Description

The redirecting call route of telephone method and apparatus
The present invention relates to a kind of method and apparatus, the caller phone user that it is used for public switched telephone network PSTN communicates being redirected of route when calling out called phone.
The expansion with the private wire network scale carried out along with telecommunication service, the calling subscriber of public switched telephone network PSTN is when calling out a long-distance called subscriber (also can be the user who charges by net telephone expenses or farm work expense in the local network), except continuing by PSTN toll route routinely, on toll route, also have other optional bypass route, such as IP phone (as telecommunications IP phonecard 17900, UNICOM's IP phonecard 17910, Jitong's IP phonecard 17920 etc.), the world is subjected to pay phone (as 108 business), private wire network is (as forces network, Railway Communication, power telecom network etc.) and dedicated communication line etc.Provide these long distance bypass routes of service to the public, their communication cost can be lower than the long distance communication expense of routine, particularly the IP phone route.
Use process that this class bypass route carries out trunk call normally: at first dialing provides the access of this service telephone number (normally local pstn telephone), after waiting this access telephone answering, the user account number, the password that show dialing user identity by voice prompting input, the called telephone number of input after confirming, at different bypass route or service providers, in operating process, also need the input prompt languages to select and other necessary button.The button that such operating process will be imported may be about 30, operate cumbersomely, and make mistakes easily.
Internet address (http://www.jitongnetwork.net/ip/dialer.htm) has been introduced a kind of " Personal Handyphone System " networking telephone manager (dialer), it can finish the automatic dialing of IP phonecard access information, has solved the problem that the IP phonecard dialing makes mistakes easily.Using method by the said dialer of this network address, when calling, if behind the called phone number, add " # ",, whether add behind the called phone number that promptly " # " distinguishes the sign that whether uses the IP phone route just this dialer enters the dialing of IP state.Like this, use the people of this dialer, necessary autotelic use IP phonecard when calling, and know that this called phone can be by this IP phonecard connection.Owing to the custom of calling of long-term formation, people can be easy to forget and need add the button that other is extra outside the called phone number.Also have, provide the service commercial city of this class long distance bypass route service that the part in zone, public switched telephone network PSTN long distance service can only be provided at present, thereby whether want everyone know the called phone that will beat can be used the long distance bypass route than the low communication expense, not a thing easily.Have, this dialer is after having imported the called phone number and having added " # ", just begins the access phone of call ip phone card again, and the Call Waiting time is longer.Can learn that from the method to set up that this network address is introduced it can only be provided with an IP phonecard.Because the coverage difference that provides of different IP phone service providers can make a phone call often will for the coverage of another IP phone service provider in reality, and this dialer is not supported the automatic dialing that second or above IP phonecard insert.
The purpose of this invention is to provide a kind of like this method and apparatus, it can select the possible bypass route than the low communication expense for this calling automatically when the caller phone user dials called phone in the usual way.
Another object of the present invention is to reduce the Call Waiting time as much as possible when finishing the calling to called phone than the bypass route of low communication expense.
Of the present invention to also have a purpose be to have a plurality of availablely than low communication expense bypass route simultaneously, uses the zone of calling than the low communication expense thereby increased.
The invention provides a kind of reorientation method of call route, at first the present invention sets up the bypass routing table, it preserve can use than the access of low communication expense bypass route and the needed data of operating process of calling out called phone.Call in the usual way and this calling can be when continuing than low communication expense bypass route the phone calling subscriber, automatically be redirected on the bypass route in order to realize to call out, the present invention sets up the office direction tables of data, and it preserves the office direction data that can and need to finish by the bypass route automatically redirected call.The said method of the present invention is handled call according to the following steps: behind the caller phone off-hook, receive the called phone number that caller phone sends, imported or received at the called phone number in the process of each called phone number all called phone number preceding office to the part (world, the prefix part of national distance area code or indication called phone office direction) compares with office direction data in the office direction tables of data, judge whether the bypass route of this called phone, if the bypass route of this called phone is arranged, calling is redirected on the bypass route to the dial train that public switched telephone network PSTN sends by changing so, and finishes the calling of caller phone called phone by the bypass route; Otherwise, by PSTN routinely route finish continuing between the calling and called.
