This coding example comprises 9 code words with 280 supposition of digital information frame, and wherein first code word is frame synchronization code word SC, and 8 code words under the surplus record are defined as being used for sending 8 address code words or being used for sending digital word; When being used for sending address code word, second address code word 282 is corresponding with one group of beep-pager, this group beep-pager is designed to a selective reception address code word 282 and to its decoding, when the address code of address code word 282 and this machine " address code " coupling, then receive information subsequently, when running into other address code word or idle code word, stop to receive, in like manner, the 3rd address code word 283 is correspondingly corresponding with second group of beep-pager, 8 groups of beep-pagers is arranged thus respectively with 282,283 ... 289,8 address code words are corresponding; The people who is familiar with this professional technique understands that this addressing method will be convenient to realize the Design of power saving of beep-pager; Frames of voice information 290 is defined as with the digital information frame same time span being arranged, and the beginning of determining first frames of voice information is guided by an idle code word NL, connect voice messaging thereafter, frame swynchronization code SC no longer appears in the later frames of voice information, in the end frames of voice information finish time, and then a preamble 270; This coding example is also determined, a paging is called out and can be comprised that several digital information frames issue several different beep-pagers respectively or several digital information frames are issued some beep-pagers, can also send a voice paging that comprises several frames of voice information simultaneously; This coding example has been realized digital information is mixed the purpose that sends with (simulation) voice messaging, and can guarantee that numeral and two kinds of beep-pagers of voice all correctly receive information separately, and its message length is a variable length.Utilize digitized speech information to transmit voice messaging and be actually digital paging, this embodiment can utilize digital information frame 280 to transmit.

Fig. 3 C shows the simplification time diagram that adopts twice paging calling that this coding example sends by the paging center station, it is guiding that paging is for the first time called out with preamble 270, having sent a certain beep-pager O address code word 284 in the 3rd group of beep-pager in the first digit information frame, is 9 digital word then; Then sent the address code word 286A of a certain beep-pager P in the 5th group of beep-pager, 8 digital word and 4 idle code word NL have then been sent, and then sent the voice messaging 290 of giving beep-pager P ... in voice messaging finish time, sent preamble 270A, indicate the end of a voice messaging transmission, the beginning that has also guided paging for the second time to call out, a certain beep-pager Q had sent address code word 289C during paging was for the second time called out and give the 8th group in the digital information frame, be frames of voice information 290A then by idle code word NL guiding ... sent the preamble 270B that indicates this voice paging end of calling the finish time in frames of voice information, stopped then sending.To describe beep-pager O, P, Q below respectively and receive the process of paging information separately respectively.

Fig. 3 D shows the time diagram of a certain the beep-pager O experience variety of event that belongs to the 3rd group of beep-pager.Beep-pager O is after receiving preamble 270 and first frame synchronization code word SC, begin receiver address code word 284 at the fixed time, because of address code word and this machine address code coupling of receiving, and then receive digital word, when receiving second address code word 286A, stop to receive digital word, enter electricity-saving state, after this received frame synchronization code word SC and the 3rd group address code word on time, but all, address code word and this machine address code do not change electricity-saving state over to because of matching, during sending frames of voice information 290, change the preamble state of seeking of receiving over to because of can not receive the frame synchronization code word, after receiving preamble 270A, begin received frame synchronization code word SC and the 3rd group address code word again, send voice paging 290A for the second time at the paging center station ... Shi Zaici changes preamble over to and receives and to seek state, waits to receive behind the preamble 270B because of can not receive frame synchronization code word SC to change the preamble receipts over to and seek state (sleep).Beep-pager O can be that alphanumeric pager also can be a speech digit mixing beep-pager in this example.

Fig. 3 E shows the time diagram of a certain the beep-pager P experience variety of event that belongs to the 5th group of beep-pager.Beep-pager P is after receiving preamble 270, received frame synchronization code word SC and the 5th group address code word 286A, when receiving address code word 286A, confirm this address code word and this machine address code coupling through decoding, and sign has voice paging information (being identified by the function digit in the address code), beep-pager P receives digital information, when receiving idle code word NL constantly at frame synchronization code word SC, change receiving speech information 290 over to ... during receiving speech information (analog signal), the digit receiver of beep-pager P changes the preamble state of seeking of receiving over to, when receiving preamble 270A, finishing voice messaging receives, change received frame synchronous code SC and address code state over to, send out voice paging information 290A for the second time at the paging center station ... the time beep-pager P enter to receive and seek the preamble state, after receiving preamble 270B, enter receipts and seek preamble state (sleep) because of can not receive frame swynchronization code SC.Beep-pager P is a speech digit mixing beep-pager.

