcation processing is exe-cuted when an accumulated call charge for a plurality of calls exceeds a second preset allowable call charge.
The second allowable call charge is stored in the ROM
370 by a key-operation in the same manner as in the above-descrlbed embodiments. The accumulated call charge up to the last call is also stored in the ROM
370.
When the apparatus is set from a standby state to a speech communlcation state, the CPU 331 checks in step 40 whether the accumulated call charge exceeds the second preset allowable call charge. If YES in step 40, predetermlned processing indlcatlon and communlcatlon control operatlons of, e.g., lnhlbltlng speech communl-catlon or generatlng an alarm, and lnformlng the user of thls state is performed ln the slmllar manner as descrlbed ln the above-mentloned embodlments (step 42).
If NO in step 40, the flow advances to step 41.
After outgolng call processlng, the CPU 331 recelves 202~626 system data from the base station, reads a charge rate from the system data, and stores it in the RAM 335 in step 43. In step 44, call charge count is started. A
call charge based on this count result is added to the previous accumulated call charge stored in the ROM
370, and the updated accumulated call charge is stored in the RAM 335. In step 45, the CPU 331 compares the accumulated call charge with the second allowable call charge. If the accumulated call charge exceeds the second allowable call charge, the above-described indlcation and communication control operations is performed ln step 42.
If the accumulated call charge does not exceed the second allowable call charge, call charge count is con-tlnued ln step 46. If it ls determined that the speechradlo llnk ls still establlshed ln step 47, the flow returns to step 45 to perform the same declslon proc-esslng as described above.
After the speech communlcatlon llnk ls broken down, the current accumulated call charge ls wrltten ln the ROM 370.
Note that the above~descrlbed indlcatlon and communlcatlon control operatlons can be canceled by clearlng the accumulated call charge stored ln the ROM
370.
Accordlng to the radlo telecommunlcatlon apparatus of thls embodlment, whether the accumulated call charge .,.,, .: ;

exceeds the second allowable call charge can be informed to the user.
The accumulated call charge may be stored in a detachable memory device, e.g. an IC card.
The fourth embodiment of the present invention will be described below with reference to Figs. 1, 2, and 6. In this embodiment, while the apparatus is in a standby state before speech communication, a unit time and a charge rate as call charge units are entered by the key unit 430 and are stored in the ROM 370 in step 50.
Upon operation of the key unit 430, an allowable call charge is entered as a call charge limit allowed for one call, and is stored in the RAM 335 while each input value is checked on the display unit 450.
When outgoing call processing is performed by enter-ing a destination telephone number from the key unit 430 in ~tep 51, the radio unit controller 330 performs out-going call connection processing with respect to the base station through the mobile antenna 200. Upon completion of the connection processing, the apparatus is set in a speech communication state. In this speech communication state, an audible sound signal received through the mobile antenna 200 and the radio section 310 is sent to the loudspeaker 492 through the .~
2020fi~6 audio circuit 337. The audible sound signal input from the microphone 466 is sent to the radio section 310 through the audio circuit 337.
In this radio telecommunication apparatus, count of a speech communication time is started at the same time when a speech communication state is set, and calcula-tion of a call charge is started by using the counted time and the preset charge rate in step 52. In step 53, the call charges are sequentially compared with the present allowable call charge with the lapse of a speech communicatlon time. If it is determined in step 53 that the current call charge exceeds the allowable call charge, the flow advances to step 54 to inform this state to the user. Subsequently, on-hook processing is performed (step 55), and information processing is ended ~step 56).
If the current call charge does not exceed the allowable call charge, the flow advances to step 57 to contlnue call charge count. When it ls determined in step 58 that the line is still connected, the flow returns to step 53. This processing is repeated until the current call charge exceeds the allowable call charge.
The thlrd embodiment may be comblned wlth the flrst, second, or fourth embodlment. Wlth such a combinatlon, an accumulated call charge based on a plurallty of calls can be slmultaneously managed wlth ,. . . ..

Still, any other combinations of the above-mentioned embodiments fall into the scope of the present invention. For example, the speech communication link may be terminated after the user is alarmed. In this event, a criterion for a disconnection of the speech communication link is greater than a criterion for an alarm.

line 1005 extending from power source 390 in radio unit 300. The opened or closed status of switches 470 is transmitted to power source 390 or radio unit controller 330 by way of line 1000 or line 1001, respectively.
Control and/or command signals are transmitted between handset controller 418 and radio unit controller 330 by way of line 1002. Audio signals are transmitted by way of lines 1003. Radio unit controller 330 sends control signals to audio input/output unit 490a, 490b by way of lines 1004.
Fig. 2 is a block diagram showing a detailed arrangement of the radio unit of Fig. 1. Referring to Fig. 2, radio section 310 comprises demodulator 312, modulator 314, duplexer 318 and synthesizer 320.
