Description

Method for processing business and communication equipment

Technical field

The present invention relates to the intelligent network technology field, relate in particular to a kind of method for processing business and communication equipment.

Background technology

Operator often can be based on existing intelligent network technology, for the user provides as redirection business such as calling transfer, for the user provides convenience.

Referring to Fig. 1, Fig. 1 is the calling procedure figure of existing redirection business, the network side communication apparatus that participates in this flow process comprises: mobile services switching centre (MSC, Mobile service Switching Center) a, Visited Location Registor (VLR, Visitor Location Register), Service Switching Point (SSP, and the service control point of intelligent network (SCP, Service ControlPoint) a Service Switching Point).Wherein, VLR and SSP can be with being located on the MSCa.To being briefly described below of this calling procedure:

Step 101, MSCa receive the calling that the calling subscriber initiates, and be professional according to calling subscriber's CAMEL-Subscription-Information triggering, directly with MSCa position information, sends to SCPa by Initial Detection Point (IDP, InitialDetection Point) message.

Step 102 is to 104, after SCPa receives IDP message, account to the calling subscriber carries out authentication, after the authentication success, determine the caller rate according to calling number and called number, and calling subscriber's account balance is converted to the duration of call, send request report BSCM incident (RRBE, Request ReportBCSM Event) message, Apply Charging (AC, Apply Charging) message and continue operation (Continue) message to MSCa, the notice MSCa connection of conversing.Wherein, RRBE message is carried the event information that needs the MSCa monitoring, the information that AC message is carried the duration of call.

Step 105 is to 106, because the called subscriber has customized redirection business, so MSCa discharges being connected of calling number and called number, and MSCa arrives redirect number according to called subscriber's redirection business with this Call Forwarding.

In step 107, calling subscriber and the called subscriber's communication process, MSCa reports call meters information by ACR message to SCPa.

The charge information that the charge information that MSCa reports to SCPa still communicates based on calling number and called number, rather than the charge information between calling number and the redirect number.

Step 108 to 109, calling and called either party on-hook, SCPa is by BCSM event report (ERB, Event Report BCSM) message, notice MSCa onhook event, by the MSCa call release, the charge information that SCPa reports according to MSCa, this call meters of processing calling subscriber notifies this flow process to finish.

The inventor finds, in the above-mentioned flow process, Call Forwarding is transparent to SCPa, promptly because SCPa can not monitor the redirection business of calling, therefore, be difficult to correctly handle redirection business, as SCPa still based on the rate between calling number and the called number, to actual be that calling number is chargeed to the calling of redirect number.Therefore, if calling number is local call to the calling of called number, and calling number is non-local call to the calling of redirect number, and the inconsistent situation of expense that the charging result that SCPa then can occur and reality are conversed and produced causes damage to operator; Otherwise if user a is that call out in the strange land to the calling of user b, and user a is local call to the calling of user c, the inconsistent situation of expense that the charging result that SCPa also can occur and reality are conversed and produced, and cause damage to the user.

Therefore, in the existing intelligent network technology, service control point is difficult to monitor contracted user's redirection business.

Embodiment

The inventor analyzes and draws, why SCP can not be at the redirection business of callee's (called number), the calling party is reasonably chargeed, reason comprises that callee's redirection business is transparent to SCP, in other words, SCP can not the perception callee redirection business, therefore, the situation that is difficult to have customized at the callee redirection business is handled accordingly.

In the embodiments of the invention, by by the controlling call entity of being responsible for call proceeding, the redirection business of the called number that monitors is reported SCP, make SCP can know this redirection business, follow-up, SCP can charge accordingly at the redirection business of knowing, authentication or the like is handled.In the embodiment of the invention, controlling call entity can comprise MSC; Perhaps, MSC and VLR; Perhaps, MSC, VLR and SSP or the like communication network element that when replay call, can relate to.

The concrete scheme of implementing of the present invention mainly comprises: if calling number makes a call to called number, then SCP notification call controlled entity is monitored the redirection business of called number; Described SCP receives the push-notification-answer that described controlling call entity returns, and parses the indication information that the expression that comprises in the described push-notification-answer monitors described redirection business.