Fig. 3 F shows the time diagram of a certain the beep-pager Q experience variety of event that belongs to the 8th group.Beep-pager Q just enters economize on electricity and receives word synchronous code SC and the 8th group address sign indicating number state after receipts are sought first preamble 270, to the address code of receiving 289,289A, 289B can not mate with this machine address code through decoding, after receiving address code word 289B during received frame synchronous code SC, can not receive frame swynchronization code SC changes preamble over to and receives the state of seeking, after receiving preamble 270A, received address code word 289C, through decoding and this machine address code coupling and sign voice messaging is arranged, beep-pager receives constantly that at frame swynchronization code SC next the space code word NL sign that sends at the paging center station is voice messaging, change voice over to and receive, up to receiving that preamble 270B just stops the voice reception and change preamble over to receiving the state (sleep) of seeking.Because paging center does not send digital word after standing in and sending address code word 289C, so beep-pager Q has only received voice paging information.The people who is familiar with this professional technique can recognize, only sends voice paging information as long as the paging center station limits certain group beep-pager, just can have one group of simple voice paging machine to work in this net.Certainly this routine beep-pager Q is remained a speech digit mixed type beep-pager, just received the special case of a pure voice paging.This shows that Fig. 3 F has also provided the time diagram of sending out voice paging pure to beep-pager.

Voice messaging from the present invention to beep-pager that can also broadcast the long period (surpassing the beep-pager storage voice messaging time) among is pure voice broadcast service mode, the front is mentioned in the coding example, in the presumptive address code word the 30th, 29 bit function sign indicating numbers be 11 o'clock be pure voice broadcast service mode, receiving function code when the voice paging machine so is 11 and during with the address code word of this machine address code coupling, just controlling beep-pager directly broadcasts the voice messaging of receiving to the user by power amplifier, this pure voice broadcast service mode is identical with the time diagram of the shown receiving speech information of Fig. 3 F, and the action that different just beep-pager hardware is taked is difference slightly.Also can further specify below this point.

Above Fig. 3 D, Fig. 3 E, Fig. 3 F time chart understand that three beep-pagers of O, P, Q that adhere to three different groups in the patent working example of the present invention separately receive the time diagram of pure digi-tal paging, digital speech mixing paging, three kinds of situations of pure voice paging respectively, the personnel that are familiar with this professional technique can recognize the operating time figure of the N portion beep-pager that is assigned in 8 groups thus, (N is the integer smaller or equal to addressing capabilities) and the time diagram that receives numeral, digital speech mixing, three kinds of situations of pure voice.

Fig. 4 shows paging center in the invention process example and stands among the read-only memory ROM217 program control flow chart of work down, ＂ Y ＂ among the figure represents the criterion establishment, ＂ N ＂ among the figure represents that criterion is false, and Fig. 4 has also described the workflow that various paging informations are sent at paging center discussed above station.Fig. 4 center 410 is inlets of speech digit processor 200 power-on resets, system parameters is carried out initialization, promptly change frame 411 then over to, whether have call, differentiate as then not changing frame 412 over to whether artificial input application is arranged if differentiating, artificial input application is from keyboard 213, if inartificial input applies for then changes frame 413 over to check whether the paging call queuing is arranged in page queue, as do not have the paging call queuing, and forward frame 411 to through 413A again, repeat said process; Frame 411,412,413 has been formed the scheduler program of this flow chart, according to call in the system, artificial input application with send having or not of paging call queuing and arrange three kinds of task coordinates runnings.The source of collecting the paging calling has two kinds, a kind of from telephone network, a kind of operator from the paging center station, when call, telephone line interface plate 110 again through interface 241A is given microcomputer with digital signal form through speech data interface board 241 with call signal, when program is carried out frame 411, judging has call, forward 420 then to, frame 420 sends control signal will have the telephone line of calling to connect through telephone line interface 110 and speech digit interface board 241, again by frame 421 control speech digit interface boards 241 to the telephone subscriber send " be here * * paging center; please the dialing sign indicating number " phonetic order, collect the number that users extract by frame 422 controls then.Automatically collect the characteristics of call according to the present invention, as follows to call dialing protocol definition:

