Description
Technical field
The present invention relates to the communication equipment in the Internet, the public telephone network, relate in particular to a kind of survival equipment and method thereof with escaping function.
Background technology
Along with development of Communication Technique, the computer network bandwidth constantly increases, and speech data can be carried on the Internet (hereinafter will abbreviate IP network as).VoIP (Voice over IP) is the networking telephone, is the emphasis business of NGN (next generation network), and it has promoted network resource usage, has reduced the speech business cost.In order to reduce cost of the phone call, increasing user begins to select to carry out voice call by voip network.
Fig. 1 is the permission data of prior art and the application schematic diagram of the communication equipment 100 that voice send to IP network.As shown in Figure 1, computer and ordinary telephone set are connected on the IP network via Ethernet/adsl line by communication equipment 100.Communication equipment 100 comprises interconnective CPU module and speech processing module.
Computer sends to the CPU module with digital signal, and the CPU module sends to IP network by Ethernet/adsl line with these IP data after the Digital Signal Processing that receives is the IP data, by IP network these IP data is sent to destination.Ordinary telephone set sends to speech processing module with voice signal, by speech processing module the voice signal that receives is carried out processing such as mould/number conversion, compressed encoding, and obtain the discernible data of CPU module, and send to the CPU module, be to send to IP network after the IP data by the CPU module with the language data process that receives again, these IP data sent to destination by IP network.Like this, just can send voice signal, make the user both can reduce cost of the phone call, not influence data services such as normal computer internet again by the IP network service.
Computer only is an example of digital device, but digital device is not limited thereto.The digital device of indication is meant that the signal that sends and receive all is the equipment of the signal of digital form among the application.Common program controlled telephone only is an example of speech ciphering equipment, but speech ciphering equipment is not limited thereto, and for example can also be fax.The speech ciphering equipment of the application's indication is meant that the signal that sends and receive is the equipment of the voice signal of analog form.Here, communication equipment 100 is a kind of access devices, for example can be computer, gateway and router etc.Ethernet/ADSL only is the example that communication equipment is connected to IP network, but be not limited thereto, communication equipment can also be connected to IP network by SHDSL (symmetrical high-bit-rate digital subscriber line), VDSL2 (ultrahigh speed number of users word line), Cable Modem (cable modem), GPON (a kind of PON agreement).
Under normal circumstances, communication equipment 100 can transmit speech data and numerical data.Yet, IP network is unreliable service, it is not the circuit that the user exclusively enjoys, if the user who uses is many, perhaps computer network virus causes network paralysis, and other unpredictable factor is when causing network to use, if the user has urgent phone, fax, when perhaps having the important electron mail to send, communication equipment 100 just can not be right.
At present, developed and a kind of data escape can when IP network is unavailable, carried out, and the survival equipment that when for example breaking out of fire of even worse situation, typhoon or the like factor causes power failure, carries out the voice escape, it has utilized reliability will be higher than the public telephone network (hereinafter will abbreviate the PSTN network as) of IP network.Here, escape is meant that (electricity is arranged survival equipment but IP network is unavailable and survival equipment does not have) backs up data business and speech business under improper situation.
Fig. 2 is the application schematic diagram of survival equipment 200.For brevity, the part that Fig. 2 is identical with Fig. 1 repeats no more, and only describes their different piece.
As shown in Figure 2, survival equipment 200 is connected on two PSTN networks by two telephone wires, promptly on PSTN network 1 and the PSTN network 2.Except comprising interconnective CPU module and speech processing module, also comprise in the survival equipment 200: modem module (hereinafter referred Modem module), it is connected to the CPU module, and is connected to PSTN network 1 by a telephone wire; The escape commutation circuit, it is connected to speech processing module and speech ciphering equipment respectively; The escape interface, it is connected to the escape commutation circuit.
At survival equipment 200 but electricity and IP network time spent are arranged, the operation of the survival equipment 200 among Fig. 2 is identical with Fig. 1.Only describe survival equipment 200 below still unavailable the and electric situation of survival equipment 200 nothings of IP network of electricity is arranged.
When survival equipment 200 has, when but IP network is unavailable, computer sends to digital signal by Ethernet the CPU module of survival equipment 200, the CPU module judges whether IP network is available, when finding that IP network is unavailable, then this digital signal is sent to the Modem module, by this Modem module this digital signal is converted to analog signal, send to destination by PSTN network 1, for example on the IP network that far-end can be used.The escape of this data is mainly used in the situation that local network that survival equipment 200 connected or local area network (LAN) break down, and at this moment can dial up on the telephone by the Modem module, promptly is connected on the operable IP network of far-end by PSTN network 1.At this moment, can surf the Net transmitting-receiving Email with low rate.