The data that the bypass routing table will be preserved have: access telephone number, user identification code and the end of calling code of the bypass route that can use.User identification code comprises user account number, password, must import the code (as representing a period of time of delaying time with *) of the data (as requiring input prompt languages etc.) and the expression particular methods of operation of button correspondence before the called phone number.End of calling code is the data that must import the button correspondence after the called phone number, is set to sky for the bypass route end of calling code that does not need end of calling code.
Because the coverage difference that different bypass route service merchants provides, in order to enlarge the scope than the call of low communication expense, bypass routing table of the present invention can be provided with a plurality of bypass routes.When a plurality of bypass route is arranged in the bypass routing table, need the bypass Route Distinguisher of one of them bypass route of unique appointment, this bypass Route Distinguisher can be the arrangement sequence number of bypass route in the bypass routing table, it also can be the access telephone number (because access telephone number difference of each bypass route) of each bypass route, can also be in the bypass routing table, to increase an authentication code field again, be used for each bypass route of unique appointment.
Table 1 has been described the structure of the said bypass routing table of the present invention, and has provided the data that are provided with of several bypass routes.Sequence number is that 1 bypass route is UNICOM's IP phonecard in the table 1, and the Chinese prompting is selected in first " 1 " expression of user identification code; Sequence number is that 2 bypass route is Jitong's IP phonecard, and English prompts is selected in first " 2 " expression of user identification code; Sequence number is that 3 bypass route is Hong Kong New World phonecard, and the Chinese prompting is selected in first " 3 " expression of user identification code." * " in the user identification code indicates to delay time a period of time, is not the dtmf signal that will send." # " in user identification code and the end of calling code is the dtmf signal " # " that will send.Table 1: bypass routing table

The said process that calling is redirected to the bypass route of the present invention is: the connection line that cuts off caller phone and public switched telephone network PSTN, and make the telephone wire that connects the PSTN end be in hook state, the time of one section necessity of time-delay (the cut-out approval time that surpasses switch), control telephone wire again and be in off hook state; Then send the access telephone number of current calling station in the bypass routing table of correspondence, calling is redirected on the bypass route to PSTN; After waiting the access telephone answering of this bypass route, send user identification code, called phone number and the end of calling code of this bypass route again; And then the connection line between recovery caller phone and the PSTN.
Realize device of the present invention in the back in conjunction with the accompanying drawings, but also not only be confined to accompanying drawing with embodiment.
Fig. 1 is an application structure block diagram of the present invention, and it has comprised one embodiment of the present of invention.
The application structure block diagram of a better embodiment of the said redirecting call route of telephone method of the present invention as shown in Figure 1, the said device of the present invention (11) is positioned between caller phone terminal (10) and the public switched telephone network PSTN (24).Here said telephone terminal comprises telephone set, facsimile machine, modulator-demodulator, group telephone, subscriber exchange etc.
The said a kind of device of the present invention (11) by CPU (16), memory cell (12), DTMF receiving circuit (17), DTMF transtation mission circuit (20), pluck/on-hook detection circuit (18), pluck/on-hook control circuit (19), telephone wire control circuit (21) and power circuit (22) form, memory cell is wherein preserved the data of said bypass routing table of the present invention (14) and office direction tables of data (15).
The course of work of the device of realizing according to the said method of the present invention (11) is as follows: plucking/on-hook detection circuit after (18) detect caller phone terminal (10) off-hook, CPU (16) receives the called phone number that caller phone sends by DTMF receiving circuit (17), imported or when receiving each called phone number, all searched the bypass route that office direction tables of data (15) judges whether this called phone at the called phone number, if the bypass route of this called phone is arranged, use phone line control circuit (21) to cut off the connection line of caller phone terminal (10) and switched telephone network PSTN (24) so, and by pluck/on-hook control circuit (19) makes the telephone wire that connects the PSTN end be in hook state, the time of one section necessity of time-delay, control telephone wire again and be in off hook state, then control DTMF transtation mission circuit (20) and send access telephone number in the corresponding bypass routing table of this calling, calling is redirected on the bypass route, after waiting the access telephone answering of this bypass route, control the user identification code that DTMF transtation mission circuit (20) sends this bypass route again, called phone number and end of calling code, thereby finish the calling subscriber by of the calling of bypass route, and then control telephone wire control circuit (21) connects the telephone line between caller phone and the PSTN to the called subscriber; Otherwise, finish continuing between the calling and called by the conventional route of PSTN.According to the above-mentioned course of work, when the caller phone user dialed called phone in the usual way, the said device of the present invention (11) can be automatically may and need be redirected to each on the bypass route by the phone that the bypass route is finished calling.