Usually, the callee customized redirection business can comprise: the called number side is not replied the calling that calling number is initiated, and call out the preceding Call Forwarding of replying that directly is redirected to redirect number, perhaps, after called subscriber answer calling and on-hook, calling continues to be redirected to the back Call Forwarding of replying of redirect number, in replying this redirection business of back Call Forwarding, the process that calling can relate to comprises: the calling number side makes a call, called number side off-hook, the on-hook of called number side, begin to reply the back Call Forwarding this moment, also promptly replys the beginning incident of back Call Forwarding; The ring of redirect number side, redirect number side off-hook is replied the back Call Forwarding and finish this moment, promptly replys the End Event of back Call Forwarding.In the practical application,, also may enumerate no longer one by one for the user provides other redirection business based on the change of development of Communication Technique and carrier policy.

Below in specific embodiment, in conjunction with the accompanying drawings, and the redirection business of above specifically mentioning, describe the redirection business how SCP monitors the called number correspondence in detail, and how SCP carries out respective handling based on the redirection business that monitors.

In the embodiment of the invention, can set in advance the redirection business mark that is used to indicate redirection business, concrete as, RRBE message and the ERB message of expansion INAP/CAP, in event type, increase redirection events, as to increase label be 150,151,152 or the like event types, can be regarded as the concrete form of redirection business mark as labels such as 150,151,152, and available these labels come the concrete redirection business of mark, require the preceding Call Forwarding of replying that controlling call entities report as available 150 SCP that come mark to handle calling service; Available 150, the 151 mark SCP beginning incident (oRedirectBegin) and the End Events (oRedirectAnswer) of replying the back Call Forwarding that require controlling call entity to report respectively; The redirection business (tRedirectBegin) that the SCP of available 152 marks processing called service requires controlling call entity to report.

Enumerate through the event type example of expansion as follows:

EventTypeBCSM ::＝ENUMERATED{

Above-mentioned example has mainly been enumerated the relevant parameter of 150 incidents, comprising: redirection information (redirectInfo), redirect number (redirectNumber), be redirected time and time zone (timeAndTimezone) or the like.About the relevant parameter of 151 incidents and 152 incidents can dispose as required, repeat no more.

Among the embodiment, the called subscriber customized redirection business be to reply preceding Call Forwarding services.Controlling call entity is the MSCa that comprises VLR and SSP.

Referring to Fig. 2, Fig. 2 is the flow chart that SCP handles redirection business in the one embodiment of the invention.This flow process can may further comprise the steps:

Step 201, MSCa receive the calling that calling number is initiated, and be professional according to the CAMEL-Subscription-Information triggering of calling number correspondence, with MSCa position information, sends to SCPa by IDP message.

Step 202, SCPa carry out authentication to calling number after receiving the IDP message of MSCa transmission, after the authentication success, and by 150 incidents in the RRBE message arrangement, the redirection business of notice MSCa monitoring called number.

In the present embodiment, the redirection business of called number side is to reply preceding Call Forwarding services.

Step 203 is to step 205, and is identical to the flow process of step 105 with step 103 shown in Figure 1, repeats no more.

Step 206, MSCa monitor the called subscriber and have customized and reply preceding Call Forwarding services, sending push-notification-answer to SCP is ERB message, the indication information that replying preceding Call Forwarding services that expression is monitored called number sends to MSCa by this ERB message, and this indication information is a redirect number.

In the present embodiment, MSCa can be known whether the called subscriber has customized according to called subscriber's CAMEL-Subscription-Information and reply preceding Call Forwarding services.

After step 207 is received the ERB message that MSCa sends to step 208, SCPa, parse redirect number wherein, redirect number is carried out authentication, and according to the rate between calling number and the redirect number, and the telephone expenses remaining sum of calling number side, the duration that can converse to calling number and redirect number carries out budget, sends the AC message of the budget result of carrying the duration of call to MSCa.

Step 209 receives the AC message of SCPa transmission to step 212, MSCa, with Call Forwarding on redirect number, mutual calling number is to the call meters relevant information between the redirect number between SCPa and the MSCa, and based on the conversion result of the duration of call, monitoring is called out.

Step 213 is similar to the flow process of step 109 to step 214 and above-mentioned steps 108, different is, the indication information that SCPa reports based on MSCa, can know the preceding Call Forwarding of replying of called number side, therefore, the ticket expense that produces generates based on the rate between calling number and the redirect number, and can not occur caller being chargeed or other irrational charging case based on the rate between calling number and the called number.

