Description

A kind of voice over packet method

Technical field

The present invention relates to the communication technology, be specially a kind of speech communication method that adopts packet switching, more specifically say so a kind of can be with compatible with internet, the two-way mutual communication technology that is used to transmit real-time voice signal that can be used for the employing packet switching of unified public network of future generation, a kind of can be connection-oriented, also can be towards connectionless voice over packet method, the imagination that the present invention proposes be mainly used in the voice exchange based on packet switching, various switch router (core router or high-end switch router, edge or converge switch router, insert switch router), high/medium/low end Ethernet switch based on packet switch, multi-service transport platform (english abbreviation is MSTP), user side integrated access equipment (but incoming voice, data, the access device of any or several business in the video traffic) and any the interconnect equipment etc. relevant with packet voice.

Background technology

According to interrelated data, existing speech communication method has three kinds, is respectively:

(1) PSTN (PSTN is the english abbreviation of PSTN) phone;

(2) IP phone (IP is the english abbreviation of Internet Protocol);

(3) ATM (ATM is the english abbreviation of Asynchronous Transfer Mode, asynchronous transfer mode) packet voice tranmission techniques.

Wherein pstn telephone refers to the communication means that is used for transmitting voice service in the present telecommunications network, this is a kind of employing time-division multiplex technology and Circuit-switched connection-oriented speech tranmission techniques, this method is to transmit the main method of voice service at present in the world, its technology is the most ripe, most widely used general, history is the most remote, network size is the hugest, it is that people are for transmitting the custom-designed a kind of network technology of voice service, its main feature is to adopt connection-oriented technology, adopt time division multiplexing and circuit-switched technology, in order to realize the communication of both call sides, between both call sides, set up one by relevant signaling and connect link, for adopting time-multiplexed method, the utilance that improves communication line improves the efficiency of transmission of backbone network circuit, in order to guarantee that the realization conversation between different user connects, and adopts the circuit switching form to realize the exchange of different circuits.Though this method is a kind of technology of relatively optimizing for simple voice service, this technology also has some shortcomings and defective, as:

(1) line efficiency is low.Because it is a connection link of setting up a special use between both call sides, have only a side such as user A to have signal to be sent to an other side (being assumed to user B) during actual the conversation, this moment, user B was in idle condition to the circuit between user A, but this circuit still is in seizure condition.Actual in addition test shows, when even user A sends information (speech) to user B, the centre also also has a lot of times to be in no information state (promptly not speaking), user A has still taken whole circuit from A to B in these times, this telephone communication mode is like the automobile of running on expressway, if a car will be from certain place to the another one place, must keep two tracks to it so, a track of going direction, a track of returning, even this car in motion before and after circuit and to return the track be empty, (a certain moment, it only took certain space, front and back are empty certainly, the track that another one is returned also is empty) also will be for this car keeps the space, track, though this communication mode has service quality to guarantee, efficient obviously be poor efficiency (because front and back all are empty, can guarantee not can traffic congestion, but one road (track) can only run a car, the obvious poor efficiency of efficient), this poor efficiency communication mode must cause communications cost high.

(2) can not provide new business.Owing to this traditional voice communication network is merely for transmitting the special technology that voice service designs, on this network, be difficult to open up new business, along with the development of technology and user continuous enhancing to information requirements, the user wishes can obtain to comprise the various information of speech, data, video and multimedia whenever and wherever possible, can't satisfy this requirement of user to this traditional voice network.

(3) this employing time division multiplexing, circuit switching and connection-oriented speech tranmission techniques can not with unify the public network compatibility future.Generally believe now, following unified public network will be a kind of network that adopts packet switching, just why the whole world has stopped adopting the research and development of Circuit-switched telephone network technology for this, existing telephone network has the complete communication mechanism of a cover, comprise the telephone number addressing architecture, existing speech transmits network technology can not transit directly to unified public network of future generation.

(4) this speech tranmission techniques is dangerous, can not satisfy the demand of user to the fail safe of signal.Can be as those spiteful people by the phone of on subscriber's line, pegging graft, get final product careless free call on somebody else's expense through illegal means, also can at will eavesdrop the content of conversation, the user's communication content also has no safety guarantee, be easy to be eavesdropped, even conversation content has been eavesdropped, the user also knows nothing, and speech transmits in the way without any safety guarantee.

