Abstract
A by-pass method for the dialing access service of internet features that the call processing software of exchanger is used to determine that current stream sent by user is data service stream or audio service stream, and if it is data service stream, it is by-passed from PSTN network to internet. Its advantages are no need of changing the structure of existing telecommunication network as the said function is implemented in exchanger, and no congestion of telecommunication network.
Description
The present invention relates to a kind of method that realizes internet Internet (following general designation Internet) dialing access service bypass, relate in particular to a kind of method that adopts the inboard bypass technology of switch to realize internet dialing access service bypass.
At present, the main means that the user inserts Internet are the dial-up accesses by voice band Modem and Integrated Service Digital Network ISDN, and just these dial-up accesses user also is an ordinary telephone subscriber simultaneously, shown in figure one.Traditional public switch telephone network is generally all followed 60 seconds principle of mean busy hour and is planned and design, this is to add up according to the mean busy hour of common telephone call to draw, but the mean busy hour of Internet dial user online is but above 30 minutes.Just because of the long time property that Internet calls out, the serious inequality that has caused telephone traffic to distribute is to make the exchange network obstruction to maximum effect of public switch telephone network (PSTN) (to call the PSTN net in the following text).Internet calls out and not only to take the relaying speech channel for a long time, and the user to be used to browse time of computer screen many, the real time of downloading is few, makes that the utilization factor of relaying speech channel is not high, has wasted valuable line resource.How adjusting PSTN, to adapt to the demand of huge day by day Internet customer group, is a urgent problem.
For this reason, can people have proposed be diverted to the Internet dialing access service from the PSTN net as soon as possible the idea of Internet net, promptly so-called bypass.Actually or it is by the data traffic flow voice service stream of the current transmission of certain method identification user, then data traffic flow is shunted away on the net from PSTN, guaranteed that in this way the service quality of the last telephone service of PSTN is unaffected.This scheme is pratical and feasible, even portfolio increases later on, still can deal with problems, and multiple bypass technology therefore occurred.According to the difference of bypass point, can reduce two big classes, i.e. rearmounted bypass of switch and the preposition bypass of switch.
The rearmounted bypass of switch is called the trunk side bypass again, shown in figure two.In this structure, Internet calls out after by the exchange of inlet level switch and is bypassed on the data network.A is the bypass point among the figure.The advantage of this structure is when this technology is applied to local telephone network end office (EO), to have solved the congestion problems of interoffice junction and outlet level switch.And inlet level switch has still comprised transmission and signaling process process that Internet calls out, because bypass inlet level switch fully, thereby when a large amount of dialing access services access, does not have really to solve the congestion problems of telecommunications network.
The preposition bypass of switch is called the bypass of subscribers feeder side again, shown in figure three.In this structure, Internet calls out subscribers feeder side before the inlet level switch just by bypass.B is the bypass point among the figure.All network elements in the PSTN net (inlet level switch, junction line and outlet level switch) are all no longer born the transmission of Internet call-flow.But inlet level switch still will be responsible for the part correlation signaling process work that Internet calls out, and certainly, compares with rearmounted bypass scheme, and workload is much smaller.But, need a comparatively complicated mechanism as assurance (existing switch technology can't be supported), thereby in network, be difficult to implement owing to this technical requirement preposition equipment carries out cooperating with entering the mouth between the level switch.
Therefore, two kinds of present bypass technologies all exist unsatisfactory place when solving the bypass of Internet dialing access service.
The object of the present invention is to provide a kind of new online by-pass method, this method is not changing existing architecture of a telecommunication network, with conventional network equipment is not done under the prerequisite of technological transformation or upgrading, utilize the ability of telephone exchange self, thoroughly solve the congested difficult problem that telecommunications network is caused that causes by the Internet dialing access service.