If worse off, i.e. during survival equipment 200 outages (may be could not get on to the Net this moment), the escape commutation circuit disconnects speech processing module from speech ciphering equipment, and speech ciphering equipment is directly connected to the escape interface, and then is connected to PSTN network 2.Like this, voice signal sends to PSTN network 2 by the escape interface, by PSTN network 2 this voice signal is sent to called end.Because under the situation that survival equipment 200 has a power failure, telephone set has been directly connected to the escape interface, make under the situation that the fugitive generating apparatus 200 of user has a power failure, can normally use phone, especially dial emergency calls such as 119,110.
Fig. 3 is the exemplary circuit diagram of the escape commutation circuit of survival equipment 200 among Fig. 2.As shown in Figure 3, the escape commutation circuit comprises a dpdt relay.When survival equipment 200 had electricity, speech ciphering equipment interface and speech processing module were connected, and when survival equipment 200 had a power failure, the speech ciphering equipment interface was connected with the escape interface.
But survival equipment 200 still has shortcoming, and is mainly as follows:
1. if the user needs the function of voice escape and data escape simultaneously, just must rent two telephone wires (port in the PSTN network), the monthly rent cost is higher, for the consideration that reduces cost, most of users only rent a subscriber's line, so just can only carry out voice escape or data escape.
2. must could between voice escape and data escape, switch by cutting off the electricity supply.Particularly, under the situation that electricity is arranged, can not carry out the voice escape, carry out the voice escape if desired, must cut off the power supply of survival equipment 200.Because survival equipment 200 is placed in the machine room usually, cut off the electricity supply, it is very inconvenient to restart power supply.Because data escapes can only be carried out under the situation that electricity is arranged, therefore, after the voice escape disposes,, also must power on to survival equipment 200 if carry out data escapes (as send Email), just can carry out after just restarting survival equipment 200.
3. do not allow a telephone wire both can carry out data escapes, can carry out the voice escape again, and the automatic switchover that data escape and voice are escaped when not supporting electricity.

After the CPU module receives data from digital device, if it is unavailable to detect IP network, just send control signal, the switch of control relay 20 switches to the below, thereby the Modem module is connected with the escape interface, for dialling up on the telephone by the Modem module, be and carry out data escapes and created condition, and the switch of relay 10 state that still keeps up.
Here with relay as the escape commutation circuit example, but the escape commutation circuit be not limited to relay, can also adopt other switching device that can realize this handoff functionality.
The first embodiment of the present invention has realized that the data escape no longer needs to rent separately a telephone wire, thereby rents the survival equipment that a telephone wire just can carry out data escape and voice escape.And the circuit connection structure of survival equipment 300 is not only simple, and has simplified the framework that is connected with the PSTN network in the external world, has reduced the maintenance cost and the customer using cost of PSTN network.
The survival equipment 400 of the second embodiment of the present invention is described below in conjunction with Fig. 6.The second embodiment of the present invention is the improvement embodiment of first embodiment, it only need not rent a telephone wire just can carry out data escape and voice escape, and allow electricity to be arranged when but IP network is unavailable, need not cuts off the electricity supply and just can carry out the voice for example placement of emergency calls of escaping at survival equipment.Those skilled in the art can understand the scheme of not cutting off the electricity supply and can automatically switch of renting two telephone wires easily by first above-mentioned embodiment and the second following embodiment between voice escape and data escape, therefore repeat no more here.
Fig. 6 is the application schematic diagram according to the survival equipment 400 of second embodiment of the invention.What survival equipment 400 and survival equipment 300 were different is: after speech processing module can also decompress the data of returning from the CPU module, decoding, D/A switch etc. handle, be reduced into voice signal, and send to the escape commutation circuit; When the escape commutation circuit also is used for having electricity and IP network unavailable in system, make escape interface and speech processing module connection, this point sees also hereinafter the description to Fig. 7.
Therefore, electricity is arranged but IP network when unavailable at survival equipment 400, the CPU module will turn back to speech processing module from the speech data that speech processing module receives, transmit control signal to the escape commutation circuit simultaneously, the PSTN network is connected and then be connected to the control speech processing module with the escape interface, thereby allow the voice escape.
The second embodiment of the present invention has realized that voice escapes needn't one fixes under the powering-off state and has carried out.Therefore, can when survival equipment 400 has electricity, carry out the voice escape, thereby after the voice escape disposes, not need to restart power supply and just can then carry out data escapes (as send Email), convenient for users to use.
Fig. 7 is the exemplary circuit schematic of survival equipment 400.