IP phone is a kind of speech communication method that adopts packet switching that produces along with the high speed development of internet, IP phone also is VoIP, and (VoIP is the english abbreviation of Voice over IP, the meaning is for transmitting speech on IP network), this method also has practical application at present in the world, the principle of IP phone is transmitting by IP network (mainly being IPv4) after the voice signal digitlization, its process is as follows: at first utilizing voice compression technique after the voice signal digitlization, then this signal bit (byte) is encapsulated into real time transport protocol (english abbreviation is RTP), again the Real-time Transport Protocol that has encapsulated voice signal is encapsulated into User Datagram Protoco (UDP) (english abbreviation is UDP), again UDP is encapsulated in the information field of IP agreement, in order on various physical networks, to transmit the IP bag that has encapsulated voice service, also must be again through the encapsulation process of various data link layer protocols, this speech transfer approach also comes with some shortcomings and defective:

(1) the processing level is many, complicated, expense is big, transmission efficiency is low.If the voice signal digitlization, and then adopt voice compression algorithm such as ITU-T G.729 signal to be compressed, every frame transmits the voice signal of 20 bytes, then voice signal being encapsulated into IPv4 need handle through the multi-protocols level of RTP/UDP/IP, the voice signal of 20 bytes only is encapsulated into data link layer, reach 47 bytes through above-mentioned encapsulation process overhead byte, expense is up to 47/67=70.1%.If adopt IPv6, expense will be bigger, if the expense of adding data link layer is then bigger, it is more to handle level, and technology is also just more complicated.

(2) there is not service quality to guarantee.Because IP network provides a kind of service of doing one's best, IP network does not have service quality to guarantee, for common data service, because its real-time is less demanding, IP network has a cover to guarantee to transmit the method for the correctness of data, for example suppose that a user will be sent to an other computer (being assumed to computer second) to a file from a computer (being assumed to the computer first) by file transfer protocol (FTP) (english abbreviation is FTP), second receives and reconfigures according to the numbering in the IP header behind all IP packets that first sends is a complete file, reconfiguring when being a complete file, if find mistake to occur then send to receive wrong indication, the indication transmit leg resends.For data, resending does not repeatedly have too big relation, but for voice service, because its real-time requires high, the repeating transmission that the user can not waiting signal not so can confusion reigned, be that independent process transmits owing to each IP wraps in the network in addition, the IP bag that might the back sends arrives first, back the arriving of sending out earlier, and it doesn't matter to the IP bag for this situation, but then dying to voice service, word arrives first because this may cause the back, arrives behind the first word, and this consequence is well imagined.

(3) owing to IP handles by the routing forwarding of IP address realization IP bag, and common phone utilizes the telephone number connection that realizes conversing, therefore when utilizing IP to transmit speech, must realize the mapping of telephone number to the IP address, this has increased the processing level on the one hand, and the another one shortcoming is the in short supply of IP address.What present IP network adopted is IPv4 (i.e. the Internet Protocol of the 4th version), IPv4 adopts the address of 32 bits, 232 addresses can be arranged in principle, tens addresses promptly can be arranged, but because IPv4 is divided into the IP address 5 class addresses such as A, B, C, D, E, actual available IP address much less, this makes the IP address very nervous.If use IPv6, can change the situation of IPv4 address shortage, but IPv6 and IPv4 are incompatible, adopt IPv6 like this or all, but a huge network has been built in the whole world aspect IPv4 now, though have tunnel protocol can realize the transmission of IPv6 on the IPv4 network, the in fact most IPv4 network equipment is not supported this function, therefore at present IPv6 and the IPv4 intercommunication of having no idea.

(4) lack security mechanism.As everyone knows, existing IP network is without any safety, and IP bag itself can be modified, its content can be stolen, duplicates, change, if the content need to be keep secret of user's communication like this, existing IP network can not meet the demands, and user's information has no safety.If user's communication speech need to be keep secret, (IPsec is that (IETF is the standards body of internet to the internet engineering task group IETF of Internet Standard mechanism can only to adopt IPsec, be the english abbreviation of internet engineering task group) a kind of IP security mechanism of formulating), increased expense so on the one hand more, on the one hand increased the processing level in addition, and carried out encryption itself and need the time may cause being difficult to more satisfy the real-time requirement of voice service.

