Description

The implementation method of supplementary service charging for intelligent user and system

Technical field

The present invention relates to network communications technology field, relate in particular to a kind of implementation method and system of supplementary service charging for intelligent user.

Background technology

At GSM (global system for mobile communications) and 3GPP (The 3rd Generation PartnershipProject, third generation partner program) definition ECT (Explicit Call Transfer in, the show Calls transfer), CD (Call Deflection, Call Deflexion), CCBS (Completion of Call toBusy Subscriber, meeting busy the calling finishes) and MPTY (MultiParty, MPTY) mobile subscriber's live and work needs have been enriched in supplementary service widely; Wherein the ECT active user withdraws from from two callings that participate in, and connects two remaining sides, can realize calling out switching flexibly.CAMEL (Customised Applications for Mobile network Enhanced Logic in addition, the mobile network strengthens the customized application of logic), professional thought of separating with exchange is proposed, provide and resembled PPS (Precision Positioning Service, PPS) and MVPN (Mobile VirtualPrivate Number, mobile private numbering plan) etc. professional.

Enjoy ECT, CD, CCBS and MPTY supplementary service for non intelligent user, ticket is produced by MSC (Mobile Switching Center, mobile switching centre), and MSC can know whether supplementary service has taken place, and the details of supplementary service, as the information such as duration of different phase; For the intelligent subscriber that possesses the CAMEL subscription data, its ticket of calling out generation is by SCP (Service ControlPoint, service control point) produces, at present because SSP (Service Switching Point, Service Switching Point) it is limited to send the information of SCP to, therefore SCP can't write down accurate information in the ticket that produces, and will cause intelligent subscriber to have the difficulty of charge accounting mistake like this when enjoying ECT, CD, CCBS and MPTY supplementary service.

In 3GPP 22.091 agreements, stipulated to charge to require: initiate the user of ECT service request, after the ECT success, still produce the CDR (Call Detail Record, call detail recording, i.e. charging bill) of two callings at ECT.

The user who supposes initiation ECT business is A, and two other user who converses with user A is B and C, still produces calling A-B and the CDR that calls out A-C so after the ECT success; And in CDR, show and successfully initiate the ECT supplementary service.Before the ECT success, user A takies Radio Resource and network trunk resource, participate in two callings, after the ECT success, user A no longer takies Radio Resource and network trunk resource, no longer participate in calling out, so should implement different charging policy before and after the ECT success, the timestamp of ECT success also just becomes the cut-point of charging.

Charging for the ECT supplementary service has three kinds of implementations: monthly rent charging way, whole charging way and independent counting mode.

The clearing of monthly rent charging way are simple, can not deduct fees to the user according to conversation length, and operator can't determine charging policy.This mode does not have extra demand to MSC, therefore can be indifferent to.

For whole charging way, be indifferent to the timestamp of ECT success, after the ECT success, still call out according to A-B calling and A-C and charge, promptly user A is produced two charging bills, the ECT supplementary service once took place in indication in the ticket, the charging center is carried out discount according to this sign and is handled, but because ECT surrounding time length ratio can not determine that concrete discount ratio also can't be determined, is a kind of approximate charging way.

The independent counting mode is a kind of accurate charging way, can before and after the ECT success, produce the different charge ticket respectively to the user who initiates the ECT supplementary service, four tickets of promptly final generation, two tickets before the ECT success are called out the same with common A-B calling with A-C, be not with the ECT sign, two tickets after the ECT success carry the ECT sign.The charging center relies on back two tickets, can the flexible definition charging policy.

If initiating the user of ECT supplementary service is non-intelligent subscriber, charging bill is produced by MSC, can realize whole charging way and independent counting mode fully, and which kind of charging way concrete the application takes, and is determined by operator.

If but the user who initiates the ECT supplementary service is intelligent subscriber, the charging bill of intelligent subscriber is produced by SCP, and the information that ticket produces is subject to the information that SSP offers SCP.At present at CAP (CAMEL Application Part, CAMEL Application Part) interface, only at IDP (InitialDetection Point, Initial Detection Point) carries Service Interaction Indicators Two (service interaction deictic word 2) parameter in the message, in this parameter, there is ECT Treatment Indicator (ECT deictic word) information, SCP can know active user's ECT supplementary service of having contracted according to this information, but whether initiate the ECT supplementary service, SCP has no way of learning; SCP can't learn that also the ECT supplementary service calls the timestamp of success in addition, and the duration of call of ECT supplementary service before and after calling successfully.Therefore, if for the signatory ECT supplementary service of intelligent subscriber, want to realize whole the charging or independent counting unusual difficulty just.