As shown in Figure 7, speech processing module comprises: analog subscriber interface (hereinafter will abbreviate the FXS interface as) is used to be connected to described speech ciphering equipment; Analog Trunk Interface (hereinafter will abbreviate the FXO interface as) is used to be connected to the escape interface, and then is connected to the PSTN network; And digital signal processing device (hereinafter referred is DSP), be connected to FXS interface and FXO interface, be used for and carry out through the voice signal that the FXS interface receives obtaining the discernible digital speech of CPU module after the processing such as mould/number conversion, compressed encoding, and send it to the CPU module, and will decompress from the data that the CPU module is returned, after decoding, D/A switch etc. handle, be reduced into voice signal, and be sent to the PSTN network through FXO interface, escape interface.
Control circuit is used for the change action according to the control signal control escape commutation circuit of CPU module.In Fig. 7, control circuit is placed on the CPU module, can be the generic logic device, also can be programmable logic device.But control circuit also can be the general pin of CPU, and promptly CPU is by programming, and general pin that can Controlled CPU is a high-low level.These high-low levels can be directly connected on the relay among Fig. 5, Fig. 9, because the relay of Fig. 5, Fig. 9 is a commutator, only need two kinds of level of height just passable.Sometimes for higher reliability, can control triode by high-low level, and then the control pin on the control relay, can reach good level match.Three throw switches of Fig. 8 just need three kinds of level, can realize by the logic control triode.Those skilled in the art should be appreciated that this specification appended claims by above-mentioned disclosure control device by the control device on the ordinary meaning for example the CPU module of prior art add that control circuit of the present invention forms, or after for example the CPU module of prior art is programmed to the control device on the ordinary meaning, obtain.
The escape commutation circuit can be the switch of relay or other types, be used for carrying out various change actions according to the control signal of power-down state and control device, finishing following four kinds of circuit connects: speech ciphering equipment and escape interface are connected the voice escape when being used for power down; Speech ciphering equipment and speech processing module are connected, and the interface of will escaping is vacant, is used for normal condition; Speech ciphering equipment and speech processing module are connected, and speech processing module and escape interface are connected, the voice escape when being used to electricity is arranged; Speech ciphering equipment and speech processing module are connected, and Modem module and escape interface are connected, the data escape when being used to electricity is arranged.
As seen, the interface in the survival equipment 400 comprises: telephone line interface, escape interface, FXS interface, FXO interface, Modem analog circuit interface.Survival equipment 400 is described below specifically
Points for attention in the enforcement:
Interface switches and must guarantee: any two all can not connect together the isolation that must remain valid in FXS interface, FXO interface, the Modem analog circuit interface.
Telephone line interface can only connect in the interface one of FXS interface and escape, only otherwise be in power down escape state, just is connected to the FXS interface always.
The escape interface can only connect in FXO interface, Modem interface, the telephone line interface.
When the escape interface connected the FXO interface, telephone line interface must be connected to the FXS interface.
During the system power down, telephone line interface must be connected to the escape interface.
Fig. 8 is the exemplary circuit diagram of the escape commutation circuit in the survival equipment 400.
As shown in Figure 8, this escape commutation circuit comprises relay 11, relay 22.Wherein, relay 11 and relay 22 can be same models, also can be different models.In order to make device normalization, make relay 11 and relay 22 all adopt the SP3T switch to form at present embodiment.Wherein, relay 11 also can use the veneer commutator.
When survival equipment 400 did not power on, the switch of relay 11, relay 22 all was in the intermediate contact position, thereby speech ciphering equipment is connected directly to the escape interface, the voice escape state when be power down this moment.
When survival equipment 400 powers on, under the control of CPU module, the switch of relay 11 switches to the top, thereby speech ciphering equipment and speech processing module are connected, and then allow to send data to the CPU module through speech processing module from speech ciphering equipment, and the switch of relay 22 still keeps intermediateness, thereby the escape interface is vacant.
After the CPU module receives data from digital device, if it is unavailable to detect IP network, just send control signal, the switch of control relay 22 switches to the below, thereby the Modem module is connected with the escape interface, for dialling up on the telephone by the Modem module, be and carry out data escapes and created condition, and the switch of relay 11 state that still keeps up.
After the CPU module receives data from speech ciphering equipment, if it is unavailable to detect IP network, just send control signal, the switch of control relay 22 switches to the top, thereby the FXS interface is connected with the escape interface, and the switch of relay 11 state that still keeps up, thereby created condition (state shown in Figure 8 belongs to this situation) for carrying out the voice escape.