The connection line with phone line control circuit (21) cut-out caller phone terminal (10) and switched telephone network PSTN (24) in the above-mentioned course of work can begin after the called phone number has been imported in caller; Just begin in the time of also can receiving the called phone prefix part identical, can reduce the connecting time of redirected call process like this in CPU (16) with office direction data in the office direction tables of data (15).
During the connection line of caller phone terminal (10) and switched telephone network PSTN (24) is cut off, telephone wire control circuit (21) also needs to power to caller phone terminal (10), CPU (16) make caller phone terminal (10) obtain the JA(junction ambient) similar, so that can continue further part that the reception caller phone sends the called phone number and judge whether on-hook of caller phone to PSTN.
Judge whether the access phone of bypass route has replied two kinds of methods, the one, after sending the access telephone number of bypass route, wait for a sufficiently long time passively (the maximum connecting time that surpasses switch), just think that this access phone replys (dialer of prior art adopt be this method), the shortcoming of this method is that the Call Waiting time is longer, and can't judge that inserting phone does not connect (busy tone).Whether the present invention initiatively discerns the access phone by call signal tone detection circuit (23) and replys, after sending the access telephone number of bypass route, returning discernible signal on the telephone wire has: busy tone, ring-back tone and access phone reply speech, call signal tone detection circuit (23) becomes pulse signal to give CPU (16) conversion of signals on the circuit, discern judgement by CPU (16), if busy tone, then suspended call re-orientation processes; If ring-back tone then waits telephone answering to be accessed; If speech thinks that then inserting phone replys, and can send follow-up call processing signal to the bypass route.
Call out in the redirection process of route in CPU (16), if detect the access busy call of caller phone on-hook or bypass route, the then re-orientation processes of suspended call route.
The said device of the present invention (11) also has a parameter that state is set except being operated in the call route processing procedure of introducing previously, and current working state can be provided with mode such as switch and selects by importing specific coded data or employing.When being operated in parameter state being set, CPU (16) is finished the setting to bypass routing table (14) and office direction tables of data (15) data.The data that are provided with can go up input with device (11) direct-connected caller phone terminals (10), also can send the said device of the present invention (11) after encoded (such as dtmf signal) to by the data that PSTN will be provided with at far-end, DTMF receiving circuit (17) will be provided with data shift signal and become data are set and give CPU (16), handle in the write storage unit (12) of back bypass routing table (14) and office direction tables of data (15) accordingly through CPU (16), or original data are made amendment.If a Computer Communications Interface (such as RS232C) is set in CPU (16), perhaps CPU (16) itself is exactly a computer, so being provided with to use a computer and finishing bypass routing table (14) and office direction tables of data (15) data.
The main task of the CPU of Fig. 1 (16) is according to the said method of the present invention calling subscriber's call to be handled, to there be the called phone of identical office direction to be redirected on the bypass route with office direction tables of data (15), and finish calling called phone through the bypass route.Its core can be single-chip microcomputer (MPU), microprocessor (CPU), digital signal processor (DSP), also can be computer (particularly handling the application scenario of multiplex telephony at the same time).CPU (16) also must have necessary input/output interface ability simultaneously, pluck/the hook state input such as 1 of needs, 1 telephone wire on/off control output and 1 plucks/and hook state control exports, DTMF receives and sends needed digital signal all is 4, receive and transtation mission circuit when possessing ternary interface capability at DTMF, can shared 4 two-way input/output interfaces finish reception and transmission, also need necessary read when DTMF receiving circuit (17) and DTMF transtation mission circuit (20) are carried out the I/O operation dtmf signal.If what CPU (16) was selected for use is the microprocessor (CPU) that does not have input/output interface, then must expand necessary input/output interface circuit at selected microprocessor.