At above-mentioned technical problem, in CAMEL2, defined SS-CSI (Supplementary ServiceNotification CAMEL Subscription Information, supplementary service CAMEL subscription data), when the user initiates ECT, CD, during the success of MPTY business, VLR (Visit Location Register, VLR Visitor Location Register) checks this user SS-CSI that whether contracted, if have then check triggering criterion, after the criterion inspection is passed through, VLR can send the supplementary service call notification to SCP, for the CCBS business, by HLR (Home Location Register, attaching position register) sends the supplementary service call notification, as shown in Figure 1.

Though SS-CSI can notify SCP user to initiate the ECT supplementary service, if but when asking the user to contract, gsmSCF Address among the SS-CSI must with O-CSI (Originating CAMEL SubscriptionInformation, the mobile originating CAMEL Subscription Information)/VT-CSI (VMSC TerminatingCAMEL Subscription Information, the VMSC Terminating CAMEL Subscription Information) the gsmSCF Address unanimity in, make in same SCP the service logic of handling O-CSI/VT-CSI and the service logic of treatment S S-CSI to associate, could generate corresponding ticket like this, as shown in Figure 2.

For SCP, O-CSI/VT-CSI service logic and SS-CSI service logic are two independently processing procedures, SCP is when receiving the supplementary service call notification, need be according to user's MSISDN (Mobile Station ISDN (Integated Services Digital Network, integrated services digital network) Number, mobile station ISDN number) or IMSI (International Mobile SubscriberIdentifier, IMSI International Mobile Subscriber Identity) search for all O-CSI/VT-CSI Processing tasks, such processing mode can influence the handling property of SCP.

Owing in supplementary service call notification message, do not carry the timestamp of ECT success, SCP can not confirm as the moment of receiving the supplementary service call notification timestamp of ECT success, even carry timestamp, it also is absolute time, and can not accomplish absolute time synchronized between MSC and the SCP, therefore, SCP still can't accurately obtain A-B and A-C call out in the time span of ECT before and after calling successfully, so, the ECT independent counting of realizing intelligent subscriber based on SS-CSI is infeasible, promptly allow to temporarily realize the independent counting mode, but can influence the SCP runnability, and billing accuracy is not high.

Summary of the invention

Embodiment

Core concept of the present invention is: in calling procedure after intelligent subscriber successfully initiates supplementary service (such as ECT, MPTY, CW, CH etc.), the corresponding supplementary service that SCP reports according to SSP call success message and charge information determine described supplementary service call successfully before and after the duration of call, and the processing of chargeing of the charging policy before and after calling successfully according to corresponding supplementary service.

In actual applications, can increase SSNotifyEvent (Supplementary Service Notify Event, supplementary service call notification incident) at supplementary services such as ECT, MPTY, CW, CH realizes reporting corresponding supplementary service to call the message of success to SCP.It is to report in MO (mobile originating), MVT (the mobile VMSC termination) flow process that mobile originating CAMEL Subscription Information O-CSI, mobile terminating CAMEL subscription data VT-CSI are triggered that incident is called successfully in supplementary service.

The concrete parameter of SSNotifyEvent is as follows:

Event type	O-SSNotifyEvent or T-SSNotifyEvent
		Calling party	Leg1 or Leg2
Monitoring mode	EDP-N or EDP-R
		The DP designation criteria	At the supplementary service call notification, provide different supplementary service types, as ECT, MPTY, CW, CH etc.

Wherein, when supplementary service occurred in the MO end, event type was O-SSNotifyEvent, and when supplementary service occurred in the MVT end, event type was T-SSNotifyEvent;

When calling party was the calling party, the calling party parameter was Leg1, and when calling party was the callee, the calling party parameter was Leg2;

EDP (English, Chinese)-N (NotifyAndContinue) expression notification type incident, EDP-R (Request) expression request type incident.

For the present invention there being further understanding, be that also the present invention will be described in detail in conjunction with the accompanying drawings for example with the ECT supplementary service below.

The specific embodiment of the present invention comprises the steps: as shown in Figure 3

Step 31: after the intelligent subscriber request of making a call, SSP reports IDP message to SCP.

Carry Service Interaction Indicators Two parameter in this IDP message, the ECT supplementary service if intelligent subscriber has contracted should be carried ECT Treatment Indicator information in this parameter.

If when the ECT supplementary service will occur in the MO end, SSP reported IDP message to SCP in the O-CSI IN process;

If when the ECT supplementary service will occur in the MVT end, SSP reported IDP message to SCP in the VT-CSI IN process.