The technical scheme that realizes the object of the invention is: a kind of method that realizes internet dialing access service bypass, what first call processing software by switch detected the current transmission of identification user is data traffic flow or voice service stream, then the data traffic flow that identifies is shunted away from public switch telephone network; Be characterized in, described data traffic flow be after the access level of the inlet level exchanger net element of public switch telephone network, before the selector stage by dialup access server by partial flow bypass path to the internet, and this data traffic flow is to select path to dialup access server by call processing software according to the access level sign at the current place of user.
Above-mentioned a kind of method that realizes internet dialing access service bypass, wherein, described is to be connected to dialup access server by the output port that is provided with in this access level from the data traffic flow that inserts the level bypass.
Above-mentioned a kind of method that realizes internet dialing access service bypass, wherein, described is to be connected to dialup access server by the out-trunk module that is provided with in this access level from the data traffic flow that inserts the level bypass.
Above-mentioned a kind of method that realizes internet dialing access service bypass, wherein, described path selection mode is meant on same access level network exchange unit and carries out routing.
Above-mentioned a kind of method that realizes internet dialing access service bypass, wherein, described routing is the access level network exchange unit sign according to identification services stream place, selection is connected same repeat circuit or the subscriber's line circuit to dialup access server that inserts on the level network exchange unit, and connect, export as Business Stream.
Because the present invention has adopted above technical scheme, with data traffic flow be after the access level that is positioned at inlet level switch, before the selector stage by partial flow bypass path to the internet, bypass selector stage, for being connected to same subscriber's line circuit or the repeat circuit that inserts on the level, can not go out to insert level and just can finish exchange, need not to enter the selector stage exchange.Thereby removed congested as the exchange network selector stage of public resource, reached the purpose of bypass telephone exchange.

A kind of method that realizes internet dialing access service bypass of the present invention, what first call processing software by switch detected the current transmission of identification user is data traffic flow or voice service stream, then the data traffic flow that identifies is gone out from the online inlet level switch internal shunt of PSTN.
Fig. 4 is a structure principle chart that typical switch software detects.What this figure had disclosed that call processing software by switch detects the current transmission of identification user is the data traffic flow or the method for voice service stream.As shown in the figure, when detecting to call out by call processing software, switch takes place, and after receiving the calling number and called number that inserts the user, call processing software can ask number analysis software that called number is analyzed, what identify user's request is any business, thereby makes switch know what next step should do.Be local call, so just go to check whether this is called idle; Be outbound call, so just remove to select the out-trunk of respective direction; Be intelligent network business, just go the execution of triggering intelligent network service logic.The present invention is exactly this recognition capability of utilizing switch, by the access code of number analysis software according to ISP, as 163 etc., identify the Internet dialing access service, and the indicating call process software is selected to be connected the same dialup access server port that inserts on the level with it for the dial-up user.The difference of the present invention and prior art be when selecting relaying except that according to service access code, also to choose the path of dialup access server according to inserting the level sign.
The network element of PSTN net comprises inlet level switch, junction line and outlet level switch, and wherein inlet level switch comprises line module, exchange network and trunk module again.As shown in Figure 5.The exchange network of each switch is divided into usually and inserts level and selector stage two-stage, inserts grade to be used to connect one group of line module or one group of trunk module, plays the effect of converging access service stream, and the Business Stream that converges is connected to selector stage exchanges.Selector stage is the core of exchange network, realizes the exchange of Business Stream, is a kind of public resource.
Fig. 6 is the exchange capacity synoptic diagram that switch inserts level; Insert the level access part of network in return, it has function of exchange equally, and for example, the time slot 1 (TS1) on the port one can exchange to the TS18 of port one 6, even also can exchange to the TS8 on the port one.That is to say,, can not go out to insert level and just can finish exchange, need not to enter the selector stage exchange for being connected to same subscriber's line circuit or the repeat circuit that inserts on the level.Utilize this characteristics, we just can link the circuit of dialup access server on the same access level that links to each other with user or relaying, thereby finish only through inserting the exchange of level.