Demodulator 312 demodulates a radio signal received from the base station through radio channels 600, antenna 200 and duplexer 318. It should be noted that this signal includes audible sound signals and control signals. Modulator 314 modulates the audio and control signals received from audio controller 300 and generates the requlred transmi~sion slgnals.
Power ampllfler 316 ampllfles the transmlssion slgnals received from modulator 314. The ampllfication of power ampllfler 316 may be continuous or variable in a step-wlse fashlon, e.g., 8-step varlable. Duplexer 318 sends the signals received through radio channel 600 to demodulator 312 and the signals from modulator 314 , .
2~2a~ ~ ~
and power amplifier 316 to antenna 200. Synthesizer 320 is formed of a channel selection local oscillator and specifies a frequency from which signals are demodulated by demodulator 312 and a frequency to which signals are modulated by modulator 314.
Radio unit controller 330 is formed at central processing unit (CPU) 331, oscillator/frequency divider 332, address decoder 333, ROM 334, RAM 335, radio controller 336, audio circuit 337, control slgnal processor 338, audio circuit controller 339, digital interface 340, power controller 341 and interrupt controller 342. Reference numerals 343, 344 and 345 denote a data bus, an address bus and a control bus, respectively. CPU 331 controls the operatlon of radio unlt controller 330. Osclllator/frequency dlvider 332 supplles clock slgnals to CPU 331 and dlvldes the clock slgnals to supply approprlate frequency-dlvlded pulses as tlmlng pulses to each sectlon of the moblle telephone apparatus requlrlng them. Address decoder 333 outputs predetermlned operation slgnals to the components ln response to instruction slgnals from CPU 331. ROM 334 stores varlous programs requlred for operation of CPU
331. RAM 335 stores varlous types of data durlng processing for use by CPU 331. Radio controller 336 controls radio section 310 in response to lnstructions from CPU 331. For example, radlo controller 336 sends signals lndlcatlve of avallable frequencles to ;
2 ~ 2 ~
synthesizer 320, sl gnals indicative of an amplificatlon level to power amplifier 316, and signals indicative of modulation parameters to modulator 314. Radio controller 336 receives a step-out signal from synthe-sizer 320 and output power detection signals from poweramplifier 316 and forwards these signals to CPU 331, thereby preventing operational errors.
Audio circuit 337 extracts control signals and audio signals from the received signals demodulated by demodulator 312 and supplies the control signals to control signal processor 338 and the audio signals to telephone unit 400. Audio circuit 337 also supplies a control signal from control signal processor 338 and audio signals from telephone set 400 to modulator 314.
It should be noted that audio circult 337 also arranges the waveform of the control signal to be sent to control slgnal processor 338 in a particular slgnal format and filters the control signal to be supplied to modulator 314. Control signal processor 338 acquires bit and frame synchronization with the control signal from audio circult 337. Malntainlng the requlred synchronlzation, control signal processor 338 converts the serial control slgnals, lncludlng control data recelved from a base statlon, lnto parallel slgnals and converts the parallel control data slgnals to be transmltted to a base station lnto serlal signals. The control signals are set to and from the base statlon vla audlo clrcuit 337.
202~2i'3 Audio circuit controller 339 controls audio circuit 337. Under the control of audio circuit controller 339, for example, audio circuit 337 applies the received signals from demodulator 312 to control signal processor 338 or telephone unit 400 and selectively receives the signals from control signal processor 338 or telephone unit 400. Digital interface 340 interfaces the data communication between radio unit 300 and telephone unit 400. Power controller 341 controls power source 390 and sets a voltage supplied from battery 506 to power source 390 to a predetermined level. The voltage having the predetermined level is supplied to the respective clrcult components.
An operation of the radlo telecommunlcatlon appa-ratus havlng the above-described arrangement accordlng to the flrst embodlment of the present lnventlon wlll be descrlbed below.
Prlor to speech communlcatlon processing in the apparatus of thls embodlment, the apparatus may be swltched from a standby state to an allowable call charge reglstratlon mode by a predetermlned key opera-tlons, e.g., depresslng keys oflFCN 1, ~ , ~ , continuously. After that, an allowable call charge may be reglstered into the apparatus by operatlng ten-keys.
For example, keys of m ~ ln the key sectlon 430 are operated to enter $10 as the allowable call charge, and thls lnput value ls stored ln the ID ROM 370 . ........ . . .
, ~' ' ' , 2~ ,3 constituted by an E2PROM.
The flow of operation shifts to an outgoing call operation in response to the input of a destination telephone number and the send key. Upon this outgoing call operation, over a control channel established between the apparatus and the base station, system data is received from the base station. Information repre-sentative of a charge rate is then extracted from this system data and is stored in the RAM 335.