After step 32:SCP receives IDP message, check Service Interaction Indicators Two parameter, if carried ECT Treatment Indicator information in this parameter, determine that then this intelligent subscriber belongs to the ECT contracted user, at the RRBE that issues to SSP (Request Report BCSM (Basic CallState Model, Basic Call State Model BCSM) Event, request report BCSM incident) middle configuration SSNotifyEvent.

The DP designation criteria parameter of this incident is ECT, and the monitoring mode parameter can be determined as required, is configured to EDP-N under the general situation;

If the ECT business will occur in the MO end, type of event parameter is O-SSNotifyEvent, and the calling party parameter is Leg1;

If the ECT business will occur in the MVT end, type of event parameter is T-SSNotifyEvent, and the calling party parameter is Leg2.

When SCP issues RRBE message to SSP, also issue AC (Apply Charging, Apply Charging) and Continue (the professional continuation) message to SSP.

After step 33:SSP receives the RRBE message and AC and Continue message that SCP issues, SSP proceeds call treatment, when called party answer, begin collecting charging information (the normally duration of call of intelligent subscriber), and report ERB (Event Report BCSM, BCSM event report) response message to SCP.

Wherein, SSP reports the optional step of ERB response message to SCP, is optional.

Step 34: in calling procedure, if intelligent subscriber successfully calls ECT, then SSP reports ERB to SCP, reports ACR (Apply Charging Report, Apply Charging Report) simultaneously.

Wherein, carry in the ERB message and comprise event type, monitoring mode and DP designation criteria parameter in O-SSNotifyEvent/T-SSNotifyEvent information and this information, the relevant parameter of the SSNotifyEvent that carries in these parameters and the RRBE message that SCP issues is identical, wherein DP designation criteria parameter is except comprising the ECT type of service, also comprise the number of users that participates in this supplementary service, and corresponding Subscriber Number.

Carry the duration of call information of intelligent subscriber in the ACR message, this duration of call is for beginning to be billed to SSP and report the total duration of call of intelligent subscriber during this ACR message from replying.

Step 35:SCP determines charging policy according to the number of users and the user number information of supplementary service type, participation supplementary service after receiving described SSNotifyEvent, and the duration of call of intelligent subscriber in the ACR message called the duration of call before the success as ECT, the processing of chargeing of charging policy before calling successfully according to ECT, and call ticket before the success for intelligent subscriber generates ECT, there is not the ECT sign in this ticket.

SCP continues to issue AC message to SSP then, and conversation continues.

Step 36: when end of calling, SSP reports ERB message to SCP, and the event type that carries in this message is O-Disconnect/T-Diconnect, notice SCP call clearing; Report ACR message simultaneously.

Carry the duration of call information of intelligent subscriber in the ACR message, this duration of call is the total duration of call of intelligent subscriber (i.e. oneself begin to charge to end of calling end).

After step 37:SCP receives ERB message and ACR message, the duration of call that to obtain from this ACR message deducts the duration of call obtained the ACR message from last time as the duration of call after the ECT success, the processing of chargeing of charging policy after calling successfully according to ECT, and, carry the ECT sign in this ticket for intelligent subscriber generates ECT success ticket afterwards.

Then, SCP issues RC (Release Call, call release) message to SSP, discharges respective resources.

For supplementary services such as MPTY, CW, CH, be equally applicable to technique scheme, just need to revise DP designation criteria parameter.

After SCP affirmation intelligent subscriber has contracted MPTY, CW, CH, ECT supplementary service, the SSNotifyEvent of the corresponding supplementary service of configuration in the RRBE message that issues to SSP, and a plurality of DP designation criteria parameters can be set in a supplementary service call notification incident as required, be the type of a plurality of supplementary services, as ECT and/or CH and/or CW and/or MPTY; When intelligent subscriber called MPTY, CW, CH, ECT success, SSP reported corresponding supplementary service call notification incident to SCP.Therefore, O-CSI/VT-CSI service logic among the SCP can be easy to know whether intelligent subscriber supplementary service takes place, and can learn the duration of call of supplementary service success front and back, thus charge processing, and produce the charging bill before and after the supplementary service success.

Because MPTY, CW, CH supplementary service might repeatedly take place in the call process, therefore, before end of calling, the SSNotifyEvent that in the RRBE message that SSP issues, disposes for SCP, after a supplementary service takes place, should not separate and join, therefore, can be when SCP disposes SSNotifyEvent in the RRBE message that SSP issues, adopt the mode of reshuffling automatically, supplementary service this moment is called successfully event type and must be configured to EDP-N.Adopt the mode of reshuffling automatically, when SSP has reported after a supplementary service calls successfully incident, SCP need not to reconfigure SSNotifyEvent, just can realize when supplementary service taking place once more call successfully, SSP reports supplementary service to call successfully the purpose of incident once more, and the supplementary service type that reports before and after the SSP can be different.

