Embodiment

Call business networking structure of the present invention as shown in Figure 2, wherein:

Physical terminal can be fixed telephone terminal and/or personal handyphone system PHS telephone terminal;

The MS of tandem exchange possesses the SSP ability, by the public attribute information that inquiry is registered among the HLR, judges that whether caller/called number is and the corresponding public number of a plurality of physical terminal numbers, and a plurality of physical terminal numbers of the public number correspondence that continues;

The service switching point is used for replay call;

Attaching position register HLR is used to store the attribute information of public number and the corresponding relation of public number and a plurality of physical terminal numbers.

The service control point (SCP) is used to control the execution of intelligent service logic.In the database of SCP or among the HLR, there is a table to deposit DN (Directory Number, logical number) with RN (RoutingNumber, physical number) one-to-many mapping relations, DN is a public number, RN is the physical number of the pairing a plurality of physical terminals of public number, and wherein, RN is sightless to service-user.SCP is transformed to a plurality of physical terminal numbers to public number by this database of inquiry, and these physical terminal numbers of complete connection;

The user goes application to open the multimachine function No. one to the telecom operators business hall, the business hall shop assistant distributes a multimachine number DN for service-user, and this multimachine number can be user's PSTN termination number or phs terminal number.If assignment numbers is the PSTN termination number, the shop assistant can be simultaneously this number binding to one or more phs terminals; If assignment numbers is the phs terminal number, the shop assistant can be simultaneously on this number binding to one PSTN terminal or the phs terminal.Other PSTN or PHS physical terminal all have a telecommunication system inside to be used for the internal physical number RN of addressing, the shop assistant by the business interface the corresponding relation of DN and RN be tied in the scp database with HLR database in, service-user is only known the multimachine number that the shop assistant distributes, and do not know the number of other physical terminal, also be that other physical terminal also has only so outside number DN, other telecommunication user can only be called out this unique outside number DN when calling out these physical terminals.

Accompanying drawing 3 is the schematic flow sheet of public number among the present invention as called number, and its main implementation procedure is as follows:

301, calling terminal is called out terminal called, and terminal called is a public number, corresponding a plurality of physical terminal numbers; Route calls to called place tandem exchange;

302, tandem exchange is in HLR or tandem exchange's internal database, and whether the inquiry called number is public number, if, then return and trigger the access code that SCP goes up IN service, by access code mode, trigger intelligent business, this access code is the access code of internal system configuration, does not need the user to import; If not, 303 ', directly be routed to called number;

Those skilled in the art can know, also can be by end office's trigger intelligent business, and the tandem exchange here or end office (EO) can be called or the tandem exchange or the end office (EO) at caller place, tandem exchange or end office (EO) can possess the SSP ability.

303, intelligent network SCP is obtained calling number and called number from the IDP message that SSP reports, called number is carried out Full Match Search as DN in scp database, judge that whether this called number is and the corresponding public number of a plurality of physical terminal numbers, if words then a plurality of physical number RN of this public number DN correspondence are extracted.SCP charges to public number DN to caller A according to the charging policy that disposes in the scp database then, issue CONNECT then and operate to SSP, a plurality of RN numbers of DN correspondence simultaneously or order be issued to SSP and continue.

304, after SSP received the CONNECT operation that SCP issues, each the RN number that issues in CONNECT made a call, and when one of them is answered, sets up speech channel, can realize the calling and called conversation, discharges the calling of other terminal simultaneously.

305, behind the end of conversation, caller or Called Onhook, SSP report the expense of this conversation to give SCP, and by the expense of SCP from this conversation of charging account number deduction, this is called out fully and finishes, and discharges speech channel.

Accompanying drawing 4 is the schematic flow sheet of public number as calling number:

401, one of a plurality of physical terminal numbers corresponding with public number are called out called number, no matter use phs terminal also to be to use fixed telephone terminal to give orders or instructions, and call out to be routed to MS;

402, caller physical terminal number CAMEL-Subscription-Information in the inquiry HLR of tandem exchange or the tandem exchange's internal database, judge that whether this caller is and public number corresponding physical termination number, if, then by access code mode trigger intelligent business, this access code is the access code of internal system configuration, does not need the user to import; If not, then should call out directly be routed to called;

Those skilled in the art can know, also can be by end office's trigger intelligent business, and the tandem exchange here or end office (EO) can be called or the tandem exchange or the end office (EO) at caller place, tandem exchange or end office (EO) can possess the SSP ability.

403, intelligent network SCP is obtained calling number and called number from the IDP message that SSP reports, and calling number can be RN or the pairing DN of RN in reporting the IDP message of SCP; Calling number is carried out Full Match Search as DN or RN in scp database,, then a plurality of physical number RN of this public number DN correspondence are extracted if this calling number is DN.If calling number is the RN of public number correspondence, service logic backup calling number RN, and calling number is transformed to DN by RN according to the corresponding relation of DN that preserves in the scp database and RN, the follow-up business logic is that DN handles according to calling number, like this, in the caller identification of called number, will show public number, rather than the physical terminal number, and telephone expenses are also remembered on public number.