The present invention is exactly a These characteristics of having utilized the switch exchange network to have, and with described data traffic flow be after the access level that is positioned at inlet level switch, before the selector stage by partial flow bypass path to the internet.Such selection is because the role of above-mentioned access level and selector stage is different, and selector stage in switch as the importance of public resource.Remove switch congestion be at all to remove the congested of exchange network selector stage, that is to say, bypass selector stage, also just reached the purpose of bypass telephone exchange.
Fig. 7 is a by-pass method synoptic diagram of the present invention; A kind of inboard bypass technology that the present invention proposes is, the bypass point is located between the access level and selector stage of switch exchange network, as shown in the figure, utilize the exchange capacity of access level and the traffic identification ability of switch, the repeat circuit of dialup access server is linked to each other by the same access level that links to each other with subscriber's line circuit or incoming trunk circuit, thus the bypass of realization dialing access service.The sensing of thick black arrow is by the sensing of the data traffic flow of bypass among the figure, and C is the bypass point.
By inserting data traffic flow after the level is by inserting the repeat circuit that is connected on the level or the subscriber's line circuit in the line module is connected to dialup access server with same.In whole switch, each is with line module or go on the access level that trunk module is connected to have at least a port to be connected with dialup access server.Perhaps, in whole switch, each is with line module or go on the access level that trunk module is connected to connect an out-trunk module that is connected with dialup access server at least.
Utilize exchange network on the switch to be divided into the characteristics that insert level and selector stage two-stage, utilize switch to have the ability of identification different business,, discern the Internet dialing access service according to the prefix analysis; Again the Internet dialup access server by the trunk module on the switch, receive respectively with switch in the subscriber's line circuit module/or the access level that is connected of incoming trunk circuit module on, and the function of exchange of utilizing the access level again, for being connected to same subscriber's line circuit or the repeat circuit that inserts on the level, can not going out to insert level and just can finish exchange.
The business that switch dials up on the telephone to Internet, when selecting relaying, will according to dial user's circuit/or the access level at incoming trunk circuit place decide and should select which outgoing trunk circuit to go to dialup access server, insert level to guarantee that dialing access service stream is only flowed through.
On software is realized, earlier detecting identification user current request by the calling of switchboard process software is that data service or voice service are (according to service access code, be prefix), insert the sign of level then according to the current place of user, selection is connected the same last path to dialup access server of level that inserts, and connect, thereby the data traffic flow that identifies is shunted away from the PSTN net.
Fig. 8 is that by-pass method of the present invention is applied in the example schematic in the local telephone network end office (EO); This is the example that this technology is implemented in local telephone network end office (EO).All users that suppose this local telephone network end office (EO) are connected on 8 access levels altogether.Therefore, the repeat circuit on the dialup access server, subscriber's line circuit will be connected on these 8 the access levels fifty-fifty.
The thick black line of band arrow shows the trend of data traffic flow.A subscriber dialing online on line module 1, as dial and connect into number 163.Call processing software module in the line module 1 detects and identifies this is a data service request, and according to inserting level 1 because this user is connected, so select to be connected a repeat circuit (as out-trunk module 4) that inserts on the level 1 to dialup access server, then this user is exchanged the repeat circuit that is connected on the out-trunk module 4 from line module 1, finish the path setting from the subscriber's line circuit to the dialup access server, the user's data Business Stream just flows to data network by this path, thereby has realized the purpose of bypass PSTN net.
Fig. 9 is that by-pass method of the present invention is applied in the example schematic in the local tandem office, and the workflow of the workflow of this example and above-mentioned example (shown in Figure 8) is similar, only is that line module is changed into into trunk module, so repeat no more.
Because the present invention has made full use of the self-ability of the switch that uses on the existing network, dialup access server still can pass through common trunk module access switch, thereby in the structure that is not changing existing telecommunications network with conventional network equipment is not done under the preceding topic of technical transformation or upgrading (comprising dialup access server), can thoroughly solve the congested difficult problem that telecommunications network is caused that causes by the Internet dialing access service.