Except that increasing supplementary service call notification incident, can also realize reporting corresponding supplementary service to call the message of success by the mode of expansion ACR message in addition to SCP.Embodiment comprises the steps: as shown in Figure 4

Step 41: after the intelligent subscriber request of making a call, SSP reports IDP message to SCP.

Carry Service Interaction Indicators Two parameter in this IDP message, ECT, MPTY, CW, CH supplementary service if intelligent subscriber has contracted then should be carried ECT/MPTY/CW/CH Treatment Indicator information in this parameter.

If supplementary service will occur in the MO end, SSP reports IDP message to SCP in the O-CSI IN process;

If supplementary service will occur in the MVT end, SSP reports IDP message to SCP in the VT-CSI IN process.

After step 42:SCP receives IDP message, check Service Interaction Indicators Two parameter, if carried ECT/MPTY/CW/CH Treatment Indicator information in this parameter, then determine this intelligent subscriber corresponding supplementary service of having contracted;

Issue RRBE message, AC message and Continue message to SSP then.

Step 43:SSP begins collecting charging information after receiving RRBE message that SCP issues and AC and Continue message, and reports the ERB response message to SCP.

Wherein, SSP reports the ERB response message optional to SCP, is optional.

Step 44: in calling procedure, if intelligent subscriber successfully initiates ECT/MPTY/CW/CH, then SSP reports ACR message to SCP, except the duration of call information that carries intelligent subscriber, also carry the ECT/MPTY/CW/CH supplementary service and call successfully sign and corresponding supplementary service type in this message.

Step 45, SCP call successfully sign according to the supplementary service of carrying in the ACR message and corresponding supplementary service type is determined charging policy, and with the duration of call of the intelligent subscriber that carries in the ACR message as the duration of call before the ECT/MPTY/CW/CH success, the processing of chargeing of charging policy before calling successfully according to supplementary service, and, there is not the ECT/MPTY/CW/CH sign in this ticket for intelligent subscriber generates ECT/MPTY/CW/CH success ticket before.

SCP continues to issue AC message to SSP then, and conversation continues.

Step 46: when end of calling, SSP reports ERB message to SCP, and the event type that carries in this message is O-Disconnect/T-Diconnect, notice SCP call clearing; Report ACR message simultaneously.

Carry the duration of call information of intelligent subscriber in the ACR message, this duration of call is the total duration of call of intelligent subscriber (i.e. oneself begin to charge to end of calling end).

After step 47:SCP receives ERB clear message and ACR message, the duration of call that to obtain from this ACR message deducts the duration of call obtained the ACR message from last time as the duration of call after the ECT/MPTY/CW/CH success, the processing of chargeing of charging policy after calling successfully according to supplementary service, and, carry the ECT/MPTY/CW/CH sign in this ticket for intelligent subscriber generates ECT/MPTY/CW/CH success ticket afterwards.

Issue RC message to SSP behind the SCP then, discharge respective resources.

Adopt above-mentioned two kinds of technical schemes, O-CSI/VT-CSI service logic among the SCP can be easy to know whether intelligent subscriber supplementary service takes place, and can accurately determine the successfully duration of call of front and back of supplementary service, therefore, for this intelligent subscriber, not only can select the monthly rent charging way, but also can select whole charging way or independent counting mode, when selecting whole charging way, can accurately judge the air time ratio of supplementary service success front and back, can determine concrete discount ratio, make whole charging way become a kind of accurate charging way; When selecting the independent counting mode, can adopt different charging policy at supplementary service success front and back, and charge accurately.Therefore the means of chargeing are flexibly provided for operator.The whole charging way of concrete employing still is the independent counting mode, is determined by operator, but needs MSC and SCP to be consistent, and therefore when SCP deducted fees, MSC also generated ticket synchronously, was used for the accounting checking of chargeing.

The present invention also provides a kind of system that realizes supplementary service charging for intelligent user, and as shown in Figure 5, this system comprises: notification module, charge information reporting module and supplementary service charging processing module are called successfully in supplementary service.Wherein,

The success message notification module is called in supplementary service, is arranged among the SSP, and its function is: when intelligent subscriber successfully initiates supplementary service, report corresponding supplementary service to call success message to the supplementary service charging processing module in calling procedure;

The charge information reporting module is arranged among the SSP, and its function is: the charge information that reports intelligent subscriber to the supplementary service charging processing module;

The supplementary service charging processing module, be arranged among the SCP, its function is: the charge information that calls success message and intelligent subscriber according to supplementary service is determined the duration of call of described supplementary service before and after calling successfully, and the processing of chargeing of the charging policy before and after calling successfully according to supplementary service.

The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