At SCP before SSP issues link order, whether also will inquire about called number in the SCP internal database is public number, if, then in HLR or SCP internal database, inquire about the pairing a plurality of physical terminal numbers of this called number, SCP issues CONNECT and operates to SSP then, in CONNECT a plurality of RN numbers of public number correspondence are issued to SSP and continue, calling number is DN.CONNECT is operating as the CONNECT operation of expansion, a plurality of RN numbers fill in respectively in the destination address number and a plurality of additional called number of CONNECT, the DN number is filled in the calling number zone of CONNECT signaling, after SSP receives the CONNECT operation that SCP issues, each the RN number that issues in CONNECT makes a call, can realize the calling and called conversation when one of them is answered, discharge the calling of other terminal simultaneously, the terminal called caller identification is public number DN; If called number is not a public number, then SSP will call out directly and continue to called number.

SCP charges to called number to DN according to the charging policy that disposes in the scp database, if called number also is this public number DN, so this time calls out and adopts special charging policy, such as not chargeing or carrying out lower Freight Basis etc.;

404, behind the end of conversation, caller or Called Onhook, SSP report the expense of this conversation to give SCP, and by the expense of SCP from this conversation of public number DN deduction, this is called out fully and finishes, and discharges speech channel.

In step 303, when SCP issues the CONNECT instruction to SSP, can issue simultaneously or sequentially, realize calling simultaneously or sequentially to a plurality of physical terminals.

When calling out simultaneously, CONNECT is operating as the CONNECT operation of expansion, a plurality of RN numbers are filled in respectively in the destination address number and a plurality of additional called number of CONNECT, after SSP receives the CONNECT operational order, with simultaneously comprising a plurality of physical terminals make a call; At this moment, the signaling process figure between SCP and the SSP as shown in Figure 5:

The call request that SSP will call out public number sends to SCP, and the initialization test point (Detect Point, DP);

After SCP receives the call request of calling out public number, report BCSM (Basic Call State Model, Basic Call State Model BCSM) incident to the SSP request of issuing, comprise that The Calling Party Hooks On, incident is abandoned in caller (DP9/1, DP10); Inquire a plurality of physical terminal numbers corresponding then with public number; And to SSP issue the request report the BCSM event action, comprise logic configuration DP4/DP5/DP6/DP7/DP9 (2) incident, each event definition is as follows:

DP4:routeSelectFailure, route selection failure;

DP5:oCalledPartyBusy, Called Busy;

DP6:oNoAnswer, called no response;

DP7:oAnswer replys;

DP9:oDisconnect, on-hook is divided into the calling and called on-hook, and DP9 (1) is that The Calling Party Hooks On, and DP9 (2) is a Called Onhook;

DP10：oAbandon

SCP then issues connection (CONNECT) message and gives SSP, carries a plurality of RN number informations in CONNECT; Specifically the mode of carrying is: a RN number is placed in the routing address territory, destination of CONNECT message, and the 2nd RN number is placed in additional called number 1 territory, and the 3rd RN number is placed in additional called number 2 territories ... and the like.After SSP receives CONNECT message, make a call to each RN number, the RN number begins ring; Some terminal called off-hooks are replied, SSP reports the DP7 signaling to give SCP, in the DP7 signaling message, receivingSideID parameter to Leg ID (debit ID) is expanded, this parameter is the hyte of 8 bits, and the present invention does not make amendment to its structure, only utilizes its high 4 bits, low 4 bits are 2 constant, expression callee incident; Its high 4 bits are filled to the sequence number of replying the user.For example: 0x12 represents that first replys with vibration numbers, and 0x22 represents that second replys with vibration numbers, and 0x32 represents that the 3rd replys with vibration numbers ... the rest may be inferred;

After SCP receives the DP7 signaling, issue Apply Charging (AC) signaling and give SSP;

After SSP receives the Apply Charging signaling, start immediately and charge; The calling and called end of conversation, behind caller or the Called Onhook, SSP reports charging application paper (ACR);

SSP reports the BCSM event report to give SCP, and SCP receives that the back discharges this calling.

When a plurality of physical terminal of sequence call, the signaling process figure between SCP and the SSP as shown in Figure 6,

Only the distinctive points to Fig. 6 and Fig. 5 signaling process is described as follows:

SCP sends a plurality of CONNECT instructions continuously, includes only a RN number in each CONNECT instruction, when SSP receives each CONNECT instruction RN number in this instruction is made a call.Issue ICA (number is RN1)/RRBE/AC/CWA at first earlier as SCP and operate to SSP, SSP initiates the call attempt to first terminal; SCP issues ICA (number is RN2)/RRBE/AC/CWA once more and operates to SSP, and SSP initiates the call attempt to second terminal; All initiate call attempt up to a plurality of RN like this to the DN correspondence.If in this process, if there is the RN number to reply, SSP then reports the incident of replying to SCP, and SCP promptly discharges other RN number of not replying, and no longer sends the CONNECT instruction.At this moment, SCP issues the merging call leg and operates to SSP, and caller and called two sections speech channels are coupled together, SSP reports the merging call leg to report to SCP after the successful connection, and the continuation of hair band parameter is operated to SSP under the SCP, the connection of indicating call, calling and called begin conversation, and SSP begins to charge.Behind caller or the Called Onhook, SSP reports charging report to give SCP, reports on-hook BCSM incident to give SCP, and SCP discharges this calling and charging.

Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