1. voice, alphanumeric pager unification are numbered, and number is 6 10 system numbers.Can certainly be defined as more multidigit or still less position, the viewing system scale to determine;

2. the paging code can be made up of 0 to 30 decimal number, directly follows after beep-pager coding, can certainly determine more or lessly, when pulling out when promptly not pulling out the paging code into 0, shows it is pure voice paging.

3. number represent paging to call out the end of dialing with " # ".

4. system is that every beep-pager is offered a messages in mailbox, and number is to add 1 (or more multidigit) decimal system number before the paging number.

5. number representing messages in mailbox to call out dialing with " # " finishes.

After frame 422 harvests number.Whether change frame 423 differentiations over to is that paging call is called out, what now supposition was received is that paging call is called out, flow process changes frame 440 over to, to receive that paging code and digital code deposit in the ram memory, enter frame 441 then, send " please stay voice paging information; no information is asked on-hook " phonetic order by frame 441 control system to the telephone subscriber, change frame 442 then over to, frame 442 control speech digit interface boards 241 convert the voice messaging on the telephone line to digital information and store among the RAM, promptly begin recording, then by frame 443 starting timer TIMER1 timing, the voice messaging of the each paging of the invention process example supposition qualification is less than and equals 20 seconds, can certainly be defined as longer or shorter.Fig. 4 center 444 judges whether timer TIMER1 overtime, and the not overtime frame 445 that changes over to is declared whether on-hook of user, before TIMER1 is overtime user's on-hook have two kinds may, a kind of is the on-hook that finishes of voice paging information, a kind of is not have the on-hook of voice paging information; Frame 450 during according to on-hook TIMER1 whether greater than 2 seconds fixed voice that whether have of betraing, there is not voice messaging as betraing to be decided to be less than 2 seconds, record down the voice messaging that exists among the RAM by frame 451 removings, flow process flows into frame 452 controls and takes out stitches then and to finish conversion from the beep-pager sign indicating number to the pager address sign indicating number according to the pager number of having preserved among the RAM and digital paging code and by above-described coding protocol by frame 453, generate pure digi-tal paging call information, and be inserted into and go in the paging call queue etc. to wait upon transmission, page queue is stored in the disk 215; If when receiving on-hook signal, frame 450 judges that the TIMER1 timing greater than 2 seconds, then has been judged to be voice messaging; If before TIMER1 is overtime, can not receive on-hook signal, then also explanation has a voice messaging and longer, is sent to the telephone subscriber by frame 446: " overtime, as please to use the messages in mailbox function ", change frame 447 then over to, as long as voice messaging is arranged as can be seen,, all change frame 447 over to here no matter whether overtime, stop recording by frame 447, overtime voice paging information was only recorded preceding 20 seconds, taken out stitches by frame 448 then, the cut-out telephone line is connected with the speech digit interface board; Then by frame 449 according to the pager number among the RAM, digital paging code and the phonetic code recorded, and by above-described coding protocol generation paging call information, send into the paging call queue, preparation is sent, so far, the call of once setting up paging disposes, and program circuit is got back to the inlet of 441 frames again, enters scheduler program; Above-described call handling process comprised flow process that telephone callers sets up the pure digi-tal paging and call out, set up digital speech mixes the flow process of calling out, if call is after extracting pager number, do not extract the paging code, import voice messaging then, just can set up a pure voice paging and call out, its workflow is identical with setting up speech digit mixing paging callwork flow process.