The base station designates a speech channel for the mobile unit. In accordance with this designation, the mobile unit is tuned to the speech channel, and the base statlon ls also tuned to the speech channel.
Speech communication ls then started through the deslgnated speech channel.
In synchronlsm wlth an establishment of a speech communlcation llnk, the CPU 331 starts to count a speech communlcatlon tlme by uslng an lnternal clock pulse, and sequentlally calculates call charges on the basis of the charge rate stored in the RAM 335 and the count values. The CPU 331 fetches the allowable call charge data from the ROM 370 and compares it with the calcula-tlon results. If it is determined that a call charge exceeds the allowable call charge, the CPU 331 sends a control slgnal for generatlng an alarm slgnal to the audio clrcuit 337. The audlo clrcult 337 sends the alarm slgnal to the loudspeaker 492 or the handset 292~52s5 receiver 498 so as to cause the loudspeaker 492 or the handset receiver 498 to generate an alarm.
The user can confirm from this alarm that the current call charge exceeds the allowable call charge.
Therefore, the speech communication time can be managed in accordance with this alarm.
The above-described operation will be described in more detail below with reference to the flow chart in Fig. 3.
When it ls determined in step 30 that the operatlonal state of the apparatus transits from a standby state to a speech communication state in which a speech communication link is established, the radio section 310 of the apparatus receives signals trans-mitted from the base station over the established speech communicatlon link. The received signals are applied to the control signal processor 338 through the audio clrcult 337. The control slgnal processor 338 detects a synchronization slgnal, an address data addresslng the apparatus, and the followlng system data in the received slgnals. The detected system data are applied to CPU
331 vla bus lines. The system data include lnformation concernlng a charge rate, whlch ls extracted by CPU 331.
CPU 331 stores the extracted charge rate informatlon lnto the ~AM 335 ln step 31. The charge rate infor-matlon, for example, conslsts of ten (10) blts. In step 32, the CPU 331 starts call charge count by startlng to ., . ,: , , 202~626 count a speech communication time, thus starting to calculate a call charge on the basis of the counted time and the charge rate obtained from the data received from the base station. More specifically, CPU 331 calculates a call charge by multiplexing the counted time by the charge rate. In addition, the calculated call charge may be displayed on display unit 450 under the control of CPU 331. Thus, the user may be always informed of the call charge.
In step 33, the CPU 331 compares the calculated call charge with a preset allowable call charge which was stored in the allowable call charge registration mode so as to check whether the current call charge exceeds the allowable call charge. If NO in step 33, the flow advances to step 34, and the CPU 331 calculates the next call charge corresponding to an incremented count time. After it is determined in step 35 that the speech communication link is still established, the flow returns to step 33 in which the current call charge is compared with the allowable call charge.
If the CPU 331 determines that the current call charge exceeds the preset allowable call charge, it starts, for example, the following processing in step 36:
~1) generatlng an alarm from the loudspeaker 492 or the handset recelver 498 in the mobile unit by superposing it on speech;
.
20~626 (2) transmitting an alarm signal to the destina-tion by superposing it on speech signals to be trans-mitted;
(3) displaying an alarm message on the display unit 450;
(4) causing a backlight for the display unit 450 to blink.
Note that these operations may be independently or simultaneously performed.
This lndication processing may be continued until a speech communication link using the speech channel is broken down owing to user's on-hook operations and so on (steps 37 and 38). After that, the apparatus is set in a standby state again.
According to the radio telecommunication apparatus of this embodiment, therefore, long speech communication is determined on the basis of a call charge, and this lengthy talk can be informed to the user.
In the above-mentioned embodiment, while the charge rate is obtained through the speech communication llnk after it ls established, the charge rate may be obtained in advance through a control channel before the speech communlcatlon link ls established.
The second embodlment of the present lnventlon will be descrlbed below wlth reference to the flow chart in Flg. 4.
When lt ls determlned ln ætep 20 that the apparatus : ' .
2~2~526 is set from a standby state to a speech communication state, the CPU 331 receives system data from the base station, reads a charge rate from the system data, and stores it in the RAM 335 in step 21. In step 22, the CPU 331 starts to count a speech communication time so as to start call charge count, and starts to calculate a call charge on the basis of the speech communication time and the charge rate.
In step 23, the CPU 331 compares the calculated call charge with a preset allowable call charge so as to check whether the current call charge exceeds the allowable call charge. If NO in step 23, the flow advances to step 24 to calculate the next call charge by uslng the call charge call count. When the CPU 331 determlnes that the speech communlcatlon llnk ls stlll establlshed, the flow returns to step 23 to compare the current call charge with the allowable call charge.
If the CPU 331 determines in step 23 that the current call charge exceeds the preset allowable call charge, it controls synthesizer 320 so as to supply demodulator 312 wlth signals having frequencies for scannlng the control channel and modulator 314 to be turned off. Consequently, the established speech communlcatlon llnk ls termlnated ln response to the excess of the call charge (step 26). After that, the operatlon returns to the standby state.
