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, MSC a receive the calling that calling number is initiated, and the CAMEL-Subscription-Information corresponding according to calling number triggers business, with MSCa position information, sends to SCPa through IDP message.

Step 202, SCPa carry out authentication to calling number after receiving the IDP message of MSCa transmission, after the authentication success, and through 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 to step 205, identical with the flow process of step 103 shown in Figure 1 to step 105, repeat 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 through 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 to step 208, SCPa receive the ERB message that MSCa sends; 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 to step 212, MSCa receive the AC message that SCPa sends; 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 to step 214 is similar with the flow process of above-mentioned steps 108 to step 109; Different is; The indication information that SCPa reports based on MSCa can be known 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, specifically be any redirection business because SCPa can not confirm called number side customization in advance, therefore; Can be provided with in advance, SCPa is after main calling is initiated, through send 150 labels to MSC; The redirection business of notice MSC monitoring called number side is replied as if called number, 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 150 corresponding push-notification-answer to SCP, and 151 corresponding push-notification-answer, represent then that the called number side has customized to reply the back Call Forwarding services, and this business can intactly monitor by SCP.SCP can handle, like charging, redirect number authentication or the like based on the back Call Forwarding services of replying that monitor accordingly.

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

Among this embodiment, SCPa is earlier through 150 incidents in the RRBE message arrangement, and notice MSC a 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 to step 310, MSCa send through AC message based on the SCPa that regularly receives can converse based on the rate budget between calling number and the called number; Regularly report the charge informations such as the duration of call between calling number and the called number through 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 to step 312, MSCa monitor the onhook event of called number side, and sending push-notification-answer to SCPa is ERB message, and reporting the indication information of this onhook event, redirection business to caller SCPa is 150 labels and redirect number; MSCa is through 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 through ACR message, report, to the interior during this period of time ring duration of redirect number side off-hook from the on-hook of called number side.

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, the duration that can converse between budget calling number again and the redirect number sends to MSCa with budget result through AC message; And based on preset ring duration based accounting strategy, to the ring duration based accounting.

Ring duration based accounting strategy can be as before mention 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 by operator as required.

Mutual calling number is to the call meters relevant information between the redirect number between step 317 to 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 be through ERB message, reports calling subscriber or redirected user's onhook event to SCPa, and 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 be redirected finishing, 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 charges to calling party's fee payable in this section ring duration according to preset charging policy, and 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 and change, the redirection events that takes place when only needing MSC to report redirect number side off-hook flow process shown in Figure 3; After SCPa is known this incident; Based on the rate between calling number and the redirect number, the calling party is chargeed, and do not need flow process that kind as shown in Figure 3 to make SCPa further can monitor above-mentioned ring duration; Correspondingly, also the expense in the ring duration is rationally chargeed with regard to being difficult to.In addition, when specifically realizing, 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 the CAMEL-Subscription-Information corresponding according to calling number triggers business, with MSCa position information, sends to SCPb through IDP message.

After step 402 to step 405, SCPb receive the IDP message of MSCa transmission, send the RRBE message that disposes 152 labels, the redirection business of notice MSCa monitoring called number side to MSCa. 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 through 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 to step 407, MSCa send push-notification-answer to SCPb, and reporting the indication information of the redirection business that monitors to SCPb is 152 labels; MSCa is through 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 representes that called flow finishes, and need not charge to the called subscriber.

Step 409, MSCa with call proceeding on redirect number.

Flow process embodiment illustrated in fig. 4 finishes.Among this embodiment, to 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.