(5) present networks does not have the network protection switch function; 50 milliseconds of switch functions particularly; this function is absolutely necessary for voice service; in case switch and refer to network and break down for 50 milliseconds; break down as circuit or equipment; require so in 50 milliseconds time, the circuit of conversation to be switched on the in addition normal circuit from faulty line; if in 50 milliseconds of times, realized this function; the interruption of the imperceptible conversation of user; because what IP adopted is the 3rd layer of exchange; in several seconds, this obviously can not meet the demands the switching time of IP network at the soonest at present.

(6) present networks adopts two class Routing Protocols (class is an Interior Gateway Protocol, an other class is an Exterior Gateway Protocol) realize that the forwarding of IP bag handles, rely on existing Routing Protocol to realize that the forwarding of IP bag does not have the traffic engineering ability, even this may cause having between two nodes many and connect the transmission that link can be realized packet, but router relies on Routing Protocol all to be forwarded to the IP bag on the link, thereby it is congested to cause this link to produce, and this moment, other link was in idle condition, caused losing of voice signal thereby produce packet loss.

(7) existing telephone network has the complete communication plan of a cover, built up a whole network system through 100 years of development, if traditional telephone network is added on the IP network simply, whole technique implements very complicated so, and actual proof, because IP network does not have service quality to guarantee, the telephone network that superposes simply on IP network realizes that it is infeasible that the grouping of voice service transmits, this load mode does not have service quality to guarantee, fact proved, only rely on existing IP technical deficiency to construct unified carrier class public network of future generation.

Adopt ATM to transmit the method for speech as for the third, it is a kind of speech tranmission techniques of atm forum design, it advocates voice service is transmitted by atm technology, method is at first by ATM Adaptation Layer (ATM first kind adaptation layer protocol, the ATM second class adaptation layer protocol), and then by ATM layer transmission speech, ITU-T also supports ATM, but because ATM is a kind of technology of a kind of technology driving rather than market-driven, be a kind ofly can unify all professional a kind of technology that promptly are referred to as integrated digital network and design in order to design, initial this technology imagination all adopts ATM to realize the transmission of all business from the user terminal to the core network, is called ATM Adaptation Layer (english abbreviation is AAL) by interpolation one deck on the ATM layer and realizes the adaptive of all business.ATM adopts packet design, and each ATM frame length is 53 bytes, and wherein atm header is 5 bytes, and payload is 48 bytes like this.Because the design and the market demand of ATM seriously disconnect, add and its technology imagine too perfection to cause technology to implement very complicated, delay to realize standardization, thereby delay large-scale application, add surfed the Internet since the nineties in last century flourish, whether support technique of internet to become and weigh the key factor whether a kind of communication technology has vitality, ATM will develop must support internet service, yet, because the internet is a kind of elongated Packet Service, and ATM is a kind of fixed length packet technology, ATM expense all too when transmitting IP operation is big, unexpectedly reach about 25%, efficiency of transmission is extremely low.Progressively become the main flow business of future network along with IP operation, add owing to atm device costliness, technical sophistication, can not support the speed that 10Gbps is above, ATM progressively becomes a kind of superseded technology like this, therefore utilize ATM to transmit voice service and never obtain large-scale application, the target of unifying whole network with ATM is impossible, realizes that with ATM the transmission of packet voice also just becomes a kind of technology that can not use.Atm technology itself is tending towards superseded now, and some correct ideas that is this technology can exist in unified from now on public network.

No matter compare existing speech tranmission techniques, be to traditional employing time division multiplexing, circuit switching and connection-oriented speech tranmission techniques or novel IP phone the present invention has carried out a series of innovation, specific as follows:

Adopt time division multiplexing with respect to having now, following innovation arranged towards connection and the present invention of Circuit-switched speech tranmission techniques:

(1) line efficiency height.In the existing P STN phone since it be the connection link of between both call sides, setting up a special use, have only a side such as user A to have signal to be sent to an other side (being assumed to user B) during actual the conversation, this moment, user B was in idle condition to the circuit between user A, but this circuit still is in seizure condition, actual in addition test shows, when even user A sends information (speech) to user B, the centre also also has a lot of times to be in no information state (promptly not speaking), user A has still taken whole circuit from A to B in these times, this telephone communication mode is like the automobile of running on expressway, if a car will be from certain place to the another one place, must keep two tracks to it so, a track of going direction, a track of returning, even this car in motion before and after circuit and to return the track be empty, (a certain moment, it only took certain space, front and back are empty certainly, the track that another one is returned also is empty) also to keep the space, track for this car, though this communication mode has service quality to guarantee, but efficient obviously is that poor efficiency is (because front and back all are empty, can guarantee not can traffic congestion, but one road (track) can only run a car, the obvious poor efficiency of efficient), this poor efficiency communication mode must cause communications cost high.And adopt method provided by the invention, because what the present invention adopted is packet-switch technology, what adopt is the classified statistics multiplex techniques, between both call sides, only set up a logical links rather than actual circuit, thereby improved line efficiency greatly, if one side such as user A have signal to be sent to an other side (being assumed to user B) during the actual conversation of user, this moment, user B was in idle condition to the circuit between user A, but this circuit is not to be in seizure condition but to use to others, this telephone communication mode is like the traveling automobile on the present highway, if this car will be from certain place to the another one place, the space uses for other vehicle before and after so during its actual travel, use to others especially as for the track of returning, the great like this utilance that improves circuit, as not occurring traffic congestion on the highway in order to guarantee, need control the flow of vehicle, the present invention also provides the traffic engineering ability, the cost of network can be reduced so greatly, also the user's communications expense can be reduced simultaneously.

(2) can provide new business for the user.Existing P STN phone is owing to being the special technology that designs for the transmission voice service merely, on this network, be difficult to open up new business, along with the development of technology and user continuous enhancing to information requirements, the user wishes can obtain to comprise the various information of speech, data, video and multimedia whenever and wherever possible, can't satisfy this requirement of user to this traditional voice network.And adopt method provided by the invention, what adopt is the grouping tranmission techniques, and can with the compatibility of internet, on same network, not only can provide simple voice service, visual telephone service also can be provided, Video service is provided, the various data services that comprise multimedia also can be provided, promptly on a network, can realize the transmission of full-service, can satisfy the user and obtain to comprise any information that he wants such as speech, data, video and multimedia messages whenever and wherever possible.

(3) be smoothly transitted into following unified public network on the basis of reservation existing telephone transmission network elite.What existing P STN telephony adopted is time division multiplexing, circuit switching and connection-oriented speech tranmission techniques, this technology can not with unify the public network compatibility future of adopting packet-switch technology, this speech transmits network technology can not transit directly to unified public network of future generation.And adopt method provided by the invention; what adopt is packet-switch technology; some elite of existing telephone network such as telephone number resource etc. have been kept; by existing telephone network being carried out minor modifications the existing telephone network is smoothly transitted on the unified public network of future generation; realize that existing telephone network is smoothly transitted into unified public network of future generation; can protect existing investment; and can utilize existing telephone number resource; the user utilizes an existing number can obtain to comprise speech; data; video is in interior whole business, thereby need not to use IP address in short supply.

(4) provide powerful security performance for the speech tranmission techniques.Existing P STN telephony is dangerous, can not satisfy the demand of user to the fail safe of signal, can be as those spiteful people by the phone of on subscriber's line, pegging graft, get final product careless free call on somebody else's expense through illegal means, also can at will eavesdrop the content of conversation, the user's communication content also has no safety guarantee, be easy to be eavesdropped, even conversation content has been eavesdropped, the user also knows nothing, and speech transmits in the way without any safety guarantee.And adopt voice over packet method provided by the invention that powerful safety function is provided, the invention provides three kinds of security mechanisms, the one, in network,, on the transmission lines of speech, be difficult to discern user's real identity like this with a temporary designator replacement user's true number; Two provide a kind of authenticating user identification mechanism, need carry out authentication through network authentication administrative center when the user makes a phone call, and have avoided the possibility of fake user identity in the traditional voice communication; Three have provided and a kind of signal have been authenticated mechanism with encryption, and it is irrelevant with concrete algorithm, Virtual network operator promptly can adopt common crypto algorithm such as AES (AES is the new encryption standard that the U.S. is used to replace the original cryptographic algorithm standard DES that uses), DES, also can adopt special-purpose encryption algorithm (as the military encryption algorithm of special use) according to special requirement, if, can change algorithm at once in case find that the enemy may crack password.Making like this becomes impossiblely by the careless free call on somebody else's expense through illegal means of phone of pegging graft on subscriber's line, and the content of user's communication is not easy to be eavesdropped, and this technology is particularly suitable for diplomacy, the military communication field of safety requirements.