Above-mentioned flow process embodiment illustrated in fig. 2 finishes.

Among another embodiment, the customized redirection business of called number side is to reply the back Call Forwarding services.Controlling call entity is the MSCa that comprises VLR and SSP.Among this embodiment, because what SCPa can not determine the customization of called number side in advance specifically is any redirection business, therefore, can set in advance, SCPa is after main calling is initiated, by send 150 labels to MSC, the redirection business of notice MSC monitoring called number side, if called number is replied, then for to guarantee that SCP can monitor the whole redirection business of called number side, 150 labels that SCP sends can represent to notify the MSC monitoring to reply the beginning incident of back Call Forwarding, further, SCP sends 151 labels to MSC, and expression requires the End Event of replying the back Call Forwarding of MSC monitoring called number side.If MSC has returned the push-notification-answer of 150 correspondences to SCP, and the push-notification-answer of 151 correspondences, represent then that the called number side has customized to reply the back Call Forwarding services, and this business can intactly be monitored by SCP.SCP can handle, as charging, redirect number authentication or the like accordingly based on the back Call Forwarding services of replying that monitor.

Referring to Fig. 3, Fig. 3 is the flow chart that SCP handles redirection business among another embodiment.This flow process may further comprise the steps:

Step 301 is to step 305, and is similar to the flow process of step 205 with above-mentioned steps 201.

Among this embodiment, SCPa is earlier by 150 incidents in the RRBE message arrangement, and notice MSCa monitors the redirection business of called number.

Step 306, MSCa report called subscriber's off-hook event to SCPa.

Step 307, SCPa are known called number side answering call after receiving called subscriber's off-hook event that MSCa reports, and the RRBE message that then will dispose 151 labels sends to MSC.

As mentioned above, because of called number side off-hook, then for to guarantee that SCPa can monitor the redirection business of called number side, 150 labels that send of SCPa can be used for notifying the beginning incident that replying the back Call Forwarding of MSC monitoring called number side before, and 151 labels that SCPa sends in this step 307 can be used for notifying the End Event that replying the back Call Forwarding of MSC monitoring called number side.

The duration that the SCPa that step 308 sends by AC message based on the SCPa that regularly receives to step 310, MSCa can converse based on the rate budget between calling number and the called number, regularly report charge informations such as the duration of call between calling number and the called number by ACR message to SCPa, until the on-hook of called number side, MSCa discharges the calling connection of calling number to called number.

Step 311 monitors the onhook event of called number side to step 312, MSCa, and sending push-notification-answer to SCPa is ERB message, and the indication information that reports this onhook event, redirection business to caller SCPa i.e. 150 labels and redirect number; MSCa is by the duration of call between ACR information reporting calling number and the called number, and SCPa is according to this duration of call, and the charging rate between calling number and the called number, calculates main telephone expenses of calling out.

After step 313, SCPa receive the ERB message of MSCa transmission, to the redirect number authentication that parses, after the authentication success, based on the charging rate between calling number and the redirect number, and the telephone expenses remaining sum of calling number side, again the duration that can converse between budget calling number and the redirect number passes through AC message informing MSCa with budget result.

After step 314, MSCa receive the AC message of SCPa transmission, redirect number is arrived in Call Forwarding, and, monitor the duration of call of calling number to redirect number based on the duration of call budget result that SCPa provides.

Step 315, redirect number side off-hook, it is ERB message that MSCa sends push-notification-answer to SCPa, reporting the off-hook event of redirect number side, the indication information of redirection business to SCPa is 151 labels, and by ACR message, report from the on-hook of called number side, to the interior during this period of time ring duration of redirect number side off-hook.

After step 316, SCPa receive the ERB message that MSCa reports, after parsing 151 labels wherein, based on the charging rate between calling number and the redirect number, again the duration that can converse between budget calling number and the redirect number, budget result is sent to MSCa by AC message, and based on default ring duration based accounting strategy, to the ring duration based accounting.

Ring duration based accounting strategy can be as previously mentioned based on the rate accounting between calling number and the called number, maybe can be based on the rate accounting between calling number and the redirect number; Also can be not charge.This strategy can be formulated as required by operator.