Accordlng to the radio telecommunlcatlon apparatus 202~2~
of this embodiment, long speech communication is deter-mined on the basis of a call charge, and the speech communication can be forcibly ended. Therefore, a good economical effect can be expected.
The third embodiment of the present invention will be described below.
Fig. 5 is a flow chart showing an operation sequence of the apparatus of the third embodiment.
In this apparatus, indlcation processing is exe-cuted when an accumulated call charge for a plurality of calls exceeds a second preset allowable call charge.
The second allowable call charge is stored in the ROM
370 by a key-operation in the same manner as in the above-descrlbed embodiments. The accumulated call charge up to the last call is also stored in the ROM
370.
When the apparatus is set from a standby state to a speech communlcation state, the CPU 331 checks in step 40 whether the accumulated call charge exceeds the second preset allowable call charge. If YES in step 40, predetermlned processing indlcatlon and communlcatlon control operatlons of, e.g., lnhlbltlng speech communl-catlon or generatlng an alarm, and lnformlng the user of thls state is performed ln the slmllar manner as descrlbed ln the above-mentloned embodlments (step 42).
If NO in step 40, the flow advances to step 41.
After outgolng call processlng, the CPU 331 recelves 202~626 system data from the base station, reads a charge rate from the system data, and stores it in the RAM 335 in step 43. In step 44, call charge count is started. A
call charge based on this count result is added to the previous accumulated call charge stored in the ROM
370, and the updated accumulated call charge is stored in the RAM 335. In step 45, the CPU 331 compares the accumulated call charge with the second allowable call charge. If the accumulated call charge exceeds the second allowable call charge, the above-described indlcation and communication control operations is performed ln step 42.
If the accumulated call charge does not exceed the second allowable call charge, call charge count is con-tlnued ln step 46. If it ls determined that the speechradlo llnk ls still establlshed ln step 47, the flow returns to step 45 to perform the same declslon proc-esslng as described above.
After the speech communlcatlon llnk ls broken down, the current accumulated call charge ls wrltten ln the ROM 370.
Note that the above~descrlbed indlcatlon and communlcatlon control operatlons can be canceled by clearlng the accumulated call charge stored ln the ROM
370.
Accordlng to the radlo telecommunlcatlon apparatus of thls embodlment, whether the accumulated call charge .,.,, .: ;
. .. .
2~2o626~
exceeds the second allowable call charge can be informed to the user.
The accumulated call charge may be stored in a detachable memory device, e.g. an IC card.
The fourth embodiment of the present invention will be described below with reference to Figs. 1, 2, and 6. In this embodiment, while the apparatus is in a standby state before speech communication, a unit time and a charge rate as call charge units are entered by the key unit 430 and are stored in the ROM 370 in step 50.
Upon operation of the key unit 430, an allowable call charge is entered as a call charge limit allowed for one call, and is stored in the RAM 335 while each input value is checked on the display unit 450.
When outgoing call processing is performed by enter-ing a destination telephone number from the key unit 430 in ~tep 51, the radio unit controller 330 performs out-going call connection processing with respect to the base station through the mobile antenna 200. Upon completion of the connection processing, the apparatus is set in a speech communication state. In this speech communication state, an audible sound signal received through the mobile antenna 200 and the radio section 310 is sent to the loudspeaker 492 through the .~
2020fi~6 audio circuit 337. The audible sound signal input from the microphone 466 is sent to the radio section 310 through the audio circuit 337.
In this radio telecommunication apparatus, count of a speech communication time is started at the same time when a speech communication state is set, and calcula-tion of a call charge is started by using the counted time and the preset charge rate in step 52. In step 53, the call charges are sequentially compared with the present allowable call charge with the lapse of a speech communicatlon time. If it is determined in step 53 that the current call charge exceeds the allowable call charge, the flow advances to step 54 to inform this state to the user. Subsequently, on-hook processing is performed (step 55), and information processing is ended ~step 56).
If the current call charge does not exceed the allowable call charge, the flow advances to step 57 to contlnue call charge count. When it ls determined in step 58 that the line is still connected, the flow returns to step 53. This processing is repeated until the current call charge exceeds the allowable call charge.
The thlrd embodiment may be comblned wlth the flrst, second, or fourth embodlment. Wlth such a combinatlon, an accumulated call charge based on a plurallty of calls can be slmultaneously managed wlth ,. . . ..
2020~
a call charge based on one call.
Still, any other combinations of the above-mentioned embodiments fall into the scope of the present invention. For example, the speech communication link may be terminated after the user is alarmed. In this event, a criterion for a disconnection of the speech communication link is greater than a criterion for an alarm.