Can not issue beep-pager with the voice paging information mode to the voice messaging of length (20 seconds) when limiting surpassing, the pure digi-tal beep-pager can not receive voice, and the invention process example solves by the method that allows to set up messages in mailbox.Be described below setting up the leave word call call flows below in conjunction with Fig. 4: when a leave word call is called out, frame 411 judges that call is arranged, connect telephone line through frame 420, send to the telephone subscriber by frame 421 control system: " be here * * central station; ask dialing " voice messaging, the telephone subscriber extracts messages in mailbox number (7 figure place) and dialing end mark " # " by call dialing agreement, frame 422 control system receive these numbers, frame 423 is not that paging is called out according to " # " number differentiation, so change frame 430 over to, frame 430 is extracted a function code by the prompting telephone subscriber, and to determine to set up messages in mailbox still be the inquiry messages in mailbox, the calling of setting up messages in mailbox is forwarded to frame 431, by frame 431 control system and telephone subscriber's session establishment messages in mailbox, messages in mailbox is built in the disk 215; Give the telephone subscriber language message that the user will inquire about to query call by frame 432 and telephone subscriber's dialogue.Also certain cryptographic means will be arranged in the inquiry messages in mailbox process, this realizes in frame 432.Frame 433 is finished the control of taking out stitches, and program changes frame 411 over to then, enters scheduler program.

The invention process example is an automatic paging system, but also allows the operator to pass through keyboard 213 and microphone 243 input paging informations, that is to say the needs that also can adapt to artificial paging centers.Fig. 4 center 412 constantly detects the artificial input application that does not have from keyboard 213, if have then forward frame 470 to, 470 control prompting operation persons import data such as pager number, paging code and the selection of paging classification on keyboard 213 by frame, frame 470 receives these data and is kept among the RAM212, if set up the pure digi-tal paging, then finish Data Format Transform, generate the paging conform to top described paging code agreement and call out by frame 453, and be inserted into go in the page queue etc. to be sent; If set up language digit mixing paging information, then utilize microphone input voice messaging by frame 474 control system prompting user, voice messaging converts digital form to through speech data interface board 241, be recorded among the RAM, distinguish that by frame 475 End of Tape then changes frame 449 over to, finish Data Format Transform by frame 449 control, set up a digital voice mixing paging call out join go in the page queue etc. to be sent; The operator can also select to set up pure voice paging on keyboard, at this moment, the operator only imports pager number and selects to set up pure voice paging mode from keyboard 213,470 of frames have been received pager number, like this, frame 449 will generate a pure voice paging call out be put into go in the page queue etc. to be sent; System also allows the operator to set up the paging information of pure voice broadcast service mode, at this moment the operator imports pager number (can import, a group or a group pager number) and selects voice broadcast service paging mode then, when frame 472 identifies the paging of broadcast mode, on address code function code position, set up broadcast flag " 11 ", then by frame 474 control recorded speech information, frame 475 is checked through the voice end mark and just forwards frame 449 to, set up the paging of a pure voice broadcast service paging mode by frame 449 controls and call out, send into page queue and be ready for sending.After this, program changes frame 411 again over to, reenters scheduler program.

Have a look the workflow that paging information is sent at the paging center station in conjunction with Fig. 4.When central station has been set up a page queue, when carrying out frame 413, program can find to have at present paging information etc. to be sent, observing Fig. 4 can see, frame 460 will be controlled and take out a paging information according to the principle of first in first out from formation (disk 215) and be stored among the RAM212, process block 461 judges according to the function digit in the address of paging sign indicating number whether voice paging is arranged, if voice paging arranged then forward frame 462 to, by frame 462 control system (if any earlier with address of paging sign indicating number and paging code, pure voice paging is not had) send into encoder 261 through interface 261A, and control switch 262 is connected 261B line and 262A line, encoder 261 sends the address of paging code word by the time series of Fig. 3 C, digital word, after distributing last digital word, encoder is broadcast idle code word in the time before next frame begins, send an idle code word zero hour at next frame then, switch 462 is switched, 251B line and 262A line are connected, by frame 463 control system voice paging information (digital form) is sent into VODER plate 251 through interface 251A then and the voice messaging of digital form is reduced into analog voice signal warp 251B launches through antenna 320 again through transmitter 310 to 262A; The time that frame 463 control voice send takies the time of L frame, the voice messaging unvoiced speech filling of less than one frame, when the last frame voice messaging distributes, frame 463 control switchs switch to 261B and 262A connected state, controlled encoder 261 sends a preamble simultaneously, indicates a voice paging normal termination.Frame 465 is after distributing a paging formation to be put, write down in order the number of times that this paging information is issued, and adjusts the order of paging in formation, and program is got back to frame 411 again then, enters scheduler program.Described the flow process of speech digit voice mixing paging above, observed Fig. 4 as can be seen, sent the pure digi-tal paging and just saved transmission voice program frame 463, sent digital paging by frame 464, frame 464 is identical on function with frame 462; Because of free of data in the paging information, then directly change frame 463 over to when the transmission of pure voice paging difference only is to carry out frame 462, all the other are identical with transmission speech digit mixing paging all,