Fig. 9 is another exemplary circuit diagram of the escape commutation circuit in the survival equipment 400;
As shown in Figure 9, this escape commutation circuit comprises relay 111, relay 222 and relay 333.In this example, relay 111, relay 222 and relay 333 are three double-point double-throw switchs.Those skilled in the art is by reading Fig. 9, the escape commutation circuit that is appreciated that the escape commutation circuit of this example and Fig. 8 fully is similar, can finish four kinds of circuit and connect (state shown in Figure 9 belongs to that survival equipment has electricity but circuit under the voice escape situation of IP network when unavailable connects), therefore repeat no more here.
Figure 10 is the flow chart that escape method of the present invention combines with priority policy.
Normally in service at survival equipment according to the present invention, both can surf the Net, can dial voip phone again.But when upstream Interface Ethernet or ADSL etc. cannot use owing to various unpredictable reasons, the data service of computer can be by the CPU module forwards to the Modem module, while CPU control relay 20 (Fig. 5), perhaps relay 22 (Fig. 8), perhaps relay 222 and 333 (Fig. 9) makes the Modem module be connected to the escape interface.Plain old telephone service and facsimile service are linked into the FXS interface by telephone line interface, through sending to the CPU module after the DSP processing, the CPU module finds that up Ethernet or ADSL etc. can not use, telephone service or facsimile service are sent to the DSP of speech processing module and then be sent to the FXO interface, while CPU module controls relay 22 (Fig. 8), perhaps relay 222 and 333 (Fig. 9) makes the FXO interface be connected to the escape interface.
Owing to have speech business, facsimile service, data service, and also comprise the difference of plain old telephone service and placement of emergency calls in the speech business, miscellaneous service is shared same escape interface, must distinguish priority, distinguish the rule of priority: emergency call is a limit priority, and fax, Email, plain old telephone are high medium priority, and surfing the Net is lowest priority, can certainly adjust priority orders according to user's demand.
For example, the priority of placement of emergency calls (as 119,120) is made as limit priority, i.e. priority 1, fax, Email, plain old telephone are made as priority 2, are minimum n with the priority of user's online, and at this moment, the total number of levels of service priority is n.When the CPU module is received the data of sending the outside, as new interrupt requests, after the CPU module receives interrupt requests, judge whether IP network is available, if IP network can be used, then carry out normal process, data are sent to IP network.Otherwise, when the CPU module finds that IP network is unavailable, judge whether the service priority of the data that receive is 1.If the service priority of the data that receive is 1, then stop the current low priority traffic of handling, handle this priority and be 1 business, the phone escape when electricity is arranged (claiming the voice escape again).
If the service priority of the data that receive is not 1, the CPU module judges then whether the service priority of the data that receive is 2.If the service priority of the data that receive is 2, judge then whether the current service priority of handling is greater than or equal to 2.If the current service priority of handling is greater than or equal to 2, for example, the interrupt requests that receives is a plain old telephone, and the current business of handling is a send Email, the priority of the two is identical, then continue to handle the current business of handling, promptly continue send Email, the data escape when electricity is arranged.Otherwise, stopping to handle the current business of handling, first processing priority is 2 business.Judge successively, till judging whether the current service priority of handling is greater than or equal to n (the total number of levels of service priority).So just can realize the optimal treatment of escaping.
Further, in Fig. 6, can connect a plurality of speech ciphering equipments (ordinary telephone set or facsimile machine), therefore a plurality of telephone line interfaces are arranged, thereby speech processing module have a plurality of FXS interfaces.According to above principle, the escape commutation circuit increases corresponding switch telephone line interface all is connected on the corresponding FXS interface, software processed even can control the priority of each telephone set or fax or the priority of each telephone number.
Priority policy shown in Figure 10 is exactly in brief: described control device is down judged successively from limit priority, except when the service priority of judging the current data that receive is limit priority, stopping the current low priority traffic of handling immediately, handle the business that this priority is limit priority, when being other priority professional for judged result, whether the priority of then judging the current business of handling is higher than the service priority that equals the current data that receive, if be higher than the service priority that equals the current data that receive, then continue to handle the current business of handling; Otherwise, stop to handle the current business of handling, handle the current data that receive earlier.But the invention is not restricted to this, connect the multi-section speech ciphering equipment for example when multi-section phone and fax at survival equipment of the present invention, just might receive service priority is a plurality of emergency calls of limit priority, also can directly not interrupt business this moment when pre-treatment, but judge whether the priority of the current business of handling is higher than the service priority that equals the current data that receive earlier, if be higher than the service priority that equals the current data that receive, then continue to handle the current business of handling, otherwise, then handle the business that this priority is limit priority.
For priority policy is applied to the present invention, need storage from the professional of digital device and from the storage device of the service priority of the business of described speech ciphering equipment.This storage device can be arranged on the control device outside, is connected with control device, also can be arranged on control device inside, as long as control device can read the service priority data when needing from this storage device.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