Compare with existing IP phone, the present invention has the following advantages:

(1) processing is simple, expense is little.Present IP phone need be earlier voice signal being encapsulated into real time transport protocol when transmitting speech, and then be encapsulated into User Datagram Protoco (UDP), be encapsulated into again in the IP bag, again IP is sealed at last and install to data link layer protocol, data link layer protocol may also not be a kind of in practice, only the voice signal after the digitlization is encapsulated into data link layer, reach 47 bytes through above-mentioned encapsulation process overhead byte, if adopt IPv6 only the IP header expense of 40 bytes is just arranged, add that the expense of link layer header is then bigger.Because packet voice transfer approach provided by the invention need not to handle through IP, directly voice signal is encapsulated into data link layer, and has only the data link layer protocol of one deck, and handle simply the great like this network overhead that reduced.

(2) there is service quality to guarantee.Because IP network provides a kind of service of doing one's best, IP network does not have service quality to guarantee, so IP phone does not have service quality to guarantee, guarantee speek voice quality, just must guarantee bandwidth, and in fact spendable bandwidth may satisfy user's demand never, the relation object of this and automobile and road seemingly, the growth rate of road width of roadway can not surpass the growth rate of automobile quantity, otherwise traffic congestion can only tube be managed as flow is carried out limitation management.For guaranteeing the service quality of speech, the invention provides multiple assurance mechanism, one of them is to the miscellaneous service processing of classifying, business is divided into the high real time business of quality of service requirement (having comprised voice service) and unessential non-real-time service such as common IP operation two big classes, and be defined in priority treatment forwarding real time business when handling, when can not meeting the demands, network at first abandons the IP operation bag to guarantee the transmission of this important real time business of speech; Another is to the invention provides the traffic engineering ability, utilize traffic engineering can dredge the flow of network, as being appointed as the transmission real time business for some particular link, some link is appointed as and is transmitted less demanding business such as IP operation, and those links that transmit real time business only allow to transmit a certain amount of data, in case the real time business link breaks down, interrupt the transmission of non-real-time service such as common IP operation immediately, give real time business these link assignment.

(3) can utilize the number resource of existing telephone, need not to use the IP address.Because IP is the routing forwarding processing that realizes the IP bag by IP address (mainly being purpose IP address), and phone is realized conversing by telephone number, therefore when transmitting speech with IP, must realize the mapping of telephone number to the IP address, if it is plain old telephone that a side is arranged, one side is a computer, and so once conversation need be carried out twice mapping processing.If both sides are plain old telephones, providing IP to transmit speech then needs 4 mappings to handle, implement complexity like this, and because present IP network adopts is IPv4, IPv4 adopts the address of 32 bits, 232 addresses can be arranged in principle, tens addresses promptly can be arranged, but because IPv4 is divided into A to the IP address, B, C, D, 5 class addresses such as E, actual available IP address much less, this makes the IP address very in short supply, therefore the address anxiety of IP phone can be used for,, IP address problem in short supply can be solved if IP adopts IPv6, but crucial problem is that IPv6 and IPv4 are incompatible, and the present IP network equipment overwhelming majority is not supported IPv6.And adopt the present invention to transmit speech, need not the IP address, directly can use existing telephone number resource, only need have the network authentication center to specify an address code (destination address sign indicating number or source address sign indicating number) to the user, need not complicated telephone number to the IP address, the IP address is to the mapping processing of telephone number.