Speech digit mixing beep-pager shown in Figure 5 removes VODER 530 and has just constituted digital beep-pager 2001 in the invention process example, and the personnel that understand this professional technique are not difficult to find out that all being included in speech digit mixing beep-pager shown in Figure 5 about 2001 principle of compositionality in the digital beep-pager has suffered.

Fig. 6 is the workflow diagram of control program among the ROM of speech digit beep-pager 1001." Y " expression criterion among the figure is set up, and " N " expression criterion among the figure is false.Frame 600 is power-on reset and initialize routine, makes each variable that initial state is set, and information such as group under the address code among the EEPROM, this beep-pager is read among the RAM, and sent the specific warnings sound to the user and represent that this machine enters operating state; The program of frame 610 is made as timing constant C 1 (C1 is confirmed as removing to receive a preamble T1 every the C1 time can guarantee to receive preamble T1) with timer TIMER1, allows TIMER1 to interrupt then, and TIMER1 begins to subtract counting; Flow process enters frame 680 then, checks whether query key is pressed, as presses after 681,682 frames response inquiry and enter frame 683, does not enter sleep state by the next frame 683 that directly enters as query key.Frame 620 is inlets that TIMER1 interrupts, when being 0, TIMER1 interrupts, beep-pager is waken up from sleep state, and program changes frame 611 over to and removes to receive preamble T1, then enters frame 612 and judges whether to have received preamble T1, if can not receive and just enter frame 617 replacement TIMER1=C1, beginning regularly enters frame 683 once more through frame 680 then and enters sleep, and so forth, just control beep-pager 1001 at regular intervals and remove to receive preamble one time, till receiving; By frame 611,612,617,620,680,683 this section flow processs of forming are that the beep-pager receipts are sought the preamble flow process, wake up once from sleep every the TIMER1 timing, see whether can receive preamble, as received that preamble just wakes up from sleep, enter the digital information state that receives; Frame 613 is the inlets that receive the digital information state, frame 613 regularly is C2 with timer TIMER1 at first, (C2＜C1 but greater than a frame time) changes frame 614 received frame synchronization code word SC then over to, by previously described paging code and format agreement as can be known, call out if any paging, must information frame behind the preamble, the information frame beginning must be a frame synchronization code word SC, suppose that now frame 614 received frame synchronization code word SC, flow process changes frame 640 over to and removes to receive the address code word that belongs to this beep-pager, this example has supposed that beep-pager 1001 belongs to the 3rd group, so frame 640 is wanted the distance between calculated address code word and the frame swynchronization code, goes to receive the corresponding address code word on time.Utilize the frame synchronization code word to realize synchronously and reception binary digital signal and timing technology that this is a known technology for those skilled in the art.Suppose that now frame 640 control single chip computers 520 have received corresponding address code word, among the RAM of frame 640 control single chip computers with its existence 520, change frame 641 then over to and go decoding, judge whether to be complementary with this pager address coding, if do not match, flow process changes 642 over to, timer TIMER2 is set at the time interval just in time finishes time of beginning to next frame swynchronization code with this address code word, be TIMER2=C4, flow process enters frame 683 through frame 680 and enters sleep then, the reception flow process is waken up and just in time makes flow process enter frame 614 again when timer TIMER2 takes place to interrupt, go to receive next frame swynchronization code, next go to receive corresponding address code word in the next frame again, when receiving the address code word that mates with this machine, flow process just can forward frame 643 to.From this section flow process as can be seen, this is the flow process that realizes receiving the frame synchronization code word and receive the appropriate address code word, this section flow process as can be seen, this is the flow process that realizes receiving the frame synchronization code word and receive the appropriate address code word, except that the frame synchronization code word and the appropriate address code word time, flow process all will arrive frames 683 through frame 680 at last enter sleep state.That wake the reception flow process up is two timer TIMER1 and TIMER2, goes after being waken up by TIMER1 to receive and seeks preamble, has only received that preamble just can allow TIMER2 regularly to interrupt, and goes to receive and seeks frame swynchronization code; Observing this section flow process also can find, before entering received frame synchronous code SC, regularly is C2 by frame 613 with timer TIMER1, (C3＜C2＜C1), like this, if do not receive frame swynchronization code in the time at C2, then TIMER1 sends regularly and interrupts, and makes flow process enter frame 611 again and restarts to receive and seek preamble.