Step 317 is to mutual calling number is to the call meters relevant information between the redirect number between step 319, MSCa and the SCPa, and the monitoring calling subscriber is to the calling that is redirected between the user.

Step 320 to step 321, MSCa by ERB message, report calling subscriber or redirected user's onhook event to SCPa, SCPa goes out calling number to the cost of the phone call between the redirect number.

End embodiment illustrated in fig. 3, among this embodiment, mutual based on the monitor message of twice redirection business between SCPa and the MSC, 150 label indications are replied the beginning incident of back Call Forwarding and the End Event that 151 label indications are replied the back Call Forwarding, make SCP can intactly monitor the redirection business of called number side, not only can be after being redirected end, based between calling number and the redirect number rate, the main calling chargeed, can also based on monitor from the on-hook of called number side to redirect number side off-hook during this period of time in, the ring duration of redirect number side, according to default charging policy calling party's fee payable in this section ring duration is chargeed, the charging of whole calling procedure is rationalized.

How above-mentioned flow process shown in Figure 3 makes SCPa monitor an embodiment of replying the back calling transfer of called number side if only having provided.In the practical application, also can do some changes to flow process shown in Figure 3, the redirection events that takes place when only needing MSC to report redirect number side off-hook, after SCPa is known this incident, based on the rate between calling number and the redirect number, the calling party is chargeed, flow process makes SCPa further can monitor above-mentioned ring duration like that and do not need as shown in Figure 3, correspondingly, also the expense in the ring duration is rationally chargeed with regard to being difficult to.In addition, during specific implementation, can adopt other modes to notify SCPa redirection business about the called number side, key is to make SCPa can monitor the redirection business of called number side.

In addition, for above-mentioned Fig. 2 and flow process shown in Figure 3, if redirect number is non-one-way charge side, then SCPa or other SCP also can rationally charge to redirect number based on the rate between calling number and the redirect number.

Above-mentioned Fig. 2 and flow process shown in Figure 3 have mainly embodied the scene how SCP that handles calling service handles the redirection business of called number side, illustrate the disposition of the SCP of processing called service to the redirection business of called number side below.

In yet another embodiment of the invention, the called subscriber customized redirection business be to reply preceding Call Forwarding services, SCPb handles called service, SCPb notice MSCa reports the redirection business that monitors, so that after calling is redirected to redirect number, stop charging to the callee.

Referring to Fig. 4, Fig. 4 is again the flow chart that SCP handles redirection business among the embodiment.This flow process can may further comprise the steps:

Step 401, MSCa receive the calling that calling number is initiated, and be professional according to the CAMEL-Subscription-Information triggering of calling number correspondence, with MSCa position information, sends to SCPb by IDP message.

Step 402 sends the RRBE message that disposes 152 labels to MSCa after receiving the IDP message of MSCa transmission to step 405, SCPb, the redirection business of notice MSCa monitoring called number side. SCPb is based on the rate between calling number and the called number, the budget called number can with the duration of calling number conversation, budget result is sent to MSCa by AC message; MSCa receives the AC message that SCPb sends, and according to the preceding Call Forwarding services of replying of called subscriber's customization, discharges the connection of calling number to called number.

It is ERB message that step 406 sends push-notification-answer to step 407, MSCa to SCPb, and reporting the indication information of the redirection business that monitors to SCPb is 152 labels; MSCa is by ACR message, and reporting the duration of call between called number and the calling number is zero.

Step 408, SCPb parse 152 labels after receiving the ERB message that MSCa reports, and send TC-END message to MSCa.

In this flow process, TC-END message represents that called flow finishes, and does not need the called subscriber is chargeed.

Step 409, MSCa with call proceeding on redirect number.

Flow process embodiment illustrated in fig. 4 finishes.Among this embodiment, at the preceding Call Forwarding services of replying of called number side, the call charging that SCPb does not still have neither part nor lot in the callee, but by the SCPa of caller one side to the call charging between calling number and the redirect number.To the charging of redirect number, can reach the rate accounting of redirect number based on the duration of redirect number actual participation calling to calling number, for attainable prior art, do not give unnecessary details.

The SCP that relates in the various embodiments described above can divide into caller SCP such as the SCPa that handles calling service on function, with the SCP such as the SCPb that handle called service, to from network entity, SCPa and SCPb can be that same SCP finishes, and also can be set up separately by different SCP.