(4) provide multiple security mechanism to ensure the safety of Speech Communication.As everyone knows, present networks is without any safety, itself can be modified the IP bag, its content can be stolen, duplicate, if user's conversation need to be keep secret like this, common IP phone can not meet the demands, if guarantee the safety of IP phone, must use a kind of security mechanism IPsec as (a kind of IP security mechanism that IPsec formulates as the internet engineering task group IETF of Internet Standard mechanism), so on the one hand more XXL processing expenditure, need the time (particularly handling) and may cause being difficult to more satisfy the real-time requirement of voice service owing to carry out encryption on the one hand in addition with software.And the present invention can provide reliable safety guarantee for voiceband user, the invention provides three kinds of security mechanisms, the one, in network,, on the transmission lines of speech, be difficult to discern user's real identity like this with a temporary designator replacement user's true number; Two provide a kind of authenticating user identification mechanism, need carry out authentication through network authentication administrative center when the user makes a phone call, and have avoided the possibility of fake user identity in the IP phone; Three have provided and a kind of signal have been authenticated mechanism with encryption, and it is irrelevant with concrete algorithm, Virtual network operator promptly can adopt common crypto algorithm such as AES (AES is the new encryption standard that the U.S. is used to replace the original cryptographic algorithm standard DES that uses), DES, also can adopt special-purpose encryption algorithm (as the military encryption algorithm of special use) according to special requirement, if, can change algorithm and password at once in case find that the enemy may crack password.

(5) provide the network protection switch function, can realize 50 milliseconds of switch functions of network failure.In case 50 milliseconds of protections are switched and are referred to network and break down; break down as circuit or equipment; require so in 50 milliseconds time, the circuit of conversation to be switched on the in addition normal circuit from faulty line; if in 50 milliseconds of times, realized this function, the interruption of the imperceptible conversation of user.Present networks is not protected switch function; because what IP network adopted is three layers of route; the realization three-layer network protection switch time of IP network is approximately several seconds now; 50 milliseconds of protections in this and the Speech Communication switch that to require gap to differ all too big; if therefore link fails may cause the interruption of IP phone, thereby can not satisfy the real-time requirement of voice service.And the present invention provides 50 milliseconds of wrap protections on data link layer, adopts the present invention can realize that 50 milliseconds of protections of network switch, and guarantees the real-time requirement of voice service.

(6) provide the traffic engineering ability.Present networks adopts two class Routing Protocols, and (class is an Interior Gateway Protocol, an other class is an Exterior Gateway Protocol) realize that the forwarding of IP bag handles, rely on existing Routing Protocol to realize that the forwarding of IP bag is not have the traffic engineering ability, even this may cause having between two nodes many to connect link, but router relies on Routing Protocol all to be forwarded to the IP bag on the link, it is congested to cause this link to produce, and other link is in idle condition, cause losing of voice signal thereby produce packet loss, can not satisfy the requirement of voice service.And the invention provides the traffic engineering ability, and can carry out dynamic management to the flow of whole network, make whole network link equilibrium, can not produce some link idle, and other link congestion causes packet loss, thereby satisfy the requirement that real-time speech transmits.

(7) can realize the fusion of existing telephone network and IP network, make existing telephone network and IP network be smoothly transitted into unified public network of future generation.Existing telephone network gets up through 100 years of development, has built up a whole network system now, has formed the complete communication plan of a cover.And IP network is a network that grows up nearest decades, whether and the IP network technology unify will occupy crucial status in the public network in future, support IP operation to become and estimate the important indicator whether a kind of network technology has permanent vitality.But telephone network is two different networks with IP network after all, no matter is technology itself, or network requirement all has very big difference.If on the simple IP network that telephone network is added to, whole technique will be very complicated so on the one hand, and actual proof, because IP network does not have service quality to guarantee, telephone network of stack realizes that the transmission of voice service is infeasible on IP network.On the other hand, this network may be to get the short length of mending, and whole network becomes David's deer, and what cause network using is the shortcoming of two kinds of networks, and does not use both advantages.In addition, from there is some evidence, rely on present networks also to be not enough to constitute unified public network of future generation merely.And adopt the present invention can realize the fusion of telephone network and IP network, double advantage of getting two kinds of networks, reject both shortcomings again, and not only can realize the fusion of telephone network and existing IPv4 network, also can realize telephone network and the fusion of IPv6 network in the future, and can realize the fusion of IPv4 and IPv6 network.

(8) need not the requirement that user multi-service communication can be realized in the IP address.Though IP network can provide all business that comprise speech, data and video, but because existing telephone network is only supported voice service, the IP video telephone can only realize that the multi-service that guarantees even without service quality is irrealizable at computer and intercomputer on present IP phone.And adopting the present invention can need not the multi-service communicating requirement that a number is realized in the IP address, the user can provide speech, data and video traffic on a network.