The memory cell of Fig. 1 (12) is used for preserving the working procedure (13) that carries out call processing and parameter setting according to the said method of the present invention, and the data of bypass routing table of the present invention (14) and office direction tables of data (15).Memory cell (12) can be integrated circuit memories such as ROM, EPROM, EEPROM, RAM, flash memory, also can be computer External memory equipments such as floppy disk, hard disk, can also be magnetic card, IC-card etc.In memory cell (12) when being integrated circuit memory, it can be a chip independently, also can be the memory (such as program storage in the single-chip microcomputer and data storage) of other IC interior.Program (13), bypass routing table (14) and office direction tables of data (15) can be kept in the same or same class memory, also can be kept at respectively in the different memories.The data of bypass routing table (14) and office direction tables of data (15) can also be stored in other database, or and the shared same data of other database, CPU (16) obtains needed data by the read data storehouse.
The task of the plucking of Fig. 1/on-hook detection circuit (18) is that detecting caller phone current is off hook state or hook state.The feed voltage of SPC digital switch is-48V, and under normal circumstances, more than 44V, off-hook voltage is 6V to 12V to the on-hook voltage of telephone subscriber's end, and we can finish with voltage detecting circuit and pluck/detection of hook state like this.
The task of the DTMF receiving circuit (17) of Fig. 1 is to become digital signal to give CPU (16) the dtmf dialing conversion of signals that caller phone sends, and its core circuit can adopt the MC145436 of MOTOROLA company production or the double voice multi-frequency receiver of the MT8870 model that MITEL company produces.
The task of the DTMF transtation mission circuit (20) of Fig. 1 is to become touch-tone signal to send to PSTN the redirected dial train data transaction that CPU (16) control is exported, and its core circuit can adopt the auxiliary dial device of the UM91531 model of UMC's production.
The task of the telephone wire control circuit (21) of Fig. 1 is being switched on or switched off of telephone line between control caller phone terminal (10) and the switched telephone network PSTN (24), and at caller phone and PSTN off period to caller phone terminal (10) power supply, so that CPU (16) can continue dtmf signal that the reception caller phone sends and judge whether on-hook of caller phone.The executive component of telephone wire control circuit (21) can adopt relay or other switching circuit.Telephone wire control circuit (21) can be 48V (feed voltage of SPC digital switch) to the supply power voltage of caller phone terminal (10); Because the close together of device (11) and caller phone terminal (10), supply power voltage also can be 24V (feed voltages of some subscriber exchanges).When using the 24V supply power voltage, need to adjust and pluck/the detection magnitude of voltage of on-hook detection circuit (18).
The plucking of Fig. 1/task of on-hook control circuit (19) is to make PSTN that this user's telephone line is in off-hook or hook state under the control of CPU (16), so that dial again to PSTN calling is redirected on the bypass route.Generally speaking, the D.C. resistance of telephone set is smaller or equal to 300 ohm, so we can use a switch element (such as switching transistor) control whether a dummy resistance smaller or equal to 300 ohm to be connected to two of PSTN user telephone line to bring in and realize that PSTN is in off-hook or hook state to this user's telephone line.Concrete control procedure is: after CPU (16) is cut off the connection line of caller phone and PSTN by telephone wire control circuit (21), CPU (16) output on-hook control signal (such as 0 level) makes and plucks/and the switch element of on-hook control circuit (19) is in cut-off state, disconnected being connected of dummy resistance and PSTN, made the PSTN be in hook state this user's telephone line; When CPU (16) output off-hook control signal (such as 1 level), pluck/switch element of on-hook control circuit (19) is in conducting state, connected being connected of dummy resistance and PSTN, made the PSTN be in off hook state this user's telephone line.During caller phone and PSTN keep being connected, excessive for avoiding PSTN to this telephone subscriber's load, should disconnect being connected of dummy resistance and PSTN.