641 pairs of address codes of receiving of flow process center are deciphered, as the address code of receiving and this machine address code coupling flow process flows to frame 643, judged whether voice messaging according to function code, if any voice messaging, flow process changes frame 644 over to, deposits function digit in marking variable FLAG1 and changes 645 reception digital informations then over to.From the coding protocol introduced previously as can be known, if pure voice paging has more than one bell idles at least after address code,, all to change frame 645 over to and go to receive digital information so comprise pure voice paging.Frame 646, frame 647 judge whether it is address code and bell idles respectively, this all end of designation number information of two sign indicating numbers, to pure voice paging, frame 647 is judged when having received a bell idles, changing frame 650 differentiations (FLAG1=11) over to is broadcast message, and flow process flows to frame 670 in this way, and frame 670 sends specific alerting tone 3, remind the user that broadcast message will be arranged, directly deliver to 535 broadcasts of power amplifier 534 promotion loud speakers by the audio signal that frame 671 control sound-compound-circuits 532 are sent 517A here; Not broadcast message then change frame 651 over to and differentiate whether voice paging information is arranged if frame 650 is differentiated, if any then changing frame 660 over to, send beginning recorded audio signals by interface microcontroller 520F to VODER interface circuit 531 by frame 660 programs, the audio signal that sound-compound-circuit 532 is sent 517A here is transformed into digital signal stores in the memory 533, and this Recording Process is till single-chip microcomputer sends when stopping recorded audio signals; Start recording back flow process and enter frame 661, frame 661 program control single-chip microcomputers 520 receive preamble T1, differentiate whether received preamble by frame 662, as can not receive and forward frame 661 to and continue to receive; By above-described coding protocol as can be known, voice messaging finishes that a preamble must be arranged, therefore, after voice messaging finished, preamble had been received in frame 662 judgements, forward frame 663 to, sent to VODER interface 531 by frame 663 control single chip computers 520 and to stop recorded audio signals, VODER 530 finishes recording, and flow process enters frame 664 then, send alerting tone 2, the prompting user has voice paging to arrive; An if pure digi-tal paging, after frame 645 control single chip computers are received digital information, through frame 646,647,648 judgements are negative, flow process enters frame 649, data are saved among the RAM of single-chip microcomputer 520, if digital information length surpasses a frame, frame 648 directly changes flow process over to frame 645, does not preserve the frame synchronization code word, when finishing, digital information must have a kind of end mark (address code word or idle code word) to occur, now supposition is idle code word, and this time-frame 647 detects an idle code word, changes flow process over to frame 650, cause is the pure digi-tal paging, frame 650,651 are negative, and flow process forwards frame 652 to and sends alerting tone 1, and the prompting user has received digital paging.After this flow process is got back to frame 680; Frame 680 is used for inquiring user and whether supresses query key, if the user presses query key, flow process flows to frame 681, stop alarm, enter frame 682 control single chip computers 520 then the digital information of receiving is delivered to LCD display 521 demonstrations by 520B, control single chip computer 520 sends the playback control signal by 520F to VODER interface circuit 531 simultaneously, control sound-compound-circuit 532 takes out the voice messaging that is stored in the memory 533, be reduced into voice messaging through sound-compound-circuit 532, delivering to loud speaker 535 by power amplifier 534 plays, finish flow process and enter frame 683, enter sleep state.When entering frame 683 frames, frame 683 will be put TIMER1=C1, allow timer TIMER1 to interrupt, and then enter sleep.

The workflow of ROM program can be seen from speech digit mixing beep-pager shown in Figure 6, it can receive the pure digi-tal paging information, therefore among the present invention among the ROM of pure digi-tal beep-pager the program workflow be included among Fig. 6 fully, just the process block about voice recording and playback can not be activated, so do not describe in addition about the workflow diagram of ROM program in the pure digi-tal beep-pager among the present invention.