The power circuit of Fig. 1 (22) provides the said device of the present invention (11) needed power supply, and this device required voltage is 5V and 48V/24V.The power source of power circuit (22) can be externally fed (such as 220 volts of alternating currents); When the power consumption of this device (11) is hanged down, also can obtain needed power supply from telephone wire from PSTN.
The task of the call signal tone detection circuit (23) of Fig. 1 is to detect the call signal sound (dialing tone, busy tone, ring-back tone) on the telephone line of PSTN end and judge whether the access phone of bypass route replys, its core circuit can adopt the generalized calls signal tone testing circuit of the M980/M981/M982 model of TELTONE company production, perhaps adopts the calling of the NE5900 model of PHILIPS Co.'s production to carry out decoder.Call signal tone detection circuit (23) converts the signal tone on the telephone line to pulse signal and gives CPU (16), because call signal tone detection circuit (23) mainly is band pass filter and level decision circuit etc., voice signal can be converted into pulse signal by this circuit too.According to relative national standards, the signal tone on the subscriber's line is:
Dialing tone: 450 ± 25Hz, continuously
Busy tone: 450 ± 25Hz sent/broke in 0.35 second in 0.35 second
Ring-back tone: 450 ± 25Hz sent/broke in 4 seconds in 1 second
Like this, CPU (16) just can be discerned the pulse signal of call signal tone detection circuit (23) output.Send the access telephone number to the bypass route after, signal on CPU (16) the identification telephone line, if it is not busy tone and ring-back tone, and signal can continue one time, judge that then it is a speech, confirm that promptly the access phone of bypass route is replied.
DTMF receiving circuit (17) among Fig. 1, DTMF transtation mission circuit (20) and call signal tone detection circuit (23) also can adopt the integrated circuit that has these functions simultaneously, the dual-tone multifrequency of the models such as M8880/M8888 that MT8880/MT8888/MT8889 that produces such as MITEL company or TELTONE company produce sends and receiver, these integrated circuits can provide complete DTMF to send and receiving function, have receiving calling signal sound and bandpass filtering function, and can with the microprocessor direct interface.
It will be appreciated that, device among Fig. 1 discussed above (11) only is an embodiment of the said method of the present invention, technical staff in the technical field of the invention is understood that, embodiment to Fig. 1 makes other embodiment that simple conversion just can obtain the said method of the present invention, such as reference Fig. 1, change DTMF receiving circuit (17) into the pulse dialing receiving circuit, perhaps change operation keyboard into and directly import called phone number (being fit to be applied to telephone set, facsimile machine etc.); Again such as reference Fig. 1, expanding many group DTMF receiving circuit (17), DTMF transtation mission circuit (20), call signal tone detection circuits (23), plucking/on-hook detection circuit (18), plucking/on-hook control circuit (19), after telephone wire control circuit (21) and the corresponding interface circuits, can use a CPU (16) to finish the calling redirection of router on multiple phone line road is handled.
Technical staff in the technical field of the invention is after fully understanding the said method and apparatus of the present invention, draw the present invention with being not difficult and can also be applied to the expect someone's call inside of terminal equipment of telephone set, facsimile machine, group telephone, subscriber exchange with the form of hardware module or software module, each element circuit of in this application, describing in the embodiment of the invention can to shared similar circuit and data in other module of equipment.
Because the present invention may and need be by finishing the phone of calling with each than the bypass route of low communication expense, all be redirected to automatically on the bypass route than the low communication expense, adding has a plurality of bypass routes than the low communication expense available simultaneously, increased the zone of calling by than low communication expense bypass route, thereby further reduced telephone charges usefulness, and can keep the custom called usually.
Also have, dial in the process of called phone number at caller phone, the present invention just can begin to be redirected to the operation of bypass route, add to adopt and in time judge the end of input of called phone number and initiatively discern bypass route access phone and technical measures such as whether reply, reduced the Call Waiting time than prior art.
Have again, because the present invention does not change the common mode of calling, therefore has more flexibility, it can be used as an independent device and is used between calling subscriber terminal and the PSTN, also it can be designed for the inside of telephone terminal, make it become a new function of telephone terminal.
